RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Sector Risk. A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.

·   Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

·   Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

·   Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund’s Adviser actively manages the Fund’s portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser’s standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates;

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in variable rate instruments that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund’s investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund’s investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio’s DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

INDUSTRY CONCENTRATION

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio’s DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund’s investment returns and/or the Fund’s ability to achieve its investment objective.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses.  Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.  The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months.  Companies typically issue commercial paper to pay for current expenditures.  Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper.  If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider’s obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obliga­tions other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States.  Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities.  Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

·   it is organized under the laws of, or has a principal office located in, another country;

·   the principal trading market for its securities is in another country; or

·   it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security’s holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction.  This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements.  The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER CREDIT RISK

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor’s and Moody’s Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk.  Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security’s spread may also increase if the security’s rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securi­ties with longer maturities. Money market funds try to mini­mize this risk by purchasing short-term securities.

SECTOR RISKS

A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund’s portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund’s investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

RISKS OF FOREIGN INVESTING

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press.  In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund’s investments.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net pur­chases on days on which short-term yields rise will cause the Fund’s yield to increase. The larger the amount that must be invested or the greater the differ­ence between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV.  NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time.  The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Cash II Shares, Institutional Service Shares and Class K Share, each representing interests in a single portfolio of securities. Effective December 31, 2010, the Fund's Class K Shares will be redesignated as Class R Shares. This Prospectus relates only to Cash II Shares. All Share classes have different  expenses which affect their performance. The additional classes of Shares, which are offered by separate Prospectus, may be preferable for shareholders purchasing $25,000 or more.  Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to retail and private banking customers of financial institutions or to individuals, directly or through financial inter­mediaries.  Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12B-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to 0.25% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund’s Cash II Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares.  Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different  marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts.  Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount. The minimum initial and subsequent investment amounts for IRAs are $250 and $100, respectively. There is no minimum initial or subsequent investment amount required for employer-sponsored retirement plans; however, such accounts remain subject the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus.

An account may be opened with a smaller amount as long as the $25,000 minimum is reached within 90 days. An institutional investor’s minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund.  If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order.  Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company

Boston, MA

Dollar Amount of Wire

ABA Number 011000028

BNF:  23026552

Attention:  Federated EDGEWIRE

Wire Order Number, Dealer Number or Group Number

Nominee/Institution Name

Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds

30 Dan Road

Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund’s transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

BY AUTOMATIC INVESTMENTS

You may establish an account with your financial intermediary to automatically purchase Shares on predetermined dates or when your bank account reaches a certain level. Under this program, participating financial intermediaries are responsible for prompt transmission of orders and may charge you for this service. You should read this Prospectus along with your financial intermediary’s agreement or materials describing this service.

BY DIRECT DEPOSIT

You may complete an application with State Street Bank and Trust Company to have your Social Security, Railroad Retirement, VA Compensation or Pension, Civil Service Retirement and certain other retirement payments invested directly into the Fund. The application must be filed with State Street Bank and Trust Company before direct deposit may begin. Allow 60 to 90 days for the application to be processed.

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from the same share class of another Federated fund. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY SYSTEMATIC INVESTMENT PROGRAM

Once you have opened an account, you may automatically purchase additional Shares on a regular basis by completing the SIP section of the New Account Form or by contacting the Fund or your financial intermediary. The minimum investment amount for SIPs is $50.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

RETIREMENT INVESTMENTS

You may purchase Shares as retirement investments (such as qualified plans and IRAs or transfer or rollover of assets). Call your financial intermediary or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

·   through a financial intermediary if you purchased Shares through a financial intermediary; or

·   directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund.  If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day’s dividend.  If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds

30 Dan Road

Canton, MA 02021

All requests must include:

·   Fund Name and Share Class, account number and account registration;

·   amount to be redeemed or exchanged;

·   signatures of all shareholders exactly as registered; and

·   if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

·   your redemption will be sent to an address other than the address of record;

·   your redemption will be sent to an address of record that was changed within the last 30 days;

·   a redemption is payable to someone other than the shareholder(s) of record; or

·   transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. A notary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

·   an electronic transfer to your account at a financial institution that is an ACH member; or

·   wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

Any attempt to redeem Shares through checkwriting or debit card before the purchase instrument has cleared will be automatically rejected.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

SYSTEMATIC WITHDRAWAL/EXCHANGE PROGRAM

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.  Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

CHECKWRITING

You may request checks to redeem your Fund Shares. Your account will continue to receive the daily dividend declared on the Shares being redeemed until the check is presented for payment.

DEBIT CARD

You may request a debit card account that allows you to redeem Shares. There is an annual fee for this service that the Fund will automatically deduct from your account.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund may establish alternative days for payment of dividends each month at the election of your financial intermediary’s firm.  Each investment firm must elect the same payment date for all shareholder accounts that are traded through the same system maintained by the firm.  Unless the transfer agent is otherwise notified, each investment firm will be deemed to elect to receive dividends on the last day of each month.  If you purchase Shares directly from the Fund, you will receive dividends on the last day of each month.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund’s daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated’s website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $25,000 or in the case of IRAs $250. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its DWAM and WAL, will be posted on the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

In addition, from time to time (for example, during periods of unusual market conditions), additional information regarding the Fund’s portfolio holdings and/or composition may be posted to Federated’s website. If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.50% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board’s review of the Fund’s investment advisory contract is available in the Fund’s Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund’s financial performance for its past five fiscal years. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees).

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Sector Risk. A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.

·   Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

·   Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

·   Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund’s Adviser actively manages the Fund’s portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser’s standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates;

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in variable rate instruments that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund’s investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund’s investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio’s DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

INDUSTRY CONCENTRATION

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio’s DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund’s investment returns and/or the Fund’s ability to achieve its investment objective.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses.  Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.  The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months.  Companies typically issue commercial paper to pay for current expenditures.  Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper.  If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider’s obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obliga­tions other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States.  Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities.  Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

·   it is organized under the laws of, or has a principal office located in, another country;

·   the principal trading market for its securities is in another country; or

·   it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security’s holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction.  This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements.  The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER CREDIT RISK

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor’s and Moody’s Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk.  Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security’s spread may also increase if the security’s rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securi­ties with longer maturities. Money market funds try to mini­mize this risk by purchasing short-term securities.

SECTOR RISKS

A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund’s portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund’s investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

RISKS OF FOREIGN INVESTING

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press.  In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund’s investments.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net pur­chases on days on which short-term yields rise will cause the Fund’s yield to increase. The larger the amount that must be invested or the greater the differ­ence between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV.  NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time.  The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Cash II Shares, Institutional Service Shares and Class K Share, each representing interests in a single portfolio of securities. This Prospectus relates only to Class K Shares. All Share classes have different  expenses which affect their performance. The additional classes of Shares, which are offered by separate prospectus, may be preferable for shareholders purchasing $25,000 or more. Contact your financial intermediary or call 1-800-341-7400for more information concerning the other classes.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to 401(k) plans, 457 plans, employer sponsored 403(b) plans, profit sharing and money purchase pension plans, defined benefit plans and non-qualified deferred compensation plans and IRA Rollovers from such plans, directly or through investment professionals.  Class K Shares are generally available only to retirement plans where plan level omnibus accounts are held on the books of the Fund. Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12B-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to 0.50% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund’s Class K Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares.  Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different  marketing fees.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive  Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The minimum initial and subsequent investment amounts for IRAs are $250 and $100, respectively.

An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund.  If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order.  Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company

Boston, MA

Dollar Amount of Wire

ABA Number 011000028

BNF:  23026552

Attention:  Federated EDGEWIRE

Wire Order Number, Dealer Number or Group Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds

30 Dan Road

Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund’s transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

BY AUTOMATIC INVESTMENTS

You may establish an account with your financial intermediary to automatically purchase Shares on predetermined dates or when your bank account reaches a certain level. Under this program, participating financial intermediaries are responsible for prompt transmission of orders and may charge you for this service. You should read this Prospectus along with your financial intermediary’s agreement or materials describing this service.

BY DIRECT DEPOSIT

You may complete an application with State Street Bank and Trust Company to have your Social Security, Railroad Retirement, VA Compensation or Pension, Civil Service Retirement and certain other retirement payments invested directly into the Fund. The application must be filed with State Street Bank and Trust Company before direct deposit may begin. Allow 60 to 90 days for the application to be processed.

You may purchase Shares through an exchange from the same share class of another Federated fund. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY SYSTEMATIC INVESTMENT PROGRAM

Once you have opened an account, you may automatically purchase additional Shares on a regular basis by completing the SIP section of the New Account Form or by contacting the Fund or your financial intermediary. The minimum investment amount for SIPs is $50.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

·   through a financial intermediary if you purchased Shares through a financial intermediary; or

·   directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund.  If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day’s dividend.  If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds

30 Dan Road

Canton, MA 02021

All requests must include:

·   Fund Name and Share Class, account number and account registration;

·   amount to be redeemed or exchanged;

·   signatures of all shareholders exactly as registered; and

·   if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

·   your redemption will be sent to an address other than the address of record;

·   your redemption will be sent to an address of record that was changed within the last 30 days;

·   a redemption is payable to someone other than the shareholder(s) of record; or

·   transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. A notary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

·   an electronic transfer to your account at a financial institution that is an ACH member; or

·   wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

SYSTEMATIC WITHDRAWAL/EXCHANGE PROGRAM

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.  Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund’s daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated’s website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $250. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month.

Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month. The summary portfolio composition information may include identification of the Fund’s top ten holdings and percentage breakdowns of the portfolio by credit quality tier, type of security and effective maturity range.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website.

Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

In addition, from time to time (for example, during periods of unusual market conditions), additional information regarding the Fund’s portfolio holdings and/or composition may be posted to Federated’s website. If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.50% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board’s review of the Fund’s investment advisory contract is available in the Fund’s Annual  Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund’s financial performance for its past five fiscal years. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

This information has been audited by Ernst & Young LLP, an independent registered public accounting firm, whose report, along with the Fund’s audited financial statements, is included in the Annual Report.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees).

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Sector Risk. A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.

·   Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

·   Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

·   Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund’s Adviser actively manages the Fund’s portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser’s standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates;

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in variable rate instruments that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund’s investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund’s investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio’s DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

INDUSTRY CONCENTRATION

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio’s DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund’s investment returns and/or the Fund’s ability to achieve its investment objective.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses.  Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.  The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months.  Companies typically issue commercial paper to pay for current expenditures.  Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper.  If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider’s obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obliga­tions other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States.  Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities.  Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

·   it is organized under the laws of, or has a principal office located in, another country;

·   the principal trading market for its securities is in another country; or

·   it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security’s holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction.  This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements.  The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER CREDIT RISK

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor’s and Moody’s Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk.  Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security’s spread may also increase if the security’s rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securi­ties with longer maturities. Money market funds try to mini­mize this risk by purchasing short-term securities.

SECTOR RISKS

A substantial part of the Fund’s portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund’s portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund’s investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

RISKS OF FOREIGN INVESTING

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press.  In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund’s investments.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net pur­chases on days on which short-term yields rise will cause the Fund’s yield to increase. The larger the amount that must be invested or the greater the differ­ence between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV.  NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time.  The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Cash II Shares, Class K Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. Effective December 31, 2010, the Fund's Class K Shares will be redesignated as Class R Shares. This Prospectus relates only to Institutional Service Shares. All Share classes have different  expenses which affect their performance.   Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to retail and private banking customers of financial institutions or to individuals, directly or through financial inter­mediaries.  Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts.  Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is reached within 90 days. An institutional investor’s minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund.  If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order.  Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company

Boston, MA

Dollar Amount of Wire

ABA Number 011000028

BNF:  23026552

Attention:  Federated EDGEWIRE

Wire Order Number, Dealer Number or Group Number

Nominee/Institution Name

Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds

30 Dan Road

Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund’s transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

BY AUTOMATIC INVESTMENTS

You may establish an account with your financial intermediary to automatically purchase Shares on predetermined dates or when your bank account reaches a certain level. Under this program, participating financial intermediaries are responsible for prompt transmission of orders and may charge you for this service. You should read this Prospectus along with your financial intermediary’s agreement or materials describing this service.

BY DIRECT DEPOSIT

You may complete an application with State Street Bank and Trust Company to have your Social Security, Railroad Retirement, VA Compensation or Pension, Civil Service Retirement and certain other retirement payments invested directly into the Fund. The application must be filed with State Street Bank and Trust Company before direct deposit may begin. Allow 60 to 90 days for the application to be processed.

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from the same share class of another Federated fund. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY SYSTEMATIC INVESTMENT PROGRAM

Once you have opened an account, you may automatically purchase additional Shares on a regular basis by completing the SIP section of the New Account Form or by contacting the Fund or your financial intermediary. The minimum investment amount for SIPs is $50.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

·   through a financial intermediary if you purchased Shares through a financial intermediary; or

·   directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund.  If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day’s dividend.  If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds

30 Dan Road

Canton, MA 02021

All requests must include:

·   Fund Name and Share Class, account number and account registration;

·   amount to be redeemed or exchanged;

·   signatures of all shareholders exactly as registered; and

·   if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

·   your redemption will be sent to an address other than the address of record;

·   your redemption will be sent to an address of record that was changed within the last 30 days;

·   a redemption is payable to someone other than the shareholder(s) of record; or

·   transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. A notary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

·   an electronic transfer to your account at a financial institution that is an ACH member; or

·   wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

Any attempt to redeem Shares through checkwriting or debit card before the purchase instrument has cleared will be automatically rejected.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

SYSTEMATIC WITHDRAWAL/EXCHANGE PROGRAM

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.  Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

CHECKWRITING

You may request checks to redeem your Fund Shares. Your account will continue to receive the daily dividend declared on the Shares being redeemed until the check is presented for payment.

DEBIT CARD

You may request a debit card account that allows you to redeem Shares. There is an annual fee for this service that the Fund will automatically deduct from your account.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund’s daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated’s website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $25,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month.

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.50% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board’s review of the Fund’s investment advisory contract is available in the Fund’s Annual  Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Automated Cash Management Trust to Federated Automated Cash Management Trust on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (the “Board”) has established three classes of shares of the Fund, known as Cash II Shares, Class K Shares and Institutional Service Shares (Shares). Effective December 31, 2010, the Fund’s Class K Shares will be redesignated as

Class R Shares. This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund's Prospectus.  The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective.  The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

SECURITIES DESCRIPTIONS AND TECHNIQUES

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities.  Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The highest rating category of a nationally recognized statistical rating organization (NRSRO) is determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (S&P), Prime-1 by Moody’s Investors Service (“Moody’s”), F-1+ or F-1 by Fitch Ratings (“Fitch”) or R-1 (high), R-1 (middle) or R-1 (low) by Dominion Bond Rating Service (DBRS) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund.  The Fund's principal risks are described in its Prospectus.  The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

LEVERAGE RISKS

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

CALL RISKS

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH THE INVESTMENT ACTIVITIES OF OTHER ACCOUNTS

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

RISKS ASSOCIATED WITH TEMPORARY LIQUIDITY GUARANTEE PROGRAM

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective (and Policies) and Investment Limitations

The Fund’s investment objective is to provide stability of principal and current income consistent with stability of principal.

The Fund invests in high-quality money market instruments which include, but are not limited to, instruments of domestic and foreign banks and savings and loans, commercial paper, marketable obligations and repurchase agreements.

The Fund invests only in instruments denominated and payable in U.S. dollars.

The Fund may invest in commercial paper issued in reliance on the exemption from registration afforded by Section 4 (2) of the Securities Act of 1933. Section 4 (2) paper is restricted as to disposition under federal securities law and is generally sold to institutional investors, such as the Fund, who agree that they are purchasing the paper for investment purposes and not with a view to public distribution. Any resale by the purchaser must be in an exempt transaction. Section 4 (2) paper is normally resold through or with the assistance of an issuer or investment dealers who make a market in Section 4 (2) paper, thus providing liquidity. Therefore, the Fund’s Adviser considers the legally restricted but quite saleable Section 4 (2) paper to be liquid.

The fundamental investment objective and policies may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (the “1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interest therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Diversification

The Fund is a “diversified company” within the meaning of the 1940 Act, as amended, and any rules, regulations, or interpretations thereunder.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge, or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector, and the financial services sector to include banks, broker-dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset-backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

DETERMINING MARKET VALUE OF SECURITIES

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost.  Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity.  If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

RULE 12b-1 PLAN (CASH II SHARES AND CLASS K SHARES)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares.  The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares.  Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees.  The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries.  Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

FEDERAL INCOME TAX

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust's other portfolios will be separate from those realized by the Fund.

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

VOTING PROXIES ON FUND PORTFOLIO SECURITIES

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio.  The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor.  This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote.  A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes.  Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote.  Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication.  Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted.  If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions.  If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company.  If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did.  Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board.  In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund  may receive nonpublic information about Fund portfolio holdings for purposes relating to their services.  The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies.  Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest.  A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund.  The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders.  In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply.  No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information.  Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security.  Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided.  Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished.  The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

BROKERAGE TRANSACTIONS AND INVESTMENT ALLOCATION

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year or Start of Performance periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

		7-Day Period		1 Year	5 Years	10 Years
Cash II Shares:
Total Return		N/A		0.01%	2.59%	2.26%
Yield		0.01%		N/A	N/A	N/A
Effective Yield		0.01%		N/A	N/A	N/A
Institutional Service Shares:
Total Return		N/A		0.01%	2.73%	2.42%
Yield		0.01%		N/A	N/A	N/A
Effective Yield		0.01%		N/A	N/A	N/A
	7-Day Period		1 Year	5 Years	Start of Performance on 9/29/2006
Class K Shares:
Total Return	N/A		0.01%		1.98%
Yield	0.01%		N/A	N/A	N/A
Effective Yield	0.01%		N/A	N/A	N/A

TOTAL RETURN

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

YIELD AND EFFECTIVE YIELD

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to Shareholders of Federated Automated Cash Management Trust dated July 31, 2010.

Investment Ratings

STANDARD & POOR’S (S&P) SHORT-TERM MUNICIPAL OBLIGATION RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1--Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2--Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P VARIABLE RATE DEMAND NOTES (VRDNS) AND TENDER OPTION BONDS (TOBS) RATINGS

S&P assigns "dual" ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

S&P COMMERCIAL PAPER (CP) RATINGS

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1--A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor's.  The obligor's capacity to meet its financial commitment on the obligation is strong.  Within this category, certain obligations are designated with a plus sign (+).  This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong.

A-2--A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories.  However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory.

S&P LONG-TERM DEBT RATINGS

AAA--An obligation rated “AAA” has the highest assigned by Standard & Poor's.  The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

AA--An obligation rated “AA” differs from the highest rated obligations only in small degree.  The obligor's capacity to meet its financial commitment on the obligation is very strong.

A--An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories.  However, the obligor's capacity to meet its financial commitment on the obligation is still strong.

MOODY’S INVESTORS SERVICE (“MOODY’S”) SHORT-TERM MUNICIPAL OBLIGATIONS RATINGS

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1--This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2--This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MOODY’S VARIABLE RATE DEMAND NOTES (VRDNS) AND TENDER OPTION BONDS (TOBS) RATINGS

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

MOODY’S COMMERCIAL PAPER (CP) RATINGS

Prime-1--Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2--Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

MOODY’S  LONG-TERM DEBT RATINGS

Aaa--Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edged." Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa--Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A--Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR--Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1)--The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2)--The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3)--The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

FITCH RATINGS SHORT-TERM DEBT RATING DEFINITIONS

F-1--Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the "best" credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a "+" is added to the assigned rating.

F-2--Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3--Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

FITCH RATINGS LONG-TERM DEBT RATING DEFINITIONS

AAA--Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA--Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A--High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB--Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

FITCH RATINGS COMMERCIAL PAPER RATING DEFINITIONS

F-1--Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the "best" credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a "+" is added to the assigned rating.

F-2--Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

DBRS SHORT-TERM DEBT AND COMMERCIAL PAPER RATING DEFINITIONS

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high)--Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle)--Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

R-1 (low)--Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low)--Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS LONG-TERM DEBT RATING DEFINITIONS

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

“AAA”--Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA”--Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A”--Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

“High” or “low”--grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and "low" grades are not used for the AAA category.

A.M. BEST LONG-TERM DEBT RATINGS

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due.  These ratings are assigned to debt and preferred stock issues.

aaa—Exceptional.  Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa—Very Strong.  Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a—Strong.  Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb—Adequate.  Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category.  A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change.  Ratings prefixed with an (“i”) denote indicative ratings.  Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. BEST SHORT-TERM DEBT RATINGS

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

AMB-1+—Strongest.  Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1—Outstanding.  Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2—Satisfactory.  Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3—Adequate.  Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. BEST RATING OUTLOOK

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months.  Public Data Ratings are not assigned an Outlook.  Ratings Outlooks are as follows:

Positive—Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

Negative—Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable—Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

Example

This Example is intended to help you compare the cost of investing in the Fund's Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$135
3 Years	$421
5 Years	$729
10 Years	$1,601

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (Freddie Mac), the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (Ginnie Mae). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's investment Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

5Table Of Contents

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates;
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objectives.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities. The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

10Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to

11Table Of Contents

changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

12Table Of Contents

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 4:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to customers of financial institutions, such as banks, fiduciaries, custodians of public funds, investment advisers and broker/dealers, or to individuals, directly or through financial intermediaries. Shares of the Fund are available primarily through investment firms that clear through Pershing LLC.

Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

14Table Of Contents

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.55% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

15Table Of Contents

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500. The required minimum subsequent investment amount is $100.

The minimum initial and subsequent investment amounts for IRAs are $250 and $100, respectively.

An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

Call your financial intermediary or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

20Table Of Contents

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);
• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of Federated Government Reserves Fund and Federated Municipal Trust. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction.

The Fund may modify or terminate the exchange privilege at any time.

21Table Of Contents

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund. Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund does not issue Share certificates.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

22Table Of Contents

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500 or in the case of IRAs $250. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

24Table Of Contents

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.30% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material

25Table Of Contents

adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Trust may offer separate series of shares representing interests in separate portfolios of securities. The Fund was established as a portfolio of the Trust on December 31, 2004.

The Fund’s investment adviser is Federated Investment Management Company (Adviser).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

2Table Of Contents

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more Nationally Recognized Statistical Rating Organizations (NRSROs) or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7’s limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund’s portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

FUNDAMENTAL INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with the stability of principal and liquidity. This investment objective cannot be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer. As a matter of non-fundamental policy, the Fund complies with the diversification requirements of Rule 2a-7, which are more rigorous.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (1940 Act).

4Table Of Contents

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Investing in Restricted Securities

The Fund may invest in securities subject to restrictions on resale under federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the commodities restriction, investments in transactions involving futures contracts and options forward currency contracts, swap transactions and other financial contracts that settle by payment in cash are deemed not to be investments in commodities.

In applying the Fund’s concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset backed securities will be classified according to the underlying assets securing

5Table Of Contents

such securities. To conform to the current view of the SEC staff that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration tests as long as the policy of the SEC remains in effect. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Rule 12b-1 Plan

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

6Table Of Contents

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

7Table Of Contents

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

On behalf of the Board, the Audit Committee plays a key role overseeing the Fund’s financial reporting and valuation risks. The Audit Committee meets regularly with the Fund’s Principal Financial Officer and outside auditors, as well as with Federated’s Chief Audit Executive to discuss financial reporting and audit issues, including risks relating to financial controls.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

14Table Of Contents

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

15Table Of Contents

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

Portfolio Holdings Information

This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible

17Table Of Contents

that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

Custodian

The Bank of New York Mellon, New York, New York, is custodian for the securities and cash of the Fund.

Transfer Agent And Dividend Disbursing Agent

State Street Bank and Trust Company, the Fund’s registered transfer agent, maintains all necessary shareholder records.

Independent Registered Public Accounting Firm

The independent registered public accounting firm for the Fund, Ernst & Young LLP, conducts its audits in accordance with the standards of the Public Company Accounting Oversight Board (United States), which require it to plan and perform its audits to provide reasonable assurance about whether the Fund’s financial statements and financial highlights are free of material misstatement.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

18Table Of Contents

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year and Start of Performance periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Year	Start of Performance on 2/25/2005
Total Return	NA	0.00%	2.45%	2.43%
Yield	0.00%	NA	NA	NA
Effective Yield	0.00%	NA	NA	NA

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to Shareholders of Federated Capital Reserves Fund dated July 31, 2010.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

19Table Of Contents

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

20Table Of Contents

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Example

This Example is intended to help you compare the cost of investing in the Fund's Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$132
3 Years	$412
5 Years	$713
10 Years	$1,568

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

2Table Of Contents

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and

reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to government investments in its name, the SEC requires the Fund to notify shareholders in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

6Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

7Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases,

8Table Of Contents

the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

9Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 4:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to customers of financial institutions, such as banks, fiduciaries, custodians of public funds, investment advisers and broker/dealers, or to individuals, directly or through financial intermediaries. Shares of the Fund are available primarily through investment firms that clear through Pershing LLC.

Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.55% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

10Table Of Contents

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500. The required minimum subsequent investment amount is $100.

11Table Of Contents

The minimum initial and subsequent investment amounts for IRAs are $250 and $100, respectively.

An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

16Table Of Contents

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of Federated Capital Reserves Fund or Federated Municipal Trust. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction.

The Fund may modify or terminate the exchange privilege at any time.

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund. Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

17Table Of Contents

Share Certificates

The Fund does not issue Share certificates.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500 or in the case of IRAs $250. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains

18Table Of Contents

are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.30% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Trust may offer separate series of shares representing interests in separate portfolios of securities. The Fund was established as portfolio of the Trust on December 31, 2004.

The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury or Government securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Government Mortgage-Backed Securities

Government mortgage-backed securities represent interests in pools of mortgages issued by federal agencies or instrumentalities. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Government mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest form of mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in securities of other investment companies, including the securities of affiliated money market funds, as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

Credit Enhancement

The Fund may invest in securities with credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

The Fund will only invest in securities with credit enhancement if the entity providing the credit enhancement is the U.S. government or an agency or instrumentality of the U.S. government.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to security’s holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

2Table Of Contents

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due) payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a fund holding mortgage-backed securities.

For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities.

Conversely, when interest rates rise, the values of mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of mortgage-backed securities, and cause their value to decline more than traditional fixed-income securities.

3Table Of Contents

Generally, mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of a mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (“the spread”). An increase in the spread will cause the price of the mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

Fundamental investment objective

The investment objective of the Fund is current income consistent with the stability of principal and liquidity. This investment objective cannot be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer. As a matter of non-fundamental policy, the Fund complies with the diversification requirements of Rule 2a-7, which are more rigorous.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

4Table Of Contents

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Purchases on Margin

The Fund will not purchase securities on margin, provided that a Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Investing in Restricted Securities

A Fund may invest in securities subject to restrictions on resale under federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, a Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the commodities restriction, investments in transactions involving futures contracts and options forward currency contracts, swap transactions and other financial contracts that settle by payment in cash are deemed not to be investments in commodities.

In applying the Funds’ concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset backed securities will be classified according to the underlying assets securing such securities. To conform to the current view of the SEC staff that only domestic bank instruments may be excluded from industry concentration limitations, the Funds will not exclude foreign bank instruments from industry concentration tests as long as the policy of the SEC remains in effect. The Funds will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Rule 12b-1 Plan

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of

6Table Of Contents

the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

7Table Of Contents

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A special meeting of shareholders will be called by the Board upon the written request of shareholders who own at least 10% of the Trust’s outstanding shares of series entitled to vote.

As of September 7, 2010, the following shareholders owned of record, beneficially, or both, 5% or more of outstanding Shares: Pershing LLC, Jersey City, NJ, owned approximately 9,491,424,388 shares (85.95%); and Pershing LLC, Jersey City, NJ, owned approximately 1,550,509,452 shares (14.04%).

Shareholders owning 25% or more of outstanding Shares may be in control and be able to affect the outcome of certain matters presented for a vote of shareholders.

Pershing LLC is organized in the state of Delaware as a foreign LLC and is a subsidiary of the Bank of New York Company, organized in the state of New York.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

BOARD LEADERSHIP STRUCTURE

As required under the terms of certain regulatory settlements, the Chairman of the Board is not an interested person of the Fund and neither the Chairman, nor any firm with which the Chairman is affiliated, has a prior relationship with Federated or its affiliates or (other than his position as a Trustee) with the Fund.

Committees of the Board

Board Committee	Committee Members	Committee Functions	Meetings Held During Last Fiscal Year
Executive	John F. Donahue Peter E. Madden John S. Walsh	In between meetings of the full Board, the Executive Committee generally may exercise all the powers of the full Board in the management and direction of the business and conduct of the affairs of the Trust in such manner as the Executive Committee shall deem to be in the best interests of the Trust. However, the Executive Committee cannot elect or remove Board members, increase or decrease the number of Trustees, elect or remove any Officer, declare dividends, issue shares or recommend to shareholders any action requiring shareholder approval.	Two
Audit	Nicholas P. Constantakis Charles F. Mansfield, Jr. Thomas M. O’Neill John S. Walsh	The purposes of the Audit Committee are to oversee the accounting and financial reporting process of the Fund, the Fund’s internal control over financial reporting and the quality, integrity and independent audit of the Fund’s financial statements. The Committee also oversees or assists the Board with the oversight of compliance with legal requirements relating to those matters, approves the engagement and reviews the qualifications, independence and performance of the Fund’s independent registered public accounting firm, acts as a liaison between the independent registered public accounting firm and the Board and reviews the Fund’s internal audit function.

Nominating	John T. Conroy, Jr. Nicholas P. Constantakis John F. Cunningham Maureen Lally-Green Peter E. Madden Charles F. Mansfield, Jr. R. James Nicholson Thomas M. O’Neill John S. Walsh James F.

The Committee will consider candidates recommended by shareholders, Independent Trustees, officers or employees of any of the Fund’s agents or service providers and counsel to the Fund. Any shareholder who desires to have an individual considered for nomination by the Committee must submit a recommendation in writing to the Secretary of the Fund, at the Fund’s address appearing on the back cover of this SAI. The recommendation should include the name and address of both the shareholder and the candidate and detailed information concerning the candidate’s qualifications and experience. In identifying and evaluating candidates for consideration, the Committee shall consider such factors as it deems appropriate. Those factors will ordinarily include: integrity, intelligence, collegiality, judgment, diversity, skill, business and other experience, qualification as an “Independent Trustee,” the existence of material relationships which may create the appearance of a lack of independence, financial or accounting knowledge and experience and dedication and willingness to devote the time and attention necessary to fulfill Board responsibilities.

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

On behalf of the Board, the Audit Committee plays a key role overseeing the Fund’s financial reporting and valuation risks. The Audit Committee meets regularly with the Fund’s Principal Financial Officer and outside auditors, as well as with Federated’s Chief Audit Executive to discuss financial reporting and audit issues, including risks relating to financial controls.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

14Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

15Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

16Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five year and Start of Performance periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year		5 Year	Start of Performance on 2/25/2005
Total Return	N/A	0.00%	2.21%		2.20%
Yield	0.00%	N/A	N/A		N/A
Effective Yield	0.00%	N/A	N/A		N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

18Table Of Contents

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Example

This Example is intended to help you compare the cost of investing in the Fund's Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$136
3 Years	$425
5 Years	$734
10 Years	$1,613

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the federal alternative minimum tax for individuals and corporations (AMT). The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities, such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds, and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the federal alternative minimum tax for individuals and corporations (AMT). The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

5Table Of Contents

The investment adviser (“Adviser”) for the Fund targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others) current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity range when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar- weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns.

The Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields. The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of nationally recognized statistical rating organizations (NRSROs).

In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available. In addition, the Adviser may invest in securities subject to the federal alternative minimum tax (AMT) for individuals and corporations.

The Adviser structures the portfolio by investing in variable rate demand instruments and municipal notes, as well as other permissible investments as described in this prospectus and in the Fund's Statement of Additional Information (SAI).

Because the Fund refers to municipal investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the annual interest income that it distributes will be exempt from federal regular income tax. This policy may not be changed without shareholder approval.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions

6Table Of Contents

(for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

7Table Of Contents

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain

8Table Of Contents

airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. The Fund may invest in bonds subject to AMT.

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

9Table Of Contents

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or sub-categories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

10Table Of Contents

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors,

11Table Of Contents

such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests. Income from the Fund also may be subject to the AMT.

12Table Of Contents

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

13Table Of Contents

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to customers of financial institutions, such as banks, fiduciaries, custodians of public funds, investment advisers and broker/dealers, or to

14Table Of Contents

individuals, directly or through financial intermediaries. Shares of the Fund are available primarily through investment firms that clear through Pershing LLC. The Fund may not be a suitable investment for retirement plans.

Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.55% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500. The required minimum subsequent investment amount is $100.

An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);

20Table Of Contents

• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

Any attempt to redeem Shares through checkwriting or debit card before the purchase instrument has cleared will be automatically rejected.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of Federated Capital Reserves Fund or Federated Government Reserves Fund. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction.

The Fund may modify or terminate the exchange privilege at any time.

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund. Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum

21Table Of Contents

initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

CHECKWRITING

You may request checks to redeem your Fund Shares. Your account will continue to receive the daily dividend declared on the Shares being redeemed until the check is presented for payment.

DEBIT CARD

You may request a debit card account that allows you to redeem Shares. There is an annual fee for this service that the Fund will automatically deduct from your account.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund does not issue Share certificates.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions, dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be

22Table Of Contents

converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.30% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

25Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Fund’s investment adviser is Federated Investment Management Company (Adviser).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund may invest:

Municipal Leases (A Type of Tax-Exempt, Fixed-Income Security)

Municipalities may enter into leases for equipment or facilities. In order to comply with state public financing laws, these leases are typically subject to annual appropriation. In other words, a municipality may end a lease, without penalty, by not providing for the lease payments in its annual budget. After the lease ends, the lessor can resell the equipment or facility but may lose money on the sale. The Fund may invest in securities supported by pools of municipal leases. The most common type of lease-backed securities are certificates of participation (COPs). However, the Fund may also invest directly in individual leases.

Callable Securities (A Type of Tax-Exempt, Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Certain callable securities invested in by the Fund also may be callable by parties other than the issuer. Callable securities are subject to call risks.

Zero-Coupon Securities (A Type of Tax-Exempt, Fixed-Income Security)

Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero-coupon security.

There are many forms of zero-coupon securities. Some are issued at a discount and are referred to as zero-coupon or capital-appreciation bonds. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

Tax Increment Financing Bonds (A Type of Tax-Exempt, Fixed-Income Security)

Tax increment financing (TIF) bonds are payable from increases in taxes or other revenues attributable to projects within the TIF district. For example, a municipality may issue TIF bonds to redevelop a commercial area. The TIF bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could fail to pay principal or interest if merchants’ sales, and related tax collections, failed to increase as anticipated.

1Table Of Contents

Municipal Mortgage-Backed Securities (A Type of Tax-Exempt, Fixed-Income Security)

Municipal mortgage-backed securities are special revenue bonds the proceeds of which may be used to provide mortgage loans for single family homes or to finance multifamily housing. Municipal mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable rates. Interests in pools of adjustable-rate mortgages are known as ARMs. Municipal mortgage-backed securities generally have fixed interest rates.

Municipal mortgage-backed securities come in a variety of forms. The simplest forms of municipal mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other municipal mortgage-backed securities may have more complicated financial structures.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Temporary Investments

The Fund may make temporary investments in taxable, fixed-income securities and the following other taxable securities:

Treasury Securities (A Type of Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Type of Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

2Table Of Contents

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Bank Instruments (A Type of Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Corporate Debt Securities (A Type of Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default. The short maturity of commercial paper generally reduces both the market and credit risks as compared to other debt securities of the same issuer.

Repurchase Agreements (A Type of Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

3Table Of Contents

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks. In addition to taxable repurchase agreements, the Fund also may invest in municipal repurchase agreements as a non-principal investment.

Reverse Repurchase Agreements (A Type of Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase. In addition to taxable reverse repurchase agreements, the Fund also may invest in municipal reverse repurchase agreements as a non-principal investment.

INVESTMENT RATINGS

An NRSRO’s rating category is determined without regard for sub-categories and gradations. For example, securities rated F-1+ or F-1 by Fitch Ratings are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one NRSRO can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective (and Policies) and Investment Limitations

The investment objective of the Fund is to provide current income which is exempt from federal regular income tax consistent with stability of principal. The Fund will invest its assets so that at least 80% of its annual interest income that the Fund distributes is exempt from federal regular income tax.

This investment objective and policy cannot be changed without shareholder approval.

4Table Of Contents

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer. As a matter of non-fundamental policy, the Fund complies with the diversification requirements of Rule 2a-7, which are more rigorous.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (1940 Act).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material c hange in these limitations becomes effective.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Investing in Restricted Securities

The Fund may invest in securities subject to restrictions on resale under federal securities laws.

5Table Of Contents

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the commodities restriction, investments in transactions involving futures contracts and options forward currency contracts, swap transactions and other financial contracts that settle by payment in cash are deemed not to be investments in commodities.

In applying the Funds’ concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset backed securities will be classified according to the underlying assets securing such securities. To conform to the current view of the SEC staff that only domestic bank instruments may be excluded from industry concentration limitations, the Funds will not exclude foreign bank instruments from industry concentration tests as long as the policy of the SEC remains in effect. The Funds will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

6Table Of Contents

RULE 12b-1 PLAN

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

7Table Of Contents

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A special meeting of shareholders will be called by the Board upon the written request of shareholders who own at least 10% of the Trust’s outstanding shares of all series entitled to vote.

As of September 7, 2010, the following shareholder owned of record, beneficially, or both, 5% or more of outstanding Shares of the Fund: Pershing LLC, Jersey City, NJ, owned approximately 894,528,440 shares (99.94%).

Shareholders owning 25% or more of outstanding Shares may be in control and be able to affect the outcome of certain matters presented for a vote of shareholders.

8Table Of Contents

Pershing LLC is organized in the state of Delaware as a foreign LLC and is a subsidiary of the Bank of New York Company, organized in the state of New York.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

Who Manages and Provides Services to the Fund?

Board of Trustees

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees). Unless otherwise noted, the address of each person listed is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779. The address of all Independent Trustees listed is 4000 Ericsson Drive, Warrendale, PA 15086-7561; Attention: Mutual Fund Board. As of December 31, 2009, the Trust comprised 39 portfolios, and the Federated Fund Complex consisted of 43 investment companies (comprising 145 portfolios). Unless otherwise noted, each Officer is elected annually. Unless otherwise noted, each Trustee oversees all portfolios in the Federated Fund Complex and serves for an indefinite term.

As of September 7, 2010, the Fund’s Board and Officers as a group owned less than 1% of each Class of the Fund’s outstanding Shares.

qualifications of Independent Trustees

Individual Trustee qualifications are noted in the “Independent Trustees Background and Compensation” chart. In addition, the following characteristics are among those that were considered for each existing Trustee and will be considered for any Nominee Trustee.

• Outstanding skills in disciplines deemed by the Independent Trustees to be particularly relevant to the role of Independent Trustee and to the Federated funds, including legal, accounting, business management, the financial industry generally and the investment industry particularly.
• Desire and availability to serve for a substantial period of time, taking into account the Board’s current mandatory retirement age of 73 years.
• No conflicts which would interfere with qualifying as independent.
• Appropriate interpersonal skills to work effectively with other Independent Trustees.
• Understanding and appreciation of the important role occupied by Independent Trustees in the regulatory structure governing regulated investment companies.
• Diversity of background.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

15Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

16Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

17Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five year and Start of Performance periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	Start of Performance on 2/25/2005
Total Return	N/A	0.02%	1.62%	1.62%
Yield	0.00%	N/A	N/A	N/A
Effective Yield	0.00%	N/A	N/A	N/A
Tax Equivalent Yield	0.00%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

19Table Of Contents

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield, Effective Yield and Tax-Equivalent Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

The tax-equivalent yield of Shares is calculated similarly to the yield, but is adjusted to reflect the taxable yield that Shares would have had to earn to equal the actual yield, assuming the maximum combined federal and state tax rate. To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

20Table Of Contents

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

21Table Of Contents

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fee Waivers and/or Expense Reimbursements1	0.24%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.30%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund's Institutional Capital Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.30% (the “Fee Limit”) through the later of (the “Termination Date”): (a) September 30, 2011; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund's Board of Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

2Table Of Contents

• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

4Table Of Contents

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

5Table Of Contents

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

6Table Of Contents

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

7Table Of Contents

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

8Table Of Contents

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

9Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Capital Shares. All Share classes have different expenses which affect their performance.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

10Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

11Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

12Table Of Contents

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

13Table Of Contents

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

RETIREMENT INVESTMENTS

You may purchase Shares as retirement investments (such as qualified plans and IRAs or transfer or rollover of assets). Call your financial intermediary or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

14Table Of Contents

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds
30 Dan Road

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or

15Table Of Contents

• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

16Table Of Contents

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions

17Table Of Contents

will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional shares. No interest will accrue on amounts represented by uncashed distribution checks. Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

20Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund's financial performance for its past five fiscal years. Some of the information is presented on a per Share basis.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Shares is $500,000, and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and

5Table Of Contents

reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

6Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

7Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases,

8Table Of Contents

the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

9Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

10Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

11Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

15Table Of Contents

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

16Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

17Table Of Contents

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

20Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

2Table Of Contents

• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and

5Table Of Contents

reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

6Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

7Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases,

8Table Of Contents

the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

9Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

10Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

11Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

16Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates.

For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

17Table Of Contents

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the financial performance of the Fund's Institutional Service Shares for the past five fiscal years or since inception, if the life of the Share Class is shorter. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

Information for the fiscal years ended July 31, 2007, 2008, 2009 and 2010, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund's audited financial statements, is included in the Annual Report. Information for the prior year was audited by another independent registered public accounting firm, which issued an unqualified opinion.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

2Table Of Contents

• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Service Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and

5Table Of Contents

reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

6Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

7Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases,

8Table Of Contents

the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

9Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

10Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

11Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

12Table Of Contents

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

13Table Of Contents

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

14Table Of Contents

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600

• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or

15Table Of Contents

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

16Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

17Table Of Contents

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

19Table Of Contents

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

20Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the financial performance of the Fund's Institutional Service Shares for the past five fiscal years or since inception, if the life of the Share Class is shorter.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Trust Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Trust Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Trust Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$81
3 Years	$252
5 Years	$439
10 Years	$978

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

2Table Of Contents

• Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risks.A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Call Risks. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund limits its investments to those that would enable it to qualify as a permissible investment for federally chartered credit unions.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and

5Table Of Contents

reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

6Table Of Contents

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's

7Table Of Contents

return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKs

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Call Risks

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

8Table Of Contents

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if

9Table Of Contents

the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Trust Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

10Table Of Contents

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.25% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Trust Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of

11Table Of Contents

companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees, Service Fees, Account Administration Fees, Recordkeeping Fees and Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

16Table Of Contents

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund. Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by a Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in

18Table Of Contents

cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 LibertyAvenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Government Obligations Fund to Federated Government Obligations Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established four classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares (“Shares”). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury or Government securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Government Mortgage-Backed Securities

Government mortgage-backed securities represent interests in pools of mortgages issued by federal agencies or instrumentalities. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Government mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest form of mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due) payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a fund holding mortgage-backed securities.

For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities.

2Table Of Contents

Conversely, when interest rates rise, the values of mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of mortgage-backed securities, and cause their value to decline more than traditional fixed-income securities.

Generally, mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of a mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (“the spread”). An increase in the spread will cause the price of the mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal. The investment objective may not be changed by the Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification of Investments

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

3Table Of Contents

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending Cash or Securities

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration of Investments

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchasing on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund consider certificate of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the commodities restriction, investments in transactions involving futures contracts and options forward currency contracts, swap transactions and other financial contracts that settle by payment in cash are deemed not to be investments in commodities.

For purposes of the concentration limitation, to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Funds will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Rule 12b-1 Plan (Trust Shares Only)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

In addition, the Plan is integral to the multiple class structure of the Fund, which promotes the sale of Shares by providing a range of options to investors. The Fund’s service providers that receive asset-based fees also benefit from stable or increasing Fund assets.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within

5Table Of Contents

the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

13Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

14Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its dollar-weighted average portfolio maturity and weighted average life, will be posted to the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

15Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

Share performance reflects the effect of non-recurring charges, such as maximum sales charges, which, if excluded, would increase the total return and yield. The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the seven-day period ended July 31, 2010.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to Shareholders of Federated Government Obligations Fund dated July 31, 2010.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

18Table Of Contents

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

19Table Of Contents

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Federated Government Obligations Tax-Managed Fund

A Portfolio of Money Market Obligations Trust

PROSPECTUS

September 30, 2010

INSTITUTIONAL SHARES (TICKER GOTXX)

A money market mutual fund seeking to provide current income consistent with stability of principal and liquidity by investing in a portfolio of short-term U.S. Treasury and government securities that pay interest exempt from state personal income tax.

As with all mutual funds, the Securities and Exchange Commission (SEC) has not approved or disapproved these securities or passed upon the adequacy of this Prospectus. Any representation to the contrary is a criminal offense.

Fund Summary Information

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per Share. The Fund seeks to provide current income consistent with stability of principal and liquidity.

RISK/RETURN SUMMARY: FEES AND EXPENSES

This table describes the fees and expenses that you may pay if you buy and hold Institutional Shares of the Fund.

Shareholder Fees
Fees Paid Directly From Your Investment
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, as applicable)	None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends (and other Distributions) (as a percentage of offering price)	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None
Exchange Fee	None
Annual Fund Operating Expenses
Expenses That You Pay Each Year as a Percentage of the Value of Your Investment
Management Fee	0.20%
Distribution (12b-1) Fee	None
Other Expenses	0.34%
Total Annual Fund Operating Expenses	0.54%
Fee Waivers and/or Expense Reimbursements1	0.34%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.20%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund’s Institutional Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.20% (the “Fee Limit”) through the later of (the “Termination Date”): (a) September 30, 2011; or (b) the date of the Fund’s next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund’s Board of Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund’s Institutional Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund’s Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities that pay interest exempt from state personal income tax.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Bank System and Tennessee Valley Authority. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government. Finally, the Fund may invest in government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities, including the Farm Credit System.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (Rule 2a-7).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Call Risks. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund’s yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

FUND MANAGEMENT

The Fund’s Investment Adviser (“Adviser”) is Federated Investment Management Company.

PURCHASE AND SALE OF FUND SHARES

The required minimum initial investment amount for the Fund’s Institutional Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

TAX INFORMATION

The Fund’s distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests in a portfolio of U.S. Treasury and government securities maturing in 397 days or less that pay interest exempt from state personal income tax. Accordingly, the Fund will not engage in repurchase agreement transactions, or invest in government securities that pay interest subject to state personal income tax, including those issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Assocation, or the Government National Mortgage Association.

The Fund’s Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates; and

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio’s DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

Because the Fund refers to government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States.  Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System and Tennessee Valley Authority in support of such obligations. A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities, including the Farm Credit System.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities (A Fixed-Income Security)

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer.  Callable securities are subject to call risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKS

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money.  Money market funds try to minimize this risk by purchasing higher quality securities.

CALL RISKS

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease.  Conversely, net purchases on days on which short-term yields rise will cause the Fund’s yield to increase.  The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund.  In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments.  However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at  FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 2:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities.  This Prospectus relates only to Institutional Shares. All Share classes have different  expenses which affect their performance.   Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other class.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors  or to individuals, directly or through financial inter­mediaries.  Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts.  Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund.  If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund’s transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

·   through a financial intermediary if you purchased Shares through a financial intermediary; or

·   directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 2:00 p.m. Eastern time and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

If you call the Fund after 2:00 p.m. Eastern time and before the end of regular trading (normally 4:00 p.m. Eastern time) on the NYSE, you will be entitled to that day’s dividend and your redemption proceeds will be sent to you the following business day.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day’s dividend.  If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board’s review of the Fund’s investment advisory contract is available in the Fund’s Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund’s financial performance for its past five fiscal years. Some of the information is presented on a per Share basis.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities that pay interest exempt from state personal income tax.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Bank System and Tennessee Valley Authority. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government. Finally, the Fund may invest in government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities, including the Farm Credit System.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (Rule 2a-7).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Call Risks. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund’s yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests in a portfolio of U.S. Treasury and government securities maturing in 397 days or less that pay interest exempt from state personal income tax. Accordingly, the Fund will not engage in repurchase agreement transactions, or invest in government securities that pay interest subject to state personal income tax, including those issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Assocation, or the Government National Mortgage Association.

The Fund’s Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates; and

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio’s DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

Because the Fund refers to government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States.  Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System and Tennessee Valley Authority in support of such obligations. A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities, including the Farm Credit System.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities (A Fixed-Income Security)

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer.  Callable securities are subject to call risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKS

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money.  Money market funds try to minimize this risk by purchasing higher quality securities.

CALL RISKS

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease.  Conversely, net purchases on days on which short-term yields rise will cause the Fund’s yield to increase.  The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund.  In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments.  However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 2:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities.  This Prospectus relates only to Institutional Service Shares. All Share classes have different  expenses which affect their performance.   Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other class.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial inter­mediaries. Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts.  Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund.  If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary’s procedures for transacting with the Fund.  For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions, dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board’s review of the Fund’s investment advisory contract is available in the Fund’s Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Government Obligations Tax-Managed Fund to Federated Government Obligations Tax-Managed Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established two classes of shares of the Fund, known as Institutional Shares and Institutional Service Shares (“Shares”). This SAI relates to both classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund's Prospectus.  The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective.  The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury or government securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Investment Risks

There are many risk factors which may affect an investment in the Fund.  The Fund's principal risks are described in its Prospectus.  The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

RISKS ASSOCIATED WITH THE INVESTMENT ACTIVITIES OF OTHER ACCOUNTS

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective and Investment Limitations

FUNDAMENTAL INVESTMENT OBJECTIVE

The Fund’s investment objective is to provide current income consistent with stability of principal and liquidity. This investment objective may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

DETERMINING MARKET VALUE OF SECURITIES

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost.  Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity.  If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares.  Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees.  The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries.  Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

VOTING PROXIES ON FUND PORTFOLIO SECURITIES

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio.  The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor.  This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote.  A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes.  Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote.  Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication.  Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted.  If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions.  If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company.  If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did.  Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board.  In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its dollar-weighted average portfolio maturity and weighted average life, will be posted to the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month. The summary portfolio composition information may include the effective average maturity of the Fund's portfolio and percentage breakdowns of the portfolio by credit quality tier, effective maturity range and type of security.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund  may receive nonpublic information about Fund portfolio holdings for purposes relating to their services.  The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies.  Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest.  A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund.  The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders.  In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply.  No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information.  Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security.  Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided.  Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished.  The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

BROKERAGE TRANSACTIONS AND INVESTMENT ALLOCATION

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

ADMINISTRATOR

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10 Years
Institutional Shares:
Total Return	N/A	0.05%	2.83%	2.62%
Yield	0.03%	N/A	N/A	N/A
Effective Yield	0.03%	N/A	N/A	N/A
Institutional Service Shares:
Total Return	N/A	0.01%	2.62%	2.39%
Yield	0.01%	N/A	N/A	N/A
Effective Yield	0.01%	N/A	N/A	N/A

TOTAL RETURN

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

YIELD AND EFFECTIVE YIELD

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Government Obligations Tax-Managed Fund to Federated Government Obligations Tax-Managed Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established two classes of shares of the Fund, known as Institutional Shares and Institutional Service Shares (“Shares”). This SAI relates to Institutional Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund's Prospectus.  The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective.  The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury or government securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Investment Risks

There are many risk factors which may affect an investment in the Fund.  The Fund's principal risks are described in its Prospectus.  The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

RISKS ASSOCIATED WITH THE INVESTMENT ACTIVITIES OF OTHER ACCOUNTS

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective (and Policies) and Investment Limitations

FUNDAMENTAL INVESTMENT OBJECTIVE

The Fund’s investment objective is to provide current income consistent with stability of principal and liquidity. This investment objective may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

DETERMINING MARKET VALUE OF SECURITIES

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost.  Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity.  If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares.  Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees.  The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries.  Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Shareholders owning 25% or more of outstanding Shares may be in control and be able to affect the outcome of certain matters presented for a vote of shareholders.

Bancfirst is organized in the state of Oklahoma.

Tax Information

FEDERAL INCOME TAX

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust's other portfolios will be separate from those realized by the Fund.

Who Manages and Provides Services to the Fund?

BOARD OF TRUSTEES

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees). Unless otherwise noted, the address of each person listed is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222. The address of all Independent Trustees listed is 4000 Ericsson Drive, Warrendale, PA 15086-7561; Attention: Mutual Fund Board. As of December 31, 2009, the Trust comprised 39 portfolios, and the Federated Fund Complex consisted of 43 investment companies (comprising 145 portfolios). Unless otherwise noted, each Officer is elected annually. Unless otherwise noted, each Trustee oversees all portfolios in the Federated Fund Complex and serves for an indefinite term.

As of September 7, 2010, the Fund’s Board and Officers as a group owned less than 1% of the Fund’s outstanding Shares.

QUALIFICATIONS OF INDEPENDENT TRUSTEES

Individual Trustee qualifications are noted in the “Independent Trustees Background and Compensation” chart. In addition, the following characteristics are among those that were considered for each existing Trustee and will be considered for any Nominee Trustee.

·   Outstanding skills in disciplines deemed by the Independent Trustees to be particularly relevant to the role of Independent Trustee and to the Federated funds, including legal, accounting, business management, the financial industry generally and the investment industry particularly.

·   Desire and availability to serve for a substantial period of time, taking into account the Board’s current mandatory retirement age of 73 years.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

VOTING PROXIES ON FUND PORTFOLIO SECURITIES

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio.  The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor.  This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote.  A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes.  Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote.  Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication.  Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted.  If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions.  If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company.  If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did.  Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board.  In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its dollar-weighted average portfolio maturity and weighted average life, will be posted to the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month. The summary portfolio composition information may include the effective average maturity of the Fund's portfolio and percentage breakdowns of the portfolio by credit quality tier, effective maturity range and type of security.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund  may receive nonpublic information about Fund portfolio holdings for purposes relating to their services.  The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies.  Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest.  A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund.  The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders.  In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply.  No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information.  Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security.  Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided.  Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished.  The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

BROKERAGE TRANSACTIONS AND INVESTMENT ALLOCATION

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

ADMINISTRATOR

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the seven-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10  Years
Institutional Shares:
Total Return	NA	0.05%	2.83%	2.62%
Yield	0.03%	NA	NA	NA
Effective Yield	0.03%	NA	NA	NA

TOTAL RETURN

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

YIELD AND EFFECTIVE YIELD

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Example

This Example is intended to help you compare the cost of investing in the Fund’s Class A Shares, Class B Shares, Class C Shares and Class F Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund’s Class A Shares, Class B Shares, Class C Shares and Class F Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. Expenses assum­ing no redemption are also shown. The Example also assumes that your invest­ment has a 5% return each year and that the Fund’s Class A Shares, Class B Shares, Class C Shares and Class F Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Share Class	1 Year	3 Years	5 Years	10 Years
Class A Shares:
Expenses assuming redemption	$127	$397	$686	$1,511

Expenses assuming redemption	$227	$497	$686	$1,511
Expenses assuming no redemption	$127	$397	$686	$1,511

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury and government securities. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities.

Certain of the  government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (Rule 2a-7).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.

·   Issuer Credit Risks. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

·   Counterparty Credit Risks. A party to a transaction involving the Fund may fail to meet its obligations.  This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

·   Call Risks. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.

·   Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund’s portfolio, or if the Fund holds cash, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund’s yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

·   Risks Associated with use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

·   Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

TAX INFORMATION

The Fund’s distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury and government securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury and government securities.

The Fund’s Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

·   current U.S. economic activity and the economic outlook;

·   current short-term interest rates;

·   the Federal Reserve Board’s policies regarding short-term interest rates; and

·   the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio’s DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio’s DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (Adjustable Rate Securities). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund’s ability to invest in Adjustable Rate Securities.

Because the Fund refers to U.S. government investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in U.S. government investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests.  The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities.  However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

Callable Securities

Certain Treasury or government securities in which the Fund invests are callable at the option of the issuer.  Callable securities are subject to call risks.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests.  The Fund may invest in other types of securities or investments as non-principal investments.  Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI.  The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISKS

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securi­ties with longer maturities. Money market funds try to mini­mize this risk by purchasing short-term securities.

ISSUER CREDIT RISKS

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money.  Money market funds try to minimize this risk by purchasing higher quality securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

CALL RISKS

Call risk is the possibility that an issuer may redeem a Treasury or government security before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a Treasury or government security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net pur­chases on days on which short-term yields rise will cause the Fund’s yield to increase. The larger the amount that must be invested or the greater the differ­ence between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund’s Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

CHANGING DISTRIBUTION LEVELS RISK

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund’s ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase Class A Shares or Class B Shares and redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a Regular Business Day). The Fund’s Class C Shares and Class F Shares are not available for direct purchase. They may be acquired exclusively through an exchange from the same share class of another Federated Fund. You may also be able to purchase Class A Shares and Class B Shares and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund’s Board determines to allow Fund Share transactions on such days (a Special Trading Day). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day’s dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated’s website at FederatedInvestors.com. The information set forth in this prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV.  NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open.  The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

SALES CHARGE INFORMATION

The following table summarizes the minimum required investment amount and the maximum sales charge, if any, that you will pay on an investment in the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

	Minimum Initial/Subsequent Investment Amounts1	Maximum Sales Charges
Shares Offered		Front-End Sales Charge	Contingent Deferred Sales Charge2

Class A Shares $1,500/$100 None None

Class B Shares $1,500/$100 None 5.50%

Class C Shares $1,500/$100 None 1.00%

Class F Shares $1,500/$100 None 1.00%

1 The minimum initial and subsequent investment amounts for Individual Retirement Accounts (IRAs) are $250 and $100, respectively. There is no minimum initial or subsequent investment amount required for employer-sponsored retirement plans; however, such accounts remain subject to the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus. The minimum subsequent investment amount for Systematic Investment Programs (SIP) is $50. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund.

            To maximize your return and minimize the sales charges and marketing fees, purchases of Class B Shares are generally limited to $100,000.  Purchases in excess of these limits may be made in Class A Shares.  If your Shares are held on the books of the Fund in the name of a financial intermediary, you may be subject to rules of your financial intermediary that differ from those of the Fund.  See “Purchase Restrictions on Class B Shares” below.  After Class B Shares have been held for eight years from the date of purchase, they will automatically convert to Class A Shares on or about the last day of the following month.  This conversion is a non-taxable event.

2 See “Sales Charge When You Redeem.”

You should consider that Class A Shares do not have front-end or deferred sales charges and that the expense ratio for Class A Shares will be lower than that for Class B Shares. On the other hand, a contingent deferred sales charge (CDSC) is imposed on the redemption of Class B Shares. Thus, Class A Shares will normally be preferable to Class B Shares except when Class B Shares are acquired through an exchange for Class B Shares of another Federated fund. While no CDSC will be charged when Class B Shares of another Federated fund are exchanged for Class B Shares of the Fund, a CDSC may be payable if Class B Shares of another Federated fund are redeemed to purchase Class A Shares of the Fund.

PURCHASE RESTRICTIONS ON CLASS B SHARES

In order to maximize shareholder returns and minimize sales charges and marketing fees, an investor’s purchases of Class B Shares are generally limited to $100,000.  In applying the limit, the dollar amount of the current purchase is added to the product obtained by multiplying the respective maximum public offering price times the number of Class A, Class B, Class C, Class F and Class K shares of any Federated fund currently held in linked Qualifying Accounts.  If the sum of these two amounts would equal or exceed the limit, then the current purchase order will not be processed.  Instead, the Distributor will attempt to contact the investor or the investor’s financial intermediary to offer the opportunity to convert the order to Class A Shares.

If your Shares are held on the books of the Fund in the name of a financial intermediary, you may be subject to rules of your financial intermediary that differ from those of the Fund.

SALES CHARGE WHEN YOU REDEEM

Your redemption proceeds may be reduced by a sales charge, commonly referred to as a contingent deferred sales charge (CDSC).

To keep the sales charge as low as possible, the Fund redeems your Shares in this order:

·   Shares that are not subject to a CDSC; and

·   Shares held the longest (to determine the number of years your Shares have been held, include the time you held shares of other Federated funds that have been exchanged for Shares of this Fund).

The CDSC is then calculated using the Share price at the time of purchase or redemption, whichever is lower.

Class B Shares:
Shares Held Up To:	CDSC
1 Year	5.50%
2 Years	4.75%
3 Years	4.00%
4 Years	3.00%
5 Years	2.00%
6 Years	1.00%
7 Years or More	0.00%

Class C Shares:

You will pay a 1.00% CDSC if you redeem Shares within 12 months of the purchase date.

Class F Shares:
Purchase Amount	Shares Held	CDSC
Up to $2 million	4 years or less	1.00%
$2 million but less than $5 million	2 years or less	0.50%
$5 million or more	1 year or less	0.25%

If your investment qualifies for a reduction or elimination of the CDSC, you or your financial intermediary must notify the Transfer Agent at the time of redemption. If the Transfer Agent is not notified, the CDSC will apply.

Contingent upon notification to the Transfer Agent, you will not be charged a CDSC when redeeming Shares:

·   following the death of the last surviving shareholder on the account or the post-purchase disability of all registered shareholders, as defined in Section 72(m)(7) of the Internal Revenue Code of 1986 (the beneficiary on an account with a Transfer on Death registration is deemed the last surviving shareholder on the account);

·   representing minimum required distributions from an IRA or other retirement plan to a shareholder who has attained the age of 70½;

·   purchased within 120 days of a previous redemption of Shares, to the extent that the value of the Shares purchased was equal to or less than the value of the previous redemption;

·   purchased by Trustees, employees of the Fund, the Adviser, the Distributor and their affiliates, by employees of a financial intermediary that sells Shares according to a sales agreement with the Distributor, by the immediate family members of the above persons and by trusts, pension or profit-sharing plans for the above persons;

·   purchased through a financial intermediary that did not receive an advance commission on the purchase;

·   purchased with reinvested dividends or capital gains;

·   redeemed by the Fund when it closes an account for not meeting the minimum balance requirements;

·   purchased pursuant to the exchange privilege if the Shares were held for the applicable CDSC holding period (the holding period on the Shares purchased in the exchange will include the holding period of the shares sold in the exchange);

Class B Shares Only

·   which are qualifying redemptions of Class B Shares under a Systematic Withdrawal Program.

Class F Shares Only

·   representing a total or partial distribution from a qualified plan, which does not include account transfers, rollovers or redemptions for the purpose of reinvestment. For these purposes, qualified plan does not include an IRA, Keogh Plan or custodial account following retirement.

How is the Fund Sold?

The Fund offers four Share classes: Class A Shares, Class B Shares, Class C Shares and Class F Shares, each representing interests in a single portfolio of securities.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to institutions or to individuals, directly or through financial intermediaries. Under the Distributor’s Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

ADVANCE COMMISSIONS

When a financial intermediary’s customer purchases Shares, the financial intermediary may receive an advance commission as follows:

Class B Shares:
	Advance Commission as a Percentage of Public Offering Price
All Purchase Amounts	Up to 5.50%

Class C Shares:
	Advance Commission as a Percentage of Public Offering Price
All Purchase Amounts	1.00%

Class F Shares:
Purchase Amount	Advance Commission as a Percentage of Public Offering Price
Less than $2 million	1.00%
$2 million but less than $5 million	0.50%
$5 million or greater	0.25%

RULE 12B-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to 0.75% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund’s Class B Shares and Class C Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. In addition, in connection with the sale of Class B Shares and Class C Shares, Federated and its subsidiaries make advance commission payments (effective March 1, 2010, for Class B Shares) to financial intermediaries and in return may receive Rule 12b-1 fees and contingent deferred sales loads for the Class B Shares and Class C Shares. Federated and its subsidiaries may benefit or sustain losses from such arrangements. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different sales charges and marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts.  Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These pay­ments are not reflected in the fees and expenses listed in the fee table section of the Fund’s Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the num­ber or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial interme­diary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial inter­mediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Class A Shares and Class B Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The Fund’s Class C Shares and Class F Shares are not available by direct purchase. They may be acquired exclusively through an exchange from the same share class of another Federated fund. You must meet the minimum initial requirement for purchasing Fund Shares and both accounts must have identical registrations. For information on how to purchase Class C or Class F Shares of the Fund by exchanging shares of the same class of another Federated fund, please see the “How to Redeem and Exchange Shares” section of the other Federated fund’s prospectus.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund.

·   your redemption will be sent to an address other than the address of record;

·   your redemption will be sent to an address of record that was changed within the last 30 days;

·   a redemption is payable to someone other than the shareholder(s) of record; or

·   transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. A notary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

·   an electronic transfer to your account at a financial institution that is an ACH member; or

·   wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

·   to allow your purchase to clear (as discussed below);

·   during periods of market volatility;

·   when a shareholder’s trade activity or amount adversely impacts the Fund’s ability to manage its assets; or

·   during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier’s check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

Any attempt to redeem Shares through checkwriting or debit card before the purchase instrument has cleared will be automatically rejected.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

·   when the NYSE is closed, other than customary weekend and holiday closings;

·   when trading on the NYSE is restricted, as determined by the SEC;

·  

·   in which an emergency exists, as determined by the SEC, so that disposal of the Fund’s investments or determination of its NAV is not reasonably practicable; or

·   in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund into Shares of the same class of another Federated fund. To do this, you must:

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

·   receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase and is a taxable transaction.

The Fund may modify or terminate the exchange privilege at any time.

Possible Sales Charge on Class A Share Exchanges

You may incur a sales charge if you exchange Class A Shares of the Fund for shares of the same class of another Federated fund and you have not previously paid the sales charge applicable to that class of shares. If you acquired your Class A Shares of the Fund through exchange from the same share class of another Federated fund and you paid the sales charge when you purchased your shares of the other fund, you will not be charged a sales charge on any future exchange. However, if your Class A Shares of the Fund were acquired by purchase, rather than through an exchange, you will not have previously paid the sales charge and may have to pay the sales charge when exchanging to another Federated fund.

In determining whether you will incur a sales charge on an exchange to another Federated fund, Shares that are not subject to a sales charge will be deemed to have been exchanged first. You will also not incur a sales charge on an exchange to another Federated fund if your exchange would not have been subject to a sales charge if treated as a purchase of shares of the other Federated fund. For information on the sales charges applicable to purchases of Class A Shares of another Federated fund, please refer to that fund’s Prospectus.

SYSTEMATIC WITHDRAWAL/EXCHANGE PROGRAM

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.  Complete the appropriate section of the New Account Form or an Account Service Options Form or contact your financial intermediary or the Fund. Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

Systematic Withdrawal Program (SWP) on Class B Shares

You will not be charged a CDSC on SWP redemptions if:

·   you redeem 12% or less of your account value in a single year;

·   you reinvest all dividends and capital gains distributions;

·   your account has at least a $10,000 balance when you establish the SWP. (You cannot aggregate multiple Class B Share accounts to meet this minimum balance.); and

·   for all Class B Share accounts established on or after August 2, 2010, the minimum SWP redemption amount is $50 per transaction per fund including transactions that qualify for a CDSC waiver as outlined in this Prospectus.

You will be subject to a CDSC on redemption amounts that exceed the 12% annual limit. In measuring the redemption percentage, your account is valued when you establish the SWP and then annually at calendar year-end. You can redeem monthly, quarterly or semi-annually.

CHECKWRITING (CLASS A SHARES ONLY)

You may request checks to redeem your Fund Shares. Your account will continue to receive the daily dividend declared on the Shares being redeemed until the check is presented for payment.

DEBIT CARD (CLASS A SHARES ONLY)

You may request a debit card account that allows you to redeem Shares. There is an annual fee for this service that the Fund will automatically deduct from your account.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund’s distributions, including the percentage of the Fund’s distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated’s website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $1,500 or in the case of IRAs $250. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund’s investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders.  For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund’s Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund’s Shares.  Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund’s portfolio and its performance.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys’ fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund’s financial performance for its past five fiscal years. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

This information has been audited by Ernst & Young LLP, an independent registered public accounting firm, whose report, along with the Fund’s audited financial statements, is included in the Annual Report.

Appendix A: Hypothetical Investment and Expense Information

The following charts provide additional hypothetical information about the effect of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s assumed returns over a 10-year period. Each chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund’s annual expense ratio stays the same throughout the 10-year period (except Class B Shares, which convert to Class A Shares after you have held them for eight years) and that all dividends and distributions are reinvested. The annual expense ratios used in each chart are the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Liberty U.S. Government Money Market Trust to Federated Liberty U.S. Government Money Market Trust on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities. The Fund, which was established on August 30, 1979, was reorganized as a portfolio of the Trust on July 30, 1999.

The Board of Trustees (Board) has established four classes of shares of the Fund, known as Class A Shares, Class B Shares, Class C Shares and Class F Shares (Shares). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (Adviser).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund's Prospectus.  The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective.  The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury or Government securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Government Mortgage-Backed Securities

Government mortgage-backed securities represent interests in pools of mortgages issued by federal agencies or instrumentalities. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Government mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest form of mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in securities of other investment companies, including the securities of affiliated money market funds, as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

Credit Enhancement

The Fund may invest in securities with credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

The Fund will only invest in securities with credit enhancement if the entity providing the credit enhancement is the U.S. government or an agency or instrumentality of the U.S. government.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to security’s holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Investment Risks

There are many risk factors which may affect an investment in the Fund.  The Fund's principal risks are described in its Prospectus.  The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

LEVERAGE RISKS

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due) payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a fund holding mortgage-backed securities.

For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities.

Conversely, when interest rates rise, the values of mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of mortgage-backed securities, and cause their value to decline more than traditional fixed-income securities.

Generally, mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of a mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (“the spread”). An increase in the spread will cause the price of the mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH THE INVESTMENT ACTIVITIES OF OTHER ACCOUNTS

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

RISKS ASSOCIATED WITH TEMPORARY LIQUIDITY GUARANTEE PROGRAM

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s fundamental investment objective is stability of principal and current income consistent with stability of principal. The investment objective may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments are not deemed to constitute an industry.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940, as amended (1940 Act).

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Pledging Assets

The Fund will not mortgage, pledge, or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in the value or net assets will not result in a violation of such limitation.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

DETERMINING MARKET VALUE OF SECURITIES

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost.  Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity.  If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

RULE 12b-1 PLAN (CLASS B SHARES AND CLASS C SHARES)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares.  The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

In addition, the Plan is integral to the multiple class structure of the Fund, which promotes the sale of Shares by providing a range of options to investors. The Fund's service providers that receive asset-based fees also benefit from stable or increasing Fund assets.

For some classes of Shares, the maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

In addition, in connection with the sale of Class B Shares and Class C Shares, Federated and its subsidiaries make advance commission payments (effective March 1, 2010, for Class B Shares) to financial intermediaries and in return may receive Rule 12b-1 fees and contingent deferred sales loads from the Class B Shares and Class C Shares. Federated and its subsidiaries may benefit or sustain losses from such arrangements.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares.  Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees.  The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries.  Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

UNDERWRITING COMMISSIONS

The following chart reflects the total front-end sales charges and contingent deferred sales charges paid in connection with the sale of Class A Shares, Class B Shares, Class C Shares and Class F Shares and the amount retained by the Distributor for the last three fiscal years ended July 31:

	2010		2009		2008
	Total Sales Charges	Amount Retained	Total Sales Charges	Amount Retained	Total Sales Charges	Amount Retained
Class A Shares	$0	$0	$0	$0	$0	$0
Class B Shares	83,333	0	216,960	0	0	0
Class C Shares	1,193	1,193	8,351	8,351	0	0
Class F Shares	217	217	2,256	2,256	0	0

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser.  The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

VOTING PROXIES ON FUND PORTFOLIO SECURITIES

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio.  The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor.  This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote.  A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes.  Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote.  Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication.  Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted.  If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions.  If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company.  If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did.  Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board.  In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its dollar-weighted average portfolio maturity and weighted average life, will be posted to the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month. The summary portfolio composition information may include the effective average maturity of the Fund's portfolio and percentage breakdowns of the portfolio by credit quality tier, effective maturity range and type of security.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund  may receive nonpublic information about Fund portfolio holdings for purposes relating to their services.  The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies.  Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest.  A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund.  The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders.  In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply.  No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information.  Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security.  Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided.  Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished.  The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

BROKERAGE TRANSACTIONS AND INVESTMENT ALLOCATION

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

ADMINISTRATOR

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

CUSTODIAN

State Street Bank and Trust Company, Boston, Massachusetts, is custodian for the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

State Street Bank and Trust Company, the Fund’s registered transfer agent, maintains all necessary shareholder records.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The independent registered public accounting firm for the Fund, Ernst & Young LLP, conducts its audits in accordance with the standards of the Public Company Accounting Oversight Board (United States), which require it to plan and perform its audits to provide reasonable assurance about whether the Fund’s financial statements and financial highlights are free of material misstatement.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year or Start of Performance periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

TOTAL RETURN

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

YIELD AND EFFECTIVE YIELD

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the alternative minimum tax for individuals and corporations (AMT). The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

3Table Of Contents

• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Capital Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be tax-exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Any Fund distributions of capital gains are taxable at applicable capital gains rates. The Fund is generally not a suitable investment for retirement accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

5Table Of Contents

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

The Fund's investment adviser (“Adviser”) targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others) current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve's monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns. In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of nationally recognized statistical rating organizations (NRSROs).

Because the Fund refers to municipal investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. This policy may not be changed without shareholder approval. The Adviser may invest in securities subject to the federal AMT for individuals and corporations in an attempt to enhance yield and provide diversification.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of

6Table Of Contents

calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent to fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand

7Table Of Contents

instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the

8Table Of Contents

company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. The Fund may invest in bonds subject to AMT.

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand

9Table Of Contents

Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or sub-categories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and

10Table Of Contents

higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

11Table Of Contents

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests. Income from the Fund also may be subject to the AMT.

12Table Of Contents

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

13Table Of Contents

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Institutional Capital Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Capital Shares.

14Table Of Contents

All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. The Fund may not be a suitable investment for retirement plans. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

16Table Of Contents

THROUGH A FINANCIAL INTERMEDIARY

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);

20Table Of Contents

• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

21Table Of Contents

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

24Table Of Contents

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the alternative minimum tax for individuals and corporations (AMT). The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Fund Management

The Fund's Investment Adviser (“Adviser”) is Federated Investment Management Company.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be tax-exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Any Fund distributions of capital gains are taxable at applicable capital gains rates. The Fund is generally not a suitable investment for retirement accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular

5Table Of Contents

income tax. Interest from the Fund's investments may be subject to the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

The Fund's investment adviser (“Adviser”) targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others) current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve's monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns. In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of nationally recognized statistical rating organizations (NRSROs).

Because the Fund refers to municipal investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. This policy may not be changed without shareholder approval. The Adviser may invest in securities subject to the federal AMT for individuals and corporations in an attempt to enhance yield and provide diversification.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such

6Table Of Contents

temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent to fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects

7Table Of Contents

prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. The Fund may invest in bonds subject to AMT.

8Table Of Contents

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or sub-categories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest

9Table Of Contents

short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

10Table Of Contents

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

11Table Of Contents

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests. Income from the Fund also may be subject to the AMT.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

12Table Of Contents

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Institutional Capital Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. The Fund may not be a suitable investment for retirement plans. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);

20Table Of Contents

• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

21Table Of Contents

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

24Table Of Contents

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Funds' Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the alternative minimum tax for individuals and corporations (AMT). The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

3Table Of Contents

• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Service Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be tax-exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Any Fund distributions of capital gains are taxable at applicable capital gains rates. The Fund is generally not a suitable investment for retirement accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

5Table Of Contents

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. Interest from the Fund's investments may be subject to the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

The Fund's investment adviser (“Adviser”) targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others) current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve's monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns. In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of nationally recognized statistical rating organizations (NRSROs).

Because the Fund refers to municipal investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. This policy may not be changed without shareholder approval. The Adviser may invest in securities subject to the federal AMT for individuals and corporations in an attempt to enhance yield and provide diversification.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of

6Table Of Contents

calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent to fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand

7Table Of Contents

instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the

8Table Of Contents

company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. The Fund may invest in bonds subject to AMT.

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand

9Table Of Contents

Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or sub-categories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and

10Table Of Contents

higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

11Table Of Contents

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests. Income from the Fund also may be subject to the AMT.

12Table Of Contents

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

13Table Of Contents

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Institutional Capital Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. The

14Table Of Contents

additional classes of Shares, which are offered by separate prospectus, may be preferrable for certain shareholders. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. The Fund may not be a suitable investment for retirement plans. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

20Table Of Contents

• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

21Table Of Contents

Share Certificates

For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund was reorganized as a portfolio of the Trust on October 27, 1999. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Institutional Capital Shares (“Shares”). This SAI relates to Institutional Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”). Effective June 30, 2010, the Fund changed its name from “Municipal Obligations Fund” to “Federated Municipal Obligations Fund.”

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund may invest:

Municipal Leases (A Type of Tax-Exempt, Fixed-Income Security)

Municipalities may enter into leases for equipment or facilities. In order to comply with state public financing laws, these leases are typically subject to annual appropriation. In other words, a municipality may end a lease, without penalty, by not providing for the lease payments in its annual budget. After the lease ends, the lessor can resell the equipment or facility but may lose money on the sale. The Fund may invest in securities supported by pools of municipal leases. The most common type of lease-backed securities are certificates of participation (COPs). However, the Fund may also invest directly in individual leases.

Callable Securities (A Type of Tax-Exempt, Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Certain callable securities invested in by the Fund also may be callable by parties other than the issuer. Callable securities are subject to call risks.

Zero-Coupon Securities (A Type of Tax-Exempt, Fixed-Income Security)

Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero-coupon security.

There are many forms of zero-coupon securities. Some are issued at a discount and are referred to as zero-coupon or capital-appreciation bonds. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

1Table Of Contents

Tax Increment Financing Bonds (A Type of Tax-Exempt, Fixed-Income Security)

Tax increment financing (TIF) bonds are payable from increases in taxes or other revenues attributable to projects within the TIF district. For example, a municipality may issue TIF bonds to redevelop a commercial area. The TIF bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could fail to pay principal or interest if merchants’ sales, and related tax collections, failed to increase as anticipated.

Municipal Mortgage-Backed Securities (A Type of Tax-Exempt, Fixed-Income Security)

Municipal mortgage-backed securities are special revenue bonds the proceeds of which may be used to provide mortgage loans for single family homes or to finance multifamily housing. Municipal mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable rates. Interests in pools of adjustable-rate mortgages are known as ARMs. Municipal mortgage-backed securities generally have fixed interest rates.

Municipal mortgage-backed securities come in a variety of forms. The simplest forms of municipal mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other municipal mortgage-backed securities may have more complicated financial structures.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

2Table Of Contents

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. These transactions may create leverage risks.

Temporary Investments

The Fund may make temporary investments in taxable, fixed-income securities and the following other taxable securities:

Treasury Securities (A Type of Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Type of Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

3Table Of Contents

Bank Instruments (A Type of Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Corporate Debt Securities (A Type of Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default. The short maturity of commercial paper generally reduces both the market and credit risks as compared to other debt securities of the same issuer.

Repurchase Agreements (A Type of Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks. In addition to taxable repurchase agreements, the Fund also may invest in municipal repurchase agreements as a non-principal investment.

Reverse Repurchase Agreements (A Type of Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase. In addition to taxable reverse repurchase agreements, the Fund also may invest in municipal reverse repurchase agreements as a non-principal investment.

INVESTMENT RATINGS

The two highest rating categories of a nationally recognized statistical rating organization (NRSRO) are determined without regard for sub-categories and gradations. For example, securities rated SP-1+, SP-1 or SP-2 by Standard & Poor’s (“S&P”), MIG-1 or MIG-2 by Moody’s Investors Service (“Moody’s”) or F-1+, F-1 or F-2 by Fitch Ratings (“Fitch”) are all considered rated in one of the two highest short-term rating categories. The Fund will follow applicable regulations in determining whether a security rated by more than one NRSRO can be treated as being in the highest, or one of the two highest short-term rating categories; currently, such securities must be rated by two rating services in one of their two highest rating categories. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

4Table Of Contents

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective (and Policies) and Investment Limitations

The investment objective of the Fund is to provide current income exempt from all federal regular income tax consistent with stability of principal.

As a matter of investment policy which cannot be changed without shareholder approval, at least 80% of the Fund’s income will be exempt from federal regular income tax (federal regular income tax does not include the federal alternative minimum tax for individuals and corporations). The Fund will invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax.

The investment objective may be changed by the Fund’s Board without shareholder approval. The investment policy may not be changed by the Fund’s Board without shareholder approval.

Investment Limitations

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

5Table Of Contents

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

6Table Of Contents

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

7Table Of Contents

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

The Committee will consider candidates recommended by shareholders, Independent Trustees, officers or employees of any of the Fund’s agents or service providers and counsel to the Fund. Any shareholder who desires to have an individual considered for nomination by the Committee must submit a recommendation in writing to the Secretary of the Fund, at the Fund’s address appearing on the back cover of this SAI. The recommendation should include the name and address of both the shareholder and the candidate and detailed information concerning the candidate’s qualifications and experience. In identifying and evaluating candidates for consideration, the Committee shall consider such factors as it deems appropriate. Those factors will ordinarily include: integrity, intelligence, collegiality, judgment, diversity, skill, business and other experience, qualification as an “Independent Trustee,” the existence of material relationships which may create the appearance of a lack of independence, financial or accounting knowledge and experience and dedication and willingness to devote the time and attention necessary to fulfill Board responsibilities.

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

On behalf of the Board, the Audit Committee plays a key role overseeing the Fund’s financial reporting and valuation risks. The Audit Committee meets regularly with the Fund’s Principal Financial Officer and outside auditors, as well as with Federated’s Chief Audit Executive to discuss financial reporting and audit issues, including risks relating to financial controls.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

15Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

16Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

Portfolio Holdings Information

Information concerning the Fund’s portfolio holdings is available in the “Products” section of Federated’s website at FederatedInvestors.com. A complete listing of the Fund’s portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month. In order to comply with amendments to Rule 2a-7, effective October 7, 2010, information concerning the Fund’s portfolio holdings, as well as its dollar-weighted average portfolio maturity and weighted average life, will be posted to the website five business days after the end of the month and remain posted on the website for six months thereafter. Summary portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month. The summary portfolio composition information may include identification of the Fund’s top 10 credit/obligor exposures, effective average maturity of the Fund’s portfolio and percentage breakdown of the portfolio by credit quality tier, effective maturity range and type of security.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

17Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

Fees are allocated among classes based on their pro rata share of Fund assets, except for shareholder services fees, which are borne only by the applicable class of Shares.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10 Years
Institutional Shares:
Total Return	N/A	0.27%	2.25%	2.09%
Yield	0.23%	N/A	N/A	N/A
Effective Yield	0.23%	N/A	N/A	N/A
Tax-Equivalent Yield	0.35%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

19Table Of Contents

Yield, Effective Yield and Tax-Equivalent Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

The tax-equivalent yield of Shares is calculated similarly to the yield, but is adjusted to reflect the taxable yield that Shares would have had to earn to equal the actual yield, assuming the maximum combined federal and state tax rate. To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to shareholders of Federated Municipal Obligations Fund dated July 31, 2010.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

20Table Of Contents

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund was reorganized as a portfolio of the Trust on October 27, 1999. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Institutional Capital Shares (“Shares”). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”). Effective June 30, 2010, the Fund changed its name from “Municipal Obligations Fund” to “Federated Municipal Obligations Fund.”

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund may invest:

Municipal Leases (A Type of Tax-Exempt, Fixed-Income Security)

Municipalities may enter into leases for equipment or facilities. In order to comply with state public financing laws, these leases are typically subject to annual appropriation. In other words, a municipality may end a lease, without penalty, by not providing for the lease payments in its annual budget. After the lease ends, the lessor can resell the equipment or facility but may lose money on the sale. The Fund may invest in securities supported by pools of municipal leases. The most common type of lease-backed securities are certificates of participation (COPs). However, the Fund may also invest directly in individual leases.

Callable Securities (A Type of Tax-Exempt, Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Certain callable securities invested in by the Fund also may be callable by parties other than the issuer. Callable securities are subject to call risks.

Zero-Coupon Securities (A Type of Tax-Exempt, Fixed-Income Security)

Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero-coupon security.

There are many forms of zero-coupon securities. Some are issued at a discount and are referred to as zero-coupon or capital-appreciation bonds. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

1Table Of Contents

Tax Increment Financing Bonds (A Type of Tax-Exempt, Fixed-Income Security)

Tax increment financing (TIF) bonds are payable from increases in taxes or other revenues attributable to projects within the TIF district. For example, a municipality may issue TIF bonds to redevelop a commercial area. The TIF bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could fail to pay principal or interest if merchants’ sales, and related tax collections, failed to increase as anticipated.

Municipal Mortgage-Backed Securities (A Type of Tax-Exempt, Fixed-Income Security)

Municipal mortgage-backed securities are special revenue bonds the proceeds of which may be used to provide mortgage loans for single family homes or to finance multifamily housing. Municipal mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable rates. Interests in pools of adjustable-rate mortgages are known as ARMs. Municipal mortgage-backed securities generally have fixed interest rates.

Municipal mortgage-backed securities come in a variety of forms. The simplest forms of municipal mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other municipal mortgage-backed securities may have more complicated financial structures.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

2Table Of Contents

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. These transactions may create leverage risks.

Temporary Investments

The Fund may make temporary investments in taxable, fixed-income securities and the following other taxable securities:

Treasury Securities (A Type of Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Type of Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Bank Instruments (A Type of Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Corporate Debt Securities (A Type of Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default. The short maturity of commercial paper generally reduces both the market and credit risks as compared to other debt securities of the same issuer.

Repurchase Agreements (A Type of Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks. In addition to taxable repurchase agreements, the Fund also may invest in municipal repurchase agreements as a non-principal investment.

Reverse Repurchase Agreements (A Type of Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase. In addition to taxable reverse repurchase agreements, the Fund also may invest in municipal reverse repurchase agreements as a non-principal investment.

INVESTMENT RATINGS

The two highest rating categories of a nationally recognized statistical rating organization (NRSRO) are determined without regard for sub-categories and gradations. For example, securities rated SP-1+, SP-1 or SP-2 by Standard & Poor’s (“S&P”), MIG-1 or MIG-2 by Moody’s Investors Service (“Moody’s”) or F-1+, F-1 or F-2 by Fitch Ratings (“Fitch”) are all considered rated in one of the two highest short-term rating categories. The Fund will follow applicable regulations in determining whether a security rated by more than one NRSRO can be treated as being in the highest, or one of the two highest short-term rating categories; currently, such securities must be rated by two rating services in one of their two highest rating categories. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

4Table Of Contents

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective (and Policies) and Investment Limitations

The investment objective of the Fund is to provide current income exempt from all federal regular income tax consistent with stability of principal.

As a matter of investment policy which cannot be changed without shareholder approval, at least 80% of the Fund’s income will be exempt from federal regular income tax (federal regular income tax does not include the federal alternative minimum tax for individuals and corporations). The Fund will invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax.

The investment objective may be changed by the Fund’s Board without shareholder approval. The investment policy may not be changed by the Fund’s Board without shareholder approval.

Investment Limitations

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

5Table Of Contents

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

6Table Of Contents

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

7Table Of Contents

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

8Table Of Contents

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

15Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

16Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

17Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield, Effective Yield and Tax-Equivalent Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

The tax-equivalent yield of Shares is calculated similarly to the yield, but is adjusted to reflect the taxable yield that Shares would have had to earn to equal the actual yield, assuming the maximum combined federal and state tax rate. To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to shareholders of Federated Municipal Obligations Fund dated July 31, 2010.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

20Table Of Contents

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

21Table Of Contents

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Capital Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form.

20Table Of Contents

• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

21Table Of Contents

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

24Table Of Contents

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund

24Table Of Contents

shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the financial performance of the Fund's Institutional Shares for the past five fiscal years or since inception, if the life of the Share Class is shorter. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

Information for the fiscal years ended July 31, 2007, 2008, 2009 and 2010, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund's audited financial statements, is included in the Annual Report. Information for the prior year was audited by another independent registered public accounting firm, which issued an unqualified opinion.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services.

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund

24Table Of Contents

shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the financial performance of the Fund's Institutional Service Shares for the past five fiscal years or since inception, if the life of the Share Class is shorter. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

Information for the fiscal years ended July 31, 2007, 2008, 2009 and 2010, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund's audited financial statements, is included in the Annual Report.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Trust may offer separate series of shares representing interests in separate portfolios of securities. The Fund changed its name from Prime Cash Obligations Fund to Federated Prime Cash Obligations Fund on June 30, 2010.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Capital Shares and Institutional Service Shares (“Shares”). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

1Table Of Contents

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

2Table Of Contents

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The highest rating category of a nationally recognized statistical rating organization (NRSRO) is determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (S&P), Prime-1 by Moody’s Investors Service (“Moody’s”), F-1+ or F-1 by Fitch Ratings (“Fitch”) or R-1 (high), R-1 (middle) or R-1 (low) by Dominion Bond Rating Service (DBRS) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal and liquidity. The investment objective may be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification of Investments

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

4Table Of Contents

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending Cash or Securities

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration of Investments

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the Investment Company Act of 1940 ( “ 1940 Act ” ). The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchasing on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector, and the financial services sector to include banks, broker-dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset-backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third-party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

5Table Of Contents

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

6Table Of Contents

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

Who Manages and Provides Services to the Fund?

Board of Trustees

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees).

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

14Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

15Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website.

This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

16Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 — Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 — Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns “dual” ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

19Table Of Contents

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 — A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 — A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA — An obligation rated “AAA” has the highest assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA — An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A — An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (“MOODY’S”) Short-Term Municipal Obligations Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 — This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2 — This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 — Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 — Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa — Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa — Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

20Table Of Contents

A — Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR — Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) — The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) — The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) — The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Ratings Short-Term Debt Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 — Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fitch Ratings Long-Term Debt Rating Definitions

AAA — Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA — Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A — High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB — Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Fitch Ratings Commercial Paper Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

DBRS Short-Term Debt And Commercial Paper Rating Definitions

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high) — Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle) — Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

21Table Of Contents

R-1 (low) — Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low) — Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS Long-Term Debt Rating Definitions

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

“AAA” — Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA” — Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A” — Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

“High” or “low” — grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and “low” grades are not used for the AAA category.

A.M. Best Long-Term Debt Ratings

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due. These ratings are assigned to debt and preferred stock issues.

aaa — Exceptional. Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa — Very Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a — Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category. A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change. Ratings prefixed with an (“i”) denote indicative ratings. Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. Best Short-Term Debt Ratings

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

22Table Of Contents

AMB-1+ — Strongest. Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1 — Outstanding. Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2 — Satisfactory. Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3 — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. Best Rating Outlook

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months. Public Data Ratings are not assigned an Outlook. Ratings Outlooks are as follows:

Positive — Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

Negative — Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable — Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

3Table Of Contents

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

The following provides general information on the types of securities in which the Fund principally invests. The Fund may invest in other types of securities as a non-principal investment as described in the Fund's Statement of Additional Information (SAI).

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

7Table Of Contents

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

8Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the

9Table Of Contents

underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Service Shares and Institutional Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Capital Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Record Keeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

21Table Of Contents

Share Certificates

The Fund no longer issues share certificates.

For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

24Table Of Contents

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Fund Management

The Fund's Investment Adviser (“Adviser”) is Federated Investment Management Company.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open.

Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Service Shares and Institutional Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

22Table Of Contents

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are

24Table Of Contents

generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$56
3 Years	$176
5 Years	$307
10 Years	$689

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

The following provides general information on the types of securities in which the Fund principally invests. The Fund may invest in other types of securities as a non-principal investment as described in the Fund's Statement of Additional Information (SAI).

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

7Table Of Contents

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

8Table Of Contents

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the

9Table Of Contents

underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Service Shares and Institutional Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Record Keeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

22Table Of Contents

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are

24Table Of Contents

generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Prime Management Obligations Fund to Federated Prime Management Obligations Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (Board) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Institutional Capital Shares (Shares). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (Adviser).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

1Table Of Contents

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

2Table Of Contents

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. The Fund has no present intention to engage in securities lending.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

3Table Of Contents

The highest rating category of a nationally recognized statistical rating organization (NRSRO) is determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (S&P), Prime-1 by Moody’s Investors Service (“Moody’s”), F-1+ or F-1 by Fitch Ratings (“Fitch”) or R-1 (high), R-1 (middle) or R-1 (low) by Dominion Bond Rating Service (DBRS) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The investment objective of the Fund is to provide current income consistent with stability of principal. The investment objective may not be changed by the Fund’s Board without shareholder approval.

Investment Limitations

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

4Table Of Contents

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (1940 Act).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans except it may make loans to affiliated investment companies in accordance with SEC exemptive relief. This restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements and/or derivative contracts, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

5Table Of Contents

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector, and the financial services sector to include banks, broker-dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset-backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within

6Table Of Contents

the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

8Table Of Contents

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

Who Manages and Provides Services to the Fund?

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

On behalf of the Board, the Audit Committee plays a key role overseeing the Fund’s financial reporting and valuation risks. The Audit Committee meets regularly with the Fund’s Principal Financial Officer and outside auditors, as well as with Federated’s Chief Audit Executive to discuss financial reporting and audit issues, including risks relating to financial controls.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

15Table Of Contents

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible

17Table Of Contents

that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

On July 31, 2010, the Fund owned securities of the following regular broker/dealers: BNP Paribas, $100,000,000; Bank of America, $25,000,000; Citigroup, $130,000,000; Barclays Bank, $85,000,000; Wells Fargo, $80,000,000; RBC Capital Markets, $50,500,000.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

18Table Of Contents

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year or Start of Performance periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	Start of Performance on 8/11/2004
Institutional Shares:
Total Return	N/A	0.24%	3.14%	3.03%
Yield	0.29 %	N/A	N/A	N/A
Effective Yield	0.29%	N/A	N/A	N/A

	7-Day Period	1 Year	5 Years	Start of Performance on 1/18/2005
Institutional Service Shares:
Total Return	N/A	0.04%	2.89%	2.87%
Yield	0.04%	N/A	N/A	N/A
Effective Yield	0.04%	N/A	N/A	N/A

	7-Day Period	1 Year	5 Years	Start of Performance on 1/18/2005
Institutional Capital Shares:

Yield	0.20%	N/A	N/A	N/A
Effective Yield	0.20%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 — Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 — Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns “dual” ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 — A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 — A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA — An obligation rated “AAA” has the highest assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA — An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A — An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (“MOODY’S”) Short-Term Municipal Obligations Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 — This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2 — This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

20Table Of Contents

Moody’s Commercial Paper (CP) Ratings

Prime-1 — Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 — Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa — Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa — Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A — Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR — Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) — The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) — The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) — The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Ratings Short-Term Debt Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 — Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fitch Ratings Long-Term Debt Rating Definitions

AAA — Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA — Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A — High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB — Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

DBRS Short-Term Debt And Commercial Paper Rating Definitions

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high) — Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle) — Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

R-1 (low) — Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low) — Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS Long-Term Debt Rating Definitions

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

“AAA” — Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA” — Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A” — Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

22Table Of Contents

“High” or “low” — grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and “low” grades are not used for the AAA category.

A.M. Best Long-Term Debt Ratings

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due. These ratings are assigned to debt and preferred stock issues.

aaa — Exceptional. Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa — Very Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a — Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category. A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change. Ratings prefixed with an (“i”) denote indicative ratings. Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. Best Short-Term Debt Ratings

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

AMB-1+ — Strongest. Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1 — Outstanding. Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2 — Satisfactory. Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3 — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. Best Rating Outlook

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months. Public Data Ratings are not assigned an Outlook. Ratings Outlooks are as follows:

Positive — Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

Negative — Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable — Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's investment adviser (“Adviser”) actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

22Table Of Contents

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are

24Table Of Contents

generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's investment adviser (“Adviser”) actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Funds and their affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

22Table Of Contents

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund's portfolio holdings is available in the “Products” section of Federated's website at FederatedInvestors.com. A complete listing of the Fund's portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month.

Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC's website at www.sec.gov.

In addition, from time to time (for example, during periods of unusual market conditions), additional information regarding the Fund's portfolio holdings and/or composition may be posted to Federated's website. If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are

24Table Of Contents

generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Trust Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Trust Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Trust Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$81
3 Years	$252
5 Years	$439
10 Years	$978

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's investment adviser (“Adviser”) actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

10Table Of Contents

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does

11Table Of Contents

not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

12Table Of Contents

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

13Table Of Contents

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Trust Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

14Table Of Contents

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.25% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Trust Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees and Networking Fees on that same account.

15Table Of Contents

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

16Table Of Contents

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

21Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.

Your account value must meet the minimum initial investment amount at the time the program is established. This program may reduce, and eventually deplete, your account. Payments should not be considered yield or income.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by a Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions

22Table Of Contents

will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of realizing a capital gain.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the

23Table Of Contents

Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

25Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund's financial performance for its past five fiscal years. Some of the information is presented on a per Share basis. Total returns represent the rate an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of any dividends and capital gains.

Information for the four fiscal years ended July 31, 2010, 2009, 2008 and 2007, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund's audited financial statements, is included in the Annual Report. Information for the prior year was audited by another independent registered public accounting firm, which issued an unqualified opinion.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Prime Obligations Fund to Federated Prime Obligations Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Trust Shares (“Shares”). This SAI relates to Institutional Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

2Table Of Contents

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. The Fund has no present intention to engage in securities lending.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The highest rating category of a nationally recognized statistical rating organization (NRSRO) is determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (S&P), Prime-1 by Moody’s Investors Service (“Moody’s”), F-1+ or F-1 by Fitch Ratings (“Fitch”) or R-1 (high), R-1 (middle) or R-1 (low) by Dominion Bond Rating Service (DBRS) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

3Table Of Contents

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal. The investment objective may not be changed by the Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification of Investments

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

4Table Of Contents

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending Cash or Securities

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration of Investments

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchasing on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector, and the financial services sector to include banks, broker-dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset-backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third-party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

6Table Of Contents

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A special meeting of shareholders will be called by the Board upon the written request of shareholders who own at least 10% of the Trust’s outstanding shares of all series entitled to vote.

7Table Of Contents

As of September 7, 2010, the following shareholders owned of record, beneficially, or both, 5% or more of outstanding Institutional Shares: JP Morgan Clearing Corp., Brooklyn, NY, owned approximately 2,300,000,000 Shares (5.87%); BNP Baribas, Luxembourg, owned approximately 4,103,866,616 Shares (10.48%); Hare & Co., East Syracuse, NY, owned approximately 6,888,992,627 Shares (17.59%).

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

Who Manages and Provides Services to the Fund?

Board of Trustees

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees). Unless otherwise noted, the address of each person listed is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779. The address of all Independent Trustees listed is 4000 Ericsson Drive, Warrendale, PA 15086-7561; Attention: Mutual Fund Board. As of December 31, 2009, the Trust comprised 39 portfolios, and the Federated Fund Complex consisted of 43 investment companies (comprising 145 portfolios). Unless otherwise noted, each Officer is elected annually. Unless otherwise noted, each Trustee oversees all portfolios in the Federated Fund Complex and serves for an indefinite term.

As of September 7, 2010, the Fund’s Board and Officers as a group owned less than 1% of the Fund’s outstanding Institutional Shares.

qualifications of Independent Trustees

Individual Trustee qualifications are noted in the “Independent Trustees Background and Compensation” chart. In addition, the following characteristics are among those that were considered for each existing Trustee and will be considered for any Nominee Trustee.

• Outstanding skills in disciplines deemed by the Independent Trustees to be particularly relevant to the role of Independent Trustee and to the Federated funds, including legal, accounting, business management, the financial industry generally and the investment industry particularly.
• Desire and availability to serve for a substantial period of time, taking into account the Board’s current mandatory retirement age of 73 years.
• No conflicts which would interfere with qualifying as independent.
• Appropriate interpersonal skills to work effectively with other Independent Trustees.
• Understanding and appreciation of the important role occupied by Independent Trustees in the regulatory structure governing regulated investment companies.

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

14Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

15Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

16Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies and to commodities exchange clearing corporations in connection with qualifying the Fund’s Shares for use as margin collateral. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

On July 31, 2010, the Fund owned securities of the following regular broker/dealers: BNP Paribas $1,177,500,000; Bank of America $1,475,500,000; Citigroup $1,302,900,000; Barclays Bank $2,057,500,000; Deutsche Bank $2,077,195,000; JPMorgan Chase $1,406,500,000.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

17Table Of Contents

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10 Years
Institutional Shares:
Total Return	N/A	0.17%	3.06%	2.79%
Yield	0.24%	N/A	N/A	N/A
Effective Yield	0.25%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

18Table Of Contents

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Financial Information

The Financial Statements for the Fund for the fiscal year ended July 31, 2010, are incorporated herein by reference to the Annual Report to shareholders of Federated Prime Obligations Fund dated July 31, 2010.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 — Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 — Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns “dual” ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 — A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 — A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA — An obligation rated “AAA” has the highest assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA — An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

19Table Of Contents

A — An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (“MOODY’S”) Short-Term Municipal Obligations Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 — This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2 — This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 — Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 — Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa — Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa — Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A — Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR — Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) — The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) — The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) — The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Ratings Short-Term Debt Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

20Table Of Contents

F-3 — Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fitch Ratings Long-Term Debt Rating Definitions

AAA — Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA — Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A — High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB — Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Fitch Ratings Commercial Paper Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

DBRS Short-Term Debt And Commercial Paper Rating Definitions

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high) — Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle) — Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

R-1 (low) — Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low) — Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS Long-Term Debt Rating Definitions

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

21Table Of Contents

“AAA” — Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA” — Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A” — Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

“High” or “low” — grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and “low” grades are not used for the AAA category.

A.M. Best Long-Term Debt Ratings

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due. These ratings are assigned to debt and preferred stock issues.

aaa — Exceptional. Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa — Very Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a — Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category. A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change. Ratings prefixed with an (“i”) denote indicative ratings. Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. Best Short-Term Debt Ratings

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

AMB-1+ — Strongest. Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1 — Outstanding. Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2 — Satisfactory. Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3 — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. Best Rating Outlook

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months. Public Data Ratings are not assigned an Outlook. Ratings Outlooks are as follows:

Positive — Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

22Table Of Contents

Negative — Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable — Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Prime Obligations Fund to Federated Prime Obligations Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Trust Shares (“Shares”). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

2Table Of Contents

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. The Fund has no present intention to engage in securities lending.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests will be rated in the highest short-term rating category (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The highest rating category of a nationally recognized statistical rating organization (NRSRO) is determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (S&P), Prime-1 by Moody’s Investors Service (“Moody’s”), F-1+ or F-1 by Fitch Ratings (“Fitch”) or R-1 (high), R-1 (middle) or R-1 (low) by Dominion Bond Rating Service (DBRS) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

3Table Of Contents

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal. The investment objective may not be changed by the Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification of Investments

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

4Table Of Contents

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending Cash or Securities

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration of Investments

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchasing on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector, and the financial services sector to include banks, broker-dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset-backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third-party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Rule 12b-1 Plan (Trust Shares)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within

6Table Of Contents

the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

7Table Of Contents

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

Committees of the Board

Board Committee	Committee Members	Committee Functions	Meetings Held During Last Fiscal Year
Executive	John F. Donahue Peter E. Madden John S. Walsh	In between meetings of the full Board, the Executive Committee generally may exercise all the powers of the full Board in the management and direction of the business and conduct of the affairs of the Trust in such manner as the Executive Committee shall deem to be in the best interests of the Trust.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

14Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

15Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

16Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies and to commodities exchange clearing corporations in connection with qualifying the Fund’s Shares for use as margin collateral. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

On July 31, 2010, the Fund owned securities of the following regular broker/dealers: BNP Paribas $1,177,500,000; Bank of America $1,475,500,000; Citigroup $1,302,900,000; Barclays Bank $2,057,500,000; Deutsche Bank $2,077,195,000; JPMorgan Chase $1,406,500,000.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

17Table Of Contents

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

Financial Information

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 — Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 — Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns “dual” ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

19Table Of Contents

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 — A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 — A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA — An obligation rated “AAA” has the highest assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA — An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A — An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (“MOODY’S”) Short-Term Municipal Obligations Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 — This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2 — This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 — Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 — Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa — Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa — Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

20Table Of Contents

A — Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR — Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) — The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) — The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) — The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Ratings Short-Term Debt Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 — Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fitch Ratings Long-Term Debt Rating Definitions

AAA — Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA — Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A — High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB — Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Fitch Ratings Commercial Paper Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

DBRS Short-Term Debt And Commercial Paper Rating Definitions

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high) — Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle) — Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

21Table Of Contents

R-1 (low) — Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low) — Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS Long-Term Debt Rating Definitions

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

“AAA” — Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA” — Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A” — Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

“High” or “low” — grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and “low” grades are not used for the AAA category.

A.M. Best Long-Term Debt Ratings

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due. These ratings are assigned to debt and preferred stock issues.

aaa — Exceptional. Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa — Very Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a — Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category. A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change. Ratings prefixed with an (“i”) denote indicative ratings. Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. Best Short-Term Debt Ratings

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

22Table Of Contents

AMB-1+ — Strongest. Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1 — Outstanding. Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2 — Satisfactory. Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3 — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. Best Rating Outlook

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months. Public Data Ratings are not assigned an Outlook. Ratings Outlooks are as follows:

Positive — Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

Negative — Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable — Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities. The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

10Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more

11Table Of Contents

susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of

12Table Of Contents

principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

13Table Of Contents

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

16Table Of Contents

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

17Table Of Contents

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

RETIREMENT INVESTMENTS

You may purchase Shares as retirement investments (such as qualified plans and IRAs or transfer or rollover of assets). Call your financial intermediary or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

19Table Of Contents

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);

20Table Of Contents

• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

21Table Of Contents

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

22Table Of Contents

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund's portfolio holdings is available in the “Products” section of Federated's website at FederatedInvestors.com. A complete listing of the Fund's portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month.

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

24Table Of Contents

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

3Table Of Contents

• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

5Table Of Contents

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

6Table Of Contents

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

7Table Of Contents

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

8Table Of Contents

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

9Table Of Contents

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities. The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

10Table Of Contents

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

11Table Of Contents

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

12Table Of Contents

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

13Table Of Contents

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

14Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

The Fund offers three Share classes: Institutional Capital Shares, Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

15Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

16Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

17Table Of Contents

Send your wire to:

State Street Bank and Trust Company

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

18Table Of Contents

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

19Table Of Contents

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or

20Table Of Contents

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

21Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

22Table Of Contents

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

23Table Of Contents

24Table Of Contents

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

25Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, fixed-income securities issued by banks, corporations and the U.S. government.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, the Fund may invest in a few government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

2Table Of Contents

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these companies.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.
• Risks of Foreign Investing. Because the Fund invests in securities issued by foreign companies, the Fund may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.
• Prepayment Risk. The Fund may invest in asset-backed and mortgage-backed securities, which may be subject to prepayment risk. If interest rates fall, and unscheduled prepayments on such securities accelerate, the Fund will be required to reinvest the proceeds at the lower interest rates then available.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risks. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of high-quality, fixed-income securities, issued by banks, corporations and the U.S. government, maturing in 397 days or less. The Fund's Adviser actively manages the Fund's portfolio, seeking to limit the credit risk taken by the Fund and to select investments with enhanced yields.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

The Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;

5Table Of Contents

• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser structures the portfolio by investing primarily in securities that pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”) and commercial paper to achieve a limited barbell structure. In this structure, the maturities of the Fund's investments tend to be concentrated towards the shorter and longer ends of the maturity range of the Fund's investments, rather than evenly spread across the range. The Adviser generally adjusts the portfolio's DWAM by increasing or decreasing the maturities of the investments at the longer end of the barbell. The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Industry Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

Temporary Investments

The Fund may temporarily depart from its principal investment strategies, including its strategy of investing at least 25% of its assets in the financial services industry, by holding cash, shortening the portfolio's DWAM, or investing in any security that is an eligible security for purchase by money market funds. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflow. It is possible that such investments could affect the Fund's investment returns and/or the Fund's ability to achieve its investment objective.

6Table Of Contents

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities in which the Fund invests:

Corporate Debt Securities (A Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities. The Fund may also purchase interests in bank loans to companies.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer's obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Demand Instruments (A Type of Corporate Debt Security)

Demand instruments are corporate debt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. Some demand instruments are “conditional,” so that the occurrence of certain conditions relieves the Demand Provider of its obligation to repurchase the security. Other demand instruments

7Table Of Contents

are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats demand instruments as short-term securities, even though their stated maturity may extend beyond one year.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker's acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Asset-Backed Securities (A Fixed-Income Security)

Asset-backed securities are payable from pools of obligations other than mortgages. Most asset-backed securities involve consumer or commercial debts with maturities of less than 10 years. However, almost any type of fixed-income assets (including other fixed-income securities) may be used to create an asset-backed security. Asset-backed securities may take the form of commercial paper, notes or pass-through certificates. Asset-backed securities have prepayment risks.

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities, including those issued by Ginnie Mae, are supported by the full faith and credit of the United States.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Freddie Mac and Fannie Mae in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Treasury Securities (A Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

8Table Of Contents

Municipal Securities (A Fixed-Income Security)

Municipal securities are issued by states, counties, cities and other political subdivisions and authorities. Although many municipal securities are exempt from federal income tax, the Fund may invest in taxable municipal securities.

Foreign Securities

Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside the United States if:

• it is organized under the laws of, or has a principal office located in, another country;
• the principal trading market for its securities is in another country; or
• it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country.

Along with the risks normally associated with domestic securities of the same type, foreign securities are subject to risks of foreign investing.

Credit Enhancement

The Fund may invest in securities that have credit enhancement. Credit enhancement consists of an arrangement in which an entity agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the entity providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit enhancement provider may have greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security. In addition, credit enhancement includes agreements to lend to the issuer amounts sufficient to repay or purchase the securities, provided that the Adviser has determined that the loan commitment will be available except under remote circumstances.

Repurchase Agreements (A Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

9Table Of Contents

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

INVESTMENT RATINGS

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities. The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7's limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund's portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal

10Table Of Contents

investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

issuer Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher-quality securities.

Many fixed-income securities receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Counterparty Credit Risk

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Sector Risks

A substantial part of the Fund's portfolio may be comprised of securities issued by companies in the financial services industry. In addition, a substantial part of the Fund's portfolio may be comprised of securities credit enhanced by companies with similar characteristics. As a result, the Fund will be more

11Table Of Contents

susceptible to any economic, business, political or other developments that generally affect these companies. Developments affecting companies in the financial services industry or companies with similar characteristics might include changes in interest rates, changes in the economic cycle affecting credit losses and regulatory changes.

Credit Enhancement Risk

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single credit enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same credit enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such a credit enhancement provider.

Risks of Foreign Investing

Foreign securities pose additional risks because foreign economic or political conditions may be less favorable than those of the United States. Securities in foreign markets may also be subject to taxation policies that reduce returns for U.S. investors.

Foreign companies may not provide information (including financial statements) as frequently or to as great an extent as companies in the United States. Foreign companies may also receive less coverage than U.S. companies by market analysts and the financial press. In addition, foreign countries may lack uniform accounting, auditing and financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies. These factors may prevent the Fund and its Adviser from obtaining information concerning foreign companies that is as frequent, extensive and reliable as the information available concerning companies in the United States.

Foreign countries may have restrictions on foreign ownership of securities or may impose exchange controls, capital flow restrictions or repatriation restrictions which could adversely affect the liquidity of the Fund's investments.

Prepayment Risks

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on asset-backed and mortgage-backed securities include both interest and a partial payment of

12Table Of Contents

principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments, which create risks that can adversely affect a fund holding such securities.

For example, when interest rates decline, the values of asset-backed and mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available.

Conversely, when interest rates rise, the values of asset-backed and mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of such securities, and cause their value to decline more than traditional fixed-income securities.

Generally, asset-backed and mortgage-backed securities compensate for the increased risk associated with prepayments by paying a higher yield. The additional interest paid for risk is measured by the difference between the yield of an asset-backed or mortgage-backed security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”). An increase in the spread will cause the price of the asset-backed or mortgage-backed security to decline. Spreads generally increase in response to adverse economic or market conditions. Spreads may also increase if the security is perceived to have an increased prepayment risk or is perceived to have less market demand.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

13Table Of Contents

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers three Share classes: Institutional Capital Shares, Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares.

14Table Of Contents

All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

15Table Of Contents

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

16Table Of Contents

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

17Table Of Contents

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

18Table Of Contents

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or

20Table Of Contents

• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

21Table Of Contents

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

22Table Of Contents

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund's portfolio holdings is available in the “Products” section of Federated's website at FederatedInvestors.com. A complete listing of the Fund's portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and remains posted until replaced by the information for the succeeding month.

Complete listings of the Fund's portfolio holdings as of the end of the Fund's first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the

23Table Of Contents

“Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC's website at www.sec.gov.

In addition, from time to time (for example, during periods of unusual market conditions), additional information regarding the Fund's portfolio holdings and/or composition may be posted to Federated's website. If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are

24Table Of Contents

generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Financial Information

FINANCIAL HIGHLIGHTS

The Financial Highlights will help you understand the Fund's financial performance for its past five fiscal years. Some of the information is presented on a per Share basis.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. Each chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in each chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund changed its name from Prime Value Obligations Fund to Federated Prime Value Obligations Fund on June 30, 2010. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established three classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares and Institutional Capital Shares (“Shares”). This SAI relates to all classes of shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Government Securities (A Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae, with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae, and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae, and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

1Table Of Contents

Zero-Coupon Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are zero-coupon securities. Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero-coupon security.

Callable Securities (A Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Mortgage-Backed Securities (A Fixed-Income Security)

Mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable interest rates. Interests in pools of adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest forms of mortgage-backed securities are pass-through certificates. An issuer of pass-through certificates gathers monthly payments from an underlying pool of mortgages. Then, the issuer deducts its fees and expenses and passes the balance of the payments onto the certificate holders once a month. Holders of pass-through certificates receive a pro rata share of all payments and prepayments from the underlying mortgages. As a result, the holders assume all the prepayment risks of the underlying mortgages.

Bank Instruments (A Fixed-Income Security)

Bank instruments are unsecured interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

The Fund will not invest in instruments of domestic and foreign banks and savings and loans unless they have capital, surplus and undivided profits of over $100,000,000, or if the principal amount of the instrument is insured by the Bank Insurance Fund or the Savings Association Insurance Fund which are administered by the Federal Deposit Insurance Corporation. These instruments may include Eurodollar Certificates of Deposit, Yankee Certificates of Deposit and Eurodollar Time Deposits.

For purposes of applying the Fund’s concentration limitation, bank instruments also include fixed-income securities credit enhanced by a bank.

Insurance Contracts (A Fixed-Income Security)

Insurance contracts include guaranteed investment contracts, funding agreements and annuities. Insurance contracts generally provide that the purchaser will deposit money with the insurance company and the insurance company will pay interest for the life of the contract and return the principal at maturity. The Fund treats these contracts as fixed-income securities.

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements (A Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation or asset coverage purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

2Table Of Contents

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Investment Ratings

The securities in which the Fund invests must be rated in one of the two highest short-term rating categories (without regard for gradations or subcategories) by one or more Nationally Recognized Statistical Rating Organizations (NRSROs) or be deemed by the Adviser to be of comparable quality to securities having such ratings. The Fund will rely on the two highest ratings given to a security by the NRSROs for purposes of complying with this requirement. If one or both of the two highest ratings are in the second highest short-term rating category, the security is treated as a Second Tier Security. Generally, Rule 2a-7 prohibits the Fund from investing more than 3% of its assets in Second Tier Securities.

The Fund complies with these rating requirements at the time a security is acquired. If a security is downgraded to Second Tier after its acquisition, the Fund may continue to hold the security even if the portfolio exceeds Rule 2a-7’s limits on Second Tier Securities. Other factors, such as substantial redemptions, may cause the Fund’s portfolio to exceed Rule 2a-7 limits on the acquisition of securities. The Fund may continue to hold securities in excess of these limits, even if the Fund has the right to tender the security for purchase for its amortized cost value.

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Risks Associated with Temporary Liquidity Guarantee Program

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (FDIC), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest, provided that the Fund has made a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. However, there is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal and liquidity. The investment objective may be changed by the Fund’s Board without shareholder approval.

Investment Limitations

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

4Table Of Contents

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans except it may make loans to affiliated investment companies in accordance with SEC exemptive relief. This restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements and/or derivative contracts, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities) if, as a result, more than 25% of the Fund’s total assets would be invested in the securities of companies whose principal business activities are in the same industry, except that the Fund will invest more than 25% of its total assets in the financial services industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, the Adviser: (a) deems the financial services industry to include the group of industries in the financial services sector; and the financial services sector to include banks, broker dealers and financial companies; (b) divides utility companies according to their services (for example, gas, gas transmission, electric and telephone); (c) classifies financial companies according to the end users of their services (for example, automobile finance, bank finance and diversified finance); (d) classifies asset backed securities according to the underlying assets securing such securities; and (e) deems investment in certain industrial development bonds funded by activities in a single industry to constitute investment in an industry. The Adviser may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third party provider used by the Adviser does not assign a classification. The Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

5Table Of Contents

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

6Table Of Contents

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund is entitled to a loss carryforward, which may reduce the taxable income or gain that the Fund would realize, and to which the shareholder would be subject, in the future.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

FOREIGN INVESTMENTS

If the Fund purchases foreign securities, their investment income may be subject to foreign withholding or other taxes that could reduce the return on these securities. Tax treaties between the United States and foreign countries, however, may reduce or eliminate the amount of foreign taxes to which the Fund would be subject. The effective rate of foreign tax cannot be predicted since the amount of Fund assets to be invested within various countries is uncertain. However, the Fund intends to operate so as to qualify for treaty-reduced tax rates when applicable.

Who Manages and Provides Services to the Fund?

Board of Trustees

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees). Unless otherwise noted, the address of each person listed is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

BOARD LEADERSHIP STRUCTURE

As required under the terms of certain regulatory settlements, the Chairman of the Board is not an interested person of the Fund and neither the Chairman, nor any firm with which the Chairman is affiliated, has a prior relationship with Federated or its affiliates or (other than his position as a Trustee) with the Fund.

Committees of the Board

Board Committee	Committee Members	Committee Functions	Meetings Held During Last Fiscal Year
Executive	John F. Donahue Peter E. Madden John S. Walsh	In between meetings of the full Board, the Executive Committee generally may exercise all the powers of the full Board in the management and direction of the business and conduct of the affairs of the Trust in such manner as the Executive Committee shall deem to be in the best interests of the Trust. However, the Executive Committee cannot elect or remove Board members, increase or decrease the number of Trustees, elect or remove any Officer, declare dividends, issue shares or recommend to shareholders any action requiring shareholder approval.

Audit	Nicholas P. Constantakis Charles F. Mansfield, Jr. Thomas M. O’Neill John S. Walsh	The purposes of the Audit Committee are to oversee the accounting and financial reporting process of the Fund, the Fund’s internal control over financial reporting and the quality, integrity and independent audit of the Fund’s financial statements. The Committee also oversees or assists the Board with the oversight of compliance with legal requirements relating to those matters, approves the engagement and reviews the qualifications, independence and performance of the Fund’s independent registered public accounting firm, acts as a liaison between the independent registered public accounting firm and the Board and reviews the Fund’s internal audit function.

The Committee will consider candidates recommended by shareholders, Independent Trustees, officers or employees of any of the Fund’s agents or service providers and counsel to the Fund. Any shareholder who desires to have an individual considered for nomination by the Committee must submit a recommendation in writing to the Secretary of the Fund, at the Fund’s address appearing on the back cover of this SAI. The recommendation should include the name and address of both the shareholder and the candidate and detailed information concerning the candidate’s qualifications and experience. In identifying and evaluating candidates for consideration, the Committee shall consider such factors as it deems appropriate. Those factors will ordinarily include: integrity, intelligence, collegiality, judgment, diversity, skill, business and other experience, qualification as an “Independent Trustee,” the existence of material relationships which may create the appearance of a lack of independence, financial or accounting knowledge and experience and dedication and willingness to devote the time and attention necessary to fulfill Board responsibilities.

BOARD’S ROLE IN RISK OVERSIGHT

The Board’s role in overseeing the Fund’s general risks includes receiving performance reports for the Fund and risk management reports from Federated’s Chief Risk Officer at each regular Board meeting. The Chief Risk Officer is responsible for enterprise risk management at Federated, which includes risk management committees for investment management and for investor services. The Board also receives regular reports from the Fund’s Chief Compliance Officer regarding significant compliance risks.

On behalf of the Board, the Audit Committee plays a key role overseeing the Fund’s financial reporting and valuation risks. The Audit Committee meets regularly with the Fund’s Principal Financial Officer and outside auditors, as well as with Federated’s Chief Audit Executive to discuss financial reporting and audit issues, including risks relating to financial controls.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

14Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

15Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

16Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

On July 31, 2010, the Fund owned securities of the following regular broker/dealers: Mizuho Bank $383,000,000; BNP Paribas $235,700,000; Citigroup $355,000,000; Bank of America $65,000,000; Deutsche Bank $200,000,000; Barclays Bank $276,500,000; Wells Fargo Bank $200,000,000.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

17Table Of Contents

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield and Effective Yield are given for the 7-day period ended July 31, 2010.

18Table Of Contents

	7-Day Period	1 Year	5 Years	10 Years

Yield	0.30%	N/A	N/A	N/A
Effective Yield	0.30%	N/A	N/A	N/A

Yield	0.20%	N/A	N/A	N/A
Effective Yield	0.20%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation RATINGS

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 — Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 — Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns “dual” ratings to all long-term debt issues that have as part of their provisions a demand feature. The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols are usually used to denote the put (demand) options (i.e., AAA/A-1+). Normally demand notes receive note-rating symbols combined with commercial paper symbols (i.e., SP-1+/A-1+).

19Table Of Contents

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 — A Short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 — A Short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA — An obligation rated “AAA” has the highest assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA — An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A — An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (“MOODY’S”) Short-Term Municipal Obligations Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 — This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG2 — This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 — Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 — Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa — Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa — Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

20Table Of Contents

A — Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR — Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) — The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) — The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) — The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Ratings Short-Term Debt Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 — Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fitch Ratings Long-Term Debt Rating Definitions

AAA — Highest credit quality. “AAA” ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA — Very high credit quality. “AA” ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A — High credit quality. “A” ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB — Good credit quality. “BBB” ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

Fitch Ratings Commercial Paper Rating Definitions

F-1 — Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 — Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

DBRS Short-Term Debt And Commercial Paper Rating Definitions

As is the case with all DBRS rating scales, commercial paper ratings are meant to give an indication of the risk that the borrower will not fulfill its obligations in a timely manner.

R-1 (high) — Short-term debt rated “R-1 (high)” is of the highest credit quality, and indicates an entity which possesses unquestioned ability to repay current liabilities as they fall due. Entities rated in this category normally maintain strong liquidity positions, conservative debt levels and profitability which is both stable and above average. Companies achieving an “R-1 (high)” rating are normally leaders in structurally sound industry segments with proven track records, sustainable positive future results and no substantial qualifying negative factors. Given the extremely tough definition which DBRS has established for an “R-1 (high),” few entities are strong enough to achieve this rating.

R-1 (middle) — Short-term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above-average strength in key areas of consideration for debt protection.

21Table Of Contents

R-1 (low) — Short-term debt rated “R-1 (low)” is of satisfactory credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

R-2 (high), R-2 (middle), R-2 (low) — Short-term debt rated “R-2” is of adequate credit quality and within the three subset grades, debt protection ranges from having reasonable ability for timely repayment to a level which is considered only just adequate. The liquidity and debt ratios of entities in the “R-2” classification are not as strong as those in the “R-1” category, and the past and future trend may suggest some risk of maintaining the strength of key ratios in these areas. Alternative sources of liquidity support are considered satisfactory; however, even the strongest liquidity support will not improve the commercial paper rating of the issuer. The size of the entity may restrict its flexibility, and its relative position in the industry is not typically as strong as an “R-1 credit.” Profitability trends, past and future, may be less favorable, earnings not as stable, and there are often negative qualifying factors present which could also make the entity more vulnerable to adverse changes in financial and economic conditions.

DBRS Long-Term Debt Rating Definitions

As is the case with all DBRS rating scales, long-term debt ratings are meant to give an indication of the risk that the borrower will not fulfill its full obligations in a timely manner with respect to both interest and principal commitments.

“AAA” — Bonds rated “AAA” are of the highest credit quality, with exceptionally strong protection for the timely repayment of principal and interest. Earnings are considered stable, the structure of the industry in which the entity operates is strong, and the outlook for future profitability is favorable. There are few qualifying factors present which would detract from the performance of the entity, the strength of liquidity and coverage ratios is unquestioned and the entity has established a creditable track record of superior performance. Given the extremely tough definition which DBRS has established for this category, few entities are able to achieve a AAA rating.

“AA” — Bonds rated “AA” are of superior credit quality, and protection of interest and principal is considered high. In many cases, they differ from bonds rated AAA only to a small degree. Given the extremely tough definition which DBRS has for the AAA category (which few companies are able to achieve), entities rated AA are also considered to be strong credits which typically exemplify above-average strength in key areas of consideration and are unlikely to be significantly affected by reasonably foreseeable events.

“A” — Bonds rated “A” are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the “A” category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher-rated companies.

“High” or “low” — grades are used to indicate the relative standing of a credit within a particular rating category. The lack of one of these designations indicates a rating which is essentially in the middle of the category. Note that “high” and “low” grades are not used for the AAA category.

A.M. Best Long-Term Debt Ratings

An A.M. Best Long-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its financial obligations to security holders when due. These ratings are assigned to debt and preferred stock issues.

aaa — Exceptional. Assigned to issues where the issuer has, in A.M. Best’s opinion, an exceptional ability to meet the terms of the obligation.

aa — Very Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a very strong ability to meet the terms of the obligation.

a — Strong. Assigned to issues where the issuer has, in A.M. Best’s opinion, a strong ability to meet the terms of the obligation.

bbb — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to meet the terms of the obligation; however, is more susceptible to changes in economic or other conditions.

Ratings from “aa” to “ccc” may be enhanced with a “+” (plus) or “-” (minus) to indicate whether credit quality is near the top or bottom of a category. A company’s Long-Term Credit Rating also may be assigned an Under Review modifier (“u”) that generally is event-driven (positive, negative or developing) and indicates that the company’s A.M. Best Rating opinion is under review and may be subject to near-term change. Ratings prefixed with an (“i”) denote indicative ratings. Ratings may also be assigned a Public Data modifier (“pd”) which indicates that a company does not subscribe to A.M. Best’s interactive rating process.

A.M. Best Short-Term Debt Ratings

An A.M. Best Short-Term Debt Rating (issue credit rating) is an opinion as to the issuer’s ability to meet its obligations having maturities generally less than one year, such as commercial paper.

22Table Of Contents

AMB-1+ — Strongest. Assigned to issues where the issuer has, in A.M. Best’s opinion, the strongest ability to repay short-term debt obligations.

AMB-1 — Outstanding. Assigned to issues where the issuer has, in A.M. Best’s opinion, an outstanding ability to repay short-term debt obligations.

AMB-2 — Satisfactory. Assigned to issues where the issuer has, in A.M. Best’s opinion, a satisfactory ability to repay short-term debt obligations.

AMB-3 — Adequate. Assigned to issues where the issuer has, in A.M. Best’s opinion, an adequate ability to repay short-term debt obligations; however, adverse economic conditions will likely lead to a reduced capacity to meet its financial commitments on short-term debt obligations.

A.M. Best Rating Outlook

A.M. Best Credit Ratings (aaa to c) are assigned a Rating Outlook that indicates the potential direction of a company’s rating for an intermediate period, generally defined as the next 12 to 36 months. Public Data Ratings are not assigned an Outlook. Ratings Outlooks are as follows:

Positive — Indicates a company’s financial/market trends are favorable, relative to its current rating level, and if continued, the company has a good possibility of having its rating upgraded.

Negative — Indicates a company is experiencing unfavorable financial/market trends, relative to its current rating level, and if continued, the company has a good possibility of having its rating downgraded.

Stable — Indicates a company is experiencing stable financial/market trends and that there is a low likelihood that its rating will change in the near term.

1 Year	$55
3 Years	$173
5 Years	$302
10 Years	$677

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. The Fund's investment Adviser (“Adviser”) also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the federal alternative minimum tax for individuals and corporations (AMT), such that, normally, distributions of annual interest income also are exempt from the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund.

The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.
• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or

3Table Of Contents

• significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be tax-exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Any Fund distributions of capital gains are taxable at applicable capital gains rates. The Fund is generally not a suitable investment for retirement accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest the Fund's assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. The Fund's Adviser also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the federal alternative minimum tax for individuals and corporations (AMT), such that, normally, distributions of annual interest income also are exempt from the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

The Adviser for the Fund targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others): current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve's monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns. In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

Because the Fund refers to tax-free investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. (Federal regular income tax does not include the federal alternative minimum tax

6Table Of Contents

or the federal alternative minimum tax for corporations.) The Fund also will invest its assets so that at least 80% of the income it distributes will be exempt from federal income tax. This policy may not be changed without shareholder approval.

Given its fundamental investment policies, the Adviser also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the AMT, such that, normally, distributions of annual interest income also are exempt from the AMT.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities

7Table Of Contents

and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

8Table Of Contents

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. However, issues are available in the marketplace that are not subject to the AMT due to qualifying tax rules.

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit

9Table Of Contents

enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

INVESTMENT RATINGS

The money market instruments in which the Fund invests will be rated in the highest short-term rating category by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

10Table Of Contents

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

11Table Of Contents

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

12Table Of Contents

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

13Table Of Contents

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

14Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other class.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors, or to individuals, directly or through financial intermediaries. The Fund may not be a suitable investment for retirement plans. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

15Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

16Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 3:00 p.m. Eastern time and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

17Table Of Contents

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

18Table Of Contents

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by noon Eastern time, and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

If you call the Fund after noon Eastern time and before the end of regular trading (normally 4:00 p.m. Eastern time) on the NYSE, you will be entitled to that day's dividend and your redemption proceeds will be sent to you the following business day.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

19Table Of Contents

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds
30 Dan Road
Canton, MA 02021

All requests must include:

• Fund Name and Share Class, account number and account registration;
• amount to be redeemed or exchanged;
• signatures of all shareholders exactly as registered; and
• if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or

20Table Of Contents

• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);
• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and

21Table Of Contents

• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

22Table Of Contents

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund's portfolio holdings is available in the “Products” section of Federated's website at FederatedInvestors.com. A complete listing of the Fund's portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

24Table Of Contents

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material

25Table Of Contents

adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.46%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund's Institutional Service Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.46% (the “Fee Limit”) through the later of (the “Termination Date”): (a) September 30, 2011; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund's Board of Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. The Fund will invest its assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. The Fund's investment Adviser (“Adviser”) also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the federal alternative minimum tax for individuals and corporations (AMT), such that, normally, distributions of annual interest income also are exempt from the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less.

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Fund's investment adviser to be reliable, pay interest that is not subject to federal regular income taxes. The types of securities in which the Fund may principally invest include: (a) tax-exempt securities such as the following types, some of which may be subject to credit enhancement: variable rate demand instruments, municipal notes, general obligation bonds, special revenue bonds, private activity bonds and tax-exempt commercial paper; and (b) interests in securities of other investment companies.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund.

The primary factors that may reduce the Fund's returns include:

• Issuer Credit Risk. There is a possibility that issuers of securities in which the Fund may invest may default on the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

2Table Of Contents

• Counterparty Credit Risk. Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.
• Interest Rate Risk. Prices of fixed-income securities (including tax-exempt securities) generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below or above its current market value.
• Sector Risk. A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics.As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these issuers or entities.
• Tax Risk. In order to be tax-exempt, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.
• Credit Enhancement Risk. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Fund shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

3Table Of Contents

• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be tax-exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Any Fund distributions of capital gains are taxable at applicable capital gains rates. The Fund is generally not a suitable investment for retirement accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of short-term, high-quality, tax-exempt securities. Issuers include states and political subdivisions, industrial and economic development authorities, school and college authorities, housing authorities, healthcare facility authorities, municipal utilities, transportation authorities and other public agencies. The Fund will invest the Fund's assets so that, normally, distributions of annual interest income are exempt from federal regular income tax. The Fund's Adviser also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the federal alternative minimum tax for individuals and corporations (AMT), such that, normally, distributions of annual interest income also are exempt from the AMT. The Fund invests in a portfolio of securities maturing in 397 days or less. Certain of the securities in which the Fund invests pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”).

The Adviser for the Fund targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as (among others): current and expected U.S. economic growth; current and expected interest rates and inflation; and the Federal Reserve's monetary policy.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns. In targeting a dollar-weighted average portfolio maturity range, the Adviser also will consider the tax-exempt securities available.

The Adviser performs a fundamental credit analysis to develop an approved database of issuers and securities that meet the Adviser's standard for minimal credit risk. The Adviser monitors the credit risks of all portfolio securities on an ongoing basis by reviewing periodic financial data and ratings of certain nationally recognized statistical rating organizations (NRSROs).

Because the Fund refers to tax-free investments in its name, it has an investment policy that it will normally invest its assets so that at least 80% of the income that it distributes will be exempt from federal regular income tax. (Federal regular income tax does not include the federal alternative minimum tax

6Table Of Contents

or the federal alternative minimum tax for corporations.) The Fund also will invest its assets so that at least 80% of the income it distributes will be exempt from federal income tax. This policy may not be changed without shareholder approval.

Given its fundamental investment policies, the Adviser also normally will invest the Fund's assets entirely in securities whose interest is not subject to (or not a specific preference item for purposes of) the AMT, such that, normally, distributions of annual interest income also are exempt from the AMT.

In order to comply with recent amendments to Rule 2a-7, the Fund will: (1) maintain a dollar-weighted average maturity (DWAM) of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in taxable securities or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate tax-exempt securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such temporary investments could affect the Fund's investment returns. If the Fund invests in taxable securities, it may receive and distribute taxable income to investors and to that extent fail to meet its investment objectives.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

TAX-EXEMPT SECURITIES

Tax-exempt securities are fixed-income securities that, in the opinion of bond counsel to the issuer or on the basis of another authority believed by the Adviser to be reliable, pay interest that is not subject to federal regular income taxes. Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Typically, states, counties, cities

7Table Of Contents

and other political subdivisions and authorities issue tax-exempt securities. The market categorizes tax-exempt securities by their source of repayment. Certain of these tax-exempt securities may be subject to credit enhancement.

Variable Rate Demand Instruments (A Type of Tax-Exempt Security)

Variable rate demand instruments are tax-exempt securities that require the issuer or a third party, such as a dealer or bank (the “Demand Provider”), to repurchase the security for its face value upon demand. The securities also pay interest at a variable rate intended to cause the securities to trade at their face value. Some variable rate demand instruments are “conditional,” so that the occurrence of certain conditions discharges the Demand Provider's obligation to repurchase the security. Other variable rate demand instruments are “unconditional,” so that there are no conditions under which the Demand Provider's obligation to repurchase the security can terminate. The Fund treats variable rate demand instruments as short-term securities even though their maturity may extend beyond 397 days because, within 397 days, their variable interest rate adjusts in response to changes in market rates and the repayment of their principal amount can be demanded. Certain variable rate demand instruments that may be invested in by the Fund, referred to as “synthetic” variable rate demand instruments, have certain features, such as call features, that make it possible that the Fund will realize capital gains.

Municipal Notes (A Type of Tax-Exempt Security)

Municipal notes are short-term, tax-exempt securities. Many municipalities issue such notes to fund their current operations before collecting taxes or other municipal revenues. Municipalities may also issue notes to fund capital projects prior to issuing long-term bonds. The issuers typically repay the notes at the end of their fiscal year, either with taxes, other revenues or proceeds from newly issued notes or bonds.

General Obligation Bonds (A Type of Tax-Exempt Security)

General obligation bonds are supported by the issuer's power to exact property or other taxes. The issuer must impose and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer's authority to impose additional taxes may be limited by its charter or state law.

Special Revenue Bonds (A Type of Tax-Exempt Security)

Special revenue bonds are payable solely from specific revenues received by the issuer such as specific taxes, assessments, tolls or fees. Bondholders may not collect from the municipality's general taxes or revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Therefore, a shortfall in the tolls normally would result in a default on the bonds, or in certain cases, may result in a reduction in payments received in respect of the bonds.

8Table Of Contents

Private Activity Bonds (A Type of Special Revenue Bond)

Private activity bonds are special revenue bonds used to finance private projects. A certain percentage of the proceeds from a private activity bond is used for a private business use or a certain percentage of the debt service regarding a private activity bond is paid directly or indirectly from a private business use. A private business use is a trade or business carried on by any person or entity other than a governmental unit. Private activity bonds are secured primarily by revenues derived from loan repayments or lease payments due from the private entity, which may or may not be guaranteed by a parent company or otherwise secured. Private activity bonds generally are not secured by a pledge of the taxing power of the issuer of such bonds. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds from its bonds to the company using the factory, and the company would agree to make loan payments sufficient to cover interest and principal payments on the bonds. The bonds would be payable from the company's loan payments, and generally not from any other revenues of the municipality. Therefore, any default of the loan normally would result in a default on the bonds.

Types of private activity bonds include, for example: bonds issued to obtain funds to provide water, sewage and solid waste facilities, qualified residential rental projects, certain local electric, gas and other heating and cooling facilities, qualified hazardous waste facilities, high-speed intercity rail facilities, certain airports, docks, wharves and mass transportation facilities and qualified mortgages; qualified student loan bonds; qualified redevelopment bonds; and bonds used for certain organizations exempt from federal income taxation (qualified 501(c)(3) bonds).

The interest on many types of private activity bonds is subject to the AMT. However, issues are available in the marketplace that are not subject to the AMT due to qualifying tax rules.

Tax-Exempt Commercial Paper (A Type of Tax-Exempt Security)

Tax-exempt commercial paper is an obligation issued by a tax-exempt issuer with a maturity of less than nine months. Tax-exempt issuers may issue commercial paper to pay for current expenditures or other permissible activities. Tax-exempt issuers may constantly reissue their commercial paper and use the proceeds (or other sources) to repay maturing paper. If the tax-exempt issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default.

Credit Enhancement

The Fund may invest in tax-exempt securities with credit enhancement. Credit enhancement consists of an arrangement in which a company agrees to pay amounts due on a fixed-income security if the issuer defaults. In some cases the company providing credit enhancement makes all payments directly to the security holders and receives reimbursement from the issuer. Normally, the credit

9Table Of Contents

enhancer has greater financial resources and liquidity than the issuer. For this reason, the Adviser may evaluate the credit risk of a fixed-income security based solely upon its credit enhancement.

Common types of credit enhancement include guarantees, letters of credit, bond insurance and surety bonds. Credit enhancement also includes arrangements where securities or other liquid assets secure payment of a fixed-income security. If a default occurs, these assets may be sold and the proceeds paid to the security's holders. Either form of credit enhancement reduces credit risks by providing another source of payment for a fixed-income security.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in shares of other investment companies as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These investments may include shares of an affiliated money market fund; or preferred shares of a closed-end fund that are eligible for purchase by money market funds (generally, because such preferred shares are structured as unconditional demand instruments with a third-party Demand Provider). Other investment companies are managed independently of the Fund and incur additional fees and/or expenses which would, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses. The Fund may invest in money market securities directly.

INVESTMENT RATINGS

The money market instruments in which the Fund invests will be rated in the highest short-term rating category by one or more NRSROs or be deemed by the Adviser to be of comparable quality to securities having such ratings.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

ISSUER Credit Risk

Issuer credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Money market funds try to minimize this risk by purchasing higher quality securities.

10Table Of Contents

Many fixed-income securities (including tax-exempt securities) receive credit ratings from NRSROs such as Standard & Poor's and Moody's Investor Services, Inc. These NRSROs assign ratings to securities by assessing the likelihood of issuer default. Lower credit ratings correspond to higher perceived credit risk and higher credit ratings correspond to lower perceived credit risk. Credit ratings do not provide assurance against default or other loss of money. If a security has not received a rating, the Fund must rely entirely upon the Adviser's credit assessment.

Fixed-income securities generally compensate for greater credit risk by paying interest at a higher rate. The difference between the yield of a security and the yield of a U.S. Treasury security or other appropriate benchmark with a comparable maturity (the “spread”) measures the additional interest paid for risk. Spreads may increase generally in response to adverse economic or market conditions. A security's spread may also increase if the security's rating is lowered, or the security is perceived to have an increased credit risk. An increase in the spread will cause the price of the security to decline.

Finally, the securities in which the Fund invests may include those issued by a state or local government, or other political subdivisions or authorities, or directly or indirectly supported by taxes, assessments, tolls, fees or other revenue collected by or otherwise derived by or through such issuers. Such securities, like other securities that may be invested in by the Fund, have credit risk. Like other issuers, there is no guarantee that the issuers of such securities will have sufficient revenues to satisfy their obligations (such as, for example, the payment of interest or principal when due) with respect to such securities invested by the Fund. For example, in the case of certain of these issuers, legal, economic, political or other developments may raise impairments (such as, for example, limitations under state law on the issuer's authority to raise taxes, prolonged budgetary processes, declining real estate values and declining tax revenues) to such an issuer's budgetary flexibility and liquidity, and its ability to satisfy its obligations with respect to such securities invested in by the Fund. Such impairments may cause a downgrade in the credit ratings of such an issuer, or the securities issued or supported by it, and may cause such an issuer to defer payment of certain obligations, reduce or eliminate appropriations and/or default on its obligations. In such situations, the credit risk of such securities invested in by the Fund will increase. Like other issuers and securities, the likelihood that the credit risk associated with such issuers and such securities will increase is greater during times of economic stress and financial instability. As a result, in such situations, there would be heightened risk that there could be an interruption in payments to bondholders in some cases. There also could be a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund's net asset value or the distributions paid by the Fund.

11Table Of Contents

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

Interest Rate Risk

Prices of fixed-income securities (including tax-exempt securities) rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall, while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

Certain factors, such as the presence of call features, may cause a particular fixed-income security, or the Fund as a whole, to exhibit less sensitivity to changes in interest rates.

Certain of the Fund's investments may also be valued, in part, by reference to the relative relationship between interest rates on tax-exempt securities and taxable securities, respectively. When the market for tax-exempt securities underperforms (or outperforms) the market for taxable securities, the value of these investments may be negatively affected (or positively affected).

Call Risk

Call risk is the possibility that an issuer may redeem a fixed-income security (including a tax-exempt security) before maturity (a “call”) at a price below or above its current market price. An increase in the likelihood of a call may reduce the security's price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Sector Risk

A substantial part of the Fund's portfolio may be comprised of securities issued or credit enhanced by companies in similar businesses or with other similar characteristics. As a result, the Fund will be more susceptible to any economic, business, political or other developments which generally affect these entities. Developments affecting companies with similar characteristics might include changes in interest rates, changes in economic cycles affecting credit losses and regulatory changes.

12Table Of Contents

TAX RISK

In order to pay interest that is exempt from federal regular income tax, tax-exempt securities must meet certain legal requirements. Failure to meet such requirements may cause the interest received and distributed by the Fund to shareholders to be taxable.

Changes or proposed changes in federal or state tax laws may cause the prices of tax-exempt securities to fall and/or may affect the tax-exempt status of the securities in which the Fund invests.

CREDIT ENHANCEMENT RISK

The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit or bond insurance). Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security's value due to changes in market conditions. Securities subject to credit enhancement generally would be assigned a lower credit rating if the rating were based primarily on the credit quality of the issuer without regard to the credit enhancement. If the credit quality of the credit enhancement provider (for example, a bank or bond insurer) is downgraded, the rating on a security credit enhanced by such credit enhancement provider also may be downgraded.

A single enhancement provider may provide credit enhancement to more than one of the Fund's investments. Having multiple securities credit enhanced by the same enhancement provider will increase the adverse effects on the Fund that are likely to result from a downgrading of, or a default by, such an enhancement provider. Adverse developments in the banking or bond insurance industries also may negatively affect the Fund, as the Fund may invest in securities credit enhanced by banks or by bond insurers without limit. Bond insurers that provide credit enhancement for large segments of the fixed-income markets, including the municipal bond market, may be more susceptible to being downgraded or defaulting during recessions or similar periods of economic stress.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

13Table Of Contents

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per share and its market-based NAV per share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

14Table Of Contents

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at noon and 3:00 p.m. Eastern time and as of the end of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) each day the NYSE is open. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. The additional class of Shares, which is offered by separate prospectus, may be preferable for certain shareholders. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other class.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors, or to individuals, directly or through financial intermediaries. The Fund may not be a suitable investment for retirement plans. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

15Table Of Contents

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

16Table Of Contents

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 3:00 p.m. Eastern time and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

17Table Of Contents

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

18Table Of Contents

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by noon Eastern time, and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

If you call the Fund after noon Eastern time and before the end of regular trading (normally 4:00 p.m. Eastern time) on the NYSE, you will be entitled to that day's dividend and your redemption proceeds will be sent to you the following business day.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

19Table Of Contents

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds
30 Dan Road
Canton, MA 02021

All requests must include:

• Fund Name and Share Class, account number and account registration;
• amount to be redeemed or exchanged;
• signatures of all shareholders exactly as registered; and
• if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or

20Table Of Contents

• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption In-Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed for up to seven days:

• to allow your purchase to clear (as discussed below);
• during periods of market volatility;
• when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets; or
• during any period when the Federal Reserve wire or applicable Federal Reserve banks are closed, other than customary weekend and holiday closings.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

In addition, the right of redemption may be suspended, or the payment of proceeds may be delayed, during any period:

• when the NYSE is closed, other than customary weekend and holiday closings;
• when trading on the NYSE is restricted, as determined by the SEC;
• in which an emergency exists, as determined by the SEC, so that disposal of the Fund's investments or determination of its NAV is not reasonably practicable; or
• in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and rules thereunder, of the Investment Company Act of 1940.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and

21Table Of Contents

• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

The Fund does not expect to realize any capital gains or losses. However, the Fund may realize capital gains on certain securities, such as synthetic variable rate demand instruments, that may be redeemed in certain circumstances at a premium to their face value. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks. See “Tax Information” below for information on the tax consequences of the Fund realizing a capital gain.

22Table Of Contents

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund's distributions, if applicable, is available in the “Products” section of Federated's website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders - Source of Distributions” link under “Related Information.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. It is anticipated that Fund distributions will be primarily dividends that are exempt from federal regular income tax, although a portion of the Fund's dividends may not be exempt. Dividends may be subject to state and local taxes. Although the Fund does not seek to realize capital gains, the Fund may realize and distribute capital gains from time to time as a result of the Fund's normal investment activities. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares. Capital gains and non-exempt dividends are taxable whether paid in cash or reinvested in the Fund. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

PORTFOLIO HOLDINGS INFORMATION

Information concerning the Fund's portfolio holdings is available in the “Products” section of Federated's website at FederatedInvestors.com. A complete listing of the Fund's portfolio holdings as of the end of each month is posted on the website 15 days (or the next business day) after the end of the month and

If and when such information is posted, its availability will be noted on, and the information will be accessible from, the home page of the website.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

24Table Of Contents

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material

25Table Of Contents

adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund was reorganized as a portfolio of the Trust on December 11, 1989. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (“Board”) has established two classes of shares of the Fund, known as Institutional Shares and Institutional Service Shares (“Shares”). This SAI relates to Institutional Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”). Effective June 30, 2010, the Fund changed its name from “Tax-Free Obligations Fund” to “Federated Tax-Free Obligations Fund.”

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund may invest:

Municipal Leases (A Type of Tax-Exempt, Fixed-Income Security)

Municipalities may enter into leases for equipment or facilities. In order to comply with state public financing laws, these leases are typically subject to annual appropriation. In other words, a municipality may end a lease, without penalty, by not providing for the lease payments in its annual budget. After the lease ends, the lessor can resell the equipment or facility but may lose money on the sale. The Fund may invest in securities supported by pools of municipal leases. The most common type of lease-backed securities are certificates of participation (COPs). However, the Fund may also invest directly in individual leases.

Callable Securities (A Type of Tax-Exempt, Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Certain callable securities invested in by the Fund also may be callable by parties other than the issuer. Callable securities are subject to call risks.

Zero-Coupon Securities (A Type of Tax-Exempt, Fixed-Income Security)

Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero-coupon security.

There are many forms of zero-coupon securities. Some are issued at a discount and are referred to as zero-coupon or capital-appreciation bonds. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

1Table Of Contents

Tax Increment Financing Bonds (A Type of Tax-Exempt, Fixed-Income Security)

Tax increment financing (TIF) bonds are payable from increases in taxes or other revenues attributable to projects within the TIF district. For example, a municipality may issue TIF bonds to redevelop a commercial area. The TIF bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could fail to pay principal or interest if merchants’ sales, and related tax collections, failed to increase as anticipated.

Municipal Mortgage-Backed Securities (A Type of Tax-Exempt, Fixed-Income Security)

Municipal mortgage-backed securities are special revenue bonds the proceeds of which may be used to provide mortgage loans for single family homes or to finance multifamily housing. Municipal mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable rates. Interests in pools of adjustable-rate mortgages are known as ARMs. Municipal mortgage-backed securities generally have fixed interest rates.

Municipal mortgage-backed securities come in a variety of forms. The simplest forms of municipal mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other municipal mortgage-backed securities may have more complicated financial structures.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

2Table Of Contents

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. These transactions may create leverage risks.

Temporary Investments

The Fund may make temporary investments in taxable, fixed-income securities and the following other taxable securities:

Treasury Securities (A Type of Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Type of Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Bank Instruments (A Type of Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Corporate Debt Securities (A Type of Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default. The short maturity of commercial paper generally reduces both the market and credit risks as compared to other debt securities of the same issuer.

Repurchase Agreements (A Type of Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks. In addition to taxable repurchase agreements, the Fund also may invest in municipal repurchase agreements as a non-principal investment.

Reverse Repurchase Agreements (A Type of Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase. In addition to taxable reverse repurchase agreements, the Fund also may invest in municipal reverse repurchase agreements as a non-principal investment.

Investment Ratings

The securities in which the Fund invests must be rated in the highest short-term rating categories by one or more nationally recognized statistical rating organizations (NRSROs) or deemed by the Adviser to be of comparable quality to securities having such ratings. An NRSROs highest rating categories are determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (“S&P”), Prime-1 by Moody’s Investors Service (“Moody’s”), or F-1+ or F-1 by Fitch Ratings (“Fitch”) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

4Table Of Contents

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective (and Policies) and Investment Limitations

The investment objective of the Fund is to provide dividend income exempt from federal regular income tax consistent with stability of principal. At least 80% of the Fund’s annual interest income will be exempt from federal regular income tax. (Federal regular income tax does not include the federal alternative minimum tax or the federal alternative minimum tax for corporations.) The Fund also will invest its assets so that at least 80% of the income that it distributes will be exempt from federal income tax.

The investment objective and investment policy may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,’’ as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

5Table Of Contents

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation: to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

For purposes of the concentration limitation: (a) utility companies will be divided according to their services (for example, gas, gas transmission, electric and telephone will each be considered a separate industry); (b) financial service companies will be classified according to the end users of their services (for example, automobile finance, bank finance and diversified finance will each be considered a separate industry); and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

6Table Of Contents

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

7Table Of Contents

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A special meeting of shareholders will be called by the Board upon the written request of shareholders who own at least 10% of the Trust’s outstanding shares of all series entitled to vote.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

15Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

16Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website.

Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

17Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10 Years
Institutional Shares:
Total Return		0.18%	2.17%	1.99%
Yield	0.13%	N/A	N/A	N/A
Effective Yield	0.13%	N/A	N/A	N/A
Tax-Equivalent Yield	0.20%	N/A	N/A	N/A

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

19Table Of Contents

Yield, Effective Yield and Tax-Equivalent Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

The tax-equivalent yield of Shares is calculated similarly to the yield, but is adjusted to reflect the taxable yield that Shares would have had to earn to equal the actual yield, assuming the maximum combined federal and state tax rate. To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

20Table Of Contents

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund was reorganized as a portfolio of the Trust on December 11, 1989. The Trust may offer separate series of shares representing interests in separate portfolios of securities.

The Board of Trustees (Board) has established two classes of shares of the Fund, known as Institutional Shares and Institutional Service Shares (Shares). This SAI relates to both classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (Adviser). Effective June 30, 2010, the Fund changed its name from “Tax-Free Obligations Fund” to “Federated Tax-Free Obligations Fund.”

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Fixed-Income Securities

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or may be adjusted periodically. In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time. Fixed-income securities provide more regular income than equity securities. However, the returns on fixed-income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed-income securities as compared to equity securities.

A security’s yield measures the annual income earned on a security as a percentage of its price. A security’s yield will increase or decrease depending upon whether it costs less (a “discount”) or more (a “premium”) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund may invest:

Municipal Leases (A Type of Tax-Exempt, Fixed-Income Security)

Municipalities may enter into leases for equipment or facilities. In order to comply with state public financing laws, these leases are typically subject to annual appropriation. In other words, a municipality may end a lease, without penalty, by not providing for the lease payments in its annual budget. After the lease ends, the lessor can resell the equipment or facility but may lose money on the sale. The Fund may invest in securities supported by pools of municipal leases. The most common type of lease-backed securities are certificates of participation (COPs). However, the Fund may also invest directly in individual leases.

Callable Securities (A Type of Tax-Exempt, Fixed-Income Security)

Certain fixed-income securities in which the Fund invests are callable at the option of the issuer. Certain callable securities invested in by the Fund also may be callable by parties other than the issuer. Callable securities are subject to call risks.

Zero-Coupon Securities (A Type of Tax-Exempt, Fixed-Income Security)

Zero-coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero-coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero-coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero-coupon security.

There are many forms of zero-coupon securities. Some are issued at a discount and are referred to as zero-coupon or capital-appreciation bonds. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

1Table Of Contents

Tax Increment Financing Bonds (A Type of Tax-Exempt, Fixed-Income Security)

Tax increment financing (TIF) bonds are payable from increases in taxes or other revenues attributable to projects within the TIF district. For example, a municipality may issue TIF bonds to redevelop a commercial area. The TIF bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could fail to pay principal or interest if merchants’ sales, and related tax collections, failed to increase as anticipated.

Municipal Mortgage-Backed Securities (A Type of Tax-Exempt, Fixed-Income Security)

Municipal mortgage-backed securities are special revenue bonds the proceeds of which may be used to provide mortgage loans for single family homes or to finance multifamily housing. Municipal mortgage-backed securities represent interests in pools of mortgages. The mortgages that comprise a pool normally have similar interest rates, maturities and other terms. Mortgages may have fixed or adjustable rates. Interests in pools of adjustable-rate mortgages are known as ARMs. Municipal mortgage-backed securities generally have fixed interest rates.

Municipal mortgage-backed securities come in a variety of forms. The simplest forms of municipal mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other municipal mortgage-backed securities may have more complicated financial structures.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Securities Lending

The Fund may lend portfolio securities to borrowers that the Adviser deems creditworthy. In return, the Fund receives cash or liquid securities from the borrower as collateral. The borrower must furnish additional collateral if the market value of the loaned securities increases. Also, the borrower must pay the Fund the equivalent of any dividends or interest received on the loaned securities.

The Fund will reinvest cash collateral in securities that qualify as an acceptable investment for the Fund. However, the Fund must pay interest to the borrower for the use of cash collateral.

2Table Of Contents

Loans are subject to termination at the option of the Fund or the borrower. The Fund will not have the right to vote on securities while they are on loan. However, the Fund will attempt to terminate a loan in an effort to reacquire the securities in time to vote on matters that are deemed to be material by the Adviser. There can be no assurance that the Fund will have sufficient notice of such matters to be able to terminate the loan in time to vote thereon. The Fund may pay administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash collateral to a securities lending agent or broker.

Securities lending activities are subject to interest rate risks and credit risks. These transactions may create leverage risks.

Temporary Investments

The Fund may make temporary investments in taxable, fixed-income securities and the following other taxable securities:

Treasury Securities (A Type of Fixed-Income Security)

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

Government Securities (A Type of Fixed-Income Security)

Government securities are issued or guaranteed by a federal agency or instrumentality acting under federal authority. Some government securities are supported by the full faith and credit of the United States. These include the Government National Mortgage Association (“Ginnie Mae”), Small Business Administration, Federal Financing Bank, Department of Housing and Urban Development, Export-Import Bank and Overseas Private Investment Corporation and the Federal Deposit Insurance Corporation.

Other government securities receive support through federal subsidies, loans or other benefits. For example, the U.S. Treasury is authorized to purchase specified amounts of securities issued by (or otherwise make funds available to) the Federal Home Loan Bank System, Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”) and Tennessee Valley Authority in support of such obligations.

A few government securities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities. These include Farm Credit System and Financing Corporation securities.

Investors regard government securities as having low credit risks, but not as low as Treasury securities.

The Fund treats mortgage-backed securities guaranteed by a federal agency or instrumentality as government securities. Although such a guarantee protects against credit risks, it does not reduce other risks.

Recent Events Related to Freddie Mac and Fannie Mae. The extreme and unprecedented volatility and disruption that impacted the capital and credit markets beginning in 2008 led to market concerns regarding the ability of Freddie Mac and Fannie Mae to withstand future credit losses associated with securities held in their investment portfolios, and on which they provide guarantees, without the direct support of the federal government. On September 7, 2008, both Freddie Mac and Fannie Mae were placed under the conservatorship of the Federal Housing Finance Agency (FHFA), a newly created independent regulator. Under the plan of conservatorship, the FHFA assumed control of, and generally has the power to direct, the operations of Freddie Mac and Fannie Mae, and is empowered to exercise all powers collectively held by their respective shareholders, directors and officers, including the power to: (1) take over the assets of and operate Freddie Mac and Fannie Mae with all the powers of the shareholders, the directors and the officers of Freddie Mac and Fannie Mae and conduct all business of Freddie Mac and Fannie Mae; (2) collect all obligations and money due to Freddie Mac and Fannie Mae; (3) perform all functions of Freddie Mac and Fannie Mae which are consistent with the conservator’s appointment; (4) preserve and conserve the assets and property of Freddie Mac and Fannie Mae; and (5) contract for assistance in fulfilling any function, activity, action or duty of the conservator.

In connection with the actions taken by the FHFA, the Treasury has entered into certain preferred stock purchase agreements (SPAs) with each of Freddie Mac and Fannie Mae which establish the Treasury as the holder of a new class of senior preferred stock in each of Freddie Mac and Fannie Mae. The senior preferred stock was issued in connection with financial contributions from the Treasury to Freddie Mac and Fannie Mae; the Treasury is obligated to provide such financial contributions under the SPAs through 2012. The SPAs impose significant restrictions on the activities of Freddie Mac and Fannie Mae.

The future status and role of Freddie Mac and Fannie Mae could be impacted by (among other things) the actions taken and restrictions placed on Freddie Mac and Fannie Mae by the FHFA in its role as conservator, the restrictions placed on Freddie Mac’s and Fannie Mae’s operations and activities under the SPAs, market responses to developments at Freddie Mac and Fannie Mae and future legislative and regulatory action that alters the operations, ownership, structure and/or mission of these institutions, each of which may, in turn, impact the value of, and cash flows on, any securities guaranteed by Freddie Mac and Fannie Mae.

Bank Instruments (A Type of Fixed-Income Security)

Bank instruments are unsecured, interest-bearing deposits with banks. Bank instruments include, but are not limited to, bank accounts, time deposits, certificates of deposit and banker’s acceptances. Yankee instruments are denominated in U.S. dollars and issued by U.S. branches of foreign banks. Eurodollar instruments are denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks.

Corporate Debt Securities (A Type of Fixed-Income Security)

Corporate debt securities are fixed-income securities issued by businesses. Notes, bonds, debentures and commercial paper are the most prevalent types of corporate debt securities.

Commercial Paper (A Type of Corporate Debt Security)

Commercial paper is an issuer’s obligation with a maturity of less than nine months. Companies typically issue commercial paper to pay for current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. If the issuer cannot continue to obtain liquidity in this fashion, its commercial paper may default. The short maturity of commercial paper generally reduces both the market and credit risks as compared to other debt securities of the same issuer.

Repurchase Agreements (A Type of Fixed-Income Security)

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund’s return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund’s custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks. In addition to taxable repurchase agreements, the Fund also may invest in municipal repurchase agreements as a non-principal investment.

Reverse Repurchase Agreements (A Type of Fixed-Income Security)

Reverse repurchase agreements (which are considered a type of special transaction for asset segregation purposes) are repurchase agreements in which the Fund is the seller (rather than the buyer) of the securities, and agrees to repurchase them at an agreed-upon time and price. A reverse repurchase agreement may be viewed as a type of borrowing by the Fund. Reverse repurchase agreements are subject to credit risks. In addition, reverse repurchase agreements create leverage risks because the Fund must repurchase the underlying security at a higher price, regardless of the market value of the security at the time of repurchase. In addition to taxable reverse repurchase agreements, the Fund also may invest in municipal reverse repurchase agreements as a non-principal investment.

Investment Ratings

The securities in which the Fund invests must be rated in the highest short-term rating categories by one or more nationally recognized statistical rating organizations (NRSROs) or deemed by the Adviser to be of comparable quality to securities having such ratings. An NRSROs highest rating categories are determined without regard for sub-categories and gradations. For example, securities rated A-1+ or A-1 by Standard & Poor’s (“S&P”), Prime-1 by Moody’s Investors Service (“Moody’s”), or F-1+ or F-1 by Fitch Ratings (“Fitch”) are all considered rated in the highest short-term rating category. The Fund will follow applicable regulations in determining whether a security rated by more than one rating service can be treated as being in the highest short-term rating category. See “Regulatory Compliance.”

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Leverage Risks

Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

4Table Of Contents

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective (and Policies) and Investment Limitations

The investment objective of the Fund is to provide dividend income exempt from federal regular income tax consistent with stability of principal. At least 80% of the Fund’s annual interest income will be exempt from federal regular income tax. (Federal regular income tax does not include the federal alternative minimum tax or the federal alternative minimum tax for corporations.) The Fund also will invest its assets so that at least 80% of the income that it distributes will be exempt from federal income tax.

The investment objective and investment policy may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,’’ as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

5Table Of Contents

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation: to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

For purposes of the concentration limitation: (a) utility companies will be divided according to their services (for example, gas, gas transmission, electric and telephone will each be considered a separate industry); (b) financial service companies will be classified according to the end users of their services (for example, automobile finance, bank finance and diversified finance will each be considered a separate industry); and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

6Table Of Contents

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

7Table Of Contents

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Redemption In-Kind

Although the Fund generally intends to pay Share redemptions in cash, it reserves the right, on its own initiative or in response to a shareholder request, to pay the redemption price in whole or in part by a distribution of the Fund’s portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund elects to pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV.

Redemption in-kind is not as liquid as a cash redemption. Shareholders receiving the portfolio securities could have difficulty selling them, may incur related transaction costs and would be subject to risks of fluctuations in the securities’ values prior to sale.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

Voting Rights

Each Share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

All shares of the Trust have equal voting rights, except that in matters affecting only a particular fund or class, only shares of that fund or class are entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A special meeting of shareholders will be called by the Board upon the written request of shareholders who own at least 10% of the Trust’s outstanding shares of all series entitled to vote.

Tax Information

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

Who Manages and Provides Services to the Fund?

Board of Trustees

The Board of Trustees is responsible for managing the Trust’s business affairs and for exercising all the Trust’s powers except those reserved for the shareholders. The following tables give information about each Trustee and the senior officers of the Fund. Where required, the tables separately list Trustees who are “interested persons” of the Fund (i.e., “Interested” Trustees) and those who are not (i.e., “Independent” Trustees). Unless otherwise noted, the address of each person listed is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

15Table Of Contents

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee

16Table Of Contents

member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF.

This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

17Table Of Contents

Firms that provide administrative, custody, financial, accounting, legal or other services to the Fund may receive nonpublic information about Fund portfolio holdings for purposes relating to their services. The Fund may also provide portfolio holdings information to publications that rate, rank or otherwise categorize investment companies. Traders or portfolio managers may provide “interest” lists to facilitate portfolio trading if the list reflects only that subset of the portfolio for which the trader or portfolio manager is seeking market interest. A list of service providers, publications and other third parties who may receive nonpublic portfolio holdings information appears in the Appendix to this SAI.

The furnishing of nonpublic portfolio holdings information to any third party (other than authorized governmental or regulatory personnel) requires the prior approval of the President of the Adviser and of the Chief Compliance Officer of the Fund. The President of the Adviser and the Chief Compliance Officer will approve the furnishing of nonpublic portfolio holdings information to a third party only if they consider the furnishing of such information to be in the best interests of the Fund and its shareholders. In that regard, and to address possible conflicts between the interests of Fund shareholders and those of the Adviser and its affiliates, the following procedures apply. No consideration may be received by the Fund, the Adviser, any affiliate of the Adviser or any of their employees in connection with the disclosure of portfolio holdings information. Before information is furnished, the third party must sign a written agreement that it will safeguard the confidentiality of the information, will use it only for the purposes for which it is furnished and will not use it in connection with the trading of any security. Persons approved to receive nonpublic portfolio holdings information will receive it as often as necessary for the purpose for which it is provided. Such information may be furnished as frequently as daily and often with no time lag between the date of the information and the date it is furnished. The Board receives and reviews annually a list of the persons who receive nonpublic portfolio holdings information and the purposes for which it is furnished.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the 7-day period ended July 31, 2010.

	7-Day Period	1 Year	5 Years	10 Years
Institutional Shares:

Yield	0.13%	N/A	N/A	N/A

Tax-Equivalent Yield	0.20%	N/A	N/A	N/A

Effective Yield	0.01%	N/A	N/A	N/A
Tax-Equivalent Yield	0.02%	N/A	N/A	N/A

19Table Of Contents

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield, Effective Yield and Tax-Equivalent Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.

The tax-equivalent yield of Shares is calculated similarly to the yield, but is adjusted to reflect the taxable yield that Shares would have had to earn to equal the actual yield, assuming the maximum combined federal and state tax rate. To the extent financial intermediaries charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

Investment Ratings

Standard & Poor’s (S&P) Short-Term Municipal Obligation Ratings

An S&P note rating reflects the liquidity concerns and market access risks unique to notes.

SP-1 - Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus sign (+) designation.

SP-2 - Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

S&P Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

S&P assigns dual ratings to all long-term debt issues that have as part of their provisions a variable rate demand feature. The first rating (long-term rating) addresses the likelihood of repayment of principal and interest when due, and the second rating (short-term rating) describes the demand characteristics. Several examples are AAA/A-1+, AA/A-1+, A/A-1. (The definitions for the long-term and the short-term ratings are provided below.)

S&P Commercial Paper (CP) Ratings

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

A-1 - A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2 - A short-term obligation rated “A-2” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

20Table Of Contents

S&P Long-Term Debt Ratings

AAA - An obligation rated “AAA” has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA - An obligation rated “AA” differs from the highest rated obligations only in a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

A - An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

Moody’s Investors Service (Moody’s) Short-Term Municipal Obligation Ratings

Moody’s short-term ratings are designated Moody’s Investment Grade (MIG or VMIG). (See below.) The purpose of the MIG or VMIG ratings is to provide investors with a simple system by which the relative investment qualities of short-term obligations may be evaluated.

MIG1 - This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad based access to the market for refinancing.

MIG2 - This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

Moody’s Variable Rate Demand Notes (VRDNs) And Tender Option Bonds (TOBs) Ratings

Short-term ratings on issues with demand features are differentiated by the use of the VMIG symbol to reflect such characteristics as payment upon periodic demand rather than fixed maturity dates and payment relying on external liquidity. In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1); the first representing an evaluation of the degree of risk associated with scheduled principal and interest payments, and the second representing an evaluation of the degree of risk associated with the demand feature. The VMIG rating can be assigned a 1 or 2 designation using the same definitions described above for the MIG rating.

Moody’s Commercial Paper (CP) Ratings

Prime-1 - Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics: leading market positions in well established industries, high rates of return on funds employed, conservative capitalization structure with moderate reliance on debt and ample asset protection, broad margins in earning coverage of fixed financial charges and high internal cash generation, and well-established access to a range of financial markets and assured sources of alternate liquidity.

Prime-2 - Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above, but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Moody’s Long-Term Debt Ratings

Aaa - Bonds and preferred stock which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as “gilt edged.” Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues.

Aa - Bonds and preferred stock which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk appear somewhat larger than the Aaa securities.

A - Bonds and preferred stock which are rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment some time in the future.

NR - Indicates that both the bonds and the obligor or credit enhancer are not currently rated by S&P or Moody’s with respect to short-term indebtedness. However, management considers them to be of comparable quality to securities rated A-1 or P-1.

NR(1) - The underlying issuer/obligor/guarantor has other outstanding debt rated AAA by S&P or Aaa by Moody’s.

NR(2) - The underlying issuer/obligor/guarantor has other outstanding debt rated AA by S&P or Aa by Moody’s.

NR(3) - The underlying issuer/obligor/guarantor has other outstanding debt rated A by S&P or Moody’s.

21Table Of Contents

Fitch Short-Term Debt Rating Definitions

F-1 - Indicates the strongest capacity for timely payment of financial commitments relative to other issuers or issues in the same country. Under their national rating scale, this rating is assigned to the “best” credit risk relative to all others in the same country and is normally assigned to all financial commitments issued or guaranteed by the sovereign state. Where the credit risk is particularly strong, a “+” is added to the assigned rating.

F-2 - Indicates a satisfactory capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, the margin of safety is not as great as in the case of the higher ratings.

F-3 - Indicates an adequate capacity for timely payment of financial commitments relative to other issuers or issues in the same country. However, such capacity is more susceptible to near-term adverse changes than for financial commitments in higher-rated categories.

Fund Summary Information

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per Share. The Fund seeks to provide current income consistent with stability of principal.

RISK/RETURN SUMMARY: FEES AND EXPENSES

This table describes the fees and expenses that you may pay if you buy and hold Institutional Capital Shares of the Fund.

Shareholder Fees
Fees Paid Directly From Your Investment
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, as applicable)	None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends (and other Distributions) (as a percentage of offering price)	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None
Exchange Fee	None
Annual Fund Operating Expenses
Expenses That You Pay Each Year as a Percentage of the Value of Your Investment
Management Fee	0.20%
Distribution (12b-1) Fee	None
Other Expenses	0.33%
Total Annual Fund Operating Expenses	0.53%
Fee Waivers and/or Expense Reimbursements1	0.23%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.30%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund's Institutional Capital Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.30% (the “Fee Limit”) through the later of (the “Termination Date”): (a) September 30, 2011; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund's Board of Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Capital Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Capital Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Capital Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$54
3 Years	$170
5 Years	$296
10 Years	$665

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury securities. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Counterparty Credit Risks. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

2Table Of Contents

• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance: Bar Chart and Table

Risk/Return Bar Chart

Fund Management

The Fund's Investment Adviser (“Adviser”) is Federated Investment Management Company.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Capital Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

4Table Of Contents

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to Treasury investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in Treasury investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the United States. U.S. Treasury securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the U.S. Treasury must repay the principal amount of the security, normally within a specified time. U.S. Treasury securities are generally regarded as having the lowest credit risks.

5Table Of Contents

Repurchase Agreements

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The

6Table Of Contents

larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set

7Table Of Contents

forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Capital Shares, Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Capital Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial

8Table Of Contents

intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

9Table Of Contents

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

11Table Of Contents

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

RETIREMENT INVESTMENTS

You may purchase Shares as retirement investments (such as qualified plans and IRAs or transfer or rollover of assets). Call your financial intermediary or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

12Table Of Contents

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds
30 Dan Road
Canton, MA 02021

• Fund Name and Share Class, account number and account registration;
• amount to be redeemed or exchanged;

• if exchanging, the Fund Name and Share Class, account number and account registration into which you are exchanging.

Call your financial intermediary or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed by a financial institution which is a participant in a Medallion signature guarantee program if:

• your redemption will be sent to an address other than the address of record;
• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or

13Table Of Contents

• transferring into another fund with a different shareholder registration.

A Medallion signature guarantee is designed to protect your account from fraud. Obtain a Medallion signature guarantee from a bank or trust company, savings association, credit union or broker, dealer or securities exchange member. Anotary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

14Table Of Contents

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions

15Table Of Contents

will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the

16Table Of Contents

Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

18Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$54
3 Years	$170
5 Years	$296
10 Years	$665

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury securities. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Counterparty Credit Risks. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net

2Table Of Contents

• purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance: Bar Chart and Table

Risk/Return Bar Chart

The performance information shown below will help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's Institutional Shares total returns on a calendar year-by-year basis.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

4Table Of Contents

The Fund invests primarily in a portfolio of U.S. Treasury securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to Treasury investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in Treasury investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the United States. U.S. Treasury securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted

5Table Of Contents

periodically. In addition, the U.S. Treasury must repay the principal amount of the security, normally within a specified time. U.S. Treasury securities are generally regarded as having the lowest credit risks.

Repurchase Agreements

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

6Table Of Contents

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined)

7Table Of Contents

will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Capital Shares, Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a

8Table Of Contents

company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor

9Table Of Contents

preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions

15Table Of Contents

will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the

16Table Of Contents

Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

18Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any) paid by the Fund's Institutional Service Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.45% (the “Fee Limit”) through the later of (the “Termination Date”): (a) September 30, 2011; or (b) the date of the Fund's next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated, or the Fee Limit increased, prior to the Termination Date with the agreement of the Fund's Board of Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

1Table Of Contents

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$54
3 Years	$170
5 Years	$296
10 Years	$665

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury securities. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Counterparty Credit Risks. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

2Table Of Contents

• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance: Bar Chart and Table

Risk/Return Bar Chart

Fund Management

The Fund's Investment Adviser (“Adviser”) is Federated Investment Management Company.

Purchase and Sale of Fund Shares

The required minimum initial investment amount for the Fund's Institutional Service Shares is $500,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

4Table Of Contents

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to Treasury investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in Treasury investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the United States. U.S. Treasury securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the U.S. Treasury must repay the principal amount of the security, normally within a specified time. U.S. Treasury securities are generally regarded as having the lowest credit risks.

5Table Of Contents

Repurchase Agreements

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The

6Table Of Contents

larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set

7Table Of Contents

forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Capital Shares, Institutional Shares, Institutional Service Shares and Trust Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial

8Table Of Contents

intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Submit your purchase order to your financial intermediary. Financial intermediaries are responsible for promptly submitting purchase orders and payment to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your order electronically, your order will be processed and you will be entitled to dividends pursuant to operating procedures established by the Fund. If your financial intermediary submits your order by telephone or by mail, your order will be processed and you will be entitled to dividends as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to purchase Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may purchase Shares by calling the Fund at 1-800-341-7400.

Your purchase will be priced at the NAV next calculated after the Fund receives your order. Receipt of a purchase order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders. If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m.) and send your payment by wire by the close of the Federal Reserve wire transfer system, you will be entitled to that day's dividend.

10Table Of Contents

Send your wire to:

State Street Bank and Trust Company
Boston, MA
Dollar Amount of Wire
ABA Number 011000028
BNF: 23026552
Attention: Federated EDGEWIRE
Wire Order Number, Dealer Number or Group Number
Nominee/Institution Name
Fund Name and Number and Account Number

If the Fund does not receive your purchase wire by the close of the Federal Reserve wire transfer system on the day you placed your order, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent.

You cannot purchase Shares by wire on days when wire transfers are restricted, even if the NYSE is open on such days (for example, Columbus Day and Veterans Day). The Fund does not consider wire purchase requests received on such days to be in proper form, and will not process such requests.

By Mail

You may purchase Shares by sending your check payable to The Federated Funds at the following address:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, send it to:

The Federated Funds
30 Dan Road
Canton, MA 02021

Please note your account number on your check. Payment should be made in U.S. dollars and drawn on a U.S. bank. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or State Street Bank and Trust Company, the Fund's transfer agent. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks) or involving temporary checks or credit card checks.

Your order will be priced at the NAV next calculated after the Fund receives your check and you will be entitled to dividends beginning on the day the check is converted into federal funds (normally the business day after the check is received).

11Table Of Contents

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable) and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

• through a financial intermediary if you purchased Shares through a financial intermediary; or
• directly from the Fund if you purchased Shares directly from the Fund.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary. Financial intermediaries are responsible for promptly submitting redemption or exchange requests to the Fund by electronic means permitted by the Fund, or according to the instructions in the sections “By Telephone” or “By Mail” below.

If your financial intermediary submits your redemption or exchange request electronically, your request will be processed and your proceeds will be paid pursuant to operating procedures established by the Fund. If your financial intermediary submits your redemption or exchange request by telephone or by mail, your request will be processed and your proceeds will be paid as outlined in the section “By Telephone” or the section “By Mail” below.

If you deal with a financial intermediary, you will have to follow the financial intermediary's procedures for transacting with the Fund. For more information about how to redeem or exchange Shares through your financial intermediary, you should contact your financial intermediary directly.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by calling the Fund at 1-800-341-7400. Your redemption or exchange request will be priced at the NAV next calculated after the request is received by the Fund. Receipt of a redemption or exchange order by a financial intermediary will be deemed received by the Fund to the extent that such financial intermediary has been duly authorized by the Fund to accept such orders.

12Table Of Contents

If you call the Fund by 5:00 p.m. Eastern time (or 3:00 p.m. Eastern time on those days when NAV is determined at 3:00 p.m. Eastern time), and your redemption proceeds are wired to you the same day, you will not be entitled to that day's dividend.

By Mail

You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption or exchange request will be priced at the NAV next calculated after the Fund receives your written request in proper form. If your redemption proceeds are wired to you the same day your order is priced, you will not be entitled to that day's dividend. If a check for your redemption proceeds is mailed to you on the next business day after your request is priced, you will be entitled to dividends through the day on which the Fund priced your request.

Send requests by mail to:

The Federated Funds
P.O. Box 8600
Boston, MA 02266-8600

• your redemption will be sent to an address of record that was changed within the last 30 days;
• a redemption is payable to someone other than the shareholder(s) of record; or
• transferring into another fund with a different shareholder registration.

13Table Of Contents

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

• an electronic transfer to your account at a financial institution that is an ACH member; or
• wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds will be wired or mailed within one business day after receiving a request in proper form, except that payment may be delayed in the following circumstances:

• to allow your purchase to clear (as discussed below);
• during any period when the Federal Reserve wire or Federal Reserve banks are closed (in which case redemption proceeds will be wired within one business day after the reopening of the Federal Reserve wire or Federal Reserve banks); or
• during any period when the NYSE is closed (in which case redemption proceeds will be wired within one business day after the reopening of the NYSE).

In addition, the Fund may suspend redemptions during any period in which there are emergency conditions, including liquidation of the Fund, as provided in Section 22(e), and the rules thereunder, of the Investment Company Act of 1940.

If you request a redemption of Shares recently purchased by check (including a cashier's check or certified check), money order, bank draft or ACH, your redemption proceeds may not be made available for up to seven calendar days to allow the Fund to collect payment on the instrument used to purchase such Shares. If the purchase instrument does not clear, your purchase order will be canceled and you will be responsible for any losses incurred by the Fund as a result of your canceled order.

You will not accrue interest or dividends on uncashed redemption checks from the Fund if those checks are undeliverable and returned to the Fund.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

14Table Of Contents

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming or exchanging Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption or exchange request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

15Table Of Contents

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

FREQUENT TRADING POLICIES

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

18Table Of Contents

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

Example

This Example is intended to help you compare the cost of investing in the Fund's Trust Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Trust Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Trust Shares operating expenses are as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests primarily in a portfolio of short-term U.S. Treasury securities. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities.
• Counterparty Credit Risks. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
• Risks Associated with Investing Share Purchase Proceeds. On days where there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the yield of the securities purchased is less than that of the securities already in the Fund's portfolio, or if the Fund holds cash, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. In the event of significant changes in short-term yields or significant net

2Table Of Contents

• purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.
• Risks Associated with use of Amortized Cost. In the unlikely event that the Fund's Board of Trustees (“Board”) were to determine pursuant to Rule 2a-7 that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.
• Changing Distribution Levels Risk. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation.

The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

Tax Information

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and/or its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

What are the Fund's Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this Prospectus.

The Fund invests primarily in a portfolio of U.S. Treasury securities maturing in 397 days or less. These investments include repurchase agreements collateralized fully by U.S. Treasury securities.

4Table Of Contents

The Fund's Adviser targets a dollar-weighted average portfolio maturity (DWAM) range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

• current U.S. economic activity and the economic outlook;
• current short-term interest rates;
• the Federal Reserve Board's policies regarding short-term interest rates; and
• the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's DWAM when it expects interest rates to rise and extends the DWAM when it expects interest rates to fall. This strategy seeks to enhance the returns from favorable interest rate changes and reduce the effect of unfavorable changes. The Adviser selects securities used to shorten or extend the portfolio's DWAM by comparing the returns currently offered by different investments to their historical and expected returns.

The Fund will: (1) maintain a DWAM of 60 days or less; and (2) maintain a weighted average life (WAL) of 120 days or less. Certain of the securities in which the Fund invests may pay interest at a rate that is periodically adjusted (“Adjustable Rate Securities”). For purposes of calculating DWAM, the maturity of an Adjustable Rate Security generally will be the period remaining until its next interest rate adjustment. For purposes of calculating WAL, the maturity of an Adjustable Rate Security will be its stated final maturity, without regard to interest rate adjustments; accordingly, the 120-day WAL limitation could serve to limit the Fund's ability to invest in Adjustable Rate Securities.

Because the Fund refers to Treasury investments in its name, the SEC requires the Fund to notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to normally invest less than 80% of its assets in Treasury investments.

What are the Principal Securities in Which the Fund Invests?

The following provides general information on the types of securities or other investments in which the Fund principally invests. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the securities and other investments in which the Fund principally invests as well.

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the United States. U.S. Treasury securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the U.S. Treasury must repay the principal amount of the security, normally within a specified time. U.S. Treasury securities are generally regarded as having the lowest credit risks.

5Table Of Contents

Repurchase Agreements

Repurchase agreements are transactions in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed-upon time and price. The repurchase price exceeds the sale price, reflecting the Fund's return on the transaction. This return is unrelated to the interest rate on the underlying security. The Fund will enter into repurchase agreements only with banks and other recognized financial institutions, such as securities dealers, deemed creditworthy by the Adviser.

The Fund's custodian or subcustodian will take possession of the securities subject to repurchase agreements. The Adviser or subcustodian will monitor the value of the underlying security each day to ensure that the value of the security always equals or exceeds the repurchase price.

Repurchase agreements are subject to credit risks.

What are the Specific Risks of Investing in the Fund?

The following provides general information on the risks associated with the types of securities and other investments in which the Fund principally invests. The Fund may invest in other types of securities or investments as non-principal investments. Any additional risks associated with investing in such other non-principal investments are described in the Fund's SAI. The Fund's SAI also may provide additional information about the risks associated with the types of securities in which the Fund principally invests.

INTEREST RATE RISK

Prices of fixed-income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

COUNTERPARTY CREDIT RISK

Counterparty credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

RISKS ASSOCIATED WITH INVESTING SHARE PURCHASE PROCEEDS

On days during which there are net purchases of Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund's yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will cause the Fund's yield to increase. The

6Table Of Contents

larger the amount that must be invested or the greater the difference between the yield of the securities purchased and the yield of the existing investments, the greater the impact will be on the yield of the Fund. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

RISKS ASSOCIATED WITH USE OF AMORTIZED COST

In the unlikely event that the Fund's Board were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund's amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce, to the extent practicable, such dilution or unfair results, including, but not limited to, considering suspending redemption of Shares and liquidating the Fund under Rule 22e-3 under the Investment Company Act of 1940.

changing distribution levels risk

There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund's yield will vary. A low interest rate environment may prevent the Fund from providing a positive yield or paying Fund expenses out of current income and could impair the Fund's ability to maintain a stable NAV.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. In addition, for regulatory purposes, the Fund calculates a market-based NAV per Share on a periodic basis. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge.

You can purchase, redeem or exchange Shares any day the New York Stock Exchange (NYSE) is open (a “Regular Business Day”). You may also be able to purchase and redeem (but not exchange) Shares on certain days that the NYSE is closed on an unscheduled basis due to unforeseen or emergency circumstances, if the Fund's Board determines to allow Fund Share transactions on such days (a “Special Trading Day”). If the Fund declares a Special Trading Day, information regarding shareholder trading activities for the Special Trading Day (such as when NAV, and entitlement to that day's dividend, will be determined) will be available by calling the Fund at 1-800-341-7400 and will be posted on Federated's website at FederatedInvestors.com. The information set forth in this Prospectus regarding times relevant to NAV determination and dividend entitlement applies only to Regular Business Days. Please note that the times that might be specified for NAV determination and dividend entitlement on a Special Trading Day would not necessarily be the same as set

7Table Of Contents

forth in this Prospectus with respect to Regular Business Days. Although Federated will attempt to make such information available in advance of a particular Special Trading Day, given the nature of Special Trading Days, it may not be able to do so until the morning of the Special Trading Day.

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next determined NAV. NAV is determined at 5:00 p.m. Eastern time each day the NYSE is open; except that on the day after Thanksgiving and Christmas Eve (when Christmas Eve falls on a weekday) NAV is determined at 3:00 p.m. Eastern time. The times as of when NAV is determined, and when orders must be placed, may be changed as permitted by the SEC.

How is the Fund Sold?

The Fund offers four Share classes: Institutional Capital Shares, Institutional Shares, Institutional Service Shares and Trust Shares , each representing interests in a single portfolio of securities. This Prospectus relates only to Trust Shares. All Share classes have different expenses which affect their performance. Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other classes.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to entities holding Shares in an agency or fiduciary capacity, financial institutions, financial intermediaries and institutional investors or to individuals, directly or through financial intermediaries. Under the Distributor's Contract with the Fund, the Distributor offers Shares on a continuous, best-efforts basis. The Distributor is a subsidiary of Federated Investors, Inc. (“Federated”).

Payments to Financial Intermediaries

The Fund and its affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Fund.

RULE 12b-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to0.25% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Trust Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

SERVICE FEES

The Fund may pay Service Fees of up to 0.25% of average net assets to financial intermediaries or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining

8Table Of Contents

shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on that same account.

ACCOUNT ADMINISTRATION FEES

The Fund may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account.

RECORDKEEPING FEES

The Fund may pay Recordkeeping Fees on an average-net-assets basis or on a per-account-per-year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account.

NETWORKING FEES

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account.

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to Fund shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Fund to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Adviser). These payments are not reflected in the fees and expenses listed in the fee table section of the Fund's Prospectus and described above because they are not paid by the Fund.

These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments of Rule 12b-1 Fees and/or Service Fees and/or Account Administration Fees and/or Recordkeeping Fees and/or Networking Fees made by the Fund to the financial intermediary. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary's organization by,

9Table Of Contents

for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided.

How to Purchase Shares

You may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund. The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

The required minimum initial investment for Fund Shares is $500,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $500,000 minimum is reached within one year. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

EXCHANGE PRIVILEGE

You may exchange Shares of the Fund for shares of any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. To do this, you must:

• ensure that the account registrations are identical;
• meet any applicable minimum initial investment requirements; and
• receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time.

Systematic Withdrawal/Exchange Program

You may automatically redeem or exchange Shares. Effective August 2, 2010, the minimum amount for all new or revised systematic redemptions or exchanges of Shares is $50 per transaction per fund.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including systematic transactions and dividends paid by the Fund.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders.

Dividends are based on estimates of income, expenses and shareholder activity for the Fund. Actual income, expenses and shareholder activity may differ from estimates and differences, if any, will be included in the calculation of subsequent dividends. You may obtain an estimate of the Fund's daily dividend factor by calling the Fund at 1-800-341-7400 or on Federated's website at FederatedInvestors.com.

From time to time, the Fund may realize capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually, and may make such special distributions of dividends and capital gains as may be necessary to meet applicable regulatory requirements. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments. Dividends may also be reinvested without sales charges in shares of any class of any other Federated fund of which you are already a shareholder.

If you have elected to receive dividends and/or capital gain distributions in cash, and your check is returned by the postal or other delivery service as “undeliverable,” or you do not respond to mailings from Federated with regard to uncashed distribution checks, your distribution option will automatically be converted to having all dividends and capital gains reinvested in additional Shares. No interest will accrue on amounts represented by uncashed distribution checks.

Important information regarding the Fund's distributions, including the percentage of the Fund's distributions that are attributable to capital gains during the calendar year (if any), is available in the “Products” section of Federated's website at FederatedInvestors.com by clicking on the “Tax Center” link under “Related Information” and then clicking on “Year-End Tax Statements.”

ACCOUNTS WITH LOW BALANCES

Federated reserves the right to close accounts if redemptions or exchanges cause the account balance to fall below $500,000. Before an account is closed, you will be notified and allowed at least 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an IRS Form 1099 and an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in

16Table Of Contents

cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Distributions of net short-term capital gains are taxable to you as ordinary income. Distributions of net long-term capital gains are taxable to you as long-term capital gains regardless of how long you have owned your Shares.

Fund distributions are expected to be primarily dividends. Redemptions and exchanges are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

Given the short-term nature of the Fund's investments and its use of the amortized cost method for calculating the NAV of Fund Shares, the Fund does not anticipate that in the normal case frequent or short-term trading into and out of the Fund will have significant adverse consequences for the Fund and its shareholders. For this reason and because the Fund is intended to be used as a liquid short-term investment, the Fund's Board has not adopted policies or procedures to monitor or discourage frequent or short-term trading of the Fund's Shares. Regardless of their frequency or short-term nature, purchases and redemptions of Fund Shares can have adverse effects on the management of the Fund's portfolio and its performance.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund's assets, including buying and selling portfolio securities. Federated Advisory Services Company (FASC), an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

The address of the Adviser and FASC is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 145 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles and customized, separately managed accounts, which totaled approximately $389 billion in assets as of December 31, 2009. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,370 employees. Federated provides investment products to over 5,200 investment professionals and institutions.

The Adviser advises approximately 101 fixed-income and money market mutual funds as well as a variety of customized, separately managed accounts, which totaled approximately $287.2 billion in assets as of December 31, 2009.

ADVISORY FEES

The Fund's investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.20% of the Fund's average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's Annual Report dated July 31, 2010.

Legal Proceedings

Since October 2003, Federated and related entities (collectively, “Federated”) and various Federated-sponsored mutual funds (“Funds”) have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of certain Funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. Federated without admitting the validity of any claim has reached a preliminary settlement with the Plaintiffs in these cases. Any settlement would have to be approved by the Court.

Federated entities have also been named as defendants in several additional lawsuits that are now pending in the United States District Court for the Western District of Pennsylvania. These lawsuits have been consolidated into a single action alleging excessive advisory fees involving one of the Funds.

The Board of the Funds retained the law firm of Dickstein Shapiro LLP to represent the Funds in each of the lawsuits described in the preceding two paragraphs. Federated and the Funds, and their respective counsel, have been defending this litigation, and none of the Funds remains a defendant in any of the lawsuits. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek monetary damages, attorneys' fees and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the allegations in these matters will not result in increased redemptions, or reduced sales, of shares of the Funds or other adverse consequences for the Funds.

Appendix A: Hypothetical Investment and Expense Information

The following chart provides additional hypothetical information about the effect of the Fund's expenses, including investment advisory fees and other Fund costs, on the Fund's assumed returns over a 10-year period. The chart shows the estimated expenses that would be incurred in respect of a hypothetical investment of $10,000, assuming a 5% return each year, and no redemption of Shares. The chart also assumes that the Fund's annual expense ratio stays the same throughout the 10-year period and that all dividends and distributions are reinvested. The annual expense ratio used in the chart is the same as stated in the “Fees and Expenses” table of this Prospectus (and thus may not reflect any fee waiver or expense reimbursement currently in effect). The maximum amount of any sales charge that might be imposed on the purchase of Shares (and deducted from the hypothetical initial investment of $10,000; the “Front-End Sales Charge”) is reflected in the “Hypothetical Expenses” column. The hypothetical investment information does not reflect the effect of charges (if any) normally applicable to redemptions of Shares (e.g., deferred sales charges, redemption fees). Mutual fund returns, as well as fees and expenses, may fluctuate over time, and your actual investment returns and total expenses may be higher or lower than those shown below.

How is the Fund Organized?

The Fund is a diversified portfolio of Money Market Obligations Trust (“Trust”). The Trust is an open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on October 3, 1988. The Fund was organized as a portfolio of the Trust on December 11, 1989. The Trust may offer separate series of shares representing interests in separate portfolios of securities. The Fund changed its name from Treasury Obligations Fund to Federated Treasury Obligations Fund on June 30, 2010.

The Board of Trustees (“Board”) has established four classes of shares of the Fund, known as Institutional Shares, Institutional Service Shares, Institutional Capital Shares and Trust Shares (“Shares”). This SAI relates to all classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities in Which the Fund Invests

The principal securities or other investments in which the Fund invests are described in the Fund’s Prospectus. The Fund also may invest in securities or other investments as non-principal investments for any purpose that is consistent with its investment objective. The following information is either additional information in respect of a principal security or other investment referenced in the Prospectus or information in respect of a non-principal security or other investment (in which case there is no related disclosure in the Prospectus).

Securities Descriptions And Techniques

Zero-Coupon Securities (A Fixed-Income Security)

Certain U.S. Treasury securities in which the Fund invests may be zero coupon securities. Zero coupon securities do not pay interest or principal until final maturity, unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero coupon security.

Callable Securities (A Fixed-Income Security)

Certain U.S. Treasury securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

Other Investments, Transactions, Techniques

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (“Federated funds”) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending Federated funds, and an inter-fund loan is only made if it benefits each participating Federated fund. Federated Investors, Inc. (“Federated”) administers the program according to procedures approved by the Fund’s Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating Federated funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; (b) to meet commitments arising from “failed” trades; and (c) for other temporary purposes. All inter-fund loans must be repaid in seven days or less. The Fund’s participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending Federated fund than market-competitive rates on overnight repurchase agreements (“Repo Rate”) and more attractive to the borrowing Federated fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (“Bank Loan Rate”), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

1Table Of Contents

Delayed Delivery Transactions

Delayed delivery transactions, including when issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Segregation

In order to secure its obligations in connection with special transactions, the Fund will either enter into offsetting transactions or set aside readily marketable securities. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

Investment Risks

There are many risk factors which may affect an investment in the Fund. The Fund’s principal risks are described in its Prospectus. The following information is either additional information in respect of a principal risk factor referenced in the Prospectus or information in respect of an additional risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

Call Risks

Call risk is the possibility that an issuer may redeem a fixed-income security before maturity (a “call”) at a price below its current market price. An increase in the likelihood of a call may reduce the security’s price.

If a fixed-income security is called, the Fund may have to reinvest the proceeds in other fixed-income securities with lower interest rates, higher credit risks or other less favorable characteristics.

Risks Associated with the Investment Activities of Other Accounts

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. Therefore, it is possible that investment-related actions taken by such other accounts could adversely impact the Fund with respect to, for example, the value of Fund portfolio holdings, and/or prices paid to or received by the Fund on its portfolio transactions, and/or the Fund’s ability to obtain or dispose of portfolio securities. Related considerations are discussed elsewhere in this SAI under “Brokerage Transactions and Investment Allocation.”

Investment Objective and Investment Limitations

The Fund’s investment objective is to provide current income consistent with stability of principal. The investment objective may not be changed by the Board without shareholder approval.

Investment Limitations

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (“1940 Act”).

2Table Of Contents

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Underwriting

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Lending

The Fund may not make loans, provided that this restriction does not prevent the Fund from purchasing debt obligations, entering into repurchase agreements, lending its assets to broker/dealers or institutional investors and investing in loans, including assignments and participation interests.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

The above limitations cannot be changed unless authorized by the Board and by the “vote of a majority of its outstanding voting securities,” as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided that this shall not apply to the transfer of securities in connection with any permissible borrowing or to collateral arrangements in connection with permissible activities.

Purchases on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Illiquid Securities

The Fund will not acquire securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in such securities.

Restricted Securities

The Fund may invest in securities subject to restriction on resale under the federal securities laws.

Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.”

For purposes of the concentration limitation, to conform to the current view of the SEC that only domestic bank instruments may be excluded from industry concentration limitations, the Fund will not exclude foreign bank instruments from industry concentration limits as long as the policy of the SEC remains in effect. As a non-fundamental operating policy, the Fund will consider concentration to be the investment of more than 25% of the value of its total assets in any one industry.

3Table Of Contents

For purposes of the concentration limitation: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the Prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the “Rule”), which regulates money market mutual funds. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

What Do Shares Cost?

Determining Market Value Of Securities

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with generally accepted accounting principles in the United States (GAAP). The Fund then adjusts the amount of interest income accrued each day over the term of the investment to account for any difference between the initial cost of their investment and the amount payable at its maturity. If the amount payable at maturity exceeds the initial cost (a “discount”), then the daily accrual is increased; if the initial cost exceeds the amount payable at maturity (a “premium”), then the daily accrual is decreased. The Fund adds the amount of the increase to (in the case of a discount), or subtracts the amount of the decrease from (in the case of a premium), the investment’s cost each day. The Fund uses this adjusted cost to value the investment.

Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund, computed by dividing the annualized daily income on the Fund’s portfolio by the NAV, computed as above, may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund’s use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund’s investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in-kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor’s Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

Rule 12b-1 Plan (Trust Shares)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor for activities principally intended to result in the sale of Shares such as advertising and marketing of Shares (including printing and distributing Prospectuses and sales literature to prospective shareholders and financial intermediaries) and providing incentives to financial intermediaries to sell Shares. The Plan is also designed to cover the cost of administrative services performed in conjunction with the sale of Shares, including, but not limited to, shareholder services, recordkeeping services and educational services, as well as the costs of implementing and operating the Plan. The Rule 12b-1 Plan allows the Distributor to contract with financial intermediaries to perform activities covered by the Plan. The Rule 12b-1 Plan is expected to benefit the Fund in a number of ways. For example, it is anticipated that the Plan will help the Fund attract and retain assets, thus providing cash for orderly portfolio management and Share redemptions and possibly helping to stabilize or reduce other operating expenses.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

4Table Of Contents

The maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

Additional Payments To Financial Intermediaries

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Fund and/or other Federated funds within the financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary’s organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Federated funds and any services provided.

The following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

The Distributor may make supplemental payments to certain financial intermediaries that are holders or dealers of record for accounts in one or more of the Federated funds. These payments may be based on such factors as: the number or value of Shares the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary.

Processing Support Payments

The Distributor may make payments to financial intermediaries that sell Federated fund shares to help offset their costs associated with client account maintenance support, statement processing and transaction processing. The types of payments that the Distributor may make under this category include: payment of ticket charges on a per-transaction basis; payment of networking fees; and payment for ancillary services such as setting up funds on the financial intermediary’s mutual fund trading system.

Retirement Plan Program Servicing Payments

The Distributor may make payments to certain financial intermediaries who sell Federated fund shares through retirement plan programs. A financial intermediary may perform retirement plan program services itself or may arrange with a third party to perform retirement plan program services. In addition to participant recordkeeping, reporting or transaction processing, retirement plan program services may include: services rendered to a plan in connection with fund/investment selection and monitoring; employee enrollment and education; plan balance rollover or separation; or other similar services.

Other Benefits to Financial Intermediaries

From time to time, the Distributor, at its expense, may provide additional compensation to financial intermediaries that sell or arrange for the sale of Shares. Such compensation may include financial assistance to financial intermediaries that enable the Distributor to participate in or present at conferences or seminars, sales or training programs for invited employees, client and investor events and other financial intermediary-sponsored events.

The Distributor also may hold or sponsor, at its expense, sales events, conferences and programs for employees or associated persons of financial intermediaries and may pay the travel and lodging expenses of attendees. The Distributor also may provide, at its expense, meals and entertainment in conjunction with meetings with financial intermediaries. Other compensation may be offered to the extent not prohibited by applicable laws, regulations or the rules of any self-regulatory agency, such as FINRA.

Purchases In-Kind

You may contact the Distributor to request a purchase of Shares using securities you own. The Fund reserves the right to determine whether to accept your securities and the minimum market value to accept. The Fund will value your securities in the same manner as it values its assets in determining the market value of the portfolio for purposes of its comparison with amortized cost valuation. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

Certain financial intermediaries may wish to use the transfer agent’s subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Financial intermediaries holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the financial intermediary about the services provided, the fees charged for those services and any restrictions and limitations imposed.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust’s obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Federal Income Tax

The Fund intends to meet requirements of Subchapter M of the Internal Revenue Code (“Code”) applicable to regulated investment companies. If these requirements are not met, it will not receive special tax treatment and will be subject to federal corporate income tax.

The Fund will be treated as a single, separate entity for federal income tax purposes so that income earned and capital gains and losses realized by the Trust’s other portfolios will be separate from those realized by the Fund.

Investment Adviser

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence or reckless disregard of the duties imposed upon it by its contract with the Trust.

12Table Of Contents

Services Agreement

Federated Advisory Services Company, an affiliate of the Adviser, provides certain support services to the Adviser. The fee for these services is paid by the Adviser and not by the Fund.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

Code Of Ethics Restrictions On Personal Trading

As required by SEC rules, the Fund, its Adviser and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, as well as Shares of the Fund, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

Voting Proxies On Fund Portfolio Securities

The Board has delegated to the Adviser authority to vote proxies on the securities held in the Fund’s portfolio. The Board has also approved the Adviser’s policies and procedures for voting the proxies, which are described below.

Proxy Voting Policies

The Adviser’s general policy is to cast proxy votes in favor of proposals that the Adviser anticipates will enhance the long-term value of the securities being voted. Generally, this will mean voting for proposals that the Adviser believes will: improve the management of a company; increase the rights or preferences of the voted securities; and/or increase the chance that a premium offer would be made for the company or for the voted securities.

The following examples illustrate how these general policies may apply to proposals submitted by a company’s board of directors. However, whether the Adviser supports or opposes a proposal will always depend on the specific circumstances described in the proxy statement and other available information.

On matters of corporate governance, generally the Adviser will vote for the full slate of directors nominated in an uncontested election; and for proposals to: require a company’s audit committee to be comprised entirely of independent directors; require independent tabulation of proxies and/or confidential voting by shareholders; reorganize in another jurisdiction (unless it would reduce the rights or preferences of the securities being voted); ratify the board’s selection of auditors (unless compensation for non-audit services exceeded 50% of the total compensation received from the company, or the previous auditor was dismissed because of a disagreement with the company); and repeal a shareholder rights plan (also known as a “poison pill”). The Adviser will generally vote against the adoption of such a plan (unless the plan is designed to facilitate, rather than prevent, unsolicited offers for the company).

On matters of capital structure, generally the Adviser will vote: against proposals to authorize or issue shares that are senior in priority or voting rights to the securities being voted; and for proposals to: reduce the amount of shares authorized for issuance; authorize a stock repurchase program; and grant preemptive rights to the securities being voted. The Adviser will generally vote against proposals to eliminate such preemptive rights.

On matters relating to management compensation, generally the Adviser will vote: for stock incentive plans that align the recipients’ interests with the interests of shareholders without creating undue dilution; against proposals that would permit the amendment or replacement of outstanding stock incentives with new stock incentives having more favorable terms; and against executive compensation plans that do not disclose the maximum amounts of compensation that may be awarded or the criteria for determining awards.

On matters relating to corporate transactions, the Adviser will vote proxies relating to proposed mergers, capital reorganizations and similar transactions in accordance with the general policy, based upon its analysis of the proposed transaction. The Adviser will vote proxies in contested elections of directors in accordance with the general policy, based upon its analysis of the opposing slates and their respective proposed business strategies. Some transactions may also involve proposed changes to the company’s corporate governance, capital structure or management compensation. The Adviser will vote on such changes based on its evaluation of the proposed transaction or contested election. In these circumstances, the Adviser may vote in a manner contrary to the general practice for similar proposals made outside the context of such a proposed transaction or change in the board. For example, if the Adviser decides to vote against a proposed transaction, it may vote for anti-takeover measures reasonably designed to prevent the transaction, even though the Adviser typically votes against such measures in other contexts.

The Adviser generally votes against proposals submitted by shareholders without the favorable recommendation of a company’s board. The Adviser believes that a company’s board should manage its business and policies, and that shareholders who seek specific changes should strive to convince the board of their merits or seek direct representation on the board.

13Table Of Contents

In addition, the Adviser will not vote if it determines that the consequences or costs outweigh the potential benefit of voting. For example, if a foreign market requires shareholders casting proxies to retain the voted shares until the meeting date (thereby rendering the shares “illiquid” for some period of time), the Adviser will not vote proxies for such shares.

Proxy Voting Procedures

The Adviser has established a Proxy Voting Committee (“Proxy Committee”), to exercise all voting discretion granted to the Adviser by the Board in accordance with the proxy voting policies. The Adviser has hired Glass Lewis & Co. (GL) to obtain, vote and record proxies in accordance with the Proxy Committee’s directions. The Proxy Committee has supplied GL with general voting instructions that represent decisions made by the Proxy Committee in order to vote common proxy proposals; however, the Proxy Committee retains the right to modify these voting instructions at any time or to vote contrary to the voting instructions at any time in order to cast proxy votes in a manner that the Proxy Committee believes is consistent with the Adviser’s general policy. GL may vote any proxy as directed in the voting instructions without further direction from the Proxy Committee and may make any determinations required to implement the voting instructions. However, if the voting instructions require case-by-case direction for a proposal, GL shall provide the Proxy Committee with all information that it has obtained regarding the proposal and the Proxy Committee will provide specific direction to GL.

Conflicts of Interest

The Adviser has adopted procedures to address situations where a matter on which a proxy is sought may present a potential conflict between the interests of the Fund (and its shareholders) and those of the Adviser or Distributor. This may occur where a significant business relationship exists between the Adviser (or its affiliates) and a company involved with a proxy vote. A company that is a proponent, opponent or the subject of a proxy vote, and which to the knowledge of the Proxy Committee has this type of significant business relationship, is referred to as an “Interested Company.”

The Adviser has implemented the following procedures in order to avoid concerns that the conflicting interests of the Adviser have influenced proxy votes. Any employee of the Adviser who is contacted by an Interested Company regarding proxies to be voted by the Adviser must refer the Interested Company to a member of the Proxy Committee, and must inform the Interested Company that the Proxy Committee has exclusive authority to determine how the Adviser will vote. Any Proxy Committee member contacted by an Interested Company must report it to the full Proxy Committee and provide a written summary of the communication. Under no circumstances will the Proxy Committee or any member of the Proxy Committee make a commitment to an Interested Company regarding the voting of proxies or disclose to an Interested Company how the Proxy Committee has directed such proxies to be voted. If the voting instructions already provide specific direction on the proposal in question, the Proxy Committee shall not alter or amend such directions. If the voting instructions require the Proxy Committee to provide further direction, the Proxy Committee shall do so in accordance with the proxy voting policies, without regard for the interests of the Adviser with respect to the Interested Company. If the Proxy Committee provides any direction as to the voting of proxies relating to a proposal affecting an Interested Company, it must disclose to the Fund’s Board information regarding: the significant business relationship; any material communication with the Interested Company; the matter(s) voted on; and how, and why, the Adviser voted as it did. Alternatively, the Proxy Committee may seek direction from the Fund’s Board on how a proposal concerning an Interested Company shall be voted, and shall follow any such direction provided by the Board. In seeking such direction, the Proxy Committee will disclose the reason such company is considered an Interested Company and may provide a recommendation on how such proposal should be voted and the basis for such recommendation.

If the Fund holds shares of another investment company for which the Adviser (or an affiliate) acts as an investment adviser, the Proxy Committee will vote the Fund’s proxies in the same proportion as the votes cast by shareholders who are not clients of the Adviser at any shareholders’ meeting called by such investment company, unless otherwise directed by the Board.

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

14Table Of Contents

portfolio composition information as of the close of each month is posted on the website 15 days (or the next business day) after month-end and remains until replaced by the information for the succeeding month.

To access this information from the “Products” section of the website, click on the “Portfolio Holdings” link under “Related Information” and select the appropriate link opposite the name of the Fund, or select the name of the Fund, and from the Fund’s page, click on the “Portfolio Holdings” or “Composition” link.

You may also access portfolio information as of the end of the Fund’s fiscal quarters from the “Products” section of the website. The Fund’s Annual and Semi-Annual Reports, which contain complete listings of the Fund’s portfolio holdings as of the end of the Fund’s second and fourth fiscal quarters, may be accessed by selecting the “Prospectuses and Regulatory Reports” link under “Related Information” and selecting the link to the appropriate PDF. Complete listings of the Fund’s portfolio holdings as of the end of the Fund’s first and third fiscal quarters may be accessed by selecting “Portfolio Holdings” from the “Products” section and then selecting the appropriate link opposite the name of the Fund. Fiscal quarter information is made available on the website within 70 days after the end of the fiscal quarter. This information is also available in reports filed with the SEC at the SEC’s website at www.sec.gov.

The disclosure policy of the Fund and the Adviser prohibits the disclosure of portfolio holdings information to any investor or intermediary before the same information is made available to other investors. Employees of the Adviser or its affiliates who have access to nonpublic information concerning the Fund’s portfolio holdings are prohibited from trading securities on the basis of this information. Such persons must report all personal securities trades and obtain pre-clearance for all personal securities trades other than mutual fund shares.

Brokerage Transactions And Investment Allocation

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. Fixed-income securities are generally traded in an over-the-counter market on a net basis (i.e., without commission) through dealers acting as principal or in transactions directly with the issuer. Dealers derive an undisclosed amount of compensation by offering securities at a higher price than they bid for them. Some fixed-income securities may have only one primary market maker. The Adviser seeks to use dealers it believes to be actively and effectively trading the security being purchased or sold, but may not always obtain the lowest purchase price or highest sale price with respect to a security. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser and accounts managed by affiliates of the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund. Investment decisions and trading for certain separately managed or wrap-fee accounts, and other accounts, of the Adviser and/or certain investment adviser affiliates of the Adviser are generally made and conducted independently from the Fund. It is possible that such independent trading activity could adversely impact the prices paid or received and/or positions obtained or disposed of by the Fund.

Administrator

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC’s standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund’s or any class of Shares’ expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

Average Annual Total Returns and Yield

Total returns are given for the one-year, five-year and ten-year or Start of Performance periods ended July 31, 2010.

Yield, Effective Yield and Tax-Equivalent Yield are given for the seven-day period ended July 31, 2010.

Total Return

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions.

Yield And Effective Yield

The yield of Shares is based upon the seven days ending on the day of the calculation, called the “base period.” This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account’s value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base period return by: adding one to the base period return; raising the sum to the 365/7th power; and subtracting one from the result.
