INSTITUTIONAL SERVICE SHARES (TICKER AGSXX)
(Effective September 30, 2011, the Fund's Institutional Service Shares will be redesignated as Service Shares)

A money market mutual fund seeking current income with stability of principal and liquidity by investing only in a portfolio of short-term U.S. Treasury and government securities.

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.

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per Share. The Fund's investment objective is current income with stability of principal and liquidity.

This table describes the fees and expenses that you may pay if you buy and hold Institutional Service Shares (SS) of the Fund.

The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses paid by the Fund's SS class (after the voluntary waivers and/or reimbursements) will not exceed 0.59% (the “Fee Limit”) up to but not including the later of (the “Termination Date”): (a) July 1, 2012; 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.

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

The Example assumes that you invest $10,000 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 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:

The Fund invests only 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”).

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:

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 bar chart and performance table below reflect historical performance data for the Fund and are intended to help you analyze the Fund's investment risks in light of its historical returns. The bar chart shows the variability of the Fund's SS class total returns on a calendar year-by-year basis. The Average Annual Total Return Table shows returns averaged over the stated periods, and includes comparative performance information. The Fund's performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication of future results. Updated performance information for the Fund is available under the “Products” section at FederatedInvestors.com or by calling the Fund at 1-800-341-7400.

The Fund's SS class total return for the three-month period from January 1, 2011 to March 31, 2011, was 0.00%.

Within the period shown in the bar chart, the Fund's SS class highest quarterly return was 1.30% (quarter ended March 31, 2001). Its lowest quarterly return was 0.00% (quarter ended March 31, 2010).

The following table represents the Fund's Average Annual Total Returns for the calendar periods ended December 31, 2010.

The Fund's Institutional Service Shares 7-Day Net Yield as of December 31, 2010, was 0.01%. You may call the Fund at 1-800-341-7400 for the current 7-Day Net Yield.

The Fund's Investment Adviser (“Adviser”) is Federated Investment Management Company.

The minimum initial investment amount for the Fund's Institutional Service Shares is generally $25,000 and there is no minimum subsequent investment amount. There is no minimum initial or subsequent investment amount required for employer-sponsored retirement plans.

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. Please note that certain purchase restrictions may apply. Redeem or exchange Shares through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

The Fund's distributions are taxable as ordinary income or capital gains except when your investment is through a 401(k) plan, an Individual Retirement Account (IRA) or other tax-advantaged investment plan.

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.

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'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:

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 invest less than 80% of its assets in government investments.

The following provides general information on the Fund's principal investments. The Fund's Statement of Additional Information (SAI) provides information about the Fund's non-principal investments and may provide additional information about the Fund's principal investments.

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.

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

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 U.S. Treasury securities.

Certain U.S. Treasury or government securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks.

The following provides general information on the risks associated with the Fund's principal investments. Any additional risks associated with the Fund's 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 Fund's principal investments.

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 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 risk is the possibility that an issuer may redeem a U.S. 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 U.S. 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.

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.

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.

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.

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.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to institutional investors, such as corporations, unions, hospitals, insurance companies and municipalities 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”).

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.

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.

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 Fund and its 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.

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 Fund and its 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.

The Fund may reimburse Networking Fees on a per-account-per-year basis to financial intermediaries for providing administrative services to the Fund and its 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.

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, as described above, 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.

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

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.

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 2:00 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.

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.

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

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

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).

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 R class. You must meet the minimum initial investment requirement for purchasing Shares (if applicable), and both accounts must have identical registrations.

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.

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.

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.

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.

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

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.

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:

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.

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:

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:

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

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 R class. To do this, you must:

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.

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.

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.

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.

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.

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

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. To access this information from the homepage, select “View All” next to “Find Products.” Select the Fund name and share class, if applicable, to go to the Fund Overview page. On the Fund Overview page, select the “Tax Information” tab. On the “Tax Information” tab, select a year.

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.

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.

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.

Other funds in the Federated family of funds may impose different monitoring policies or in some cases, may not monitor for frequent or short-term trading. Under normal market conditions, such monitoring policies are designed to protect the funds being monitored and their shareholders, and the operation of such policies and shareholder investments under such monitoring are not expected to have materially adverse impact on the Federated funds or their shareholders. If you plan to exchange your fund shares for shares of another Federated fund, please read the prospectus of that other Federated fund for more information.

Information concerning the Fund's portfolio holdings as of the end of each month, as well as the Fund's DWAM and WAL, is available in the “Products” section of Federated's website at FederatedInvestors.com. Such information is posted on the website five business days after the end of the month and remains posted on the website for at least a year. 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 for at least a year. The summary portfolio composition information may include 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's home page, select “View All” next to “Find Products.” Select the Fund name and share class, if applicable, to go to the Fund Overview page. On the Fund Overview page, select the “Portfolio Characteristics” tab for summary portfolio information or the “Documents” tab to access “Holdings.”

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.

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 136 equity, fixed-income and money market mutual funds as well as a variety of other pooled investment vehicles, private investment companies, and customized separately managed accounts (including non-U.S./offshore funds) which totaled approximately $358.2 billion in assets as of December 31, 2010. Federated was established in 1955 and is one of the largest investment managers in the United States with approximately 1,334 employees. Federated provides investment products to approximately 5,000 investment professionals and institutions.

The Adviser advises approximately 111 fixed-income and money market mutual funds (including sub-advised funds) and private investment companies, which totaled approximately $259.5 billion in assets as of December 31, 2010.

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. The Adviser and its affiliates have also agreed to certain “Fee Limits” as described in the footnote to the “Risk/Return Summary: Fees and Expenses” table found in the “Fund Summary” section of the Prospectus.

A discussion of the Board's review of the Fund's investment advisory contract is available in the Fund's shareholder reports as they are produced.

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.

Further information about the Fund's performance is contained in the Fund's Annual Report, dated April 30, 2010, which can be obtained free of charge.

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 minimum initial investment amount for the Fund's Institutional Shares is generally $25,000 and there is no minimum subsequent investment amount. There is no minimum initial or subsequent investment amount required for employer-sponsored retirement plans.

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.

Because the Fund refers to U.S. 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 invest less than 80% of its assets in U.S. Treasury investments.

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.

Prices of U.S. Treasury securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of U.S. Treasury securities fall.

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

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.

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.

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. Effective September 30, 2011, the Fund's Institutional Service Shares will be redesignated as Service Shares. 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.

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.

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.
