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, Service Shares and Capital Shares (“Shares”). Effective September 30, 2011, the Fund's Institutional Service Shares were redesignated as Service Shares and the Fund's Institutional Capital Shares were redesignated as Capital 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, 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 helps protect against credit risk, it does not eliminate it entirely or 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, downgrades or upgrades in the credit ratings assigned to Freddie Mac and Fannie Mae by nationally recognized statistical rating organization (NRSROs) or ratings services, 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 (MBS) (A Fixed-Income Security)

An MBS is a type of pass-through security, which is a pooled debt obligation repackaged as interests that pass principal and interest through an intermediary to investors. In the case of MBS, the ownership interest is issued by a trust and represents participation interests in pools of adjustable and fixed-rate mortgage loans. MBS are most commonly issued or guaranteed by the U.S. government (or one of its agencies or instrumentalities) (“agency MBS”), but also may be issued or guaranteed by private entities (“non-agency MBS”). Unlike conventional debt obligations, MBS provide monthly payments derived from the monthly interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans. Most MBS make these payments monthly; however, certain MBS are backed by mortgage loans which do not generate monthly payments but rather generate payments less frequently.

The mortgage loan collateral for non-agency MBS consists of residential mortgage loans that do not conform to GSEs underwriting guidelines. Non-agency MBS generally offer a higher yield than agency MBS because there are no direct or indirect government guarantees of payment.

Investments in MBS expose the Fund to interest rate, prepayment and credit risks.

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

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 a non-principal risk factor applicable to the Fund (in which case there is no related disclosure in the Prospectus).

leverage Risk

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 Risk

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.

Risk 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.”

Risk 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 Trustees 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.

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 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.

Additional Information

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.

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.

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.

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 4, 2012, the Fund's Board and Officers as a group owned less than 1% of each class of the Fund's outstanding Shares.

Executive	John F. Donahue Peter E. Madden John S.

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.

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.”

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; from the home page, select “All” under “Asset Classes”; select the Fund name and share class, if applicable, to go to the Fund Overview page; on the Fund Overview page, select the “Documents” tab; at the bottom of that page, select “Proxy Voting Record Report (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 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 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 holdings and percentage breakdowns of the portfolio by credit tier, type of security and effective maturity range.

To access this information from the “Products” section of the website's home page, select “All” under “Asset Classes.” 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.”

You may also access portfolio information as of the end of the Fund's fiscal quarters from the “Documents” tab. The Fund's Annual Shareholder Report and Semi-Annual Shareholder Report contain complete listings of the Fund's portfolio holdings as of the end of the Fund's second and fourth fiscal quarters. The Fund's Form N-Q filings contain complete listings of the Fund's portfolio holdings as of the end of the Fund's first and third fiscal quarters. 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.

On any business day, you may submit a request to receive an uncertified and unaudited list of the Fund's portfolio holdings as of the prior business day by calling Federated at 1-800-245-4270. The Fund will treat any such request as a standing request, and will transmit such list to you on each business day, on an ongoing basis, until you call Federated at 1-800-245-4270 to terminate such request. Given the general availability of such list, for purposes of its policies and procedures, the Fund considers the information contained therein to be publicly available. The Adviser reserves the right to refuse to fulfill any request for portfolio holdings information if it believes that providing such information may adversely affect the Fund or its shareholders. The identities of those persons or entities who have received such list during a calendar quarter will be included in Appendix B to this SAI following the close of every calendar quarter.

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 Appendix A 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.

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

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.

REGULATORY COMPLIANCE

What Do Shares Cost?

Determining Market Value Of Securities

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.

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.

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.

For some classes of Shares 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 following examples illustrate the types of instances in which the Distributor may make additional payments to financial intermediaries.

Supplemental Payments

Processing Support Payments

Retirement Plan Program Servicing Payments

Other Benefits to Financial Intermediaries

Purchases In-Kind

Subaccounting Services

Massachusetts Partnership Law

Proxy Voting Procedures

Conflicts of Interest

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.

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, Service Shares and Capital Shares (“Shares”). Effective September 30, 2011, the Fund's Institutional Service Shares were redesignated as Service Shares and the Fund's Institutional Capital Shares were redesignated as Capital 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

Securities Descriptions And Techniques

Government Securities (A Fixed-Income Security)

Zero-Coupon Securities (A Fixed-Income 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 (MBS) (A Fixed-Income Security)

Investments in MBS expose the Fund to interest rate, prepayment and credit risks.

Bank Instruments (A Fixed-Income Security)

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)

Other Investments, Transactions, Techniques

Reverse Repurchase Agreements

Delayed Delivery Transactions

Securities Lending

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.

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

Asset Segregation

Inter-Fund Borrowing and Lending Arrangements

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.

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.
