Federated Adjustable Rate Securities Fund

PROSPECTUS

October 31, 2010

INSTITUTIONAL SHARES (TICKER FEUGX)

A mutual fund seeking to provide current income consistent with minimal volatility of principal by investing primarily in adjustable- and floating-rate 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.

Fund Summary Information

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

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

RISK/RETURN SUMMARY: FEES AND EXPENSES

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

Shareholder Fees
Fees Paid Directly From Your Investment
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, as applicable)	None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends (and other Distributions) (as a percentage of offering price)	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None
Exchange Fee	None
Annual Fund Operating Expenses
Expenses That You Pay Each Year as a Percentage of the Value of Your Investment
Management Fee	0.60%
Distribution (12b-1) Fee	None
Other Expenses	0.41%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	1.02%
Fee Waivers and/or Expense Reimbursements1	0.37%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.65%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses) paid by the Fund’s Institutional Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.64% (the “Fee Limit”) through the later of (the “Termination Date”): (a) October 31, 2011; or (b) the date of the Fund’s next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund’s Board of Trustees.

Example

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

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

1 Year	$104
3 Years	$325
5 Years	$563
10 Years	$1,248

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). Dollar-roll transactions and prepayments of mortgage-backed securities will cause the Fund to have an increased portfolio turnover rate which is likely to generate shorter-term gains (losses) for its shareholders. Portfolio turnover increases the Fund’s trading costs (which are not reflected in annual Fund operating expenses or in the example) and may have an adverse impact on the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund is intended to provide investment income from securities paying interest at rates that increase or decrease in response to changes in market interest rates. The Fund’s overall strategy is therefore to invest in a portfolio of adjustable-rate securities, including adjustable-rate, mortgage-backed securities (ARMs) and floating-rate, collateralized mortgage obligations (CMOs) issued or guaranteed by U.S. government agencies and government sponsored enterprises (GSEs). The Fund may also invest in ARMs and floating-rate CMOs that are not issued or guaranteed by a GSE but that are rated by a nationally recognized statistical rating organization (NRSRO) in one of its two highest categories. Under normal circumstances, the Fund may also invest up to 20% of its assets in fixed-rate, mortgage-backed securities and other fixed-rate securities. The Fund’s investment strategy will depend primarily on the types of ARMs and CMOs available in the market.

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

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Interest Rate Risks. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer durations. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.

·   Prepayment Risks. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities.

·   Credit Risks. Credit risk is the possibility that a security will default by failing to pay interest or principal when due. If this occurs, the Fund will lose money.

·   Liquidity Risks. The non-government, mortgage-backed securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.

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

PERFORMANCE: BAR CHART AND TABLE

Risk/Return Bar Chart

The bar chart and performance table below reflect historical performance data for the Fund’s Institutional Shares. The performance information shown below will help you analyze the Fund’s investment risks in light of its historical returns. The bar chart shows the variability of the Fund’s Institutional Shares total returns on a calendar year-by-year basis. 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 1-800-341-7400.

The Fund’s Institutional Shares total return for the nine-month period from January 1, 2010 to September 30, 2010, was 2.09%.

Within the periods shown in the bar chart, the Fund’s Institutional Shares highest quarterly return was 2.21% (quarter ended December 31, 2000). Its lowest quarterly return was (0.42)% (quarter ended June 30, 2004).

Average Annual Total Return Table

In addition to Return Before Taxes, Return After Taxes is shown for the Fund’s Institutional Shares to illustrate the effect of federal taxes on Fund returns. Actual after-tax returns depend on each investor’s personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through tax-deferred programs, such as IRA or 401(k) plans.

(FOR THE PERIOD ENDED DECEMBER 31, 2009)

	1 Year	5 Years	10 Years
Institutional Shares:
Return Before Taxes	4.17%	4.10%	3.92%
Return After Taxes on Distributions	3.44%	2.79%	2.56%
Return After Taxes on Distributions and Sale of Fund Shares	2.70%	2.73%	2.52%
Bank of America Merrill Lynch 1-Year U.S. Treasury Note Index1 (reflects no deduction for fees, expenses or taxes)	0.80%	3.62%	3.80%

1 The Bank of America Merrill Lynch 1-Year U.S. Treasury Note Index is an unmanaged index tracking one-year U.S. government securities.

FUND MANAGEMENT

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

Todd A. Abraham, Senior Portfolio Manager, has been the Fund's portfolio manager since August 1995.

PURCHASE AND SALE OF FUND SHARES

The minimum initial investment amount for the Fund’s Institutional Shares is generally $1,000,000.and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

TAX INFORMATION

The Fund’s distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

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

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus. The Fund is intended to provide investment income from securities paying interest at rates that increase or decrease in response to changes in market interest rates. The Fund also intends to qualify as a permissible investment for federal credit unions and savings associations, and as an appropriate direct investment for national banks, and will limit its investments accordingly. The Fund’s overall strategy is therefore to invest in a portfolio of adjustable rate securities. As a fundamental investment policy, the Fund invests at least 65% of the value of its total assets in a professionally managed portfolio of U.S. government securities consisting primarily of adjustable and floating rate mortgage securities which are issued or guaranteed by the U.S. government, its agencies or instrumentalities. Any change to this policy would require the approval of the Fund’s shareholders. The balance of the portfolio may be invested in securities that are not issued or guaranteed by a U.S. government agency or GSE, but that have been rated by a nationally recognized statistical rating organization (NRSRO) in one of its two highest rating categories. A description of the various types of securities in which the Fund invests, other investment techniques used by the Fund, and their risks, immediately follows this strategy section.

Normally, adjustable rate mortgage-backed securities (ARMs) and floating rate collateralized mortgage obligations (CMOs) will constitute most of the Fund’s portfolio. The Fund’s investment strategy will depend primarily on the types of ARMs and CMOs available in the market. The Fund will select securities based on the relative yield of available adjustable rate securities with comparable risks and other characteristics. Significant characteristics of adjustable rate securities include the frequency of interest rate adjustments and any limitations on the amount of adjustments. Although the Fund will invest primarily in ARMs and floating rate CMOs issued or guaranteed by GSEs, it may also invest in non-government ARMs, floating rate CMOs and other adjustable rate securities that offer higher incremental yields as compensation for their increased credit risks.

Under normal circumstances, the Fund may also invest up to 20 percent of its assets in fixed-rate, mortgage-backed securities and other securities paying interest at fixed rates. The Fund uses these securities to increase the income provided by the portfolio. The amount and type of fixed-rate securities held in the Fund’s portfolio will depend on, among other factors, the relative yields of fixed and adjustable rate securities.

Decisions to purchase or sell particular securities are based on a fundamental analysis of their sensitivity to changes in interest rates, interest rate volatility, the yield curve and inflation, among other factors. The Adviser uses this fundamental analysis to compare the potential income and return from available securities with comparable durations, risks and other characteristics. However, there is no assurance that a security will perform as expected or that the fundamental analysis will incorporate all relevant information.

The Fund invests in overnight repurchase agreements in order to maintain sufficient cash to pay for daily net redemptions and portfolio transactions.

Because the Fund refers to adjustable rate investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to invest, under normal circumstances, less than 80 percent of its assets in adjustable rate securities. For purposes of this limitation, an adjustable rate security includes any fixed-income security that requires periodic changes in its interest rate based upon changes in a recognized index interest rate or another method of determining prevailing interest rates.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in shorter-term debt securities and similar obligations or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such investments could affect the Fund’s investment returns and/or the ability to achieve the Fund’s investment objectives.

What are the Principal Securities in Which the Fund Invests?

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

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the principal amount of the security must be paid, normally within a specified time.

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 principal types of fixed-income securities in which the Fund invests:

Treasury Securities (A Fixed-Income Security)

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

Government Securities (A Fixed-Income Security)

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

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

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

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

Mortgage-Backed Securities (A Fixed-Income Security)

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

Mortgage-backed securities come in a variety of forms. The simplest forms of mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other mortgage-backed securities may have more complicated financial structures.

ARMs

ARMs are pass-through certificates representing interests in an underlying pool of mortgages with adjustable interest rates. The frequency and amount of the interest rate adjustments depends on the terms of the underlying mortgages. ARMs typically provide for an initial fixed-rate, followed by an initial adjustment to a rate based on a recognized index. Thereafter, the interest rate is adjusted on a periodic basis to track changes in the index. Most ARMs limit the amount of any individual interest rate adjustment and may also limit the cumulative amount of the adjustments. For example, an ARM may provide for an initial rate of interest fixed for one, three or five years, followed by an initial adjustment that cannot exceed a limit that may range from two to five percent, with subsequent semi-annual or annual adjustments that cannot exceed two percent. The ARM may further limit the cumulative amount of all adjustments to not more than five percent over the initial fixed rate.

Adjustments in the interest rate paid on ARMs tend to reduce their price volatility, particularly as compared to fixed-rate, mortgage-backed securities. However, for some ARMs, the initial fixed-interest rate may continue for a number of years. Generally, the longer the initial rate period the more sensitive the ARM’s price will be to changes in interest rates. Less frequent adjustments, and tighter limitations on the amount of adjustments, will also increase the price volatility of an ARM.

Collateralized Mortgage Obligations (A Type of Mortgage-Backed Security)

CMOs, including interests in real estate mortgage investment conduits (REMICs), allocate payments and prepayments from an underlying pass-through certificate among holders of different classes of mortgage-backed securities. This creates different prepayment and interest rate risks for each CMO class. The degree of risk depends upon the structure of the CMOs.

Floaters and Inverse Floaters (Types of CMOs)

Another variant allocates interest payments between two classes of CMOs. One class (“Floaters”) receives a share of interest payments based upon a market index such as the London Interbank Offered Rate (LIBOR). The other class (“Inverse Floaters”) receives any remaining interest payments from the underlying mortgages. Floater classes receive more interest (and Inverse Floater classes receive correspondingly less interest) as interest rates rise. This shifts prepayment and interest rate risks from the Floater to the Inverse Floater class, reducing the price volatility of the Floater class and increasing the price volatility of the Inverse Floater class.

Asset-Backed Securities (A Fixed-Income Security)

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

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Repurchase Agreements

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

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

Repurchase agreements are subject to credit risks.

Investment Ratings for Investment-Grade Securities

The Adviser will determine whether a security is investment grade based upon the credit ratings given by one or more NRSROs. For example, Standard & Poor’s, an NRSRO, assigns ratings to investment-grade securities (AAA, AA, A and BBB) based on their assessment of the likelihood of the issuer’s inability to pay interest or principal (“default”) when due on each security. Lower credit ratings correspond to higher credit risk. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment that the security is comparable to investment grade. If a security is downgraded below the minimum quality grade discussed above, the Adviser will reevaluate the security, but will not be required to sell it.

What are the Specific Risks of Investing in the Fund?

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

INTEREST RATE RISKS

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

Interest rate changes have a greater effect on the price of fixed-income securities with longer durations. Duration measures the price sensitivity of a fixed-income security to changes in interest rates. Although the adjustable-rate securities held by the Fund will tend to have lower durations than fixed-rate securities with the same maturity, this difference will be reduced by the extent of the initial fixed-rate period, and by limitations on the amount and frequency of the interest rate adjustments.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due) payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a Fund holding mortgage-backed securities.

For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities.

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

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

Credit Risks

Credit risk is the possibility that a security will default by failing to pay interest or principal when due. If this occurs, the Fund will lose money.

Many fixed-income securities receive credit ratings from services such as Standard & Poor’s and Moody’s Investor Services, Inc. These services assign ratings to securities by assessing the likelihood of default. Lower credit ratings correspond to higher credit risk. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment.

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

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

LIQUIDITY RISKS

Trading opportunities are more limited for ARMs and CMOs that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities may also lead to an increase in their price volatility.

Liquidity risk also refers to the possibility that the Fund may not be able to sell a security when it wants to. If this happens, the Fund will be required to continue to hold the security, and the Fund could incur losses.

REGULATORY COMPLIANCE

The Fund will not purchase a residual interest in CMO or REMIC. In addition, the Fund will not purchase zero coupon securities with maturities greater than 10 years.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next calculated net asset value of a Share (NAV). A Share’s NAV is determined as of the end of regular trading on the New York Stock Exchange (NYSE) (normally 4:00 p.m. Eastern time), each day the NYSE is open. The Fund calculates the NAV of each class by valuing the assets allocated to the Share’s class, subtracting the liabilities allocated to the class and dividing the balance by the number of Shares of the class outstanding. The Fund’s current NAV and public offering price may be found at FederatedInvestors.com and in the mutual funds section of certain newspapers under “Federated.”

You can purchase, redeem or exchange Shares any day the NYSE is open.

When the Fund holds fixed-income securities that trade on days the NYSE is closed, the value of the Fund’s assets may change on days you cannot purchase or redeem Shares.

In calculating its NAV, the Fund generally values investments as follows:

·   Fixed-income securities acquired with remaining maturities greater than 60 days are fair valued using price evaluations provided by a pricing service approved by the Board of Trustees (“Board”).

·   Fixed-income securities acquired with remaining maturities of 60 days or less are valued at their cost (adjusted for the accretion of any discount or amortization of any premium).

If the Fund cannot obtain a price or price evaluation from a pricing service for an investment, the Fund may attempt to value the investment based upon the mean of bid and asked quotations, or fair value the investment based on price evaluations, from one or more dealers. If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, the Fund uses the fair value of the investment determined in accordance with the procedures described below. There can be no assurance that the Fund could purchase or sell an investment at the price used to calculate the Fund’s NAV.

Shares of other mutual funds are valued based upon their reported NAVs. The prospectuses for these mutual funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

FAIR VALUATION AND SIGNIFICANT EVENTS PROCEDURES

The Board has ultimate responsibility for determining the fair value of investments for which market quotations are not readily available. The Board has appointed a Valuation Committee comprised of officers of the Fund and of the Adviser to assist in this responsibility and in overseeing the calculation of the NAV. The Board has also authorized the use of pricing services recommended by the Valuation Committee to provide fair value evaluations of the current value of certain investments for purposes of calculating the NAV. In the event that market quotations and price evaluations are not available for an investment, the Valuation Committee determines the fair value of the investment in accordance with procedures adopted by the Board. The Board periodically reviews and approves the fair valuations made by the Valuation Committee and any changes made to the procedures. The Fund’s SAI discusses the methods used by pricing services and the Valuation Committee to value investments.

Using fair value to price investments may result in a value that is different from an investment’s most recent closing price and from the prices used by other mutual funds to calculate their NAVs. The Valuation Committee generally will not change an investment’s fair value in the absence of new information relating to the investment or its issuer such as changes in the issuer’s business or financial results, or relating to external market factors, such as trends in the market values of comparable securities. This may result in less frequent, and larger, changes in fair values as compared to prices based on market quotations or price evaluations from pricing services or dealers.

The Board also has adopted procedures requiring an investment to be priced at its fair value whenever the Adviser determines that a significant event affecting the value of the investment has occurred between the time as of which the price of the investment would otherwise be determined and the time as of which the NAV is computed. An event is considered significant if there is both an affirmative expectation that the investment’s value will change in response to the event and a reasonable basis for quantifying the resulting change in value. Examples of significant events that may occur after the close of the principal market on which a security is traded, or after the time of a price evaluation provided by a pricing service or a dealer, include:

·   With respect to price evaluations of fixed-income securities determined before the close of regular trading on the NYSE, actions by the Federal Reserve Open Market Committee and other significant trends in U.S. fixed-income markets;

·   Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded; and

·   Announcements concerning matters such as acquisitions, recapitalizations or litigation developments or a natural disaster affecting the issuer’s operations or regulatory changes or market developments affecting the issuer’s industry.

The Valuation Committee uses a pricing service to determine the fair value of equity securities traded principally in foreign markets when the Adviser determines that there has been a significant trend in the U.S. equity markets or in index futures trading. For other significant events, the Fund may seek to obtain more current quotations or price evaluations from alternative pricing sources. If a reliable alternative pricing source is not available, the Valuation Committee will determine the fair value of the investment using another method approved by the Board. The Board has ultimate responsibility for any fair valuations made in response to a significant event.

The fair valuation of securities following a significant event can serve to reduce arbitrage opportunities for short-term traders to profit at the expense of long-term investors in the Fund. For example, such arbitrage opportunities may exist when the market on which portfolio securities are traded closes before the Fund calculates its NAV, which is typically the case with Asian and European markets. However, there is no assurance that these significant event procedures will prevent dilution of the NAV by short-term traders. See “Account and Share Information–Frequent Trading Policies” for other procedures the Fund employs to deter such short-term trading.

In connection with a request to purchase Shares, you should provide documentation sufficient to verify your status as an Eligible Investor. As a general matter, Shares are not available for direct investment by natural persons.

The following categories of Eligible Investors are not subject to any minimum initial investment amount for the purchase of Shares (however, such accounts remain subject to the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus):

·   An investor participating in a wrap program or other fee-based program spon­sored by a financial intermediary;

·   An investor participating in a no-load network or platform sponsored by a financial intermediary where Federated has entered into an agreement with the intermediary;

·   A trustee/director, employee or former employee of the Fund, the Adviser, the Distributor and their affiliates; an immediate family member of these individuals, or a trust, pension or profit-sharing plan for these individuals;

·   An employer-sponsored retirement plan;

·   A trust institution investing on behalf of its trust customers;

·   Additional sales to an investor (including a natural person) who owned Institutional Shares of the Fund as of December 31, 2008;

·   An investor (including a natural person) who acquired Institutional Shares of a Federated fund pursuant to the terms of an agreement and plan of reorganiza­tion which permits the investor to acquire such shares; and

·   In connection with an acquisition of an investment management or advisory business, or related investment services, products or assets, by Federated or its investment advisory subsidiaries, an investor (including a natural person) who: (1) becomes a client of an investment advisory subsidiary of Federated; or (2) is a shareholder or interest holder of a pooled investment vehicle or product that becomes advised or subadvised by a Federated investment advisory subsidiary as a result of such an acquisition other than as a result of a fund reorganization transaction pursuant to an agreement and plan of reorganization.

The following categories of Eligible Investors are subject to applicable minimum initial investment amounts for the purchase of Shares (see “How to Purchase Shares” below):

·   An investor, other than a natural person, purchasing Shares directly from the Fund; and

·   In connection with an initial purchase of Shares through an exchange, an investor (including a natural person) who owned Institutional Shares of another Federated fund as of December 31, 2008.

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

Payments to Financial Intermediaries

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

SERVICE FEES

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

ACCOUNT ADMINISTRATION FEES

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

RECORDKEEPING FEES

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

NETWORKING FEES

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

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

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

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

How to Purchase Shares

Eligible Investors may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund in the manner described above under “How is the Fund Sold?” The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

Where applicable, the required minimum initial investment for Institutional Shares is generally $1,000,000. There is no required minimum subsequent investment amount. All accounts, including those for which there is no minimum initial investment amount required, are subject to the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus.

Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Establish an account with the financial intermediary; and submit your purchase order to the financial intermediary before the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time). You will receive the next calculated NAV if the financial intermediary forwards the order on the same day, and forwards your payment by the prescribed trade settlement date (typically within one to three business days) to the Fund’s transfer agent, State Street Bank and Trust Company (“Transfer Agent”). You will become the owner of Shares and receive dividends when your payment is received in accordance with these time frames (provided that, if payment is received in the form of a check, the check clears). If your payment is not received in accordance with these time frames, or a check does not clear, your purchase will be canceled and you could be liable for any losses, fees or expenses incurred by the Fund or the Fund’s Transfer Agent.

Financial intermediaries should send payments according to the instructions in the sections “By Wire” or “By Check.”

DIRECTLY FROM THE FUND

·   Establish your account with the Fund  by submitting a completed New Account Form; and

·   Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares and your Shares will be priced at the next calculated NAV after the Fund receives your wire or your check.  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.

An institution may establish an account and place an order by calling the Fund, and the Shares will be priced at the next calculated NAV after the Fund receives the order.

Payment should be made in U.S. dollars and drawn on a U.S. bank. 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.

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable), and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

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

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

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

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

Shares of the Fund may be redeemed for cash or exchanged for shares of the same class of other Federated funds on days on which the Fund computes its NAV. Redemption requests may be made by telephone or in writing.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary by the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time). The redemption amount you will receive is based upon the next calculated NAV after the Fund receives the order from your financial intermediary.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by simply calling the Fund at 1-800-341-7400.

If you call before the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time), you will receive a redemption amount based on that day’s NAV.

By Mail

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

You will receive a redemption amount based on the next calculated NAV after the Fund receives your written request in proper form.

Send requests by mail to:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds

30 Dan Road

Canton, MA 02021

All requests must include:

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

·   amount to be redeemed or exchanged;

·   signatures of all shareholders exactly as registered; and

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

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

Signature Guarantees

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

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

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

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

·   transferring into another fund with a different shareholder registration.

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

PAYMENT METHODS FOR REDEMPTIONS

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

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

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

Redemption In-Kind

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

LIMITATIONS ON REDEMPTION PROCEEDS

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

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

·   during periods of market volatility;

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

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

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

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

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

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

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

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

EXCHANGE PRIVILEGE

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

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

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

An exchange is treated as a redemption and a subsequent purchase, and is a taxable transaction. The Fund may modify or terminate the exchange privilege at any time. In addition, the Fund may terminate your exchange privilege if your exchange activity is found to be excessive under the Fund’s frequent trading policies.  See “Account and Share Information–Frequent Trading Policies.”

ADDITIONAL CONDITIONS

Telephone Transactions

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

Share Certificates

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

Account and Share Information

CONFIRMATIONS AND ACCOUNT STATEMENTS

You will receive confirmation of purchases, redemptions and exchanges . In addition, you will receive periodic statements reporting all account activity, including  dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders. If you purchase Shares by wire, you begin earning dividends on the day your wire is received. If you purchase Shares by check, you begin earning dividends on the business day after the Fund receives your check. In either case, you earn dividends through the day your redemption request is received.

In addition, 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.

If you purchase Shares just before the record date for a capital gain distribution, you will pay the full price for the Shares and then receive a portion of the price back in the form of a taxable distribution, whether or not you reinvest the distribution in Shares. Therefore, you should consider the tax implications of purchasing Shares shortly before the record date for a capital gain. Contact your financial intermediary or the Fund for information concerning when dividends and capital gains will be paid.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund’s distributions, if applicable, is available in the “Products” section of Federated’s website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders–Source of Distributions” link under “Related Information.”

ACCOUNTS WITH LOW BALANCES

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

TAX INFORMATION

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

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

FREQUENT TRADING POLICIES

Frequent or short-term trading into and out of the Fund can have adverse consequences for the Fund and shareholders who use the Fund as a long-term investment vehicle.  Such trading in significant amounts can disrupt the Fund’s investment strategies (e.g., by requiring it to sell investments at inopportune times or maintain excessive short-term or cash positions to support redemptions), increase brokerage and administrative costs and affect the timing and amount of taxable gains distributed by the Fund.  Investors engaged in such trading may also seek to profit by anticipating changes in the Fund’s NAV in advance of the time as of which NAV is calculated.

The Fund’s Board has approved policies and procedures intended to discourage excessive frequent or short-term trading of the Fund’s Shares. The Fund monitors trading in Fund Shares in an effort to identify disruptive trading activity. The Fund monitors trades into and out of the Fund within a period of 30 days or less. The Fund may also monitor trades into and out of the Fund for potentially disruptive trading activity over periods longer than 30 days.  The size of Share transactions subject to monitoring varies. Where it is determined that a shareholder has exceeded the detection amounts twice within a period of 12 months, the Fund will temporarily preclude the shareholder from making further purchases or exchanges of Fund Shares.  If the shareholder continues to exceed the detection amounts for specified periods, the Fund will impose lengthier trading restrictions on the shareholder, up to and including permanently precluding the shareholder from making any further purchases or exchanges of Fund Shares.  Whether or not the specific monitoring limits are exceeded, the Fund’s management or the Adviser may determine from the amount, frequency or pattern of purchases and redemptions or exchanges that a shareholder is engaged in excessive trading that is or could be detrimental to the Fund and other shareholders and may preclude the shareholder from making further purchases or exchanges of Fund Shares. No matter how the Fund defines its limits on frequent trading of Fund Shares, other purchases and sales of Fund Shares may have adverse effects on the management of the Fund’s portfolio and its performance.

The Fund’s frequent trading restrictions do not apply to purchases and sales of Fund Shares by other Federated funds. These funds impose the same frequent trading restrictions as the Fund at their shareholder level. In addition, allocation changes of the investing Federated fund are monitored, and the managers of the recipient fund must determine that there is no disruption to their management activity. The intent of this exception is to allow investing fund managers to accommodate cash flows that result from non-abusive trading in the investing fund, without being stopped from such trading because the aggregate of such trades exceeds the monitoring limits. Nonetheless, as with any trading in Fund Shares, purchases and redemptions of Fund Shares by other Federated funds could adversely affect the management of the Fund’s portfolio and its performance.

The Fund’s objective is that its restrictions on short-term trading should apply to all shareholders that are subject to the restrictions, regardless of the number or type of accounts in which Shares are held.  However, the Fund anticipates that limitations on its ability to identify trading activity to specific shareholders, including where Shares are held through intermediaries in multiple or omnibus accounts, will mean that these restrictions may not be able to be applied uniformly in all cases.

Who Manages the Fund?

The Board governs the Fund. The Board selects and oversees the Adviser, Federated Investment Management Company. The Adviser manages the Fund’s assets, including buying and selling portfolio securities.

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

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

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

PORTFOLIO MANAGEMENT INFORMATION

Todd A. Abraham

Todd A. Abraham has been the Fund’s Portfolio Manager since August 1995. He is Vice President of the Fund. Mr. Abraham has been a Portfolio Manager since 1995 and a Vice President of the Fund’s Adviser since 1997. Mr. Abraham joined Federated in 1993 as an Investment Analyst and served as Assistant Vice President from 1995 to 1997. Mr. Abraham served as a Portfolio Analyst at Ryland Mortgage Co. from 1992 to 1993. Mr. Abraham has received the Chartered Financial Analyst designation and an M.B.A. in Finance from Loyola College.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, management of other accounts and ownership of securities in the Fund.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.60% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

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

Legal Proceedings

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

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

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

Financial Information

FINANCIAL HIGHLIGHTS

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

This information for the fiscal year ended August 31, 2010, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund’s audited financial statements, is included in the Annual Report. As described in the Annual Report, the information for the prior years was audited by Ernst & Young LLP, another independent registered public accounting firm, which issued an unqualified opinion.

On May 14, 2010, the Fund’s Board, upon recommendation of the Audit Committee, appointed KPMG LLP as the Fund’s independent registered public accounting firm for the fiscal year ending August 31, 2010. On the same date, the Fund’s former auditor, Ernst & Young LLP, resigned.  See the Fund’s Annual Report for further information regarding the change in independent registered public accounting firm.

Appendix A: Hypothetical Investment and Expense Information

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

PROSPECTUS

October 31, 2010

INSTITUTIONAL SERVICE SHARES (TICKER FASSX)

A mutual fund seeking to provide current income consistent with minimal volatility of principal by investing primarily in adjustable- and floating-rate 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.

Fund Summary Information

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

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

RISK/RETURN SUMMARY: FEES AND EXPENSES

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

Shareholder Fees
Fees Paid Directly From Your Investment
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, as applicable)	None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends (and other Distributions) (as a percentage of offering price)	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None
Exchange Fee	None
Annual Fund Operating Expenses
Expenses That You Pay Each Year as a Percentage of the Value of Your Investment
Management Fee	0.60%
Distribution (12b-1) Fee	0.05%
Other Expenses	0.40%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	1.06%
Fee Waivers and/or Expense Reimbursements1	0.16%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.90%

1 The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses (excluding Acquired Fund Fees and Expenses) paid by the Fund’s Institutional Service Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.89% (the “Fee Limit”) through the later of (the “Termination Date”): (a) October 31, 2011; or (b) the date of the Fund’s next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the agreement of the Fund’s Board of Trustees.

Example

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

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

1 Year	$108
3 Years	$337
5 Years	$585
10 Years	$1,294

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). Dollar-roll transactions and prepayments of mortgage-backed securities will cause the Fund to have an increased portfolio turnover rate which is likely to generate shorter-term gains (losses) for its shareholders. Portfolio turnover increases the Fund’s trading costs (which are not reflected in annual Fund operating expenses or in the example) and may have an adverse impact on the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS AND PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund is intended to provide investment income from securities paying inter­est at rates that increase or decrease in response to changes in market interest rates. The Fund’s overall strategy is therefore to invest in a portfolio of adjustable-rate securities, including adjustable-rate, mortgage-backed securities (ARMs) and floating-rate, collateralized mortgage obligations (CMOs) issued or guaranteed by U.S. government agencies and government-sponsored enterprises (GSEs). The fund may also invest in ARMs and floating rate CMOs that are not issued or guaran­teed by a GSE but that are rated by a nationally recognized statistical rating organization (NRSRO) in one of its two highest categories. Under normal circumstances, the Fund may also invest up to 20% of its assets in fixed-rate, mortgage-backed securities and other fixed-rate securities. The Fund’s investment strategy will depend primarily on the types of ARMs and CMOs available in the market.

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

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

·   Interest Rate Risks. Prices of fixed-income securities generally fall when interest rates rise. Interest rate changes have a greater effect on the price of fixed-income securities with longer durations. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.

·   Prepayment Risks. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities.

·   Credit Risks. Credit risk is the possibility that a security will default by failing to pay interest or principal when due. If this occurs, the Fund will lose money.

·   Liquidity Risks. The non-government, mortgage-backed securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.

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

PERFORMANCE: BAR CHART AND TABLE

Risk/Return Bar Chart

The bar chart and performance table below reflect historical performance data for the Fund’s Institutional Service Shares.  The performance information shown below will help you analyze the Fund’s investment risks in light of its historical returns. The bar chart shows the variabil­ity of the Fund’s Institutional Service Shares 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 1-800-341-7400.

The Fund’s Institutional Service Shares total return for the nine-month period from January 1, 2010 to September 30, 2010, was 1.90%.

Within the periods shown in the bar chart, the Fund’s Institutional Service Shares highest quarterly return was 2.15% (quarter ended December 31, 2000). Its lowest quarterly return was (0.48)% (quarter ended June 30, 2004).

Average Annual Total Return Table

In addition to Return Before Taxes, Return After Taxes is shown for the Fund’s Institutional Service Shares to illustrate the effect of federal taxes on Fund returns. Actual after-tax returns depend on each investor’s personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through tax-deferred programs, such as IRA or 401(k) plans.

 (FOR THE PERIOD ENDED DECEMBER 31, 2009)

	1 Year	5 Years	10 Years
Institutional Service Shares:
Return Before Taxes	3.91%	3.86%	3.68%

FUND MANAGEMENT

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

Todd A. Abraham, Senior Portfolio Manager, has been the Fund's portfolio manager since August 1995.

PURCHASE AND SALE OF FUND SHARES

The minimum initial investment amount for the Fund’s Institutional Service Shares is generally $1,000,000 and there is no required minimum subsequent investment amount.

You may purchase, redeem or exchange Shares of the Fund on any day the New York Stock Exchange (NYSE) is open. Shares may be purchased through a financial intermediary or directly from the Fund, by wire or by check. Redeem or exchange through a financial intermediary or directly from the Fund by telephone at 1-800-341-7400 or by mail.

TAX INFORMATION

The Fund’s distributions are taxable as ordinary income or capital gains except when your investment is through an Individual Retirement Account (IRA).

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

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

What are the Fund’s Investment Strategies?

While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies in this Prospectus. The Fund is intended to provide investment income from securities paying interest at rates that increase or decrease in response to changes in market interest rates. The Fund also intends to qualify as a permissible investment for federal credit unions and savings associations, and as an appropriate direct investment for national banks, and will limit its investments accordingly. The Fund’s overall strategy is therefore to invest in a portfolio of adjustable rate securities. As a fundamental investment policy, the Fund invests at least 65% of the value of its total assets in a professionally managed portfolio of U.S. government securities consisting primarily of adjustable and floating rate mortgage securities which are issued or guaranteed by the U.S. government, its agencies or instrumentalities. Any change to this policy would require the approval of the Fund’s shareholders. The balance of the portfolio may be invested in securities that are not issued or guaranteed by a U.S. government agency or GSE, but that have been rated by a nationally recognized statistical rating organization (NRSRO) in one of its two highest rating categories. A description of the various types of securities in which the Fund invests, other investment techniques used by the Fund, and their risks, immediately follows this strategy section.

Normally, adjustable rate mortgage-backed securities (ARMs) and floating rate collateralized mortgage obligations (CMOs) will constitute most of the Fund’s portfolio. The Fund’s investment strategy will depend primarily on the types of ARMs and CMOs available in the market. The Fund will select securities based on the relative yield of available adjustable rate securities with comparable risks and other characteristics. Significant characteristics of adjustable rate securities include the frequency of interest rate adjustments and any limitations on the amount of adjustments. Although the Fund will invest primarily in ARMs and floating rate CMOs issued or guaranteed by GSEs, it may also invest in non-government ARMs, floating rate CMOs and other adjustable rate securities that offer higher incremental yields as compensation for their increased credit risks.

Under normal circumstances, the Fund may also invest up to 20 percent of its assets in fixed-rate, mortgage-backed securities and other securities paying interest at fixed rates. The Fund uses these securities to increase the income provided by the portfolio. The amount and type of fixed-rate securities held in the Fund’s portfolio will depend on, among other factors, the relative yields of fixed and adjustable rate securities.

Decisions to purchase or sell particular securities are based on a fundamental analysis of their sensitivity to changes in interest rates, interest rate volatility, the yield curve and inflation, among other factors. The Adviser uses this fundamental analysis to compare the potential income and return from available securities with comparable durations, risks and other characteristics. However, there is no assurance that a security will perform as expected or that the fundamental analysis will incorporate all relevant information.

The Fund invests in overnight repurchase agreements in order to maintain sufficient cash to pay for daily net redemptions and portfolio transactions.

Because the Fund refers to adjustable rate investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to invest, under normal circumstances, less than 80 percent of its assets in adjustable rate securities. For purposes of this limitation, an adjustable rate security includes any fixed-income security that requires periodic changes in its interest rate based upon changes in a recognized index interest rate or another method of determining prevailing interest rates.

TEMPORARY INVESTMENTS

The Fund may temporarily depart from its principal investment strategies by investing its assets in shorter-term debt securities and similar obligations or holding cash. It may do this in response to unusual circumstances, such as: adverse market, economic or other conditions (for example, to help avoid potential losses, or during periods when there is a shortage of appropriate securities); to maintain liquidity to meet shareholder redemptions; or to accommodate cash inflows. It is possible that such investments could affect the Fund’s investment returns and/or the ability to achieve the Fund’s investment objectives.

What are the Principal Securities in Which the Fund Invests?

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

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the principal amount of the security must be paid, normally within a specified time.

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 principal types of fixed-income securities in which the Fund invests:

Treasury Securities (A Fixed-Income Security)

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

Government Securities (A Fixed-Income Security)

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

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

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

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

Mortgage-Backed Securities (A Fixed-Income Security)

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

Mortgage-backed securities come in a variety of forms. The simplest forms of mortgage-backed securities are pass-through certificates. Holders of pass-through certificates receive a pro rata share of all net interest and principal payments and prepayments from the underlying mortgages. As a result, the holders assume all interest rate and prepayment risks of the underlying mortgages. Other mortgage-backed securities may have more complicated financial structures.

ARMs

ARMs are pass-through certificates representing interests in an underlying pool of mortgages with adjustable interest rates. The frequency and amount of the interest rate adjustments depends on the terms of the underlying mortgages. ARMs typically provide for an initial fixed-rate, followed by an initial adjustment to a rate based on a recognized index. Thereafter, the interest rate is adjusted on a periodic basis to track changes in the index. Most ARMs limit the amount of any individual interest rate adjustment and may also limit the cumulative amount of the adjustments. For example, an ARM may provide for an initial rate of interest fixed for one, three or five years, followed by an initial adjustment that cannot exceed a limit that may range from two to five percent, with subsequent semi-annual or annual adjustments that cannot exceed two percent. The ARM may further limit the cumulative amount of all adjustments to not more than five percent over the initial fixed rate.

Adjustments in the interest rate paid on ARMs tend to reduce their price volatility, particularly as compared to fixed-rate, mortgage-backed securities. However, for some ARMs, the initial fixed-interest rate may continue for a number of years. Generally, the longer the initial rate period the more sensitive the ARM’s price will be to changes in interest rates. Less frequent adjustments, and tighter limitations on the amount of adjustments, will also increase the price volatility of an ARM.

Collateralized Mortgage Obligations (A Type of Mortgage-Backed Security)

CMOs, including interests in real estate mortgage investment conduits (REMICs), allocate payments and prepayments from an underlying pass-through certificate among holders of different classes of mortgage-backed securities. This creates different prepayment and interest rate risks for each CMO class. The degree of risk depends upon the structure of the CMOs.

Floaters and Inverse Floaters (Types of CMOs)

Another variant allocates interest payments between two classes of CMOs. One class (“Floaters”) receives a share of interest payments based upon a market index such as the London Interbank Offered Rate (LIBOR). The other class (“Inverse Floaters”) receives any remaining interest payments from the underlying mortgages. Floater classes receive more interest (and Inverse Floater classes receive correspondingly less interest) as interest rates rise. This shifts prepayment and interest rate risks from the Floater to the Inverse Floater class, reducing the price volatility of the Floater class and increasing the price volatility of the Inverse Floater class.

Asset-Backed Securities (A Fixed-Income Security)

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

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Repurchase Agreements

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

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

Repurchase agreements are subject to credit risks.

Investment Ratings for Investment-Grade Securities

The Adviser will determine whether a security is investment grade based upon the credit ratings given by one or more NRSROs. For example, Standard & Poor’s, an NRSRO, assigns ratings to investment-grade securities (AAA, AA, A and BBB) based on their assessment of the likelihood of the issuer’s inability to pay interest or principal (“default”) when due on each security. Lower credit ratings correspond to higher credit risk. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment that the security is comparable to investment grade. If a security is downgraded below the minimum quality grade discussed above, the Adviser will reevaluate the security, but will not be required to sell it.

What are the Specific Risks of Investing in the Fund?

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

INTEREST RATE RISKS

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

Interest rate changes have a greater effect on the price of fixed-income securities with longer durations. Duration measures the price sensitivity of a fixed-income security to changes in interest rates. Although the adjustable-rate securities held by the Fund will tend to have lower durations than fixed-rate securities with the same maturity, this difference will be reduced by the extent of the initial fixed-rate period, and by limitations on the amount and frequency of the interest rate adjustments.

PREPAYMENT RISKS

Unlike traditional fixed-income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due) payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payment of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a Fund holding mortgage-backed securities.

For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate, and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities.

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

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

Credit Risks

Credit risk is the possibility that a security will default by failing to pay interest or principal when due. If this occurs, the Fund will lose money.

Many fixed-income securities receive credit ratings from services such as Standard & Poor’s and Moody’s Investor Services, Inc. These services assign ratings to securities by assessing the likelihood of default. Lower credit ratings correspond to higher credit risk. If a security has not received a rating, the Fund must rely entirely upon the Adviser’s credit assessment.

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

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

LIQUIDITY RISKS

Trading opportunities are more limited for ARMs and CMOs that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities may also lead to an increase in their price volatility.

Liquidity risk also refers to the possibility that the Fund may not be able to sell a security when it wants to. If this happens, the Fund will be required to continue to hold the security, and the Fund could incur losses.

REGULATORY COMPLIANCE

The Fund will not purchase a residual interest in CMO or REMIC. In addition, the Fund will not purchase zero coupon securities with maturities greater than 10 years.

What Do Shares Cost?

CALCULATION OF NET ASSET VALUE

When the Fund receives your transaction request in proper form (as described in this Prospectus), it is processed at the next calculated net asset value of a Share (NAV). A Share’s NAV is determined as of the end of regular trading on the New York Stock Exchange (NYSE) (normally 4:00 p.m. Eastern time), each day the NYSE is open. The Fund calculates the NAV of each class by valuing the assets allocated to the Share’s class, subtracting the liabilities allocated to the class and dividing the balance by the number of Shares of the class outstanding. The Fund’s current NAV and public offering price may be found at FederatedInvestors.com and in the mutual funds section of certain newspapers under “Federated.”

You can purchase, redeem or exchange Shares any day the NYSE is open.

When the Fund holds fixed-income securities that trade on days the NYSE is closed, the value of the Fund’s assets may change on days you cannot purchase or redeem Shares.

In calculating its NAV, the Fund generally values investments as follows:

·   Fixed-income securities acquired with remaining maturities greater than 60 days are fair valued using price evaluations provided by a pricing service approved by the Board of Trustees (“Board”).

·   Fixed-income securities acquired with remaining maturities of 60 days or less are valued at their cost (adjusted for the accretion of any discount or amortization of any premium).

If the Fund cannot obtain a price or price evaluation from a pricing service for an investment, the Fund may attempt to value the investment based upon the mean of bid and asked quotations, or fair value the investment based on price evaluations, from one or more dealers. If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, the Fund uses the fair value of the investment determined in accordance with the procedures described below. There can be no assurance that the Fund could purchase or sell an investment at the price used to calculate the Fund’s NAV.

Shares of other mutual funds are valued based upon their reported NAVs. The prospectuses for these mutual funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

FAIR VALUATION AND SIGNIFICANT EVENTS PROCEDURES

The Board has ultimate responsibility for determining the fair value of investments for which market quotations are not readily available. The Board has appointed a Valuation Committee comprised of officers of the Fund and of the Adviser to assist in this responsibility and in overseeing the calculation of the NAV. The Board has also authorized the use of pricing services recommended by the Valuation Committee to provide fair value evaluations of the current value of certain investments for purposes of calculating the NAV. In the event that market quotations and price evaluations are not available for an investment, the Valuation Committee determines the fair value of the investment in accordance with procedures adopted by the Board. The Board periodically reviews and approves the fair valuations made by the Valuation Committee and any changes made to the procedures. The Fund’s SAI discusses the methods used by pricing services and the Valuation Committee to value investments.

Using fair value to price investments may result in a value that is different from an investment’s most recent closing price and from the prices used by other mutual funds to calculate their NAVs. The Valuation Committee generally will not change an investment’s fair value in the absence of new information relating to the investment or its issuer such as changes in the issuer’s business or financial results, or relating to external market factors, such as trends in the market values of comparable securities. This may result in less frequent, and larger, changes in fair values as compared to prices based on market quotations or price evaluations from pricing services or dealers.

The Board also has adopted procedures requiring an investment to be priced at its fair value whenever the Adviser determines that a significant event affecting the value of the investment has occurred between the time as of which the price of the investment would otherwise be determined and the time as of which the NAV is computed. An event is considered significant if there is both an affirmative expectation that the investment’s value will change in response to the event and a reasonable basis for quantifying the resulting change in value. Examples of significant events that may occur after the close of the principal market on which a security is traded, or after the time of a price evaluation provided by a pricing service or a dealer, include:

·   With respect to price evaluations of fixed-income securities determined before the close of regular trading on the NYSE, actions by the Federal Reserve Open Market Committee and other significant trends in U.S. fixed-income markets;

·   Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded; and

·   Announcements concerning matters such as acquisitions, recapitalizations or litigation developments or a natural disaster affecting the issuer’s operations or regulatory changes or market developments affecting the issuer’s industry.

The Valuation Committee uses a pricing service to determine the fair value of equity securities traded principally in foreign markets when the Adviser determines that there has been a significant trend in the U.S. equity markets or in index futures trading. For other significant events, the Fund may seek to obtain more current quotations or price evaluations from alternative pricing sources. If a reliable alternative pricing source is not available, the Valuation Committee will determine the fair value of the investment using another method approved by the Board. The Board has ultimate responsibility for any fair valuations made in response to a significant event.

The fair valuation of securities following a significant event can serve to reduce arbitrage opportunities for short-term traders to profit at the expense of long-term investors in the Fund. For example, such arbitrage opportunities may exist when the market on which portfolio securities are traded closes before the Fund calculates its NAV, which is typically the case with Asian and European markets. However, there is no assurance that these significant event procedures will prevent dilution of the NAV by short-term traders. See “Account and Share Information–Frequent Trading Policies” for other procedures the Fund employs to deter such short-term trading.

How is the Fund Sold?

The Fund offers two Share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This Prospectus relates only to Institutional Service Shares. All Share classes have different  expenses which affect their performance.  Contact your financial intermediary or call 1-800-341-7400 for more information concerning the other class.

The Fund’s Distributor, Federated Securities Corp., markets the Shares described in this Prospectus to Eligible Investors, as described below. In connection with a request to purchase Shares, you should provide documentation sufficient to verify your status as an Eligible Investor. As a general matter, Shares are not available for direct investment by natural persons.

The following categories of Eligible Investors are not subject to any minimum initial investment amount for the purchase of Shares (however, such accounts remain subject to the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus):

·   An investor participating in a wrap program or other fee-based program sponsored by a financial intermediary;

·   An investor participating in a no-load network or platform sponsored by a financial intermediary where Federated has entered into an agreement with the intermediary;

·   A trustee/director, employee or former employee of the Fund, the Adviser, the Distributor and their affiliates; an immediate family member of these individuals, or a trust, pension or profit-sharing plan for these individuals;

·   An employer-sponsored retirement plan;

·   A trust institution investing on behalf of its trust customers;

·   Additional sales to an investor (including a natural person) who owned Institutional Service Shares of the Fund as of December 31, 2008;

·   An investor (including a natural person) who acquired Institutional Service Shares of a Federated fund pursuant to the terms of an agreement and plan of reorganization which permits the investor to acquire such shares; and

·   In connection with an acquisition of an investment management or advisory business, or related investment services, products or assets, by Federated or its investment advisory subsidiaries, an investor (including a natural person) who: (1) becomes a client of an investment advisory subsidiary of Federated; or (2) is a shareholder or interest holder of a pooled investment vehicle or product that becomes advised or subadvised by a Federated investment advisory subsidiary as a result of such an acquisition other than as a result of a fund reorganization transaction pursuant to an agreement and plan of reorganization.

The following categories of Eligible Investors are subject to applicable minimum initial investment amounts for the purchase of Shares (see “How to Purchase Shares” below):

·   An investor, other than a natural person, purchasing Shares directly from the Fund; and

·   In connection with an initial purchase of Shares through an exchange, an investor (including a natural person) who owned Institutional Service Shares of another Federated fund as of December 31, 2008.

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

Payments to Financial Intermediaries

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

RULE 12B-1 FEES

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees of up to  0.05% of average net assets to the Distributor for the sale, distribution, administration and customer servicing of the Fund’s Institutional Service Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different  marketing fees.

SERVICE FEES

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

ACCOUNT ADMINISTRATION FEES

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

RECORDKEEPING FEES

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

NETWORKING FEES

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

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

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

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

How to Purchase Shares

Eligible Investors may purchase Shares through a financial intermediary, directly from the Fund or through an exchange from another Federated fund in the manner described above under “How is the Fund Sold?” The Fund reserves the right to reject any request to purchase or exchange Shares. New investors must submit a completed New Account Form.

Where applicable, the required minimum initial investment for Institutional Service Shares is generally $1,000,000. There is no required minimum subsequent investment amount. All accounts, including those for which there is no minimum initial investment amount required, are subject to the Fund’s policy on “Accounts with Low Balances” as discussed later in this Prospectus.

Financial intermediaries may impose higher or lower minimum investment requirements on their customers than those imposed by the Fund. Keep in mind that financial intermediaries may charge you fees for their services in connection with your Share transactions.

THROUGH A FINANCIAL INTERMEDIARY

Establish an account with the financial intermediary; and submit your purchase order to the financial intermediary before the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time). You will receive the next calculated NAV if the financial intermediary forwards the order on the same day, and forwards your payment by the prescribed trade settlement date (typically within one to three business days) to the Fund’s transfer agent, State Street Bank and Trust Company (“Transfer Agent”). You will become the owner of Shares and receive dividends when your payment is received in accordance with these time frames (provided that, if payment is received in the form of a check, the check clears). If your payment is not received in accordance with these time frames, or a check does not clear, your purchase will be canceled and you could be liable for any losses, fees or expenses incurred by the Fund or the Fund’s Transfer Agent.

Financial intermediaries should send payments according to the instructions in the sections “By Wire” or “By Check.”

DIRECTLY FROM THE FUND

·   Establish your account with the Fund  by submitting a completed New Account Form; and

·   Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares and your Shares will be priced at the next calculated NAV after the Fund receives your wire or your check.  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.

An institution may establish an account and place an order by calling the Fund, and the Shares will be priced at the next calculated NAV after the Fund receives the order.

THROUGH AN EXCHANGE

You may purchase Shares through an exchange from any Federated fund or share class that does not have a stated sales charge or contingent deferred sales charge, except Federated Liberty U.S. Government Money Market Trust and Class K Shares. You must meet the minimum initial investment requirement for purchasing Shares (if applicable), and both accounts must have identical registrations.

BY AUTOMATED CLEARING HOUSE (ACH)

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

How to Redeem and Exchange Shares

You should redeem or exchange Shares:

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

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

Shares of the Fund may be redeemed for cash or exchanged for shares of the same class of other Federated funds on days on which the Fund computes its NAV. Redemption requests may be made by telephone or in writing.

THROUGH A FINANCIAL INTERMEDIARY

Submit your redemption or exchange request to your financial intermediary by the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time). The redemption amount you will receive is based upon the next calculated NAV after the Fund receives the order from your financial intermediary.

DIRECTLY FROM THE FUND

By Telephone

You may redeem or exchange Shares by simply calling the Fund at 1-800-341-7400.

If you call before the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time), you will receive a redemption amount based on that day’s NAV.

By Mail

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

You will receive a redemption amount based on the next calculated NAV after the Fund receives your written request in proper form.

Send requests by mail to:

The Federated Funds

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

The Federated Funds

30 Dan Road

All requests must include:

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

·   amount to be redeemed or exchanged;

·   signatures of all shareholders exactly as registered; and

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

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

Signature Guarantees

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

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

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

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

·   transferring into another fund with a different shareholder registration.

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

PAYMENT METHODS FOR REDEMPTIONS

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

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

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

Redemption In-Kind

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

LIMITATIONS ON REDEMPTION PROCEEDS

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

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

·   during periods of market volatility;

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

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

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

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

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

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

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

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

EXCHANGE PRIVILEGE

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

·   ensure that the account registrations are identical;

·   meet any applicable minimum initial investment requirements; and

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

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

The Fund may modify or terminate the exchange privilege at any time. In addition, the Fund may terminate your exchange privilege if your exchange activity is found to be excessive under the Fund’s frequent trading policies. See “Account and Share Information–Frequent Trading Policies.”

ADDITIONAL CONDITIONS

Telephone Transactions

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

Share Certificates

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

Account and Share Information

CONFIRMATIONS AND ACCOUNT STATEMENTS

You will receive confirmation of purchases, redemptions and exchanges.  In addition, you will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders. If you purchase Shares by wire, you begin earning dividends on the day your wire is received. If you purchase Shares by check, you begin earning dividends on the business day after the Fund receives your check. In either case, you earn dividends through the day your redemption request is received.

In addition, 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.

If you purchase Shares just before the record date for a capital gain distribution, you will pay the full price for the Shares and then receive a portion of the price back in the form of a taxable distribution, whether or not you reinvest the distribution in Shares. Therefore, you should consider the tax implications of purchasing Shares shortly before the record date for a capital gain. Contact your financial intermediary or the Fund for information concerning when dividends and capital gains will be paid.

Under the federal securities laws, the Fund is required to provide a notice to shareholders regarding the source of distributions made by the Fund if such distributions are from sources other than ordinary investment income. In addition, important information regarding the Fund’s distributions, if applicable, is available in the “Products” section of Federated’s website at FederatedInvestors.com. To access this information from the “Products” section of the website, click on the “Notice to Shareholders–Source of Distributions” link under “Related Information.”

ACCOUNTS WITH LOW BALANCES

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

TAX INFORMATION

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

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

FREQUENT TRADING POLICIES

Frequent or short-term trading into and out of the Fund can have adverse consequences for the Fund and shareholders who use the Fund as a long-term investment vehicle.  Such trading in significant amounts can disrupt the Fund’s investment strategies (e.g., by requiring it to sell investments at inopportune times or maintain excessive short-term or cash positions to support redemptions), increase brokerage and administrative costs and affect the timing and amount of taxable gains distributed by the Fund.  Investors engaged in such trading may also seek to profit by anticipating changes in the Fund’s NAV in advance of the time as of which NAV is calculated.

The Fund’s Board has approved policies and procedures intended to discourage excessive frequent or short-term trading of the Fund’s Shares. The Fund monitors trading in Fund Shares in an effort to identify disruptive trading activity. The Fund monitors trades into and out of the Fund within a period of 30 days or less. The Fund may also monitor trades into and out of the Fund for potentially disruptive trading activity over periods longer than 30 days.  The size of Share transactions subject to monitoring varies. Where it is determined that a shareholder has exceeded the detection amounts twice within a period of 12 months, the Fund will temporarily preclude the shareholder from making further purchases or exchanges of Fund Shares.  If the shareholder continues to exceed the detection amounts for specified periods, the Fund will impose lengthier trading restrictions on the shareholder, up to and including permanently precluding the shareholder from making any further purchases or exchanges of Fund Shares.  Whether or not the specific monitoring limits are exceeded, the Fund’s management or the Adviser may determine from the amount, frequency or pattern of purchases and redemptions or exchanges that a shareholder is engaged in excessive trading that is or could be detrimental to the Fund and other shareholders and may preclude the shareholder from making further purchases or exchanges of Fund Shares. No matter how the Fund defines its limits on frequent trading of Fund Shares, other purchases and sales of Fund Shares may have adverse effects on the management of the Fund’s portfolio and its performance.

The Fund’s frequent trading restrictions do not apply to purchases and sales of Fund Shares by other Federated funds. These funds impose the same frequent trading restrictions as the Fund at their shareholder level. In addition, allocation changes of the investing Federated fund are monitored, and the managers of the recipient fund must determine that there is no disruption to their management activity. The intent of this exception is to allow investing fund managers to accommodate cash flows that result from non-abusive trading in the investing fund, without being stopped from such trading because the aggregate of such trades exceeds the monitoring limits. Nonetheless, as with any trading in Fund Shares, purchases and redemptions of Fund Shares by other Federated funds could adversely affect the management of the Fund’s portfolio and its performance.

The Fund’s objective is that its restrictions on short-term trading should apply to all shareholders that are subject to the restrictions, regardless of the number or type of accounts in which Shares are held.  However, the Fund anticipates that limitations on its ability to identify trading activity to specific shareholders, including where Shares are held through intermediaries in multiple or omnibus accounts, will mean that these restrictions may not be able to be applied uniformly in all cases.

Who Manages the Fund?

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

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

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

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

PORTFOLIO MANAGEMENT INFORMATION

Todd A. Abraham

Todd A. Abraham has been the Fund’s Portfolio Manager since August 1995. He is Vice President of the Fund. Mr. Abraham has been a Portfolio Manager since 1995 and a Vice President of the Fund’s Adviser since 1997. Mr. Abraham joined Federated in 1993 as an Investment Analyst and served as Assistant Vice President from 1995 to 1997. Mr. Abraham served as a Portfolio Analyst at Ryland Mortgage Co. from 1992 to 1993. Mr. Abraham has received the Chartered Financial Analyst designation and an M.B.A. in Finance from Loyola College.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, management of other accounts and ownership of securities in the Fund.

ADVISORY FEES

The Fund’s investment advisory contract provides for payment to the Adviser of an annual investment advisory fee of 0.60% of the Fund’s average daily net assets. The Adviser may voluntarily waive a portion of its fee or reimburse the Fund for certain operating expenses.

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

Legal Proceedings

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

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

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

Financial Information

FINANCIAL HIGHLIGHTS

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

This information for the fiscal year ended August 31, 2010, has been audited by KPMG LLP, an independent registered public accounting firm, whose report, along with the Fund’s audited financial statements, is included in the Annual Report. As described in the Annual Report, the information for the prior years was audited by Ernst & Young LLP, another independent registered public accounting firm, which issued an unqualified opinion.

On May 14, 2010, the Fund’s Board, upon recommendation of the Audit Committee, appointed KPMG LLP as the Fund’s independent registered public accounting firm for the fiscal year ending August 31, 2010. On the same date, the Fund’s former auditor, Ernst & Young LLP, resigned.  See the Fund’s Annual Report for further information regarding the change in independent registered public accounting firm.

Appendix A: Hypothetical Investment and Expense Information

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

How is the Fund Organized?

The Fund is a diversified open-end, management investment company that was established under the laws of the Commonwealth of Massachusetts on May 21, 1985.

The Board of Trustees (“Board”) has established two classes of shares of the Fund, known as Institutional Shares and Institutional Service Shares (“Shares”). This SAI relates to both classes of Shares. The Fund’s investment adviser is Federated Investment Management Company (“Adviser”).

Securities In Which The Fund Invests

INVESTMENT OBJECTIVE

The Fund’s investment objective is to provide current income consistent with minimal volatility of principal. The investment objective may not be changed by the Fund’s Board without shareholder approval. 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 SAI.

INVESTMENT STRATEGIES

In shareholder reports and other description of the Fund’s investment strategy and performance, the Adviser may refer to general types of securities (such as U.S. Treasury or mortgage-backed securities) as “sectors” of the fixed-income market.

The Fund may also seek to increase its income by lending its portfolio securities or engaging in dollar roll transactions.

The Fund invests in overnight repurchase agreements in order to maintain sufficient cash to pay for daily net redemptions and portfolio transactions. In the event that the Fund does not have sufficient cash for these purposes, it could incur overdrafts, enter into reverse repurchase agreements or otherwise borrow money in accordance with its investment limitations. The Fund also reserves the right to redeem Shares in kind with portfolio securities. See PAYMENT METHOD FOR REDEMPTIONS–Redemptions In-Kind.

The Fund may also enter into repurchase agreements with longer terms (up to 12 months) if they offer higher returns than those expected from U.S. Treasury or agency securities having the same maturity.

Mortgage-backed, pass-through certificates are typically offered or traded on a to-be-announced or other delayed delivery basis. Other U.S. government securities may also be offered on a delayed delivery basis. The Fund will enter into trades on this basis in order to participate in these offerings or trade these securities.

Because the Fund refers to adjustable rate investments in its name, it will notify shareholders at least 60 days in advance of any change in its investment policies that would enable the Fund to invest, under normal circumstances, less than 80 percent of its assets in adjustable rate securities. For purposes of this limitation, an adjustable rate security includes any fixed-income security that requires periodic changes in its interest rate based upon changes in a recognized index interest rate or another method of determining prevailing interest rates.

The principal securities in which the Fund invests are described in the Fund’s Prospectus. In pursuing its investment strategy, the Fund also may invest in the following securities for any purpose that is consistent with its investment objective:

SECURITIES DESCRIPTIONS AND TECHNIQUES

FIXED-INCOME SECURITIES

Fixed-income securities pay interest, dividends or distributions at a specified rate.  The rate may be a fixed percentage of the principal or may be adjusted periodically.  In addition, the issuer of a fixed-income security must repay the principal amount of the security, normally within a specified time.

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

The following describes the types of fixed-income securities, in addition to those listed in the Prospectus, in which the Fund invests.

Sequential CMOs (A Type of CMO)

In a sequential pay CMO, one class of CMOs receives all principal payments and prepayments. The next class of CMOs receives all principal payments after the first class is paid off. This process repeats for each sequential class of CMO. As a result, each class of sequential pay CMOs reduces the prepayment risks of subsequent classes.

PACs, TACs and Companion Classes (A Type of CMO)

More sophisticated CMOs include planned amortization classes (PACs) and targeted amortization classes (TACs). PACs and TACs are issued with companion classes. PACs and TACs receive principal payments and prepayments at a specified rate. The companion classes receive principal payments and prepayments in excess of the specified rate. In addition, PACs will receive the companion classes’ share of principal payments, if necessary, to cover a shortfall in the prepayment rate. This helps PACs and TACs to control prepayment risks by increasing the risks to their companion classes.

OTHER INVESTMENTS, TRANSACTIONS, TECHNIQUES

Reverse Repurchase Agreements (A Fixed-Income Security)

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

Delayed Delivery Transactions

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

To Be Announced Securities (TBAs) (A Type of Delayed Delivery Transaction)

As with other delayed delivery transactions, a seller agrees to deliver a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms. For example, in a TBA mortgage-backed transaction, the Fund and the seller would agree upon the issuer, interest rate and terms of the underlying mortgages. The seller would not identify the specific underlying mortgages until it delivers the security. TBA mortgage-backed securities increase market risks because the underlying mortgages may be less favorable than anticipated by the Fund.

Dollar Rolls (A Type of Delayed Delivery Transaction)

Dollar rolls are transactions where the Fund sells mortgage-backed securities with a commitment to buy similar, but not identical, mortgage-backed securities on a future date at a lower price. Normally, one or both securities involved are TBA mortgage-backed securities. Dollar rolls are subject to interest risks and counterparty credit risks. These transactions may create leverage risks.

Investing in Securities of Other Investment Companies

The Fund may invest its assets in securities of other investment companies, including the securities of affiliated money market funds, as an efficient means of implementing its investment strategies and/or managing its uninvested cash. These other investment companies are managed independently of the Fund and incur additional fees and/or expenses which world, therefore, be borne indirectly by the Fund in connection with any such investment. However, the Adviser believes that the benefits and efficiencies of this approach should outweigh the potential additional fees and/or expenses.

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 counter-party credit risks.

Investment Ratings for Non-Government Mortgage-Backed Securities

The Adviser will determine whether a non-government mortgage-backed security is eligible for investment by the Fund based upon the credit ratings given by one or more NRSROs. For example, Standard & Poor’s (S&P), a rating service, assigns ratings to securities based on its assessment of the likelihood of the issuer’s inability to pay interest or principal (default) when due on each security. Lower credit ratings correspond to higher credit risk.

If a security is downgraded below the minimum quality grade discussed above, the Adviser will reevaluate the security, but will not be required to sell it.

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 Risks

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

RISKS ASSOCIATED WITH THE INVESTMENT ACTIVITIES OF OTHER ACCOUNTS

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

RISKS ASSOCIATED WITH TEMPORARY LIQUIDITY GUARANTEE PROGRAM

The Fund may invest in securities guaranteed by the Federal Deposit Insurance Corporation (“FDIC”), an instrumentality of the United States, under its Temporary Liquidity Guarantee Program (“Program”). Under the Program, if the issuer of the security does not make timely payment of principal or interest in accordance with the terms of such security, the FDIC will make scheduled payments of unpaid principal and interest.

In order to receive payments from the FDIC, the Fund would be required to make a written demand with a conforming proof of claim (collectively, “Demand”) following an issuer’s nonpayment of principal or interest. There is no designated period within which the FDIC is required to make guarantee payments after receipt and verification of the Demand. Accordingly, the guarantee payments on a portfolio security held by the Fund could be delayed from the date that payment was due under the terms of such security.

Investment Objective (and Policies) and Investment Limitations

FUNDAMENTAL INVESTMENT POLICY

The Fund’s investment objective is to provide current income consistent with minimal volatility of principal. The investment objective may not be changed by the Fund’s Trustees without shareholder approval.

As a fundamental investment policy, the Fund invests at least 65% of the value of its total assets in a professionally managed portfolio of U.S. government securities consisting primarily of adjustable and floating rate mortgage securities which are issued or guaranteed by the U.S. government, its agencies or instrumentalities.

This investment policy may not be changed by the Fund’s Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash, cash items, securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities, and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Borrowing Money and Issuing Senior Securities

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

Investing in Real Estate

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

Investing in Commodities

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

Underwriting

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

Lending

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

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

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

Illiquid Securities

The Fund will not purchase securities for which there is no readily available market, or enter into repurchase agreements or purchase time deposits that the fund cannot dispose of within seven days, if immediately after and as a result, the value of such securities would exceed, in the aggregate, 15% of the Fund’s net assets.

Investing in Other Investment Companies

The Fund may invest its assets in securities of other investment companies as an efficient means of carrying out its investment policies. It should be noted that investment companies incur certain expenses, such as management fees, and, therefore, any investment by the Fund in shares of other investment companies may be subject to such duplicate expenses. At the present time, the Fund expects that its investments in other investment companies may include shares of money market funds, including funds affiliated with the Fund’s investment Adviser.

Purchases on Margin

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

Pledging Assets

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

Securities Lending

The Fund may lend portfolio securities up to one-third of the value of its total assets to broker/dealers, banks, or other institutional borrowers of securities. The Fund will only enter into loan arrangements with broker/dealers, banks, or other institutions which the investment adviser has determined are creditworthy under guidelines established by the Fund’s Board. The Fund will receive collateral in the form of cash or U.S. government securities equal to at least 100% of the value of the securities loaned.

Stripped Mortgage Securities

The Fund will not invest in stripped mortgage securities, including securities which represent a share of only the interest payments or only the principal payments from underlying mortgage related securities.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be “cash items.” Except with respect to borrowing money, if a percentage limitations 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.

As a non-fundamental operating policy, for purposes of the foregoing policy, investments in transactions involving futures contracts and options, forward currency contracts, swap transaction and other financial contracts that settle by payment of cash are not deemed to be investments in commodities.

In applying the concentration restriction: (a) utility companies will be divided according to their services, for example, gas, gas transmission, electric and telephone will each be considered a separate industry; (b) financial service companies will be classified according to the end users of their services, for example, automobile finance, bank finance and diversified finance will each be considered a separate industry; and (c) asset-backed securities will be classified according to the underlying assets securing such securities. To conform to the current view of the SEC staff that only domestic bank instruments may be excluded from industry concentration limitations, as a matter of non-fundamental policy, the Fund will not exclude foreign bank instruments from industry concentration limitation tests so long as the policy of the SEC remains in effect. In addition, investments in bank instruments, and investments in certain industrial development bonds funded by activities in a single industry will be deemed to constitute investment in an industry, except when held for temporary defensive purposes. Foreign securities will not be excluded from industry concentration limits. The investment of more than 25% of the value of the fund’s total assets in any one industry will constitute “concentration.”

What Do Shares Cost?

DETERMINING MARKET VALUE OF SECURITIES

A Share’s NAV is determined as of the end of regular trading on the New York Stock Exchange (NYSE) (normally 4:00 p.m. Eastern time) each day the NYSE is open. The Fund calculates the NAV of each class by valuing the assets allocated to the Share’s class, subtracting the liabilities allocated to the class and dividing the balance by the number of Shares of the class outstanding. The NAV for each class of Shares may differ due to the variance in daily net income realized by each class. Such variance will reflect only accrued net income to which the Shareholders of a particular class are entitled.  The NAV is calculated to the nearest whole cent per Share.

In calculating its NAV, the Fund generally values investments as follows:

·   Equity securities listed on a U.S. securities exchange or traded through the U.S. national market system are valued at their last reported sale price or official closing price in their principal exchange or market. If a price is not readily available, such equity securities are valued based upon the mean of closing bid and asked quotations from one or more dealers.

·   Other equity securities traded primarily in the United States are valued based upon the mean of closing bid and asked quotations from one or more dealers.

·   Equity securities traded primarily through securities exchanges and regulated market systems outside the United States are valued at their last reported sale price or official closing price in their principal exchange or market. These prices may be adjusted for significant events occurring after the closing of such exchanges or market systems as described below. If a price is not readily available, such equity securities are valued based upon the mean of closing bid and asked quotations from one or more dealers.

·   Fixed-income securities and repurchase agreements acquired with remaining maturities of greater than 60 days are fair valued using price evaluations provided by a pricing service approved by the Board. The methods used by pricing services to determine such price evaluations are described below. If a price evaluation is not readily available, such fixed-income securities are fair valued based upon price evaluations from one or more dealers.

·   Fixed-income securities and repurchase agreements acquired with remaining maturities of 60 days or less are valued at their amortized cost as described below.

·   Futures contracts listed on exchanges are valued at their reported settlement price. Option contracts listed on exchanges are valued based upon the mean of closing bid and asked quotations reported by the exchange or from one or more futures commission merchants.

·   OTC derivative contracts are fair valued using price evaluations provided by various pricing services approved by the Board. The methods used by pricing services to determine such price evaluations are described below. If a price evaluation is not readily available, such derivative contracts are fair valued based upon price evaluations from one or more dealers or using a recognized pricing model for the contract.

·   Shares of other mutual funds are valued based upon their reported NAVs. The prospectuses for these mutual funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, the Fund uses the fair value of the investment determined in accordance with the procedures described below. There can be no assurance that the Fund could purchase or sell an investment at the price used to calculate the Fund’s NAV. The Fund will not use a pricing service or dealer who is an affiliated person of the Adviser to value investments.

Noninvestment assets and liabilities are valued in accordance with Generally Accepted Accounting Principles (GAAP). The NAV calculation includes expenses, dividend income, interest income and other income through the date of the calculation. Changes in holdings of investments and in the number of outstanding Shares are included in the calculation not later than the first business day following such change. Any assets or liabilities denominated in foreign currencies are converted into U.S. dollars using an exchange rate obtained from one or more currency dealers.

The Fund follows procedures that are common in the mutual fund industry regarding errors made in the calculation of its NAV. This means that, generally, the Fund will not correct errors of less than one cent per Share or errors that did not result in net dilution to the Fund.

Amortized Cost Values

Under the amortized cost valuation method, an investment is valued initially at its cost as determined in accordance with 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 the 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.

Fair Valuation and Significant Events Procedures

The Board has ultimate responsibility for determining the fair value of investments for which market quotations are not readily available. The Board has appointed a Valuation Committee comprised of officers of the Fund and of the Adviser to assist in this responsibility and in overseeing the calculation of the NAV. The Board has also authorized the use of pricing services recommended by the Valuation Committee to provide price evaluations of the current fair value of certain investments for purposes of calculating the NAV.

Pricing Service Valuations. Based on the recommendations of the Valuation Committee, the Board has authorized the Fund to use pricing services that provide daily fair value evaluations of the current value of certain investments, primarily fixed-income securities and OTC derivatives contracts. Different pricing services may provide different price evaluations for the same security because of differences in their methods of evaluating market values. Factors considered by pricing services in evaluating an investment include the yields or prices of investments of comparable quality, coupon, maturity, call rights and other potential prepayments, terms and type, reported transactions, indications as to values from dealers and general market conditions. A pricing service may find it more difficult to apply these and other factors to relatively illiquid or volatile investments, which may result in less frequent or more significant changes in the price evaluations of these investments. If a pricing service determines that it does not have sufficient information to use its standard methodology, it may evaluate an investment based on the present value of what investors can reasonably expect to receive from the issuer’s operations or liquidation.

Some pricing services provide a single price evaluation reflecting the bid-side of the market for an investment (a “bid” evaluation). Other pricing services offer both bid evaluations and price evaluations indicative of a price between the prices bid and asked for the investment (a “mid” evaluation). The Fund normally uses bid evaluations for U.S. Treasury and Agency securities, mortgage-backed securities and municipal securities. The Fund normally uses mid evaluations for other types of fixed-income securities and OTC derivative contracts.

Fair Valuation Procedures. The Board has established procedures for determining the fair value of investments for which price evaluations from pricing services or dealers and market quotations are not readily available. The procedures define an investment’s “fair value” as the price that the Fund might reasonably expect to receive upon its current sale. The procedures assume that any sale would be made to a willing buyer in the ordinary course of trading. The procedures require consideration of factors that vary based on the type of investment and the information available. Factors that may be considered in determining an investment’s fair value include: (1) the last reported price at which the investment was traded; (2) information provided by dealers or investment analysts regarding the investment or the issuer; (3) changes in financial conditions and business prospects disclosed in the issuer’s financial statements and other reports; (4) publicly announced transactions (such as tender offers and mergers) involving the issuer; (5) comparisons to other investments or to financial indices that are correlated to the investment; (6) with respect to fixed-income investments, changes in market yields and spreads; (7) with respect to investments that have been suspended from trading, the circumstances leading to the suspension; and (8) other factors that might affect the investment’s value.

The Valuation Committee is responsible for the day-to-day implementation of these procedures. The Valuation Committee may also authorize the use of a financial valuation model to determine the fair value of a specific type of investment. The Board periodically reviews and approves the fair valuations made by the Valuation Committee and any changes made to the procedures.

Using fair value to price investments may result in a value that is different from an investment’s most recent closing price and from the prices used by other mutual funds to calculate their NAVs. The fair value of an investment will generally remain unchanged in the absence of new information relating to the investment or its issuer, such as changes in the issuer’s business or financial results, or relating to external market factors, such as trends in the market values of comparable securities. This may result in less frequent, and larger, changes in fair value prices as compared to prices based on market quotations or price evaluations from pricing services or dealers.

Significant Events. The Board has adopted procedures requiring an investment to be priced at its fair value whenever the Adviser determines that a significant event affecting the value of the investment has occurred between the time as of which the price of the investment would otherwise be determined and the time as of which the NAV is computed. An event is considered significant if there is both an affirmative expectation that the investment’s value will change in response to the event and a reasonable basis for quantifying the resulting change in value. Examples of significant events that may occur after the close of the principal market on which a security is traded, or the time of a price evaluation provided by a pricing service or a dealer, include:

·   With respect to securities traded principally in foreign markets, significant trends in U.S. equity markets or in the trading of foreign securities index futures or options contracts;

·   With respect to price evaluations of fixed-income securities determined before the close of regular trading on the NYSE, actions by the Federal Reserve Open Market Committee and other significant trends in U.S. fixed-income markets;

·   Political or other developments affecting the economy or markets in which an issuer conducts its operations or its securities are traded; and

·   Announcements concerning matters such as acquisitions, recapitalizations or litigation developments, or a natural disaster affecting the issuer’s operations or regulatory changes or market developments affecting the issuer’s industry.

The Valuation Committee uses a pricing service to determine the fair value of equity securities traded principally in foreign markets when the Adviser determines that there has been a significant trend in the U.S. equity markets or in index futures trading. The pricing service uses models that correlate changes between the closing and opening price of equity securities traded primarily in non-U.S. markets to changes in prices in U.S.-traded securities and derivative contracts. The pricing service seeks to employ the model that provides the most significant correlation based on a periodic review of the results. The model uses the correlation to adjust the reported closing price of a foreign equity security based on information available up to the close of the NYSE.

For other significant events, the Fund may seek to obtain more current quotations or price evaluations from alternative pricing sources. If a reliable alternative pricing source is not available, the fair value of the investment is determined using the methods discussed above in “Fair Valuation Procedures.” The Board has ultimate responsibility for any fair valuations made in response to a significant event.

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 (INSTITUTIONAL SERVICE 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.

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

ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES

The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries. In some cases, such payments may be made by, or funded from the resources of, companies affiliated with the Distributor (including the Adviser). While Financial Industry Regulatory Authority (FINRA) regulations limit the sales charges that you may bear, there are no limits with regard to the amounts that the Distributor may pay out of its own resources. In addition to the payments which are generally described herein and in the Prospectus, the financial intermediary also may receive payments under the Rule 12b-1 Plan and/or Service Fees. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Funds 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. An in-kind purchase may be treated as a sale of your securities for federal tax purposes; please consult your tax adviser regarding potential tax liability.

Subaccounting Services

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

Redemption In-Kind

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

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

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

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

Massachusetts Partnership Law

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

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

FEDERAL INCOME TAX

The annual incentive amount is determined based primarily on Investment Product Performance (IPP) and, to a lesser extent, Financial Success, and may be paid entirely in cash, or in a combination of cash and restricted stock of Federated Investors, Inc. (“Federated”). The total combined annual incentive opportunity is intended to be competitive in the market for this portfolio manager role.

IPP is measured on a rolling one, three and five calendar year pre-tax gross total return basis vs. the Fund's benchmark (i.e., Bank of America Merrill Lynch 1-Year U.S. Treasury Index), and vs. the Fund's designated peer group of comparable accounts. Performance periods are adjusted if a portfolio manager has been managing an account for less than five years; accounts with less than one year of performance history under a portfolio manager may be excluded. As noted above, Mr. Abraham is also the portfolio manager for other accounts in addition to the Fund. Such other accounts may have different benchmarks. The performance of certain of these accounts is excluded when calculating IPP. Within each performance measurement period, IPP is calculated with an equal weighting of each included account managed by the portfolio manager. In his role as co-head of the Government Bond team, Mr. Abraham has oversight responsibility for other portfolios that he does not personally manage. A portion of the IPP score is determined by the investment performance of these other portfolios vs. product specific benchmarks. In addition, Mr. Abraham serves on one or more Investment Teams that establish guidelines on various performance drivers (e.g., currency, duration, sector, volatility and/or yield curve) for taxable fixed income funds. A portion of the IPP score is based on Federated's senior management's assessment of team contributions. A portion of the bonus tied to the IPP score may be adjusted based on management's assessment of overall contributions to fund performance and any other factors as deemed relevant.

The Financial Success category is designed to tie the portfolio manager’s bonus, in part, to Federated’s overall financial results. Funding for the Financial Success category may be determined on a product or asset class basis, as well as on corporate financial results. Senior Management determines individual Financial Success bonuses on a discretionary basis, considering overall contributions and any other factors deemed relevant.

In addition, Todd Abraham was awarded a grant of restricted Federated stock. Awards of restricted stock are discretionary and are made in variable amounts based on the subjective judgment of Federated's senior management.

As a general matter, certain conflicts of interest may arise in connection with a portfolio manager’s management of a fund’s investments, on the one hand, and the investments of other accounts for which the portfolio manager is responsible, on the other. For example, it is possible that the various accounts managed could have different investment strategies that, at times, might conflict with one another to the possible detriment of the Fund. Alternatively, to the extent that the same investment opportunities might be desirable for more than one account, possible conflicts could arise in determining how to allocate them. Other potential conflicts might include conflicts created by specific portfolio manager compensation arrangements, and conflicts relating to selection of brokers or dealers to execute fund portfolio trades and/or specific uses of commissions from Fund portfolio trades (for example, research, or “soft dollars”). The Adviser has adopted policies and procedures and has structured the portfolio managers’ compensation in a manner reasonably designed to safeguard the Fund from being negatively affected as a result of any such potential conflicts.

Services Agreement

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

Other Related Services

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

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

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

VOTING PROXIES ON FUND PORTFOLIO SECURITIES

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

Proxy Voting Policies

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

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

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

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

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

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

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

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

Proxy Voting Procedures

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

Conflicts of Interest

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

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

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

Proxy Voting Report

A report on “Form N-PX” of how the Fund voted any proxies during the most recent 12-month period ended June 30 is available through Federated’s website. Go to FederatedInvestors.com; select “Products,” select the Fund; then use the link to “Prospectuses and Regulatory Reports” to access the link to Form N-PX. Form N-PX filings are also available at the SEC’s website at www.sec.gov.

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

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

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

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

BROKERAGE TRANSACTIONS AND INVESTMENT ALLOCATION

Equity securities may be traded in the over-the-counter market through broker/dealers acting as principal or agent, or in transactions directly with other investors. Transactions may also be executed on a securities exchange or through an electronic communications network. The Adviser seeks to obtain best execution of trades in equity securities by balancing the costs inherent in trading, including opportunity costs, market impact costs and commissions. As a general matter, the Adviser seeks to add value to its investment management by using market information to capitalize on market opportunities, actively seek liquidity and discover price. The Adviser continually monitors its trading results in an effort to improve execution. 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 fixed-income security. The Adviser’s receipt of research services (as described below) may also be a factor in the Adviser’s selection of brokers and dealers. The Adviser may also direct certain portfolio trades to a broker that, in turn, pays a portion of the Fund's operating expenses. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund’s Board.

ADMINISTRATOR

Federated Administrative Services (FAS), a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. FAS provides these at the following annual rates, based on the average aggregate daily net assets of the Fund and most of the other Federated funds:

Administrative Fee	Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%	on the first $5 billion
0.125 of 1%	on the next $5 billion
0.100 of 1%	on the next $10 billion
0.075 of 1%	on assets over $20 billion

The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. FAS may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

FAS also provides certain accounting and recordkeeping services with respect to the Fund’s portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

CUSTODIAN

State Street Bank and Trust Company, Boston, Massachusetts, is custodian for the securities and cash of the Fund.

How Does the Fund Measure Performance?

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

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

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

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year periods ended August 31, 2010.

Yield is given for the 30-day period ended August 31, 2010.

	30-Day Period	1 Year	5 Years	10 Years
Institutional Shares:
Total Return
Before Taxes	N/A	2.77%	4.22%	3.75%
After Taxes on Distributions	N/A	2.30%	2.99%	2.52%
After Taxes on Distributions and Sale of Shares	N/A	1.79%	2.88%	2.46%
Yield	1.10%	N/A	N/A	N/A
Institutional Service Shares:
Total Return
Before Taxes	N/A	2.51%	3.99%	3.50%
After Taxes on Distributions	N/A	2.13%	2.84%	2.36%
After Taxes on Distributions and Sale of Shares	N/A	1.63%	2.73%	2.31%
Yield	0.86%	N/A	N/A	N/A

TOTAL RETURN

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

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

Total returns after taxes are calculated in a similar manner, but reflect additional standard assumptions required by the SEC.

YIELD

The yield of Shares is calculated by dividing: (i) the net investment income per Share earned by the Shares over a 30-day period; by (ii) the maximum offering price per Share on the last day of the period. This number is then annualized using semi-annual compounding. This means that the amount of income generated during the 30-day period is assumed to be generated each month over a 12-month period and is reinvested every six months.  The yield does not necessarily reflect income actually earned by Shares because of certain adjustments required by the SEC and, therefore, may not correlate to the dividends or other distributions paid to shareholders.

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

Financial Information

The Financial Statements for the Fund for the fiscal year ended August 31, 2010, are incorporated herein by reference to the Annual Report to Shareholders of Federated Adjustable Rate Securities Fund dated August 31, 2010.

Investment Ratings

STANDARD & POOR’S (S&P) 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.

BB—Speculative. “BB” ratings indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time; however, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment-grade.

B—Highly speculative. “B” ratings indicate that significant credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

CCC, CC, C—High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments. A “CC” rating indicates that default of some kind appears probable. “C” ratings signal imminent default.

D—In payment default. The “D” rating category is used when payments on a financial commitment are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The “D” rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on a financial commitment are jeopardized.

MOODY’S INVESTORS SERVICE (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.

Baa—Bonds and preferred stock which are rated Baa are considered as medium-grade obligations (i.e., they are neither highly protected nor poorly secured). Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well.

Ba—Bonds and preferred stock which are rated Ba are judged to have speculative elements; their future cannot be considered as well-assured. Often the protection of interest and principal payments may be very moderate, and thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B—Bonds and preferred stock which are rated B generally lack characteristics of the desirable investment. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small.

Caa—Bonds and preferred stock which are rated Caa are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Ca—Bonds and preferred stock which are rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C—Bonds and preferred stock which are rated C are the lowest rated class of bonds and are typically in default, with little prospect for recovery of principal or interest.

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.

MOODY’S COMMERCIAL PAPER 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.

S&P COMMERCIAL PAPER RATINGS

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.

FITCH RATINGS COMMERCIAL PAPER RATING DEFINITIONS

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

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

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.

bb—Speculative. Assigned to issues where the issuer has, in A.M. Best’s opinion, speculative credit characteristics, generally due to a moderate margin of principal and interest payment protection and vulnerability to economic changes.

b—Very Speculative. Assigned to issues where the issuer has, in A.M. Best’s opinion, very speculative credit characteristics, generally due to a modest margin of principal and interest payment protection and extreme vulnerability to economic changes.

ccc, cc, c—Extremely Speculative. Assigned to issues where the issuer has, in A.M. Best’s opinion, extremely speculative credit characteristics, generally due to a minimal margin of principal and interest payment protection and/or limited ability to withstand adverse changes in economic or other conditions.

d—In Default. In default on payment of principal, interest or other terms and conditions. The rating also is utilized when a bankruptcy petition, or similar action, has been filed.

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.

AMB-4—Speculative. Assigned to issues where the issuer has, in A.M. Best’s opinion, speculative credit characteristics and is vulnerable to economic or other external changes, which could have a marked impact on the company’s ability to meet its commitments on short-term debt obligations.

d—In Default. In default on payment of principal, interest or other terms and conditions. The rating also is utilized when a bankruptcy petition, or similar action, has been filed.

A company’s Short-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.

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.
