Shareholder Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; to the extent applicable, distribution (12b-1) fees and/or shareholder services fees; and other Fund expenses. This Example is intended to help you to understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. It is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from September 1, 2006 to February 28, 2007.

ACTUAL EXPENSES

The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you incurred over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled "Expenses Paid During Period" to estimate the expenses attributable to your investment during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. Thus, you should not use the hypothetical account values and expenses to estimate the actual ending account balance or your expenses for the period. Rather, these figures are required to be provided to enable you to compare the ongoing costs of investing in the Fund with other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

	Beginning Account Value 9/1/2006	Ending Account Value 2/28/2007	Expenses Paid During Period¹
Actual:
Institutional Shares	$1,000	$1,023.60	$1.46
Institutional Service Shares	$1,000	$1,021.10	$3.96
Class Y Shares	$1,000	$1,023.50	$1.51
Hypothetical (assuming a 5% return before expenses):
Institutional Shares	$1,000	$1,023.36	$1.45
Institutional Service Shares	$1,000	$1,020.88	$3.96
Class Y Shares	$1,000	$1,023.31	$1.51

1 Expenses are equal to the Fund's annualized net expense ratios, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). The annualized net expense ratios are as follows:

Institutional Shares		0.29%
Institutional Service Shares		0.79%
Class Y Shares		0.30%

Management's Discussion of Fund Performance

MARKET OVERVIEW

The 12-month reporting period ended February 28, 2007 was a period of volatility for interest rates and the bond market. The three-year Treasury note yield increased from 4.67% on February 28, 2006, to a peak of 5.26% at the end of June, before falling as low as 4.42% in December and then back up to 4.93% in January. During February the yield reversed course again and closed at 4.57%, marginally lower than where it was 12 months earlier.

The reason for the volatility was shifting perceptions of the health of the economy and how that might impact future policy moves by the Federal Reserve Board (Fed). In the first half of 2006 Gross Domestic Product growth averaged 3.6%, powered by a strong increase in consumer spending. The core Personal Consumption Expenditures (PCE) deflator, the Fed's preferred measure of inflation, moved outside the Fed's presumed 1.0% - 2.0% comfort zone, increasing from 2.0% in January to 2.4% by August. In response to stronger growth and higher inflation, the Fed pushed up the federal funds rate to 5.25%. By the third quarter, however, a dramatic slowdown in housing, rising interest rates, and the lagged impact of higher energy prices began to be felt. Economic growth slowed, the core PCE deflator cooled to 2.2%, and the Fed stopped raising interest rates. In December and January, indications that housing was bottoming and a drop in energy prices reinvigorated the economy, and interest rates rose again in December and January. In February, fears that an imploding sub-prime mortgage lending market would infect other sectors of the economy sparked a flight to quality bid for short maturity Treasury bonds, and interest rates fell to close the reporting period slightly lower than where they started the period.

FUND PERFORMANCE

The fund's total return, based on net asset value, for the 12-month reporting period ended February 28, 2007 was 4.72% for Institutional Shares, 4.21% for Institutional Service Shares, and 4.72% for Class Y Shares. By comparison, the Merrill Lynch 1-3 Year Treasury Index (Index),¹ had a return of 4.76%. The Index is not adjusted to reflect sales charges, expenses, or other fees that the Securities and Exchange Commission (SEC) requires to be reflected in the fund's performance. Indexes are unmanaged, and it is not possible to invest directly in an index. The fund's total return for the most recently completed fiscal year reflected actual cash flows, transactions costs and other expenses which were not reflected in the total return of the Index.

Helping performance was a duration² that was lower than the Index during the first half of the year when rates were rising, and higher than the Index in the second half of the year when rates were falling.

Also benefiting performance was an allocation to federal agency securities. These government bonds are AAA rated³ but not always direct obligations of the federal government, and hence trade at slightly higher yields than Treasury securities. Agencies performed very well in 2006 as they outperformed Treasury securities.

One negative for performance was a position in a Treasury Inflation-Protected bond whose interest payment is calibrated to the consumer price index. This bond underperformed as falling energy prices in the second half of the year reduced the interest payments on the bond.

POSITIONING AND STRATEGY

As we start the new fiscal year, the fund's duration position is slightly shorter than the Index. Federated does not believe that a recession will occur in 2007, and therefore, believes that the recent flight to quality bid in the market has pushed interest rates below fair value. The fund has also reduced its allocation to agency securities as they appear rich relative to Treasury securities.

1 The Merrill Lynch 1-3 Year Treasury Index is an unmanaged index tracking short-term government securities with maturities between 1 and 2.99 years. The index is produced by Merrill Lynch, Pierce, Fenner & Smith, Inc. Investments cannot be made directly in an index.

2 Effective duration is a measure of a security's price sensitivity to changes in interest rates. The Adviser calculates effective duration using standard analytical models that quantify expected changes in portfolio value resulting from applicable yield curve changes. The Index may calculate its effective duration using different assumptions and models.

3 Bond prices are sensitive to changes in interest rates and a rise in interest rates can cause a decline in their prices. Credit ratings pertain only to the securities in the portfolio and do not protect fund shares against market risk.

Notes to Financial Statements

February 28, 2007

1. ORGANIZATION

Federated U.S. Government Securities Fund: 1-3 Years (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a diversified, open-end management investment company. The Fund offers three classes of shares: Institutional Shares, Institutional Service Shares, and Class Y Shares. All shares of the Fund have equal rights with respect to voting, except on class-specific matters. The primary investment objective of the Fund is to provide current income.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. These policies are in conformity with generally accepted accounting principles (GAAP) in the United States of America.

Investment Valuation

Market values of the Fund's portfolio securities are determined as follows:

futures contracts and options are generally valued at market values established by the exchanges on which they are traded at the close of trading on such exchanges. Options traded in the over-the-counter market are generally valued according to the mean between the last bid and the last asked price for the option as provided by an investment dealer or other financial institution that deals in the option. The Board of Trustees (the "Trustees") may determine in good faith that another method of valuing such investments is necessary to appraise their fair market value;
prices for total return swaps are based upon a valuation model incorporating underlying reference indexes, interest rates, yield curves and other market data or factors. Prices for credit default swaps are furnished by an independent pricing service and are based upon a valuation model incorporating default probabilities, recovery rates and other market data or factors;
for investments in other open-end regulated investment companies, based on net asset value;
for other fixed-income securities, according to prices as furnished by an independent pricing service, except that fixed-income securities with remaining maturities of less than 60 days at the time of purchase are valued at amortized cost; and
for all other securities at fair value as determined in accordance with procedures established by and under the general supervision of the Trustees.

Prices for fixed-income securities furnished by a pricing service may be based on a valuation matrix which incorporates both dealer-supplied valuations and electronic data processing techniques. Such prices are generally intended to be indicative of the bid prices currently offered to institutional investors for the securities. The Trustees have approved the use of such pricing services. A number of pricing services are available, and the Fund may use various pricing services or discontinue the use of any pricing service.

Prices provided by independent pricing services may be determined without relying exclusively on quoted prices and may consider institutional trading in similar groups of securities, yield, quality, stability, risk, coupon rate, maturity, type of issue, trading characteristics, and other market data or factors. From time to time, when prices cannot be obtained from an independent pricing service, securities may be valued based on quotes from broker-dealers or other financial institutions that trade the securities.

Repurchase Agreements

It is the policy of the Fund to require the other party to a repurchase agreement to transfer to the Fund's custodian or sub-custodian eligible securities or cash with a market value (after transaction costs) at least equal to the repurchase price to be paid under the repurchase agreement. The eligible securities are transferred to accounts with the custodian or sub-custodian in which the Fund holds a "securities entitlement" and exercises "control" as those terms are defined in the Uniform Commercial Code. The Fund has established procedures for monitoring the market value of the transferred securities and requiring the transfer of additional eligible securities if necessary to equal at least the repurchase price. These procedures also allow the other party to require securities to be transferred from the account to the extent that their market value exceeds the repurchase price or in exchange for other eligible securities of equivalent market value.

With respect to agreements to repurchase U.S. government securities and cash items, the Fund treats the repurchase agreement as an investment in the underlying securities and not as an obligation of the other party to the repurchase agreement. Other repurchase agreements are treated as obligations of the other party secured by the underlying securities. Nevertheless, the insolvency of the other party or other failure to repurchase the securities may delay the disposition of the underlying securities or cause the Fund to receive less than the full repurchase price. Under the terms of the repurchase agreement, any amounts received by the Fund in excess of the repurchase price and related transaction costs must be remitted to the other party.

The Fund may enter into repurchase agreements in which eligible securities are transferred into joint trading accounts maintained by the custodian or sub-custodian for investment companies and other clients advised by the Fund's adviser and its affiliates. The Fund will participate on a pro rata basis with the other investment companies and clients in its share of the securities transferred under such repurchase agreements and in its share of proceeds from any repurchase or other disposition of such securities.

Investment Income, Gains and Losses, Expenses and Distributions

Interest income and expenses are accrued daily. Distributions to shareholders are recorded on the ex-dividend date. Inflation adjustments to the face amount of inflation-indexed securities are included in interest income. Distributions of net investment income are declared daily and paid monthly. Investment income, realized and unrealized gains and losses, and certain fund-level expenses are allocated to each class based on relative average daily net assets, except that each class bears certain expenses unique to that class such as distribution and shareholder services fees. Dividends are declared separately for each class. No class has preferential dividend rights; differences in per share dividend rates are generally due to differences in separate class expenses.

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted for financial statement purposes.

Federal Taxes

It is the Fund's policy to comply with the Subchapter M provision of the Internal Revenue Code (the "Code") and to distribute to shareholders each year substantially all of its income. Accordingly, no provision for federal income tax is necessary.

When-Issued and Delayed Delivery Transactions

The Fund may engage in when-issued or delayed delivery transactions. The Fund records when-issued securities on the trade date and maintains security positions such that sufficient liquid assets will be available to make payment for the securities purchased. Securities purchased on a when-issued or delayed delivery basis are marked to market daily and begin earning interest on the settlement date. Losses may occur on these transactions due to changes in market conditions or the failure of counterparties to perform under the contract.

Securities Lending

The Fund participates in a securities lending program providing for the lending of government securities to qualified brokers. The Fund normally receives cash collateral for securities loaned that is invested in short-term securities including repurchase agreements. Collateral is maintained at a minimum level of 100% of the market value of investments loaned, plus interest, if applicable. Earnings on collateral are allocated between the securities lending agent, as a fee for its services under the program, and the Fund, according to agreed-upon rates.

As of February 28, 2007, securities subject to this type of arrangement and related collateral were as follows:

Market Value of Securities Loaned		Market Value of Collateral
$146,479,646		$151,022,000

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, expenses and revenues reported in the financial statements. Actual results could differ from those estimated.

Other

Investment transactions are accounted for on a trade date basis. Realized gains and losses from investment transactions are recorded on an identified cost basis.

4. FEDERAL TAX INFORMATION

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended February 28, 2007 and 2006, was as follows:

		2007		2006
Ordinary income		$17,130,927		$13,688,586

As of February 28, 2007, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	24,169
Net unrealized appreciation	$	782,027
Capital loss carryforward	$	(15,554,913	)

At February 28, 2007, the cost of investments for federal tax purposes was $473,282,105. The net unrealized appreciation of investments for federal tax purposes was $782,027. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $815,207 and net unrealized depreciation from investments for those securities having an excess of cost over value of $33,180.

At February 28, 2007, the Fund had a capital loss carryforward of $15,554,913 which will reduce the Fund's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Code and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income tax. Pursuant to the Code, such capital loss carryforward will expire as follows:

Expiration Year		Expiration Amount
2009		$1,790,620
2013		$2,379,272
2014		$6,748,189
2015		$4,636,832

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

Federated Investment Management Company, the Fund's investment adviser (the "Adviser"), receives for its services an annual investment adviser fee equal to 0.40% of the Fund's average daily net assets. For the year ended February 28, 2007, the Adviser voluntarily waived $1,018,240 of its fee.

Administrative Fee

Federated Administrative Services (FAS), under the Administrative Services Agreement, provides the Fund with administrative personnel and services. The fee paid to FAS is based on the average aggregate daily net assets of certain Federated funds as specified below:

Administrative Fee		Average Aggregate Daily Net Assets of the Federated Funds
0.150%		on the first $5 billion
0.125%		on the next $5 billion
0.100%		on the next $10 billion
0.075%		on assets in excess of $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. For the year ended February 28, 2007, the net fee paid to FAS was 0.076% of average aggregate daily net assets of the Fund.

Distribution Services Fee

The Fund has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1 under the Act. Under the terms of the Plan, the Fund will compensate Federated Securities Corp. (FSC), the principal distributor, from the daily net assets of the Fund's Institutional Service Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses of up to 0.25% of average daily net assets, annually, to compensate FSC. When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the year ended February 28, 2007, FSC retained $65,708 of fees paid by the Fund.

Shareholder Services Fee

The Fund may pay fees (Service Fees) up to 0.25% of the average daily net assets of the Fund's Institutional Shares and Institutional Service Shares to financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. For the year ended February 28, 2007, FSSC voluntarily waived $448 of its fee and voluntarily reimbursed $438 of shareholder services fees. The Fund's Class Y Shares Shares did not incur a shareholder services fee. For the year ended February 28, 2007, FSSC received $40,322 of fees paid by the Fund.

Commencing on August 1, 2005, and continuing through January 30, 2007, FSSC reimbursed daily a portion of the shareholder services fee. This reimbursement resulted from an administrative delay in the implementation of contractual terms of shareholder services fee agreements. This reimbursement amounted to $323,388 for the year ended February 28, 2007 and $204,580 for the year ended February 28, 2006.

Expense Limitation

The Adviser and its affiliates (which may include FSC, FAS and FSSC) have voluntarily agreed to waive their fees and/or reimburse expenses (including the distribution (12b-1) fee) so that the total operating expenses paid by the Fund's Institutional Shares, Institutional Service Shares and Class Y Shares (after the voluntary waivers and reimbursements) will not exceed 0.38%, 0.79% and 0.30%, respectively, for the fiscal year ending February 29, 2008. Although these actions are voluntary, the Adviser and its affiliates have agreed not to terminate these waivers and/or reimbursements until after April 30, 2008.

General

Certain of the Officers and Trustees of the Fund are Officers and Directors or Trustees of the above companies.

Transactions with Affiliated Companies

Affiliated holdings are mutual funds which are managed by the Adviser or an affiliate of the Adviser. The Adviser has agreed to reimburse the Fund for certain investment adviser fees as a result of transactions in other mutual funds. For the year ended February 28, 2007, the Adviser reimbursed $515 in connection with the investment in the affiliated mutual fund listed below. Transactions with affiliated companies during the year ended February 28, 2007 are as follows:

Affiliate		Balance of Shares Held 2/28/06		Purchases/ Additions		Sales/ Reductions		Balance of Shares Held 2/28/07		Value at 2/28/07		Dividend Income
Government Obligations Fund		0		30,237,992		15,364,810		14,873,182		$14,873,182		$28,613

6. LINE OF CREDIT

The Fund participates in a $150,000,000 unsecured, uncommitted revolving line of credit (LOC) agreement with PNC Bank. The LOC was made available for extraordinary or emergency purposes, primarily for financing redemption payments. Borrowings are charged interest at a rate of 0.65% over the federal funds rate. As of February 28, 2007, there were no outstanding loans. During the year ended February 28, 2007, the Fund did not utilize the LOC.

7. LEGAL PROCEEDINGS

Beginning in October 2003, Federated Investors, Inc. and various subsidiaries thereof (including the advisers and distributor for various investment companies, collectively, "Federated"), along with various investment companies sponsored by Federated ("Funds") were 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 Federated-sponsored mutual 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. These lawsuits began to be filed shortly after Federated's first public announcement that it had received requests for information on shareholder trading activities in the Funds from the Securities and Exchange Commission ("SEC"), the Office of the New York State Attorney General ("NYAG"), and other authorities. In that regard, on November 28, 2005, Federated announced that it had reached final settlements with the SEC and the NYAG with respect to those matters. As Federated previously reported in 2004, it has already paid approximately $8.0 million to certain funds as determined by an independent consultant. As part of these settlements, Federated agreed to pay for the benefit of fund shareholders additional disgorgement and a civil money penalty in the aggregate amount of an additional $72 million. Federated and various Funds have also been named as defendants in several additional lawsuits, the majority of which are now pending in the United States District Court for the Western District of Pennsylvania, alleging, among other things, excessive advisory and Rule 12b-1 fees. The Board of the Funds has retained the law firm of Dickstein Shapiro LLP to represent the Funds in these lawsuits. Federated and the Funds, and their respective counsel, are reviewing the allegations and intend to defend this litigation. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek unquantified 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, the ongoing adverse publicity and/or other developments resulting from the regulatory investigations will not result in increased Fund redemptions, reduced sales of Fund shares, or other adverse consequences for the Funds.

8. RECENT ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006. Recent SEC guidance allows implementing FIN 48 in fund NAV calculations as late as a fund's last NAV calculation in the first required financial statement reporting period. As a result, the Fund will adopt FIN 48 no later than August 31, 2007. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined.

In addition, in September 2006, FASB released Statement on Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157) which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of FAS 157 will have on the Fund's financial statement disclosures.

Report of Independent Registered Public Accounting Firm

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS:

We have audited the accompanying statement of assets and liabilities of Federated U.S. Government Securities Fund: 1-3 Years (the "Fund"), including the portfolio of investments, as of February 28, 2007, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of February 28, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Federated U.S. Government Securities Fund: 1-3 Years at February 28, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Evaluation and Approval of Advisory Contract

FEDERATED U.S. GOVERNMENT SECURITIES FUND: 1-3 YEARS (THE "FUND")

The Fund's Board reviewed the Fund's investment advisory contract at meetings held in May 2006. The Board's decision regarding the contract reflects the exercise of its business judgment on whether to continue the existing arrangements.

Prior to the meeting, the Adviser had recommended that the Federated Funds appoint a Senior Officer, whose duties include specified responsibilities relating to the process by which advisory fees are to be charged to a Federated Fund. The Senior Officer appointed by the Funds has the authority to retain consultants, experts, or staff as may be reasonably necessary to assist in the performance of his duties, reports directly to the Board, and may be terminated only with the approval of a majority of the independent members of the Board. The Senior Officer prepared and furnished to the Board an independent written evaluation that covered topics discussed below, which the Board considered, along with other information, in deciding to approve the advisory contract.

During its review of the contract, the Board considered compensation and benefits received by the Adviser. This included the fees received for services provided to the Fund by other entities in the Federated organization and research services received by the Adviser from brokers that execute Federated Fund trades, as well as advisory fees. The Board is also familiar with judicial decisions concerning allegedly excessive investment advisory fees which have indicated that the following factors may be relevant to an Adviser's fiduciary duty with respect to its receipt of compensation from a fund: the nature and quality of the services provided by the Adviser, including the performance of the Fund; the Adviser's cost of providing the services; the extent to which the Adviser may realize "economies of scale" as the Fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with the Fund; performance and expenses of comparable funds; and the extent to which the independent Board members are fully informed about all facts the Board deems relevant bearing on the Adviser's services and fees. The Board further considered management fees (including any components thereof) charged to institutional and other clients of the Adviser for like services and costs to the Adviser and its affiliates of supplying services pursuant to the management fee agreements, excluding any intra-corporate profit and profit margins of the Adviser and its affiliates from supplying such services. The Board was aware of these considerations and was guided by them in its review of the Fund's advisory contract to the extent they are appropriate and relevant, as discussed further below.

The Board considered and weighed these circumstances in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to the Federated Funds, and was assisted in its deliberations by the advice of independent legal counsel. Throughout the year, the Board has requested and received substantial and detailed information about the Fund and the Federated organization that was in addition to the extensive materials that comprise the Senior Officer's evaluation. Federated provided much of this information at each regular meeting of the Board, and furnished additional reports in connection with the particular meeting at which the Board's formal review of the advisory contract occurred. Between regularly scheduled meetings, the Board has received information on particular matters as the need arose. Thus, the Board's consideration of the advisory contract included review of the Senior Officer's evaluation, accompanying data and additional reports covering such matters as: the Adviser's investment philosophy, revenue, profitability, personnel and processes; investment and operating strategies; the Fund's short- and long-term performance (in absolute terms, both on a gross basis and net of expenses, as well as in relationship to its particular investment program and certain competitor or "peer group" funds and/or other benchmarks, as appropriate), and comments on the reasons for performance; the Fund's investment objectives; the Fund's expenses (including the advisory fee itself and the overall expense structure of the Fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); the use and allocation of brokerage commissions derived from trading the Fund's portfolio securities (if any); the nature, quality and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates; the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry and market practices; the range of comparable fees for similar funds in the mutual fund industry; the Fund's relationship to the Federated family of funds which include a comprehensive array of funds with different investment objectives, policies and strategies which are available for exchange without the incurrence of additional sales charges; compliance and audit reports concerning the Federated Funds and the Federated companies that service them (including communications from regulatory agencies), as well as Federated's responses to any issues raised therein; and relevant developments in the mutual fund industry and how the Federated Funds and/or Federated are responding to them. The Board's evaluation process is evolutionary. The criteria considered and the emphasis placed on relevant criteria change in recognition of changing circumstances in the mutual fund marketplace.

With respect to the Fund's performance and expenses in particular, the Board has found the use of comparisons to other mutual funds with comparable investment programs to be particularly useful, given the high degree of competition in the mutual fund business. The Board focused on comparisons with other similar mutual funds more heavily than non-mutual fund products or services because, simply put, they are more relevant. For example, other mutual funds are the products most like the Fund, they are readily available to Fund shareholders as alternative investment vehicles, and they are the type of investment vehicle in fact chosen and maintained by the Fund's investors. The range of their fees and expenses therefore appears to be a generally reliable indication of what consumers have found to be reasonable in the precise marketplace in which the Fund competes. The Fund's ability to deliver competitive performance when compared to its peer group was a useful indicator of how the Adviser is executing the Fund's investment program, which in turn assisted the Board in reaching a conclusion that the nature, extent, and quality of the Adviser's investment management services were such as to warrant continuation of the advisory contract. In this regard, the Senior Officer has reviewed Federated's fees for providing advisory services to products outside the Federated family of funds (e.g., institutional and separate accounts). He concluded that mutual funds and institutional accounts are inherently different products. Those differences included, but are not limited to targeting different investors, being subject to different laws and regulations, different legal structure, distribution costs, average account size and portfolio management techniques made necessary by different cash flows. The Senior Officer did not consider these fee schedules to be significant in determining the appropriateness of mutual fund advisory contracts.

The Senior Officer reviewed reports compiled by Federated, and directed the preparation of independent reports, regarding the performance of, and fees charged by, other mutual funds, noting his view that comparisons to fund peer groups is of significance in judging the reasonableness of proposed fees.

For the periods ending December 31, 2005, the Fund's performance for the one year period was above the median of the relevant peer group, and the Fund's performance fell below the median of the relevant peer group for the three year period. The Board discussed the Fund's performance with the Adviser and recognized the efforts being undertaken by the Adviser. The Board will continue to monitor these efforts and the performance of the Fund.

The Board also received financial information about Federated, including reports on the compensation and benefits Federated derived from its relationships with the Federated Funds. These reports covered not only the fees under the advisory contracts, but also fees received by Federated's subsidiaries for providing other services to the Federated Funds under separate contracts (e.g., for serving as the Federated Funds' administrator). The reports also discussed any indirect benefit Federated may derive from its receipt of research services from brokers who execute Federated Fund trades as well as waivers of fees and/or reimbursements of expenses. In order for a fund to be competitive in the marketplace, Federated and its affiliates frequently waived fees and/or reimbursed expenses and have indicated to the Board their intention to do so in the future, where appropriate.

Federated furnished reports, requested by the Senior Officer, that reported revenues on a fund by fund basis and made estimates of the allocation of expenses on a fund by fund basis, using allocation methodologies specified by the Senior Officer. The Senior Officer noted that, although they may apply consistent allocation processes, the inherent difficulties in allocating costs and the lack of consensus on how to allocate those costs causes such allocation reports to be of questionable value. The allocation reports were considered in the analysis by the Board but were determined to be of limited use.

The Board also reviewed profitability information for Federated and other publicly held fund management companies, provided by the Senior Officer, who noted the limited availability of such information, and concluded that Federated's profit margins did not appear to be excessive.

The Senior Officer's evaluation also discussed the notion of possible realization of "economies of scale" as a fund grows larger. The Board considered in this regard that the Adviser has made significant additional investments in the portfolio management and distribution efforts supporting all of the Federated Funds and that the benefits of any economies, should they exist, were likely to be enjoyed by the fund complex as a whole. Finally, the Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which is compounded by the lack of any common industry practice or general pattern with respect to structuring fund advisory fees with "breakpoints" that serve to reduce the fee as the fund attains a certain size. The Senior Officer did not recommend institution of breakpoints in pricing Federated's fund advisory services at this time.

During the year ending December 31, 2005, the Fund's investment advisory fee after waivers and expense reimbursements, if any, was below the median of the relevant peer group. The Board reviewed the fees and other expenses of the Fund with the Adviser and was satisfied that the overall expense structure of the Fund remained competitive. The Board will continue to monitor advisory fees and other expenses borne by the Fund.

No changes were recommended to, and no objection was raised to the continuation of the Fund's advisory contract, and the Senior Officer noted that Federated appeared to provide appropriate administrative services to the Fund for the fees paid. For 2005, the Board concluded that the nature, quality and scope of services provided the Fund by the Adviser and its affiliates were satisfactory.

In its decision to continue an existing investment advisory contract, the Board was mindful of the potential disruptions of the Fund's operations and various risks, uncertainties and other effects that could occur as a result of a decision to terminate or not renew an advisory contract. In particular, the Board recognized that most shareholders have invested in the Fund on the strength of the Adviser's industry standing and reputation and in the expectation that the Adviser will have a continuing role in providing advisory services to the Fund. Thus, the Board's approval of the advisory contract reflected the fact that it is the shareholders who have effectively selected the Adviser by virtue of having invested in the Fund.

The Board based its decision to approve the advisory contract on the totality of the circumstances and relevant factors and with a view to past and future long-term considerations. Not all of the factors and considerations identified above were relevant to every Federated Fund, nor did the Board consider any one of them to be determinative. With respect to the factors that were relevant, the Board's decision to approve the contract reflects its determination that Federated's performance and actions provided a satisfactory basis to support the decision to continue the existing arrangements.

The Senior Officer also made recommendations relating to the organization and availability of data and verification of processes for purposes of implementing future evaluations which the Adviser has agreed to implement.

(e)(1)      Audit Committee Policies regarding Pre-approval of Services.

            The Audit Committee is required to pre-approve audit and non-audit
services performed by the independent auditor in order to assure that the
provision of such services do not impair the auditor's independence.  Unless a
type of service to be provided by the independent auditor has received general
pre-approval, it will require specific pre-approval by the Audit Committee.  Any
proposed services exceeding pre-approved cost levels will require specific pre-
approval by the Audit Committee.

            Certain services have the general pre-approval of the Audit
Committee.  The term of the general pre-approval is 12 months from the date of
pre-approval, unless the Audit Committee specifically provides for a different
period.  The Audit Committee will annually review the services that may be
provided by the independent auditor without obtaining specific pre-approval from
the Audit Committee and may grant general pre-approval for such services.  The
Audit Committee will revise the list of general pre-approved services from time
to time, based on subsequent determinations.  The Audit Committee will not
delegate its responsibilities to pre-approve services performed by the
independent auditor to management.

            The Audit Committee has delegated pre-approval authority to its
Chairman.  The Chairman will report any pre-approval decisions to the Audit
Committee at its next scheduled meeting.  The Committee will designate another
member with such pre-approval authority when the Chairman is unavailable.



AUDIT SERVICES

      The annual Audit services engagement terms and fees will be subject to the
specific pre-approval of the Audit Committee.  The Audit Committee must approve
any changes in terms, conditions and fees resulting from changes in audit scope,
registered investment company (RIC) structure or other matters.

      In addition to the annual Audit services engagement specifically approved
by the Audit Committee, the Audit Committee may grant general pre-approval for
other Audit Services, which are those services that only the independent auditor
reasonably can provide.  The Audit Committee has pre-approved certain Audit
services, all other Audit services must be specifically pre-approved by the
Audit Committee.



AUDIT-RELATED SERVICES

      Audit-related services are assurance and related services that are
reasonably related to the performance of the audit or review of the Company's
financial statements or that are traditionally performed by the independent
auditor.  The Audit Committee believes that the provision of Audit-related
services does not impair the independence of the auditor, and has pre-approved
certain Audit-related services, all other Audit-related services must be
specifically pre-approved by the Audit Committee.



TAX SERVICES

      The Audit Committee believes that the independent auditor can provide Tax
services to the Company such as tax compliance, tax planning and tax advice
without impairing the auditor's independence.  However, the Audit Committee will
not permit the retention of the independent auditor in connection with a
transaction initially recommended by the independent auditor, the purpose of
which may be tax avoidance and the tax treatment of which may not be supported
in the Internal Revenue Code and related regulations.  The Audit Committee has
pre-approved certain Tax services, all Tax services involving large and complex
transactions must be specifically pre-approved by the Audit Committee.



ALL OTHER SERVICES

      With respect to the provision of services other than audit, review or
attest services the pre-approval requirement is waived if:



      (1)         The aggregate amount of all such services provided constitutes
                  no more than five percent of the total amount of revenues paid
                  by the registrant, the registrant's adviser (not including any
                  sub-adviser whose role is primarily portfolio management and
                  is subcontracted with or overseen by another investment
                  adviser), and any entity controlling, controlled by, or under
                  common control with the investment adviser that provides
                  ongoing services to the registrant to its accountant during
                  the fiscal year in which the services are provided;
      (2)         Such services were not recognized by the registrant, the
                  registrant's adviser (not including any sub-adviser whose role
                  is primarily portfolio management and is subcontracted with or
                  overseen by another investment adviser), and any entity
                  controlling, controlled by, or under common control with the
                  investment adviser that provides ongoing services to the
                  registrant  at the time of the engagement to be non-audit
                  services; and
      (3)         Such services are promptly brought to the attention of the
                  Audit Committee of the issuer and approved prior to the
                  completion of the audit by the Audit Committee or by one or
                  more members of the Audit Committee who are members of the
                  board of directors to whom authority to grant such approvals
                  has been delegated by the Audit Committee.


      The Audit Committee may grant general pre-approval to those permissible
non-audit services classified as All Other services that it believes are routine
and recurring services, and would not impair the independence of the auditor.



      The SEC's rules and relevant guidance should be consulted to determine the
precise definitions of prohibited non-audit services and the applicability of
exceptions to certain of the prohibitions.



PRE-APPROVAL FEE LEVELS

      Pre-approval fee levels for all services to be provided by the independent
auditor will be established annually by the Audit Committee.  Any proposed
services exceeding these levels will require specific pre-approval by the Audit
Committee.



PROCEDURES

      Requests or applications to provide services that require specific
approval by the Audit Committee will be submitted to the Audit Committee by both
the independent auditor and the Principal Accounting Officer and/or Internal
Auditor, and must include a joint statement as to whether, in their view, the
request or application is consistent with the SEC's rules on auditor
independence.

            committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
            Regulation S-X, 0% and 0% respectively.

            to the registrant that were approved by the registrants audit
            committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
            Regulation S-X, 0% and 0% respectively.



            4(d)

                  Fiscal year ended 2006 - 0%

            Percentage of services provided to the registrants investment
            adviser and any entity controlling, controlled by, or under common
            control with the investment adviser that provides ongoing services
            to the registrant that were approved by the registrants audit

            Regulation S-X, 0% and 0% respectively.



(f)   NA


(g)   Non-Audit Fees billed to the registrant, the registrant's investment
      adviser, and certain entities controlling, controlled by or under common
      control with the investment adviser:


            Fiscal year ended 2007 - $155,919

            Fiscal year ended 2006 - $185,579



(h)         The registrant's Audit Committee has considered that the provision
of non-audit services that were rendered to the registrant's adviser (not
including any sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by another investment adviser), and any entity
controlling, controlled by, or under common control with the investment adviser
that provides ongoing services to the registrant that were not pre-approved
pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible
with maintaining the principal accountant's independence.
