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 March 1, 2005 to August 31, 2005.

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 provided to enable you to compare the ongoing costs of investing in the Fund and 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.

Notes to Financial Statements

August 31, 2005 (unaudited)

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 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

The Fund generally values fixed income securities according to prices furnished by the independent service, except that fixed income securities with remaining maturities of less than 60 days at the time of purchase may be valued at amortized cost. The Fund generally values short-term securities according to prices furnished by an independent pricing service, except that short-term securities with remaining maturities of less than 60 days at the time of purchase may be valued at amortized cost. Prices furnished by an independent pricing service are intended to be indicative of the mean between the bid and asked prices currently offered to institutional investors for the securities. Securities for which no quotations are readily available are valued at fair value as determined in accordance with procedures established by and under general supervision of the Board of Trustees (the "Trustees").

Repurchase Agreements

It is the policy of the Fund to require the custodian bank to take possession, to have legally segregated in the Federal Reserve Book Entry System, or to have segregated within the custodian bank's vault, all securities held as collateral under repurchase agreement transactions. Additionally, procedures have been established by the Fund to monitor, on a daily basis, the market value of each repurchase agreement's collateral to ensure that the value of the collateral at least equals the repurchase price to be paid under the repurchase agreement.

The Funds will only enter into repurchase agreements with banks and other recognized financial institutions, such as broker/dealers, which are deemed by the Fund's adviser to be creditworthy pursuant to the guidelines and/or standards reviewed or established by the Trustees. Risks may arise from the potential inability of counterparties to honor the terms of the repurchase agreement. The Fund, along with other affiliated investment companies, may utilize a joint trading account for the purpose of entering into one or more repurchase agreements.

Investment Income, Gains and Losses, Expenses and Distributions

Interest income and expenses are accrued daily. Dividend income and distributions to shareholders are recorded on the ex-dividend date. Distributions of net investment income are declared daily and paid monthly. Non-cash dividends included in dividend income, if any, are recorded at fair value. 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.

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 corporate bonds, equity and 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 102% 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 August 31, 2005, securities subject to this type of arrangement and related collateral were as follows:

Market Value of
Securities Loaned
   
 Market Value
of Collateral
$176,115,734
$179,415,000

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

At August 31, 2005, the cost of investments for federal tax purposes was $552,056,855. The net unrealized appreciation of investments for federal tax was $75,746. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $514,755 and net unrealized depreciation from investments for those securities having an excess of cost over value of $439,009.

At February 28, 2005, the Fund had a capital loss carryforward of $4,169,892 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 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

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. The Adviser may voluntarily choose to waive any portion of its fee. The Adviser can modify or terminate this voluntary waiver at any time at its sole discretion. For the six months ended August 31, 2005, the Adviser voluntarily waived $587,698 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 all Federated funds as specified below:

Maximum
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. FAS may voluntarily choose to waive any portion of its fee. FAS can modify or terminate this voluntary waiver at any time at its sole discretion. For the six months ended August 31, 2005, 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. FSC may voluntarily choose to waive any portion of its fee. FSC can modify or terminate this voluntary waiver at any time at its sole discretion. Rather than paying investment professionals directly, the Fund may pay fees to FSC and FSC will use the fees to compensate investment professionals. For the six months ended August 31, 2005, FSC retained $57,108 of fees paid by the Fund.

Shareholder Services Fee

The Fund may pay fees (Services Fees) up to 0.25% of the average daily net assets of the Fund's Institutional Shares and Institutional Service Shares to financial institutions or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated Investors, Inc., for providing services to shareholders and maintaining shareholder accounts. Under certain agreements, rather than paying financial institutions directly, the Fund may pay Service Fees to FSSC and FSSC will use the fees to compensate financial institutions. FSSC or these financial institutions may voluntarily choose to waive any portion of their fee. This voluntary waiver can be modified or terminated at any time. For the six months ended August 31, 2005, FSSC voluntarily waived $15,499 of its fee. For the six months ended August 31, 2005, FSSC retained $45,567 of fees paid by the Fund. For the six months ended August 31, 2005, the Fund's Class Y Shares did not incur a shareholder services fee.

General

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

6. 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. 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 Morin & Oshinsky LLP to represent the Funds in these lawsuits. Federated and the Funds, and their respective counsel, are reviewing the allegations and will respond appropriately. 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.

Board Review of Advisory Contract

As required by the 1940 Act, the Fund's Board has reviewed the Fund's investment advisory contract. The Board's decision to approve the contract reflects the exercise of its business judgment on whether to continue the existing arrangements. During its review of the contract, the Board considers many factors, among the most material of which are: the Fund's investment objectives; the Adviser's management philosophy, personnel, processes, and investment and operating strategies; long-term performance; the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry; the range of comparable fees for similar funds in the mutual fund industry; the range and quality of services provided to the Fund and its shareholders by the Federated organization in addition to investment advisory services; and the Fund's relationship to the Federated family of funds.

In its decision to appoint or renew an Adviser, the Board is 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 recognizes 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 "selection" or approval of the Adviser must reflect the fact that it is the shareholders who have effectively selected the Adviser by virtue of having invested in the Fund. The Board also considers the compensation and benefits received by the Adviser. This includes 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 fund trades, as well as advisory fees. In this regard, the Board is aware that various courts have interpreted provisions of the 1940 Act and have indicated in their decisions 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 bearing on the Adviser's service and fee. The Fund's Board is aware of these factors and is 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 considers and weighs 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 is assisted in its deliberations by the advice of independent legal counsel. In this regard, the Board requests and receives substantial and detailed information about the Fund and the Federated organization. Federated provides much of this information at each regular meeting of the Board, and furnishes additional reports in connection with the particular meeting at which the Board's formal review of the advisory contract occurs. In between regularly scheduled meetings, the Board may receive information on particular matters as the need arises. Thus, the Board's evaluation of an advisory contract is informed by reports covering such matters as: the Adviser's investment philosophy, personnel, and processes; 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 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; the nature and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates; 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 evaluation process is evolutionary, reflecting continually developing considerations. 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 focuses on comparisons with other similar mutual funds (rather 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 already chosen 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 may be a useful indicator of how the Adviser is executing on the Fund's investment program, which would in turn assist the Board in reaching a conclusion that the nature, extent, and quality of the Adviser's investment management services are such as to warrant continuation of the advisory contract.

The Board also receives financial information about Federated, including reports on the compensation and benefits Federated derives from its relationships with the Federated funds. These reports cover 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 discuss 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 waive fees and/or reimburse expenses. Although the Board considers the profitability of the Federated organization as a whole, it does not evaluate, on a fund-by-fund basis, Federated's "profitability" and/or "costs" (which would include an assessment as to whether "economies of scale" would be realized if the fund were to grow to some sufficient size). In the Board's view, the cost of performing advisory services on a fund-specific basis is both difficult to estimate satisfactorily and a relatively minor consideration in its overall evaluation. Analyzing isolated funds would require constructed allocations of the costs of shared resources and operations based on artificial assumptions that are inconsistent with the existing relationships within a large and diversified family of funds that receive advisory and other services from the same organization. Although the Board is always eager to discover any genuine "economies of scale," its experience has been that such "economies" are likely to arise only when a fund grows dramatically, and becomes and remains very large in size. Even in these instances, purchase and redemption activity, as well as the presence of expense limitations (if any), may offset any perceived economies. As suggested above, the Board considers the information it receives about the Fund's performance and expenses as compared to an appropriate set of similar competing funds to be more relevant.

The Board bases its decision to approve an 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 are relevant to every Federated fund, nor does the Board consider any one of them to be determinative. With respect to the factors that are relevant, the Board's decision to approve the contract reflects its determination that Federated's performance and actions provide a satisfactory basis to support the decision to continue the existing arrangements.

This report is authorized for distribution to prospective investors only when preceded or accompanied by the Fund's prospectus, which contains facts concerning its objective and policies, management fees, expenses, and other information.

IMPORTANT NOTICE ABOUT FUND DOCUMENT DELIVERY

In an effort to reduce costs and avoid duplicate mailings, the Fund(s) intend to deliver a single copy of certain documents to each household in which more than one shareholder of the Fund(s) resides (so-called "householding"), as permitted by applicable rules. The Fund's "householding" program covers its/their Prospectus and Statement of Additional Information, and supplements to each, as well as Semi-Annual and Annual Shareholder Reports and any Proxies or information statements. Shareholders must give their written consent to participate in the "householding" program. The Fund is also permitted to treat a shareholder as having given consent ("implied consent") if (i) shareholders with the same last name, or believed to be members of the same family, reside at the same street address or receive mail at the same post office box, (ii) the Fund gives notice of its intent to "household" at least sixty (60) days before it begins "householding" and (iii) none of the shareholders in the household have notified the Fund(s) or their agent of the desire to "opt out" of "householding." Shareholders who have granted written consent, or have been deemed to have granted implied consent, can revoke that consent and opt out of "householding" at any time: shareholders who purchased shares through an intermediary should contact their representative; other shareholders may call the Fund at 1-800-341-7400.
