Management's Discussion of Fund Performance (unaudited)

The total return of Federated U.S. Government Securities Fund: 1-3 Years (the “Fund”), based on net asset value for the 12-month reporting period ended February 28, 2015, was -0.26% for the Institutional Shares, -0.59% for the Service Shares and -0.11% for the Class Y Shares. The -0.11% total return of the Class Y Shares consisted of 0.93% in taxable dividends and 1.04% of price depreciation in the net asset value of the shares. The BofA Merrill Lynch 1-3 Year Treasury Index (BAML1-3T),¹ the Fund's broad-based securities market index, returned 0.66% for the same period. The total return of the Morningstar Short Government Funds Average (MSGFA),² a peer group average for the Fund, was 0.83% for the same period. The Fund's and the MSGFA's total returns for the most recently completed fiscal year reflected actual cash flows, transaction costs and other expenses, which were not reflected in the total return of the BAML1-3T.

During the reporting period, the Fund's investment strategy focused on: (a) duration;³ (b) yield curve positioning; and (c) security selection. These were the most significant factors affecting the Fund's performance relative to the BAML1-3T.

The following discussion will focus on the performance of the Fund's Class Y Shares.

MARKET OVERVIEW

During the reporting period, interest rates declined across the U.S. Treasury curve. Three-year Treasury notes fell from 0.67% on February 28, 2014 to 0.61% on February 28, 2015.⁴

During the reporting period, domestic economic growth accelerated and labor market conditions improved. The Federal Reserve stopped its purchase of Treasury notes and bonds, and expressed a process to begin normalizing overnight interest rates. Confidence in the improving economic fundamentals and outlook continued throughout the reporting period. However, geopolitical events such as military conflict in Ukraine/Russia and the Middle East increased demand for Treasury securities. Global inflation expectations dropped due to weakness in European economies and falling commodity prices. These conditions also increased demand for Treasury securities, particularly longer maturity bonds.

Duration

The Fund had less interest rate risk (i.e., a shorter average duration) than the BAML1-3T for much of the reporting period, anticipating that interest rates would rise, due to improving economic fundamentals and a less supportive monetary policy. The Fund's dollar-weighted average duration at the end of the reporting period was 1.6 years versus the BAML1-3T at 1.9 years. Duration was

adjusted multiple times during the reporting period, but generally was defensively positioned for the entire reporting period. The Fund's defensive duration position subtracted from Fund performance.

Yield Curve

The Fund was underweight shorter maturity bonds and overweight longer maturity bonds with respect to its maturity range. Longer maturity bonds outperformed shorter maturity bonds during the reporting period. Low inflation and geopolitical events caused the long end to rally. The flatter curve positioning helped Fund performance versus the BAML1-3T.

SECURITY SELECTION

The Fund had positions outside of the BAML1-3T in Treasury Inflation-Protected Securities (TIPS), agency debt and agency mortgage-backed securities (MBS).⁵ TIPS underperformed due to the global drop in inflation expectations and fall in commodity prices. Agency debt spreads were stable. MBS lagged in the latter part of the reporting period due to the decline in interest rates and increased volatility of global events. On the whole, security selection subtracted from the Fund's performance.

1	Please see the footnotes to the line graph under “Fund Performance and Growth of a $10,000 Investment” below for the definition of, and more information about, the BAML1-3T.
2	Please see the footnotes to the line graph under “Fund Performance and Growth of a $10,000 Investment” below for the definition of, and more information about, the MSGFA.
3	Duration is a measure of a security's price sensitivity to changes in interest rates. Securities with longer durations are more sensitive to changes in interest rates than other securities of shorter durations.
4	Bond prices are sensitive to changes in interest rates, and a rise in interest rates can cause a decline in their prices.
5	The value of some mortgage-backed securities may be particularly sensitive to changes in the prevailing interest rates, and although the securities are generally supported by some form of government or private insurance, there is no assurance that private guarantors or insurers will meet their obligations.

Performance data quoted represents past performance which is no guarantee of future results. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Mutual fund performance changes over time and current performance may be lower or higher than what is stated. For current to the most recent month-end performance and after-tax returns, visit FederatedInvestors.com or call 1-800-341-7400. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Mutual funds are not obligations of or guaranteed by any bank and are not federally insured.

1	The Fund's performance assumes reinvestment of all dividends and distributions. The BAML1-3T and the MSGFA have been adjusted to reflect reinvestment of dividends on securities in the index and average.
2	The BAML1-3T is an unmanaged index tracking short-term government securities with maturities between 1 and 2.99 years. This index is produced by Bank of America Merrill Lynch, Pierce, Fenner & Smith, Inc. The index is not adjusted to reflect sales loads, expenses or other fees that the Securities and Exchange Commission requires to be reflected in the Fund's performance. The index is unmanaged and, unlike the Fund, is not affected by cash flows. It is not possible to invest directly in an index.
3	Morningstar figures represent the average of the total returns reported by all the mutual funds designated by Morningstar as falling into the respective category indicated. They do not reflect sales charges.

2	Based upon net unrealized appreciation (depreciation) or value of the derivative contracts as applicable. Derivative contracts may consist of futures, forwards, options and swaps. The impact of a derivative contract on the Fund's performance may be larger than its unrealized appreciation (depreciation) or value may indicate. In many cases, the notional value or amount of a derivative contract may provide a better indication of the contract's significance to the portfolio. More complete information regarding the Fund's direct investments in derivative contracts, including unrealized appreciation (depreciation), value and notional values or amounts of such contracts, can be found in the table at the end of the Portfolio of Investments included in this Report.

4	Cash Equivalents include any investment in money market mutual funds and/or overnight repurchase agreements.
5	Assets, other than investments in securities and derivative contracts, less liabilities. See Statement of Assets and Liabilities.
6	For callable investments, “effective maturity” is the unexpired period until the earliest date the investment is subject to prepayment or repurchase by the issuer (and market conditions indicate that the issuer will prepay or repurchase the investment). For all other investments, “effective maturity” is the unexpired period until the final maturity.

Notes to Financial Statements

February 28, 2015

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, 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 U.S. generally accepted accounting principles (GAAP).

Investment Valuation

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 Fund's Board of Trustees (the “Trustees”).
■	Fixed-income securities and repurchase agreements 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), unless the issuer's creditworthiness is impaired or other factors indicate that amortized cost is not an accurate estimate of the investment's fair value, in which case it would be valued in the same manner as a longer-term security.
■	Shares of other mutual funds or non-exchange-traded investment companies are valued based upon their reported NAVs.
■	Derivative contracts listed on exchanges are valued at their reported settlement or closing price, except that options are valued at the mean of closing bid and asked quotations.
■	Over-the-counter (OTC) derivative contracts are fair valued using price evaluations provided by a pricing service approved by Trustees.
■	For securities that are fair valued in accordance with procedures established by and under the general supervision of the Trustees, certain factors may be considered such as: the last traded or purchase price of the security, information obtained by contacting the issuer or dealers, analysis of the issuer's financial statements or other available documents, fundamental analytical data, the nature and duration of restrictions on disposition, the movement of the market in which the security is normally traded, public trading in similar securities or derivative contracts of the issuer or comparable issuers, movement of a relevant index or other factors including, but not limited to, industry changes and relevant government actions.

If any price, quotation, price evaluation or other pricing source is not readily available when the NAV is calculated, or if the Fund cannot obtain price evaluations from a pricing service or from more than one dealer for an investment within a reasonable period of time as set forth in the Fund's valuation policies and procedures, 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 obtain the fair value assigned to an investment if it sold the investment at approximately the time at which the Fund determines its NAV per share.

Annual Shareholder Report

15

Fair Valuation Procedures

The Trustees have ultimate responsibility for determining the fair value of investments for which market quotations are not readily available. The Trustees have appointed a valuation committee (“Valuation Committee”) comprised of officers of the Fund, Federated Investment Management Company (“Adviser”) and certain of the Adviser's affiliated companies to assist in determining fair value and in overseeing the calculation of the NAV. The Trustees have 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. The Valuation Committee employs various methods for reviewing third-party pricing-service evaluations including periodic reviews of third-party pricing services' policies, procedures and valuation methods (including key inputs, methods, models and assumptions), transactional back-testing, comparisons of evaluations of different pricing services and review of price challenges by the Adviser based on recent market activity. 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 Trustees. The Trustees periodically review and approve the fair valuations made by the Valuation Committee and any changes made to the procedures.

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. 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 any U.S. Treasury and Agency securities, mortgage-backed securities and municipal securities. The Fund normally uses mid evaluations for any other types of fixed-income securities and any OTC derivative contracts. In the event that market quotations and price evaluations are not available for an investment, the fair value of the investment is determined in accordance with procedures adopted by the Trustees.

Repurchase Agreements

The Fund may invest in repurchase agreements for short-term liquidity purposes. 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.

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.

Annual Shareholder Report

16

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.

Repurchase agreements are subject to Master Netting Agreements which are agreements between the Fund and its counterparties that provide for the net settlement of all transactions and collateral with the Fund, through a single payment, in the event of default or termination. Amounts presented on the Portfolio of Investments and Statement of Assets and Liabilities are not net settlement amounts but gross. As indicated above, the cash or securities to be repurchased, as shown on the Portfolio of Investments, exceeds the repurchase price to be paid under the agreement reducing the net settlement amount to zero.

Investment Income, Gains and Losses, Expenses and Distributions

Investment transactions are accounted for on a trade-date basis. Realized gains and losses from investment transactions are recorded on an identified-cost basis. Interest income and expenses are accrued daily. Dividend income and distributions to shareholders are recorded on the ex-dividend date. Positive or negative inflation adjustments on Treasury Inflation-Protected Securities (TIPS) 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 Institutional Shares and Service Shares may bear distribution services fees and other service fees unique to those classes.

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.

Other Service Fees

The Fund may pay other service fees up to 0.25% of the average daily net assets of the Fund's Institutional Shares and Service Shares to unaffiliated financial intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Subject to the terms described in the Expense Limitation note, FSSC may voluntarily reimburse the Fund for other service fees. For the year ended February 28, 2015, other service fees for the Fund were as follows:

	Other Service Fees Incurred
Institutional Shares	$174,286
Service Shares	35,701
TOTAL	$209,987

Premium and Discount Amortization

All premiums and discounts on fixed-income securities are amortized/accreted using the effective-interest-rate method.

Annual Shareholder Report

17

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. As of and during the year ended February 28, 2015, the Fund did not have a liability for any uncertain tax positions. The Fund recognizes interest and penalties, if any, related to tax liabilities as income tax expense in the Statement of Operations. As of February 28, 2015, tax years 2012 through 2015 remain subject to examination by the Fund's major tax jurisdictions, which include the United States of America and the Commonwealth of Massachusetts.

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.

Futures Contracts

The Fund purchases and sells financial futures contracts to manage duration and yield curve risks. Upon entering into a financial futures contract with a broker, the Fund is required to deposit in a segregated account a specified amount of cash or U.S. government securities. Futures contracts are valued daily and unrealized gains or losses are recorded in a “variation margin” account. Daily, the Fund receives from or pays to the broker a specified amount of cash based upon changes in the variation margin account. When a contract is closed, the Fund recognizes a realized gain or loss. Futures contracts have market risks, including the risk that the change in the value of the contract may not correlate with the changes in the value of the underlying securities. There is minimal counterparty risk to the Fund since futures are exchange traded and the exchange's clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default.

Futures contracts outstanding at period end are listed after the Fund's Portfolio of Investments.

The average notional value of long and short futures contracts held by the Fund throughout the period was $22,905,463 and $85,234,195, respectively. This is based on amounts held as of each month-end throughout the fiscal period.

Option Contracts

The Fund buys or sells put and call options to increase income and return, and to manage duration and yield curve risks. The seller (“writer”) of an option receives a payment or premium, from the buyer, which the writer keeps regardless of whether the buyer exercises the option. When the Fund writes a put or call option, an amount equal to the premium received is recorded as a liability and subsequently marked to market to reflect the current value of the option written. Premiums received from writing options which expire are treated as realized gains. The Fund, as a writer of an option, bears the market risk of an unfavorable change in the price of the underlying reference instrument. When the Fund purchases a put or call option, an amount equal to the premium paid is recorded as an increase to the cost of the investment and subsequently marked to market to reflect the current value of the option purchased. Premiums paid for purchasing options which expire are treated as realized losses. Premiums received/paid for writing/purchasing options which are exercised or closed are

Annual Shareholder Report

18

added to the proceeds or offset against amounts paid on the underlying reference instrument to determine the realized gain or loss. The risk associated with purchasing put and call options is limited to the premium paid. Options can trade on securities or commodities exchanges. In this case, the exchange sets all the terms of the contract except for the price. Most exchanges require investors to maintain margin accounts through their brokers to cover their potential obligations to the exchange. This protects investors against potential defaults by the counterparty.

The following is a summary of the Fund's written option activity:

Contracts	Number of Contracts	Premium
Outstanding at 2/28/2014	—	$—
Contracts written	1,765	565,562
Contracts bought back	(1,765)	(565,562)
Outstanding at 2/28/2015	—	$—

The average market value of written options held by the Fund throughout the period was $15,986. This is based on amounts held as of each month-end throughout the fiscal period.

The average market value of purchased options held by the Fund throughout the period was $28,085. This is based on amounts held as of each month-end throughout the fiscal period.

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 borrower of the security, 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, 2015, the Fund had no outstanding securities on loan.

Other

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. The Fund applies Investment Company accounting and reporting guidance.

4. FEDERAL TAX INFORMATION

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences are due to differing treatments for TIPS deflation adjustments and expiration of capital loss carryforwards.

For the year ended February 28, 2015, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Paid-In Capital	Undistributed Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss)
$(264,152)	$192,704	$71,448

Net investment income (loss), net realized gains (losses), and net assets were not affected by this reclassification.

The tax character of distributions as reported on the Statement of Changes in Net Assets for the years ended February 28, 2015 and 2014, was as follows:

	2015	2014
Ordinary income	$2,540,786	$2,016,306

Annual Shareholder Report

21

As of February 28, 2015, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$204,824
Net unrealized appreciation	$1,271,099
Capital loss carryforwards and deferrals	$(8,965,710)

At February 28, 2015, the cost of investments for federal tax purposes was $259,734,707. The net unrealized appreciation of investments for federal tax purposes excluding any unrealized depreciation resulting from futures contracts was $1,271,099. This consists entirely of net unrealized appreciation from investments for those securities having an excess of value over cost of $1,271,099.

At February 28, 2015, the Fund had a capital loss carryforward of $8,488,498 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, thereby reducing 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, a net capital loss incurred in taxable years beginning on or before December 22, 2010, is characterized as short-term and may be carried forward for a maximum of eight tax years (“Carryforward Limit”), whereas a net capital loss incurred in taxable years beginning after December 22, 2010, retains its character as either short-term or long-term, does not expire and is required to be utilized prior to the losses which have a Carryforward Limit.

The following schedule summarizes the Fund's capital loss carryforwards and expiration years:

Expiration Year	Short-Term	Long-Term	Total
No Expiration	$7,758,243	$730,255	$8,488,498

Capital loss carryforwards of $264,152 expired during the year ended February 28, 2015.

As of February 28, 2015, for federal income tax purposes, the Fund had $477,212 in straddle loss deferrals.

5. INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Adviser Fee

The advisory agreement between the Fund and the Adviser provides for an annual fee equal to 0.30% of the Fund's average daily net assets. Subject to the terms described in the Expense Limitation note, the Adviser may voluntarily choose to waive any portion of its fee. For the year ended February 28, 2015, the Adviser voluntarily waived $518,238 of its fee.

Annual Shareholder Report

22

Administrative Fee

Federated Administrative Services (FAS), under the Administrative Services Agreement, provides the Fund with administrative personnel and services. For purposes of determining the appropriate rate breakpoint, “Investment Complex” is defined as all of the Federated Funds subject to a fee under the Administrative Services Agreement. The fee paid to FAS is based on the average daily net assets of the Investment Complex as specified below, plus certain out-of-pocket expenses:

Administrative Fee	Average Daily Net Assets of the Investment Complex
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

Subject to the terms described in the Expense Limitation note, FAS may voluntarily choose to waive any portion of its fee. For the year ended February 28, 2015, the annualized fee paid to FAS was 0.078% of average 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 Service Shares to finance activities intended to result in the sale of these shares. The Plan provides that the Fund may incur distribution expenses at 0.25% of average daily net assets, annually, to compensate FSC. Subject to the terms described in the Expense Limitation note, FSC may voluntarily choose to waive any portion of its fee. For the year ended February 28, 2015, distribution services fees for the Fund were as follows:

	Distribution Services Fees Incurred
Service Shares	$36,009

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, 2015, FSC retained the entire distribution services fee paid by the Fund.

Other Service Fees

For the year ended February 28, 2015, FSSC received $1,911 of the other service fees disclosed in Note 2.

Expense Limitation

The Adviser and certain of its affiliates (which may include FSC, FAS and FSSC) on their own initiative have agreed to waive certain amounts of their respective fees and/or reimburse expenses. Total annual fund operating expenses (as shown in the financial highlights, excluding extraordinary expenses and proxy-related expenses paid by the Fund, if any) paid by the Fund's Institutional Shares, Service Shares and Class Y Shares (after the voluntary waivers and/or reimbursements) will not exceed 0.47%, 0.80% and 0.30% (the “Fee Limit”), respectively, up to but not including the later of (the “Termination Date”): (a) May 1, 2016; or (b) the date of

Annual Shareholder Report

23

the Fund's next effective Prospectus. While the Adviser and its applicable 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 Trustees.

General

Certain Officers and Trustees of the Fund are Officers and Directors or Trustees of certain of the above companies. To efficiently facilitate payment, Directors'/Trustees' fees and certain expenses related to conducting meetings of the Directors/Trustees and other miscellaneous expenses are paid by an affiliate of the Adviser which in due course are reimbursed by the Fund. Such expenses may be included in Accrued and Miscellaneous Expenses on the Statement of Assets and Liabilities and Statement of Operations, respectively.

6. LINE OF CREDIT

The Fund participates in a $100,000,000 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 offered to the Fund by PNC Bank at the time of the borrowing. As of February 28, 2015, there were no outstanding loans. During the year ended February 28, 2015, the Fund did not utilize the LOC.

7. INTERFUND LENDING

Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other funds advised by subsidiaries of Federated Investors, Inc., may participate in an interfund lending program. This program provides an alternative credit facility allowing the Fund to borrow from other participating affiliated funds. As of February 28, 2015, there were no outstanding loans. During the year ended February 28, 2015, the program was not utilized.

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, 2015, 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 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, 2015, by correspondence with the custodian and others. 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, 2015, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Shareholder Expense Example (unaudited)

As a shareholder of the Fund, you incur ongoing costs, including management fees and to the extent applicable, distribution (12b-1) fees and/or other service 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, 2014 to February 28, 2015.

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.

Actual:
Institutional Shares	$1,000	$1,000.00	$2.28
Service Shares	$1,000	$998.40	$3.96
Class Y Shares	$1,000	$1,000.80	$1.49
Hypothetical (assuming a 5% return before expenses):
Institutional Shares	$1,000	$1,022.51	$2.31

Evaluation and Approval of Advisory Contract–May 2014

Federated U.S. Government Securities Fund: 1-3 Years (the “Fund”)

Following a review and recommendation of approval by the Fund's independent trustees, the Fund's Board reviewed and approved at its May 2014 meetings the Fund's investment advisory contract for an additional one-year term. The Board's decision regarding the contract reflects the exercise of its business judgment on whether to continue the existing arrangements.

In this connection, the Federated Funds' Board had previously appointed 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 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 (the “Evaluation”). The Board considered that Evaluation, along with other information, in deciding to approve the advisory contract.

The Board is also familiar with and considered 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 to a fund and its shareholders, including the performance and expenses of the fund and of comparable funds; the Adviser's cost of providing the services, including the profitability to the Adviser of providing advisory services to a fund; the extent to which the Adviser may realize “economies of scale” as a fund grows larger and, if such economies exist, whether they have been shared with a fund and its shareholders or the family of funds; any “fall-out financial benefits” that accrue to the Adviser because of its relationship with a fund (including research services received from brokers that execute fund trades and any fees paid to affiliates of the Adviser for services rendered to a fund); comparative fee structures, including a comparison of fees paid to the Adviser with those paid by similar funds; and the extent of care, conscientiousness and independence with which the Board members perform their duties and their expertise, including whether they are fully informed about all facts the Board deems relevant to its consideration of the Adviser's services and fees. The Board noted that SEC disclosure requirements regarding the basis for the Board's approval of the Fund's advisory contract generally track the factors listed above. Consistent with these judicial decisions and SEC disclosure requirements, the Board also considered management fees charged to

33

institutional and other clients of the Adviser for what might be viewed as like services. The Board was aware of these factors and was guided by them in its review of the Fund's advisory contract to the extent it considered them to be 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 independent legal counsel. Throughout the year, and in connection with its May meetings, the Board requested and received substantial and detailed information about the Fund and the Federated organization that was in addition to the extensive materials that comprise and accompany the Senior Officer's Evaluation. Federated provided much of this information at each regular meeting of the Board, and furnished additional substantial information in connection with the May meeting at which the Board's formal review of the advisory contract occurred. At this May meeting, senior management of the Adviser also met with the independent trustees and their counsel to discuss the materials presented and any other matters thought relevant by the Adviser or the trustees. Between regularly scheduled meetings, the Board also 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 information 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); and the nature, quality and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates. The Board also considered the preferences and expectations of Fund shareholders; the entrepreneurial risk assumed by the Adviser in sponsoring the funds; 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.

While mindful that courts have cautioned against giving such comparisons too much weight, the Board has found the use of comparisons of the Fund's fees and expenses to other mutual funds with comparable investment programs to be relevant. In this regard, the Board was presented with, and considered, information regarding the contractual advisory fee rates, net advisory fee rates and total expense ratios relative to a fund's peers. The Board focused on comparisons with other similar mutual funds more heavily than non-mutual fund products or services because it is believed that 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 relevant indicator of what consumers have found to be reasonable in the precise marketplace in which the Fund competes.

The Board reviewed the contractual advisory fee rate, net advisory fee rate where partially waived and other expenses of the Fund and noted the position of the Fund's fee rates relative to its peers. In this regard, the Board noted that the contractual advisory fee rate was below the median of the relevant peer group and that it was satisfied that the overall expense structure of the Fund remained competitive.

By contrast, 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 and sub-adviser services). He concluded that mutual funds and institutional accounts are inherently different products. Those differences include, but are not limited to, different types of targeted investors; being subject to different laws and regulations; different legal structures; different average account sizes and portfolio management techniques made necessary by different cash flows and different associated costs; and the time spent by portfolio managers and their teams, funds financial services, legal, compliance and risk management in reviewing securities pricing, addressing different administrative responsibilities, addressing different degrees of risk associated with management and a variety of different costs. The Senior Officer did not consider these fee schedules to be determinative in judging the appropriateness of mutual fund advisory fees.

The Fund's ability to deliver competitive performance when compared to its peer group was also deemed to be relevant by the Board as a useful indicator of how the Adviser is executing the Fund's investment program, which in turn was one of the Board's considerations 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.

Annual Shareholder Report

35

The Senior Officer reviewed information compiled by Federated, using data supplied by independent fund ranking organizations, regarding the performance of, and fees charged by, other mutual funds, noting his view that comparisons to fund peer groups may be helpful, though not conclusive, in judging the reasonableness of proposed fees. The Board considered, in evaluating such comparisons, that in some cases individual funds may exhibit significant and unique differences in their objectives and management techniques when compared to other funds within an industry peer group.

For the periods covered by the Evaluation, 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 and five-year periods. 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 in the context of the other factors considered relevant by the Board.

The Board also received financial information about Federated, including information regarding the compensation and benefits Federated derived from its relationships with the Federated funds. This information 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 information also detailed any indirect benefit Federated may derive from its receipt of research services from brokers who execute Federated fund trades. In addition, the Board considered the fact that, in order for a fund to be competitive in the marketplace, Federated and its affiliates frequently waived fees and/or reimbursed expenses and have disclosed to fund investors and/or indicated to the Board their intention to do so in the future, where appropriate. Moreover, the Board receives regular reporting as to the institution, adjustment or elimination of these voluntary waivers. In addition, following discussions regarding the Senior Officer's May 2013 recommendations, Federated made meaningful reductions to gross advisory fees for several funds.At the Board meeting in May 2014, the Senior Officer proposed, and the Board approved, reductions in the contractual advisory fees of certain other funds.

Federated furnished information, 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, while these cost allocation reports apply consistent allocation processes, the inherent difficulties in allocating costs continues to cause the Senior Officer to question the precision of the process and to conclude that such reports may be unreliable, since a single change in an allocation estimate may dramatically alter the resulting estimate of cost and/or profitability of a fund and may produce unintended consequences. The allocation information, including the Senior Officer's view that fund-by-fund estimations may be unreliable, was considered in the analysis by the Board.

36

The Board and the Senior Officer also reviewed information compiled by Federated comparing profitability information for Federated to other publicly held fund management companies. In this regard, the Senior Officer 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 and long-term investments in areas that support all of the Federated family of funds, such as personnel and processes for the portfolio management, shareholder services, compliance, internal audit, and risk management functions; and systems technology; and that the benefits of these efforts (as well as any economies, should they exist) were likely to be enjoyed by the fund family as a whole. Finally, the Board also noted the absence of any applicable regulatory or industry guidelines on this subject, which (as discussed in the Senior Officer's Evaluation) 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 noted that, subject to the comments and recommendations made within his Evaluation, his observations and the information accompanying the Evaluation supported a finding by the Board that the management fees for each of the funds were reasonable. Under these circumstances, no changes were recommended to, and no objection was raised to, the continuation of the Fund's advisory contract.

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 many shareholders have invested in the Fund on the strength of the Adviser's industry standing and reputation and with 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 concluded that, in light of the factors discussed above, including the nature, quality and scope of the services provided to the Fund by the Adviser and its affiliates, continuation of the advisory contract was appropriate.

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 necessarily relevant to the 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.

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.
