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 August 1, 2005 to January 31, 2006.

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.

	Beginning Account Value 8/1/2005	Ending Account Value 1/31/2006	Expenses Paid During Period¹
Actual:
Institutional Shares	$1,000	$1,015.50	$3.25
Institutional Service Shares	$1,000	$1,014.80	$3.91
Hypothetical (assuming a 5% return before expenses):
Institutional Shares	$1,000	$1,021.98	$3.26
Institutional Service Shares	$1,000	$1,021.32	$3.92

1 Expenses are equal to the Fund's annualized net expense ratios, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). The annualized net expense ratios are as follows:

Institutional Shares		0.64%
Institutional Service Shares		0.77%

Management's Discussion of Fund Performance

The fund's total return for the 12-month reporting period was 2.28% for the Institutional Shares and 2.13% for the Institutional Service Shares. The Institutional Shares' total return consisted of 4.77% of taxable dividends and (2.49)% depreciation in the net asset value of the shares. The Lehman Brothers GNMA Index (Index)¹ returned 2.96%. The fund's total return for the most recently completed fiscal year reflected actual cashflows, transaction costs and other expenses not reflected in the total return of the Index.

The fund's investment strategy focused on: (a) selection of securities with advantageous prepayment and value characteristics; and (b) duration.²

For the purposes of the following, the discussion will focus on the performance of the fund's Institutional Shares.

MARKET OVERVIEW

During the 12-month reporting period, interest rates increased across the Treasury security maturity spectrum. Specifically, the two-year and ten-year Treasury yields increased 1.24% and 0.39%, respectively.

Government National Mortgage Association (Ginnie Mae) mortgage-backed securities (MBS) outperformed relative to similar duration U.S. Treasury securities. A lack of supply combined with significant demand resulted in strong performance. As market yields increased, the effective duration--defined as the percentage price change for a 1% change in yields--of MBS increased due to the slowdown in refinancings and prepayments.

SECURITY SELECTION

In most market environments, MBS prepayment risks are of concern due to potential for negative performance impact. Prepayments on premium-priced mortgage securities detract from fund performance when prepaid principal reduces expected yield and proceeds are invested at lower market yields. However, in a rising yield environment where mortgage prices may move from premium to discount prices, prepayments may become beneficial.

1 The Index is an unmanaged index composed of all fixed securities mortgage pools by GNMA, including GNMA Graduated Payment Mortgages. The index is unmanaged and investments cannot be made in an index.

2 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.

For the reporting period, MBS prices declined. Some formerly premium-priced securities moved to par or discount prices, altering prepayment implications. While security selection criteria changed to reflect the changing environment, results were mixed and security selection marginally detracted from fund performance as compared to the Index.

Additionally, robust overseas demand and limited supply drove Ginnie Mae mortgage security valuations to new records. Due to concerns over relative value, the fund added MBS produced under the Ginnie Mae II program MBS instead of the Ginnie Mae I program. Both programs are backed by the full faith and credit of the U.S. government. The programs differ in that all mortgages in the Ginnie Mae I program have the same weighted average coupon³ (WAC), while the Ginnie Mae II program allows for some variation in WAC. The Ginnie Mae I program MBS outperformed the Ginnie Mae II during the year.

DURATION

Throughout the period, a below-Index duration stance was maintained in anticipation of higher interest rates. As interest rates increased during the fiscal year, the strategy positively contributed to the fund's total return as compared to the Index.

3 A "coupon" is the interest rate paid on the face amount of a mortgage.

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 the reinvestment of all dividends and distributions. The LBGNMA and the LGNMAFA have been adjusted to reflect reinvestment of dividends on securities in the index and the average. The LBGNMA 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. The index is unmanaged, and unlike the Fund, is not affected by cashflows. It is not possible to invest directly in an index or average.

2 The LGNMAFA represents the average of the total returns reported by all of the mutual funds designated by Lipper, Inc. as falling in the category indicated. These figures do not reflect sales charges.

Notes to Financial Statements

January 31, 2006

1. ORGANIZATION

Federated GNMA Trust (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 two classes of shares: Institutional Shares and Institutional Service 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 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 and short-term securities according to prices furnished by an independent pricing service, except that securities with remaining maturities of less than 60 days at the time of purchase may be valued at amortized cost. For mortgage-backed securities, prices furnished by the independent pricing service are based on the aggregate investment value of the projected cash flows to be generated by the security. For other fixed-income and short-term securities, 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 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 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. 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/Paydown Gains and Losses

All premiums and discounts on fixed-income securities, other than mortgage-backed securities, are amortized/accreted. Gains and losses realized on principal payments of mortgage-backed securities (paydown gains and losses) are classified as part of investment income.

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.

The Fund may transact in To Be Announced Securities (TBAs). As with other delayed delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms such as issuer, interest rate and terms of underlying mortgages. The Fund records TBA securities on the trade date utilizing information associated with the specified terms of the transaction as opposed to the specific mortgages. TBAs are marked to market daily and begin earning interest on the settlement date. Losses may occur due to the fact that the actual underlying mortgages received may be less favorable than those anticipated by the Fund.

Dollar Roll Transactions

The Fund enters into dollar roll transactions with respect to mortgage securities issued by Government National Mortgage Association (GNMA), in which the Fund sells mortgage securities to financial institutions and simultaneously agrees to accept substantially similar (same type, coupon and maturity) securities at a later date at an agreed-upon price. Dollar roll transactions, which are treated as purchases and sales, will not exceed 12 months. The Fund will use the proceeds generated from the transaction to invest in short-term investments or mortgage-backed securities which may enhance the Fund's current yield and total return.

Information regarding dollar roll transactions for the Fund for the year ended January 31, 2006, was as follows:

Maximum amount outstanding during the period	$	125,919,941
Average amount outstanding during the period¹	$	89,887,340
Average shares outstanding during the period		60,023,897
Average debt per share outstanding during the period	$	1.50

1 The average amount outstanding during the period was calculated by adding the borrowings at the end of the day and dividing the sum by the number of days in the year ended January 31, 2006.

Statement of Cash Flows

Information on financial transactions which have been settled through the receipt or disbursement of cash is presented in the Fund's Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows is the amount reported as cash in the Fund's Statement of Assets and Liabilities and represents cash on hand in its custodian bank account and does not include any short-term investments at January 31, 2006.

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 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 dollar roll adjustments.

For the year ended January 31, 2006, permanent differences identified and reclassified among the components of net assets were as follows:

Increase (Decrease)
Undistributed Net Investment Income		Accumulated Net Realized Losses
$1,608,337		$(1,608,337)

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 January 31, 2006 and 2005, was as follows:

		2006		2005
Ordinary income¹		$31,630,328		$34,058,155

1 For tax purposes short-term capital gain distributions are considered ordinary income distributions.

As of January 31, 2006, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$	1,128,126
Net unrealized appreciation	$	8,559,560
Capital loss carryforward	$	26,231,014

The difference between book-basis and tax-basis net unrealized appreciation/depreciation is attributable in part to differing treatments for dollar roll adjustments and the deferral of losses on wash sales.

At January 31, 2006, the cost of investments for federal tax purposes was $726,826,542. The net unrealized appreciation of investments for federal tax purposes was $8,559,560. This consists of net unrealized appreciation from investments for those securities having an excess of value over cost of $8,981,492 and net unrealized depreciation from investments for those securities having an excess of cost over value of $421,932.

At January 31, 2006, the Fund had a capital loss carryforward of $26,231,014 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		$9,358,296
2010		$ 7,642,119
2012		$ 909,063
2013		$ 7,078,438
2014		$1,243,098

Under current tax regulations, capital losses realized after October 31 may be deferred and treated as occurring on the first day of the following fiscal year. As of January 31, 2006, for federal income tax purposes, post October losses of $3,381,619 were deferred to February 1, 2006.

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 year ended January 31, 2006, the Adviser voluntarily waived $136,871 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:

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 year ended January 31, 2006, 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 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. For the year ended January 31, 2006, FSC voluntarily waived $143,596 of its fee. When FSC receives fees, it may pay some or all of them to financial intermediaries whose customers purchase shares. For the year ended January 31, 2006, FSC did not retain any 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 intermediaries or to Federated Shareholder Services Company (FSSC) for providing services to shareholders and maintaining shareholder accounts. Under certain agreements, rather than paying financial intermediaries directly, the Fund may pay Service Fees to FSSC and FSSC will use the fees to compensate financial intermediaries. FSSC or these financial intermediaries may voluntarily choose to waive any portion of their fee. This voluntary waiver can be modified or terminated at any time. For the year ended January 31, 2006, FSSC voluntarily waived $365,496 of its fee. For the year ended January 31, 2006, FSSC retained $109,401 of fees paid by the Fund.

Commencing on August 1, 2005, and continuing through February 24, 2006, FSSC is reimbursing daily a portion of the shareholder services fee. This reimbursement resulted from an administrative delay in the implementation of contractual terms of shareholder service fee agreements. This reimbursement amounted to $5,888 for the year ended January 31, 2006.

Other

Federated retained an outside law firm to perform an internal review of past mutual fund trading practices and report to a special investigative committee of Federated's Board. In conjunction with this review, the Independent Trustees of the Fund retained a financial expert to assess the impact of these trading practices. In accordance with the findings of the financial expert, the Fund's Adviser made a contribution to Paid-in Capital of the Fund of $19,290 during the year ended January 31, 2005, for detrimental impact to the Fund from frequent trading activity and detrimental impact on those Funds that may have resulted from orders incorrectly accepted by Federated employees after the Funds' closing times.

General

Certain of the Officers and Trustees 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. 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 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.

7. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

On May 20, 2005, the Fund's Trustees, upon the recommendation of the Audit Committee, appointed Ernst & Young LLP (E&Y) as the Fund's independent registered public accounting firm. The Fund's previous independent registered public accounting firm, Deloitte & Touche LLP (D&T) declined to stand for re-election. The previous reports issued by D&T on the Fund's financial statements for the fiscal years ended January 31, 2004 and January 31, 2005, contained no adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Fund's fiscal years ended January 31, 2004 and January 31, 2005: (i) there were no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of D&T, would have caused it to make reference to the subject matter of the disagreements in connection with its reports on the financial statements for such years; and (ii) there were no reportable events of the kind described in Item 304(a) (1) (v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.

As indicated above, the Fund has appointed E&Y as the independent registered public accounting firm to audit the Fund's financial statements for the fiscal year ending January 31, 2006. During the Fund's fiscal years ended January 31, 2004 and January 31, 2005 and the interim period commencing February 1, 2005 and ending May 20, 2005, neither the Fund nor anyone on its behalf has consulted E&Y on items which: (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Fund's financial statements or (ii) concerned the subject of a disagreement (as defined in paragraph (a) (1) (iv) of Item 304 of Regulation S-K) or reportable events (as described in paragraph (a) (1) (v) of said Item 304).

Report of Independent Registered Public Accounting Firm

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FEDERATED GNMA TRUST:

We have audited the accompanying statement of assets and liabilities of Federated GNMA Trust (the "Fund"), including the portfolio of investments, as of January 31, 2006, and the related statements of operations, changes in net assets, cash flows, and financial highlights for the year 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 audit. The statement of changes in net assets for the year ended January 31, 2005 and the financial highlights for each of the four years in the period then ended were audited by another independent registered public accounting firm whose report, dated March 21, 2005, expressed an unqualified opinion on that statement and those financial highlights.

We conducted our audit 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 audit 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 January 31, 2006, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides 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 GNMA Trust at January 31, 2006, the results of its operations, changes in its net assets, cash flows, and financial highlights for the year then ended, in conformity with U.S. generally accepted accounting principles.

Board Review of Advisory Contract

As required by the 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 [these contracts], 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 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 charge.

In its decision to appoint or renew the 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 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 (if any); 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. For the past year, the Board concluded that the nature, quality and scope of services provided the fund by the Adviser and its affiliates was satisfactory.

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 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 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. For the periods ending December 31, 2004, 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. During the year ending December 31, 2004, the Fund's investment advisory fee after waivers and expense reimbursements, if any, was below the median of the relevant peer group.

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 costs incurred and 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. In addition, the availability of the exchange privilege among funds in the Federated family makes consideration of the overall cost and profitability of Federated more relevant than that of individual funds. Based upon this review, the Board is satisfied that the costs incurred in, as well as the profitability realized from, managing the Fund and the other Federated Funds are appropriate. Although the Board is always interested in discovering 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.

(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.

(e)(2)      Percentage of services identified in items 4(b) through 4(d) that
were approved by the registrants audit committee pursuant to paragraph
(c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

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

            4(c)

            services 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%

            Fiscal year ended 2005 - 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 committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01
            of 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 2006 - $71,994

            Fiscal year ended 2005 - $297,886

(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.
