T. Rowe Price GNMA Fund - -------------------------------------------------------------------------------- Certified Semiannual Report (Unaudited) November 30, 2003 Notes To Financial Statements - -------------------------------------------------------------------------------- NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price GNMA Fund (the fund) is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end management investment company and commenced operations on November 26, 1985. The fund seeks high current income consistent with maximum credit protection and moderate price fluctuation by investing exclusively in securities backed by the full faith and credit of the U.S. government and instruments linked to these securities. The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of estimates made by fund management. Valuation The fund values its investments and computes its net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business. Debt securities are generally traded in the over-the-counter market. Securities with original maturities of one year or more are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Securities with original maturities of less than one year are stated at fair value, which is determined by using a matrix system that establishes a value for each security based on bid-side money market yields. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Financial futures contracts are valued at closing settlement prices. Other investments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund's Board of Trustees. Expenses Paid Indirectly Credits earned on temporarily uninvested cash balances at the custodian are used to reduce the fund's custody charges. Other Income and expenses are recorded on the accrual basis. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Distributions to shareholders are recorded by the fund on the ex-dividend date. Dividends from mutual fund investments are reflected as dividend income; capital gain distributions from mutual fund investments are reflected as realized gain/loss. Payments ("variation margin") made or received by the fund to settle the daily fluctuations in the value of futures contracts are recorded as unrealized gains or losses until the contracts are closed. Unrealized gains and losses on futures contracts are included in Other assets and other liabilities respectively, and in Change in net unrealized gain or loss in the accompanying financial statements. In the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is dependent on claims that may be made against the fund in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote. NOTE 2 - INVESTMENT TRANSACTIONS Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks or enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund's prospectus and Statement of Additional Information. Futures Contracts During the six months ended November 30, 2003, the fund was a party to futures contracts, which provide for the future sale by one party and purchase by another of a specified amount of a specific financial instrument at an agreed upon price, date, time, and place. Risks arise from possible illiquidity of the futures market and from movements in security values. Repurchase Agreements All repurchase agreements are fully collateralized by U.S. government securities. Collateral is in the possession of the fund's custodian or, for tri-party agreements, the custodian designated by the agreement. Collateral is evaluated daily to ensure that its market value exceeds the delivery value of the repurchase agreements at maturity. Although risk is mitigated by the collateral, the fund could experience a delay in recovering its value and a possible loss of income or value if the counter-party fails to perform in accordance with the terms of the agreement. Affiliated Companies The fund may invest in certain securities that are considered affiliated companies. As defined by the 1940 Act, an affiliated company is one in which the fund owns 5% or more of the outstanding voting securities. At November 30, 2003, the fund's investment in the T. Rowe Price Government Reserve Investment Fund was its only affiliated holding and represented 19.5% of the value of the fund's investments in securities. Other Purchases and sales of U.S. government securities aggregated $2,116,692,000 and $2,236,430,000, respectively, for the six months ended November 30, 2003. NOTE 3 - FEDERAL INCOME TAXES No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Federal income tax regulations differ from generally accepted accounting principles; therefore, distributions determined in accordance with tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. The amount and character of tax-basis distributions and composition of net assets are finalized at fiscal year-end; accordingly, tax-basis balances have not been determined as of November 30, 2003. For tax purposes, the fund has elected to treat net capital losses realized between November 1 and May 31 of each year as occurring on the first day of the following tax year; consequently, $651,000 of realized losses recognized for financial reporting purposes in the year ended May 31, 2003 were recognized for tax purposes on June 1, 2003. At November 30, 2003, the cost of investments for federal income tax purposes was $1,662,821,000. Net unrealized gain aggregated $16,754,000 at period-end, of which $25,651,000 related to appreciated investments and $8,897,000 related to depreciated investments. NOTE 4- RELATED PARTY TRANSACTIONS The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The investment management agreement between the fund and the manager provides for an annual investment management fee, which is computed daily and paid monthly. The fee consists of an individual fund fee, equal to 0.15% of the fund's average daily net assets, and the fund's pro-rata share of a group fee. The group fee is calculated based on the combined net assets of certain mutual funds sponsored by Price Associates (the group) applied to a graduated fee schedule, with rates ranging from 0.48% for the first $1 billion of assets to 0.295% for assets in excess of $120 billion. The fund's portion of the group fee is determined by the ratio of its average daily net assets to those of the group. At November 30, 2003, the effective annual group fee rate was 0.32%, and investment management fee payable totaled $519,000. In addition, the fund has entered into service agreements with Price Associates and two wholly owned subsidiaries of Price Associates (collectively, Price). Price Associates computes the daily share price and maintains the financial records of the fund. T. Rowe Price Services, Inc., provides shareholder and administrative services in its capacity as the fund's transfer and dividend disbursing agent. T. Rowe Price Retirement Plan Services, Inc., provides subaccounting and recordkeeping services for certain retirement accounts invested in the fund. Expenses incurred pursuant to these service agreements totaled $573,000 for the six months ended November 30, 2003, of which $100,000 was payable at period-end. The fund is also one of several mutual funds sponsored by Price Associates (underlying Price funds) in which the T. Rowe Price Spectrum Funds (Spectrum Funds) may invest. The Spectrum Funds do not invest in the underlying Price funds for the purpose of exercising management or control. Pursuant to a special servicing agreement, expenses associated with the operation of the Spectrum Funds are borne by each underlying Price fund to the extent of estimated savings to it and in proportion to the average daily value of its shares owned by the Spectrum Funds. Expenses allocated under this agreement are reflected as shareholder servicing expense in the accompanying financial statements. For the six months ended November 30, 2003, the fund was allocated $478,000 of Spectrum Funds' expenses, of which $447,000 related to services provided by Price and $75,000 was payable at period-end. At November 30, 2003, approximately 31% of the outstanding shares of the fund were held by the Spectrum Funds. The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe Price Government Reserve Investment Fund (collectively, the Reserve Funds), open-end management investment companies managed by Price Associates. The Reserve Funds are offered as cash management options only to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates, and are not available to the public. The Reserve Funds pay no investment management fees. During the six months ended November 30, 2003, dividend income from the Reserve Funds totaled $1,248,000. T.
