T. Rowe Price Growth Stock Fund - -------------------------------------------------------------------------------- Certified Semiannual Report (Unaudited) June 30, 2004 Notes to Financial Statements NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Growth Stock Fund, Inc. (the fund) is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end management investment company. The fund seeks to provide long-term capital growth and, secondarily, increasing dividend income through investments in the common stocks of well-established growth companies. The fund has three classes of shares: the Growth Stock Fund original share class, referred to in this report as the Investor Class, offered since April 11, 1950, Growth Stock Fund--Advisor Class (Advisor Class), offered since December 31, 2001, and Growth Stock Fund--R Class (R Class), offered since September 30, 2002. Advisor Class shares are sold only through brokers and other financial intermediaries, and R Class shares are available to retirement plans serviced by intermediaries. The Advisor Class and R Class each operate under separate Board-approved Rule 12b-1 plans, pursuant to which each class compensates financial intermediaries for distribution, shareholder servicing, and/or certain administrative services. Each class has exclusive voting rights on matters related solely to that class, separate voting rights on matters that relate to all classes, and, in all other respects, the same rights and obligations as the other classes. 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. Equity securities listed or regularly traded on a securities exchange or in the over-the-counter market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made, except for OTC Bulletin Board securities, which are valued at the mean of the latest bid and asked prices. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the latest bid and asked prices for domestic securities and the last quoted sale price for international securities. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Purchased and written options are valued at the mean of the closing bid and asked 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 Directors. Most foreign markets close before the close of trading on the NYSE. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, in its judgment, materially affect the value of some or all of its portfolio securities, which in turn will affect the fund's share price, the fund will adjust the previous closing prices to reflect the fair value of the securities as of the close of the NYSE, as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund's Board of Directors. A fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. In deciding whether to make fair value adjustments, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U. S. markets that represent foreign securities and baskets of foreign securities. The fund uses outside pricing services to provide it with closing market prices and information used for adjusting those prices. The fund cannot predict how often it will use closing prices and how often it will adjust those prices. As a means of evaluating its fair value process, the fund routinely compares closing market prices, the next day's opening prices in the same markets, and adjusted prices. Currency Translation Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollar values each day at the prevailing exchange rate, using the mean of the bid and asked prices of such currencies against U.S. dollars as quoted by a major bank. Purchases and sales of securities, income, and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is reflected as a component of security gains and losses. Class Accounting The Advisor Class and R Class each pay distribution, shareholder servicing, and/or certain administrative expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25% and 0.50%, respectively, of the class's average daily net assets. Shareholder servicing, prospectus, and shareholder report expenses incurred by each class are charged directly to the class to which they relate. Expenses common to all classes, investment income, and realized and unrealized gains and losses are allocated to the classes based upon the relative daily net assets of each class. Rebates and Credits Subject to best execution, the fund may direct certain security trades to brokers who have agreed to rebate a portion of the related brokerage commission to the fund in cash. Commission rebates are included in realized gain on securities in the accompanying financial statements and totaled $179,000 for the six months ended June 30, 2004. Additionally, the fund earns credits on temporarily uninvested cash balances at the custodian that reduce the fund's custody charges. Custody expense in the accompanying financial statements is presented before reduction for credits. Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared and paid by each class on an annual basis. Capital gain distributions, if any, are declared and paid by the fund, typically on an annual basis. Other 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. Options Call and put options give the holder the right to purchase or sell, respectively, a security at a specified price on a certain date. Risks arise from possible illiquidity of the options market and from movements in security values. Options are reflected in the accompanying Portfolio of Investments at market value. Transactions in options written and related premiums received during the six months ended June 30, 2004, were as follows: - -------------------------------------------------------------------------------- Number of Contracts Premiums Outstanding at beginning of period - $ - Written 9,400 2,115,000 Exercised (1,000) (194,000) Closed (5,500) (1,455,000) Outstanding at end of period 2,900 $ 466,000 -------------------------- Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $1,951,914,000 and $991,310,000, respectively, for the six months ended June 30, 2004. 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 June 30, 2004. The fund intends to retain realized gains to the extent of available capital loss carryforwards. As of December 31, 2003, the fund had $600,453,000 of unused capital loss carryforwards, of which $352,727,000 expire in 2009, $236,038,000 expire in 2010, and $11,688,000 expire in 2011. At June 30, 2004, the cost of investments for federal income tax purposes was $5,309,190,000. Net unrealized gain aggregated $1,542,411,000 at period-end, of which $1,606,424,000 related to appreciated investments and $64,013,000 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 0.25% 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 June 30, 2004, the effective annual group fee rate was 0.31%, and investment management fee payable totaled $3,098,000. The Advisor Class and R Class are also subject to a contractual expense limitation through the limitation dates indicated in the table below. During the limitation period, the manager is required to waive its management fee and reimburse a class for any expenses, excluding interest, taxes, brokerage commissions, and extraordinary expenses, that would otherwise cause the class's ratio of total expenses to average net assets (expense ratio) to exceed its expense limitation. Through the repayment date, each class is required to repay the manager for expenses previously reimbursed and management fees waived to the extent the class's net assets have grown or expenses have declined sufficiently to allow repayment without causing the class's expense ratio to exceed its expense limitation. - -------------------------------------------------------------------------------- Advisor Class R Class Expense Limitation 1.10% 1.35% Limitation Date 4/30/06 4/30/06 Repayment Date 4/30/08 4/30/08 For the six months ended June 30, 2004, each class operated below its expense limitation. 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 prices 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 Investor Class and R Class. Expenses incurred pursuant to these service agreements totaled $3,296,000 for the six months ended June 30, 2004, of which $546,000 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) and T. Rowe Price Retirement Funds (Retirement Funds) may invest. Neither the Spectrum Funds nor the Retirement Funds invest in the underlying Price funds for the purpose of exercising management or control. Pursuant to separate, special servicing agreements, expenses associated with the operation of the Spectrum and Retirement 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 and Retirement Funds, respectively. Expenses allocated under these agreements are reflected as shareholder servicing expenses in the accompanying financial statements. For the six months ended June 30, 2004, the fund was allocated $287,000 of Spectrum Funds' expenses and $399,000 of Retirement Funds' expenses. Of these amounts, $476,000 related to services provided by Price and $123,000 was payable at period-end. At June 30, 2004, approximately 4.9% of the outstanding shares of the Investor Class were held by the Spectrum Funds and 3.9% were held by the Retirement 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 to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates, and are not available for direct purchase by members of the public. The Reserve Funds pay no investment management fees. During the six months ended June 30, 2004, dividend income from the Reserve Funds totaled $856,000. T.
