T. ROWE PRICE NEW HORIZONS FUND - -------------------------------------------------------------------------------- Certified Financials (Unaudited) June 30, 2003 NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price New Horizons Fund, Inc. (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 June 3, 1960. The fund seeks long-term capital growth by investing primarily in common stocks of small, rapidly growing companies. 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 Investments are valued 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 official closing price for certain markets, at the time the valuations are made. 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 ask prices for domestic securities and the last quoted sale price for international securities. Investments in mutual funds are valued at the closing net asset value per share of the mutual fund on the day of valuation. 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 or under the supervision of the officers of the fund, as authorized by the Board of Directors. Most foreign markets close before the NYSE. Developments that could affect the values of securities that occur between the close of a foreign market and the close of the NYSE normally will not be reflected in security valuations. However, if such developments are so significant that they will, in the judgment of the officers of the fund, clearly and materially affect the value of securities, the previous closing prices may be adjusted to reflect the fair value of the securities as of the close of the NYSE, as determined in good faith by or under the supervision of the officers of the fund, as authorized by the Board of Directors. 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 ask 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 such gains and losses. Expenses Paid Indirectly Certain security trades are directed to brokers who have agreed to rebate a portion of the related commission to the fund to pay fund expenses. Additionally, credits earned on temporarily uninvested cash balances at the custodian are used to reduce the fund's custody charges. Total expenses in the accompanying statement of operations are presented before reduction for rebates and credits, which totaled $64,000 and $2,000, respectively, for the six months ended June 30, 2003. 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. Dividend income and distributions to shareholders are recorded by the fund on the ex-dividend date. 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. 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 June 30, 2003, the value of affiliated companies totaled $315,709,000, representing 7.8% of the value of the fund's investments in securities. For the six months then ended, $5,339,000 (8.9%) of net realized loss reflected in the accompanying financial statements resulted from transactions with affiliated companies. Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $427,385,000 and $551,722,000, respectively, for the six months ended June 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 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. Temporary differences are not adjusted. 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, 2003. For tax purposes, the fund has elected to treat net capital losses realized between November 1 and December 31 of each year as occurring on the first day of the following tax year; consequently, $3,528,000 of realized losses recognized for financial reporting purposes in the year ended December 31, 2002 were recognized for tax purposes on January 1, 2003. Further, the fund intends to retain realized gains to the extent of available capital loss carryforwards. As of December 31, 2002, the fund had $367,356,000 of unused capital loss carryforwards, of which $153,213,000 expire in 2009, and $214,143,000 expire in 2010. At June 30, 2003, the cost of investments for federal income tax purposes was $3,306,522,000. Net unrealized gain aggregated $751,855,000 at period-end, of which $1,398,976,000 related to appreciated investments and $647,121,000 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 0.35% 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 net assets to those of the group. At June 30, 2003, the effective annual group fee rate was 0.32%, and investment management fee payable totaled $2,218,000. 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 $3,247,000 for the six months ended June 30, 2003, of which $579,000 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 special servicing agreements, 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 these agreements are reflected as shareholder servicing expense in the accompanying financial statements. For the six months ended June 30, 2003, the fund was allocated $458,000 of Spectrum Funds' expenses, of which $332,000 related to services provided by Price and $22,000 was payable at period-end. At June 30, 2003, approximately 9.6% 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 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. Distributions from the Reserve Funds to the fund for the six months ended June 30, 2003, totaled $385,000. Item 2. Code of Ethics.
