Notes to Financial Statements - -------------------------------------------------------------------------------- T. Rowe Price Equity Index 500 Portfolio - -------------------------------------------------------------------------------- Certified Financials June 30, 2003 (Unaudited) NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Equity Series, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act). The Equity Index 500 Portfolio (the fund), a diversified, open-end management investment company, is one of the portfolios established by the corporation and commenced operations on December 29, 2000. The fund seeks to match the performance of the Standard & Poor's 500 Stock Index(RT). Shares of the fund are currently offered only through certain insurance companies as an investment medium for both variable annuity contracts and variable life insurance policies. 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 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. Short-term debt securities are valued at amortized cost, which approximates fair value when combined with accrued interest. Investments in mutual funds are valued at the closing net asset value per share of the mutual fund 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 or under the supervision of the officers of the fund, as authorized by the Board of Directors. Premiums and Discounts Premiums and discounts on debt securities are amortized for financial reporting purposes. 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. 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 Change in net unrealized gain or loss in the accompanying financial statements. 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 June 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. Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $817,000 and $591,000, 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. The fund intends to retain realized gains to the extent of available capital loss carryforwards. As of December 31, 2002, the fund had $209,000 of unused capital loss carryforwards, of which $26,000 expire in 2009, and $183,000 expire in 2010. At June 30, 2003, the cost of investments for federal income tax purposes was $6,217,000. Net unrealized loss aggregated $921,000 at period-end, of which $233,000 related to appreciated investments and $1,154,000 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 and administrative agreement between the fund and the manager provides for an all-inclusive annual fee equal to 0.40% of the fund's average daily net assets. The fee is computed daily and paid monthly. The agreement provides that investment management, shareholder servicing, transfer agency, accounting, and custody services are provided to the fund, and interest, taxes, brokerage commissions, directors' fees and expenses, and extraordinary expenses are paid directly by the fund.
