Notes to Financial Statements T. Rowe Price Blue Chip Growth Portfolio Certified Semiannual Report June 30, 2004 (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 Blue Chip Growth Portfolio (the fund) is a diversified, open-end management investment company and is one portfolio established by the corporation. The fund seeks to provide long-term capital growth. Income is a secondary objective. 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 fund has two classes of shares: the Blue Chip Growth original share class (Blue Chip Growth Class), offered since December 29, 2000, and Blue Chip Growth-II (Blue Chip Growth-II Class), offered since April 30, 2002). Blue Chip Growth-II shares are sold through financial intermediaries, which it compensates for distribution, shareholder servicing, and/or certain administrative services under a Board-approved Rule 12b-1 plan. Each class has exclusive voting rights on matters related solely to that class, separate voting rights on matters that relate to both classes, and, in all other respects, the same rights and obligations as the other class. 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. 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 Blue Chip Growth-II Class pays distribution, shareholder servicing, and/or certain administrative expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25% of the class's average daily net assets. Management and administrative fee expenses, investment income, and realized and unrealized gains and losses are allocated to the classes based upon the relative daily net assets of each class. 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 Purchases and sales of portfolio securities, other than short-term securities, aggregated $19,194,000 and $3,070,000, 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 $1,278,000 of unused capital loss carryforwards, of which $452,000 expire in 2009, $491,000 expire in 2010, and $335,000 expire in 2011. At June 30, 2004, the cost of investments for federal income tax purposes was $42,578,000. Net unrealized gain aggregated $4,403,000 at period-end, of which $4,947,000 related to appreciated investments and $544,000 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 0.85% 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. At June 30, 2004, $36,000 was payable under the agreement. 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 $4,000. T.
