The Fund consists of six series--the Taxable Money Market Series (the 'Series'), the Short-Term Bond Series, the Short-Term Municipal Bond Series, the National Municipal Money Market Series, the Government Money Market Series and the Treasury Money Market Series. The Short-Term Bond Series, the Short-Term Municipal Bond Series, the National Municipal Money Market Series, the Government Money Market Series and the Treasury Money Market Series have not yet commenced operations. The investment objective of the Series is current income consistent with the preservation of capital and the maintenance of liquidity. The Series invests primarily in money market instruments maturing in 13 months or less whose ratings are within the two highest short-term ratings categories by a nationally recognized statistical rating organization or, if not rated, are of comparable quality as determined by the Series' investment advisors. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic developments in a specific industry or region. Shares of the Series are available only to investment companies managed by Prudential Investments LLC ('PI') and certain investment advisory clients of the subadvisor. At July 31, 2003, 100% of the shares outstanding were owned by such entities. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund and the Series in the preparation of its financial statements. Securities Valuation: The Series values portfolio securities at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of any discount or premium. If the amortized cost method is determined not to represent fair value, the value shall be determined by or under the direction of the Board of Trustees. The Fund may hold up to 10% of its net assets in illiquid securities, including those which are restricted as to disposition under securities law ('restricted securities'). The restricted security held by the Fund at July 31, 2003 includes registration rights under which the Fund may demand registration by the issuer. Restricted securities, Dryden Core Investment Fund - Taxable Money Market Series 13 <Page> sometimes referred to as private placements, are valued pursuant to the valuation procedures noted above. Repurchase Agreements: In connection with transactions in repurchase agreements with U.S. financial institutions, it is the Fund's policy that its custodian or designated subcustodians, as the case may be under triparty repurchase agreements, takes possession of the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase agreement exceeds one business day, the value of the collateral is marked-to-market on a daily basis to ensure the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. Securities Transactions and Net Investment Income: Securities transactions are recorded on the trade date. Realized gains (losses) on sales of securities are calculated on the identified cost basis. The Fund amortizes premiums and accretes discounts on purchases of portfolio securities as adjustments to interest income. Interest income is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require the use of certain estimates by management. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net income and capital gains, if any, to its shareholders. Therefore, no federal income tax provision is required. Dividends and Distributions: The Series declares all of its net investment income and net realized short-term capital gains or losses, if any, as dividends daily to its shareholders of record at the time of such declaration. Payment of dividends is made monthly. The Series does not expect to realize long-term capital gains or losses. Income distributions and capital gain distributions are determined in accordance with income to regulations which may differ from generally accepted accounting principles. NOTE 2. AGREEMENTS The Fund has a management agreement with PI. Pursuant to this agreement, PI has responsibility for all investment advisory services and supervises the subadvisor's performance of such services. PI has entered into a subadvisory agreement with Prudential Investment Management, Inc. ('PIM' or 'Subadvisor'). The subadvisory agreement provides that the subadvisor will furnish investment advisory services in 14 Visit our website at www.jennisondryden.com <Page> connection with the management of the Fund. In connection therewith, the subadvisor is obligated to keep certain books and records of the Fund. PI pays for the services of PIM, the cost of compensation of officers of the Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears all other costs and expenses. For its services, PI will be reimbursed for its direct costs, exclusive of any profit or overhead. The costs are accrued daily and paid monthly. For the six months ended July 31, 2003, the costs were at an annual rate of .024% of the Series' average daily net assets. PI and PIM are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). NOTE 3. OTHER TRANSACTIONS WITH AFFILIATES Prudential Mutual Fund Services LLC ('PMFS'), an affiliate of PI and an indirect wholly-owned subsidiary of Prudential, serves as the Series' transfer agent. During the six months ended July 31, 2003, the Series incurred fees of approximately $50,000 for the services of PMFS. As of July 31, 2003, $8,300 of such fees were due to PMFS. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates.
