RDU – Restricted Depositary Unit

(a) Non-income producing security.

(b) All or portion of security is on loan. The aggregate market value of such securities is $192,338,778; cash collateral of $199,723,328 (included in liabilities) was received with which the Portfolio purchased highly liquid short-term investments.

(c) Represents security, or a portion thereof, purchased with cash collateral received for securities on loan.

(d) Prudential Investment LLC, the manager of the Fund, also serves as the manager of the Dryden Core Investment Fund-Taxable Money Market Series.

Notes to Schedule of Investments (Unaudited)

Securities Valuation: Securities listed on a securities exchange (other than options on securities and indices) are valued at the last sale price on such exchange on the day of valuation or, if there was no sale on such day, at the mean between the last reported bid and asked prices, or at the last bid price on such day in the absence if an asked price. Securities traded via Nasdaq are valued at the Nasdaq official closing price (NOCP) on the day of valuation, or if there was no NOCP, at the last sale price. Securities that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed by Prudential Investments LLC (“PI or Manager”), in consultation with the subadvisers; to be over-the-counter, are valued at market value using prices provided by an independent pricing agent or principal market maker.

Securities for which market quotations are not readily available, or whose values have been effected by events occurring after the close of the security’s foreign market and before the fund’s normal pricing time, are valued at fair value in accordance with the Board of Directors’ approved fair valuation procedures.

When determining the fair valuation of securities some of the factors influencing the valuation include, the nature of any restrictions on disposition of the securities; assessment of the general liquidity of the securities; the issuer’s financial condition and the markets in which it does business; the cost of the investment; the size of the holding and the capitalization of issuer; the prices of any recent transactions or bids/offers for such securities or any comparable securities; any available analyst media or other reports or information deemed reliable by the investment adviser regarding the issuer or the markets or industry in which it operates. Using fair value to price securities may result in a value that is different from a security’s most recent closing price and from the price used by other mutual funds to calculate their net asset values.

Market value of investments traded in a foreign currency are translated into U.S. dollars at the current rates of exchange.

Investments in mutual funds are valued at the net asset value as of the close of the New York Stock Exchange on the date of valuation.

Short-term securities which mature in sixty days or less, are valued 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 the difference between the principal amount due at maturity and cost. Short-term securities which mature in more than sixty dates are valued at current market quotations.

The Fund invests in the Taxable Money Market Series (the “Series”), a portfolio of Dryden Core Investment Fund, pursuant to an exemptive order received from the Securities and Exchange Commission. The Series is a money market mutual fund registered under the Investment Company Act of 1940, as amended, and managed by P1.

Other information regarding the Fund is available in the Fund’s most recent Report to Shareholders. This information is available on the Securities and Exchange Commission’s website (www.sec.gov).
