Note: Percentages indicated are based on the net assets of the fund.

Note 1. Portfolio Valuation: Investments in securities that are listed on the New York Stock Exchange are valued, except as indicated below, at the last sale price reflected at the close of the New York Stock Exchange on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices for the day or, if no asked price is available, at the bid price.

Securities not listed on the New York Stock Exchange but listed on other domestic or foreign securities exchanges or admitted to trading on the National Association of Securities Dealers Automated Quotations, Inc. (Nasdaq) national market system are valued in a similar manner. Securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined as reflected on the tape at the close of the exchange representing the principal market for such securities.

Readily marketable securities traded in the over-the-counter market, including listed securities whose primary market is believed by Cohen & Steers Capital Management, Inc. (the investment manager) to be over-the-counter, but excluding securities admitted to trading on the Nasdaq National List, are valued at the official closing prices as reported by Nasdaq, the National Quotation Bureau, or such other comparable sources as the Board of Directors deem appropriate to reflect their fair market value. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices for the day, or if no asked price is available, at the bid price. However, certain fixed-income securities may be valued on the basis of prices provided by a pricing service when such prices are believed by the Board of Directors to reflect the fair market value of such securities. Where securities are traded on more than one exchange and also over-the-counter, the securities will generally be valued using the quotations the Board of Directors believes most closely reflect the value of such securities.

Securities for which market prices are unavailable, or securities for which the investment manager determines that bid and/or asked price does not reflect market value, will be valued at fair value pursuant to procedures approved by the fund’s Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems appropriate. These may include recent transactions in comparable securities, information relating to the specific security and developments in the markets.

The fund’s use of fair value pricing may cause the net asset value of fund shares to differ from the net asset value that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Short-term debt securities, which have a maturity date of 60 days or less, are valued at amortized cost, which approximates value.
