Notes to the Schedule of Investments (Unaudited)

Security valuation

Investments are stated at value as of the close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. Equity securities held by the Fund are valued at the last sale price or official closing price (closing bid price or last evaluated price if no sale has occurred) as of the close of business on the principal securities exchange (domestic or foreign) on which they trade. Debt obligations are valued based on the evaluated prices provided by independent pricing services, which utilizes both dealer-supplied quotes and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing service. Securities traded only in the over-the-counter market are valued at the last bid price quoted by brokers making markets in the securities at the close of trading. Equity and debt obligations, for which there are no prices available from an independent pricing service, are valued based on bid quotations, or evaluated prices, as applicable, obtained from broker-dealers or fair valued as described below. Certain short-term debt instruments are valued at amortized cost.

Other assets and securities for which no such quotations are readily available are valued at fair value as determined in good faith by the Fund’s Pricing Committee in accordance with procedures adopted by the Board of Trustees. Generally, trading in non-U.S. securities is substantially completed each day at various times prior to the close of trading on the NYSE. The values of such securities used in computing the net asset value of the Fund’s shares are generally determined as of such times. Occasionally, significant events that affect the values of such securities may occur between the times at which such values are generally determined and the close of the NYSE. Upon such an occurrence, these securities will be valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

Fair value measurements

The Fund uses a three-tier hierarchy to prioritize the assumptions, referred to as inputs, used in valuation techniques to measure fair value. The three-tier hierarchy of inputs and the valuation techniques used are summarized below:

Level 1 — Exchange traded prices in active markets for identical securities. This technique is used for exchange-traded domestic common and preferred equities, certain foreign equities, warrants, rights, options and futures.

Level 2 — Prices determined using significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these techniques are received from independent pricing vendors and are based on an evaluation of the inputs described. These techniques are used for certain domestic preferred equities, certain foreign equities, unlisted rights and warrants, and fixed income securities. Also, over-the-counter derivative contracts, including swaps use these techniques.

Level 3 — Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable, such as when there is little or no market activity for an investment, unobservable inputs may be used. Unobservable inputs reflect the Fund’s Pricing Committee’s own assumptions about the factors that market participants would use in pricing an investment and would be based on the best information available. Securities using this technique are generally thinly traded or privately placed, and may be valued using broker quotes, which may not only use observable or unobservable inputs but may also include the use of the brokers’ own judgments about the assumptions that market participants would use.



The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used to value the Fund’s investments as of October 31, 2009, by major security category or security type. Other financial instruments are derivative instruments not reflected in the Portfolio of Investments, such as interest rate swap contracts, which are stated at market value.

Repurchase agreements

The Fund may enter into repurchase agreements. When the Fund enters into a repurchase agreement through its custodian, it receives delivery of securities, the amount of which, at the time of purchase and each subsequent business day, is required to be maintained at such a level that the market value is generally at least 102% of the repurchase amount. The Fund will take receipt of all securities underlying the repurchase agreements it has entered into, until such agreements expire. If the seller defaults, the Fund would suffer a loss to the extent that proceeds from the sale of underlying securities were less than the repurchase amount. The Fund may enter into repurchase agreements maturing within seven days with domestic dealers, banks or other financial institutions deemed to be creditworthy by the Adviser.

Interest rate swap agreements

Interest rate swaps represent an agreement between two counterparties to exchange cash flows based on the difference in the two interest rates, applied to the notional principal amount for a specified period. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The Fund settles accrued net receivable or payable under the swap contracts on a periodic basis. For more information on interest rate swap contracts, please refer to the Fund’s Prospectus, semi-annual and annual reports.



The Fund entered into interest rate swaps in anticipation of rising interest rates. The following summarizes the contracts held at October 31, 2009:
