Notes to the Schedule of Investments (Unaudited)

Security valuation
Investments are stated at value as of the close of the 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 an independent pricing service, which utilizes both dealer-supplied 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 as well as broker quotes. 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 broker quotes or fair valued as described below. Certain short-term debt instruments are valued at amortized cost.

Other portfolio securities and assets for which market quotations are not 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.

Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic and market conditions, interest rates, investor perceptions and market liquidity.

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. In addition, investment companies, including mutual funds, are valued using this technique.

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, foreign forward currency contracts, and certain options use these techniques.

17 



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 Funds’ investments as of July 31, 2009, by major security category or security type.

The Fund has adopted the provisions of Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (FAS 161). This new standard requires the Fund to disclose information to assist investors in understanding how the Fund uses derivative instruments, how derivative instruments are accounted for under Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (FAS 133) and how derivative instruments affect the Fund’s financial position, results of operations and cash flows. This disclosure for the period ended July 31, 2009 is presented in accordance with FAS 161 and is included as part of the Notes to the Financial Statements.

Swap contracts
The Fund may enter interest rate, credit default, cross-currency, and other forms of swaps to manage its exposure to credit, currency and interest rate risks, to gain exposure in lieu of buying in the physical market, or to enhance income. Swaps are privately negotiated agreements between counterparties to exchange cash flows, assets, foreign currencies or market-linked returns at specified intervals. In connection with these agreements, the Fund will hold cash and/or liquid securities equal to the net amount of the Fund’s exposure, in order to satisfy the Fund’s obligations in the event of default or bankruptcy/insolvency.

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 swap contracts, please refer to the Fund’s Prospectus, semi-annual and annual reports.

During the year the Fund held interest rate swaps to hedge against anticipated interest rate changes. The Fund had the following interest rate swap contracts open on July 31, 2009:

  FIXED  VARIABLE       
  PAYMENTS  PAYMENTS       
NOTIONAL  MADE BY  RECEIVED BY  TERMINATION    UNREALIZED 
AMOUNT  FUND  FUND  DATE  COUNTERPARTY  DEPRECIATION 
$28,000,000  4.6875%  3-month LIBOR  Sep 2010  Bank of America  ($698,768) 

Notional amounts of interest rate swaps at July 31, 2009 are representative of the interest rate swap activity during the period ended July 31, 2009.

Derivatives and counterparty risk
The use of derivative instruments may involve risks different from, or potentially greater than, the risks associated with investing directly in securities. Specifically, derivative instruments expose a fund to the risk that the counterparty to an over-the-counter (OTC) derivatives contract will be unable or unwilling to make timely settlement payments or otherwise to honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction. If the counterparty defaults, the Fund will have contractual remedies, but there is no assurance that the counterparty will meet its contractual obligations or that, in the event of default, the Fund will succeed in enforcing them.

Fixed income risk
Fixed income securities are subject to credit and interest rate risk and involve some risk of default in connection with principal and interest payments.

Leverage utilization risk
The Fund utilizes leverage to increase assets available for investment. The Fund has a Committed Facility Agreement (CFA) with a third party commercial bank that allows it to borrow up to $58 million and to invest the borrowings in accordance with its investment practices. Borrowings under the CFA are secured by the assets of the Fund.

Mortgage security risk
The Fund may invest a portion of its assets in issuers and/or securities of issuers that hold mortgage securities, including subprime mortgage securities. The value of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates. Decreases in interest rates may cause prepayments on underlying mortgages to an IO security to accelerate resulting in a lower than anticipated yield and increases the risk of loss on the IO investment.
