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. The Fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes 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 brokers and are based on an evaluation of the inputs described. Level 3 includes significant unobservable inputs when market prices are not readily available or reliable, including the Fund’s own assumptions in determining the fair value of investments. 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 values by input classification of the Fund’s investments as of July 31, 2010, by major security category or type:

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value:

During the nine month period ended July 31, 2010, there were no significant transfers in or out of Level 1 or Level 2 assets.

In order to value the securities, the Fund uses the following valuation techniques. Equity securities held by the Fund are valued at the last sale price or official closing price on the principal securities exchange on which they trade. In the event there were no sales during the day or closing prices are not available, then securities are valued using the last quoted bid or evaluated price. 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, taking 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. Certain 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. Certain short-term securities are valued at amortized cost.

Other portfolio securities and assets, where market quotations are not readily available, are valued at fair value, as determined in good faith by the Fund’s Pricing Committee, following procedures established 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. Significant market events that affect the values of non-U.S. securities may occur after the time when the valuation of the securities is generally determined and the close of the NYSE. During significant market events, these securities will be valued at fair value, as determined in good faith, following procedures established by the Board of Trustees. The Fund may use a fair valuation model to value non-U.S. securities in order to adjust for events which may occur between the close of foreign exchanges and the close of the NYSE.

Term loans (Floating rate loans). Term loans are generally subject to legal or contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult and buying and selling a floating rate loan at an acceptable price can be more difficult and delayed, which could result in a loss.

A Fund’s ability to receive payments of principal, interest and other amounts in connection with term loans will depend primarily on the financial condition of the borrower. A Fund’s failure to receive scheduled payments on a term loan due to a default, bankruptcy or other reason, would adversely affect the Fund’s income and would likely reduce the value of its assets. Because many term loans are not rated by independent credit rating agencies, a decision to invest in a particular loan could depend exclusively on the subadviser’s credit analysis of the borrower and/or term loan agents. A Fund may have limited rights to enforce the terms of an underlying loan.

Stripped securities. Stripped mortgage backed securities are financial instruments that derive their value from other instruments so that one class receives the entire principal from the underlying mortgage assets (PO or principal only), while the other class receives the interest cash flows (IO or interest only). Both PO and IO investments represent an interest in the cash flows of an underlying stripped mortgage backed security. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully receive its initial investment in an IO security. The market value of these securities can be extremely volatile in response to changes in interest rates. In addition, these securities present additional credit risk such that the Fund may not receive all or part of its principal because the counterparty or issuer has defaulted on its obligation.

Futures. A futures contract is a contractual agreement to buy or sell a particular commodity, currency, or financial instrument at a pre-determined price in the future. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values and/or interest rates and potential losses in excess of the Fund’s initial investment.

During the nine months ended July 31, 2010, the Fund used futures contracts to manage duration of the portfolio. The following table summarizes the contracts held at July 31, 2010. The range of futures contracts notional amounts held by the Fund during the nine months ended July 31, 2010 was $2.7 to $7.4 million.

Interest rate swaps. Interest rate swaps represent an agreement between a Fund and counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. 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 interest receivable or payable under the swap contracts on a periodic basis.

During the nine months ended July 31, 2010, the Fund used interest rate swaps in anticipation of rising interest rates. The following table summarizes the interest rate swap contracts held as of July 31, 2010, which are generally representative of the interest rate swap activity. During the nine months ended July 31, 2010, the Fund invested in interest rate swaps with total notional amount as represented below.
