Investment Valuation

Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. Security transactions are accounted for as of trade date. The Fund uses independent pricing services approved by the Board of Trustees to value its investments. When current market prices or quotations are not readily available or reliable, valuations may be determined in good faith in accordance with procedures adopted by the Board of Trustees. Factors used in determining value may include market or security specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The value used for net asset value calculation under these procedures may differ from published prices for the same securities. The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels: Level 1 - quoted prices in active markets for identical investments. Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds etc.). Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available). Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from independent pricing services or from dealers who make markets in such securities. For U.S. government and government agency obligations, pricing services utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices and are generally categorized as Level 2 in the hierarchy.

For collateralized mortgage obligations, commercial mortgage securities and U.S. government agency mortgage securities, pricing services utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices and, accordingly, such securities are generally categorized as Level 2 in the hierarchy. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing matrices which consider similar factors that would be used by independent pricing services. These are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Short-term securities with remaining maturities of sixty days or less may be valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

For additional information on the Fund's policy regarding valuation of investments and other significant accounting policies, please refer to the Fund's most recent semiannual or annual shareholder report.
