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. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendor or broker to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in accordance with procedures adopted by the Board. Factors used in determining fair value vary by security type and 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 Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations. 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 third party pricing vendors or from brokers who make markets in such securities. For corporate bonds and U.S. government and government agency obligations, pricing vendors utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type as well as broker-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 vendors 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 broker-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 methodologies which consider similar factors that would be used by third party pricing vendors. 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.
