Other Information

All investments are categorized as Level 1 under the Fair Value Hierarchy. The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities. For more information on valuation inputs, please refer to the Investment Valuation section at the end of this listing.

Income Tax Information

At August 31, 2010, the cost of investment securities for income tax purposes was $33,052,757. Net unrealized depreciation aggregated $2,354,069, of which $1,940,556 related to appreciated investment securities and $4,294,625 related to depreciated investment securities.

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. 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.

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts, futures contracts, Exchange-traded funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy in these circumstances. Utilizing these techniques may result in transfers between Level 1 and Level 2. For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used and are categorized as Level 3 in the hierarchy.

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day and are categorized as Level 1 in the hierarchy. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are 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.
