Investment Securities: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been materially affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the board of trustees to represent fair value. Investments in Vanguard Market Liquidity Fund are valued at that fund’s net asset value. Temporary cash investments acquired over 60 days to maturity are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services. Other temporary cash investments are valued at amortized cost, which approximates market value.

At May 31, 2005, the cost of investment securities for tax purposes was $48,977,000. Net unrealized depreciation of investment securities for tax purposes was $972,000, consisting of unrealized gains of $1,686,000 on securities that had risen in value since their purchase and $2,658,000 in unrealized losses on securities that had fallen in value since their purchase.
