A. Security Valuation: Securities are valued as of the close of trading on
the New York Stock Exchange (generally 4 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 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.

B. Futures Contracts: The fund uses index futures contracts to a limited
extent, with the objectives of maintaining full exposure to the stock
market, maintaining liquidity, and minimizing transaction costs. The fund
may purchase futures contracts to immediately invest incoming cash in the
market, or sell futures in response to cash outflows, thereby simulating a
fully invested position in the underlying index while maintaining a cash
balance for liquidity. The primary risks associated with the use of futures
contracts are imperfect correlation between changes in market values of
stocks held by the fund and the prices of futures contracts, and the
possibility of an illiquid market. Counterparty risk involving futures is
mitigated because a regulated clearinghouse is the counterparty instead of
the clearing broker. To further mitigate counterparty risk, the fund trades
futures contracts on an exchange, monitors the financial strength of its
clearing brokers and clearinghouse, and has entered into clearing
agreements with its clearing brokers. The clearinghouse imposes initial
margin requirements to secure the fund’s performance and requires daily
settlement of variation margin representing changes in the market value of
each contract. Any assets pledged as initial margin for open contracts are
noted in the Schedule of Investments.

Futures contracts are valued at their quoted daily settlement prices. The
notional amounts of the contracts are not recorded in the Schedule of
Investments. Fluctuations in the value of the contracts are recorded as an
asset (liability).

C. Various inputs may be used to determine the value of the fund's
investments. These inputs are summarized in three broad levels for
financial statement purposes. The inputs or methodologies used to value
securities are not necessarily an indication of the risk associated with
investing in those securities.

Level 1—Quoted prices in active markets for identical securities.
Level 2—Other significant observable inputs (including quoted prices for
similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3—Significant unobservable inputs (including the fund's own
assumptions used to determine the fair value of investments). Any
investments valued with significant unobservable inputs are noted on the
Schedule of Investments.
