Mid-Cap Value Index Fund

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.
