2 Securities with a value of $1,583,000 have been segregated as initial margin for open futures contracts.
REIT - Real Estate Investment Trust.

Investment Securities: 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 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 June 30, 2007, the cost of investment securities for tax purposes was $6,877,337,000. Net unrealized appreciation of investment securities for tax purposes was $1,186,935,000, consisting of unrealized gains of $1,292,309,000 on securities that had risen in value since their purchase and $105,374,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: The fund invests a portion of its cash reserves in equity markets through the use of index futures contracts. After giving effect to futures investments, the fund's effective common stock and temporary cash investment positions represent 100.0% and 0.1%, respectively, of net assets. Futures contracts are valued at their quoted daily settlement prices.

At June 30, 2007, the aggregate settlement value of open futures contracts expiring in September 2007 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
S&P 500 Index	110	41,674	212

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

* Non-income-producing security.

1 The issuer operates under a congressional charter; its securities are neither issued nor guaranteed by the U.S. government. If needed, access to additional funding from the U.S. Treasury (beyond the issuer's line of credit) would require congressional action.

2 Securities with a value of $100,000 have been segregated as initial margin for open futures contracts.
REIT - Real Estate Investment Trust.

Investment Securities: 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 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 June 30, 2007, the cost of investment securities for tax purposes was $711,395,000. Net unrealized appreciation of investment securities for tax purposes was $83,507,000, consisting of unrealized gains of $91,330,000 on securities that had risen in value since their purchase and $7,823,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: The fund invests a portion of its cash reserves in equity markets through the use of index futures contracts. After giving effect to futures investments, the fund's effective common stock and temporary cash investment positions represent 100.2% and -0.2%, respectively, of net assets. Futures contracts are valued at their quoted daily settlement prices.

At June 30, 2007, the aggregate settlement value of open futures contracts expiring in September 2007 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
E-mini S&P 500 Index	29	2,197	10

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

* Non-income-producing security.

1 Affiliated money market fund available only to Vanguard funds and certain trusts and accounts managed by Vanguard. Rate shown is the 7-day yield.

2 The issuer operates under a congressional charter; its securities are neither issued nor guaranteed by the U.S. government. If needed, access to additional funding from the U.S. Treasury (beyond the issuer's line of credit) would require congressional action.

3 Securities with a value of $100,000 have been segregated as initial margin for open futures contracts. REIT - Real Estate Investment Trust.

Investment Securities: 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 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 June 30, 2007, the cost of investment securities for tax purposes was $107,793,000. Net unrealized appreciation of investment securities for tax purposes was $18,499,000, consisting of unrealized gains of $20,021,000 on securities that had risen in value since their purchase and $1,522,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: The fund invests a portion of its cash reserves in equity markets through the use of index futures contracts. After giving effect to futures investments, the fund's effective common stock and temporary cash investment positions represent 100.0% and 4.1%, respectively, of net assets. Futures contracts are valued at their quoted daily settlement prices.

At June 30, 2007, the aggregate settlement value of open futures contracts expiring in September 2007 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
S&P 500 Index	1	379	2
E-mini S&P 500 Index	2	151	(2)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.

3 Securities with a value of $100,000 have been segregated as initial margin for open futures contracts.
REIT - Real Estate Investment Trust.

Investment Securities: 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 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 June 30, 2007, the cost of investment securities for tax purposes was $58,515,000. Net unrealized appreciation of investment securities for tax purposes was $6,681,000, consisting of unrealized gains of $7,513,000 on securities that had risen in value since their purchase and $832,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: The fund invests a portion of its cash reserves in equity markets through the use of index futures contracts. After giving effect to futures investments, the fund's effective common stock and temporary cash investment positions represent 100.3% and -0.3%, respectively, of net assets. Futures contracts are valued at their quoted daily settlement prices.

At June 30, 2007, the aggregate settlement value of open futures contracts expiring in September 2007 and the related unrealized appreciation (depreciation) were:

		($000)
Futures Contracts	Number of Long Contracts	Aggregate Settlement Value	Unrealized Appreciation (Depreciation)
E-mini S&P 500 Index	6	455	(4)

Unrealized appreciation (depreciation) on open futures contracts is required to be treated as realized gain (loss) for tax purposes.
