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.

3 Security exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be sold in transactions exempt from registration, normally to qualified institutional buyers.

GO - General Obligation Bond.

Investment Securities: Bonds, and 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. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $5,638,249,000. Net unrealized appreciation of investment securities for tax purposes was $24,707,000, consisting of unrealized gains of $187,660,000 on securities that had risen in value since their purchase and $162,953,000 in unrealized losses on securities that had fallen in value since their purchase.

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157"), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At April 30, 2008, 100% of the fund's investments were valued based on Level 2 inputs.

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 The average or expected maturity is shorter than the final maturity shown because of the possibility of interim principal payments and prepayments or the possibility of the issue being called.
3 Adjustable-rate note.
4 Security exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be sold in transactions exempt from registration, normally to qualified institutional buyers. At April 30, 2008, the aggregate value of these securities was $2,991,740,000 representing 14.7% of net assets.
5 Securities with a value of $18,382,000 have been segregated as initial margin for open futures contracts.
6 Scheduled principal and interest payments are guaranteed by Municipal Bond Insurance Association.
7 Affiliated money market fund available only to Vanguard funds and certain trusts and accounts managed by Vanguard. Rate shown is the 7-day yield. GO - General Obligation Bond. 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. Bonds, and 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. Investments in Vanguard Market Liquidity fund are valued at that fund's net asset value. Other temporary cash investments are valued at amortized cost, which approximates market value. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $20,444,031,000. Net unrealized depreciation of investment securities for tax purposes was $280,670,000, consisting of unrealized gains of $155,372,000 on securities that had risen in value since their purchase and $436,042,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: Futures contracts are valued at their quoted daily settlement prices.

At April 30, 2008, the aggregate settlement value of open futures contracts expiring in June 2008 and the related unrealized appreciation (depreciation) were:


($000)

2-Year U.S. Treasury Note 1,471  312,863  (3,682)

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

Swap Contracts: The fund has sold credit protection through credit default swaps, to simulate investments in long bond positions that are either unavailable or considered to be less attractively priced in the bond market.The fund has also purchased credit protection through credit default swaps to reduce credit exposure to a given issuer or issuers. Under the terms of the swaps,the seller of the credit protection receives a periodic payment amount (premium) from the buyer that is a fixed percentage amount applied to a notional principal amount. In return, the seller agrees to pay the buyer the notional amount and take delivery of a debt instrument of the reference issuer of the same notional par amount if the reference entity is subject to a credit event (such as bankruptcy, failure to pay, or obligation acceleration) during the term of the swap.

The fund has also entered into interest rate swap transactions. Under the terms of the swaps, one party pays the other an amount that is a fixed percentage rate applied to a notional principal amount. In return, the counterparty agrees to pay a floating rate, which is reset periodically based on short-term interest rates, applied to the same notional amount.

Swaps are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time realized gain (loss) is recorded.

At April 30, 2008, the fund had the following open swap contracts:

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table sumamrizes the inputs used to value the fund's net assets as of April 30, 2008:

1 Securities with a value of $2,547,000 have been segregated as initial margin for open futures contracts.
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 The average or expected maturity is shorter than the final maturity shown because of the possibility of interim principal payments and prepayments or the possibility of the issue being called.

Investment Securities: Bonds, and 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. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $2,949,800,000. Net unrealized appreciation of investment securities for tax purposes was $49,196,000, consisting of unrealized gains of $55,014,000 on securities that had risen in value since their purchase and $5,818,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: Futures contracts are valued at their quoted daily settlement prices.

At April 30, 2008, the aggregate settlement value of open futures contracts expiring in June 2008 and the related unrealized appreciation (depreciation) were:

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

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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.).

1 Securities with a value of $2,594,000 have been segregated as initial margin for open futures contracts.
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 The average or expected maturity is shorter than the final maturity shown because of the possibility of interim principal payments and prepayments or the possibility of the issue being called.

Investment Securities: Bonds, and 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. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $4,452,366,000. Net unrealized appreciation of investment securities for tax purposes was $46,114,000, consisting of unrealized gains of $62,371,000 on securities that had risen in value since their purchase and $16,257,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: Futures contracts are valued at their quoted daily settlement prices.

At April 30, 2008, the aggregate settlement value of open futures contracts expiring in June 2008, and the related unrealized appreciation (depreciation) were:

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

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table sumamrizes the inputs used to value the fund's net assets as of April 30, 2008:

1 Security exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be sold in transactions exempt from registration, normally to qualified institutional buyers. At April 30, 2008, the aggregate value of these securities was $764,551,000, representing 8.4% of net assets.
2 Adjustable-rate note.
3 The average or expected maturity is shorter than the final maturity shown because of the possibility of interim principal payments and prepayments or the possibility of the issue being called.
4 Affiliated money market fund available only to Vanguard funds and certain trusts and accounts managed by Vanguard. Rate shown is the 7-day yield.

Investment Securities: Bonds, and 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. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value. Other temporary cash investments are valued at amortized cost, which approximates market value. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $9,605,080,000. Net unrealized depreciation of investment securities for tax purposes was $457,900,000, consisting of unrealized gains of $122,866,000 on securities that had risen in value since their purchase and $580,766,000 in unrealized losses on securities that had fallen in value since their purchase.

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table sumamrizes the inputs used to value the fund's net assets as of April 30, 2008:

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 The average or expected maturity is shorter than the final maturity shown because of the possibility of interim principal payments and prepayments or the possibility of the issue being called.
3 Adjustable-rate security.
4 Security exempt from registration under Rule 144A of the Securities Act of 1933. Such securities may be sold in transactions exempt from registration, normally to qualified institutional buyers. At April 30, 2008, the aggregate value of these securities was $863,147,000, representing 14.0% of net assets.
5 Securities with a value of $10,666,000 have been segregated as initial margin for open futures contracts.
6 Scheduled principal and interest payments are guaranteed by Municipal Bond Insurance Association.
7 Affiliated money market fund available only to Vanguard funds and certain trusts and accounts managed by Vanguard. Rate shown is the 7-day yield.GO - General Obligation Bond.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. Bonds, and 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. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value. Other temporary cash investments are valued at amortized cost, which approximates market value. 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.

At April 30, 2008, the cost of investment securities for tax purposes was $6,218,875,000. Net unrealized depreciation of investment securities for tax purposes was $105,912,000, consisting of unrealized gains of $87,060,000 on securities that had risen in value since their purchase and $192,972,000 in unrealized losses on securities that had fallen in value since their purchase.

Futures Contracts: Futures contracts are valued at their quoted daily settlement prices.

At April 30, 2008, the aggregate settlement value of open futures contracts expiring in June 2008 and the related unrealized appreciation (depreciation) were:

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

Swap Contracts: The fund has sold credit protection through credit default swaps, to simulate investments in long bond positions that are either unavailable or considered to be less attractively priced in the bond market. Under the terms of the swaps,the seller of the credit protection receives a periodic payment amount (premium) from the buyer that is a fixed percentage amount applied to a notional principal amount. In return, the seller agrees to pay the buyer the notional amount and take delivery of a debt instrument of the reference issuer of the same notional par amount if the reference entity is subject to a credit event (such as bankruptcy, failure to pay, or obligation acceleration) during the term of the swap.

The fund has also entered into interest rate swap transactions. Under the terms of the swaps, one party pays the other an amount that is a fixed percentage rate applied to a notional principal amount. In return, the counterparty agrees to pay a floating rate, which is reset periodically based on short-term interest rates, applied to the same notional amount.

The fund has also entered into swap transactions to earn the total return on a specified security or index of fixed income securities. Under the terms of the swaps, the fund receives the total return (either receiving the increase or paying the decrease) on a reference security or index, applied to a notional principal amount. In return, the fund agrees to pay the counterparty a floating rate, which is reset periodically based on short-term interest rates, applied to the same notional amount. At the same time, the fund invests an amount equal to the notional amount of the swaps in high-quality floating-rate securities.

Swaps are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time realized gain (loss) is recorded.

At April 30, 2008, the fund had the following open swap contracts:

In September 2006, the Financial Accounting Standards Board issued Interpretation No. 157 ("FAS 157), "Fair Value Measurements." FAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements in financial statements, effective for the fund's current fiscal period.

Various inputs may be used to determine the value of the fund's investments. These inputs are summarized in three broad levels:

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).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table sumamrizes the inputs used to value the fund's net assets as of April 30, 2008:
