An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1 per share, it is possible to lose money by investing in the fund. All of Vanguard’s money market funds have agreed to participate in the U.S. Treasury’s Temporary Guarantee Program for Money Market Funds. The program provides a guarantee to participating money market mutual fund shareholders based on the number of shares invested in the fund at the close of business on September 19, 2008. Any increase in the number of shares an investor holds after the close of business on September 19, 2008, will not be guaranteed. If a customer closes his or her account with a fund or broker-dealer, any future investment in the fund will not be guaranteed. If the number of shares an investor holds fluctuates over the period, the investor will be covered for either the number of shares held as of the close of business on September 19, 2008, or the current amount, whichever is less. The program expires on April 30, 2009, unless extended by the U.S. Treasury.

1 7-day SEC yield for the Tax-Exempt Money Market Fund; 30-day SEC yield for the other funds.

2 This calculation, which assumes a typical itemized tax return, is based on the maximum federal income tax rate of 35%. State and local taxes were not considered. Please see the prospectus for a detailed explanation of the calculation.

Municipal securities experienced unusual volatility during the past 12 months as the global credit crunch reverberated through this typically sedate segment of the fixed income markets.

The seven Vanguard Municipal Bond Funds posted returns for the period ranging from a high of 3.76% for the Admiral Shares of the Short-Term Tax-Exempt Fund to a low of –8.20% for the Investor Shares of the High-Yield Tax-Exempt Fund. In these unsettled markets, the funds fared better than their typical peers, a tribute to the funds’ advisor—Vanguard Fixed Income Group—and its customary emphasis on high-quality, liquid securities.

With the exception of the Tax-Exempt Money Market and Short-Term Tax-Exempt Funds, the Municipal Bond Funds’ yields rose over the 12 months ended October 31, 2008. In the case of the High-Yield Fund, for example, the 30-day SEC yield of the Admiral Shares at the fiscal year-end was 5.54%, up from 4.42% at the start. Taxable-equivalent yields for all funds are listed in the table on page 1.

The broad U.S. taxable bond market registered a return of 0.30% for the 12 months, but this unremarkable result obscured extreme dislocations within the market. The strong performance of U.S. Treasury and government securities was offset by double-digit declines in the corporate bond market. These dynamics led to unusually large differences between the yields of Treasuries and their corresponding private-sector securities—both a reflection and a cause of the credit market’s distress.

Despite their generally high credit-worthiness, municipal bonds also fell in price, driving yields higher. The broad tax-exempt market registered a 12-month return of –3.30%. At the close of the period, municipal securities yielded more than U.S. Treasuries of similar maturities, an inversion of the typical relationship. On a taxable-equivalent basis, municipal yields were unusually high.

The U.S. Federal Reserve Board responded to the turmoil with new lending programs and a dramatic easing of monetary policy. Over the full 12 months, the Fed reduced its target for the federal funds rate from 4.50% to 1.00%.

Global stock markets started the 12-month period near all-time highs, but then declined sharply, laid low by the financial crisis that originated in the fixed income markets. The descent traced a series of jagged ups and downs. During the week ended October 10, for example, the U.S. stock market returned about –18%. When Wall Street opened the following Monday, stocks surged, returning more than 10% over the next six and a half hours.

For the full 12 months, the broad U.S. stock market returned –36.43%; international stocks returned –48.27%. The pain was especially acute in emerging markets—among the strongest performers in recent years—as investors became increasingly risk-averse.

A year ago, trouble in the fixed income markets seemed largely contained to securities backed by subprime mortgages, which came under severe pressure as the housing market deteriorated. As the depth and extent of the subprime market’s weakness became clear, however, distress spread to just about every segment of the fixed income market, including municipal securities.

Prices fell, and yields rose, for all but the shortest-term municipal securities. The performance of the seven Vanguard Municipal Bond Funds reflected these dynamics. The Short-Term, Limited-Term, and Money Market Tax-Exempt Funds produced positive 12-month returns; the rest of the portfolios delivered negative returns, as declining share prices more than offset the funds’ income returns.

Although the funds’ absolute returns were generally disappointing, all seven outperformed the average returns of their peer groups by substantial margins. These differences reflect Vanguard Fixed Income Group’s long-standing focus on high-quality securities and prudent portfolio management strategies, which helped protect shareholders from the worst of the market’s upheaval during the past year.

Vanguard High-Yield Tax-Exempt Fund’s Investor Shares returned –8.20% (Admiral Shares, –8.14%), the worst 12-month performance of the group. As investors retreated from risk, higher-yielding securities, which are generally issued by weaker borrowers, were hit hard, both in the taxable and tax-exempt markets.

Investors also hesitated to lock up their capital in longer-term securities. The share prices of the Insured Long-Term Tax-Exempt and Long-Term Tax-Exempt Funds fell by about –9%. After accounting for their income, the Insured Long-Term Fund’s Investor Shares returned –4.85% (Admiral Shares, –4.78%), and the Long-Term Fund’s Investor Shares returned –4.74% (Admiral Shares, –4.68%). The Intermediate-Term Tax-Exempt Fund registered a modestly negative return.

After the close of the period, we announced that the Insured Long-Term Tax-Exempt Fund would merge with the Long-Term Tax-Exempt Fund on December 12. The ratings agencies downgraded several municipal bond insurers during the past year, and the yields of insured and uninsured high-quality bonds began to converge, suggesting that investors were placing virtually no value on the insurance. The situation created little incentive for issuers to obtain insurance, and limited the benefits of a fund focused solely on insured bonds.

Vanguard Short-Term Tax-Exempt Fund’s Investor Shares returned 3.68% (Admiral Shares, +3.76%), the best 12-month result of the seven funds, followed by the Limited-Term Tax-Exempt Fund and the Tax-Exempt Money Market Fund, respectively. In October, the Vanguard Money Market Funds, including the Tax-Exempt Money Market Fund, elected to participate in the U.S. Treasury’s Temporary Guarantee Program for Money Market Funds. We have the highest confidence in the stability and liquidity of our money market funds, and we do not believe the funds will ever need support. We reasoned that our participation in the program could help bring stability to the credit markets, a development that would help Vanguard and other money market investors.

Just as they did during the past 12 months, the advisor’s diligent credit analysis, emphasis on high quality and liquidity, and efforts to keep the portfolios’ exposure to interest rate risk generally in line with that of their respective market segments have led to peer-beating returns over the past ten years.

The funds’ performance has also benefited from the funds’ low costs, which enhance your share of the funds’ rewards.

As stock markets have tumbled, and even typically staid segments of the investment markets such as municipal securities have experienced high levels of volatility, the temptation to “do something” has no doubt been strong. Our experience suggests that, more often than not, acting on such an emotional response is counterproductive.

We’ve found that a sensible approach to turbulent markets—and it’s worth noting that, while extreme, the recent turmoil is not unprecedented—is to determine a mix of stock, bond, and money market funds appropriate for your goals and circumstances, and then stick with it through the good times and bad. A balanced, well-diversified portfolio provides you with both some protection from the stock market’s deepest swoons and the opportunity to participate in its potential for long-term growth.

The Vanguard Municipal Bond Funds can play an important role in such a portfolio, particularly for investors in high tax brackets.

The figures shown represent past performance, which is not a guarantee of future results. (Current performance may be lower or higher than the performance data cited.

Note, too, that both investment returns and principal value can fluctuate widely, so an investor’s shares, when sold, could be worth more or less than their original cost.

For the fiscal year ended October 31, 2008, the Vanguard Municipal Bond Funds posted returns that ranged from a high of 3.76% for the Admiral Shares of the Short-Term Tax-Exempt Fund to a low of –8.20% for the Investor Shares of the High-Yield Tax-Exempt Fund. All seven funds outperformed the average returns of their peers.

Although market liquidity began to deteriorate in late 2007, significant changes in the municipal bond market started in early 2008 with downgrades in the credit ratings of the monoline municipal bond insurers, a reflection of their exposure to complex mortgage securities that lost significant value. At that time, roughly 50% of the outstanding market was guaranteed by an “AAA” insurance wrap underwritten by the insurers. As the insurers were downgraded, the prices of municipal bonds quickly traded to reflect the underlying credit quality, essentially discounting the value of the insurance.

This change had a ripple effect across the municipal market. Nontraditional investors, such as hedge funds that had bought previously AAA-rated municipal bonds with borrowed money, were forced to sell these assets (to meet margin requirements) as bond prices drifted lower. This selling, in turn, put additional pressure on prices. The auction-rate preferred market, a mechanism that had helped issuers borrow long-term money at shorter-term rates, essentially shut down, draining more liquidity from the market.

The net effect was a sell-off in municipals. It created a bifurcated market, with adequate liquidity for AA or higher-rated general obligation bonds and essential service credits, but scarce interest in lower-rated securities. The difference between the yields of higher- and lower-quality bonds widened. A by-product of these developments was a sharp drop in new issuance.

The municipal market’s turbulence also led to a historic increase in the ratio of municipal bond yields to those of U.S. Treasuries. At the end of October, for example, a 5-year AAA-rated general-obligation municipal bond yielded about 20% more than a 5-year Treasury. On an after-tax basis, the muni’s advantage was even greater. The municipal market’s significant value relative to Treasuries led to a surge in buying by individual investors.

Vanguard Fixed Income Group has always looked through the insurance wrapper to the underlying quality of the municipal issuer. As the monoline insurers were downgraded, this long-standing approach proved beneficial, limiting our exposure to bonds that were repriced by the market to reflect their lower underlying credit quality. As usual, we maintained a robust credit-analysis process and quality bias in our purchases, which helped us avoid some of the market’s pitfalls for the fiscal year.

Although we had a small amount of negative performance from our attempts to exploit the unusually large spread between municipal and Treasury yields, the funds didn’t pursue leveraged strategies or wade into lower-quality issues in an effort to enhance income. For the year, the funds’ durations were slightly below their typical levels. This positioning had a small impact on relative performance.

As of the close of fiscal 2008, the municipals market was returning to a more normalized environment. Over the past 12 months, much of the volatility has been driven by liquidity constraints in a selling market. Going forward, we will have to pay close attention to credit dynamics. Many state and local governments are dealing with tax shortfalls and budget gaps. Issuer credit quality will become more of a focus for the market over the coming year. Also, there is a backlog in new issuance, which could lead to a big increase in supply over the next few months.

We approach the new fiscal year confident that shareholders can rely on the Vanguard Municipal Bond Funds’ broad diversification and our experienced credit-research team to take advantage of the opportunities that arise in the municipal market. And as always, the muni funds’ low expense ratios enhance our clients’ share of the returns produced by these efforts.

Vanguard Tax-Exempt Money Market Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in debt instruments of many municipal issuers; the issuers’ abilities to meet their obligations may be affected by economic and political developments in a specific state or region.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. mutual funds. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Investment securities are valued at amortized cost, which approximates market value. Investments in Vanguard Municipal Cash Management Fund are valued at that fund’s net asset value.

2. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its income. Management has analyzed the fund’s tax positions taken on federal income tax returns for all open tax years (tax years ended October 31, 2005–2008), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

3. Distributions: Dividends from net investment income are declared daily and paid on the first business day of the following month.

4. Other: Interest income includes income distributions received from Vanguard Municipal Cash Management Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At October 31, 2008, the fund had contributed capital of $2,153,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 2.15% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s custodian bank has agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended October 31, 2008, custodian fee offset arrangements reduced the fund’s expenses by $103,000 (an annual rate of 0.00% of average net assets).

D. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards 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.

The various inputs that may be used to determine the value of the fund’s investments are summarized in three broad levels. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those 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 following table summarizes the fund’s investments as of October 31, 2008, based on the inputs used to value them:

The majority of the fund’s investments were valued using amortized cost, in accordance with rules under the Investment Company Act of 1940. Amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, securities valued at amortized cost are considered to be valued using Level 2 inputs.

E. On October 7, 2008, the board of trustees approved the fund’s participation in a temporary program introduced by the U.S. Treasury to guarantee the account values of shareholders in a money market fund in the event the fund’s net asset value falls below $0.995 and the fund’s trustees decide to liquidate the fund. The program covers the lesser of a shareholder’s account value on September 19, 2008, or on the date of liquidation. To participate, the fund is required to pay a fee of 0.01% of its net assets as of September 19, 2008, for coverage that lasts until December 18, 2008. The fund is accruing this expense over the period October 7–December 18, 2008. Through October 31, 2008, the fund has accrued $1,092,000, resulting in a 0.005% increase in the fund’s expense ratio for the year ended October 31, 2008. In December 2008, the U.S. Treasury extended the program through April 30, 2009, and the fund’s trustees approved the fund’s continuing participation in the program. To continue coverage for the period December 19, 2008–April 30, 2009, the fund will be required to pay an additional 0.015% of its net assets as of September 19, 2008.

3 30-day SEC yield for the fund; index yield assumes that all bonds are called or prepaid at the earliest possible dates. See the Glossary.

5 The expense ratios shown are from the prospectus dated July 29, 2008. For the fiscal year ended October 31, 2008, the expense ratios were 0.15% for Investor Shares and 0.08% for Admiral Shares.

Vanguard Short-Term Tax-Exempt Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in debt instruments of many municipal issuers; the issuers’ abilities to meet their obligations may be affected by economic and political developments in a specific state or region. The fund offers two classes of shares, Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, tenure, and account-size criteria.

1. Security Valuation: 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 Municipal Cash Management 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 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.

2. Futures Contracts: The fund uses futures contracts to invest in fixed income asset classes with greater efficiency and lower cost than is possible through direct investment, to add value when these instruments are attractively priced, or to adjust sensitivity to changes in interest rates. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of bonds held by the fund and the prices of futures contracts, and the possibility of an illiquid market.

Futures contracts are valued based upon their quoted daily settlement prices. The aggregate principal amounts of the contracts are not recorded in the Statement of Net Assets. Fluctuations in the value of the contracts are recorded in the Statement of Net Assets as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized futures gains (losses).

3. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute all of its income. Management has analyzed the fund’s tax positions taken on federal income tax returns for all open tax years (tax years ended October 31, 2005–2008), and has concluded that no provision for federal income tax is required in the fund’s financial statements.

4. Distributions: Distributions from net investment income are declared daily and paid on the first business day of the following month. Annual distributions from realized capital gains, if any, are recorded on the ex-dividend date.

5. Other: Interest income includes income distributions received from Vanguard Municipal Cash Management Fund and is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At October 31, 2008, the fund had contributed capital of $470,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.47% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. Capital gain distributions are determined on a tax basis and may differ from realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when gains or losses are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future.

For tax purposes, at October 31, 2008, the fund had available realized losses of $8,100,000 to offset future net capital gains of $1,354,000 through October 31, 2013, $3,801,000 through October 31, 2014, and $2,945,000 through October 31, 2015.

The fund had realized losses totaling $397,000 through October 31, 2008, which are deferred for tax purposes and reduce the amount of tax-basis unrealized appreciation on investment securities.

At October 31, 2008, the cost of investment securities for tax purposes was $5,044,315,000. Net unrealized appreciation of investment securities for tax purposes was $9,795,000, consisting of unrealized gains of $26,259,000 on securities that had risen in value since their purchase and $16,464,000 in unrealized losses on securities that had fallen in value since their purchase.

At October 31, 2008, the aggregate settlement value of open futures contracts expiring in December 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.

D. During the year ended October 31, 2008, the fund purchased $1,857,468,000 of investment securities and sold $1,052,971,000 of investment securities, other than temporary cash investments.

F. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards 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.

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 following table summarizes the fund’s investments as of October 31, 2008, based on the inputs used to value them.

3 30-day SEC yield for the fund; index yield assumes that all bonds are called or prepaid at the earliest possible dates. See the Glossary.

5 The expense ratios shown are from the prospectus dated July 29, 2008. For the fiscal year ended October 31, 2008, the expense ratios were 0.15% for Investor Shares and 0.08% for Admiral Shares.

Vanguard Insured Long-Term Tax-Exempt Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund invests in debt instruments of many municipal issuers; the issuers’ abilities to meet their obligations may be affected by economic and political developments in a specific state or region. The fund offers two classes of shares, Investor Shares and Admiral Shares. Investor Shares are available to any investor who meets the fund’s minimum purchase requirements. Admiral Shares are designed for investors who meet certain administrative, service, tenure, and account-size criteria.

1. Security Valuation: 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 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.

5. Other: Interest income is accrued daily. Premiums and discounts on debt securities purchased are amortized and accreted, respectively, to interest income over the lives of the respective securities. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

B. The Vanguard Group furnishes at cost investment advisory, corporate management, administrative, marketing, and distribution services. The costs of such services are allocated to the fund under methods approved by the board of trustees. The fund has committed to provide up to 0.40% of its net assets in capital contributions to Vanguard. At October 31, 2008, the fund had contributed capital of $305,000 to Vanguard (included in Other Assets), representing 0.01% of the fund’s net assets and 0.30% of Vanguard’s capitalization. The fund’s trustees and officers are also directors and officers of Vanguard.

C. The fund’s investment advisor may direct new-issue purchases, subject to obtaining the best price and execution, to underwriters who have agreed to rebate or credit to the fund part of the underwriting fees generated. Such rebates or credits are used solely to reduce the fund’s management and administrative expenses. The fund’s custodian bank has also agreed to reduce its fees when the fund maintains cash on deposit in the non-interest-bearing custody account. For the year ended October 31, 2008, these arrangements reduced the fund’s management and administrative expenses by $16,000 and custodian fees by $18,000. The total expense reduction represented an annual effective rate of 0.00% of the fund’s average net assets.

D. Capital gain distributions are determined on a tax basis and may differ from realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when gains or losses are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future.

For tax purposes, at October 31, 2008, the fund had available realized losses of $14,857,000 to offset future net capital gains through October 31, 2016.

The fund had realized losses totaling $14,017,000 through October 31, 2008, which are deferred for tax purposes and reduce the amount of tax-basis unrealized appreciation on investment securities.

At October 31, 2008, the cost of investment securities for tax purposes was $3,394,512,000. Net unrealized depreciation of investment securities for tax purposes was $201,992,000, consisting of unrealized gains of $52,084,000 on securities that had risen in value since their purchase and $254,076,000 in unrealized losses on securities that had fallen in value since their purchase.

At October 31, 2008, the aggregate settlement value of open futures contracts expiring in December 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.

E. During the year ended October 31, 2008, the fund purchased $861,887,000 of investment securities and sold $761,202,000 of investment securities, other than temporary cash investments.

G. In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards 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.

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).

Each class of shares of the fund was exchanged for the like class of shares of the Long-Term Tax-Exempt Fund. The fund’s net assets of $2,935,954,000, including $328,828,000 of unrealized depreciation, were combined with the Long-Term Tax-Exempt Fund’s net assets of $2,825,457,000, resulting in Long-Term Tax-Exempt Fund net assets of $5,761,411,000 immediately following the acquisition of the fund.

The following table summarizes the fund’s investments as of October 31, 2008, based on the inputs used to value them:

To the Trustees of Vanguard Municipal Bond Funds and the Shareholders of Vanguard Tax-Exempt Money Market Fund, Vanguard Short-Term Tax-Exempt Fund, Vanguard Limited-Term Tax-Exempt Fund, Vanguard Intermediate-Term Tax-Exempt Fund, Vanguard Insured Long-Term Tax-Exempt Fund, Vanguard Long-Term Tax-Exempt Fund and Vanguard High-Yield Tax-Exempt Fund:

In our opinion, the accompanying statements of net assets appearing in the insert to this Annual Report and the accompanying related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Vanguard Tax-Exempt Money Market Fund, Vanguard Short-Term Tax-Exempt Fund, Vanguard Limited-Term Tax-Exempt Fund, Vanguard Intermediate-Term Tax-Exempt Fund, Vanguard Insured Long-Term Tax-Exempt Fund, Vanguard Long-Term Tax-Exempt Fund and Vanguard High-Yield Tax-Exempt Fund (separate portfolios of Vanguard Municipal Bond Funds, hereafter referred to as the “Funds”) at October 31, 2008, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2008 by correspondence with the custodian and brokers, and by agreement to the underlying ownership records for Vanguard Municipal Cash Management Fund, provide a reasonable basis for our opinion.

This information for the fiscal year ended October 31, 2008, is included pursuant to provisions of the Internal Revenue Code.

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from the fund’s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading “Expenses Paid During Period.”

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund’s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include the account service fee described in the prospectus. If such a fee were applied to your account, your costs would be higher. Your fund does not charge transaction fees, such as purchase or redemption fees, nor does it carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

1 The calculations are based on expenses incurred in the most recent six-month period. The funds’ annualized six-month expense ratios for that period are: for the Tax-Exempt Money Market Fund, 0.11%; for the Short-Term Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares; for the Limited-Term Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares; for the Intermediate-Term Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares; for the Insured Long-Term Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares; for the Long-Term Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares; and for the High-Yield Tax-Exempt Fund, 0.15% for Investor Shares and 0.08% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period.

Average Coupon. The average interest rate paid on the fixed income securities held by a fund. It is expressed as a percentage of face value.

Average Duration. An estimate of how much the value of the bonds held by a fund will fluctuate in response to a change in interest rates. To see how the value could change, multiply the average duration by the change in rates. If interest rates rise by 1 percentage point, the value of the bonds in a fund with an average duration of five years would decline by about 5%. If rates decrease by a percentage point, the value would rise by 5%.

Average Effective Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid, taking into consideration the possibility that the issuer may call the bond before its maturity date. The figure reflects the proportion of fund assets represented by each security; it also reflects any futures contracts held. In general, the longer the average effective maturity, the more a fund’s share price will fluctuate in response to changes in market interest rates.

Average Quality. An indicator of credit risk, this figure is the average of the ratings assigned to a fund’s holdings by credit-rating agencies. The agencies make their judgment after appraising an issuer’s ability to meet its obligations. Quality is graded on a scale, with AAA indicating the most creditworthy bond issuers and MIG-1, A-1+, SP-1+, and F-1+ indicating the most creditworthy issuers of money market securities.

Average Weighted Maturity. The average length of time until fixed income securities held by a fund reach maturity and are repaid. The figure reflects the proportion of fund assets represented by each security.

Beta. A measure of the magnitude of a fund’s past share-price fluctuations in relation to the ups and downs of a given market index. The index is assigned a beta of 1.00. Compared with a given index, a fund with a beta of 1.20 typically would have seen its share price rise or fall by 12% when the index rose or fell by 10%. For this report, beta is based on returns over the past 36 months for both the fund and the index. Note that a fund’s beta should be reviewed in conjunction with its R-squared (see definition). The lower the R-squared, the less correlation there is between the fund and the index, and the less reliable beta is as an indicator of volatility.

Equity Exposure. A measure that reflects a fund’s investments in stocks and stock futures. Any holdings in short-term reserves are excluded.

Expense Ratio. The percentage of a fund’s average net assets used to pay its annual administrative and advisory expenses. These expenses directly reduce returns to investors.

Inception Date. The date on which the assets of a fund (or one of its share classes) are first invested in accordance with the fund’s investment objective. For funds with a subscription period, the inception date is the day after that period ends. Investment performance is measured from the inception date.

R-Squared. A measure of how much of a fund’s past returns can be explained by the returns from the market in general, as measured by a given index. If a fund’s total returns were precisely synchronized with an index’s returns, its R-squared would be 1.00. If the fund’s returns bore no relationship to the index’s returns, its R-squared would be 0. For this report, R-squared is based on returns over the past 36 months for both the fund and the index.

Short-Term Reserves. The percentage of a fund invested in highly liquid, short-term securities that can be readily converted to cash.

Yield. A money market fund’s 7-day SEC yield is calculated by annualizing its income distributions for the previous seven days, as required by the U.S. Securities and Exchange Commission. For other funds, 30-day SEC yield is derived using a formula specified by the commission. Under the formula, data related to the fund’s security holdings in the previous 30 days are used to calculate the fund’s hypothetical net income for that period, which is then annualized and divided by the fund’s estimated average net assets over the calculation period. For the purposes of this calculation, a security’s income is based on its current market yield to maturity (in the case of bonds) or its projected dividend yield (for stocks). Because the SEC yield represents hypothetical annualized income, it will differ—at times significantly—from the fund’s actual experience. As a result, the fund’s income distributions may be higher or lower than implied by the SEC yield.

Yield to Maturity. The rate of return an investor would receive if the fixed income securities held by a fund were held to their maturity dates.

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them on an at-cost basis.

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service.

Each trustee serves a fund until its termination; or until the trustee’s retirement, resignation, or death; or otherwise as specified in the fund’s organizational documents. Any trustee may be removed at a shareholders’ meeting by a vote representing two-thirds of the net asset value of all shares of the fund together with shares of other Vanguard funds organized within the same trust. The table below shows information for each trustee and executive officer of the fund. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

In making a determination, the Audit Committee considers whether the services are consistent with maintaining the principal accountant’s independence.

In the event of a contingency situation in which the principal accountant is needed to provide services in between scheduled Audit Committee meetings, the Chairman of the Audit Committee would be called on to consider and, if appropriate, pre-approve audit or permitted non-audit services in an amount sufficient to complete services through the next Audit Committee meeting, and to determine if such services would be consistent with maintaining the accountant’s independence.

The Audit Committee would again consider whether such services and fees are consistent with maintaining the principal accountant’s independence.

(f) For the most recent fiscal year, over 50% of the hours worked under the principal accountant’s engagement were not performed by persons other than full-time, permanent employees of the principal accountant.

Includes fees billed for non-audit services provided to the Registrant, The Vanguard Group, Inc., Vanguard Marketing Corporation, and other registered investment companies in the Vanguard Group.

(h) For the most recent fiscal year, the Audit Committee has determined that the provision of all non-audit services was consistent with maintaining the principal accountant’s independence.
