Investor Shares

Vanguard Mid-Cap Growth Fund ()

This prospectus contains financial data for the Fund through the fiscal year ended October 31, 2009.

The Securities and Exchange Commission has not approved or disapproved these securities or passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Fund Summary

Investment Objective

The Fund seeks to provide long-term capital appreciation.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy and hold shares of the Fund.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was xx% of the average value of its portfolio.

Primary Investment Strategies

The Fund invests at least 80% of its assets primarily in common stocks of medium-size companies. In selecting investments, each advisor invests in those medium-size companies that it believes have the best prospects for future growth. The Fund uses multiple investment advisors.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund’s performance could be hurt by:

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

• Investment style risk, which is the chance that returns from mid-capitalization growth stocks will trail returns from the overall stock market. Historically, mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. Mid-cap stocks tend to have greater volatility than large-cap stocks because, among other things, medium-size companies are more sensitive to changing economic conditions.

• Manager risk, which is the chance that poor security selection or focus on securities in
• particular sector, category, or group of companies will cause the Fund to underperform

relevant benchmarks or other funds with a similar investment objective.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund.* The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns compare with those of a relevant market index. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at www.vanguard.com/performance or by calling Vanguard toll-free 800-662-7447.

* Prior to June 29, 2002, Vanguard Mid-Cap Growth Fund was organized as Provident Investment Counsel Mid Cap Fund A (PIC Fund) and was sponsored by Provident Investment Counsel, Inc. A reorganization brought the Fund into The Vanguard Group; the investment objective, risks, and policies of the Fund remain substantially similar.

Annual Total Returns—Investor Shares

NO CHART DATA

During the periods shown in the bar chart, the highest return for a calendar quarter was XX.XX% (quarter ended xxxx), and the lowest return for a quarter was XX.XX% (quarter ended xxxx).

3

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Tax Information

The Fund’s distributions may be taxable as ordinary income or capital gains. Distributions are taxable to you for federal income tax purposes, whether or not you reinvest these amounts in additional Fund shares. A sale or exchange of Fund shares is a taxable event, which means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your federal income tax return. Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may also be subject to state and local income taxes.

Financial Intermediary Compensation

The Fund and its investment advisors do not pay financial intermediaries for sales of Fund shares or related services.

More on the Fund

This prospectus describes the primary risks you would face as a Fund shareholder. It is important to keep in mind one of the main axioms of investing: The higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: The lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk^® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted from a fund’s gross income, are expressed as a percentage of the net assets of the fund. Vanguard Mid-Cap Growth Fund’s expense ratio in fiscal year 2009 was xx.xx%, or $xx.xx per $1,000 of average net assets. The average expenses for mid-cap growth funds in 2008 were xx.xx%, or $xx.xx per $1,000 of average net assets (derived from data provided by Lipper Inc., which reports on the mutual fund industry). Management expenses, which are one part of operating expenses, include investment advisory fees as well as other costs of managing a fund—such as account maintenance, reporting, accounting, legal, and other administrative expenses.

5

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That’s because you, as a shareholder, pay the costs of operating a fund, plus any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund’s performance.

The following sections explain the primary investment strategies and policies that the Fund uses in pursuit of its objective. The Fund’s board of trustees, which oversees the Fund’s management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. Note that the Fund’s investment objective is not fundamental and may be changed without a shareholder vote.

Market Exposure

The Fund invests at least 80% of its assets primarily in common stocks of medium-size companies. Market capitalizations are within the capitalization range of the companies included in the Russell Midcap Growth Index ($xxx million to $xx.x billion as of October 31, 2009). The Fund may change its 80% policy only upon 60 days’ notice to shareholders. Additionally, in selecting investments, each advisor invests in those medium-size companies that it believes have the best prospects for future growth. However, the Fund has the flexibility to invest the balance of its assets in common stocks with other market capitalizations and in other security types.

Plain Talk About Growth Funds and Value Funds

Growth investing and value investing are two styles employed by stock-fund managers. Growth funds generally focus on stocks of companies believed to have above-average potential for growth in revenue, earnings, cash flow, or other similar criteria. These stocks typically have low dividend yields and above-average prices in relation to such measures as earnings and book value. Value funds typically emphasize stocks whose prices are below average in relation to those measures; these stocks often have above-average dividend yields. Growth and value stocks have historically produced similar long-term returns, though each category has periods when it outperforms the other.

6

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

To illustrate the volatility of stock prices, the following table shows the best, worst, and average annual total returns for the U.S. stock market over various periods as measured by the Standard & Poor‘s 500 Index, a widely used barometer of market activity. (Total returns consist of dividend income plus change in market price.) Note that the returns shown do not include the costs of buying and selling stocks or other expenses that a real-world investment portfolio would incur.

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through 2008. You can see, for example, that although the average return on common stocks for all of the 5-year periods was 10.3%, average returns for individual 5-year periods ranged from –12.4% (from 1928 through 1932) to 28.6% (from 1995 through 1999). These average returns reflect past performance of common stocks; you should not regard them as an indication of future performance of either the stock market as a whole or the Fund in particular.

The Fund is subject to investment style risk, which is the chance that returns from mid-capitalization growth stocks will trail returns from the overall stock market. Historically, mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. Mid-cap stocks tend to have greater volatility than large-cap stocks because, among other things, medium-size companies are more sensitive to changing economic conditions.

Stocks of publicly traded companies and funds that invest in stocks are often classified according to market value, or market capitalization. These classifications typically include small-cap, mid-cap, and large-cap. It’s important to understand that, for both companies and stock funds, market-capitalization ranges change over time. Also, interpretations of size vary, and there are no “official” definitions of small-, mid-, and large-cap, even among Vanguard fund advisors. The asset-weighted median market capitalization of the Fund as of October 31, 2009, was $xx.x billion.

7

Security Selection

The Fund uses multiple investment advisors. Each advisor independently selects and maintains a portfolio of common stocks for the Fund.

These advisors employ active investment management methods, which means that securities are bought and sold according to the advisors’ evaluations of companies and their financial prospects, the prices of the securities, and the stock market and the economy in general. Each advisor will sell a security when it is no longer as attractive as an alternative investment.

William Blair & Company, L.L.C. (William Blair & Company), which manages approximately xx% of the Fund’s assets, employs a fundamental, bottom-up stock selection process based on the market-cap range of the Russell Midcap Growth Index. William Blair & Company provides a concentrated portfolio (approximately 60 stocks) of high-quality growth stocks of companies that the advisor believes have superior, long-term earnings growth potential, combined with a proven and sustainable competitive advantage from market/brand position, technology position, or a unique asset base. William Blair & Company focuses on growth-oriented investing, fundamental research, and the depth of its investment team, which are its key strengths.

Chartwell Investment Partners, L.P. (Chartwell), which manages approximately xx% of the Fund’s assets, invests in companies that demonstrate strong earnings-per-share growth and, the advisor believes, have strong competitive positions and products, while serving a meaningful customer base. Chartwell will invest opportunistically when stocks are attractively valued, yet it will concentrate holdings in those companies it considers best positioned for rapid growth, all with an intermediate-term time horizon in mind.

Chartwell’s research process is “bottom-up” driven. Chartwell uses analysis to identify companies in the mid-cap range with under appreciated growth potential, trading at attractive absolute and relative valuations. The result is a portfolio of 60 to 70 stocks for Chartwell.

The Vanguard Group, Inc. (Vanguard), manages a small portion, approximately xx%, of the Fund’s assets to facilitate cash flows to and from the Fund’s advisors. Vanguard typically invests its portion of the Fund’s assets in stock index futures and/or shares of exchange-traded funds. For more details, see “Other Investment Policies and Risks.”

The Fund is subject to manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

The Fund is generally managed without regard to tax ramifications.

Other Investment Policies and Risks

Although the Fund typically does not make significant investments in foreign securities, it reserves the right to invest up to 25% of its assets this way. Foreign securities may be traded on U.S. or foreign markets. To the extent that it owns foreign securities, the Fund is subject to country risk and currency risk. Country risk is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries. In addition, the prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions. Currency risk is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

The Fund may invest, to a limited extent, in derivatives. Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, bond, or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Investments in derivatives may subject the Fund to risks different from, and possibly greater than, those of the underlying securities, assets, or market indexes. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

The Fund may enter into forward foreign currency exchange contracts, which are types of derivative contracts. A forward foreign currency exchange contract is an agreement to buy or sell a country’s currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. In other words, the contract guarantees an exchange rate on a given date. Managers of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in U.S. dollar/foreign currency exchange rates. These contracts, however, would not prevent the Fund’s securities from falling in value during foreign market downswings.

Vanguard typically invests a small portion of the Fund’s assets in stock index futures and/or shares of exchange-traded funds (ETFs), including ETF Shares issued by Vanguard stock funds. Stock index futures and ETFs provide returns similar to those of common stocks. Vanguard may purchase futures or ETFs when doing so will reduce the Fund’s transaction costs or add value because the instruments are favorably priced. Vanguard receives no additional revenue from investing Fund assets in ETF Shares of other Vanguard funds. Fund assets invested in ETF Shares are excluded when allocating to the Fund its share of the costs of Vanguard operations.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds. When investing in a Vanguard CMT Fund, the Fund bears its proportionate share of the at-cost expenses of the CMT Fund in which it invests.

9

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when doing so is believed to be in the Fund’s best interest, so long as the alternative is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond the normal limits in derivatives or ETFs that are consistent with the Fund’s objective when those instruments are more favorably priced or provide needed liquidity, as might be the case when the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.

In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash, commercial paper, or other less volatile instruments—in response to adverse or unusual market, economic, political, or other conditions. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund’s shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, a fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor’s ability to efficiently manage the fund.

Policies to Address Frequent Trading. The Vanguard funds (other than money market funds, short-term bond funds, and Vanguard ETF™ Shares) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

• Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected if Vanguard determines that such purchase may negatively affect a fund’s operation or performance or because of a history of frequent trading by the investor.

10

• Each Vanguard fund (other than money market funds, short-term bond funds, and ETF Shares) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account.

• Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

See the Investing With Vanguard section of this prospectus for further details on Vanguard’s transaction policies.

Each fund (other than money market funds), in determining its net asset value, will, when appropriate, use fair-value pricing, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund normally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. The average turnover rate for mid-cap growth funds was approximately xx%, as reported by Morningstar, Inc., on October 31, 2009.

Plain Talk About Turnover Rate

Before investing in a mutual fund, you should review its turnover rate. This gives an indication of how transaction costs, which are not included in the fund’s expense ratio, could affect the fund’s future returns. In general, the greater the volume of buying and selling by the fund, the greater the impact that brokerage commissions and other transaction costs will have on its return. Also, funds with high turnover rates may be more likely to generate capital gains that must be distributed to shareholders as taxable income.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of 37 investment companies with more than 160 funds holding assets of approximately $1.2 trillion. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, equipment, and advertising.

11

Vanguard also provides marketing services to the funds. Although shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of the fund (in the case of a fund with multiple share classes) pays its allocated share of The Vanguard Group’s marketing costs.

Plain Talk About Vanguard’s Unique Corporate Structure

The Vanguard Group is truly a mutual mutual fund company. It is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that may be owned by one person, by a private group of individuals, or by public investors who own the management company’s stock. The management fees charged by these companies include a profit component over and above the companies’ cost of providing services. By contrast, Vanguard provides services to its member funds on an at-cost basis, with no profit component, which helps to keep the funds’ expenses low.

Investment Advisors

The Fund uses a multimanager approach. Each advisor independently manages its assigned portion of the Fund’s assets, subject to the supervision and oversight of Vanguard and the Fund’s board of trustees. The board of trustees designates the proportion of Fund assets to be managed by each advisor and may change these proportions at any time.

• William Blair & Company, L.L.C., 222 West Adams Street, Chicago, IL 60606, is an independently owned full-service investment management firm founded in 1935. The firm manages assets for mutual funds, public and private employee benefit plans, foundations, endowments, institutions, and separate accounts. As of October 31, 2009, William Blair & Company managed approximately $xx billion in assets.

• Chartwell Investment Partners, L.P., 1235 Westlakes Drive, Suite 400, Berwyn, PA

19312, is an investment advisory firm founded in 1997. As of October 31, 2009, Chartwell managed approximately $xx billion in assets.

The Fund pays each of its investment advisors on a quarterly basis. Each advisor receives a base fee that is based on certain annual percentage rates applied to the average daily net assets managed by the advisor during the most recent fiscal quarter. The fee paid to each advisor may be increased or decreased based on the advisor’s performance compared with that of a benchmark index. For these purposes, the cumulative total return of the Fund is compared with that of the Russell Midcap Growth Index over a trailing 36–month period (60-month period for William Blair & Company). Please note that over time, changes in an advisor’s relative performance may result in

12

changes in the performance-based fees paid by the Fund, which in turn would result in an increase or decrease in the expenses borne by Fund shareholders.

For the fiscal year ended October 31, 2009, the aggregate advisory fee represented an effective annual rate of xx% of the Fund’s average net assets DETERMINE IN BL.

Under the terms of an SEC exemption, the Fund’s board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement or hire a new investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund’s advisory arrangements will be communicated to shareholders in writing. In addition, as the Fund’s sponsor and overall manager, The Vanguard Group may provide investment advisory services to the Fund, on an at-cost basis, at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced, or that the terms of an existing advisory agreement be revised.

For a discussion of why the board of trustees approved the Fund’s investment advisory agreements, see the most recent annual report to shareholders covering the fiscal year ended October 31.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest and dividends, less expenses) as well as any net capital gains realized from the sale of its holdings. Distributions generally occur annually in December. You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund’s income from interest and dividends as well as capital gains from the fund’s sale of investments. Income consists of both the dividends that the fund earns from any stock holdings and the interest it receives from any money market and bond investments. Capital gains are realized whenever the fund sells securities for higher prices than it paid for them. These capital gains are either short-term or long-term, depending on whether the fund held the securities for one year or less or for more than one year.

Basic Tax Points

Vanguard will send you a statement each year showing the tax status of all your distributions. In addition, investors in taxable accounts should be aware of the following basic federal income tax points:

• Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

• Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

• Any dividend and short-term capital gains distributions that you receive are taxable to you as ordinary income. If you are an individual and meet certain holding-period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on “qualified dividend income,”if any, distributed by the Fund.

• Any distributions of net long-term capital gains are taxable to you as long-term capital gains, no matter how long you’ve owned shares in the Fund.

14

• Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

• A sale or exchange of Fund shares is a taxable event. This means that you may have
• capital gain to report as income, or a capital loss to report as a deduction, when you

complete your tax return.

Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

This prospectus provides general tax information only. If you are investing through a tax-deferred retirement account, such as an IRA, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About ‘Buying a Dividend’

Unless you are investing through a tax-deferred retirement account (such as an IRA), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as “buying a dividend.” For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid “buying a dividend,” check a fund’s distribution schedule before you invest.

General Information

Backup withholding. By law, Vanguard must withhold 28% of any taxable distributions or redemptions from your account if you do not:

• Provide us with your correct taxpayer identification number;
• Certify that the taxpayer identification number is correct; and
• Confirm that you are not subject to backup withholding.

Similarly, Vanguard must withhold taxes from your account if the IRS instructs us to do so.

Foreign investors. Vanguard funds generally are not sold outside the United States, except to certain qualified investors. If you reside outside the United States, please consult our website at www.vanguard.com and review “Non-U.S. investors.” Foreign investors should be aware that U.S. withholding and estate taxes may apply to any investments in Vanguard funds.

15

Invalid addresses. If a dividend or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest all future distributions until you provide us with a valid mailing address.

Share Price

Share price, also known as net asset value (NAV), is calculated each business day as of the close of regular trading on the New York Stock Exchange, generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not transact purchase or redemption requests. However, on those days the value of the Fund’s assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open.

Stocks held by a Vanguard fund are valued at their market value when reliable market quotations are readily available. Certain short-term debt instruments used to manage a fund’s cash are valued on the basis of amortized cost. The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party. The values of any mutual fund shares held by a fund are based on the NAVs of the shares. The values of any ETF or closed-end fund shares held by a fund are based on the market value of the shares.

When a fund determines that market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security). A fund also will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the fund’s pricing time but after the close of the primary markets or exchanges on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges that close many hours before the fund’s pricing time. Intervening events might be company-specific (e.g., earnings report, merger announcement); country-specific (e.g., natural disaster, economic or political news, act of terrorism, interest rate change); or global. Intervening events include price movements in U.S. markets that are deemed to affect the value of foreign securities. Fair-value pricing may be used for domestic securities—for example, if (1) trading in a security is halted and does not resume before the fund’s pricing time or if a security does not trade in the course of a day, and (2) the fund holds enough of the security that its price could affect the NAV.

Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Financial Highlights

The following financial highlights table is intended to help you understand the Fund’s financial performance for the periods shown, and certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned or lost each period on an investment in the Fund (assuming reinvestment of all distributions). This information has been derived from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report—along with the Fund’s financial statements—is included in the Fund’s most recent annual report to shareholders. You may obtain a free copy of the latest annual or semiannual report online at www.vanguard.com or by contacting Vanguard by telephone or mail.

Plain Talk About How to Read the Financial Highlights Table

The Fund began fiscal year 2009 with a net asset value (price) of $xx.xx per share. During the year, the Fund earned $xx.xx per share from investment income (interest and dividends) and $xx.xx per share from investments that had appreciated in value or that were sold for higher prices than the Fund paid for them.

Shareholders received $xx.xx per share in the form of dividend and capital gains distributions. A portion of each year’s distributions may come from the prior year’s income or capital gains.

The share price at the end of the year was $xx.xx, reflecting earnings of $xx.xx per share and distributions of $xx.xx per share. This was an increase of $xx.xx per share (from $xx.xx at the beginning of the year to $xx.xx at the end of the year). For a shareholder who reinvested the distributions in the purchase of more shares, the total return was xx% for the year.

As of October 31, 2009, the Fund had approximately $xxx billion in net assets. For the year, the expense ratio was x.xx% ($x.xx per $1,000 of net assets), and the net investment income amounted to xx% of its average net assets. The Fund sold and replaced securities valued at xx% of its net assets.

1 Total returns do not include the account service fee that may be applicable to certain accounts with balances below $10,000.

2 Includes performance-based investment advisory fee increases (decreases) of 0.03%, 0.03%,(0.04%), (0.09%), and (0.05%).

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Be sure to carefully read each topic that pertains to your relationship with Vanguard. Vanguard reserves the right to change the following policies, without notice to shareholders. Please call or check online for current information.

Each fund you hold in an account is a separate “fund account.” For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open or maintain a fund account, or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

Account Minimums for Investor Shares

To open and maintain an account. $10,000; $3,000 for IRAs and most custodial accounts for minors.

Add to an existing account. $100 by check, exchange, wire, or electronic bank transfer (other than Automatic Investment Plan, which has no established minimum).

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limits, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange (the purchase of shares of one Vanguard fund using the proceeds of a simultaneous redemption from another Vanguard fund) through our website at www.vanguard.com if you are a registered user.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from your account statement), with a deposit slip (available online), or with a written request. You may also send a written request to Vanguard to make an exchange. For a list of Vanguard addresses, see Contacting Vanguard.

19

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer option on an account, you must designate the bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or from time to time. Your purchase request can be initiated online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may send a check to make initial or additional purchases to your fund account. Also see How to Initiate a Purchase Request: By mail. Make your check payable to Vanguard and include the appropriate fund number (Vanguard—301).

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the New York Stock Exchange (NYSE) is open for regular trading (a business day).

For purchases by check into all funds other than money market funds, and for purchases by exchange or wire into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market

20

mutual fund one business day to convert check proceeds into federal funds, the trade date will be one business day later than for other funds.

For purchases by electronic bank transfer using an Automatic Investment Plan: Your trade date generally will be one business day before the date you designated for withdrawal from your bank account.

For purchases by electronic bank transfer not using an Automatic Investment Plan: If the purchase request is received by Vanguard on a business day before 10 p.m., Eastern time, the trade date generally will be the next business day. If the purchase request is received on a business day after 10 p.m., Eastern time, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the request.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

Other Purchase Rules You Should Know

Check purchases. All purchase checks must be written in U.S. dollars and must be drawn on a U.S. bank. Vanguard does not accept cash, traveler’s checks, or money orders. In addition, Vanguard may refuse “starter checks” and checks that are not made payable to Vanguard.

New accounts. We are required by law to obtain from you certain personal information that we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your identity, Vanguard reserves the right, without notice, to close your account or take such other steps as we deem reasonable.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because of a history of frequent trading by the investor or because the purchase may negatively affect a fund’s operation or performance.

Large purchases. Please call Vanguard before attempting to invest a large dollar amount.

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

21

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limits, and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares and request an exchange (using the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund) through our website at www.vanguard.com if you are a registered user.

By telephone. You may call Vanguard to request a redemption of shares. See

Contacting Vanguard.

By mail. You may send a written request to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard.

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer option on an account, you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or from time to time. Your redemption request can be initiated online, by telephone, or by mail.

By wire. When redeeming from a money market fund or a bond fund, you may instruct Vanguard to wire your redemption proceeds ($1,000 minimum) to a previously designated bank account. Wire redemptions generally are not available for Vanguard’s balanced or stock funds. The wire redemption option is not automatic; you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form.

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are

22

redeeming. Your redemption will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the NYSE is open for regular trading (a business day).

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

• Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

• Note on timing of wire redemptions from bond funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer using an Automatic Withdrawal Plan: Your trade date generally will be the date you designated for withdrawal of funds (redemption of shares) from your Vanguard account. Proceeds of redeemed shares generally will be credited to your designated bank account two business days after your trade date. If the date you designated for withdrawal of funds from your Vanguard account falls on a weekend, holiday, or other nonbusiness day, your trade date will be the previous business day.

For redemptions by electronic bank transfer not using an Automatic Withdrawal Plan: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to

23

complete your transaction. If Vanguard is still unable to complete the transaction, we may use your proceeds to purchase new shares of the Fund in which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

For further information about redemption transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund’s operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limits for information about Vanguard’s policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to ten calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Share certificates. If you hold shares in certificates, those shares cannot be redeemed or exchanged until you return the certificates (unsigned) to Vanguard by registered mail. For the correct address, see Contacting Vanguard.

Address change. If you change your address online or by telephone, there may be a 15-day restriction on your ability to request redemptions online and by telephone. You can request a redemption in writing at any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require a signature guarantee. You may obtain a signature guarantee from

24

some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange. A notary public cannot provide a signature guarantee.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason.

Frequent-Trading Limits

Because excessive transactions can disrupt management of a fund and increase the fund’s costs for all shareholders, Vanguard places certain limits on frequent trading in the Vanguard funds. Each Vanguard fund (other than money market funds and short-term bond funds) limits an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to the frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the policy applies to exchanges made online or by phone.

The frequent-trading policy does not apply to the following:

• Purchases of shares with reinvested dividend or capital gains distributions.

25

• Transactions through Vanguard’s Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online^®.

• Redemptions of shares to pay fund or account fees.
• Transaction requests submitted by mail to Vanguard from shareholders who hold

their accounts directly with Vanguard. (Transaction requests submitted by fax, if otherwise permitted, are not mail transactions and are subject to the policy.)

• Transfers and reregistrations of shares within the same fund.
• Purchases of shares by asset transfer or direct rollover.
• Conversions of shares from one share class to another in the same fund.
• Checkwriting redemptions.
• Section 529 college savings plans.
• Certain approved institutional portfolios and asset allocation programs, as well as

trades made by Vanguard funds that invest in other Vanguard funds. (Please note that shareholders of Vanguard’s funds of funds are subject to the policy.)

For participants in employer-sponsored defined contribution plans,* the frequent-trading policy does not apply to:

• Purchases of shares with participant payroll or employer contributions or loan repayments.

• Purchases of shares with reinvested dividend or capital gains distributions.
• Distributions, loans, and in-service withdrawals from a plan.
• Redemptions of shares as part of a plan termination or at the direction of the plan.
• Automated transactions executed during the first six months of a participant’s

enrollment in the Vanguard Managed Account Program.

• Redemptions of shares to pay fund or account fees.
• Share or asset transfers or rollovers.
• Reregistrations of shares.
• Conversions of shares from one share class to another in the same fund.
• Exchange requests submitted by mail to Vanguard. (Exchange requests submitted

by fax, if otherwise permitted, are not mail requests and are subject to the policy.)

* The following Vanguard fund accounts are subject to the frequent-trading policy: SEP-IRAs, SIMPLE IRAs, certain Section 403(b)(7) accounts, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

26

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients’ accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client’s accounts the 60-day policy previously described, prohibiting a client’s purchases of fund shares, and/or revoking the client’s exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary’s clients. Intermediaries also may monitor their clients’ trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase or redemption fees, intermediaries will be asked to assess purchase and redemption fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent-trading policies may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading policies. If you invest with Vanguard through an intermediary, please read that firm’s materials carefully to learn of any other rules or fees that may apply.

Proof of a caller’s authority.

Before we allow a caller to act on an account, we may request the following information:

• Authorization to act on the account (as the account owner or by legal documentation or other means).

• Account registration and address.
• Fund name and account number, if applicable.
• Other information relating to the caller, the account owner, or the account.

Written instructions also must include:

• Signatures of all registered owners.
• Signature guarantees, if required for the type of transaction. (Call Vanguard for

Accounts With More Than One Owner

If an account has more than one owner or authorized person, Vanguard will accept telephone or online instructions from any one owner or authorized person.

Responsibility for Fraud

Vanguard will not be responsible for any account losses because of fraud if we reasonably believe that the person transacting business on an account is authorized to do so. Please take precautions to protect yourself from fraud. Keep your account information private, and immediately review any account statements that we provide to you. It is important that you contact Vanguard immediately about any transactions or changes to your account that you believe to be unauthorized.

Uncashed Checks

Please cash your distribution or redemption checks promptly. Vanguard will not pay interest on uncashed checks.

Unusual Circumstances

Contacting Vanguard for addresses.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, broker, or investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply.

Please see Frequent-Trading Limits—Accounts Held by Intermediaries for information about the assessment of redemption fees and monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

For most shareholders, Vanguard charges a $20 account service fee on all fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement

29

fund accounts and will be assessed on fund accounts in all Vanguard funds, regardless of a fund’s minimum investment amount. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from a fund account only once per calendar year.

If you register on Vanguard.com and elect to receive electronic delivery of statements, reports, and other materials for all of your fund accounts, the account service fee for balances below $10,000 will not be charged, so long as that election remains in effect.

The account service fee also does not apply to the following:

• Money market sweep accounts owned in connection with a Vanguard Brokerage Services^® account.

• Accounts held through intermediaries.
• Accounts held by Voyager, Voyager Select, and Flagship members. Membership is

based on total household assets held at Vanguard, with a minimum of $100,000 to qualify for Vanguard Voyager Services^®, $500,000 for Vanguard Voyager Select Services^®, and $1 million for Vanguard Flagship Services^®. Vanguard determines membership by aggregating assets of all eligible accounts held by the investor and immediate family members who reside at the same address. Aggregate assets include investments in Vanguard mutual funds, Vanguard ETFs™, annuities through Vanguard, the Vanguard 529 Plan, certain small-business accounts, and employer-sponsored retirement plans for which Vanguard provides recordkeeping services.

• Participant accounts in employer-sponsored defined contribution plans.* Please consult your enrollment materials for the rules that apply to your account.

• Section 529 college savings plans.
• The following Vanguard fund accounts have alternative fee structures: SIMPLE IRAs,

certain Section 403(b)(7) accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the minimum initial investment for any reason, including market fluctuation. This policy applies to nonretirement fund accounts and accounts that are held through intermediaries.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of

30

purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time; (2) accept initial purchases by telephone; (3) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners, or if we reasonably believe a fraudulent transaction may occur or has occurred; (4) temporarily freeze any account and/or suspend account services upon initial notification to Vanguard of the death of the shareholder until Vanguard receives required documentation in good order; (5) alter, impose, discontinue, or waive any redemption fee, account service fee, or other fees charged to a group of shareholders; and (6) redeem an account or suspend account privileges, without the owner’s permission to do so, in cases of threatening conduct or activity Vanguard believes to be suspicious, fraudulent, or illegal. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, we reasonably believe they are deemed to be in the best interest of a fund.

Fund and Account Updates

Confirmation Statements

We will send (or provide online, whichever you prefer) a confirmation of your trade date and the amount of your transaction when you buy, sell, or exchange shares. However, we will not send confirmations reflecting only checkwriting redemptions or the reinvestment of dividend or capital gains distributions. For any month in which you had a checkwriting redemption, a Checkwriting Activity Statement will be sent to you itemizing the checkwriting redemptions for that month. Promptly review each confirmation statement that we provide to you by mail or online. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on a confirmation statement, or Vanguard will consider the transaction properly processed.

Portfolio Summaries

We will send (or provide online, whichever you prefer) quarterly portfolio summaries to help you keep track of your accounts throughout the year. Each summary shows the market value of your account at the close of the statement period, as well as all distributions, purchases, redemptions, exchanges, and transfers for the current calendar year. Promptly review each summary that we provide to you by mail or online. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on the summary, or Vanguard will consider the transaction properly processed.

31

Tax Statements

For most accounts, we will send annual tax statements to assist you in preparing your income tax returns. These statements, which are generally mailed in January, will report the previous year’s dividends, capital gains distributions, proceeds from the sale of shares from taxable accounts, and distributions from IRAs and other retirement plans. Registered users can view these statements online.

Average-Cost Review Statements

For most taxable accounts, average-cost review statements will accompany annual Forms 1099-B. These statements show the average cost of shares that you redeemed during the previous calendar year, using the average-cost single-category method, which is one of the methods established by the IRS.

Annual and Semiannual Reports

We will send (or provide online, whichever you prefer) financial reports about Vanguard Mid-Cap Growth Fund twice a year, in June and December. These comprehensive reports include overviews of the financial markets and provide the following specific Fund information:

• Performance assessments and comparisons with industry benchmarks.
• Reports from the advisors.
• Financial statements with listings of Fund holdings.

Portfolio Holdings

We generally post on our website at www.vanguard.com, in the Portfolio section of the Fund’s Portfolio & Management page, a detailed list of the securities held by the Fund, as of the end of the most recent calendar quarter. This list is generally updated within 30 days after the end of each calendar quarter. Vanguard may exclude any portion of these portfolio holdings from publication when deemed in the best interest of the Fund. We also generally post the ten largest stock portfolio holdings of the Fund and the percentage of the Fund’s total assets that each of these holdings represents, as of the end of the most recent calendar quarter. This list is generally updated within 15 calendar days after the end of each calendar quarter. Please consult the Fund’s Statement of Additional Information or our website for a description of the policies and procedures that govern disclosure of the Fund’s portfolio holdings.

The expense ratio includes management expenses—such as advisory fees, account maintenance, reporting, accounting, legal, and other administrative expenses—and any 12b-1 distribution fees. It does not include the transaction costs of buying and selling portfolio securities.

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.

Median Market Capitalization. An indicator of the size of companies in which a fund invests; the midpoint of market capitalization (market price x shares outstanding) of a fund’s stocks, weighted by the proportion of the fund’s assets invested in each stock. Stocks representing half of the fund’s assets have market capitalizations above the median, and the rest are below it.

Mutual Fund. An investment company that pools the money of many people and invests it in a variety of securities in an effort to achieve a specific objective over time.

Principal. The face value of a debt instrument or the amount of money put into an investment.

Securities. Stocks, bonds, money market instruments, and other investment vehicles.

Total Return. A percentage change, over a specified time period, in a mutual fund’s net asset value, assuming the reinvestment of all distributions of dividends and capital gains.

Volatility. The fluctuations in value of a mutual fund or other security. The greater a fund’s volatility, the wider the fluctuations in its returns.

Yield. Income (interest or dividends) earned by an investment, expressed as a percentage of the investment’s price.

Fund Summary

Investment Objective

The Fund seeks to provide long-term capital appreciation and income.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy and hold shares of the Fund.

1 The 1% fee applies only if you redeem shares within one year of purchase by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because the balance falls below the minimum initial investment for any reason, including market fluctuation.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was xx% of the average value of its portfolio.

Primary Investment Strategies

The Fund invests mainly in the stocks of medium-size U.S. companies, choosing stocks considered by an advisor to be undervalued. Undervalued stocks are generally those that are out of favor with investors and are trading at prices that the advisor feels are below-average in relation to such measures as earnings and book value. These stocks often have above-average dividend yields. The Fund uses multiple investment advisors.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund’s performance could be hurt by:

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

• Investment style risk, which is the chance that returns from mid-capitalization value stocks will trail returns from the overall stock market. Historically, mid-capitalization value stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. Mid-cap stocks tend to have greater volatility than large-cap stocks because, among other things, medium-size companies are more sensitive to changing economic conditions.

• Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

• Asset concentration risk, which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of relatively few stocks.

2

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns compare with those of a relevant market index. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at www.vanguard.com/performance or by calling Vanguard toll-free at 800-662-7447.

Annual Total Returns—Investor Shares

NO CHART DATA

During the periods shown in the bar chart, the highest return for a calendar quarter was XX.XX% (quarter ended xxxx), and the lowest return for a quarter was XX.XX% (quarter ended xxxx).

3

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Tax Information

The Fund’s distributions may be taxable as ordinary income or capital gains. Distributions are taxable to you for federal income tax purposes, whether or not you reinvest these amounts in additional Fund shares. A sale or exchange of Fund shares is a taxable event, which means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your federal income tax return. Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may also be subject to state and local income taxes.

Financial Intermediary Compensation

The Fund and its investment advisors do not pay financial intermediaries for sales of Fund shares or related services.

More on the Fund

This prospectus describes the primary risks you would face as a Fund shareholder. It is important to keep in mind one of the main axioms of investing: The higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: The lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk^® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted from a fund’s gross income, are expressed as a percentage of the net assets of the fund. Vanguard Selected Value Fund’s expense ratio in fiscal year 2009 was xx%, or $x.xx per $1,000 of average net assets. The average expenses for mid-cap value funds in 2008 were x.xx%, or $x.xx per $1,000 of average net assets (derived from data provided by Lipper Inc., which reports on the mutual fund industry). Management expenses, which are one part of operating expenses, include investment advisory fees as well as other costs of managing a fund—such as account maintenance, reporting, accounting, legal, and other administrative expenses.

5

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That’s because you, as a shareholder, pay the costs of operating a fund, plus any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund’s performance.

The following sections explain the primary investment strategies and policies that the Fund uses in pursuit of its objective. The Fund’s board of trustees, which oversees the Fund’s management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental.

Market Exposure

The Fund invests mainly in common stocks of mid-cap companies that are considered to have low prices in relation to their corporate earnings and book value. These stocks often have above-average dividend yields.

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

To illustrate the volatility of stock prices, the following table shows the best, worst, and average annual total returns for the U.S. stock market over various periods as measured by the Standard & Poor‘s 500 Index, a widely used barometer of market activity. (Total returns consist of dividend income plus change in market price.) Note that the returns shown do not include the costs of buying and selling stocks or other expenses that a real-world investment portfolio would incur.

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through 2008.

You can see, for example, that although the average return on common stocks for all

6

of the 5-year periods was 10.3%, average returns for individual 5-year periods ranged from –12.4% (from 1928 through 1932) to 28.6% (from 1995 through 1999). These average returns reflect past performance of common stocks; you should not regard them as an indication of future performance of either the stock market as a whole or the Fund in particular.

Stocks of publicly traded companies and funds that invest in stocks are often classified according to market value, or market capitalization. These classifications typically include small-cap, mid-cap, and large-cap. It’s important to understand that, for both companies and stock funds, market-capitalization ranges change over time. Also, interpretations of size vary, and there are no “official” definitions of small-, mid-, and large-cap, even among Vanguard fund advisors. The asset-weighted median market capitalization of the Fund as of October 31, 2009, was $xx.x billion.

The Fund is subject to investment style risk, which is the chance that returns from mid-capitalization value stocks will trail returns from the overall stock market. Historically, mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently. Mid-cap stocks tend to have greater volatility than large-cap stocks because, among other things, medium-size companies are more sensitive to changing economic conditions.

Plain Talk About Growth Funds and Value Funds

Growth investing and value investing are two styles employed by stock-fund managers. Growth funds generally focus on stocks of companies believed to have above-average potential for growth in revenue, earnings, cash flow, or other similar criteria. These stocks typically have low dividend yields and above-average prices in relation to such measures as earnings and book value. Value funds typically emphasize stocks whose prices are below average in relation to those measures; these stocks often have above-average dividend yields. Growth and value stocks have historically produced similar long-term returns, though each category has periods when it outperforms the other.

Security Selection

The Fund uses multiple investment advisors. Each advisor independently selects and maintains a portfolio of common stocks for the Fund.

These advisors employ active investment management methods, which means that securities are bought and sold according to the advisors’ evaluations of companies and their financial prospects, the prices of the securities, and the stock market and

7

the economy in general. Each advisor will sell a security when it is no longer as attractive as an alternative investment.

Each advisor uses a different process to select securities for its portion of the Fund’s assets.

Barrow, Hanley, Mewhinney & Strauss, Inc. (Barrow, Hanley), which manages approximately xx% of the Fund’s assets, seeks out medium-size companies that it considers to be undervalued, choosing them on the basis of extensive research and discussions with company management. According to Barrow, Hanley, a company is undervalued if its earnings potential is not reflected in its share price. Barrow, Hanley looks for individual stocks that reflect these value characteristics: price/earnings and price/book value ratios below those of the market, as well as dividend yields above those of the market. Barrow, Hanley holds an undervalued stock until the advisor believes the stock’s price reflects the company’s underlying value.

Donald Smith & Co., Inc. (Donald Smith & Co.), which manages approximately xx% of the Fund’s assets, employs a strictly bottom-up investment approach that seeks out stocks of out-of-favor companies selling at discounts to tangible book value. Donald Smith & Co. looks for companies in the bottom decile of price-to-tangible-book value ratios that have positive outlooks for earnings potential over the next two to four years. Donald Smith & Co. employs traditional fundamental research techniques with the objective of determining the extent of earnings a company’s asset base can generate.

The Vanguard Group, Inc. (Vanguard), manages a small portion, approximately xx%, of the Fund’s assets to facilitate cash flows to and from the Fund’s advisors. Vanguard typically invests its portion of the Fund’s assets in stock index futures and/or shares of exchange-traded funds (ETFs). For more details, see “Other Investment Policies and Risks.”

Because the Fund tends to invest a high percentage of assets in its ten largest holdings, the Fund is subject to asset concentration risk, which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of relatively few stocks.

The Fund is subject to manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

The Fund is generally managed without regard to tax ramifications.

Other Investment Policies and Risks

Besides investing in U.S. mid-cap value stocks, the Fund may make other kinds of investments to achieve its objective.

8

Although the Fund typically does not make significant investments in foreign securities, it reserves the right to invest up to 25% of its assets this way. Foreign securities may be traded on U.S. or foreign markets. To the extent that it owns foreign securities, the Fund is subject to country risk and currency risk. Country risk is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries. In addition, the prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions. Currency risk is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

The Fund may invest, to a limited extent, in derivatives. Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, bond, or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Investments in derivatives may subject the Fund to risks different from, and possibly greater than, those of the underlying securities, assets, or market indexes. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

The Fund may enter into forward foreign currency exchange contracts, which are types of derivative contracts. A forward foreign currency exchange contract is an agreement to buy or sell a country’s currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. In other words, the contract guarantees an exchange rate on a given date. Managers of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in U.S. dollar/foreign currency exchange rates. These contracts, however, would not prevent the Fund’s securities from falling in value during foreign market downswings.

Vanguard typically invests a small portion of the Fund’s assets in stock index futures and/or shares of exchange-traded funds (ETFs), including ETF Shares issued by Vanguard stock funds. Stock index futures and ETFs provide returns similar to those of common stocks. Vanguard may purchase futures or ETFs when doing so will reduce the Fund’s transaction costs or add value because the instruments are favorably priced. Vanguard receives no additional revenue from investing Fund assets in ETF Shares of other Vanguard funds. Fund assets invested in ETF Shares are excluded when allocating to the Fund its share of the costs of Vanguard operations.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds. When investing in a Vanguard CMT Fund, the Fund bears its proportionate share of the at-cost expenses of the CMT Fund in which it invests.

9

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when doing so is believed to be in the Fund’s best interest, so long as the alternative is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond the normal limits in derivatives or ETFs that are consistent with the Fund’s objective when those instruments are more favorably priced or provide needed liquidity, as might be the case when the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.

In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash, commercial paper, or other less volatile instruments—in response to adverse or unusual market, economic, political, or other conditions. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.

Redemption and Account Service Fees

The Fund charges a 1% fee on shares redeemed before they have been held for one year. The fee applies if you redeem shares by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because the balance falls below the minimum initial investment for any reason, including market fluctuation. Shares you have held the longest will be redeemed first.

Unlike a sales charge or a load paid to a broker or a fund management company, the redemption fee is paid directly to the Fund to offset the costs of buying and selling securities. The redemption fee is designed to ensure that short-term investors pay their share of the Fund’s transaction costs and that long-term investors do not subsidize the activities of short-term traders.

An account service fee of $20 per year applies to certain fund accounts whose balances are less than $10,000.

See the Fund Summary and Investing With Vanguard for more information about fees.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund’s shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, a fund

10

incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor’s ability to efficiently manage the fund.

Policies to Address Frequent Trading. The Vanguard funds (other than money market funds, short-term bond funds, and Vanguard ETF™ Shares) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

• Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected if Vanguard determines that such purchase may negatively affect a fund’s operation or performance or because of a history of frequent trading by the investor.

• Each Vanguard fund (other than money market funds, short-term bond funds, and ETF Shares) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account.

• Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

See the Investing With Vanguard section of this prospectus for further details on Vanguard’s transaction policies.

Each fund (other than money market funds), in determining its net asset value, will, when appropriate, use fair-value pricing, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund normally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. The average turnover rate for mid-cap value funds was approximately xx%, as reported by Morningstar, Inc., on October 31, 2009.

11

Plain Talk About Turnover Rate

Before investing in a mutual fund, you should review its turnover rate. This gives an indication of how transaction costs, which are not included in the fund’s expense ratio, could affect the fund’s future returns. In general, the greater the volume of buying and selling by the fund, the greater the impact that brokerage commissions and other transaction costs will have on its return. Also, funds with high turnover rates may be more likely to generate capital gains that must be distributed to shareholders as taxable income.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of 37 investment companies with more than 160 funds holding assets of approximately $x.x trillion. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, equipment, and advertising.

Vanguard also provides marketing services to the funds. Although shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of the fund (in the case of a fund with multiple share classes) pays its allocated share of The Vanguard Group’s marketing costs.

Plain Talk About Vanguard’s Unique Corporate Structure

The Vanguard Group is truly a mutual mutual fund company. It is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that may be owned by one person, by a private group of individuals, or by public investors who own the management company’s stock. The management fees charged by these companies include a profit component over and above the companies’ cost of providing services. By contrast, Vanguard provides services to its member funds on an at-cost basis, with no profit component, which helps to keep the funds’ expenses low.

Investment Advisors

The Fund uses a multimanager approach. Each advisor independently manages its assigned portion of the Fund’s assets, subject to the supervision and oversight of Vanguard and the Fund’s board of trustees. The board of trustees designates the

12

proportion of Fund assets to be managed by each advisor and may change these proportions at any time.

• Barrow, Hanley, Mewhinney & Strauss, Inc., 2200 Ross Avenue, 31st Floor, Dallas, TX 75201, is an investment advisory firm founded in 1979. Barrow, Hanley is a subsidiary of Old Mutual Asset Managers (US) LLC, which is a subsidiary of Old Mutual plc. As of October 31, 2009, the firm managed approximately $xx.x billion in assets.

• Donald Smith & Co., Inc., 152 West 57th Street, 22nd Floor, New York, NY 10019, is an investment advisory firm that was founded as Home Portfolio Advisors in 1975 and renamed Donald Smith & Co., Inc., in 1984. As of October 31, 2009, Donald Smith & Co. managed approximately $xx.x billion in assets.

The Fund pays each advisor on a quarterly basis. Each advisor receives a base fee that is based on certain annual percentage rates applied to average daily net assets managed by the advisor during the most recent fiscal quarter. The fee paid to each advisor may be increased or decreased based on the advisor’s performance compared with that of a benchmark index. For these purposes, the cumulative total return of the Barrow, Hanley portion of the Fund is compared with that of the Russell Midcap Value Index over a trailing 36-month period, and the cumulative total return of the Donald Smith & Co. portion of the Fund is compared with that of the Morgan Stanley Capital International US Investable Market 2500 Index over a trailing 60-month period. Please note that over time, changes in an advisor’s relative performance may result in changes in the performance-based fees paid by the Fund, which in turn would result in an increase or decrease in the expenses borne by Fund shareholders.

For the fiscal year ended October 31, 2009, the aggregate advisory fee represented an effective annual rate of 0.xx% of the Fund’s average net assets performance-based increase of 0.xx%.

Under the terms of an SEC exemption, the Fund’s board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement or hire a new investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund’s advisory arrangements will be communicated to shareholders in writing. In addition, as the Fund’s sponsor and overall manager, The Vanguard Group may provide investment advisory services to the Fund, on an at-cost basis, at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced, or that the terms of an existing advisory agreement be revised.

For a discussion of why the board of trustees approved the Fund’s investment advisory agrrements, see the most recent semiannual to shareholders covering the fiscal year ended April 30.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest and dividends, less expenses) as well as any net capital gains realized from the sale of its holdings. Distributions generally occur annually in December. You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund’s income from interest and dividends as well as capital gains from the fund’s sale of investments. Income consists of both the dividends that the fund earns from any stock holdings and the interest it receives from any money market and bond investments. Capital gains are realized whenever the fund sells securities for higher prices than it paid for them. These capital gains are either short-term or long-term, depending on whether the fund held the securities for one year or less or for more than one year.

14

Basic Tax Points

Vanguard will send you a statement each year showing the tax status of all your distributions. In addition, investors in taxable accounts should be aware of the following basic federal income tax points:

• Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

• Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

• Any dividend and short-term capital gains distributions that you receive are taxable to you as ordinary income. If you are an individual and meet certain holding-period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on “qualified dividend income,”if any, distributed by the Fund.

• Any distributions of net long-term capital gains are taxable to you as long-term capital gains, no matter how long you’ve owned shares in the Fund.

• Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

• A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

This prospectus provides general tax information only. If you are investing through a tax-deferred retirement account, such as an IRA, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About ‘Buying a Dividend’

Unless you are investing through a tax-deferred retirement account (such as an IRA), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as “buying a dividend.” For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid “buying a dividend,” check a fund’s distribution schedule before you invest.

General Information

Backup withholding. By law, Vanguard must withhold 28% of any taxable distributions or redemptions from your account if you do not:

• Provide us with your correct taxpayer identification number;

• Certify that the taxpayer identification number is correct; and

• Confirm that you are not subject to backup withholding.

Similarly, Vanguard must withhold taxes from your account if the IRS instructs us to do so.

Foreign investors. Vanguard funds generally are not sold outside the United States, except to certain qualified investors. If you reside outside the United States, please consult our website at www.vanguard.com and review “Non-U.S. investors.” Foreign investors should be aware that U.S. withholding and estate taxes may apply to any investments in Vanguard funds.

Invalid addresses. If a dividend or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest all future distributions until you provide us with a valid mailing address.

Share Price

Share price, also known as net asset value (NAV), is calculated each business day as of the close of regular trading on the New York Stock Exchange, generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not transact purchase or redemption requests. However, on those days the value of the Fund’s assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open.

Stocks held by a Vanguard fund are valued at their market value when reliable market quotations are readily available. Certain short-term debt instruments used to manage a fund’s cash are valued on the basis of amortized cost. The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party. The values of any mutual fund shares held by a fund are based on the NAVs of the shares. The values of any ETF or closed-end fund shares held by a fund are based on the market value of the shares.

When a fund determines that market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security). A fund also will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the fund’s pricing time but after

16

the close of the primary markets or exchanges on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges that close many hours before the fund’s pricing time. Intervening events might be company-specific (e.g., earnings report, merger announcement); country-specific (e.g., natural disaster, economic or political news, act of terrorism, interest rate change); or global. Intervening events include price movements in U.S. markets that are deemed to affect the value of foreign securities. Fair-value pricing may be used for domestic securities—for example, if (1) trading in a security is halted and does not resume before the fund’s pricing time or if a security does not trade in the course of a day, and (2) the fund holds enough of the security that its price could affect the NAV.

Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Vanguard fund share prices are published daily on our website at www.vanguard.com/prices.

Financial Highlights

The following financial highlights table is intended to help you understand the Fund's financial performance for the periods shown, and certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned or lost each period on an investment in the Fund (assuming reinvestment of all distributions). This information has been derived from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report—along with the Fund’s financial statements—is included in the Fund’s most recent annual report to shareholders. You may obtain a free copy of the latest annual or semiannual report online at www.vanguard.com or by contacting Vanguard by telephone or mail.

Plain Talk About How to Read the Financial Highlights Table

The Fund began fiscal year 2009 with a net asset value (price) of $xx.xx per share. During the year, the Fund earned $xx.xx per share from investment income (interest and dividends) and $xx.xx per share from investments that had appreciated in value or that were sold for higher prices than the Fund paid for them.

Shareholders received $xx.xx per share in the form of dividend and capital gains distributions. A portion of each year’s distributions may come from the prior year’s income or capital gains.

The share price at the end of the year was $xx.xx, reflecting earnings of $xx.xx per share and distributions of $xx.xx per share. This was an increase of $xx.xx per share (from $xx.xx at the beginning of the year to $xx.xx at the end of the year). For a shareholder who reinvested the distributions in the purchase of more shares, the total return was xx% for the year.

As of October 31, 2009, the Fund had approximately $xxx billion in net assets. For the year, the expense ratio was x.xx% ($x.xx per $1,000 of net assets), and the net investment income amounted to xx% of its average net assets. The Fund sold and replaced securities valued at xx% of its net assets.

18

1 Calculated based on average shares outstanding.

2 Total returns do not reflect the 1% fee assessed on redemptions after March 23, 2005, of shares held for less than one year; the 1% fee assessed until March 23, 2005, on shares purchased on or after August 7, 2001, and held for less than five years; or the account service fee that may be applicable to certain accounts with balances below $10,000.

3 Includes performance-based investment advisory fee increases (decreases) of (x.xx%), (0.03%), (0.02%), (0.05%), and (0.02%).

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Be sure to carefully read each topic that pertains to your relationship with Vanguard. Vanguard reserves the right to change the following policies, without notice to shareholders. Please call or check online for current information.

Each fund you hold in an account is a separate “fund account.” For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open or maintain a fund account, or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

Account Minimums for Investor Shares To open and maintain an account. $25,000.

Add to an existing account. $100 by check, exchange, wire, or electronic bank transfer (other than Automatic Investment Plan, which has no established minimum).

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limits, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange (the purchase of shares of one Vanguard fund using the proceeds of a simultaneous redemption from another Vanguard fund) through our website at www.vanguard.com if you are a registered user.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from your account statement), with a deposit slip (available online), or with a written request. You may also send a written request to Vanguard to make an exchange. For a list of Vanguard addresses, see Contacting Vanguard.

20

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer option on an account, you must designate the bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or from time to time. Your purchase request can be initiated online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may send a check to make initial or additional purchases to your fund account. Also see How to Initiate a Purchase Request: By mail. Make your check payable to Vanguard and include the appropriate fund number (Vanguard—811).

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the New York Stock Exchange (NYSE) is open for regular trading (a business day).

For purchases by check into all funds other than money market funds, and for purchases by exchange or wire into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market

21

mutual fund one business day to convert check proceeds into federal funds, the trade date will be one business day later than for other funds.

For purchases by electronic bank transfer using an Automatic Investment Plan: Your trade date generally will be one business day before the date you designated for withdrawal from your bank account.

For purchases by electronic bank transfer not using an Automatic Investment Plan: If the purchase request is received by Vanguard on a business day before 10 p.m., Eastern time, the trade date generally will be the next business day. If the purchase request is received on a business day after 10 p.m., Eastern time, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the request.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

Other Purchase Rules You Should Know

Check purchases. All purchase checks must be written in U.S. dollars and must be drawn on a U.S. bank. Vanguard does not accept cash, traveler’s checks, or money orders. In addition, Vanguard may refuse “starter checks” and checks that are not made payable to Vanguard.

New accounts. We are required by law to obtain from you certain personal information that we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your identity, Vanguard reserves the right, without notice, to close your account or take such other steps as we deem reasonable.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because of a history of frequent trading by the investor or because the purchase may negatively affect a fund’s operation or performance.

Large purchases. Please call Vanguard before attempting to invest a large dollar amount.

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

22

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limits, and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares and request an exchange (using the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund) through our website at www.vanguard.com if you are a registered user.

By telephone. You may call Vanguard to request a redemption of shares. See

Contacting Vanguard.

By mail. You may send a written request to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard.

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer option on an account, you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or from time to time. Your redemption request can be initiated online, by telephone, or by mail.

By wire. When redeeming from a money market fund or a bond fund, you may instruct Vanguard to wire your redemption proceeds ($1,000 minimum) to a previously designated bank account. Wire redemptions generally are not available for Vanguard’s balanced or stock funds. The wire redemption option is not automatic; you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form.

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are

23

redeeming. Your redemption will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the NYSE is open for regular trading (a business day).

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

• Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

• Note on timing of wire redemptions from bond funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer using an Automatic Withdrawal Plan: Your trade date generally will be the date you designated for withdrawal of funds (redemption of shares) from your Vanguard account. Proceeds of redeemed shares generally will be credited to your designated bank account two business days after your trade date. If the date you designated for withdrawal of funds from your Vanguard account falls on a weekend, holiday, or other nonbusiness day, your trade date will be the previous business day.

For redemptions by electronic bank transfer not using an Automatic Withdrawal Plan: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to

24

complete your transaction. If Vanguard is still unable to complete the transaction, we may use your proceeds to purchase new shares of the Fund in which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

For further information about redemption transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

Redemption Fee

The Fund charges a 1% fee on shares redeemed before they have been held for one year. The fee applies if you redeem shares by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because that balance falls below the minimum initial investment for any reason, including market fluctuation. The fee is withheld from redemption proceeds and is paid directly to the Fund. Shares held for one year or more are not subject to the 1% fee.

In an effort to reduce or eliminate the redemption fees you pay, if you redeem less than your full investment in the Fund, we will first redeem those shares not subject to the fee, followed by those shares you have held the longest.

Redemption fees will not apply to Vanguard fund account redemptions in the following circumstances: (1) redemptions of shares purchased with reinvested dividend and capital gains distributions; redemptions of shares to pay fund or account fees; redemptions of shares to revoke an IRA within the period of time set forth in the Vanguard Traditional and Roth IRA Disclosure Document or to remove excess shareholder contributions to an IRA; and redemptions from Section 529 college savings plans; (2) share transfers, rollovers, or reregistrations within the same fund; (3) conversions of shares from one share class to another in the same fund; and (4) for a one-year period, shares rolled over to an IRA held at Vanguard from a retirement plan for which Vanguard serves as recordkeeper.*

In addition, redemption fees will not apply to (1) distributions by shareholders age 70½ or older from traditional IRAs, rollover IRAs, SEP-IRAs, SIMPLE IRAs, certain Individual Section 403(b)(7) Custodial Accounts, and Vanguard Retirement Plans and Vanguard Individual 401(k) Plans for which Vanguard Fiduciary Trust Company serves as trustee; and (2) distributions by beneficiaries from inherited IRAs, certain Individual Section 403(b)(7) Custodial Accounts, and Vanguard Retirement Plans and Vanguard Individual 401(k) Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Also, participants in employer-sponsored defined contribution plans* will not incur redemption fees for the following: exchanges of shares purchased with participant payroll or employer contributions; distributions, loans, and in-service withdrawals from a plan, redemptions or transfers of shares as part of a plan termination or at the direction of the plan; and direct rollovers into IRAs.

25

Participants will incur redemption fees if, after making an exchange, transfer, or rollover into a fund with a redemption fee, the participant makes a subsequent exchange out of that fund within the redemption-fee period.

If Vanguard does not serve as recordkeeper for your plan, redemption fees may be applied differently. Please read your recordkeeper’s plan materials carefully to learn of any other rules or fees that may apply. Also see Frequent-Trading Limits—Accounts Held by Intermediaries for information about the assessment of redemption fees by intermediaries.

* The following Vanguard fund accounts will be subject to redemption fees: SEP-IRAs, SIMPLE IRAs, certain Section 403(b)(7) accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund’s operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limits for information about Vanguard’s policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to ten calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Share certificates. If you hold shares in certificates, those shares cannot be redeemed or exchanged until you return the certificates (unsigned) to Vanguard by registered mail. For the correct address, see Contacting Vanguard.

Address change. If you change your address online or by telephone, there may be a 15-day restriction on your ability to request redemptions online and by telephone. You

26

can request a redemption in writing at any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require a signature guarantee. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange. A notary public cannot provide a signature guarantee.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason.

Frequent-Trading Limits

Because excessive transactions can disrupt management of a fund and increase the fund’s costs for all shareholders, Vanguard places certain limits on frequent trading in the Vanguard funds. Each Vanguard fund (other than money market funds and short-term bond funds) limits an investor’s purchases or exchanges into a fund account for

27

60 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to the frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the policy applies to exchanges made online or by phone.

The frequent-trading policy does not apply to the following:

• Purchases of shares with reinvested dividend or capital gains distributions.

• Transactions through Vanguard’s Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online^®.

• Redemptions of shares to pay fund or account fees.

• Transaction requests submitted by mail to Vanguard from shareholders who hold their accounts directly with Vanguard. (Transaction requests submitted by fax, if otherwise permitted, are not mail transactions and are subject to the policy.)

• Transfers and reregistrations of shares within the same fund.

• Purchases of shares by asset transfer or direct rollover.

• Conversions of shares from one share class to another in the same fund.

• Checkwriting redemptions.

• Section 529 college savings plans.

• Certain approved institutional portfolios and asset allocation programs, as well as trades made by Vanguard funds that invest in other Vanguard funds. (Please note that shareholders of Vanguard’s funds of funds are subject to the policy.)

For participants in employer-sponsored defined contribution plans,* the frequent-trading policy does not apply to:

• Purchases of shares with participant payroll or employer contributions or loan repayments.

• Purchases of shares with reinvested dividend or capital gains distributions.

• Distributions, loans, and in-service withdrawals from a plan.

• Redemptions of shares as part of a plan termination or at the direction of the plan.

• Automated transactions executed during the first six months of a participant’s enrollment in the Vanguard Managed Account Program.

• Redemptions of shares to pay fund or account fees.

• Share or asset transfers or rollovers.

• Reregistrations of shares.

• Conversions of shares from one share class to another in the same fund.

28

• Exchange requests submitted by mail to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are not mail requests and are subject to the policy.)

* The following Vanguard fund accounts are subject to the frequent-trading policy: SEP-IRAs, SIMPLE IRAs, certain Section 403(b)(7) accounts, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients’ accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client’s accounts the 60-day policy previously described, prohibiting a client’s purchases of fund shares, and/or revoking the client’s exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary’s clients. Intermediaries also may monitor their clients’ trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase or redemption fees, intermediaries will be asked to assess purchase and redemption fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent-trading policies may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading policies. If you invest with Vanguard through an intermediary, please read that firm’s materials carefully to learn of any other rules or fees that may apply.

Please see Frequent-Trading Limits—Accounts Held by Intermediaries for information about the assessment of redemption fees and monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

For most shareholders, Vanguard charges a $20 account service fee on all fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement fund accounts and will be assessed on fund accounts in all Vanguard funds, regardless of a fund’s minimum investment amount. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from a fund account only once per calendar year.

If you register on Vanguard.com and elect to receive electronic delivery of statements, reports, and other materials for all of your fund accounts, the account service fee for balances below $10,000 will not be charged, so long as that election remains in effect.

The account service fee also does not apply to the following:

• Money market sweep accounts owned in connection with a Vanguard Brokerage Services^® account.

• Accounts held through intermediaries.

• Accounts held by Voyager, Voyager Select, and Flagship members. Membership is based on total household assets held at Vanguard, with a minimum of $100,000 to qualify for Vanguard Voyager Services^®, $500,000 for Vanguard Voyager Select Services^®, and $1 million for Vanguard Flagship Services^®. Vanguard determines membership by aggregating assets of all eligible accounts held by the investor and immediate family members who reside at the same address. Aggregate assets include investments in Vanguard mutual funds, Vanguard ETFs™, annuities through Vanguard, the Vanguard 529 Plan, certain small-business accounts, and employer-sponsored retirement plans for which Vanguard provides recordkeeping services.

• Participant accounts in employer-sponsored defined contribution plans.* Please consult your enrollment materials for the rules that apply to your account.

• Section 529 college savings plans.

* The following Vanguard fund accounts have alternative fee structures: SIMPLE IRAs, certain Section 403(b)(7) accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

32

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the minimum initial investment for any reason, including market fluctuation. This policy applies to nonretirement fund accounts and accounts that are held through intermediaries. Shares redeemed in accordance with this policy will be subject to applicable redemption fees.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time; (2) accept initial purchases by telephone; (3) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners, or if we reasonably believe a fraudulent transaction may occur or has occurred; (4) temporarily freeze any account and/or suspend account services upon initial notification to Vanguard of the death of the shareholder until Vanguard receives required documentation in good order; (5) alter, impose, discontinue, or waive any redemption fee, account service fee, or other fees charged to a group of shareholders; and (6) redeem an account or suspend account privileges, without the owner’s permission to do so, in cases of threatening conduct or activity Vanguard believes to be suspicious, fraudulent, or illegal. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, we reasonably believe they are deemed to be in the best interest of a fund.

Fund Summary

Investment Objective

The Fund seeks to provide long-term capital appreciation.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy and hold shares of the Fund.

1 The 2% fee applies only if you redeem shares within two months of purchase by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because the balance falls below the minimum initial investment for any reason, including market fluctuation.

Example

The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. They illustrate the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. The first example assumes that the Fund provides a return of 5% a year, that operating expenses remain the same, and that you redeem your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was xx% of the average value of its portfolio.

Primary Investment Strategies

The Fund invests primarily in the equity securities of small-capitalization companies located outside the United States that the advisor believes offer the potential for capital appreciation. In doing so, the advisor considers, among other things, whether a company is likely to have above-average earnings growth, whether the company’s securities are attractively valued, and whether the company has any proprietary advantages.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund’s performance could be hurt by:

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, investments in foreign stock markets can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions.

• Investment style risk, which is the chance that returns from non-U.S. small-capitalization growth stocks will trail returns from the overall stock market. Historically, non-U.S. small-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.

• Currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

• Country/regional risk, which is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries or regions. Because the Fund may

2

invest a large portion of its assets in securities of companies located in any one country or region, including emerging markets, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in that area. Country/ regional risk is especially in emerging markets

• Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Fund compare with those of a relevant market index. The Standard & Poor’s Europe and Pacific (S&P EPAC) Small Cap Index measures the performance of the smallest companies from the 24 European and Pacific countries represented in the S&P Broad Market Index. The Index represents companies whose assets place them among the bottom 15% of the total market capital of each country. (Prior to October 31, 2008, the Index was known as the S&P/ Citigroup Extended Market Europe and Pacific Index.) Since April 1, 2007, the Index returns are adjusted for withholding taxes applicable to the Luxembourg holding companies. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at www.vanguard.com/performance or by calling Vanguard toll-free at 800-662-7447.

Annual Total Returns—Investor Shares

NO CHART DATA

During the periods shown in the bar chart, the highest return for a calendar quarter was XX.XX% (quarter ended xxxx), and the lowest return for a quarter was XX.XX% (quarter ended xxxx).

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

Tax Information

The Fund’s distributions may be taxable as ordinary income or capital gains. Distributions are taxable to you for federal income tax purposes, whether or not you reinvest these amounts in additional Fund shares. A sale or exchange of Fund shares is a taxable event, which means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your federal income tax return. Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may also be subject to state and local income taxes.

Financial Intermediary Compensation

The Fund and its investment advisor do not pay financial intermediaries for sales of Fund shares or related services.

More on the Fund

This prospectus describes the primary risks you would face as a Fund shareholder. It is important to keep in mind one of the main axioms of investing: The higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: The lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk^® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

The following sections explain the primary investment strategies and policies that the Fund uses in pursuit of its objective. The Fund’s board of trustees, which oversees the Fund’s management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are

5

designated as fundamental. Note that the Fund’s investment objective is not fundamental and may be changed without a shareholder vote. <BLANK

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted from a fund’s gross income, are expressed as a percentage of the net assets of the fund. Vanguard International Explorer Fund’s expense ratio in fiscal year 2009 was X.XX%, or $X.XX per $1,000 of average net assets. The average expenses for international small-cap funds in 2008 were X.XX%, or $X.XX per $1,000 of average net assets (derived from data provided by Lipper Inc., which reports on the mutual fund industry). Management expenses, which are one part of operating expenses, include investment advisory fees as well as other costs of managing a fund—such as account maintenance, reporting, accounting, legal, and other administrative expenses.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That’s because you, as a shareholder, pay the costs of operating a fund, plus any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund’s performance.

Market Exposure

The Fund invests primarily in the equity securities of smaller companies located outside the United States.

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund’s investments in foreign stock markets can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions. In addition, the Fund’s target index may, at times, become focused in stocks of a particular sector, category, or group of companies.

To illustrate the volatility of international stock prices, the following table shows the best, worst, and average annual total returns for foreign stock markets over various periods as measured by the MSCI EAFE Index, a widely used barometer of international market activity. (Total returns consist of dividend income plus change in

6

market price.) Note that the returns shown do not include the costs of buying and selling stocks or other expenses that a real-world investment portfolio would incur.

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1970 through 2008. These average returns reflect past performance of international stocks; you should not regard them as an indication of future performance of either foreign markets as a whole or the Fund in particular.

Note that the MSCI EAFE Index does not take into account returns for emerging markets, which can be substantially more volatile, and substantially less liquid, than the more developed markets included in the Index. In addition, because the MSCI EAFE Index tracks the European and Pacific developed markets collectively, the returns in the preceding table do not reflect the variability of returns for these markets individually. To illustrate this variability, the following table shows returns for different international markets—as well as for the U.S. market for comparison—from 1999 through 2008, as measured by their respective indexes.

7

1 European market returns are measured by the MSCI Europe Index; Pacific market returns are measured by the MSCI Pacific Index; emerging markets returns are measured by the MSCI Emerging Markets Index; and U.S. market returns are measured by the Standard & Poor‘s 500 Index.

2 Index returns are adjusted for withholding taxes applicable to Luxembourg holding companies.

Keep in mind that these returns reflect past performance of the various indexes; you should not consider them as an indication of future performance of the indexes, or of the Fund in particular.

Plain Talk About International Investing

U.S. investors who invest abroad will encounter risks not typically associated with U.S. companies, because foreign stock and bond markets operate differently from the U.S. markets. For instance, foreign companies are not subject to the same accounting, auditing, and financial-reporting standards and practices as U.S. companies, and their stocks may not be as liquid as those of similar U.S. firms. In addition, foreign stock exchanges, brokers, and companies generally have less government supervision and regulation than their counterparts in the United States. These factors, among others, could negatively affect the returns U.S. investors receive from foreign investments.

8

The Fund is subject to country/regional risk and currency risk. Country/regional risk is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries or regions. Because the Fund may invest a large portion of its assets in securities of companies located in any one country or region, its performance may be hurt disproportionately by the poor performance of its investments in that area. Country/regional risk is especially high in emerging markets. Currency risk is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

The Fund generally emphasizes developed markets in Europe and the Pacific, with a limited allocation to emerging markets. Stocks of emerging-market countries can be substantially more volatile, and substantially less liquid, than those of both U.S. and more developed foreign markets.

The Fund is subject to investment style risk, which is the chance that returns from non-U.S. small-capitalization growth stocks will trail returns from the overall stock market. Historically, non-U.S. small-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.

Stocks of publicly traded companies and funds that invest in stocks are often classified according to market value, or market capitalization. These classifications typically include small-cap, mid-cap, and large-cap. It’s important to understand that, for both companies and stock funds, market-capitalization ranges change over time. Also, interpretations of size vary, and there are no “official” definitions of small-, mid-, and large-cap, even among Vanguard fund advisors. The asset-weighted median market capitalization of the Fund as of October 31, 2009, was xx% billion.

The Fund invests in companies that are smaller and less well-known than larger, more widely held companies. Small companies tend to be more vulnerable to adverse developments than larger companies. Small companies may have limited product lines, markets, or financial resources, or they may depend on a limited management group. Their securities may trade infrequently and in limited volumes. As a result, the prices of these securities may fluctuate more than the prices of securities of larger, more widely traded companies. Also, there may be less publicly available information about small companies or less market interest in their securities as compared with larger companies, and it may take longer for the prices of these securities to reflect the full value of their issuers’ earnings potential or assets.

9

Security Selection

Schroder Investment Management North America Inc. (Schroders), advisor to the Fund, employs a fundamental investment approach that considers macroeconomic factors while focusing primarily on company-specific factors. These company-specific factors include the company’s potential for long-term growth, financial condition, quality of management, and sensitivity to cyclical factors, as well as the relative value of the company’s securities (compared with those of other companies and the market as a whole).

The advisor invests the Fund’s assets in non-U.S. small-cap companies that it believes offer the potential for capital appreciation. In doing so, Schroders considers, among other things, whether a company is likely to have above-average earnings growth, whether its securities are attractively valued, and whether the company has any proprietary advantages. The Fund generally sells a security when its market price approaches the advisor’s estimate of fair value or when the advisor identifies a significantly more attractive investment candidate.

The Fund is generally managed without regard to tax ramifications.

The Fund is subject to manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

Plain Talk About Growth Funds and Value Funds

Growth investing and value investing are two styles employed by stock-fund managers. Growth funds generally focus on stocks of companies believed to have above-average potential for growth in revenue, earnings, cash flow, or other similar criteria. These stocks typically have low dividend yields and above-average prices in relation to such measures as earnings and book value. Value funds typically emphasize stocks whose prices are below average in relation to those measures; these stocks often have above-average dividend yields. Growth and value stocks have historically produced similar long-term returns, though each category has periods when it outperforms the other.

Other Investment Policies and Risks

Besides investing in stocks of foreign companies, the Fund may make other kinds of investments to achieve its objective.

The Fund may invest in preferred stocks and closed-end investment companies that invest primarily in foreign securities. With preferred stocks, holders receive set dividends from the issuer; their claim on the issuer’s income and assets ranks before

10

that of common-stock holders, but after that of bondholders. The Fund may also invest in convertible securities and warrants. Convertible securities are corporate debt securities that may be converted at either a stated price or a stated rate into underlying shares of common stock. Warrants are securities that permit their owners to purchase a specific number of stock shares at a predetermined price in the future.

The Fund may invest, to a limited extent, in derivatives. Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, bond, or currency), a physical asset (such as gold), or a market index (such as the S&P 500 Index). Investments in derivatives may subject the Fund to risks different from, and possibly greater than, those of the underlying securities, assets, or market indexes. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

The Fund may enter into forward foreign currency exchange contracts, which are types of derivative contracts. A forward foreign currency exchange contract is an agreement to buy or sell a country’s currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. In other words, the contract guarantees an exchange rate on a given date. Managers of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in U.S. dollar/foreign currency exchange rates. These contracts, however, would not prevent the Fund’s securities from falling in value during foreign market downswings.

Plain Talk About Derivatives

Derivatives can take many forms. Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indexes, have been trading on regulated exchanges for decades. These types of derivatives are standardized contracts that can easily be bought and sold, and whose market values are determined and published daily. Nonstandardized derivatives (such as swap agreements), on the other hand, tend to be more specialized or complex, and may be harder to value.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds. When investing in a Vanguard CMT Fund, the Fund bears its proportionate share of the at-cost expenses of the CMT Fund in which it invests.

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when doing so is believed to be in the Fund’s best interest, so long as the alternative

11

is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond the normal limits in derivatives or ETFs that are consistent with the Fund’s objective when those instruments are more favorably priced or provide needed liquidity, as might be the case when the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.

In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash, commercial paper, or other less volatile instruments—in response to adverse or unusual market, economic, political, or other conditions. In doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.

Redemption and Account Service Fees

The Fund charges a 2% fee on shares redeemed before they have been held for two months. The fee applies if you redeem shares by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because the balance falls below the minimum initial investment for any reason, including market fluctuation. Shares you have held the longest will be redeemed first.

Unlike a sales charge or a load paid to a broker or a fund management company, the redemption fee is paid directly to the Fund to offset the costs of buying and selling securities. The redemption fee is designed to ensure that short-term investors pay their share of the Fund’s transaction costs and that long-term investors do not subsidize the activities of short-term traders.

An account service fee of $20 per year applies to certain fund accounts whose balances are less than $10,000.

See the Fund Summary and Investing With Vanguard for more information about fees.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund’s shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, a fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the

12

long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor’s ability to efficiently manage the fund.

Policies to Address Frequent Trading. The Vanguard funds (other than money market funds, short-term bond funds, and Vanguard ETF™ Shares) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

• Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected if Vanguard determines that such purchase may negatively affect a fund’s operation or performance or because of a history of frequent trading by the investor.

• Each Vanguard fund (other than money market funds, short-term bond funds, and ETF Shares) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account.

• Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

See the Investing With Vanguard section of this prospectus for further details on Vanguard’s transaction policies.

Each fund (other than money market funds), in determining its net asset value, will, when appropriate, use fair-value pricing, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund normally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. The average turnover rate for international stock funds was approximately xx%, as reported by Morningstar, Inc., on October 31, 2009.

Plain Talk About Turnover Rate

Before investing in a mutual fund, you should review its turnover rate. This gives an indication of how transaction costs, which are not included in the fund’s expense ratio, could affect the fund’s future returns. In general, the greater the volume of buying and selling by the fund, the greater the impact that brokerage commissions and other transaction costs will have on its return. Also, funds with high turnover rates may be more likely to generate capital gains that must be distributed to shareholdersas taxable income.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of 37 investment companies with more than 160 funds holding assets of approximately $xxx trillion. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, equipment, and advertising.

Vanguard also provides marketing services to the funds. Although shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of the fund (in the case of a fund with multiple share classes) pays its allocated share of The Vanguard Group’s marketing costs.

Plain Talk About Vanguard’s Unique Corporate Structure

The Vanguard Group is truly a mutual mutual fund company. It is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that may be owned by one person, by a private group of individuals, or by public investors who own the management company’s stock. The management fees charged by these companies include a profit component over and above the companies’ cost of providing services. By contrast, Vanguard provides services to its member funds on an at-cost basis, with no profit component, which helps to keep the funds’ expenses low.

Investment Advisors

• Schroder Investment Management North America Inc. (Schroders), 875 Third Avenue, 22nd Floor, New York, NY 10022-6225, has been a registered investment advisor, together with its predecessor, since 1968, and is part of a worldwide group of financial services companies known as The Schroder Group. Schroders currently

14

serves as investment advisor to the Fund, other mutual funds, and a broad range of institutional investors. As of October 31, 2009, Schroders, together with its affiliated companies, managed approximately $xxx billion in assets. Schroder Investment Management North America Ltd. (Schroder Limited), 31 Gresham Street, London, EC2V 7QA, England, has served as the sub-advisor for the Fund since April 1, 2003.

The Schroder International Smallcap Investment Committee is responsible for the management of the Fund. The Committee, composed of senior small-cap specialists, determines the country allocation of the Fund. Stock selection is primarily the responsibility of senior regional small-cap portfolio managers.

Schroders’ advisory fee is paid quarterly and is based on certain annual percentage rates applied to the Fund’s average daily net assets for each quarter. In addition, the firm’s advisory fee may be increased or decreased, based on the cumulative total return of the Fund over a trailing 36-month period as compared with that of the S&P/ Citigroup EM EPAC Index over the same period. Schroders pays 25% of its advisory fee to Schroder Limited for providing sub-advisory services.

For the fiscal year ended October 31, 2009, the aggregate advisory fee represented an effective annual rate of xxx% of the Fund’s average net assets based on a performance increase/decrease of x.xx%.

Under the terms of an SEC exemption, the Fund’s board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement or hire a new investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund’s advisory arrangements will be communicated to shareholders in writing. In addition, as the Fund’s sponsor and overall manager, The Vanguard Group may provide investment advisory services to the Fund, on an at-cost basis, at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced, or that the terms of an existing advisory agreement be revised.

For a discussion of why the board of trustees approved the Fund’s investment advisory agreement and sub-advisory agreement, see the most recent annual report to shareholders covering the fiscal year ended October 31.

The manager primarily responsible for the day-to-day management of the Fund is:

Matthew Dobbs, Chair of the Schroder International Smallcap Investment Committee and Portfolio Manager on the EAFE team. He has been with Schroders since 1981 and has managed the Fund since 2000. Education: B.A., Worcester College, Oxford University.

The Statement of Additional Information provides information about the portfolio manager’s compensation, other accounts under management, and ownership of shares of the Fund.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest and dividends, less expenses) as well as any net capital gains realized from the sale of its holdings. Distributions generally occur annually in December. <BLANK> You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund’s income from interest and dividends as well as capital gains from the fund’s sale of investments. Income consists of both the dividends that the fund earns from any stock holdings and the interest it receives from any money market and bond investments. Capital gains are realized whenever the fund sells securities for higher prices than it paid for them. These capital gains are either short-term or long-term, depending on whether the fund held the securities for one year or less or for more than one year.

Basic Tax Points

Vanguard will send you a statement each year showing the tax status of all your distributions. In addition, investors in taxable accounts should be aware of the following basic federal income tax points:

• Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

• Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

• Any dividend and short-term capital gains distributions that you receive are taxable to you as ordinary income. If you are an individual and meet certain holding-period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on “qualified dividend income,”if any, distributed by the Fund.

• Any distributions of net long-term capital gains are taxable to you as long-term capital gains, no matter how long you’ve owned shares in the Fund.

• Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

• A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

16

• Any conversion between classes of shares of the same fund is a nontaxable event. By contrast, an exchange between classes of shares of different funds is a taxable event.

Dividend and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

The Fund may be subject to foreign taxes or foreign tax withholding on dividends, interest, and some capital gains that the Fund receives on foreign securities. You may qualify for an offsetting credit or deduction under U.S. tax laws for any amount designated as your portion of the Fund’s foreign tax obligations, provided that you meet certain requirements. See your tax advisor or IRS publications for more information.

This prospectus provides general tax information only. If you are investing through a tax-deferred retirement account, such as an IRA, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About ‘Buying a Dividend’

Unless you are investing through a tax-deferred retirement account (such as an IRA), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as “buying a dividend.” For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid “buying a dividend,” check a fund’s distribution schedule before you invest.

General Information

Backup withholding. By law, Vanguard must withhold 28% of any taxable distributions or redemptions from your account if you do not:

• Provide us with your correct taxpayer identification number;

• Certify that the taxpayer identification number is correct; and

• Confirm that you are not subject to backup withholding.

Similarly, Vanguard must withhold taxes from your account if the IRS instructs us to do so.

17

Foreign investors. Vanguard funds generally are not sold outside the United States, except to certain qualified investors. If you reside outside the United States, please consult our website at www.vanguard.com and review “Non-U.S. investors.” Foreign investors should be aware that U.S. withholding and estate taxes may apply to any investments in Vanguard funds.

Invalid addresses. If a dividend or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest all future distributions until you provide us with a valid mailing address.

Share Price

Share price, also known as net asset value (NAV), is calculated each business day as of the close of regular trading on the New York Stock Exchange, generally 4 p.m., Eastern time. Each share class has its own NAV, which is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding <BLANK>. On holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not transact purchase or redemption requests. However, on those days the value of the Fund’s assets may be affected to the extent that the Fund holds foreign securities that trade on foreign markets that are open.

Stocks held by a Vanguard fund are valued at their market value when reliable market quotations are readily available. Certain short-term debt instruments used to manage a fund’s cash are valued on the basis of amortized cost. The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party. The values of any mutual fund shares held by a fund are based on the NAVs of the shares. The values of any ETF or closed-end fund shares held by a fund are based on the market value of the shares.

When a fund determines that market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security). A fund also will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the fund’s pricing time but after the close of the primary markets or exchanges on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges that close many hours before the fund’s pricing time. Intervening events might be company-specific (e.g., earnings report, merger announcement); country-specific (e.g., natural disaster, economic or political news, act of terrorism, interest rate change); or global. Intervening events include price movements in U.S. markets that are deemed to affect the value of foreign securities. Fair-value pricing may be used for domestic securities—for example, if (1) trading in a security is halted and does not

18

resume before the fund’s pricing time or if a security does not trade in the course of a day, and (2) the fund holds enough of the security that its price could affect the NAV.

Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Vanguard fund share prices are published daily on our website at www.vanguard.com/prices.

Financial Highlights

The following financial highlights table is intended to help you understand the Fund’s financial performance for the periods shown, and certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned or lost each period on an investment in the Fund (assuming reinvestment of all distributions). This information has been derived from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report—along with the Fund’s financial statements—is included in the Fund’s most recent annual report to shareholders. You may obtain a free copy of the latest annual or semiannual report online at www.vanguard.com or by contacting Vanguard by telephone or mail.

Plain Talk About How to Read the Financial Highlights Table

The Fund began fiscal year 2009 with a net asset value (price) of $xx.xx per share. During the year, the Fund earned $xx.xx per share from investment income (interest and dividends) and $xx.xx per share from investments that had appreciated in value or that were sold for higher prices than the Fund paid for them.

Shareholders received $xx.xx per share in the form of dividend <BLANK>/and capital gains distributions. A portion of each year’s distributions may come from the prior year’s income or capital gains.

The share price at the end of the year was $xx.xx, reflecting earnings of $xx.xx per share and distributions of $xx.xx per share. This was an increase of $xx.xx per share (from $xx.xx at the beginning of the year to $xx.xx at the end of the year). For a shareholder who reinvested the distributions in the purchase of more shares, the total return was xx% for the year.

As of October 31, 2009, the Fund had approximately $xxx billion in net assets. For the year, the expense ratio was x.xx% ($x.xx per $1,000 of net assets), and the net investment income amounted to xx% of its average net assets. The Fund sold and replaced securities valued at xx% of its net assets.

20

1 Calculated based on average shares outstanding.

2 Total returns do not reflect the 2% fee assessed on redemptions of shares purchased on or after June 27, 2003, and held for less than two months.

3 Includes performance-based investment advisory fee increases (decreases) of x.xx%, (0.01%), 0.00%, 0.02%, and 0.02%.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Be sure to carefully read each topic that pertains to your relationship with Vanguard. Vanguard reserves the right to change the following policies, without notice to shareholders. Please call or check online for current information.

Each fund you hold in an account is a separate “fund account.” For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open or maintain a fund account, or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

Account Minimums

To open and maintain an account. $25,000 for regular accounts, IRAs, and custodial account for minors.

Add to an existing account. $100 by check, exchange, wire, or electronic bank transfer (other than Automatic Investment Plan, which has no established minimum).

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limits, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange (the purchase of shares of one Vanguard fund using the proceeds of a simultaneous redemption of shares of another Vanguard fund) through our website at www.vanguard.com if you are a registered user.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with

22

an Invest-by-Mail form (from your account statement), with a deposit slip (available online), or with a written request. You may also send a written request to Vanguard to make an exchange. For a list of Vanguard addresses, see Contacting Vanguard.

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer option on an account, you must designate the bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or from time to time. Your purchase request can be initiated online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may send a check to make initial or additional purchases to your fund account. Also see How to Initiate a Purchase Request: By mail. Make your check payable to Vanguard and include the appropriate fund number (e.g., Vanguard—xx). For a list of Fund numbers (for DETERMINE IN BL in this prospectus), see Additional Information.

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the New York Stock Exchange (NYSE) is open for regular trading (a business day).

For purchases by check into all funds other than money market funds, and for purchases by exchange or wire into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the next business day. If the

23

purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market mutual fund one business day to convert check proceeds into federal funds, the trade date will be one business day later than for other funds.

For purchases by electronic bank transfer using an Automatic Investment Plan: Your trade date generally will be one business day before the date you designated for withdrawal from your bank account.

For purchases by electronic bank transfer not using an Automatic Investment Plan: If the purchase request is received by Vanguard on a business day before 10 p.m., Eastern time, the trade date generally will be the next business day. If the purchase request is received on a business day after 10 p.m., Eastern time, or on a nonbusiness day, the trade date will be the second business day following the day Vanguard receives the request.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

By telephone. You may call Vanguard to request a redemption of shares. See

Contacting Vanguard.

By mail. You may send a written request to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard.

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer option on an account, you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form. After the option is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or from time to time. Your redemption request can be initiated online, by telephone, or by mail.

By wire. When redeeming from a money market fund or a bond fund, you may instruct Vanguard to wire your redemption proceeds ($1,000 minimum) to a previously designated bank account. Wire redemptions generally are not available for Vanguard’s balanced or stock funds. The wire redemption option is not automatic; you must designate a bank account online, complete a special form, or fill out the appropriate section of your account registration form.

25

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are a registered user of Vanguard.com), by telephone, or by mail.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are redeeming. Your redemption will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the NYSE is open for regular trading (a business day).

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

• Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

• Note on timing of wire redemptions from bond funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer using an Automatic Withdrawal Plan: Your trade date generally will be the date you designated for withdrawal of funds (redemption of shares) from your Vanguard account. Proceeds of redeemed shares generally will be credited to your designated bank account two business days after your trade date. If the date you designated for withdrawal of funds from your

26

Vanguard account falls on a weekend, holiday, or other nonbusiness day, your trade date will be the previous business day.

For redemptions by electronic bank transfer not using an Automatic Withdrawal Plan: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to complete your transaction. If Vanguard is still unable to complete the transaction, we may use your proceeds to purchase new shares of the Fund in which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

For further information about redemption transactions, consult our website at www.vanguard.com or see Contacting Vanguard.

Redemption Fee

The Fund charges a 2% fee on shares redeemed before they have been held for two months . The fee applies if you redeem shares by selling or by exchanging to another Vanguard fund, or if Vanguard liquidates your Fund account because the balance falls below the minimum intitial investment for any reason, including market fluctuations. The fee is withheld from redemption proceeds and is paid directly to the Fund. Shares held for two months or more are not subject to the 2% fee.

In an effort to reduce or eliminate the redemption fees you pay, if you redeem less than your full investment in the Fund, we will first redeem those shares not subject to the fee, followed by those shares you have held the longest.

Redemption fees will not apply to Vanguard fund account redemptions in the following circumstances: (1) redemptions of shares purchased with reinvested dividend and capital gains distributions; redemptions of shares to pay fund or account fees; redemptions of shares to revoke an IRA within the period of time set forth in the Vanguard Traditional and Roth IRA Disclosure Document or to remove excess shareholder contributions to an IRA; and redemptions from Section 529 college savings plans; (2) share transfers, rollovers, or reregistrations within the same fund; (3) conversions of shares from one share class to another in the same fund; and (4) for a one-year period, shares rolled over to an IRA held at Vanguard from a retirement plan for which Vanguard serves as recordkeeper.*

27

In addition, redemption fees will not apply to (1) distributions by shareholders age 70½ or older from traditional IRAs, rollover IRAs, SEP-IRAs, SIMPLE IRAs, certain Individual Section 403(b)(7) Custodial Accounts, and Vanguard Retirement Plans and Vanguard Individual 401(k) Plans for which Vanguard Fiduciary Trust Company serves as trustee; and (2) distributions by beneficiaries from inherited IRAs, certain Individual Section 403(b)(7) Custodial Accounts, and Vanguard Retirement Plans and Vanguard Individual 401(k) Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Also, participants in employer-sponsored defined contribution plans* will not incur redemption fees for the following: exchanges of shares purchased with participant payroll or employer contributions; distributions, loans, and in-service withdrawals from a plan, redemptions or transfers of shares as part of a plan termination or at the direction of the plan; and direct rollovers into IRAs.

Participants will incur redemption fees if, after making an exchange, transfer, or rollover into a fund with a redemption fee, the participant makes a subsequent exchange out of that fund within the redemption-fee period.

If Vanguard does not serve as recordkeeper for your plan, redemption fees may be applied differently. Please read your recordkeeper’s plan materials carefully to learn of any other rules or fees that may apply. Also see Frequent-Trading Limits—Accounts Held by Intermediaries for information about the assessment of redemption fees by intermediaries.

* The following Vanguard fund accounts will be subject to redemption fees: SEP-IRAs, SIMPLE IRAs, certain Section 403(b)(7) accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund’s operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limits for information about Vanguard’s policies to limit frequent trading.

28

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to ten calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Share certificates. If you hold shares in certificates, those shares cannot be redeemed, exchanged, or converted until you return the certificates (unsigned) to Vanguard by registered mail. For the correct address, see Contacting Vanguard.

Address change. If you change your address online or by telephone, there may be a 15-day restriction on your ability to request redemptions online and by telephone. You can request a redemption in writing at any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require a signature guarantee. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange. A notary public cannot provide a signature guarantee.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are a registered user of Vanguard.com), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

29

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason.

Frequent-Trading Limits

Because excessive transactions can disrupt management of a fund and increase the fund’s costs for all shareholders, Vanguard places certain limits on frequent trading in the Vanguard funds. Each Vanguard fund (other than money market funds and short-term bond funds) limits an investor’s purchases or exchanges into a fund account for 60 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to the frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the policy applies to exchanges made online or by phone.

The frequent-trading policy does not apply to the following:

• Purchases of shares with reinvested dividend or capital gains distributions.

• Transactions through Vanguard’s Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online^®.

• Redemptions of shares to pay fund or account fees.

• Transaction requests submitted by mail to Vanguard from shareholders who hold their accounts directly with Vanguard. (Transaction requests submitted by fax, if otherwise permitted, are not mail transactions and are subject to the policy.)

• Transfers and reregistrations of shares within the same fund.

• Purchases of shares by asset transfer or direct rollover.

• Conversions of shares from one share class to another in the same fund.

• Checkwriting redemptions.

• Section 529 college savings plans.

• Certain approved institutional portfolios and asset allocation programs, as well as trades made by Vanguard funds that invest in other Vanguard funds. (Please note that shareholders of Vanguard’s funds of funds are subject to the policy.)

For participants in employer-sponsored defined contribution plans,* the frequent-trading policy does not apply to:

• Purchases of shares with participant payroll or employer contributions or loan repayments.

• Purchases of shares with reinvested dividend or capital gains distributions.

• Distributions, loans, and in-service withdrawals from a plan.

30

• Redemptions of shares as part of a plan termination or at the direction of the plan.

• Automated transactions executed during the first six months of a participant’s enrollment in the Vanguard Managed Account Program.

• Redemptions of shares to pay fund or account fees.

• Share or asset transfers or rollovers.

• Reregistrations of shares.

• Conversions of shares from one share class to another in the same fund.

• Exchange requests submitted by mail to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are not mail requests and are subject to the policy.)

* The following Vanguard fund accounts are subject to the frequent-trading policy: SEP-IRAs, SIMPLE IRAs, certain Section 403(b)(7) accounts, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients’ accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client’s accounts the 60-day policy previously described, prohibiting a client’s purchases of fund shares, and/or revoking the client’s exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary’s clients. Intermediaries also may monitor their clients’ trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase or redemption fees, intermediaries will be asked to assess purchase and redemption fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent-trading policies may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading policies. If you invest with Vanguard through an intermediary, please read that firm’s materials carefully to learn of any other rules or fees that may apply.

Other Rules You Should Know

Prospectus and Shareholder Report Mailings

Vanguard attempts to eliminate the unnecessary expense of duplicate mailings by sending just one prospectus and/or report when two or more shareholders have the same last name and address. You may request individual prospectuses and reports by contacting our Client Services Department in writing, by telephone, or by e-mail.

Vanguard.com

Registration. If you are a registered user of Vanguard.com, you can use your personal computer to review your account holdings; to buy, sell, or exchange shares of most Vanguard funds; and to perform most other transactions. You must register for this service online.

Electronic delivery. Vanguard can deliver your account statements, transaction confirmations, and fund financial reports electronically. If you are a registered user of Vanguard.com, you can consent to the electronic delivery of these documents by logging on and changing your mailing preference under “Account Profile.” You can revoke your electronic consent at any time online, and we will begin to send paper copies of these documents within 30 days of receiving your revocation.

Telephone Transactions

Automatic. When we set up your account, we’ll automatically enable you to do business with us by telephone, unless you instruct us otherwise in writing.

Tele-Account^®. To conduct account transactions through Vanguard’s automated telephone service, you must first obtain a Personal Identification Number (PIN). Call Tele-Account at 800-662-6273 to obtain a PIN, and allow seven days after requesting the PIN before using this service.

Proof of a caller’s authority. We reserve the right to refuse a telephone request if the caller is unable to provide the requested information or if we reasonably believe that the caller is not an individual authorized to act on the account. Before we allow a caller to act on an account, we may request the following information:

• Authorization to act on the account (as the account owner or by legal documentation or other means).

• Account registration and address.

• Fund name and account number, if applicable.

• Other information relating to the caller, the account owner, or the account.

32

Good Order

We reserve the right to reject any transaction instructions that are not in “good order.” Good order generally means that your instructions include:

• The fund name and account number.

• The amount of the transaction (stated in dollars, shares, or percentage).

Written instructions also must include:

• Signatures of all registered owners.

• Signature guarantees, if required for the type of transaction. (Call Vanguard for specific signature-guarantee requirements.)

• Any supporting documentation that may be required.

The requirements vary among types of accounts and transactions.

Vanguard reserves the right, without notice, to revise the requirements for good order.

Future Trade-Date Requests

Vanguard does not accept requests to hold a purchase, conversion, redemption, or exchange transaction for a future date. All such requests will receive trade dates as previously described in Purchasing Shares, Converting Shares, and Redeeming Shares. Vanguard reserves the right to return future-dated purchase checks.

Accounts With More Than One Owner

If an account has more than one owner or authorized person, Vanguard will accept telephone or online instructions from any one owner or authorized person.

Responsibility for Fraud

Vanguard will not be responsible for any account losses because of fraud if we reasonably believe that the person transacting business on an account is authorized to do so. Please take precautions to protect yourself from fraud. Keep your account information private, and immediately review any account statements that we provide to you. It is important that you contact Vanguard immediately about any transactions or changes to your account that you believe to be unauthorized.

Uncashed Checks

Please cash your distribution or redemption checks promptly. Vanguard will not pay interest on uncashed checks.

33

Unusual Circumstances

If you experience difficulty contacting Vanguard online, by telephone, or by Tele-Account, you can send us your transaction request by regular or express mail. See

Contacting Vanguard for addresses.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, broker, or investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply.

Please see Frequent-Trading Limits—Accounts Held by Intermediaries for information about the assessment of redemption fees and monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

For most shareholders, Vanguard charges a $20 account service fee on all fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement fund accounts and will be assessed on fund accounts in all Vanguard funds, regardless of a fund’s minimum investment amount. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from a fund account only once per calendar year.

If you register on Vanguard.com and elect to receive electronic delivery of statements, reports, and other materials for all of your fund accounts, the account service fee for balances below $10,000 will not be charged, so long as that election remains in effect.

The account service fee also does not apply to the following:

• Money market sweep accounts owned in connection with a Vanguard Brokerage Services^® account.

• Accounts held through intermediaries.

• Accounts held by Voyager, Voyager Select, and Flagship members. Membership is based on total household assets held at Vanguard, with a minimum of $100,000 to qualify for Vanguard Voyager Services^®, $500,000 for Vanguard Voyager Select Services^®, and $1 million for Vanguard Flagship Services^®. Vanguard determines membership by aggregating assets of all eligible accounts held by the investor and immediate family members who reside at the same address. Aggregate assets include investments in Vanguard mutual funds, Vanguard ETFs™, annuities through Vanguard, the Vanguard 529 Plan, certain small-business accounts, and employer-sponsored retirement plans for which Vanguard provides recordkeeping services.

34

• Participant accounts in employer-sponsored defined contribution plans.* Please consult your enrollment materials for the rules that apply to your account.

• Section 529 college savings plans.

* The following Vanguard fund accounts have alternative fee structures: SIMPLE IRAs, certain Section 403(b)(7) accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Retirement Plans for which Vanguard Fiduciary Trust Company serves as trustee.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the minimum initial investment for any reason, including market fluctuation. This policy applies to nonretirement fund accounts and accounts that are held through intermediaries. Shares redeemed in accordance with this policy will be subject to applicable redemption fees.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, conversion, service, or privilege at any time; (2) accept initial purchases by telephone; (3) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners, or if we reasonably believe a fraudulent transaction may occur or has occurred; (4) temporarily freeze any account and/or suspend account services upon initial notification to Vanguard of the death of the shareholder until Vanguard receives required documentation in good order; (5) alter, impose, discontinue, or waive any redemption fee, account service fee, or other fees charged to a group of shareholders; and (6) redeem an account or suspend account privileges, without the owner’s permission to do so, in cases of threatening conduct or activity Vanguard believes to be suspicious, fraudulent, or illegal. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, we reasonably believe they are deemed to be in the best interest of a fund.

Share Classes

Vanguard reserves the right, without notice, to change the eligibility requirements of its share classes, including the types of clients who are eligible to purchase each share class.

Fund and Account Updates

Confirmation Statements

We will send (or provide online, whichever you prefer) a confirmation of your trade date and the amount of your transaction when you buy, sell, exchange, or convert shares. However, we will not send confirmations reflecting only checkwriting redemptions or the reinvestment of dividend or capital gains distributions. For any month in which you had a checkwriting redemption, a Checkwriting Activity Statement will be sent to you itemizing the checkwriting redemptions for that month. Promptly review each confirmation statement that we provide to you by mail or online. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on a confirmation statement, or Vanguard will consider the transaction properly processed.

We will send (or provide online, whichever you prefer) quarterly portfolio summaries to help you keep track of your accounts throughout the year. Each summary shows the market value of your account at the close of the statement period, as well as all distributions, purchases, redemptions, exchanges, transfers, and conversions for the current calendar year. Promptly review each summary that we provide to you by mail or online. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on the summary, or Vanguard will consider the transaction properly processed.

These statements, which are generally mailed in January, will report the previous year’s dividends, capital gains distributions, proceeds from the sale of shares from taxable accounts, and distributions from IRAs and other retirement plans. Registered users can view these statements online.

Average-Cost Review Statements

For most taxable accounts, average-cost review statements will accompany annual Forms 1099-B. These statements show the average cost of shares that you redeemed during the previous calendar year, using the average-cost single-category method, which is one of the methods established by the IRS.

Annual and Semiannual Reports

We will send (or provide online, whichever you prefer) financial reports about Vanguard International Explorer Fund twice a year, in June and December. These

36

comprehensive reports include overviews of the financial markets and provide the following specific Fund information:

• Performance assessments and comparisons with industry benchmarks.

• Reports from the advisor.

• Financial statements with listings of Fund holdings.

Portfolio Holdings

We generally post on our website at www.vanguard.com, in the Portfolio section of the Fund’s Portfolio & Management page, a detailed list of the securities held by the Fund, as of the end of the most recent calendar quarter. This list is generally updated within 30 days after the end of each calendar quarter. Vanguard may exclude any portion of these portfolio holdings from publication when deemed in the best interest of the Fund. We also generally post the ten largest stock portfolio holdings of the Fund and the percentage of the Fund’s total assets that each of these holdings represents, as of the end of the most recent calendar quarter. This list is generally updated within 15 calendar days after the end of each calendar quarter.

Vanguard High Dividend Yield Index Fund Prospectus

February 25, 2010

Investor Shares

Vanguard High Dividend Yield Index Fund Investor Shares (VHDYX)

This prospectus contains financial data for the Fund through the fiscal year ended October 31, 2009.

The Securities and Exchange Commission has not approved or disapproved these securities or passed upon the adequacy of this prospectus. Any representation to the contrary is a criminal offense.

Fund Summary

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of common stocks of companies that are characterized by high dividend yield.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy and hold shares of the Fund.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was xx% of the average value of its portfolio.

Primary Investment Strategies

The Fund employs a “passive management” —or indexing—investment approach designed to track the performance of the FTSE^® High Dividend Yield Index, which consists of common stocks of companies that pay dividends that generally are higher than average. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. The Fund’s performance could be hurt by:

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund’s target index may, at times, become focused in stocks of a particular sector, category, or group of companies. Because the Fund seeks to track its target index, the Fund may underperform the overall stock market.

• Investment style risk, which is the chance that returns from high dividend-paying stocks will trail returns from the overall stock market. Specific types of stocks tend to go through cycles of doing better—or worse—than the stock market in general. These periods have, in the past, lasted for as long as several years.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund's Investor Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Investor Share compare with those of the Fund's target index. Keep in mind that the Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available on our website at www.vanguard.com/ performance or by calling Vanguard toll-free at 800-662-7447.
