Fund Summary

Investment Objective

The Fund seeks to provide long-term capital appreciation.

Fees and Expenses

The following table describes the fees and expenses you may pay if you buy and hold Investor Shares or Admiral Shares of the Fund.


Shareholder Fees
(Fees paid directly from your investment)
	Investor Shares	Admiral Shares
Sales Charge (Load) Imposed on Purchases	None	None
Purchase Fee	None	None
Sales Charge (Load) Imposed on Reinvested Dividends	None	None
Redemption Fee	None	None
Account Service Fee (for certain fund account balances below	$20/year	$20/year
$10,000)

Annual Fund Operating Expenses
(Expenses that you pay each year as a percentage of the value of your investment)
	Investor Shares	Admiral Shares
Management Fees	0.49%	0.33%
12b-1 Distribution Fee	None	None
Other Expenses	0.03%	0.02%
Total Annual Fund Operating Expenses¹	0.52%	0.35%
1 The expense information shown in the table has been restated to reflect estimated amounts for the current fiscal year.

Examples

The following examples are intended to help you compare the cost of investing in the Fund’s Investor Shares or Admiral Shares 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. These examples assume that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. 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 Year	3 Years	5 Years	10 Years
Investor Shares	$53	$167	$291	$653
Admiral Shares	$36	$113	$197	$443

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 more 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 examples, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 65% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests mainly in the stocks of small companies. These companies tend to be unseasoned but are considered by the Fund’s advisors to have superior growth potential. Also, these companies often provide little or no dividend income. The Fund uses multiple investment advisors.

Principal 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 is subject to the following risks, which could affect the Fund’s performance:

• 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 small-capitalization growth stocks will trail returns from the overall stock market. Historically, 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. Small companies tend to have greater stock volatility because, among other things, these companies are more sensitive to changing economic conditions.

• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. In addition, significant investment in the information technology sector subjects the Fund to proportionately higher exposure to the risks of this sector.

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 share classes presented compare with those of a relevant market index, which has investment characteristics similar to those of the Fund. 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 vanguard.com/performance or by calling Vanguard toll-free at 800-662-7447.

Annual Total Returns — Vanguard Explorer Fund Investor Shares¹

1 The year-to-date return as of the most recent calendar quarter, which ended on June 30, 2014, was XX%.

During the periods shown in the bar chart, the highest return for a calendar quarter was 19.79% (quarter ended June 30, 2009), and the lowest return for a quarter was –26.16% (quarter ended December 31, 2008).


Average Annual Total Returns for Periods Ended December 31, 2013
	1 Year	5 Years	10 Years
Vanguard Explorer Fund Investor Shares
Return Before Taxes	44.36%	23.08%	9.20%
Return After Taxes on Distributions	40.58	22.29	8.30
Return After Taxes on Distributions and Sale of Fund Shares	27.32	18.95	7.42
Vanguard Explorer Fund Admiral Shares

Russell 2500 Growth Index
(reflects no deduction for fees, expenses, or taxes)	40.65%	24.03%	10.11%

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 shown only for the Investor Shares and may differ for each share class. 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 may 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.

More on the Fund

This prospectus describes the principal risks you would face as a Fund shareholder. It is important to keep in mind one of the main axioms of investing: generally, 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.

Share Class Overview

The Fund offers two separate classes of shares: Investor Shares and Admiral Shares.

Both share classes offered by the Fund have the same investment objective, strategies, and policies. However, different share classes have different expenses; as a result, their investment performances will differ.

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. Assuming that operating expenses remain as stated in the Fees and

Expenses section, Vanguard Explorer Fund’s expense ratios would be as follows:

for Investor Shares, 0.52%, or $5.20 per $1,000 of average net assets; for

Admiral Shares, 0.35%, or $3.50 per $1,000 of average net assets. The average

expense ratio for small-cap growth funds in 2013 was 1.42%, or $14.20 per

$1,000 of average net assets (derived from data provided by Lipper, a Thomson

Reuters Company, which reports on the mutual fund industry).

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is because

you, as a shareholder, pay a proportionate share of 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 principal 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 focuses on companies that are considered small-cap by the Fund’s advisors.

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 is 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’s stock holdings as of October 31, 2013, was $3.2 billion.

Small-cap stocks tend to have greater volatility than large-cap stocks because, among other things, smaller companies often have fewer customers, financial resources, and products than larger firms. Such characteristics can make small-cap companies more sensitive to changing economic conditions. In addition, these companies typically provide little or no dividend income.

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 U.S. 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.


U.S. Stock Market Returns
(1926–2013)
	1 Year	5 Years	10 Years	20 Years
Best	54.2%	28.6%	19.9%	17.8%
Worst	–43.1	–12.4	–1.4	3.1
Average	12.0	9.9	10.4	11.1

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1926 through 2013. You can see, for example, that although the average annual return on common stocks for all of the 5-year periods was 9.9%, average annual returns for individual 5-year periods ranged from –12.4% (from 1928 through 1932) to 28.6% (from 1995 through 1999). These average annual 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.

Keep in mind that the Fund focuses on the stocks of smaller companies. Historically, small-cap stocks have been more volatile than—and at times have performed quite differently from—the large-cap stocks of the S&P 500 Index. This volatility is the result of several factors, which may include (but is not limited to) less certain growth and dividend prospects for smaller companies, fewer financial reserves during adverse market conditions, less access to captial funding, and generally greater sensitivity to changes within the company.

The Fund is subject to investment style risk, which is the chance that returns from small-capitalization growth stocks will trail returns from the overall stock market. Historically, 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. Small companies tend to have greater stock volatility because, among other things, these 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 measures such 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

style 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.

Each advisor employs active investment management methods, which means that securities are bought and sold according to the advisor’s 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, in the view of the advisor, 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; however, each is committed to buying stocks of small companies that, in the advisor‘s opinion, have strong growth potential.

Wellington Management Company, LLP (Wellington Management), uses research and analysis of individual companies to select stocks that the advisor feels have exceptional growth potential relative to their valuations in the marketplace. Wellington Management considers each stock individually before purchase and continually monitors developments at these companies for comparison with the advisor’s expectations for growth. To help limit risk, the portfolio is broadly diversified both by number of stocks and by exposure to a range of industries.

Granahan Investment Management, Inc. (Granahan), groups securities into three categories as part of its selection process. The first category, “core growth,” emphasizes companies that have a well-known or established product or service and, as a result, have a proven record of growth and a strong market position. The second category, “pioneers,” is made up of companies that offer unique products or services, technologies that may lead to new products, or expansion into new markets. Granahan judges pioneer stocks based on their estimated growth potential compared with market value. The third category, “special situation,” includes companies that lack a record of strong growth but that, in Granahan’s view, are both undervalued in the market and likely to grow in the next few years. Core growth stocks generally make up 35% to 70% of the advisor’s share of Fund assets, with the other two categories generally at 10% to 35% each.

Kalmar Investment Advisers (Kalmar) uses original and in-depth fundamental research to discover solid, well-managed growth companies that may not be appropriately understood by many growth investors and can therefore be purchased at undervalued levels. Kalmar intends to hold these stocks for the longer term. Companies that meet Kalmar’s “growth-with-value” investment criteria have, among other things, strong growth potential, reasonable valuation, products of value, attractive or improving balance sheets and financial returns, and conservative accounting.

Century Capital Management, LLC (Century Capital), employs a fundamental, bottom-up investment approach that attempts to identify reasonably priced companies that will grow faster than the overall market. Independent research is a core tenet. Senior analysts are expected to make at least 60 to 80 company visits per year, including meeting with the second or third tier of management. The ideal investment is a reasonably valued, well-managed company with established products or services, a high return on equity, high recurring revenues, and improving margins.

Chartwell Investment Partners, Inc. (Chartwell), 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.

Stephens Investment Management Group, LLC (SIMG), employs a disciplined, bottom-up investment selection process that combines rigorous fundamental analysis with quantitative screening in an effort to identify companies that exhibit potential for superior earnings growth that is unrecognized by the markets. SIMG has two screens—one for core growth stocks and one for catalyst stocks. Core growth stocks have strong growth franchises, recurring revenue, and above-average growth rates; catalyst stocks, in comparison, are experiencing change that could lead to accelerated earnings growth. There are common elements in both types of stocks, such as higher forward growth rates, above-median price/earnings ratios, higher return on equity, and positive earnings revisions.

Arrowpoint Asset Management, LLC (Arrowpoint Partners), uses in-depth, fundamental research to uncover companies that, in its opinion, can control their own economic destiny. Arrowpoint Partners starts by identifying businesses with strong competitive advantages in industries with high barriers to entry. Arrowpoint Partners then narrows its focus to companies with large potential markets and high-quality business models focused on the future. Finally, Arrowpoint Partners minimizes potential downside risk, resulting in a diversified portfolio of stable growth companies, cyclical share gainers, and to a lesser extent, game-changing growth businesses that Arrowpoint Partners feels will deliver returns beyond those of the benchmark index over time.

The Vanguard Group, Inc. (Vanguard), constructs a broadly diversified portfolio of small-cap domestic growth stocks based on its assessment of the relative return potential of the underlying securities. Vanguard selects securities that it believes offer a good balance between reasonable valuations and attractive earnings growth prospects relative to their small-cap domestic growth peers. Vanguard implements its stock selection process through the use of quantitative models to evaluate all of the securities in the Fund’s benchmark, the Russell 2500 Growth Index, while maintaining a risk profile similar to that of the Index.

The Fund is subject to manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. In addition, significant investment in the information technology sector subjects the Fund to proportionately higher exposure to the risks of this sector.

Other Investment Policies and Risks

In addition to investing in common stocks of small companies with growth potential, the Fund may make other kinds of investments to achieve its objective.

Although the Fund typically does not make significant investments in foreign securities, it reserves the right to invest up to 25% of its assets in foreign securities, which may include depositary receipts. 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 up to 15% of its net assets in restricted securities with limited marketability or in other illiquid securities.

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, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index (such as the S&P 500 Index), or a reference rate (such as LIBOR). Investments in derivatives may subject the Fund to risks different from, and possibly greater than, those of investments directly in 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 foreign currency exchange forward contracts, which are a type of derivative. A foreign currency exchange forward 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. Advisors of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in currency exchange rates. These contracts, however, would not prevent the Fund’s securities from falling in value as a result of risks other than unfavorable currency exchange movements.

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. Non-exchange-traded derivatives (such

as certain swap agreements and foreign currency exchange forward contracts),

on the other hand, tend to be more specialized or complex and may be harder

to value.

To facilitate cash flows to and from the Fund’s advisors, Vanguard typically invests a small portion of the Fund’s assets in stock index futures, which are a type of derivative, and/or shares of exchange-traded funds (ETFs), including ETF Shares issued by Vanguard stock funds. These stock index futures and ETFs typically provide returns similar to those of common stocks. Vanguard may also 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 Fund assets invested 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.

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when an advisor believes that doing so is 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 its normal limits in derivatives or exchange-traded funds that are consistent with the Fund’s objective when those instruments are more favorably priced or provide needed liquidity, as might be the case if 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, the 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 and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index 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. These policies and procedures do not apply to Vanguard ETF^®Shares because frequent trading in ETF Shares does not disrupt portfolio management or otherwise harm fund shareholders. 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 because the investor has a history of frequent trading or if Vanguard determines that such purchase may negatively affect a fund’s operation or performance.

• Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) 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 Vanguard fund (other than money market funds), in determining its net asset value, will use fair-value pricing when appropriate, 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 generally 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 small-cap growth funds was approximately 79%, as reported by Morningstar, Inc., on October 31, 2013.

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 more than 170 mutual funds holding assets of approximately $2.5 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, and equipment.

Vanguard Marketing Corporation 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 a fund (in the case of a fund with multiple share classes) pays its allocated share of the Vanguard funds’ 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.

• The Vanguard Group, Inc., P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Equity Investment Group. As of October 31, 2013, Vanguard served as advisor for approximately $2 trillion in assets.

The Fund pays each of its investment advisors (other than Vanguard) a base fee plus or minus a performance adjustment. Each base fee, which is paid quarterly, is a percentage of average daily net assets managed by the advisor during the most recent fiscal quarter. The base fee has breakpoints, which means that the percentage declines as assets go up. The performance adjustment, also paid quarterly, is based on the cumulative total return of each advisor’s portion of the Fund relative to that of the Russell 2500 Growth Index (for Arrowpoint Partners, Kalmar, SIMG, and Wellington Management), the Russell 2000 Growth Index (for Chartwell), a 50/50 blend of the Russell 2000 Growth Index and the Russell 2500 Growth Index (for Granahan), or a 50/50 blend of the Russell 2500 Index and the Russell 2500 Growth Index (for Century Capital) over the preceding 36-month period (60-month period for Arrowpoint Partners and SIMG). When the performance adjustment is positive, the Fund’s expenses increase; when it is negative, expenses decrease. Vanguard provides investment advisory services for a portion of the Fund on an at-cost basis.

For the fiscal year ended October 31, 2013, the aggregate advisory fees and expenses represented an effective annual rate of 0.21% of the Fund’s average net assets before a performance-based decrease of less than 0.01%.

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. As the Fund’s sponsor and overall manager,

Vanguard may provide additional 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 with Granahan and SIMG, 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. Income and capital gains distributions, if any, 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 or 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 have 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.

• 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.

Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to a 3.8% Medicare contribution tax on “net investment income.” Net investment income takes into account distributions paid by the Fund and capital gains from any sale or exchange of Fund shares.

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.

• 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 offered for sale in the United States (Vanguard U.S. funds), including the Fund offered in this prospectus, generally are not sold outside the United States, except to certain qualified investors. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments in Vanguard U.S. funds. Foreign investors should visit the Non-U.S. Investors page on our website at vanguard.com for information on Vanguard’s non-U.S. products.

Invalid addresses. If a dividend or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest the distribution and all future distributions until you provide us with a valid mailing address. Reinvestments will receive the net asset value calculated on the date of the reinvestment.

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, allocated to each share class by the number of Fund shares outstanding for that class. On U.S. holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not sell or redeem shares. 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) or country-specific or regional/global (e.g., natural disaster, economic or political news, act of terrorism, interest rate change). 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 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 vanguard.com/prices.

Financial Highlights

The following financial highlights tables are 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 each 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). The information for the six-month period ended April 30, 2014, has not been audited by an independent registered public accounting firm. The information for all periods in each table through October 31, 2013, has been obtained 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 by visiting vanguard.com or by contacting Vanguard by telephone or mail.

Plain Talk About How to Read the Financial Highlights Tables

This explanation uses the Fund’s Investor Shares as an example. The Investor

Shares began fiscal period ended April 30, 2014, with a net asset value (share

price) of $X.XX per share. During the period, each Investor Share earned $X.XX

from investment income (interest and dividends) and $X.XX from investments

that had appreciated in value or that were sold for higher prices than the Fund

paid for them.

Shareholders received $X.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 period was $X.XX, reflecting earnings of $X.XX

per share and distributions of $X.XX per share. This was an increase of $X.XX per

share (from $X.XX at the beginning of the period to $X.XX at the end of the

period). For a shareholder who reinvested the distributions in the purchase of

more shares, the total return was X.XX% for the period.

As of April 30, 2014, the Investor Shares had approximately $XX billion in net

assets. For the period, the annualized expense ratio was X.XX% ($X.XX per

$1,000 of net assets), and the annualized net investment income amounted to

X.XX% of average net assets. The Fund sold and replaced securities valued at an

annual rate of XX% of its net assets.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Vanguard fund shares can be held directly with Vanguard or indirectly through an intermediary, such as a bank, a broker, or an investment advisor. If you hold Vanguard fund shares directly with Vanguard, you should carefully read each topic within this section that pertains to your relationship with Vanguard. If you hold Vanguard fund shares indirectly through an intermediary (including shares held through a Vanguard brokerage account), please see Investing With Vanguard Through Other Firms, and also refer to your account agreement with the intermediary for information about transacting in that account. Vanguard reserves the right to change the following policies without notice. Please call or check online for current information. See

Contacting Vanguard.

For Vanguard fund shares held directly with Vanguard, 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. Note that each reference to “you” in this prospectus applies to any one or more registered account owners or persons authorized to transact on your account.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open, convert shares to, 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. $3,000.

To add to an existing account. Generally $100 (other than by Automatic Investment Plan, which has no established minimum).

Account Minimums for Admiral Shares

To open and maintain an account. $50,000. If you request Admiral Shares when you open a new account but the investment amount does not meet the account minimum for Admiral Shares, your investment will be placed in Investor Shares of the Fund. Institutional and financial intermediary clients should contact Vanguard for information on special eligibility rules that may apply to them.

To add to an existing account. Generally $100 (other than by Automatic Investment Plan, which has no established minimum).

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 trading (a business day).

For purchases by check into all funds other than money market funds and for purchases by exchange, wire, or electronic bank transfer (not using an Automatic Investment Plan) 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 for the purchase 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 for the purchase 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 for the purchase 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 for the purchase 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 for the purchase 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 the date you designated for withdrawal of funds from your bank account. Your bank account generally will be debited on the business day after your trade date. If the date you designated for withdrawal of funds from your bank account falls on a weekend, holiday, or other nonbusiness day, your trade date generally will be the previous business day.

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 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. Certain types of accounts may require additional documentation.

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 the investor has a history of frequent trading 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.

Converting Shares

When a conversion occurs, you receive shares of one class in place of shares of another class of the same fund. At the time of conversion, the dollar value of the “new” shares you receive equals the dollar value of the “old” shares that were converted. In other words, the conversion has no effect on the value of your investment in the fund at the time of the conversion. However, the number of shares you own after the conversion may be greater than or less than the number of shares you owned before the conversion, depending on the net asset values of the two share classes.

Vanguard will not accept your request to cancel any self-directed conversion request once processing has begun. Please be careful when placing a conversion request.

A conversion between share classes of the same fund is a nontaxable event.

Trade Date

The trade date for any conversion request received in good order will depend on the day and time Vanguard receives your request. Your conversion will be executed using the NAVs of the different share classes on the trade date. NAVs are calculated only on days that the NYSE is open for trading (a business day).

For a conversion request 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. For a conversion request 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. See Other Rules You Should Know.

Conversions From Investor Shares to Admiral Shares

Self-directed conversions. If your account balance in the Fund is at least $50,000, you may ask Vanguard to convert your Investor Shares to Admiral Shares. You may request a conversion through our website (if you are registered for online access), by telephone, or by mail. Institutional and financial intermediary clients should contact Vanguard for information on special eligibility rules that may apply to them. See

Contacting Vanguard.

Automatic conversions. Vanguard conducts periodic reviews of account balances and may, if your account balance in the Fund exceeds $50,000, automatically convert your Investor Shares to Admiral Shares. You will be notified before an automatic conversion occurs and will have an opportunity to instruct Vanguard not to effect the conversion. Institutional and financial intermediary clients should contact Vanguard for information on special eligibility rules that may apply to them.

Mandatory Conversions to Investor Shares

If an account no longer meets the balance requirements for Admiral Shares, Vanguard may automatically convert the shares in the account to Investor Shares. A decline in the account balance because of market movement may result in such a conversion. Vanguard will notify the investor in writing before any mandatory conversion occurs.

Redeeming Shares

How to Initiate a Redemption Request

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

Online. You may request a redemption of shares or request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to request a redemption of shares or an exchange. 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 service 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 service is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or upon request. Your redemption request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. To receive your proceeds by wire, you may instruct Vanguard to wire your redemption proceeds ($100 minimum) to a previously designated bank account. To establish the wire redemption service, you generally 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 registered for online access), by telephone, or by written request. See Exchanging Shares.

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, and generally to the address of record.

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 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 all other 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 generally 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 send the proceeds of the redemption to you by check, generally payable to all registered account owners, or use your proceeds to purchase new shares of the fund from 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 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 Limitations 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 seven 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. Share certificates are no longer issued for Vanguard funds. Shares currently held in certificates cannot be redeemed, exchanged, converted, or transferred (reregistered) 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 up to a 14-day restriction on your ability to request check 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, or wire your redemption proceeds, 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 or a notarized signature. 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.

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 registered for online access), by telephone, or by written request. 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. See Frequent-Trading Limitations for additional restrictions on exchanges.

Frequent-Trading Limitations

Because excessive transactions can disrupt management of a fund and increase the fund’s costs for all shareholders, the board of trustees of each Vanguard fund places certain limits on frequent trading in the funds. Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) 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 these frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the limitations apply to exchanges made online or by telephone.

These frequent-trading limitations do 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.

• Redemptions of shares to remove excess shareholder contributions to certain types of retirement accounts (including, but not limited to, IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans).

• Transaction requests submitted by mail to Vanguard from shareholders who hold their accounts directly with Vanguard or through a Vanguard brokerage account. (Transaction requests submitted by fax, if otherwise permitted, are subject to the limitations.)

• 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 limitations.)

For participants in employer-sponsored defined contribution plans,* the frequent-trading limitations do 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 written request to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are subject to the limitations.)

* The following Vanguard fund accounts are subject to the frequent-trading limitations: SEP-IRAs, SIMPLE IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans.

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 and/or redemption fees, intermediaries will be asked to assess these fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent-trading limitations 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 limitations. 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 summary prospectus (or prospectus) and/or shareholder 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 online. See Contacting Vanguard.

Vanguard.com

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

Electronic delivery. Vanguard can deliver your account statements, transaction confirmations, prospectuses, tax forms, and shareholder 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 preferences under “Account Maintenance.” You can revoke your electronic consent at any time through our website, 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 will automatically enable you to do business with us by telephone, unless you instruct us otherwise in writing.

Tele-Account^®. To obtain fund and account information through Vanguard’s automated telephone service, you must first establish a Personal Identification Number (PIN) by calling Tele-Account at 800-662-6273.

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.

Good Order

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

• Are provided by the person(s) authorized in accordance with Vanguard’s policies and procedures to access the account and request transactions.

• Include the fund name and account number.

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

Written instructions also must include:

• Signature guarantees or notarized signatures, if required for the type of transaction.

(Call Vanguard for specific requirements.)

• Any supporting documentation that may be required.

The requirements vary among types of accounts and transactions. For more information, consult our website at vanguard.com or see Contacting Vanguard.

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, Redeeming Shares, and

Exchanging 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 generally will accept 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 or other information 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. Vanguard may be required to transfer assets related to uncashed checks to a state under the state’s abandoned property law.

Dormant Accounts

If your account has no activity in it for a period of time, Vanguard may be required to transfer it to a state under the state’s abandoned property law.

Unusual Circumstances

If you experience difficulty contacting Vanguard online or by telephone, 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, a broker, or an 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 Limitations—Accounts Held by Intermediaries for information about the assessment of any purchase or redemption fees and the monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

Vanguard charges a $20 account service fee on 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 the account minimum. 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 institutional clients.

• Accounts held by Voyager, Voyager Select, and Flagship clients. Eligibility is based

on total household assets held at Vanguard, with a minimum of $50,000 to qualify for Vanguard Voyager Services^®, $500,000 for Vanguard Voyager Select Services^®, and $1 million for Vanguard Flagship Services^®. Vanguard determines eligibility by aggregating assets of all qualifying 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^®, certain annuities through Vanguard, the Vanguard 529 Plan, and certain small-business accounts. Assets in employer-sponsored retirement plans for which Vanguard provides recordkeeping services may be included in determining eligibility if the investor also has a personal account holding Vanguard mutual funds. Note that assets held in a Vanguard Brokerage Services account (other than Vanguard funds, including Vanguard ETFs) are not included when determining a household’s eligibility.

• 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 Individual 403(b)(7) Custodial Accounts, Vanguard Retirement Investment Program pooled plans, and Vanguard Individual 401(k) Plans.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the account minimum 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 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 Vanguard reasonably believes 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 purchase fee, 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, Vanguard reasonably believes 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 through our website, 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. 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 through our website, whichever you prefer) quarterly portfolio summaries to help you keep track of your accounts throughout the year. If you prefer, you may request to receive monthly portfolio summaries. 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 quarter (or month). Promptly review each summary that we provide to you. 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.

Tax Information Statements

For most accounts, we are required to provide annual tax forms to assist you in preparing your income tax returns. We will generally send (or provide through our website, whichever you prefer) annual tax forms in January. These forms 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 of vanguard.com can also view these forms through our website. Vanguard may also provide you with additional tax-related documentation. For more information, consult our website at vanguard.com or see Contacting Vanguard.

Annual and Semiannual Reports

We will send (or provide through our website, whichever you prefer) reports about Vanguard Explorer Fund twice a year, in June and December. These 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 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 30 calendar days after the end of the 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 15 calendar days after the end of the calendar quarter. Additionally, we generally post the ten largest stock portfolio holdings of the Fund as of the end of the most recent month. This list is generally updated 10 business days after the end of the month. 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.

DESCRIPTION OF THE TRUST

Vanguard Explorer Fund (the Trust) currently offers the following fund and share classes (identified by ticker symbol):


	Share Classes¹
Fund	Investor	Admiral
Vanguard Explorer Fund	VEXPX	VEXRX
1 Individually, a class; collectively, the classes.

The Trust has the ability to offer additional funds or classes of shares. There is no limit on the number of full and fractional shares that may be issued for a single fund or class of shares.

Organization

The Trust was organized as a Delaware corporation in 1967 and reorganized as a Maryland corporation in 1973. It was subsequently reorganized as a Delaware statutory trust in 1998. Prior to its reorganization as a Delaware statutory trust, the Trust was known as Vanguard Explorer Fund, Inc. The Trust is registered with the United States Securities and Exchange Commission (SEC) under the Investment Company Act of 1940 (the 1940 Act) as an open-end, management investment company. Vanguard Explorer Fund (the Fund) is classified as diversified within the meaning of the 1940 Act.

Service Providers

Custodian. Brown Brothers Harriman & Co., 40 Water Street, Boston, MA 02109, serves as the Fund‘s custodian. The custodian is responsible for maintaining the Fund‘s assets, keeping all necessary accounts and records of Fund assets, and appointing any foreign subcustodians or foreign securities depositories.

B-1

Independent Registered Public Accounting Firm. PricewaterhouseCoopers LLP, Two Commerce Square, Suite 1700, 2001 Market Street, Philadelphia, PA 19103-7042, serves as the Fund‘s independent registered public accounting firm. The independent registered public accounting firm audits the Fund‘s annual financial statements and provides other related services.

Transfer and Dividend-Paying Agent. The Fund‘s transfer agent and dividend-paying agent is Vanguard, P.O. Box 2600, Valley Forge, PA 19482.

Characteristics of the Fund‘s Shares

Restrictions on Holding or Disposing of Shares. There are no restrictions on the right of shareholders to retain or dispose of the Fund’s shares, other than those described in the Fund’s current prospectus and elsewhere in this Statement of Additional Information. The Fund or class may be terminated by reorganization into another mutual fund or class or by liquidation and distribution of the assets of the Fund or class. Unless terminated by reorganization or liquidation, the Fund and share classes will continue indefinitely.

Shareholder Liability. The Trust is organized under Delaware law, which provides that shareholders of a statutory trust are entitled to the same limitations of personal liability as shareholders of a corporation organized under Delaware law. This means that a shareholder of the Fund generally will not be personally liable for payment of the Fund’s debts. Some state courts, however, may not apply Delaware law on this point. We believe that the possibility of such a situation arising is remote.

Dividend Rights. The shareholders of each class of the Fund are entitled to receive any dividends or other distributions declared by the Fund for each such class. No shares of the Fund have priority or preference over any other shares of the Fund with respect to distributions. Distributions will be made from the assets of the Fund and will be paid ratably to all shareholders of a particular class according to the number of shares of the class held by shareholders on the record date. The amount of dividends per share may vary between separate share classes of the Fund based upon differences in the net asset values of the different classes and differences in the way that expenses are allocated between share classes pursuant to a multiple class plan approved by the Fund’s board of trustees.

Voting Rights. Shareholders are entitled to vote on a matter if (1) the matter concerns an amendment to the Declaration of Trust that would adversely affect to a material degree the rights and preferences of the shares of the Fund or any class; (2) the trustees determine that it is necessary or desirable to obtain a shareholder vote; (3) a merger or consolidation, share conversion, share exchange, or sale of assets is proposed and a shareholder vote is required by the 1940 Act to approve the transaction; or (4) a shareholder vote is required under the 1940 Act. The 1940 Act requires a shareholder vote under various circumstances, including to elect or remove trustees upon the written request of shareholders representing 10% or more of the Fund’s net assets, to change any fundamental policy of the Fund, and to enter into certain merger transactions. Unless otherwise required by applicable law, shareholders of the Fund receive one vote for each dollar of net asset value owned on the record date and a fractional vote for each fractional dollar of net asset value owned on the record date. However, only the shares of the Fund or class affected by a particular matter are entitled to vote on that matter. In addition, each class has exclusive voting rights on any matter submitted to shareholders that relates solely to that class, and each class has separate voting rights on any matter submitted to shareholders in which the interests of one class differ from the interests of another. Voting rights are noncumulative and cannot be modified without a majority vote.

Liquidation Rights. In the event that the Fund is liquidated, shareholders will be entitled to receive a pro rata share of the Fund’s net assets. In the event that a class of shares is liquidated, shareholders of that class will be entitled to receive a pro rata share of the Fund’s net assets that are allocated to that class. Shareholders may receive cash, securities, or a combination of the two.

Preemptive Rights. There are no preemptive rights associated with the Fund‘s shares.

Conversion Rights. Fund shareholders may convert their shares to another class of shares of the same Fund upon the satisfaction of any then-applicable eligibility requirements as described in the Fund’s current prospectus.

Redemption Provisions. The Fund’s redemption provisions are described in its current prospectus and elsewhere in this Statement of Additional Information.

Sinking Fund Provisions. The Fund has no sinking fund provisions.

Calls or Assessment. The Fund’s shares, when issued, are fully paid and non-assessable.

B-2

Tax Status of the Fund

The Fund expects to qualify each year for treatment as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the IRC). This special tax status means that the Fund will not be liable for federal tax on income and capital gains distributed to shareholders. In order to preserve its tax status, the Fund must comply with certain requirements. If the Fund fails to meet these requirements in any taxable year, the Fund will, in some cases, be able to cure such failure, including by paying a fund-level tax, paying interest, making additional distributions, or disposing of certain assets. If the Fund is ineligible to or otherwise does not cure such failure for any year, it will be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, will be taxable to shareholders as ordinary income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before regaining its tax status as a regulated investment company.

Dividends received and distributed by the Fund on shares of stock of domestic corporations may be eligible for the dividends-received deduction applicable to corporate shareholders. Corporations must satisfy certain requirements in order to claim the deduction. Capital gains distributed by the Fund are not eligible for the dividends-received deduction.

The Fund may invest in passive foreign investment companies (PFICs). A foreign company is generally a PFIC if 75% or more of its gross income is passive or if 50% or more of its assets produce passive income. Capital gains on the sale of an interest in a PFIC will be deemed ordinary income regardless of how long the Fund held it. Also, the Fund may be subject to corporate income tax and an interest charge on certain dividends and capital gains earned in respect to PFIC interests, whether or not such amounts are distributed to shareholders. To avoid such tax and interest, the Fund may elect to “mark to market” its PFIC interests, that is, to treat such interests as sold on the last day of the Fund’s fiscal year and to recognize any unrealized gains (or losses, to the extent of previously recognized gains) as ordinary income each year. Distributions from the Fund that are attributable to income or gains earned in respect to PFIC interests are characterized as ordinary income.

The Fund may declare a capital gain distribution consisting of the excess of net realized long-term capital gains over net realized short-term capital losses. Net capital gains for a fiscal year are computed by taking into account any capital loss carryforwards of the Fund. For Fund fiscal years beginning on or after December 22, 2010, capital losses may be carried forward indefinitely and retain their character as either short-term or long-term. Under prior law, net capital losses could be carried forward for eight tax years and were treated as short-term capital losses. A Fund is required to use capital losses arising in fiscal years beginning on or after December 22, 2010, before using capital losses arising in fiscal years prior to December 22, 2010.

FUNDAMENTAL POLICIES

The Fund is subject to the following fundamental investment policies, which cannot be changed in any material way without the approval of the holders of a majority of the Fund’s shares. For these purposes, a “majority” of shares means shares representing the lesser of (1) 67% or more of the Fund’s net assets voted, so long as shares representing more than 50% of the Fund’s net assets are present or represented by proxy or (2) more than 50% of the Fund’s net assets.

Borrowing. The Fund may borrow money only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund.

Commodities. The Fund may invest in commodities only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund.

Diversification. With respect to 75% of its total assets, the Fund may not (1) purchase more than 10% of the outstanding voting securities of any one issuer or (2) purchase securities of any issuer if, as a result, more than 5% of the Fund’s total assets would be invested in that issuer’s securities. This limitation does not apply to obligations of the U.S. government or its agencies or instrumentalities.

Industry Concentration. The Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry.

Investment Objective. The investment objective of the Fund may not be materially changed without a shareholder vote.

Loans. The Fund may make loans to another person only as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund.

B-3

Real Estate. The Fund may not invest directly in real estate unless it is acquired as a result of ownership of securities or other instruments. This restriction shall not prevent the Fund from investing in securities or other instruments (1) issued by companies that invest, deal, or otherwise engage in transactions in real estate or (2) backed or secured by real estate or interests in real estate.

Senior Securities. The Fund may not issue senior securities except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund.

Underwriting. The Fund may not act as an underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 (the 1933 Act), in connection with the purchase and sale of portfolio securities.

Compliance with the fundamental policies previously described is generally measured at the time the securities are purchased. Unless otherwise required by the 1940 Act (as is the case with borrowing), if a percentage restriction is adhered to at the time the investment is made, a later change in percentage resulting from a change in the market value of assets will not constitute a violation of such restriction. All fundamental policies must comply with applicable regulatory requirements. For more details, see Investment Strategies and Nonfundamental Policies.

None of these policies prevents the Fund from having an ownership interest in Vanguard. As a part owner of Vanguard, the Fund may own securities issued by Vanguard, make loans to Vanguard, and contribute to Vanguard’s costs or other financial requirements. See Management of the Fund for more information.

INVESTMENT STRATEGIES AND NONFUNDAMENTAL POLICIES

Some of the investment strategies and policies described on the following pages and in the Fund’s prospectus set forth percentage limitations on the Fund’s investment in, or holdings of, certain securities or other assets. Unless otherwise required by law, compliance with these strategies and policies will be determined immediately after the acquisition of such securities or assets by the Fund. Subsequent changes in values, net assets, or other circumstances will not be considered when determining whether the investment complies with the Fund’s investment strategies and policies.

The following investment strategies and policies supplement the Fund’s investment strategies and policies set forth in the prospectus. With respect to the different investments discussed as follows, the Fund may acquire such investments to the extent consistent with its investment strategies and policies.

Borrowing. A fund’s ability to borrow money is limited by its investment policies and limitations; by the 1940 Act; and by applicable exemptions, no-action letters, interpretations, and other pronouncements issued from time to time by the SEC and its staff or any other regulatory authority with jurisdiction. Under the 1940 Act, a fund is required to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300% of the amount borrowed, with an exception for borrowings not in excess of 5% of the fund’s total assets made for temporary or emergency purposes. Any borrowings for temporary purposes in excess of 5% of the fund’s total assets must maintain continuous asset coverage. If the 300% asset coverage should decline as a result of market fluctuations or for other reasons, a fund may be required to sell some of its portfolio holdings within three days (excluding Sundays and holidays) to reduce the debt and restore the 300% asset coverage, even though it may be disadvantageous from an investment standpoint to sell securities at that time.

Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of a fund’s portfolio. Money borrowed will be subject to interest costs that may or may not be recovered by earnings on the securities purchased. A fund also may be required to maintain minimum average balances in connection with a borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

The SEC takes the position that transactions that have a leveraging effect on the capital structure of a fund or are economically equivalent to borrowing can be viewed as constituting a form of borrowing by the fund for purposes of the 1940 Act. These transactions can include entering into reverse repurchase agreements; engaging in mortgage-dollar-roll transactions; selling securities short (other than short sales “against-the-box”); buying and selling certain derivatives (such as futures contracts); selling (or writing) put and call options; engaging in sale-buybacks; entering into firm-commitment and standby-commitment agreements; engaging in when-issued, delayed-delivery, or forward-commitment transactions; and participating in other similar trading practices. (Additional discussion about a number of these transactions can be found on the following pages.) A borrowing transaction will not be considered to constitute the issuance, by a fund, of a

B-4

“senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund maintains an offsetting financial position; segregates liquid assets (with such liquidity determined by the advisor in accordance with procedures established by the board of trustees) equal (as determined on a daily mark-to-market basis) in value to the fund’s potential economic exposure under the borrowing transaction; or otherwise “covers” the transaction in accordance with applicable SEC guidance (collectively, “covers” the transaction). A fund may have to buy or sell a security at a disadvantageous time or price in order to cover a borrowing transaction. In addition, segregated assets may not be available to satisfy redemptions or to fulfill other obligations.

Common Stock. Common stock represents an equity or ownership interest in an issuer. Common stock typically entitles the owner to vote on the election of directors and other important matters, as well as to receive dividends on such stock. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds, other debt holders, and owners of preferred stock take precedence over the claims of those who own common stock.

Convertible Securities. Convertible securities are hybrid securities that combine the investment characteristics of bonds and common stocks. Convertible securities typically consist of debt securities or preferred stock that may be converted (on a voluntary or mandatory basis) within a specified period of time (normally for the entire life of the security) into a certain amount of common stock or other equity security of the same or a different issuer at a predetermined price. Convertible securities also include debt securities with warrants or common stock attached and derivatives combining the features of debt securities and equity securities. Other convertible securities with features and risks not specifically referred to herein may become available in the future. Convertible securities involve risks similar to those of both fixed income and equity securities. In a corporation’s capital structure, convertible securities are senior to common stock but are usually subordinated to senior debt obligations of the issuer.

The market value of a convertible security is a function of its “investment value” and its “conversion value.” A security’s “investment value” represents the value of the security without its conversion feature (i.e., a nonconvertible fixed income security). The investment value may be determined by reference to its credit quality and the current value of its yield to maturity or probable call date. At any given time, investment value is dependent upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer, and the seniority of the security in the issuer’s capital structure. A security’s “conversion value” is determined by multiplying the number of shares the holder is entitled to receive upon conversion or exchange by the current price of the underlying security. If the conversion value of a convertible security is significantly below its investment value, the convertible security will trade like nonconvertible debt or preferred stock and its market value will not be influenced greatly by fluctuations in the market price of the underlying security. In that circumstance, the convertible security takes on the characteristics of a bond, and its price moves in the opposite direction from interest rates. Conversely, if the conversion value of a convertible security is near or above its investment value, the market value of the convertible security will be more heavily influenced by fluctuations in the market price of the underlying security. In that case, the convertible security’s price may be as volatile as that of common stock. Because both interest rates and market movements can influence its value, a convertible security generally is not as sensitive to interest rates as a similar fixed income security, nor is it as sensitive to changes in share price as its underlying equity security. Convertible securities are often rated below investment grade or are not rated, and they are generally subject to a high degree of credit risk.

Although all markets are prone to change over time, the generally high rate at which convertible securities are retired (through mandatory or scheduled conversions by issuers or through voluntary redemptions by holders) and replaced with newly issued convertible securities may cause the convertible securities market to change more rapidly than other markets. For example, a concentration of available convertible securities in a few economic sectors could elevate the sensitivity of the convertible securities market to the volatility of the equity markets and to the specific risks of those sectors. Moreover, convertible securities with innovative structures, such as mandatory-conversion securities and equity-linked securities, have increased the sensitivity of the convertible securities market to the volatility of the equity markets and to the special risks of those innovations, which may include risks different from, and possibly greater than, those associated with traditional convertible securities. A convertible security may be subject to redemption at the option of the issuer at a price set in the governing instrument of the convertible security. If a convertible security held by a fund is subject to such redemption option and is called for redemption, the fund must allow the issuer to redeem the security, convert it into the underlying common stock, or sell the security to a third party.

B-5

Debt Securities. A debt security, sometimes called a fixed income security, consists of a certificate or other evidence of a debt (secured or unsecured) on which the issuing company or governmental body promises to pay the holder thereof a fixed, variable, or floating rate of interest for a specified length of time and to repay the debt on the specified maturity date. Some debt securities, such as zero-coupon bonds, do not make regular interest payments but are issued at a discount to their principal or maturity value. Debt securities include a variety of fixed income obligations, including, but not limited to, corporate bonds, government securities, municipal securities, convertible securities, mortgage-backed securities, and asset-backed securities. Debt securities include investment-grade securities, non-investment-grade securities, and unrated securities. Debt securities are subject to a variety of risks, such as interest rate risk, income risk, call/prepayment risk, inflation risk, credit risk, liquidity risk, and (in the case of foreign securities) country risk and currency risk. The reorganization of an issuer under the federal bankruptcy laws may result in the issuer’s debt securities being cancelled without repayment, repaid only in part, or repaid in part or in whole through an exchange thereof for any combination of cash, debt securities, convertible securities, equity securities, or other instruments or rights in respect to the same issuer or a related entity.

Debt Securities—Non-Investment-Grade Securities. Non-investment-grade securities, also referred to as “high-yield securities” or “junk bonds,” are debt securities that are rated lower than the four highest rating categories by a nationally recognized statistical rating organization (e.g., lower than Baa3/P-2 by Moody’s Investors Service, Inc. (Moody’s), or below BBB–/A-2 by Standard & Poor’s) or, if unrated, are determined to be of comparable quality by the fund’s advisor. These securities are generally considered to be, on balance, predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation, and they will generally involve more credit risk than securities in the investment-grade categories. Non-investment-grade securities generally provide greater income and opportunity for capital appreciation than higher quality securities, but they also typically entail greater price volatility and principal and income risk.

Analysis of the creditworthiness of issuers of high-yield securities may be more complex than for issuers of investment-grade securities. Thus, reliance on credit ratings in making investment decisions entails greater risks for high-yield securities than for investment-grade securities. The success of a fund’s advisor in managing high-yield securities is more dependent upon its own credit analysis than is the case with investment-grade securities.

Some high-yield securities are issued by smaller, less-seasoned companies, while others are issued as part of a corporate restructuring such as an acquisition, a merger, or a leveraged buyout. Companies that issue high-yield securities are often highly leveraged and may not have more traditional methods of financing available to them. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with investment-grade securities. Some high-yield securities were once rated as investment-grade but have been downgraded to junk-bond status because of financial difficulties experienced by their issuers.

The market values of high-yield securities tend to reflect individual issuer developments to a greater extent than do investment-grade securities, which in general react to fluctuations in the general level of interest rates. High-yield securities also tend to be more sensitive to economic conditions than are investment-grade securities. A projection of an economic downturn or of a sustained period of rising interest rates, for example, could cause a decline in junk-bond prices because the advent of a recession could lessen the ability of a highly leveraged company to make principal and interest payments on its debt securities. If an issuer of high-yield securities defaults, in addition to risking payment of all or a portion of interest and principal, a fund investing in such securities may incur additional expenses to seek recovery.

The secondary market on which high-yield securities are traded may be less liquid than the market for investment-grade securities. Less liquidity in the secondary trading market could adversely affect the ability of a fund’s advisor to sell a high-yield security or the price at which a fund’s advisor could sell a high-yield security, and it could also adversely affect the daily net asset value of fund shares. When secondary markets for high-yield securities are less liquid than the market for investment-grade securities, it may be more difficult to value the securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation because less reliable, objective data is available.

Except as otherwise provided in a fund’s prospectus, if a credit-rating agency changes the rating of a portfolio security held by a fund, the fund may retain the portfolio security if the advisor deems it in the best interests of shareholders.

B-6

Depositary Receipts. Depositary receipts are securities that evidence ownership interests in a security or a pool of securities that have been deposited with a “depository.” Depositary receipts may be sponsored or unsponsored and include American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), and Global Depositary Receipts (GDRs). For ADRs, the depository is typically a U.S. financial institution, and the underlying securities are issued by a foreign issuer. For other depositary receipts, the depository may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs are issued in registered form, denominated in U.S. dollars, and designed for use in the U.S. securities markets. Other depositary receipts, such as GDRs and EDRs, may be issued in bearer form and denominated in other currencies, and they are generally designed for use in securities markets outside the United States. Although the two types of depositary receipt facilities (sponsored and unsponsored) are similar, there are differences regarding a holder’s rights and obligations and the practices of market participants.

A depository may establish an unsponsored facility without participation by (or acquiescence of) the underlying issuer; typically, however, the depository requests a letter of nonobjection from the underlying issuer prior to establishing the facility. Holders of unsponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon the deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of noncash distributions, and the performance of other services. The depository of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the underlying issuer or to pass through voting rights to depositary receipt holders with respect to the underlying securities.

Sponsored depositary receipt facilities are created in generally the same manner as unsponsored facilities, except that sponsored depositary receipts are established jointly by a depository and the underlying issuer through a deposit agreement. The deposit agreement sets out the rights and responsibilities of the underlying issuer, the depository, and the depositary receipt holders. With sponsored facilities, the underlying issuer typically bears some of the costs of the depositary receipts (such as dividend payment fees of the depository), although most sponsored depositary receipt holders may bear costs such as deposit and withdrawal fees. Depositories of most sponsored depositary receipts agree to distribute notices of shareholder meetings, voting instructions, and other shareholder communications and information to the depositary receipt holders at the underlying issuer’s request.

For purposes of a fund’s investment policies, investments in depositary receipts will be deemed to be investments in the underlying securities. Thus, a depositary receipt representing ownership of common stock will be treated as common stock. Depositary receipts do not eliminate all of the risks associated with directly investing in the securities of foreign issuers.

Derivatives. A derivative is a financial instrument that has a value based on—or “derived from”—the values of other assets, reference rates, or indexes. Derivatives may relate to a wide variety of underlying references, such as commodities, stocks, bonds, interest rates, currency exchange rates, and related indexes. Derivatives include futures contracts and options on futures contracts, forward-commitment transactions, options on securities, caps, floors, collars, swap agreements, and other financial instruments. Some derivatives, such as futures contracts and certain options, are traded on U.S. commodity and securities exchanges, while other derivatives, such as swap agreements, are privately negotiated and entered into in the over-the-counter (OTC) market. As a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), certain swap agreements may be cleared through a clearinghouse and traded on an exchange or swap execution facility. New regulations could, among other things, increase the costs of such transactions. The risks associated with the use of derivatives are different from, and possibly greater than, the risks associated with investing directly in the securities, assets, or market indexes on which the derivatives are based. Derivatives are used by some investors for speculative purposes. Derivatives also may be used for a variety of purposes that do not constitute speculation, such as hedging, managing risk, seeking to stay fully invested, seeking to reduce transaction costs, seeking to simulate an investment in equity or debt securities or other investments, and seeking to add value by using derivatives to more efficiently implement portfolio positions when derivatives are favorably priced relative to equity or debt securities or other investments. There is no assurance that any derivatives strategy used by a fund’s advisor will succeed. The counterparties to the funds’ derivatives will not be considered the issuers thereof for purposes of certain provisions of the 1940 Act and the IRC, although such derivatives may qualify as securities or investments under such laws. The funds’ advisors, however, will monitor and adjust, as appropriate, the funds’ credit risk exposure to derivative counterparties.

B-7

Derivative products are highly specialized instruments that require investment techniques and risk analyses different from those associated with stocks, bonds, and other traditional investments. The use of a derivative requires an understanding not only of the underlying instrument but also of the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions.

The use of derivatives generally involves the risk that a loss may be sustained as a result of the insolvency or bankruptcy of the other party to the contract (usually referred to as a “counterparty”) or the failure of the counterparty to make required payments or otherwise comply with the terms of the contract. Additionally, the use of credit derivatives can result in losses if a fund’s advisor does not correctly evaluate the creditworthiness of the issuer on which the credit derivative is based.

Derivatives may be subject to liquidity risk, which exists when a particular derivative is difficult to purchase or sell. If a derivative transaction is particularly large or if the relevant market is illiquid (as is the case with many OTC derivatives), it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price.

Derivatives may be subject to pricing or “basis” risk, which exists when a particular derivative becomes extraordinarily expensive relative to historical prices or the prices of corresponding cash market instruments. Under certain market conditions, it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity.

Because many derivatives have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the derivative itself. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. A derivative transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

Like most other investments, derivative instruments are subject to the risk that the market value of the instrument will change in a way detrimental to a fund’s interest. A fund bears the risk that its advisor will incorrectly forecast future market trends or the values of assets, reference rates, indexes, or other financial or economic factors in establishing derivative positions for the fund. If the advisor attempts to use a derivative as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the derivative will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving derivative instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many derivatives (in particular, OTC derivatives) are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

Exchange-Traded Funds. A fund may purchase shares of exchange-traded funds (ETFs), including ETF Shares issued by other Vanguard funds. Typically, a fund would purchase ETF shares for the same reason it would purchase (and as an alternative to purchasing) futures contracts: to obtain exposure to all or a portion of the stock or bond market. ETF shares enjoy several advantages over futures. Depending on the market, the holding period, and other factors, ETF shares can be less costly and more tax-efficient than futures. In addition, ETF shares can be purchased for smaller sums, offer exposure to market sectors and styles for which there is no suitable or liquid futures contract, and do not involve leverage.

An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objective, strategies, and policies. The price of an ETF can fluctuate within a wide range, and a fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down. In addition, ETFs are subject to the following risks that do not apply to conventional funds: (1) the market price of an ETF’s shares may trade at a discount or a premium to their net asset value; (2) an active trading market for an ETF’s shares may not develop or be maintained; and (3) trading of an ETF’s shares may be halted by the activation of individual or marketwide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an ETF’s shares may also be halted if the shares are delisted from the exchange without first being listed on another exchange or if the listing exchange’s officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.

Most ETFs are investment companies. Therefore, a fund’s purchases of ETF shares generally are subject to the limitations on, and the risks of, a fund’s investments in other investment companies, which are described under the heading “Other Investment Companies.”

Vanguard ETF^®* Shares are exchange-traded shares that represent an interest in an investment portfolio held by Vanguard funds. A fund’s investments in Vanguard ETF Shares are also generally subject to the descriptions, limitations, and risks described under the heading “Other Investment Companies,” except as provided by an exemption granted by the SEC that permits registered investment companies to invest in a Vanguard fund that issues ETF Shares beyond the limits of Section 12(d)(1) of the 1940 Act, subject to certain terms and conditions.

Foreign Securities. Typically, foreign securities are considered to be equity or debt securities issued by entities organized, domiciled, or with a principal executive office outside the United States, such as foreign corporations and governments. Securities issued by certain companies organized outside the United States may not be deemed to be foreign securities if the company’s principal operations are conducted from the United States or when the company’s equity securities trade principally on a U.S. stock exchange. Foreign securities may trade in U.S. or foreign securities markets. A fund may make foreign investments either directly by purchasing foreign securities or indirectly by purchasing depositary receipts or depositary shares of similar instruments (depositary receipts) for foreign securities. Direct investments in foreign securities may be made either on foreign securities exchanges or in the OTC markets. Investing in foreign securities involves certain special risk considerations that are not typically associated with investing in securities of U.S. companies or governments.

Because foreign issuers are not generally subject to uniform accounting, auditing, and financial reporting standards and practices comparable to those applicable to U.S. issuers, there may be less publicly available information about certain foreign issuers than about U.S. issuers. Evidence of securities ownership may be uncertain in many foreign countries. As a result, there are multiple risks that could result in a loss to the fund, including, but not limited to, the risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of the transaction. Securities of foreign issuers are generally less liquid than securities of comparable U.S. issuers, and foreign investments may be effected through structures that may be complex or confusing. In certain countries, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in the United States. In addition, with respect to certain foreign countries, there is the possibility of expropriation or confiscatory taxation, political or social instability, war, terrorism, nationalization, limitations on the removal of funds or other assets, or diplomatic developments that could affect U.S. investments in those countries. Although an advisor will endeavor to achieve the most favorable execution costs for a fund’s portfolio transactions in foreign securities under the circumstances, commissions and other transaction costs are generally higher than those on U.S. securities. In addition, it is expected that the custodian arrangement expenses for a fund that invests primarily in foreign securities will be somewhat greater than the expenses for a fund that invests primarily in domestic securities. Certain foreign governments levy withholding or other taxes against dividend and interest income from or transactions in foreign securities. Although in some countries a portion of these taxes is recoverable by the fund, the nonrecovered portion of foreign withholding taxes will reduce the income received from such securities.

The value of the foreign securities held by a fund that are not U.S. dollar-denominated may be significantly affected by changes in currency exchange rates. The U.S. dollar value of a foreign security generally decreases when the value of the U.S. dollar rises against the foreign currency in which the security is denominated, and it tends to increase when the value of the U.S. dollar falls against such currency (as discussed under the heading “Foreign Securities—Foreign Currency Transactions,” a fund may attempt to hedge its currency risks). In addition, the value of fund assets may be affected by losses and other expenses incurred in converting between various currencies in order to purchase and sell foreign securities, as well as by currency restrictions, exchange control regulation, currency devaluations, and political and economic developments.

Foreign Securities—Emerging Market Risk. Investing in emerging market countries involves certain risks not typically associated with investing in the United States, and it imposes risks greater than, or in addition to, risks of investing in more developed foreign countries. These risks include, but are not limited to, the following: nationalization or expropriation of assets or confiscatory taxation; currency devaluations and other currency exchange rate fluctuations; greater social, economic, and political uncertainty and instability (including amplified risk of war and terrorism); more substantial government involvement in the economy; less government supervision and regulation of the securities markets and participants in those markets and possible arbitrary and unpredictable enforcement of securities regulations; controls on foreign investment and limitations on repatriation of invested capital and on the fund’s ability to

B-9

exchange local currencies for U.S. dollars; unavailability of currency-hedging techniques in certain emerging market countries; generally smaller, less seasoned, or newly organized companies; difference in, or lack of, auditing and financial reporting standards, which may result in unavailability of material information about issuers; difficulty in obtaining and/or enforcing a judgment in a court outside the United States; and greater price volatility, substantially less liquidity, and significantly smaller market capitalization of securities markets. Also, any change in the leadership or politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities. Furthermore, high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Custodial services and other investment-related costs are often more expensive in emerging market countries, which can reduce a fund’s income from investments in securities or debt instruments of emerging market country issuers.

Foreign Securities—Foreign Currency Transactions. The value in U.S. dollars of a fund’s non-dollar-denominated foreign securities may be affected favorably or unfavorably by changes in foreign currency exchange rates and exchange control regulations, and the fund may incur costs in connection with conversions between various currencies. To seek to minimize the impact of such factors on net asset values, a fund may engage in foreign currency transactions in connection with its investments in foreign securities. A fund will not speculate in foreign currency exchange and will enter into foreign currency transactions only to attempt to “hedge” the currency risk associated with investing in foreign securities. Although such transactions tend to minimize the risk of loss that would result from a decline in the value of the hedged currency, they also may limit any potential gain that might result should the value of such currency increase.

Currency exchange transactions may be conducted either on a spot (i.e., cash) basis at the rate prevailing in the currency exchange market or through forward contracts to purchase or sell foreign currencies. A forward currency contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are entered into with large commercial banks or other currency traders who are participants in the interbank market. Currency exchange transactions also may be effected through the use of swap agreements or other derivatives.

Currency exchange transactions may be considered borrowings. A currency exchange transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

By entering into a forward contract for the purchase or sale of foreign currency involved in underlying security transactions, a fund may be able to protect itself against part or all of the possible loss between trade and settlement dates for that purchase or sale resulting from an adverse change in the relationship between the U.S. dollar and such foreign currency. This practice is sometimes referred to as “transaction hedging.” In addition, when the advisor reasonably believes that a particular foreign currency may suffer a substantial decline against the U.S. dollar, a fund may enter into a forward contract to sell an amount of foreign currency approximating the value of some or all of its portfolio securities denominated in such foreign currency. This practice is sometimes referred to as “portfolio hedging.” Similarly, when the advisor reasonably believes that the U.S. dollar may suffer a substantial decline against a foreign currency, a fund may enter into a forward contract to buy that foreign currency for a fixed dollar amount.

A fund may also attempt to hedge its foreign currency exchange rate risk by engaging in currency futures, options, and “cross-hedge” transactions. In cross-hedge transactions, a fund holding securities denominated in one foreign currency will enter into a forward currency contract to buy or sell a different foreign currency (one that the advisor reasonably believes generally tracks the currency being hedged with regard to price movements). The advisor may select the tracking (or substitute) currency rather than the currency in which the security is denominated for various reasons, including in order to take advantage of pricing or other opportunities presented by the tracking currency or to take advantage of a more liquid or more efficient market for the tracking currency. Such cross-hedges are expected to help protect a fund against an increase or decrease in the value of the U.S. dollar against certain foreign currencies.

B-10

A fund may hold a portion of its assets in bank deposits denominated in foreign currencies, so as to facilitate investment in foreign securities as well as protect against currency fluctuations and the need to convert such assets into U.S. dollars (thereby also reducing transaction costs). To the extent these assets are converted back into U.S. dollars, the value of the assets so maintained will be affected favorably or unfavorably by changes in foreign currency exchange rates and exchange control regulations.

The forecasting of currency market movement is extremely difficult, and whether any hedging strategy will be successful is highly uncertain. Moreover, it is impossible to forecast with precision the market value of portfolio securities at the expiration of a forward currency contract. Accordingly, a fund may be required to buy or sell additional currency on the spot market (and bear the expense of such transaction) if its advisor’s predictions regarding the movement of foreign currency or securities markets prove inaccurate. In addition, the use of cross-hedging transactions may involve special risks and may leave a fund in a less advantageous position than if such a hedge had not been established. Because forward currency contracts are privately negotiated transactions, there can be no assurance that a fund will have flexibility to roll over a forward currency contract upon its expiration if it desires to do so. Additionally, there can be no assurance that the other party to the contract will perform its services thereunder.

Foreign Securities—Foreign Investment Companies. Some of the countries in which a fund may invest may not permit, or may place economic restrictions on, direct investment by outside investors. Fund investments in such countries may be permitted only through foreign government-approved or authorized investment vehicles, which may include other investment companies. Such investments may be made through registered or unregistered closed-end investment companies that invest in foreign securities. Investing through such vehicles may involve layered fees or expenses and may also be subject to the limitations on, and the risks of, a fund’s investments in other investment companies, which are described under the heading “Other Investment Companies.”

Futures Contracts and Options on Futures Contracts. Futures contracts and options on futures contracts are derivatives. A futures contract is a standardized agreement between two parties to buy or sell at a specific time in the future a specific quantity of a commodity at a specific price. The commodity may consist of an asset, a reference rate, or an index. A security futures contract relates to the sale of a specific quantity of shares of a single equity security or a narrow-based securities index. The value of a futures contract tends to increase and decrease in tandem with the value of the underlying commodity. The buyer of a futures contract enters into an agreement to purchase the underlying commodity on the settlement date and is said to be “long” the contract. The seller of a futures contract enters into an agreement to sell the underlying commodity on the settlement date and is said to be “short” the contract. The price at which a futures contract is entered into is established either in the electronic marketplace or by open outcry on the floor of an exchange between exchange members acting as traders or brokers. Open futures contracts can be liquidated or closed out by physical delivery of the underlying commodity or payment of the cash settlement amount on the settlement date, depending on the terms of the particular contract. Some financial futures contracts (such as security futures) provide for physical settlement at maturity. Other financial futures contracts (such as those relating to interest rates, foreign currencies, and broad-based securities indexes) generally provide for cash settlement at maturity. In the case of cash-settled futures contracts, the cash settlement amount is equal to the difference between the final settlement price on the last trading day of the contract and the price at which the contract was entered into. Most futures contracts, however, are not held until maturity but instead are “offset” before the settlement date through the establishment of an opposite and equal futures position.

The purchaser or seller of a futures contract is not required to deliver or pay for the underlying commodity unless the contract is held until the settlement date. However, both the purchaser and seller are required to deposit “initial margin” with a futures commission merchant (FCM) when the futures contract is entered into. Initial margin deposits are typically calculated as a percentage of the contract’s market value. If the value of either party’s position declines, that party will be required to make additional “variation margin” payments to settle the change in value on a daily basis. This process is known as “marking-to-market.” A futures transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

An option on a futures contract (or futures option) conveys the right, but not the obligation, to purchase (in the case of a call option) or sell (in the case of a put option) a specific futures contract at a specific price (called the “exercise” or “strike” price) any time before the option expires. The seller of an option is called an option writer. The purchase price of

B-11

an option is called the premium. The potential loss to an option buyer is limited to the amount of the premium plus transaction costs. This will be the case, for example, if the option is held and not exercised prior to its expiration date. Generally, an option writer sells options with the goal of obtaining the premium paid by the option buyer. If an option sold by an option writer expires without being exercised, the writer retains the full amount of the premium. The option writer, however, has unlimited economic risk because its potential loss, except to the extent offset by the premium received when the option was written, is equal to the amount the option is “in-the-money” at the expiration date. A call option is in-the-money if the value of the underlying futures contract exceeds the exercise price of the option. A put option is in-the-money if the exercise price of the option exceeds the value of the underlying futures contract. Generally, any profit realized by an option buyer represents a loss for the option writer.

A fund that takes the position of a writer of a futures option is required to deposit and maintain initial and variation margin with respect to the option, as previously described in the case of futures contracts. A futures option transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

The Fund intends to comply with Rule 4.5 under the Commodity Exchange Act (CEA), under which a mutual fund is conditionally excluded from the definition of the term Commodity Pool Operator (CPO). Accordingly, Vanguard is not subject to registration or regulation as a CPO with respect to the Fund under the CEA. The Fund will only enter into futures contracts and futures options that are traded on a U.S. or foreign exchange, board of trade, or similar entity or that are quoted on an automated quotation system.

Futures Contracts and Options on Futures Contracts—Risks. The risk of loss in trading futures contracts and in writing futures options can be substantial because of the low margin deposits required, the extremely high degree of leverage involved in futures and options pricing, and the potential high volatility of the futures markets. As a result, a relatively small price movement in a futures position may result in immediate and substantial loss (or gain) for the investor. For example, if at the time of purchase, 10% of the value of the futures contract is deposited as margin, a subsequent 10% decrease in the value of the futures contract would result in a total loss of the margin deposit, before any deduction for the transaction costs, if the account were then closed out. A 15% decrease would result in a loss equal to 150% of the original margin deposit if the contract were closed out. Thus, a purchase or sale of a futures contract, and the writing of a futures option, may result in losses in excess of the amount invested in the position. In the event of adverse price movements, a fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements (and segregation requirements, if applicable) at a time when it may be disadvantageous to do so. In addition, on the settlement date, a fund may be required to make delivery of the instruments underlying the futures positions it holds.

A fund could suffer losses if it is unable to close out a futures contract or a futures option because of an illiquid secondary market. Futures contracts and futures options may be closed out only on an exchange that provides a secondary market for such products. However, there can be no assurance that a liquid secondary market will exist for any particular futures product at any specific time. Thus, it may not be possible to close a futures or option position. Moreover, most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of future positions and subjecting some futures traders to substantial losses. The inability to close futures and options positions also could have an adverse impact on the ability to hedge a portfolio investment or to establish a substitute for a portfolio investment.

U.S. Treasury futures are generally not subject to such daily limits.

A fund bears the risk that its advisor will incorrectly predict future market trends. If the advisor attempts to use a futures

contract or a futures option as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the futures position will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving futures products can reduce the risk

B-12

of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments.

A fund could lose margin payments it has deposited with its FCM if, for example, the FCM breaches its agreement with the fund or becomes insolvent or goes into bankruptcy. In that event, the fund may be entitled to return of margin owed to it only in proportion to the amount received by the FCM’s other customers, potentially resulting in losses to the fund.

Interfund Borrowing and Lending. The SEC has granted an exemption permitting registered open-end Vanguard funds to participate in Vanguard’s interfund lending program. This program allows the Vanguard funds to borrow money from and lend money to each other for temporary or emergency purposes. The program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the program unless it receives a more favorable interest rate than is typically available from a bank for a comparable transaction; (2) no equity, taxable bond, or money market fund may loan money if the loan would cause its aggregate outstanding loans through the program to exceed 5%, 7.5%, or 10%, respectively, of its net assets at the time of the loan; and (3) a fund’s interfund loans to any one fund shall not exceed 5% of the lending fund’s net assets. In addition, a Vanguard fund may participate in the program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The boards of trustees of the Vanguard funds are responsible for overseeing the interfund lending program. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Investing for Control. The Vanguard funds invest in securities and other instruments for the sole purpose of achieving a specific investment objective. As such, they do not seek to acquire enough of a company’s outstanding voting stock to have control over management decisions. The Vanguard funds do not invest for the purpose of controlling a company’s management.

Options. An option is a derivative. An option on a security (or index) is a contract that gives the holder of the option, in return for the payment of a “premium,” the right, but not the obligation, to buy from (in the case of a call option) or sell to (in the case of a put option) the writer of the option the security underlying the option (or the cash value of the index) at a specified exercise price prior to the expiration date of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price (in the case of a call option) or to pay the exercise price upon delivery of the underlying security (in the case of a put option). The writer of an option on an index has the obligation upon exercise of the option to pay an amount equal to the cash value of the index minus the exercise price, multiplied by the specified multiplier for the index option. The multiplier for an index option determines the size of the investment position the option represents. Unlike exchange-traded options, which are standardized with respect to the underlying instrument, expiration date, contract size, and strike price, the terms of OTC options (options not traded on exchanges) generally are established through negotiation with the other party to the option contract. Although this type of arrangement allows the purchaser or writer greater flexibility to tailor an option to its needs, OTC options generally involve greater credit risk than exchange-traded options, which are guaranteed by the clearing organization of the exchanges where they are traded.

The buyer (or holder) of an option is said to be “long” the option, while the seller (or writer) of an option is said to be “short” the option. A call option grants to the holder the right to buy (and obligates the writer to sell) the underlying security at the strike price. A put option grants to the holder the right to sell (and obligates the writer to buy) the underlying security at the strike price. The purchase price of an option is called the “premium.” The potential loss to an option buyer is limited to the amount of the premium plus transaction costs. This will be the case if the option is held and not exercised prior to its expiration date. Generally, an option writer sells options with the goal of obtaining the premium paid by the option buyer, but that person could also seek to profit from an anticipated rise or decline in option prices. If an option sold by an option writer expires without being exercised, the writer retains the full amount of the premium. The option writer, however, has unlimited economic risk because its potential loss, except to the extent offset by the premium received when the option was written, is equal to the amount the option is “in-the-money” at the expiration date. A call option is in-the-money if the value of the underlying position exceeds the exercise price of the option. A put option is in-the-money if the exercise price of the option exceeds the value of the underlying position. Generally, any profit realized by an option buyer represents a loss for the option writer. The writing of an option will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to

B-13

borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

If a trading market in particular options were to become unavailable, investors in those options (such as the funds) would be unable to close out their positions until trading resumes, and they may be faced with substantial losses if the value of the underlying instrument moves adversely during that time. Even if the market were to remain available, there may be times when options prices will not maintain their customary or anticipated relationships to the prices of the underlying instruments and related instruments. Lack of investor interest, changes in volatility, or other factors or conditions might adversely affect the liquidity, efficiency, continuity, or even the orderliness of the market for particular options.

A fund bears the risk that its advisor will not accurately predict future market trends. If the advisor attempts to use an option as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the option will have or will develop imperfect or no correlation with the portfolio investment, which could cause substantial losses for the fund. Although hedging strategies involving options can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many options, in particular OTC options, are complex and often valued based on subjective factors. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

Other Investment Companies. A fund may invest in other investment companies to the extent permitted by applicable law or SEC exemption. Under Section 12(d)(1) of the 1940 Act, a fund generally may invest up to 10% of its assets in shares of investment companies and up to 5% of its assets in any one investment company, as long as no investment represents more than 3% of the voting stock of an acquired investment company. In addition, no funds for which Vanguard acts as an advisor may, in the aggregate, own more than 10% of the voting stock of a closed-end investment company. The 1940 Act and related rules provide certain exemptions from these restrictions. If a fund invests in other investment companies, shareholders will bear not only their proportionate share of the fund’s expenses (including operating expenses and the fees of the advisor), but they also may indirectly bear the similar expenses of the underlying investment companies. Certain investment companies, such as business development companies (BDCs), are more akin to operating companies and, as such, their expenses are not direct expenses paid by fund shareholders and are not used to calculate the fund’s net asset value. SEC rules nevertheless require that any expenses incurred by a BDC be included in a fund’s expense ratio as “Acquired Fund Fees and Expenses.” The expense ratio of a fund that holds a BDC will thus overstate what the fund actually spends on portfolio management, administrative services, and other shareholder services by an amount equal to these Acquired Fund Fees and Expenses. The Acquired Fund Fees and Expenses are not included in a fund’s financial statements, which provide a clearer picture of a fund’s actual operating expenses. Shareholders would also be exposed to the risks associated not only with the investments of the fund but also with the portfolio investments of the underlying investment companies. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that typically trade on a stock exchange or over-the-counter at a premium or discount to their net asset value. Others are continuously offered at net asset value but also may be traded on the secondary market.

Preferred Stock. Preferred stock represents an equity or ownership interest in an issuer. Preferred stock normally pays dividends at a specified rate and has precedence over common stock in the event the issuer is liquidated or declares bankruptcy. However, in the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. Preferred stock, unlike common stock, often has a stated dividend rate payable from the corporation’s earnings. Preferred stock dividends may be cumulative or noncumulative, participating, or auction rate. “Cumulative” dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stock. “Participating” preferred stock may be entitled to a dividend exceeding the stated dividend in certain cases. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of such stocks to decline. Preferred stock may have mandatory sinking fund provisions, as well as provisions allowing the stock to be called or redeemed, which can limit the benefit of a decline in interest rates. Preferred stock is subject to many of the risks to which common stock and debt securities are subject. In addition, preferred stock may be subject to more abrupt or erratic price movements than common stock or debt securities because preferred stock may trade with less frequency and in more limited volume.

Repurchase Agreements. A repurchase agreement is an agreement under which a fund acquires a fixed income security (generally a security issued by the U.S. government or an agency thereof, a banker’s acceptance, or a certificate of deposit) from a commercial bank, a broker, or a dealer and simultaneously agrees to resell such security to the seller

B-14

at an agreed-upon price and date (normally, the next business day). Because the security purchased constitutes collateral for the repurchase obligation, a repurchase agreement may be considered a loan that is collateralized by the security purchased. The resale price reflects an agreed-upon interest rate effective for the period the instrument is held by a fund and is unrelated to the interest rate on the underlying instrument. In these transactions, the securities acquired by a fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and be held by a custodian bank until repurchased. In addition, the investment advisor will monitor a fund’s repurchase agreement transactions generally and will evaluate the creditworthiness of any bank, broker, or dealer party to a repurchase agreement relating to a fund. The aggregate amount of any such agreements is not limited, except to the extent required by law.

The use of repurchase agreements involves certain risks. One risk is the seller’s ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral may be delayed or limited. For example, if the other party to the agreement becomes insolvent and subject to liquidation or reorganization under the bankruptcy or other laws, a court may determine that the underlying security is collateral for a loan by the fund not within its control, and therefore the realization by the fund on such collateral may be automatically stayed. Finally, it is possible that the fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

Restricted and Illiquid Securities. Illiquid securities are securities that cannot be sold or disposed of within seven days in the ordinary course of business at approximately the price at which they are valued. The SEC generally limits aggregate holdings of illiquid securities by a mutual fund to 15% of its net assets (5% for money market funds). A fund may experience difficulty valuing and selling illiquid securities and, in some cases, may be unable to value or sell certain illiquid securities for an indefinite period of time. Illiquid securities may include a wide variety of investments, such as (1) repurchase agreements maturing in more than seven days (unless the agreements have demand/redemption features), (2) OTC options contracts and certain other derivatives (including certain swap agreements), (3) fixed time deposits that are not subject to prepayment or do not provide for withdrawal penalties upon prepayment (other than overnight deposits), (4) loan interests and other direct debt instruments, (5) certain municipal lease obligations, (6) commercial paper issued pursuant to Section 4(2) of the 1933 Act, and (7) securities whose disposition is restricted under the federal securities laws. Illiquid securities include restricted, privately placed securities that, under the federal securities laws, generally may be resold only to qualified institutional buyers. If a substantial market develops for a restricted security held by a fund, it may be treated as a liquid security, in accordance with procedures and guidelines approved by the board of trustees. This generally includes securities that are unregistered, that can be sold to qualified institutional buyers in accordance with Rule 144A under the 1933 Act, or that are exempt from registration under the 1933 Act, such as commercial paper. Although a fund’s advisor monitors the liquidity of restricted securities, the board of trustees oversees and retains ultimate responsibility for the advisor’s liquidity determinations. Several factors that the trustees consider in monitoring these decisions include the valuation of a security; the availability of qualified institutional buyers, brokers, and dealers that trade in the security; and the availability of information about the security’s issuer.

Reverse Repurchase Agreements. In a reverse repurchase agreement, a fund sells a security to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase that security at an agreed-upon price and time. Under a reverse repurchase agreement, the fund continues to receive any principal and interest payments on the underlying security during the term of the agreement. Reverse repurchase agreements involve the risk that the market value of securities retained by the fund may decline below the repurchase price of the securities sold by the fund that it is obligated to repurchase. A reverse repurchase agreement may be considered a borrowing transaction for purposes of the 1940 Act. A reverse repurchase agreement transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.” A fund will enter into reverse repurchase agreements only with parties whose creditworthiness has been reviewed and found satisfactory by the advisor. If the buyer in a reverse repurchase agreement becomes insolvent or files for bankruptcy, a fund’s use of proceeds from the sale may be restricted while the other party or its trustee or receiver determines if it will honor the fund’s right to repurchase the securities. If the fund is unable to recover the securities it sold in a reverse repurchase agreement, it would realize a loss equal to the difference between the value of the securities and the payment it received for them.

B-15

Securities Lending. A fund may lend its investment securities to qualified institutional investors (typically brokers, dealers, banks, or other financial institutions) who may need to borrow securities in order to complete certain transactions, such as covering short sales, avoiding failures to deliver securities, or completing arbitrage operations. By lending its investment securities, a fund attempts to increase its net investment income through the receipt of interest on the securities lent. Any gain or loss in the market price of the securities lent that might occur during the term of the loan would be for the account of the fund. If the borrower defaults on its obligation to return the securities lent because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities lent or in gaining access to the collateral. These delays and costs could be greater for foreign securities. If a fund is not able to recover the securities lent, a fund may sell the collateral and purchase a replacement investment in the market. The value of the collateral could decrease below the value of the replacement investment by the time the replacement investment is purchased. Cash received as collateral through loan transactions may be invested in other eligible securities. Investing this cash subjects that investment to market appreciation or depreciation. Currently, Vanguard funds that lend securities invest the cash collateral received in one or more Vanguard CMT Funds, which are very low-cost money market funds.

The terms and the structure of the loan arrangements, as well as the aggregate amount of securities loans, must be consistent with the 1940 Act and the rules or interpretations of the SEC thereunder. These provisions limit the amount of securities a fund may lend to 33 1/3% of the fund’s total assets and require that (1) the borrower pledge and maintain with the fund collateral consisting of cash, an irrevocable letter of credit, or securities issued or guaranteed by the U.S. government having at all times not less than 100% of the value of the securities lent; (2) the borrower add to such collateral whenever the price of the securities lent rises (i.e., the borrower “marks to market” on a daily basis); (3) the loan be made subject to termination by the fund at any time; and (4) the fund receives reasonable interest on the loan (which may include the fund’s investing any cash collateral in interest-bearing short-term investments), any distribution on the lent securities, and any increase in their market value. Loan arrangements made by each fund will comply with all other applicable regulatory requirements, including the rules of the New York Stock Exchange, which presently require the borrower, after notice, to redeliver the securities within the normal settlement time of three business days. The advisor will consider the creditworthiness of the borrower, among other things, in making decisions with respect to the lending of securities, subject to oversight by the board of trustees. At the present time, the SEC does not object if an investment company pays reasonable negotiated fees in connection with lent securities, so long as such fees are set forth in a written contract and approved by the investment company’s trustees. In addition, voting rights pass with the lent securities, but if a fund has knowledge that a material event will occur affecting securities on loan, and in respect to which the holder of the securities will be entitled to vote or consent, the lender must be entitled to call the loaned securities in time to vote or consent. A fund bears the risk that there may be a delay in the return of the securities, which may impair the fund’s ability to vote on such a matter.

Pursuant to Vanguard’s securities lending policy, Vanguard’s fixed income and money market funds are not permitted to, and do not, lend their investment securities.

Swap Agreements. A swap agreement, which is a type of derivative, is an agreement between two parties (counterparties) to exchange payments at specified dates (periodic payment dates) on the basis of a specified amount (notional amount) with the payments calculated with reference to a specified asset, reference rate, or index.

Examples of swap agreements include, but are not limited to, interest rate swaps, credit default swaps, equity swaps, commodity swaps, foreign currency swaps, index swaps, excess return swaps, and total return swaps. Most swap agreements provide that when the periodic payment dates for both parties are the same, payments are netted, and only the net amount is paid to the counterparty entitled to receive the net payment. Consequently, a fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement, based on the relative values of the positions held by each counterparty. Swap agreements allow for a wide variety of transactions. For example, fixed rate payments may be exchanged for floating rate payments; U.S. dollar-denominated payments may be exchanged for payments denominated in a different currency; and payments tied to the price of one asset, reference rate, or index may be exchanged for payments tied to the price of another asset, reference rate, or index.

An option on a swap agreement, also called a “swaption,” is an option that gives the buyer the right, but not the obligation, to enter into a swap on a future date in exchange for paying a market-based “premium.” A receiver swaption gives the owner the right to receive the total return of a specified asset, reference rate, or index. A payer swaption gives the owner the right to pay the total return of a specified asset, reference rate, or index. Swaptions also include options that allow an existing swap to be terminated or extended by one of the counterparties.

B-16

The use of swap agreements by a fund entails certain risks, which may be different from, or possibly greater than, the risks associated with investing directly in the securities and other investments that are the referenced asset for the swap agreement. Swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with stocks, bonds, and other traditional investments. The use of a swap requires an understanding not only of the referenced asset, reference rate, or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions.

Swap agreements may be subject to liquidity risk, which exists when a particular swap is difficult to purchase or sell. If a swap transaction is particularly large or if the relevant market is illiquid (as is the case with many OTC swaps), it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. In addition, swap transactions may be subject to a fund’s limitation on investments in illiquid securities.

Swap agreements may be subject to pricing risk, which exists when a particular swap becomes extraordinarily expensive or inexpensive relative to historical prices or the prices of corresponding cash market instruments. Under certain market conditions, it may not be economically feasible to initiate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity or to realize the intrinsic value of the swap agreement.

Because some swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain swaps have the potential for unlimited loss, regardless of the size of the initial investment. A leveraged swap transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

Like most other investments, swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to a fund’s interest. A fund bears the risk that its advisor will not accurately forecast future market trends or the values of assets, reference rates, indexes, or other economic factors in establishing swap positions for the fund. If the advisor attempts to use a swap as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the swap will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving swap instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other fund investments. Many swaps, OTC swaps in particular, are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a fund.

The use of a swap agreement also involves the risk that a loss may be sustained as a result of the insolvency or bankruptcy of the counterparty or the failure of the counterparty to make required payments or otherwise comply with the terms of the agreement. Additionally, the use of credit default swaps can result in losses if a fund’s advisor does not correctly evaluate the creditworthiness of the issuer on which the credit swap is based.

The market for swaps and swaptions is a relatively new market. It is possible that developments in the market could adversely affect a fund, including its ability to terminate existing swap agreements or to realize amounts to be received under such agreements. As previously noted under the heading “Derivatives,” under the Dodd-Frank Act, certain swaps that may be used by a fund may be cleared through a clearinghouse and traded on an exchange or swap execution facility.

Tax Matters—Federal Tax Discussion. Discussion herein of U.S. federal income tax matters summarizes some of the important, generally applicable U.S. federal tax considerations relevant to investment in a fund based on the IRC, U.S. Treasury regulations, and other applicable authority. These authorities are subject to change by legislative, administrative, or judicial action, possibly with retroactive effect. A shareholder should consult his or her tax professional for information regarding the particular situation and the possible application of U.S. federal, state, local, foreign, and other taxes.

Tax Matters—Federal Tax Treatment of Derivatives, Hedging, and Related Transactions. A fund’s transactions in derivative instruments (including, but not limited to, options, futures, forward contracts, and swap agreements), as well as any of the fund’s hedging, short sale, securities loan, or similar transactions, may be subject to one or more special tax rules that affect the treatment of gains or losses recognized by the fund as ordinary or capital. These transactions may also accelerate the recognition of income or gains to the fund, defer losses to the fund, and cause adjustments in the holding period of the fund’s securities.

B-17

In order for a fund to continue to qualify for federal income tax treatment as a regulated investment company, at least 90% of its gross income for a taxable year must be derived from qualifying income—i.e., dividends, interest, income derived from securities loans, gains from the sale of securities or foreign currencies, or other income derived with respect to the fund’s business of investing in securities or currencies. The funds generally expect that any net gain from options, futures, and forward contracts will be treated as qualifying income.

Tax Matters—Federal Tax Treatment of Futures Contracts. For federal income tax purposes, a fund generally must recognize, as of the end of each taxable year, any net unrealized gains and losses on certain futures contracts, as well as any gains and losses actually realized during the year. In these cases, any gain or loss recognized with respect to a futures contract is considered to be 60% long-term capital gain or loss and 40% short-term capital gain or loss, without regard to the holding period of the contract. Gains and losses on certain other futures contracts (primarily non-U.S. futures contracts) are not recognized until the contracts are closed and are treated as long-term or short-term, depending on the holding period of the contract. Sales of futures contracts that are intended to hedge against a change in the value of securities held by a fund may affect the holding period of such securities and, consequently, the nature of the gain or loss on such securities upon disposition. A fund may be required to defer the recognition of losses on one position, such as futures contracts, to the extent of any unrecognized gains on a related offsetting position held by the fund.

A fund will distribute to shareholders annually any net capital gains that have been recognized for federal income tax purposes on futures transactions. Such distributions will be combined with distributions of capital gains realized on the fund’s other investments, and shareholders will be advised on the nature of the distributions.

Tax Matters—Federal Tax Treatment of Non-U.S. Currency Transactions. Special rules govern the federal income tax treatment of certain transactions denominated in a currency other than the U.S. dollar, determined by reference to the value of one or more currencies other than the U.S. dollar and the disposition of a currency other than the U.S. dollar by a taxpayer whose functional currency is the U.S. dollar. However, foreign-currency-related regulated futures contracts and non-equity options are generally not subject to the special currency rules if they are or would be treated as sold for their fair market value at year-end under the marking-to-market rules applicable to other futures contracts unless an election is made to have such currency rules apply. With respect to transactions covered by the special rules, foreign currency gain or loss is calculated separately from any gain or loss on the underlying transaction and is normally taxable as ordinary income or loss. A taxpayer may elect to treat, as capital gain or loss, foreign currency gain or loss arising from certain identified forward contracts, futures contracts, and options that are capital assets in the hands of the taxpayer and that are not part of a straddle. The U.S. Treasury issued regulations under which certain transactions subject to the special currency rules that are part of a “section 988 hedging transaction” (as defined in the IRC and the U.S. Treasury regulations) will be integrated and treated as a single transaction or otherwise treated consistently for purposes of the IRC. Certain currency transactions may qualify as part of a “section 1221 hedging transaction,” which also has the effect of treating their components consistently. Any gain or loss attributable to the foreign currency component of a transaction engaged in by a fund that is not subject to the special currency rules (such as foreign equity investments other than certain preferred stocks) will be treated as a capital gain or loss and will not be segregated from the gain or loss on the underlying transaction. It is anticipated that some of the non-U.S. dollar-denominated investments and foreign currency contracts a fund may make or enter into will be subject to special currency rules described within this policy.

To the extent a fund engages in non-U.S. currency hedging, the fund may elect or be required to apply other rules that could affect the character and timing of the fund’s gains and losses. For more information, see “Tax Matters—Federal Tax Treatment of Derivatives, Hedging, and Related Transactions.”

Tax Matters—Foreign Tax Credit. Foreign governments may withhold taxes on dividends and interest paid with respect to foreign securities held by a fund. Foreign governments may also impose taxes on other payments or gains with respect to foreign securities. If, at the close of its fiscal year, more than 50% of a fund’s total assets are invested in securities of foreign issuers, the fund may elect to pass through to shareholders the ability to deduct or, if they meet certain holding period requirements, take a credit for foreign taxes paid by the fund. Similarly, if at the close of each quarter of a fund’s taxable year, at least 50% of its total assets consist of interests in other regulated investment companies, the fund is permitted to elect to pass through to its shareholders the foreign income taxes paid by the fund in connection with foreign securities held directly by the fund or held by a regulated investment company in which the fund invests that has elected to pass through such taxes to shareholders.

B-18

Tax Matters—Real Estate Mortgage Investment Conduits. If a fund invests directly or indirectly, including through a REIT or other pass-through entity, in residual interests in real estate mortgage investment conduits (REMICs) or equity interests in taxable mortgage pools (TMPs), a portion of the fund’s income that is attributable to a residual interest in a REMIC or an equity interest in a TMP (such portion referred to in the IRC as an “excess inclusion”) will be subject to U.S. federal income tax in all events—including potentially at the fund level—under a notice issued by the IRS in October 2006 and U.S. Treasury regulations that have yet to be issued but may apply retroactively. This notice also provides, and the regulations are expected to provide, that excess inclusion income of a registered investment company will be allocated to shareholders of the registered investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related interest directly. As a result, a fund investing in such interests may not be a suitable investment for charitable remainder trusts, as noted below. In general, excess inclusion income allocated to shareholders (1) cannot be offset by net operation losses (subject to a limited exception for certain thrift institutions); (2) will constitute unrelated business taxable income (UBTI) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan, or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity, which otherwise might not be required, to file a tax return and pay tax on such income; and (3) in the case of a non-U.S. investor, will not qualify for any reduction in U.S. federal withholding tax. A shareholder will be subject to U.S. federal income tax on such inclusions notwithstanding any exemption from such income tax otherwise available under the IRC. As a result, a fund investing in such interests may not be suitable for charitable remainder trusts. See “Tax Matters—Tax-Exempt Investors.”

Tax Matters—Tax Considerations for Non-U.S. Investors. U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments made by non-U.S. investors in Vanguard funds.

Tax Matters—Tax-Exempt Investors. Income of a fund that would be UBTI if earned directly by a tax-exempt entity will not generally be attributed as UBTI to a tax-exempt shareholder of the fund. Notwithstanding this “blocking” effect, a tax-exempt shareholder could realize UBTI by virtue of its investment in a fund if shares in the fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of IRC Section 514(b).

A tax-exempt shareholder may also recognize UBTI if a fund recognizes “excess inclusion income” derived from direct or indirect investments in residual interests in REMICs or equity interests in TMPs. See “Tax Matters—Real Estate Mortgage Investment Conduits.”

In addition, special tax consequences apply to charitable remainder trusts that invest in a fund that invests directly or indirectly in residual interests in REMICs or equity interests in TMPs. Charitable remainder trusts and other tax-exempt investors are urged to consult their tax advisors concerning the consequences of investing in a fund.

Warrants. Warrants are instruments that give the holder the right, but not the obligation, to buy an equity security at a specific price for a specific period of time. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company. A warrant ceases to have value if it is not exercised prior to its expiration date. These factors can make warrants more speculative than other types of investments.

When-Issued, Delayed-Delivery, and Forward-Commitment Transactions. When-issued, delayed-delivery, and forward-commitment transactions involve a commitment to purchase or sell specific securities at a predetermined price or yield in which payment and delivery take place after the customary settlement period for that type of security. Typically, no interest accrues to the purchaser until the security is delivered. When purchasing securities pursuant to one of these transactions, payment for the securities is not required until the delivery date. However, the purchaser assumes the rights and risks of ownership, including the risks of price and yield fluctuations and the risk that the security will not be issued as anticipated. When a fund has sold a security pursuant to one of these transactions, the fund does not participate in further gains or losses with respect to the security. If the other party to a delayed-delivery transaction fails to deliver or pay for the securities, the fund could miss a favorable price or yield opportunity or suffer a loss. A fund may renegotiate a when-issued or forward-commitment transaction and may sell the underlying securities before delivery, which may result in capital gains or losses for the fund. When-issued, delayed-delivery, and forward-commitment transactions will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to

B-19

borrowings by the fund, if the fund covers the transaction in accordance with the requirements described under the heading “Borrowing.”

Regulatory restrictions in India. Shares of Vanguard Explorer Fund have not been, and will not be, registered under the laws of India and are not intended to benefit from any laws in India promulgated for the protection of shareholders. As a result of regulatory requirements in India, shares of the Fund shall not be knowingly offered to (directly or indirectly) or sold or delivered to (within India); transferred to or purchased by; or held for, on the account of, or for the benefit of (1) a “person resident in India” (as defined in the Foreign Exchange Management Act, 1999), (2) a “non-resident Indian,” an “overseas corporate body,” or a “person of Indian origin,” (as each such term is defined in the Foreign Exchange Management (Deposit) Regulations, 2000), or (3) any other entity or person disqualified or otherwise prohibited from accessing the Indian securities market under applicable laws, as may be amended from time to time. Each investor, prior to purchasing shares of the Fund, must satisfy itself regarding compliance with these requirements.

SHARE PRICE

Multiple-class funds do not have a single share price. Rather, each class has a share price, called its net asset value, or NAV, that is calculated each business day as of the close of regular trading on the New York Stock Exchange (the Exchange), generally 4 p.m., Eastern time. NAV per share is computed by dividing the total assets, minus liabilities, allocated to each share class by the number of Fund shares outstanding for that class. On U.S. holidays or other days when the Exchange is closed, the NAV is not calculated, and the Fund does not sell or redeem shares. 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.

The Exchange typically observes the following holidays: New Year’s Day; Martin Luther King, Jr., Day; Presidents’ Day (Washington’s Birthday); Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day. Although the Fund expects the same holidays to be observed in the future, the Exchange may modify its holiday schedule or hours of operation at any time.

PURCHASE AND REDEMPTION OF SHARES

Purchase of Shares

The purchase price of shares of the Fund is the NAV per share next determined after the purchase request is received in good order, as defined in the Fund’s prospectus.

Exchange of Securities for Shares of the Fund. Shares of the Fund may be purchased “in kind” (i.e., in exchange for securities, rather than for cash) at the discretion of the Fund’s portfolio manager. Such securities must not be restricted as to transfer and must have a value that is readily ascertainable. Securities accepted by the Fund will be valued, as set forth in the Fund’s prospectus, as of the time of the next determination of NAV after such acceptance. All dividend, subscription, or other rights that are reflected in the market price of accepted securities at the time of valuation become the property of the Fund and must be delivered to the Fund by the investor upon receipt from the issuer. A gain or loss for federal income tax purposes, depending upon the cost of the securities tendered, would be realized by the investor upon the exchange. Investors interested in purchasing fund shares in kind should contact Vanguard.

Redemption of Shares

The redemption price of shares of the Fund is the NAV per share next determined after the redemption request is received in good order, as defined in the Fund’s prospectus.

The Fund may suspend redemption privileges or postpone the date of payment for redeemed shares (1) during any period that the Exchange is closed or trading on the Exchange is restricted as determined by the SEC; (2) during any period when an emergency exists, as defined by the SEC, as a result of which it is not reasonably practicable for the Fund to dispose of securities it owns or to fairly determine the value of its assets; or (3) for such other periods as the SEC may permit.

The Trust has filed a notice of election with the SEC to pay in cash all redemptions requested by any shareholder of record limited in amount during any 90-day period to the lesser of $250,000 or 1% of the net assets of the Fund at the beginning of such period.

B-20

If Vanguard determines that it would be detrimental to the best interests of the remaining shareholders of the Fund to make payment wholly or partly in cash, the Fund may pay the redemption price in whole or in part by a distribution in kind of readily marketable securities held by the Fund in lieu of cash in conformity with applicable rules of the SEC. Investors may incur brokerage charges on the sale of such securities received in payment of redemptions.

The Fund does not charge a redemption fee. Shares redeemed may be worth more or less than what was paid for them, depending on the market value of the securities held by the Fund.

Right to Change Policies

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 Vanguard reasonably believes 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 purchase fee, 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, Vanguard reasonably believes they are deemed to be in the best interest of a fund.

Investing With Vanguard Through Other Firms

The Fund has authorized certain agents to accept on its behalf purchase and redemption orders, and those agents are authorized to designate other intermediaries to accept purchase and redemption orders on the Fund’s behalf (collectively, Authorized Agents). The Fund will be deemed to have received a purchase or redemption order when an Authorized Agent accepts the order in accordance with the Fund’s instructions. In most instances, a customer order that is properly transmitted to an Authorized Agent will be priced at the NAV per share next determined after the order is received by the Authorized Agent.

MANAGEMENT OF THE FUND

Vanguard

The Fund is part of the Vanguard group of investment companies, which consists of more than 170 funds. Through their jointly owned subsidiary, Vanguard, the funds obtain at cost virtually all of their corporate management, administrative, and distribution services. Vanguard also provides investment advisory services on an at-cost basis to several of the Vanguard funds.

Vanguard employs a supporting staff of management and administrative personnel needed to provide the requisite services to the funds and also furnishes the funds with necessary office space, furnishings, and equipment. Each fund pays its share of Vanguard’s total expenses, which are allocated among the funds under methods approved by the board of trustees of each fund. In addition, each fund bears its own direct expenses, such as legal, auditing, and custodial fees.

The funds’ officers are also officers and employees of Vanguard.

Vanguard, Vanguard Marketing Corporation (VMC), the funds, and the funds’ advisors have adopted codes of ethics designed to prevent employees who may have access to nonpublic information about the trading activities of the funds (access persons) from profiting from that information. The codes of ethics permit access persons to invest in securities for their own accounts, including securities that may be held by a fund, but place substantive and procedural restrictions on the trading activities of access persons. For example, the codes of ethics require that access persons receive advance approval for most securities trades to ensure that there is no conflict with the trading activities of the funds.

Vanguard was established and operates under an Amended and Restated Funds’ Service Agreement. The Amended and Restated Funds’ Service Agreement provides that each Vanguard fund may be called upon to invest up to 0.40% of its

B-21

current net assets in Vanguard. The amounts that each fund has invested are adjusted from time to time in order to maintain the proportionate relationship between each fund’s relative net assets and its contribution to Vanguard’s capital.

As of October 31, 2013, the Fund had contributed capital to Vanguard as follows:


	Capital	Percentage of	Percent of
	Contribution	Fund’s Average	Vanguard’s
Vanguard Fund	to Vanguard	Net Assets	Capitalization
Explorer Fund	$1,374,000	0.01%	0.55%

Management. Corporate management and administrative services include (1) executive staff, (2) accounting and financial, (3) legal and regulatory, (4) shareholder account maintenance, (5) monitoring and control of custodian relationships, (6) shareholder reporting, and (7) review and evaluation of advisory and other services provided to the funds by third parties.

Distribution. Vanguard Marketing Corporation, 400 Devon Park Drive A39, Wayne, PA 19087, a wholly owned subsidiary of Vanguard, is the principal underwriter for the funds and in that capacity performs and finances marketing, promotional, and distribution activities (collectively, marketing and distribution activities) that are primarily intended to result in the sale of the funds’ shares. VMC offers shares of each fund for sale on a continuous basis and will use all reasonable efforts in connection with the distribution of shares of the funds. VMC performs marketing and distribution activities at cost in accordance with the conditions of a 1981 SEC exemptive order that permits the Vanguard funds to internalize and jointly finance the marketing, promotion, and distribution of their shares. The funds’ trustees review and approve the marketing and distribution expenses incurred by the funds, including the nature and cost of the activities and the desirability of each fund’s continued participation in the joint arrangement.

To ensure that each fund’s participation in the joint arrangement falls within a reasonable range of fairness, each fund contributes to VMC’s marketing and distribution expenses in accordance with an SEC-approved formula. Under that formula, one half of the marketing and distribution expenses are allocated among the funds based upon their relative net assets. The remaining half of those expenses are allocated among the funds based upon each fund’s sales for the preceding 24 months relative to the total sales of the funds as a group, provided, however, that no fund’s aggregate quarterly rate of contribution for marketing and distribution expenses shall exceed 125% of the average marketing and distribution expense rate for Vanguard and that no fund shall incur annual marketing and distribution expenses in excess of 0.20% of its average month-end net assets. Each fund’s contribution to these marketing and distribution expenses helps to maintain and enhance the attractiveness and viability of the Vanguard complex as a whole, which benefits all of the funds and their shareholders.

VMC’s principal marketing and distribution expenses are for advertising, promotional materials, and marketing personnel.

Other marketing and distribution activities that VMC undertakes on behalf of the funds may include, but are not limited to:

Conducting or publishing Vanguard-generated research and analysis concerning the funds, other investments, the financial markets, or the economy.
Providing views, opinions, advice, or commentary concerning the funds, other investments, the financial markets, or the economy.
Providing analytical, statistical, performance, or other information concerning the funds, other investments, the financial markets, or the economy.

VMC performs most marketing and distribution activities itself. Some activities may be conducted by third parties pursuant to shared marketing arrangements under which VMC agrees to share the costs and performance of marketing and distribution activities in concert with a financial service provider. Financial service providers include, but are not limited to, investment advisors, broker-dealers, financial planners, financial consultants, banks, and insurance companies. Under these cost- and performance-sharing arrangements, VMC may pay or reimburse a financial service provider (or a third party it retains) for marketing and distribution activities that VMC would otherwise perform. VMC’s cost- and performance-sharing arrangements may be established in connection with Vanguard investment products or services offered or provided to or through the financial service providers. VMC’s arrangements for shared marketing and distribution activities may vary among financial service providers, and its payments or reimbursements to financial service providers in connection with shared marketing and distribution activities may be significant. VMC participates in an offshore arrangement established with a third party to provide marketing, promotional, and other services to qualifying Vanguard funds that are distributed in certain foreign countries on a private-placement basis to government-sponsored and other institutional investors. In exchange for such services, the third party receives an annual base (fixed) fee and may also receive discretionary fees or performance adjustments.

In connection with its marketing and distribution activities, VMC may give financial service providers (or their representatives) (1) promotional items of nominal value that display Vanguard’s logo, such as golf balls, shirts, towels, pens, and mouse pads; (2) gifts that do not exceed $100 per person annually and are not preconditioned on achievement of a sales target; (3) an occasional meal, a ticket to a sporting event or the theater, or comparable entertainment that is neither so frequent nor so extensive as to raise any question of propriety and is not preconditioned on achievement of a sales target; and (4) reasonable travel and lodging accommodations to facilitate participation in marketing and distribution activities.

VMC, as a matter of policy, does not pay asset-based fees, sales-based fees, or account-based fees to financial service providers in connection with its marketing and distribution activities for the Vanguard funds. VMC policy also prohibits marketing and distribution activities that are intended, designed, or likely to compromise suitability determinations by, or the fulfillment of any fiduciary duties or other obligations that apply to, financial service providers. Nonetheless, VMC’s marketing and distribution activities are primarily intended to result in the sale of the funds’ shares, and as such, its activities, including shared marketing and distribution activities, may influence participating financial service providers (or their representatives) to recommend, promote, include, or invest in a Vanguard fund or share class. In addition, Vanguard or any of its subsidiaries may retain a financial service provider to provide consulting or other services, and that financial service provider also may provide services to investors. Investors should consider the possibility that any of these activities or relationships may influence a financial service provider’s (or its representatives’) decision to recommend, promote, include, or invest in a Vanguard fund or share class. Each financial service provider should consider its suitability determinations, fiduciary duties, and other legal obligations (or those of its representatives) in connection with any decision to consider, recommend, promote, include, or invest in a Vanguard fund or share class.

The following table describes the expenses of Vanguard and VMC that are incurred by the Fund on an at-cost basis. Amounts captioned “Management and Administrative Expenses” include a fund‘s allocated share of expenses associated with the management, administrative, and transfer agency services Vanguard provides to the funds. Amounts captioned “Marketing and Distribution Expenses” include a fund‘s allocated share of expenses associated with the marketing and distribution activities that VMC conducts on behalf of the Vanguard funds.

As is the case with all mutual funds, transaction costs incurred by the Fund for buying and selling securities are not reflected in the table. Annual Shared Fund Operating Expenses are based on expenses incurred in the fiscal years ended October 31, 2011, 2012, and 2013, and are presented as a percentage of the Fund‘s average month-end net assets.

The Fund’s investment advisors may direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the Fund part of the commissions generated. Such rebates are used solely to reduce the Fund‘s management and administrative expenses and are not reflected in these totals.

Officers and Trustees

Each Vanguard fund is governed by the board of trustees of its trust and a single set of officers. Consistent with the board’s corporate governance principles, the trustees believe that their primary responsibility is oversight of the management of each fund for the benefit of its shareholders, not day-to-day management. The trustees set broad policies for the funds; select investment advisors; monitor fund operations, regulatory compliance, performance, and costs; nominate and select new trustees; and elect fund officers. Vanguard manages the day-to-day operations of the funds under the direction of the board of trustees.

The trustees play an active role, as a full board and at the committee level, in overseeing risk management for the funds. The trustees delegate the day-to-day risk management of the funds to various groups, including portfolio review, investment management, risk management, compliance, legal, fund accounting, and fund financial services. These groups provide the trustees with regular reports regarding investment, valuation, liquidity, and compliance, as well as the risks associated with each. The trustees also oversee risk management for the funds through regular interactions with the funds’ internal and external auditors.

The full board participates in the funds’ risk oversight, in part, through the Vanguard funds’ compliance program, which covers the following broad areas of compliance: investment and other operations; recordkeeping; valuation and pricing; communications and disclosure; reporting and accounting; oversight of service providers; fund governance; and codes of ethics, insider trading controls, and protection of nonpublic information. The program seeks to identify and assess risk through various methods, including through regular interdisciplinary communications between compliance professionals and business personnel who participate on a daily basis in risk management on behalf of the funds. The funds’ chief compliance officer regularly provides reports to the board in writing and in person.

The audit committee of the board, which is composed of all independent trustees, oversees management of financial risks and controls. The audit committee serves as the channel of communication between the independent auditors of the funds and the board with respect to financial statements and financial-reporting processes, systems of internal control, and the audit process. The head of internal audit reports directly to the audit committee and provides reports to the committee in writing and in person on a regular basis. Although the audit committee is responsible for overseeing the management of financial risks, the entire board is regularly informed of these risks through committee reports.

All of the trustees bring to each fund’s board a wealth of executive leadership experience derived from their service as executives (in many cases chief executive officers), board members, and leaders of diverse public operating companies, academic institutions, and other organizations. In determining whether an individual is qualified to serve as a trustee of the funds, the board considers a wide variety of information about the trustee, and multiple factors contribute to the board’s decision. Each trustee is determined to have the experience, skills, and attributes necessary to serve the funds and their shareholders because each trustee demonstrates an exceptional ability to consider complex business and financial matters, evaluate the relative importance and priority of issues, make decisions, and contribute effectively to the deliberations of the board. The board also considers the individual experience of each trustee and determines that the trustee’s professional experience, education, and background contribute to the diversity of perspectives on the board. The business acumen, experience, and objective thinking of the trustees are considered invaluable assets for Vanguard management and, ultimately, the Vanguard funds’ shareholders. The specific roles and experience of each board member that factor into this determination are presented on the following pages. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

All but one of the trustees are independent. The independent trustees designate a lead independent trustee. The lead independent trustee is a spokesperson and principal point of contact for the independent trustees and is responsible for coordinating the activities of the independent trustees, including calling regular executive sessions of the independent trustees; developing the agenda of each meeting together with the chairman; and chairing the meetings of the independent trustees, including the meetings of the audit, compensation, and nominating committees. The board also has two investment committees, which consist of independent trustees and the sole interested trustee.

The independent trustees appoint the chairman of the board. The roles of chairman of the board and chief executive officer currently are held by the same person; as a result, the chairman of the board is an “interested” trustee. The independent trustees generally believe that the Vanguard funds’ chief executive officer is best qualified to serve as chairman and that fund shareholders benefit from this leadership structure through accountability and strong day-to-day leadership.

Board Committees: The Trust‘s board has the following committees:

Audit Committee: This committee oversees the accounting and financial reporting policies, the systems of internal controls, and the independent audits of each fund. All independent trustees serve as members of the committee. The committee held four meetings during the Fund‘s fiscal year ended October 31, 2013.
Compensation Committee: This committee oversees the compensation programs established by each fund for the benefit of its trustees. All independent trustees serve as members of the committee. The committee held six meetings during the Fund‘s fiscal year ended October 31, 2013.
Investment Committees: These committees assist the board in its oversight of investment advisors to the funds and in the review and evaluation of materials relating to the board’s consideration of investment advisory agreements with the funds. Each trustee serves on one of two investment committees. Each investment committee held four meetings during the Fund‘s fiscal year ended October 31, 2013.
Nominating Committee: This committee nominates candidates for election to the board of trustees of each fund. The committee also has the authority to recommend the removal of any trustee. All independent trustees serve as members of the committee. The committee held three meetings during the Fund‘s fiscal year ended October 31, 2013.

The Nominating Committee will consider shareholder recommendations for trustee nominees. Shareholders may send recommendations to Mr. Rankin, chairman of the committee.

B-28

Trustee Compensation

The same individuals serve as trustees of all Vanguard funds and each fund pays a proportionate share of the trustees’ compensation. The funds also employ their officers on a shared basis; however, officers are compensated by Vanguard, not the funds.

Independent Trustees. The funds compensate their independent trustees (i.e., the ones who are not also officers of the funds) in three ways:

The independent trustees receive an annual fee for their service to the funds, which is subject to reduction based on absences from scheduled board meetings.
The independent trustees are reimbursed for the travel and other expenses that they incur in attending board meetings.
Upon retirement (after attaining age 65 and completing five years of service), the independent trustees who began their service prior to January 1, 2001, receive a retirement benefit under a separate account arrangement. As of January 1, 2001, the opening balance of each eligible trustee’s separate account was generally equal to the net present value of the benefits he or she had accrued under the trustees’ former retirement plan. Each eligible trustee’s separate account will be credited annually with interest at a rate of 7.5% until the trustee receives his or her final distribution. Those independent trustees who began their service on or after January 1, 2001, are not eligible to participate in the plan.

“Interested” Trustee. Mr. McNabb serves as trustee but is not paid in this capacity. He is, however, paid in his role as an officer of Vanguard.

Compensation Table. The following table provides compensation details for each of the trustees. We list the amounts paid as compensation and accrued as retirement benefits by the Fund for each trustee. In addition, the table shows the total amount of benefits that we expect each trustee to receive from all Vanguard funds upon retirement and the total amount of compensation paid to each trustee by all Vanguard funds.

Portfolio Holdings Disclosure Policies and Procedures

Introduction

Vanguard and the boards of trustees of the Vanguard funds (Boards) have adopted Portfolio Holdings Disclosure Policies and Procedures (Policies and Procedures) to govern the disclosure of the portfolio holdings of each Vanguard fund. Vanguard and the Boards considered each of the circumstances under which Vanguard fund portfolio holdings may be disclosed to different categories of persons under the Policies and Procedures. Vanguard and the Boards also considered actual and potential material conflicts that could arise in such circumstances between the interests of Vanguard fund shareholders, on the one hand, and those of the fund’s investment advisor, distributor, or any affiliated person of the fund, its investment advisor, or its distributor, on the other. After giving due consideration to such matters and after the exercise of their fiduciary duties and reasonable business judgment, Vanguard and the Boards determined that the Vanguard funds have a legitimate business purpose for disclosing portfolio holdings to the persons described in each of the circumstances set forth in the Policies and Procedures and that the Policies and Procedures are reasonably designed to ensure that disclosure of portfolio holdings and information about portfolio holdings is in the best interests of fund shareholders and appropriately addresses the potential for material conflicts of interest.

The Boards exercise continuing oversight of the disclosure of Vanguard fund portfolio holdings by (1) overseeing the implementation and enforcement of the Policies and Procedures, the Code of Ethics, and the Policies and Procedures Designed to Prevent the Misuse of Inside Information (collectively, the portfolio holdings governing policies) by the chief compliance officer of Vanguard and the Vanguard funds; (2) considering reports and recommendations by the chief compliance officer concerning any material compliance matters (as defined in Rule 38a-1 under the 1940 Act and Rule 206(4)-7 under the Investment Advisers Act of 1940) that may arise in connection with any portfolio holdings governing policies; and (3) considering whether to approve or ratify any amendment to any portfolio holdings governing policies. Vanguard and the Boards reserve the right to amend the Policies and Procedures at any time and from time to time without prior notice at their sole discretion. For purposes of the Policies and Procedures, the term “portfolio holdings” means the equity and debt securities (e.g., stocks and bonds) held by a Vanguard fund and does not mean the cash investments, derivatives, and other investment positions (collectively, other investment positions) held by the fund.

B-30

Online Disclosure of Ten Largest Stock Holdings

Each actively managed Vanguard fund generally will seek to disclose the fund’s ten largest stock portfolio holdings 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 (quarter-end ten largest stock holdings with weightings) online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, 15 calendar days after the end of the calendar quarter. Each Vanguard index fund generally will seek to disclose the fund’s ten largest stock portfolio holdings and the percentage of the fund’s total assets that each of these holdings represents as of the end of the most recent month (month-end ten largest stock holdings with weightings) online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, 15 calendar days after the end of the month. In addition, Vanguard funds generally will seek to disclose the fund’s ten largest stock portfolio holdings and the aggregate percentage of the fund’s total assets (and, for balanced funds, the aggregate percentage of the fund’s equity securities) that these holdings represent as of the end of the most recent month (month-end ten largest stock holdings) online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, 10 business days after the end of the month. Together, the quarter-end and month-end ten largest stock holdings are referred to as the ten largest stock holdings. Online disclosure of the ten largest stock holdings is made to all categories of persons, including individual investors, institutional investors, intermediaries, third-party service providers, rating and ranking organizations, affiliated persons of a Vanguard fund, and all other persons.

Online Disclosure of Complete Portfolio Holdings

Each actively managed Vanguard fund, excluding Vanguard money market funds and Vanguard Market Neutral Fund, generally will seek to disclose the fund’s complete portfolio holdings as of the end of the most recent calendar quarter online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, 30 calendar days after the end of the calendar quarter. In accordance with Rule 2a-7 under the 1940 Act, each of the Vanguard money market funds will disclose the fund’s complete portfolio holdings as of the last business day of the prior month online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, no later than the fifth business day of the current month. The complete portfolio holdings information for money market funds will remain available online for at least six months after the initial posting. Vanguard Market Neutral Fund generally will seek to disclose the Fund’s complete portfolio holdings as of the end of the most recent calendar quarter online at vanguard.com, in the “Portfolio” section of the Fund’s Portfolio & Management page, 60 calendar days after the end of the calendar quarter. Each Vanguard index fund generally will seek to disclose the fund’s complete portfolio holdings as of the end of the most recent month online at vanguard.com, in the “Portfolio” section of the fund’s Portfolio & Management page, 15 calendar days after the end of the month. Online disclosure of complete portfolio holdings is made to all categories of persons, including individual investors, institutional investors, intermediaries, third-party service providers, rating and ranking organizations, affiliated persons of a Vanguard fund, and all other persons. Vanguard’s Portfolio Review Department will review complete portfolio holdings before online disclosure is made and, except with respect to the complete portfolio holdings of the Vanguard money market funds, may withhold any portion of the fund’s complete portfolio holdings from online disclosure when deemed to be in the best interests of the fund after consultation with a Vanguard fund’s investment advisor.

Disclosure of Complete Portfolio Holdings to Service Providers Subject to Confidentiality and Trading Restrictions

Vanguard, for legitimate business purposes, may disclose Vanguard fund complete portfolio holdings at times it deems necessary and appropriate to rating and ranking organizations; financial printers; proxy voting service providers; pricing information vendors; third parties that deliver analytical, statistical, or consulting services; and other third parties that provide services (collectively, Service Providers) to Vanguard, Vanguard subsidiaries, and/or the Vanguard funds. Disclosure of complete portfolio holdings to a Service Provider is conditioned on the Service Provider being subject to a written agreement imposing a duty of confidentiality, including a duty not to trade on the basis of any material nonpublic information.

The frequency with which complete portfolio holdings may be disclosed to a Service Provider, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed to the Service Provider, is determined based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, the risk of harm to the funds and their shareholders, and the legitimate business purposes served by such disclosure. The frequency of disclosure to a Service Provider varies and may be as frequent as daily, with no lag. Disclosure of Vanguard fund complete portfolio holdings by Vanguard to a Service Provider must be authorized by

B-31

a Vanguard fund officer or a Principal in Vanguard’s Portfolio Review or Legal Department. Any disclosure of Vanguard fund complete portfolio holdings to a Service Provider as previously described may also include a list of the other investment positions that make up the fund, such as cash investments and derivatives.

Vanguard fund complete portfolio holdings may be disclosed between and among the following persons (collectively, Affiliates and Fiduciaries) for legitimate business purposes within the scope of their official duties and responsibilities, subject to such persons’ continuing legal duty of confidentiality and legal duty not to trade on the basis of any material nonpublic information, as such duties are imposed under the Code of Ethics, the Policies and Procedures Designed to Prevent the Misuse of Inside Information, by agreement, or under applicable laws, rules, and regulations: (1) persons who are subject to the Code of Ethics or the Policies and Procedures Designed to Prevent the Misuse of Inside Information; (2) an investment advisor, distributor, administrator, transfer agent, or custodian to a Vanguard fund; (3) an accounting firm, an auditing firm, or outside legal counsel retained by Vanguard, a Vanguard subsidiary, or a Vanguard fund; (4) an investment advisor to whom complete portfolio holdings are disclosed for due diligence purposes when the advisor is in merger or acquisition talks with a Vanguard fund’s current advisor; and (5) a newly hired investment advisor or sub-advisor to whom complete portfolio holdings are disclosed prior to the time it commences its duties.

The frequency with which complete portfolio holdings may be disclosed between and among Affiliates and Fiduciaries, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed between and among the Affiliates and Fiduciaries, is determined by such Affiliates and Fiduciaries based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, the risk of harm to the funds and their shareholders, and the legitimate business purposes served by such disclosure. The frequency of disclosure between and among Affiliates and Fiduciaries varies and may be as frequent as daily, with no lag. Any disclosure of Vanguard fund complete portfolio holdings to any Affiliates and Fiduciaries as previously described may also include a list of the other investment positions that make up the fund, such as cash investments and derivatives. Disclosure of Vanguard fund complete portfolio holdings or other investment positions by Vanguard, Vanguard Marketing Corporation, or a Vanguard fund to Affiliates and Fiduciaries must be authorized by a Vanguard fund officer or a Principal of Vanguard.

Currently, Vanguard fund complete portfolio holdings are disclosed to the following Affiliates and Fiduciaries as part of ongoing arrangements that serve legitimate business purposes: Vanguard and each investment advisor, custodian, and independent registered public accounting firm identified in each fund’s Statement of Additional Information.

Disclosure of Portfolio Holdings to Broker-Dealers in the Normal Course of Managing a Fund’s Assets

An investment advisor, administrator, or custodian for a Vanguard fund may, for legitimate business purposes within the scope of its official duties and responsibilities, disclose portfolio holdings (whether partial portfolio holdings or complete portfolio holdings) and other investment positions that make up the fund to one or more broker-dealers during the course of, or in connection with, normal day-to-day securities and derivatives transactions with or through such broker-dealers subject to the broker-dealer’s legal obligation not to use or disclose material nonpublic information concerning the fund’s portfolio holdings, other investment positions, securities transactions, or derivatives transactions without the consent of the fund or its agents. The Vanguard funds have not given their consent to any such use or disclosure and no person or agent of Vanguard is authorized to give such consent except as approved in writing by the Boards of the Vanguard funds. Disclosure of portfolio holdings or other investment positions by Vanguard to broker-dealers must be authorized by a Vanguard fund officer or a Principal of Vanguard.

B-32

Disclosure of Nonmaterial Information

The Policies and Procedures permit Vanguard fund officers, Vanguard fund portfolio managers, and other Vanguard representatives (collectively, Approved Vanguard Representatives) to disclose any views, opinions, judgments, advice, or commentary, or any analytical, statistical, performance, or other information, in connection with or relating to a Vanguard fund or its portfolio holdings and/or other investment positions (collectively, commentary and analysis) or any changes in the portfolio holdings of a Vanguard fund that occurred after the end of the most recent calendar quarter (recent portfolio changes) to any person if (1) such disclosure serves a legitimate business purpose, (2) such disclosure does not effectively result in the disclosure of the complete portfolio holdings of any Vanguard fund (which can be disclosed only in accordance with the Policies and Procedures), and (3) such information does not constitute material nonpublic information. Disclosure of commentary and analysis or recent portfolio changes by Vanguard, Vanguard Marketing Corporation, or a Vanguard fund must be authorized by a Vanguard fund officer or a Principal of Vanguard.

An Approved Vanguard Representative must make a good faith determination whether the information constitutes material nonpublic information, which involves an assessment of the particular facts and circumstances. Vanguard believes that in most cases recent portfolio changes that involve a few or even several securities in a diversified portfolio or commentary and analysis would be immaterial and would not convey any advantage to a recipient in making an investment decision concerning a Vanguard fund. Nonexclusive examples of commentary and analysis about a Vanguard fund include (1) the allocation of the fund’s portfolio holdings and other investment positions among various asset classes, sectors, industries, and countries; (2) the characteristics of the stock and bond components of the fund’s portfolio holdings and other investment positions; (3) the attribution of fund returns by asset class, sector, industry, and country; and (4) the volatility characteristics of the fund. Approved Vanguard Representatives may, at their sole discretion, deny any request for information made by any person, and may do so for any reason or for no reason. Approved Vanguard Representatives include, for purposes of the Policies and Procedures, persons employed by or associated with Vanguard or a subsidiary of Vanguard who have been authorized by Vanguard’s Portfolio Review Department to disclose recent portfolio changes and/or commentary and analysis in accordance with the Policies and Procedures.

Disclosure of Portfolio Holdings Related Information to the Issuer of a Security for Legitimate Business Purposes

Vanguard, at its sole discretion, may disclose portfolio holdings information concerning a security held by one or more Vanguard funds to the issuer of such security if the issuer presents, to the satisfaction of Vanguard’s Fund Financial Services unit, convincing evidence that the issuer has a legitimate business purpose for such information. Disclosure of this information to an issuer is conditioned on the issuer being subject to a written agreement imposing a duty of confidentiality, including a duty not to trade on the basis of any material nonpublic information. The frequency with which portfolio holdings information concerning a security may be disclosed to the issuer of such security, and the length of the lag, if any, between the date of the information and the date on which the information is disclosed to the issuer, is determined based on the facts and circumstances, including, without limitation, the nature of the portfolio holdings information to be disclosed, the risk of harm to the funds and their shareholders, and the legitimate business purposes served by such disclosure. The frequency of disclosure to an issuer cannot be determined in advance of a specific request and will vary based upon the particular facts and circumstances and the legitimate business purposes, but in unusual situations could be as frequent as daily, with no lag. Disclosure of portfolio holdings information concerning a security held by one or more Vanguard funds to the issuer of such security must be authorized by a Vanguard fund officer or a Principal in Vanguard’s Portfolio Review or Legal Department.

Disclosure of Portfolio Holdings as Required by Applicable Law

Vanguard fund portfolio holdings (whether partial portfolio holdings or complete portfolio holdings) and other investment positions that make up a fund shall be disclosed to any person as required by applicable laws, rules, and regulations. Examples of such required disclosure include, but are not limited to, disclosure of Vanguard fund portfolio holdings (1) in a filing or submission with the SEC or another regulatory body, (2) in connection with seeking recovery on defaulted bonds in a federal bankruptcy case, (3) in connection with a lawsuit, or (4) as required by court order. Disclosure of portfolio holdings or other investment positions by Vanguard, Vanguard Marketing Corporation, or a Vanguard fund as required by applicable laws, rules, and regulations must be authorized by a Vanguard fund officer or a Principal of Vanguard.

B-33

Prohibitions on Disclosure of Portfolio Holdings

No person is authorized to disclose Vanguard fund portfolio holdings or other investment positions (whether online at vanguard.com, in writing, by fax, by e-mail, orally, or by other means) except in accordance with the Policies and Procedures. In addition, no person is authorized to make disclosure pursuant to the Policies and Procedures if such disclosure is otherwise unlawful under the antifraud provisions of the federal securities laws (as defined in Rule 38a-1 under the 1940 Act). Furthermore, Vanguard’s management, at its sole discretion, may determine not to disclose portfolio holdings or other investment positions that make up a Vanguard fund to any person who would otherwise be eligible to receive such information under the Policies and Procedures, or may determine to make such disclosures publicly as provided by the Policies and Procedures.

Prohibitions on Receipt of Compensation or Other Consideration

The Policies and Procedures prohibit a Vanguard fund, its investment advisor, and any other person or entity from paying or receiving any compensation or other consideration of any type for the purpose of obtaining disclosure of Vanguard fund portfolio holdings or other investment positions. “Consideration” includes any agreement to maintain assets in the fund or in other investment companies or accounts managed by the investment advisor or by any affiliated person of the investment advisor.

INVESTMENT ADVISORY SERVICES

The Trust currently uses eight investment advisors:

Arrowpoint Asset Management, LLC, provides investment advisory services for a portion of Vanguard Explorer Fund.
Century Capital Management, LLC, provides investment advisory services for a portion of Vanguard Explorer Fund.
Chartwell Investment Partners, Inc., provides investment advisory services for a portion of Vanguard Explorer Fund.
Granahan Investment Management, Inc., provides investment advisory services for a portion of Vanguard Explorer Fund.
Kalmar Investment Advisers provides investment advisory services for a portion of Vanguard Explorer Fund.
Stephens Investment Management Group, LLC, provides investment advisory services for a portion of Vanguard Explorer Fund.
Wellington Management Company, LLP, provides investment advisory services for a portion of Vanguard Explorer Fund.
Vanguard provides investment advisory services for a portion of Vanguard Explorer Fund.

For funds that are advised by independent third-party advisory firms unaffiliated with Vanguard, the board of trustees of each fund hires investment advisory firms, not individual portfolio managers, to provide investment advisory services to such funds. Vanguard negotiates each advisory agreement, which contains advisory fee arrangements, on an arm’s length basis with the advisory firm. Each advisory agreement is reviewed annually by each fund’s board of trustees, taking into account numerous factors, which include, without limitation, the nature, extent, and quality of the services provided; investment performance; and the fair market value of the services provided. Each advisory agreement is between the Trust and the advisory firm, not between the Trust and the portfolio manager. The structure of the advisory fee paid to each unaffiliated investment advisory firm is described in the following sections. In addition, each firm has established policies and procedures designed to address the potential for conflicts of interest. Each firm’s compensation structure and management of potential conflicts of interest is summarized by the advisory firm in the following sections for the fiscal year ended October 31, 2013.

A fund is a party to an investment advisory agreement with each of its independent third-party advisors whereby the advisor manages the investment and reinvestment of the portion of the fund’s assets that the fund’s board of trustees determines to assign to the advisor. In this capacity, each advisor continuously reviews, supervises, and administers the investment program for its portion of the fund’s assets. Hereafter, each portion will be referred to as the advisor’s Portfolio. Each advisor discharges its responsibilities subject to the supervision and oversight of Vanguard’s Portfolio Review Group and the officers and trustees of the fund. Vanguard’s Portfolio Review Group is responsible for recommending changes in a fund’s advisory arrangements to the fund’s board of trustees, including changes in the amount of assets allocated to each advisor and recommendations to hire, terminate, or replace an advisor.

The Fund pays each of its independent third-party investment advisors a base fee plus or minus a performance adjustment. Each base fee, which is paid quarterly, is a percentage of average daily net assets managed by the advisor

B-34

during the most recent fiscal quarter. The base fee has breakpoints, which means that the percentage declines as assets go up. The performance adjustment, also paid quarterly, is based on the cumulative total return of each advisor’s portion of the Fund relative to that of the Russell 2500 Growth Index (for Arrowpoint Partners, Kalmar, SIMG, and Wellington Management), the Russell 2000 Growth Index (for Chartwell), a 50/50 blend of the Russell 2000 Growth Index and the Russell 2500 Growth Index (for Granahan), or a 50/50 blend of the Russell 2500 Index and the Russell 2500 Growth Index (for Century Capital) over the preceding 36-month period (60-month period for Arrowpoint Partners and SIMG). Vanguard provides investment advisory services for a portion of the Fund on an at-cost basis.

Prior to the appointment of Arrowpoint Partners, and during the fiscal years ended October 31, 2011, 2012, and 2013, Vanguard Explorer Fund incurred aggregate investment advisory fees and expenses of approximately $20,200,000 (before a performance-based decrease of $56,000), $19,599,000 (before a performance-based decrease of $2,338,000), and $21,212,000 (before a performance-based decrease of $20,000), respectively.

Of the aggregate fees and expenses previously described, the investment advisory expenses paid to Vanguard for the fiscal year ended October 31, 2013, were approximately $323,000 (representing an effective annual rate of less than 0.01%). The investment advisory fees paid to the remaining advisors for the fiscal year ended October 31, 2013, were $20,869,000 (representing an effective annual rate of approximately 0.21%).

A. Arrowpoint Asset Management, LLC (Arrowpoint Partners)

Arrowpoint Partners, located in Denver, Colorado, is an investment advisory firm founded in 2007.

1. Other Accounts Managed

Chad Meade co-manages a portion of Vanguard Explorer Fund; as of July 31, 2014, the Fund held assets of $XX billion. As of July 31, 2014, Mr. Meade also co-managed two other registered investment companies with total assets of $XX billion (advisory fees not based on account performance) and one other account with total assets of $XX million (advisory fees not based on account performance).

Brian Schaub co-manages a portion of Vanguard Explorer Fund; as of July 31, 2014, the Fund held assets of XX billion. As of July 31, 2014, Mr. Schaub also co-managed two other registered investment companies with total assets of $XX billion (advisory fees not based on account performance) and one other account with total assets of $XX million (advisory fees not based on account performance).

2. Material Conflicts of Interest

Potential conflicts could include a portfolio manager’s knowledge about the size, timing, and possible market impact of a fund’s trades, whereby the portfolio manager could use this information to the advantage or disadvantage of another fund. A fund’s portfolio managers may be able to select or otherwise influence the selection of the brokers and dealers that are used to execute securities transactions for a fund. In addition to executing trades, some brokers and dealers provide managers with brokerage research services, which may result in the payment of higher brokerage fees than might have otherwise been available. These services may be more beneficial to certain funds or accounts than to others. Although the payment of brokerage commissions is subject to the requirement that the portfolio manager determine in good faith that the commissions are reasonable in relation to the value of the brokerage and research services provided to a fund, a portfolio manager’s decision as to the selection of brokers and dealers could potentially yield disproportionate costs and benefits among the individual funds.

A fund’s portfolio managers and analysts may also face other potential conflicts of interest in managing the funds, and the description above is not a complete description of every conflict that could be deemed to exist in managing both the funds and other accounts. In addition, the portfolio managers or analysts may also manage other accounts (including their personal assets or the assets of family members) in their personal capacity. The management of these accounts may also involve certain of the potential conflicts described above. Investment personnel, including the portfolio managers and analysts, are subject to restrictions on engaging in personal securities transactions pursuant to a Code of Ethics adopted by Arrowpoint Partners and the funds. Although the potential for conflicts of interest may exist, the funds and Arrowpoint Partners believe that they have established policies and procedures that seek to minimize potential conflicts of interest and to ensure that the purchase and sale of securities among all managed accounts are fairly and equitably executed and allocated.

B-35

3. Description of Compensation

The portfolio manager’s compensation is a combination of a fixed rate salary and annual bonus. Total compensation is based on a combination of the performance of each fund managed by the portfolio manager against a fund’s benchmark(s) as well as against its relevant peer group. Peer groups may include Lipper Inc; Morningstar, Inc.; and other customized universes of funds managed. Bonus compensation is based on a rolling three-year comparison versus Lipper Small/Mid Cap Peer group and outperformance versus the Russell 2500 Growth Index. Total compensation takes into account the level of assets in the funds, but the primary consideration is the performance of each fund against a benchmark and peer group. All employees share the same group benefits.

4. Ownership of Securities

As of July 31, 2014, Mr. Meade and Mr. Schaub did not own any shares of the Fund.

B. Century Capital Management, LLC (Century Capital)

Century Capital is a Delaware limited liability company. The firm is an independent, employee-owned investment adviser that traces its origins to 1928 and the establishment of Century Shares Trust.

1. Other Accounts Managed

Alexander L. Thorndike manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Thorndike also managed two other registered investment companies with total assets of $630 million and three other accounts with total assets of $89 million (none of which had advisory fees based on account performance).

2. Material Conflicts of Interest

At Century Capital, a portfolio manager may manage multiple accounts for multiple clients. Managing multiple accounts may give rise to potential conflicts of interest including, for example, conflicts related to the allocation of investment opportunities. A portfolio manager may have an incentive to allocate favorable or limited investment opportunities or structure the timing of investments to favor accounts that have a higher advisory fee or a performance fee. Century Capital has adopted and implemented policies and procedures regarding the allocation of trades and brokerage, which it believes address the conflicts associated with managing multiple accounts for multiple clients. These policies and procedures generally require that securities be allocated among clients in a manner that is fair and equitable and consistent with the firm’s fiduciary duty to each client. In addition, Century Capital conducts periodic testing and internal reviews designed to detect favorable treatment of one account over another.

3. Description of Compensation

The portfolio manager’s compensation includes a base salary and discretionary bonus and also may include a performance bonus that is linked to the pre-tax performance of the two Century Funds for which he serves as portfolio manager. The amount of the performance bonus depends on the performance of each fund over a 1-year period relative to the fund’s benchmark (the Russell 1000 Growth Index for Century Shares Trust and the Russell 2000 Growth Index for Century Small Cap Select Fund). The performance bonus typically does not represent a substantial portion of the portfolio manager’s total compensation.

The portfolio manager’s compensation also includes ownership distributions. In general, distributions are based on the class of equity held and the level of ownership interest.

All employees, including the portfolio manager, are eligible to participate in the firm’s 401(k) plan. The firm’s annual contribution to the plan is discretionary and based primarily on the firm’s profitability.

4. Ownership of Securities

As of October 31, 2013, Mr. Thorndike owned shares of the Fund within the $100,001–$500,000 range.

B-36

C. Chartwell Investment Partners, Inc. (Chartwell)

Chartwell is a Pennsylvania corporation and a wholly owned subsidiary of TriState Capital Holdings, Inc. TriState Capital Holdings, Inc., is a registered bank holding company headquartered in Pittsburgh, Pennsylvania.

1. Other Accounts Managed

The management of and investment decisions for the Chartwell Portfolio are made by the Chartwell Growth Group, of which Edward N. Antoian and John A. Heffern are senior members. The Chartwell Growth Group manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion.

Mr. Antoian co-manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Antoian also co-managed one other registered investment company with total assets of $21.3 million (advisory fee not based on account performance), two other pooled investment vehicles with total assets of $187.7 million (advisory fees not based on account performance), and 14 other accounts with total assets of $579.5 million (advisory fee based on account performance for one of these accounts with total assets of $39.8 million).

Mr. Heffern co-manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Heffern also co-managed two other registered investment companies with total assets of $43.6 million (advisory fee not based on account performance), one other pooled investment vehicle with total assets of $700,000 (advisory fees not based on account performance), and 14 other accounts with total assets of $579.5 million (advisory fee based on account performance for one of these accounts with total assets of $39.8 million).

2. Material Conflicts of Interest

With the exception of the two hedge funds managed by Mr. Antoian (discussed in this section), all portfolios are managed in like-style; except for possible client-imposed portfolio restrictions, there are no material conflicts of interest that may arise in connection with simultaneous management of the Chartwell Portfolio and such other accounts. In the allocation of investment opportunities, unless prohibited by client guidelines, trade orders for multiple portfolios in a given investment product are generally “batched” or placed as an aggregated order for execution. Placing an aggregate order may enable Chartwell to obtain more favorable execution and net price for the combined order. All portfolios included in an aggregated trade are allocated the same average price per share. If in fact there are multiple orders on the trade blotter for the same security that cannot be aggregated because of client restrictions, a simple rotational system is implemented.

Proprietary Accounts: Certain new investment products developed begin as incubator funds and, in some cases, are funded by internal officers, directors, partners, and portfolio managers’ personal assets. These new products are traded exactly the same as regular client accounts, except that they do not participate in IPOs. Such accounts are not favored over any other account. The Compliance Group monitors all activity in these accounts regularly. No investment or performance fees are received by the investors nor the firm. Once sufficient client assets are raised in the product, the incubator is closed. Chartwell’s Code of Ethics requires disclosure of any Private Placement investments by all employees including firm incubator funds.

Hedge Funds: Mr. Antoian manages two hedge funds. There is generally a limited amount of overlap of investments between one hedge fund and all other accounts previously listed that are managed by the Chartwell Growth Group (client accounts). Investment opportunities that are appropriate for both the client accounts and the hedge fund are allocated on a pro-rata basis and no one account is favored over another when participating in the same trade. When investment opportunities are of a limited nature (such as IPOs), shares are allocated on a pro-rata basis for all accounts for which the investment is appropriate; if an allocation from the broker is too small to satisfy a 0.05% position in the participating accounts, a rotational system is deployed. The holdings of the hedge fund and all client accounts, as well as all IPO allocations, are reviewed by the Compliance Group to ensure that controls are working properly. The other hedge fund managed by Mr. Antoian is a “fund of funds” that invests in other hedge funds; therefore there is no overlap of investments between this fund and all other accounts.

Other rules to prevent conflicts of interest: No portfolio manager shall initiate a short sale in an investment account when a registered fund or other investment account either holds, or intends to acquire, a long position in the security. If an investment account has an existing short position in a security that is subsequently purchased as a long position in any

B-37

other client account, the portfolio manager is prohibited from initiating further short sales and any purchases of the security shall be allocated in a fair and equitable manner in accordance with the firm’s trade allocation policies.

3. Description of Compensation

The compensation paid to a Chartwell portfolio manager consists of base salary, annual bonus, ownership distribution (if applicable based on ownership status), and an annual profit-sharing contribution to the firm’s retirement plan. A portfolio manager’s base salary is determined by Chartwell’s Compensation Committee and is reviewed at least annually. A portfolio manager’s experience, historical performance, and role in firm or product team management are the primary considerations in determining the base salary. Industry benchmarking is utilized by the Compensation Committee on an annual basis.

Annual bonuses are determined by the Compensation Committee based on a number of factors. The primary factor is a performance-based compensation schedule that is applied to all accounts managed by a portfolio manager within a particular investment product and is not specific to any one account. The bonus is calibrated based on the gross composite performance of such accounts over one- and three-year periods versus the appropriate benchmark (the Russell 2000 Growth Index) and peer-group rankings. Portfolio construction, sector and security weighting, and performance are reviewed by the Compliance Committee and Compensation Committee to prevent a manager from taking undue risks. Additional factors used to determine the annual bonus include the portfolio manager’s contribution as an analyst, product team management, and contribution to the strategic planning and development of the investment group as well as the firm.

Ownership distributions are paid to an employee based on the employee’s level and type of ownership interest(s). There are currently three types of equity: (1) straight limited partnership interests, (2) Class B share interests, and (3) phantom stock interests. In all cases, the annual ownership distributions are paid to employees based on their respective percentage equity interest(s) multiplied by total net cash distributions paid during the year.

Chartwell also provides a profit-sharing and a 401(k) plan for all employees. The annual profit-sharing contribution and/or matching contribution from Chartwell is discretionary and based solely on the profitability of the firm.

Chartwell’s compensation structure is very competitive with respect to their peers in the industry. Chartwell strives to provide a working environment that fosters creativity as well as ownership enthusiasm.

4. Ownership of Securities

As of October 31, 2013, Mr. Antoian and Mr. Heffern did not own any shares of the Fund.

D. Granahan Investment Management, Inc. (Granahan)

Granahan is a Massachusetts corporation.

1. Other Accounts Managed

Gary C. Hatton, Jane M. White, Jennifer M. Pawloski, and John V. Schneider co-manage a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Hatton, Ms. White, Ms. Pawloski, and Mr. Schneider also co-managed two other registered investment companies with total assets of $1.2 billion (advisory fee based on account performance for one of these accounts with total assets of $869.6 million), and Mr. Hatton also managed two other pooled investment vehicles with total assets of $107.9 million (advisory fees not based on account performance).

2. Material Conflicts of Interest

The portfolio management team responsible for managing the Granahan Portfolio has similar responsibilities to other clients of Granahan. The firm has established policies and procedures to address the potential conflicts of interest inherent in managing portfolios for multiple clients. These policies and procedures are designed to prevent and detect favorable treatment of one account over another and include policies for allocating trades equitably across multiple accounts, monitoring the composition of client portfolios to ensure that each reflects the investment profile of that client, and reviewing the performance of accounts of similar styles. Additionally, each employee of Granahan is bound by

B-38

its Code of Ethics, which establishes policies and procedures designed to ensure that clients’ interests are placed before those of an individual or the firm.

3. Description of Compensation

The Granahan Portfolio is managed by the portfolio management team of Gary C. Hatton, Jane M. White, Jennifer M. Pawloski, and John V. Schneider. The portfolio managers’ compensation is made up of a base salary plus a performance bonus. Base salary for portfolio managers varies depending on qualitative and quantitative factors such as salary levels in the industry, experience, length of employment, and the nature and number of other duties for which he or she has responsibility. The performance bonus is based on a number of factors including the one- and three-year returns, before management fees and taxes, of each account managed relative to its benchmark (an equal combination of the Russell 2500 Growth Index and the Russell 2000 Growth Index for the Granahan Portfolio); the one- and three-year returns, before management fees and taxes, of each account managed relative to the benchmark sector for which that manager has responsibility; and the value of the assets managed by that manager. Additionally, members of the portfolio management team receive a share of Granahan profits either in the form of dividends for shareholders or via the company’s profit-sharing program for nonshareholders.

4. Ownership of Securities

As of October 31, 2013, Mr. Hatton and Ms. White each owned shares of the Fund within the $10,001–$50,000 range; Ms. Pawloski and Mr. Schneider did not own shares of the Fund.

E. Kalmar Investment Advisers (Kalmar)

Kalmar, a business trust registered in the state of Delaware, is a research-driven investment firm that is entirely focused on the management of “growth-with-value” smaller-cap equity portfolios and is owned in its entirety by active Kalmar employees. Kalmar is a sister company of Kalmar Investments Inc., the firm’s separate account management arm, which was founded in 1982.

1. Other Accounts Managed

Ford B. Draper, Jr., and Dana F. Walker, along with Kalmar’s investment team, co-manage a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Draper and Mr. Walker also co-managed two other registered investment companies with total assets of $1.8 billion (advisory fee based on account performance for one of these accounts with total assets of $996 million) and 281 other accounts with total assets of $1.2 billion (advisory fees not based on account performance).

2. Material Conflicts of Interest

Kalmar’s policy from the firm’s inception is to avoid conflicts of interest by neither favoring nor disfavoring any account systematically versus any other. Accordingly, on a best efforts basis, investment opportunities are shared among all accounts of the same market-cap size class as evenhandedly as possible over time. Kalmar has three market-cap size classes of accounts under management: small-cap, smid-cap, and mid-cap. Kalmar’s investment strategy is applied uniformly, and individual securities are owned as uniformly as possible by all accounts within a size class, except for those clients with particular investment restrictions or guidelines. In those cases, the same strategy is applied except for elimination of restricted securities.

3. Description of Compensation

Kalmar seeks to maintain a competitive and incentivized compensation program to attract and retain outstanding, high-caliber investment professionals. Therefore, Kalmar closely links the investment professionals’ compensation to their particular contributions to client returns and to the attainment of the performance goals of Kalmar’s “growth-with-value” investment philosophy, in which the Kalmar Portfolio participates. Portfolio managers receive base salaries, incentive bonus opportunities, benefits packages, and opportunities (if invited by Kalmar’s board of directors) to purchase equity in Kalmar. Portfolio manager compensation is reviewed and modified each year as appropriate to reflect changes in the marketplace, as well as to adjust the factors used to determine bonuses, in order to promote good sustained client performance, including the Kalmar Portfolio’s performance.

B-39

Fixed Based Salary: In setting portfolio manager base salaries, Kalmar seeks to be competitive in light of each person’s experience, tenure, contribution, and responsibilities.

Annual Bonus: Each portfolio manager is eligible to receive an annual cash bonus which has quantitative and nonquantitative components. The quantitative component, which generally represents 60–70% of the bonus, is based on the specific contribution of the individual’s research ideas to the pre-tax success of managed portfolios in absolute and index-relative terms for short-term (1 year) and long-term (2–5 year) periods.

The nonquantitative component is based on an evaluation of the individual’s contribution to Kalmar’s team-oriented research and portfolio management process and of his or her other contributions to client satisfaction, client communication, and the overall success of the firm over the past year. For purposes of illustration, examples of factors weighed in this evaluation are (1) maintenance of insightful knowledge and opinions on companies owned by the portfolio; (2) generation and development of new investment ideas, including the quality of security analysis and identification of appreciation catalysts; (3) ability and willingness to develop and share ideas and contribute to idea deliberation on a team basis; and (4) contribution to investment strategy, buy and sell discipline, and the overall performance results of the portfolios managed by the investment team, as well as the productive functioning of the team.

Benefits Package: All employees, including portfolio managers, participate in Kalmar’s benefits package, which includes a 401(k) plan with a contribution by Kalmar and a profit-sharing plan based on the overall success of the firm. The opportunity for equity ownership in Kalmar is open to all key, high-contributing employees of the firm from all professional disciplines, solely at the discretion and invitation of Kalmar’s board of directors. Such ownership is purchased from the firm rather than awarded as a bonus. Mr. Draper is the lead partner in Kalmar. This equity ownership, coupled with the other competitive and incentivizing ingredients in Kalmar’s compensation package, is intended to link the partner’s compensation directly, plus indirectly but effectively, to client success and performance outcomes.

4. Ownership of Securities

As of October 31, 2013, Mr. Draper and Mr. Walker did not own any shares of the Fund.

F. Stephens Investment Management Group, LLC (SIMG)

SIMG, located in Little Rock, Arkansas, is a subsidiary of Stephens Investments Holdings, a privately held and family owned company.

1. Other Accounts Managed

Ryan E. Crane manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Crane also managed two other registered investment companies with total assets of $739 million (advisory fees not based on account performance) and 50 other accounts with total assets of $2 billion (advisory fees based on account performance for two of these accounts with total assets of $506 million).

2. Material Conflicts of Interest

SIMG manages a number of separate accounts and two other registered investment companies that utilize similar investment strategies as the SIMG Portfolio. Most of these separate accounts are charged an asset-based fee by SIMG, but two of the accounts are charged a performance fee. The firm has established policies and procedures to address the potential conflicts of interest inherent in managing portfolios for multiple clients. These policies and procedures are designed to prevent and detect favorable treatment of one account over another and include policies for allocating trades equitably across multiple accounts, monitoring the composition of client portfolios to ensure that each reflects the investment profile of the client, and reviewing the performance of accounts of similar styles. Additionally, each employee of SIMG is bound by its Code of Ethics, which establishes policies and procedures designed to ensure the clients’ interests are placed before those of an individual or the firm.

3. Description of Compensation

All SIMG Portfolio Managers receive compensation in the form of a fixed salary and performance bonus. The performance bonus can represent a significant portion of the total compensation. The amount of a Portfolio Manager’s bonus is a function of SIMG products’ asset weighted 1-, 3-, and 5-year performance relative to the appropriate benchmark and peer group. Portfolio Managers with sector specific responsibilities receive a portion of their bonus

B-40

based on performance contribution and attribution analysis based on each individual’s performance within their respective sectors. Mr. Crane’s bonus as team leader is more a function of the product’s performance (in the manner described above) and less sensitive to individual stock picks. His bonus also has a subjective portion that is related in part to SIMG’s level of profitability. Each member of the portfolio management team is a shareholder of Class B shares of SIMG and receives a portion of the overall net profits of SIMG. Performance is measured over the most recent calendar year.

4. Ownership of Securities

As of October 31, 2013, Mr. Crane did not own any shares of the Fund.

G. Wellington Management Company, LLP (Wellington Management)

Wellington Management is a Massachusetts limited liability partnership with principal offices at 280 Congress Street, Boston, MA 02210. As of July 1, 2013, the firm is owned by 131 partners, all fully active in the business of the firm. Wellington Management is a professional investment counseling firm that provides investment services to investment companies, employee benefit plans, endowments, foundations, and other institutions. Wellington Management and its predecessor organizations have provided investment advisory services for over 80 years. Kenneth L. Abrams, Senior Vice President and Equity Portfolio Manager of Wellington Management, has served as a portfolio manager of the Wellington Management Portfolio since 1994.

1. Other Accounts Managed

Mr. Abrams manages a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Abrams also managed two other registered investment companies with total assets of $358.1 million (advisory fees not based on account performance), six other pooled investment vehicles with total assets of $1.4 billion (advisory fees not based on account performance), and eight other accounts with total assets of $1.6 billion (advisory fee based on account performance for one of these accounts with total assets of $24.7 million).

Daniel J. Fitzpatrick serves as associate portfolio manager for a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Fitzpatrick also managed two other registered investment companies with total assets of $358.1 million (advisory fees not based on account performance), three other pooled investment vehicles with total assets of $710.7 million (advisory fees not based on account performance), and five other accounts with total assets of $1.2 billion (advisory fee based on account performance for one of these accounts with total assets of $24.7 million).

2. Material Conflicts of Interest

Individual investment professionals at Wellington Management manage multiple accounts for multiple clients. These accounts may include mutual funds, separate accounts (assets managed on behalf of institutions, such as pension funds, insurance companies, foundations, or separately managed account programs sponsored by financial intermediaries), bank common trust accounts, and hedge funds. The Wellington Management Portfolio’s managers listed in the prospectus, who are primarily responsible for the day-to-day management of the Wellington Management Portfolio (the Portfolio Managers), generally manage accounts in several different investment styles. These accounts may have investment objectives, strategies, time horizons, tax considerations, and risk profiles that differ from those of the Fund. The Portfolio Managers make investment decisions for each account, including the Wellington Management Portfolio, based on the investment objectives, policies, practices, benchmarks, cash flows, tax, and other relevant investment considerations applicable to that account. Consequently, the Portfolio Managers may purchase or sell securities, including IPOs, for one account and not another account, and the performance of securities purchased for one account may vary from the performance of securities purchased for other accounts. Alternatively, these accounts may be managed in a similar fashion to the Wellington Management Portfolio, and thus the accounts may have similar—and in some cases nearly identical—objectives, strategies, and/or holdings to those of the Wellington Management Portfolio.

A Portfolio Manager or other investment professional at Wellington Management may place transactions on behalf of other accounts that are directly or indirectly contrary to investment decisions made on behalf of the Wellington Management Portfolio or make investment decisions that are similar to those made for the Wellington Management Portfolio, both of which have the potential to adversely impact the Wellington Management Portfolio depending on market conditions. For example, an investment professional may purchase a security in one account while appropriately

B-41

selling that same security in another account. Similarly, a Portfolio Manager may purchase the same security for the Wellington Management Portfolio and one or more other accounts at or about the same time. In those instances the other accounts will have access to their respective holdings prior to the public disclosure of the Wellington Management Portfolio’s holdings. In addition, some of these accounts have fee structures, including performance fees, which are or have the potential to be higher, in some cases significantly higher, than the fees Wellington Management receives for managing the Wellington Management Portfolio. Mr. Abrams and Mr. Fitzpatrick also manage accounts that pay performance allocations to Wellington Management or its affiliates. Because incentive payments paid by Wellington Management to the Portfolio Managers are tied to revenues earned by Wellington Management and, where noted, to the performance achieved by the manager in each account, the incentives associated with any given account may be significantly higher or lower than those associated with other accounts managed by a given Portfolio Manager. Finally, the Portfolio Managers may hold shares or investments in the other pooled investment vehicles and/or other accounts previously identified.

Wellington Management’s goal is to meet its fiduciary obligation to treat all clients fairly and provide high-quality investment services to all of its clients. Wellington Management has adopted and implemented policies and procedures, including brokerage and trade allocation policies and procedures, that it believes address the conflicts associated with managing multiple accounts for multiple clients. In addition, Wellington Management monitors a variety of areas, including compliance with primary account guidelines, the allocation of IPOs, and compliance with the firm’s Code of Ethics, and places additional investment restrictions on investment professionals who manage hedge funds and certain other accounts. Furthermore, senior investment and business personnel at Wellington Management periodically review the performance of Wellington Management’s investment professionals. Although Wellington Management does not track the time an investment professional spends on a single account, Wellington Management does periodically assess whether an investment professional has adequate time and resources to effectively manage the investment professional’s various client mandates.

3. Description of Compensation

Wellington Management receives a fee based on the assets under management of the Wellington Management Portfolio as set forth in the Investment Advisory Agreement between Wellington Management and the Trust on behalf of the Fund. Wellington Management pays its investment professionals out of its total revenues, including the advisory fees earned with respect to the Wellington Management Portfolio. The following information relates to fiscal year ended October 31, 2013.

Wellington Management’s compensation structure is designed to attract and retain high-caliber investment professionals necessary to deliver high-quality investment management services to its clients. Wellington Management’s compensation of the named Portfolio Managers includes a base salary and incentive components. The base salary for each Portfolio Manager who is a partner of Wellington Management is generally a fixed amount that is determined by the Managing Partners of the firm.

Each Portfolio Manager is eligible to receive an incentive payment based on the revenues earned by Wellington Management from the Wellington Management Portfolio and generally each other account managed by the Portfolio Manager. Each Portfolio Manager’s incentive payment relating to the Wellington Management Portfolio is linked to the net pre-tax performance of the Wellington Management Portfolio managed by the Portfolio Managers compared to the Russell 2500 Growth Index over one- and three-year periods, with an emphasis on three-year results. In 2012, Wellington Management began placing increased emphasis on long-term performance and is phasing in five-year performance comparison periods. Wellington Management applies similar incentive compensation structures (although the benchmarks or peer groups, time periods, and rates may differ) to other accounts managed by the Portfolio Managers, including accounts with performance fees.

Portfolio-based incentives across all accounts managed by an investment professional can, and typically do, represent a significant portion of an investment professional’s overall compensation; incentive compensation varies significantly by individual and can vary significantly from year to year. The Portfolio Managers may also be eligible for bonus payments based on their overall contribution to Wellington Management’s business operations. Senior management at Wellington Management may reward individuals as it deems appropriate based on other factors. Each partner of Wellington Management is eligible to participate in a partner-funded tax-qualified retirement plan, the contributions to which are made pursuant to an actuarial formula. Mr. Abrams is a partner of the firm.

B-42

4. Ownership of Securities

As of October 31, 2013, Mr. Abrams owned shares of the Fund exceeding $1 million. As of October 31, 2013, Mr. Fitzpatrick owned shares of the Fund in the $500,001–$1,000,000 range.

H. Vanguard

Vanguard, through its Equity Investment Group, provides investment advisory services on an at-cost basis for a portion of Vanguard Explorer Fund. The compensation and other expenses of Vanguard’s advisory staff are allocated among the funds utilizing Vanguard’s advisory services.

1. Other Accounts Managed

James D. Troyer, James P. Stetler, and Michael R. Roach co-manage a portion of Vanguard Explorer Fund; as of October 31, 2013, the Fund held assets of $12.1 billion. As of October 31, 2013, Mr. Troyer, Mr. Stetler, and Mr. Roach also co-managed all or a portion of 13 other registered investment companies with total assets of $98 billion and four other pooled investment vehicles with total assets of $85.5 million (none of which had advisory fees based on account performance).

2. Material Conflicts of Interest

At Vanguard, individual portfolio managers may manage multiple accounts for multiple clients. In addition to mutual funds, these accounts may include separate accounts, collective trusts, and offshore funds. Managing multiple funds or accounts may give rise to potential conflicts of interest including, for example, conflicts among investment strategies and conflicts in the allocation of investment opportunities. Vanguard manages potential conflicts between funds or accounts through allocation policies and procedures, internal review processes, and oversight by trustees and independent third parties. Vanguard has developed trade allocation procedures and controls to ensure that no one client, regardless of type, is intentionally favored at the expense of another. Allocation policies are designed to address potential conflicts in situations where two or more funds or accounts participate in investment decisions involving the same securities.

3. Description of Compensation

All Vanguard portfolio managers are Vanguard employees. This section describes the compensation of the Vanguard employees who manage Vanguard mutual funds. As of October 31, 2013, a Vanguard portfolio manager’s compensation generally consists of base salary, bonus, and payments under Vanguard’s long-term incentive compensation program. In addition, portfolio managers are eligible for the standard retirement benefits and health and welfare benefits available to all Vanguard employees. Also, certain portfolio managers may be eligible for additional retirement benefits under several supplemental retirement plans that Vanguard adopted in the 1980s to restore dollar-for-dollar the benefits of management employees that had been cut back solely as a result of tax law changes. These plans are structured to provide the same retirement benefits as the standard retirement plans.

In the case of portfolio managers responsible for managing multiple Vanguard funds or accounts, the method used to determine their compensation is the same for all funds and investment accounts. A portfolio manager’s base salary is determined by the manager’s experience and performance in the role, taking into account the ongoing compensation benchmark analyses performed by Vanguard’s Human Resources Department. A portfolio manager’s base salary is generally a fixed amount that may change as a result of an annual review, upon assumption of new duties, or in response to a market adjustment of the position.

A portfolio manager’s bonus is determined by a number of factors. One factor is gross, pre-tax performance of the fund relative to expectations for how the fund should have performed, given the fund’s investment objective, policies, strategies, and limitations, and the market environment during the measurement period. This performance factor is not based on the amount of assets held in the fund’s portfolio. For the portion of Vanguard Explorer Fund managed by Vanguard, the performance factor depends on how successfully the portfolio manager outperforms the Russell 2500 Growth Index and maintains the risk parameters of the Fund over a three-year period. Additional factors include the portfolio manager’s contributions to the investment management functions within the sub-asset class, contributions to the development of other investment professionals and supporting staff, and overall contributions to strategic planning and decisions for the investment group. The target bonus is expressed as a percentage of base salary. The actual bonus

B-43

paid may be more or less than the target bonus, based on how well the manager satisfies the objectives previously described. The bonus is paid on an annual basis.

Under the long-term incentive compensation program, all full-time employees receive a payment from Vanguard’s long-term incentive compensation plan based on their years of service, job level, and, if applicable, management responsibilities. Each year, Vanguard’s independent directors determine the amount of the long-term incentive compensation award for that year based on the investment performance of the Vanguard funds relative to competitors and Vanguard’s operating efficiencies in providing services to the Vanguard funds.

4. Ownership of Securities

Vanguard employees, including portfolio managers, allocate their investments among the various Vanguard funds based on their own individual investment needs and goals. Vanguard employees, as a group, invest a sizable portion of their personal assets in Vanguard funds. As of October 31, 2013, Vanguard employees collectively invested more than $4.1 billion in Vanguard funds. F. William McNabb III, Chairman of the Board, Chief Executive Officer, and President of Vanguard and the Vanguard funds, invests substantially all of his personal financial assets in Vanguard funds.

As of October 31, 2013, Mr. Roach owned shares of Vanguard Explorer Fund within the $50,001–$100,000 range. Mr. Troyer and Mr. Stetler did not own any shares of the Fund.

Duration and Termination of Investment Advisory Agreements

The current investment advisory agreements with Century Capital, Chartwell, Granahan, Kalmar, and Wellington Management are renewable for successive one-year periods, only if (1) each renewal is approved by a vote of the Fund’s board of trustees, including the affirmative votes of a majority of the trustees who are not parties to the agreement or “interested persons” (as defined in the 1940 Act) of any such party, cast in person at a meeting called for the purpose of considering such approval or (2) each renewal is specifically approved by a vote of a majority of the Fund’s outstanding voting securities. An agreement is automatically terminated if assigned and may be terminated without penalty at any time either (1) by vote of the board of trustees of the Fund upon thirty (30) days’ written notice to the advisor (sixty (60) days’ written notice for Chartwell), (2) by a vote of a majority of the Fund’s outstanding voting securities upon 30 days’ written notice to the advisor (60 days’ written notice for Chartwell), or (3) by the advisor upon ninety (90) days’ written notice to the Fund.

The initial investment advisory agreements with both Arrowpoint Partners and SIMG are binding for a two-year period. At the end of that time, the agreements will become renewable for successive one-year periods, subject to the above conditions.

Vanguard provides at-cost investment advisory services to the Fund pursuant to the terms of the Fifth Amended and Restated Funds’ Service Agreement. This agreement will continue in full force and effect until terminated or amended by mutual agreement of the Vanguard funds and Vanguard.

PORTFOLIO TRANSACTIONS

The advisor decides which securities to buy and sell on behalf of the Fund and then selects the brokers or dealers that will execute the trades on an agency basis or the dealers with whom the trades will be effected on a principal basis. For each trade, the advisor must select a broker-dealer that it believes will provide “best execution.” Best execution does not necessarily mean paying the lowest spread or commission rate available. In seeking best execution, the SEC has said that an advisor should consider the full range of a broker-dealer’s services. The factors considered by the advisor in seeking best execution include, but are not limited to, the broker-dealer’s execution capability, clearance and settlement services, commission rate, trading expertise, willingness and ability to commit capital, ability to provide anonymity, financial responsibility, reputation and integrity, responsiveness, access to underwritten offerings and secondary markets, and access to company management, as well as the value of any research provided by the broker-dealer. In assessing which broker-dealer can provide best execution for a particular trade, the advisor also may consider the timing and size of the order and available liquidity and current market conditions. Subject to applicable legal requirements, the advisor may select a broker based partly on brokerage or research services provided to the advisor and its clients, including the Fund. The advisor may cause the Fund to pay a higher commission than other brokers would charge if the advisor determines in good faith that the amount of the commission is reasonable in relation to the value of services

B-44

provided. The advisor also may receive brokerage or research services from broker-dealers that are provided at no charge in recognition of the volume of trades directed to the broker. To the extent research services or products may be a factor in selecting brokers, services and products may include written research reports analyzing performance or securities, discussions with research analysts, meetings with corporate executives to obtain oral reports on company performance, market data, and other products and services that will assist the advisor in its investment decision-making process. The research services provided by brokers through which the Fund effects securities transactions may be used by the advisor in servicing all of its accounts, and some of the services may not be used by the advisor in connection with the Fund.

During the fiscal years ended October 31, 2011, 2012, and 2013, the Fund paid the following approximate amounts in brokerage commissions:


Vanguard Fund	2011	2012	2013
Explorer Fund	$15,573,000	$10,732,000	$11,776,000

Some securities that are considered for investment by the Fund may also be appropriate for other Vanguard funds or for other clients served by the advisors. If such securities are compatible with the investment policies of the Fund and one or more of an advisor’s other clients and are considered for purchase or sale at or about the same time, then transactions in such securities may be aggregated by the advisor, and the purchased securities or sale proceeds may be allocated among the participating Vanguard funds and the other participating clients of the advisor in a manner deemed equitable by the advisor. Although there may be no specified formula for allocating such transactions, the allocation methods used, and the results of such allocations, will be subject to periodic review by the Fund‘s board of trustees.

The ability of Vanguard and external advisors to purchase or dispose of investments in regulated industries, the derivatives markets, and certain international markets, or to exercise rights on behalf of the Fund, may be restricted or impaired because of limitations on the aggregate level of investment unless regulatory or corporate consents are obtained. As a result, Vanguard and external advisors on behalf of the Fund may be required to limit purchases, sell existing investments, or otherwise restrict or limit the exercise of shareholder rights by the Fund, including voting rights.

As of October 31, 2013, the Fund held securities of its “regular brokers or dealers,” as that term is defined in Rule 10b-1 of the 1940 Act, as follows:


Regular Broker or Dealer (or Parent)	Aggregate Holdings
Deutsche Bank Securities Inc.	$40,900,000

PROXY VOTING GUIDELINES

The Board of Trustees (the Board) of each Vanguard fund that invests in stocks has adopted proxy voting procedures and guidelines to govern proxy voting by the fund. The Board has delegated responsibility for monitoring proxy voting activities to the Proxy Oversight Committee (the Committee), made up of senior officers of Vanguard and subject to the operating procedures and guidelines described below. The Committee reports directly to the Board. Vanguard is subject to these procedures and guidelines to the extent that they call for Vanguard to administer the voting process and implement the resulting voting decisions, and for these purposes the guidelines have been approved by the Board of Directors of Vanguard.

The overarching objective in voting is simple: to support proposals and director nominees that maximize the value of a fund’s investments—and those of fund shareholders—over the long term. Although the goal is simple, the proposals the funds receive are varied and frequently complex. As such, the guidelines adopted by the Board provide a rigorous framework for assessing each proposal. Under the guidelines, each proposal must be evaluated on its merits, based on the particular facts and circumstances as presented.

For ease of reference, the procedures and guidelines often refer to all funds. However, our processes and practices seek to ensure that proxy voting decisions are suitable for individual funds. For most proxy proposals, particularly those involving corporate governance, the evaluation will result in the same position being taken across all of the funds and the funds voting as a block. In some cases, however, a fund may vote differently, depending upon the nature and objective of the fund, the composition of its portfolio, and other factors.

B-45

The guidelines do not permit the Board to delegate voting responsibility to a third party that does not serve as a fiduciary for the funds. Because many factors bear on each decision, the guidelines incorporate factors the Committee should consider in each voting decision. A fund may refrain from voting some or all of its shares or vote in a particular way if doing so would be in the fund’s and its shareholders’ best interests. These circumstances may arise, for example, if the expected cost of voting exceeds the expected benefits of voting, if exercising the vote would result in the imposition of trading or other restrictions, or if a fund (or all Vanguard funds in the aggregate) were to own more than the permissible maximum percentage of a company’s stock (as determined by the company’s governing documents or by applicable law, regulation, or regulatory agreement).

In evaluating proxy proposals, we consider information from many sources, including, but not limited to, the investment advisor for the fund, the management or shareholders of a company presenting a proposal, and independent proxy research services. We will give substantial weight to the recommendations of the company’s board, absent guidelines or other specific facts that would support a vote against management. In all cases, however, the ultimate decision rests with the members of the Committee, who are accountable to the fund’s Board.

While serving as a framework, the following guidelines cannot contemplate all possible proposals with which a fund may be presented. In the absence of a specific guideline for a particular proposal (e.g., in the case of a transactional issue or contested proxy), the Committee will evaluate the issue and cast the fund’s vote in a manner that, in the Committee’s view, will maximize the value of the fund’s investment, subject to the individual circumstances of the fund.

I. The Board of Directors

A. Election of directors

Good governance starts with a majority-independent board, whose key committees are made up entirely of independent directors. As such, companies should attest to the independence of directors who serve on the Compensation, Nominating, and Audit committees. In any instance in which a director is not categorically independent, the basis for the independence determination should be clearly explained in the proxy statement.

Although the funds will generally support the board’s nominees, the following factors will be taken into account in determining each fund’s vote:


Factors For Approval	Factors Against Approval
Nominated slate results in board made up of a majority of	Nominated slate results in board made up of a majority of
independent directors.	non-independent directors.
All members of Audit, Nominating, and Compensation	Audit, Nominating, and/or Compensation committees include
committees are independent of management.	non-independent members.
	Incumbent board member failed to attend at least 75% of meetings
	in the previous year.
	Actions of committee(s) on which nominee serves are inconsistent with
	other guidelines (e.g., excessive equity grants, substantial non-audit fees,
	lack of board independence).


B. Contested director elections

In the case of contested board elections, we will evaluate the nominees’ qualifications, the performance of the incumbent board, and the rationale behind the dissidents’ campaign, to determine the outcome that we believe will maximize shareholder value.

C. Classified boards

The funds will generally support proposals to declassify existing boards (whether proposed by management or shareholders), and will block efforts by companies to adopt classified board structures in which only part of the board is elected each year.

II. Approval of Independent Auditors

The relationship between the company and its auditors should be limited primarily to the audit, although it may include certain closely related activities that do not, in the aggregate, raise any appearance of impaired independence. The funds

B-46

will generally support management’s recommendation for the ratification of the auditor, except in instances in which audit and audit-related fees make up less than 50% of the total fees paid by the company to the audit firm. We will evaluate on a case-by-case basis instances in which the audit firm has a substantial non-audit relationship with the company (regardless of its size relative to the audit fee) to determine whether independence has been compromised.

III. Compensation Issues

A. Stock-based compensation plans

Appropriately designed stock-based compensation plans, administered by an independent committee of the board and approved by shareholders, can be an effective way to align the interests of long-term shareholders with the interests of management, employees, and directors. The funds oppose plans that substantially dilute their ownership interest in the company, provide participants with excessive awards, or have inherently objectionable structural features.

An independent compensation committee should have significant latitude to deliver varied compensation to motivate the company’s employees. However, we will evaluate compensation proposals in the context of several factors (a company’s industry, market capitalization, competitors for talent, etc.) to determine whether a particular plan or proposal balances the perspectives of employees and the company’s other shareholders. We will evaluate each proposal on a case-by-case basis, taking all material facts and circumstances into account.

The following factors will be among those considered in evaluating these proposals:


Factors For Approval	Factors Against Approval
Company requires senior executives to hold a minimum amount	Total potential dilution (including all stock-based plans) exceeds 15% of
of company stock (frequently expressed as a multiple of salary).	shares outstanding.
Company requires stock acquired through equity awards to be	Annual equity grants have exceeded 2% of shares outstanding.

(indicating that the plan is very broad-based).
Stock-based compensation is clearly used as a substitute for	Plan contains automatic share replenishment (evergreen) feature.
cash in delivering market-competitive total pay.

B. Bonus plans

Bonus plans, which must be periodically submitted for shareholder approval to qualify for deductibility under Section 162(m) of the IRC, should have clearly defined performance criteria and maximum awards expressed in dollars. Bonus plans with awards that are excessive, in both absolute terms and relative to a comparative group, generally will not be supported.

C. Employee stock purchase plans

The funds will generally support the use of employee stock purchase plans to increase company stock ownership by employees, provided that shares purchased under the plan are acquired for no less than 85% of their market value and that shares reserved under the plan amount to less than 5% of the outstanding shares.

D. Advisory votes on executive compensation (Say on Pay)

In addition to proposals on specific equity or bonus plans, the funds are required to cast advisory votes approving many companies’ overall executive compensation plans (so-called Say on Pay votes). In evaluating these proposals, we consider a number of factors, including the amount of compensation that is at risk, the amount of equity-based compensation that is linked to the company’s performance, and the level of compensation as compared to industry peers. The funds will generally support pay programs that demonstrate effective linkage between pay and performance over time and that provide compensation opportunities that are competitive relative to industry peers. On the other hand, pay programs in which significant compensation is guaranteed or insufficiently linked to performance will be less likely to earn our support.

B-47

E. Executive severance agreements (golden parachutes)

Although executives’ incentives for continued employment should be more significant than severance benefits, there are instances—particularly in the event of a change in control—in which severance arrangements may be appropriate. Severance benefits payable upon a change of control AND an executive’s termination (so-called “double trigger” plans) are generally acceptable to the extent that benefits paid do not exceed three times salary and bonus. Arrangements in which the benefits exceed three times salary and bonus should be justified and submitted for shareholder approval. We do not generally support guaranteed severance absent a change in control or arrangements that do not require the termination of the executive (so-called “single trigger” plans).

IV. Corporate Structure and Shareholder Rights

The exercise of shareholder rights, in proportion to economic ownership, is a fundamental privilege of stock ownership that should not be unnecessarily limited. Such limits may be placed on shareholders’ ability to act by corporate charter or by-law provisions, or by the adoption of certain takeover provisions. In general, the market for corporate control should be allowed to function without undue interference from these artificial barriers.

The funds’ positions on a number of the most commonly presented issues in this area are as follows:

A. Shareholder rights plans (poison pills)

A company’s adoption of a so-called poison pill effectively limits a potential acquirer’s ability to buy a controlling interest

without the approval of the target’s board of directors. Such a plan, in conjunction with other takeover defenses, may serve to entrench incumbent management and directors. However, in other cases, a poison pill may force a suitor to negotiate with the board and result in the payment of a higher acquisition premium.

In general, shareholders should be afforded the opportunity to approve shareholder rights plans within a year of their adoption. This provides the board with the ability to put a poison pill in place for legitimate defensive purposes, subject to subsequent approval by shareholders. In evaluating the approval of proposed shareholder rights plans, we will consider the following factors:


Factors For Approval	Factors Against Approval
Plan is relatively short-term (3-5 years).	Plan is long term (>5 years).
Plan requires shareholder approval for renewal.	Renewal of plan is automatic or does not require shareholder approval.
Plan incorporates review by a committee of independent	Board with limited independence.
directors at least every three years (so-called TIDE provisions).
Ownership trigger is reasonable (15-20%).	Ownership trigger is less than 15%.
Highly independent, non-classified board.	Classified board.
Plan includes permitted-bid/qualified-offer feature (chewable
pill) that mandates a shareholder vote in certain situations.

B. Cumulative voting

The funds are generally opposed to cumulative voting under the premise that it allows shareholders a voice in director elections that is disproportionate to their economic investment in the corporation.

C. Supermajority vote requirements

The funds support shareholders’ ability to approve or reject matters presented for a vote based on a simple majority. Accordingly, the funds will support proposals to remove supermajority requirements and oppose proposals to impose them.

D. Right to call meetings and act by written consent

The funds support shareholders’ right to call special meetings of the board (for good cause and with ample representation) and to act by written consent. The funds will generally vote for proposals to grant these rights to shareholders and against proposals to abridge them.

B-48

E. Confidential voting

The integrity of the voting process is enhanced substantially when shareholders (both institutions and individuals) can vote without fear of coercion or retribution based on their votes. As such, the funds support proposals to provide confidential voting.

F. Dual classes of stock

We are opposed to dual class capitalization structures that provide disparate voting rights to different groups of shareholders with similar economic investments. We will oppose the creation of separate classes with different voting rights and will support the dissolution of such classes.

V. Corporate and Social Policy Issues

Proposals in this category, initiated primarily by shareholders, typically request that the company disclose or amend certain business practices. The Board generally believes that these are “ordinary business matters” that are primarily the responsibility of management and should be evaluated and approved solely by the corporation’s board of directors. Often, proposals may address concerns with which the Board philosophically agrees, but absent a compelling economic impact on shareholder value (e.g., proposals to require expensing of stock options), the funds will typically abstain from voting on these proposals. This reflects the belief that regardless of our philosophical perspective on the issue, these decisions should be the province of company management unless they have a significant, tangible impact on the value of a fund’s investment and management is not responsive to the matter.

VI. Voting in Foreign Markets

Corporate governance standards, disclosure requirements, and voting mechanics vary greatly among the markets outside the United States in which the funds may invest. Each fund’s votes will be used, where applicable, to advocate for improvements in governance and disclosure by each fund’s portfolio companies. We will evaluate issues presented to shareholders for each fund’s foreign holdings in the context with the guidelines described above, as well as local market standards and best practices. The funds will cast their votes in a manner believed to be philosophically consistent with these guidelines, while taking into account differing practices by market. In addition, there may be instances in which the funds elect not to vote, as described below.

Many foreign markets require that securities be “blocked” or reregistered to vote at a company’s meeting. Absent an issue of compelling economic importance, we will generally not subject the fund to the loss of liquidity imposed by these requirements.

The costs of voting (e.g., custodian fees, vote agency fees) in foreign markets may be substantially higher than for U.S. holdings. As such, the fund may limit its voting on foreign holdings in instances in which the issues presented are unlikely to have a material impact on shareholder value.

VII. Voting Shares of a Company that has an Ownership Limitation

Certain companies have provisions in their governing documents that restrict stock ownership in excess of a specified limit. Typically, these ownership restrictions are included in the governing documents of real estate investment trusts, but may be included in other companies’ governing documents.

A company’s governing documents normally allow the company to grant a waiver of these ownership limits, which would allow a fund (or all Vanguard-advised funds) to exceed the stated ownership limit. Sometimes a company will grant a waiver without restriction. From time to time, a company may grant a waiver only if a fund (or funds) agrees to not vote the company’s shares in excess of the normal specified limit. In such a circumstance, a fund may refrain from voting shares if owning the shares beyond the company’s specified limit is in the best interests of the fund and its shareholders.

In addition, applicable law may require prior regulatory approval to permit ownership of certain regulated issuer’s voting securities above certain limits or may impose other restrictions on owners of more than a certain percentage of a regulated issuer’s voting shares. The Board has authorized the funds to vote shares above these limits in the same proportion as votes cast by the issuer’s entire shareholder base (i.e., mirror vote) or to refrain from voting excess shares if mirror voting is not practicable. For example, rules administered by the Board of Governors of the Federal Reserve

B-49

System (the “FRB”) generally require that a person seeking to own more than 10% of a bank regulated by the FRB seek prior approval. Vanguard has obtained regulatory approval that allows Vanguard funds to own up to 15% of a class of a bank’s outstanding voting shares without seeking prior regulatory approval, provided the funds’ shares in excess of 10% are mirror voted or not voted at all.

These ownership limits may be applied at the individual fund level, across all Vanguard-advised funds, or across all Vanguard funds, regardless of whether they are advised by Vanguard.

VIII. Voting on a Fund’s Holdings of Other Vanguard Funds

Certain Vanguard funds (owner funds) may, from time to time, own shares of other Vanguard funds (underlying funds). If an underlying fund submits a matter to a vote of its shareholders, votes for and against such matters on behalf of the owner funds will be cast in the same proportion as the votes of the other shareholders in the underlying fund.

IX. The Proxy Voting Group

The Board has delegated the day-to-day operations of the funds’ proxy voting process to the Proxy Voting Group, which the Committee oversees. Although most votes will be determined, subject to the individual circumstances of each fund, by reference to the guidelines as separately adopted by each of the funds, there may be circumstances when the Proxy Voting Group will refer proxy issues to the Committee for consideration. In addition, at any time, the Board has the authority to vote proxies, when, at the Board’s or the Committee’s discretion, such action is warranted.

The Proxy Voting Group performs the following functions: (1) managing proxy voting vendors; (2) reconciling share positions; (3) analyzing proxy proposals using factors described in the guidelines; (4) determining and addressing potential or actual conflicts of interest that may be presented by a particular proxy; and (5) voting proxies. The Proxy Voting Group also prepares periodic and special reports to the Board, and any proposed amendments to the procedures and guidelines.

X. The Proxy Oversight Committee

The Board, including a majority of the independent trustees, appoints the members of the Committee who are senior officers of Vanguard.

The Committee does not include anyone whose primary duties include external client relationship management or sales. This clear separation between the proxy voting and client relationship functions is intended to eliminate any potential conflict of interest in the proxy voting process. In the unlikely event that a member of the Committee believes he or she might have a conflict of interest regarding a proxy vote, that member must recuse himself or herself from the committee meeting at which the matter is addressed, and not participate in the voting decision.

The Committee works with the Proxy Voting Group to provide reports and other guidance to the Board regarding proxy voting by the funds. The Committee has an obligation to conduct its meetings and exercise its decision-making authority subject to the fiduciary standards of good faith, fairness, and Vanguard’s Code of Ethics. The Committee shall authorize proxy votes that the Committee determines, at its sole discretion, to be in the best interests of each fund’s shareholders. In determining how to apply the guidelines to a particular factual situation, the Committee may not take into account any interest that would conflict with the interest of fund shareholders in maximizing the value of their investments.

The Board may review these procedures and guidelines and modify them from time to time. The procedures and guidelines are available on Vanguard’s website at vanguard.com.

You may obtain a free copy of a report that details how the funds voted the proxies relating to the portfolio securities held by the funds for the prior 12-month period ended June 30 by logging on to Vanguard’s website at vanguard.com or the SEC’s website at www.sec.gov.

Item 30. Indemnification

The Registrant’s organizational documents contain provisions indemnifying Trustees and officers against liability incurred in their official capacities. Article VII, Section 2 of the Amended and Restated Agreement and Declaration of Trust provides that the Registrant may indemnify and hold harmless each and every Trustee and officer from and against any and all claims, demands, costs, losses, expenses, and damages whatsoever arising out of or related to the performance of his or her duties as a Trustee or officer. Article VI of the By-Laws generally provides that the Registrant shall indemnify its Trustees and officers from any liability arising out of their past or present service in that capacity. Among other things, this provision excludes any liability arising by reason of willful misfeasance, bad faith, gross negligence, or the reckless disregard of the duties involved in the conduct of the Trustee’s or officer’s office with the Registrant.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted for directors, officers, or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is therefore unenforceable.
