Investment Objective

Vanguard S&P 500 Value Index Fund seeks to track the performance of a benchmark index that measures the investment return of large-capitalization value stocks in the United States.

The following table describe s the fees and expenses you may pay if you buy and hold ETF Shares of Vanguard S&P 500 Value Index Fund.


Shareholder Fees
(Fees paid directly from your investment)

Example

The following example is intended to help you compare the cost of investing in ETF Shares of Vanguard S&P 500 Value Index Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in S&P 500 Value ETF. This example assumes that S&P 500 Value ETF Shares provide a return of 5% a year and that operating expenses match our estimates. 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
$•	$•

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

Portfolio Turnover

The fund has no operating history and therefore has no portfolio turnover information.

Primary Investment Strategy

The Fund employs a “passive management”—or indexing—investment approach designed to track the performance of the S&P 500 Value Index, which represents the value companies of the S&P 500 Index. The Index is broadly diversified and measures the performance of value stocks of large U.S. companies. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

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

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

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

Because ETF Shares are traded on an exchange, they are subject to additional risks:

• S&P 500 Value ETF Shares are listed for trading on • and can be bought and sold on the secondary market at market prices. Although it is expected that the market price of an S&P 500 Value ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy S&P 500 Value ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

• Although S&P 500 Value ETF Shares are listed for trading on •, it is possible that an active trading market may not be maintained.

• Trading of S&P 500 Value ETF Shares on • may be halted if • officials deem such action appropriate, if S&P 500 Value ETF Shares are delisted from •, or if there is an activation of “circuit breakers” (a rule that requires a halt in trading for a specific period of time when market prices decline by a specified percentage during the course of a trading day).

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 Fund began operations on •, 2010, so performance information is not yet available.

The Fund employs a “passive management”—or indexing—investment approach designed to track the performance of the S&P SmallCap 600 Value Index, which represents the value companies of the S&P SmallCap 600 Index. The Index is broadly diversified and measures the performance of value stocks of small U.S. companies. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

Because ETF Shares are traded on an exchange, they are subject to additional risks:

• S&P Small-Cap 600 Value ETF Shares are listed for trading on • and can be bought and sold on the secondary market at market prices. Although it is expected that the market price of an S&P Small-Cap 600 Value ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy S&P Small-Cap 600 Value ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

• Although S&P Small-Cap 600 Value ETF Shares are listed for trading on •, it is possible that an active trading market may not be maintained.

• Trading of S&P Small-Cap 600 Value ETF Shares on • may be halted if • officials deem such action appropriate, if S&P Small-Cap 600 Value ETF Shares are delisted from •, or if there is an activation of “circuit breakers” (a rule that requires a halt in

trading for a specific period of time when market prices decline by a specified percentage during the course of a trading day).

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.

Investing in Vanguard ETF ^® Shares

What Are Vanguard ETF Shares?

Vanguard ETF Shares are an exchange-traded class of shares issued by certain Vanguard mutual funds. ETF Shares represent an interest in the portfolio of stocks or bonds held by the issuing fund. The following ETF Shares are offered through this prospectus:


Fund	ETF Shares	Seeks to Track
Vanguard S&P 500 Value	Vanguard S&P 500 Value ETF	Large-cap value stocks
Index Fund
Vanguard S&P 500 Growth	Vanguard S&P 500 Growth ETF	Large-cap growth stocks

Value Index Fund	Value ETF
Vanguard S&P Small-Cap 600	Vanguard S&P Small-Cap 600	Small-cap growth stocks
Growth Index Fund	Growth ETF

The Funds offer two conventional classes of shares. This prospectus, however, relates only to ETF Shares.

How Are Vanguard ETF Shares Different From Conventional Mutual Fund Shares?

Conventional mutual fund shares are bought from and redeemed with the issuing fund for cash at the net asset value (NAV), typically calculated once a day. ETF Shares, by contrast, cannot be purchased from or redeemed with the issuing fund by an individual investor.

An organized secondary trading market is expected to exist for ETF Shares, unlike conventional mutual fund shares, because ETF Shares are listed for trading on a national securities exchange. Investors can purchase and sell ETF Shares on the secondary market through a broker. Secondary-market transactions occur not at NAV, but at market prices that change throughout the day, based on the supply of, and demand for, ETF Shares and on changes in the prices of the fund’s portfolio holdings.

The market price of a fund’s ETF Shares typically will differ somewhat from the NAV of those shares. The difference between market price and NAV is expected to be small

most of the time, but in times of extreme market volatility the difference may become significant.

How Do I Buy and Sell Vanguard ETF Shares?

Retail investors can purchase ETF Shares on the open market through a broker. When you buy or sell ETF Shares, your broker may charge a commission. You will also incur the cost of the “bid-asked spread,” which is the difference between the price a dealer will pay for a security and the somewhat higher price at which the dealer will sell the same security. In addition, because open-market transactions occur at market prices, you may pay more or less than NAV when you buy ETF Shares, and receive more or less than NAV when you sell those shares.

Your ownership of ETF Shares will be shown on the records of the broker through which you hold the shares. Vanguard will not have any record of your ownership. Your account information will be maintained by your broker, which will provide you with account statements, confirmations of your purchases and sales of ETF Shares, and tax information. Your broker also will be responsible for distributing income and capital gains distributions and for ensuring that you receive shareholder reports and other communications from the fund whose ETF Shares you own. You will receive other services (e.g., dividend reinvestment and average cost information) only if your broker offers these services.

More on the Funds

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

Turnover Rate

Although the Funds normally seek to invest for the long term, each Fund may sell securities regardless of how long they have been held. Generally, an index fund sells securities only in response to redemption requests or to adjust the number of shares held to reflect a change in the fund’s target index. Turnover rates for mid-cap and small-cap stock index funds tend to be higher than for large-cap index funds (although still relatively low, compared with actively managed stock funds) because the indexes they track are the most likely to change as a result of companies merging, growing, or failing.

Dividends, Capital Gains, and Taxes

Fund Distributions

Each 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

Plain Talk About Distributions

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

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

A sale or exchange of Fund shares is a taxable event. This means that you may have
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.

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 Statement of Additional Information relates to all Funds exept Vanguard Admiral Treasury Money Market Fund. A separate Statement of Additional Information (dated December 23, 2009; revised April 9, 2010), which relates to Vanguard Admiral Treasury Money Market Fund, can be obtained free of charge by contacting Vanguard (800-662-7447). 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.

Throughout this document, any references to “class” apply only to the extent a Fund issues multiple classes.

Organization

The Trust was organized as a Maryland corporation in 1992 and was reorganized as a Delaware statutory trust in May 1998. The Trust is registered with the United States Securities and Exchange Commission (the SEC) under the Investment Company Act of 1940 (the 1940 Act) as an open-end, diversified management investment company. Each series (Fund) of the Trust is classified as a diversified company as defined in the 1940 Act.

Service Providers

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

Characteristics of the Funds’ Shares

Restrictions on Holding or Disposing of Shares. There are no restrictions on the right of shareholders to retain or dispose of a Fund’s shares, other than those described in the Fund’s current prospectus and elsewhere in this Statement of Additional Information or the possible future termination of the Fund or a share class. Each 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, each Fund and share class 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 a Fund generally will not be personally liable for payment of the Fund’s debts. Some

B-2

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 a Fund are entitled to receive any dividends or other distributions declared by the Fund for each such class. No shares of a 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.

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 a 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 a Fund’s net assets, to change any fundamental policy of a Fund, and to enter into certain merger transactions. Unless otherwise required by applicable law, shareholders of a 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 a 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 Funds‘ shares.

Conversion Rights. Fund shareholders may convert their shares into another class of shares of the same Fund upon the satisfaction of any then applicable eligibility requirements. ETF Shares cannot be converted into conventional shares of a fund. For additional information about the conversion rights applicable to ETF Shares, please see “Information About the ETF Share Class.” There are no conversion rights associated with the Admiral Treasury Money Market Fund.

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

Sinking Fund Provisions. The Funds have no sinking fund provisions.

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

Tax Status of the Funds

Each Fund expects to qualify each year 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, each Fund must comply with certain requirements. If a Fund fails to meet these requirements in any taxable 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, a 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 each 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 Funds are not eligible for the dividends-received deduction.

B-3

FUNDAMENTAL POLICIES

Each Fund is subject to the following fundamental 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 . Each 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 . Each 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.

Industry Concentration. Each Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry, except as may be necessary to approximate the composition of its target index.

Loans . Each 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.

Real Estate . Each 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 . Each 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 . Each 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 Act (the 1933 Act), in connection with the purchase and sale of portfolio securities.

Compliance with the fundamental policies set forth above 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 Funds from having an ownership interest in Vanguard. As a part owner of Vanguard, each 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 Funds” for more information.

INVESTMENT STRATEGIES AND NONFUNDAMENTAL POLICIES

Some of the investment strategies and policies described below and in each Fund’s prospectus set forth percentage limitations on a 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. 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 each Fund’s investment strategies and policies set forth in the prospectus. With respect to the different investments discussed below, a Fund may acquire such investments to the extent consistent with its investment strategies and policies.

80% Policy. Under normal circumstances, each Fund will invest at least 80% of its assets in the stocks that make up its target index. In applying this 80% policy, assets will include net assets and borrowings for investment purposes.

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

B-4

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 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 “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 (1) maintains an offsetting financial position; (2) 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 (3) 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 for other purposes.

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.

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

B-5

price may be as volatile as that of common stock. Because both interest rate 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 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 voluntary redemptions by holders) and replaced with newly issued convertibles 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.

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 are generally designed for use in securities markets outside the United States. Although the two types of depositary receipt facilities (unsponsored or sponsored) 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 non-objection 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 non-cash 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 that is 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. 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

B-6

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, risk management, seeking to stay fully invested, seeking to reduce transaction costs, seeking to simulate an investment in equity or debt securities or other investments, 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, and for other purposes. 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.

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

B-7

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 the ETF’s shares may trade at a discount to their net asset value; (2) an active trading market for an ETF’s shares may not develop or be maintained; or (3) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

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. Depositary receipts are securities that are listed on exchanges or quoted in OTC markets in one country but represent shares of issuers domiciled in another country. 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 is a risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of the transaction, resulting in a loss to the fund. Securities of foreign issuers are generally less liquid than securities of comparable U.S. issuers. 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 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 taxes against dividend and interest income from foreign securities. Although in some countries a portion of these taxes is recoverable by the fund, the non-recovered portion of foreign withholding taxes will reduce the income received from the companies making up a fund.

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 tends to increase when the value of the U.S. dollar falls against such currency (as discussed below, 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, and by currency restrictions, exchange control regulation, currency devaluations, and political and economic developments.

B-8

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 of a “senior security” by a fund for purposes 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 because the market for the tracking currency is more liquid or more efficient. 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.

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 monies 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 foreign currency forward 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 foreign currency forward contracts are privately negotiated transactions, there can be no assurance that a fund will have flexibility to roll-over a foreign currency forward 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 frequent or 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 of a “senior security” by a fund for purposes of the 1940 Act, and 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 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 described above in the case of futures contracts. A futures option transaction will not be considered to constitute the issuance of a “senior security” by a fund for purposes of the 1940 Act, and 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.”

B-10

Each fund intends to comply with Rule 4.5 of the Commodity Futures Trading Commission, under which a mutual fund is conditionally excluded from the definition of the term “commodity pool operator.” A fund will only enter into futures contracts and futures options that are standardized and traded on a U.S. or foreign exchange, board of trade, or similar entity, or 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) to 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. 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 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 the 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

B-11

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 (1) to deliver the underlying security upon payment of the exercise price (in the case of a call option) or (2) 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 of a “senior security” by a fund for purposes of the 1940 Act, and 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.”

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 interest 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 interests and related interests. 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. This 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.

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 non-cumulative, 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.

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, broker, or dealer, and simultaneously agrees to resell such security to the seller 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 in the ordinary course of business within seven business days at approximately the value at which they are being carried on a fund’s books. The SEC generally limits aggregate holdings of illiquid securities by a mutual fund to 15% of its net assets (10% 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) 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 on a daily basis, 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.

B-13

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 of a “senior security” by a fund, and 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.

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 receive 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 of 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.

Swap Agreements. A swap agreement is a derivative. A swap agreement 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, 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

B-14

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.

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 cheap) 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 of a “senior security” by a fund, and 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, in particular OTC swaps, 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 swaps market is a relatively new market and is largely unregulated. It is possible that developments in the swaps market, including potential government regulation, could adversely affect a fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

Tax Matters — Federal Tax Treatment of Futures Contracts. A fund is required for federal income tax purposes to recognize for each taxable year its net unrealized gains and losses on certain futures contracts as of the end of the year as well as those 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

B-15

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.

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 loans of securities, gains from the sale of securities or of foreign currencies, or other income derived with respect to the fund’s business of investing in securities or currencies. It is anticipated that any net gain recognized on futures contracts will be considered qualifying income for purposes of the 90% requirement.

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. Transactions. Special rules govern the federal income tax treatment of certain transactions denominated in a currency other than the U.S. dollar or determined by reference to the value of one or more currencies other than the U.S. dollar. The types of transactions covered by the special rules include the following: (1) the acquisition of, or becoming the obligor under, a bond or other debt instrument (including, to the extent provided in Treasury regulations, preferred stock); (2) the accruing of certain trade receivables and payables; and (3) the entering into or acquisition of any forward contract, futures contract, option, or similar financial instrument if such instrument is not marked-to-market. The disposition of a currency other than the U.S. dollar by a taxpayer whose functional currency is the U.S. dollar is also treated as a transaction subject to the special currency rules. 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 Treasury Department 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 Treasury regulations) will be integrated and treated as a single transaction or otherwise treated consistently for purposes of the IRC. 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 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 the special currency rules described within this policy.

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 foreign taxes paid, and thereby allow shareholders to take a deduction or, if they meet certain holding period requirements, a tax credit on their tax returns. If shareholders do not meet the holding period requirements, they may still be entitled to a deduction for certain gains that were actually distributed by the fund.

Tax Matters —Tax Considerations for Non-U.S. Investors . U.S. withholding and estate taxes may apply to any investments made by non-U.S. investors in Vanguard funds. The American Jobs Creation Act of 2004, as extended by the Emergency Economic Stabilization Act of 2008, provides relief from U.S. withholding tax for certain properly designated distributions made with respect to a fund’s taxable year beginning prior to 2010, assuming the investor provides tax documentation certifying non-U.S. status. The relief does not by its terms apply to a fund’s taxable year beginning in or after 2010 unless so extended by Congress. The 2008 Act also provides a partial exemption from U.S. estate tax for fund shares held by the estate of a non-U.S. decedent who dies before January 1, 2010.

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

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 after the close of regular trading on the New York Stock Exchange (the Exchange), generally 4 p.m., Eastern time. NAV per share for the Funds is computed by dividing the total assets, minus liabilities, allocated to each share class by the number of Fund shares outstanding for that class.

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 each 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 (Other than ETF Shares)

The purchase price of shares of each Fund is the NAV per share next determined after the purchase request is received in good order, as defined in the Fund’s prospectus. Note that a purchase fee may apply, as described in the prospectus.

Exchange of Securities for Shares of a Fund. In certain circumstances, shares of a Fund may be purchased “in kind” (i.e., in exchange for securities, rather than for cash). The securities tendered as part of an in-kind purchase must be included in the Index tracked by the Fund and must have a total market value of $1 million or more. In addition, each position must have a market value of $10,000 or more. Such securities also must be liquid securities that are not restricted as to transfer and have a value that is readily ascertainable as evidenced by a listing on the American Stock Exchange, the New York Stock Exchange, or Nasdaq. 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 net asset value after such acceptance. Shares of a Fund are issued at net asset value determined as of the same time. 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

B-17

delivered to the Fund by the investor upon receipt from the issuer. A gain or loss for federal income tax purposes would be realized by the investor upon the exchange, depending upon the cost of the securities tendered.

A Fund will not accept securities in exchange for its shares unless: (1) such securities are, at the time of the exchange, eligible to be held by the Fund; (2) the transaction will not cause the Fund’s weightings to become imbalanced with respect to the weightings of the securities included in the corresponding Index; (3) the investor represents and agrees that all securities offered to the Fund are not subject to any restrictions upon their sale by the Fund under the 1933 Act, or otherwise; (4) such securities are traded in an unrelated transaction with a quoted sales price on the same day the exchange valuation is made; (5) the quoted sales price used as a basis of valuation is representative (e.g., one that does not involve a trade of substantial size that artificially influences the price of the security); and (6) the value of any such security being exchanged will not exceed 5% of the Fund’s net assets immediately prior to the transaction.

Investors interested in purchasing fund shares in kind should contact Vanguard.

Redemption of Shares (Other than ETF Shares)

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

Each 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; and (3) for such other periods as the SEC may permit.

Each 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 a Fund at the beginning of such period.

If Vanguard determines that it would be detrimental to the best interests of the remaining shareholders of a 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 Funds do 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 we reasonably believe a fraudulent transaction may occur or has occurred; (4) temporarily freeze any account and/or suspend account services upon initial notification to Vanguard of the death of the shareholder until Vanguard receives required documentation in good order; (5) alter, impose, discontinue, or waive any redemption fee, account service fee, or other fees charged to a group of shareholders; and (6) redeem an account or suspend account privileges, without the owner’s permission to do so, in cases of threatening conduct or activity Vanguard believes to be suspicious, fraudulent, or illegal. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, we reasonably believe they are deemed to be in the best interest of a fund.

Investing With Vanguard Through Other Firms

Each 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). A 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

B-18

is properly transmitted to an Authorized Agent will be priced at the Fund’s NAV next determined after the order is received by the Authorized Agent.

MANAGEMENT OF THE FUNDS

Vanguard

Each Fund is part of the Vanguard group of investment companies, which consists of more than 160 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 custodian fees.

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

Vanguard, Vanguard Marketing Corporation (VMC), the funds’ advisors, and the funds 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 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 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 as follows: (1) each Vanguard fund may be called upon to invest up to 0.40% of its current net assets in Vanguard, and (2) there is no other limitation on the dollar amount that each Vanguard fund may contribute to Vanguard’s capitalization. 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.

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 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 is 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 1% of its average month-end net assets. As of August 31, 2009, none of the Vanguard funds’ allocated share of VMC’s marketing and distribution expenses was greater than 0.03% of the fund’s 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.

B-19

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;
Providing administrative services in connection with investments in the funds or other investments, including, but not limited to, shareholder services, recordkeeping services, and educational services;
Providing products or services that assist investors or financial service providers (as defined below) in the investment decision-making process;
Providing promotional discounts, commission-free trading, fee waivers, and other benefits to clients of Vanguard Brokerage Services ^® who maintain qualifying investments in the funds; and
Sponsoring, jointly sponsoring, financially supporting, or participating in conferences, programs, seminars, presentations, meetings, or other events involving fund shareholders, financial service providers, or others concerning the funds, other investments, the financial markets, or the economy, such as industry conferences, prospecting trips, due diligence visits, training or education meetings, and sales presentations.

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 does not participate in the offshore arrangement Vanguard has established for qualifying Vanguard funds to be distributed in certain foreign countries on a private-placement basis to government-sponsored and other institutional investors through a third-party “asesor de inversiones” (investment advisor), which includes incentive-based remuneration.

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.

B-20

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 code 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 below. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482.

All but one of the trustees is 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 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. The independent turstees generally believe that the Vanguard funds’ chief executive offier 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 and Vanguard. All independent trustees serve as members of the committee.
Compensation Committee: This committee oversees the compensation programs established by each fund and Vanguard for the benefit of their employees, officers, and trustees/directors. All independent trustees serve as members of the committee.
Nominating Committee: This committee nominates candidates for election to Vanguard’s board of directors and the board of trustees of each fund (collectively, the Vanguard boards). The committee also has the authority to recommend the removal of any director or trustee from the Vanguard boards. All independent trustees serve as members of the committee.

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

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:

B-24

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

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.

Online Disclosure of Ten Largest Stock Holdings

Each of the Vanguard equity funds and Vanguard balanced funds generally will seek to disclose the fund’s ten largest stock portfolio holdings and the percentages that each of these ten largest stock portfolio holdings represents of the fund’s total assets as of the end of the most recent calendar quarter (quarter-end ten largest stock holdings) online at www.vanguard.com in the “Portfolio” section of the fund’s Portfolio & Management page, 15 calendar days after the end of the calendar quarter. In addition, those funds generally will seek to disclose the fund’s ten largest stock portfolio holdings as of the end of the most recent month (month-end ten largest stock holdings) online at www.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 of the Vanguard funds, 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 www.vanguard.com in the “Portfolio” section of the fund’s Portfolio & Management page, 30 calendar days after the end of the calendar quarter. 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 www.vanguard.com in the “Portfolio” section of the Fund’s Portfolio & Management page, 60 calendar days after the end of the calendar quarter. Each of the Vanguard money market funds generally will seek to disclose the fund’s complete portfolio holdings as of the end of the most recent month online at www.vanguard.com in the “Portfolio” section of the fund’s Portfolio & Management page, approximately 2 business days after the end of the month. Online disclosure of complete portfolio holdings is made to all

B-28

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 as previously described and, after consultation with a Vanguard fund’s investment advisor, may withhold any portion of the fund’s complete portfolio holdings from online disclosure as previously described when deemed to be in the best interests of the fund.

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 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.

Currently, Vanguard fund complete portfolio holdings are disclosed to the following Service Providers as part of ongoing arrangements that serve legitimate business purposes: Abel/Noser Corporation, Advisor Software, Inc., Alcom Printing Group Inc., Apple Press, L.C., Bloomberg L.P., Brilliant Graphics, Inc., Broadridge Financial Solutions, Inc., Brown Brothers Harriman & Co., FactSet Research Systems Inc., Innovation Printing & Communications, Intelligencer Printing Company, Investment Technology Group, Inc., Lipper, Inc., McMunn Associates Inc., Oce’ Business Services, Inc., Reuters America Inc., R.R. Donnelley, Inc., State Street Bank and Trust Company, Triune Color Corporation, and Tursack Printing Inc.

Disclosure of Complete Portfolio Holdings to Vanguard Affiliates and Certain Fiduciaries Subject to Confidentiality and Trading Restrictions

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

B-29

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.

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 determine whether to 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.

Currently, Vanguard nonmaterial portfolio holdings information is disclosed to KPMG, LLP, and R.V. Kuhns & Associates.

B-30

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 Fund Financial Services, 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.

Prohibitions on Disclosure of Portfolio Holdings

No person is authorized to disclose Vanguard fund portfolio holdings or other investment positions (whether online at www.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 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 Funds receive all investment advisory services from Vanguard, through its Quantitative Equity Group. These services on an at-cost basis from an experienced investment management staff employed directly by Vanguard.

Other Accounts Managed

(TBD)

B-31

Material Conflicts of Interest

At Vanguard, individual portfolio managers may manage multiple accounts for multiple clients. In addition to mutual funds, these other accounts may include separate accounts, collective trusts, or offshore funds. Managing multiple 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 with other types of accounts through allocation policies and procedures, internal review processes, and oversight by directors 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.

Description of Compensation

The named Vanguard portfolio managers are Vanguard employees. This section describes the compensation of the Vanguard employees who manage Vanguard mutual funds. As of August 31, 2009, 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 1980’s to restore dollar-for-dollar the benefits of management employees that had 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 the Vanguard 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 when a market adjustment of the position occurs.

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 its objectives, policies, strategies, and limitations, and the market environment during the measurement period. This performance factor is not based on the value of assets held in the fund’s portfolio. For each fund, the performance factor depends on how successfully the portfolio manager maintains the credit quality of the fund, and, consequently, how the fund performs relative to the expectations described above over a one-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 paid may be more or less than the target bonus, based on how well the manager satisfies the objectives stated above. 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.

Duration and Termination of Investment Advisory Agreement

Vanguard provides at-cost investment advisory services to the Funds 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 a 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

B-32

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 Funds. The advisor may cause a 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 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 a 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.

Some securities that are considered for investment by a Fund may also be appropriate for other Vanguard funds or for other clients served by the advisor. If such securities are compatible with the investment policies of a Fund and one or more of the advisor’s other clients, and are considered for purchase or sale at or about the same time, then transactions in such securities will be aggregated by the advisor and the purchased securities or sale proceeds will 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 Funds‘ board of trustees.

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 oversight of proxy voting to the Proxy Oversight Committee (the Committee), made up of senior officers of Vanguard, a majority of whom are also officers of each Vanguard fund, 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. While 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.

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 if that 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, or if exercising the vote would result in the imposition of trading or other restrictions.

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

B-33

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 Proxy Oversight 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 Nominated slate results in board made up of a majority of independent directors. All members of Audit, Nominating, and Compensation committees are independent of management.	Factors Against Approval Nominated slate results in board made up of a majority of non-independent directors. Audit, Nominating, and/or Compensation committees include 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 option 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 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

B-34

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

Company requires senior executives to hold a minimum amount
of company stock (frequently expressed as a multiple of salary).
Company requires stock acquired through option exercise to be
held for a certain period of time.
Compensation program includes performance-vesting awards,
indexed options, or other performance-linked grants.
Concentration of option grants to senior executives is limited
(indicating that the plan is very broad-based).
Stock-based compensation is clearly used as a substitute for
cash in delivering market-competitive total pay.

B. Bonus plans

Factors Against Approval

Total potential dilution (including all stock-based plans) exceeds 15% of
shares outstanding.
Annual option grants have exceeded 2% of shares outstanding.

Plan permits repricing or replacement of options without
shareholder approval.
Plan provides for the issuance of reload options.

Plan contains automatic share replenishment (evergreen) feature.

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. 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 triggered by a change in control that do not exceed three times an executive’s salary and bonus may generally be approved by the compensation committee of the board without submission to shareholders. Any such arrangement under which the beneficiary receives more than three times salary and bonus—or where severance is guaranteed absent a change in control—should be submitted for shareholder approval.

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

B-35

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

Plan is relatively short-term (3-5 years).
Plan requires shareholder approval for renewal.
Plan incorporates review by a committee of independent
directors at least every three years (so-called TIDE provisions).
Plan includes permitted-bid/qualified-offer feature (chewable
pill) that mandates a shareholder vote in certain situations.
Ownership trigger is reasonable (15-20%).
Highly independent, non-classified board.

B. Cumulative voting

Factors Against Approval

Plan is long term (>5 years).
Renewal of plan is automatic or does not require shareholder approval.
Ownership trigger is less than 15%.

Classified board.

Board with limited independence.

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.

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.

B-36

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 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.

VIII. 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.

IX. 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, a majority of whom are also officers of each Vanguard fund.

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 www.vanguard.com .

INFORMATION ABOUT THE ETF SHARE CLASS

Each Fund offers and issues an exchange-traded class of shares called ETF Shares. Each ETF Fund issues ETF Shares in large blocks, known as “Creation Units.” To purchase or redeem a Creation Unit, you must be an Authorized Participant or you must do so through a broker that is an Authorized Participant. An Authorized Participant is a participant in the Depository Trust Company (the DTC) that has executed a Participant Agreement with Vanguard Marketing Corporation, the Funds’ distributor (the Distributor).

Each ETF Fund issues Creation Units in kind, in exchange for a basket of stocks that are part of—or soon to be part of—its target index (Deposit Securities). Each ETF Fund also redeems Creation Units in kind; an investor who tenders a Creation Unit will receive, as redemption proceeds, a basket of stocks that are part of the Fund‘s portfolio holdings (Redemption Securities). The Deposit Securities and the Redemption Securities will usually, but may not necessarily always, be the same. As part of any creation or redemption transaction, the investor will either pay or receive some cash in addition to the securities, as described more fully below. Each ETF Fund reserves the right to issue Creation Units for cash, rather than in kind, although each has no current intention of doing so.

The ETF Shares have been approved for listing on a national securities exchange and will trade on the exchange at market prices that may differ from net asset value. There can be no assurance that, in the future, ETF Shares will continue to meet all of the exchange’s listing requirements. The exchange may, but is not required to, delist a Fund’s ETF Shares from listing if: (1) following the initial 12-month period beginning upon the commencement of trading, there are fewer than 50 beneficial owners of the ETF Shares for 30 or more consecutive trading days; (2) the value of the target index tracked by the Fund is no longer calculated or available; or (3) such other event shall occur or condition exist that, in the opinion of the exchange, makes further dealings on the exchange inadvisable. The exchange will also delist a Fund’s ETF Shares upon termination of the ETF Share class.

As with any stock traded on an exchange, purchases and sales of ETF Shares will be subject to usual and customary brokerage commissions.

CONVERSIONS AND EXCHANGES

Owners of conventional (i.e., not exchange-traded) shares issued by an ETF Fund may convert those shares into ETF Shares of equivalent value of the same Fund. Note: Investors who own conventional shares through a 401(k) plan or other employer-sponsored retirement or benefit plan may not convert those shares into ETF Shares. Vanguard will impose a charge on conversion transactions and reserves the right, in the future, to limit or terminate the conversion privilege. ETF Shares, whether acquired through a conversion or purchased on the open market, cannot be converted into conventional shares of the same fund. Similarly, ETF Shares of one fund cannot be exchanged for ETF Shares of another fund.

Investors that are not Authorized Participants must hold ETF Shares in a brokerage account. Thus, before converting conventional shares into ETF Shares, an investor must have an existing, or open a new, brokerage account. To initiate a conversion of conventional shares into ETF Shares, an investor must contact his or her broker. The broker may charge a fee, over and above Vanguard‘s fee, to process a conversion request.

Converting conventional shares into ETF Shares generally is accomplished as follows. First, after the broker notifies Vanguard of an investor‘s request to convert, Vanguard will transfer conventional shares from the investor‘s account with Vanguard to the broker‘s omnibus account with Vanguard (an account maintained by the broker on behalf of all its customers who hold conventional Vanguard fund shares through the broker). At this point, Vanguard will no longer have any record of the investor; his or her ownership of conventional shares and ETF Shares will be known only to his or her broker. Next, the broker will instruct Vanguard to convert the appropriate number or dollar amount of conventional shares in its omnibus account into ETF Shares of equivalent value, based on the respective net asset values of the two share classes. The Fund’s transfer agent will reflect ownership of all ETF Shares in the name of the DTC. The DTC will keep track of which ETF Shares belong to the broker and the broker, in turn, will keep track of which ETF Shares belong to its customers. Because the DTC is unable to handle fractional shares, only whole shares will be converted. For example, if

B-38

the investor owned 300.250 conventional shares, and this was equivalent in value to 90.750 ETF Shares, the DTC account would receive 90 ETF Shares. Conventional shares worth 0.750 ETF Shares (in this example, that would be 2.481 conventional shares) would remain in the broker‘s omnibus account with Vanguard. The broker then could either (1) take certain internal actions necessary to credit the investor‘s account with 0.750 ETF Shares rather than 2.481 conventional shares, or (2) redeem the 2.481 conventional shares at net asset value, in which case the investor would receive cash in lieu of those shares. If the broker chooses to redeem the conventional shares, the investor will realize a gain or loss on the redemption that must be reported on his or her tax return (unless he or she holds the shares in an IRA or other tax-deferred account). Investors should consult their brokers for information on how the brokers will handle the conversion process, including whether they will impose a fee to process a conversion.

The conversion process works differently if the investor opts to hold ETF Shares through an account at Vanguard Brokerage Services (Vanguard Brokerage). If the investor converts his or her conventional shares to ETF Shares through Vanguard Brokerage, all conventional shares for which he or she requests conversion will be converted into the equivalent amount of ETF Shares. Because no fractional shares will have to be sold, the transaction will be 100% tax-free.

Here are some important points to keep in mind when converting conventional shares of an ETF Fund into ETF Shares:

The conversion transaction is nontaxable except, as applicable, to the limited extent described above.
The conversion process can take anywhere from several days to several weeks, depending on the broker. Vanguard generally will process conversion requests either on the day they are received or on the next business day. Vanguard imposes conversion blackout windows around the dates when an ETF Fund declares dividends. This is necessary to prevent a shareholder from collecting a dividend from both the conventional share class currently held and also from the ETF share class into which the shares will be converted.
During the conversion process, the investor will remain fully invested in the Fund‘s conventional shares, and his or her investment will increase or decrease in value in tandem with the net asset value of those shares.
During the conversion process, the investor will be able to liquidate all or part of his or her investment by instructing Vanguard or his or her broker (depending on whether his or her shares are held in his or her own account or his or her broker‘s omnibus account) to redeem his or her conventional shares. After the conversion process is complete, the investor will be able to liquidate all or part of his or her investment by instructing his or her broker to sell his or her ETF Shares.

BOOK ENTRY ONLY SYSTEM

Each ETF Shares are registered in the name of the DTC or its nominee, Cede & Co., and deposited with, or on behalf of, the DTC. The DTC is a limited-purpose trust company that was created to hold securities of its participants (the DTC Participants) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. The DTC is a subsidiary of the Depository Trust and Clearing Corporation (the DTCC) which is owned by certain participants of DTCC’s subsidiaries, including the DTC. Access to the DTC system is also available to others such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (the Indirect Participants).

Beneficial ownership of ETF Shares is limited to DTC Participants, Indirect Participants, and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in ETF Shares (owners of such beneficial interests are referred to herein as Beneficial Owners) is shown on, and the transfer of ownership is effected only through, records maintained by the DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of ETF Shares.

Each ETF Fund recognizes the DTC or its nominee as the record owner of all ETF Shares for all purposes. Beneficial Owners of ETF Shares are not entitled to have ETF Shares registered in their names, and will not receive or be entitled to physical delivery of share certificates. Each Beneficial Owner must rely on the procedures of the DTC and any DTC Participant and/or Indirect Participant through which such Beneficial Owner holds its interests, to exercise any rights of a holder of ETF Shares.

B-39

Conveyance of all notices, statements, and other communications to Beneficial Owners is effected as follows. The DTC will make available to the Trust upon request and for a fee a listing of the ETF Shares of each Fund held by each DTC Participant. The Trust shall obtain from each such DTC Participant the number of Beneficial Owners holding ETF Shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement, or other communication, in such form, number, and at such place as such DTC Participant may reasonably request, in order that such notice, statement, or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to the DTC or its nominee as the registered holder of all ETF Shares. The DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in ETF Shares of the appropriate Fund as shown on the records of the DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of ETF Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners; or payments made on account of beneficial ownership interests in such ETF Shares; or for maintaining, supervising, or reviewing any records relating to such beneficial ownership interests; or for any other aspect of the relationship between the DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

The DTC may determine to discontinue providing its service with respect to ETF Shares at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action either to find a replacement for the DTC to perform its functions at a comparable cost or, if such replacement is unavailable, to issue and deliver printed certificates representing ownership of ETF Shares, unless the Trust makes other arrangements with respect thereto satisfactory to the exchange.

PURCHASE AND ISSUANCE OF ETF SHARES IN CREATION UNITS

Except for conversion into ETF Shares from other conventional shares, the ETF Funds issue and sell ETF Shares only in Creation Units on a continuous basis through the Distributor, without a sales load, at their net asset value next determined after receipt, on any Business Day, of an order in proper form. The ETF Funds will not issue fractional Creation Units.

A Business Day is any day on which the NYSE is open for business. As of the date of this Statement of Additional Information, the NYSE observes the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day (Washington’s Birthday), Good Friday, Memorial Day (observed), Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

Fund Deposit

The consideration for purchase of a Creation Unit from an ETF Fund generally consists of the in-kind deposit of a designated portfolio of equity securities (the Deposit Securities) and an amount of cash (the Cash Component) consisting of a Balancing Amount (described below) and a Transaction Fee (also described below). Together, the Deposit Securities and the Cash Component constitute the Fund Deposit.

The Balancing Amount is an amount equal to the difference between the net asset value (NAV) of a Creation Unit and the market value of the Deposit Securities (the Deposit Amount). It ensures that the NAV of a Fund Deposit (not including the Transaction Fee) is identical to the NAV of the Creation Unit it is used to purchase. If the Balancing Amount is a positive number ( i.e. , the NAV per Creation Unit exceeds the market value of the Deposit Securities), then that amount will be paid by the purchaser to the ETF Fund in cash. If the Balancing Amount is a negative number ( i.e. , the NAV per Creation Unit is less than the market value of the Deposit Securities), then that amount will be paid by the ETF Fund to the purchaser in cash (except as offset by the Transaction Fee, described below).

B-40

Vanguard, through the National Securities Clearing Corporation (the NSCC) (discussed below), makes available on each Business Day, a list of the names and the required number of shares of each Deposit Security to be included in the current Fund Deposit for each ETF Fund (based on information at the end of the previous Business Day). The Fund Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of an ETF Fund until such time as the next-announced Fund Deposit composition is made available. Each ETF Fund reserves the right to accept a nonconforming Fund Deposit.

The identity and number of shares of the Deposit Securities required for a Fund Deposit may change from one day to another to reflect rebalancing adjustments and corporate actions, or in response to adjustments to the weighting or composition of the component stocks of the relevant target index. In addition, the Trust reserves the right to permit or require the substitution of an amount of cash— i.e. , a “cash in lieu” amount—to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery, may not be eligible for transfer through the Clearing Process (discussed below), or may not be eligible for trading by an Authorized Participant (as defined below) or the investor for which an Authorized Participant is acting. Brokerage commissions incurred in connection with acquisition of Deposit Securities not eligible for transfer through the systems of the DTC and hence not eligible for transfer through the Clearing Process will be an expense of the Fund. However, Vanguard may adjust the Transaction Fee (described below) to protect existing shareholders from this expense.

All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility, and acceptance for deposit of any securities to be delivered shall be determined by the appropriate ETF Fund, and the Fund’s determination shall be final and binding.

Procedures For Purchasing Creation Units

To be eligible to place orders with the Distributor and to purchase Creation Units from an ETF Fund, you must be an Authorized Participant, i.e., a DTC Participant that has executed a Participant Agreement with the Distributor governing the purchase and redemption of Creation Units. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant in order to purchase or redeem a Creation Unit. If your broker is not a DTC Participant or has not executed a Participant Agreement, it will have to place your order through an Authorized Participant, which may result in additional charges to you. For a current list of Authorized Participants, contact the Distributor.

An Authorized Participant may place an order to purchase (or redeem) Creation Units of an ETF Fund either (1) through the Continuous Net Settlement (the CNS) clearing processes of the NSCC as such processes have been enhanced to effect purchases (and redemptions) of Creation Units, such processes being referred to herein as the Clearing Process, or (2) outside the Clearing Process. To purchase or redeem through the Clearing Process, an Authorized Participant must be a member of NSCC that is eligible to use the CNS system. Purchases (and redemptions) of Creation Units cleared through the Clearing Process will be subject to a lower Transaction Fee than those cleared outside the Clearing Process.

To initiate a purchase order for a Creation Unit, whether through the Clearing Process or outside the Clearing Process, an Authorized Participant must give notice to the Distributor. The order must be in proper form and must be received by the Distributor prior to the closing time of the regular trading session on the NYSE (Closing Time) (ordinarily 4 p.m., Eastern time) to receive that day‘s NAV. The date on which an order to purchase (or redeem) Creation Units is placed is referred to as the Transmittal Date. Orders must be transmitted by an Authorized Participant by a transmission method acceptable to the Distributor pursuant to procedures set forth in the Participation Agreement.

Purchase orders effected outside the Clearing Process are likely to require transmittal by the Authorized Participant earlier on the Transmittal Date than orders effected using the Clearing Process. Those persons placing orders outside the Clearing Process should ascertain the deadlines applicable to the DTC and the Federal Reserve Bank wire system by contacting the operations department of the broker or depository institution effectuating such transfer of Deposit Securities and Cash Component.

Neither the Trust, the ETF Fund, the Distributor, nor any affiliated party will be liable to an investor who is unable to submit a purchase order by Closing Time, even if the problem is the responsibility of one of those parties ( e.g. , the Distributor‘s phone systems or fax machines were not operating properly).

If you are not an Authorized Participant, you must place your purchase order with an Authorized Participant in a form acceptable to such Authorized Participant. In addition, the Authorized Participant may request that you make certain representations or enter into agreements with respect to the order, e.g. , to provide for payments of cash when required.

B-41

You should afford sufficient time to permit proper submission of the order by the Authorized Participant to the Distributor prior to Closing Time on the Transmittal Date.

Placement of Purchase Orders Using Clearing Process

For purchase orders placed through the Clearing Process, the Authorized Participant Agreement authorizes the Distributor to transmit through the Transfer Agent or Index Receipt Agent to the NSCC, on behalf of an Authorized Participant, such trade instructions as are necessary to effect the Authorized Participant‘s purchase order. Pursuant to such trade instructions to the NSCC, the Authorized Participant agrees to deliver the requisite Deposit Securities and the Cash Component to the appropriate ETF Fund, together with such additional information as may be required by the Distributor.

An order to purchase Creation Units through the Clearing Process is deemed received on the Transmittal Date if (1) such order is received by the Distributor not later than the Closing Time on such Transmittal Date, and (2) all other procedures set forth in the Participant Agreement are properly followed. Such order will be effected based on the NAV of the Fund next determined on that day. An order to purchase Creation Units through the Clearing Process made in proper form but received after Closing Time on the Transmittal Date will be deemed received on the next Business Day immediately following the Transmittal Date and will be effected at the NAV next determined on that day. The Deposit Securities and the Cash Component will be transferred by the third NSCC Business Day following the date on which the purchase request is deemed received.

Placement of Purchase Orders Outside Clearing Process

An Authorized Participant that wishes to place an order to purchase Creation Units outside the Clearing Process must state that it is not using the Clearing Process and that the purchase instead will be effected through a transfer of securities and cash directly through the DTC. An order to purchase Creation Units outside the Clearing Process is deemed received by the Distributor on the Transmittal Date if (1) such order is received by the Distributor not later than the Closing Time on such Transmittal Date; and (2) all other procedures set forth in the Participant Agreement are properly followed. If a Fund‘s custodian does not receive the Deposit Securities and Cash Component by the settlement date (T+3 unless otherwise agreed), the Fund shall be entitled to cancel the purchase order and/or charge the purchaser for any costs (including investment losses, attorney‘s fees, and interest) sustained by the Fund as a result of the late delivery or failure to deliver.

An ETF Fund may issue Creation Units to a purchaser before receiving some or all of the Deposit Securities if the purchaser deposits, in addition to the available Deposit Securities and the Cash Component, an additional cash deposit in an amount determined by the Fund.

Rejection of Purchase Orders

Each of the ETF Funds reserves the absolute right to reject a purchase order transmitted to it by the Distributor. By way of example, and not limitation, an ETF Fund will reject a purchase order if:

the order is not in proper form;
the investor(s), upon obtaining the ETF Shares ordered, would own 80% or more of the total combined voting power of all classes of stock issued by the ETF Fund;
the Deposit Securities delivered are not as disseminated through the facilities of the NSCC for that date;
acceptance of the Deposit Securities would have certain adverse tax consequences to the ETF Fund;
acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful;
acceptance of the Fund Deposit would otherwise, in the discretion of the ETF Fund or Vanguard, have an adverse effect on the Fund or any of its shareholders; or
circumstances outside the control of the ETF Fund, the Transfer Agent, the custodian, the Distributor, and Vanguard make it for all practical purposes impossible to process the order. Examples of such circumstances include natural disasters; public service disruptions, or utility problems such as fires, floods, extreme weather conditions, and power outages resulting in telephone, telecopy, and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the Trust, Vanguard, the Distributor, the DTC, the NSCC, or any other participant in the purchase process; and similar extraordinary events.

B-42

The Distributor shall notify the prospective purchaser of a Creation Unit, and/or the Authorized Participant acting on the purchaser‘s behalf, of its rejection of the purchaser‘s order. The ETF Funds, the Transfer Agent, the custodian, and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of a Fund Deposit, nor shall any of them incur any liability for the failure to give any such notification.

Transaction Fee on Purchases of Creation Units

Each of the ETF Funds imposes a transaction fee (payable to the Fund) to compensate the Fund for the transfer and other transaction costs associated with the issuance of Creation Units. For purchases effected through the Clearing Process, the transaction fee for • ETF Shares is • regardless of how many Creation Units are purchased. An additional charge may be imposed for purchases effected outside the Clearing Process. The maximum transaction fees for purchases and redemptions of the ETF Shares are as follows:


Vanguard S&P 500 Growth ETF Vanguard S&P 500 Value ETF Vanguard S&P Mid-Cap 400 ETF Vanguard S&P Mid-Cap 400 Growth ETF Vanguard S&P Mid-Cap 400 Value ETF Vanguard S&P Small-Cap 600 ETF Vanguard S&P Small-Cap 600 Growth ETF Vanguard S&P Small-Cap 600 Value ETF	$• • • • • • • •

When an ETF Fund permits (or requires) a purchaser to substitute cash in lieu of depositing one or more Deposit Securities, the purchaser will be assessed an additional variable charge on the “cash in lieu” portion of its investment. The amount of this variable charge shall be determined by the ETF Fund in its sole discretion, but shall not be more than is reasonably needed to compensate the Fund for the brokerage costs associated with purchasing the relevant Deposit Securities and, if applicable, the estimated market impact costs of purchasing such securities.

REDEMPTION OF ETF SHARES IN CREATION UNITS

ETF Shares may be redeemed only in Creation Units; an ETF Fund will not redeem ETF Shares tendered in less than Creation Unit-size aggregations. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of ETF Shares to constitute a redeemable Creation Unit. There can be no assurance, however, that there will be sufficient liquidity in the public trading market at any time to permit assembly of a Creation Unit. Redemption requests in good order will receive the NAV next determined after the request is made.

An investor tendering a Creation Unit generally will receive redemption proceeds consisting of (1) a basket of Redemption Securities, plus (2) a Cash Redemption Amount equal to the difference between (x) the NAV of the Creation Unit being redeemed, as next determined after receipt of a request in proper form, and (y) the value of the Redemption Securities, less (3) a Redemption Transaction Fee (described below). If the Redemption Securities have a value greater then the NAV of a Creation Unit, the redeeming investor would pay the Cash Redemption Amount to the ETF Fund, rather than receiving such amount from the Fund.

Vanguard, through the NSCC, makes available after the close of each Business Day a list of the names and the number of shares of each Redemption Security to be included in the next Business Day’s redemption basket (subject to possible amendment or correction). The basket of Redemption Securities provided to an investor redeeming a Creation Unit may not be identical to the basket of Deposit Securities required of a investor purchasing a Creation Unit. If an ETF Fund and a redeeming investor mutually agree, the Fund may provide the investor with a basket of Redemption Securities that differs from the composition of the redemption basket published through the NSCC.

Each ETF Fund reserves the right to deliver cash in lieu of any Redemption Security for the same reason it might accept cash in lieu of a Deposit Security, as discussed above, or if the Fund could not lawfully deliver the security or could not do so without first registering such security under federal or state law.

Neither the Trust, the ETF Fund, the Distributor, nor any affiliated party will be liable to an investor who is unable to submit a redemption order by Closing Time, even if the problem is the responsibility of one of those parties ( e.g. , the Distributor‘s phone systems or fax machines were not operating properly).

B-43

Transaction Fees on Redemptions of Creation Units

Each of the ETF Funds imposes a transaction fee (payable to the Fund) to compensate the Fund for the transfer and other transaction costs associated with the redemption of Creation Units. For redemptions effected through the Clearing Process, the transaction fee is $500 for all U.S. Stock Index ETF Shares regardless of how many Creation Units are redeemed. An additional charge may be imposed for redemptions effected outside the Clearing Process. The maximum transaction fee for redemptions is shown in the previous table.

When an ETF Fund permits (or requires) a redeeming investor to receive cash in lieu of one or more Redemption Securities, the investor will be assessed an additional variable charge on the “cash in lieu” portion of its redemption. The amount of this variable charge shall be determined by the Fund in its sole discretion, but shall not be more than is reasonably needed to compensate the Fund for the brokerage costs associated with selling portfolio securities to raise the necessary cash and, if applicable, the estimated market impact costs of selling such securities.

Placement of Redemption Orders Using Clearing Process

An order to redeem Creation Units through the Clearing Process is deemed received on the Transmittal Date if (1) such order is received by the Distributor not later than the Closing Time on such Transmittal Date, and (2) all other procedures set forth in the Participant Agreement are properly followed. Such order will be effected based on the NAV of the ETF Fund next determined on that day. An order to redeem Creation Units through the Clearing Process made in proper form but received by a Fund after Closing Time on the Transmittal Date will be deemed received on the next Business Day immediately following the Transmittal Date and will be effected at the NAV next determined on that day. The Redemption Securities and the Cash Redemption Amount will be transferred by the third NSCC Business Day following the date on which the redemption request is deemed received.

Placement of Redemption Orders Outside Clearing Process

An Authorized Participant that wishes to place an order to redeem a Creation Unit outside the Clearing Process must state that it is not using the Clearing Process and that redemption instead will be effected through a transfer of ETF Shares directly through DTC. An order to redeem a Creation Unit of an ETF Fund outside the Clearing Process is deemed received on the Transmittal Date if (1) such order is received by the Fund‘s Transfer Agent prior to the Closing Time on such Transmittal Date; and (2) all other procedures set forth in the Participant Agreement are properly followed. If the ETF Fund‘s custodian does not receive the required number of ETF Shares from the redeeming investor by the settlement date (T+3 unless otherwise agreed), the Fund shall be entitled to charge the redeeming investor for any costs (including investment losses, attorney‘s fees, and interest) sustained by the Fund as a result of the late delivery or failure to deliver.

After the Transfer Agent has deemed an order for redemption outside the Clearing Process received, the Transfer Agent will initiate procedures to transfer the Redemption Securities and the Cash Redemption Amount to the Authorized Participant on behalf of the redeeming Beneficial Owner by the third Business Day following the Transmittal Date on which such redemption order is deemed received by the Transfer Agent.

The calculation of the value of the Redemption Securities and the Cash Redemption Amount to be delivered upon redemption will be made by the custodian on the Business Day on which a redemption order is deemed received by the Transfer Agent. Therefore, if a redemption order in proper form is submitted to the Transfer Agent by an Authorized Participant prior to the Closing Time on the Transmittal Date, then the value of the Redemption Securities and the Cash Redemption Amount will be determined by the Custodian on such Transmittal Date.

Each of the ETF Funds reserves the right, in its sole discretion, to require or permit a redeeming investor to receive its redemption proceeds in cash. In such cases, the investor would receive a cash payment equal to the NAV of its ETF Shares based on the NAV of those shares next determined after the redemption request is received in proper form (minus a transaction fee, including a charge for cash redemptions, described above).

If a redeeming investor (or an Authorized Participant through which it is acting) is subject to a legal restriction with respect to a particular stock included in the basket of Redemption Securities, such investor may be paid an equivalent amount of cash in lieu of the stock. In addition, each ETF Fund reserves the right to redeem Creation Units partially for cash to the extent that the Fund could not lawfully deliver one or more Redemption Securities or could not do so without first registering such securities under federal or state law.
