Fund Summary

Investment Objective

Vanguard Developed Markets ex-US Growth Index ETF (the “Fund”) seeks to track the performance of a benchmark index that measures the investment return of large- and mid-cap growth stocks issued by companies located in developed market countries, excluding the United States.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy, hold, and sell ETF shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below.

Shareholder Fees

(Fees paid directly from your investment)

*None through Vanguard (Broker fees vary)

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

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 pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund has no operating history and therefore has no portfolio turnover information.

Principal Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the S&P Developed Ex-U.S. LargeMidCap Growth Index, (the “Target Index”), a float-adjusted market capitalization-weighted index that is made up of common stocks of large- and mid-cap growth companies located in developed markets countries, excluding the United States. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in stocks that make up the Target Index. The Fund attempts to replicate the Target Index by seeking to invest all, or substantially all, of its assets in the stocks that make up the Target Index, in order to hold each stock in approximately the same proportion as its weighting in the Target Index.

Principal Risks

As with any investment, an investment in the Fund could lose money over any time period. The Fund’s share price and total return may fluctuate, potentially within a wide range. The principal risks of investing in the Fund are summarized below. Each of the following risks could affect the Fund’s performance:

•General Market Risk. The markets in which the Fund invests can be affected by a variety of factors. These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and

developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund’s investments, thereby resulting in potential losses to the Fund over short or long periods.

•Investing in Foreign Markets. Foreign markets can perform differently than U.S. markets. World events could adversely affect the value and/or liquidity of securities of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in such country or region.

•Currency Risk. The Fund is subject to the risk that foreign currency will perform differently than U.S. dollars and increase the potential loss to the Fund. Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund. Changes in currency exchange rates can affect the value of the Fund’s holdings.

•Investing in Equity Markets. The Fund invests in the equity markets. Equity markets have historically been cyclical, having periods of time when stock values rise and fall. Market volatility can lead to significant fluctuations in stock values, resulting in potential losses to the Fund.

•Market Capitalization (Market Cap). Companies are generally classified into three types of market cap depending on their size: small-, mid-, and large-cap. Companies can be further classified into micro- or mega-cap.

Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.

•Growth Investing. The Fund’s approach to growth investing could cause it to underperform other stock funds that use a different investment style. Growth stocks typically produce lower yields because growth companies prefer to reinvest earnings into research and development to promote growth and increase profitability. Research and development can be expensive and may not always produce favorable results, which could harm a company’s performance relative to the broader market.

•Index Investing. The Fund is subject to risks associated with index investing. Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund’s performance may be lower than it would be if it were actively managed. Although the Fund seeks to hold substantially all of the securities included in the Target Index, it may be unable to do so. In addition, the Fund could be prevented from holding one or more securities in the same proportion as in the Target Index. The performance of the Fund’s investments, in the aggregate, may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the Index Provider or by errors made by the Index Provider. Any gains, losses, or costs associated with or resulting from an error made by the Index Provider will generally be borne by the Fund and, as a result, the Fund’s shareholders.

•Concentration Risk. Except as may be necessary to approximate the composition of its Target Index, the Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry or group of industries. If the Target Index becomes concentrated and the Fund needs to concentrate in the same industry or group of industries, its performance could be negatively impacted by the industry or industries in which it is concentrated.

•ETF Share Trading. The Fund’s ETF shares are listed for trading on XX and individual investors may only buy and sell them on the secondary market at market prices. Although it is expected that the market price of an ETF share typically will approximate its net asset value (NAV), there may be times when the market price of an ETF share and its NAV differ significantly. Disruptions to creation and redemption transactions, the existence of significant market volatility or potential lack of an active trading market for ETF shares (including through a trading halt), as well as other factors, may result in ETF shares trading significantly above (at a premium) or below (at a discount) the Fund’s NAV or the intraday value of the Fund’s holdings. Thus, you may pay more or less than NAV when you buy ETF shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

•Authorized Participants. Only Authorized Participants may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that may act as Authorized

Participants. The Fund’s Authorized Participants are not obligated to engage in creation or redemption transactions. To the extent that the Fund’s Authorized Participants are unable to or choose not to proceed with creation and/or redemption transactions with respect to the Fund and no other Authorized Participants step forward to engage in creation or redemption transactions with the Fund, the Fund’s ETF shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

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.

Purchase and Sale of Fund Shares

ETF shares may only be bought and sold in the secondary market through a brokerage firm. The price you pay or receive for ETF shares will be the prevailing market price, which may be more (premium) or less (discount) than the NAV of the shares. The brokerage firm may charge you a commission to execute the transaction. Unless imposed by your brokerage firm, there is no minimum dollar amount you must invest and no minimum number of shares you must buy. ETF shares of the Fund cannot be directly purchased from or redeemed with the Fund, except by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF shares only in large blocks known as creation units, typically in exchange for baskets of securities.

An investor in ETF shares may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF shares (bid) and the lowest price a seller is willing to accept for ETF shares (ask) when buying or selling shares in the secondary market (bid-ask spread). Recent information about the Fund and its ETF shares, including information on the Fund’s NAV,

market price, premiums and discounts, and bid-ask spreads, is available online at vanguard.com.

Tax Information

The Fund’s distributions may be taxable as ordinary income or capital gains. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. You should consult your own tax advisor with respect to any particular U.S. or non- U.S. tax consequences of your investment in the Fund.

Payments to Financial Intermediaries

The Fund and its advisor do not pay financial intermediaries for sales of Fund shares.

More on the Fund

This prospectus provides information about Vanguard Developed Markets ex-US Growth Index ETF, an exchange-traded fund (the “Fund”). The Fund is a series of Vanguard World Fund (the “Trust”). Unlike conventional mutual fund shares, ETF shares cannot be purchased directly from or redeemed directly with the issuing fund by an individual investor. Instead, only certain authorized broker- dealers (“Authorized Participants”) can purchase and redeem ETF shares directly from the issuing fund at net asset value. Authorized Participants may purchase and redeem ETF shares from the issuing fund only in large blocks (creation units), usually in exchange for baskets of securities. Funds may also issue and redeem creation units in exchange for solely cash or a combination of cash and securities. These trades may occur in-kind between Vanguard and the Authorized Participant. Individual investors can purchase ETF shares on the secondary market through a broker. Reading this prospectus will help you decide whether the Fund is the right investment for you.

As you consider an investment in the Fund’s ETF shares, you should take into account your tolerance for fluctuations in the securities markets. The costs of investing are another important consideration. As a Fund shareholder, you will pay a proportionate share of the costs of operating the Fund and any transaction costs incurred when the Fund buys or sells securities, including costs generated by shareholders of other share classes to the extent the Fund offers more than one share class. These costs can erode a substantial portion of the gross income or the capital appreciation the Fund achieves. Even seemingly small differences can, over time, have a dramatic effect on the Fund’s performance.

Investment Objective and More on Principal Investment Strategies

In this section, you will find more information about the Fund’s investment objective and the principal investment strategies and policies that the Fund uses in pursuit of its investment objective. The Trust’s board of trustees (the “Board”) oversees the Fund’s management. The Board may approve changes to the Fund’s strategies or policies in the interest of shareholders without shareholder approval unless the strategy or policy is designated as fundamental.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of large- and mid-cap growth stocks issued by companies located in developed market countries, excluding the United States.

The Fund’s investment objective is not fundamental and may be changed without shareholder approval.

Implementation of Investment Objective

To achieve its investment objective, the Fund employs an indexing, or passive, investment approach designed to track the performance of its Target Index, the S&P Developed Ex-U.S. LargeMidCap Growth Index.

What are Index Funds?

Index funds attempt to track—not outperform—the performance of a specified market index. An index is a group of securities whose overall performance is used as a standard to measure the investment performance of a particular market. Some indexes represent entire markets, such as the U.S. stock market, while others cover a segment of a market, such as short- term bonds.

One cannot invest directly in an index. Instead, an index fund’s advisor will typically seek to hold all, or substantially all, of the securities that make up the fund’s target index (often referred to as “replicating” an index or a “full replication” approach) or a representative sample of the securities that make up a fund’s target index (“sampling” an index).

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index. Investments in derivatives may be counted toward the Fund’s 80% policy to the extent that they provide investment exposure to the securities included within the policy or to one or more market risk factors associated with such securities. The Fund may change its 80% policy only upon 60 days’ notice to shareholders.

Security Selection

The Fund uses the replication method of indexing, meaning that the Fund generally holds the same stocks as those in its Target Index and in approximately the same proportions. The advisor buys and sells securities for the Fund for the purpose of tracking the Target Index.

The Fund’s Target Index is a float-adjusted market capitalization-weighted index designed to measure the top 85% of float-adjusted market capitalization in each developed country, excluding the United States. The Target Index is a subset of the S&P Global BMI, a comprehensive rules-based index measuring global stock market performance. The Fund’s Target Index is made up of common stocks of large- and mid-cap growth companies from developed markets excluding the United States.

As of XX XX, 20XX, the number of stocks (constituents) in the Target Index was approximately XX. The constituents of the Target Index are reviewed and rebalanced by the Index Provider on an annual basis in September each year and in connection with share changes and IPO updates in March, June and December each year.

The Target Index is owned, calculated, and controlled by the Index Provider in its sole discretion. Neither the advisor nor any of its affiliates has discretion to select Target Index components or change the Target Index’s methodology.

Stocks of publicly traded companies are often classified according to market capitalization, which is the market value of a company’s outstanding shares. These classifications typically include small-cap, mid-cap, and large-cap. It is important to understand that there is no “official” definition of each type of small- cap, mid-cap, or large-cap and that market capitalization ranges can change over time.

The Fund’s median market capitalization, which is the midpoint of the market capitalization of the fund’s stocks weighted by the proportion of the fund’s assets invested in each stock, can be used as an indicator of the size of the companies in which it invests. Stocks representing half of a fund’s assets will have market capitalizations above the median, and the rest will fall below it.

Additional Information Regarding the Fund’s Investments

The Fund’s investments are described in more detail below.

•Large-Cap Stocks represent the largest publicly traded companies, which are often well-established and widely recognized. These companies typically have significant market share, global reach, and a history of financial stability. While they may not offer as much growth potential as smaller companies, they are generally considered more resilient during economic downturns but still not immune from a decrease in price.

•Mid-Cap Stocks represent medium-sized companies, which can be companies that are more established than small-cap companies but do not have the market share of large-cap companies. These companies may be more agile than large-cap companies in responding to market changes, while also benefiting from more resources and operational maturity than small-cap companies. However, they can still face challenges during economic downturns.

•Growth Stocks typically represent companies that are expected to deliver above-average increases in revenue, earnings, cash flow, or other similar criteria. These stocks typically reinvest profits into the business rather than paying dividends, which results in low or no dividend yields. Growth stocks often trade at higher valuations relative to financial metrics like price-to- earnings or book value, as their prices are largely based on projections of future performance.

More on Fund Risks

Investing in the securities markets can result in a loss of principal. The Fund is subject to a variety of risks, including the principal risks listed below, that can impact its net asset value (NAV), performance, and ability to achieve its investment objective.

More on Principal Risks

General Market Risk. The markets in which the Fund invests can be affected by a variety of factors. These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund’s investments, thereby resulting in potential losses to the Fund over short or long periods.

Investing in Foreign Markets. Foreign markets can perform differently than U.S. markets. World events could adversely affect the value and/or liquidity of securities (including depositary receipts) of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. The performance of a fund that invests significantly in one or more countries or regions will be closely tied to factors within that country or region. These factors may include currency, economic, political, and/or regulatory conditions and developments. Therefore, the Fund’s performance may be affected disproportionately compared to a fund that does not invest significantly in such countries or regions.

Currency Risk. The Fund is subject to the risk that foreign currency will perform differently than U.S. dollars and increase the potential loss to the Fund. Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund. Changes in currency exchange rates can affect the value of the Fund’s holdings.

Investing in Equity Markets. The Fund invests in the equity markets. Equity markets have historically been cyclical, having periods of time when stock values rise and fall. These periods of rising and falling values can occur for unpredictable timeframes over the short- and long-term. Market volatility also is unpredictable and can lead to significant fluctuations in stock values, resulting in potential losses to the Fund.

Market Capitalization (Market Cap) – Large-Cap Companies. Large-cap companies are typically more well-established, well-known, and mature companies from an operational perspective than smaller cap companies.

Because of this, they may not reach the same levels of growth or performance as smaller cap companies, and they may be slower to react to competitive challenges. The Fund’s focus on large-cap companies could affect its performance relative to a fund that is focused on a broader representation of the stock market.

Market Capitalization (Market Cap) – Mid-Cap Companies. Mid-cap companies fall between large- and small-cap companies in size. Due to being smaller, they may be more affected by adverse business or economic events than larger companies. The Fund’s focus on mid-cap companies could affect its performance relative to a fund that is focused on a broader representation of the stock market.

Growth Investing. Companies and their stock are often classified as growth or value. Growth investing and value investing are two investment styles used by advisors. Under certain market conditions these investment styles may perform differently, generating varying returns. The Fund's approach to growth investing could cause it to underperform other stock funds that use a different investment style. Growth stocks typically produce lower yields because growth companies prefer to reinvest earnings into research and development to promote growth and increase profitability. Research and development can be expensive and may not always produce favorable results, which could harm a company’s performance relative to the broader market.

Index Investing. The Fund is subject to the following risks associated with index investing:

Passive Management. The Fund seeks to track the performance of its Target Index regardless of how the Target Index is performing. The advisor’s use of an indexing, or passive, approach to select and maintain investments for the Fund means that the advisor will select investments for the purpose of tracking the Target Index and generally will not use strategies to reduce negative impacts to the Fund during periods of market volatility. As a result, the Fund’s performance may be lower than it would be if it were actively managed.

Index Replication Strategy. Although the Fund seeks to hold substantially all of the securities included in its Target Index, it may be unable to do so. In addition, the Fund could be prevented from holding one or more of the securities in the same proportion as in the Target Index.

Tracking Error. The performance of the Fund’s investments, in the aggregate, may not match the investment performance of its Target Index. It is important to understand that an index fund will never perform exactly the same as its target index because, among other things, an index fund has operating expenses and transaction costs and its target index does not. Beyond these inherent differences in the operation of an index fund versus the operation of its target index, there are a variety of other factors that can cause or result in tracking error. These may include, but are not limited to:

oPrice differences between the securities held by the Fund and those included in its Target Index

oCash flows into or out of the Fund o The size of the Fund

o Compliance with new or existing regulatory requirements

o Portfolio transactions carried out by the advisor to minimize the distribution of capital gains

o Changes to the underlying securities that make up the Fund’s Target Index

o Errors made by the Index Provider

Tracking error risk may be heightened during times of increased market volatility or under other unusual market conditions. An index fund using a sampling strategy may be more likely to experience tracking error than an index fund using a replicating strategy.

Index Provider. The Fund is subject to risks associated with its Index Provider. The securities that make up the Target Index and their weighting in the Target Index are determined by the Index Provider. The Index Provider does not provide any warranty or accept any liability with respect to the quality, accuracy, or completeness of the Target Index or any data used to compile the Target Index. Under normal circumstances, the Index Provider rebalances (updates) the Target Index on a regular schedule. However, the Index Provider may also rebalance the Target Index outside of the regular schedule or delay or cancel a scheduled rebalance, which could result in added costs for the Fund or cause the Fund to experience tracking error. The Index Provider may make errors, and it is possible that such errors may not be identified by the Index Provider for a period of time or at all. Any gains, losses, or costs associated with or resulting from an error made by the Index Provider will generally be borne by the Fund and, as a result, the Fund’s shareholders. The Fund’s advisor does not provide any warranty or guarantee against any errors made by the Index Provider.

Concentration Risk. Except as may be necessary to approximate the composition of its Target Index, the Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry or group of industries. However, it is possible that the Target Index could become concentrated due to market conditions or the performance of a single or related group of issuers. If the Target Index becomes concentrated and the Fund needs to concentrate in the same industry or group of industries, its performance could be negatively impacted by the industry or industries in which it is concentrated.

ETF Share Trading. Because ETF shares trade on the secondary markets, they are subject to the following risks:

ETF Shares Trading at Prices Other Than NAV. ETF shares may trade on a national securities exchange at prices above, below or at their most recent NAV. The NAV of a Fund’s ETF shares, which typically is calculated at the end of each business day, will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of ETF shares will also fluctuate, in some cases materially, in accordance with changes in NAV and the intraday value of a Fund’s holdings, as well as the relative supply of and demand for the

ETF shares on an exchange. Differences between secondary market prices of ETF shares and the intraday value of a Fund’s holdings may be due largely to supply and demand forces in the secondary market, which may not be the same forces as those influencing prices for securities held by the Fund at a particular time.

Although it is expected that the market price of an ETF share typically will trade close to the value of a Fund’s holdings, market prices are not expected to correlate exactly to a Fund’s NAV due to timing reasons, supply and demand imbalances, and other factors. In addition, disruptions to creations and redemptions, adverse developments impacting market makers, authorized participants or other market participants, or high market volatility may result in the market price of ETF shares differing significantly from the Fund’s NAV or the intraday value of a Fund’s holdings. As a result of these factors, among others, you may pay more (premium) or less (discount) than NAV when you buy ETF shares on the secondary market, and you may receive more or less than NAV when you sell those shares. These discounts and premiums are likely to be greatest during times of market disruption or extreme market volatility.

Cost of Buying or Selling Shares. Individual investors who buy or sell ETF shares through a broker may incur a brokerage commission or other charges imposed by brokers. In addition, the market price of ETF shares, like the price of any security on an exchange, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The bid- ask spread is the difference between the highest price a buyer is willing to pay to purchase ETF shares (bid) and the lowest price a seller is willing to accept for ETF shares (ask) when buying or selling shares in the secondary market. The bid-ask spread of a Fund’s ETF shares can vary over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the bid-ask spread of the Fund’s underlying securities, or market liquidity decrease. In times of severe market disruption, including when trading of a Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that ETF shares may trade at a discount to a Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

Short Selling. ETF shares, similar to shares of other issuers listed on an exchange, may be sold short. In a short sale, an investor “borrows” securities from a lender for a fee and then sells the borrowed securities on the open market with the hope that the borrowed securities decline in price before the investor has to repurchase the securities to return them to the lender. Short sales of ETF shares can increase their volatility and lead to price decreases.

Lack of Active Trading Market. Although ETF shares are listed on a national securities exchange, it is possible that an active trading market may not be maintained. Although this could happen at any time, it is more likely to occur during times of severe market disruption. If you attempt to sell your ETF shares when an active trading market is not functioning, you may have to sell at a significant discount to NAV. In extreme cases, you may not be able to sell your shares at all.

Trading Halt. Trading of ETF shares on an exchange may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of ETF shares may also be halted if (1) the shares are delisted from the listing exchange without first being listed on another exchange or (2) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors. If a trading halt or unanticipated early closing of an exchange occurs, a shareholder may be unable to purchase or sell ETF shares.

Authorized Participants. Only Authorized Participants may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that may act as Authorized Participants. The Fund’s Authorized Participants are not obligated to engage in creation or redemption transactions. To the extent that the Fund’s Authorized Participants are unable to or choose not to proceed with creation and/or redemption transactions with respect to the Fund and no other Authorized Participants step forward to engage in creation or redemption transactions with the Fund, the Fund’s ETF shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

Additional Risks

Geopolitical and Sanctions Risk. Due to growing dependencies between global economies, geopolitical events can negatively affect all securities, markets, and economies. It is possible that events which only impact one geographic area could have negative short- or long-term effects on markets, issuers, and/or exchanges in the United States and other countries.

At times, the United States, other governments, or other supranational bodies (e.g., the United Nations) may impose sanctions on countries and/or entities in response to geopolitical events or other priorities. Compliance with sanctions could impact the Fund, including the Fund’s ability to transact in or obtain exposure to certain foreign securities and assets. Sanctions also could cause significant losses to the Fund’s investments and its performance could be negatively impacted. In lieu of sanctions, companies or specific goods that the company produces could be subjected to trade embargoes or tariffs, which can also affect securities markets and create volatility. So long as sanctions do not prohibit investment in the company or issuer, the Fund typically also would not be prohibited from investing in the affected company or issuer.

Potential Redemption Activity Impacts. The Vanguard funds can be negatively impacted by certain large redemptions. These redemptions could occur due to a single shareholder or multiple shareholders deciding to sell a large quantity of shares of a fund or a share class of the fund. Large redemptions can occur for many reasons, either as a result of actions taken by the Vanguard funds or their advisors, or as a result of events unrelated to actions taken by the Vanguard funds or their advisors. Actions taken by the

Vanguard funds or their advisors could include, but are not limited to, changes to a fund’s advisor(s), changes to a fund’s portfolio manager(s), changes to the composition of a fund’s portfolio, and/or other product changes or launches that, for example, result in shareholders redeeming shares of one fund to purchase shares of another fund or investment vehicle. For a fund of funds, actions taken by the Vanguard funds or their advisors could include a withdrawal from an underlying fund or a change in the allocation to underlying funds. Events unrelated to actions taken by the Vanguard funds or their advisors could include shareholders selling out of a fund in response to market movements or regulatory changes.

A large redemption could adversely affect a fund’s liquidity and NAV. For example, a large redemption could require a fund’s manager to sell portfolio holdings at unplanned or inopportune times. The manager’s sale of these holdings, which is a taxable event, could require the fund to distribute any corresponding capital gains or other taxable income to the fund’s remaining shareholders; see Dividends, Capital Gains, and Taxes for additional information. The increased trading activity could also increase underlying costs for the fund due to commissions paid by the fund.

Investing in Derivatives. Investing in derivatives may present risks different from, and/or greater than, those associated with investing directly in stocks, bonds, or other types of investments. Derivatives could expose the Fund to increased volatility and/or significant loss. Certain derivatives have an inherent leverage component, providing the Fund exposure to a sizable position in an underlying asset with a relatively small upfront investment at the time the Fund enters into the derivatives position. For these derivatives, an adverse change in the value or price of the underlying asset could result in a loss substantially greater than the amount invested in the derivative itself. Some derivatives require the Fund to enter into a contract with a counterparty. If the counterparty is unable or unwilling to fulfill its contractual obligation, the Fund may experience a loss. A liquid market may not always exist for the Fund’s derivatives positions. The Fund may be unable to sell or otherwise exit its derivatives position at desired times or prices, which could also result in a loss to the Fund. Some derivatives, particularly OTC derivatives, can be complex and often are valued subjectively. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the Fund.

Derivatives may not perform as intended, which may result in losses to the Fund. For example, derivatives used for hedging or as a substitute for a portfolio instrument may not provide the expected benefits, particularly during adverse market conditions. The use of derivatives is also subject to legal risk, which includes the risk of loss resulting from insufficient or unenforceable contractual documentation, insufficient capacity or authority of the Fund’s counterparty, and operational risk, which includes documentation or settlement issues, system failures, inadequate controls, and human error.

Ownership Limitations Risk. As the Vanguard funds continue to grow, they may be increasingly impacted by ownership limitations that apply to certain securities held by the Vanguard funds (“limited securities”). An ownership limitation restricts the amount of a security that funds within the same fund complex or funds advised by the same investment advisor can own. These limitations may apply even where an external manager or different affiliate of Vanguard provides investment advisory services to a fund. Ownership limitations restrict the amount that funds can invest in certain securities, due to either regulatory limits that apply to certain industries (for example, banking and utilities) or mechanisms that some issuers have in place to deter takeover attempts (for example, poison pills). These restrictions can have negative impacts on funds, including the inability of an index fund to track its index, the inability of a fund to meet its investment objectives, negative performance impacts, and unanticipated tax consequences. The impact of a particular ownership limitation on a Vanguard fund will vary based on several factors, including, but not limited to, a fund’s investment strategy and its current and desired exposure to limited securities, the industry to which the limitation applies, the country or region of a particular issuer, and the regulatory body imposing the limitation. In addition to the impacts of specific ownership limitations, the Vanguard funds are also subject to the risk of multiple ownership limitations applying at one time, which could increase the likelihood of a fund experiencing the negative impacts listed above. The Vanguard funds attempt to mitigate the impacts of ownership limitations through the various methods discussed below in Methods to address ownership limitations. However, it is possible that these methods will be unsuccessful and could also expose the Vanguard funds to other potential risks and negative consequences.

Impacts of ownership limitations. When an ownership limitation applies, the Vanguard funds may need to allocate ownership of impacted securities across impacted Vanguard funds, and a Vanguard fund may not be able to buy additional securities or continue to hold existing securities above its allocated amounts. For index funds, this can result in tracking error if a fund cannot buy or hold the securities it needs in order to replicate or sample its target index. For active funds, this can result in a fund not being able to take advantage of favorable opportunities to invest in securities that are subject to limitations. For both index and active funds, the inability to buy or hold securities could prevent a fund from being able to meet its investment objective or invest in accordance with its investment strategy, and/or could negatively impact the fund’s performance. In addition, the steps taken to address ownership limitations could result in additional costs and/or unanticipated tax consequences to a fund that affect the amount, timing, and character of distributions to the fund’s shareholders. The more assets the Vanguard funds hold, the more likely it is that ownership limitations will negatively impact Vanguard funds because they will not be able to purchase additional shares of limited securities above their allocated amounts in order to fully invest their assets in accordance with their investment strategies.

Methods to address ownership limitations. The Vanguard funds try to manage the negative impacts of these ownership limitations on the Vanguard funds by

seeking permission (relief) from regulators and/or issuers to purchase or hold more securities than the amount allowed by ownership limitations. However, it is not always possible to secure relief and such relief could be revoked if the Vanguard funds are unable to satisfy the applicable conditions, or it the regulator or issuer changes its position or policy or if the applicable legal requirements become more restrictive. There is an increasing amount of uncertainty around how much ownership limitations relief regulators will grant to asset managers like Vanguard. Given this uncertainty, there is no guarantee that Vanguard or the Vanguard funds will be able to maintain their existing relief or obtain additional relief from ownership limitations in the future. A regulator may impose certain conditions on the Vanguard funds in connection with granting relief from an ownership limitation, including, for example, that the funds vote in a certain way with respect to shares of the limited security that the Vanguard funds hold in excess of the ownership limitation.

In addition, the relief upon which Vanguard and the Vanguard funds currently rely, which has allowed Vanguard to exceed certain ownership limitations, could be reduced or revoked, forcing the Vanguard funds to sell down one or more securities to comply with the ownership limitations. If a fund has to sell securities, there could be negative impacts to fund performance as well as unanticipated tax consequences that could impact the amount, timing, and character of distributions to the fund’s shareholders.

When a Vanguard fund cannot buy or hold securities directly due to ownership limitations, the fund will typically try to get indirect exposure to impacted securities. The fund does this so that it can replicate as closely as possible the returns the fund would get if it directly owned the impacted securities. Indirect exposure can be accomplished through the use of derivatives, such as total return swaps, or by investing in wholly owned subsidiaries that hold the impacted securities. Both of these methods of obtaining indirect exposure increase fund costs, and, depending on the extent to which these alternatives are used by a fund to avoid exceeding ownership limits, the added costs could have a negative impact on the fund’s performance. With respect to an index fund, these added costs could also result in tracking error relative to the fund’s target index. The risks associated with derivatives use are discussed in more detail elsewhere in the prospectus.

There is no guarantee that laws and regulations always will allow that indirect exposure to limited securities may be omitted for purposes of determining the Vanguard funds’ exposure to limited securities and compliance with the applicable ownership limitations. In such circumstances, the Vanguard funds could not use these techniques and would be required to sell down the indirect and/or direct holdings in the applicable limited securities.

Other Investment Policies

In addition to employing its principal investment strategies, the Fund may use the following other investment strategies and types of investments in order to achieve its investment objective.

Substitute Index

The Fund reserves the right to substitute a different index for the index it currently tracks if the current index is discontinued, if the Fund’s agreement with the provider of its Target Index is terminated, or for any other reason determined in good faith by the Board. In any such instance, the substitute index would represent the same market segment as the Target Index.

Other Types of Investments

In most cases, the Fund invests directly in the components of its Target Index. However, the Fund also reserves the right to obtain indirect economic exposure to an index component by purchasing a depositary receipt representing an interest in that component. Depositary Receipts, also sold as participatory notes, are securities that are listed on exchanges or quoted in over-the-counter markets in one country, but represent shares of issuers domiciled in another country. Generally, the Fund will purchase depositary receipts only when the advisor believes that the Fund would benefit from holding the depositary receipt rather than the underlying index component. For example, the Fund might opt to hold a depositary receipt if the foreign market in which an index component trades does not provide adequate protection to the rights of foreign investors, or if a foreign regulator places restrictions on the free flow of capital or currency. For purposes of any investment policy or other requirement related to the percentage of index components held by the Fund, depositary receipts that represent an interest in an index component are treated by the Fund as index components.

The Fund may invest in derivatives such as total return swaps, equity futures, foreign currency exchange forward contracts, or other derivatives. In general, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. The Fund may use derivatives to obtain exposure to a stock, a basket of stocks, or an index. Derivatives may also be used as an alternate means to obtain economic exposure if the Fund is required to limit its investment in a particular issuer or industry. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

A foreign currency exchange forward contract is an agreement to buy or sell a currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. In other words, the contract guarantees an exchange rate on a given date. Advisors of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in currency rates. These contracts, however, would not prevent the Fund’s securities from falling in value as a result of risks other than unfavorable currency exchange movements. The Fund may use these contracts to manage currency exposure and to settle trades in a foreign currency.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are used as cash management vehicles for the Vanguard funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.

Temporary Defensive Measures

The Fund may temporarily depart from its normal investment policies and strategies when the advisor believes that doing so is in the Fund’s best interest, so long as the strategy or policy employed is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond its normal limits in derivatives or exchange-traded funds that are consistent with the Fund’s investment objective when those instruments are favorably priced or provide needed liquidity, as might be the case when the Fund receives large cash flows that it cannot prudently invest immediately. The Fund may also invest beyond its normal limits in derivatives as an alternative means to obtain economic exposure if the Fund is required to limit its investment in a particular issuer or industry.

Portfolio Holdings

Please consult the Fund’s Statement of Additional Information or Vanguard’s website for a description of the policies and procedures that govern disclosure of the Fund’s portfolio holdings.

Management and Distribution of the Fund

The Fund is a member of The Vanguard Group, Inc. (Vanguard), a family of over 200 funds. All of the funds that are members of Vanguard (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

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

How Is Vanguard’s Corporate Structure Unique?

Vanguard is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that are owned by third parties—either public or private stockholders—and not by the funds they serve.

Investment Advisor

The Vanguard Group, Inc., P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Equity Index Group. As of XX XX, 20XX, Vanguard served as advisor for approximately $xx trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds’ Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.

Although the Fund is managed solely by Vanguard, the Fund reserves the right to utilize a multimanager approach in the future. Under the terms of an SEC exemption, the Board may, without prior approval from shareholders, change the terms of an advisory agreement with a third-party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund’s advisory arrangement will be communicated to shareholders in writing. As the Fund’s sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the Board that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking an SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.

For a discussion of why the Board approved the Fund’s investment advisory arrangement, see the Financial Statements and Other Information following the commencement of operations.

The managers primarily responsible for the day-to-day management of the Fund are:

Nicole Brubaker, Portfolio Manager at Vanguard. She has been with Vanguard since 2014, has worked in investment management since 2018, and has co- managed the Fund since its inception in XX 20XX. Education: B.S., Millersville University.

Christine D. Franquin, Principal of Vanguard. She has managed investment portfolios since joining Vanguard in 2000 and has co-managed the Fund since its inception in XX 20XX. Education: B.A., Universitaire Faculteiten Sint-Ignatius Antwerpen, Belgium; J.D., University of Liege, Belgium; M.S., Clark University.

Jeffrey D. Miller, Portfolio Manager at Vanguard. He has been with Vanguard since 1999, has managed investment portfolios since 2010, and has co- managed the Fund since its inception in XX 20XX. Education: B.A., The Pennsylvania State University; M.B.A., Drexel University.

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

Investing in Vanguard ETF® Shares

The Fund’s ETF shares are listed for trading on XX. You can buy and sell ETF shares on the secondary market in the same way you buy and sell any other exchange-traded security—through a broker. Your broker may charge a commission to execute a transaction. Unless imposed by your broker, there is no minimum dollar amount you must invest and no minimum number of ETF shares you must buy.

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 ensuring that you receive income and capital gains distributions, as well as 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.

Redemption of ETF Shares by Authorized Participants

Unlike conventional (i.e., not exchange-traded) mutual fund shares, ETF shares cannot be purchased directly from or redeemed directly with the issuing fund by an individual investor. Instead, only Authorized Participants can purchase and redeem ETF shares directly from the issuing fund. Authorized Participants may purchase and redeem ETF shares from the issuing fund only in large blocks (creation units), usually in exchange for baskets of securities. Funds may also issue and redeem creation units in exchange for solely cash or a combination of cash and securities. These trades may occur in-kind between Vanguard and the Authorized Participant. If cash is used to meet redemptions, the Fund typically obtains such cash through positive cash flows or the sale of Fund holdings consistent with the Fund’s investment objective and strategy.

Under certain circumstances, including under stressed market conditions, a Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility; through a bank line-of-credit, including a joint committed credit facility; or through an uncommitted line-of-credit from Vanguard in order to meet redemption requests.

Pricing of Fund Shares

ETF shares may only be bought and sold in the secondary market. The price you pay or receive for the ETF shares will be the prevailing market price, which may be more or less than the Fund’s NAV. Your transaction will be priced at the NAV only if you purchase or redeem your ETF shares in creation unit blocks (an option available only to certain authorized broker-dealers). NAV is typically calculated as of the close of regular trading on the New York Stock Exchange (“NYSE”), generally 4 p.m., Eastern time, on each day that the NYSE is open for

business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, NAVs will be calculated as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard’s discretion), generally 4 p.m., Eastern time. The time selected for NAV calculation in this rare event generally shall also serve as the conclusion of the trading day. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Vanguard funds do not sell or redeem shares. However, on those days the value of a fund’s assets may be affected to the extent that the securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

If a fund only has one share class, the NAV per share is computed by dividing the total assets, minus liabilities, of a fund by the number of fund shares outstanding. If a fund has more than one share class, each share class has its own NAV, which is computed by dividing the total assets, minus liabilities, allocated to the share class by the number of fund shares outstanding for that class. The value of securities and other investments held by the Vanguard funds is determined pursuant to the valuation policies and procedures adopted by the Vanguard funds’ board of trustees. Vanguard has been designated as the valuation designee for the Vanguard funds pursuant to Rule 2a-5 under the Investment Company Act of 1940, subject to oversight by the Vanguard funds’ board of trustees.

Securities for which market quotations are readily available are valued at their market value, based on quotations provided by independent third-party pricing sources. Such securities are generally valued at their official closing price, the last reported sales price, or if there were no sales that day, the mean between the closing bid and asking prices, from the principal exchange or market on which they are traded. A fund’s investments in any mutual fund shares, including institutional money market fund shares, are valued at the NAVs of the mutual fund shares. A fund’s investments in any ETF shares or closed-end fund shares are valued at the market value of those shares.

When the market quotations are not readily available or do not accurately reflect the value of a security or other investment, such security or other investment is priced at fair value, generally based on information provided by independent third-party pricing services, in accordance with the valuation policies and procedures adopted by the Vanguard funds’ board of trustees. Fair value represents a good faith determination of the value of a fund’s investments. The fair value of a security or other investment is the amount that the owner might reasonably expect to receive upon the current sale of the security or other investment. Fair-value pricing may require subjective determinations. It is possible that the price determined through fair-value pricing may differ from the price quoted or published by other sources and may not be the price at which those investments could have been sold during the period in which the fair value was used.

Fair-value pricing may be used in a variety of circumstances. For example, it may be used if the value of a security or other investment has been materially affected by events occurring after the close of the principal exchange or market on which the security is traded but before the funds’ NAV is calculated. These events might be company-specific (e.g., earnings report, merger announcement), country-specific (e.g., significant price movements in U.S. or a foreign market), or regional/global events (e.g., natural disaster, economic or political news, interest rate change, act of terrorism). These events could affect a single security or a large number of securities in a particular market, and it most commonly occurs with foreign portfolio holdings because many foreign markets operate at times that do not coincide with those of the major U.S. markets. Events that could affect the value of the foreign portfolio holdings may occur between the close of the foreign market and the time a fund’s NAV is calculated. The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of regular trading on the NYSE.

In addition, fair-value pricing may be used if trading in a security is halted and does not resume before a fund’s pricing time, a security does not trade in the course of a day and a fund holds enough of the security that its price could affect the NAV, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available.

Fixed income securities are generally valued based on information furnished by independent pricing services and are priced at fair value. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

Failures by third-party pricing services to carry out their obligations to the Vanguard funds (e.g., any errors in the data provided by third-party pricing services) could result in delays in the calculation of the funds’ NAVs and/or the inability to calculate the NAVs over extended time periods. The funds may be unable to recover any losses associated with such failures.

The Vanguard funds have authorized certain financial intermediaries and their designees, and may, from time to time, authorize certain funds of funds for which Vanguard serves as the investment advisor (Vanguard Funds of Funds), to accept orders to purchase or redeem fund shares on behalf of the Vanguard funds. In these circumstances, the Vanguard fund will be deemed to receive an order when accepted by the authorized financial intermediary, its designee, or one of the Vanguard Funds of Funds, and the order will be executed using the NAV next calculated after such acceptance.

Vanguard’s website will show the previous day’s closing NAV and closing market price for the fund’s ETF shares. The website also discloses, in the Premium/Discount analysis section of a fund’s Price and Performance page,

how frequently the fund traded at a premium or discount to NAV (based on closing NAVs and market prices) and the magnitudes of such premiums and discounts.

Dividends, Distributions, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest less expenses) as well as any net short-term or long-term capital gains realized from the sale of its holdings. The Fund may also make distributions that are treated as a return of capital. Income dividends generally are distributed quarterly in March, June, September, and December; capital gains distributions, if any, generally occur annually in December. In addition, the Fund may make a supplemental distribution at some other time during the year.

From time to time, Vanguard and/or a fund’s board of trustees may adjust a fund’s fees and expenses and/or reduce, refund, reimburse, waive, or otherwise return to the funds and their shareholders a portion of prior fees and expenses (collectively, “expense adjustments”). Fund performance and potentially shareholder distributions, will reflect such expense adjustments. If you sell all or part of your investment in a fund before an expense adjustment occurs, then you will not receive the economic benefit, if any, of such expense adjustment. An expense adjustment at any given time does not imply or guarantee that similar or additional expense adjustments will be made in the future.

Reinvestment of Distributions

In order to reinvest dividend and capital gains distributions, investors in the Fund’s ETF shares must hold their shares at a broker that offers a reinvestment service. This can be the broker’s own service or a service made available by a third party, such as the broker’s outside clearing firm or the Depository Trust Company (DTC). If a reinvestment service is available, distributions of income and capital gains can automatically be reinvested in additional whole and fractional ETF shares of the Fund. If a reinvestment service is not available, investors will receive their distributions in cash. To determine whether a reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker.

As with all exchange-traded funds, reinvestment of dividend and capital gains distributions in additional ETF shares will occur two business days or more after the ex-dividend date (the date when a distribution of dividends or capital gains is deducted from the price of the Fund’s shares). The exact number of days depends on your broker. During that time, the amount of your distribution will not be invested in the Fund and therefore will not share in the Fund’s income, gains, and losses.

Basic Tax Points

Investors in taxable accounts should be aware of the following basic federal income tax points:

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

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

•Any income dividend distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income.

•Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned shares in the fund.

•Income and capital gains distributions may vary considerably from month to month or year to year, as applicable, as a result of the Fund’s normal investment activities and cash flows.

•Capital gains distributions may occur if Vanguard, the Fund, or its advisor makes changes that would impact the Fund directly or indirectly, including changes to the Fund’s portfolio or advisors or changes to any other Vanguard fund or product that would involve the redemption of shares of the Fund and the related sale of the Fund’s investments. Such changes could, depending on the timing, result in capital gains distributions in the current fiscal year, subsequent fiscal year, or both.

•Your cost basis in the Fund will be decreased by the amount of any return of

capital that you receive. This, in turn, will affect the amount of any capital gain or loss that you realize when selling your shares in the Fund.

•Return of capital distributions generally are not taxable to you until your cost basis has been reduced to zero. If your cost basis is at zero, return of capital distributions will be treated as capital gains.

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

•If you purchase shares before an ex-dividend date when a fund has realized but not yet distributed income or capital gains, the purchase price may include the amount of the upcoming distribution, and you may pay the full price for the shares and later receive a portion of the purchase price back as a taxable distribution. In such case, you generally will be taxed upon receipt of such distribution, even though the distribution effectively represents a return of a portion of your purchase price. This is known as “buying a dividend.”

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

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

The Fund may be subject to foreign taxes or foreign tax withholding on dividends, interest, and capital gains from foreign securities. If, at the end of the taxable year, more than 50% of the value of the Fund’s assets consists of securities of foreign corporations, and the Fund makes a special election, you will generally be required to include in your income, for U.S. federal income tax purposes, your share of the qualifying foreign income taxes paid by the Fund in respect of its foreign portfolio securities. There is no assurance that the Fund will make this election for a taxable year, even if it is eligible to do so. You may qualify for an offsetting credit or deduction under U.S. tax laws for any amount designated as your portion of the Fund’s foreign tax obligations, provided that you meet certain requirements. See your tax advisor or IRS publications for more information.

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

Frequent Trading Limitations

Unlike frequent trading of a Vanguard fund’s conventional share classes, frequent trading of ETF shares generally does not disrupt portfolio management or otherwise harm fund shareholders. The vast majority of trading in ETF shares occurs on the secondary market. Because these trades do not involve the issuing fund, they do not pose potential harm to the fund or its shareholders. Certain broker-dealers are authorized to purchase and redeem ETF shares directly with the issuing fund. Because these trades typically are effected in kind (i.e., for securities and not for cash), or are assessed a transaction fee when effected in cash, they do not cause any of the harmful effects to the issuing fund (as previously noted) that may result from frequent trading. For these reasons, the Board of each Fund that issues ETF shares has determined that it is not necessary to adopt policies and procedures to detect and deter frequent trading and market-timing of ETF shares.

Additional Information

A precautionary note to investment companies. The Fund’s shares are issued by a registered investment company, and therefore the acquisition of such shares by other investment companies and private funds is subject to the restrictions of Section 12(d)(1) of the Investment Company Act of 1940 (the 1940 Act). SEC Rule 12d1-4 under the 1940 Act permits registered investment companies to invest in other registered investment companies beyond the limits in Section 12(d)(1), subject to certain conditions, including that funds with different investment advisors must enter into a fund of funds

investment agreement.

Forum selection. The Trust’s Bylaws designate Delaware courts as the exclusive forum for certain claims against or related to the Trust, a trustee, an officer, or other employee of the Trust, except that, unless the Trust otherwise consents in writing, the U.S. Federal District Courts are the exclusive forum for the resolution of complaints under the Securities Act of 1933 or the 1940 Act. These provisions may limit a shareholder’s ability to bring a claim in a different forum and may result in increased shareholder costs in pursuing such a claim.

Shareholder rights. The Fund’s Agreement and Declaration of Trust, as amended, requires a shareholder bringing a derivative action on behalf of the Trust that is subject to a pre-suit demand to collectively hold at least 10% of the outstanding shares of the Trust or at least 10% of the outstanding shares of the series or class to which the demand relates and to undertake to reimburse the Trust for the expense of any counsel or advisors used when considering the merits of the demand in the event that the board of trustees determines not to bring such action. In each case, these requirements do not apply to claims arising under the federal securities laws to the extent that any such federal securities laws, rules, or regulations do not permit such application. The Trust’s Bylaws also provide that shareholders waive the right to trial by jury to the fullest extent permitted by law.

Joint committed credit facility. The Fund participates, along with other funds managed by Vanguard, in a committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each Vanguard fund is individually liable for its borrowings, if any, under the credit facility. The amount and terms of the committed credit facility are subject to approval by the Board and renegotiation with the lender syndicate on an annual basis.

Certain affiliates of the Fund and the advisor may purchase and resell ETF shares pursuant to the prospectus.

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

Fund Summary

Investment Objective

Vanguard Developed Markets ex-US Value Index ETF (the “Fund”) seeks to track the performance of a benchmark index that measures the investment return of large- and mid-cap value stocks issued by companies located in developed market countries, excluding the United States.

Fees and Expenses

The following tables describe the fees and expenses you may pay if you buy, hold, and sell ETF shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below.

Shareholder Fees

(Fees paid directly from your investment)

*None through Vanguard (Broker fees vary)

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

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 pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund has no operating history and therefore has no portfolio turnover information.

Principal Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the S&P Developed Ex-U.S. LargeMidCap Value Index, (the “Target Index”), a float-adjusted market capitalization-weighted index that is made up of common stocks of large- and mid-cap value companies located in developed markets countries, excluding the United States. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in stocks that make up the Target Index. The Fund attempts to replicate the Target Index by seeking to invest all, or substantially all, of its assets in the stocks that make up the Target Index, in order to hold each stock in approximately the same proportion as its weighting in the Target Index.

Principal Risks

As with any investment, an investment in the Fund could lose money over any time period. The Fund’s share price and total return may fluctuate, potentially within a wide range. The principal risks of investing in the Fund are summarized below. Each of the following risks could affect the Fund’s performance:

•General Market Risk. The markets in which the Fund invests can be affected by a variety of factors. These factors, which can be real or perceived, may

include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund’s investments, thereby resulting in potential losses to the Fund over short or long periods.

•Investing in Foreign Markets. Foreign markets can perform differently than U.S. markets. World events could adversely affect the value and/or liquidity of securities of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund’s performance may be hurt disproportionately by the poor performance of its investments in such country or region.

•Currency Risk. The Fund is subject to the risk that foreign currency will perform differently than U.S. dollars and increase the potential loss to the Fund. Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund. Changes in currency exchange rates can affect the value of the Fund’s holdings.

•Investing in Equity Markets. The Fund invests in the equity markets. Equity markets have historically been cyclical, having periods of time when stock values rise and fall. Market volatility can lead to significant fluctuations in stock values, resulting in potential losses to the Fund.

•Market Capitalization (Market Cap). Companies are generally classified into three types of market cap depending on their size: small-, mid-, and large- cap. Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid- cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a

subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.

•Value Investing. The Fund’s approach to value investing could cause it to underperform other stock funds that use a different investment style. The Fund’s investments in value stocks are subject to the risk that the stocks’ valuations never improve or that their returns do not move in tandem with the returns of other investment styles or the broader stock market.

•Index Investing. The Fund is subject to risks associated with index investing. Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund’s performance may be lower than it would be if it were actively managed. Although the Fund seeks to hold substantially all of the securities included in the Target Index, it may be unable to do so. In addition, the Fund could be prevented from holding one or more securities in the same proportion as in the Target Index. The performance of the Fund’s investments, in the aggregate, may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the Index Provider or by errors made by the Index Provider. Any gains, losses, or costs associated with or resulting from an error made by the Index Provider will generally be borne by the Fund and, as a result, the Fund’s shareholders.

•Concentration Risk. Except as may be necessary to approximate the composition of its Target Index, the Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry or group of industries. If the Target Index becomes concentrated and the Fund needs to concentrate in the same industry or group of industries, its performance could be negatively impacted by the industry or industries in which it is concentrated.

•ETF Share Trading. The Fund’s ETF shares are listed for trading on XX and individual investors may only buy and sell them on the secondary market at market prices. Although it is expected that the market price of an ETF share typically will approximate its net asset value (NAV), there may be times when the market price of an ETF share and its NAV differ significantly. Disruptions to creation and redemption transactions, the existence of significant market volatility or potential lack of an active trading market for ETF shares (including through a trading halt), as well as other factors, may result in ETF shares trading significantly above (at a premium) or below (at a discount) the Fund’s NAV or the intraday value of the Fund’s holdings. Thus, you may pay more or less than NAV when you buy ETF shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

•Authorized Participants. Only Authorized Participants may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that may act as Authorized Participants. The Fund’s Authorized Participants are not obligated to engage in creation or redemption transactions. To the extent that the Fund’s Authorized Participants are unable to or choose not to proceed with creation and/or redemption transactions with respect to the Fund and no other Authorized Participants step forward to engage in creation or redemption transactions with the Fund, the Fund’s ETF shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

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.

Purchase and Sale of Fund Shares

ETF shares may only be bought and sold in the secondary market through a brokerage firm. The price you pay or receive for ETF shares will be the prevailing market price, which may be more (premium) or less (discount) than the NAV of the shares. The brokerage firm may charge you a commission to execute the transaction. Unless imposed by your brokerage firm, there is no minimum dollar amount you must invest and no minimum number of shares you must buy. ETF shares of the Fund cannot be directly purchased from or redeemed with the Fund, except by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF shares only in large blocks known as creation units, typically in exchange for baskets of securities.

An investor in ETF shares may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF shares (bid) and the

lowest price a seller is willing to accept for ETF shares (ask) when buying or selling shares in the secondary market (bid-ask spread). Recent information about the Fund and its ETF shares, including information on the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available online at vanguard.com.

Tax Information

The Fund’s distributions may be taxable as ordinary income or capital gains. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. You should consult your own tax advisor with respect to any particular U.S. or non- U.S. tax consequences of your investment in the Fund.

Payments to Financial Intermediaries

The Fund and its advisor do not pay financial intermediaries for sales of Fund shares.

More on the Fund

This prospectus provides information about Vanguard Developed Markets ex- US Value Index ETF, an exchange-traded fund (the “Fund”). The Fund is a series of Vanguard World Fund (the “Trust”). Unlike conventional mutual fund shares, ETF shares cannot be purchased directly from or redeemed directly with the issuing fund by an individual investor. Instead, only certain authorized broker-dealers (“Authorized Participants”) can purchase and redeem ETF shares directly from the issuing fund at net asset value. Authorized Participants may purchase and redeem ETF shares from the issuing fund only in large blocks (creation units), usually in exchange for baskets of securities. Funds may also issue and redeem creation units in exchange for solely cash or a combination of cash and securities. These trades may occur in-kind between Vanguard and the Authorized Participant. Individual investors can purchase ETF shares on the secondary market through a broker. Reading this prospectus will help you decide whether the Fund is the right investment for you.

As you consider an investment in the Fund’s ETF shares, you should take into account your tolerance for fluctuations in the securities markets. The costs of investing are another important consideration. As a Fund shareholder, you will pay a proportionate share of the costs of operating the Fund and any transaction costs incurred when the Fund buys or sells securities, including costs generated by shareholders of other share classes to the extent the Fund offers more than one share class. These costs can erode a substantial portion of the gross income or the capital appreciation the Fund achieves. Even seemingly small differences can, over time, have a dramatic effect on the Fund’s performance.

Investment Objective and More on Principal Investment Strategies

In this section, you will find more information about the Fund’s investment objective and the principal investment strategies and policies that the Fund uses in pursuit of its investment objective. The Trust’s board of trustees (the “Board”) oversees the Fund’s management. The Board may approve changes to the Fund’s strategies or policies in the interest of shareholders without shareholder approval unless the strategy or policy is designated as fundamental.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of large- and mid-cap value stocks issued by companies located in developed market countries, excluding the United States.

The Fund’s investment objective is not fundamental and may be changed without shareholder approval.

Implementation of Investment Objective

To achieve its investment objective, the Fund employs an indexing, or passive, investment approach designed to track the performance of its Target Index, the S&P Developed Ex-U.S. LargeMidCap Value Index.

What are Index Funds?

Index funds attempt to track—not outperform—the performance of a specified market index. An index is a group of securities whose overall performance is used as a standard to measure the investment performance of a particular market. Some indexes represent entire markets, such as the U.S. stock market, while others cover a segment of a market, such as short- term bonds.

One cannot invest directly in an index. Instead, an index fund’s advisor will typically seek to hold all, or substantially all, of the securities that make up the fund’s target index (often referred to as “replicating” an index or a “full replication” approach) or a representative sample of the securities that make up a fund’s target index (“sampling” an index).

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index. Investments in derivatives may be counted toward the Fund’s 80% policy to the extent that they provide investment exposure to the securities included within the policy or to one or more market risk factors associated with such securities. The Fund may change its 80% policy only upon 60 days’ notice to shareholders.

Security Selection

The Fund uses the replication method of indexing, meaning that the Fund generally holds the same stocks as those in its Target Index and in approximately the same proportions. The advisor buys and sells securities for the Fund for the purpose of tracking the Target Index.

The Fund’s Target Index is a float-adjusted market capitalization-weighted index designed to measure the top 85% of float-adjusted market capitalization in each developed country, excluding the United States. The Target Index is a subset of the S&P Global BMI, a comprehensive rules-based index measuring global stock market performance. The Fund’s Target Index is made up of common stocks of large- and mid-cap value companies from developed markets excluding the United States.

As of XX XX, 20XX, the number of stocks (constituents) in the Target Index was approximately XX. The constituents of the Target Index are reviewed and rebalanced by the Index Provider on an annual basis in September each year and in connection with share changes and IPO updates in March, June and December each year.

The Target Index is owned, calculated, and controlled by the Index Provider in its sole discretion. Neither the advisor nor any of its affiliates has discretion to select Target Index components or change the Target Index’s methodology.

Stocks of publicly traded companies are often classified according to market capitalization, which is the market value of a company’s outstanding shares. These classifications typically include small-cap, mid-cap, and large-cap. It is important to understand that there is no “official” definition of each type of small- cap, mid-cap, or large-cap and that market capitalization ranges can change over time.

The Fund’s median market capitalization, which is the midpoint of the market capitalization of the fund’s stocks weighted by the proportion of the fund’s assets invested in each stock, can be used as an indicator of the size of the companies in which it invests. Stocks representing half of a fund’s assets will have market capitalizations above the median, and the rest will fall below it.

Additional Information Regarding the Fund’s Investments

The Fund’s investments are described in more detail below.

•Large-Cap Stocks represent the largest publicly traded companies, which are often well-established and widely recognized. These companies typically have significant market share, global reach, and a history of financial stability. While they may not offer as much growth potential as smaller companies, they are generally considered more resilient during economic downturns but still not immune from a decrease in price.

•Mid-Cap Stocks represent medium-sized companies, which can be companies that are more established than small-cap companies but do not have the market share of large-cap companies. These companies may be more agile than large-cap companies in responding to market changes, while also benefiting from more resources and operational maturity than small-cap companies. However, they can still face challenges during economic downturns.

•Value Stocks typically represent companies that appear to be undervalued based on financial metrics like price-to-earnings or book value. These stocks are often priced lower relative to their fundamentals, which may reflect temporary challenges, such as recent earnings or negative market sentiment, rather than long-term issues. Value stocks typically offer higher dividend yields than other types of stocks, which can make them attractive to investors seeking income as well as potential price appreciation.

More on Fund Risks

Investing in the securities markets can result in a loss of principal. The Fund is subject to a variety of risks, including the principal risks listed below, that can impact its net asset value (NAV), performance, and ability to achieve its investment objective.

More on Principal Risks

General Market Risk. The markets in which the Fund invests can be affected by a variety of factors. These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund’s investments, thereby resulting in potential losses to the Fund over short or long periods.

Investing in Foreign Markets. Foreign markets can perform differently than U.S. markets. World events could adversely affect the value and/or liquidity of securities (including depositary receipts) of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. The performance of a fund that invests significantly in one or more countries or regions will be closely tied to factors within that country or region. These factors may include currency, economic, political, and/or regulatory conditions and developments. Therefore, the Fund’s performance may be affected disproportionately compared to a fund that does not invest significantly in such countries or regions.

Currency Risk. The Fund is subject to the risk that foreign currency will perform differently than U.S. dollars and increase the potential loss to the Fund. Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund. Changes in currency exchange rates can affect the value of the Fund’s holdings.

Investing in Equity Markets. The Fund invests in the equity markets. Equity markets have historically been cyclical, having periods of time when stock values rise and fall. These periods of rising and falling values can occur for unpredictable timeframes over the short- and long-term. Market volatility also is

unpredictable and can lead to significant fluctuations in stock values, resulting in potential losses to the Fund.

Market Capitalization (Market Cap) – Large-Cap Companies. Large-cap companies are typically more well-established, well-known, and mature companies from an operational perspective than smaller cap companies. Because of this, they may not reach the same levels of growth or performance as smaller cap companies, and they may be slower to react to competitive challenges. The Fund’s focus on large-cap companies could affect its performance relative to a fund that is focused on a broader representation of the stock market.

Market Capitalization (Market Cap) – Mid-Cap Companies. Mid-cap companies fall between large- and small-cap companies in size. Due to being smaller, they may be more affected by adverse business or economic events than larger companies. The Fund’s focus on mid-cap companies could affect its performance relative to a fund that is focused on a broader representation of the stock market.

Value Investing. Companies and their stock are often classified as growth or value. Growth investing and value investing are two investment styles used by advisors. Under certain market conditions these investment styles may perform differently, generating varying returns. The Fund's approach to value investing could cause it to underperform other stock funds that use a different investment style. The Fund’s investments in value stocks are subject to the risk that the stocks’ valuations never improve or that their returns do not move in tandem with the returns of other investment styles or the broader stock market

Index Investing. The Fund is subject to the following risks associated with index investing:

Passive Management. The Fund seeks to track the performance of its Target Index regardless of how the Target Index is performing. The advisor’s use of an indexing, or passive, approach to select and maintain investments for the Fund means that the advisor will select investments for the purpose of tracking the Target Index and generally will not use strategies to reduce negative impacts to the Fund during periods of market volatility. As a result, the Fund’s performance may be lower than it would be if it were actively managed.

Index Replication Strategy. Although the Fund seeks to hold substantially all of the securities included in its Target Index, it may be unable to do so. In addition, the Fund could be prevented from holding one or more of the securities in the same proportion as in the Target Index.

Tracking Error. The performance of the Fund’s investments, in the aggregate, may not match the investment performance of its Target Index. It is important to understand that an index fund will never perform exactly the same as its target index because, among other things, an index fund has operating expenses and transaction costs and its target index does not. Beyond these inherent differences in the operation of an index fund versus the operation of its target

index, there are a variety of other factors that can cause or result in tracking error. These may include, but are not limited to:

oPrice differences between the securities held by the Fund and those included in its Target Index

oCash flows into or out of the Fund o The size of the Fund

o Compliance with new or existing regulatory requirements o Portfolio transactions carried out by the advisor to minimize

the distribution of capital gains

o Changes to the underlying securities that make up the Fund’s Target Index

o Errors made by the Index Provider

Tracking error risk may be heightened during times of increased market volatility or under other unusual market conditions. An index fund using a sampling strategy may be more likely to experience tracking error than an index fund using a replicating strategy.

Index Provider. The Fund is subject to risks associated with its Index Provider. The securities that make up the Target Index and their weighting in the Target Index are determined by the Index Provider. The Index Provider does not provide any warranty or accept any liability with respect to the quality, accuracy, or completeness of the Target Index or any data used to compile the Target Index. Under normal circumstances, the Index Provider rebalances (updates) the Target Index on a regular schedule. However, the Index Provider may also rebalance the Target Index outside of the regular schedule or delay or cancel a scheduled rebalance, which could result in added costs for the Fund or cause the Fund to experience tracking error. The Index Provider may make errors, and it is possible that such errors may not be identified by the Index Provider for a period of time or at all. Any gains, losses, or costs associated with or resulting from an error made by the Index Provider will generally be borne by the Fund and, as a result, the Fund’s shareholders. The Fund’s advisor does not provide any warranty or guarantee against any errors made by the Index Provider.

Concentration Risk. Except as may be necessary to approximate the composition of its Target Index, the Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry or group of industries. However, it is possible that the Target Index could become concentrated due to market conditions or the performance of a single or related group of issuers. If the Target Index becomes concentrated and the Fund needs to concentrate in the same industry or group of industries, its performance could be negatively impacted by the industry or industries in which it is concentrated.

ETF Share Trading. Because ETF shares trade on the secondary markets, they are subject to the following risks:

ETF Shares Trading at Prices Other Than NAV. ETF shares may trade on a national securities exchange at prices above, below or at their most recent NAV. The NAV of a Fund’s ETF shares, which typically is calculated at the end

of each business day, will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of ETF shares will also fluctuate, in some cases materially, in accordance with changes in NAV and the intraday value of a Fund’s holdings, as well as the relative supply of and demand for the ETF shares on an exchange. Differences between secondary market prices of ETF shares and the intraday value of a Fund’s holdings may be due largely to supply and demand forces in the secondary market, which may not be the same forces as those influencing prices for securities held by the Fund at a particular time.

Although it is expected that the market price of an ETF share typically will trade close to the value of a Fund’s holdings, market prices are not expected to correlate exactly to a Fund’s NAV due to timing reasons, supply and demand imbalances, and other factors. In addition, disruptions to creations and redemptions, adverse developments impacting market makers, authorized participants or other market participants, or high market volatility may result in the market price of ETF shares differing significantly from the Fund’s NAV or the intraday value of a Fund’s holdings. As a result of these factors, among others, you may pay more (premium) or less (discount) than NAV when you buy ETF shares on the secondary market, and you may receive more or less than NAV when you sell those shares. These discounts and premiums are likely to be greatest during times of market disruption or extreme market volatility.

Cost of Buying or Selling Shares. Individual investors who buy or sell ETF shares through a broker may incur a brokerage commission or other charges imposed by brokers. In addition, the market price of ETF shares, like the price of any security on an exchange, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The bid- ask spread is the difference between the highest price a buyer is willing to pay to purchase ETF shares (bid) and the lowest price a seller is willing to accept for ETF shares (ask) when buying or selling shares in the secondary market. The bid-ask spread of a Fund’s ETF shares can vary over time based on the Fund’s trading volume and market liquidity and may increase if the Fund’s trading volume, the bid-ask spread of the Fund’s underlying securities, or market liquidity decrease. In times of severe market disruption, including when trading of a Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that ETF shares may trade at a discount to a Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

Short Selling. ETF shares, similar to shares of other issuers listed on an exchange, may be sold short. In a short sale, an investor “borrows” securities from a lender for a fee and then sells the borrowed securities on the open market with the hope that the borrowed securities decline in price before the investor has to repurchase the securities to return them to the lender. Short sales of ETF shares can increase their volatility and lead to price decreases.

Lack of Active Trading Market. Although ETF shares are listed on a national securities exchange, it is possible that an active trading market may not be maintained. Although this could happen at any time, it is more likely to occur

during times of severe market disruption. If you attempt to sell your ETF shares when an active trading market is not functioning, you may have to sell at a significant discount to NAV. In extreme cases, you may not be able to sell your shares at all.

Trading Halt. Trading of ETF shares on an exchange may be halted by the activation of individual or market-wide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of ETF shares may also be halted if (1) the shares are delisted from the listing exchange without first being listed on another exchange or (2) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors. If a trading halt or unanticipated early closing of an exchange occurs, a shareholder may be unable to purchase or sell ETF shares.

Authorized Participants. Only Authorized Participants may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that may act as Authorized Participants. The Fund’s Authorized Participants are not obligated to engage in creation or redemption transactions. To the extent that the Fund’s Authorized Participants are unable to or choose not to proceed with creation and/or redemption transactions with respect to the Fund and no other Authorized Participants step forward to engage in creation or redemption transactions with the Fund, the Fund’s ETF shares may trade at a discount to NAV and possibly face trading halts and/or delisting.

Additional Risks

Geopolitical and Sanctions Risk. Due to growing dependencies between global economies, geopolitical events can negatively affect all securities, markets, and economies. It is possible that events which only impact one geographic area could have negative short- or long-term effects on markets, issuers, and/or exchanges in the United States and other countries.

At times, the United States, other governments, or other supranational bodies (e.g., the United Nations) may impose sanctions on countries and/or entities in response to geopolitical events or other priorities. Compliance with sanctions could impact the Fund, including the Fund’s ability to transact in or obtain exposure to certain foreign securities and assets. Sanctions also could cause significant losses to the Fund’s investments and its performance could be negatively impacted. In lieu of sanctions, companies or specific goods that the company produces could be subjected to trade embargoes or tariffs, which can also affect securities markets and create volatility. So long as sanctions do not prohibit investment in the company or issuer, the Fund typically also would not be prohibited from investing in the affected company or issuer.

Potential Redemption Activity Impacts. The Vanguard funds can be negatively impacted by certain large redemptions. These redemptions could occur due to a single shareholder or multiple shareholders deciding to sell a

large quantity of shares of a fund or a share class of the fund. Large redemptions can occur for many reasons, either as a result of actions taken by the Vanguard funds or their advisors, or as a result of events unrelated to actions taken by the Vanguard funds or their advisors. Actions taken by the Vanguard funds or their advisors could include, but are not limited to, changes to a fund’s advisor(s), changes to a fund’s portfolio manager(s), changes to the composition of a fund’s portfolio, and/or other product changes or launches that, for example, result in shareholders redeeming shares of one fund to purchase shares of another fund or investment vehicle. For a fund of funds, actions taken by the Vanguard funds or their advisors could include a withdrawal from an underlying fund or a change in the allocation to underlying funds. Events unrelated to actions taken by the Vanguard funds or their advisors could include shareholders selling out of a fund in response to market movements or regulatory changes.

A large redemption could adversely affect a fund’s liquidity and NAV. For example, a large redemption could require a fund’s manager to sell portfolio holdings at unplanned or inopportune times. The manager’s sale of these holdings, which is a taxable event, could require the fund to distribute any corresponding capital gains or other taxable income to the fund’s remaining shareholders; see Dividends, Capital Gains, and Taxes for additional information. The increased trading activity could also increase underlying costs for the fund due to commissions paid by the fund.

Investing in Derivatives. Investing in derivatives may present risks different from, and/or greater than, those associated with investing directly in stocks, bonds, or other types of investments. Derivatives could expose the Fund to increased volatility and/or significant loss. Certain derivatives have an inherent leverage component, providing the Fund exposure to a sizable position in an underlying asset with a relatively small upfront investment at the time the Fund enters into the derivatives position. For these derivatives, an adverse change in the value or price of the underlying asset could result in a loss substantially greater than the amount invested in the derivative itself. Some derivatives require the Fund to enter into a contract with a counterparty. If the counterparty is unable or unwilling to fulfill its contractual obligation, the Fund may experience a loss. A liquid market may not always exist for the Fund’s derivatives positions. The Fund may be unable to sell or otherwise exit its derivatives position at desired times or prices, which could also result in a loss to the Fund. Some derivatives, particularly OTC derivatives, can be complex and often are valued subjectively. Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the Fund.

Derivatives may not perform as intended, which may result in losses to the Fund. For example, derivatives used for hedging or as a substitute for a portfolio instrument may not provide the expected benefits, particularly during adverse market conditions. The use of derivatives is also subject to legal risk,

which includes the risk of loss resulting from insufficient or unenforceable contractual documentation, insufficient capacity or authority of the Fund’s counterparty, and operational risk, which includes documentation or settlement issues, system failures, inadequate controls, and human error.

Ownership Limitations Risk. As the Vanguard funds continue to grow, they may be increasingly impacted by ownership limitations that apply to certain securities held by the Vanguard funds (“limited securities”). An ownership limitation restricts the amount of a security that funds within the same fund complex or funds advised by the same investment advisor can own. These limitations may apply even where an external manager or different affiliate of Vanguard provides investment advisory services to a fund. Ownership limitations restrict the amount that funds can invest in certain securities, due to either regulatory limits that apply to certain industries (for example, banking and utilities) or mechanisms that some issuers have in place to deter takeover attempts (for example, poison pills). These restrictions can have negative impacts on funds, including the inability of an index fund to track its index, the inability of a fund to meet its investment objectives, negative performance impacts, and unanticipated tax consequences. The impact of a particular ownership limitation on a Vanguard fund will vary based on several factors, including, but not limited to, a fund’s investment strategy and its current and desired exposure to limited securities, the industry to which the limitation applies, the country or region of a particular issuer, and the regulatory body imposing the limitation. In addition to the impacts of specific ownership limitations, the Vanguard funds are also subject to the risk of multiple ownership limitations applying at one time, which could increase the likelihood of a fund experiencing the negative impacts listed above. The Vanguard funds attempt to mitigate the impacts of ownership limitations through the various methods discussed below in Methods to address ownership limitations. However, it is possible that these methods will be unsuccessful and could also expose the Vanguard funds to other potential risks and negative consequences.

Impacts of ownership limitations. When an ownership limitation applies, the Vanguard funds may need to allocate ownership of impacted securities across impacted Vanguard funds, and a Vanguard fund may not be able to buy additional securities or continue to hold existing securities above its allocated amounts. For index funds, this can result in tracking error if a fund cannot buy or hold the securities it needs in order to replicate or sample its target index. For active funds, this can result in a fund not being able to take advantage of favorable opportunities to invest in securities that are subject to limitations. For both index and active funds, the inability to buy or hold securities could prevent a fund from being able to meet its investment objective or invest in accordance with its investment strategy, and/or could negatively impact the fund’s performance. In addition, the steps taken to address ownership limitations could result in additional costs and/or unanticipated tax consequences to a fund that affect the amount, timing, and character of distributions to the fund’s shareholders. The more assets the Vanguard funds hold, the more likely it is that ownership limitations will negatively impact Vanguard funds because they will not be able to purchase additional shares of limited securities above their

allocated amounts in order to fully invest their assets in accordance with their investment strategies.

Methods to address ownership limitations. The Vanguard funds try to manage the negative impacts of these ownership limitations on the Vanguard funds by seeking permission (relief) from regulators and/or issuers to purchase or hold more securities than the amount allowed by ownership limitations. However, it is not always possible to secure relief and such relief could be revoked if the Vanguard funds are unable to satisfy the applicable conditions, or it the regulator or issuer changes its position or policy or if the applicable legal requirements become more restrictive. There is an increasing amount of uncertainty around how much ownership limitations relief regulators will grant to asset managers like Vanguard. Given this uncertainty, there is no guarantee that Vanguard or the Vanguard funds will be able to maintain their existing relief or obtain additional relief from ownership limitations in the future. A regulator may impose certain conditions on the Vanguard funds in connection with granting relief from an ownership limitation, including, for example, that the funds vote in a certain way with respect to shares of the limited security that the Vanguard funds hold in excess of the ownership limitation.

In addition, the relief upon which Vanguard and the Vanguard funds currently rely, which has allowed Vanguard to exceed certain ownership limitations, could be reduced or revoked, forcing the Vanguard funds to sell down one or more securities to comply with the ownership limitations. If a fund has to sell securities, there could be negative impacts to fund performance as well as unanticipated tax consequences that could impact the amount, timing, and character of distributions to the fund’s shareholders.

When a Vanguard fund cannot buy or hold securities directly due to ownership limitations, the fund will typically try to get indirect exposure to impacted securities. The fund does this so that it can replicate as closely as possible the returns the fund would get if it directly owned the impacted securities. Indirect exposure can be accomplished through the use of derivatives, such as total return swaps, or by investing in wholly owned subsidiaries that hold the impacted securities. Both of these methods of obtaining indirect exposure increase fund costs, and, depending on the extent to which these alternatives are used by a fund to avoid exceeding ownership limits, the added costs could have a negative impact on the fund’s performance. With respect to an index fund, these added costs could also result in tracking error relative to the fund’s target index. The risks associated with derivatives use are discussed in more detail elsewhere in the prospectus.

There is no guarantee that laws and regulations always will allow that indirect exposure to limited securities may be omitted for purposes of determining the Vanguard funds’ exposure to limited securities and compliance with the applicable ownership limitations. In such circumstances, the Vanguard funds could not use these techniques and would be required to sell down the indirect and/or direct holdings in the applicable limited securities.

Other Investment Policies

In addition to employing its principal investment strategies, the Fund may use the following other investment strategies and types of investments in order to achieve its investment objective.

Substitute Index

The Fund reserves the right to substitute a different index for the index it currently tracks if the current index is discontinued, if the Fund’s agreement with the provider of its Target Index is terminated, or for any other reason determined in good faith by the Board. In any such instance, the substitute index would represent the same market segment as the Target Index.

Other Types of Investments

In most cases, the Fund invests directly in the components of its Target Index. However, the Fund also reserves the right to obtain indirect economic exposure to an index component by purchasing a depositary receipt representing an interest in that component. Depositary Receipts, also sold as participatory notes, are securities that are listed on exchanges or quoted in over-the-counter markets in one country, but represent shares of issuers domiciled in another country. Generally, the Fund will purchase depositary receipts only when the advisor believes that the Fund would benefit from holding the depositary receipt rather than the underlying index component. For example, the Fund might opt to hold a depositary receipt if the foreign market in which an index component trades does not provide adequate protection to the rights of foreign investors, or if a foreign regulator places restrictions on the free flow of capital or currency. For purposes of any investment policy or other requirement related to the percentage of index components held by the Fund, depositary receipts that represent an interest in an index component are treated by the Fund as index components.

The Fund may invest in derivatives such as total return swaps, equity futures, foreign currency exchange forward contracts, or other derivatives. In general, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. The Fund may use derivatives to obtain exposure to a stock, a basket of stocks, or an index. Derivatives may also be used as an alternate means to obtain economic exposure if the Fund is required to limit its investment in a particular issuer or industry. The Fund will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

A foreign currency exchange forward contract is an agreement to buy or sell a currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. In other words, the contract guarantees an exchange rate on a given date.

Advisors of funds that invest in foreign securities can use these contracts to guard against unfavorable changes in currency rates. These contracts, however, would not prevent the Fund’s securities from falling in value as a result of risks other than unfavorable currency exchange movements. The Fund may use these contracts to manage currency exposure and to settle trades in a foreign currency.

Cash Management

The Fund’s daily cash balance may be invested in one or more Vanguard CMT Funds, which are used as cash management vehicles for the Vanguard funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.

Temporary Defensive Measures

The Fund may temporarily depart from its normal investment policies and strategies when the advisor believes that doing so is in the Fund’s best interest, so long as the strategy or policy employed is consistent with the Fund’s investment objective. For instance, the Fund may invest beyond its normal limits in derivatives or exchange-traded funds that are consistent with the Fund’s investment objective when those instruments are favorably priced or provide needed liquidity, as might be the case when the Fund receives large cash flows that it cannot prudently invest immediately. The Fund may also invest beyond its normal limits in derivatives as an alternative means to obtain economic exposure if the Fund is required to limit its investment in a particular issuer or industry.

Portfolio Holdings

Please consult the Fund’s Statement of Additional Information or Vanguard’s website for a description of the policies and procedures that govern disclosure of the Fund’s portfolio holdings.

Management and Distribution of the Fund

The Fund is a member of The Vanguard Group, Inc. (Vanguard), a family of over 200 funds. All of the funds that are members of Vanguard (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

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

How Is Vanguard’s Corporate Structure Unique?

Vanguard is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that are owned by third parties—either public or private stockholders—and not by the funds they serve.

Investment Advisor

The Vanguard Group, Inc., P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Equity Index Group. As of XX XX, 20XX, Vanguard served as advisor for approximately $xx trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds’ Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.

Although the Fund is managed solely by Vanguard, the Fund reserves the right to utilize a multimanager approach in the future. Under the terms of an SEC exemption, the Board may, without prior approval from shareholders, change the terms of an advisory agreement with a third-party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund’s advisory arrangement will be communicated to shareholders in writing. As the Fund’s sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the Board that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking an SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.

For a discussion of why the Board approved the Fund’s investment advisory arrangement, see the Financial Statements and Other Information following the commencement of operations.

The managers primarily responsible for the day-to-day management of the Fund are:

John Kraynak, CFA, Portfolio Manager at Vanguard. He has been with Vanguard since 2010, has worked in investment management since 2018, and has co-managed the Fund since its inception in xx 202x. Education: B.S., Millersville University; M.B.A., Drexel University.

Christine D. Franquin, Principal of Vanguard. She has managed investment portfolios since joining Vanguard in 2000 and has co-managed the Fund since its

inception in XX 20XX. Education: B.A., Universitaire Faculteiten Sint-Ignatius Antwerpen, Belgium; J.D., University of Liege, Belgium; M.S., Clark University.

Jeffrey D. Miller, Portfolio Manager at Vanguard. He has been with Vanguard since 1999, has managed investment portfolios since 2010, and has co- managed the Fund since its inception in XX 20XX. Education: B.A., The Pennsylvania State University; M.B.A., Drexel University.

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

Investing in Vanguard ETF® Shares

The Fund’s ETF shares are listed for trading on XX. You can buy and sell ETF shares on the secondary market in the same way you buy and sell any other exchange-traded security—through a broker. Your broker may charge a commission to execute a transaction. Unless imposed by your broker, there is no minimum dollar amount you must invest and no minimum number of ETF shares you must buy.

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 ensuring that you receive income and capital gains distributions, as well as 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.

Redemption of ETF shares by Authorized Participants

Unlike conventional (i.e., not exchange-traded) mutual fund shares, ETF shares cannot be purchased directly from or redeemed directly with the issuing fund by an individual investor. Instead, only Authorized Participants can purchase and redeem ETF shares directly from the issuing fund. Authorized Participants may purchase and redeem ETF shares from the issuing fund only in large blocks (creation units), usually in exchange for baskets of securities. Funds may also issue and redeem creation units in exchange for solely cash or a combination of cash and securities. These trades may occur in-kind between Vanguard and the Authorized Participant. If cash is used to meet redemptions, the Fund typically obtains such cash through positive cash flows or the sale of Fund holdings consistent with the Fund’s investment objective and strategy.

Under certain circumstances, including under stressed market conditions, a Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility; through

a bank line-of-credit, including a joint committed credit facility; or through an uncommitted line-of-credit from Vanguard in order to meet redemption requests.

Pricing of Fund Shares

ETF shares may only be bought and sold in the secondary market. The price you pay or receive for the ETF shares will be the prevailing market price, which may be more or less than the Fund’s NAV. Your transaction will be priced at the NAV only if you purchase or redeem your ETF shares in creation unit blocks (an option available only to certain authorized broker-dealers). NAV is typically calculated as of the close of regular trading on the New York Stock Exchange (“NYSE”), generally 4 p.m., Eastern time, on each day that the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, NAVs will be calculated as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard’s discretion), generally 4 p.m., Eastern time. The time selected for NAV calculation in this rare event generally shall also serve as the conclusion of the trading day. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Vanguard funds do not sell or redeem shares. However, on those days the value of a fund’s assets may be affected to the extent that the securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

If a fund only has one share class, the NAV per share is computed by dividing the total assets, minus liabilities, of a fund by the number of fund shares outstanding. If a fund has more than one share class, each share class has its own NAV, which is computed by dividing the total assets, minus liabilities, allocated to the share class by the number of fund shares outstanding for that class. The value of securities and other investments held by the Vanguard funds is determined pursuant to the valuation policies and procedures adopted by the Vanguard funds’ board of trustees. Vanguard has been designated as the valuation designee for the Vanguard funds pursuant to Rule 2a-5 under the Investment Company Act of 1940, subject to oversight by the Vanguard funds’ board of trustees.

Securities for which market quotations are readily available are valued at their market value, based on quotations provided by independent third-party pricing sources. Such securities are generally valued at their official closing price, the last reported sales price, or if there were no sales that day, the mean between the closing bid and asking prices, from the principal exchange or market on which they are traded. A fund’s investments in any mutual fund shares, including institutional money market fund shares, are valued at the NAVs of the mutual fund shares. A fund’s investments in any ETF shares or closed-end fund shares are valued at the market value of those shares.

When the market quotations are not readily available or do not accurately reflect the value of a security or other investment, such security or other investment is

priced at fair value, generally based on information provided by independent third-party pricing services, in accordance with the valuation policies and procedures adopted by the Vanguard funds’ board of trustees. Fair value represents a good faith determination of the value of a fund’s investments. The fair value of a security or other investment is the amount that the owner might reasonably expect to receive upon the current sale of the security or other investment. Fair-value pricing may require subjective determinations. It is possible that the price determined through fair-value pricing may differ from the price quoted or published by other sources and may not be the price at which those investments could have been sold during the period in which the fair value was used.

Fair-value pricing may be used in a variety of circumstances. For example, it may be used if the value of a security or other investment has been materially affected by events occurring after the close of the principal exchange or market on which the security is traded but before the funds’ NAV is calculated. These events might be company-specific (e.g., earnings report, merger announcement), country-specific (e.g., significant price movements in U.S. or a foreign market), or regional/global events (e.g., natural disaster, economic or political news, interest rate change, act of terrorism). These events could affect a single security or a large number of securities in a particular market, and it most commonly occurs with foreign portfolio holdings because many foreign markets operate at times that do not coincide with those of the major U.S. markets. Events that could affect the value of the foreign portfolio holdings may occur between the close of the foreign market and the time a fund’s NAV is calculated. The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of regular trading on the NYSE.

In addition, fair-value pricing may be used if trading in a security is halted and does not resume before a fund’s pricing time, a security does not trade in the course of a day and a fund holds enough of the security that its price could affect the NAV, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available.

Fixed income securities are generally valued based on information furnished by independent pricing services and are priced at fair value. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed income securities assuming orderly transactions of an institutional round lot size, but a fund may hold or transact in such securities in smaller odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

Failures by third-party pricing services to carry out their obligations to the Vanguard funds (e.g., any errors in the data provided by third-party pricing services) could result in delays in the calculation of the funds’ NAVs and/or the inability to calculate the NAVs over extended time periods. The funds may be unable to recover any losses associated with such failures.

The Vanguard funds have authorized certain financial intermediaries and their designees, and may, from time to time, authorize certain funds of funds for which Vanguard serves as the investment advisor (Vanguard Funds of Funds), to accept orders to purchase or redeem fund shares on behalf of the Vanguard funds. In these circumstances, the Vanguard fund will be deemed to receive an order when accepted by the authorized financial intermediary, its designee, or one of the Vanguard Funds of Funds, and the order will be executed using the NAV next calculated after such acceptance.

Vanguard’s website will show the previous day’s closing NAV and closing market price for the fund’s ETF shares. The website also discloses, in the Premium/Discount analysis section of a fund’s Price and Performance page, how frequently the fund traded at a premium or discount to NAV (based on closing NAVs and market prices) and the magnitudes of such premiums and discounts.

Dividends, Distributions, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest less expenses) as well as any net short-term or long-term capital gains realized from the sale of its holdings. The Fund may also make distributions that are treated as a return of capital. Income dividends generally are distributed quarterly in March, June, September, and December; capital gains distributions, if any, generally occur annually in December. In addition, the Fund may make a supplemental distribution at some other time during the year.

From time to time, Vanguard and/or a fund's board of trustees may adjust a fund's fees and expenses and/or reduce, refund, reimburse, waive, or otherwise return to the funds and their shareholders a portion of prior fees and expenses (collectively, "expense adjustments"). Fund performance and potentially shareholder distributions, will reflect such expense adjustments. If you sell all or part of your investment in a fund before an expense adjustment occurs, then you will not receive the economic benefit, if any, of such expense adjustment. An expense adjustment at any given time does not imply or guarantee that similar or additional expense adjustments will be made in the future.

Reinvestment of Distributions

In order to reinvest dividend and capital gains distributions, investors in the Fund’s ETF shares must hold their shares at a broker that offers a reinvestment

service. This can be the broker’s own service or a service made available by a third party, such as the broker’s outside clearing firm or the Depository Trust Company (DTC). If a reinvestment service is available, distributions of income and capital gains can automatically be reinvested in additional whole and fractional ETF shares of the Fund. If a reinvestment service is not available, investors will receive their distributions in cash. To determine whether a reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker.

As with all exchange-traded funds, reinvestment of dividend and capital gains distributions in additional ETF shares will occur two business days or more after the ex-dividend date (the date when a distribution of dividends or capital gains is deducted from the price of the Fund’s shares). The exact number of days depends on your broker. During that time, the amount of your distribution will not be invested in the Fund and therefore will not share in the Fund’s income, gains, and losses.

Basic Tax Points

Investors in taxable accounts should be aware of the following basic federal income tax points:

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

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

•Any income dividend distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income.

•Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund.

•Income and capital gains distributions may vary considerably from month to month or year to year, as applicable, as a result of the Fund’s normal investment activities and cash flows.

•Capital gains distributions may occur if Vanguard, the Fund, or its advisor makes changes that would impact the Fund directly or indirectly, including changes to the Fund’s portfolio or advisors or changes to any other Vanguard fund or product that would involve the redemption of shares of the Fund and the related sale of the Fund’s investments. Such changes could, depending on the timing, result in capital gains distributions in the current fiscal year, subsequent fiscal year, or both.

•Your cost basis in the Fund will be decreased by the amount of any return of

capital that you receive. This, in turn, will affect the amount of any capital gain or loss that you realize when selling your shares in the Fund.

•Return of capital distributions generally are not taxable to you until your cost basis has been reduced to zero. If your cost basis is at zero, return of capital distributions will be treated as capital gains.

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

•If you purchase shares before an ex-dividend date when a fund has realized but not yet distributed income or capital gains, the purchase price may include the amount of the upcoming distribution, and you may pay the full price for the shares and later receive a portion of the purchase price back as a taxable distribution. In such case, you generally will be taxed upon receipt of such distribution, even though the distribution effectively represents a return of a portion of your purchase price. This is known as “buying a dividend.”

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

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

The Fund may be subject to foreign taxes or foreign tax withholding on dividends, interest, and capital gains from foreign securities. If, at the end of the taxable year, more than 50% of the value of the Fund’s assets consists of securities of foreign corporations, and the Fund makes a special election, you will generally be required to include in your income, for U.S. federal income tax purposes, your share of the qualifying foreign income taxes paid by the Fund in respect of its foreign portfolio securities. There is no assurance that the Fund will make this election for a taxable year, even if it is eligible to do so. You may qualify for an offsetting credit or deduction under U.S. tax laws for any amount designated as your portion of the Fund’s foreign tax obligations, provided that you meet certain requirements. See your tax advisor or IRS publications for more information.

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

Frequent Trading Limitations

Unlike frequent trading of a Vanguard fund’s conventional share classes, frequent trading of ETF shares generally does not disrupt portfolio management or otherwise harm fund shareholders. The vast majority of trading in ETF shares occurs on the secondary market. Because these trades do not involve the issuing fund, they do not pose potential harm to the fund or its shareholders. Certain broker-dealers are authorized to purchase and redeem ETF shares directly with the issuing fund. Because these trades typically are effected in kind (i.e., for securities and not for cash), or are assessed a transaction fee when

effected in cash, they do not cause any of the harmful effects to the issuing fund (as previously noted) that may result from frequent trading. For these reasons, the Board of each Fund that issues ETF shares has determined that it is not necessary to adopt policies and procedures to detect and deter frequent trading and market-timing of ETF shares.

Additional Information

A precautionary note to investment companies. The Fund’s shares are issued by a registered investment company, and therefore the acquisition of such shares by other investment companies and private funds is subject to the restrictions of Section 12(d)(1) of the Investment Company Act of 1940 (the 1940 Act). SEC Rule 12d1-4 under the 1940 Act permits registered investment companies to invest in other registered investment companies beyond the limits in Section 12(d)(1), subject to certain conditions, including that funds with different investment advisors must enter into a fund of funds

investment agreement.

Forum selection. The Trust’s Bylaws designate Delaware courts as the exclusive forum for certain claims against or related to the Trust, a trustee, an officer, or other employee of the Trust, except that, unless the Trust otherwise consents in writing, the U.S. Federal District Courts are the exclusive forum for the resolution of complaints under the Securities Act of 1933 or the 1940 Act. These provisions may limit a shareholder’s ability to bring a claim in a different forum and may result in increased shareholder costs in pursuing such a claim.

Shareholder rights. The Fund’s Agreement and Declaration of Trust, as amended, requires a shareholder bringing a derivative action on behalf of the Trust that is subject to a pre-suit demand to collectively hold at least 10% of the outstanding shares of the Trust or at least 10% of the outstanding shares of the series or class to which the demand relates and to undertake to reimburse the Trust for the expense of any counsel or advisors used when considering the merits of the demand in the event that the board of trustees determines not to bring such action. In each case, these requirements do not apply to claims arising under the federal securities laws to the extent that any such federal securities laws, rules, or regulations do not permit such application. The Trust’s Bylaws also provide that shareholders waive the right to trial by jury to the fullest extent permitted by law.

Joint committed credit facility. The Fund participates, along with other funds managed by Vanguard, in a committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each Vanguard fund is individually liable for its borrowings, if any, under the credit facility. The amount and terms of the committed credit facility are subject to approval by the Board and renegotiation with the lender syndicate on an annual basis.

Certain affiliates of the Fund and the advisor may purchase and resell ETF shares pursuant to the prospectus.

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

Organization

Vanguard World Fund was organized as Ivest Fund, a Massachusetts corporation, in 1959. It became a Maryland corporation in 1973, and was reorganized as a Delaware statutory trust in 1998. Prior to its reorganization as a Delaware statutory trust, the Trust was known as Vanguard World Fund, Inc. The Trust is registered with the United States Securities and Exchange Commission (SEC) under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. The Funds are classified as diversified within the meaning of the 1940 Act.

Service Providers

Custodians. State Street Bank and Trust Company, One Congress Street, Suite 1, Boston, MA 02114 serves as the Funds’ custodian. The custodian is responsible for maintaining the Funds’ assets, keeping all necessary accounts and records of Fund assets, and appointing any foreign subcustodians or foreign securities depositories.

Independent Registered Public Accounting Firm. xx, serves as the Funds’ independent registered public accounting firm. The independent registered public accounting firm audits the Funds’ annual financial statements and provides other related services.

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. 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 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 approved by the Fund’s board of trustees.

Voting Rights. Shareholders are entitled to vote on a matter if (1) the matter concerns an amendment to the Declaration of Trust that would adversely affect to a material degree the rights and preferences of the shares of 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 (please see Fundamental Policies), 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 the 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 by the shareholders.

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. There are no conversion rights associated with Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF.

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.

Shareholder Rights. Any limitations on a shareholder’s right to bring an action do not apply to claims arising under the federal securities laws to the extent that any such federal securities laws, rules, or regulations do not permit such limitations. The Trust’s bylaws place limitations on the forum in which certain claims against or related to the Trust, a trustee, an officer, or other employee of the Trust may be heard. The Trust’s bylaws also provide that shareholders waive the right to trial by jury to the fullest extent permitted by law.

Tax Status of the Funds

Each Fund expects to qualify each year for treatment as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the IRC). This special tax status means that the Fund will not be liable for federal tax on income and capital gains distributed to shareholders. In order to preserve its tax status, each Fund must comply with certain requirements relating to the source of its income and the diversification of its assets. If a Fund fails to meet these requirements in any taxable year, the Fund will, in some cases, be able to cure such failure, including by paying a fund-level tax, paying interest, making additional distributions, and/or disposing of certain assets. If the Fund is ineligible to or otherwise does not cure such failure for any year, it will be subject to tax on its taxable income at

corporate rates, and all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, will be taxable to shareholders as ordinary income. In addition, 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 (excluding Real Estate Investment Trusts (REITs)) and certain foreign corporations generally may be eligible to be reported by the Fund, and treated by individual shareholders, as “qualified dividend income” taxed at long-term capital gain rates instead of at higher ordinary income tax rates. Individuals must satisfy holding period and other requirements in order to be eligible for such treatment. Also, distributions attributable to income earned on a Fund’s securities lending transactions, including substitute dividend payments received by a Fund with respect to a security out on loan, will not be eligible for treatment as qualified dividend income.

Taxable ordinary dividends received and distributed by each Fund on its REIT holdings may be eligible to be reported by a Fund, and treated by individual shareholders, as “qualified REIT dividends” that are eligible for a 20% deduction on its federal income tax returns. Individuals must satisfy holding period and other requirements in order to be eligible for this deduction. Shareholders should consult their own tax professionals concerning their eligibility for this deduction.

Dividends received and distributed by each Fund on shares of stock of domestic corporations (excluding REITs) may be eligible for the dividends-received deduction applicable to corporate shareholders. Corporations must satisfy certain requirements in order to claim the deduction. Also, distributions attributable to income earned on a Fund’s securities lending transactions, including substitute dividend payments received by a Fund with respect to a security out on loan, will not be eligible for the dividends-received deduction.

Each Fund may declare a capital gain dividend consisting of the excess (if any) of net realized long-term capital gains over net realized short-term capital losses. Net capital gains for a fiscal year are computed by taking into account any capital loss carryforwards of the Fund. Capital losses may be carried forward indefinitely and retain their character as either short-term or long-term.

FUNDAMENTAL POLICIES

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

Borrowing. 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.

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

Industry Concentration. Each Fund will not concentrate its investments in the securities of issuers whose principal business activities are in the same industry or group of industries, 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 a 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 (the 1933 Act), in connection with the purchase and sale of portfolio securities.

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

Some of the investment strategies and policies described on the following pages 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 by the Fund. Subsequent changes in values, net assets, or other circumstances will not be considered when determining whether the investment complies with the Fund’s investment strategies and policies.

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

Asset-Backed Securities. Asset-backed securities represent a participation in, or are secured by and payable from, pools of underlying assets such as debt securities, bank loans, motor vehicle installment sales contracts, installment loan contracts, leases of various types of real and personal property, receivables from revolving credit (i.e., credit card) agreements, and other categories of receivables. These underlying assets are securitized through the use of trusts and special purpose entities. Payment of interest and repayment of principal on asset-backed securities may be largely dependent upon the cash flows generated by the underlying assets backing the securities and, in certain cases, may be supported by letters of credit, surety bonds, or other credit enhancements. The rate of principal payments on

asset-backed securities is related to the rate of principal payments, including prepayments, on the underlying assets. The credit quality of asset-backed securities depends primarily on the quality of the underlying assets, the level of credit support, if any, provided for the securities, and the credit quality of the credit-support provider, if any. The value of asset-backed securities may be affected by the various factors described above and other factors, such as changes in interest rates, the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the underlying assets, or the entities providing the credit enhancement.

Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate, as a result of the pass-through of prepayments of principal on the underlying assets. Prepayments of principal by borrowers or foreclosure or other enforcement action by creditors shortens the term of the underlying assets. The occurrence of prepayments is a function of several factors, such as the level of interest rates, the general economic conditions, the location and age of the underlying obligations, and other social and demographic conditions. A fund’s ability to maintain positions in asset-backed securities is affected by the reductions in the principal amount of the underlying assets because of prepayments. A fund’s ability to reinvest such prepayments of principal (as well as interest and other distributions and sale proceeds) at a comparable yield is subject to generally prevailing interest rates at that time. The value of asset-backed securities varies with changes in market interest rates generally and the differentials in yields among various kinds of U.S. government securities, mortgage-backed securities, and asset-backed securities. In periods of rising interest rates, the rate of prepayment tends to decrease, thereby lengthening the average life of the underlying securities. Conversely, in periods of falling interest rates, the rate of prepayment tends to increase, thereby shortening the average life of such assets. Because prepayments of principal generally occur when interest rates are declining, an investor, such as a fund, generally has to reinvest the proceeds of such prepayments at lower interest rates than those at which the assets were previously invested. Therefore, asset-backed securities have less potential for capital appreciation in periods of falling interest rates than other income-bearing securities of comparable maturity.

Because asset-backed securities generally do not have the benefit of a security interest in the underlying assets that is comparable to a mortgage, asset-backed securities present certain additional risks that are not present with mortgage-backed securities. For example, revolving credit receivables are generally unsecured and the debtors on such receivables are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the right to set off certain amounts owed, thereby reducing the balance due. Automobile receivables generally are secured, but by automobiles rather than by real property. Most issuers of automobile receivables permit loan servicers to retain possession of the underlying assets. If the servicer of a pool of underlying assets sells them to another party, there is the risk that the purchaser could acquire an interest superior to that of holders of the asset-backed securities. In addition, because of the large number of vehicles involved in a typical issue of asset-backed securities and technical requirements under state law, the trustee for the holders of the automobile receivables may not have a proper security interest in the automobiles. Therefore, there is the possibility that recoveries on repossessed collateral may not be available to support payments on these securities. Asset-backed securities have been, and may continue to be, subject to greater liquidity risks when worldwide economic and liquidity conditions deteriorate. In addition, government actions and proposals that affect the terms of underlying home and consumer loans, thereby changing demand for products financed by those loans, as well as the inability of borrowers to refinance existing loans, have had and may continue to have a negative effect on the valuation and liquidity of asset-backed securities.

Bank Loans, Loan Interests, and Direct Debt Instruments. Loan interests and direct debt instruments are interests in amounts owed by a corporate, governmental, or other borrower to lenders or lending syndicates (in the case of loans and loan participations); to suppliers of goods or services (in the case of trade claims or other receivables); or to other parties. These investments involve a risk of loss in case of default, insolvency, or the bankruptcy of the borrower; may not be deemed to be securities under certain federal securities laws; and may offer less legal protection to the purchaser in the event of fraud or misrepresentation, or there may be a requirement that a purchaser supply additional cash to a borrower on demand.

Purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of interest and repayment of principal. Direct debt instruments may not be rated by a rating agency. If scheduled interest or principal payments are not made, or are not made in a timely manner, the value of the instrument may be adversely affected. Loans that are fully secured provide more protections than unsecured loans in the event of failure to make scheduled interest or principal payments. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the borrower’s obligation or that the collateral could be liquidated. Indebtedness of borrowers whose creditworthiness is poor involves substantially greater risks and may be highly speculative. Borrowers

that are in bankruptcy or restructuring may never pay off their indebtedness, or they may pay only a small fraction of the amount owed. Direct indebtedness of countries, particularly developing countries, also involves a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

Corporate loans and other forms of direct corporate indebtedness in which a fund may invest generally are made to finance internal growth, mergers, acquisitions, stock repurchases, refinancing of existing debt, leveraged buyouts, and other corporate activities. A significant portion of the corporate indebtedness purchased by a fund may represent interests in loans or debt made to finance highly leveraged corporate acquisitions (known as “leveraged buyout” transactions), leveraged recapitalization loans, and other types of acquisition financing. Another portion may also represent loans incurred in restructuring or “work-out” scenarios, including super-priority debtor-in-possession facilities in bankruptcy and acquisition of assets out of bankruptcy. Loans in restructuring or work-out scenarios may be especially vulnerable to the inherent uncertainties in restructuring processes. In addition, the highly leveraged capital structure of the borrowers in any such transactions, whether in acquisition financing or restructuring, may make such loans especially vulnerable to adverse or unusual economic or market conditions.

Loans and other forms of direct indebtedness generally are subject to restrictions on transfer, and only limited opportunities may exist to sell them in secondary markets. As a result, a fund may be unable to sell loans and other forms of direct indebtedness at a time when it may otherwise be desirable to do so or may be able to sell them only at a price that is less than their fair value.

Investments in loans through direct assignment of a financial institution’s interests with respect to a loan may involve additional risks. For example, if a loan is foreclosed, the purchaser could become part owner of any collateral and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is at least conceivable that, under emerging legal theories of lender liability, a purchaser could be held liable as a co-lender. Direct debt instruments may also involve a risk of insolvency of the lending bank or other intermediary.

A loan is often administered by a bank or other financial institution that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. Unless the purchaser has direct recourse against the borrower, the purchaser may have to rely on the agent to apply appropriate credit remedies against a borrower under the terms of the loan or other indebtedness. If assets held by the agent for the benefit of a purchaser were determined to be subject to the claims of the agent’s general creditors, the purchaser might incur certain costs and delays in realizing payment on the loan or loan participation and could suffer a loss of principal and/or interest.

Direct indebtedness may include letters of credit, revolving credit facilities, or other standby financing commitments that obligate purchasers to make additional cash payments on demand. These commitments may have the effect of requiring a purchaser to increase its investment in a borrower when it would not otherwise have done so, even if the borrower’s condition makes it unlikely that the amount will ever be repaid.

A fund’s investment policies will govern the amount of total assets that it may invest in any one issuer or in issuers within the same industry. For purposes of these limitations, a fund generally will treat the borrower as the “issuer” of indebtedness held by the fund. In the case of loan participations in which a bank or other lending institution serves as financial intermediary between a fund and the borrower, if the participation does not shift to the fund the direct debtor-creditor relationship with the borrower, SEC interpretations require the fund, in some circumstances, to treat both the lending bank or other lending institution and the borrower as “issuers” for purposes of the fund’s investment policies. Treating a financial intermediary as an issuer of indebtedness may restrict a fund’s ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

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 (i.e., 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 (at the time of borrowing) made for temporary or emergency purposes. Any borrowings for temporary purposes in excess of 5% of the fund’s total assets must maintain continuous asset coverage. If the 300% asset coverage should decline as a result of market fluctuations or for other reasons, a fund may be required to sell some of its portfolio holdings within three days (excluding Sundays and holidays) to reduce the debt and restore the 300% asset coverage, even though it may be disadvantageous from an investment standpoint to sell securities at that time.

Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of a fund’s portfolio. Money borrowed will be subject to interest costs that may or may not be recovered by earnings on the securities purchased with the proceeds of such borrowing. 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.

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 complies with Rule 18f-4 under the 1940 Act.

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

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

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

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

Cybersecurity Risks. A cybersecurity incident could subject the Vanguard funds, their advisors, and/or their third-party service providers to operational and financial risks. Cybersecurity incidents typically result from a deliberate attack, which could take multiple forms (e.g., phishing, malware, ransomware, or denial-of-service attacks), or wrongdoing by an authorized individual. In either case, sensitive assets, information, or data could fall into the hands of unauthorized

individuals and potentially cause operational disruption. To prevent or reduce the impact of a cybersecurity incident, Vanguard has implemented controls, such as technological safeguards and business continuity plans. Cybersecurity risks are also present for third-party service providers (such as investment advisors, transfer agents, and custodians) that support the Vanguard funds. Vanguard has processes for assessing the cybersecurity programs implemented by a fund’s third-party service providers. These processes help reduce the risk of potential incidents that could impact a Vanguard fund and/or its shareholders.

Despite the measures described above, a cybersecurity incident could still disrupt business operations, which could affect a fund and/or its shareholders. Examples of impacts that might occur as a result of a cybersecurity incident include: a fund being unable to calculate its net asset value (NAV) or process transactions, fund shareholders being unable to place transactions or otherwise conduct business with Vanguard, or a fund being unable to safeguard its data or the personal information of its shareholders.

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

Debt Securities—Bank Obligations. Time deposits are non-negotiable deposits maintained in a banking institution for a specified period of time at a stated interest rate. Certificates of deposit are negotiable short-term obligations of commercial banks. Variable rate certificates of deposit have an interest rate that is periodically adjusted prior to their stated maturity based upon a specified market rate. As a result of these adjustments, the interest rate on these obligations may be increased or decreased periodically. Frequently, dealers selling variable rate certificates of deposit to a fund will agree to repurchase such instruments, at the fund’s option, at par on or near the coupon dates. The dealers’ obligations to repurchase these instruments are subject to conditions imposed by various dealers; such conditions typically are the continued credit standing of the issuer and the existence of reasonably orderly market conditions. A fund is also able to sell variable rate certificates of deposit on the secondary market. Variable rate certificates of deposit normally carry a higher interest rate than comparable fixed-rate certificates of deposit. A banker’s acceptance is a time draft drawn on a commercial bank by a borrower usually in connection with an international commercial transaction (to finance the import, export, transfer, or storage of goods). The borrower is liable for payment, as is the bank, which unconditionally guarantees to pay the draft at its face amount on the maturity date. Most acceptances have maturities of 6 months or less and are traded in the secondary markets prior to maturity.

Debt Securities—Commercial Paper. Commercial paper refers to short-term, unsecured promissory notes issued by corporations to finance short-term credit needs. It is usually sold on a discount basis and has a maturity at the time of issuance not exceeding 9 months. High-quality commercial paper typically has the following characteristics: (1) liquidity ratios are adequate to meet cash requirements; (2) long-term senior debt is also high credit quality; (3) the issuer has access to at least two additional channels of borrowing; (4) basic earnings and cash flow have an upward trend with allowance made for unusual circumstances; (5) typically, the issuer’s industry is well established and the issuer has a strong position within the industry; and (6) the reliability and quality of management are unquestioned. In assessing the credit quality of commercial paper issuers, the following factors may be considered: (1) evaluation of the management of the issuer, (2) economic evaluation of the issuer’s industry or industries and the appraisal of speculative-type risks that may be inherent in certain areas, (3) evaluation of the issuer’s products in relation to competition and customer acceptance, (4) liquidity, (5) amount and quality of long-term debt, (6) trend of earnings over a period of ten years, (7) financial strength of a parent company and the relationships that exist with the issuer, and (8) recognition by the management of obligations that may be present or may arise as a result of public-interest questions and preparations to meet such obligations. The short-term nature of a commercial paper investment makes it less susceptible to interest rate risk than longer-term fixed income securities because interest rate risk typically increases as maturity lengths increase. Additionally, an issuer may expect to repay commercial paper obligations at maturity from the proceeds of the

issuance of new commercial paper. As a result, investment in commercial paper is subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper payment obligations, also known as rollover risk. Commercial paper may suffer from reduced liquidity due to certain circumstances, in particular, during stressed markets. In addition, as with all fixed income securities, an issuer may default on its commercial paper obligation.

Variable-amount master-demand notes are demand obligations that permit the investment of fluctuating amounts at varying market rates of interest pursuant to an arrangement between the issuer and a commercial bank acting as agent for the payees of such notes, whereby both parties have the right to vary the amount of the outstanding indebtedness on the notes. Because variable-amount master-demand notes are direct lending arrangements between a lender and a borrower, it is not generally contemplated that such instruments will be traded, and there is no secondary market for these notes, although they are redeemable (and thus immediately repayable by the borrower) at face value, plus accrued interest, at any time. In connection with a fund’s investment in variable-amount master-demand notes, Vanguard’s investment management staff will monitor, on an ongoing basis, the earning power, cash flow, and other liquidity ratios of the issuer, along with the borrower’s ability to pay principal and interest on demand.

Debt Securities—Emerging Market Risk. Investing in emerging market countries involves certain risks not typically associated with investing in the United States, and imposes risks greater than, or in addition to, risks of investing in more developed foreign countries. These risks may significantly affect the value of emerging market investments and include, but are not limited to, the following: (i) nationalization or expropriation of assets or confiscatory taxation; (ii) currency devaluations and other currency exchange rate fluctuations; (iii) greater social, economic, and political uncertainty and instability (including amplified risk of war and terrorism); (iv) more substantial government involvement in and control over the economy; (v) less government supervision and regulation of the securities markets and participants in those markets and possible arbitrary and unpredictable enforcement of securities regulations and other laws, which may increase the risk of market manipulation; (vi) controls on foreign investment and limitations on repatriation of invested capital and on a fund’s ability to exchange local currencies for U.S. dollars; (vii) unavailability of currency hedging techniques in certain emerging market countries; (viii); generally, smaller, less seasoned, or newly organized companies; (ix) the difference in, or lack of, corporate governance, accounting, auditing, recordkeeping, and financial reporting standards, which may result in unavailability of material information about issuers and impede evaluation of such issuers; (x) difficulty in obtaining and/or enforcing a judgment in a court outside the United States; and (xi) greater price volatility, substantially less liquidity, and significantly smaller market capitalization of bond markets. Also, any change in the leadership or politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities. Furthermore, high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and bond markets of certain emerging market countries. Custodial expenses and other investment-related costs are often more expensive in emerging market countries, which can reduce a fund’s income from investments in securities or debt instruments of emerging market country issuers. Additionally, information regarding companies located in emerging markets may be less available and less reliable, which can impede the ability to evaluate such companies. There may also be limited regulatory oversight of certain foreign subcustodians that hold foreign securities subject to the supervision of a fund’s primary U.S.-based custodian. A fund may be limited in its ability to recover assets if a foreign subcustodian becomes bankrupt or otherwise unable or unwilling to return assets to the fund, which may expose the fund to risk, especially in circumstances where the fund’s primary custodian may not be contractually obligated to make the fund whole for the particular loss.

Emerging market investments also carry the risk that strained international relations may give rise to retaliatory actions, including actions through financial markets such as purchase and ownership restrictions, sanctions, tariffs, seizure of assets, cyberattacks, and unpredictable enforcement of securities regulations and other laws. Such actual and/or threatened retaliatory actions may impact emerging market economies and issuers in which a fund invests. For example, in China, ownership of companies in certain sectors by foreign individuals and entities is prohibited.

Debt Securities—Foreign Securities. Typically, foreign debt securities are issued by entities organized, domiciled, or with a principal executive office outside the United States, such as foreign corporations and governments. Foreign debt securities may trade in U.S. or foreign securities markets. Investing in foreign debt securities involves certain special risk considerations that are not typically associated with investing in debt securities of U.S. companies or governments.

Because foreign issuers are not generally subject to uniform accounting, auditing, and financial reporting standards and practices comparable to those applicable to U.S. issuers, there may be less publicly available information about certain foreign issuers than about U.S. issuers. Evidence of securities ownership may be uncertain in many foreign countries.

As a result, there are risks that could result in a loss to the fund, including, but not limited to, the risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of the transaction. Securities of foreign issuers are generally more volatile and less liquid than securities of comparable U.S. issuers, and foreign investments may be effected through structures that may be complex or confusing. In certain countries, there is less government supervision and regulation of bond markets, bond dealers, and bond issuers than in the United States. In addition, with respect to certain foreign countries, there is the possibility of expropriation or taxation or other adverse tax consequences, political or social instability, changes to laws and regulations or interpretations of laws and regulations, war, terrorism, nationalization, limitations on the removal of funds or other assets, or diplomatic developments that could affect U.S. investments in those countries. Additionally, the imposition of economic or other sanctions on the United States by a foreign country, or on a foreign country or issuer by the United States, could impair a fund’s ability to buy, sell, hold, receive, deliver, or otherwise transact in certain investment securities or obtain exposure to foreign securities and assets. This may negatively impact the value and/or liquidity of a fund’s investments and could impair a fund’s ability to meet its investment objective or invest in accordance with its investment strategy. Sanctions could also result in the devaluation of a country’s currency, a downgrade in the credit ratings of a country or issuers in a country, or a decline in the value and/or liquidity of securities of issuers in that country.

Although an advisor will endeavor to achieve the most favorable execution costs for a fund’s portfolio transactions in foreign securities under the circumstances, mark-ups and other transaction costs are generally higher than those on U.S. securities. In addition, it is expected that the custodian arrangement expenses for a fund that invests primarily in foreign securities will be somewhat greater than the expenses for a fund that invests primarily in domestic securities. Certain foreign governments levy withholding or other taxes against dividend and interest income from or transactions in foreign securities. Although in some countries a portion of these taxes is recoverable by the fund, the nonrecovered portion of foreign withholding taxes will reduce the income received from such securities.

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

Debt Securities—Inflation-Indexed Securities. Inflation-indexed securities are debt securities, the principal value of which is periodically adjusted to reflect the rate of inflation as indicated by the Consumer Price Index (CPI). Inflation-indexed securities may be issued by the U.S. government, by agencies and instrumentalities of the U.S. government, and by corporations. Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the CPI accruals as part of a semiannual coupon payment.

The periodic adjustment of U.S. inflation-indexed securities is tied to the CPI, which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI is a measurement of changes in the cost of living, made up of components such as housing, food, transportation, and energy. Inflation-indexed securities issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the CPI or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will correlate to the rate of inflation in the United States.

Inflation—a general rise in prices of goods and services—erodes the purchasing power of an investor’s portfolio. For example, if an investment provides a “nominal” total return of 5% in a given year and inflation is 2% during that period, the inflation-adjusted, or real, return is 3%. Inflation, as measured by the CPI, has generally occurred during the past 50 years, so investors should be conscious of both the nominal and real returns of their investments. Investors in inflation-indexed securities funds who do not reinvest the portion of the income distribution that is attributable to inflation adjustments will not maintain the purchasing power of the investment over the long term. This is because interest earned depends on the amount of principal invested, and that principal will not grow with inflation if the investor fails to

reinvest the principal adjustment paid out as part of a fund’s income distributions. Although inflation-indexed securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise because of reasons other than inflation (e.g., changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

If the periodic adjustment rate measuring inflation (i.e., the CPI) falls, the principal value of inflation-indexed securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed securities, even during a period of deflation. However, the current market value of the inflation-indexed securities is not guaranteed and will fluctuate. Other inflation-indexed securities include inflation-related bonds, which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

The value of inflation-indexed securities should change in response to changes in real interest rates. Real interest rates, in turn, are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed securities. In contrast, if nominal interest rates were to increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed securities.

Coupon payments that a fund receives from inflation-indexed securities are included in the fund’s gross income for the period during which they accrue. Any increase in principal for an inflation-indexed security resulting from inflation adjustments is considered by Internal Revenue Service (IRS) regulations to be taxable income in the year it occurs. For direct holders of an inflation-indexed security, this means that taxes must be paid on principal adjustments, even though these amounts are not received until the bond matures. By contrast, a fund holding these securities distributes both interest income and the income attributable to principal adjustments each quarter in the form of cash or reinvested shares (which, like principal adjustments, are taxable to shareholders). It may be necessary for the fund to liquidate portfolio positions, including when it is not advantageous to do so, in order to make required distributions.

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

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

Some high-yield securities are issued by smaller, less-seasoned companies, while others are issued as part of a corporate restructuring such as an acquisition, a merger, or a leveraged buyout. Companies that issue high-yield securities are often highly leveraged and may not have more traditional methods of financing available to them.

Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with investment-grade securities. Some high-yield securities were once rated as investment-grade but have been downgraded to junk bond status because of financial difficulties experienced by their issuers.

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

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

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

Debt Securities—Structured and Indexed Securities. Structured securities (also called “structured notes”) and indexed securities are derivative debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities include structured notes as well as securities other than debt securities. The value of the principal of and/or interest on structured and indexed securities is determined by reference to changes in the value of a specific asset, reference rate, or index (the reference) or the relative change in two or more references. The interest rate or the principal amount payable upon maturity or redemption may be increased or decreased, depending upon changes in the applicable reference. The terms of the structured and indexed securities may provide that, in certain circumstances, no principal is due at maturity and, therefore, may result in a loss of invested capital. Structured and indexed securities may be positively or negatively indexed, so that appreciation of the reference may produce an increase or a decrease in the interest rate or value of the security at maturity. In addition, changes in the interest rate or the value of the structured or indexed security at maturity may be calculated as a specified multiple of the change in the value of the reference; therefore, the value of such security may be very volatile. Structured and indexed securities may entail a greater degree of market risk than other types of debt securities because the investor bears the risk of the reference. Structured or indexed securities may also be more volatile, less liquid, and more difficult to accurately price than less complex securities or more traditional debt securities, which could lead to an overvaluation or an undervaluation of the securities.

Debt Securities—U.S. Government Securities. The term “U.S. government securities” refers to a variety of debt securities that are issued or guaranteed by the U.S. Treasury, by various agencies of the U.S. government, or by various instrumentalities that have been established or sponsored by the U.S. government. The term also refers to repurchase agreements collateralized by such securities.

U.S. Treasury securities are backed by the full faith and credit of the U.S. government, meaning that the U.S. government is required to repay the principal in the event of default. Other types of securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government. The U.S. government, however, does not guarantee the market price of any U.S. government securities. In the case of securities not backed by the full faith and credit of the U.S. government, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment and may not be able to assert a claim against the United States itself in the event the agency or instrumentality does not meet its commitment.

Some of the U.S. government agencies that issue or guarantee securities include the Government National Mortgage Association, the Export-Import Bank of the United States, the Federal Housing Administration, the Maritime Administration, the Small Business Administration, and the Tennessee Valley Authority. An instrumentality of the U.S. government is a government agency organized under federal charter with government supervision. Instrumentalities issuing or guaranteeing securities include, among others, the Federal Deposit Insurance Corporation, the Federal Home Loan Banks, and the Federal National Mortgage Association. From time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. government-sponsored entity is negatively impacted by legislative or regulatory action, is unable to meet its obligations, or its creditworthiness declines, the performance of a fund that holds securities of the entity may be adversely impacted.

Debt Securities—Variable and Floating Rate Securities. Variable and floating rate securities are debt securities that provide for periodic adjustments in the interest rate paid on the security. Variable rate securities provide for a specified periodic adjustment in the interest rate, while floating rate securities have interest rates that change whenever there is a change in a designated benchmark or reference rate (such as the Secured Overnight Financing Rate (SOFR) or another reference rate) or the issuer’s credit quality. There is a risk that the current interest rate on variable and floating rate securities may not accurately reflect current market interest rates or adequately compensate the holder for the current

creditworthiness of the issuer. Some variable or floating rate securities are structured with liquidity features such as (1) put options or tender options that permit holders (sometimes subject to conditions) to demand payment of the unpaid principal balance plus accrued interest from the issuers or certain financial intermediaries or (2) auction-rate features, remarketing provisions, or other maturity-shortening devices designed to enable the issuer to refinance or redeem outstanding debt securities (market-dependent liquidity features). Variable or floating rate securities that include market-dependent liquidity features may have greater liquidity risk than other securities. The greater liquidity risk may exist, for example, because of the failure of a market-dependent liquidity feature to operate as intended (as a result of the issuer’s declining creditworthiness, adverse market conditions, or other factors) or the inability or unwillingness of a participating broker-dealer to make a secondary market for such securities. As a result, variable or floating rate securities that include market-dependent liquidity features may lose value, and the holders of such securities may be required to retain them until the later of the repurchase date, the resale date, or the date of maturity. A demand instrument with a demand notice exceeding seven days may be considered illiquid if there is no secondary market for such security.

Debt Securities—Zero-Coupon and Pay-in-Kind Securities. Zero-coupon and pay-in-kind securities are debt securities that do not make regular cash interest payments. Zero-coupon securities generally do not pay interest. Zero-coupon Treasury bonds are U.S. Treasury notes and bonds that have been stripped of their unmatured interest coupons, or the coupons themselves, and also receipts or certificates representing an interest in such stripped debt obligations and coupons. The timely payment of coupon interest and principal on these instruments remains guaranteed by the full faith and credit of the U.S. government. Pay-in-kind securities pay interest through the issuance of additional securities. These securities are generally issued at a discount to their principal or maturity value. Because such securities do not pay current cash income, the price of these securities can be volatile when interest rates fluctuate. Although these securities do not pay current cash income, federal income tax law requires the holders of zero-coupon and pay-in-kind securities to include in income each year the portion of the original issue discount and other noncash income on such securities accrued during that year. Each fund that holds such securities intends to pass along such interest as a component of the fund’s distributions of net investment income. It may be necessary for the fund to liquidate portfolio positions, including when it is not advantageous to do so, in order to make required distributions.

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

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

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

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

Derivatives. A derivative is a financial instrument that has a value based on—or “derived from”—the values of other assets, reference rates, or indexes. Derivatives may relate to a wide variety of underlying references, such as commodities, stocks, bonds, interest rates, currency exchange rates, and related indexes. Derivatives include futures contracts and options on futures contracts, certain forward-commitment transactions, options on securities, caps, floors, collars, swap agreements, and certain 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, may be privately negotiated and entered into in the over-the-counter market (OTC Derivatives) or may be cleared through a clearinghouse (Cleared Derivatives) and traded on an exchange or swap execution facility. As a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act), certain swap agreements, such as certain standardized credit default and interest rate swap agreements, must be cleared through a clearinghouse and traded on an exchange or swap execution facility. This could result in an increase in the overall costs of such transactions. While the intent of derivatives regulatory reform is to mitigate risks associated with derivatives markets, the regulations could, among other things, increase liquidity and decrease pricing for more standardized products while decreasing liquidity and increasing pricing for less standardized products. The risks associated with the use of derivatives are different from, and possibly greater than, the risks associated with investing directly in the securities or assets on which the derivatives are based.

Derivatives may be used for a variety of purposes, including—but not limited to—hedging, managing risk, seeking to stay fully invested, seeking to reduce transaction costs, seeking to simulate an investment in equity or debt securities or other investments, and seeking to add value by using derivatives to more efficiently implement portfolio positions when derivatives are favorably priced relative to equity or debt securities or other investments. A fund may use derivatives as an alternate means to obtain economic exposure if the fund is required to limit its investment in a particular issuer or industry. Some investors may use derivatives primarily for speculative purposes while other uses of derivatives may not constitute speculation. There is no assurance that any derivatives strategy used by a fund’s advisor will succeed. The other parties to a fund’s OTC Derivatives contracts (usually referred to as “counterparties”) will not be considered the issuers thereof for purposes of certain provisions of the 1940 Act and the IRC, although such OTC Derivatives may qualify as securities or investments under such laws. A fund’s advisor(s), however, will monitor and adjust, as appropriate, the fund’s credit risk exposure to OTC 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.

When a fund enters into a Cleared Derivative, an initial margin deposit with a Futures Commission Merchant (FCM) is required. Initial margin deposits are typically calculated as an amount equal to the volatility in market value of a Cleared Derivative over a fixed period. If the value of the fund’s Cleared Derivatives declines, the fund will be required to make additional “variation margin” payments to the FCM to settle the change in value. If the value of the fund’s Cleared Derivatives increases, the FCM will be required to make additional “variation margin” payments to the fund to settle the change in value. This process is known as “marking-to-market” and is calculated on a daily basis.

For OTC Derivatives, a fund is subject to 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 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 certain 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 certain 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 complies with Rule 18f-4.

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.

Securities and Exchange Commission Rule 18f-A governs the use of derivatives by registered investment companies. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, treats derivatives as senior securities, and requires funds whose use of derivatives exceeds a limited specified exposure amount to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.

Each Fund intends to comply with Rule 4.5 under the Commodity Exchange Act (CEA), under which a fund and Vanguard may be excluded from the definition of the term Commodity Pool Operator (CPO) if the fund meets certain conditions such as limiting its investments in certain CEA-regulated instruments (e.g., futures, options, or swaps) and complying with certain marketing restrictions. Accordingly, Vanguard is not subject to registration or regulation as a CPO with respect to each Fund under the CEA. Each Fund will only enter into futures contracts and futures options that are traded on a U.S. or foreign exchange, board of trade, or similar entity or that are quoted on an automated quotation system.

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

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

Foreign Securities. Typically, foreign securities are considered to be equity or debt securities issued by entities organized, domiciled, or with a principal executive office outside the United States, such as foreign corporations and governments. Securities issued by certain companies organized outside the United States may not be deemed to be foreign securities if the company’s principal operations are conducted from the United States or when the company’s equity securities trade principally on a U.S. stock exchange. Foreign securities may trade in U.S. or foreign securities markets. A fund may make foreign investments either directly by purchasing foreign securities or indirectly by

purchasing depositary receipts or depositary shares of similar instruments (depositary receipts) for foreign securities. Direct investments in foreign securities may be made either on foreign securities exchanges or in the over-the-counter (OTC) markets. Investing in foreign securities involves certain special risk considerations that are not typically associated with investing in securities of U.S. companies or governments.

Because foreign issuers are not generally subject to uniform accounting, auditing, and financial reporting standards and practices comparable to those applicable to U.S. issuers, there may be less publicly available information about certain foreign issuers than about U.S. issuers. Evidence of securities ownership may be uncertain in many foreign countries.

As a result, there are risks that could result in a loss to the fund, including, but not limited to, the risk that a fund’s trade details could be incorrectly or fraudulently entered at the time of a transaction. Securities of foreign issuers are generally more volatile and less liquid than securities of comparable U.S. issuers, and foreign investments may be effected through structures that may be complex or confusing. In certain countries, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in the United States. The risk that securities traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by government authorities, is also heightened. 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. Additionally, the imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other government restrictions on the United States by a foreign country, or on a foreign country or issuer by the United States, could impair a fund’s ability to buy, sell, hold, receive, deliver, or otherwise transact in certain investment securities or obtain exposure to foreign securities and assets. This may negatively impact the value and/or liquidity of a fund’s investments and could impair a fund’s ability to meet its investment objective or invest in accordance with its investment strategy. Sanctions could also result in the devaluation of a country’s currency, a downgrade in the credit ratings of a country or issuers in a country, or a decline in the value and/or liquidity of securities of issuers in that country.

Although an advisor will endeavor to achieve the most favorable execution costs for a fund’s portfolio transactions in foreign securities under the circumstances, commissions and other transaction costs are generally higher than those on U.S. securities. In addition, it is expected that the custodian arrangement expenses for a fund that invests primarily in foreign securities will be somewhat greater than the expenses for a fund that invests primarily in domestic securities. Additionally, bankruptcy laws vary by jurisdiction and cash deposits may be subject to a custodian’s creditors. Certain foreign governments levy withholding or other taxes against dividend and interest income from, capital gains on the sale of, or transactions in foreign securities. Although in some countries a portion of these taxes is recoverable by the fund, the nonrecovered portion of foreign withholding taxes will reduce the income received from such securities.

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

Foreign Securities—Emerging Markets Risk. Investing in emerging market countries involves certain risks not typically associated with investing in the United States, and it imposes risks greater than, or in addition to, risks of investing in more developed foreign countries. These risks may significantly affect the value of emerging market investments and include: (i) nationalization or expropriation of assets or confiscatory taxation; (ii) currency devaluations and other currency exchange rate fluctuations; (iii) greater social, economic, and political uncertainty and instability (including amplified risk of war and terrorism); (iv) more substantial government involvement and control over the economy; (v) less government supervision and regulation of the securities markets and participants in those markets and possible arbitrary and unpredictable enforcement of securities regulations and other laws, which may increase the risk of market manipulation; (vi) controls on foreign investment and limitations on repatriation of invested capital and on a fund’s ability to exchange local currencies for U.S. dollars; (vii) unavailability of currency-hedging techniques in certain emerging market countries; (viii) generally smaller, less seasoned, or newly-organized companies; (ix) differences in, or lack of, corporate governance, accounting, auditing, recordkeeping, and financial reporting standards, which may result in unavailability of material information about issuers and impede evaluation of such issuers; (x) difficulty in obtaining and/or enforcing a judgment in a court outside the United States; and (xi) greater price volatility, substantially less liquidity, and significantly smaller market capitalization of securities markets. Also, any change in the leadership or

politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities. Furthermore, high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Custodial expenses and other investment-related costs are often more expensive in emerging market countries, which can reduce a fund’s income from investments in securities or debt instruments of emerging market country

issuers. Additionally, information regarding companies located in emerging markets may be less available and less reliable, which can impede the ability to evaluate such companies. There may also be limited regulatory oversight of certain foreign subcustodians that hold foreign securities subject to the supervision of a fund’s primary U.S.-based custodian. A fund may be limited in its ability to recover assets if a foreign subcustodian becomes bankrupt or otherwise unable or unwilling to return assets to the fund, which may expose the fund to risk, especially in circumstances where the fund’s primary custodian may not be contractually obligated to make the fund whole for the particular loss.

Emerging market investments also carry the risk that strained international relations may give rise to retaliatory actions, including actions through financial markets such as purchase and ownership restrictions, sanctions, tariffs, seizure of assets, cyberattacks, and unpredictable enforcement of securities regulations and other laws. Such actual and/or threatened retaliatory actions may impact emerging market economies and issuers in which a fund invests. For example, in China, ownership of companies in certain sectors by foreign individuals and entities is prohibited.

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 enter into foreign currency transactions only to attempt to “hedge” the currency risk associated with investing in foreign securities. Although such transactions tend

to minimize the risk of loss that would result from a decline in the value of the hedged currency, they also may limit any potential gain that might result should the value of such currency increase.

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

Currency exchange transactions may be considered borrowings. A currency exchange transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund complies with Rule 18f-4.

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

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

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

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

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

Foreign Securities—Russian Market Risk. There are significant risks inherent in investing in Russian securities. The underdeveloped state of Russia’s banking system subjects the settlement, clearing, and registration of securities transactions to significant risks. In March of 2013, the National Settlement Depository (NSD) began acting as a central depository for the majority of Russian equity securities; however, pursuant to a Russian presidential decree, the NSD no longer serves as a system for the central handling of Russian equities. Instead, ownership records are now maintained by registrars located throughout Russia.

For Russian issuers, ownership records are maintained only by registrars who are under contract with the issuers. Russian subcustodians maintain copies of the registrar’s records (Share Extracts) on its premises. The registrars may not be independent from the issuer, are not necessarily subject to effective state supervision, and may not be licensed with any governmental entity. A fund will endeavor to ensure by itself or through a custodian or other agent that the fund’s interest continues to be appropriately recorded for Russian issuers by inspecting the share register and by obtaining extracts of share registers through regular confirmations. However, these extracts have no legal enforceability, and the possibility exists that a subsequent illegal amendment or other fraudulent act may deprive the fund of its ownership rights or may improperly dilute its interest. In addition, although applicable Russian regulations impose liability on registrars for losses resulting from their errors, a fund may find it difficult to enforce any rights it may have against the registrar or issuer of the securities in the event of loss of share registration.

Russia’s launch of a large-scale invasion of Ukraine has resulted in sanctions against Russian governmental institutions, Russian entities, and Russian individuals that may result in the devaluation of Russian currency; a downgrade in the country’s credit rating; a freeze of Russian foreign assets; a decline in the value and liquidity of Russian securities, properties, or interests; and other adverse consequences to the Russian economy and Russian assets. In addition, a fund’s ability to price, buy, sell, receive, or deliver Russian investments has been and may continue to be impaired. These sanctions, divestment of interests in or curtailment of business dealing with Russia by large corporations and U.S. states, and the resulting disruption of the Russian economy, may cause volatility in other regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, which could have a negative effect on the performance of a fund, even if the fund does not have direct exposure to securities of Russian issuers.

Foreign Securities—Special Risks of Investing in China. Investing in companies or issuers economically tied to China involves a high degree of risk and special considerations not typically associated with investing in more developed economies or markets. Such risks may include but are not limited to: Chinese Government Risk, Sanctions/Geopolitical Risk, Emerging Market Risk, Chinese Renminbi Risk, Regulatory and Legal Framework Risk, and risks with accessing and investing in their equity and bond markets.

Chinese Government Risk. In China, there are no freely elected government officials and political opposition is largely suppressed. As a result, the Chinese government has an outsized impact on the Chinese market which is uncharacteristic when compared with developed nations. For example, the Chinese government has exercised authority over publicly traded Chinese companies in the past and may continue to do so. This authority can include, but is not limited to, dictating what types of products Chinese companies should produce and to whom such products can be sold, nationalizing assets, and pursuing regulatory enforcement in an unpredictable manner. The Chinese government could use this authority for a variety of reasons including targeting Chinese companies deemed to have violated Chinese interests or trying to reduce market volatility.

The nationalist focus of the Chinese government also can lead to the government making broad policy changes that deviate from what they have historically supported. The Chinese government has implemented several economic reforms since 1978. It is possible that these reforms may not be supported in the future and the government could return to a more centrally planned economy. Additional support to surrounding economies such as Hong Kong could be revoked, and foreign investment in China could be limited if not banned outright.

Sanctions/Geopolitical Risk. Investing in companies economically tied to China is subject to certain political risks. Following the establishment of the People’s Republic of China (PRC) by the Communist Party in 1949, the Chinese government renounced various debt obligations incurred by China’s predecessor governments, which obligations remain in default, and seized assets without compensation. There can be no assurance that the Chinese government will not take similar action in the future, resulting in a full or partial loss of Chinese holdings.

China has many ongoing disputes with Hong Kong, Taiwan, the Xinjiang region and the Uyghur population, and other neighboring areas. These disputes continue to escalate due to ongoing Chinese military exercises (such as land reclamation efforts in the South China Sea), Chinese policymaking, human rights violations assertions by the UN and other developed nations, and statements from high-ranking Chinese government officials. In addition, the Chinese government has been accused of participating in state-sponsored cyberattacks against other foreign countries and foreign companies.

The resulting political tensions, including with the United States, have had and may continue to have impacts on the Chinese economy and its ability to sell certain goods. Other countries, including the U.S., have imposed and may continue to impose sanctions, tariffs, and embargoes or blocking of certain goods produced in China to affect the Chinese economy. Countries have also raised concerns about Chinese companies’ compliance with their own laws which could result in the delisting of securities. Compliance with sanctions could lead to a large market selloff, which could result in significant losses to investments. While tariffs and embargoes are not direct sanctions, they can still negatively affect the Chinese economy and individual Chinese companies. Lastly, because of the economic and financial market dependence between China and the surrounding regions, any decrease in demand for goods from China or an economic downturn in China, could negatively affect the economies and financial markets of the surrounding regions.

Emerging Market Risk. China’s economy is classified as an emerging market. However, China’s economy is considered to be more reliant on exports than other emerging markets and therefore could be negatively affected by a downturn in its export business. Chinese exports could be negatively affected by the aforementioned sanctions and geopolitical risk or other restrictions such as trade tariffs, embargoes, or capital controls. Chinese exports could also be affected by increasing competition across Asia’s other emerging economies, higher rates of inflation, and/or the erratic nature of economic growth in China.

Regulatory and Legal Framework Risk. China’s ability to develop and sustain its legal, tax, regulatory, financial reporting, accounting, and recordkeeping systems could influence the course of foreign investment. Chinese companies are not subject to the same degree of regulation as those in the United States with respect to matters such as tender offer regulation, stockholder proxy requirements, and the requirements mandating timely and accurate disclosure of information. China lacks accounting, auditing, and financial reporting standards, and U.S. public accounting oversight boards are unable to inspect audit work papers and practices of registered accounting firms in China. Further complicating matters, some of China’s laws prohibit certain key information about their companies from being disclosed. As a result, obtaining the full financial picture of a publicly traded Chinese company may be more difficult than obtaining the full financial picture of a publicly traded U.S. company, making it harder to determine the true health of a company.

China’s legal framework may make it more difficult, if not impossible, to obtain or enforce a judgment compared to other countries. The Chinese regulatory framework is also less extensive and still developing regarding business entities and commercial transactions, which can make it challenging to navigate China’s markets. Chinese securities may be taxed differently than U.S. securities depending on the type of investment and the issuer.

Accessing and Investing in the Chinese Equity Market. China’s investment and banking systems are still developing, which subjects the settlement, clearing, and registration of securities transactions to additional risks and costs. Chinese companies can list their shares in a variety of ways, such as A shares, B shares, or H shares. These shares are traded on various exchanges, such as the Shanghai or Shenzhen exchange.

A-shares are generally bought through the Qualified Foreign Investor (QFI) program or Stock Connect. Trading through a license granted under the QFI regime is subject to policies and rules that are unique and evolving. In addition, QFI licenses can be revoked or restricted, preventing a fund from any future trading through the QFI regime. There are QFI custodial arrangements that can limit a fund’s ability to recover deposited cash if the QFI custodian becomes insolvent. Chinese regulators may impose fines or pursue other negative actions towards a QFI custodian if that custodian does not perform its required reporting obligations. Trades do not cross between the Shanghai and Shenzhen stock exchanges and a separate broker is assigned for each exchange. As a result, trades must be placed with separate brokers for different transaction sides, increasing complexity, potential for error, and costs.

Trading on Stock Connect is also subject to limitations such as daily quota limitations on purchases, limitations on transferability of shares, pre-delivery or pre-validation of cash or securities to or by a broker which may impact a fund’s ability to trade portfolio securities in a timely manner and can negatively affect a fund’s returns. Only certain A-shares are eligible to be accessed through Stock Connect and these securities could lose their eligibility at any time. Stock Connect utilizes an omnibus clearing structure, and a fund’s shares will be registered in the custodian’s name on the Hong Kong Central Clearing and Settlement System. This may reduce a manager’s ability to effectively manage a fund’s holdings, including the potential enforcement of equity owner rights. B shares can only be traded by non-residents of the PRC or residents with an appropriate foreign currency account that meets certain requirements.

China’s foreign ownership limitations may result in limitations on investment or the return of profits if a fund purchases and sells shares of an issuer in which it owns 5% or more of the shares issued within a six-month period. It is unclear whether China will aggregate a fund’s holdings with other affiliated funds in determining the 5% ownership level. The restrictions on ownership and ability of Chinese regulatory authorities and Chinese issuers to suspend trading, their willingness to exercise this option in response to market volatility and other events, can negatively affect liquidity and volatility of the Chinese markets.

It is also possible to gain exposure to certain Chinese companies through legal structures known as Variable Interest Entities (VIEs). The VIE structure is designed to provide foreign investors with exposure to Chinese companies that operate in certain sectors in which China restricts and/or prohibits foreign investments, such as internet, media, education, and telecommunications. VIEs seek to establish claims to a China-based company’s profits and control of its assets through contractual arrangements. While VIEs are a longstanding industry practice, they are not formally recognized under Chinese law or approved by Chinese regulators. It is also uncertain whether Chinese officials or regulators will prohibit Chinese companies from accessing foreign investment through VIEs or remove VIEs’ ability to pass through economic and governance rights to foreign individuals and entities. The contractual arrangements with the VIE also may not be as effective in providing operational control as direct equity ownership. The Chinese equity owner(s) of a VIE could decide to breach the contractual arrangements and may have conflicting interests and fiduciary duties as compared to foreign investors in the shell company. Further, any breach or dispute under these contracts will likely fall under Chinese jurisdiction and law. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts through Chinese courts and/or arbitration bodies, would likely cause the VIE-structured holding(s) to suffer significant, detrimental, and possibly permanent loss, and in turn, adversely affect a fund’s returns and net asset value. Additionally, an investor’s rights may be limited with respect to the underlying Chinese operating company.

Accessing and Investing in the Chinese Bond Market. The People’s Bank of China has established a program that permits eligible foreign investors to invest directly in bonds traded on the Chinese Interbank Bond Market (CIBM). While the CIBM is relatively large and trading volumes are generally high, the market has similar risks as bond markets in other emerging market countries. A fund may invest in the bonds available on the CIBM through Bond Connect, which was established with the Hong Kong Monetary Authority as a way to permit overseas investors to trade in each other’s respective markets. Bond Connect provides a connection between mainland China- and Hong Kong-based financial institutions, permitting securities trading between the mainland China and Hong Kong markets electronically, thus eliminating the stricter restrictions that were present under previous access models.

Investing in securities traded on the CIBM through Bond Connect is subject to regulatory risks. The relevant rules, regulations, structure, terms, and a fund’s ability to access Bond Connect may be subject to change with minimal notice and any changes have the potential to be applied retroactively. For example, if Bond Connect is not operating or trading is otherwise suspended, a fund’s ability to trade bonds in a timely manner may be affected and there may be negative

impacts on the fund. Additionally, market volatility and possible lack of liquidity due to low trading volume on the CIBM may result in significant fluctuations in the prices of certain bonds traded on the CIBM. The bid-ask spreads of the prices of such securities may be large, and a fund may therefore incur significant costs and may suffer losses when selling such investments. Further, the bonds traded on the CIBM may be difficult or impossible to sell, which may impact a fund’s ability to acquire or dispose of such securities at their expected prices.

Bonds issued by Chinese companies or the Chinese government may be dollar denominated. These dollar-denominated bonds carry some of the same risks as RMB-denominated bonds traded through Bond Connect, but generally benefit from reduced currency risk since a fund does not need to engage in currency trading to settle the trade.

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 or market price for the relevant commodity on the last trading day of the contract and the price for the relevant commodity agreed upon at the outset of the contract. 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 an amount equal to the volatility in market value of a contract over a fixed period. If the value of the fund’s position declines, the fund will be required to make additional “variation margin” payments to the FCM to settle the change in value. If the value of the fund’s position increases, the FCM will be required to make additional “variation margin” payments to the fund to settle the change in value. This process is known as “marking-to-market” and is calculated on a daily basis. A futures transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund complies with

Rule 18f-4.

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 previously described in the case of futures contracts. A futures option transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund complies with Rule 18f-4.

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

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

A fund bears the risk that its advisor will incorrectly predict future market trends. If the advisor attempts to use a futures contract or a futures option as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the futures position will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the fund. Although hedging strategies involving futures products can reduce the risk 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.

Hybrid Instruments. A hybrid instrument, or hybrid, is an interest in an issuer that combines the characteristics of an equity security, a debt security, a commodity, and/or a derivative. A hybrid may have characteristics that, on the whole, more strongly suggest the existence of a bond, stock, or other traditional investment, but a hybrid may also have prominent features that are normally associated with a different type of investment. Moreover, hybrid instruments may be treated as a particular type of investment for one regulatory purpose (such as taxation) and may be simultaneously treated as a different type of investment for a different regulatory purpose (such as securities or commodity regulation). Hybrids can be used as an efficient means of pursuing a variety of investment goals, including increased total return, duration management, and currency hedging. Because hybrids combine features of two or more traditional investments and may involve the use of innovative structures, hybrids present risks that may be similar to, different from, or greater than those associated with traditional investments with similar characteristics.

Examples of hybrid instruments include convertible securities, which combine the investment characteristics of bonds and common stocks; perpetual bonds, which are structured like fixed income securities, have no maturity date, and may be characterized as debt or equity for certain regulatory purposes; contingent convertible securities, which are fixed

income securities that, under certain circumstances, either convert into common stock of the issuer or undergo a principal write-down by a predetermined percentage if the issuer’s capital ratio falls below a predetermined trigger level; and trust-preferred securities, which are preferred stocks of a special-purpose trust that holds subordinated debt of the corporate parent. Another example of a hybrid is a commodity-linked bond, such as a bond issued by an oil company that pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid would be a combination of a bond and a call option on oil.

In the case of hybrids that are structured like fixed income securities (such as structured notes), the principal amount or the interest rate is generally tied (positively or negatively) to the price of some commodity, currency, securities index, interest rate, or other economic factor (each, a benchmark). For some hybrids, the principal amount payable at maturity or the interest rate may be increased or decreased, depending on changes in the value of the benchmark. Other hybrids do not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark, thus magnifying movements within the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond with a fixed principal amount that pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes a fund to the credit risk of the issuer of the hybrids. Depending on the level of a fund’s investment in hybrids, these risks may cause significant fluctuations in the fund’s net asset value. Hybrid instruments may also carry liquidity risk since the instruments are often “customized” to meet the needs of an issuer or, sometimes, the portfolio needs of a particular investor, and therefore the number of investors that are willing and able to buy such instruments in the secondary market may be smaller than that for more traditional securities.

Certain issuers of hybrid instruments known as structured products may be deemed to be investment companies as defined in the 1940 Act. As a result, a fund’s investments in these products may be subject to the limitations described under the heading “Other Investment Companies.”

Industry Concentration. The SEC staff takes the position that a fund concentrates its investments if it invests more than 25% of its assets in any particular industry. (For this purpose investments do not include certain items such as cash, U.S. government securities, securities of other investment companies, and certain tax-exempt securities.)

Interfund Borrowing and Lending. The SEC has granted an exemption permitting registered open-end Vanguard funds to participate in Vanguard’s interfund lending program. This program allows the Vanguard funds to borrow money from and lend money to each other for temporary or emergency purposes. The program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the program unless it receives a more favorable interest rate than is typically available from a bank for a comparable transaction, (2) no fund may lend money if the loan would cause its aggregate outstanding loans through the program to exceed 15% of its net assets at the time of the loan, and (3) a fund’s interfund loans to any one fund shall not exceed 5% of the lending fund’s net assets. In addition, a Vanguard fund may participate in the program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The boards of trustees of the Vanguard funds are responsible for overseeing the interfund lending program. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Investing for Control. Each Vanguard fund invests in securities and other instruments for the sole purpose of achieving a specific investment objective. As such, a Vanguard fund does not seek to acquire, individually or collectively with any other Vanguard fund, enough of a company’s outstanding voting stock to have control over management decisions. A Vanguard fund does not invest for the purpose of controlling a company’s management.

Legal and Regulatory Risk. Vanguard funds and their advisors are subject to an extensive and complex set of laws and regulations. These laws and regulations have evolved rapidly in recent years and likely will continue to evolve. Changes and additions to laws and regulations can result in unintended or unexpected impacts, including impacts to the value of a fund’s investments, a fund’s investment strategy, and/or a fund’s ability to manage tax consequences. Changes in how laws and regulations are interpreted could similarly impact a fund. In addition, complying with new or changing laws or regulations generally can be expected to increase operational costs, which can have a negative impact on fund performance.

Market Disruption. Significant market disruptions, such as those caused by pandemics, natural or environmental disasters, war, acts of terrorism, or other events, can adversely affect local and global markets and normal market operations. Market disruptions may exacerbate political, social, and economic risks discussed above and in a fund’s prospectus. Additionally, market disruptions may result in increased market volatility; regulatory trading halts; closure of

domestic or foreign exchanges, markets, or governments; or market participants operating pursuant to business continuity plans for indeterminate periods of time. Such events can be highly disruptive to economies and markets and significantly impact individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of a fund’s investments and operation of a fund. These events could also result in the closure of businesses that are integral to a fund’s operations or otherwise disrupt the ability of employees of fund service providers to perform essential tasks on behalf of a fund.

Mortgage-Backed Securities. Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable from, mortgage loans secured by real property or instruments derived from such loans and may be based on different types of mortgages, including those on residential properties or commercial real estate. Mortgage-backed securities include various types of securities, such as government stripped mortgage-backed securities, adjustable rate mortgage-backed securities, and collateralized mortgage obligations.

Generally, mortgage-backed securities represent partial interests in pools of mortgage loans assembled for sale to investors by various governmental agencies, such as the Government National Mortgage Association (GNMA); by government-related organizations, such as the Federal National Mortgage Association (FNMA) and the Federal Home Loan Mortgage Corporation (FHLMC); and by private issuers, such as commercial banks, savings and loan institutions, and mortgage bankers. The average maturity of pass-through pools of mortgage-backed securities in which a fund may invest varies with the maturities of the underlying mortgage instruments. In addition, a pool’s average maturity may be shortened by unscheduled payments on the underlying mortgages. Factors affecting mortgage prepayments include the level of interest rates, the general economic and social conditions, the location of the mortgaged property, and the age of the mortgage. Because prepayment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted accurately.

Mortgage-backed securities may be classified as private, government, or government-related, depending on the issuer or guarantor. Private mortgage-backed securities represent interest in pass-through pools consisting principally of conventional residential or commercial mortgage loans created by nongovernment issuers, such as commercial banks, savings and loan associations, and private mortgage insurance companies. Private mortgage-backed securities may not be readily marketable. In addition, mortgage-backed securities have been subject to greater liquidity risk when worldwide economic and liquidity conditions deteriorate. U.S. government mortgage-backed securities are backed by the full faith and credit of the U.S. government. GNMA, the principal U.S. guarantor of these securities, is a wholly owned U.S. government corporation within the Department of Housing and Urban Development. Government-related mortgage-backed securities are not backed by the full faith and credit of the U.S. government. Issuers include FNMA and FHLMC, which are congressionally chartered corporations. In September 2008, the U.S. Treasury placed FNMA and FHLMC under conservatorship and appointed the Federal Housing Finance Agency (FHFA) to manage their daily operations. In addition, the U.S. Treasury entered into purchase agreements with FNMA and FHLMC to provide them with capital in exchange for senior preferred stock. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA. Participation certificates representing interests in mortgages from FHLMC’s national portfolio are guaranteed as to the timely payment of interest and principal by FHLMC. Private, government, or government-related entities may create mortgage loan pools offering pass-through investments in addition to those described above. The mortgages underlying these securities may be alternative mortgage instruments (i.e., mortgage instruments whose principal or interest payments may vary or whose terms to maturity may be shorter than customary).

Mortgage-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans. Prepayments of principal by mortgagors or mortgage foreclosures shorten the term of the mortgage pool underlying the mortgage-backed security. A fund’s ability to maintain positions in mortgage-backed securities is affected by the reductions in the principal amount of such securities resulting from prepayments. A fund’s ability to reinvest prepayments of principal at comparable yield is subject to generally prevailing interest rates at that time. The values of mortgage-backed securities vary with changes in market interest rates generally and the differentials in yields among various kinds of government securities, mortgage-backed securities, and asset-backed securities. In periods of rising interest rates, the rate of prepayment tends to decrease, thereby lengthening the average life of a pool of mortgages supporting a mortgage-backed security. Conversely, in periods of falling interest rates, the rate of prepayment tends to increase, thereby shortening the average life of such a pool. Because prepayments of principal generally occur when interest rates are declining, an investor, such as a fund, generally has to reinvest the proceeds of such prepayments at lower interest rates than those at which its assets were previously invested. Therefore, mortgage-backed securities have less potential for capital appreciation in periods of falling interest rates than other income-bearing securities of comparable maturity.

Mortgage-Backed Securities—Adjustable Rate Mortgage-Backed Securities. Adjustable rate mortgage-backed securities (ARMBSs) have interest rates that reset at periodic intervals. Acquiring ARMBSs permits a fund to participate in increases in prevailing current interest rates through periodic adjustments in the coupons of mortgages underlying the pool on which ARMBSs are based. Such ARMBSs generally have higher current yield and lower price fluctuations than is the case with more traditional fixed income debt securities of comparable rating and maturity. However, because the interest rates on ARMBSs are reset only periodically, changes in market interest rates or in the issuer’s creditworthiness may affect their value. In addition, when prepayments of principal are made on the underlying mortgages during periods of rising interest rates, a fund can reinvest the proceeds of such prepayments at rates higher than those at which they were previously invested. Mortgages underlying most ARMBSs, however, have limits on the allowable annual or lifetime increases that can be made in the interest rate that the mortgagor pays. Therefore, if current interest rates rise above such limits over the period of the limitation, a fund holding an ARMBS does not benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMBSs behave more like fixed income securities and less like adjustable rate securities and are thus subject to the risks associated with fixed income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

Mortgage-Backed Securities—Collateralized Mortgage Obligations. Collateralized mortgage obligations (CMOs) are mortgage-backed securities that are collateralized by whole loan mortgages or mortgage pass-through securities. The bonds issued in a CMO transaction are divided into groups, and each group of bonds is referred to as a “tranche.” Under the traditional CMO structure, the cash flows generated by the mortgages or mortgage pass-through securities in the collateral pool are used to first pay interest and then pay principal to the CMO bondholders. The bonds issued under a traditional CMO structure are retired sequentially as opposed to the pro-rata return of principal found in traditional pass-through obligations. Subject to the various provisions of individual CMO issues, the cash flow generated by the underlying collateral (to the extent it exceeds the amount required to pay the stated interest) is used to retire the bonds. Under a CMO structure, the repayment of principal among the different tranches is prioritized in accordance with the terms of the particular CMO issuance. The “fastest-pay” tranches of bonds, as specified in the prospectus for the issuance, would initially receive all principal payments. When those tranches of bonds are retired, the next tranche (or tranches) in the sequence, as specified in the prospectus, receives all of the principal payments until that tranche is retired. The sequential retirement of bond groups continues until the last tranche is retired. Accordingly, the CMO structure allows the issuer to use cash flows of long-maturity, monthly pay collateral to formulate securities with short, intermediate, and long final maturities and expected average lives and risk characteristics.

In recent years, new types of CMO tranches have evolved. These include floating rate CMOs, planned amortization classes, accrual bonds, and CMO residuals. These newer structures affect the amount and timing of principal and interest received by each tranche from the underlying collateral. Under certain of these new structures, given classes of CMOs have priority over others with respect to the receipt of prepayments on the mortgages. Therefore, depending on the type of CMOs in which a fund invests, the investment may be subject to a greater or lesser risk of prepayment than other types of mortgage-backed securities.

CMOs may include real estate mortgage investment conduits (REMICs). REMICs, which were authorized under the Tax Reform Act of 1986, are private entities formed for the purpose of holding a fixed pool of mortgages secured by an interest in real property. A REMIC is a CMO that qualifies for special tax treatment under the IRC and invests in certain mortgages principally secured by interests in real property. Investors may purchase beneficial interests in REMICs, which are known as “regular” interests, or “residual” interests. Guaranteed REMIC pass-through certificates (REMIC Certificates) issued by FNMA or FHLMC represent beneficial ownership interests in a REMIC trust consisting principally of mortgage loans or FNMA, FHLMC, or GNMA-guaranteed mortgage pass-through certificates. For FHLMC REMIC Certificates, FHLMC guarantees the timely payment of interest and also guarantees the payment of principal, as payments are required to be made on the underlying mortgage participation certificates. FNMA REMIC Certificates are issued and guaranteed as to timely distribution of principal and interest by FNMA.

The primary risk of CMOs is the uncertainty of the timing of cash flows that results from the rate of prepayments on the underlying mortgages serving as collateral and from the structure of the particular CMO transaction (i.e., the priority of the individual tranches). An increase or decrease in prepayment rates (resulting from a decrease or increase in mortgage interest rates) will affect the yield, the average life, and the price of CMOs. The prices of certain CMOs, depending on their structure and the rate of prepayments, can be volatile. Some CMOs may also not be as liquid as other securities.

Mortgage-Backed Securities—Hybrid ARMs. A hybrid adjustable rate mortgage (hybrid ARM) is a type of mortgage in which the interest rate is fixed for a specified period and then resets periodically, or floats, for the remaining mortgage term. Hybrid ARMs are usually referred to by their fixed and floating periods. For example, a 5/1 ARM refers to a mortgage with a 5-year fixed interest rate period, followed by a 1-year interest rate adjustment period. During the initial interest period (i.e., the initial five years for a 5/1 hybrid ARM), hybrid ARMs behave more like fixed income securities and are thus subject to the risks associated with fixed income securities. All hybrid ARMs have reset dates. A reset date is the date when a hybrid ARM changes from a fixed interest rate to a floating interest rate. At the reset date, a hybrid ARM can adjust by a maximum specified amount based on a margin over an identified index. Like ARMBSs, hybrid ARMs have periodic and lifetime limitations on the increases that can be made to the interest rates that mortgagors pay. Therefore, if during a floating rate period interest rates rise above the interest rate limits of the hybrid ARM, a fund holding the hybrid ARM does not benefit from further increases in interest rates.

Mortgage-Backed Securities—Mortgage Dollar Rolls. A mortgage dollar roll is a transaction in which a fund sells a mortgage-backed security to a dealer and simultaneously agrees to purchase a substantially similar security (but not the same security) in the future at a predetermined price on a predetermined date. A mortgage-dollar-roll program may be structured to simulate an investment in mortgage-backed securities at a potentially lower cost, or with potentially reduced administrative burdens, than directly holding mortgage-backed securities. For accounting purposes, each transaction in a mortgage dollar roll is viewed as a separate purchase and sale of a mortgage-backed security. These transactions may increase a fund’s portfolio turnover rate. The fund receives cash for a mortgage-backed security in the initial transaction and enters into an agreement that requires the fund to purchase a similar mortgage-backed security in the future.

The counterparty with which a fund enters into a mortgage-dollar-roll transaction is obligated to provide the fund with substantially similar securities to purchase as those originally sold by the fund. These securities generally must (1) be issued by the same agency and be part of the same program; (2) have similar original stated maturities; (3) have identical net coupon rates; and (4) satisfy “good delivery” requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within a certain percentage of the initial amount delivered. Mortgage dollar rolls will be used only if consistent with a fund’s investment objective and strategies and will not be used to change a fund’s risk profile.

Mortgage-Backed Securities—Stripped Mortgage-Backed Securities. Stripped mortgage-backed securities (SMBSs) are derivative multiclass mortgage-backed securities. SMBSs may be issued by agencies or instrumentalities of the U.S. government or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks, and special purpose entities formed or sponsored by any of the foregoing.

SMBSs are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). The price and yield to maturity on an IO class are extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on a fund’s yield to maturity from these securities. If the underlying mortgage assets experience greater than anticipated prepayments of principal, a fund may fail to recoup some or all of its initial investment in these securities, even if the security is in one of the highest rating categories.

Although SMBSs are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, these securities were only recently developed. As a result, established trading markets have not yet developed, and accordingly, these securities may be deemed “illiquid” and thus subject to a fund’s limitations on investment in illiquid securities.

Mortgage-Backed Securities—To Be Announced (TBA) Securities. A TBA securities transaction, which is a type of forward-commitment transaction, represents an agreement to buy or sell mortgage-backed securities with agreed-upon characteristics for a fixed unit price, with settlement on a scheduled future date, typically within 30 calendar days of the trade date. With TBA transactions, the particular securities (i.e., specified mortgage pools) to be delivered or received are not identified at the trade date; however, securities delivered to a purchaser must meet specified criteria, including face value, coupon rate, and maturity, and be within industry-accepted “good delivery” standards.

A fund may sell TBA securities to hedge its portfolio positions or to dispose of mortgage-backed securities it owns under delayed-delivery arrangements. A fund may sell a TBA that it does not hold (short sell) to manage portfolio risks while giving the fund more flexibility. The settlement date of a short TBA is not set, and the positions can be increased or decreased to ensure appropriate hedging ratios for the fund and may be offset by entering into an equal amount of TBA purchases. Proceeds of TBA securities sold are not received until the contractual settlement date.

For TBA purchases, a fund will maintain sufficient liquid assets (e.g., cash or marketable securities) until settlement date in an amount sufficient to meet the purchase price. Unsettled TBA securities are valued by an independent pricing service based on the characteristics of the securities to be delivered or received. A risk associated with TBA transactions is that at settlement, either the buyer fails to pay the agreed price for the securities or the seller fails to deliver the agreed securities. As the value of such unsettled TBA securities is assessed on a daily basis, parties mitigate such risk by, among other things, exchanging collateral as security for performance, performing a credit analysis of the counterparty, allocating transactions among numerous counterparties, and monitoring its exposure to each counterparty.

TBA securities 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 complies with Rule 18f-4.

Options. An option is a derivative. An option on a security (or index) is a contract that gives the holder of the option, in return for the payment of a “premium,” the right, but not the obligation, to buy from (in the case of a call option) or sell to (in the case of a put option) the writer of the option the security underlying the option (or the cash value of the index) at a specified exercise price prior to the expiration date of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price (in the case of a call option) or to pay the exercise price upon delivery of the underlying security (in the case of a put option). The writer of an option on an index has the obligation upon exercise of the option to pay an amount equal to the cash value of the index minus the exercise price, multiplied by the specified multiplier for the index option. The multiplier for an index option determines the size of the investment position the option represents. Unlike exchange-traded options, which are standardized with respect to the underlying instrument, expiration date, contract size, and strike price, the terms of over-the-counter (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 credit risk to the counterparty, whereas for exchange-traded, centrally cleared options, credit risk is mutualized through the involvement of the applicable clearing house.

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

Rule 18f-4.

If a trading market, in particular options, were to become unavailable, investors in those options (such as the funds) would be unable to close out their positions until trading resumes, and they may be faced with substantial losses if the

value of the underlying instrument moves adversely during that time. Even if the market were to remain available, there may be times when options prices will not maintain their customary or anticipated relationships to the prices of the underlying instruments and related instruments. Lack of investor interest, changes in volatility, or other factors or conditions might adversely affect the liquidity, efficiency, continuity, or even the orderliness of the market for particular options.

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

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

Examples of OTC swap agreements include, but are not limited to, interest rate swaps, credit default swaps, equity swaps, commodity swaps, foreign currency swaps, index swaps, excess return swaps, and total return swaps. Most OTC 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 an OTC 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. OTC swap agreements allow for a wide variety of transactions. For example, fixed rate payments may be exchanged for floating rate payments; U.S. dollar-denominated payments may be exchanged for payments denominated in a different currency; and payments tied to the price of one asset, reference rate, or index may be exchanged for payments tied to the price of another asset, reference rate, or index.

An OTC option on an OTC 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 OTC 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. OTC 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 an OTC 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.

OTC swap agreements may be subject to liquidity risk, which exists when a particular swap is difficult to purchase or sell. If an OTC 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, OTC swap transactions may be subject to a fund’s limitation on investments in illiquid securities.

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

Because certain OTC 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 OTC swaps have the potential for unlimited loss, regardless of the size of the initial investment. A leveraged OTC swap transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund complies with Rule 18f-4.

Like most other investments, OTC 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 OTC swap positions for the fund. If the advisor attempts to use an OTC swap as a hedge against, or as a substitute for, a portfolio investment, the fund will be exposed to the risk that the OTC 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 OTC 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 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 an OTC 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.

Other Investment Companies. A fund may invest in other investment companies, including ETFs, non-exchange traded U.S. registered open-end investment companies (mutual funds), and closed-end investment companies, to the extent permitted by applicable law or SEC exemption. Under Section 12(d)(1) of the 1940 Act, a fund may invest up to 10% of its assets in shares of investment companies generally and up to 5% of its assets in any one investment company, as long as no investment represents more than 3% of the voting stock of an acquired investment company. In addition, no funds for which Vanguard acts as an advisor may, in the aggregate, own more than 10% of the voting stock of a closed-end investment company. SEC Rule 12d1-4 under the 1940 Act permits registered investment companies to invest in other registered investment companies beyond the limits in Section 12(d)(1), subject to certain conditions, including that funds with different investment advisors must enter into a fund of funds investment

agreement. Rule 12d1-4 is also designed to limit the use of complex fund structures. Under Rule 12d1-4, an acquired fund is prohibited from purchasing or otherwise acquiring the securities of another investment company or private fund if, immediately after the purchase, the securities of investment companies and private funds owned by the acquired fund have an aggregate value in excess of 10% of the value of the acquired fund’s total assets, subject to certain limited exceptions. Accordingly, to the extent a fund’s shares are sold to other investment companies in reliance on

Rule 12d1-4, the acquired fund will be limited in the amount it could invest in other investment companies and private funds. If a fund invests in other investment companies, shareholders will bear not only their proportionate share of the fund’s expenses (including operating expenses and the fees of the advisor), but they also may indirectly bear similar expenses of the underlying investment companies. Certain investment companies, such as business development companies (BDCs), are more akin to operating companies and, as such, their expenses are not direct expenses paid by fund shareholders and are not used to calculate the fund’s net asset value. SEC rules nevertheless require that any expenses incurred by a BDC be included in a fund’s expense ratio as “Acquired Fund Fees and Expenses.” The expense ratio of a fund that holds a BDC will thus overstate what the fund actually spends on portfolio management, administrative services, and other shareholder services by an amount equal to these Acquired Fund Fees and Expenses. The Acquired Fund Fees and Expenses are not included in a fund’s financial statements, which provide a clearer picture of a fund’s actual operating expenses. Shareholders would also be exposed to the risks associated not only with the investments of the fund but also with the portfolio investments of the underlying investment companies. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that typically trade on a stock exchange or over-the-counter at a premium or discount to their net asset value. Others are continuously offered at net asset value but also may be traded on the secondary market.

A fund may be limited to purchasing a particular share class of other investment companies (underlying funds). In certain cases, an investor may be able to purchase lower-cost shares of such underlying funds separately, and therefore be able to construct, and maintain over time, a similar portfolio of investments while incurring lower overall expenses.

Ownership Limitations and Regulatory Relief. As the Vanguard funds continue to grow, they may be increasingly impacted by ownership limitations that apply to certain securities held by the Vanguard funds (“limited securities”). An ownership limitation restricts the amount of a security that funds within the same fund complex or funds advised by the same investment advisor can own. These limitations may apply even where an external manager or different affiliate of Vanguard provides investment advisory services to a fund. Ownership restrictions and limitations can apply to certain

industries (for example, banking, insurance, and utilities), certain issuers (who may, for example, have mechanisms such as poison pills in place to prevent takeovers), or certain transactions, and will also vary significantly in different contexts. A fund can be subject to more than one ownership limitation depending on its holdings, and each ownership limitation can impact multiple securities held by a fund.

Ownership limitations can restrict or impair a fund’s investment activities in a variety of ways. To meet the requirements of a limitation or restriction, a fund may be unable to purchase or directly hold a security the fund would otherwise purchase or hold if the limitation did not apply. For index funds, this means a fund may not be able to track its index as closely as it would if it was not subject to an ownership limitation because the fund cannot buy its desired amount of an impacted security. For actively managed funds, this means a fund may miss an opportunity to invest in an impacted security that the fund’s investment advisor otherwise would invest in if the fund were not subject to an ownership limitation. These types of restrictions could negatively impact a fund’s performance.

When a Vanguard fund is subject to an ownership limitation, Vanguard or the fund typically will seek permission to exceed the limitation. However, there is no guarantee that permission will be granted, or that, once granted, it will not be modified or revoked at a later date. If this happens, the fund could be required to sell or otherwise dispose of holdings in one or more issuers to comply with limitations. In the event that a regulator revokes relief from ownership limitations for the Vanguard funds and other large fund complexes at the same time, there could be significant negative market impacts in the applicable industries and increased volatility in the share prices of the relevant securities. Sudden loss of ownership limitation relief relating to one or more limited securities could potentially result in wider bid-ask spreads and premium/discounts in ETF shares, and in extreme scenarios, impact the trading of ETF shares.

In order to obtain permission to exceed an ownership limitation, Vanguard may have to agree to certain conditions that will impact its ability to exercise rights on behalf of funds. For example, Vanguard may be required to agree to vote proxies in a certain way for any securities Vanguard funds hold that exceed a particular ownership limitation.

For situations in which the Vanguard funds do not have or are unable to obtain permission to exceed ownership limitations, the Vanguard funds and their advisors have adopted policies designed to allocate ownership of impacted securities across applicable Vanguard products in a manner that is fair and equitable over time in order to minimize the potential conflicts of interest that could arise in making such allocation determinations. These allocation policies could result in certain Vanguard products obtaining zero or reduced direct exposure to one or more impacted securities and/or indirect exposure to impacted securities. In order to obtain indirect exposure, funds may use derivatives (such as total return swaps) or invest in totally held subsidiaries that hold the impacted securities. Both of these ways of obtaining indirect exposure are more costly than owning securities of the issuer directly. Depending on the circumstances, certain Vanguard funds may incur and bear the costs associated with transactions entered into for these purposes that other Vanguard funds do not incur and bear. With respect to an index fund, these added costs could also result in tracking error relative to the fund’s target index. There is no guarantee that laws and regulations always will allow that indirect exposure to limited securities may be omitted for purposes of determining the Vanguard funds’ exposure to limited securities and compliance with the applicable ownership limitations. In such circumstances, the Vanguard funds could not use these techniques and would be required to sell down the indirect and/or direct holdings in the applicable limited securities.

In addition, there is no guarantee that the Vanguard funds will be able to obtain some or all of the derivatives that the funds want in order to gain indirect exposure to a limited security. This limited availability of derivatives may impact the ability of a fund to meet its investment objective or invest in accordance with its investment strategy, and/or have additional impacts to fund performance. Additionally, funds that use derivatives for indirect exposure are subject to derivatives-related risks.

Ownership limitations and the use of derivatives to address ownership limitations could result in unanticipated tax consequences to a fund that may affect the amount, timing, and character of distributions to shareholders. The taxation of derivatives can be complex and, depending upon the type and amount of derivatives employed by a fund, the tax consequences of using derivatives could be worse than the tax consequences that result from direct exposure to impacted securities.

Ownership limitations are highly complex. It is possible that, despite a fund’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit.

Preferred Stock. Preferred stock represents an equity or ownership interest in an issuer. Preferred stock normally pays dividends at a specified rate and has precedence over common stock in the event the issuer is liquidated or declares bankruptcy. However, in the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take

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

Private Equity. Private equity is equity capital that is not quoted on a public exchange. Acquiring private equity involves making investments directly into private companies or conducting buyouts of public companies that result in a delisting of public equity. Capital for private equity can be used to fund new technologies, expand working capital within an owned company, make acquisitions, or to strengthen a balance sheet. Private equity securities should be regarded as illiquid, as they are not listed on an exchange and generally are not widely transferable. By their nature, investments in privately held companies tend to be riskier than investments in publicly traded companies. Generally, there will be no readily available market for private equity investments and, accordingly, most such investments are difficult to value and can be difficult to exit.

Real Estate Investment Trusts (REITs). An equity REIT owns real estate properties directly and generates income from rental and lease payments. Equity REITs also have the potential to generate capital gains as properties are sold at a profit. A mortgage REIT makes construction, development, and long-term mortgage loans to commercial real estate developers and earns interest income on these loans. A hybrid REIT holds both properties and mortgages. To avoid taxation at the corporate level, REITs must distribute most of their earnings to shareholders.

Investments in REITs are subject to many of the same risks as direct investments in real estate. In general, real estate values can be affected by a variety of factors, including, but not limited to, supply and demand for properties, general or local economic conditions, and the strength of specific industries that rent properties. Ultimately, a REIT’s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. For example, rental income could decline because of extended vacancies, increased competition from nearby properties, tenants’ failure to pay rent, regulatory limitations on rents, fluctuations in rental income, variations in market rental rates, or incompetent management. Property values could decrease because of overbuilding in the area, environmental liabilities, uninsured damages caused by natural disasters, a general decline in the neighborhood, losses because of casualty or condemnation, increases in property taxes, or changes in zoning laws.

The value of a REIT may also be affected by changes in interest rates. Rising interest rates generally increase the cost of financing for real estate projects, which could cause the value of an equity REIT to decline. During periods of declining interest rates, mortgagors may elect to prepay mortgages held by mortgage REITs, which could lower or diminish the yield on the REIT. REITs are also subject to heavy cash-flow dependency, default by borrowers, and changes in tax and regulatory requirements. In addition, a REIT may fail to meet the requirements for qualification and taxation as a REIT under the IRC and/or fail to maintain exemption from the 1940 Act.

Reliance on Service Providers, Data Providers, and Other Technology. Vanguard funds rely upon the performance of service providers to execute several key functions, which may include functions integral to a fund’s operations. Failure by any service provider to carry out its obligations to a fund could disrupt the business of the fund and could have an adverse effect on the fund’s performance. A fund’s service providers’ reliance on certain technology or information vendors (e.g., trading systems, investment analysis tools, benchmark analytics, and tax and accounting tools) could also adversely affect a fund and its shareholders. For example, a fund’s investment advisor may use models and/or data with respect to potential investments for the fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance upon such models or data expose a fund to potential risks.

Repurchase Agreements. A repurchase agreement is an agreement under which a fund acquires a debt 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 bank, a broker, a dealer, or another counterparty that meets minimum credit requirements 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, dealer, or other counterparty that meets minimum credit requirements 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 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 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/Investments (including Private Placements). Illiquid securities/investments are investments that a fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. The SEC generally limits aggregate holdings of illiquid securities/investments by a mutual fund to 15% of its net assets (5% for money market funds). A fund may experience difficulty valuing and selling illiquid securities/investments 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) certain loan interests and other direct debt instruments,

(5)certain municipal lease obligations, (6) private equity investments, (7) commercial paper issued pursuant to Section 4(a)(2) of the 1933 Act, and (8) securities whose disposition is restricted under the federal securities laws. Illiquid securities/investments may include restricted, privately placed securities (such as private investments in public equity (PIPEs) or special purpose acquisition companies (SPACs)) that, under the federal securities laws, generally may be resold only to qualified institutional buyers. If a market develops for a restricted security held by a fund, it may be treated as a liquid security in accordance with guidelines approved by the board of trustees.

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. In addition to the risk of such a loss, fees charged to the fund may exceed the return the fund earns from investing the proceeds received from the reverse repurchase agreement transaction. A reverse repurchase agreement may be considered a borrowing transaction for purposes of the 1940 Act. A reverse repurchase agreement transaction will not be considered to constitute the issuance, by a fund, of a “senior security,” as that term is defined in Section 18(g) of the 1940 Act, and therefore such transaction will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by a fund, if the fund complies with Rule 18f-4. A fund will enter into reverse repurchase agreements only with parties whose creditworthiness has been reviewed and found satisfactory by the advisor. If the buyer in a reverse repurchase agreement becomes insolvent or files for bankruptcy, a fund’s use of proceeds from the sale may be restricted while the other party or its trustee or receiver determines if it will honor the fund’s right to repurchase the securities. If the fund is unable to recover the securities it sold in a reverse repurchase agreement, it would realize a loss equal to the difference between the value of the securities and the payment it received for them.

Securities Lending. A fund may lend its securities to financial institutions (typically brokers, dealers, and banks) to generate income for the fund. There are certain risks associated with lending securities, including counterparty, credit, market, regulatory, tax, and operational risks. Vanguard considers the creditworthiness of the borrower, among other factors, in making decisions with respect to the lending of securities, subject to oversight by the board of trustees. 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 certain types of foreign securities, as well as certain types of borrowers that are subject to global regulatory regimes. If a fund is not able to recover the securities lent, the fund may sell the collateral and

purchase a replacement security in the market. Collateral investments are subject to market appreciation or depreciation. The value of the collateral could decrease below the value of the replacement investment by the time the replacement investment is purchased. Currently, a fund invests cash collateral into Vanguard Market Liquidity Fund, an affiliated money market fund that invests primarily in high-quality, short-term money market instruments.

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 331⁄3% of the fund’s total assets and require that (1) the borrower pledge and maintain with the fund collateral consisting of cash, an irrevocable letter of credit, or securities issued or guaranteed by the U.S. government having at all times not less than 100% of the value of the securities lent; (2) the borrower add to such collateral whenever the price of the securities lent rises (i.e., the borrower “marks to market” on a daily basis); (3) the loan be made subject to termination by the fund at any time; and (4) the fund receives reasonable interest on the loan (which may include the fund 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 a fund will comply with any other applicable regulatory requirements. At the present time, the SEC does not object if an investment company pays reasonable negotiated fees in connection with lent securities, so long as such fees are set forth in a written contract and approved by the investment company’s trustees. In addition, voting rights pass with the lent securities, but if a fund has knowledge that a material event will occur affecting securities on loan, and in respect to which the holder of the securities will be entitled to vote or consent, the lender must be entitled to call the loaned securities in time to vote or consent. A fund bears the risk that there may be a delay in the return of the securities, which may impair the fund’s ability to vote on such a matter. See Tax Status of the Funds for information about certain tax consequences related to a fund’s securities lending activities.

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

Tax Matters—Federal Tax Discussion. Discussion herein of U.S. federal income tax matters summarizes some of the important, generally applicable U.S. federal tax considerations relevant to investment in a fund based on the IRC, U.S. Treasury regulations, and other applicable authorities. These authorities are subject to change by legislative, administrative, or judicial action, possibly with retroactive effect. Each Fund has not requested and will not request an advance ruling from the Internal Revenue Service (IRS) as to the U.S. federal income tax matters discussed in this Statement of Additional Information. In some cases, a fund’s tax position may be uncertain under current tax law and an adverse determination or future guidance by the IRS with respect to such a position could adversely affect the fund and its shareholders, including the fund’s ability to continue to qualify as a regulated investment company or to continue to pursue its current investment strategy. A shareholder should consult their tax professional for information regarding the particular situation and the possible application of U.S. federal, state, local, foreign, and other taxes.

Tax Matters—Federal Tax Treatment of Derivatives, Hedging, and Related Transactions. A fund’s transactions in derivative instruments (including, but not limited to, options, futures, forward contracts, and swap agreements), as well as any of the fund’s hedging, short sale, securities loan, or similar transactions, may be subject to one or more special tax rules that accelerate income to the fund, defer losses to the fund, cause adjustments in the holding periods of the fund’s securities, convert long-term capital gains into short-term capital gains, or convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing, and character of distributions to shareholders.

Because these and other tax rules applicable to these types of transactions are in some cases uncertain under current law, an adverse determination or future guidance by the IRS with respect to these rules (which determination or guidance could be retroactive) may affect whether a fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid a fund-level tax.

Tax Matters—Federal Tax Treatment of Futures Contracts. For federal income tax purposes, a fund generally must recognize, as of the end of each taxable year, any net unrealized gains and losses on certain futures contracts, as well as any gains and losses actually realized during the year. In these cases, any gain or loss recognized with respect to a futures contract is considered to be 60% long-term capital gain or loss and 40% short-term capital gain or loss, without regard to the holding period of the contract. Gains and losses on certain other futures contracts (primarily non-U.S. futures contracts) are not recognized until the contracts are closed and are treated as long-term or short-term,

depending on the holding period of the contract. Sales of futures contracts that are intended to hedge against a change in the value of securities held by a fund may affect the holding period of such securities and, consequently, the nature of the gain or loss on such securities upon disposition. A fund may be required to defer the recognition of losses on one position, such as futures contracts, to the extent of any unrecognized gains on a related offsetting position held by the fund.

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

Tax Matters—Federal Tax Treatment of Non-U.S. Currency Transactions. Special rules generally govern the federal income tax treatment of a fund’s transactions in the following: non-U.S. currencies; non-U.S. currency-denominated debt obligations; and certain non-U.S. currency options, futures contracts, forward contracts, and similar instruments.

Accordingly, if a fund engages in these types of transactions it may have ordinary income or loss to the extent that such income or loss results from fluctuations in the value of the non-U.S. currency concerned. Such ordinary income could accelerate fund distributions to shareholders and increase the distributions taxed to shareholders as ordinary income. Any ordinary loss so created will generally reduce ordinary income distributions and, in some cases, could require the recharacterization of prior ordinary income distributions. Net ordinary losses cannot be carried forward by the fund to offset income or gains realized in subsequent taxable years.

Any gain or loss attributable to the non-U.S. currency component of a transaction engaged in by a fund that is not subject to these special currency rules (such as foreign equity investments other than certain preferred stocks) will generally be treated as a capital gain or loss and will not be segregated from the gain or loss on the underlying transaction.

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

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

Tax Matters—Market Discount or Premium. The price of a bond purchased after its original issuance may reflect market discount or premium. Depending on the particular circumstances, market discount may affect the tax character and amount of income required to be recognized by a fund holding the bond. In determining whether a bond is purchased with market discount, certain de minimis rules apply. Premium is generally amortizable over the remaining term of the bond. Depending on the type of bond, premium may affect the amount of income required to be recognized by a fund holding the bond and the fund’s basis in the bond.

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

Tax Matters—Real Estate Mortgage Investment Conduits. If a fund invests directly or indirectly, including through a REIT or other pass-through entity, in residual interests in real estate mortgage investment conduits (REMICs) or equity interests in taxable mortgage pools (TMPs), a portion of the fund’s income that is attributable to a residual interest in a

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

Tax Matters—Tax Considerations for Non-U.S. Investors. U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments made by non-U.S. investors in Vanguard funds. Certain properly reported distributions of qualifying interest income or short-term capital gain made by a fund to its non-U.S. investors are exempt from U.S. withholding taxes, provided the investors furnish valid tax documentation (i.e., IRS Form W-8) certifying as to their non-U.S. status.

A fund is permitted, but is not required, to report any of its distributions as eligible for such relief, and some distributions (e.g., distributions of interest a fund receives from non-U.S. issuers) are not eligible for this relief. For some funds, Vanguard has chosen to report qualifying distributions and apply the withholding exemption to those distributions when made to non-U.S. shareholders who invest directly with Vanguard. For other funds, Vanguard may choose not to apply the withholding exemption to qualifying fund distributions made to direct shareholders, but may provide the reporting to such shareholders. In these cases, a shareholder may be able to reclaim such withholding tax directly from the IRS.

If shareholders hold fund shares (including ETF shares) through a broker or intermediary, their broker or intermediary may apply this relief to properly reported qualifying distributions made to shareholders with respect to those shares. If a shareholder’s broker or intermediary instead collects withholding tax where the fund has provided the proper reporting, the shareholder may be able to reclaim such withholding tax from the IRS. Please consult your broker or intermediary regarding the application of these rules.

This relief does not apply to any withholding required under the Foreign Account Tax Compliance Act (FATCA), which generally requires a fund to obtain information sufficient to identify the status of each of its shareholders. If a shareholder fails to provide this information or otherwise fails to comply with FATCA, a fund may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on fund distributions. Please consult your tax advisor for more information about these rules.

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

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

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

Time Deposits. Time deposits are subject to the same risks that pertain to domestic issuers of money market instruments, most notably credit risk (and, to a lesser extent, income risk, market risk, and liquidity risk). Additionally, time deposits of foreign branches of U.S. banks and foreign branches of foreign banks may be subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of U.S. dollars, from flowing across its borders. Other risks include adverse political and economic developments, the extent

and quality of government regulation of financial markets and institutions, the imposition of foreign withholding taxes, and expropriation or nationalization of foreign issuers. However, time deposits of such issuers will undergo the same type of credit analysis as domestic issuers in which a Vanguard fund invests and will have at least the same financial strength as the domestic issuers approved for the fund.

Warrants. Warrants are instruments that give the holder the right, but not the obligation, to buy an equity security at a specific price for a specific period of time. Changes in the value of a warrant do not necessarily correspond to changes in the value of its underlying security. The price of a warrant may be more volatile than the price of its underlying security, and a warrant may offer greater potential for capital appreciation as well as capital loss. Warrants do not entitle a holder to dividends or voting rights with respect to the underlying security and do not represent any rights in the assets of the issuing company. A warrant ceases to have value if it is not exercised prior to its expiration date. These factors can make warrants more speculative than other types of investments. Other kinds of warrants exist, including, but not limited to, warrants linked to countries’ economic performance or to commodity prices such as oil prices. These warrants may be subject to risk from fluctuation of underlying assets or indexes, as well as credit risk that the issuer does not pay on the obligations and risk that the data used for warrant payment calculation does not accurately reflect the true underlying commodity price or economic performance.

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 complies with Rule 18f-4.

SHARE PRICE

Each Fund’s share price, also known as net asset value (NAV), is typically calculated as of the close of regular trading on the New York Stock Exchange (NYSE), generally 4 p.m., Eastern time, on each day that the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, each Fund reserves the right to treat such day as a business day and calculate NAVs as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard’s discretion), generally 4 p.m., Eastern time. The NAV per share for Vanguard Developed Markets ex-US Value Index ETF, and Vanguard Developed Markets ex-US Growth Index ETF is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Funds do not sell or redeem shares. However, on those days the value of a Fund’s assets may be affected to the extent that the Fund holds securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

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

PURCHASE AND REDEMPTION OF SHARES

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 and (2) alter, impose, discontinue, or waive any purchase fee, redemption fee, account service fee, or other fee charged to a shareholder or a group of shareholders. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, Vanguard believes they are in the best interest of a fund.

Account Restrictions

Vanguard reserves the right to: (1) redeem all or a portion of a fund/account to meet a legal obligation, including tax withholding, tax lien, garnishment order, or other obligation imposed on your account by a court or government agency;

(2)redeem shares, close an account, or suspend account privileges, features, or options in the case of threatening conduct or activity; (3) redeem shares, close an account, or suspend account privileges, features, or options if Vanguard believes or suspects that not doing so could result in a suspicious, fraudulent, or illegal transaction; (4) place restrictions on the ability to redeem any or all shares in an account if it is required to do so by a court or government agency; (5) place restrictions on the ability to redeem any or all shares in an account if Vanguard believes that doing so will prevent fraud or financial exploitation or abuse, or will protect vulnerable investors; (6) 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; and (7) freeze any account and/or suspend account services upon initial notification to Vanguard of the death of an account owner.

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

MANAGEMENT OF THE FUNDS

Vanguard

Each Fund is part of the Vanguard group of investment companies, which consists of over 200 funds. Each fund is a series of a Delaware statutory trust. The funds obtain virtually all of their corporate management, administrative, and distribution services through the trusts’ jointly owned subsidiary, Vanguard. Vanguard may contract with certain third- party service providers to assist Vanguard in providing certain administrative and/or accounting services with respect to the funds, subject to Vanguard’s oversight. Vanguard also provides investment advisory services to certain Vanguard funds. All of these services are provided at Vanguard’s total cost of operations pursuant to the Fifth Amended and Restated Funds’ Service Agreement (the Agreement).

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. In rendering investment management services to the funds, Vanguard may also use the resources of its foreign wholly owned subsidiaries that are not registered as investment advisers with the SEC, using “participating affiliate arrangements.” Participating affiliate arrangements are arrangements used in reliance on guidance of the staff of the SEC and recognized by the SEC that allow a US-registered investment adviser Vanguard to use investment management resources of unregistered affiliates, subject to the regulatory supervision of the registered adviser. Each fund (other than a fund of funds) pays its share of Vanguard’s total expenses, which are allocated among the funds under methods approved by the board of trustees of each fund. In addition, each fund bears its own direct expenses, such as legal, auditing, and custodial fees.

Pursuant to an agreement between Vanguard and JPMorgan Chase Bank, N.A. (JPMorgan), JPMorgan provides services for the Funds. These services include, but are not limited to: (i) the calculation of such funds’ daily NAVs and (ii) the furnishing of financial reports. The fees paid to JPMorgan under this agreement are based on a combination of

flat and asset based fees.

Pursuant to an agreement between Vanguard and State Street Bank and Trust Company (State Street), State Street provides services for the Funds. These services include, but are not limited to: (i) the calculation of such funds’ daily NAVs and (ii) the furnishing of financial reports. The fees paid to State Street under this agreement are based on a combination of flat and asset based fees. As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore have not incurred any fees.

The funds’ officers are also employees of Vanguard.

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

Vanguard was established and operates under the Agreement. The Agreement provides that each Vanguard fund may be called upon to invest up to 0.40% of its net assets in Vanguard. The amounts that each fund has invested are adjusted from time to time in order to maintain the proportionate relationship between each fund’s relative net assets and its contribution to Vanguard’s capital.

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore had not contributed capital to Vanguard.

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, (7) review and evaluation of advisory and other services provided to the funds by third parties, and (8) such other services necessary to operate the funds at the lowest reasonable cost in accordance with the Agreement.

Distribution. Vanguard Marketing Corporation, 100 Vanguard Boulevard, Malvern, PA 19355, a wholly owned subsidiary of Vanguard, is the principal underwriter for the funds and in that capacity performs and finances marketing, promotional, and distribution activities (collectively, marketing and distribution activities) that are primarily intended to result in the sale of the funds’ shares. VMC offers shares of each fund for sale on a continuous basis and will use all reasonable efforts in connection with the distribution of shares of the funds. VMC performs marketing and distribution activities 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 its average month-end net assets. Each fund’s contribution to these marketing and distribution expenses helps to maintain and enhance the attractiveness and viability of the Vanguard complex as a whole, which benefits all of the funds and their shareholders.

VMC’s principal marketing and distribution expenses are for advertising, promotional materials, and marketing personnel. Other marketing and distribution activities of an administrative nature 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.

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, 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 does make fixed dollar payments to financial service providers when 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 also makes fixed dollar payments to financial service providers for data regarding funds, such as statistical information regarding sales of fund shares. In addition, VMC makes fixed dollar payments for expenses associated with financial service providers’ use of Vanguard’s funds including, but not limited to, the use of funds in model portfolios. These payments may be used for services including, but not limited to, technology support and development; platform support and development; due diligence related to products used on a platform; legal, regulatory, and compliance expenses related to a platform; and other platform-related services.

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 policy 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 and fixed dollar payments as described above, may influence applicable 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, relationships, or payments 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.

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex- US Growth Index ETF had not commenced operations and therefore had not incurred any annual shared fund operation expenses.

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 services and oversight. These groups provide the trustees with regular reports regarding investment, valuation, liquidity, and compliance, as well as the risks associated with each. The trustees also oversee risk management for the funds through regular interactions with the funds’ internal and external auditors.

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

The Audit and Risk Committee of the board, which is composed of Sarah Bloom Raskin, Peter F. Volanakis, Tara Bunch, and Mark Loughridge, each of whom is an independent trustee, oversees the management of financial risks and controls and enterprise-wide risk management. The Audit and Risk 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 committee also serves as a channel of communication between risk management personnel and the board with respect to enterprise-wide risk management. Vanguard’s head of internal audit reports directly to the Audit and Risk Committee. The committee receives reports in writing and in person on a regular basis from Vanguard’s head of internal audit and Vanguard’s chief risk officer. Although the Audit and Risk Committee is responsible for overseeing the management of financial risks and controls and enterprise-wide risk management, the entire board is regularly informed of these risks through the committee’s reports.

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

School of Engineering, and Santa Clara University’s

School of Business.

With the exception of Mr. Ramji, all of the trustees are independent. The trustees designate a chair of the board. Mr. Loughridge, an independent trustee, serves as chair. The independent chair is a spokesperson and principal point of contact for the trustees, including the independent trustees, and is responsible for coordinating the activities of the trustees, including calling regular executive sessions of the independent trustees, developing the agenda of each board meeting together with the chief executive officer, and chairing the meetings of the trustees.

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

■Audit and Risk Committee: This committee oversees the accounting and financial reporting policies, the systems of internal controls, the independent audits of each fund, and enterprise-wide risk management. Ms. Raskin and Mr. Volanakis co-chair the committee. The following independent trustees serve as members of the committee: Ms. Bunch and Mr. Loughridge.

■Compensation Committee: This committee oversees the compensation programs established by each fund for the benefit of its trustees. Mr. Reid chairs the committee. The following independent trustees serve as members of the committee: Mr. Loughridge, Mr. Murphy, and Ms. Patterson.

■Independent Governance Committee: This committee assists the board in fulfilling its responsibilities and is empowered to exercise board powers in the intervals between board meetings unless such action is prohibited by applicable law or Trust bylaws. Mr. Loughridge chairs the committee. The following independent trustees serve as members of the committee: Mr. Pastor, Mr. Perold, Ms. Raskin, and Mr. Volanakis.

■Investment Committees: These committees oversee the investment advisors to the funds. The committees are

responsible for: approving the funds’ investment advisory agreements and allocation of assets among advisors, overseeing the funds’ proxy voting, and approving policies used to vote fund proxies. Mr. Pastor and Mr. Malpass each chair one of the committees and each trustee serves on at least one of the two investment committees, with each committee comprised of a majority of the funds’ independent trustees.

■Nominating Committee: This committee nominates candidates for election to the board of trustees of each fund. The committee also has the authority to recommend the removal of any trustee. Ms. Bunch chairs the committee. The following independent trustees serve as members of the committee: Mr. Loughridge, Mr. Malpass, Dr. Thomas, and Ms. Venneman. The Nominating Committee will consider shareholder recommendations for trustee nominees. Shareholders may send recommendations to Ms. Bunch, chair of the committee.

Trustees retire in accordance with the funds’ governing documents and policies, and typically by age 75.

Trustee Compensation

The same individuals serve as trustees of all Vanguard funds and each fund pays a proportionate share of the trustees’ compensation. Vanguard 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 two ways:

■The independent trustees receive an annual fee for their service to the funds, which is subject to reduction based on absences from scheduled board meetings.

■The independent trustees are reimbursed for the travel and other expenses that they incur in attending board meetings.

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

Compensation Table. The following table provides compensation details for each of the trustees. We list the amounts paid as compensation by the Funds for each trustee. In addition, the table shows the total amount of compensation paid to each trustee by all Vanguard funds.

VANGUARD WORLD FUND

Portfolio Holdings Disclosure Policies and Procedures

Introduction

Vanguard and the boards of trustees of the Vanguard funds (the 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, sub-advisor, distributor, or any affiliated person of the fund, its investment advisor, sub-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 Ethical Conduct, 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 equivalent investments, derivatives, and other investment positions (collectively, other investment positions) held by the fund.

Online Disclosure of Complete Portfolio Holdings

Actively managed equity funds, unless otherwise stated, generally will seek to disclose complete portfolio holdings as of the end of the most recent calendar quarter online at vanguard.com, 30 calendar days after the end of the calendar quarter. Actively managed fixed income funds will seek to disclose complete portfolio holdings as of the end of the most recent month online at vanguard.com, 15 calendar days after the end of the month. Each Vanguard fund relying on Rule 6c-11 under the 1940 Act (e.g., standalone ETFs) generally will seek to disclose complete portfolio holdings, including other investment positions, at the beginning of each business day. These portfolio holdings, including other investment positions, will be disclosed online at vanguard.com. In accordance with Rule 2a-7 under the 1940 Act, each of the Vanguard money market funds will disclose the fund’s complete portfolio holdings as of the last business day of the prior month online at vanguard.com no later than the fifth business day of the current month. The complete portfolio holdings information for money market funds will remain available online for at least six months after the initial posting. Each Vanguard index fund, other than those Vanguard index funds relying on Rule 6c-11 under the 1940 Act (e.g., standalone ETFs) generally will seek to disclose the fund’s complete portfolio holdings as of the end of the most recent month online at vanguard.com, 15 calendar days after the end of the month.

Online disclosure of complete portfolio holdings is made to all categories of persons, including individual investors, institutional investors, intermediaries, third-party service providers, rating and ranking organizations, affiliated persons of a Vanguard fund, and all other persons. Vanguard will review complete portfolio holdings before disclosure is made and, except with respect to the complete portfolio holdings of the Vanguard money market funds, may withhold any portion of the fund’s complete portfolio holdings from disclosure when deemed to be in the best interests of the fund after consultation with a Vanguard fund’s investment advisor.

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

Vanguard, for legitimate business purposes, may disclose Vanguard fund complete portfolio holdings at times it deems necessary and appropriate to rating and ranking organizations; financial printers; proxy voting service providers; pricing information vendors; issuers of guaranteed investment contracts for stable value portfolios; 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 Department or Office of the General Counsel. 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 equivalent 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.; Canon Business Process Services; Charles River Systems, Inc.; Confluence Technology Inc.; Eagle Investments; Equilend; FactSet Research Systems Inc.; Gresham Technologies, Plc.; Institutional Shareholder Services, Inc.; Intellicor, LLC; Investment Technology Group, Inc.; Lipper, Inc.; Markit WSO Corporation; McMunn Associates Inc.; Morningstar, Inc.; Phoenix Lithographing Corporation; Pirium Systems Inc.; Reuters America Inc.; R.R.

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 Ethical Conduct, 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 Ethical Conduct or the Policies and Procedures Designed to Prevent the Misuse of Inside Information; (2) an investment advisor, sub-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 equivalent investments and derivatives. Disclosure of Vanguard fund complete portfolio holdings or other investment positions by Vanguard, VMC, or a Vanguard fund to Affiliates and Fiduciaries must be authorized by a Vanguard fund officer or a Principal of Vanguard.

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

Disclosure of Portfolio Holdings to Trading Counterparties in the Normal Course of Managing a Fund’s Assets

An investment advisor, sub-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 any trading counterparty, including one or more broker-dealers or banks, during the course of, or in connection with, normal day-to-day securities and derivatives transactions with or through such trading counterparties subject to the counterparty’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 trading counterparties must be authorized by a Vanguard fund officer or a Principal of Vanguard.

In addition to the disclosures described below to Authorized Participants, a Vanguard fund investment advisor or administrator may also disclose portfolio holdings information to other current or prospective fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units (as defined below) or other large transactions with a Vanguard fund. Such shareholders are typically Authorized Participants or other financial institutions that have been authorized by VMC to purchase and redeem large blocks of shares, but may also include market makers and other institutional market participants and entities to whom a Vanguard fund advisor or administrator may provide information in connection with transactions in a Vanguard fund.

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, VMC, or a Vanguard fund must be authorized by a Vanguard fund officer or a Principal of Vanguard.

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

Disclosure of Portfolio Holdings, Including Other Investment Positions, in Accordance with Securities and Exchange Commission (SEC) Exemptive Orders and Rule 6c-11

Vanguard’s ETF Operations team may disclose to the National Securities Clearing Corporation (NSCC), Authorized Participants, and other market makers the daily portfolio composition files (PCFs) that identify a basket of specified securities that may overlap with the actual or expected portfolio holdings of the Vanguard funds that offer a class of shares known as Vanguard ETF Shares (ETF Funds). Each Vanguard fund relying on Rule 6c-11 under the 1940 Act generally will seek to disclose complete portfolio holdings, including other investment positions, at the

beginning of each business day. These portfolio holdings, including other investment positions, will be disclosed online at vanguard.com. The disclosure of PCFs and portfolio holdings, including other investment positions, will be in accordance with the terms and conditions of related exemptive orders (Vanguard ETF Exemptive Orders) issued by the SEC or Rule 6c-11 under the 1940 Act, as described in this section. In addition to disclosing PCFs to the NSCC, as previously described, Vanguard’s ETF Operations team will generally disclose the PCF for any ETF Fund online at vanguard.com.

Unlike the conventional classes of shares issued by ETF Funds, the ETF Shares are listed for trading on a national securities exchange. Each ETF Fund issues and redeems ETF Shares in large blocks, known as “Creation Units.” To purchase or redeem a Creation Unit, an investor must be an “Authorized Participant” or the investor must purchase or redeem through a broker-dealer that is an Authorized Participant. An Authorized Participant is a participant in the Depository Trust Company (DTC) that has executed a “Participant Agreement” with VMC. Each ETF Fund issues Creation Units in exchange for a “portfolio deposit” consisting of a basket of specified securities (Deposit Securities) and a cash payment (Balancing Amount). Each ETF Fund also generally redeems Creation Units in kind; an investor who tenders a Creation Unit will receive, as redemption proceeds, a basket of specified securities together with a Balancing Amount.

In connection with the creation and redemption process, and in accordance with the terms and conditions of the Vanguard ETF Exemptive Orders and Rule 6c-11, Vanguard’s ETF Operations team makes available to the NSCC (a clearing agency registered with the SEC and affiliated with the DTC), for dissemination to NSCC participants on each business day prior to the opening of trading on the listing exchange, a PCF containing a list of the names and the required number of shares of each Deposit Security for each ETF Fund. In addition, the listing exchange disseminates

(1)continuously throughout the trading day, through the facilities of the Consolidated Tape Association, the market

value of an ETF Share; and (2) every 15 seconds throughout the trading day, a calculation of the estimated NAV of an ETF Share (expected to be accurate to within a few basis points). Comparing these two figures allows an investor to determine whether, and to what extent, ETF Shares are selling at a premium or at a discount to NAV. ETF Shares are listed on the exchange and traded on the secondary market in the same manner as other equity securities. The price of ETF Shares trading on the secondary market is based on a current bid/offer market.

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

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

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

Prohibitions on Receipt of Compensation or Other Consideration

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

INVESTMENT ADVISORY AND OTHER SERVICES

The Funds receive all investment advisory services from Vanguard, through its Equity Index Group. These services are provided by an experienced advisory staff employed directly by Vanguard. The compensation and other expenses of the advisory staff are allocated among the funds utilizing these services.

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore had not incurred any advisory expenses.

1. Other Accounts Managed

The following table provides information relating to the other accounts managed by the portfolio managers of the Funds as of xx, 20xx (unless otherwise noted). As of the date of this SAI,Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations.

2. Material Conflicts of Interest

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

3. Description of Compensation

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

In the case of portfolio managers responsible for managing multiple Vanguard funds or accounts, the method used to determine their compensation is the same for all funds and investment accounts. A portfolio manager’s base salary is determined by the manager’s experience and performance in the role, taking into account the ongoing compensation benchmark analyses performed by Vanguard’s Human Resources Department. A portfolio manager’s base salary is generally a fixed amount that may change as a result of an annual review, upon assumption of new duties, or 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 the fund’s investment objective, policies, strategies, and limitations, and the market environment during the measurement period. This performance factor is not based on the amount of assets held in any individual fund’s portfolio. For each Fund, the performance factor depends on how closely the portfolio manager tracks the Fund’s benchmark index 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 previously described. The bonus is paid on an annual basis.

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

4. Ownership of Securities

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations, and therefore the portfolio manager(s) did not own any shares of the Funds.

Duration and Termination of Investment Advisory Agreements

Vanguard provides 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.

Securities Lending

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore had not conducted any securities lending activities. Pursuant to Vanguard’s securities lending policy, Vanguard’s fixed income and money market funds are not permitted to, and do not, lend their investment securities.

The services provided by Brown Brothers Harriman & Co. and Vanguard, each acting separately as securities lending agents for certain Vanguard funds, include coordinating the selection of securities to be loaned to approved borrowers; negotiating the terms of the loan; monitoring the value of the securities loaned and corresponding collateral, marking to market daily; coordinating the investment of cash collateral in the funds’ approved cash collateral reinvestment vehicle; monitoring dividends and coordinating material proxy votes relating to loaned securities; and transferring, recalling, and arranging the return of loaned securities to the funds upon termination of the loan.

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 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.

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore had not incurred any brokerage commissions.

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

As of the date of this SAI, Vanguard Developed Markets ex-US Value Index ETF and Vanguard Developed Markets ex-US Growth Index ETF had not commenced operations and therefore had not held securities of its “regular brokers or dealers,” as that term is defined in Rule 10b-1 of the 1940 Act.

PROXY VOTING

I. Proxy Voting Policies

Each Vanguard fund advised by Vanguard retains the authority to vote proxies received with respect to the shares of equity securities held in a portfolio advised by Vanguard. The Board of Trustees of the Vanguard-advised funds (the Board) has adopted proxy voting procedures and guidelines to govern proxy voting for each portfolio retaining proxy voting authority, which are summarized in Appendix A.

Vanguard has entered into agreements with various state, federal, and non-U.S. regulators and with certain issuers that limit the amount of shares that the funds may vote at their discretion for particular securities. For these securities, the funds are able to vote a limited portion of the shares at their discretion. Any additional shares generally are voted in the same proportion as votes cast by the issuer’s entire shareholder base (i.e., mirror voted), or the fund is not permitted to vote such shares. Further, the Board has adopted policies that will result in certain funds mirror voting a higher proportion of the shares they own in a regulated issuer in order to permit certain other funds (generally advised by managers not affiliated with Vanguard) to mirror vote none, or a lower proportion, of their shares in such regulated issuer.

II. Securities Lending

There may be occasions when Vanguard needs to restrict lending of and/or recall securities that are out on loan in order to vote the full position at a shareholder meeting. For the funds managed by Vanguard, Vanguard has processes to monitor securities on loan and to evaluate any circumstances that may require it to restrict and/or attempt to recall the security based on the criteria set forth in Appendix A.

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

INFORMATION ABOUT THE ETF SHARE CLASS

Each Fund (collectively, the ETF Funds) offers and issues an exchange-traded class of shares called ETF Shares. Each Fund issues and redeems 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 transact through a broker that is an Authorized Participant. An Authorized Participant is a participant in the Depository Trust Company (DTC) that has executed a Participant Agreement with Vanguard Marketing Corporation, the ETF Funds’ Distributor (the Distributor). For a current list of Authorized Participants, contact the Distributor.

Investors that are not Authorized Participants must hold ETF Shares in a brokerage account. As with any stock traded on an exchange through a broker, purchases and sales of ETF Shares will be subject to usual and customary brokerage commissions.

Each ETF Fund issues Creation Units in kind in exchange for a basket of securities 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 securities that are part of the Fund’s portfolio holdings (Redemption Securities). As part of any creation or redemption transaction, the investor will either pay or receive some cash in addition to the securities (which may, in certain instances, include American Depository Receipts (ADRs)), as described more fully on the following pages. Each ETF Fund reserves the right to issue Creation Units for cash, rather than in kind.

Exchange Listing and Trading

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 (NAV). There can be no assurance that, in the future, ETF Shares will continue to meet all of the exchange’s listing requirements. The exchange will institute procedures to delist a Fund’s ETF Shares if the Fund’s ETF Shares do not continuously comply with the exchange’s listing rules. The exchange will also delist a Fund’s ETF Shares upon termination of the ETF share class.

The exchange disseminates, through the facilities of the Consolidated Tape Association, an updated “indicative optimized portfolio value” (IOPV) for an ETF Fund as calculated by an information provider. The ETF Funds are not involved with or responsible for the calculation or dissemination of the IOPVs, and they make no warranty as to the accuracy of the IOPVs. An IOPV for a Fund’s ETF Shares is disseminated every 15 seconds during regular exchange trading hours. An IOPV has a securities value component and a cash component. The IOPV is designed as an estimate of an ETF Fund’s NAV at a particular point in time, but it is only an estimate and should not be viewed as the actual NAV, which is calculated once each day.

Book Entry Only System

ETF Shares issued by the ETF Funds are registered in the name of the DTC or its nominee, Cede & Co., and are 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 (DTC Participants) and to facilitate the clearance and settlement of transactions among them through electronic book-entry changes in their accounts, 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 (DTCC), which is owned by certain participants of the 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 (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. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities. Such laws may impair the ability of certain investors to acquire beneficial interests in 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.

Conveyance of all notices, statements, and other communications to Beneficial Owners is effected as follows. The DTC will make available to an ETF Fund, upon request and for a fee, a listing of the ETF Shares of the Fund held by each DTC Participant. The ETF Fund shall obtain from each DTC Participant the number of Beneficial Owners holding ETF Shares, directly or indirectly, through the DTC Participant. The ETF Fund shall provide each DTC Participant with copies of such notice, statement, or other communication, in form, in number, and at such place as the DTC Participant may reasonably request, in order that these communications may be transmitted by the DTC Participant, directly or indirectly, to the Beneficial Owners. In addition, the ETF Fund shall pay to each DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, 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 immediately credit the DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in ETF Shares of the appropriate ETF 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 ETF Funds have no responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners; for payments made on account of beneficial ownership interests in such ETF Shares; for maintenance, supervision, or review of any records relating to such beneficial ownership interests; or for any other aspect of the relationship between the DTC and 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 ETF Funds and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the ETF Funds 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 ETF Funds make other arrangements with respect thereto satisfactory to the exchange.

Purchase and Issuance of ETF Shares in Creation Units

Except for conversions to ETF Shares from 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 its NAV next determined after receipt of an order in proper form on any business day. The ETF Funds do not issue fractional Creation Units. (Please see “Conversions and Exchanges” for the issuance of ETF Shares resulting from a conversion.)

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 U.S. holidays: New Year’s Day; Martin Luther King, Jr., Day; Presidents’ Day (Washington’s Birthday); Good Friday; Memorial Day; Juneteenth National Independence Day; 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 an in-kind deposit of a designated portfolio of securities (Deposit Securities) and an amount of cash (Cash Component) consisting of a purchase balancing amount and a transaction fee (both described in the following paragraphs). Together, the Deposit Securities and the Cash Component constitute the fund deposit.

The purchase balancing amount is an amount equal to the difference between the NAV of a Creation Unit and the market value of the Deposit Securities (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 purchase 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 an ETF Fund in cash. If the purchase 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 an ETF Fund to the purchaser in cash (except as offset by the transaction fee).

Vanguard, through the National Securities Clearing Corporation (NSCC), makes available after the close of each business day a list of the names and the number of shares of each Deposit Security to be included in the next business day’s fund deposit for each ETF Fund (subject to possible amendment or correction). 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, to reflect interest payments on underlying bonds, or to respond to adjustments to the weighting or composition of the component securities of the relevant target index.

Each ETF Fund reserves the right to permit or require the substitution of an amount of cash—referred to as “cash in lieu”—to be added to the Cash Component to replace any Deposit Security. This might occur, for example, if a Deposit Security is not available in sufficient quantity for delivery, is not eligible for transfer through the applicable clearance and settlement system, or is not eligible for trading by an Authorized Participant or the investor for which an Authorized Participant is acting. Trading costs incurred by the ETF Fund in connection with the purchase of Deposit Securities with cash-in-lieu amounts will be an expense of the ETF Fund. However, Vanguard may adjust the transaction fee 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 ETF Fund, and the ETF Fund’s determination shall be final and binding.

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

For all ETF Funds, to initiate a purchase order for a Creation Unit (either through the Clearing Process or outside the Clearing Process for stock ETF Funds), an Authorized Participant must submit an order in proper form to the Distributor and such order must be received by the Distributor prior to the closing time of regular trading 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. Authorized Participants must transmit orders using a transmission method acceptable to the Distributor pursuant to procedures set forth in the Participant 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 Funds, 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 or email systems were not operating properly).

If you are not an Authorized Participant, you must place your purchase order in an acceptable form with an Authorized Participant. 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).

Placement of Purchase Orders. An Authorized Participant must deliver the cash and government securities portion of a fund deposit through the Federal Reserve’s Fedwire System and the corporate securities portion of a fund deposit through the DTC. If a fund deposit is incomplete on the first business day after the trade date (the trade date, known as “T,” is the date on which the trade actually takes place; one business day after the trade date is known as “T+1”) because of the failed delivery of one or more of the Deposit Securities, the Fund shall be entitled to cancel the purchase order.

Each Fund may issue Creation Units in reliance on the Authorized Participant’s undertaking to deliver the missing Deposit Securities at a later date. Such undertaking shall be secured by the delivery and maintenance of cash collateral in an amount determined by the Fund in accordance with the terms of the Participant Agreement.

Rejection of Purchase Orders. An ETF Fund reserves the absolute right to reject a purchase order. By way of example, and not limitation, an ETF Fund will reject a purchase order if:

■The order is not in proper form.

■The Deposit Securities delivered are not the same (in name or amount) as the published basket.

■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, at the discretion of the ETF Fund or Vanguard, have an adverse effect on the Fund or any of its shareholders.

■Circumstances outside the control of the ETF Fund, the Trust, the transfer agent, the custodian, the Distributor, and Vanguard make it for all practical purposes impossible to process the order. Examples include, but are not limited to, 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 aforementioned parties as well as the DTC, the NSCC, the Federal Reserve, or any other participant in the purchase process; and similar extraordinary events.

If a purchase order is rejected, the Distributor shall notify the Authorized Participant that submitted the order. The ETF Funds, the Trust, the transfer agent, the custodian, the Distributor, and Vanguard 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. An ETF Fund may impose a transaction fee (payable to the Fund) to compensate the ETF Fund for costs associated with the issuance of Creation Units. The amount of the fee, which may be changed by an ETF Fund from time to time at its sole discretion, is made available daily to Authorized Participants, market makers, and other interested parties through Vanguard’s proprietary portal system. For all ETF Funds except Vanguard Extended Duration Treasury Index Fund, an additional charge may be imposed for purchases of Creation Units effected outside the Clearing Process. When an ETF Fund permits (or requires) a purchaser to substitute cash in lieu of depositing one or more Deposit Securities, the purchaser may be assessed an additional variable charge on the cash-in-lieu portion of the investment. The amount of this charge will be disclosed to investors before they place their orders. The amount will be determined by the ETF Fund at its sole discretion. The maximum transaction fee, including any variable charges, on purchases of Creation Units, including any additional charges as described, shall be 2% of the value of the Creation Units.

An ETF Fund reserves the right to not impose a transaction fee or to vary the amount of the transaction fee imposed, up to the maximum amount listed above. To the extent a creation transaction fee is not charged or does not cover the costs associated with the issuance of the Creation Units, certain costs may be borne by the ETF Fund.

Redemption of ETF Shares in Creation Units

To be eligible to place a redemption order, you must be an Authorized Participant. Investors that are not Authorized Participants must make appropriate arrangements with an Authorized Participant in order to redeem a Creation Unit.

ETF Shares may be redeemed only in Creation Units. Investors should expect to incur brokerage and other transaction 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 received on a business day in good order will receive the NAV next determined after the request is made.

Unless cash redemptions are available or specified for an ETF Fund, an investor tendering a Creation Unit generally will receive redemption proceeds consisting of (1) a basket of Redemption Securities; plus (2) a redemption balancing amount in cash 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 transaction fee. If the Redemption Securities have a value greater than the NAV of a Creation Unit, the redeeming investor will pay the redemption balancing amount in cash to the ETF Fund, rather than receive 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 for an ETF Fund

(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 an investor purchasing a Creation Unit. An ETF Fund may provide a redeeming investor with a basket of Redemption Securities that differs from the composition of the redemption basket published through the NSCC.

An 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 previously discussed, or if the ETF 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 Funds, 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 or email systems were not operating properly).

Transaction Fee on Redemptions of Creation Units. An ETF Fund may impose a transaction fee (payable to the Fund) to compensate the ETF Fund for costs associated with the redemption of Creation Units. The amount of the fee, which may be changed by an ETF Fund from time to time at its sole discretion, is made available daily to Authorized Participants, market makers, and other interested parties through Vanguard’s proprietary portal system. For all ETF Funds except Vanguard Extended Duration Treasury Index Fund, an additional charge may be imposed for redemptions of Creation Units effected outside the Clearing Process. When an ETF Fund permits (or requires) a redeeming investor to receive cash in lieu of one or more Redemption Securities, each ETF Fund may assess an additional variable charge on the cash portion of the redemption. The amount will vary as determined by the ETF Fund at its sole discretion and is made available daily to Authorized Participants, market makers, and other interested parties through Vanguard’s proprietary portal system. The maximum transaction fee, including any variable charges, on redemptions of Creation Units shall be 2% of the value of the Creation Units.

An ETF Fund reserves the right to not impose a transaction fee or to vary the amount of the transaction fee imposed, up to the maximum amount listed above. To the extent a redemption transaction fee is not charged or does not cover the costs associated with the redemption of the Creation Units, certain costs may be borne by an ETF Fund.

Placement of Redemption Orders. To initiate a redemption order for a Creation Unit, an Authorized Participant must submit such order in proper form to the Distributor before Closing Time in order to receive that day’s NAV. Authorized Participants must transmit orders using a transmission method acceptable to the Distributor pursuant to procedures set forth in the Participant Agreement.

If on the settlement date (typically T+1) an Authorized Participant has failed to deliver all of the Vanguard ETF Shares it is seeking to redeem, the ETF Fund shall be entitled to cancel the redemption order. Alternatively, the ETF Fund may deliver to the Authorized Participant the full complement of Redemption Securities and cash in reliance on the Authorized Participant’s undertaking to deliver the missing ETF Shares at a later date. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of cash collateral in accordance with collateral procedures that are part of the Participant Agreement. In all cases the ETF Fund shall be entitled to charge the Authorized Participant for any costs (including investment losses, attorney’s fees, and interest) incurred by the ETF Fund as a result of the late delivery or failure to deliver.

If an Authorized Participant, or a redeeming investor acting through an Authorized Participant, is subject to a legal restriction with respect to a particular security included in the basket of Redemption Securities, such investor may be paid an equivalent amount of cash in lieu of the security. 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.

As a result of security settlement cycles, local market holidays, and unscheduled foreign market closings, ETFs that hold foreign investments may deliver redemption proceeds (either in kind or in cash) more than seven days (but no more than fifteen days) after receipt of a redemption request in proper form.

Suspension of Redemption Rights. The right of redemption may be suspended or the date of payment postponed with respect to an ETF Fund (1) for any period during which the NYSE or listing exchange is closed (other than customary weekend and holiday closings), (2) for any period during which trading on the NYSE or listing exchange is suspended or restricted, (3) for any period during which an emergency exists as a result of which disposal of the Fund’s portfolio securities or determination of its NAV is not reasonably practicable, or (4) in such other circumstances as the SEC permits.

Precautionary Notes

A precautionary note to ETF investors: The DTC or its nominee will be the registered owner of all outstanding ETF Shares. Your ownership of ETF Shares will be shown on the records of the DTC and the DTC Participant 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.

You should also be aware that investments in ETF Shares may be subject to certain risks relating to having large shareholders. To the extent that a large number of the Fund’s ETF Shares are held by a large shareholder (e.g., an institutional investor, an investment advisor or an affiliate of an investment advisor, an authorized participant, a lead market maker, or another entity), a large redemption by such a shareholder could result in an increase in the ETF’s expense ratio, cause the ETF to incur higher transaction costs, cause the ETF to fail to comply with applicable listing standards of the listing exchange upon which it is listed, lead to the realization of taxable capital gains, or cause the remaining shareholders to receive distributions representing a disproportionate share of the ETF’s ordinary income and long-term capital gains. In addition, transactions by large shareholders may account for a large percentage of the trading volume on an exchange and may, therefore, have a material upward or downward effect on the market price of the ETF Shares.

A precautionary note to purchasers of Creation Units: You should be aware of certain legal risks unique to investors purchasing Creation Units directly from the issuing fund.

Because new ETF Shares may be issued on an ongoing basis, a “distribution” of ETF Shares could be occurring at any time. Certain activities that you perform as a dealer could, depending on the circumstances, result in your being deemed a participant in the distribution in a manner that could render you a statutory underwriter and subject you to the prospectus delivery and liability provisions of the Securities Act of 1933 (the 1933 Act). For example, you could be deemed a statutory underwriter if you purchase Creation Units from the issuing fund, break them down into the constituent ETF Shares, and sell those shares directly to customers or if you choose to couple the creation of a supply of new ETF Shares with an active selling effort involving solicitation of secondary market demand for ETF Shares. Whether a person is an underwriter depends upon all of the facts and circumstances pertaining to that person’s activities, and the examples mentioned here should not be considered a complete description of all the activities that could cause you to be deemed an underwriter.

Dealers who are not “underwriters” but are participating in a distribution (as opposed to engaging in ordinary secondary-market transactions), and thus dealing with ETF Shares as part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act.

A precautionary note to shareholders redeeming Creation Units: An Authorized Participant that is not a “qualified institutional buyer” as defined in Rule 144A under the 1933 Act will not be able to receive, as part of the redemption basket, restricted securities eligible for resale under Rule 144A.

A precautionary note to investment companies: Vanguard ETF Shares are issued by registered investment companies, and therefore the acquisition of such shares by other investment companies and private funds is subject to the restrictions of Section 12(d)(1) of the 1940 Act. SEC Rule 12d1-4 under the 1940 Act permits investments in Vanguard ETF Shares beyond the limits of Section 12(d)(1), subject to the conditions of Rule 12d1-4, as described under the heading “Other Investment Companies.”

APPENDIX A

Summary of the Vanguard-Advised Funds Proxy Voting Policy

The funds for which Vanguard acts as investment advisor (Vanguard-advised funds) retain authority to vote proxies received for the shares of equity securities held in each fund. The Board of Trustees (the Board) for the Vanguard-advised funds has adopted proxy voting procedures and guidelines to govern proxy voting for each portfolio retaining proxy voting authority.

The Investment Stewardship Oversight Committee (the Committee), comprised primarily of fund officers and subject to the procedures described below, oversees the Vanguard-advised funds’ proxy voting. The Committee reports directly to the Board. Vanguard is subject to these procedures and the proxy voting policies to the extent that they call for Vanguard to administer the voting process and implement the resulting voting decisions, and for these purposes the voting policies have also been approved by the Board of Directors of Vanguard.

The voting principles and policies adopted by the Board provide a framework for assessing each proposal and seek to ensure that each vote is cast in the best interests of each fund. Under the voting policies, each proposal is evaluated on its merits, based on the particular facts and circumstances presented at the company in question. For more information on the funds’ proxy voting policies, please visit about.vanguard.com/investment-stewardship.

I. Investment Stewardship Team

The Investment Stewardship Team administers the day-to-day operation of the funds’ proxy voting process, overseen by the Committee. The Investment Stewardship Team performs the following functions: (1) managing and conducting due diligence of proxy voting vendors; (2) reconciling share positions; (3) analyzing proxy proposals using factors described in the voting policies; (4) determining and addressing potential or actual conflicts of interest that may be presented by a particular proxy; and (5) voting proxies. The Investment Stewardship Team also prepares periodic and special reports for the Board and proposes amendments to the procedures and voting policies.

II. Investment Stewardship Oversight Committee

The Board, including a majority of the independent trustees, appoints the members of the Committee (which is comprised primarily of fund officers). The Committee works with the Investment Stewardship Team to provide reports and other guidance to the Board regarding proxy voting by the funds. The Committee has an obligation to exercise its decision-making authority in accordance with the Board’s instructions as set forth in the funds’ proxy voting procedures and voting policies and subject to the fiduciary standards of good faith, fairness, and Vanguard’s Code of Ethical Conduct. The Committee may advise the Investment Stewardship Team on how to best apply the Board’s instructions as set forth in the voting policies or refer the matter to the Board, which has ultimate decision-making authority for the funds. The Board reviews the procedures and voting policies annually and modifies them from time to time upon the recommendation of the Committee and in consultation with the Investment Stewardship Team.

III. Proxy Voting Pillars

Vanguard’s investment stewardship activities are grounded in four pillars of corporate governance:

1)Board composition and effectiveness: Good governance begins with a company’s board of directors. Our primary focus is on understanding to what extent the individuals who serve as board members are appropriately independent, capable, and experienced.

2)Board oversight of strategy and risk: Boards should be meaningfully involved in the formation and oversight of strategy and have ongoing oversight of material risks to their company. We work to understand how boards of directors are involved in strategy formation, oversee company strategy, and identify and govern material risks to long-term shareholder returns.

3)Executive pay (compensation or remuneration): Sound, performance-linked compensation programs drive long-term investment returns. We look for companies to provide clear disclosure about their compensation practices, the board’s oversight of those practices, and how said practices are aligned with long-term shareholder returns.

4)Shareholder rights: We believe governance structures should allow shareholders to effectively exercise their foundational rights. Shareholder rights enable a company’s owners to use their voice and their vote—ideally, consistent with their economic exposure—to effect and approve changes in corporate governance practices.

IV. Evaluation of Proxies

For ease of reference, the procedures and guidelines often refer to all Vanguard-advised funds. However, the processes and practices seek to ensure that proxy voting decisions are suitable for individual funds. For most proxy proposals, particularly those involving routine corporate governance matters, the evaluation could result in the funds having a common interest in the matter and, accordingly, each fund casting votes in the same manner. In other cases, however, a fund may vote differently from other funds, depending upon the nature and objective of each fund, if doing so is in the best interest of the individual fund.

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

In evaluating proxy proposals, the Investment Stewardship Team considers information from many sources, which could include, but is not limited to, the perspectives of the company management or shareholders presenting a proposal, independent proxy research services, or proprietary research. Additionally, data and recommendations from proxy advisors serve as one of many inputs into our research process. The Vanguard-advised funds may utilize automated voting for matters that are clearly addressed by the funds’ proxy voting procedures and guidelines.

While serving as a framework, the voting policies 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 Investment Stewardship Team, under the supervision of the Committee, will evaluate the matter and cast the fund’s vote in a manner that is in the fund’s best interest, subject to the individual circumstances of the fund.

V. Conflicts of Interest

Vanguard takes seriously its commitment to avoid potential conflicts of interest. Vanguard funds invest in thousands of publicly listed companies worldwide. Those companies may include clients, potential clients, vendors, or competitors. Some companies may employ Vanguard trustees, former Vanguard executives, or family members of Vanguard personnel who have direct involvement in Vanguard’s Investment Stewardship program.

Vanguard’s approach to mitigating conflicts of interest begins with the funds’ proxy voting procedures. The procedures require that voting personnel act as fiduciaries and must conduct their activities at all times in accordance with the following standards: (i) fund shareholders’ interests come first; (ii) conflicts of interest must be avoided and mitigated to the extent possible; and (iii) compromising situations must be avoided.

We maintain an important separation between Vanguard’s Investment Stewardship Team and other groups within Vanguard that are responsible for sales, marketing, client service, and vendor/partner relationships. Proxy voting personnel are required to disclose potential conflicts of interest and must recuse themselves from all voting decisions and engagement activities in such instances. In certain circumstances, Vanguard may refrain from voting shares of a company, or may engage an independent third-party fiduciary to vote proxies.

Each externally managed fund has adopted the proxy voting guidelines of its advisor(s) and votes in accordance with the external advisors’ guidelines and procedures. Each advisor has its own procedures for managing conflicts of interest in the best interests of fund shareholders.

VI. Shareholder Proposals

Shareholder proposals are evaluated in the context of the general corporate governance principle that a company’s board has ultimate responsibility for providing effective ongoing oversight of relevant sector and company-specific risks, including risks related to environmental and social matters. Each proposal is evaluated on its merits and in the context of the particular facts and circumstances at the company in question and supported when there is a logically demonstrable linkage between the specific proposal and long-term shareholder value of the company. Some of the factors considered when evaluating shareholder proposals include the materiality of the risk addressed by the proposal, the quality of the current disclosures/business practices, and any progress by the company toward addressing and disclosing the relevant material risk.

VII. Voting in Markets Outside the United States

Corporate governance standards, disclosure requirements, and voting mechanics vary greatly among the markets outside the United States (U.S.) in which the funds may invest. Each fund’s votes will be used, where applicable, to support improvements in governance and disclosure by each fund’s portfolio companies. Matters presented by non-U.S. portfolio companies will be evaluated in the foregoing context, as well as in accordance with local market standards and best practices. Votes are cast for each fund in a manner philosophically consistent with the voting policies, taking into account differing practices by market.

In many other markets, voting proxies will result in a fund being prohibited from selling the shares for a period of time due to requirements known as “share-blocking” or reregistration. Generally, the value of voting is unlikely to outweigh the loss of liquidity imposed by these requirements on the funds. In such instances, the funds will generally abstain from voting.

The costs of voting (e.g., custodian fees, vote agency fees) in other 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.

VIII. Voting Shares of a Company That Has an Ownership Limitation

Certain companies have provisions in their governing documents or other agreements that restrict stock ownership in excess of a specified limit. Typically, these ownership restrictions are included in the governing documents of real estate investment trusts but may be included in other companies’ governing documents. A company’s governing documents normally allow the company to grant a waiver of these ownership limits, which would allow a fund to exceed the stated ownership limit. Sometimes a company will grant a waiver without restriction. From time to time, a company may grant a waiver only if a fund (or funds) agrees to not vote the company’s shares in excess of the normal specified limit. In such a circumstance, a fund may refrain from voting shares if owning the shares beyond the company’s specified limit is in the best interests of the fund and its shareholders.

In addition, applicable law may require prior regulatory approval to permit ownership of certain regulated issuer’s voting securities above certain limits or may impose other restrictions on owners of more than a certain percentage of a regulated issuer’s voting shares. The Board has authorized the funds to vote shares above these limits in the same

proportion as votes cast by the issuer’s entire shareholder base (i.e., mirror vote), or to refrain from voting excess shares. Further, the Board has adopted policies that will result in certain funds mirror voting a higher proportion of the shares they own in a regulated issuer in order to permit certain other funds (generally advised by managers not affiliated with Vanguard) to mirror vote none, or a lower proportion of, their shares in such regulated issuer.

IX. 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.

X. Securities Lending

There may be occasions when Vanguard needs to restrict lending of and/or recall securities that are out on loan in order to vote in a shareholder meeting. Vanguard has processes to monitor securities on loan and to evaluate any circumstances that may require us to restrict and/or recall the stock. In making this decision, we consider:

■The subject of the vote and whether, based on our knowledge and experience, we believe the topic is potentially material to the corporate governance and/or long-term performance of the company;

■The funds’ individual and/or aggregate equity investment in a company, and whether we estimate that voting funds’ shares would affect the shareholder meeting outcome; and

■The long-term impact to our fund shareholders, evaluating whether we believe the benefits of voting a company’s shares would outweigh the benefits of stock lending revenues in a particular instance.
