The fund issues and redeems shares at its NAV only in large blocks of shares (Creation Units). These transactions are usually in

exchange for a basket of securities included in the index and/or an amount of cash. As a practical matter, only Authorized Participants purchase or redeem Creation Units.

Individual shares may only be purchased and sold in the secondary market (i.e., on a national securities exchange) through a broker or dealer at market prices. Because fund shares trade at market prices rather than at NAV, fund shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) (the “bid-ask spread”). Recent information regarding the fund’s NAV, market price, premiums and discounts, and bid-ask spreads is available at www.schwabassetmanagement.com.

Dividends and capital gains distributions received from the fund will generally be taxable as ordinary income or capital gains, unless you are investing through an IRA, 401(k) or other tax-advantaged account (in which case you may be taxed later, upon withdrawal of your investment from such account).

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the adviser and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

The funds described in this prospectus are advised by Charles Schwab Investment Management, Inc., dba Schwab Asset Management. Each fund is an “exchange-traded fund” (ETF). ETFs are funds that trade like other publicly-traded securities.

The funds in this prospectus are index funds and share the same basic investment strategy: each of the funds tracks a RAFI^™ Fundamental High Liquidity Index which is based on the “Fundamental Index” methodology. This strategy distinguishes an index fund from an “actively managed” fund. Instead of choosing investments for the fund based on portfolio management’s judgment, an index is used to determine which securities the fund should own.

In contrast to most equity indices, which generally are based on market capitalization, the RAFI Fundamental High Liquidity Index Series selects and weights stocks according to fundamental measures of company size: adjusted sales, retained operating cash flow, and dividends plus buybacks. The RAFI Fundamental High Liquidity Index Series determines constituent weights annually in March. The weights are then implemented using a quarterly reconstitution methodology that rebalances four equal segments on a rolling quarterly basis.

Because the composition of an index tends to be comparatively stable, most index funds historically have shown low portfolio turnover compared to actively managed funds.

Unlike shares of a mutual fund, shares of the funds are listed on a national securities exchange and trade at market prices that change

throughout the day. The market price for each of the fund’s shares may be different from its net asset value per share or NAV. The funds

have their own CUSIP numbers and trade on the NYSE Arca, Inc. under the following tickers:

Each fund issues and redeems shares at its NAV only in large blocks of shares (Creation Units). These transactions are usually in exchange for a basket of securities and/or an amount of cash. As a practical matter, only institutional investors who have entered into an authorized participant agreement (Authorized Participants) purchase or redeem Creation Units.

A Note to Retail Investors

Shares can be purchased directly from the funds only in exchange for a basket of securities and/or an amount of cash that is expected to be worth a minimum of a million dollars or more. Most individual investors, therefore, will not be able to purchase shares directly from the funds. Instead, these investors will purchase shares in the secondary market through a brokerage account or with the assistance of a broker. Thus, some of the information contained in this prospectus – such as information about purchasing and redeeming shares from the funds and references to transaction fees imposed on purchases and redemptions – is not relevant to most individual investors. Shares purchased or sold through a brokerage account or with the assistance of a broker may be subject to brokerage commissions and charges.

Each fund’s performance will fluctuate over time and, as with all investments, future performance may differ from past performance.

There can be no assurance that a fund will achieve its investment objective. Except as explicitly described otherwise, the investment objectives, strategies, and policies of each fund may be changed without shareholder approval.

The principal investment strategies and the main risks associated with investing in each fund are summarized in the fund summaries at the front of this prospectus. This section takes a more detailed look at some of the types of securities, the associated risks, and the various investment strategies that may be used in the day-to-day portfolio management of the funds, as described below. In addition to the particular types of securities and strategies that are described in this prospectus, each fund may use strategies that are not described herein in support of its overall investment goal. These additional strategies and the risks associated with them are described in the “Investment Objectives, Strategies, Risks and Limitations” section in the Statement of Additional Information (SAI).

Schwab Fundamental U.S. Broad Market ETF

Investment Objective

The fund’s goal is to track as closely as possible, before fees and expenses, the total return of an index that measures the performance of U.S. based companies based on their fundamental size and weight. The fund’s investment objective is not fundamental and therefore may be changed by the fund’s Board of Trustees without shareholder approval.

Index

As of February 28, 2026, the RAFI Fundamental High Liquidity US All Index consisted of 1,606 constituent companies which had an average market capitalization of $569 billion (the market capitalization of the constituent companies ranged from $8 million to $4.3 trillion). The index is owned by RAFI Indices, LLC, a wholly owned subsidiary of Research Affiliates Global Holdings, LLC.

More Information About Principal Investment Risks

The fund is subject to risks, any of which could cause an investor to lose money.

Market Risk — Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs, and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and the fund’s investments. As with any investment whose performance is tied to financial markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Style Risk — The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market, even though these securities may go in and out of favor based on market and economic conditions. The index does not weigh securities on the basis of investor protection, limitations or differences in the quality of financial reporting or other oversight mechanisms. Therefore, the fund will follow the securities in the index without consideration of these factors. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index.

At times the segment of the markets represented by the index may underperform other market segments. A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. Because of the way the index is composed, the index may perform differently or worse than an index that is based solely on market capitalization.

Index-Related Risk — The index provider does not provide any warranty as to the timeliness, accuracy or completeness of any data relating to the index. Errors relating to the index, including index data, computations and/or construction, may occur from time to time and may not be identified by the index provider for a period of time or at all. Losses resulting from index errors may be borne by the fund and its

shareholders. In addition, there can be no guarantee that the index will operate as intended during volatile market conditions or over the course of a full market cycle.

In addition, market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities markets as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Large-Cap Company Risk — Large-cap companies are generally more mature than smaller companies. They also may have fewer new market opportunities for their products or services, may focus resources on maintaining their market share, and may be unable to respond quickly to new competitive challenges. As a result, the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

Mid-Cap Company Risk — Mid-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by large-cap companies. The value of securities issued by mid-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns

Small-Cap Company Risk — Small-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by larger companies. The value of securities issued by small-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns. In addition, small-cap companies may have limited financial resources, management experience, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. Further, small-cap companies may have less publicly available information and such information may be inaccurate or incomplete.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in the index, match the securities’ weighting to the index, or the fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. The fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the fund may value individual securities based on fair value prices developed using methods approved by the fund’s Board of Trustees. To the extent the fund calculates its net asset value (NAV) based on fair value prices, the fund’s performance may diverge from that of its index. In addition, cash flows into and out of the fund, timing variances, operating expenses and trading costs all affect the ability of the fund to match the performance of the index, because the index does not have to manage cash flows and does not incur any costs. Lastly, differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index impact correlation between the performance of the fund and that of its index.

Derivatives Risk — The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. The fund’s use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain of these risks, such as liquidity risk, leverage risk, and market risk, are discussed elsewhere in this prospectus. The fund’s use of derivatives is also subject to counterparty risk, lack of availability risk, valuation risk, correlation risk, tax risk, and operational risk. Counterparty risk is the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations either because the financial condition of the counterparty declines, or because the counterparty is otherwise unable or unwilling to perform under the contract. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gains. Operational risk is the risk related to operational issues, including documentation issues, settlement issues, systems failures, inadequate controls, and human error. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. The fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that the fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

Liquidity Risk — Liquidity risk exists when particular investments may be difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities which means even a small amount of leverage can have a disproportionately large impact on the fund. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Securities Lending Risk — The fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares. Trading of shares of the fund on a national securities exchange may be halted if exchange officials deem such action appropriate, if the fund is delisted, or if the activation of marketwide “circuit breakers” halts stock trading generally. If the fund’s shares are delisted, the fund may seek to list its shares on another market, merge with another ETF, or redeem its shares at NAV.

Shares of the Fund May Trade at Prices Other Than NAV — As with all ETFs, fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s NAV, there may be times when the market price and the NAV vary significantly. Thus, an investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The investment adviser cannot predict whether shares will trade above (premium), below (discount) or at NAV. The fund may have a limited number of financial institutions that may act as “Authorized Participants” or market makers. Only Authorized Participants who have entered into agreements with the fund’s distributor may engage in creation or redemption transactions directly with the fund (as discussed in the “Creation and Redemption” section below). If those Authorized Participants exit the business or are unable to process creation and/or redemption orders (including in situations where Authorized Participants have limited or diminished access to capital required to post collateral), and no other Authorized Participant is able to step forward to create and redeem in either of these cases, fund shares may trade at a premium or discount to NAV like closed-end fund shares (and may even face delisting). Similar effects may result if market makers exit the business or are unable to continue making markets in the fund’s shares. Risks associated with having a limited number of Authorized Participants may be heightened for ETFs that invest in securities issued by non-U.S. issuers or other instruments that have lower trading volumes. More generally, market makers are not obligated to make a market in the fund’s shares, and Authorized Participants are not obligated to submit purchase or redemption orders for Creation Units. Further, while the creation/redemption feature is designed to make it likely that shares normally will trade close to the value of the fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, may result in market prices that

differ significantly from the value of the fund’s holdings. In addition, transactions by large shareholders may account for a large percentage of trading volume on the fund’s primary listing exchange and may, therefore, have a material effect on the market price of the fund’s shares.

The market price of fund shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade the fund shares. The bid/ask spread on ETF shares varies over time based on the fund’s trading volume and market liquidity. As a result, the bid/ask spread on ETF shares is generally larger when the shares have little trading volume or market liquidity and generally lower when the shares have high trading volume or market liquidity. In addition, in times of severe market disruption, the bid/ask spread can increase significantly. At those times, fund shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that investors most want to sell shares. The investment adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities. There are various methods by which investors can purchase and sell shares of the fund and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the fund.

More Information About Principal Investment Risks

The fund is subject to risks, any of which could cause an investor to lose money.

Market Risk — Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs, and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and the fund’s investments. As with any investment whose performance is tied to financial markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Style Risk — The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market, even though these securities may go in and out of favor based on market and economic conditions. The index does not weigh securities on the basis of investor protection, limitations or differences in the quality of financial reporting or other oversight mechanisms. Therefore, the fund will follow the securities in the index without consideration of these factors. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index.

At times the segment of the markets represented by the index may underperform other market segments. A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. Because of the way the index is composed, the index may perform differently or worse than an index that is based solely on market capitalization.

Index-Related Risk — The index provider does not provide any warranty as to the timeliness, accuracy or completeness of any data relating to the index. Errors relating to the index, including index data, computations and/or construction, may occur from time to time and may not be identified by the index provider for a period of time or at all. Losses resulting from index errors may be borne by the fund and its shareholders. In addition, there can be no guarantee that the index will operate as intended during volatile market conditions or over the course of a full market cycle.

In addition, market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities markets as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Large-Cap Company Risk — Large-cap companies are generally more mature than smaller companies. They also may have fewer new market opportunities for their products or services, may focus resources on maintaining their market share, and may be unable to respond quickly to new competitive challenges. As a result, the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in the index, match the securities’ weighting to the index, or the fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. The fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the fund may value individual securities based on fair value prices developed using methods approved by the fund’s Board of Trustees. To the extent the fund calculates its net asset value (NAV) based on fair value prices, the fund’s performance may diverge from that of its index. In addition, cash flows into and out of the fund, timing variances, operating expenses and trading costs all affect the ability of the fund to match the performance of the index, because the index does not have to manage cash flows and does not incur any costs. Lastly, differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index impact correlation between the performance of the fund and that of its index.

Derivatives Risk — The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. The fund’s use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain of these risks, such as liquidity risk, leverage risk, and market risk, are discussed elsewhere in this prospectus. The fund’s use of derivatives is also subject to counterparty risk, lack of availability risk, valuation risk, correlation risk, tax risk, and operational risk. Counterparty risk is the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations either because the financial condition of the counterparty declines, or because the counterparty is otherwise unable or unwilling to perform under the contract. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gains. Operational risk is the risk related to operational issues, including documentation issues, settlement issues, systems failures, inadequate controls, and human error. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. The fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that the fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

Liquidity Risk — Liquidity risk exists when particular investments may be difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities which means even a small amount of leverage can have a disproportionately large impact on the fund. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Securities Lending Risk — The fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares. Trading of shares of the fund on a national securities exchange may be halted if exchange officials deem such action appropriate, if the fund is delisted, or if the activation of marketwide “circuit breakers” halts stock trading generally. If the fund’s shares are delisted, the fund may seek to list its shares on another market, merge with another ETF, or redeem its shares at NAV.

Shares of the Fund May Trade at Prices Other Than NAV — As with all ETFs, fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s NAV, there may be times when the market price and the NAV vary significantly. Thus, an investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The investment adviser cannot predict whether shares will trade above (premium), below (discount) or at NAV. The fund may have a limited number of financial institutions that may act as “Authorized Participants” or market makers. Only Authorized Participants who have entered into agreements with the fund’s distributor may engage in creation or redemption transactions directly with the fund (as discussed in the “Creation and Redemption” section below). If those Authorized Participants exit the business or are unable to process creation and/or redemption orders (including in situations where Authorized Participants have limited or diminished access to capital required to post collateral), and no other Authorized Participant is able to step forward to create and redeem in either of these cases, fund shares may trade at a premium or discount to NAV like closed-end fund shares (and may even face delisting). Similar effects may result if market makers exit the business or are unable to continue making markets in the fund’s shares. Risks associated with having a limited number of Authorized Participants may be heightened for ETFs that invest in securities issued by non-U.S. issuers or other instruments that have lower trading volumes. More generally, market makers are not obligated to make a market in the fund’s shares, and Authorized Participants are not obligated to submit purchase or redemption orders for Creation Units. Further, while the creation/redemption feature is designed to make it likely that shares normally will trade close to the value of the fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the fund’s holdings. In addition, transactions by large shareholders may account for a large percentage of trading volume on the fund’s primary listing exchange and may, therefore, have a material effect on the market price of the fund’s shares.

The market price of fund shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade the fund shares. The bid/ask spread on ETF shares varies over time based on the fund’s trading volume and market liquidity. As a result, the bid/ask spread on ETF shares is generally larger when the shares have little trading volume or market liquidity and generally lower when the shares have high trading volume or market liquidity. In addition, in times of severe market disruption, the bid/ask spread can increase significantly. At those times, fund shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that investors most want to sell shares. The investment adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities. There are various methods by which investors can purchase and sell shares of the fund and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the fund.

In addition, market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities markets as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid-

and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Small-Cap Company Risk — Small-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by larger companies. The value of securities issued by small-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns. In addition, small-cap companies may have limited financial resources, management experience, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. Further, small-cap companies may have less publicly available information and such information may be inaccurate or incomplete.

Real Estate Investment Trusts (REITs) Risk — Although the fund does not invest directly in real estate, due to the composition of the index, the fund may have exposure to securities of REITs. Equity REITs may be affected by changes in the value of the underlying properties owned by the trusts. Further, REITs are dependent upon specialized management skills and may have their investments in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. The value of a REIT will also rise and fall in response to the creditworthiness of the issuer. In particular, the value of these securities may be affected by changes in interest rates. In addition, REITs could possibly fail to qualify for tax free pass-through of income under the Internal Revenue Code of 1986, as amended, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended. The failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses. Further, dividends paid by REITs are taxed as ordinary income and generally do not qualify for the preferential rate applicable to qualified dividend income. REITs may be more volatile and/or more illiquid than other types of securities.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant.

The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid-

and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Large-Cap Company Risk — Large-cap companies are generally more mature than smaller companies. They also may have fewer new market opportunities for their products or services, may focus resources on maintaining their market share, and may be unable to respond quickly to new competitive challenges. As a result, the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

Foreign Investment Risk — The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the U.S. These risks may negatively impact the value or liquidity of the fund’s investments and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. In addition, the fund’s investments in foreign securities may be subject to economic sanctions or other government restrictions, including trade tariffs, embargoes or limitations on trade which could have a significant impact on a country’s markets overall as well as global economies or markets. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions. The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. The fund may also experience more rapid or extreme changes in value as compared to a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. To the extent the fund’s investments in a single country or a limited number of countries represent a large percentage of the fund’s assets, the fund’s performance may be adversely affected by the economic, political, regulatory and social conditions in those countries, and the fund’s price may be more volatile than the price of a fund that is geographically diversified.

Depositary Receipt Risk — Foreign securities also include ADRs, which are U.S. dollar-denominated receipts representing shares of foreign-based corporations. ADRs are issued by U.S. banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Foreign securities also include GDRs, which are similar to ADRs, but are shares of foreign-based corporations generally issued by international banks in one or more markets around the world. In addition, foreign securities include EDRs, which are similar to GDRs, but are shares of foreign-based corporations generally issued by European banks that trade on exchanges outside of the bank’s home country. Investment in ADRs, GDRs and EDRs may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile.

Variable Interest Entities (VIEs) Risk — The fund may gain exposure to certain operating companies in China through legal structures known as VIEs. In China, ownership of companies in certain sectors by non-Chinese individuals and entities (including U.S. persons and entities, such as the fund) is prohibited. To facilitate indirect non-Chinese investment, many China-based operating companies have created VIE structures. In a VIE structure, a China-based operating company will establish an entity outside of China that will enter into service and other contracts with the China-based operating company. Shares of the entities established outside of China are often listed and traded on an exchange. Non-Chinese investors (such as the fund) hold equity interests in the entities established outside of China rather than directly in the China-based operating companies. This arrangement allows U.S. investors to obtain economic exposure to the China-based operating company through contractual means rather than through formal equity ownership. An investment in a VIE structure subjects the fund to the risks associated with the underlying China-based operating company. In addition, the fund may be exposed to certain associated risks, including the risks that: the Chinese government could subject the China-based operating company to penalties, revocation of business and operating licenses or forfeiture of ownership interests; the Chinese government may outlaw the VIE structure, which could cause an uncertain negative impact to existing investors in the VIE structure; the contracts underlying the VIE structure may not be enforced by Chinese courts; and shareholders of the China-based operating company may leverage the VIE structure to their benefit and to the detriment of the investors in the VIE structure. If these actions were to occur, the market value of the fund’s investments in the VIE structure would likely fall, causing investment losses, which could be substantial, for the fund.

Currency Risk — The fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, will subject the fund to the risk that those currencies will decline in value relative to the U.S. dollar. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund; or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or monies in settlement of obligations. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a counterparty’s failure, inability or refusal to perform with respect to such contracts.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in the index, match the securities’ weighting to the index, or the fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. In addition, the fund may not invest in issuers located in certain countries due to these considerations. The fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the fund may value individual securities based on fair value prices developed using methods approved by the fund’s Board of Trustees. To the extent the fund calculates its net asset value (NAV) based on fair value prices, the fund’s performance may diverge from that of its index. In addition, cash flows into and out of the fund, timing variances, operating expenses and trading costs all affect the ability of the fund to match the performance of the index, because the index does not have to manage cash flows and does not incur any costs. Tracking error may also be impacted by timing differences in currency conversions between the fund and the index and by the fund’s use of fair valuation. Lastly, differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index impact correlation between the performance of the fund and that of its index.

Derivatives Risk — The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. The fund’s use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain of these risks, such as liquidity risk, leverage risk, and market risk, are discussed elsewhere in this prospectus. The fund’s use of derivatives is also subject to counterparty risk, lack of availability risk, valuation risk, correlation risk, tax risk, and operational risk. Counterparty risk is the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations either because the financial condition of the counterparty declines, or because the counterparty is otherwise unable or unwilling to perform under the contract. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gains. Operational risk is the risk related to operational issues, including documentation issues, settlement issues, systems failures, inadequate controls, and human error. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. The fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that the fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

Liquidity Risk — Liquidity risk exists when particular investments may be difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities which means even a small amount of leverage can have a disproportionately large impact on the fund. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Securities Lending Risk — The fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares. Trading of shares of the fund on a national securities exchange may be halted if exchange officials deem such action appropriate, if the fund is delisted, or if the activation of marketwide “circuit breakers” halts stock trading generally. If the fund’s shares are delisted, the fund may seek to list its shares on another market, merge with another ETF, or redeem its shares at NAV.

Shares of the Fund May Trade at Prices Other Than NAV — As with all ETFs, fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s NAV, there may be times when the market price and the NAV vary significantly. Thus, an investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The investment adviser cannot predict whether shares will trade above (premium), below (discount) or at NAV. The fund may have a limited number of financial institutions that may act as “Authorized Participants” or market makers. Only Authorized Participants who have entered into agreements with the fund’s distributor may engage in creation or redemption transactions directly with the fund (as discussed in the “Creation and Redemption” section below). If those Authorized Participants exit the business or are unable to process creation and/or redemption orders (including in situations where Authorized Participants have limited or diminished access to capital required to post collateral), and no other Authorized Participant is able to step forward to create and redeem in either of these cases, fund shares may trade at a premium or discount to NAV like closed-end fund shares (and may even face delisting). Similar effects may result if market makers exit the business or are unable to continue making markets in the fund’s shares. Risks associated with having a limited number of Authorized Participants may be heightened for ETFs that invest in securities issued by non-U.S. issuers or other instruments that have lower trading volumes. More generally, market makers are not obligated to make a market in the fund’s shares, and Authorized Participants are not obligated to submit purchase or redemption orders for Creation Units. Further, while the creation/redemption feature is designed to make it likely that shares normally will trade close to the value of the fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the fund’s holdings. In addition, transactions by large shareholders may account for a large percentage of trading volume on the fund’s primary listing exchange and may, therefore, have a material effect on the market price of the fund’s shares.

The market price of fund shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade the fund shares. The bid/ask spread on ETF shares varies over time based on the fund’s trading volume and market liquidity. As a result, the bid/ask spread on ETF shares is generally larger when the shares have little trading volume or market liquidity and generally lower when the shares have high trading volume or market liquidity. In addition, in times of severe market disruption, the bid/ask spread can increase significantly. At those times, fund shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that investors most want to sell shares. The investment adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities. There are various methods by which investors can purchase and sell shares of the fund and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the fund.

In addition, the securities held by the fund are generally traded in markets that close at a different time than the fund’s secondary market and liquidity in those securities may be reduced after the applicable market closing times. Accordingly, during the time when the fund’s secondary market is open but after the applicable foreign market closing, fixing or settlement times, bid/ask spreads and the resulting premium or discount to the fund’s NAV may widen. The fund’s bid/ask spread may also be impacted by the liquidity of the underlying securities held by the fund or in instances of significant volatility of the underlying securities.

More Information About Principal Investment Risks

The fund is subject to risks, any of which could cause an investor to lose money.

Market Risk — Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs, and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and the fund’s investments. As with any investment whose performance is tied to financial markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Style Risk — The fund is an index fund. Therefore, the fund follows the securities included in the index, which may include real estate investment trusts, during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market, even though these securities may go in and out of favor based on market and economic conditions. The index does not weigh securities on the basis of investor protection, limitations or differences in the quality of financial reporting or other oversight mechanisms. Therefore, the fund will follow the securities in the index without consideration of these factors. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index.

At times the segment of the markets represented by the index may underperform other market segments. A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. Because of the way the index is composed, the index may perform differently or worse than an index that is based solely on market capitalization.

Index-Related Risk — The index provider does not provide any warranty as to the timeliness, accuracy or completeness of any data relating to the index. Errors relating to the index, including index data, computations and/or construction, may occur from time to time and may not be identified by the index provider for a period of time or at all. Losses resulting from index errors may be borne by the fund and its shareholders. In addition, there can be no guarantee that the index will operate as intended during volatile market conditions or over the course of a full market cycle.

In addition, market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities markets as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Small-Cap Company Risk — Small-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by larger companies. The value of securities issued by small-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns. In addition, small-cap companies may have limited financial resources, management experience, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. Further, small-cap companies may have less publicly available information and such information may be inaccurate or incomplete.

Real Estate Investment Trusts (REITs) Risk — Although the fund does not invest directly in real estate, due to the composition of the index, the fund may have exposure to securities of REITs. Equity REITs may be affected by changes in the value of the underlying properties owned by the trusts. Further, REITs are dependent upon specialized management skills and may have their investments in relatively few properties,

or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. The value of a REIT will also rise and fall in response to the creditworthiness of the issuer. In particular, the value of these securities may be affected by changes in interest rates. In addition, REITs could possibly fail to qualify for tax free pass-through of income under the Internal Revenue Code of 1986, as amended, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended. The failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses. Further, dividends paid by REITs are taxed as ordinary income and generally do not qualify for the preferential rate applicable to qualified dividend income. REITs may be more volatile and/or more illiquid than other types of securities.

Foreign Investment Risk — The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the U.S. These risks may negatively impact the value or liquidity of the fund’s investments and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. In addition, the fund’s investments in foreign securities may be subject to economic sanctions or other government restrictions, including trade tariffs, embargoes or limitations on trade which could have a significant impact on a country’s markets overall as well as global economies or markets. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions. The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. The fund may also experience more rapid or extreme changes in value as compared to a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. To the extent the fund’s investments in a single country or a limited number of countries represent a large percentage of the fund’s assets, the fund’s performance may be adversely affected by the economic, political, regulatory and social conditions in those countries, and the fund’s price may be more volatile than the price of a fund that is geographically diversified.

Depositary Receipt Risk — Foreign securities also include ADRs, which are U.S. dollar-denominated receipts representing shares of foreign-based corporations. ADRs are issued by U.S. banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Foreign securities also include GDRs, which are similar to ADRs, but are shares of foreign-based corporations generally issued by international banks in one or more markets around the world. In addition, foreign securities include EDRs, which are similar to GDRs, but are shares of foreign-based corporations generally issued by European banks that trade on exchanges outside of the bank’s home country. Investment in ADRs, GDRs and EDRs may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile.

Variable Interest Entities (VIEs) Risk — The fund may gain exposure to certain operating companies in China through legal structures known as VIEs. In China, ownership of companies in certain sectors by non-Chinese individuals and entities (including U.S. persons and entities, such as the fund) is prohibited. To facilitate indirect non-Chinese investment, many China-based operating companies have created VIE structures. In a VIE structure, a China-based operating company will establish an entity outside of China that will enter into service and other contracts with the China-based operating company. Shares of the entities established outside of China are often listed and traded on an exchange. Non-Chinese investors (such as the fund) hold equity interests in the entities established outside of China rather than directly in the China-based operating companies. This arrangement allows U.S. investors to obtain economic exposure to the China-based operating company through contractual means rather than through formal equity ownership. An investment in a VIE structure subjects the fund to the risks associated with the underlying China-based operating company. In addition, the fund may be exposed to certain associated risks, including the risks that: the Chinese government could subject the China-based operating company to penalties, revocation of business and operating licenses or forfeiture of ownership interests; the Chinese government may outlaw the VIE structure, which could cause an uncertain negative impact to existing investors in the VIE structure; the contracts underlying the VIE structure may not be enforced by Chinese courts; and shareholders of the China-based operating company may leverage the VIE structure to their benefit and to the detriment of the investors in the VIE structure. If these actions were to occur, the market value of the fund’s investments in the VIE structure would likely fall, causing investment losses, which could be substantial, for the fund.

Currency Risk — The fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, will subject the fund to the risk that those currencies will decline in value relative to the U.S. dollar. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund; or by the imposition of currency controls or

other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or monies in settlement of obligations. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a counterparty’s failure, inability or refusal to perform with respect to such contracts.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in the index, match the securities’ weighting to the index, or the fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. In addition, the fund may not invest in issuers located in certain countries due to these considerations. The fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the fund may value individual securities based on fair value prices developed using methods approved by the fund’s Board of Trustees. To the extent the fund calculates its net asset value (NAV) based on fair value prices, the fund’s performance may diverge from that of its index. In addition, cash flows into and out of the fund, timing variances, operating expenses and trading costs all affect the ability of the fund to match the performance of the index, because the index does not have to manage cash flows and does not incur any costs. Tracking error may also be impacted by timing differences in currency conversions between the fund and the index and by the fund’s use of fair valuation. Lastly, differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index impact correlation between the performance of the fund and that of its index.

Derivatives Risk — The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. The fund’s use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain of these risks, such as liquidity risk, leverage risk, and market risk, are discussed elsewhere in this prospectus. The fund’s use of derivatives is also subject to counterparty risk, lack of availability risk, valuation risk, correlation risk, tax risk, and operational risk. Counterparty risk is the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations either because the financial condition of the counterparty declines, or because the counterparty is otherwise unable or unwilling to perform under the contract. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gains. Operational risk is the risk related to operational issues, including documentation issues, settlement issues, systems failures, inadequate controls, and human error. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. The fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that the fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

Liquidity Risk — Liquidity risk exists when particular investments may be difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities which means even a small amount of leverage can have a disproportionately large impact on the fund. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Securities Lending Risk — The fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance

will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares. Trading of shares of the fund on a national securities exchange may be halted if exchange officials deem such action appropriate, if the fund is delisted, or if the activation of marketwide “circuit breakers” halts stock trading generally. If the fund’s shares are delisted, the fund may seek to list its shares on another market, merge with another ETF, or redeem its shares at NAV.

Shares of the Fund May Trade at Prices Other Than NAV — As with all ETFs, fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s NAV, there may be times when the market price and the NAV vary significantly. Thus, an investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The investment adviser cannot predict whether shares will trade above (premium), below (discount) or at NAV. The fund may have a limited number of financial institutions that may act as “Authorized Participants” or market makers. Only Authorized Participants who have entered into agreements with the fund’s distributor may engage in creation or redemption transactions directly with the fund (as discussed in the “Creation and Redemption” section below). If those Authorized Participants exit the business or are unable to process creation and/or redemption orders (including in situations where Authorized Participants have limited or diminished access to capital required to post collateral), and no other Authorized Participant is able to step forward to create and redeem in either of these cases, fund shares may trade at a premium or discount to NAV like closed-end fund shares (and may even face delisting). Similar effects may result if market makers exit the business or are unable to continue making markets in the fund’s shares. Risks associated with having a limited number of Authorized Participants may be heightened for ETFs that invest in securities issued by non-U.S. issuers or other instruments that have lower trading volumes. More generally, market makers are not obligated to make a market in the fund’s shares, and Authorized Participants are not obligated to submit purchase or redemption orders for Creation Units. Further, while the creation/redemption feature is designed to make it likely that shares normally will trade close to the value of the fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the fund’s holdings. In addition, transactions by large shareholders may account for a large percentage of trading volume on the fund’s primary listing exchange and may, therefore, have a material effect on the market price of the fund’s shares.

The market price of fund shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade the fund shares. The bid/ask spread on ETF shares varies over time based on the fund’s trading volume and market liquidity. As a result, the bid/ask spread on ETF shares is generally larger when the shares have little trading volume or market liquidity and generally lower when the shares have high trading volume or market liquidity. In addition, in times of severe market disruption, the bid/ask spread can increase significantly. At those times, fund shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that investors most want to sell shares. The investment adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities. There are various methods by which investors can purchase and sell shares of the fund and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the fund.

In addition, the securities held by the fund are generally traded in markets that close at a different time than the fund’s secondary market and liquidity in those securities may be reduced after the applicable market closing times. Accordingly, during the time when the fund’s secondary market is open but after the applicable foreign market closing, fixing or settlement times, bid/ask spreads and the resulting premium or discount to the fund’s NAV may widen. The fund’s bid/ask spread may also be impacted by the liquidity of the underlying securities held by the fund or in instances of significant volatility of the underlying securities.

Schwab Fundamental Emerging Markets Equity ETF

Investment Objective

The fund’s goal is to track as closely as possible, before fees and expenses, the total return of an index that measures the performance of large sized companies, based on their fundamental size and weight, in emerging market countries. The fund’s investment objective is not fundamental and therefore may be changed by the fund’s Board of Trustees without shareholder approval.

Index

As of February 28, 2026, the RAFI Fundamental High Liquidity Emerging Markets Index consisted of 335 constituent companies which had an average market capitalization of $184 billion (the market capitalization of the constituent companies ranged from $357 million to $1.7 trillion). The index is owned by RAFI Indices, LLC, a wholly owned subsidiary of Research Affiliates Global Holdings, LLC.

More Information About Principal Investment Risks

The fund is subject to risks, any of which could cause an investor to lose money.

Market Risk — Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs, and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and the fund’s investments. As with any investment whose performance is tied to financial markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.

Investment Style Risk — The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market, even though these securities may go in and out of favor based on market and economic conditions. The index does not weigh securities on the basis of investor protection, limitations or differences in the quality of financial reporting or other oversight mechanisms. Therefore, the fund will follow the securities in the index without consideration of these factors. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index.

At times the segment of the markets represented by the index may underperform other market segments. A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. Because of the way the index is composed, the index may perform differently or worse than an index that is based solely on market capitalization.

Index-Related Risk — The index provider does not provide any warranty as to the timeliness, accuracy or completeness of any data relating to the index. Errors relating to the index, including index data, computations and/or construction, may occur from time to time and may not be identified by the index provider for a period of time or at all. Losses resulting from index errors may be borne by the fund and its shareholders. In addition, there can be no guarantee that the index will operate as intended during volatile market conditions or over the course of a full market cycle.

In addition, market disruptions could cause delays in the index’s rebalancing schedule which may result in the index and, in turn, the fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule.

Equity Risk — The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities markets as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Large-Cap Company Risk — Large-cap companies are generally more mature than smaller companies. They also may have fewer new market opportunities for their products or services, may focus resources on maintaining their market share, and may be unable to respond quickly to new competitive challenges. As a result, the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

Foreign Investment Risk — The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the U.S. These risks may negatively impact the value or liquidity of the fund’s investments and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. In addition, the fund’s investments in foreign securities may be subject to economic sanctions or other government restrictions, including trade tariffs, embargoes or limitations on trade which could have a significant impact on a country’s markets overall as well as global economies or markets. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions. The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. The fund may also experience more rapid or extreme changes in value as compared to a fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. To the extent the fund’s investments in a single country or a limited number of countries represent a large percentage of the fund’s assets, the fund’s performance may be adversely affected by the economic, political, regulatory and social conditions in those countries, and the fund’s price may be more volatile than the price of a fund that is geographically diversified.

Depositary Receipt Risk — Foreign securities also include ADRs, which are U.S. dollar-denominated receipts representing shares of foreign-based corporations. ADRs are issued by U.S. banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Foreign securities also include GDRs, which are similar to ADRs, but are shares of foreign-based corporations generally issued by international banks in one or more markets around the world. In addition, foreign securities include EDRs, which are similar to GDRs, but are shares of foreign-based corporations generally issued by European banks that trade on exchanges outside of the bank’s home country. Investment in ADRs, GDRs and EDRs may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile.

Variable Interest Entities (VIEs) Risk — The fund may gain exposure to certain operating companies in China through legal structures known as VIEs. In China, ownership of companies in certain sectors by non-Chinese individuals and entities (including U.S. persons and entities, such as the fund) is prohibited. To facilitate indirect non-Chinese investment, many China-based operating companies have created VIE structures. In a VIE structure, a China-based operating company will establish an entity outside of China that will enter into service and other contracts with the China-based operating company. Shares of the entities established outside of China are often listed and traded on an exchange. Non-Chinese investors (such as the fund) hold equity interests in the entities established outside of China rather than directly in the China-based operating companies. This arrangement allows U.S. investors to obtain economic exposure to the China-based operating company through contractual means rather than through formal equity ownership. An investment in a VIE structure subjects the fund to the risks associated with the underlying China-based operating company. In addition, the fund may be exposed to certain associated risks, including the risks that: the Chinese government could subject the China-based operating company to penalties, revocation of business and operating licenses or forfeiture of ownership interests; the Chinese government may outlaw the VIE structure, which could cause an uncertain negative impact to existing investors in the VIE structure; the contracts underlying the VIE structure may not be enforced by Chinese courts; and shareholders of the China-based operating company may leverage the VIE structure to their benefit and to the detriment of the investors in the VIE structure. If these actions were to occur, the market value of the fund’s investments in the VIE structure would likely fall, causing investment losses, which could be substantial, for the fund.

Emerging Markets Risk — The risks of foreign investments apply to, and may be heightened in connection with, investments in emerging market countries or securities of issuers that conduct their business in emerging markets. Emerging market countries may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. Emerging market countries often have less uniformity in accounting, auditing, financial reporting and recordkeeping requirements, which may limit the quality and availability of financial information, and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries. Material information about a company in an emerging market country may be unavailable or unreliable, and U.S. regulators may be unable to enforce a company’s regulatory obligations. There is often a greater potential for nationalization, expropriation, confiscatory taxation, government regulation, social instability or diplomatic developments (including war) in emerging market countries, which could adversely affect the economies of, or investments in securities of issuers located in, such countries. In addition, emerging markets are substantially smaller than developed markets, and the financial stability of issuers (including governments) in emerging market countries may be more precarious than in developed countries. As a result, there will tend to be an increased risk of illiquidity and price volatility associated with the fund’s investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.

Currency Risk — The fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, will subject the fund to the risk that those currencies will decline in value relative to the U.S. dollar. In either event, the dollar value of an investment in the fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which

makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund; or by the imposition of currency controls or other political developments in the United States or abroad. These can result in losses to the fund if it is unable to deliver or receive currency or monies in settlement of obligations. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the fund’s account. The fund is subject to the risk of a counterparty’s failure, inability or refusal to perform with respect to such contracts.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. The divergence between the performance of the fund and the index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, the fund may not invest in certain securities in the index, match the securities’ weighting to the index, or the fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. In addition, the fund may not invest in issuers located in certain countries due to these considerations. The fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the fund may value individual securities based on fair value prices developed using methods approved by the fund’s Board of Trustees. To the extent the fund calculates its net asset value (NAV) based on fair value prices, the fund’s performance may diverge from that of its index. In addition, cash flows into and out of the fund, timing variances, operating expenses and trading costs all affect the ability of the fund to match the performance of the index, because the index does not have to manage cash flows and does not incur any costs. Tracking error may also be impacted by timing differences in currency conversions between the fund and the index and by the fund’s use of fair valuation. Lastly, differences between the fund’s portfolio and the index resulting from legal restrictions (such as diversification requirements) that apply to the fund but not to the index impact correlation between the performance of the fund and that of its index.

Derivatives Risk — The fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. The fund’s use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Certain of these risks, such as liquidity risk, leverage risk, and market risk, are discussed elsewhere in this prospectus. The fund’s use of derivatives is also subject to counterparty risk, lack of availability risk, valuation risk, correlation risk, tax risk, and operational risk. Counterparty risk is the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations either because the financial condition of the counterparty declines, or because the counterparty is otherwise unable or unwilling to perform under the contract. Lack of availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gains. Operational risk is the risk related to operational issues, including documentation issues, settlement issues, systems failures, inadequate controls, and human error. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. The fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that the fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

Liquidity Risk — Liquidity risk exists when particular investments may be difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, the fund, due to limitations on investments in illiquid securities and the difficulty in readily purchasing and selling such securities at favorable times or prices, may decline in value, experience lower returns and/or be unable to achieve its desired level of exposure to a certain issuer or sector. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities.

Leverage Risk — Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any decrease or increase in the value of the fund’s portfolio securities which means even a small amount of leverage can have a disproportionately large impact on the fund. The use of leverage may cause the fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

Securities Lending Risk — The fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. The fund will also bear the risk of any decline in value of securities acquired with cash collateral. The fund may pay lending fees to a party arranging the loan.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares. Trading of shares of the fund on a national securities exchange may be halted if exchange officials deem such action appropriate, if the fund is delisted, or if the activation of marketwide “circuit breakers” halts stock trading generally. If the fund’s shares are delisted, the fund may seek to list its shares on another market, merge with another ETF, or redeem its shares at NAV.

Shares of the Fund May Trade at Prices Other Than NAV — As with all ETFs, fund shares may be bought and sold in the secondary market at market prices.

This section provides further details about each fund’s financial history for the past five years. Certain information reflects financial results for a single fund share. “Total return” shows the percentage that an investor in a fund would have earned or lost during a given period, assuming all distributions were reinvested. The information has been audited by the funds' independent registered public accounting firm, Deloitte & Touche LLP (Deloitte). Deloitte’s full report is included in each fund’s annual holdings and financial statements, which are included in each fund’s Form N-CSR (see back cover).
