Investment Advisor/Portfolio Management

Dimensional Fund Advisors LP serves as the investment advisor for the US Sustainability ETF. The following individuals are responsible for leading the day-to-day management of the Portfolio:

Purchase and Sale of Fund Shares

The US Sustainability ETF issues (or redeems) shares at NAV only to certain financial institutions that have entered into agreements with the Portfolio’s distributor in large aggregated blocks known as “Creation Units.” A Creation Unit of the Portfolio consists of 50,000 shares. Creation Units are issued (or redeemed) in-kind for securities (and an amount of cash) that the Portfolio specifies each day at the NAV next determined after receipt of an order.

Individual Portfolio shares may only be purchased and sold on NYSE Arca, Inc., other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Because Portfolio shares trade at market prices rather than at NAV, Portfolio shares may trade at a price less than (discount) or greater than (premium) the Portfolio’s NAV. Recent information, including information on the Portfolio’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the Portfolio’s website at https://www.dimensional.com/us-en/funds.

Tax Information

The dividends and distributions you receive from the US Sustainability ETF are taxable and generally will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case distributions may be taxed as ordinary income when withdrawn from the plan or account.

Payments to Financial Intermediaries

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

Additional Information on Investment Objectives and Policies

Dimensional ETF Trust (the “Trust”) offers a variety of investment portfolios. Each of the investment company’s portfolios has its own investment objective and is the equivalent of a separate exchange-traded fund (“ETF”). Shares of the Dimensional US Sustainability Core 1 ETF (the “US Sustainability ETF”), Dimensional International Sustainability Core 1 ETF (the “International Sustainability ETF”), Dimensional Emerging Markets Sustainability Core 1 ETF (the “Emerging Markets Sustainability ETF”) (each, an “Equity Portfolio” and collectively, the “Equity Portfolios”), and Dimensional Global Sustainability Fixed Income ETF (the “Global Sustainability Fixed Income ETF”) are offered in this Prospectus. The Portfolios are designed for long-term investors.

The investment objective of each Portfolio (excluding the Global Sustainability Fixed Income ETF) is to achieve long-term capital appreciation. The investment objective of the Global Sustainability Fixed Income ETF is to seek to maximize total returns from the universe of debt securities in which the Portfolio invests. Total return is comprised of income and capital appreciation.

Each Portfolio’s investment objective is non-fundamental, which means it may be changed by the Board of Trustees without shareholder approval. Shareholders will be given at least 60 days’ advance notice of any change to a Portfolio’s investment objective.

Investment Terms Used in the Prospectus

Below are the definitions of some terms that the Advisor uses to describe the investment strategies for certain Equity Portfolios.

Free Float generally describes the number of publicly traded shares of a company.

Price Momentum generally describes the past performance of a stock relative to other stocks.

Trading Strategies generally refers to the ability to execute purchases and sales of stocks in a cost-effective manner.

Profitability generally measures a company’s profit in relation to its book value or assets.

US Sustainability ETF

The US Sustainability ETF seeks to achieve its investment objective by purchasing a broad and diverse group of securities of U.S. companies. The Portfolio invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies relative to the U.S. Universe, while, relative to a portfolio without the sustainability impact considerations, excluding or underweighting securities of companies that, according to the Portfolio’s sustainability impact considerations, may be less sustainable and overweighting securities of companies that may be more sustainable. (See “Applying the Sustainability Portfolios’ Sustainability Impact Considerations” in this Prospectus). The Advisor generally defines the “U.S. Universe” as a market capitalization weighted set of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Market capitalization weighted means that a company’s weighting in the U.S. Universe is proportional to that company’s actual market capitalization compared to the total market capitalization of all eligible companies. The higher the company’s relative market capitalization, the greater its representation. The increased exposure to smaller capitalization, lower relative price, and higher profitability companies may be achieved by decreasing the allocation of the Portfolio’s assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the U.S. Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors, such as price-to-cash-flow or price-to-earnings ratios, as well as economic conditions and developments in the issuer’s industry. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time. The Advisor

27

may also adjust the representation in the Portfolio of an eligible company, or exclude a company, after considering such factors as free float, price momentum, trading strategies, liquidity, size, relative price, profitability, investment characteristics, and other factors that the Advisor determines to be appropriate. The Advisor may decrease the amount that the Portfolio invests in small capitalization companies that have lower profitability and/or higher relative prices. The Advisor may consider a small capitalization company’s investment characteristics as compared to other eligible companies when making investment decisions and may exclude a small capitalization company with high investment as measured by the company’s recent asset growth. The Portfolio will generally not exclude more than 5% of the eligible small capitalization companies within the U.S. Universe based on such investment characteristics. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. The implementation and management of the Advisor’s “Sustainability” portfolios, including without limitation, the Portfolio is protected by U.S. Patent Nos. 7,596,525 B1 and 7,599,874 B1.

The US Sustainability ETF may purchase or sell futures contracts and options on futures contracts for U.S. equity securities and indices, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio. The Portfolio does not intend to sell futures contracts to establish short positions in individual securities or to use derivatives for purposes of speculation or leveraging investment returns. The above-referenced investments are not subject to, though they may incorporate, the Portfolio’s sustainability impact considerations.

The US Sustainability ETF may invest in exchange-traded funds (ETFs) for the purpose of gaining exposure to the U.S. stock market while maintaining liquidity. In addition to money market instruments and other short-term investments, the Portfolio may invest in affiliated and unaffiliated registered and unregistered money market funds to manage the Portfolio’s cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in ETFs and money market funds may involve a duplication of certain fees and expenses. The above-referenced investments are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

International Sustainability ETF

The International Sustainability ETF seeks to achieve its investment objective by purchasing a broad and diverse group of securities of non-U.S. companies. The Portfolio invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies relative to the International Universe, while, relative to a portfolio without sustainability impact considerations, excluding or underweighting securities of companies that, according to the Portfolio’s sustainability impact considerations, may be less sustainable and overweighting securities of companies that may be more sustainable. (See “Applying the Sustainability Portfolios’ Sustainability Impact Considerations” in this Prospectus). For purposes of this Portfolio, the Advisor defines the “International Universe” as a market capitalization weighted set of non-U.S. companies in developed markets that have been authorized for investment by the Advisor’s Investment Committee. Market capitalization weighted means that a company’s weighting in the International Universe is proportional to that company’s actual market capitalization compared to the total market capitalization of all eligible companies. The higher the company’s relative market capitalization, the greater its representation. As of the date of this Prospectus, the following markets have been authorized for investment for the Portfolio and comprise the International Universe: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom (collectively, the “Approved Markets”). The Advisor will determine, in its discretion, when and whether to invest in countries that have been authorized as Approved Markets, depending on a number of factors, including, but not limited to, asset growth in the Portfolio, constraints imposed in Approved Markets, and other characteristics of each country’s markets. The Investment Committee of the Advisor also may authorize other markets for investment in the future, in addition to the Approved Markets identified above, or may remove one or more markets from the list of Approved Markets. Although the Advisor does not intend to purchase securities not associated with an Approved Market, the Portfolio may acquire such securities in connection with corporate actions or other reorganizations or transactions with respect to securities that are held by the Portfolio from time to time. Also, the Portfolio may continue to hold investments in countries that are not currently designated as Approved Markets, but had been authorized for investment in the past, and may reinvest distributions received in connection with such existing investments in such previously Approved Markets. (For a description of the securities approved for investment,

28

see “Approved Markets”). The implementation and management of the Advisor’s “Sustainability” portfolios, including without limitation, the Portfolio is protected by U.S. Patent Nos. 7,596,525 B1, 7,599,874 B1 and, 8,438,092 B2.

Under normal market conditions, the International Sustainability ETF intends to invest at least 40% of its assets in three or more non-U.S. countries by investing in securities of companies associated with such countries.

The increased exposure to smaller capitalization, lower relative price, and higher profitability companies for the International Sustainability ETF may be achieved by decreasing the allocation of the Portfolio’s assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the International Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors, such as price-to-cash-flow or price-to-earnings ratios, as well as economic conditions and developments in the issuer’s industry. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time. The Advisor may also adjust the representation in the Portfolio of an eligible company, or exclude a company, after considering such factors as free float, price momentum, trading strategies, liquidity, size, relative price, profitability, investment characteristics, and other factors that the Advisor determines to be appropriate. The Advisor may decrease the amount that the Portfolio invests in small capitalization companies that have lower profitability and/or higher relative prices. The Advisor may consider a small capitalization company’s investment characteristics as compared to other eligible companies when making investment decisions and may exclude a small capitalization company with high investment as measured by the company’s recent asset growth. The Portfolio will generally not exclude more than 5% of the eligible small capitalization company universe within each eligible country based on such investment characteristics. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time.

The International Sustainability ETF may purchase or sell futures contracts and options on futures contracts for foreign or U.S. equity securities and indices, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio. The Portfolio does not intend to sell futures contracts to establish short positions in individual securities or to use derivatives for purposes of speculation or leveraging investment returns. The above-referenced investments are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

The International Sustainability ETF may invest in exchange-traded funds (ETFs) for the purpose of gaining exposure to the equity markets while maintaining liquidity. In addition to money market instruments and other short-term investments, the Portfolio may invest in affiliated and unaffiliated registered and unregistered money market funds to manage cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in ETFs and money market funds may involve a duplication of certain fees and expenses. The above-referenced investments are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

Emerging Markets Sustainability ETF

The Emerging Markets Sustainability ETF seeks to achieve its investment objective by investing in companies associated with emerging markets, which may include frontier markets (emerging market countries in an earlier stage of development), authorized for investment by the Advisor’s Investment Committee (“Approved Markets”). The Portfolio invests its assets primarily in Approved Markets equity securities listed on bona fide securities exchanges. As of the date of this Prospectus, the Portfolio invests in the following countries that are designated as Approved Markets: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Kuwait, Malaysia, Mexico, Peru, the Philippines, Poland, Qatar, Saudi Arabia, South Africa, South Korea, Taiwan, Thailand, Turkey, and United Arab Emirates. The Advisor will determine, in its discretion, when and whether to invest in countries that have been authorized as Approved Markets, depending on a number of factors, including, but not limited to, asset growth in the Portfolio, constraints imposed in Approved Markets, and other characteristics of each country’s markets. The Investment Committee of the Advisor may designate other countries as Approved Markets for investment in the future, in addition to the countries identified above, or the

29

Investment Committee may remove one or more countries from the list of Approved Markets. Although the Advisor does not intend to purchase securities not associated with an Approved Market, the Portfolio may acquire such securities in connection with corporate actions or other reorganizations or transactions with respect to securities that are held by the Portfolio from time to time. In addition, the Portfolio may continue to hold investments in countries that are not currently designated as Approved Markets, but had been authorized for investment in the past, and may reinvest distributions received in connection with such existing investments in such previously Approved Markets. (For a description of the securities approved for investment, see “Approved Markets”). The implementation and management of the Advisor’s “Sustainability” portfolios, including, without limitation, the Emerging Markets Sustainability Core 1 ETF, is protected by U.S. Patent Nos. 7,596,525 B1, 7,599,874 B1 and 8,438,092 B2.

The Emerging Markets Sustainability ETF will seek to purchase a broad and diverse group of securities associated with emerging markets. The Portfolio invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the Emerging Markets Universe, while adjusting the composition of the Portfolio based on sustainability impact considerations (See “Applying the Sustainability Portfolios’ Sustainability Impact Considerations” in this Prospectus). For purposes of this Portfolio, the Advisor defines the Emerging Markets Universe as a market capitalization weighted set of companies in Approved Markets. Market capitalization weighted means that a company’s weighting in the Emerging Markets Universe is proportional to that company’s actual market capitalization compared to the total market capitalization of all eligible companies. The higher the company’s relative market capitalization, the greater its representation. The Portfolio’s increased exposure to smaller capitalization, lower relative price, and higher profitability companies may be achieved by decreasing the allocation of the Portfolio’s assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the Emerging Markets Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time. The Advisor may also adjust the representation in the Portfolio of an eligible company, or exclude a company, after considering such factors as free float, price momentum, trading strategies, liquidity, size, relative price, profitability, investment characteristics, and other factors that the Advisor determines to be appropriate. The Advisor may decrease the amount that the Portfolio invests in small capitalization companies that have lower profitability and/or higher relative prices. The Advisor may consider a small capitalization company’s investment characteristics as compared to other eligible companies when making investment decisions and may exclude a small capitalization company with high investment as measured by the company’s recent asset growth. The Portfolio will generally not exclude more than 5% of the eligible small capitalization company universe within each eligible country based on such investment characteristics. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time.

In determining which countries are eligible markets for the Emerging Markets Sustainability ETF, the Advisor may consider various factors, including, without limitation, the data, analysis, and classification of countries published or disseminated by the International Bank for Reconstruction and Development (commonly known as the World Bank), the International Finance Corporation, FTSE International and MSCI. Approved Markets may not include all such emerging markets. In determining whether to approve markets for investment, the Advisor may take into account, among other things, market liquidity, relative availability of investor information, government regulation, including fiscal and foreign exchange repatriation rules and the availability of other access to these markets for the Portfolio.

Pending the investment of new capital in Approved Markets securities, the Emerging Markets Sustainability ETF will typically invest in money market instruments or other highly liquid debt instruments including those denominated in U.S. dollars (including, without limitation, repurchase agreements). In addition, the Portfolio may, for liquidity, or for temporary defensive purposes during periods in which market or economic or political conditions warrant, purchase highly liquid debt instruments or hold freely convertible currencies, although the Portfolio does not expect the aggregate of all such amounts to exceed 20% of its net assets under normal circumstances.

30

The Emerging Markets Sustainability ETF does not seek current income as an investment objective, and investments will not be based upon an issuer’s dividend payment policy or record. However, many of the companies whose securities will be included in the Portfolio do pay dividends. It is anticipated, therefore, that the Portfolio will receive dividend income.

In addition to money market instruments and other short-term investments, the Emerging Markets Sustainability ETF may invest in affiliated and unaffiliated registered and unregistered money market funds to manage cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in money market funds may involve a duplication of certain fees and expenses. The Portfolio may also purchase or sell futures contracts and options on futures contracts for Approved Markets or other equity market securities and indices, including those of the United States, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio. The Portfolio does not intend to sell futures contracts to establish short positions in individual securities or to use derivatives for purposes of speculation or leveraging investment returns. The above-referenced investments are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

The Emerging Markets Sustainability ETF may also invest in China A-shares (equity securities of companies listed in China) that are accessible through the Shanghai-Hong Kong Stock Connect program or the Shenzhen-Hong Kong Stock Connect program (together, “Stock Connect”) and variable interest entities (special structures that utilize contractual arrangements to provide exposure to certain Chinese companies).

APPROVED MARKETS

The International Sustainability ETF and Emerging Markets Sustainability ETF, (each an “International Portfolio” and collectively, the “International Portfolios”) each invests in securities of Approved Markets as identified above for each International Portfolio. The Approved Markets securities invested in by each International Portfolio will be listed on bona fide securities exchanges or traded on the over-the-counter markets. These exchanges or over-the-counter markets may be either within or outside the issuer’s domicile country. For example, the securities may be listed or traded in the form of European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”), American Depositary Receipts (“ADRs”), or other types of depositary receipts (including non-voting depositary receipts) or may be listed on bona fide securities exchanges in more than one country. Approved Market securities are defined as securities that are associated with an Approved Market (“Approved Market Securities”). Approved Market Securities are: (a) securities of companies that are organized under the laws of, or maintain their principal place of business in, an Approved Market; (b) securities for which the principal trading market is in an Approved Market; (c) securities issued or guaranteed by the government of an Approved Market country, its agencies or instrumentalities, or the central bank of such country; (d) securities of companies that derive at least 50% of their revenues or profits from goods produced or sold, investments made, or services performed in Approved Markets or have at least 50% of their assets in Approved Markets; (e) securities included in the International Portfolio’s benchmark index, which tracks Approved Markets; or (f) depositary shares of companies associated with Approved Markets under the criteria above. Securities of Approved Markets may include securities of companies that have characteristics and business relationships common to companies in other countries. As a result, the value of the securities of such companies may reflect economic and market forces in such other countries as well as in the Approved Markets. The Advisor, however, will select only those companies that, in its view, have sufficiently strong exposure to economic and market forces in Approved Markets that satisfy the criteria described above. The International Portfolios also may obtain exposure to Approved Market Securities by investing in derivative instruments that derive their value from Approved Market Securities, or by investing in securities of pooled investment vehicles that invest at least 80% of their assets in Approved Market Securities.

Global Sustainability Fixed Income ETF

The following is a description of the categories of investments that may be acquired by the Global Sustainability Fixed Income ETF:

1.  U.S. Government Obligations—Debt securities issued by the U.S. Treasury that are direct obligations of the U.S. Government, including bills, notes and bonds. These securities may also be purchased on a “when-issued” basis.

31

2.  U.S. Government Agency Obligations—Issued or guaranteed by U.S. government-sponsored instrumentalities and federal agencies, which have different levels of credit support. The U.S. government agency obligations include, but are not limited to, securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, including Ginnie Mae mortgage pass-through securities. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government may be supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limits, such as securities issued by Federal Home Loan Banks, or are supported only by the credit of such agencies, such as Freddie Mac and Fannie Mae, including their mortgage pass-through securities. These securities may also be purchased on a “when-issued” or “to-be- announced” basis, such as mortgage TBAs.

3.  Corporate Debt Obligations—Corporate debt securities (e.g., bonds and debentures), which have received an investment grade rating by Moody’s, Fitch or S&P, or an equivalent rating assigned by another nationally recognized statistical rating organization (“NRSRO”), or, if unrated, have been determined by the Advisor to be of comparable quality.

4.  Bank Obligations—Obligations of U.S. banks and savings and loan associations and dollar-denominated obligations of U.S. subsidiaries and branches of foreign banks, such as certificates of deposit (including marketable variable rate certificates of deposit), time deposits and bankers’ acceptances. Bank certificates of deposit will be acquired only from banks having assets in excess of $1,000,000,000.

5.  Commercial Paper—Rated, at the time of purchase, A3 or better by S&P or Prime3 or better by Moody’s, or F3 or better by Fitch, or an equivalent rating assigned by another NRSRO, or, if unrated, issued by a corporation having an outstanding unsecured debt issue rated at least Baa3 by Moody’s or BBB- by S&P or Fitch.

6.  Repurchase Agreements—Instruments through which the Portfolio purchases securities (“underlying securities”) from a bank, a registered U.S. government securities dealer, or other such counterparties with creditworthiness and other characteristics deemed appropriate by the Advisor, with an agreement by the seller to repurchase the securities at an agreed price, plus interest at a specified rate. The underlying securities will be limited to U.S. government and agency obligations described in (1) and (2) above. The Portfolio will not enter into a repurchase agreement with a duration of more than seven days if, as a result, more than 10% of the value of its total assets would be so invested. In addition, a repurchase agreement with a duration of more than seven days will be subject to the Portfolio’s investment restriction on illiquid investments. The Portfolio also will only invest in repurchase agreements with banks, U.S. government securities dealers, and/or other counterparties, as described above, that are approved by the Investment Committee of the Advisor. The Advisor will monitor the market value of the securities plus any accrued interest thereon so that they will at least equal the repurchase price.

7.  Foreign Government and Agency Obligations—Bills, notes, bonds, and other debt securities issued or guaranteed by foreign governments, or their authorities, agencies, instrumentalities or political subdivisions.

8.  Supranational Organization Obligations—Debt securities of supranational organizations such as the European Investment Bank, the Inter-American Development Bank or the World Bank, which are chartered to promote economic development.

9.  Foreign Issuer Obligations—Debt securities of non-U.S. issuers that have received a rating of BBB- or better by S&P or Fitch or Baa3 or better by Moody’s, or an equivalent rating assigned by another NRSRO, or, if unrated, have been determined by the Advisor to be of comparable quality.

10.  Eurodollar Obligations—Debt securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States.

11.  Money Market Funds—The Portfolio may invest in affiliated and unaffiliated registered and unregistered money market funds. The securities purchased by the money market funds are not subject to the social issue screens or sustainability impact considerations that have been identified in this Prospectus. Investments in money market funds may also involve a duplication of certain fees and expenses and are not a principal investment of the Portfolio.

The Global Sustainability Fixed Income ETF’s investments in securities of U.S. and non-U.S. sovereign issuers are not subject to the sustainability impact considerations identified below. The Advisor, however, considers securities issued by the U.S. Treasury and certain U.S. agencies and instrumentalities that are not subject to the

32

sustainability impact considerations identified below to be consistent with the Portfolio’s strategy of investing in sustainable investments. The implementation and management of the Advisor’s “Sustainability” portfolios, including, without limitation, the Global Sustainability Fixed Income ETF, is protected by U.S. Patent Nos. 7,596,525 B1, 7,599,874 B1 and 8,438,092 B2.

The categories of fixed income securities that may be acquired by the Global Sustainability Fixed Income ETF may include both fixed and floating rate securities. Floating rate securities bear interest at rates that vary with prevailing market rates. Interest rate adjustments are made periodically (e.g., every six months), usually based on a money market index such as the Secured Overnight Financing Rate (SOFR) or the Treasury bill rate.

Duration, as discussed with respect to the Global Sustainability Fixed Income ETF’s investment policy regarding duration, is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. For example, when the level of interest rates increases by 0.10%, the price of a fixed income security or a portfolio of fixed income securities having a duration of five years generally will decrease by approximately 0.50%. Conversely, when the level of interest rates decreases by 0.10%, the price of a fixed income security or a portfolio of fixed income securities having a duration of five years generally will increase by approximately 0.50%. In general, greater sensitivity to changes in interest rates typically corresponds to higher volatility and higher risk.

APPLYING THE PORTFOLIOS’ SUSTAINABILITY IMPACT CONSIDERATIONS

The Advisor intends to take into account the impact that companies have on the environment and other sustainability considerations when making investment decisions for the Portfolios. Relative to a portfolio without these considerations, a Portfolio will generally exclude or have less weight in securities of companies that, according to the Portfolios’ sustainability impact considerations, may be less sustainable as compared either to other companies in the Portfolios’ investment universe or other companies with similar business lines. Similarly, relative to a portfolio without sustainability impact considerations, the Portfolios will generally have a higher weight in securities of companies that, according to the Portfolios’ sustainability impact considerations, may be more sustainable as compared either to other companies in the Portfolios’ investment universe or other companies with similar business lines. As of the date of this Prospectus, MSCI ESG Research LLC and Institutional Shareholder Services Inc. have been engaged by the Advisor as the Portfolios’ primary providers of research and/or ratings information relating to the sustainability impact considerations with respect to corporate securities in the portfolios, where information is available from such providers. The Trust or Advisor may also change or engage additional independent third party service providers from time to time.

Selected examples of the types of considerations that are expected to be used to evaluate companies’ impact on the environment and other sustainability considerations are as follows:

33

The sustainability impact considerations listed above are examples of factors that the Advisor believes may indicate whether or not a company, as compared to other companies with similar business lines, promotes sustainability by pursuing economic growth and development that meets the needs of the present without compromising the needs of future generations. The Portfolios may periodically modify, add, or remove their sustainability impact considerations.

For each Portfolio, based on the research and ratings information, the Advisor will determine an overall impact score for the company and will consider the overall impact score of the issuer relative to other issuers when determining whether a security should: (i) be excluded from a Portfolio’s securities holdings; (ii) have its weight decreased within the Portfolios; (iii) be held with no adjustment to its weight within the Portfolios; or (iv) have its weight increased within the Portfolios. The Advisor may also exclude, decrease or increase the weight of specific companies due to any specific factor.

As described above, the Advisor will endeavor to consider the sustainability impact of each company when constructing a Portfolio’s investment portfolio. However, the Advisor may not be able to assess the sustainability impact of each company eligible for purchase by a Portfolio. For example, the Advisor may not be able to determine an overall sustainability impact score for each company based on the sustainability considerations described above because the third party service providers may not have data on the entire universe of companies considered by the Advisor for the Portfolios, or may not have information with respect to each factor listed above as a sustainability impact consideration. The sustainability impact of a company may change while the Portfolios are holding the company’s securities due to actions taken by the company or new information that becomes available concerning the company, and such information may impact the Portfolios’ decision to buy securities in the future of such company but will not necessarily result in changes to current holdings of such company. For instance, if negative information about a company becomes available, while future investment decisions should reflect that information, the Portfolios may continue to hold the securities it already owns in the short or long term, so that the composition of the Portfolios may not, at all times, reflect the most current sustainability impact considerations. The Portfolios’ exposure to companies, industries and sectors of the market may be affected by sustainability impact data obtained that may not be completely accurate with respect to any company or by a given sustainability factor that may not be as relevant as assumed in the overall score. Further, in addition to excluding or underweighting securities of corporate issuers based upon the sustainability impact considerations, the Global Sustainability Fixed Income ETF also will generally exclude or underweight securities of supranational organizations and certain non-sovereign governmental agencies (both U.S. and non-U.S.) that may be less sustainable as compared to other similar issuers, based upon the sustainability impact considerations. The Global Sustainability Fixed Income ETF’s investments in securities of U.S. and non-U.S. sovereign issuers are not subject to the sustainability impact considerations. The Advisor, however, considers securities issued by the U.S. Treasury and certain U.S. agencies and instrumentalities that are not subject to the sustainability impact considerations to be consistent with the Global Sustainability Fixed Income ETF’s strategy of investing in sustainable investments.

34

Because the Advisor takes into account sustainability impact considerations when constructing the investment portfolio, a Portfolio may not invest in, or may deviate in its exposure to, certain types of companies, industries, and segments of the designated markets in which similar portfolios without sustainability impact considerations invest.

Each Portfolios’ sustainability impact considerations are designed to meet the investing needs of shareholders; the exclusion, purchase, or sale of specific securities in a Portfolio should not be construed as reflecting a judgment by the Advisor or the Board of Trustees of the Trust relating to any sustainability issue.

PORTFOLIO TRANSACTIONS—EQUITY PORTFOLIOS

In general, securities will not be purchased or sold based on the prospects for the economy, the securities markets, or the individual issuers whose shares are eligible for purchase. Securities that have depreciated in value since their acquisition will not be sold solely because prospects for the issuer are not considered attractive or due to an expected or realized decline in securities prices in general. Securities generally will not be sold solely to realize short-term profits, but when circumstances warrant, they may be sold without regard to the length of time held. Securities, including those eligible for purchase, may be disposed of, however, at any time when, in the Advisor’s judgment, circumstances warrant their sale, including, but not limited to, tender offers, mergers, and similar transactions, or bids made for block purchases at opportune prices. Generally, securities will be purchased with the expectation that they will be held for longer than one year and will be held until such time as they are no longer an appropriate holding in light of the investment policies of each Portfolio.

In attempting to respond to adverse market, economic, political, or other considerations, the Portfolios may, from time to time, invest their assets in a temporary defensive manner that is inconsistent with the Portfolios’ principal investment strategies. In these circumstances, the Portfolios may be unable to achieve their investment objectives.

PORTFOLIO STRATEGIES—GLOBAL SUSTAINABILITY FIXED INCOME ETF

In managing the Global Sustainability Fixed Income ETF, the Advisor places priority on efficiently managing portfolio turnover and keeping trading costs low. The Portfolio will be managed with a view to capturing expected credit premiums and expected term premiums. The term “expected credit premium” means the expected incremental return on investment for holding obligations considered to have greater credit risk than direct obligations of the U.S. Treasury, and “expected term premium” means the expected relative return on investment for holding securities having longer-term maturities as compared to securities having shorter-term maturities. At times when, in the Advisor’s judgment, eligible foreign securities do not offer expected term premiums that compare favorably with those offered by eligible U.S. securities, the Portfolio will be invested primarily in the latter securities. The Advisor believes that expected credit premiums are available largely through investment in commercial paper, certificates of deposit and corporate obligations. The holding period for assets of the Portfolio will be chosen with a view to maximizing anticipated returns, net of trading costs.

In attempting to respond to adverse market, economic, political, or other conditions, the Portfolio may, from time to time, invest its assets in a temporary defensive manner that is inconsistent with the Portfolio’s principal investment strategies. In these circumstances, the Portfolio may be unable to achieve its investment objective.

ADDITIONAL INFORMATION REGARDING INVESTMENT RISKS

Because the value of your investment in a Portfolio will fluctuate, there is the risk that you will lose money. An investment in a Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description of principal risks of investing in the Portfolios.

35

Call Risk: Call risk is the risk that an issuer may exercise its right to redeem a fixed income security earlier than its maturity date. Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security that the Portfolio has invested in, the Portfolio may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

China Investments Risk: There are special risks associated with investments in China, Hong Kong and Taiwan. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite reforms and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments and on repatriation of capital invested. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. The Chinese economy is also vulnerable to the long-running disagreements with Hong Kong related to integration.

36

Investing in China A-shares through Stock Connect is subject to trading, clearance, settlement, and other procedures, which could pose risks to the Portfolio. Trading through the Stock Connect program is subject to daily quotas that limit the maximum daily net purchases on any particular day, each of which may restrict or preclude the Portfolio’s ability to invest in China A-shares through the Stock Connect program. Trading through Stock Connect may require pre-validation of cash or securities prior to acceptance of orders. This requirement may limit the Portfolio’s ability to dispose of its A-shares purchased through Stock Connect in a timely manner.

A primary feature of the Stock Connect program is the application of the home market’s laws and rules applicable to investors in China A-shares. Therefore, the Portfolio’s investments in Stock Connect China A-shares are generally subject to the securities regulations and listing rules of the People’s Republic of China (“PRC”), among other restrictions. Stock Connect can only operate when both PRC and Hong Kong markets are open for trading and when banking services are available in both markets on the corresponding settlement days. As such, the Shanghai and Shenzhen markets may be open at a time when Stock Connect is not trading, with the result that prices of China A-shares may fluctuate at times when the Portfolio is unable to add to or exit its position, which could adversely affect the Portfolio’s performance.

Changes in the operation of the Stock Connect program may restrict or otherwise affect the Portfolio’s investments or returns. Furthermore, any changes in laws, regulations and policies of the China A-shares market or rules in relation to Stock Connect may affect China A-share prices. These risks are heightened generally by the developing state of the PRC’s investment and banking systems and the uncertainty about the precise nature of the rights of equity owners and their ability to enforce such rights under Chinese law. An investment in China A-Shares is also generally subject to the risks identified under “Emerging Markets Risk,” and foreign investment risks such as price controls, expropriation of assets, confiscatory taxation, and nationalization may be heightened when investing in China. Certain investments in Chinese companies may be made through a special structure known as a VIE. In a VIE structure, foreign investors, such as the Portfolio, will only own stock in a shell company rather than directly in the VIE, which must be owned by Chinese nationals (and/or Chinese companies) to obtain the licenses and/or assets required to operate in certain restricted or prohibited sectors in China. The value of the shell company is derived from its ability to consolidate the VIE into its financials pursuant to contractual arrangements that allow the shell company to exert a degree of control over, and obtain economic benefits arising from, the VIE without formal legal ownership. While VIEs are a longstanding industry practice and are well known by Chinese officials and regulators, historically the structure has not been formally recognized under Chinese law and Chinese regulations regarding the structure are evolving. It is uncertain whether Chinese officials or regulators will withdraw their acceptance of the structure. It is also uncertain whether the contractual arrangements, which may be subject to conflicts of interest between the legal owners of the VIE and foreign investors, would be enforced by Chinese courts or arbitration bodies. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant, detrimental, and possibly permanent losses, and in turn, adversely affect the Portfolio’s returns and net asset value.

Credit Risk: Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer’s credit rating or a perceived change in an issuer’s financial strength may affect a security’s value, and thus, impact the Portfolio’s performance. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer’s right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest.

Cyber Security Risk: The Portfolio’s and its service providers’ use of internet, technology and information systems may expose the Portfolio to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the Portfolio and/or its service providers to suffer data corruption or lose operational functionality.

37

Depositary Receipts Risk: Depositary receipts, such as EDRs, GDRs and ADRs, are subject to many of the risks of the underlying securities. For some depositary receipts, the custodian or similar financial institution that holds the issuer’s shares in a trust account is located in the issuer’s home country. In these cases if the issuer’s home country does not have developed financial markets, the Portfolio could be exposed to the credit risk of the custodian or financial institution and greater market risk. In addition, the depository institution may not have physical custody of the underlying securities at all times and may charge fees for various services. The Portfolio may experience delays in receiving its dividend and interest payments or exercising rights as a shareholder. There may be an increased possibility of untimely responses to certain corporate actions of the issuer in an unsponsored depositary receipt program. Accordingly, there may be less information available regarding issuers of securities underlying unsponsored programs and there may not be a correlation between this information and the market value of the depositary receipts.

Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, foreign currency forward contracts, and swaps (collectively, “derivative instruments”), whose value is derived from that of other assets, rates or indices. Derivative instruments can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivative instruments may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Portfolio or if the cost of the derivative instrument outweighs the benefit of the hedge. The use of derivative instruments for non-hedging purposes may be considered to carry more risk than other types of investments. When the Portfolio uses derivative instruments, the Portfolio will be directly exposed to the risks of those derivatives. Derivative instruments expose the Portfolio to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty, and settlement risk (the risk faced when one party to a transaction has performed its obligations under a contract but has not yet received value from its counterparty). The possible lack of a liquid secondary market for derivative instruments and the resulting inability of the Portfolio to sell or otherwise close a derivatives position could expose the Portfolio to losses and could make derivative instruments more difficult for the Portfolio to value accurately. Some derivative instruments are more sensitive to interest rate changes and market price fluctuations than other securities. The Portfolio could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. The Advisor may not be able to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors, which could cause the Portfolio’s derivatives positions to lose value. Valuation of derivative instruments may also be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase derivative instruments or quote prices for them. Changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, securities, rate or index, and the Portfolio could lose more than the principal amount invested. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when the Portfolio is the seller of credit default swaps and counterparty risk increases when the Portfolio is a buyer of credit default swaps. In addition, where the Portfolio is the seller of credit default swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Credit default swaps may be illiquid or difficult to value.

Emerging Markets Risk: Securities of issuers associated with emerging market countries, including, but not limited to, issuers that are organized under the laws of, maintain a principal place of business in, derive significant revenues from, or issue securities backed by the government (or, its agencies or instrumentalities) of emerging market countries may be subject to higher and additional risks than securities of issuers in developed foreign markets. These risks include, but are not limited to (i) social, political and economic instability; (ii) government intervention, including policies or regulations that may restrict the Portfolio’s investment opportunities, including restrictions on investment in issuers or industries deemed sensitive to an emerging market country’s national interests; (iii) less transparent and established taxation policies; (iv) less developed legal systems allowing for enforcement of private property rights and/or redress for injuries to private property; (v) the lack of a capital market structure or market-oriented economy; (vi) higher degree of corruption and fraud; (vii) counterparties and financial institutions with less financial sophistication, creditworthiness and/or resources as those in developed foreign markets; and (viii) the possibility that the process of easing restrictions on foreign investment occurring in some emerging market countries may be slowed or reversed by unanticipated economic, political or social events in such countries, or the countries that exercise a significant influence over those

38

countries. Similar to foreign issuers, emerging market issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less publicly available financial and other information about such issuers, comparable to U.S. issuers. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Equity Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and the Portfolio that owns them, to rise or fall. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, economies and financial markets throughout the world have become increasingly interconnected, which increases the likelihood that events or conditions in one region or country will adversely affect markets or issuers in other regions or countries. Portfolio securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, regulatory events and governmental or quasi-governmental actions, among others.

The coronavirus (COVID-19) pandemic has resulted, at times, in market closures, market volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, reduced consumer demand, defaults and credit rating downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity and may heighten pre-existing political, social and economic risks, domestically or globally. The full impact and duration of the COVID-19 pandemic (or other future epidemics or pandemics) are unpredictable and may adversely affect the Portfolio’s performance.

Foreign Government Debt Risk: The risk that: (a) the governmental entity that controls the repayment of government debt may not be willing or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as political considerations, the relative size of the governmental entity’s debt position in relation to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other national economic factors; (b) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole or in part.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar).

Foreign issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less publicly available financial and other information about such issuers, comparable to U.S. issuers. Certain countries’ legal institutions, financial markets, and services are less developed than those in the U.S. or other major economies. The Portfolio may have greater difficulty voting proxies, exercising shareholder rights, securing dividends and obtaining information regarding corporate actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect to domestic issuers in U.S. courts.

Income Risk: Income risk is the risk that falling interest rates will cause the Portfolio’s income to decline because, among other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding securities.

Interest Rate Risk: Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. During periods of very low or negative interest rates, the Portfolio may be subject to a greater risk of

39

rising interest rates. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to changes in interest rates.

International Closed Market Trading Risk: To the extent that the underlying securities held by the Portfolio trade on an exchange that is closed when the securities exchange on which the Portfolio shares list and trade is open, there may be market uncertainty about the stale security pricing (i.e., the last quote from its closed foreign market) resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Large Shareholder Risk: Certain shareholders, including other funds or accounts advised by the Advisor, may from time to time own a substantial amount of the Portfolio’s shares. In addition, a third party investor, the Advisor, an authorized participant, a lead market maker, or another entity may invest in the Portfolio and hold its investment for a limited period of time solely to facilitate commencement of the Portfolio or to facilitate the Portfolio’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment. Dispositions of a large number of shares by these shareholders may adversely affect the Portfolio’s liquidity and net assets to the extent such transactions are executed directly with the Portfolio in the form of redemptions through an authorized participant, rather than executed in the secondary market. These redemptions may also force the Portfolio to sell portfolio securities when it might not otherwise do so, which may negatively impact the Portfolio’s NAV and increase the Portfolio’s brokerage costs. To the extent these large shareholders transact in shares on the secondary market, such transactions may account for a large percentage of the trading volume on listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Liquidity Risk: Liquidity risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that the Portfolio holds illiquid investments, the Portfolio’s performance may be reduced due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by the Portfolio due to low trading volume, adverse investor perceptions and/or other market developments. Liquidity risk includes the risk that the Portfolio will experience significant net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of shares of the Portfolio are concentrated in one or a few investors.

Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer- specific events will cause the value of securities, and the Portfolio that owns them, to rise or fall.

The coronavirus (COVID-19) pandemic has resulted, at times, in market closures, market volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, reduced consumer demand, defaults and credit rating downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity and may heighten pre-existing political, social and economic risks, domestically or globally. The full impact and duration of the COVID-19 pandemic (or other future epidemics or pandemics) are unpredictable and may adversely affect the Portfolio’s performance.

Market Trading Risk: Although shares of the Portfolio are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained. There are no obligations of market makers to make a market in the Portfolio’s shares or of an authorized participant to submit purchase or redemption orders for Creation Units. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the Portfolio’s portfolio securities and the Portfolio’s market price. This reduced effectiveness could result in Portfolio shares trading at a premium or discount to its NAV and also greater than normal intraday bid/ask spreads. Additionally, in stressed market conditions, the market for the Portfolio’s shares may become less liquid in response to deteriorating liquidity in the markets for the Portfolio’s portfolio holdings, which may cause a significant variance in the market price of the Portfolio’s shares and their underlying value as well as an increase in the Portfolio’s bid-ask spread.

There can be no assurance that the Portfolio’s shares will continue to trade on a stock exchange or in any market or that the Portfolio’s shares will continue to meet the requirements for listing or trading on any exchange or in any market, or that such requirements will remain unchanged. Secondary market trading in Portfolio shares may

40

be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Portfolio shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

During a “flash crash,” the market prices of the Portfolio’s shares may decline suddenly and significantly. Such a decline may not reflect the performance of the portfolio securities held by the Portfolio. Flash crashes may cause authorized participants and other market makers to limit or cease trading in the Portfolio’s shares for temporary or longer periods. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices. Shares of the Portfolio, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility associated with short selling.

Mortgage-Backed Securities Risk: Mortgage-backed securities represent interests in “pools” of mortgages and often involve risks that are different from or potentially more significant than risks associated with other types of debt instruments. Mortgage securities differ from typical debt securities in that principal is not paid back at maturity, but rather periodically over the life of the security. The Portfolio may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Portfolio because it may have to reinvest that money at the lower prevailing interest rates. As a result, mortgage securities may be less effective than some other types of debt securities as a means of securing long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. Conversely, in a period of rising interest rates, the Portfolio may exhibit additional volatility since rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making them more sensitive to changes in interest rates. As interest rates rise mortgage borrowers are less likely to exercise prepayment options, which may reduce the value of these securities and potentially cause the Portfolio to lose money. This is known as extension risk.

Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside the Advisor’s control, including instances at third parties. The Portfolio and the Advisor seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Premium/Discount Risk: Shares of the Portfolio may trade at prices other than NAV. Shares of the Portfolio trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Portfolio is calculated at the end of each business day and fluctuates with changes in the market value of the Portfolio’s holdings since the most recent calculation. The trading prices of the Portfolio’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. As a result, the trading prices of the Portfolio’s shares may deviate significantly from NAV during periods of market volatility.

Any of these factors, among others, may lead to the Portfolio’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Portfolio in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The Advisor cannot predict whether shares will trade above (premium), below (discount) or at NAV. However, because shares can be created and redeemed in Creation Units at NAV, the Advisor believes that large discounts or premiums to the NAV of the Portfolio are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Portfolio’s shares normally will trade on stock exchanges at prices close to the Portfolio’s next calculated NAV, exchange prices are not expected to correlate exactly with the Portfolio’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Portfolio that differ significantly from its NAV.

Profitability Investment Risk: High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio to at times underperform equity funds that use other investment strategies.

41

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the Portfolio may lose money and there may be a delay in recovering the loaned securities. The Portfolio could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.

Small and Mid-Cap Company Risk: Securities of small and mid-cap companies are often less liquid than those of large companies and this could make it difficult to sell a small or mid-cap company security at a desired time or price. As a result, small and mid-cap company stocks may fluctuate relatively more in price. In general, small and mid-capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources.

Sustainability Impact Consideration Investment Risk: The Portfolio’s sustainability impact considerations may limit the number of investment opportunities available to the Portfolio, and as a result, at times, the Portfolio may underperform funds that are not subject to such sustainability impact considerations. For example, the Portfolio may decline to purchase, or underweight its investment in, certain securities due to sustainability impact considerations when other investment considerations would suggest that a more significant investment in such securities would be advantageous. The Portfolio may also overweight its investment in certain securities due to sustainability impact considerations when other investment considerations would suggest that a lesser investment in such securities would be advantageous. In addition, the Portfolio may sell or retain certain securities due to sustainability impact considerations when it is otherwise disadvantageous to do so. The sustainability impact considerations may also cause the Portfolio’s industry allocation to deviate from that of funds without these considerations and of conventional benchmarks. The Advisor may also not be able to assess the sustainability impact of each company eligible for purchase by the Portfolio. For example, the Advisor may not be able to determine an overall sustainability impact score for each company based on the sustainability considerations because the third party service providers may not have data on the entire universe of companies considered by the Advisor for the Portfolio, or may not have information with respect to each factor considered as a sustainability impact consideration. Furthermore, “sustainability” is not uniformly defined, and there are significant differences in interpretations of what it means for a company to meet sustainability criteria. The Advisor’s assessment of a company’s sustainability impact may differ from assessments made by other funds, managers, or investors. As a result, there is no guarantee that the Portfolio’s investments will reflect the sustainability considerations of any particular investor.

Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. Value stocks also may underperform the market for long periods of time.

Other Information

COMMODITY POOL OPERATOR EXEMPTION

Each Portfolio is operated by a person that has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) with respect to the Portfolio, and, therefore, such person is not subject to registration or regulation as a pool operator under the CEA with respect to the Portfolio.

Securities Loans

Each Portfolio is authorized to lend securities to qualified brokers, dealers, banks and other financial institutions for the purpose of earning additional income. While a Portfolio may earn additional income from lending securities, such activity is incidental to the investment objective of the Portfolio. The value of securities loaned may not exceed 33 1/3% of the value of the Portfolio’s total assets, which includes the value of collateral received. To the extent the Portfolio loans a portion of its securities, the Portfolio will receive collateral consisting

42

generally of cash or U.S. government securities. Collateral received will be maintained by marking to market daily and (i) in an amount equal to at least 100% of the current market value of the loaned securities with respect to securities of the U.S. Government or its agencies, (ii) in an amount generally equal to 102% of the current market value of the loaned securities with respect to U.S. securities, and (iii) in an amount generally equal to 105% of the current market value of the loaned securities with respect to foreign securities. Subject to its stated investment policies, a Portfolio will generally invest the cash collateral received for the loaned securities in The DFA Short Term Investment Fund (the “Money Market Series”), an affiliated registered money market fund advised by the Advisor for which the Advisor receives a management fee of 0.05% of the average daily net assets of the Money Market Series. The securities purchased by the Money Market Series are not subject to the sustainability impact considerations that have been identified in this Prospectus. A Portfolio may also invest such collateral in securities of the U.S. Government or its agencies, repurchase agreements collateralized by securities of the U.S. Government or its agencies, and unaffiliated registered and unregistered money market funds. For purposes of this paragraph, agencies include both agency debentures and agency mortgage-backed securities.

In addition, a Portfolio will be able to terminate the loan at any time and will receive reasonable interest on the loan, as well as amounts equal to any dividends, interest or other distributions on the loaned securities. However, dividend income received from loaned securities may not be eligible to be taxed at qualified dividend income rates. See each Portfolio’s Statement of Additional Information (“SAI”) for a further discussion of the tax consequences related to securities lending. A Portfolio will be entitled to recall a loaned security in time to vote proxies or otherwise obtain rights to vote proxies of loaned securities if the Portfolio knows that a material event will occur. In the event of the bankruptcy of the borrower, a Portfolio could experience delay in recovering the loaned securities or only recover cash or a security of equivalent value. (See “Principal Risks—Securities Lending Risk” for a discussion of the risks related to securities lending).

Management of the Trust

The Advisor serves as investment advisor to each of the Portfolios. Pursuant to an Investment Management Agreement with each Portfolio, the Advisor is responsible for the management of their respective assets. The Portfolios are managed using a team approach. The investment team includes the Investment Committee of the Advisor, portfolio managers and trading personnel.

The Investment Committee is composed primarily of certain officers and directors of the Advisor who are appointed annually. As of the date of this Prospectus, the Investment Committee has fourteen members. Investment strategies for all Portfolios are set by the Investment Committee, which meets on a regular basis and also as needed to consider investment issues. The Investment Committee also sets and reviews all investment related policies and procedures and approves any changes in regards to approved countries, security types and brokers.

In accordance with the team approach used to manage the Portfolios, the portfolio managers and portfolio traders implement the policies and procedures established by the Investment Committee. The portfolio managers and portfolio traders also make daily investment decisions regarding the Portfolios based on the parameters established by the Investment Committee. The individuals named in a Portfolio’s “INVESTMENT ADVISOR/PORTFOLIO MANAGEMENT” section coordinate the efforts of all other portfolio managers or trading personnel with respect to the day to day management of such Portfolio.

The Portfolios’ SAI provides information about each portfolio manager’s compensation, other accounts managed by the portfolio manager, and the portfolio manager’s ownership of Portfolio shares.

The Advisor, and with respect to the International Portfolios and Global Sustainability Fixed Income ETF, Dimensional Fund Advisors Ltd. (“DFAL”) and DFA Australia Limited (“DFA Australia”), provide the Portfolios with a trading department and selects brokers and dealers to effect securities transactions. Securities transactions are placed with a view to obtaining best price and execution. The Advisor may pay compensation, out of the Advisor’s profits and not as an additional charge to a Portfolio, to financial intermediaries to support the sale of Portfolio shares. The Advisor’s address is 6300 Bee Cave Road, Building One, Austin, TX 78746. A discussion regarding the basis for the Board of Trustees (the “Board”) approving the Investment Management Agreements and Sub-Advisory Agreements with respect to the Portfolios will be available in a future semi-annual report for the Portfolios.

The Advisor has been engaged in the business of providing investment management services since May 1981. The Advisor is currently organized as a Delaware limited partnership and is controlled and operated by its general partner, Dimensional Holdings Inc., a Delaware corporation. The Advisor controls DFAL and DFA

44

Australia. As of January 31, 2023, assets under management for all Dimensional affiliated advisors totaled approximately $626 billion.

The Agreement and Declaration of Trust (the “Declaration”) provides that by virtue of becoming a shareholder of the Trust, each shareholder shall be held expressly to have agreed to be bound by the provisions of the Declaration. However, shareholders should be aware that they cannot waive their rights under the federal securities laws. The Declaration provides a detailed process for the bringing of derivative actions by shareholders for claims other than federal securities law claims beyond the process otherwise required by law. This derivative actions process is intended to permit legitimate inquiries and claims while avoiding the time, expense, distraction, and other harm that can be caused to a Portfolio or its shareholders as a result of spurious shareholder demands and derivative actions. Prior to bringing a derivative action, a demand by the complaining shareholder must first be made on the Trustees. The Declaration details conditions that must be met with respect to the demand. Following receipt of the demand, the Trustees must be afforded a reasonable amount of time to investigate and consider the demand. The Trustees will be entitled to retain counsel or other advisors in considering the merits of the request and shall require an undertaking by the shareholders making such request to reimburse the Trust for the expense of any such advisors in the event that the Trustees determine not to bring such action. The Trust’s process for bringing derivative suits may be more restrictive than other investment companies. The process for derivative actions for the Trust also may make it more expensive for a shareholder to bring a suit than if the shareholder was not required to follow such a process.

The Declaration also requires that actions by shareholders against a Portfolio be brought only in a certain federal court in Texas, or if not permitted to be brought in federal court, then in the Court of Chancery of the State of Delaware as required by applicable law, or the Superior Court of Delaware, (the “Exclusive Jurisdictions”) and that the right to jury trial be waived to the fullest extent permitted by law. Other investment companies may not be subject to similar restrictions. In addition, the designation of Exclusive Jurisdictions may make it more expensive for a shareholder to bring a suit than if the shareholder was permitted to select another jurisdiction. Also, the designation of Exclusive Jurisdictions and the waiver of jury trials limit a shareholder’s ability to litigate a claim in the jurisdiction and in a manner that may be more favorable to the shareholder. A court may choose not to enforce these provisions of the Declaration.

MANAGEMENT FEES

The “Annual Fund Operating Expenses“ table describes the anticipated fees to be incurred by each Portfolio for the services provided by the Advisor for the first full fiscal year. The Advisor, not the International Portfolios and Global Sustainability Fixed Income ETF, will compensate the sub-advisors.

Sub-Advisors

The Advisor has entered into Sub-Advisory Agreements with DFAL and DFA Australia, respectively, with respect to the International Portfolios and Global Sustainability Fixed Income ETF. Pursuant to the terms of each Sub-Advisory Agreement, DFAL and DFA Australia each have the authority and responsibility to select brokers or dealers to execute securities transactions for the Portfolios. Each Sub-Advisor’s duties include the maintenance of a trading desk and the determination of the best and most efficient means of executing securities transactions. At least semi-annually, the Advisor will review the holdings of each Portfolio and review the trading process and the execution of securities transactions. The Advisor is responsible for determining those securities that are eligible for purchase and sale by each Portfolio and may delegate this task, subject to its own review, to DFAL and DFA Australia. DFAL and DFA Australia maintain and furnish to the Advisor information and reports on securities of companies in certain markets, including recommendations of securities to be added to the securities that are eligible for purchase by a Portfolio, as well as making recommendations and elections on corporate actions. The Advisor controls DFAL and DFA Australia. DFA Australia has been a U.S. federally registered investment advisor since 1994 and is located at Level 43 Gateway, 1 Macquarie Place, Sydney, New South Wales 2000, Australia. DFAL has been a U.S. federally registered investment advisor since 1991 and is located at 20 Triton Street, Regent’s Place, London NW13BF, United Kingdom.

Manager of Managers Structure

The Advisor and the Trust have received an exemptive order from the Securities and Exchange Commission (the “SEC”) for a manager of managers structure that allows the Advisor to appoint, remove or change Dimensional Wholly-Owned Sub-advisors (defined below), and enter into, amend and terminate sub-advisory agreements with Dimensional Wholly-Owned Sub-advisors, without prior shareholder approval, but subject to Board approval. A “Dimensional Wholly-Owned Sub-advisor” includes (1) sub-advisors that are wholly-owned by the Advisor (i.e., an indirect or direct “wholly-owned subsidiary” (as such term is defined in the Investment Company Act of 1940 (the “1940 Act”)) of the Advisor, or (2) a sister company of the Advisor that is an indirect or direct “wholly-owned subsidiary” (as such term is defined in the 1940 Act) of the same company that, indirectly or directly, wholly owns the Advisor (“Dimensional Wholly-Owned Sub-advisors”). The Board only will approve a change with respect to sub-advisors if the Trustees conclude that such arrangements would be in the best interests of the shareholders of a Portfolio. If a new Dimensional Wholly-Owned Sub-advisor is hired for a Portfolio, shareholders will receive information about the new sub-advisor within 90 days of the change. The exemptive order allows greater flexibility for the Advisor to utilize, if desirable, personnel throughout the worldwide organization enabling a Portfolio to operate more efficiently. The Advisor will not hire unaffiliated sub-advisors without prior shareholder approval and did not request the ability to do so in its application to the SEC for an exemptive order to allow the manager of managers structure.

The use of the manager of managers structure with respect to a Portfolio is subject to certain conditions set forth in the SEC exemptive order. Under the manager of managers structure, the Advisor has the ultimate responsibility, subject to oversight by the Board, to oversee the Dimensional Wholly-Owned Sub-advisors and recommend their hiring, termination and replacement. The Advisor will provide general management services to a Portfolio, including overall supervisory responsibility for the general management and investment of the Portfolio’s assets. Subject to review and approval of the Board, the Advisor will (a) set a Portfolio’s overall investment strategies, (b) evaluate, select, and recommend Dimensional Wholly-Owned Sub-advisors to manage all or a portion of a Portfolio’s assets, and (c) implement procedures reasonably designed to ensure that Dimensional Wholly-Owned Sub-advisors comply with a Portfolio’s investment objective, policies and restrictions. Subject to review by the Board, the Advisor will (a) when appropriate, allocate and reallocate a Portfolio’s assets among multiple Dimensional Wholly-Owned Sub-advisors; and (b) monitor and evaluate the performance of Dimensional Wholly-Owned Sub-advisors.

FEE WAIVER AND EXPENSE ASSUMPTION AGREEMENTS

Pursuant to a Fee Waiver and/or Expense Assumption Agreement for each Portfolio, the Advisor has agreed to waive certain fees and in certain instances, assume certain expenses of the Portfolio, as described below. The Fee Waiver and/or Expense Assumption Agreement will remain in effect through February 28, 2024, and may only be terminated by the Trust’s Board of Trustees prior to that date. The Fee Waiver and/or Expense Assumption Agreement shall continue in effect from year to year thereafter unless terminated by the Trust or the Advisor. With respect to each Fee Waiver and/or Expense Assumption Agreement, prior year waived fees and/or assumed expenses can be recaptured only if the expense ratio following such recapture would be less than the expense cap that was in place when such prior year fees were waived and/or expenses assumed, and less than the current expense cap in place for the Portfolio. A Portfolio is not obligated to reimburse the Advisor for fees previously waived or expenses previously assumed by the Advisor more than thirty-six months before the date of such reimbursement.

The Advisor has contractually agreed to waive all or a portion of its management fee and assume the ordinary operating expenses of each of the Portfolios (excluding the expenses that the Portfolio incurs indirectly through its investment in other investment companies) (“Portfolio Expenses”) to the extent necessary to limit the Portfolio Expenses of each Portfolio, on an annualized basis, to the rates listed below as a percentage of the respective Portfolio’s average net assets (the “Expense Limitation Amount”). At any time that the Portfolio Expenses of a Portfolio are less than the Expense Limitation Amount for the Portfolio, the Advisor retains the right to recover any fees previously waived and/or expenses previously assumed to the extent that such recovery will not cause the annualized Portfolio Expenses for such Portfolio to exceed the applicable Expense Limitation Amount identified below.

46

Dividends, Capital Gains Distributions and Taxes

Dividends and Distributions. Each Portfolio intends to qualify each year as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). As a regulated investment company, a Portfolio generally pays no federal income tax on the income and gains it distributes. Dividends from net investment income are distributed quarterly by the Equity Portfolios (on a calendar basis). Dividends from net investment income are distributed monthly by the Global Sustainability Fixed Income ETF. Any net realized capital gains of the Portfolios (after any reductions for available capital loss carryforwards) are distributed annually, typically in December. A Portfolio may distribute such income dividends and capital gains more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Portfolio.

Capital gains distributions may vary considerably from year to year as a result of a Portfolio’s normal investment activities and cash flows. During a time of economic volatility, a Portfolio may experience capital losses and unrealized depreciation in value of investments, the effect of which may be to reduce or eliminate capital gains distributions for a period of time. A Portfolio may be required to distribute taxable realized gains from a prior year, even if the Portfolio has a net realized loss for the year of distribution.

Distributions may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available.

Annual Statements. Each year, you will receive a statement that shows the tax status of distributions you received the previous calendar year. Distributions declared in October, November or December to shareholders of record in such month, but paid in January, are taxable as if they were paid in December.

Avoid “Buying A Dividend.” At the time you purchase your Portfolio shares, a Portfolio’s NAV may reflect undistributed income or undistributed capital gains. A subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in a Portfolio just before it declares an income dividend or capital gains distribution is sometimes known as “buying a dividend.” In addition, a Portfolio’s NAV may, at any time, reflect net unrealized appreciation, which may result in future taxable distributions to you.

Tax Considerations. In general, if you are a taxable investor, Portfolio distributions are taxable to you as ordinary income, capital gains, or some combination of both. This is true whether you reinvest your distributions in additional Portfolio shares or receive them in cash.

For federal income tax purposes, Portfolio distributions of short-term capital gains are taxable to you at ordinary income rates. Portfolio distributions of long-term capital gains are taxable to you at long-term capital gain rates no matter how long you have owned your shares. A portfolio with a high portfolio turnover rate (a measure of how frequently assets within a portfolio are bought and sold) is more likely to generate short-term capital gains than a portfolio with a low portfolio turnover. A portion of income dividends reported by a Portfolio as qualified dividend income may be eligible for taxation by individual shareholders at long-term capital gain rates provided certain holding period requirements are met.

Compared to other types of investments, derivatives may be less tax efficient. For example, the use of derivatives by a Portfolio may cause the Portfolio to realize higher amounts of ordinary income or short-term capital gain, distributions from which are taxable to individual shareholders at ordinary income tax rates rather than at the

47

more favorable tax rates for long-term capital gains. Changes in government regulation of derivative instruments could affect the character, timing and amount of a Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy. A Portfolio’s use of derivatives also may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

If a Portfolio qualifies to pass through the tax benefits from foreign taxes it pays on its investments, and elects to do so, then any foreign taxes it pays on these investments will be treated as paid by you. You will then be entitled either to deduct your share of these taxes in computing your taxable income, or to claim a foreign tax credit for these taxes against your U.S. federal income tax (subject to limitations for certain shareholders).

Sale of Portfolio Shares. The sale of shares of a Portfolio is a taxable event and may result in a capital gain or loss to you. Currently, any capital gain or loss realized upon a sale of Portfolio shares generally is treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less. Any loss incurred on the sale or exchange of a Portfolio’s shares, held for six months or less, will be treated as a long-term capital loss to the extent of capital gain dividends received with respect to such shares. The ability to deduct capital losses may be limited.

Creation Units. An authorized participant who exchanges securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time of purchase (plus any cash received by the authorized participant as part of the issue) and the authorized participant’s aggregate basis in the securities surrendered (plus any cash paid by the authorized participant as part of the issue). An authorized participant who exchanges Creation Units for securities generally will recognize a gain or loss equal to the difference between the authorized participant’s basis in the Creation Units (plus any cash paid by the authorized participant as part of the redemption) and the aggregate market value of the securities received (plus any cash received by the authorized participant as part of the redemption). The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons exchanging securities should consult their own tax advisor with respect to whether the wash sale rules apply and when a loss might be deductible.

Under current federal tax laws, any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as a short-term capital gain or loss if the shares have been held for one year or less, assuming such Creation Unit is held as a capital asset.

If a Portfolio redeems Creation Units in cash, it may recognize more capital gains than it will if it redeems Creation Units in-kind.

Medicare Tax. An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Portfolio and net gains from redemptions or other taxable dispositions of Portfolio shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. Net investment income does not include exempt-interest dividends. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.

Backup Withholding. By law, a 24% withholding tax may apply to taxable dividends, capital gains distributions, and redemption proceeds paid to you if you do not provide your proper taxpayer identification number and certain required certifications. You may avoid this withholding requirement by providing and certifying on the account registration form your correct Taxpayer Identification Number and by certifying that you are not subject to backup withholding and are a U.S. person (including a U.S. resident alien). Withholding is also imposed if the Internal Revenue Service requires it.

State and Local Taxes. In addition to federal taxes, you may be subject to state and local taxes on distributions from a Portfolio and on gains arising on redemption or exchange of a Portfolio’s shares. Distributions of interest income and capital gains realized from certain types of U.S. Government securities may be exempt from state personal income taxes.

48

Non-U.S. Investors. Non-U.S. investors may be subject to U.S. withholding tax, at either the 30% statutory rate or a lower rate if you are a resident of a country that has a tax treaty with the U.S., and are subject to special U.S. tax certification requirements to avoid backup withholding and claim any treaty benefits. Exemptions from U.S. withholding tax are provided for certain capital gain dividends paid by a Portfolio from net long-term capital gains, exempt-interest dividends, if any, interest-related dividends paid by a Portfolio from its qualified net interest income from U.S. sources and short-term capital gain dividends, if such amounts are reported by a Portfolio. However, notwithstanding such exemptions from U.S. withholding at the source, any such dividends and distributions of income and capital gains will be subject to backup withholding at a rate of 24% if you fail to properly certify that you are not a U.S. person. Non-U.S. investors also may be subject to U.S. estate tax.

Other Reporting and Withholding Requirements. Under the Foreign Account Tax Compliance Act (“FATCA”), a 30% withholding tax is imposed on income dividends made by the Portfolio to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S. owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Portfolio shares; however, based on proposed regulations issued by the Internal Revenue Service, which may be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). Information about a Portfolio shareholder may be disclosed to the Internal Revenue Service, non-U.S. taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Portfolio fails to provide the appropriate certifications or other documentation concerning its status under FATCA.

This discussion of “DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES” is not intended or written to be used as tax advice. Because everyone’s tax situation is unique, you should consult your tax professional about federal, state, local or foreign tax consequences before making an investment in a Portfolio. Prospective investors should also consult the SAI.

Electronic Shareholder Information

In order to conserve natural resources, which the Advisor understands is an important consideration of the shareholders of the Portfolios, shareholders, when opening an account through a financial intermediary or brokerage account that provides electronic delivery, are encouraged to consent to the acceptance of all shareholder information about the Portfolio(s) in which the shareholders invest, through electronic delivery. Shareholder information includes prospectuses, statements of additional information, annual and semi-annual reports, confirmations and statements. Additionally, the Portfolios’ Web site address is https://us.dimensional.com/etfs. The current Prospectus of the Portfolios is available for viewing and printing on the Web site. An interruption in transmissions over the Internet generally or a problem in the transmission of the Portfolios’ Web site in particular could result in a delay or interruption in the ability of shareholders to access the Web site.

Purchase and Sale of Shares

Shares of a Portfolio may be acquired or redeemed directly from the Portfolio only in Creation Units or multiples thereof, as discussed in the “Creations and Redemptions” section of this Prospectus. Only an Authorized Participant (defined below) may engage in creation or redemption transactions directly with a Portfolio. An “Authorized Participant” is either a “participating party” (i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation) or a Depository Trust Company participant who, in either case, has executed an agreement with the distributor and transfer agent with respect to creations and redemptions of Creation Units. Once created, shares of a Portfolio generally trade in the secondary market in amounts less than a Creation Unit.

Shares of a Portfolio are listed for trading on a national securities exchange during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. However, there can be no guarantee that an active trading market will develop or be maintained, or that a Portfolio’s shares listing

49

will continue or remain unchanged. The Trust does not impose any minimum investment for shares of a Portfolio purchased on an exchange. Shares of the Portfolios trade under the following symbols:

Buying or selling a Portfolio’s shares on an exchange involves certain costs that may apply to all securities transactions. When buying or selling shares of a Portfolio through a financial intermediary, you may incur a brokerage commission or other charges determined by your financial intermediary. Due to these brokerage costs, if any, frequent trading may detract significantly from investment returns. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may also incur the cost of the “spread” (the difference between the bid price and the ask price). The spread varies over time for shares of a Portfolio based on its trading volume and market liquidity and is generally less if the Portfolio has more trading volume and market liquidity and more if the Portfolio has less trading volume and market liquidity. Because shares of the Portfolios trade at market price rather than NAV, an investor may pay more than NAV when purchasing shares and receive less than NAV when selling Portfolio shares. Authorized Participants may acquire Portfolio shares directly from a Portfolio, and Authorized Participants may tender their shares for redemption directly to a Portfolio, at NAV per share only in Creation Units, and in accordance with the procedures described in the SAI.

Each Portfolio’s primary listing exchange is NYSE Arca, Inc. (the “Exchange”). The Exchange is open for trading Monday through Friday and is closed on the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

The Board has not adopted a policy of monitoring for frequent purchases and redemptions of Portfolio shares (“frequent trading”) that appear to attempt to take advantage of potential arbitrage opportunities presented by a lag between a change in the value of a Portfolio’s portfolio securities after the close of the primary markets for the Portfolio’s portfolio securities and the reflection of that change in the Portfolio’s NAV (“market timing”) because each Portfolio sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under “Creations and Redemptions.” The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Portfolios are listed for trading on a national securities exchange.

SHARE PRICE

The trading prices of a Portfolio’s shares in the secondary market will fluctuate continuously throughout trading hours based on the supply of and demand for Portfolio shares and shares of underlying securities held by a Portfolio, economic conditions and other factors, rather than a Portfolio’s NAV, which is calculated at the end of each business day. Portfolio shares will trade on the Exchange at prices that may be above (i.e., at a premium) or below (i.e., at a discount), to varying degrees, the daily NAV of a Portfolio’s shares. The trading prices of a Portfolio’s shares may deviate significantly from the Portfolio’s NAV during periods of market volatility. Given, however, that a Portfolio’s shares can be issued and redeemed daily in Creation Units, the Advisor believes that large discounts and premiums to NAV should not be sustained over long periods.

The Exchange will disseminate, every fifteen seconds during the regular trading day, an indicative optimized portfolio value (“IOPV”) relating to a Portfolio. The IOPV calculations are estimates of the value of a Portfolio’s NAV per share. Premiums and discounts between the IOPV and the market price may occur. This should not be viewed as a “real-time” update of the NAV per share. The IOPV is based on the current market value of the published basket of portfolio securities and/or cash required to be deposited in exchange for a Creation Unit and does not necessarily reflect the precise composition of a Portfolio’s actual portfolio at a particular point in time. Moreover, the IOPV is generally determined by using current market quotations and/or price quotations

50

obtained from broker-dealers and other market intermediaries and valuations based on current market rates. The IOPV may not be calculated in the same manner as the NAV, which (i) is computed only once a day, (ii) unlike the calculation of the IOPV, takes into account Portfolio expenses, and (iii) may be subject, in accordance with the requirements of the 1940 Act, to fair valuation at different prices than those used in the calculations of the IOPV. The IOPV price is based on quotes and closing prices from the securities’ local market converted into U.S. dollars at the current currency rates and may not reflect events that occur subsequent to the local market’s close. Therefore, the IOPV may not reflect the best possible valuation of a Portfolio’s current portfolio. Neither the Portfolio nor the Advisor or any of their affiliates are involved in, or responsible for, the calculation or dissemination of such IOPVs and make no warranty as to their accuracy. In the future, the dissemination of the IOPV may be discontinued.

BOOK ENTRY

Shares of the Portfolios are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of, and holds legal title to, all outstanding shares of the Portfolios.

Investors owning shares of the Portfolios are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Portfolios. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

NET ASSET VALUE

The NAV per share of each Portfolio is normally calculated once daily after the close of the Exchange on which the Portfolio is listed for trading (normally, 4:00 p.m. ET) by dividing the total value of the Portfolio’s investments and other assets, less any liabilities, by the total outstanding shares of beneficial interest of the Portfolio. Note: The time at which transactions and shares are priced may be changed in case of an emergency or if the Exchange on which the Portfolio is listed for trading closes at a time other than 4:00 p.m. ET or in other situations to the extent permitted by the SEC.

The value of shares of each Portfolio will fluctuate in relation to its investment experience. Securities held by the Portfolios will be valued in accordance with applicable laws and procedures approved by the Board, and generally, as described below.

Debt securities will be valued on the basis of prices provided by one or more pricing services or other reasonably reliable sources including broker/dealers that typically handle the purchase and sale of such securities using data reflecting the earlier closing of the principal markets for those securities. Securities which are traded over-the- counter and on a stock exchange generally will be valued according to the broadest and most representative market, and it is expected that for bonds and other fixed income securities, this ordinarily will be the over-the- counter market. Net asset value includes interest on fixed income securities which is accrued daily. Generally, securities issued by open-end investment companies are valued using their respective net asset values or public offering prices, as appropriate, for purchase orders placed at the close of the NYSE.

Securities held by the Portfolios (including over-the-counter securities) are valued at, as applicable: (1) the official closing price on the exchange or market where the security is principally traded; or (2) the last reported sale price prior to that day’s close. Securities held by the Portfolios that are listed on Nasdaq are valued at the Nasdaq Official Closing Price (“NOCP”). If there is no last reported sales price or official closing price of the day, the Portfolios value the securities at the mean between the most recent quoted bid and asked prices. Price information on listed securities is taken from the exchange where the security is primarily traded. Generally, options will be valued using the same pricing methods discussed above.

51

The value of the securities and other assets of a Portfolio for which no market quotations are readily available (including restricted securities), or for which market quotations have become unreliable, are determined in good faith at fair value in accordance with Rule 2a-5 under the 1940 Act pursuant to procedures approved by the Board of the Trust. Fair value pricing also may be used if events that have a significant effect on the value of an investment (as determined in the discretion of the Advisor) occur before the NAV is calculated. When fair value pricing is used, the prices of securities used by a Portfolio may differ from the quoted or published prices for the same securities on their primary markets or exchanges.

To the extent that the Portfolios hold large numbers of securities, it is likely that it will have a larger number of securities that may be deemed illiquid and therefore must be valued pursuant to fair value pricing procedures approved by the Board than would a fund that holds a smaller number of securities. Portfolios that invest in small capitalization companies are more likely to hold illiquid securities than would a fund that invests in larger capitalization companies.

Valuing securities at fair value involves greater reliance on judgment than valuing securities that have readily available market quotations. There can be no assurance that a Portfolio could obtain the fair value assigned to a security if it were to sell the security at approximately the time at which the Portfolio determines its NAV per share. As a result, the sale or redemption by a Portfolio of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

For the International Portfolios and Global Sustainability Fixed Income ETF, the prices of securities traded in foreign currencies will be expressed in U.S. dollars by using the mid-rate prices for the U.S. dollar as quoted by generally recognized reliable sources at 4 p.m. London time. Because the International Portfolios own securities that are primarily traded in foreign markets which may trade on days when the Portfolios do not price their shares, the NAVs of the Portfolios may change on days when shareholders will not be able to purchase or redeem shares.

Certain of the securities holdings of the Emerging Markets Sustainability ETF in Approved Markets may be subject to tax, investment and currency repatriation regulations of the Approved Markets that could have a material effect on the values of the securities. For example, a Portfolio might be subject to different levels of taxation on current income and realized gains depending upon the holding period of the securities. In general, a longer holding period (e.g., 5 years) may result in the imposition of lower tax rates than a shorter holding period (e.g., 1 year). The Emerging Markets Sustainability ETF may also be subject to certain contractual arrangements with investment authorities in an Approved Market which require a Portfolio to maintain minimum holding periods or to limit the extent of repatriation of income and realized gains.

Futures contracts are valued using the settlement price established each day on the exchange on which they are traded. The value of such futures contracts held by a Portfolio is determined each day as of such close. In the absence of prices that are readily available as defined in Rule 2a-5, the futures contract will be valued in good faith at fair value in accordance with procedures approved by the Board.

Swap agreements will be valued at the price provided by an independent third-party pricing service or source. If a price is not readily available as defined in Rule 2a-5, the swap agreement will be valued in good faith at fair value in accordance with procedures approved by the Board.

Each Portfolio generally calculates its NAV per share and accepts purchase and redemption orders of Creation Units on days that the Exchange on which the Portfolio is listed for trading is open for trading.

Creations and Redemptions

Prior to trading in the secondary market, shares of a Portfolio are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of the following number of shares, or multiples thereof:

52

All orders to purchase Creation Units must be placed by or through an “Authorized Participant” that has entered into an authorized participant agreement (an “AP Agreement”) with the Portfolios’ distributor (the “Distributor”).

A creation transaction for an Equity Portfolio, which is subject to acceptance by the Distributor or its agents, generally takes place when an Authorized Participant deposits into an Equity Portfolio a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by an Equity Portfolio and a specified amount of cash. A creation transaction for the Global Sustainability Fixed Income ETF, which is subject to acceptance by the Distributor or its agents, generally takes place when an Authorized Participant deposits into the Portfolio a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Global Sustainability Fixed Income ETF and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by a Portfolio.

For the Global Sustainability Fixed Income ETF, the Trust reserves the right to permit or require that creations and redemptions of Shares be effected entirely in cash, in-kind or a combination thereof. Creation Unit transactions conducted in exchange for cash only may cause the Portfolio to recognize capital gains and to pay out higher annual capital gain distributions to shareholders than if such transactions had been conducted in-kind. Conducting Creation Unit transactions in cash may also cause the Portfolio’s shares to trade in the secondary market at wider bid-ask spreads or greater premiums or discounts to the Portfolio’s NAV.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the AP Agreement.

Only an Authorized Participant may create or redeem Creation Units directly with a Portfolio. In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to a Portfolio’s instructions or may not be executed at all, or a Portfolio may not be able to place or change orders.

When a Portfolio engages in in-kind transactions, the Portfolio intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and, in either case, has executed an AP Agreement with the Distributor. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Portfolios’ SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of a Portfolio a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus

53

delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Premium/Discount Information

Information showing the number of days the market price of a Portfolio’s shares was greater than the Portfolio’s NAV and the number of days it was less than the Portfolio’s NAV (i.e., premium or discount) for various time periods is available by visiting the Portfolio’s website at https://us.dimensional.com/etfs.

Disclosure of Portfolio Holdings

A description of the Trust’s policies and procedures regarding the release of portfolio holdings information is also available in the Trust’s SAI. Portfolio holdings information is available by visiting a Portfolio’s website at https://us.dimensional.com/etfs.

Delivery of Shareholder Documents

To eliminate duplicate mailings and reduce expenses, certain broker-dealers may deliver a single copy of certain shareholder documents, such as this Prospectus and annual and semi-annual reports, to related shareholders at the same address, even if accounts are registered in different names. This practice is known as “householding.” You may contact your broker-dealer to enroll in householding. Once enrolled, this process will continue indefinitely unless you instruct your broker-dealer otherwise. If you do not want the mailings of these documents to be combined with those of other members of your household, please contact your broker-dealer. At any time you may view current prospectuses and financial reports on a Portfolio’s website at https://us.dimensional.com/etfs.

Distribution

The Distributor or its agents distribute Creation Units for the Portfolios on an agency basis. The Distributor does not maintain a secondary market in shares of the Portfolios.

DISTRIBUTION AND SERVICE (12B-1) FEES

The Board has adopted a distribution plan, sometimes known as a Rule 12b-1 plan, that allows a Portfolio to pay distribution fees of up to 0.25% per year, to those who sell and distribute Portfolio shares and provide other services to shareholders. However, the Board has determined not to authorize payment of a Rule 12b-1 plan fee at this time. Because these fees are paid out of a Portfolio’s assets on an ongoing basis, to the extent that a fee is authorized, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.
