“Portfolio”) is to achieve long-term capital appreciation. Fees and Expenses of the Portfolio This table describes the fees and expenses you may pay if you buy, hold or sell ETF Class shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling the ETF Class shares of the Portfolio, which are not reflected in the table or Example that follows. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0010 0.0006 0.0016 -0.0002 0.0014 EXAMPLE This Example is meant to help you compare the cost of investing in the Portfolio's ETF Class shares with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Portfolio's ETF Class shares for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio's ETF Class shares reflect the net expenses of the Portfolio's ETF Class shares that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be: 14 14 50 50 88 88 88 203 203 203 PORTFOLIO TURNOVER A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 12% of the average value of its investment portfolio. 0.12 Principal Investment Strategies To achieve the U.S. Large Cap Equity Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Large Cap Equity Portfolio is designed to purchase a broad and diverse group of readily marketable equity securities of U.S. companies that the Advisor determines to be large capitalization companies within the U.S. Universe. A company’s market capitalization is the number of its shares outstanding times its price per share. The Advisor generally defines the U.S. Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the U.S. Universe it represents) of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers large cap companies to be companies whose market capitalizations are generally in the highest 90% of total market capitalization within the U.S. Universe or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company within the U.S. Universe, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible operating companies within the U.S. Universe. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a large cap company would be $17,171 million or above. This threshold will change due to market conditions. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in equity securities of large cap U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor.The Advisor may overweight certain securities, including smaller companies, lower relative price stocks, and/or higher profitability stocks within the large cap segment of the U.S. Universe. 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 increase or reduce the U.S. Large Cap Equity Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum and short-run reversals. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Large Cap Equity Portfolio 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 U.S. Large Cap Equity Portfolio may lend its portfolio securities to generate additional income.The U.S. Large Cap Equity Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x15x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. 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 a fund to at times underperform equity funds that use other investment strategies. Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund 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. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Performance The bar chart and table immediately following illustrate the variability of the Portfolio’s returns and are meant to provide some indication of the risks of investing in the Portfolio.

A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 12% of the average value of its investment portfolio. 0.12 Principal Investment Strategies To achieve the U.S. Small Cap Value Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions.

A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations.The U.S. Small Cap Value Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small-cap value segment of the U.S. market. 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.

The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers small cap companies to be companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a small cap company would be below $17,171 million. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Small Cap Value Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Small Cap Value Portfolio 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 U.S. Small Cap Value Portfolio may lend its portfolio securities to generate additional income.The U.S. Small Cap Value Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x25x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. Small Company Risk: Securities of small companies are often less liquid than those of large companies and this could make it difficult to sell a small company security at a desired time or price. As a result, small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources. Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund 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. 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 a fund to at times underperform equity funds that use other investment strategies.

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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes.

Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Fees and Expenses of the Portfolio This table describes the fees and expenses you may pay if you buy, hold or sell ETF Class shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling the ETF Class shares of the Portfolio, which are not reflected in the table or Example that follows.

The Example assumes that you invest $10,000 in the Portfolio's ETF Class shares for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio's ETF Class shares reflect the net expenses of the Portfolio's ETF Class shares that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be: 30 30 102 102 181 181 181 414 414 414 PORTFOLIO TURNOVER A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the portfolio turnover rate was 7% of the average value of its investment portfolio. 0.07 Principal Investment Strategies To achieve the U.S. Targeted Value Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Targeted Value Portfolio, using a market capitalization weighted approach, is designed to purchase a broad and diverse group of the readily marketable securities of U.S. small and mid-cap companies that the Advisor determines to be lower relative price stocks with higher profitability. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. The Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small-and mid-cap value segment of the U.S. market. 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.As a non-fundamental policy, under normal circumstances, the U.S. Targeted Value Portfolio will invest at least 80% of its net assets in securities of U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, the Advisor considers for investment companies whose market capitalizations are generally smaller than the 500th largest U.S. company. As of October 31, 2025, companies smaller than the 500th largest U.S. company fall in the lowest 10% of total U.S. market capitalization. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Based on market capitalization data as of October 31, 2025, the market capitalization of a company smaller than the 500th largest U.S. company would be below $14,941 million. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Targeted Value Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Targeted Value Portfolio 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 U.S. Targeted Value Portfolio may lend its portfolio securities to generate additional income.The U.S. Targeted Value Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x35x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. 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. Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund 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. 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 a fund to at times underperform equity funds that use other investment strategies. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Core Equity 1 Portfolio is designed to purchase a broad and diverse group of equity securities within a market capitalization weighted universe (e.g., the larger the company, the greater the proportion of the universe it represents) of U.S. companies (the “U.S. Universe”). The Portfolio invests in companies of all sizes, with moderately increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe. The Portfolio’s moderately 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. 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.As a non-fundamental policy, under normal circumstances, U.S. Core Equity 1 Portfolio will invest at least 80% of its net assets in equity securities of U.S. companies.

In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Core Equity 2 Portfolio also 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 U.S. Core Equity 2 Portfolio may lend its portfolio securities to generate additional income.The U.S. Core Equity 2 Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x55x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. 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. 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 a fund to at times underperform equity funds that use other investment strategies. Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund 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. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Performance The bar chart and table immediately following illustrate the variability of the Portfolio’s returns and are meant to provide some indication of the risks of investing in the Portfolio.

Fees and Expenses of the Portfolio This table describes the fees and expenses you may pay if you buy, hold or sell ETF Class shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling the ETF Class shares of the Portfolio, which are not reflected in the table or Example that follows. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0020 0.0006 0.0026 -0.0002 0.0024 EXAMPLE This Example is meant to help you compare the cost of investing in the Portfolio's ETF Class shares with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Portfolio's ETF Class shares for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio's ETF Class shares reflect the net expenses of the Portfolio's ETF Class shares that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be: 25 25 82 82 144 144 144 329 329 329 PORTFOLIO TURNOVER A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 11% of the average value of its investment portfolio. 0.11 Principal Investment Strategies To achieve the U.S. Vector Equity Portfolio’s investment objective, Dimensional Fund Advisors LP (the “Advisor”) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Vector Equity Portfolio is designed to purchase a broad and diverse group of equity securities within a market capitalization weighted universe (e.g., the larger the company, the greater the proportion of the universe it represents) of U.S. operating companies (the “U.S. Universe”). The Portfolio invests in companies of all sizes, with strongly increased exposure to smaller capitalization, lower relative price and higher profitability companies as compared to their representation in the U.S. Universe. The Portfolio’s strongly 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 or by avoiding purchases in that segment of the market. 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.As a non-fundamental policy, under normal circumstances, the U.S. Vector Equity Portfolio will invest at least 80% of its net assets in equity securities of U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor.The Advisor may also increase or reduce the U.S. Vector Equity Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Vector Equity Portfolio also 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 U.S. Vector Equity Portfolio may lend its portfolio securities to generate additional income.The U.S. Vector Equity Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x65x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 6% of the average value of its investment portfolio. 0.06 Principal Investment Strategies To achieve the U.S. Small Cap Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Small Cap Portfolio, using a market capitalization weighted approach, is designed to purchase a broad and diverse group of readily marketable securities of U.S. small cap companies. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. The Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small-cap segment of the U.S. market. 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.As a non-fundamental policy, under normal circumstances, the U.S. Small Cap Portfolio will invest at least 80% of its net assets in securities of small cap U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers small cap companies to be companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a small cap company would be below $17,171 million. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Small Cap Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Small Cap Portfolio 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 U.S. Small Cap Portfolio may lend its portfolio securities to generate additional income.The U.S. Small Cap Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x75x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

Fees and Expenses of the Portfolio This table describes the fees and expenses you may pay if you buy, hold or sell ETF Class shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling the ETF Class shares of the Portfolio, which are not reflected in the table or Example that follows. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0038 0.0005 0.0043 -0.0002 0.0041 EXAMPLE This Example is meant to help you compare the cost of investing in the Portfolio's ETF Class shares with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Portfolio's ETF Class shares for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio's ETF Class shares reflect the net expenses of the Portfolio's ETF Class shares that result from the contractual expense waiver in the first year only.

A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 9% of the average value of its investment portfolio. 0.09 Principal Investment Strategies To achieve the U.S. Micro Cap Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Micro Cap Portfolio, using a market capitalization weighted approach, is designed to purchase a broad and diverse group of the securities of U.S. micro cap companies. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. The Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the micro-cap segment of the U.S. market. 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.As a non-fundamental policy, under normal circumstances, the U.S. Micro Cap Portfolio will invest at least 80% of its net assets in securities of U.S. micro cap companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for the purposes of the Portfolio, the Advisor considers micro cap companies to be companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a micro cap company would be below $7,001 million. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Micro Cap Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Micro Cap Portfolio 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 U.S. Micro Cap Portfolio may lend its portfolio securities to generate additional income.The U.S. Micro Cap Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x85x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. Small Company Risk: Securities of small companies are often less liquid than those of large companies and this could make it difficult to sell a small company security at a desired time or price. As a result, small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources. 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 a fund to at times underperform equity funds that use other investment strategies. Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund 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. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 13% of the average value of its investment portfolio. 0.13 Principal Investment Strategies To achieve the U.S. High Relative Profitability Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. High Relative Profitability Portfolio is designed to purchase a broad and diverse group of readily marketable securities of large U.S. companies that the Advisor determines to have high profitability relative to other U.S. large cap companies at the time of purchase. 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 Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the large-cap high profitability segment of the U.S. market. The Portfolio’s increased exposure to such stocks may be achieved by overweighting and/or underweighting eligible stocks based on their market capitalization, relative price, and/or profitability characteristics. 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. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time.As a non-fundamental policy, under normal circumstances, the U.S. High Relative Profitability Portfolio will invest at least 80% of its net assets in securities of U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers large cap companies to be companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a large cap company would be $17,171 million or above. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. High Relative Profitability Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum and short-run reversals. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. High Relative Profitability Portfolio 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 may invest in exchange-traded funds (ETFs) for the purpose of gaining exposure to the U.S. stock market while maintaining liquidity.The U.S. High Relative Profitability Portfolio may lend its portfolio securities to generate additional income.The U.S. High Relative Profitability Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x95x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

The Portfolio will principally invest in equity securities of companies in certain real estate investment trusts (“REITs”) and companies engaged in residential construction and firms, except partnerships, whose principal business is to develop commercial property. The Portfolio invests in companies of all sizes. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. The Advisor may adjust the representation in the Portfolio of an eligible company, or exclude a company, after considering such factors as free float, price momentum, short-run reversals, trading strategies, liquidity, size, relative price, profitability, and other factors that the Advisor determines to be appropriate. 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.As a non-fundamental policy, under normal circumstances, at least 80% of the DFA Real Estate Securities Portfolio’s net assets will be invested in securities of companies in the real estate industry. The Portfolio concentrates (i.e., invests more than 25% of its net assets) its investments in securities of companies in the real estate industry. The Portfolio generally considers a company to be principally engaged in the real estate industry if the company (i) derives at least 50% of its revenue or profits from the ownership, management, development, construction, or sale of residential, commercial, industrial, or other real estate; (ii) has at least 50% of the value of its assets invested in residential, commercial, industrial, or other real estate; or (iii) is organized as a REIT or REIT-like entity. REITs and REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests. The Portfolio will make equity investments in securities listed on a securities exchange in the United States that is deemed appropriate by the Advisor.The DFA Real Estate Securities Portfolio 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 DFA Real Estate Securities Portfolio may lend its portfolio securities to generate additional income.The DFA Real Estate Securities Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x105x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. 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. Risks of Concentrating in the Real Estate Industry: A fund that concentrates (i.e., invests more than 25% of its net assets) its investments in securities of companies in the real estate industry will be exposed to the general risks of direct real estate ownership. The value of securities in the real estate industry can be affected by changes in real estate values and rental income, property taxes, and tax and regulatory requirements. Also, the value of securities in the real estate industry may decline with changes in interest rates. Investing in REITs and REIT-like entities involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject to heavy cash flow dependency and self-liquidation. REITs and REIT-like entities also are subject to the possibility of failing to qualify for tax free pass-through of income. Also, because REITs and REIT-like entities typically are invested in a limited number of projects or in a particular market segment, these entities are more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments. The performance of a fund may be materially different from the broad equity market. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Performance The bar chart and table immediately following illustrate the variability of the Portfolio’s returns and are meant to provide some indication of the risks of investing in the Portfolio.

Fees and Expenses of the Portfolio This table describes the fees and expenses you may pay if you buy, hold or sell ETF Class shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling the ETF Class shares of the Portfolio, which are not reflected in the table or Example that follows. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0015 0.0006 0.0021 -0.0003 0.0018 EXAMPLE This Example is meant to help you compare the cost of investing in the Portfolio's ETF Class shares with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Portfolio's ETF Class shares for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. The costs for the Portfolio's ETF Class shares reflect the net expenses of the Portfolio's ETF Class shares that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be: 18 18 65 65 115 115 115 265 265 265 PORTFOLIO TURNOVER A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended October 31, 2024, the Portfolio's portfolio turnover rate was 11% of the average value of its investment portfolio. 0.11 Principal Investment Strategies To achieve the U.S. Large Cap Growth Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.The U.S. Large Cap Growth Portfolio is designed to purchase a broad and diverse group of readily marketable securities of large U.S. companies that the Advisor determines to have high profitability and high relative prices compared to other U.S. large cap companies at the time of purchase. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. Securities are considered higher relative price (growth) stocks primarily because a company’s shares have a high price in relation to their book value (a “price to book ratio”) when compared with other U.S. large cap companies. The Advisor may overweight certain stocks, including smaller companies, lower relative price (value) stocks, and/or higher profitability stocks within the large-cap growth segment of the U.S. market. 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 or profitability are subject to change from time to time.As a non-fundamental policy, under normal circumstances, the U.S. Large Cap Growth Portfolio will invest at least 80% of its net assets in securities of large cap U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers large cap companies to be companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. Under the Advisor’s market capitalization guidelines described above, based on market capitalization data as of October 31, 2025, the market capitalization of a large cap company would be $17,171 million or above. This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Large Cap Growth Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum and short-run reversals. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Large Cap Growth Portfolio 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 U.S. Large Cap Growth Portfolio may lend its portfolio securities to generate additional income.The U.S. Large Cap Growth Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x115x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

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.As a non-fundamental policy, under normal circumstances, the U.S. Small Cap Growth Portfolio will invest at least 80% of its net assets in securities of small cap U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor.

This threshold will change due to market conditions.The Advisor may also increase or reduce the U.S. Small Cap Growth Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.The U.S. Small Cap Growth Portfolio 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 U.S. Small Cap Growth Portfolio may lend its portfolio securities to generate additional income.The U.S. Small Cap Growth Portfolio's ETF Class operates as an actively managed exchange-traded fund ("ETF") and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than passively managed index ETFs. <a href="" id="x125x2"></a>Principal RisksBecause the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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 Portfolio. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the 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. 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 a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices. Small Company Risk: Securities of small companies are often less liquid than those of large companies and this could make it difficult to sell a small company security at a desired time or price. As a result, small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources. Growth Investment Risk: Growth 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. 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 a fund to at times underperform equity funds that use other investment strategies. Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested. 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, a fund may lose money and there may be a delay in recovering the loaned securities. A fund 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. 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 a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks. Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund 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 fund and/or its service providers to suffer data corruption or lose operational functionality.The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange. Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread. Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Performance The bar chart and table immediately following illustrate the variability of the Portfolio’s returns and are meant to provide some indication of the risks of investing in the Portfolio. The ETF Class shares of the Portfolio are a new class of shares for which performance information is not available, and therefore, for periods prior to the inception of the ETF Class shares, the bar chart and table show performance information for the Institutional Class shares of the Portfolio, a mutual fund class of shares of the Portfolio not offered in this Prospectus. Returns of the ETF Class shares of the Portfolio may vary from the returns of the Institutional Class shares due to differences in expenses. The bar chart shows the changes in performance of the Institutional Class shares of the Portfolio from year to year. The table illustrates how annualized returns of the Institutional Class shares of the Portfolio for certain periods, both before and after taxes, compare with those of a broad measure of market performance. The table also includes the performance of an additional index with a similar investment universe as the Portfolio. The Portfolio’s past performance (before and after taxes) is not an indication of future results. Updated performance information for the Portfolio can be obtained by visiting https://www.dimensional.com/us-en/funds.The after-tax returns presented in the table for the Portfolio are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown in the table. In addition, the after-tax returns shown are not relevant to investors who hold shares of the Portfolio through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.
