&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \* &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Dimensional Fund Advisors LP (the "Advisor") has agreed to waive certain fees of the Portfolio. The Fee Waiver Agreement for the Portfolio will remain in effect through February 28, 2024, and may only be terminated by the Fund's Board of Directors prior to that date. The Advisor retains the right to seek reimbursement for any fees previously waived up to thirty-six months after such fee waiver.

**EXAMPLE**

This Example is meant to help you compare the cost of investing in the 60/40 Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio 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 reflect the net expenses of the Portfolio that result from the contractual expense waiver in

**PORTFOLIO TURNOVER**

A mutual 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 mutual fund shares are held in a taxable account. The 60/40 Portfolio does not pay transaction costs when buying and selling shares of other mutual funds managed by the Advisor (the "Underlying Funds"); however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolio. The transaction costs incurred by the Underlying Funds, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 30% based on the weighted average portfolio turnover ratios of each of the Portfolio's underlying investments.

Principal Investment Strategies

The 60/40 Portfolio is a "fund of funds", which means that the Portfolio generally allocates its assets among other funds managed by the Advisor, although it has the ability to invest directly in securities and derivatives. The Portfolio allocates its assets to Underlying Funds that invest in equity and fixed income securities. To achieve the Portfolio's and the Underlying Funds' investment objectives, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio's and the Underlying Funds' designs emphasize 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.

Generally, the Portfolio invests its assets in domestic and international equity Underlying Funds and fixed income Underlying Funds to achieve an allocation of approximately 40% to 80% (with a target allocation of approximately 60%) of the Portfolio's assets to domestic and international equity Underlying Funds and 20% to 60% (with a target allocation of approximately 40%) of its assets to fixed income Underlying Funds. Periodically the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations to the Underlying

Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.

In addition to its allocation strategy of providing exposure to the domestic and international equity and fixed income markets through investment in the Underlying Funds, the 60/40 Portfolio further diversifies its investment portfolio by allocating its assets among Underlying Funds that represent a variety of different asset classes. As of February 28, 2023, the Portfolio invests in: (1) domestic equity Underlying Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies of all market capitalization sizes with an emphasis on smaller capitalization, lower relative price, and higher profitability companies and a domestic equity Underlying Fund that primarily invests in publicly traded REITs; (2) international equity Underlying Funds that purchase a broad and diverse portfolio of securities of companies in developed and emerging markets of all market capitalization sizes with an emphasis on smaller capitalization, lower relative price, and higher profitability companies and an international equity Underlying Fund that primarily invests in publicly traded REITs and REIT-like entities; and (3) fixed income Underlying Funds that may purchase U.S. and foreign debt securities such as obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers, securities of domestic and foreign issuers denominated in U.S. dollars but not trading in the United States, obligations of supranational organizations and inflation-protected securities.

The Advisor may also increase or reduce the 60/40 Portfolio's and/or Underlying Funds' exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company's price momentum 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 60/40 Portfolio and each Underlying Fund may purchase or sell futures contracts and options on futures contracts, to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. Certain Underlying Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities, to hedge foreign currency risks, to hedge against fluctuations in currency exchange rates, or to transfer balances from one currency to another. Certain fixed income Underlying Funds also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Underlying Fund's total return.

Certain fixed income Underlying Funds also may purchase or sell futures contracts and options on futures contracts, to hedge interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Underlying Fund. Certain fixed income Underlying Funds may use derivatives to establish short positions for individual securities, markets, or currencies, in order to adjust the Underlying Fund's duration or to replace more traditional direct investments. Also the Portfolio and Underlying Funds may lend their portfolio securities to generate additional income.

A summary of the investment strategies and policies of the Underlying Funds in which the 60/40 Portfolio invests as of the date of this Prospectus is described in the Portfolio's Prospectus in the section entitled **"ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES—Investments in Underlying Funds."**

Principal Risks

Because the value of your investment in the 60/40 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.

***Fund of Funds Risk:*** The investment performance of the Portfolio is affected by the investment performance of the Underlying Funds in which the Portfolio invests. The ability of the Portfolio to achieve its investment objective depends on the ability of the Underlying Funds to meet their investment objectives and on the Advisor's decisions regarding the allocation of the Portfolio's assets among the Underlying Funds. The Portfolio may allocate assets to an Underlying Fund or asset class that underperforms other funds or asset classes. There can be no assurance that the investment objective of the Portfolio or any Underlying Fund will be achieved. When the Portfolio invests in Underlying Funds, investors are exposed to a proportionate share of the expenses of those Underlying Funds in addition to the expenses of the Portfolio. Through its investments in Underlying Funds, the Portfolio is subject to the risks of the Underlying Funds' investments. Certain of the risks of the Portfolio's and the Underlying Funds' investments are described below.

***Equity Market Risk:*** Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and the Portfolio or Underlying Fund that owns them, to rise or fall. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

Global Allocation 60/40 Portfolio Summary Prospectus 5<br>

------

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

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

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily available public information about the issuer.

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

***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 the Portfolio or an Underlying Fund to at times underperform equity funds that use other investment strategies.

6 Dimensional Fund Advisors<br>

------

***Value Investment Risk:*** Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio or an Underlying 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.

***Emerging Markets Risk:*** Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

***Interest Rate Risk:*** Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. During periods of very low or negative interest rates, the Portfolio or an Underlying Fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to changes in interest rates.

***Credit Risk:*** Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer's credit rating or a perceived change in an issuer's financial strength may affect a security's value, and thus, impact a fixed income Underlying Funds' performance. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer's right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g., BB+ or below by S&P or Fitch, or Ba1 or below by Moody's). Fixed income securities that are below investment grade involve high credit risk and are considered speculative. Below investment grade fixed income

securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price the fixed income Underlying Fund desires.

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

***Call Risk:*** Call risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding fixed income security before its maturity date, forcing a fixed income Underlying Fund to reinvest in fixed income securities with lower interest rates than the original obligations.

***Derivatives Risk:*** Derivatives are instruments, such as futures, and options thereon, and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Portfolio or if the cost of the derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of the Portfolio or Underlying Fund between the date a foreign currency forward contract is entered into and the date it expires. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When the Portfolio or an Underlying Fund uses derivatives, the Portfolio or Underlying Fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement, 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 the Portfolio or Underlying Fund could lose more than the principal amount invested. Additional risks are associated with the use of credit default swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when the Portfolio or Underlying Fund is the seller of credit default swaps and counterparty risk increases when the Portfolio or Underlying Fund is a buyer of credit default swaps. In addition, where the Portfolio or Underlying Fund is the seller of credit default swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Credit default swaps may be illiquid or difficult to value.

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

***Securities Lending Risk:*** Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the Underlying Funds may lose money and there may be a delay in recovering the loaned securities. The Underlying Funds could also lose money if they do 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. To the extent that the Portfolio holds securities directly and lends those securities, it will be also subject to the foregoing risks with respect to its loaned securities.

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

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

Other risks of the Underlying Funds are described in the 60/40 Portfolio's Prospectus in the section entitled **"Additional Risks of the Underlying Funds."**

SUPPLEMENT TO THE<br>SUMMARY PROSPECTUS, PROSPECTUS AND<br>STATEMENT OF ADDITIONAL INFORMATION<br>OF EACH OF THE PORTFOLIOS LISTED ABOVE

The purpose of this Supplement to the Summary Prospectus, Prospectus, and Statement of Additional Information dated February 28, 2023, as amended, of the Class R1 and/or Class R2 shares of the portfolios listed above (collectively, the "Portfolios"), each a series of DFA Investment Dimensions Group Inc. or Dimensional Investment Group Inc. (collectively, the "Funds"), is to notify shareholders that the Board of Directors of each Fund approved a Plan of Recapitalization pursuant to which Class R1 shares of the U.S. Targeted Value Portfolio and Class R2 shares of the Portfolios (collectively, the "Class R shares") will convert into Institutional Class shares of their respective Portfolios (the "Recapitalizations").

As a result of the Recapitalizations, shareholders holding Class R shares of each Portfolio will receive Institutional Class shares of the same Portfolio in exchange for their Class R shares of the Portfolio with an aggregate net asset value equal to the aggregate net asset value of the Class R shares so exchanged. Following the Recapitalizations, the Class R shares of each Portfolio will cease operations. The Institutional Class shares of each Portfolio are described in separate summary prospectuses, prospectuses, and statements of additional information. A copy of the summary prospectus describing the Institutional Class shares of each Portfolio is available online at: https://www.dimensional.com/us-en/document-center/ and will be mailed to shareholders, as applicable, following the Recapitalizations.

The Recapitalizations will occur without any action being necessary from shareholders, and shareholders will not bear any fees or expenses in connection with the Recapitalizations. The Recapitalizations are expected to occur on or about June 9, 2023 or such later date as determined by the officers of the Funds (the "Conversion Date"). It is anticipated that the Recapitalizations will be a tax-free event for shareholders of the Portfolios.

In connection with the conversion, effective at the close of market on February 28, 2023, each Portfolio's Class R shares will be closed to all new investors, except as noted below. Defined contribution plans, health savings plans, qualified tuition programs and other similar tax-advantaged plans or accounts and employer sponsored non-qualified deferred compensation plans, and their participants, where the Class R shares of a Portfolio were available to participants prior to the close of market on February 28, 2023, may continue to invest in the Class R shares of a Portfolio. Each Portfolio will not accept any additional purchases of Class R shares after the close of market on or about June 7, 2023. The Portfolios reserve the right to change this policy at any time. Of course, shareholders will continue to be able to exchange or redeem their shares in accordance with the policies in the Prospectus, as noted above.

*The date of this Supplement is February 28, 2023.*

that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment has a 5% return each year and the operating expenses remain the same. The costs for the Class R2 shares of the Portfolio reflect the net expenses 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 would be:

**PORTFOLIO TURNOVER**

A mutual 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 mutual fund shares are held in a taxable account. The 60/40 Portfolio does not pay transaction costs when buying and selling shares of other mutual funds managed by the Advisor (the "Underlying Funds"); however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolio. The transaction costs incurred by the Underlying Funds, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 30% based on the weighted average portfolio turnover ratios of each of the Portfolio's underlying investments.

Principal Investment Strategies

The 60/40 Portfolio is a "fund of funds", which means that the Portfolio generally allocates its assets among other funds managed by the Advisor, although it has the ability to invest directly in securities and derivatives. The Portfolio allocates its assets to Underlying Funds that invest in equity and fixed income securities. To achieve the Portfolio's and the Underlying Funds' investment objectives, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio's and the underlying funds' designs emphasize 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.

Generally, the Portfolio invests its assets in domestic and international equity Underlying Funds and fixed income Underlying Funds to achieve an allocation of approximately 40% to 80% (with a target allocation of approximately 60%) of the Portfolio's assets to domestic and international equity Underlying Funds and 20%

Global Allocation 60/40 Portfolio Summary Prospectus 3<br>

------

to 60% (with a target allocation of approximately 40%) of its assets to fixed income Underlying Funds. Periodically the Advisor will review the allocations for the Portfolio in each Underlying Fund and may adjust allocations to the Underlying Funds or may add or remove Underlying Funds in the Portfolio without notice to shareholders.

In addition to its allocation strategy of providing exposure to the domestic and international equity and fixed income markets through investment in the Underlying Funds, the 60/40 Portfolio further diversifies its investment portfolio by allocating its assets among Underlying Funds that represent a variety of different asset classes. As of February 28, 2023, the Portfolio invests in: (1) domestic equity Underlying Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies of all market capitalization sizes with an emphasis on smaller capitalization, lower relative price, and higher profitability companies and a domestic equity Underlying Fund that primarily invests in publicly traded REITs; (2) international equity Underlying Funds that purchase a broad and diverse portfolio of securities of companies in developed and emerging markets of all market capitalization sizes with an emphasis on smaller capitalization, lower relative price, and higher profitability companies and an international equity Underlying Fund that primarily invests in publicly traded REITs and REIT-like entities; and (3) fixed income Underlying Funds that may purchase U.S. and foreign debt securities such as obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers having investment grade ratings, obligations of supranational organizations and inflation-protected securities.

The Advisor may also increase or reduce the 60/40 Portfolio's and/or Underlying Funds' exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company's price momentum 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 60/40 Portfolio and each Underlying Fund may purchase or sell futures contracts and options on futures contracts, to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Portfolio or Underlying Fund. Certain Underlying Funds may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities, to hedge foreign currency risks, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. Certain fixed income Underlying Funds also may enter into credit default swaps on issuers or indices to buy or sell credit

protection to hedge credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Underlying Fund's total return. Certain fixed income Underlying Funds also may purchase or sell futures contracts and options on futures contracts, to hedge interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure, including adjustments based on actual or expected cash inflows to or outflows from the Underlying Fund. Certain fixed income Underlying Funds may use derivatives to establish short positions for individual securities, markets, or currencies, in order to adjust the Underlying Fund's duration or to replace more traditional direct investments. The Portfolio and Underlying Funds may lend their portfolio securities to generate additional income.

A summary of the investment strategies and policies of the Underlying Funds in which the 60/40 Portfolio invests as of the date of this Prospectus is described in the Portfolio's Prospectus in the section entitled **"ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES-ALLOCATION PORTFOLIOS-Investments in Underlying Funds."**

Principal Risks

Because the value of your investment in the 60/40 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.

***Fund of Funds Risk:*** The investment performance of the Portfolio is affected by the investment performance of the Underlying Funds in which the Portfolio invests. The ability of the Portfolio to achieve its investment objective depends on the ability of the Underlying Funds to meet their investment objectives and on the Advisor's decisions regarding the allocation of the Portfolio's assets among the Underlying Funds. The Portfolio may allocate assets to an Underlying Fund or asset class that underperforms other funds or asset classes. There can be no assurance that the investment objective of the Portfolio or any Underlying Fund will be achieved. When the Portfolio invests in Underlying Funds, investors are exposed to a proportionate share of the expenses of those Underlying Funds in addition to the expenses of the Portfolio. Through its investments in Underlying Funds, the Portfolio is subject to the risks of the Underlying Funds' investments. Certain of the risks of the Portfolio's and Underlying Funds' investments are described below.

***Equity Market Risk:*** Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and the Underlying Funds that own them, to rise or fall. Stock markets tend to move in cycles with periods of rising prices and periods of falling prices.

Global Allocation 60/40 Portfolio Summary Prospectus 5<br>

------

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

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

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Depositary receipts that are not sponsored by the issuer may be less liquid and there may be less readily available public information about the issuer.

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

***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 the Portfolio or an Underlying Fund to at times underperform equity funds that use other investment strategies.

6 Dimensional Fund Advisors<br>

------

***Value Investment Risk:*** Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio or an Underlying 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.

***Emerging Markets Risk:*** Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

***Interest Rate Risk:*** Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. During periods of very low or negative interest rates, the Portfolio or an Underlying Fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to changes in interest rates.

***Credit Risk:*** Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer's credit rating or a perceived change in an issuer's financial strength may affect a security's value, and thus, impact a fixed income Underlying Funds' performance. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer's right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest. Credit risk is greater for fixed income securities with ratings below investment grade (e.g., BB+ or below by S&P Global Ratings ("S&P") or Fitch Ratings Ltd. ("Fitch"), or Ba1 or below by Moody's Investor's Service, Inc. ("Moody's")). Fixed income securities that are below investment grade involve high

Global Allocation 60/40 Portfolio Summary Prospectus 7<br>

------

credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price the Portfolio desires.

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

***Call Risk:*** Call risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding fixed income security before its maturity date, forcing the Portfolio to reinvest in fixed income securities with lower interest rates than the original obligations.

***Derivatives Risk:*** Derivatives are instruments, such as futures, and options thereon, and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Portfolio or if the cost of the derivative outweighs the benefit of the hedge. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of the Portfolio or Underlying Fund between the date a foreign currency forward contract is entered into and the date it expires. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When the Portfolio or an Underlying Fund uses derivatives, the Portfolio or Underlying Fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement, 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 the Portfolio or Underlying Fund could lose more than the principal amount invested. Additional risks are associated with the use of credit default swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when the Portfolio is the seller of credit default swaps and counterparty risk increases when the Portfolio is a buyer of credit default swaps. In addition, where the Portfolio is the seller of credit default swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Credit default swaps may be illiquid or difficult to value.

***Securities Lending Risk:*** Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the Underlying Funds may lose money and there may be a delay in recovering the loaned securities. The Underlying Funds could also lose money if they do 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. To the extent that the Portfolio holds securities directly and lends those securities, it will be also subject to the foregoing risks with respect to its loaned securities.

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

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

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

Other risks of the Underlying Funds are described in the Portfolio's Prospectus in the section entitled **"ADDITIONAL INFORMATION ON INVESTMENT OBJECTIVES AND POLICIES—ALLOCATION PORTFOLIOS."**
