Annual Fund Operating Expenses (expenses that you pay each
year as a percentage of the value of your investment)*

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. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the World ex U.S. Targeted Value Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 35% of the average value of its investment portfolio.

The bar chart and table immediately following illustrate the variability of the World ex U.S. Targeted Value Portfolio’s returns and are meant to provide some indication of the risks of investing in the Portfolio. The bar chart shows the changes in the Portfolio’s performance from year to year. The table illustrates how annualized one year, five year and ten year returns, both before and after taxes, compare with those of a broad measure of market performance. The Portfolio’s past performance (before and after taxes) is not an indication of future results.

Dimensional Fund Advisors LP serves as the investment advisor for the World ex U.S. Targeted Value Portfolio. Dimensional Fund Advisors Ltd. and DFA Australia Limited serve as the sub-advisors for the Portfolio. The following individuals are responsible for leading the day to day management of the Portfolio:

Investors may purchase or redeem shares of the World ex U.S. Targeted Value Portfolio on each day that the NYSE is scheduled to be open for business by first contacting the Portfolio’s transfer agent at (888) 576-1167. Shareholders that invest in the Portfolio through a financial intermediary should contact their financial intermediary regarding purchase and redemption procedures. The Portfolio generally is available for investment only by institutional clients, clients of registered investment advisors, clients of financial institutions and a limited number of certain other investors as approved from time to time by the Advisor. All investments are subject to approval of the Advisor.

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as a 401(k) plan or an individual retirement account, in which case distributions may be taxed as ordinary income when withdrawn from the plan or account.

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

The investment company described in this Prospectus offers a variety of investment portfolios. Each of the investment company’s portfolios has its own investment objective and policies, and is the equivalent of a separate mutual fund. The Portfolio described in this Prospectus is designed for long-term investors.

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

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

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

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

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

The investment objective of the World ex U.S. Targeted Value Portfolio is to achieve long-term capital appreciation. The Portfolio seeks to achieve its investment objective by purchasing a broad and diverse group of mostly small and mid-sized non-U.S. companies associated with countries with developed and emerging markets, which may include frontier markets (emerging markets in an earlier stage of development), that the Advisor believes to be value stocks with higher profitability at the time of purchase and have been authorized for investment as Approved Markets by the Advisor’s Investment Committee. As of the date of this Prospectus, the following markets have been authorized for investment as Approved Markets for the World ex U.S. Targeted Value Portfolio: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Kuwait, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom, Brazil, Chile, China, Colombia, Greece, Hungary, India, Indonesia, Malaysia, Mexico, the Philippines, Poland, Qatar, Saudi Arabia, South Africa, South Korea, Taiwan, Thailand, Turkey, and the United Arab Emirates (collectively, the “Approved Markets”). The Advisor will determine in its discretion when and whether to invest in markets that have been authorized as Approved Markets, depending on a number of factors, including, but not limited to, asset growth in the Portfolio, constraints imposed in Approved Markets, and other characteristics of each such market. The Investment Committee of the Advisor also may authorize other markets for investment in the future, in addition to the Approved Markets identified above, or may remove one or more markets from the list of Approved Markets. Although the Advisor does not intend to purchase securities not associated with an Approved Market, the Portfolio may acquire such securities in connection with corporate actions or other reorganizations or transactions with respect to securities that are held by the Portfolio from time to time. Also, the Portfolio may continue to hold investments in countries that are not currently designated as Approved Markets, but had been authorized for investment in the past, and may reinvest distributions received in connection with such existing investments in such previously Approved Markets. (For a description of the securities approved for investment, see “Approved Markets”).

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

The World ex U.S. Targeted Value Portfolio intends to purchase securities of small and mid-sized companies in countries with developed and emerging markets that the Advisor believes to be value stocks with higher profitability at the time of purchase. 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 determines what constitutes a small or mid-sized company on a country- or region-specific basis and based primarily on market capitalization. The Advisor may adjust the representation in the World ex

U.S. Targeted Value Portfolio of an eligible company, or exclude a company, after considering such factors as free float, price momentum, trading strategies, liquidity, size, relative price, profitability, investment characteristics, and other factors that the Advisor determines to be appropriate.

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

The Advisor may consider a small capitalization company’s investment characteristics as compared to other eligible companies when making investment decisions and may exclude a small capitalization company with high investment as measured by the company’s recent asset growth. The Portfolio will generally not exclude more than 5% of the eligible small capitalization company universe within each country based on such investment characteristics. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. The Advisor may decrease the amount that the Portfolio invests in eligible small capitalization companies that have lower profitability and/or higher relative prices.

The World ex U.S. Targeted Value Portfolio may invest in ETFs for the purpose of gaining exposure to the equity markets, including the United States, while maintaining liquidity. The Portfolio also may purchase or sell futures contracts and options on futures contracts for equity securities and indices, including those of the United States, to adjust market exposure based on actual or expected cash inflows to or outflows from the Portfolio. In addition to money market instruments and other short-term investments, the Portfolio may invest in affiliated and unaffiliated registered and unregistered money market funds to manage the Portfolio’s cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in ETFs and money market funds may involve a duplication of certain fees and expenses.

The World ex U.S. Targeted Value Portfolio may also invest in China A-shares (equity securities of companies listed in China) that are accessible through the Shanghai-Hong Kong Stock Connect program or the Shenzhen-Hong Kong Stock Connect program (together “Stock Connect”) and variable interest entities (special structures that utilize contractual arrangements to provide exposure to certain Chinese companies).

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

The Portfolio also may obtain exposure to Approved Market Securities by investing in derivative instruments that derive their value from Approved Markets Securities, or by investing in securities of pooled investment vehicles that invest at least 80% of their assets in Approved Markets Securities.

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

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

When managing its investment portfolio, the World ex U.S. Targeted Value Portfolio intends to consider federal tax implications when making investment decisions with respect to individual securities to seek to provide a tax advantage. When selling securities, the Portfolio typically will select the highest cost shares of the specific security in order to minimize the realization of capital gains. In certain cases, the highest cost shares may produce a short-term capital gain. Since short-term capital gains generally are taxed at higher tax rates than long-term capital gains, the highest cost shares with a long-term holding period may be disposed of instead. The Portfolio, when possible, will generally refrain from disposing of a security until the long-term holding period for capital gains for tax purposes has been satisfied. Additionally, the Portfolio, when consistent with its investment and tax policies, may sell securities in order to realize capital losses. Realized capital losses can be used to offset realized capital gains, thus reducing capital gains distributions. The Advisor may delay buying the stock of a company that meets applicable investment criteria in order to avoid dividend income, and may sell the stock of a company that meets applicable investment criteria in order to realize a capital loss. Also, the Portfolio may dispose of securities whenever the Advisor determines that disposition is consistent with the Portfolio’s tax and investment management strategies or is otherwise in the best interest of the Portfolio. As part of its investment decisions, the Advisor may also consider the effects of holding periods and securities lending, among other factors, that may affect the tax characteristics of the income received.

Although the Advisor intends to manage the Portfolio in a manner that considers the effects of the realization of capital gains and taxable dividend income each year, the Portfolio may nonetheless distribute taxable gains and dividends to shareholders. Of course, realization of capital gains is not entirely within the Advisor’s control. Capital gains distributions may vary considerably from year to year. The Portfolio may be required to distribute taxable realized gains from a prior year, even if the Portfolio has a net realized loss for the year of distribution. Furthermore, the redeeming shareholders will be required to pay taxes on their capital gains, if any, on a redemption of the Portfolio’s shares, whether paid in cash or in kind, if the amount received on redemption is greater than the amount of the shareholder’s tax basis in the shares redeemed.

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. The following is a description of principal risks of investing in the Portfolio.

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

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

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

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

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.

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

Derivatives Risk: Derivatives are instruments, such as futures, and options thereon, and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. The use of derivative instruments for non-hedging purposes may be considered to carry more risk than other types of investments. When the Portfolio uses derivative instruments, the Portfolio will be directly exposed to the risks of those derivatives. Derivative instruments expose the Portfolio to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty, and settlement risk (the risk faced when one party to a transaction has performed its obligations under a contract but has not yet received value from its counterparty). The possible lack of a liquid secondary market for derivative instruments and the resulting inability of the Portfolio to sell or otherwise close a derivatives position could expose the Portfolio to losses and could make derivative instruments more difficult for the Portfolio to value accurately. Some derivative instruments are more sensitive to interest rate changes and market price fluctuations than other securities. The Portfolio could also suffer losses related to its derivatives positions as a result of unanticipated market movements, which losses are potentially unlimited. The Advisor may not be able to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors, which could cause the Portfolio’s derivatives positions to lose value. Valuation of derivative instruments may also be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase derivative instruments or quote prices for them. Changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, securities, rate or index, and the Portfolio could lose more than the principal amount invested.

Emerging Markets Risk: Securities of issuers associated with emerging market countries, including, but not limited to, issuers that are organized under the laws of, maintain a principal place of business in, derive significant revenues from, or issue securities backed by the government (or, its agencies or instrumentalities) of emerging market countries may be subject to higher and additional risks than securities of issuers in developed foreign markets. These risks include, but are not limited to (i) social, political and economic instability; (ii) government intervention, including policies or regulations that may restrict the Portfolio’s investment opportunities, including restrictions on investment in issuers or industries deemed sensitive to an emerging market country’s national interests; (iii) less transparent and established taxation policies; (iv) less developed legal systems allowing for enforcement of private property rights and/or redress for injuries to private property; (v) the lack of a capital market structure or market-oriented economy; (vi) higher degree of corruption and fraud; (vii) counterparties and financial institutions with less financial sophistication, creditworthiness and/or resources as those in developed foreign markets; and (viii) the possibility that the process of easing restrictions on foreign investment occurring in some emerging market countries may be slowed or reversed by unanticipated economic, political or social events in such countries, or the countries that exercise a significant influence over those countries. Similar to foreign issuers, emerging market issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less publicly available financial and other information about such issuers, comparable to U.S. issuers. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

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

falling prices. In addition, economies and financial markets throughout the world have become increasingly interconnected, which increases the likelihood that events or conditions in one region or country will adversely affect markets or issuers in other regions or countries. Portfolio securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, regulatory events and governmental or quasi-governmental actions, among others.

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

Foreign 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). The World ex U.S. Targeted Value Portfolio does not hedge foreign currency risk.

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

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.

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

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

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

Tax Advantage Strategy Risk: An investment strategy that considers the tax implications of investment decisions alter the management of the Portfolio and affect portfolio holdings, when compared to other mutual funds that do not take into account potential tax implications. The Advisor anticipate what performance of the Portfolio may deviate from that of mutual funds that do not take into account potential tax implications.

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

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

The Portfolio is authorized to lend securities to qualified brokers, dealers, banks and other financial institutions for the purpose of earning additional income. While the Portfolio may earn additional income from lending securities, such activity is incidental to the investment objective of the Portfolio. For information concerning the revenue from securities lending, see “SECURITIES LENDING REVENUE.” The value of securities loaned may not exceed 33¹/₃% of the value of the Portfolio’s total assets, which includes the value of collateral received. To the extent the Portfolio loans a portion of its securities, the Portfolio will receive collateral consisting generally of cash or U.S. government securities. Collateral received will be maintained by marking to market daily and (i) in an amount equal to at least 100% of the current market value of the loaned securities with respect to securities of the U.S. Government or its agencies, (ii) in an amount generally equal to 102% of the current market value of the loaned securities with respect to U.S. securities, and (iii) in an amount generally equal to 105% of the current market value of the loaned securities with respect to foreign securities. Subject to its stated investment policies, the Portfolio will generally invest the cash collateral received for the loaned securities in The DFA Short Term Investment Fund (the “Money Market Series”), an affiliated registered money market fund advised by the Advisor for which the Advisor receives a management fee of 0.05% of the average daily net assets of the Money Market Series. The Portfolio may also invest such collateral in securities of the U.S. Government or its agencies, repurchase agreements collateralized by securities of the U.S. Government or its agencies, and affiliated and unaffiliated registered and unregistered money market funds. For purposes of this paragraph, agencies include both agency debentures and agency mortgage backed securities.

In addition, the Portfolio will be able to terminate the loan at any time and will receive reasonable interest on the loan, as well as amounts equal to any dividends, interest or other distributions on the loaned securities. However, dividend income received from loaned securities may not be eligible to be taxed at qualified dividend income rates. As a result, the Portfolio may limit the use of securities lending to limit the impact of these tax consequences. See the Statement of Additional Information (“SAI”) for a further discussion of the tax consequences related to securities lending. The Portfolio will be entitled to recall a loaned security in time to vote proxies or otherwise obtain rights to vote proxies of loaned securities if the Portfolio knows a material event will occur. In the event of the bankruptcy of the borrower, DFA Investment Dimensions Group Inc. (the “Fund”) could experience delay in recovering the loaned securities or only recover cash or a security of equivalent value. See “PRINCIPAL RISKS—Securities Lending” for a discussion of the risks related to securities lending.

For the fiscal year ended October 31, 2022, the Portfolio received the following net revenues from a securities lending program, which constituted a percentage of the average daily net assets of the Portfolio (see “SECURITIES LOANS”):

The Advisor serves as investment advisor to the Portfolio. Pursuant to an Investment Management Agreement with the Fund on behalf of the Portfolio, the Advisor is responsible for the management of the Portfolio’s assets. The Portfolio is managed using a team approach. The investment team includes the Investment Committee of the Advisor, portfolio managers and trading personnel.

The Investment Committee is composed primarily of certain officers and directors of the Advisor who are appointed annually. As of the date of this Prospectus the Investment Committee has fourteen members.

The Investment Committee also sets and reviews all investment related policies and procedures and approves any changes in regards to approved countries, security types and brokers.

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

The Advisor may pay compensation, out of the Advisor’s profits and not as an additional charge to the Portfolio, to financial intermediaries to support the sale of Portfolio shares. The Advisor’s address is 6300 Bee Cave Road, Building One, Austin, TX 78746. A discussion regarding the basis for the Board of Directors approving the Investment Management Agreement and Sub-Advisory Agreements with respect to the Portfolio is available in the semi-annual report for the Portfolio for the fiscal period ending April 30, 2022.

The Fund bears all of its own fees, expenses, charges, assessments, taxes, and other costs incurred in its operations, whether incurred directly by the Fund or incurred by the Advisor on its behalf. The expenses payable by the Fund shall include, but are not limited to: services of its independent registered public accounting firm, legal counsel to the Fund and its disinterested directors, fees and expenses of disinterested directors, employees and consultants, accounting and pricing costs (including the daily calculations of net asset value), brokerage fees, commissions and transfer taxes in connection with the acquisition and disposition of portfolio securities, taxes and other governmental fees levied against the Fund, insurance premiums, investment fees and expenses of the Fund, including the interest expense of borrowing money, the costs incidental to meetings of their shareholders and directors, the cost of filing their registration statements under the federal securities laws and the cost of any other filings required under federal and state securities laws, the costs of preparing, printing and mailing proxies, shareholder reports, prospectuses, statements of additional information and other fund documents, transfer and dividend disbursing agency, administrative services and custodian fees, including the expenses of issuing, repurchasing or redeeming its shares, fees and expenses of securities lending agents and the oversight of the securities lending activities of the Fund, fees and expenses associated with trade administration oversight services with respect to reconciliations and the oversight of settlement and collateral management, litigation, regulatory examinations/proceedings and other extraordinary or nonrecurring expenses, and other expenses properly payable by the Fund. Expenses allocable to the Portfolio are so allocated. The expenses of the Fund which are not allocable to a particular portfolio are to be borne by the Portfolio on the basis of its relative net assets.

The Advisor has been engaged in the business of providing investment management services since May 1981. The Advisor is currently organized as a Delaware limited partnership and is controlled and operated by its general partner, Dimensional Holdings Inc., a Delaware corporation. The Advisor controls Dimensional Fund DFAL and DFA Australia. As of January 31, 2023, assets under management for all Dimensional affiliated advisors totaled approximately $626 billion.

The “Annual Fund Operating Expenses” table describes the management fee to be paid by the Portfolio. The effective management fee paid to the Advisor by the Portfolio, based on the Portfolio’s average daily net assets on an annualized basis, during the fiscal year ended October 31, 2022 was 0.42%, which reflects a management fee reduction that was effective as of February 28, 2022. The Advisor, not the Portfolio, compensates the sub-advisors.

The Advisor has entered into Sub-Advisory Agreements with DFAL and DFA Australia, respectively, with respect to the World ex U.S. Targeted Value Portfolio. Pursuant to the terms of the Sub-Advisory Agreement, DFAL and DFA Australia each have the authority and responsibility to select brokers or dealers to execute securities transactions for the Portfolio. Each Sub-Advisor’s duties include the maintenance of a trading desk and the determination of the best and most efficient means of executing securities transactions. On at least a semi-annual basis, the Advisor will review the holdings of the Portfolio and review the trading process and the execution of securities transactions. The Advisor is responsible for determining those securities which are eligible for purchase and sale by the Portfolio and may delegate this task, subject to its own review, to DFAL and DFA Australia. DFAL and DFA Australia maintain and furnish to the Advisor information and reports on securities of companies in certain markets, including recommendations of securities to be added to the securities that are eligible for purchase by the Portfolio, as well as making recommendations and elections on corporate actions. The Advisor controls DFAL and DFA Australia. DFA Australia has been a U.S. federally registered investment advisor since

1994 and is located at Level 43 Gateway, 1 Macquarie Place, Sydney, New South Wales 2000, Australia. DFAL has been a U.S. federally registered investment advisor since 1991 and is located at 20 Triton Street, Regent’s Place, London NW13BF, United Kingdom.

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

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

On behalf of the Portfolio, the Fund may enter into shareholder servicing agreements with financial intermediaries to provide shareholder servicing, recordkeeping, account maintenance and other services to shareholders of the Portfolio. For the array of services provided to shareholders of the Portfolio, the Fund may pay such financial intermediaries a fee for such services. These expenses will be included in “Other Expenses” in the “Annual Fund Operating Expenses” table.

Pursuant to an Amended and Restated Fee Waiver and/or Expense Assumption Agreement (the “Fee Waiver and/or Expense Assumption Agreement”) for the Portfolio, the Advisor has agreed to waive certain fees and in certain instances, assume certain expenses of the Portfolio, as described below. The Fee Waiver and/or Expense Assumption Agreement will remain in effect through February 28, 2024, and may only be terminated by the Fund’s Board of Directors prior to that date. The Fee Waiver and/or Expense Assumption Agreement shall continue in effect from year to year thereafter unless terminated by the Fund or the Advisor. With respect to the Fee Waiver and/or Expense Assumption Agreement, prior year waived fees and/or assumed expenses can be recaptured only if the expense ratio following such recapture would be less than the expense cap that was in place when such prior year fees were waived and/or expenses assumed, and less than the current expense cap in place for the Portfolio. The Advisor shall also not be reimbursed for any management fees previously waived to

offset the Portfolio’s proportionate share of the management fees paid by the Portfolio through its investment in other funds managed by the Advisor.

The Advisor has contractually agreed to waive up to the full amount of the Portfolio’s management fee of 0.40% to the extent necessary to offset the proportionate share of the management fees paid by the Portfolio through its investment in other funds managed by the Advisor, except for the fees paid through investment of securities lending cash collateral in the Money Market Series (the “Underlying Funds”). In addition, under the Fee Waiver Agreement, the Advisor has also agreed to waive all or a portion of the management fee and to assume the ordinary operating expenses of a class of the Portfolio (including expenses incurred through its investment in other investment companies but excluding the expenses that the Portfolio incurs indirectly through its investment of its securities lending cash collateral in the Money Market Series) (“Portfolio Expenses”) to the extent necessary to limit the Portfolio Expenses of a class of the Portfolio to the rate listed below as a percentage of the average net assets of a class of the Portfolio on an annualized basis (the “Expense Limitation Amount”). At any time that the Portfolio Expenses of a class of the Portfolio are less than the Expense Limitation Amount for such class of the Portfolio, the Advisor retains the right to recover any fees previously waived and/or expenses previously assumed to the extent that such recovery will not cause the annualized Portfolio Expenses of a class of the Portfolio to exceed the Expense Limitation Amount. The Portfolio is not obligated to reimburse the Advisor for fees previously waived or expenses previously assumed by the Advisor more than thirty-six months before the date of such reimbursement.

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

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

You will automatically receive all income dividends and capital gains distributions in additional shares of the Portfolio whose shares you hold at net asset value (as of the business date following the dividend record date), unless, upon written notice to the Advisor and completion of account information, you request to receive income dividends or capital gains distributions, or both, in cash.

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

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

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

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

Compared to other types of investments, derivatives may be less tax efficient. For example, the use of derivatives by the Portfolio may cause the Portfolio to realize higher amounts of ordinary income or short-term capital gain, distributions from which are taxable to individual shareholders at ordinary income tax rates rather than at the more favorable tax rates for long-term capital gains. Changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy. The Portfolio’s use of derivatives also may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

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

Sale or Redemption of Portfolio Shares. The sale of Portfolio shares is a taxable event and may result in a capital gain or loss to you. Capital gain or loss may be realized from an ordinary redemption of shares or an exchange of shares between two Portfolios. Any loss incurred on the sale or exchange of the Portfolio’s shares, held for six months or less, will be treated as a long-term capital loss to the extent of capital gain dividends received with respect to such shares.

The Portfolio is required to report to you and the Internal Revenue Service annually on Form 1099-B not only the gross proceeds of Portfolio shares you sell or redeem but also the cost basis for shares you sell or redeem that were purchased or acquired on or after January 1, 2012. Cost basis will be calculated using the Portfolio’s default method of average cost, unless you instruct the Portfolio to use a different calculation method. Shareholders should carefully review the cost basis information provided by the Portfolio and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If your account is held by your investment representative (financial advisor or other broker), please contact that representative with respect to reporting of cost basis and available elections for your account. Tax-advantaged retirement accounts will not be affected.

Medicare Tax. An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the Portfolio and net gains from redemptions or other taxable dispositions of Portfolio shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.

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

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

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

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

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

Investors who do not already have an agreement in place with the Fund may purchase Institutional Class shares of the Portfolio by first contacting the Portfolio’s transfer agent at (888) 576-1167. Investors that invest through a financial intermediary should contact such intermediary with regard to purchase instructions. The Portfolio generally is available for investment only by institutional clients, clients of registered investment advisors, clients of financial institutions, and a limited number of certain other investors, each as approved from time to time by the Advisor (“Eligible Investors”). Eligible Investors include employees, former employees, shareholders and directors of the Advisor and the Fund and friends and family members of such persons. The Portfolio generally is available for investment only to U.S. citizens, U.S. residents, and U.S. domestic corporations, partnerships, trusts, or other entities. For purposes of this limitation, U.S. citizens and U.S. residents must reside in the U.S. and U.S. domestic corporations, partnerships, trusts, and other entities must have a U.S. address of record. All investments are subject to approval of the Advisor, and all investors must complete and submit the necessary account registration forms in good order. The Fund reserves the right to reject any initial or additional investment and to suspend the offering of shares of the Portfolio.

All purchases must be received in good order. “Good order” with respect to the purchase of shares means that (1) a fully completed and properly signed Account Registration Form and any additional supporting legal documentation required by the Advisor and/or transfer agent have been received in legible form, and (2) the transfer agent has been notified of the purchase, no later than the close of regular trading on the NYSE

(normally, 4:00 p.m. ET) (“Market Close”) on the day of the purchase. It is the investor or financial intermediary’s responsibility to ensure notification is received in good order by the transfer agent prior to the Market Close on the purchase date.

Under certain conditions, the Portfolio may accept and process purchase orders after the close of the NYSE on days that the NYSE unexpectedly closes early and may accept orders on a business day that the NYSE is unexpectedly closed. All orders will be processed at the next determined net asset value per share.

Payment of the total amount due should be made in U.S. dollars. If your payment is not received on settlement date, your purchase may be canceled. If an order to purchase shares must be canceled due to nonpayment, the purchaser will be responsible for any loss incurred by the Fund arising out of such cancellation. To recover any such loss, the Fund reserves the right to redeem shares owned by any purchaser whose order is canceled, and such purchaser may be prohibited or restricted in the manner of placing further orders.

Wire. Investors having an account with a bank that is a member or a correspondent of a member of the Federal Reserve System may purchase shares by wire after providing notification to the transfer agent by an approved method. The transfer agent can be reached by phone at (888) 576-1167. Notification must include the account number, account name, Portfolio number, trade date and purchase amount. On or before settlement date, the investor paying by wire must request their bank to transmit immediately available funds (federal funds) by wire to the Fund’s custodian for the account of DFA Investment Dimensions Group Inc. (specify the Portfolio). Additional investments also may be made through the wire procedure by first notifying the transfer agent. If your payment is not received on settlement date, your purchase may be canceled.

Check. Investors who wish to purchase shares of the Portfolio by check should first call the Portfolio’s transfer agent at (888) 576-1167 for additional instructions. Checks should be made payable to Dimensional Funds. Reference the name of the Portfolio in which you wish to invest.

Shares also may be purchased and sold by individuals through securities firms that may charge a service fee or commission for such transactions. No such fee or commission is charged on shares that are purchased or redeemed directly from the Fund. Investors who are clients of investment advisory organizations may also be subject to investment advisory fees under their own arrangements with such organizations.

If accepted by the Fund, shares of the Portfolio may be purchased in exchange for securities that are eligible for acquisition by the Portfolio or otherwise represented in its portfolio as described in this Prospectus or as otherwise consistent with the Fund’s policies or procedures or in exchange for local currencies in which such securities of the Portfolio are denominated. Securities and local currencies accepted by the Fund for exchange and Fund shares to be issued in the exchange will be valued as set forth under “VALUATION OF SHARES” at the time of the next determination of net asset value after such acceptance. All dividends, interest, subscription, or other rights pertaining to such securities shall become the property of the Portfolio whose shares are being acquired and must be delivered to the Fund by the investor upon receipt from the issuer. Investors who desire to purchase shares of the Portfolio with local currencies should first contact the Advisor.

The Fund will not accept securities in exchange for shares of the Portfolio unless: (1) such securities are, at the time of the exchange, eligible to be included, or otherwise represented, in the Portfolio and current market values are available for such securities based on the Fund’s valuation procedures; (2) the investor represents and agrees that all securities offered to be exchanged are not subject to any restrictions upon their sale by the Portfolio under the Securities Act of 1933 or under the laws of the country in which the principal market for such securities exists, or otherwise; and (3) at the discretion of the Fund, the value of any such security (except U.S. government securities) being exchanged together with other securities of the same issuer owned by the Portfolio may not exceed 5% of the net assets of the Portfolio immediately after the transaction.

A gain or loss for federal income tax purposes will generally be realized by investors who are subject to federal taxation upon the exchange depending upon the cost of the securities or local currency exchanged. Investors interested in such exchanges should contact the Advisor. Purchases of shares will be made in full and fractional shares calculated to three decimal places. In the interest of economy and convenience, certificates for shares will not be issued.

The Portfolio is designed for long-term investors and is not intended for investors that engage in excessive short-term trading activity that may be harmful to the Portfolio, including but not limited to market timing. Excessive short-term trading into and out of the Portfolio can disrupt portfolio management strategies, harm performance and increase Portfolio expenses for all shareholders, including long-term shareholders who do not generate these costs.

In addition, the Portfolio may be more susceptible to the risks of short-term trading than other portfolios. The nature of the Portfolio’s holdings may present opportunities for a shareholder to engage in a short-term trading strategy that exploits possible delays between changes in the price of the Portfolio’s holdings and the reflection of those changes in the Portfolio’s net asset value (called “arbitrage market timing”). Such delays may occur because the Portfolio has significant investments in foreign securities where, due to time zone differences, the values of those securities are established some time before the Portfolio calculates its net asset value. In such circumstances, the available market prices for such foreign securities may not accurately reflect the latest indications of value at the time the Portfolio calculates its net asset value. The Portfolio also may be subject to arbitrage market timing because it has significant holdings in small cap securities, which may have prices that do not accurately reflect the latest indications of value of these securities at the time the Portfolio calculates its net asset value due to, among other reasons, infrequent trading or illiquidity. There is a possibility that arbitrage market timing may dilute the value of the Portfolio’s shares if redeeming shareholders receive proceeds (and purchasing shareholders receive shares) based upon a net asset value that does not reflect appropriate fair value prices.

The Board of Directors of the Fund (the “Board”) has adopted a policy (the “Trading Policy”) and the Advisor and DFA Securities LLC (collectively, “Dimensional”) and Dimensional’s agents have implemented the following procedures, which are designed to discourage and prevent market timing or excessive short-term trading in the Fund: (i) trade activity monitoring and purchase blocking procedures; and (ii) use of fair value pricing.

The Fund, Dimensional and their agents monitor trades and flows of money in and out of the Portfolio from time to time in an effort to detect excessive short-term trading activities, and for consistent enforcement of the Trading Policy. The Fund reserves the right to take the actions necessary to stop excessive or disruptive trading activities, including refusing or canceling purchase or exchange orders for any reason, without prior notice, particularly purchase or exchange orders that the Fund believes are made on behalf of market timers. The Fund, Dimensional and their agents reserve the right to restrict, refuse or cancel any purchase or exchange request made by an investor indefinitely if the Fund or Dimensional believe that any combination of trading activity in the accounts is potentially disruptive to the Portfolio. In making such judgments, the Fund and Dimensional seek to act in a manner that is consistent with the interests of shareholders. For purposes of applying these procedures, Dimensional may consider an investor’s trading history in the Portfolio, and accounts under common ownership, influence or control.

In addition to the Fund’s general ability to restrict potentially disruptive trading activity as described above, the Fund also has adopted purchase blocking procedures. Under the Fund’s purchase blocking procedures, where an investor has engaged in any two purchases and two redemptions (including redemptions that are part of an exchange transaction) in the Portfolio in any rolling 30 calendar day monitoring period (i.e., two “round trips”), the Fund and Dimensional intend to block the investor from making any additional purchases in the Portfolio for 90 calendar days (a “purchase block”). If implemented, a purchase block will begin at some point after the transaction that caused the investor to have engaged in the prohibited two round-trips is detected by the Fund, Dimensional, or their agents. The Fund and Dimensional are permitted to implement a longer purchase block, or permanently bar future purchases by an investor, if they determine that it is appropriate.

Under the Fund’s purchase blocking procedures, the following purchases and redemptions will not trigger a purchase block: (i) purchases and redemptions of shares having a value in each transaction of less than $25,000; (ii) purchases and redemptions by U.S. registered investment companies that operate as fund of funds and non-U.S. investment companies that operate as fund of funds that the Funds or Dimensional, in their sole discretion, have determined are not designed and/or are not serving as vehicles for excessive short-term or other disruptive trading (in each case, the fund of funds shall agree to be subject to monitoring by Dimensional); (iii) purchases and redemptions by a feeder portfolio of a master fund’s shares; (iv) systematic or automated transactions where the shareholder, financial advisor or investment fiduciary does not exercise direct control over the investment decision; (v) retirement plan contributions, loans, loan repayments and distributions (including hardship withdrawals) identified as such in the retirement plan recordkeeper’s system; (vi) purchase transactions involving transfers of assets, rollovers, Roth IRA conversions and IRA recharacterizations; (vii) purchases of shares with Portfolio dividends or capital gain distributions; (viii) transfers and reregistrations of shares within the same Portfolio; and (ix) transactions by 529 Plans. Notwithstanding the Fund’s purchase blocking procedures, all transactions in Portfolio shares are subject to the right of the Fund and Dimensional to restrict potentially disruptive trading activity (including purchases and redemptions described above that will not be subject to the purchase blocking procedures).

The Fund, Dimensional or their designees will have the ability, pursuant to Rule 22c-2 under the 1940 Act, to request information from financial intermediaries, such as 401(k) plan administrators, trust companies and broker dealers (together, “Intermediaries”), concerning trades placed in omnibus and other multi-investor accounts (together, “Omnibus Accounts”), in order to attempt to monitor trades that are placed by the underlying shareholders of these Omnibus Accounts. The Fund, Dimensional and their designees will use the information obtained from the Intermediaries to monitor trading in the Fund and to attempt to identify shareholders in Omnibus Accounts engaged in trading that is inconsistent with the Trading Policy or otherwise not in the best interests of the Fund. The Fund, Dimensional or their designees, when they detect trading patterns in shares of the Fund that may constitute short-term or excessive trading, will provide written instructions to the Intermediary to restrict or prohibit further purchases or exchanges of shares of the Portfolio by a shareholder that has been identified as having engaged in excessive or short-term transactions in the Portfolio’s shares (directly or indirectly through the Intermediary’s account) that violate the Trading Policy.

The ability of the Fund and Dimensional to impose these limitations, including the purchase blocking procedures, on investors investing through Intermediaries is dependent on the receipt of information necessary to identify transactions by the underlying investors and the Intermediary’s cooperation in implementing the Trading Policy. Investors seeking to engage in excessive short-term trading practices may deploy a variety of strategies to avoid detection, and despite the efforts of the Fund and Dimensional to prevent excessive short-term trading, there is no assurance that the Fund, Dimensional or their agents will be able to identify those shareholders or curtail their trading practices. The ability of the Fund, Dimensional and their agents to detect and limit excessive short-term trading also may be restricted by operational systems and technological limitations.

Transactions in certain rebalancing programs and asset allocation programs, or fund-of-funds products, may be exempt from the Trading Policy subject to approval by the CCO. In addition, the purchase blocking procedures will not apply to a redemption transaction in which the Portfolio distributes portfolio securities to a shareholder in-kind, where the redemption will not disrupt the efficient portfolio management of the Portfolio and the redemption is consistent with the interests of the remaining shareholders of the Portfolio.

The purchase blocking procedures of the Trading Policy do not apply to shareholders whose shares are held on the books of certain Intermediaries that have not expressly adopted procedures to implement this Policy. The Fund and Dimensional may work with Intermediaries to implement purchase blocking procedures or other procedures that the Fund and Dimensional determine are reasonably designed to achieve the objective of this Trading Policy. At the time the Intermediaries adopt these procedures, shareholders whose accounts are on the books of such Intermediaries will be subject to the Trading Policy’s purchase blocking procedures or another frequent trading policy that achieves the objective of the purchase blocking procedures. Investors that invest in the Portfolio through an Intermediary should contact the Intermediary for information concerning the policies and procedures that apply to the investor.

As of the date of this Prospectus, the ability of the Fund and Dimensional to apply the purchase blocking procedures on purchases by all investors and the ability of the Fund and Dimensional to monitor trades through

Omnibus Accounts maintained by Intermediaries may be restricted due to systems limitations of both the Fund’s service providers and the Intermediaries. The Fund expects that the application of the Trading Policy as described above, including the purchase blocking procedures (subject to the limitations described above), will be able to be implemented by Intermediaries in compliance with Rule 22c-2 under the 1940 Act.

In addition to monitoring trade activity, the Board has approved fair value pricing procedures that govern the pricing of the securities of the Portfolio. These procedures are designed to help ensure that the prices at which Portfolio shares are purchased and redeemed are fair, and do not result in dilution of shareholder interests or other harm to shareholders. See the discussion under “VALUATION OF SHARES—Net Asset Value” for additional details regarding fair value pricing of the Portfolio’s securities.

Although the procedures are designed to discourage excessive short-term trading, none of the procedures individually nor all of the procedures taken together can completely eliminate the possibility that excessive short-term trading activity in the Portfolio may occur. The Portfolio does not knowingly accommodate excessive or disruptive trading activities, including market timing.

The net asset value per share of the Portfolio is generally calculated on days that the NYSE is open for trading. The net asset value per share of the Portfolio is calculated after the close of the NYSE (normally, 4:00 p.m. ET) by dividing the total value of the Portfolio’s investments and other assets, less any liabilities, by the total outstanding shares of the stock of the Portfolio. The Portfolio generally accepts purchase and redemption orders on days that the NYSE is open for trading. Note: The time at which transactions and shares are priced may be changed in case of an emergency or if the NYSE closes at a time other than 4:00 p.m. ET.

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

Securities held by the Portfolio (including over-the-counter securities) are valued at the last quoted sale price of the day. Securities held by the Portfolio that are listed on Nasdaq are valued at the Nasdaq Official Closing Price (“NOCP”). If there is no last reported sale price or NOCP of the day, the Portfolio values the securities at the mean between the most recent quoted bid and asked prices. Price information on listed securities is taken from the exchange where the security is primarily traded. Generally, securities issued by open-end investment companies are valued using their respective net asset values or public offering prices, as appropriate, for purchase orders placed at the close of the NYSE. Generally, options will be valued using the same pricing methods discussed above.

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

As of the date of this Prospectus, the Portfolio will also fair value price in the circumstances described below. Generally, trading in foreign securities markets is completed each day at various times prior to the close of the NYSE. For example, trading in the Japanese securities markets is completed each day at the close of the Tokyo Stock Exchange (normally, 2:00 a.m. ET), which is fourteen hours prior to the close of the NYSE (normally, 4:00 p.m. ET) and the time that the net asset value of the Portfolio is computed. Due to the time differences between the closings of the relevant foreign securities exchanges and the time the Portfolio prices its shares at the close of the NYSE, the Portfolio will fair value its foreign investments when it is determined that the market quotations for the foreign investments are either unreliable or not readily available. The fair value prices will attempt to

reflect the impact of the U.S. financial markets’ perceptions and trading activities on the Portfolio’s foreign investments since the last closing prices of the foreign investments were calculated on their primary foreign securities markets or exchanges. For these purposes, the Advisor has determined that movements in relevant indices or other appropriate market indicators, after the close of the Tokyo Stock Exchange or the London Stock Exchange, demonstrate that market quotations may be unreliable, and may trigger fair value pricing. Consequently, fair valuation of portfolio securities may occur on a daily basis. The fair value pricing by the Portfolio utilizes data furnished by an independent pricing service (and that data draws upon, among other information, the market values of foreign investments). When the Portfolio uses fair value pricing, the values assigned to the Portfolio’s foreign investments may not be the quoted or published prices of the investments on their primary markets or exchanges. The Advisor monitors the operation of the method used to fair value price the International Portfolio’s foreign investments.

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

The net asset value per share of the Portfolio is expressed in U.S. dollars by translating the net assets of the Portfolio using the mean of the most recent bid and asked prices for the dollar as quoted by generally recognized reliable sources. Because the Portfolio owns securities that are primarily traded in foreign markets which may trade on days when the Portfolio does not price its shares, the net asset value of the Portfolio may change on days when shareholders will not be able to purchase or redeem shares.

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

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

Provided that the transfer agent has received the investor’s purchase order in good order as described in “Purchase of Shares,” shares of the Portfolio will be priced at the public offering price, which is the net asset value of the shares next determined after receipt of such order. The transfer agent or the Fund may, from time to time, appoint sub-transfer agents or various financial intermediaries (“Intermediaries”) for the receipt of purchase orders, redemption orders and funds from certain investors. Intermediaries, in turn, are authorized to designate other financial intermediaries (“Sub-designees”) to receive purchase and redemption orders for the Portfolio’s shares from investors. With respect to such investors, the shares of the Portfolio will be priced at the public offering price calculated after receipt of the purchase order by the Intermediary or Sub-designee, as applicable, that is authorized to receive purchase orders. If the investor buys shares through an Intermediary or a Sub-designee, the purchase price will be the public offering price next calculated after the Intermediary or Sub-designee, as applicable, receives the order, rather than on the day the custodian receives the investor’s payment (provided that the Intermediary or Sub-designee, as applicable, has received the investor’s purchase order in good order, and the investor has complied with the Intermediary’s or Sub-designee’s payment procedures). No reimbursement fee or sales charge is imposed on purchases. If an order to purchase shares must be canceled due to non-payment, the purchaser will be responsible for any loss incurred by the Portfolio arising out of such cancellation. The Fund reserves the right to redeem shares owned by any purchaser whose order is

canceled to recover any resulting loss to the Portfolio and may prohibit or restrict the manner in which such purchaser may place further orders.

Investors may exchange shares of the Portfolio for those of another portfolio of the Fund by first contacting the Portfolio’s transfer agent at (888) 576-1167 to notify the transfer agent of the proposed exchange and then sending a letter of instruction to the transfer agent by an approved method. Shareholders that invest in the Portfolio through a financial intermediary should contact their financial intermediary for information regarding exchanges.

Exchanges are accepted into those portfolios that are eligible for the exchange privilege, subject to the purchase requirement set forth in the applicable portfolio’s prospectus. Investors may contact the transfer agent at the above-listed phone number for more information on such exchanges, for a list of those portfolios that accept exchanges, and to request a copy of the prospectuses of other portfolios of the Fund or Dimensional Investment Group Inc. that may be offered in an exchange. There is no fee imposed on an exchange. However, the Fund reserves the right to impose an administrative fee in order to cover the costs incurred in processing an exchange. Any such fee will be disclosed in the Prospectus. An exchange is treated as a redemption and a purchase. Therefore, an investor could realize a taxable gain or a loss on the transaction. The Fund reserves the right to revise or terminate the exchange privilege, or limit the amount of or reject any exchange, as deemed necessary, at any time.

The exchange privilege is not intended to afford shareholders a way to speculate on short-term movements in the markets. Accordingly, in order to prevent excessive use of the exchange privilege that may potentially disrupt the management of the portfolios or otherwise adversely affect the Fund, any proposed exchange will be subject to the approval of the Advisor. Such approval will depend on: (i) the size of the proposed exchange; (ii) the prior number of exchanges by that shareholder; (iii) the nature of the underlying securities and the cash position of the portfolios involved in the proposed exchange; (iv) the transaction costs involved in processing the exchange; and (v) the total number of redemptions by exchange already made out of a portfolio. Excessive use of the exchange privilege is defined as any pattern of exchanges among portfolios by an investor that evidences market timing.

The redemption and purchase prices of shares redeemed and purchased by exchange, respectively, are the net asset values next determined after the transfer agent has received a letter of instruction in good order. “Good order” means a completed letter of instruction specifying the dollar amount to be exchanged, signed by all registered owners of the shares (or representatives thereof); and if the Fund does not have on file the authorized signatures for the account, proof of authority. Exchanges will be accepted only if the shares of the portfolio being acquired are registered in the investor’s state of residence.

Investors who desire to redeem shares of the Portfolio must first contact the Portfolio’s transfer agent at (888) 576-1167. Shareholders who invest in the Portfolio through a financial intermediary should contact their financial intermediary regarding redemption procedures. The Portfolio will redeem shares at the net asset value of such shares next determined, after receipt of a written request for redemption in good order, by the transfer agent (or by an Intermediary or a Sub-designee, if applicable). “Good order” means that the request to redeem shares must include all necessary documentation, to be received in writing by the transfer agent no later than the close of regular trading on the NYSE (normally, 4:00 p.m. ET) (“Market Close”), including but not limited to, a letter of instruction specifying the number of shares or dollar amount to be redeemed, signed by all registered owners (or representatives thereof) of the shares and, if the Fund does not have on file the authorized signatures for the account, proof of authority. It is the investor or financial intermediary’s responsibility to ensure notification is received in good order by the transfer agent prior to the Market Close on the redemption date.

Under certain conditions, the Portfolio may accept and process redemption orders after the close of the NYSE on days that the NYSE unexpectedly closes early and may accept orders on a business day that the NYSE is unexpectedly closed. All orders will be processed at the next determined net asset value per share.

Shareholders redeeming shares who do not already have an agreement in place with the Fund and have authorized redemption payment by wire in writing, may request that redemption proceeds be paid in federal funds wired to the bank they have designated in writing. The Fund reserves the right to send redemption proceeds by check in its discretion; a shareholder may request overnight delivery of such check at the shareholder’s own expense. If the proceeds are to be wired to a bank account that differs from the standing instructions on file, or paid by check to an address other than the address of record, the transfer agent may request a Medallion Signature Guarantee. If the proceeds are wired to the shareholder’s account at a bank that is not a member of the Federal Reserve System, there could be a delay in crediting the funds to the shareholder’s bank account. The Fund reserves the right at any time to suspend or terminate the redemption by wire procedure after prior notification to shareholders. No fee is charged for redemptions. The redemption of all shares in an account will result in the account being closed. A new Account Registration Form will be required for future investments. See “PURCHASE OF SHARES.” In the interests of economy and convenience, certificates for shares are not issued.

For redemption proceeds that are paid directly to a shareholder by the Portfolio, the Portfolio typically expects to send (via check, wire or automated clearing house) redemption payments within 1 business day after receipt of a written request for redemption in good order by the transfer agent. For payments that are made to an intermediary for transmittal to a shareholder, the Portfolio expects to pay redemption proceeds to the intermediary within 1 to 2 business days following the Portfolio’s receipt of the redemption order from the intermediary. Under certain circumstances and when deemed in the best interest of the Portfolio, redemption proceeds may take up to seven calendar days to be sent after receipt of the redemption request. In addition, with respect to investors redeeming shares that were purchased by check, payment will not be made until the Fund can verify that the payments for the purchase have been, or will be, collected, which may take more than seven calendar days. Investors may avoid this delay by submitting a certified check along with the purchase order.

Redemption proceeds will typically be paid by Federal Reserve wire payment. The Portfolio typically expects to satisfy redemption requests from available cash and cash equivalents or the sale of portfolio assets. In certain circumstances, such as stressed market conditions, the Portfolio may use other methods to meet redemptions, including the use of a line of credit or participating in an interfund lending program in reliance on exemptive relief from the SEC. In addition, as described below, the Portfolio reserves the right to meet redemption requests through an in-kind redemption, typically in response to a particularly large redemption, at the request of a client or in stressed market conditions. Also, see “Redemption and Transfer of Shares” in the SAI for information regarding redemption requests that exceed $250,000 or 1% of the value of the Portfolio’s assets, whichever is less.

The Fund reserves the right to redeem an account if the value of the shares in the Portfolio is $500 or less. Before the Fund involuntarily redeems shares from such an account and sends the proceeds to the stockholder, the Fund will give written notice of the redemption to the stockholder at least sixty days before the redemption date. The stockholder will then have sixty days from the date of the notice to make an additional investment in order to bring the value of the shares in the account for the Portfolio to more than $500 and avoid such involuntary redemption. The redemption price to be paid to a stockholder for shares redeemed by the Fund under this right will be the aggregate net asset value of the shares in the account at the close of business on the redemption date.

The Portfolio may make a redemption payment, in whole or in part, by a distribution of portfolio securities that the Portfolio owns in lieu of cash, when in the best interests of the Portfolio. The Portfolio is also authorized to make redemption payments solely by a distribution of portfolio securities (or a combination of securities and cash) when it is determined by the Advisor to be consistent with the tax management strategies described in this

Prospectus. Such distributions may be pro rata or another method that is determined to be fair to both the redeeming shareholder and the remaining shareholders in accordance with policies and procedures adopted by the Fund. Investors may incur brokerage charges and other transaction costs when selling securities that were received in payment of redemptions. The Portfolio reserves the right to redeem its shares in the currencies in which its investments are denominated. Investors may incur charges in converting such securities to dollars and the value of the securities may be affected by currency exchange fluctuations.

The Portfolio generally will disclose up to its 25 largest portfolio holdings (other than cash and cash equivalents) and the percentages that each of these largest portfolio holdings represent of the total assets of the Portfolio, as of the most recent month-end, online at the Advisor’s public Web site, http://us.dimensional.com, within 20 days after the end of each month. The Portfolio also generally will disclose its complete portfolio holdings (other than cash and cash equivalents), as of month-end, online at the Advisor’s public Web site, 30 days following the month-end or more frequently and at different periods when authorized in accordance with the Portfolio’s policies and procedures. The Portfolio may, but is not required to, disclose a list of portfolio securities that generally would be included as proceeds in a redemption in-kind, as frequently as on a daily basis, online at the Advisor’s public Web site. Please consult the SAI for a description of the other policies and procedures that govern disclosure of the portfolio holdings by the Portfolio.

To eliminate duplicate mailings and reduce expenses, the Portfolio may deliver a single copy of certain shareholder documents, such as this Prospectus and annual and semi-annual reports, to related shareholders at the same address, even if accounts are registered in different names. This practice is known as “householding.” The Portfolio will not household personal information documents, such as account statements. If you do not want the mailings of these documents to be combined with other members of your household, please call the transfer agent at (888) 576-1167. We will begin sending individual copies of the shareholder documents to you within 30 days of receiving your request.
