Investment Objective

The investment objective of the Japanese Small Company Portfolio (the "Portfolio") is to achieve long-term capital appreciation. The Japanese Small Company Portfolio is a Feeder Portfolio and pursues its objective by investing substantially all of its assets in its corresponding Master Fund, The Japanese Small Company Series (the "Japanese Small Company Series" or the "Series") of The DFA Investment Trust Company (the "Trust"), which has the same investment objective and policies as the Portfolio.

Fees and Expenses of the Portfolio

This table describes the fees and expenses you may pay if you buy, hold or sell shares of the Japanese Small Company Portfolio. **You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.**

**Shareholder Fees (fees paid directly from your investment): None**

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

---

| | |
|:---|:---|
| Management Fee | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **0.45%** |
| Other Expenses | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **0.05%** |
| Total Annual Fund Operating Expenses | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **0.50%** |
| Fee Waiver and/or Expense Reimbursement | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **0.10%** |
| Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **0.40%** |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \* &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The "Management Fee" and "Total Annual Fund Operating Expenses" have been adjusted to reflect the decrease in the management fee payable by the Feeder Portfolio from 0.40% to 0.35% effective as of February 28, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \*\* &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The "Management Fee" includes an investment management fee payable by the Feeder Portfolio and an investment management fee payable by the Master Fund. For any period when the Feeder Portfolio is invested in other funds managed by Dimensional Fund Advisors LP (the "Advisor") (collectively, "Underlying Funds"), the Advisor has contractually agreed to permanently waive the Feeder Portfolio's direct investment management fee to the extent necessary to offset the proportionate share of any Underlying Fund's investment management fee paid by the Feeder Portfolio through its investment in such Underlying Fund. The amounts set forth under "Other Expenses" and "Total Annual Fund Operating Expenses" reflect the direct expenses of the Feeder Portfolio and the indirect expenses of the Feeder Portfolio's portion of the expenses of the Master Fund.

**EXAMPLE**

This Example is meant to help you compare the cost of investing in the Japanese Small Company Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **1 Year** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **3 Years** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **5 Years** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **10 Years** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **$41** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **$128** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **$224** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **$505** |

---

The Example reflects the aggregate annual operating expenses of the Japanese Small Company Portfolio and the Portfolio's portion of the expenses of the Japanese Small Company Series.

**PORTFOLIO TURNOVER**

The Japanese Small Company Series 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Japanese Small Company Portfolio's performance. During the most recent fiscal year, the Series' portfolio turnover rate was 11% of the average value of its investment portfolio.

Principal Investment Strategies

The Japanese Small Company Portfolio is a feeder portfolio that invests substantially all of its assets in the Japanese Small Company Series. To achieve the Portfolio's and the Series' investment objectives, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Series' design emphasizes long-term drivers of expected returns identified by the Advisor's research, while balancing risk through broad diversification across companies and sectors. The Advisor's portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The Japanese Small Company Series, using a market capitalization weighted approach, is designed to purchase a broad and diverse group of readily marketable securities of small companies associated with Japan. A company's market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Series than

Japanese Small Company Portfolio Summary Prospectus 3<br>

------

companies with relatively lower market capitalizations. The Series may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small company segment of the Japanese market. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time.

As a non-fundamental policy, under normal circumstances, the Japanese Small Company Series will invest at least 80% of its net assets in securities of Japanese small companies. The Advisor first ranks eligible companies by market capitalization. The Advisor then determines the universe of eligible securities by defining the maximum market capitalization of a small company in Japan. Based on market capitalization data as of December 31, 2022, the Advisor would consider Japanese small companies to be those companies with a market capitalization below $2,035 million. This threshold will change due to market conditions.

The Advisor may also increase or reduce the Japanese Small Company Series' exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company's price momentum and investment characteristics. In assessing a company's investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company's investment characteristics are subject to change from time to time. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The Japanese Small Company Series may gain exposure to companies associated with Japan by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer's domicile country. The Series and the Japanese Small Company Portfolio each may purchase or sell futures contracts and options on futures contracts for Japanese equity securities and indices or other equity market securities and indices, including those of the United States, to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Series or Portfolio. Because many of the Series' and the Portfolio's investments may be denominated in foreign currencies, the Series and the Portfolio may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer cash balances from one currency to another currency.

The Japanese Small Company Series may lend its portfolio securities to generate additional income.

Principal Risks

Because the value of your investment in the Japanese Small Company 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.

***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.

***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 Series does not hedge foreign currency risk.

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

***Japan Market Risk:*** Because the Series concentrates investments in Japan, the Portfolio's performance is expected to be closely tied to the social, political and economic conditions within Japan and to be more volatile than the performance of funds with more geographically diverse investments.

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

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

Japanese Small Company Portfolio Summary Prospectus 5<br>

------

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

***Derivatives Risk:*** Derivatives are instruments, such as futures, and options thereon, and foreign currency forward contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When the Series and the Portfolio use derivatives, the Portfolio will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Portfolio could lose more than the principal amount invested.

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

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

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