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

**EXAMPLE**

This Example is meant to help you compare the cost of investing in the Enhanced U.S. Large 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. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual

**PORTFOLIO TURNOVER**

The Enhanced U.S. Large Company Portfolio 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 Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 118% of the average value of its investment portfolio.

Principal Investment Strategies

The Enhanced U.S. Large Company Portfolio seeks to outperform the S&P 500® Index primarily through investment in S&P 500® Index futures and short-term fixed income obligations. The Portfolio may invest in all of the stocks represented in the S&P 500® Index, options on stock indices, stock index futures, options on stock index futures, swap agreements on stock indices and shares of investment companies, such as exchange-traded funds (ETFs) that invest in stocks represented in the S&P 500® Index or other similar stock indices. The Portfolio invests in fixed income obligations, which may include securities of foreign issuers. The Portfolio may, from time to time, also invest in options on stock indices, stock index futures, options on stock index futures and swap agreements based on indices other than, but similar to, the S&P 500® Index (such instruments whether or not based on the S&P 500® Index are hereinafter collectively referred to as "Index Derivatives"). The S&P 500® Index comprises a broad and diverse group of stocks. Generally, these are the U.S. stocks with the largest market capitalizations and, as a group, they generally represent approximately 80% of the total market capitalization of all publicly traded U.S. stocks. The Advisor considers stocks that comprise the S&P 500® Index to be those of large companies. Under normal circumstances, the Portfolio will invest at least 80% of its net assets in short-term fixed income obligations that are overlaid by futures, swaps and other derivatives of the S&P 500® Index to create exposure to the performance of large U.S. companies or in securities of large U.S. companies directly. Alternatively, the Portfolio may invest at least 80% of its net assets directly in securities of large companies.

The Enhanced U.S. Large Company Portfolio may invest all of its assets in Index Derivatives. Certain of these Index Derivatives may be considered speculative and may subject the Portfolio to additional risks. Assets of the Portfolio not invested in the S&P 500® Index or Index Derivatives may be invested in short-term fixed

income obligations including: U.S. government obligations, U.S. government agency obligations, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, foreign government and agency obligations, supranational organization obligations, foreign issuer obligations and eurodollar obligations. The Portfolio's investment in fixed income obligations will be considered investment grade at the time of purchase. The fixed income obligations purchased by the Portfolio will typically mature within three years or less from the date of settlement and the average dollar-weighted maturity of the fixed income obligations will be two years or less.

The Enhanced U.S. Large Company Portfolio may use foreign currency forward contracts to hedge foreign currency risks or to transfer balances from one currency to another. The Portfolio uses index swap agreements and/or stock index futures to hedge against changes in securities prices. The Portfolio may purchase or sell futures contracts and options on futures contracts to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio. Additionally, the Portfolio uses index swap agreements and stock index futures to attempt to achieve its investment objectives.

The Enhanced U.S. Large Company Portfolio may lend its portfolio securities to generate additional income.

About the S&P 500® Index: The Standard & Poor's 500 Composite Stock Price Index® is market capitalization weighted (adjusted for free float). Its performance is usually cyclical because it reflects periods when stock prices generally rise or fall. For information concerning S&P Global Ratings, a division of The McGraw Hill Companies ("S&P"), and disclaimers of S&P with respect to the Enhanced U.S. Large Company Portfolio, see **"Standard & Poor's—Information and Disclaimers."**

Principal Risks

Because the value of your investment in the Enhanced U.S. Large 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,

4 Dimensional Fund Advisors<br>

------

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 Portfolio hedges foreign currency risk.

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

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

------

***Securities Lending Risk:*** Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, the 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.

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

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

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

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

***Liquidity Risk:*** Liquidity risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that the Portfolio holds illiquid investments, the Portfolio's performance may be reduced due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by the Portfolio due to low trading volume, adverse

investor perceptions and/or other market developments. Liquidity risk includes the risk that the Portfolio will experience significant net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of shares of the Portfolio are concentrated in one or a few investors.

***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.
