The Emerging Markets Sustainability Core 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 13% of the average value of its investment portfolio.

Strategy Narrative [Text Block]

To achieve the Emerging Markets Sustainability Core Portfolio’s investment objective, Dimensional Fund Advisors LP (the “Advisor”) implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes

long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors. The Advisor’s portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The Emerging Markets Sustainability Core Portfolio is designed to purchase a broad and diverse group of securities associated with emerging markets. The Portfolio invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the Emerging Markets Universe, while adjusting the composition of the Portfolio based on sustainability impact considerations. For purposes of this Portfolio, the Advisor defines the Emerging Markets Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the Emerging Markets Universe it represents) of companies in emerging markets, which may include frontier markets (emerging market countries in an earlier stage of development), authorized for investment by the Advisor’s Investment Committee (“Approved Markets”). The Portfolio’s increased exposure to smaller capitalization, lower relative price, and higher profitability companies may be achieved by decreasing the allocation of the Portfolio’s assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the Emerging Markets Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time.

The Advisor may also increase or reduce the Emerging Markets Sustainability Core Portfolio’s 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.

As a non‑fundamental policy, under normal circumstances, the Emerging Markets Sustainability Core Portfolio will invest at least 80% of its net assets in emerging markets equity investments that are defined in the Prospectus as Approved Markets securities. The Portfolio may gain exposure to companies associated with Approved Markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer’s domicile country.

The Emerging Markets Sustainability Core Portfolio may purchase or sell futures contracts and options on futures contracts for Approved Markets 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 Portfolio. The above-referenced investments are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

The Emerging Markets Sustainability Core Portfolio may lend its portfolio securities to generate additional income.

The Advisor intends to take into account the impact that companies may have on the environment and other sustainability considerations when making investment decisions for the Emerging Markets Sustainability Core Portfolio. Relative to a portfolio without these considerations, the Portfolio will exclude or underweight securities of companies that, according to the Portfolio’s sustainability impact considerations, may be less sustainable as compared either to other companies in the Portfolio’s investment universe or other companies with similar business lines. Similarly, relative to a portfolio without sustainability impact considerations, the Portfolio will overweight securities of companies that, according to the Portfolio’s sustainability impact considerations, may be more sustainable as compared either to other companies in the Portfolio’s investment universe or other companies with similar business lines. In considering sustainability impact and other factors that the Advisor

believes may be important to investors, the Advisor may consider carbon and other greenhouse emissions, or potential emissions, land use, cluster munitions manufacturing, landmine manufacturing, civilian firearms manufacturing, biodiversity, involvement in toxic spills or releases, operational waste, water use, tobacco, palm oil, coal, involvement with private prisons and/or immigrant detention facilities, child labor, and factory farming activities, among other factors. In particular, the Portfolio will exclude companies the Advisor considers to have high carbon or greenhouse gas emissions or reserves that may produce those emissions. The Advisor may engage third party service providers to provide research and/or ratings information relating to the Portfolio’s sustainability impact considerations with respect to securities in the portfolio, where information is available from such providers.

The Portfolio may periodically modify, add, or remove certain sustainability impact considerations. (See “Additional Information on Investment Objectives and Policies—Applying the Sustainability Portfolios’ Sustainability Impact Considerations” in this Prospectus.)

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Because the value of your investment in the Emerging Markets Sustainability Core 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.

Sustainability Impact Consideration Investment Risk: The Portfolio’s sustainability impact considerations may limit the number of investment opportunities available to the Portfolio, and as a result, at times, the Portfolio may underperform funds that are not subject to such sustainability impact considerations. For example, the Portfolio may decline to purchase, or underweight its investment in, certain securities due to sustainability impact considerations when other investment considerations would suggest that a more significant investment in such securities would be advantageous. The Portfolio may also overweight its investment in certain securities due to sustainability impact considerations when other investment considerations would suggest that a lesser investment in such securities would be advantageous. In addition, the Portfolio may sell or retain certain securities due to sustainability impact considerations when it is otherwise disadvantageous to do so. The sustainability impact considerations may also cause the Portfolio’s industry allocations to deviate from that of funds without these considerations and of conventional benchmarks. The Advisor may also not be able to assess the sustainability impact of each company eligible for purchase by the Portfolio. For example, the Advisor may not be able to determine an overall sustainability impact score for each company based on the sustainability considerations because the third party service providers may not have data on the entire universe of companies considered by the Advisor for the Portfolio, or may not have information with respect to each factor considered as a sustainability impact consideration. Furthermore, “sustainability” is not uniformly defined, and there are significant differences in interpretations of what it means for a company to meet sustainability criteria. The Advisor’s assessment of a company’s sustainability impact may differ from assessments made by other funds, managers, or investors. As a result, there is no guarantee that the Portfolio’s investments will reflect the sustainability considerations of any particular investor.

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 Portfolio 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.

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.

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

China Investments Risk: There are special risks associated with investments in China and Taiwan, which are considered emerging market countries by the Portfolio. 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.

A reduction in spending on Chinese products and services or the institution of additional tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States may also have an adverse impact on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to the Portfolio. The Portfolio may also invest in special structures that utilize contractual arrangements to provide exposure to certain Chinese companies, known as variable interest entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments. The Chinese government’s acceptance of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure or whether Chinese courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each of which would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

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.

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.

Derivatives Risk: Derivatives are instruments, such as futures, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non‑hedging purposes may be considered to carry more risk than other types of investments. When 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.

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.

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, among 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.
