Strategy Narrative [Text Block] The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in dividend-paying U.S. large- and mid-cap equity securities.These dividend-paying U.S. large- and mid-cap equity securities are incorporated in, or have their primary listing in, the United States. Dividend-paying U.S. equity securities in which the fund may invest include common and preferred stocks, convertible securities, rights, warrants, and real estate investment trusts (“REITs”) listed on any U.S. exchange. The fund considers the large- and mid-cap U.S. equity universe to be those U.S. equity securities in the top 85% of the free-float adjusted U.S. market capitalization. The selection and weighting of the securities in the fund will be based on a proprietary systematic approach. According to this proprietary systematic approach, the initial investment universe will first be screened for securities that have high and persistent dividends or dividends that are expected to grow over time. Following this screening, the portfolio is then optimized. During the optimization process, security factors and portfolio factors are evaluated to optimize weights. Elements of this proprietary systematic approach are subject to change over time. While the fund manages risk by investing in securities across a broad range of industries and market sectors, the fund may at times focus its investments in a particular sector or sectors of the U.S. equity markets.

Strategy Narrative [Text Block] The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities that compose the fund’s Index.The Index is developed and maintained by Dimensional Fund Advisors LP and is designed to comprise a subset of securities in the U.S. Universe issued by companies whose market capitalizations are larger than that of the 801st largest U.S. company at the time of reconstitution.The selection and weighting of securities in the Index involves a rules-based process that may sometimes be referred to as multifactor investing, factor-based investing, strategic beta, or smart beta. Securities are classified according to their market capitalization, relative price, and profitability. Weights for individual securities are then determined by adjusting their free-float adjusted market capitalization weight within the universe of eligible securities so that securities with smaller market capitalizations, lower relative price and higher profitability generally receive an increased weight relative to their unadjusted weight, and vice versa. This process can be summarized as follows: Adjustments for market capitalization: Securities within the eligible universe are assigned into one of three groups based on size, with the intent of increasing the weights of securities with smaller market capitalizations within the eligible universe and decreasing weights of securities with larger market capitalizations within the eligible universe. Securities in the smallest market capitalization group will have their free-float market capitalization increased by an adjustment factor. Securities in the middle group will have their free-float market capitalization increased by a lesser adjustment factor. Securities in the group with the largest market capitalization will receive the lowest adjustment factor of the three groups. Adjustments for relative price and profitability: Adjustments for relative price and profitability are implemented on a sector-by-sector basis. Within each sector, securities (other than real estate investment trusts (REITs)) are assigned to a relative price group and to a profitability group. REITs are generally assigned to separate relative price and profitability groups. Relative price adjustment factors are assigned with the intent of increasing the weights of securities with lower relative prices and decreasing the weights of securities with higher relative prices. Similarly, profitability adjustment factors are assigned with the intent of increasing the weights of securities with higher profitability and decreasing the weights of securities with lower profitability. Relative price and profitability adjustment factors for REITs will generally act to reduce their weight relative to their unadjusted weight in the U.S. Universe. Securities are then weighted after taking into account their free-float, size, relative price and profitability adjustments, subject to a cap of 4% on a single company at the time of reconstitution. The Index is reconstituted and rebalanced on a semiannual basis. The U.S. Universe is defined as a free float-adjusted market-capitalization-weighted portfolio of U.S. operating companies listed on the New York Stock Exchange (NYSE), NYSE American LLC, NASDAQ Global Market, or such other securities exchanges deemed appropriate in accordance with the rules-based methodology that is maintained by Dimensional Fund Advisors LP. This means that the market-capitalization of a particular company within the eligible universe of stocks is adjusted to exclude the share capital of a company that is not considered freely available for trading in the public equity markets. The fund, using an indexing investment approach, attempts to approximate the investment performance of the Index by investing in a portfolio of securities that generally replicates the Index. The fund may concentrate its investments in a particular industry or group of industries to the extent that the Index concentrates in an industry or group of industries.

Derivatives transactions include credit default swaps, foreign currency forward contracts, futures contracts, and options. The fund may engage in derivatives transactions to reduce risk and/or obtain efficient market exposure. The fund may trade securities actively.

Under normal market conditions, the fund will limit its investments in U.S. dollar-denominated foreign securities (excluding Canadian securities) to 30% of its total assets.

The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of equity and equity-related securities issued by non-U.S. large and mid-capitalization value companies that meet the fund’s value criteria.The fund may invest in all types of equity and equity-related securities, including, without limitation, exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, participatory notes, limited partnership interests, shares of other investment companies (including exchange-traded funds (ETFs)), real estate investment trusts (REITs), and equity participations. Equity participations are loans that give the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock, or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula.The manager defines value companies as those companies that are included within the MSCI EAFE Value Index or that exhibit attractive value characteristics based on financial metrics, such as price-to-book ratio, price-to-earnings ratio, price-to-sales ratio, enterprise-value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) ratio or price-to-free-cash-flow ratio relative to a broader core, or non-style-specific, investment universe as represented by the MSCI EAFE Index. The fund defines non-U.S. companies as companies: (i) that are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets, or that derive a majority of their revenue or profits, from businesses, investments, or sales outside of the United States. The fund’s non-U.S. investments, which may be denominated in U.S. or foreign currencies, primarily focus on developed markets, but may include emerging- and frontier-market investments. The fund defines large and mid-capitalization as those companies with a market capitalization over $250 million.The fund generally invests in the equity securities of issuers the manager believes are undervalued. The manager applies a bottom-up stock selection process using a combination of fundamental and quantitative analysis of issuer-specific factors such as price-to-book value, price-to-sales and earnings ratios, dividend yields, strength of management, and cash flow. The fund may invest in derivatives. Derivatives may be used to reduce risk, obtain efficient market exposure, and/or enhance investment returns, and may include put and call options, futures, forward contracts, and swaps. The fund may invest up to 15% of its net assets in illiquid securities and may participate as a purchaser in Initial Public Offerings (IPOs). The fund may also seek to increase its income by lending portfolio securities. Due to the nature of certain of the fund’s investments, the fund may, under certain circumstances, effect a portion or all of creations and redemptions for cash, rather than in-kind securities. The fund is non-diversified, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.

Strategy Narrative [Text Block] The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its net assets, plus amounts borrowed for investment purposes, in municipal bonds of any maturity.The fund primarily invests in bonds that are investment grade when purchased, but the fund may also invest up to 20% of its net assets in non-investment grade bonds rated BB or lower by S&P Global Ratings (S&P), Fitch Ratings (Fitch), or Moody’s Investors Service, Inc. (Moody’s), or comparable rating by any nationally recognized statistical ratings organization (NRSRO) or unrated equivalents (also called junk bonds). The fund may invest in other fixed income securities which include bonds, debt securities and other similar instruments. The fund’s investment policies are based on credit ratings at the time of purchase. The fund may invest in general obligation bonds, however, in general, the manager favors bonds backed by revenue from a specific public project or facility, such as a power plant (revenue bonds), as they tend to offer higher yields than general obligation bonds. The manager also favors bonds that have limitations on early payoff (call protection), which can help minimize the effect of falling interest rates on the fund’s yield. To the extent that the fund invests in bonds that are subject to the alternative minimum tax (AMT), the income paid by the fund may not be entirely tax-free to all investors. Investments in bonds subject to the AMT will be counted toward the fund’s 80% investment policy. The fund may buy bonds of any maturity or duration. The manager may implement short-term trading strategies to take advantage of pricing imbalances within the municipal bond market. There is no guarantee that the manager will be able to implement these strategies effectively and the strategies may have a more significant impact on the fund's performance before it achieves scale. The fund may invest heavily in bonds from any given state or region, and may have substantial investments in obligations of certain states and their agencies, instrumentalities, and/or political subdivisions. The fund may also use tender option bond transactions to seek to enhance potential gains. The fund will look through to the underlying municipal bonds held by a tender option bond trust for purposes of the fund’s 80% policy. The fund may leverage its assets through the use of proceeds received as a result of tender option bond transactions. The fund may contribute up to 15% of its holdings in municipal securities to tender option bond transactions. Due to the nature of certain of the fund’s investments, the fund may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities.

Summary of Selection Criteria for Rule 35d-1 Term in Fund Name [Text Block] The fund primarily invests in bonds that are investment grade when purchased, but the fund may also invest up to 20% of its net assets in non-investment grade bonds rated BB or lower by S&P Global Ratings (S&P), Fitch Ratings (Fitch), or Moody’s Investors Service, Inc. (Moody’s), or comparable rating by any nationally recognized statistical ratings organization (NRSRO) or unrated equivalents (also called junk bonds). The fund may invest in other fixed income securities which include bonds, debt securities and other similar instruments. The fund’s investment policies are based on credit ratings at the time of purchase. The fund may invest in general obligation bonds, however, in general, the manager favors bonds backed by revenue from a specific public project or facility, such as a power plant (revenue bonds), as they tend to offer higher yields than general obligation bonds. The manager also favors bonds that have limitations on early payoff (call protection), which can help minimize the effect of falling interest rates on the fund’s yield.
Rule 35d-1 Eighty Percent Investment Policy [Text Block] Under normal market conditions, the fund invests at least 80% of its net assets, plus amounts borrowed for investment purposes, in municipal bonds of any maturity.

The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its net assets in equity securities.Market capitalizations of these companies will span the capitalization spectrum. Equity securities include exchange-traded common and preferred securities (and exchange-traded futures providing such exposure). The manager seeks to identify companies that demonstrate key growth drivers, sustainable cash flow production, and high returns on capital, sustainable competitive advantages, and strong management. The manager looks for both growth and value opportunities, using the present value of estimated future cash flows to measure intrinsic value. The fund may focus its investments in a particular sector or sectors of the economy.The manager’s fundamental research process produces bottom-up company assessments using key assumptions that drive sales, margins, and asset intensity. The manager seeks to purchase company shares that are selling at a significant discount to intrinsic value. Sell decisions are similarly driven by long-term fundamental analysis. The manager may sell a holding if the holding reaches its target valuation, the manager perceives deterioration in the business’s underlying fundamentals, or a more attractive opportunity is identified. Because the fund is actively managed, it may trade securities actively. The fund may invest up to 20% of its net assets in equity securities of foreign issuers, including American Depositary Receipts. The fund may invest only in common stocks listed on a foreign exchange that trade contemporaneously with the fund's shares. Investments in ETFs may be used to reduce risk and/or obtain efficient investment exposure. The fund is an actively managed semi-transparent ETF that operates pursuant to an exemptive order from the Securities and Exchange Commission (Order) and is not required to publicly disclose its complete portfolio holdings each business day. Instead, the fund publishes each business day on its website a “Tracking Basket,” which is designed to closely track the daily performance of the fund but is not the fund's actual portfolio. The Tracking Basket is composed of: (1) select recently disclosed portfolio holdings and/or select securities from the universe from which the fund's investments are selected (Strategy Components); (2) liquid U.S. exchange-traded ETFs that convey information about the types of instruments (that are not otherwise fully represented by the Strategy Components) in which the fund invests (Representative ETFs); and (3) cash and cash equivalents. For additional information regarding the Tracking Basket, see “Additional information about the fund” section in the prospectus. The fund also publishes each business day on its website the “Tracking Basket Weight Overlap,” which is the percentage weight overlap between the holdings of the prior business day's Tracking Basket compared to the holdings of the fund that formed the basis for the fund's calculation of net asset value per share (NAV) at the end of the prior business day. The Tracking Basket Weight Overlap is designed to provide investors with an understanding of how similar the Tracking Basket is to the fund's actual portfolio in percentage terms.

Strategy Narrative [Text Block] The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its assets (plus any borrowings for investment purposes) in a diversified portfolio of Senior Loans (as defined below).“Senior Loans” are investments in originated first and second lien loans, delayed draw term loans, revolving credit facilities, and club deals and will include, but are not limited to, senior secured floating rate bank loans and investments that provide exposure to senior loans.These types of investments are called “senior loans” because they are generally secured by a borrower’s assets pursuant to a first or second priority or “senior” lien, ranking above unsecured and subordinated bonds. Such loans pay a coupon and repay the bulk of principle at maturity. This means that the asset class has little or no interest rate duration. Senior loans do not include commercial mortgage loans (including subordinated real estate mezzanine financing). The fund may invest in loans either by transacting directly at the initial funding date or acquiring loans in secondary market transactions. The fund’s commitments in connection with a portion of the loans in which it invests may be unfunded. The fund may invest, without limitation, in high yield investments (commonly referred to as junk bonds), that are rated below investment grade by Moody’s Investors Services, Inc. or equivalently rated by Standard & Poor’s Rating Services, Fitch Ratings, Kroll Bond Rating Agency or DBRS Morningstar or, their unrated equivalents as determined to be of comparable credit quality by the fund’s manager.The fund may invest in instruments denominated in foreign currencies. The fund may also invest in U.S. dollar-denominated instruments of foreign issuers. The fund currently expects to invest at least 40% of its assets in non-U.S. securities, representing issuers economically tied to a number of European countries. The percentage of assets invested in non-U.S. securities will vary over time. The fund may also invest in collateralized loan obligations (CLO’s), corporate debt securities, (investment grade and high yield), and cash and cash equivalents. The fund considers CLOs that provide exposure to senior loans as “senior loans” for purposes of its 80% policy. The fund may engage in derivatives transactions for hedging, risk management and/or efficient portfolio management purposes. Derivative instruments in which the fund may invest include credit default swap and total return swap agreements, interest rate swaps, foreign currency forward contracts, futures and options. Derivative instruments may magnify the fund’s gains and losses. The fund does not employ the use of leverage. The fund may trade investments actively.

Strategy Narrative [Text Block] The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index.The fund will pursue its objective through a combination of high-conviction fundamental equity selection and a dynamic options overlay. Under normal circumstances, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of equity securities.Equity securities include common and preferred stocks and their equivalents, including real estate investment trusts (REITs), American Depositary Receipts (ADRs), warrants, rights, and convertible securities, as well as derivatives on those common stock positions or derivatives on broad equity indices, and any other investment representing equity ownership in a company. The fund will primarily invest in common stocks of large cap U.S. companies. The fund considers large-capitalization companies to be those in the capitalization range of the S&P 500 Index. The fund will also utilize a derivatives hedging strategy that seeks to reduce the fund’s volatility and provides protection during equity market drawdowns. Any derivatives that provide exposure to the fund’s investment focus or to one or more market risk factors associated with such investment focus are counted toward the fund’s 80% investment policy. The fund invests primarily in U.S. large-capitalization companies, selected through a fundamental, bottom-up research process to construct a high conviction portfolio. The team will utilize a “margin of safety” approach to identify companies that are trading at a discount to their long-term intrinsic value with an attractive business model and a company-specific catalyst(s) to unlock value.The derivatives hedging strategy is intended to balance upside market participation and downside protection by employing a flexible, actively managed options overlay consisting of: Index Put Spreads: Staggered maturities of Index put spreads, generally on the S&P 500 Index, to provide downside protection. Utilizing a staggered approach attempts to reduce potential risks with a singular hedge period. The put spread exposure is actively managed based on proprietary signals, technical factors, and market dynamics. In normal market environments, the manager will maintain a stable put spread to provide downside equity market protection. In stressed market environments, the manager has the flexibility to lock in hedge gains, reset and adjust the level of protection. The manager utilizes multiple factors in determining periods of market stress. Single-stock covered calls: Selectively written calls on individual equity holdings, with strike selection and maturity based on market conditions, stock-specific factors, and option valuations. Typically, calls are written 5% out-of-the-money with one-month expiry. The discretionary overlay assesses the market environment to determine the attractiveness of selling calls. The fund’s management team has the flexibility to adjust the level of call overwriting based on market conditions. This approach seeks to generate option premium income while managing the extent to which the fund's participation in equity market gains may be limited. During periods of market stress, the team may temporarily reduce the amount of call overwriting. Index calls: In periods of market stress, the manager may elect to purchase call options to capture equity market upside. The fund may, from time to time, selectively purchase call options on an index. When the fund purchases index call options, such options generally will reference the S&P 500® Index. The fund may invest in both exchange traded and over-the-counter (OTC) options. The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. Because ESG factors are considered alongside other relevant factors, the manager may determine that an investment is appropriate notwithstanding its relative ESG characteristics. The fund may invest up to 15% of its net assets in illiquid securities, including securities that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale. The fund also may participate as a purchaser in Initial Public Offerings (IPOs). The fund may also seek to increase its income by lending portfolio securities. Due to the nature of certain of the fund’s investments, the fund may, under certain circumstances, effect a portion or all of creations and redemptions for cash, rather than in-kind securities. The fund is non-diversified, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.

Strategy Narrative [Text Block] The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities included in the fund’s Index, in depositary receipts representing securities included in the fund’s Index and in underlying stocks in respect of depositary receipts included in the fund’s Index.The Index is developed and maintained by Dimensional Fund Advisors LP and is designed to comprise a subset of securities associated with developed markets outside the U.S. and Canada.Eligible securities are generally considered to be those with market capitalizations in the top 85% of the eligible country and the top 90% of all securities in the eligible countries at the time of reconstitution. The selection and weighting of securities in the Index involves a rules-based process that may sometimes be referred to as multifactor investing, factor-based investing, strategic beta, or smart beta. With respect to each country, securities are classified according to their market capitalization, relative price, and profitability. Weights for individual securities are determined by adjusting their free-float adjusted market capitalization weight within the universe of eligible securities so that securities with smaller market capitalizations, lower relative price and higher profitability generally receive an increased weight relative to their unadjusted weight, and vice versa. This process can be summarized as follows: Adjustments for market capitalization: Securities’ weights are generally determined on a country specific basis and based primarily on market capitalization. Within each country, eligible securities are assigned into one of two groups based on size, with the intent of increasing the weights of securities with smaller market capitalizations within the eligible universe and decreasing weights of securities with larger market capitalizations within the eligible universe. Securities in the smaller market capitalization group will have a larger adjustment factor applied to their free-float market capitalization. Securities in the larger market capitalization group will receive a lower adjustment factor. Adjustments for relative price and profitability: Adjustments for relative price and profitability may be implemented within each country. Within each country, securities (other than real estate investment trusts (REITs), or REIT-like entities) are assigned to a relative price group and to a profitability group. REITs and REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests. REITs or REIT-like entities are generally assigned to separate relative price and profitability groups. Relative price adjustment factors are assigned with the intent of increasing the weights of securities with lower relative prices and decreasing the weights of securities with higher relative prices. Similarly, profitability adjustment factors are assigned with the intent of increasing the weights of securities with higher profitability and decreasing the weights of securities with lower profitability. Securities are then weighted after taking into account their free-float, size, relative price and profitability adjustments, subject to a cap of 4% on a single company at the time of reconstitution. The weight of any single company engaged in a securities-related business will be reduced if such company’s weight reaches or exceeds 4.75% between reconstitutions. The Index is reconstituted and rebalanced on a semiannual basis. The fund, using an indexing investment approach, attempts to approximate the investment performance of the Index by investing in a portfolio of securities that generally replicates the Index. The fund may concentrate its investments in a particular country, region, industry or group of industries to the extent that the Index concentrates in a country, region, industry or group of industries. As of June 30, 2026, the following countries are designated as Index-eligible countries: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. The list of designated Index-eligible countries may vary over time. In addition to the countries listed above, the fund may continue to hold investments in countries that are not currently designated as an Index-eligible country, but had been authorized for investment in the past, and may reinvest distributions received in connection with such existing investments in such previously Index-eligible country. The Index may include securities associated with an eligible country, such as, among others: (a) securities of a company that is incorporated and domiciled within an eligible country and that has an issued security that trades on an eligible exchange in an eligible country; (b) securities of a company that derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in an eligible country; (c) securities of a company that holds at least 50% of its assets in an eligible country; (d) securities of a company that has a security denominated in the currency of an eligible country for the purpose of financing operations in that eligible country; (e) securities of companies in eligible countries in the form of depositary shares; or (f) securities that provide financial exposure to and derive their value from securities issued by a company in an eligible country. As a result, the value of the securities may reflect economic and market forces in such other countries or regions as well as in the eligible countries.

Strategy Narrative [Text Block] The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities included in the fund’s Index, in depositary receipts representing securities included in the fund’s Index, and in underlying stocks in respect of depositary receipts included in the fund’s Index.The Index is developed and maintained by Dimensional Fund Advisors LP and is designed to comprise a subset of securities associated with emerging markets, which may include frontier markets (emerging markets in an earlier stage of development).Eligible securities are generally considered to be those with market capitalizations in the top 80% of an eligible country and the top 85% of all securities in eligible countries at the time of reconstitution. The selection and weighting of securities in the Index involves a rules-based process that may sometimes be referred to as multifactor investing, factor-based investing, strategic beta, or smart beta. With respect to each country, securities are classified according to their market capitalization, relative price, and profitability. Weights for individual securities are determined by adjusting their free-float adjusted market capitalization weight within the universe of eligible securities so that securities with smaller market capitalizations, lower relative price and higher profitability generally receive an increased weight relative to their unadjusted weight, and vice versa. This process can be summarized as follows: Adjustments for market capitalization: Securities’ weights are generally determined on a country specific basis and based primarily on market capitalization. Within each country, eligible securities are assigned into one of two groups based on size, with the intent of increasing the weights of securities with smaller market capitalizations within the eligible universe and decreasing weights of securities with larger market capitalizations within the eligible universe. Securities in the smaller market capitalization group will have a larger adjustment factor applied to their free-float market capitalization. Securities in the larger market capitalization group will receive a lower adjustment factor. Adjustments for relative price and profitability: Adjustments for relative price and profitability may be implemented within each country. Within each country, securities (other than real estate investment trusts (REITs), or REIT-like entities) are assigned to a relative price group and to a profitability group. REITs and REIT-like entities are types of real estate companies that pool investors’ funds for investment primarily in income producing real estate or real estate related loans or interests. REITs or REIT-like entities are generally assigned to separate relative price and profitability groups. Relative price adjustment factors are assigned with the intent of increasing the weights of securities with lower relative prices and decreasing the weights of securities with higher relative prices. Similarly, profitability adjustment factors are assigned with the intent of increasing the weights of securities with higher profitability and decreasing the weights of securities with lower profitability. Securities are then weighted after taking into account their free-float, size, relative price and profitability adjustments, subject to a cap of 4% on a single company at the time of reconstitution. The weight of any single company engaged in a securities-related business will be reduced if such company’s weight reaches or exceeds 4.75% between reconstitutions. The Index is reconstituted and rebalanced on a semiannual basis. The fund, using an indexing investment approach, attempts to approximate the investment performance of the Index by investing in a portfolio of securities that generally replicates the Index. The fund may concentrate its investments in a particular country, region, industry or group of industries to the extent that the Index concentrates in a country, region, industry or group of industries. As of June 30, 2026, the following countries are designated as Index-eligible countries: Brazil, Chile, China (including China A-Shares), Colombia, the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Kuwait, Malaysia, Mexico, Peru, the Philippines, Poland, Qatar, Saudi Arabia, South Africa, South Korea, Taiwan, Thailand, Turkey, and the United Arab Emirates. The list of designated Index-eligible countries may vary over time. In addition to the countries listed above, the fund may continue to hold investments in countries that are not currently designated as an Index-eligible country, but had been authorized for investment in the past, and may reinvest distributions received in connection with such existing investments in such previously Index-eligible country. The Index may include securities associated with an eligible country, such as, among others: (a) securities of a company that is incorporated and domiciled within an eligible country and that has an issued security that trades on an eligible exchange in an eligible country; (b) securities of a company that derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in an eligible country; (c) securities of a company that holds at least 50% of its assets in an eligible country; (d) securities of a company that has a security denominated in the currency of an eligible country for the purpose of financing operations in that eligible country; (e) securities of companies in eligible countries in the form of depositary shares; or (f) securities that provide financial exposure to and derive their value from securities issued by a company in an eligible country. As a result, the value of the securities may reflect economic and market forces in such other countries or regions as well as in the eligible countries.

Strategy Narrative [Text Block] The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities that compose the fund’s Index.The Index is developed and maintained by Dimensional Fund Advisors LP and is designed to comprise a subset of securities in the U.S. Universe issued by companies whose market capitalizations are between the 200th and 951st largest U.S. company at the time of reconstitution.The selection and weighting of securities in the Index involves a rules-based process that may sometimes be referred to as multifactor investing, factor-based investing, strategic beta, or smart beta.

Securities in the group of companies with smaller market capitalizations will have their free-float market capitalization adjusted by a larger adjustment factor than securities in the group of companies with larger market capitalizations. Adjustments for relative price and profitability: Adjustments for relative price and profitability are implemented on a sector-by-sector basis. Within each sector, securities (other than real estate investment trusts (REITs)) are assigned to a relative price group and to a profitability group. REITs are generally assigned to separate relative price and profitability groups. Relative price adjustment factors are assigned with the intent of increasing the weights of securities with lower relative prices and decreasing the weights of securities with higher relative prices. Similarly, profitability adjustment factors are assigned with the intent of increasing the weights of securities with higher profitability and decreasing the weights of securities with lower profitability. Relative price and profitability adjustment factors for REITs will generally act to reduce their weight relative to their unadjusted weight in the U.S. Universe. Securities are then weighted after taking into account their free-float, size, relative price and profitability adjustments, subject to a cap of 4% on a single company at the time of reconstitution. The Index is reconstituted and rebalanced on a semiannual basis. The U.S. Universe is defined as a free float-adjusted market-capitalization-weighted portfolio of U.S. operating companies listed on the New York Stock Exchange (NYSE), NYSE American LLC, NASDAQ Global Market, or such other securities exchanges deemed appropriate in accordance with the rules-based methodology that is maintained by Dimensional Fund Advisors LP. This means that the market-capitalization of a particular company within the eligible universe of stocks is adjusted to exclude the share capital of a company that is not considered freely available for trading in the public equity markets. The fund, using an indexing investment approach, attempts to approximate the investment performance of the Index by investing in a portfolio of securities that generally replicates the Index.

Strategy [Heading] <span style="color:#000000;font-family:Arial Narrow;font-size:10pt;font-weight:bold;">Principal investment strategies</span>
Strategy Narrative [Text Block] The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index.Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in preferred stocks and other preferred securities.Preferred stocks and preferred securities include, but are not limited to, convertible preferred securities, corporate hybrid securities, Trust Preferred Securities (defined below), cumulative and non-cumulative preferred stock, and depositary shares of preferred stock. Preferred securities generally pay fixed or adjustable-rate distributions to investors and have preference over common stock in the payment of distributions and the liquidation of a company’s assets, but are generally junior to all forms of the company’s debt, including both senior and subordinated debt. The manager focuses on sector allocation, industry allocation and security selection in making investment decisions and looks to invest in securities that may be undervalued relative to similar securities in the marketplace.Preferred securities held by the fund may have debt and equity characteristics. In addition, certain preferred securities held by the fund may be issued by trusts or other special purpose entities created by companies, such as bank holding companies, specifically for the purpose of issuing such securities (Trust Preferred Securities). The fund may invest up to 20% of its net assets in common stocks or other equity securities that are not considered preferred securities and in debt securities with ratings equivalent to those of the preferred securities in which the fund may invest. Debt securities in which the fund may invest include corporate bonds and high yield securities. In addition, the fund may invest in contingent convertible securities (CoCos). The fund will invest at least 50% of its net assets in preferred securities and other fixed-income securities that are rated investment grade (i.e., at least “Baa3” by Moody’s Investors Service, Inc. (Moody’s) or “BBB–” by S&P Global Ratings (S&P) and Fitch Ratings (Fitch) or by any nationally recognized statistical ratings organization (NRSRO), or in unrated securities determined by the manager to be of comparable credit quality. The fund can invest up to 50% of its net assets in preferred securities and other fixed income securities that are rated below investment grade by either S&P, Fitch, Moody’s or by any NRSRO or in comparable unrated securities. Below investment grade securities must be rated “B” or higher by either S&P, Fitch, Moody’s or by any NRSRO (or determined to be of comparable quality). These investment policies are based on credit quality ratings at the time of acquisition. The fund may invest in common and preferred securities issued by real estate investment trusts (REITs). The fund will concentrate its investments in the group of industries that comprise the utilities and the communication sectors. In addition, the fund will concentrate its investments in the group of industries that comprise the financials sector. Although the fund invests typically in the securities of U.S. issuers, the fund may invest up to 20% of its total assets in securities of corporate and governmental issuers located outside the United States that are traded or denominated in U.S. dollars. The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. Because ESG factors are considered alongside other relevant factors, the manager may determine that an investment is appropriate notwithstanding its relative ESG characteristics. The fund may engage in derivative transactions. Derivatives may be used to reduce risk, obtain efficient market exposure, and/or enhance investment returns, and may include futures contracts on securities and indexes; options on futures contracts, securities, and indexes; interest-rate, foreign currency, and credit default swaps; and foreign currency forward contracts. Due to the nature of certain of the fund’s investments, the fund may, under certain circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities.
