Strategy [Heading]	Principal Investment Strategies
Strategy Narrative [Text Block]	The Fund seeks to track the investment results of the Dow Jones Emerging Markets Select Dividend Index (the “Underlying Index”), which is provided by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index measures the performance of 100 leading dividend-paying emerging market companies, selected according to indicated annual dividend (“IAD”) yield, subject to screening and buffering criteria and weighting constraints. IAD yield is defined as a stock’s IAD (not including any special dividends) divided by its price. The starting universe for the Underlying Index is the S&P Emerging BMI, excluding real estate investment trusts. To be eligible for the Underlying Index, issuers must have paid dividends in each of the previous three years, and their securities must have (i) a non-negative trailing 12-month earnings per share; (ii) an IAD yield greater than 0%; (iii) a float-adjusted market capitalization of at least $250 million; and (iv) a three-month average daily trading value of at least $3 million for new constituents, or at least $1.5 million for current constituents. Eligible securities are ranked by IAD yield, and the top 100 stocks are selected as index constituents. No more than 30 stocks can be selected from any single country, subject to certain buffers. The Underlying Index is reconstituted annually with constituent weights determined based on tilted IAD yield, which is calculated by multiplying the constituent’s IAD yield (capped at 15%) by the square root of its float market capitalization. The capping methodology also limits the weight of individual securities to 10%, the aggregate weight of constituents within each country of domicile to 25%, and the aggregate weight of constituents within each Global Industry Classification Standard sector to 30%. The Underlying Index is reviewed daily based on each constituent’s weight. Daily capping is performed if the aggregate weight of constituents with an individual weight greater than 4.8% exceeds 24% of the Underlying Index’s total weight. If that threshold is breached, the current constituent weights are recapped, with weights of individual securities capped at 10% and the aggregate weight of stocks with an individual weight greater than 4.5% capped at 22.5% of the Underlying Index’s total weight. IAD yields and tilted yield weights are not recalculated if the capping thresholds are breached throughout the year. A freeze period on the daily capping is implemented during the annual index reconstitution. As of April 30, 2026, the Underlying Index consisted of issuers in the following countries: Brazil, China, Colombia, Czech Republic, Greece, India, Indonesia, Malaysia, Mexico, Poland, Qatar, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates. The Underlying Index may include large-, mid- and small-capitalization companies. As of April 30, 2026, a significant portion of the Underlying Index was represented by securities of companies in the financials, industrials and materials industries or sectors. The components of the Underlying Index are likely to change over time. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund. BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities or other instruments intended to collectively have an investment profile similar to that of an applicable underlying index. The instruments selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the components of the Underlying Index. The Fund may use derivatives to gain or reduce exposure to the components of the Underlying Index or exposure to one or more market risk factors associated with such components. Subject to the limits described herein, the Fund may purchase and hold cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, and may also purchase and hold instruments not included in the Underlying Index when BFA believes that such instruments will help the Fund track the performance of the Underlying Index over time, including in light of expected liquidity or trading costs, anticipated additions to or deletions from the Underlying Index, or other reasons as determined by BFA. In accordance with Rule 35d-1 under the Investment Company Act of 1940, as amended (the “1940 Act”), under normal circumstances, the Fund will not invest less than 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in components of its Underlying Index. Investments in derivatives and other investments will be counted toward the Fund's 80% investment policy to the extent that they provide exposure to the components of its Underlying Index or exposure to one or more market risk factors associated with such components. The Fund's 80% investment policy may be changed by the Company's Board of Directors (the “Board”) upon 60 days' notice to shareholders. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received). The Underlying Index is sponsored by SPDJI, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the components of the Underlying Index and publishes information regarding the market value of the Underlying Index. Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.
