Strategy. The Fund seeks to track the investment results of the MSCI EAFE 100% Hedged to USD Index (the Underlying Index ), which has been developed by MSCI Inc. (the Index Provider or MSCI ) as an equity benchmark for international stock performance, which attempts to mitigate exposure to the currency risk inherent in certain securities included in the Underlying Index by hedging to the U.S. dollar. The Underlying Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE Index. The Underlying Index includes stocks from Europe, Australasia and the Far East and, as of July 31, 2025, consisted of securities from the following 21 developed market countries or regions: … Show more… The Fund seeks to track the investment results of the MSCI EAFE 100% Hedged to USD Index (the Underlying Index ), which has been developed by MSCI Inc. (the Index Provider or MSCI ) as an equity benchmark for international stock performance, which attempts to mitigate exposure to the currency risk inherent in certain securities included in the Underlying Index by hedging to the U.S. dollar. The Underlying Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE Index. The Underlying Index includes stocks from Europe, Australasia and the Far East and, as of July 31, 2025, consisted of securities from the following 21 developed market countries or regions: 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 U.K. ). The Underlying Index includes large- and mid- capitalization companies and may change over time. As of July 31, 2025, a significant portion of the Underlying Index is represented by securities of companies in the consumer goods and services, financials and industrials industries or sectors. The components of the Underlying Index are likely to change over time. The Fund seeks to achieve its investment objective by investing a substantial portion of its assets in the Underlying Fund. As a result, the Funds investment performance is likely to be directly related to the performance of the Underlying Fund. The Funds NAV will change with changes in the value of the Underlying Fund and other instruments in which the Fund invests, subject to the impact of currency hedges, which may cause the Fund to outperform or underperform the return of the Underlying Fund. An investment in the Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Fund and in currency hedges. The Underlying Fund invests in non-U.S. securities without implementing a hedge of the local currency risk. This strategy is subject to additional risks, as described in this Prospectus and the Funds SAI. BFA is not required to invest the Funds assets in, or allocate any particular percentage of the Funds assets to, any particular underlying fund, including the Underlying Fund. Components of the Underlying Index include equity securities and currency forward contracts both deliverable and nondeliverable designed to hedge non-U.S. currency fluctuations against the U.S. dollar. The notional exposure to currency forward contracts (both deliverable and nondeliverable) generally will be a short position that hedges the currency risk of the equity portfolio. The index is 100% hedged to the U.S. dollar by selling each foreign non-U.S. dollar currency forward at the one-month forward weight in order to create a hedge against fluctuations in the relative value of the non-U.S. dollar component currencies in relation to the U.S. dollar. A currency forward contract is an over-the-counter ( OTC ) contract between two parties to buy or sell a specified amount of a specific currency in the future at an agreed-upon exchange rate. The hedge is reset monthly by MSCI and is not adjusted intra-month based on movement in the value of the component equity securities and/or currencies. The Underlying Index may therefore be slightly over-hedged (if equity values decline) or under-hedged (if the equity values increase) between the month-end rebalances. The Underlying Index is designed to have higher returns than an equivalent unhedged investment when the non-U.S. dollar component currencies are weakening relative to the U.S. dollar and appreciation in some of the non-U.S. dollar component currencies does not exceed the aggregate depreciation of the others. Conversely, the Underlying Index is designed to have lower returns than an equivalent unhedged investment when the non-U.S. dollar component currencies are rising relative to the U.S. dollar. In order to track the hedging component of the Underlying Index, the Fund enters into currency forward contracts as described above. While this approach is designed to minimize the impact of currency fluctuations on Fund returns, it does not necessarily eliminate the Funds exposure to the non-U.S. dollar component currencies. The return of the currency forward contracts may not perfectly offset the actual fluctuations in value between the non-U.S. dollar component currencies and the U.S. dollar. The Fund may also use non-deliverable forward ( NDF ) contracts to execute its hedging transactions. An NDF contract is a contract where there is no physical settlement of two currencies at maturity. Rather, based on the movements of the currencies and the contractually agreed-upon exchange rate, a net cash settlement will be made by one party to the other in U.S. dollars. BFA uses an indexing approach to try to achieve the Funds investment objective. The Fund does not try to beat the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies. BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. Representative sampling is an indexing strategy that involves investing in a representative sample of securities or other instruments that collectively has 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 and the Underlying Fund may not hold all of the components of the applicable underlying index and may hold certain securities or other instruments that are not included in the applicable underlying index. The Fund generally will invest at least 80% of its assets in the component securities (including indirect investments through the Underlying Fund) and other instruments of the Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of its Underlying Index ( i.e. , depositary receipts representing securities of the Underlying Index) and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund. 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 MSCI, which is ? independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities ? and currency forwards in 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.
