Strategy. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in U.S. listed common stock of large-, mid- and small-capitalization technology companies, as defined by a proprietary classification system ( Evolved Technology Sector ), while targeting increased exposure to U.S. companies with a greater proportion of technological capabilities, revenues, and production in the U.S. and select global markets relative to the proprietary classification system. The Evolved Technology Sector classification process, which uses data analysis tools consisting, in part, of machine learning, natural language processing ( NLP ) and clustering algorithms to allocate companies to one or more sectors according to a proprietary classification system, is forward looking and evolves as … Show more… The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in U.S. listed common stock of large-, mid- and small-capitalization technology companies, as defined by a proprietary classification system ( Evolved Technology Sector ), while targeting increased exposure to U.S. companies with a greater proportion of technological capabilities, revenues, and production in the U.S. and select global markets relative to the proprietary classification system. The Evolved Technology Sector classification process, which uses data analysis tools consisting, in part, of machine learning, natural language processing ( NLP ) and clustering algorithms to allocate companies to one or more sectors according to a proprietary classification system, is forward looking and evolves as companies evolve. The eligible universe of securities that are part of the classification process includes U.S. listed common stock of large-, mid- and small-capitalization companies. Based on data and information in the companys public filings ( e.g ., regulatory filings), a company is classified in one or more of the twelve defined sectors (each an Evolved Sector ). Currently these public filings consist of several years of a companys 10-Ks and S-1s (if no 10-Ks are available). The Fund uses additional screens to include companies that are related to technology, technology infrastructure and technology security. The Fund's allocation rules additionally utilize proprietary data to target increased exposure to U.S. companies with a greater proportion of technological capabilities, revenues, and production in the U.S. and select global markets relative to the Evolved Technology Sector ( Technology Independence Score ). Select global markets alongside the U.S. are identified using a proprietary classification system which seeks to identify markets where the ability of U.S. companies to access supply chains, infrastructure, and other resources relevant to U.S. companies product and service delivery is expected to remain relatively more resilient to potential geopolitical headwinds. While the Fund is actively managed, the Fund generally allocates its investments to securities of its Evolved Sectors and the additional companies related to technology, technology infrastructure and technology security, on a market capitalization basis (based on the available free floating capitalization) while modifying allocations to companies based on their Technology Independence Score. The Evolved Sector classification system allows for a company to be classified into multiple sectors rather than being assigned solely to a single sector. For the Evolved Sectors, the market capitalization of a single company will be allocated proportionally based on the one or more Evolved Sectors in which the company is classified. This reflects the multi-dimensional nature of these companies. Evolved Sector constituents are expected to evolve dynamically over time to reflect changing business models. The constituents in the Evolved Sectors will be reviewed and updated at least annually. BFA may exercise discretion in managing the classification process in limited instances. For example, a company may be excluded (or its inclusion limited) from an Evolved Sector, in part or whole, most commonly in response to position limit restrictions, limited liquidity of a particular security or the fit of a particular company in the Fund. This is different from traditional classification systems that typically will assign a company only to one sector and tend to group companies together on the basis of backward looking metrics like revenue. The Fund will not provide the same returns as a fund that tracks the information technology sector as traditionally defined by other classification systems and as a result may not be appropriate for an investor seeking the same exposure as the information technology sector as defined by such classification systems. In certain situations or market conditions, the Fund may temporarily depart from its normal investment process, provided that the alternative, in the opinion of BFA, is consistent with the Funds investment objective and is in the best interest of the Fund. The Fund has no stated minimum holding period for investments and may buy or sell securities whenever Fund management sees an appropriate opportunity. The Fund may engage in active and frequent trading of its investments. As of July 31, 2025, there were twelve Evolved Sectors: Consumer Staples, Discretionary Spending, Energy, Financials, Healthcare Staples, Industrials, Innovative Healthcare, Media and Entertainment, Real Estate, Technology, Telecommunications and Utilities.Sector classifications are reviewed on a quarterly basis and may evolve over time. The Fund will hold common stock of those companies that fall into the Technology Evolved Sector, as well as additional companies that are related to technology, technology infrastructure and technology security, while targeting increased exposure to companies with higher Technology Independence Scores relative to the Technology Evolved Sector. Companies in the Technology Evolved Sector have economic characteristics that have been historically correlated with companies traditionally defined as technology companies. The Fund may also invest in other securities, including but not limited to, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates. The Fund's 80% investment policy may be changed by the Fund's Board of Trustees (the Board ) upon 60 days' notice to shareholders. The Fund is an actively managed exchange-traded fund ( ETF ) and does not seek to replicate the performance of a specified index and may have a higher degree of portfolio turnover than such index funds. The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received). Industry Concentration Policy. The Fund will concentrate its investments ( i.e., hold 25% or more of its total assets) in an industry or group of industries that constitute the technology sector. 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. Industry concentration designations are based on output of the classification methodology referenced above. Show less
