The Fund seeks to track the investment results of the MSCI Emerging Markets Index (the Underlying Index), which is designed to measure equity market performance in the global emerging markets. As of August 31, 2023, the Underlying Index consisted of securities from the following 24 emerging market countries: Brazil, Chile, China, Colombia, 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 Underlying Index includes large- and mid-capitalization companies and may change over time. As of August 31, 2023, a significant portion of the Underlying Index is represented by securities of companies in the financials and technology industries or sectors. The components of the Underlying Index are likely to change over time. BFA uses an indexing approach to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to beat the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.
