The Underlying Index may include large- or mid-capitalization companies. With 1,395 constituents as of February 28 , 2025 , the Underlying Index covers approximately 85% of the free float-adjusted market capitalization in each country. The components of the Underlying Index, and the degree to which these components represent certain industries, may change over time. The Subadviser generally 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 that collectively has an investment profile similar to that of the Underlying Index. The securities 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 the Underlying Index. The Fund generally invests at least 90% of its assets, plus the amount of any borrowing for investment purposes, in securities of the Underlying Index and in depositary receipts representing securities 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.
