The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities included in the funds Index, in depositary receipts representing securities included in the funds Index, and in underlying stocks in respect of depositary receipts included in the funds Index. The Index is developed and maintained by Dimensional Fund Advisors LP and is designed to comprise a subset of securities associated with emerging markets, which may include frontier markets (emerging markets in an earlier stage of development). Eligible securities are generally considered to be those with market capitalizations in the top 80% of an eligible country and the top 85% of all securities in eligible countries at the time of reconstitution. The selection and weighting of securities in the Index involves a rules-based process that may sometimes be referred to as multifactor investing, factor-based investing, strategic beta, or smart beta. With respect to each country, securities are classified according to their market capitalization, relative price, and profitability.
