BKEM provides exposure to large- and mid-cap equities from emerging market countries. The fund tracks an index of securities issued by emerging market companies listed on a developed or emerging market exchange that meet tradability and foreign investment limitation requirements. In determining emerging market exposure, the index evaluates a companys primary listing, incorporation, domicile, and risk. The fund ranks securities by market cap and selects the top 85% of each emerging market country. The index rebalances semi-annually in May and November. Prior to Nov. 15, 2023, the fund tracked the Morningstar Emerging Markets Large Cap Index.
