The investment seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Morningstar Emerging Markets Corporate Bond Index (the "underlying index"). The fund generally invests at least 80% of its assets in securities of the underlying index and in depositary receipts representing securities of the underlying index. The underlying index tracks the performance of the U.S. dollar-denominated emerging market corporate bond market. The fund is non-diversified.
