The investment seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Morningstar Emerging Markets High Yield Bond Index (the "underlying index"). The fund generally invests at least 80% of its assets in the securities of the underlying index and in investments that provide substantially similar exposure to the securities in the underlying index. The underlying index tracks the performance of the below-investment-grade U.S. dollar-denominated emerging market sovereign and corporate high yield bond market. High yield bonds are also known as "junk bonds." The fund is non-diversified.
