The investment seeks to track the investment results, before fees and expenses, of the ICE BofAML Enhanced Yield 1-5 Year US Broad Bond Index (the "index"). Under normal market conditions, the fund invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in component securities of the index. The index is designed to broadly capture the 1-5 year U.S. investment grade fixed income market, as represented by a modified version of the ICE BofAML 1-5 Year US Broad Market Index.
