The Fund offers the potential for enhanced yield with the risk and credit quality profile of the broad U.S. investment-grade bond market. Rather than weighting by market cap, the strategy uses a rules-based methodology that allocates higher weights to securities and sectors that have the potential for higher yield, while maintaining comparable risk. The Fund invests primarily in U.S. government securities, debt securities issued by U.S. corporations, residential and commercial mortgage-backed securities, asset-based securities and U.S. dollar-denominated debt securities issued by non-U.S. governments and corporations. The Fund seeks to track the investment results, before fees and expenses, of the ICE BofA Enhanced Yield U.S. Broad Bond Index.
