The investment seeks to track the price and yield performance of its underlying index, the IQ Enhanced Core Plus Bond U.S. Index. The fund is a "fund of funds" which means it invests, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the investments included in its underlying index, which includes underlying funds. The underlying index seeks to outperform the U.S. dollar-denominated taxable fixed income universe by using a combination of short- and long-term momentum to overweight and underweight various sectors of the investment grade and high yield fixed income securities market.
