The investment seeks investment results that closely correspond, before fees and expenses, to the performance of the Russell 1000 Diversified Factor Index. The fund will invest at least 80% of its assets in securities included in the underlying index. The underlying index is comprised of U.S. equity securities selected to represent a diversified set of factor characteristics, originally developed by the adviser. Holdings in the underlying index are selected by the index provider primarily from the constituents of the Russell 1000 Index, a larger Russell index, which is comprised of large- and mid-cap equity securities in the United States.
