The fund, using a passive or indexing investment approach, seeks investment results that correspond generally to the performance, before fees and expenses, of the Underlying Index, which is designed to track the equity market performance of companies in the United States selected on the investment style criteria (factors) of quality, value, momentum, low volatility and size. The companies eligible for the Underlying Index are derived from its starting universe, the Russell 1000 Index, which is comprised of large-cap equity securities from issuers in the United States. The index provider, Frank Russell Company (Index Provider), selects companies for the Underlying Index using a proprietary rules-based multi-factor selection and weighting process designed to increase the Underlying Indexs exposure, relative to the starting universe.
