The investment seeks to track the investment results of the MSCI USA Enhanced Value Index composed of U.S. large- and mid-capitalization stocks with value characteristics and relatively lower valuations. The fund generally will invest at least 90% of its assets in the component securities of the underlying index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents. The index is based on a traditional market capitalization-weighted parent index, the MSCI USA Index (the parent index). The parent index includes U.S. large- and mid- capitalization stocks.
