The investment seeks to track the investment results (before fees and expenses) of the S&P 500 Enhanced Value Index (the underlying index). The fund generally will invest at least 90% of its total assets in the securities that comprise the underlying index. The underlying index is designed to track the performance of approximately 100 stocks in the S&P 500® Index that have the highest value score, which the index provider calculates based on fundamental ratios of a company's stock. A value stock tends to trade at a lower price relative to such fundamentals and thus may be considered undervalued by investors.
