The investment seeks to provide investment results that closely correspond, before expenses, to the performance of the Nasdaq US Shareholder Yield Index. Under normal circumstances, the fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies that compose the index at the time of purchase. The index uses a quantitative model designed to identify equity securities (including value stock) of mid- to large-capitalization companies in the Nasdaq US Large Mid Cap Index (the parent index) that exhibit higher degrees of shareholder yield.
