The Fund generally will invest at least 90 percent of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, S&P Dow Jones Indices LLC (the Index Provider) compiles, maintains and calculates the Underlying Index, which is designed to track the performance of approximately 90 growth stocks in the S&P SmallCap 600 Index (the Parent Index) with relatively high quality and value composite scores, which are computed as described below. The Parent Index measures the performance of the small-cap segment of the U.S. equity market and is comprised of approximately 600 securities. The Fund defines small-capitalization companies as companies whose securities are included in the Parent Index. As of the date of this prospectus, companies eligible for inclusion in the Parent Index had a market capitalization between dollar 900 million and dollar 5.8 billion at the time of their inclusion in the Parent Index; these market capitalization guidelines may fluctuate depending on the overall level of equity markets.
