Strategy. The Fund generally will invest at least 90% of its total assets in the securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, FTSE Russell (the Index Provider) compiles, maintains and calculates the Underlying Index, which is comprised of securities in the Russell 1000 Index (the Russell 1000) that exhibit upward price momentum and good relative valuation. The Underlying Index is a subset of the Russell 1000, which is designed to measure the performance of the large-cap segment of the U.S. equity market and consists of the stocks of the largest 1,000 U.S. companies by market capitalization.

Strictly in accordance with its guidelines and mandated procedures, FTSE Russell (the Index Provider) compiles, maintains and calculates the Underlying Index, which is comprised of securities in the Russell 1000 Index (the Russell 1000) that exhibit upward price momentum and good relative valuation. The Underlying Index is a subset of the Russell 1000, which is designed to measure the performance of the large-cap segment of the U.S. equity market and consists of the stocks of the largest 1,000 U.S. companies by market capitalization. The Index Provider selects constituent securities for the Underlying Index by applying a three-step screening process (based on a securitys earnings, valuation and momentum) to all securities in the Russell 1000. First, the Index Provider excludes securities with zero or negative earnings over the past 12 months. Second, the Index Provider screens for value stocks. A value stock tends to trade at a lower price than the price at which such stock would be expected to trade given the fundamentals of its company (e.g., dividends, earnings and sales), and thus may be considered undervalued by investors. Third, the Index Provider screens for securities with greater positive price momentum. In general, momentum is an economic concept that describes the tendency for recent changes in a stocks price to persist for some time into the future. The trend in the change of a stocks price may be upward (positive momentum) or downward (negative momentum). A positive momentum style of investing emphasizes investing in stocks that have had better recent performance compared to other stocks, on the expectation that such a positive trend will continue because of the stocks momentum in the market. Constituent securities in the Underlying Index are equally weighted. The Underlying Index also may include securities of mid-cap issuers. Therefore, due to the equal weighting methodology of the Underlying Index, the Fund may have greater exposure to mid-cap issuers than would be the case if the Underlying Index used a traditional capitalization-weighted methodology. As of October 31, 2022, the Underlying Index was comprised of 698 securities with market capitalizations ranging from $619.77 million to $2.48 trillion. The Fund employs a full replication methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. Show less
