The Advisor is the index provider for the Underlying Index. The Underlying Index seeks to provide exposure to innovative companies by investing in the equities of U.S. large cap companies whose research and development (R&D) indicates a commitment to innovation and a focus on long-term growth spending. R&D spending includes expenditures on R&D intended for the development of concepts or ideas for products or services by which the issuer can increase revenues. The Underlying Index includes securities of large-capitalization companies that trade in the U.S. As of June 30, 2025, the market capitalization range of the Underlying Index was approximately $6.4 billion to $3.9 trillion. As of June 30, 2025, the primary sectors within the Underlying Index were information technology, health care, and communication services. The Fund invests, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the investments included in its Underlying Index. The securities eligible for inclusion in the Underlying Index are those securities included in the Russell 1000 Index. The Underlying Index uses a screening process to exclude companies in sectors where R&D investments have historically had less impact on a companys performance, and to identify companies that have exhibited a strong commitment for long term growth by reinvesting in R&D. The Underlying Index then ranks companies based on an analysis of a companys R&D spending to sales and return on invested capital. R&D spending to sales measures a companys investment in R&D as a percentage of its total sales, and companies are ranked based on their score within their sector. Return on invested capital measures how efficiently a company deploys capital to generate profits. The 100 highest ranked companies are included for selection in the Underlying I ndex. Securities selected for inclusion in the Underlying Index are weighted based on their market capitalization ranking , subject to a maximum weight at the time of rebalance of the greater of (i) 5%, or (ii) the weight of a components issuer in the Russell1000 Growth Index plus 2% (Component Weight Cap). To the extent a component would exceed the Component Weight Cap at the time of rebalance, the excess percentage is allocated proportionately among the other components of the Underlying Index. Additionally, at the time of rebalance, the Underlying Index limits the maximum weight of all securities within each sector to the greater of (i) 20%, or (ii) the weight of the sector in the Russell 1000 Growth Index plus 5% (Sector Weight Cap). To the extent the securities within a sector would exceed the Sector Weight Cap at the time of rebalance, the excess percentage is allocated proportionately among securities within the other sectors of the Underlying Index. The Underlying Index is reconstituted and rebalanced quarterly. The Fund generally will invest in all of the securities that comprise its Underlying Index in proportion to their weightings in the Underlying Index. The Fund has adopted a policy that it will, under normal circumstances, invest at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in securities of U.S. large-capitalization issuers. The Underlying Index may include as a component one or more ETFs advised by the Advisor (Affiliated ETFs) and the Fund will typically invest in any Affiliated ETF included in the Underlying Index. The Fund also may invest in Affiliated ETFs that are not components of the index if such an investment will help the Fund track the Underlying Index. Show less
