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 uses a screening process to exclude companies in sectors where R&D investments have historically had less impact on a company's 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 company's R&D spending to sales and return on invested capital. R&D spending to sales measures a company's 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 Index.
