The Fund seeks to track the investment results of the MSCI USA Growth Extended ESG Focus Index (the Underlying Index), which has been developed by MSCI Inc. (the Index Provider or MSCI). The Underlying Index is an optimized equity index designed to reflect the equity performance of U.S. companies that exhibit growth characteristics as well as positive environmental, social and governance (ESG) characteristics, as determined by the Index Provider, and risk and return characteristics similar to those of the MSCI USA Growth Index (the Parent Index). The Parent Index includes U.S. large- and mid-capitalization stocks that generally represent approximately 50% of the free float-adjusted market capitalization of the MSCI USA Index and that are identified by MSCI as exhibiting overall growth style characteristics. MSCI uses five variables to identify growth style securities: long-term forward earnings per share (EPS) growth rate, short-term forward EPS growth rate, current internal growth rate, long-term historical EPS growth trend and long-term historical sales per share growth trend.
