To pursue its objective, The Fund seeks to track the investments results of the MSCI USA Choice ESG Screened Index (the Underlying Index), which has been developed by MSCI Inc. (the Index Provider or MSCI). The Underlying Index is a free float-adjusted market capitalization-weighted index that is designed to reflect the equity performance of large- and mid-capitalization U.S. companies with favorable environmental, social and governance (ESG) ratings (as determined by MSCI ESG Research LLC (MSCI ESG Research)) while applying extensive screens, including removing fossil fuel exposure. MSCI begins with the MSCI USA Index (the Parent Index) and selects companies with favorable ESG ratings while excluding securities of companies involved in adult entertainment, alcohol, gambling, tobacco, genetic engineering, controversial weapons, nuclear weapons, civilian firearms, conventional weapons, palm oil, private prisons, predatory lending, and nuclear power based on revenue or percentage of revenue thresholds for certain categories (e.g., dollar 500 million or 50 percent) and categorical exclusions for others (e.g., nuclear weapons)..
