The Fund seeks to track the investment results of the MSCI Emerging Markets 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 companies that have favorable environmental, social and governance (ESG) characteristics (as determined by the Index Provider), while exhibiting risk and return characteristics similar to those of the MSCI Emerging Markets Index (the Parent Index). The Index Provider begins with the Parent Index and excludes securities of companies involved in the business of tobacco, companies involved with controversial weapons, producers and retailers of civilian firearms, companies involved in certain fossil fuels-related activity such as the production of thermal coal, thermal coal-based power generation and extraction of oil sands based on revenue or percentage of revenue thresholds for certain categories (e.g. $20 million or 5%) and categorical exclusions for others (e.g. controversial weapons). The Index Provider also excludes companies that are directly involved in very severe, ongoing business controversies (in each case as determined by the Index Provider), and then follows a quantitative process that is designed to determine optimal weights for securities to maximize exposure to securities of companies with higher ESG ratings, subject to maintaining risk and return characteristics similar to the Parent Index.
