Legg Mason Emerging Markets Diversified Core ETF seeks to track the investment results of an index composed of publicly traded equity securities in emerging markets. The QS DBI Emerging Markets Diversified Index (the Index ) seeks to provide exposure to equity securities in emerging markets and is based on a proprietary methodology created and sponsored by QS Investors, LLC ( QS ). The Index is composed of equity securities in emerging markets that are included in the MSCI Emerging Markets Index. The proprietary rules-based process initially groups this universe of securities into multiple investment categories based on geography and sector. Within each of these investment categories, securities are weighted by market capitalization. The process then combines those investment categories with more highly correlated historical performance into a smaller number of clusters. A cluster is a group of investment categories based on geography and sector that have demonstrated a tendency to behave similarly (high correlation). Thereafter, each of these clusters is equally weighted in the Index to produce a highly diversified portfolio. QS anticipates that the number of component securities in the Index will range from 700 to 800 from approximately 21 countries, including Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, and Turkey. The Index may include large, medium and small capitalization companies. The components of the Index, and the degree to which these components represent certain countries and sectors, may change over time. The Index s components are reconstituted annually and rebalanced quarterly.
