COLUMBIA SUSTAINABLE GLOBAL EQUITY INCOME ETF (ESGW) Exchange: NYSE ARCA

DELISTED - The Fund uses an indexing investment approach that seeks to replicate the performance of the Index. The Fund invests at least 80% of its assets in the component securities of the Index and depositary receipts representing such securities (or if depositary receipts are component securities of the Index, then underlying stocks of such depositary receipts). The Index is owned and calculated by MSCI Inc. (MSCI or the Index Provider). The Index was developed by MSCI with input from Columbia Management Investment Advisers, LLC (the Investment Manager). The Index, which typically holds common stocks and depositary receipts, was constructed to provide exposure to U.S. and foreign (developed market) large- and mid-cap companies (located in developed markets) that are believed to offer sustainable levels of income, as well as total return opportunity. The Index is comprised of a subset of 200 companies within the MSCI World Index. The Index was designed to reflect the performance of the top 200 U.S. and foreign large- and mid-cap companies (located in developed markets) within the MSCI World Index. The Index reflects a combination of the Beta Advantage® Sustainable U.S. Equity Income 100 Index (the U.S. Component) and the Beta Advantage® Sustainable International Equity Income 100 Index (the International Component) in a single composite index. The U.S. Component: with a starting point of the MSCI USA Index, the U.S. Component was designed to reflect the performance of the top 100 U.S. large- and mid-cap companies, excluding real estate investment trusts (REITs). The U.S. Component typically includes common stocks. The International Component: with a starting point of the MSCI World ex USA Index, the International Component was designed to reflect the performance of the top 100 foreign (developed markets of at least three countries other than the U.S.) large- and mid-cap companies (excluding REITs). The International Component typically includes common stocks and depositary receipts. Each of the U.S. Component and the International Component (collectively, the Components) are constructed through the application of systematic, rules-based methodologies applied by MSCI that ranks and weights companies according to a composite factor score that focuses on security dividend yield, dividend growth, and cash-based dividend coverage ratio factors. MSCI also screens companies for "sustainability" through the application of its Environmental, Social and Governance (ESG) rating methodology that is designed to exclude companies with unfavorable corporate ESG practices. The securities within each Component are weighted based on the overall composite factor scores and dividend yield. The Index and the Components are rebalanced on a quarterly basis in February, May, August and November. At each rebalancing, the weights of the U.S. Component and the International Component within the Index are set to match the U.S. and non-U.S. (International) weights within the MSCI World Value Index, respectively. As such, the Index's holdings in U.S. companies and non-U.S. companies are established by rule methodology, according to their weightings in the MSCI World Value Index. At January 31, 2020, the MSCI World Value Index held 61.78% in U.S. companies and 38.22% in non-U.S. companies. The Fund uses a replication strategy to track the performance of the Index, whereby the Fund invests in or has investment exposure to substantially all of the component securities of the Index in approximately the same proportions as in the Index. However, under various circumstances, including circumstances under which it may not be possible or practicable to purchase all of the securities in the Index, or in the same weightings, the Fund may purchase or have investment exposure to a sample of the securities in the Index in proportions expected to replicate generally the performance of the Index as a whole. There may also be instances in which the Fund may overweight (or underweight) an Index holding, purchase (or sell) instruments not in the Index as a substitute for one or more securities in the Index or utilize various combinations of other available investment techniques in seeking to replicate the performance of the Index. The Fund may sell securities or other holdings that are represented in the Index or purchase securities or make other investments that are not yet represented in the Index in anticipation of their removal from or addition to the Index by MSCI. The Investment Manager does not invest the Fund’s assets based on its view of the investment merits of a particular security or company, nor does it conduct fundamental investment research or analysis, or seek to forecast or otherwise consider market movements, conditions or trends in managing the Fund’s assets. The Fund pursues its investment objective of correlating performance with the Index regardless of market conditions and does not to take defensive positions. The methodology applied by MSCI to select Index holdings and weightings does not set limits on sector or industry exposures. To the extent the Index is concentrated in a particular sector or industry, the Fund will necessarily be concentrated in that sector or industry. As of October 31, 2019, the Index (and therefore the Fund) was concentrated in the industrials sector. The Fund may buy shares of Ameriprise Financial, Inc. (the Investment Manager’s parent company), if included in the Index, subject to certain restrictions.
