Fund Description: Columbia Sustainable International Equity Income ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the Columbia ETF Trust I, an open-end investment management company. INVESTMENT OBJECTIVE: The Columbia Sustainable International Equity Income ETF seeks investment results that, before fees and expenses, closely correspond to the performance of the Beta Advantage Sustainable International Equity Income 100 Index. INDEX DESCRIPTION: The Beta Advantage Sustainable International Equity Income 100 Index is comprised of a subset of 100 companies within the MSCI World ex USA Index. Starting with the MSCI World ex USA Index, the Index was designed to reflect the performance of the top 100 (developed markets) foreign large- and mid-cap companies (excluding real estate investment trusts) ranked and weighted according to a composite factor score determined through the application of a systematic, rules-based methodology applied by MSCI, the Index Provider. This methodology 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 Index component securities are weighted based on the overall composite model scores and dividend yield. The Index is rebalanced on a quarterly basis in February, May, August and November. FUND STRATEGY: 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. 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. FUND MANAGEMENT: Columbia Management Investment Advisers, LLC serves as the investment manager to the Fund.
