The fund targets large- and midcap companies from the developed markets having positive ESG traits and specifically screens out firms that have an exposure to fossil fuels. Starting with the companies from the MSCI World ESG Leaders Index, the fund applies a series of exclusionary screens which eliminates: i) companies that generate less than 30% of its revenue from social and environmental themes, as determined by MSCIs Sustainable Impact Metrics, ii) firms that faced ESG controversies, as defined by an MSCI Controversy Score of 0, 1 and 2, and iii) companies that have proved and probable coal and/or oil and natural gas reserves used for energy purposes. At each quarterly rebalance, constituents are market-cap-weighted and are constrained such that each individual sector and security is capped at 25% and 5% weights, respectively. The fund is currency hedged for CAD investors. Prior to April 18, 2019, the fund was called CI First Asset MSCI World ESG Impact ETF.
