EFIV is designed to select companies from the S&P 500 Index that meet certain ESG characteristics, while maintaining the same risk and return as the Index. Companies are identified using an exclusionary screening based on ESG risks rating by Sustainalytics, UNGC score by Arabesque, and S&P DJI ESG Score by SAM. The composite result determines the index holdings. As such, excluded companies are those that have (1) tobacco- and controversial weapons-related involvement (2) UNGC score in the bottom 5% of all UNGC-scored companies globally, and (3) S&P DJI ESG score within the worst 25% from each GICS industry group. The remaining companies are ranked in decreasing order based on their S&P DJI ESG score, with the securities selected representing the top 75% of market capitalization within each industry group. The index is rebalanced and reconstituted annually, on the last business day in April.
