ESGB uses an active strategy to construct a portfolio that meets the subadvisors ESG criteria. Economic cycle analysis, credit quality and interest rate trends are first used to determine what portion of the fund will be given to each industry or type of security. The fund then uses its proprietary ESG analysis to assign each issuer an environmental, social, and governance score based on factors deemed most material to that asset class and peer group. Next, the fund scores issuers as outperforming, average, or underperforming within each of the ESG factors and combines these scores on an equal basis to determine an issuer's overall score. Historical trends in an issuers score and opportunities where a company has improved its ESG practices are also considered. Finally, a security is selected if it has a score of at least average, or if the issuer has demonstrated a trend of improving scores. Prior to Aug. 28, 2024, the fund name was branded under IndexIQ.
