FlexShares ESG & Climate US Large Cap Core Index Fund (FEUS) is an exchange-traded fund that seeks investment results corresponding generally to the price and yield performance, before fees and expenses, of the Northern Trust ESG & Climate US Large Cap Core Index. Launched on September 20, 2021, and domiciled in the United States, the fund employs a representative sampling strategy to track its underlying index, which constructs a universe of U.S. large capitalization companies exhibiting strong environmental, social, and governance (ESG) characteristics, including climate-focused metrics such as weighted average carbon intensity and sustainable impact solutions exposure. Managed by Northern Trust Investments with a low net expense ratio of 0.09%, FEUS primarily invests in U.S. equities across sectors like technology (approximately 34%), financial services (14%), and consumer cyclical (11%), with top holdings including NVIDIA Corp., Microsoft Corp., Apple Inc., Amazon.com Inc., and Alphabet Inc.; cash holdings comprise about 0.7%, and non-U.S. stock exposure remains minimal at under 0.2%. The fund targets investors seeking core large-cap exposure aligned with ESG and climate values, offering capital appreciation through a blend investment style in the large blend Morningstar category, with total net assets around $76 million as of recent data. Headquartered through its sponsor FlexShares (a Northern Trust brand) in Chicago, Illinois, FEUS operates exclusively in U.S. markets with no reported subsidiaries or parent fund relationships. Recent developments include a manager update in March 2025 with the addition of Shivani Shah alongside existing managers Steven Santiccioli, Robert Anstine, and Brendan Sullivan, alongside steady assets under management growth to approximately $76 million and an ex-dividend date in June 2025 reflecting ongoing dividend distributions of about 1.18% yield; no major acquisitions, partnerships, funding rounds, or strategic shifts have been announced for the fund in the last 1-2 years.
