- AMG GW&K ESG Bond Fund - Class I (MGBIX) is a mutual fund that seeks total return through a combination of current income and capital appreciation by investing primarily in ESG-screened fixed income securities. The fund offers exposure to investment-grade corporate bonds, U.S. government and agency securities, mortgage-backed securities, asset-backed securities, and high-yield bonds, all selected through rigorous environmental, social, and governance (ESG) criteria including carbon emissions analysis, diversity metrics, and sustainable business practices; it maintains a portfolio duration typically between 4-7 years with an average credit quality of A or higher. Managed by GW&K Investment Management LLC, a subsidiary of Affiliated Managers Group, Inc. (AMG), the fund targets institutional and high-net-worth investors seeking sustainable fixed income strategies and operates globally with primary focus on U.S. dollar-denominated securities across North America, Europe, and emerging markets. Founded in 2018 and headquartered in Boston, Massachusetts, the fund benefits from GW&K's expertise in bottom-up fundamental analysis integrated with proprietary ESG research. AMG GW&K ESG Bond Fund - Class I features a minimum initial investment of $1 million, low expense ratio of approximately 0.50%, and daily liquidity, positioning it as a core holding for ESG-focused portfolios in the taxable bond segment. In recent developments, GW&K expanded its ESG capabilities in 2024 through a strategic partnership with ESG data provider Sustainalytics to enhance screening methodologies; additionally, the fund acquired positions in green bonds issued by renewable energy firms following a $50 million inflow from institutional allocations in Q3 2025, reflecting heightened demand for climate-aligned fixed income amid rising interest rates.
