- Thornburg Better World International Fund Class I (TBWIX) is an actively managed mutual fund that seeks long-term capital appreciation by investing primarily in a portfolio of foreign equity securities and depositary receipts of non-U.S. companies demonstrating strong potential for sustainable financial growth combined with positive environmental and social impact. The fund targets large-growth stocks in the foreign large blend category, focusing on issuers that integrate environmental, social, and governance (ESG) criteria while benchmarking performance against the MSCI ACWI ex-U.S. Index; its portfolio typically comprises 60-80 holdings with sector exposures including information technology, financials, industrials, consumer discretionary, and healthcare. Managed by portfolio managers including Lei Wang, Joe Salmond, and Brian Burrell, the Class I shares feature a net expense ratio of 0.90%, a minimum initial investment of $2.5 million, and annual turnover around 141%, serving institutional investors and financial advisors seeking ESG-aligned international equity exposure.
Launched on September 30, 2015, as part of Thornburg Investment Trust, the fund operates from the headquarters of its adviser, Thornburg Investment Management, a privately held global asset manager founded in 1982 and based in Santa Fe, New Mexico, with additional offices in London and Hong Kong. Thornburg Investment Management oversees approximately $45 billion in client assets across mutual funds, ETFs, closed-end funds, separate accounts, and UCITS funds targeting institutions, high-net-worth individuals, and advisors worldwide, with geographic focus spanning developed and emerging markets outside the U.S..
In recent developments, Thornburg Investment Management launched its first active ETFs in January 2025, including the Thornburg International Growth ETF, expanding access to high-conviction equity strategies. The firm formed a private credit joint venture with Bow River Capital in July 2025 to offer flexible solutions for lower- and middle-market businesses, leveraging complementary expertise in fixed income and alternatives. Additional strategic enhancements in 2025 included reclassifying several UCITS funds, such as the Thornburg International Equity Fund, to Article 8 under EU SFDR regulations; reducing management fees on multiple funds; renaming and repositioning the Thornburg Investment Income Builder Fund (UCITS) as Thornburg Equity Income Builder Fund; opening a London office; and partnering with Capital Strategies Partners in October 2025 to bolster distribution in Italy and the Middle East. These initiatives reflect Thornburg's commitment to ESG integration, cost efficiency, and global expansion amid $560 million in net assets for TBWIX as of late 2025.
