Under normal circumstances, the fund invests at least 80% of its assets in equity securities of U.S. Sustainable Companies. It may invest up to 20% of its assets in securities of non-U.S. companies, including those in emerging markets. Although the fund is classified as "diversified" under the Investment Company Act of 1940, as amended, it may invest in a smaller number of issuers than other, more diversified, investment portfolios.
