Stocks will fluctuate in response to factors that may affect a single company, industry, sector, country, region or the market as a whole and may perform worse than the market. Foreign securities are subject to additional risks such as currency fluctuations, regional economic and political conditions, differences in accounting methods, and other unique risks compared to investing in securities of U.S. issuers. Bonds are subject to risks including interest rate, credit, and inflation. The Funds’ environmental criteria limit the investments available to the Funds compared to mutual funds that do not use environmental criteria; as a result, performance could be affected.
