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. A sustainable investment strategy which incorporates environmental, social and governance criteria may result in lower or higher returns than an investment strategy that does not include such criteria.
