Calvert Social Index Construction

The Calvert Social Index(TM) is created by taking the 1,000 largest companies in the U.S., representing stocks listed on the NYSE and NASDAQ-AMEX (not including closed-end mutual funds, ADRs, REITS, and non-common shares) and ranks them in descending order based on their market capitalization.

Calvert's Social Research Department analyzes each company in the base of 1,000 companies. A social audit is conducted in the following areas: environment, workplace issues, product safety, community relations, military weapons contracting, international operations and human rights, and respecting the rights of indigenous peoples. The stocks that meet Calvert's social criteria make up the Calvert Social Index.
