What is the Calvert Social Index?

Calvert, a leader in socially responsible investing, has created
the Calvert Social Index(R) as a broad-based, rigorously constructed
benchmark for measuring the performance of US-based socially
responsible companies.

How is the Calvert Social Index constructed?

Calvert starts by taking the 1,000 largest companies in the US,
represented by stocks listed on the NYSE and NASDAQ-AMEX (not
including closed-end mutual funds, ADRs, REITS and non-common shares).
Calvert's Social Research Department then analyzes each company. A
social audit is conducted in the following areas: governance and
ethics; environment; workplace; product safety and impact; community
relations; international operations and human rights; and indigenous
peoples' rights. The stocks that meet Calvert's social criteria make
up the Calvert Social Index.
