What is the Calvert Social Index?

Calvert, a leader in sustainable and responsible investing, has created the
Calvert Social Index, a broad-based, rigorously constructed benchmark for
measuring the performance of US-based sustainable and responsible companies.

How is the Calvert Social Index constructed?

Calvert starts by taking the 1,000 largest companies in the US, based on total
market capitalization, included in the Dow Jones Total Market Index (the “Dow
Jones TMI”). The Dow Jones TMI represents the top 95% of U.S. companies based
on float-adjusted market capitalization, excluding the very smallest and
least-liquid stocks. Calvert's Sustainability Research Department then
analyzes each company. A sustainability 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 the Index’s sustainable and
responsible criteria make up the Calvert Social Index.
