Calvert for Institutional Investors
Regulatory XBRL files

Effective January 1, 2011, the SEC requires mutual funds to file their risk/return summaries in XBRL or interactive data format. Calvert has done that for the prospectuses that are filed effective January 31, 2011. We are also required to make the actual XBRL files available on our Web site. They are below.
