      Prospectus dated November 27, 2009, regarding the
              Domini Social Equity Fund(R)
                   Institutional Shares

Effective on May 21, 2010, the eligibility requirements applicable to the
Institutional Shares of the Domini Social Equity Fund set forth on page A-7
of the Prospectus have been modified to establish a $2 million minimum initial
investment for all Institutional Share accounts, including defined contribution
plan accounts. Defined contribution plan accounts continue to qualify for
Institutional Share investment at the sponsor level and cannot be aggregated
with defined contribution plans of unaffiliated sponsors to meet the $2 million
minimum initial investment amount. Omnibus or other accounts for which Domini
provides recordkeeping and/or other services or for which the Fund is required
to pay any type of administrative payment per participant account are not
eligible for the Institutional Shares.
