Domini Social Equity Fund Ranks In Top 10% Of Peer Group For One- And Three-Year Periods Ended March 31, 2011

Domini Social Investments announced today that the Domini Social Equity Fund (Nasdaq: DSEFX) ranked in the top 10% of its peer group for the 1-year and 3-year periods ended March 31, 2011.

"Our fund shareholders appreciate the fact that we work on their behalf to bring universal human dignity to those who lack it and ecological sustainability to our planet," said Amy Domini, Founder and CEO of Domini Social Investments. "We are proud to contribute to investors' triple bottom line: people, the planet, and profit."

Domini credited the Fund's strong performance during these time periods to its innovative partnership with Wellington Management Company, subadviser to the Fund since November 30, 2006. The Fund’s unique approach, designed to capitalize on each firm’s strengths, has delivered industry-leading financial performance and high social and environmental impact.

Domini is responsible for establishing the Fund’s investable universe through its proprietary social and environmental analysis. Domini utilizes more than 600 key performance indicators to implement its comprehensive Global Investment Standards.

Domini’s research framework is both broad and in-depth, focusing on the key sustainability challenges and opportunities faced by each company, within its industry context. Wellington Management then applies its quantitative modeling techniques to construct a portfolio of Domini-approved stocks. Domini then engages with portfolio holdings through proxy voting and more direct forms of shareholder activism.

The Domini Social Equity Fund was founded in 1991 by Amy Domini, widely recognized as the leading voice for socially responsible investing. Her most recent book has been translated into Japanese, Korean, and Chinese, a tribute to her pioneering work to bring finance into the business of building a better world for our children.

Past performance is no guarantee of future results. The Fund's returns quoted above represent past performance after all expenses. Investment return, principal value, and yield will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. For performance information current to the most recent quarter and month-end, visit our website or call 1-800-582-6757. Each fund charges a 2.00% redemption fee on sales or exchanges of shares made less than 30 days after the settlement of purchase or acquisition through exchange, with certain exceptions. See the Fund's current prospectus for further information.

For the period reported in its current prospectus, during which net operating expenses were capped by the Fund's Manager, the Fund's gross annual operating expenses totaled 1.29% of net assets. Until November 30, 2011, the Fund's Manager has contractually agreed to waive certain fees and/or reimburse certain expenses, including management fees, so that expenses paid by the Fund will not exceed, on a per annum basis, 1.25% of its average daily net assets representing Investor shares.

The performance information quoted above does not reflect the deduction of taxes that a shareholder would pay on distributions or the redemption of Fund shares. Total return is based on the Fund's net asset values and assumes all dividends and capital gains were reinvested. An investment in the Fund is subject to market risks and is not insured. You may lose money. Certain fees payable by the Fund were waived during the period, and the Fund's average annual total returns would have been lower had these not been waived.
