"'Make money make a difference.' That's the simple message at Domini," said Amy Domini, Founder and CEO of Domini Social Investments.

"We know our shareholders and they don't compromise their values, nor do they compromise their stewardship of assets. We're proud to work with them as they meet both goals."

The Fund has a low investment minimum of $2,500 for nonretirement accounts and $1,500 for IRAs, or if opened with an Automatic Investment Plan.

The Fund is the result of a unique partnership between Domini Social Investments and Wellington Management Company that is designed to capitalize on each firm's strength, with the goal of delivering both strong 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 engages with portfolio holdings through proxy voting and more direct forms of shareholder activism.

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 [4] 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 1.94% 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, 1.60% 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.

Investments in foreign regions may be more volatile and less liquid than U.S. investments due to adverse political, social, and economic developments, such as nationalization or expropriation of assets, imposition of currency controls or restrictions, confiscatory taxation, and political or financial instability; regulatory differences, such as accounting, auditing, and financial reporting standards and practices; and the degree of government oversight and supervision. These risks may be heightened in connection with investments in emerging-market countries.

You should consider the Domini Funds' investment objectives, risks, charges, and expenses carefully before investing.

Please read the prospectus carefully before investing or sending money.
