On 11/30/06, the Fund changed to an active management strategy. Past performance through 11/29/06 represents the former passive investment strategy, and is not indicative of future results.

Institutional shares were not offered prior to 11/28/08. All performance information for time periods beginning prior to November 28 is the performance of the Investor shares. This performance has not been adjusted to reflect the lower expenses of the Institutional shares.

Annual Expense Ratio: Gross: 0.74% / Net: 0.74%. Per current prospectus. Domini has contractually agreed to waive certain fees and/or reimburse certain ordinary operating expenses in order to limit Institutional share expenses to 0.74% of its average daily net assets per annum until 11/30/18, absent an earlier modification by the Fund’s Board. See prospectus for details. The Fund's performance would have been lower had these fees not been waived.

Past performance is no guarantee of future results. The Fund’s returns quoted above represent past performance after all expenses. The returns reflect any applicable expense waivers in effect during the periods shown. Without such waivers, Fund performance would be lower. Investment return, principal value, and yield will fluctuate.  Your shares, when redeemed, may be worth more or less than their original cost. Select the Performance Tab above for more complete performance information, including returns current to the most recent month-end, which may be lower or higher than the performance data quoted. A 2.00% redemption fee applies 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 prospectus for further information.
