On January 7, 2015, Wellington Management Company LLP replaced Seix Investment Advisers as the subadvisor of the Domini Social Bond Fund.

Institutional shares were not offered prior to 11/30/2011. All performance information for time periods beginning prior to 11/30/2011 is the performance of the Investor shares, which has not been adjusted to reflect the lower expenses of the Institutional shares.

Annual Expense Ratio: Gross: 0.96% / Net: 0.56%. 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 0.57% 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.

For the period reported in its current prospectus, the Fund’s annual operating expenses totaled: Net: 0.87% / Gross: 1.10% (Investor), Net: 0.57% / Gross: 0.96% (Institutional). The Fund’s adviser has contractually agreed to waive certain fees and/or reimburse certain ordinary operating expenses in order to limit Investor and Institutional share expenses to 0.87% and 0.57%, respectively, of the average daily net assets per annum of each class. The agreement expires on November 30, 2018 absent an earlier modification by the Fund’s Board.

The 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. Certain fees and expenses also apply to a continued investment in the Fund and are described in the prospectus. See the Fund’s current prospectus for further information.

Total return for the Fund is based on the Fund’s net asset values and assumes all dividends and capital gains were reinvested. The returns above do not reflect the deduction of fees and taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

During periods of rising interest rates, bond funds can lose value. Some of the Fund’s community development investments may be unrated and may carry greater credit risks than the Fund’s other holdings. The Fund currently holds a large percentage of its portfolio in mortgage-backed securities. During periods of falling interest rates, mortgage-backed securities may prepay the principal due, which may lower the Fund’s return by causing it to reinvest at lower interest rates.

Investments in derivatives can be volatile. Potential risks include currency risk, leverage risk (the risk that small market movements may result in large changes in the value of an investment), liquidity risk, index risk, pricing risk, and counterparty risk (the risk that the counterparty may be unwilling or unable to honor its obligations). TBA (To Be Announced) securities involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation, which can adversely affect the Fund’s results.

The Fund may hold a substantial portion of its assets in the direct obligations of U.S. government agencies and government-sponsored entities such as Fannie Mae (formally known as the Federal National Mortgage Association), Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation), the Federal Farm Credit Banks Funding Corporation, or the Government National Mortgage Association (“Ginne Mae”). Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and some of its agencies, such as securities issued by the Ginne Mae, this guarantee does not apply to losses resulting from declines in the market value of these securities. Some of the U.S. government securities that the Domini Funds may hold are not guaranteed or backed by the full faith and credit of the U.S. government, and no assurance can be given that the U.S. government will provide financial support and sponsorship to Fannie Mae, Freddie Mac, or other government-sponsored enterprises in the future. The reduction or withdrawal of historical financial market support activities by the U.S. Government and Federal Reserve, or other governments/central banks could negatively impact financial markets generally, and increase market, liquidity and interest rate risks which could adversely affect the Fund’s returns.
