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. See the Performance tables 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.

An investment in the Domini Impact International Equity Fund is not a bank deposit and is not insured. The Fund is subject to certain risks including loss of principal, foreign investing and emerging markets, geographic focus, country, currency, impact investing, portfolio management, and quantitative investment approach risks. Investing internationally involves special risks, such as currency fluctuations, social and economic instability, differing securities regulations and accounting standards, limited public information, possible changes in taxation, and periods of illiquidity. These risks may be heightened in connection with investments in emerging market countries. You may lose money. See the prospectus for more information on risk.

The Adviser’s evaluation of environmental and social factors in its investment selections, as well as its evaluation of a company’s commitment to sustainability solutions, and the timing and amount of the Subadviser’s implementation of the Adviser’s investment selections will affect the Funds’ exposure to certain issuers, industries, sectors, regions, and countries and may impact the relative financial performance of the Fund – positively or negatively – depending on whether such investments are in or out of favor. The Fund may forego some investment opportunities, including investments in certain market sectors that are available to funds that do not consider environmental and social factors and sustainability solutions in their investment selections.

The performance above does not reflect the deduction of fees and taxes that a shareholder would pay on Fund 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.
