Investment Strategy
The Fund invests in a portfolio of primarily investment-grade fixed-income securities, including U.S. Government agency bonds, corporate debt, and mortgage- and other asset-backed securities. The Fund maintains an effective duration within two years (plus or minus) of the portfolio duration of the securities comprising the Bloomberg U.S. Aggregate Bond Index. It is managed through a two-step process designed to capitalize on the strengths of Domini Impact Investments and Wellington Management.
Guided by our Impact Investment Standards, Domini sets environmental and social guidelines and objectives for each asset class and creates an approved list of securities based on our in-depth environmental and social research and analysis. Wellington constructs and manages a portfolio of Domini-approved securities using proprietary analytical tools.
The Fund may change any of the policies described above at any time.

* Average annual total returns.
Returns for periods less than one year are not annualized.
The Fund’s current investment strategy and Subadviser services commenced on January 7, 2015. Performance information for periods beginning prior to January 7, 2015 reflects the investment strategies employed during those periods.
Annual Expense Ratio1 – Gross: 1.14% / Net: 0.87%. Per current prospectus.
1. The Fund’s Adviser has contractually agreed to waive certain fees and/or reimburse certain ordinary operating expenses (excluding brokerage fees and commissions, interest, taxes, and other extraordinary expenses) in order to limit Investor share expenses to 0.87% through November 30, 2026, absent an earlier modification by the Fund’s Board. There can be no assurance that the Adviser will extend the expense limitations beyond such time. While in effect, the arrangement may be terminated for a class only by agreement of the Adviser and the Fund’s Board of Trustees.
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. 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. See the prospectus for further information.
An investment in the Domini Impact Bond Fund is not a bank deposit and is not insured. The Fund is subject to certain risks, including the loss of principal, impact investing, portfolio management, style, information, market, interest rate, and credit risks. 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.
Although the Domini Impact Bond Fund Investor shares are no-load, certain fees and expenses apply to a continued investment and are described in the prospectus.
The Bloomberg U.S. Aggregate (BUSA) Bond Index is an index representing securities that are U.S. domestic, taxable, and dollar denominated and covering the U.S. investment-grade fixed-rate bond market, with index components for government and corporate securities and asset-backed securities.
