The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for Class A sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Investor or Class A shares of each Domini Fund, except the Domini Social Bond Fund. More information about these and other discounts is available from your financial professional or in the Fund’s prospectus on page A-15 under the heading “How Sales Charges Are Calculated for Class A Shares” and in the Fund’s Statement of Additional Information (“SAI”) on page 32 under the heading “Additional Information Regarding Class A Sales Charges.” Shareholder fees (paid directly from your investment) Annual Fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) Portfolio turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 94% of the average value of its portfolio. Example This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year, and that the Fund’s operating expenses (reflecting applicable contractual fee waivers and expense reimbursement arrangements) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be as follows: Share classes (whether or not shares are redeemed) Share classes (whether or not shares are redeemed) Principal investment strategies: Under normal circumstances, the Fund primarily invests in the equity securities of mid- and large-capitalization U.S. companies. Under normal circumstances, at least 80% of the Fund’s assets will be invested in equity securities and related investments with similar economic characteristics. The Fund may also invest in companies organized or traded outside the U.S. (or in equivalent shares such as ADRs). Domini evaluates the Fund’s potential investments against its social and environmental standards based on the businesses in which they engage, as well as on the quality of their relations with key stakeholders, including communities, customers, ecosystems, employees, investors, and suppliers. For additional information about the standards Domini uses to evaluate potential investments and the securities held by the Fund, and certain limitations on investments, please see “Socially Responsible Investing.” Domini reserves the right to alter its social and environmental standards or the application of those standards, or to add new standards, at any time without shareholder approval. Principal risks: Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly in the short and long term. You may lose all or part of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund. <ul type="square"><li style="margin-left:--10px"><blockquote>Foreign Investing risk. Investments in foreign regions or in securities of issuers with significant exposure to foreign markets 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; natural disasters; and the degree of government oversight and supervision.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Information risk. There is a risk that information used by the adviser to evaluate the social and environmental performance of issuers, industries, markets, sectors, and regions may not be readily available, complete, or accurate, which could negatively impact the adviser’s ability to apply its social and environmental standards, which may negatively impact Fund performance. This may also lead the Fund to avoid investment in certain issuers, industries, markets, sectors, or regions.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Market risk. The market prices of Fund securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the markets, or adverse investor sentiment. When market prices fall, the value of your investment will go down. The financial crisis that began in 2008 caused a significant decline in the value and liquidity of many securities of issuers worldwide. Some government and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure their debts, and many other issuers have faced difficulties in obtaining credit. These market conditions may continue to worsen or spread, including in the U.S., Europe, and beyond. Further defaults or restructurings of their debt by governments and others could have additional adverse effects on economies, financial markets, and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund’s investments. Legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Mid-to Large-Cap Companies risk. The market prices of companies at different capitalization levels may go up or down due to general market conditions and cycles. The value of your investment will be affected by the Fund’s exposure to mid- and large-cap companies.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Sector Concentration risk. The Fund may hold a large percentage of securities in a single sector (e.g., financials). If the Fund holds a large percentage of securities in a single sector, its performance will be tied closely to and affected by the performance of that sector.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Socially Responsible Investing risk. The application of the adviser’s social and environmental standards will affect the Fund’s 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.</blockquote></li></ul><ul type="square"><li style="margin-left:--10px"><blockquote>Style risk. The value of your investment may decrease if the subadviser’s quantitative investment approach does not respond well to current market conditions or its judgment regarding the quality, value, or market trends affecting a particular security, industry, sector or region is incorrect. The submanager’s quantitative model relies upon a complex software system, and failure of the system to function or the presence of software errors could have an adverse impact on the value of Fund performance.</blockquote></li></ul>These and other risks are discussed in more detail later in this prospectus or in the SAI. Please note that there are many other factors that could adversely affect your investment and that could prevent the Fund from achieving its goals. Investment results: The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year for Investor shares and by showing how the Fund’s average annual total returns for 1, 5, and 10 years compare with those of a broad measure of market performance, the Standard and Poor’s 500 Index (S&P 500), an unmanaged index of common stocks. The returns for each class of the Fund will differ from Investor shares because of the different expenses applicable to those share classes. The returns presented in the table for periods prior to the inception of the Class A, Institutional, and Class R shares reflect the performance of the Investor shares. Class A shares and Institutional shares commenced operations on November 28, 2008. Class R shares commenced operations on November 28, 2003. These returns have not been adjusted to take into account the lower expenses applicable to Class A, Institutional, and Class R shares, but for Class A shares, the returns in the table reflect a deduction for the maximum sales charge.

Shareholder fees (paid directly from your investment) Annual Fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) Portfolio turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 126% of the average value of its portfolio. Example This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year, and that the Fund’s operating expenses (reflecting applicable contractual fee waivers and expense reimbursement arrangements) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be as follows: Principal investment strategies: Under normal circumstances, the Fund invests at least 85% of its assets in investment-grade securities and maintains a dollar-weighted average effective maturity of between two and ten years. Under normal circumstances, at least 80% of the Fund’s assets will be invested in bonds, including government and corporate bonds, mortgage-backed and asset-backed securities, and U.S. dollar denominated bonds issued by non-U.S. entities. Some of these instruments may not be insured and may earn below-market rates of return. Some investments may be unrated, lower-rated, or illiquid securities. Domini evaluates the Fund’s potential corporate debt instruments against its social and environmental standards based on the businesses in which they engage, as well as on the quality of their relations with key stakeholders, including communities, customers, ecosystems, employees, investors, and suppliers. For noncorporate issuers, Domini seeks to identify investments with a positive impact on communities.

Principal risks: Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly in the short and long term. You may lose all or part of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund. <ul type="square"><li style="margin-left:30px">Credit risk. Fixed-income securities are subject to credit risk. Credit risk is the possibility that an issuer will fail to make timely payments of interest or principal, or go bankrupt. The lower the ratings of such debt securities, the greater their risks. In addition, lower-rated securities have higher risk characteristics, and changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations. Below investment grade securities (sometimes referred to as “junk bonds”) involve greater risk of default or downgrade and are more volatile than investment grade securities. Below investment grade securities may also be less liquid than higher-quality securities. </li></ul><ul type="square"><li style="margin-left:30px"> Government-Sponsored Entities risk. The Fund’s investments in securities issued by government-sponsored entities such as Fannie Mae, Freddie Mac, and the Federal Home Loan Bank are not guaranteed or insured by the U.S. government and may decline in value.</li></ul><ul type="square"><li style="margin-left:30px"> Information risk. There is a risk that information used by the adviser to evaluate the social and environmental performance of issuers, industries, markets, and sectors, may not be readily available, complete, or accurate, which could negatively impact the adviser’s ability to apply its social and environmental standards which may negatively impact Fund performance. This may also lead the Fund to avoid investment in certain issuers, industries, markets, or sectors. </li></ul><ul type="square"><li style="margin-left:30px"> Interest Rate risk. The value of your investment will fluctuate with interest rates. If interest rates rise, the price of a fixed-income security declines and could reduce the value of the Fund’s share price. A rise in rates tends to have a greater impact on securities with longer maturities or higher durations.</li></ul><ul type="square"><li style="margin-left:30px"> Liquidity risk. Some securities held by the Fund may be difficult to sell, or may be illiquid, particularly during times of market turmoil. Illiquid securities also may be difficult to value. Due to limitations on investments in illiquid securities the Fund may be unable to achieve its desired level of exposure to certain sectors. If the Fund is forced to sell an illiquid asset to meet redemption request or other cash needs, the Fund may be forced to sell such securities at a loss.</li></ul><ul type="square"><li style="margin-left:30px"> Market risk. The market prices of Fund securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the markets, or adverse investor sentiment. When market prices fall, the value of your investment will go down. The financial crisis that began in 2008 caused a significant decline in the value and liquidity of many securities of issuers worldwide. Some government and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure their debts, and many other issuers have faced difficulties in obtaining credit. These market conditions may continue to worsen or spread, including in the U.S., Europe, and beyond. Further defaults or restructurings of their debt by governments and others could have additional adverse effects on economies, financial markets, and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund’s investments. Legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time. </li></ul><ul type="square"><li style="margin-left:30px"> Prepayment and Extension risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund also may lose any premium it paid on the security. If interest rates rise, repayments of fixed-income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.</li></ul><ul type="square"><li style="margin-left:30px"> Socially Responsible Investing risk. The application of the adviser’s social and environmental standards will affect the Fund’s exposure to certain issuers, industries, and sectors and may impact the relative financial performance of the Fund — positively or negatively — depending on whether such investments are in or out of favor.</li></ul>These and other risks are discussed in more detail later in this prospectus or in the SAI.

The Fund’s investments will normally be tied economically to at least 10 different countries other than the U.S. Under normal circumstances, at least 80% of the Fund’s assets will be invested in equity securities and related investments with similar economic characteristics. The Fund will primarily invest in companies tied economically to developed market countries throughout the world (or equivalent shares such as ADRs or other securities representing underlying shares of foreign companies) but may invest up to 10% of its assets in companies tied economically to emerging-market countries. Domini evaluates the Fund’s potential investments against its social and environmental standards based on the businesses in which they engage, as well as on the quality of their relations with key stakeholders, including communities, customers, ecosystems, employees, investors, and suppliers. For additional information about the standards Domini uses to evaluate potential investments and the securities held by the Fund, and certain limitations on investments, please see “Socially Responsible Investing.” Domini reserves the right to alter its social and environmental standards or the application of those standards, or to add new standards, at any time without shareholder approval. Principal risks: Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly in the short and long term. You may lose all or part of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund. <ul type="square"><li style="margin-left:30px">Country risk. The Fund expects to diversify its investments among issuers with significant exposure to various countries throughout the world but it may hold a large number of securities with exposure to a single country. Such exposure would increase the risk that economic, political, and social conditions in a country will have a significant impact on Fund performance.</li></ul><ul type="square"><li style="margin-left:30px">Currency risk. Fluctuations between the U.S. dollar and foreign currency exchange rates could negatively affect the value of the Fund’s investments. The Fund will benefit when foreign currencies strengthen against the dollar and will be hurt when foreign currencies weaken against the dollar. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of U.S. and foreign governments or central banks, the imposition of currency controls or restrictions and speculation.</li></ul><ul type="square"><li style="margin-left:30px">Foreign Investing and Emerging Markets risk. 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, confiscatory taxation, and political or financial instability; regulatory differences, such as accounting, auditing, and financial reporting standards and practices; natural disasters; and the degree of government oversight and supervision. These risks may be heightened in connection with investments in emerging-market countries.</li></ul><ul type="square"><li style="margin-left:30px">Information risk. There is a risk that information used by the adviser to evaluate the social and environmental performance of issuers, industries, markets, sectors, and regions may not be readily available, complete, or accurate, which could negatively impact the adviser’s ability to apply its social and environmental standards, which may negatively impact Fund performance. This may lead the Fund to avoid investment in certain issuers, industries, markets, sectors, or regions.</li></ul><ul type="square"><li style="margin-left:30px">Market risk. The market prices of Fund securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, inflation, changes in interest rates, lack of liquidity in the markets, or adverse investor sentiment. When market prices fall, the value of your investment will go down. The financial crisis that began in 2008 caused a significant decline in the value and liquidity of many securities of issuers worldwide. Some government and non-governmental issuers (notably in Europe) have defaulted on, or been forced to restructure their debts, and many other issuers have faced difficulties in obtaining credit. These market conditions may continue to worsen or spread, including in the U.S., Europe, and beyond. Further defaults or restructurings of their debt by governments and others could have additional adverse effects on economies, financial markets, and asset valuations around the world. Whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, these events could negatively affect the value and liquidity of the Fund’s investments. Legislation recently enacted in the U.S. calls for changes in many aspects of financial regulation. The impact of the legislation on the markets, and the practical implications for market participants, may not be fully known for some time.</li></ul><ul type="square"><li style="margin-left:30px">Mid-to Large-Cap Companies risk. The market prices of companies at different capitalization levels may go up or down due to general market conditions and cycles. The value of your investment will be affected by the Fund’s exposure to mid- and large-cap companies.</li></ul><ul type="square"><li style="margin-left:30px">Sector Concentration risk. The Fund may hold a large percentage of securities in a single sector (e.g., financials). If the Fund holds a large percentage of securities in a single sector, its performance will be tied closely to and affected by the performance of that sector.</li></ul><ul type="square"><li style="margin-left:30px">Socially Responsible Investing risk. The application of the adviser’s social and environmental standards will affect the Fund’s 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.</li></ul><ul type="square"><li style="margin-left:30px"> Style risk. The value of your investment may decrease if the subadviser’s quantitative investment approach does not respond well to current market conditions or its judgment regarding the quality, value, or market trends affecting a particular security, industry, sector, or region is incorrect. The submanager’s quantitative model relies upon a complex software system, and failure of the system to function or the presence of software errors could have an adverse impact on the value of Fund performance.</li></ul>These and other risks are discussed in more detail later in this prospectus or in the SAI. Please note that there are many other factors that could adversely affect your investment and that could prevent the Fund from achieving its goals. Investment results: The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year for Investor shares and by showing how the Fund’s average annual total returns for 1, 5, and 10 years, as applicable, compare with those of a broad measure of market performance, the Morgan Stanley Capital International Europe, Australasia, and Far East Index (MSCI EAFE), a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. The returns for each class of the Fund will differ from Investor shares because of the different expenses applicable to those share classes. The Class A returns presented in the table for periods prior to the November 28, 2008, inception of the Class A shares reflect the performance of the Investor shares. Such returns have not been adjusted to take into account the lower expenses applicable to Class A shares, but in the table have been adjusted to reflect a deduction for the maximum sales charge. Because Institutional shares were not offered prior to November 30, 2012, no performance information is shown for such shares.
