Shareholder Activism
The Fund also advances its social objectives by proxy voting, through continuing dialogue with corporations and by filing shareholder resolutions.

Social and Environmental Standards
To determine which securities are eligible for investment by the Fund, Domini will evaluate current and potential holdings against its social and environmental standards based on the businesses in which corporations are engaged and the quality of their relations with communities, customers, ecosystems, employees, investors, and suppliers. Domini may determine that a security is eligible for investment even if a corporation’s profile reflects a mixture of positive and negative social and environmental characteristics.
