Domini Impact Investments LLC (the Adviser), the Funds adviser, seeks to identify investment opportunities for the Fund that, in the Advisers view, create positive environmental and social outcomes for people and the planet, while also seeking competitive financial returns (Impact Investing). All of the investment selections made by the Adviser are based on the evaluation of environmental and social factors, including the core business in which a company engages and/or how a company treats its key stakeholders, such as its customers, employees, suppliers, ecosystems, local, national and global communities, and/or investors (environmental and social factors). The Fund may, but is not required to, invest in companies that, in addition to being evaluated by the Adviser on environmental and social factors, also demonstrate a commitment to sustainability solutions. The Adviser will consider a company to demonstrate a commitment to sustainability solutions if the Adviser determines, based on its analysis, that the company provides, invests in or creates products or services that seek to help: accelerate the transition to a low-carbon future, contribute to the development of sustainable and resilient communities, promote a circular economy with sustainable production and consumption, provide access to clean water, support more sustainable food and agricultural systems, promote societal health and well-being, broaden financial inclusion and/or promote sustainable finance, or bridge the digital divide and/or support sustainable information and communication systems. A company that demonstrates a commitment to sustainability solutions is also evaluated on financial criteria. A security will be sold if the Adviser determines that the company is no longer eligible for investment based on the Advisers ongoing evaluation of environmental and social factors, financial criteria, and/or the company no longer demonstrates a commitment to sustainability solutions, as applicable. SSGA Funds Management, Inc. (the Subadviser), the Funds subadviser, will purchase or sell securities to implement the Advisers investment selections at a time determined appropriate by the Subadviser and in accordance with, but not necessarily in the identical amounts as provided with the Advisers investment selections.
