The portfolio managers look for stocks of medium capitalization companies they believe will increase in value over time, using proprietary fundamental research. The initial research process begins by analyzing the United Nations Sustainable Development Goals (SDG) to identify companies that generate, or could generate, social and environmental impact alongside a financial return. SDGs are a collection of global goals set by the United Nations General Assembly-examples include: affordable and clean energy; decent work and economic growth; industry, innovation, and infrastructure; and responsible consumption and production. The portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. They generate an impact thesis-an assessment of current or projected SDG alignment in combination with a fundamental growth profile-for each security. The portfolio managers may use commercial third party mapping tools, frameworks provided by sustainable investing platforms, or internal research, which may include engaging with a company's leadership, to create each security's SDG impact thesis. To decide whether a security aligns with an SDG, the portfolio managers place the most emphasis on the impact created by the product or service its issuing company produces. This helps the portfolio managers to avoid impact washing-investing in a company that is not truly advancing any of the SDGs, but is attempting to present itself as though it is (i.e., a company with a poor environmental track record touting that it will convert all of its delivery vehicles to clean burning natural gas, or a company with documented human rights abuses publicizing the diversity of its board of directors). While some securities in the fund's portfolio may align with more than one SDG, to be eligible for selection by the portfolio managers, it is only necessary that a security aligns with one SDG. The fund does not prioritize any SDG over another, and so long as each security maps to at least one SDG, there is no minimum number of SDGs that must be represented in the portfolio.
