Strategy. Investments We invest mainly in common stocks of U.S. companies of any size, with a focus on companies that we believe exhibit a commitment to financially material sustainable business practices. We may also invest in non-U.S. companies. In evaluating investments for the fund, we view financially material sustainable business practices as business practices that we believe are reasonably likely to impact the financial condition or operating performance of a company and that relate to environmental, social, or corporate governance issues. We identify relevant ESG issues on a sector-specific basis using an internally developed materiality map, which is informed by the industry-specific financial materiality framework of the Sustainability Accounting Standards Board (SASB, now incorporated in the International Financial Reporting Standards Foundation). … Show more… Investments We invest mainly in common stocks of U.S. companies of any size, with a focus on companies that we believe exhibit a commitment to financially material sustainable business practices. We may also invest in non-U.S. companies. In evaluating investments for the fund, we view financially material sustainable business practices as business practices that we believe are reasonably likely to impact the financial condition or operating performance of a company and that relate to environmental, social, or corporate governance issues. We identify relevant ESG issues on a sector-specific basis using an internally developed materiality map, which is informed by the industry-specific financial materiality framework of the Sustainability Accounting Standards Board (SASB, now incorporated in the International Financial Reporting Standards Foundation). As part of this analysis, we may utilize metrics and information such as emissions data, carbon intensity, sources of energy used for operations, water use and re-use, water generation, waste diversion from landfill, employee safety and diversity data, supplier audits, product safety, board composition, and incentive compensation structures. Stocks of companies that exhibit a commitment to financially material sustainable business practices are typically, but not always, considered to be growth stocks. Growth stocks are stocks of companies whose revenues, earnings, or cash flows are expected to grow faster than those of similar firms, and whose business growth and other characteristics may lead to an increase in stock price. We may consider, among other factors, a companys sustainable business practices (as described above), valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell investments. We may also invest in non-U.S. companies. Under normal circumstances, the fund invests at least 80% of the value of its net assets in securities that meet our sustainability criteria. These criteria are based on a proprietary materiality map that is informed by the industry-specific financial materiality framework of SASB. In applying these criteria, we will assign each company a proprietary ESG rating ranging from 1 to 4 (1 indicating the highest (best) ESG rating and 4 indicating the lowest (worst) ESG rating). In order to meet our sustainability criteria for purposes of this investment policy, a company must be rated 2 or 1 by us. This policy is non-fundamental and may be changed only after 60 days notice to shareholders. In selecting each investment, we focus on companies that have a demonstrated commitment to sustainable business practices in areas that are relevant and material to their long-term financial returns and risk profiles. We believe that companies that have exhibited such a commitment also often demonstrate potential for strong financial growth. This commitment may be reflected through ESG policies, practices, or outcomes. The funds approach to sustainable investing incorporates fundamental research together with consideration of ESG factors. Environmental factors include, for example, a companys carbon intensity and use of resources like water or minerals. Sustainability measures in this area might include plans to reduce waste, increase recycling, raise the proportion of energy supply from renewable sources, or improve product design to be less resource intensive. Social factors include, for example, labor practices and supply chain management. Sustainability measures in this area might include programs to improve employee well-being, commitment to workplace equality and diversity, or improved stewardship of supplier relationships and working conditions. Corporate governance factors include, for example, board composition and executive compensation. Sustainability measures in this area might include improvements in board independence or diversity, or alignment of management incentives with the companys strategic sustainability objectives. Our integrated approach combines analysis of the growing body of ESG data and deep fundamental analysis and looks for companies that demonstrate leadership, beyond compliance, on relevant sustainability issues. The characteristics that we may use when considering sustainability leadership include: (1) Material. Focused on strategic, business-relevant issues. (2) Proactive. Actions that go beyond basic requirements to create potential business benefit. (3) Transparent. Reporting that is relevant, timely, and candid. (4) Effective. Creating benefits both within the firm and beyond its corporate borders. Show less
