For these purposes, equity securities include equity securities of any type, including common stocks; preferred securities; warrants to purchase common stocks and preferred securities; convertible debt securities that are either in the money or immediately convertible into common stocks or preferred securities; common and preferred securities issued by master limited partnerships and real estate investment trusts; depositary receipts; and other securities with equity characteristics. The Fund attempts to achieve the return of the U.S. stock market as represented by its benchmark, the S&P 500 Index, while taking into consideration certain ESG criteria, which include criteria relating to carbon intensity and fossil fuel reserves. See Additional information about the Funds benchmark index in the non-summary portion of the Prospectus for more information about the Funds benchmark. For purposes of the 80% investment policy, large-cap securities are equity securities that have a market capitalization within the range of companies included in the S&P 500 Index on the last business day of the month in which its most recent rebalancing was completed (as adjusted by changes to the index between rebalancings) and assets means net assets, plus the amount of any borrowings for investment purposes. New Third and Fourth Paragraphs- The ESG evaluation process is conducted on an industry-specific basis and involves the identification of key performance indicators, which are given more or less relative weight compared to the broader range of potential assessment categories. When ESG concerns exist, the evaluation process gives careful consideration to how companies address the risks and opportunities they face in the context of their sector or industry and relative to their peers. The Fund will not generally invest in companies significantly involved in certain business activities, including but not limited to the production of alcohol, tobacco, military weapons, firearms, thermal coal, adult entertainment, arctic oil and gas, oil sands extraction, for-profit prisons and gambling products and services. In addition to the overall ESG performance evaluation, the Fund favors companies that (1) demonstrate leadership in managing and mitigating their current carbon intensity and (2) do not have evidence of fossil fuel reserves ownership, regardless of industry. The determination of leadership criteria takes into consideration company carbon intensity in relative terms (e.g., tons of carbon emitted per unit of economic output such as sales). Reserves are fossil fuel deposits that have not yet been extracted. Evidence of fossil fuel reserves ownership includes company disclosure and statements regarding ownership. Show less
