SUSTAINABLE EQUITY FUND INVESTOR CLASS (AFDIX) Exchange: NMFQS

The fund will generally invest in larger-sized companies using a quantitative model that combines fundamental measures of a stock’s value and growth potential. To measure value, the managers may use ratios of stock price-to-earnings and stock price-to-cash flow, among others. To measure growth, the managers may use the rate of growth of a company’s earnings and cash flow and changes in its earnings estimates, as well as other factors. The model also considers price momentum. The portfolio managers also take environmental, social and governance ("ESG") factors into account in making investment decisions.  The portfolio managers attempt to build a portfolio of stocks that provides better returns than, and a dividend yield comparable to, the S&P 500® Index, without taking on significant additional risk.Under normal market conditions, the fund will invest at least 80% of its net assets in equity securities.Although the portfolio managers intend to invest the fund’s assets primarily in U.S. securities, the fund may invest in securities of foreign companies when these securities meet the portfolio managers’ standards of selection.The fund may write covered calls on a portion of the fund’s holdings in common stock when the portfolio managers believe call premiums are attractive relative to the price of the underlying security.When determining whether to sell a security, the portfolio managers consider among other things, a security’s price, whether a security’s risk parameters outweigh its return opportunities, general market conditions, whether the security meets their ESG criteria, and any other factor deemed relevant by the portfolio managers.The fund is not permitted to invest in securities issued by companies assigned the Global Industry Classification Standard (GICS) or the Bloomberg Industry Classification Standard (BICS) for the tobacco industry.
