Investment objective & strategy

As of Feb. 27, 2026 · prospectus

Objective. The fund seeks long-term capital growth and current income by investing approximately 60% of its assets in equity securities and the remainder in bonds and other fixed-income securities.

Strategy. For the equity portion of the fund, the fund will generally invest in large capitalization companies it believes show business improvement using a proprietary multi-factor model that combines fundamental measures of a stocks value and growth potential with sustainability (environmental, social, and governance) characteristics. To measure value, the portfolio managers may use ratios of stock price-to-earnings and stock price-to-cash flow. To measure growth, the managers may use the rate of growth of a companys earnings and cash flow and changes in its earnings estimates. The model also considers price momentum. The team evaluates multiple sustainability characteristics utilizing internal data and research, as well as third party commercial data sources and scoring systems. To the extent such information is available and … For the equity portion of the fund, the fund will generally invest in large capitalization companies it believes show business improvement using a proprietary multi-factor model that combines fundamental measures of a stocks value and growth potential with sustainability (environmental, social, and governance) characteristics. To measure value, the portfolio managers may use ratios of stock price-to-earnings and stock price-to-cash flow. To measure growth, the managers may use the rate of growth of a companys earnings and cash flow and changes in its earnings estimates. The model also considers price momentum. The team evaluates multiple sustainability characteristics utilizing internal data and research, as well as third party commercial data sources and scoring systems. To the extent such information is available and relevant for a particular company, portfolio managers will consider, among others, a companys carbon emission profile, energy and water usage, or waste generation (environmental), a companys employee turnover rates, digital privacy, or worker safety (social), and a companys corporate leadership, including board chair independence and the independence of audit and compensation committees or shareholder rights such as say on pay (governance). If sustainability characteristics are unavailable or incomplete, a security may still be selected for the portfolio if the portfolio managers believe they can evaluate the security qualitatively, or if the financial metrics and/or remaining sustainability characteristics merit investment. Qualitative review of portfolio securities may include examination of registration statements and other information provided by the company as well as engagement with company management. Each security is evaluated on a sector-specific basis, and the fund seeks to hold securities with the strongest attributes in their respective sectors. Using this process, the portfolio managers attempt to build a portfolio of stocks that provides better returns without taking on significant additional risk, and maintains a stronger sustainability profile than the S&P 500 Index. For the fixed-income portion of the fund, the portfolio managers invest in a diversified portfolio of high- and medium-grade non-money market debt securities. These securities, which may be payable in U.S. or foreign currencies, may include corporate bonds and notes, government securities, bank loans, securities backed by mortgages or other assets and collateralized debt obligations (including collateralized loan obligations). Shorter-term debt securities round out the portfolio. The fund also may invest in derivative instruments such as options, futures contracts, options on futures contracts, and swap agreements (including, but not limited to, credit default swap agreements), or in mortgage- or asset-backed securities, provided that such investments are in keeping with the fund's investment objective. The fund may use foreign currency exchange contracts to shift investment exposure from one currency into another for hedging purposes.
