The Sub-Adviser is responsible for the day-to-day management of the Funds assets. For the equity portion of the Fund, the Fund will generally invest in large capitalization companies that the Sub-Adviser believes show sustainable business improvement using a proprietary multi-factor model that combines fundamental measures of a stocks value and growth potential with environmental, social, and governance (ESG) metrics. The model assigns each security a financial metrics score and an ESG score that are combined to create an overall score. Equity securities include common stock and may include preferred stock or other types of stock. To measure value, the Sub-Adviser may use ratios of stock price-to-earnings and stock price-to-cash flow. To measure growth, the Sub-Adviser 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 Sub-Adviser arrives at an ESG score by evaluating multiple metrics of each ESG characteristic environmental, social, and governance. To the extent such information is available and relevant for a particular company, the Sub-Adviser 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 an ESG score is unavailable or incomplete, a security may still be selected for the portfolio if the Sub-Adviser believes it can evaluate the security qualitatively, or if the financial metrics and/or remaining ESG data 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. Final scores for each security are evaluated on a sector-specific basis, and the Fund seeks to hold securities with the strongest scores in their respective sectors. Using this process, the Sub-Adviser attempts to build a portfolio of stocks that has sustainable competitive advantages, provides better returns without taking on significant additional risk, and maintains a stronger ESG profile than the S&P 500 Index. The Sub-Adviser evaluates the respective ESG profiles of the Funds portfolio and the S&P 500 Index by aggregating the proprietary ESG scores of the individual securities included in each and comparing the resulting totals. The market capitalization range of the S&P 500 Index was $5.28 billion to $3.34 trillion as of March 31, 2025. For the fixed-income portion of the Fund, the Sub-Adviser invests 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, collateralized debt obligations and 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. Specifically, the Fund may use credit default swaps to manage credit exposure, inflation swaps to manage inflation exposure, and Treasury futures to manage duration. The Fund may use foreign currency exchange contracts to shift investment exposure from one currency into another for hedging purposes. Show less
