The Sub-Adviser generally uses a growth approach, looking for companies with one or more of the following characteristics: a demonstrated ability to consistently increase revenues, earnings, and cash flow; capable management; attractive business niches; and a sustainable competitive advantage. Valuation measures, such as a company's price/earnings ratio relative to the market and its own growth rate, are also considered./spanspan style="color:#000000;font-family:Arial;font-size:9.30pt;margin-left:0%;"The Portfolio typically limits holdings of high-yielding stocks, but the payment of dividends – even above-average dividends – /spanspan style="color:#000000;font-family:Arial;font-size:9.30pt;"does not disqualify a stock from consideration.

These special situations might arise when the Sub-Adviser believes a security could increase in value for a variety of reasons, including an extraordinary corporate event, a new product introduction or innovation, a favorable competitive development, or a change in management./spanspan style="color:#000000;font-family:Arial;font-size:9.30pt;margin-left:0%;"While most assets will be invested in U.S. common stocks, to a limited extent, other securities may also be purchased, /spanspan style="color:#000000;font-family:Arial;font-size:9.30pt;"including foreign (non-U.S.) stocks, futures, and forward foreign currency exchange contracts, in keeping with the Portfolio's investment objective. Any investments in futures would typically serve as an efficient means of gaining exposure to certain markets or as a cash management tool to maintain liquidity while being invested in the market. Forward foreign currency exchange contracts would primarily be used to help protect the Portfolio's foreign (non-U.S.) holdings from unfavorable changes in foreign currency exchange rates.

For certain types of investments, including, but not limited to, cash, currency positions, and particular types of derivatives, an ESG analysis may not be relevant or possible due to a lack of data. Where ESG considerations are integrated into the investment research process, the Sub-Adviser focuses on the ESG factors it considers most likely to have a material impact on the performance of the holdings in the Portfolio’s portfolio.
