As further described below, the Portfolios design emphasizes long-term drivers of expected returns identified by the Advisors research, while balancing risk through broad diversification across companies and sectors. The Advisors portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs. The U.S. Large Cap Equity Portfolio is designed to purchase a broad and diverse group of readily marketable equity securities of U.S. companies that the Advisor determines to be large capitalization companies within the U.S. Universe. A companys market capitalization is the number of its shares outstanding times its price per share. The Advisor generally defines the U.S. Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the U.S. Universe it represents) of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Advisor. As of the date of this Prospectus, for purposes of the Portfolio, the Advisor considers large cap companies to be companies whose market capitalizations are generally in the highest 90% of total market capitalization within the U.S. Universe or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company within the U.S. Universe, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of eligible operating companies within the U.S. Universe. Under the Advisors market capitalization guidelines described above, based on market capitalization data as of December 31, 2025, the market capitalization of a large cap company would be $16,768 million or above. This threshold will change due to market conditions. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in equity securities of large cap U.S. companies. The Advisor generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Advisor. The Advisor may overweight certain securities, including smaller companies, lower relative price stocks, and/or higher profitability stocks within the large cap segment of the U.S. Universe. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Advisor may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Advisor uses for assessing relative price and profitability are subject to change from time to time. The Advisor may also increase or reduce the U.S. Large Cap Equity Portfolios exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a companys price momentum and short-run reversals. In addition, the Advisor seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs. The U.S. Large Cap Equity Portfolio may purchase or sell futures contracts and options on futures contracts for U.S. equity securities and indices to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Portfolio. The U.S. Large Cap Equity Portfolio may lend its portfolio securities to generate additional income. Show less
