To achieve the U.S. Sustainability Targeted Value Portfolio’s investment objective, the Advisor implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Portfolio’s design emphasizes long-term drivers of expected returns identified by the Advisor’s research, while balancing risk through broad diversification across companies and sectors.

The Advisor’s 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. Sustainability Targeted Value Portfolio is designed to purchase a broad and diverse group of the readily marketable securities of U.S. small and mid-cap companies that the Advisor determines to be value stocks with higher profitability, while adjusting the composition of the Portfolio based on sustainability impact considerations. A company’s market capitalization is the number of its shares outstanding times its price per share. Under a market capitalization weighted approach, companies with higher market capitalizations generally represent a larger proportion of the Portfolio than companies with relatively lower market capitalizations. The representation in the Portfolio of an eligible company as compared to its representation in the U.S. small and mid-cap markets may be impacted by the Portfolio’s sustainability impact considerations. The Portfolio may emphasize certain stocks, including smaller capitalization companies, lower relative price stocks, and/or higher profitability stocks as compared to their representation in the small-and mid-cap value segment of the U.S. market. 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.

As a non-fundamental policy, under normal circumstances, the U.S. Sustainability Targeted Value Portfolio will invest at least 80% of its net assets in securities of U.S. companies.

The Advisor will consider for purchase by the U.S. Sustainability Targeted Value Portfolio securities of companies whose market capitalizations are generally smaller than the 500th largest eligible company within the U.S. Universe. 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 securities exchanges in the United States that are deemed appropriate by the Advisor. As of December 31, 2023, companies smaller than the 500th largest U.S. company fall in the lowest 13% of total U.S. market capitalization. Total market capitalization is based on the market capitalization of eligible operating companies within the U.S. Universe. Based on market capitalization data as of December 31, 2023, the market capitalization of a company smaller than the 500th largest eligible company within the U.S. Universe would be below $12,890 million. This threshold will change due to market conditions.

The Advisor may also increase or reduce the U.S. Sustainability Targeted Value Portfolio’s exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company’s price momentum, short-run reversals, and investment characteristics. In assessing a company’s investment characteristics, the Advisor considers ratios such as recent changes in assets divided by total assets. The criteria the Advisor uses for assessing a company’s investment characteristics are subject to change from time to time. 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. Sustainability Targeted Value 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 above referenced investment are not subject to, although they may incorporate, the Portfolio’s sustainability impact considerations.

The U.S. Sustainability Targeted Value Portfolio may lend its portfolio securities to generate additional income.

The Advisor intends to take into account the impact that companies may have on the environment and other sustainability considerations when making investment decisions for the U.S. Sustainability Targeted Value Portfolio. Relative to a portfolio without these considerations, the Portfolio will exclude, or have less weight in, securities of companies that, according to the Portfolio’s sustainability impact considerations, may be less sustainable as compared either to other companies in the Portfolio’s investment universe or other companies with similar business lines. Similarly, relative to a portfolio without sustainability impact considerations, the Portfolio will have a higher weight in securities of companies that, according to the Portfolio’s sustainability impact considerations, may be more sustainable as compared either to other companies in the Portfolio’s investment universe or other companies with similar business lines. While the Advisor primarily considers greenhouse gas emissions intensity, in evaluating sustainability impact, the Advisor will also consider fossil fuel reserves, coal, factory farming activities, tobacco, palm

oil, cluster munitions manufacturing, landmine manufacturing, civilian firearms manufacturing, the ownership or operation of private prisons and/or immigrant detention facilities, child labor, and severe environmental, social, or governance controversies that indicate operations inconsistent with responsible business conduct standards (such as those defined by the UN Global Compact Principles and the OECD Guidelines for Multinational Enterprises), among other factors. In particular, the Portfolio will exclude companies the Advisor considers to have high greenhouse gas emissions intensity or fossil fuel reserves relative to other issuers. The Advisor may engage third party service providers to provide research and/or ratings information relating to the Portfolio’s sustainability impact considerations with respect to securities in the portfolio, where information is available from such providers.

The Portfolio may periodically modify, add, or remove certain sustainability impact considerations. (See “Additional Information on Investment Objectives and Policies—Applying the Portfolios’ Sustainability Impact Considerations” in this Prospectus).
