The Russell Midcap Value Index measures the performance of U.S. mid-cap value stocks. The size of the companies in the index changes constantly with market conditions and the composition of the index. The equity securities in which the portfolio principally invests are common stocks, preferred stocks and depositary receipts, but the portfolio may invest in other types of equity securities to a lesser extent, such as securities of other investment companies (including mutual funds, exchange-traded funds and closed-end funds) that invest primarily in equity securities, equity interests in real estate investment trusts (REITs), warrants and rights. The portfolio may invest in initial public offerings of equity securities. The portfolio may invest up to 25% of its total assets in securities of non-U.S. issuers. The portfolio will not invest more than 5% of its total assets in the securities of emerging markets issuers. The portfolio may invest up to 20% of its net assets in REITs. The portfolio may invest up to 20% of its total assets in debt securities. The portfolio may invest up to 5% of its net assets in below investment grade debt securities (known as junk bonds), including below investment grade convertible debt securities. The portfolio may, but is not required to, use derivatives, such as stock index futures and options. The portfolio may use derivatives for a variety of purposes, including: in an attempt to hedge against adverse changes in the market price of securities, interest rates or currency exchange rates; as a substitute for purchasing or selling securities; to attempt to increase the portfolio's return as a non-hedging strategy that may be considered speculative; to manage portfolio characteristics; and as a cash flow management technique. The portfolio may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations. The portfolio may also hold cash or other short-term investments. The portfolio uses a value style of management. The adviser seeks to identify securities that are selling at reasonable prices or at substantial discounts to their underlying values and then holds these securities until the market values reflect their intrinsic values. The adviser evaluates a security's potential value, including the attractiveness of its market valuation, based on the company's assets and prospects for earnings growth. In making that assessment, the adviser employs fundamental research and an evaluation of the issuer based on its financial statements and operations, employing a bottom-up analytic style, which focuses on specific securities rather than on industries. The adviser focuses on the quality and price of individual issuers and securities. The adviser generally sells a portfolio security when it believes that the securitys market value reflects its underlying value. The adviser integrates environmental, social and corporate governance (ESG) considerations into its investment research process by evaluating the business models and practices of issuers and their ESG-related risks. The adviser believes ESG analysis is a meaningful facet of fundamental research, the process of evaluating an issuer based on its financial position, business operations, competitive standing and management. This process considers ESG information, where available, in assessing an investments performance potential. The adviser generally considers ESG information in the context of an issuers respective sector or industry. The adviser may consider ESG ratings provided by third parties or internal sources, as well as issuer disclosures and public information, in evaluating issuers. ESG considerations are not a primary focus of the portfolio, and the weight given by the adviser to ESG considerations in making investment decisions will vary and, for any specific decision, they may be given little or no weight. Notwithstanding the foregoing, the adviser generally will not invest portfolio assets in companies engaged in the production, sale, storage of, or providing services for, certain controversial weapons, including chemical, biological and depleted uranium weapons and certain antipersonnel mines and cluster bombs.
