The Fund considers a company to be a real estate company if it is included in the Global Industry Classification Standard (GICS) real estate sector. The Fund seeks to achieve its objective by investing in equity securities of real estate companies economically tied to the U.S. In determining if a security is economically tied to the U.S., the Fund generally looks to the country of risk of the issuer as determined by a third party such as Bloomberg L.P. The Fund invests principally in securities of companies, known as real estate investment trusts (REITs) and other REIT-like entities, that own interests in real estate or real estate-related loans. The Fund may also invest in equity securities of other types of real estate-related companies. The Fund concentrates (i.e., invests greater than 25% of its net assets) in companies in the real estate industry. The Fund may invest in large, medium or small capitalization companies. The Adviser has engaged Russell Investment Management, LLC ("RIM") to provide the day-to-day management of the Fund's portfolio pursuant to a multi-style and multi-manager approach and investment guidelines provided by the Adviser. The Fund seeks to achieve its investment objective by allocating its assets among a number of different investment strategies (or "sleeves"), each of which is advised by RIM or by RIM and a non-discretionary sub-adviser that provides the Adviser and RIM with investment recommendations in the form of a model portfolio, which RIM utilizes to purchase and sell securities for the Fund. The non-discretionary sub-advisers utilize different investment strategies in providing investment recommendations for their respective sleeves, act independently from one another, and use their own methodologies for selecting investments. Non-discretionary sub-advisers may employ a fundamental investment approach, a quantitative investment approach, or a combination of both. The Fund's use of such model portfolios and the allocation of Fund assets may change at any time. RIM also manages the Fund's cash balances and may manage portions of the Fund during transitions between non-discretionary sub-adviser strategies. The Fund usually, but not always, pursues a strategy to be fully invested by exposing all or a portion of its cash to the performance of appropriate markets by purchasing equity securities and/or derivatives, which typically include index futures contracts.
