The Fund considers bonds to include fixed income equivalent instruments, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. Russell Investment Management, LLC ( RIM ) provides or oversees the provision of all investment advisory and portfolio management services for the Fund. The Fund is advised by RIM and multiple money managers unaffiliated with RIM pursuant to a multi-manager approach. RIM may change the Funds asset allocation at any time. The Funds money managers select the individual portfolio instruments for the assets assigned to them. RIM manages assets not allocated to money manager strategies and utilizes quantitative and/or rules-based processes and qualitative analysis to assess Fund characteristics and invest in securities and instruments which provide the desired exposures. RIM may use strategies based on indexes. RIM also manages the Fund's cash balances. RIM determines the Funds allocations to fixed income sectors, money manager strategies and RIMs strategies based on RIMs target strategic asset allocation, portfolio construction tools and Fund-level guidelines. The portfolio construction process involves an analysis of tradeoffs between various risk and return factors as well as turnover and transaction costs to estimate optimal portfolio positioning. The Fund invests principally in short duration bonds and defines short duration as a duration ranging from zero to three years. The Fund has no restrictions on individual security duration. The Fund has no restrictions on the maturity of securities in which it invests or on the maturity of its overall portfolio.
