Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy and hold Shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Russell Funds. More information about these and other discounts is available from your financial professional and in the Front-End Sales Charges section and the More About Deferred Sales Charges section beginning on pages 228 and 230, respectively, of the Prospectus, and the Purchase, Exchange and Redemption of Fund Shares section, beginning on page 27 of the Fund’s Statement of Additional Information.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)#

	Class A Shares	Class C Shares	Class S Shares
Advisory Fee	0.80%	0.80%	0.80%
Distribution (12b-1) Fees	0.25%	0.75%	None
Other Expenses	0.37%	0.62%	0.37%
Total Annual Fund Operating Expenses	1.42%	2.17%	1.17%

Net Annual Fund Operating Expenses	1.22%	1.97%	0.97%

(See footnotes on next page)

Until February 29, 2016, Russell Investment Management Company (“RIMCo”) has contractually agreed to waive up to the full amount of its 0.80% advisory fee and then to reimburse the Fund for other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.77% of the average daily net assets of the Fund on an annual basis. This waiver and reimbursement may not be terminated during the relevant period except with Board approval. Direct Fund-level expenses do not include 12b-1 fees, shareholder services fees, transfer agency fees, extraordinary expenses or the expenses of other investment companies in which the Fund invests which are borne indirectly by the Fund.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that operating expenses remain the same. The calculation of costs for the one year period takes into account the effect of any current contractual fee waivers and/or reimbursements. The calculation of costs for the remaining periods takes such fee waivers and/or reimbursements into account only for the first year of the periods.

Although your actual costs may be higher or lower, under these assumptions your costs would be:

	Class A Shares	Class C Shares	Class S Shares
1 Year	$ 692	$ 200	$ 99
3 Years	$ 980	$ 660	$ 352
5 Years	$1,289	$1,146	$ 624
10 Years	$2,163	$2,488	$1,403

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 96% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies of the Fund

The Fund has a non-fundamental policy to invest, under normal circumstances, at least 80% of the value of its net assets plus borrowings for investment purposes in medium capitalization equity securities economically tied to the U.S. The Fund invests principally in common stocks of medium capitalization U.S. companies but may also invest in common stocks of small capitalization companies. The Fund defines medium capitalization stocks as stocks of those companies represented by the Russell MidCap^® Index or within the capitalization range of the Russell MidCap^® Index. The Fund employs a multi-style (growth, value, market-oriented, defensive and dynamic) and multi-manager approach whereby portions of the Fund are allocated to different money managers who employ distinct investment styles. Fund assets not allocated to money managers are managed by Russell Investment Management Company (“RIMCo”). Assets not allocated to money managers include the Fund's liquidity reserves and assets which may be managed directly by RIMCo to effect the Fund's investment strategies and/or to actively manage the Fund's overall exposures by investing in securities or other instruments that RIMCo believes will achieve the desired risk/return profile for the Fund. RIMCo may use strategies based on indexes that represent the desired exposures, including index replication and optimized index sampling, or utilize quantitative or qualitative analysis or quantitative models designed to assess Fund characteristics and identify a portfolio which provides the desired exposures. 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. The Fund may invest in securities of non-U.S. issuers by purchasing American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”). The Fund may also invest a portion of its assets in securities of companies, known as real estate investment trusts (“REITs”), that own and/or manage properties. Please refer to the “Investment Objective and Investment Strategies” section in the Fund's Prospectus for further information.

Principal Risks of Investing in the Fund

An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose money. The principal risks of investing in the Fund are those associated with:

•	Active Management. Despite strategies designed to achieve the Fund’s investment objective, the value of investments will change with market conditions, and so will the value of any investment in the Fund and you could lose money. The securities selected for the portfolio may not perform as RIMCo or the Fund's money managers expect. Additionally, securities selected may cause the Fund to underperform relative to other funds with similar investment objectives and strategies. There is no guarantee that RIMCo will effectively assess the Fund's portfolio characteristics and it is possible that its judgments regarding the Fund's risk/return profile may prove incorrect. In addition, actions taken to actively manage overall Fund exposures, including risk, may be ineffective and/or cause the Fund to underperform.
•	Multi-Manager Approach. While the investment styles employed by the money managers are intended to be complementary, they may not in fact be complementary. A multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
•	Index-Based Investing. Index-based strategies, which may be used to actively manage the Fund's overall exposures, may cause the Fund's returns to be lower than if the Fund employed a fundamental investment approach to security selection with respect to that portion of its portfolio. Additionally, index-based strategies are subject to “tracking error” risk, which is the risk that the performance of the portion of the Fund's portfolio utilizing an index-based strategy will differ from the performance of the index it seeks to track.
•	Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that issued them, general market conditions and/or economic conditions. Investments in small and medium capitalization companies may involve greater risks because these companies generally have narrower markets, more limited managerial and financial resources and a less diversified product offering than larger, more established companies. Small and some medium capitalization stocks may also be thinly traded, and thus, difficult to buy and sell in the market.
•	American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”). ADRs and GDRs have the same currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks associated with non-U.S. securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies.
•	Real Estate Investment Trusts (“REITs”). REITs may be affected by changes in the value of the underlying properties owned by the REITs and by the quality of tenants’ credit.
•	Derivatives. Investments in a derivative instrument could lose more than the principal amount invested. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies or other investments. Derivatives are subject to a number of risks such as leveraging risk, liquidity risk, market risk, credit risk, default risk, counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate exactly with the change in the value of the underlying asset, rate or index.
•	Large Redemptions. The Fund is used as an investment in asset allocation programs and may have a large percentage of its Shares held in such programs. Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions.
•	Global Financial Markets Risk. Global economies and financial markets are becoming increasingly interconnected and conditions (including recent volatility and instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market. In addition, governmental and quasi-governmental organizations have taken a number of unprecedented actions designed to support the markets. Such events and conditions may adversely affect the value of the Fund’s securities, result in greater market or liquidity risk or cause difficulty valuing the Fund’s portfolio instruments or achieving the Fund’s objective.

•

Long-Term Viability Risk. There can be no assurance that the Fund will grow to an economically viable size, in which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer their investments at an inopportune time. You should consider your own investment goals and risk tolerance before investing in any Fund.

Please refer to the “Risks” section in the Fund’s Prospectus for further information.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance

The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund’s Class S Shares varies from year to year over a 10-year period (or if the Fund has not been in operation for 10 years, since the beginning of the Fund’s operations). The returns (both before and after tax) for other Classes of Shares offered by this Prospectus may be lower than the returns shown in the bar chart, depending upon the fees and expenses of those Classes. The highest and lowest returns for a full quarter during the periods shown in the bar chart are set forth next to the bar chart.

The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the Fund’s average annual returns for the periods shown compare with the returns of one or more indexes that measure broad market performance. After-tax returns are shown only for one class. The after-tax returns for other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. If the Fund has realized capital losses, the total return after taxes on distributions and sale of Fund Shares may be higher than the total return before taxes and the total return after taxes on distributions. For more information, see the Performance Notes section in the Fund’s Prospectus.

Past performance, both before-tax and after-tax, is no indication of future results. More current performance information is available at www.russell.com.

• Ceredex Value Advisors LLC	• Jacobs Levy Equity Management, Inc.
• Elk Creek Partners, LLC

Portfolio Managers

Jon Eggins, a Senior Portfolio Manager, and Megan Roach, a Portfolio Manager, have primary responsibility for the management of the Fund. Mr. Eggins has managed the Fund since December 2013 and Ms. Roach has managed the Fund since March 2015.

Additional Information

How to Purchase Shares

Unless you are eligible to participate in a Russell employee investment program, Shares are only available through a select network of Financial Intermediaries. Class S Shares of the Funds may only be purchased by specified categories of investors. There is currently no required minimum initial investment for Class A, Class C or Class S Shares. Each Fund reserves the right to close any account whose balance falls below $1,000 and to change the categories of investors eligible to purchase its Shares.

For more information about how to purchase Shares, please see Additional Information about How to Purchase Shares in the Funds' Prospectus.

How to Redeem Shares

Shares may be redeemed through your Financial Intermediary on any business day of the Funds (a day on which the New York Stock Exchange (“NYSE”) is open for regular trading). Redemption requests are processed at the next net asset value per share calculated after a Fund receives an order in proper form as determined by your Financial Intermediary. Redemption requests must be received by a Fund or a Fund agent prior to 4:00 p.m. Eastern Time or the close of the NYSE, whichever is earlier, to be processed at the net asset value calculated on that day. Because Financial Intermediaries and Fund agents may have earlier redemption order cut off times to allow them to deliver redemption orders to the Funds prior to the Funds’ order transmission cut off time, please ask your Financial Intermediary what the cut off time is. Please contact your Financial Intermediary for instructions on how to place redemption requests.

For more information about how to redeem Shares, please see Additional Information about How to Redeem Shares in the Funds' Prospectus.

Taxes

Unless you are investing through an IRA, 401(k) or other tax-advantaged retirement account, distributions from a Fund are generally taxable to you as either ordinary income or capital gains.

For more information about these and other tax matters relating to each Fund and its shareholders, please see Additional Information about Taxes in the Funds' Prospectus.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares of a Fund through a broker-dealer or other Financial Intermediary (such as a bank), a Fund and its related companies may pay the intermediary for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend a Fund over another investment. Ask your salesperson or visit your Financial Intermediary’s Web site for more information.

For more information about payments to broker-dealers and other Financial Intermediaries please see Distribution and Shareholder Services Arrangements and Payments to Financial Intermediaries in the Funds' Prospectus.
