Until February 29, 2024, Russell Investment Management, LLC has contractually agreed to waive up to the full amount of its advisory fee and then to reimburse the Fund for other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.67% 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, infrequent and/or unusual expenses, or the expenses of other investment companies in which the Fund invests which are borne indirectly by the Fund.

Until February 29, 2024, Russell Investments Fund Services, LLC has contractually agreed to waive 0.10% of its transfer agency fees for Class M Shares and 0.02% of its transfer agency fees for Class R6 Shares. These waivers may not be terminated during the relevant period except with Board approval.

"Total Annual Fund Operating Expenses" and "Net Annual Fund Operating Expenses" have been restated to reflect the Fund's proportionate share of the operating expenses of any other fund in which the Fund invests, including the U.S. Cash Management Fund. The Fund's proportionate share of these operating expenses are reflected under "Acquired Fund Fees and Expenses."

"Other Expenses" for Class R6 Shares are based on estimated amounts for the current fiscal year as this Share Class did not have any assets during the most recent fiscal year.

***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:

***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 158% of the average value of its portfolio.

**Investments, Risks and Performance**

***Principal Investment Strategies of the Fund***

The Fund seeks to achieve its objective by opportunistically investing in a broad range of fixed income securities across sectors, the globe and the credit quality and maturity spectrums, with an emphasis on higher-yielding securities. The Fund's fixed income investments may include U.S. and non-U.S. corporate debt securities, Yankee Bonds (dollar-denominated obligations issued in the U.S. by non-U.S. banks and corporations), fixed income securities issued or guaranteed by the U.S. government (including Treasury Inflation Protected Securities and zero coupon securities) or by non-U.S. governments, or by any U.S. government or non-U.S. government agency or instrumentality (including emerging markets sovereign debt), emerging markets debt securities (including Brady Bonds), high yield fixed income securities, investment grade fixed income securities, "distressed" debt securities and mortgage-backed and asset-backed securities. The Fund may also invest in other asset classes in order to seek to achieve its objective, including equity securities. The Fund is managed with a benchmark agnostic approach, meaning that the Fund's benchmark is not determinative of what instruments and asset classes are selected for the Fund. As a result, the Fund's relative performance may have wider deviation from the benchmark's performance than would a fund that seeks to track the performance of its benchmark.

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 a Fund's asset allocation at any time. The Fund's 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.

The Fund may invest without limitation in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund considers emerging market countries to include every country in the world except Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. Emerging market countries also include frontier market countries, which are less developed than traditional emerging market countries. The Fund may invest in currency futures and options on futures, forward currency contracts, currency swaps and currency options for speculative purposes or to seek to protect a portion of its investments against adverse currency exchange rate changes. The Fund may invest in derivative instruments and may use derivatives to take both long and short positions. The Fund's use of derivatives may cause the Fund's investment returns to be impacted by the performance of securities the Fund does not own and result in the Fund's total investment exposure exceeding the value of its portfolio. The Fund may invest in synthetic foreign fixed income securities, which may be referred to as local access products, credit linked notes and participation notes. Local access products are similar to options in that they are exercisable by the holder for an underlying security or the value of that security, but are generally exercisable over a longer term than typical options. The Fund may also purchase loans and other direct indebtedness, including bank loans (also called "leveraged loans"). The Fund

------

may enter into repurchase agreements and reverse repurchase agreements. The Fund may invest in money market securities and commercial paper, including asset-backed commercial paper. The Fund may invest in bank obligations. A portion of the Fund's net assets may be "illiquid" investments. The Fund may invest in variable and floating rate securities. The Fund may invest in puts, stand-by commitments and demand notes, including variable rate demand notes. The Fund may invest in pooled investment vehicles, including other investment companies and exchange traded funds. The Fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. Depending upon market conditions, RIM may determine to allocate a significant portion of the Fund's assets to cash in order to seek to achieve the Fund's objective. The Fund may expose all or a portion of its cash to changes in interest rates or market/sector returns by purchasing derivatives. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Fixed Income Securities*. Prices of fixed income securities generally rise and fall in response to, among other things, interest rate changes. Volatility in interest rates and in fixed income markets may increase the risk that the Fund's investments in fixed income securities could lose money. In addition, the Fund could lose money if the issuer or guarantor of a fixed income security or other issuer of credit support is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. Fixed income securities may be downgraded in credit rating or go into default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *U.S. and Non-U.S. Corporate Debt Securities Risk*. Investments in U.S. and non-U.S. corporate debt securities are subject to interest rate risk and market risk, and are affected by perceptions of the creditworthiness and business prospects of individual issuers. Non-U.S. corporate debt securities may expose the Fund to greater risk than investments in U.S. corporate debt securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Government Issued or Guaranteed Securities, U.S. Government Securities*. Bonds issued or guaranteed by a government are subject to inflation risk, price depreciation risk and default risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Non-Investment Grade Debt Securities ("High Yield" or "Junk Bonds")*. Non-investment grade debt securities involve higher volatility and higher risk of default than investment grade bonds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Currency Risk*. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S. dollar-denominated securities and currencies may reduce the returns of the Fund.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Global Financial Markets Risk.* Global economies and financial markets are becoming increasingly interconnected and conditions (including volatility and instability) and events (including natural disasters, pandemics and epidemics) 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Liquidity Risk.* The market for certain investments may become illiquid or less liquid (i.e., there may be a significant reduction in trading activity, including in the number of market participants or transactions, in such investments) under adverse or volatile market or economic conditions, making those investments difficult to sell. The market price of certain investments may fall dramatically if there is no liquid trading market. For derivatives, this also

------

includes the risk involving liquidity demands that derivatives can create to make payments of margin or settlement payments to counterparties. Such events and conditions may adversely affect the value of the Fund's investments, result in greater market or liquidity risk or cause difficulty valuing the Fund's portfolio instruments or achieving the Fund's objective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Illiquid Investments*. An illiquid or less liquid investment may be difficult to sell quickly and at a fair price, which could cause the Fund to realize a loss on the investment if it was sold at a lower price than that at which it had been valued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 RIM 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 RIM will effectively assess the Fund's portfolio characteristics and it is possible that its judgments regarding the Fund's exposures may prove incorrect. In addition, actions taken to manage Fund exposures, including risk, may be ineffective and/or cause the Fund to underperform.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Fundamental Investing Risk.* A fundamental investment approach uses research and analysis of a variety of factors to create a forecast of company results, which is used to select securities. The process may result in an evaluation of a security's value that may be incorrect or, if correct, may not be reflected by the market. Security or instrument selection using a fundamental investment approach may also cause the Fund to underperform other funds with similar investment objectives and investment strategies even in a rising market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Quantitative Investing.* Quantitative inputs and models use historical company, economic and/or industry data to evaluate prospective investments or to generate forecasts which could result in incorrect assessments of the specific portfolio characteristics or ineffective adjustments to the Fund's exposures. Securities selected using quantitative analysis may perform differently than analysis of their historical trends would suggest. Inputs or models may be flawed or not work as anticipated and may cause the Fund to underperform other funds with similar investment objectives and strategies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Derivatives*. Investments in a derivative instrument could lose more than the initial 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, and possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies or other instruments. Derivatives are generally 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), management risk, operational risk and legal risk. Certain of these risks do not apply to derivative instruments entered into for hedging or cash equitization, certain cleared derivative instruments, and written options contracts. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative instrument may not correlate exactly with the change in the value of the underlying asset, rate or index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Index-Based Investing.* Index-based strategies (including index replication which seeks to purchase the securities in an index or a blend of indexes and optimized index sampling which seeks to purchase a sampling of securities using optimization and risk models), which may be used to gain desired Fund 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Mortgage-Backed Securities*. Mortgage-backed securities may be affected by, among other things, changes or perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator of the mortgage, or the quality of the underlying assets. The underlying assets may default or decline in quality or value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Distressed Securities*. Investments in distressed securities inherently have more credit risk than investments in non-distressed issuers. In the event that an issuer of distressed securities defaults or initiates insolvency proceedings, the Fund may lose all of its investment in the distressed securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Asset-Backed Securities*. Payment of principal and interest on asset-backed securities may be largely dependent upon the cash flows generated by the assets backing the securities and asset-backed securities may not have the benefit of any security interest in the related assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Loans and Other Direct Indebtedness.* Loans and other direct indebtedness involve the risk that payment of principal, interest and other amounts due in connection with these investments may not be received. The highly leveraged nature of many such loans, including bank loans, and other direct indebtedness may make such loans and other direct indebtedness especially vulnerable to adverse changes in economic or market conditions and/or changes in the financial condition of the debtor. Investments in bank loans are typically subject to the risks of floating rate securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Non-U.S. and Emerging Markets Debt*. The value of an investment in non-U.S. and emerging markets debt may be affected by political, economic or social conditions or foreign currency exchange rates. Prices of emerging markets debt can be severely affected not only by rising interest rates and adverse currency fluctuations, but also by the deterioration of credit quality or default by the issuer. Non-U.S. and emerging markets debt may also be subject to risk of loss because of more or less foreign government regulation, less public information and less stringent investor protections and disclosure standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Money Market Securities (Including Commercial Paper)*. Prices of money market securities generally rise and fall in response to interest rate changes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Asset-Backed Commercial Paper*. Investment in asset-backed commercial paper is subject to the risk that insufficient proceeds from the projected cash flows of the contributed receivables are available to repay the commercial paper.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Repurchase Agreements*. Repurchase agreements are subject to the risk that the sellers may not be able to pay the agreed-upon repurchase price on the repurchase date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Yankee Bonds and Yankee CDs*. Issuers of Yankee Bonds and Yankee CDs are not necessarily subject to the same regulatory requirements that apply to U.S. corporations and banks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Synthetic Foreign Equity/Fixed Income Securities*. Investments in these instruments involve the risk that the issuer of the instrument may default on its obligation to deliver the underlying security or its value. These instruments may also be subject to liquidity risk, currency risk and the risks associated with investments in non-U.S. securities. In addition, the exercise or settlement date may be affected by certain market disruption events which could cause the local access products to become worthless if the events continue for a period of time.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Variable and Floating Rate Securities Risk.* Variable and floating rate securities generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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. Investments in preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Puts, Stand-by Commitments and Demand Notes.* The ability of the Fund to exercise a put or stand-by commitment may depend on the seller's ability to purchase the securities at the time the put or stand-by commitment is exercised or on certain restrictions in the buy back arrangement. If there is a shortfall in the anticipated proceeds from demand notes, including variable rate demand notes, the notes may not be fully repaid and the Fund may lose money.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Reverse Repurchase Agreements*. Reverse repurchase agreements are subject to the risk that the other party may fail to return the security in a timely manner or at all. The Fund may lose money if the market value of the security transferred by the Fund declines below the repurchase price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Securities of Other Investment Companies.* Investments in other investment companies expose shareholders to the expenses and risks associated with the investments of the Fund as well as to the expenses and risks of the underlying investment companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Counterparty Risk.* Counterparty risk is the risk that the other party or parties to an agreement or a participant to a transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *High Portfolio Turnover Risk*. The Fund may engage in active and frequent trading, which may result in higher portfolio turnover rates, higher transaction costs and realization of short-term capital gains that will generally be taxable to shareholders as ordinary income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Currency Trading Risk.* Currency trading strategies may involve instruments that have volatile prices, are illiquid or less liquid or create economic leverage. Forward currency contracts are subject to the risk that, should forward prices increase, a loss will be incurred to the extent that the price of the currency agreed to be purchased exceeds the price of the currency agreed to be sold.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Impact of Large Redemptions (Including Possible Fund Liquidation)*. The Fund is used as an investment by certain funds of funds and in asset allocation programs and may have a large percentage of its Shares owned by such funds or 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. Large redemptions may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher Fund cash levels, higher brokerage commissions and other transaction costs, among other negative consequences such as reduced liquidity in the Fund's portfolio. As a result, large redemption activity could adversely affect the Fund's ability to conduct its investment program which, in turn, could adversely impact the Fund's performance or may result in the Fund no longer remaining at an economically viable size, in which case the Fund may cease operations.

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 total 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. After-tax returns reflect foreign tax credits passed by the Fund to its shareholders thereby increasing total returns after taxes on distributions and total returns after taxes on distributions and sale of Fund Shares. 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.

***How to Purchase Shares***

Shares are only available through a select network of banks (including bank trust departments), registered investment advisers, broker-dealers and other financial services organizations (collectively, "Financial Intermediaries"), unless you are eligible to participate in a Russell Investments employee investment program. Certain Classes of Shares may only be purchased by specified categories of investors and are only offered by certain Financial Intermediaries. There is currently no required minimum initial investment for Class A, Class C, Class M, Class R6 or Class S Shares. For Class Y Shares, there is a $10 million minimum initial investment for each account in each Fund. However, for Class Y Shares there is no required minimum initial investment for specified categories of investors. Each Fund reserves the right to close any account whose balance falls below $500 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 (defined as 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 normally be received by a Fund or a Fund agent prior to the close of regular trading on the NYSE

------

(normally 4:00 p.m., Eastern Time) on a business day of the Fund, in order 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 Fund prior to the Fund's 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.
