Columbia Government Money Market Fund

Principal Investment Strategies

The Fund invests at least 99.5% of its total assets in government securities, cash and/or repurchase agreements collateralized solely by government securities or cash. For purposes of this policy, "government securities" are any securities issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the Government of the United States pursuant to authority granted by the Congress of the United States, or any certificate of deposit for any of the foregoing.

The Fund typically invests in U.S. Treasury bills, notes and other obligations issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, and repurchase agreements secured by such obligations. The Fund may invest in variable and floating rate instruments, and may transact in securities on a when-issued, delayed delivery or forward commitment basis (including U.S. Treasury floating rate notes). The Fund invests in a portfolio of securities maturing in 397 days or less (as maturity is calculated by U.S. Securities and Exchange Commission (SEC) rules governing the operation of money market funds) that will have a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less.

The securities purchased by the Fund are subject to the quality, diversification, and other requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended (the 1940 Act), and other rules of the SEC. Under normal market conditions, the Fund invests at least 80% of its net assets (including the amount of any borrowings for investment purposes) in government securities and/or repurchase securities that are collateralized by government securities. The Fund will only purchase government securities, cash, repurchase agreements collateralized solely by government securities or cash, and up to 0.5% of the Fund's total assets may be invested in other securities that present minimal credit risk as determined by Columbia Management Investment Advisers, LLC, the Fund's investment manager (the Investment Manager), pursuant to guidelines approved by the Fund's Board of Trustees.

Principal Risks

An investment in the Fund involves risks, including Money Market Fund Risk, U.S. Government Obligations Risk, Interest Rate Risk, Credit Risk, and Market Risk, among others. Descriptions of these and other principal risks of investing in the Fund are provided below. The significance of any specific risk to an investment in the Fund will vary over time depending on the composition of the Fund's portfolio, market conditions, and other factors. You should read all of the risk information below carefully, because any one or more of these risks may result in losses to the Fund.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the net asset value (NAV) of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. The Fund's sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

Active Management Risk. Due to its active management, the Fund could underperform other funds with similar investment objectives and/or strategies.

Changing Distribution Level Risk. The Fund normally expects to receive income which may include interest, dividends and/or capital gains, depending upon its investments. The distribution amounts paid by the Fund will vary and generally depend on the amount of income the Fund earns (less expenses) on its portfolio holdings, and capital gains or losses it recognizes. A decline in the Fund's income or net capital gains arising from its investments may reduce its distribution level.

Credit Risk. Credit risk is the risk that the value of a security or instrument in the Fund's portfolio may or will decline if the issuer fails to pay interest or repay principal when due. The value of debt instruments may decline if the issuer of the instrument defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Unrated instruments held by the Fund may present increased credit risk as compared to higher-rated instruments. If the Fund purchases unrated instruments, or if the ratings of instruments held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases in interest rates. Higher periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund's performance and NAV. The Fund's yield will vary; it is not fixed for a specific period like the yield on a bank certificate of deposit. Under certain circumstances, the yield decline could

cause the Fund's net yield to be negative (such as when Fund expenses exceed income levels). Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund's ability to price or value hard-to-value assets in thinly traded and closed markets and could cause significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events - or the potential for such events - could have a significant negative impact on global economic and market conditions.

Money Market Fund Risk. Although government money market funds (such as the Fund) may seek to preserve the value of shareholders' investment at $1.00 per share, the NAVs of such money market fund shares can fall, and in infrequent cases in the past have fallen, below $1.00 per share, potentially causing shareholders who redeem their shares at such NAVs to lose money from their original investment.

At times of (i) significant redemption activity by shareholders, including, for example, when a single investor or a few large investors make a significant redemption of Fund shares, (ii) insufficient levels of cash in the Fund's portfolio to satisfy redemption activity, and (iii) disruption in the normal operation of the markets in which the Fund buys and sells portfolio securities, the Fund could be forced to sell portfolio securities at unfavorable prices in order to generate sufficient cash to pay redeeming shareholders. Sales of portfolio securities at such times could result in losses to the Fund and cause the NAV of Fund shares to fall below $1.00 per share. Additionally, in some cases, the default of a single portfolio security could cause the NAV of Fund shares to fall below $1.00 per share. In addition, neither the Investment Manager nor any of its affiliates has a legal obligation to provide financial support to the Fund, and you should not expect that they or any person will provide financial support to the Fund at any time. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds. Managing the Fund in compliance with regulatory limitations recently imposed on money market funds may limit the Fund's yield.

Reinvestment Risk. Reinvestment risk arises when the Fund is unable to reinvest income or principal at the same or at least the same return it is currently earning.

Repurchase Agreements Risk. Repurchase agreements are agreements in which the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon price and time. Repurchase agreements carry the risk that the counterparty may not fulfill its obligations under the agreement. This could cause the Fund's income and the value of your investment in the Fund to decline.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the "full faith and credit" of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

When-Issued, Delayed Settlement and Forward Commitment Transactions, Including U.S. Treasury Floating Rate Notes Risk. When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future - i.e., beyond normal settlement. A Fund does not earn interest on such securities until settlement and bears the risk of market value fluctuations in between the purchase and settlement dates. Such transactions include floating rate obligations issued by the U.S. Treasury. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their coupon rates do not reset as high, or as quickly, as interest rates in general, and generally carry lower yields than fixed notes of the same maturity.

Performance Information

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund's Class A share performance has varied for each full calendar year shown.

Columbia Government Money Market Fund

The performance of one or more share classes shown in the table below begins before the indicated inception date for such share class. The returns shown for each such share class include the returns of the Fund's Class A shares for periods prior to its inception date.

Except for differences in annual returns resulting from differences in expenses and sales charges (where applicable), the share classes of the Fund would have substantially similar annual returns because all share classes of the Fund invest in the same portfolio of securities.

Prior to October 1, 2016, the Fund operated as a prime money market fund and invested in certain types of securities that the Fund is no longer permitted to hold to any significant extent (i.e., over 0.5% of total assets). Consequently, the performance information may have been different if the current investment limitations had been in effect during the period prior to the Fund's conversion to a government money market fund.

The Fund's past performance is no guarantee of how the Fund will perform in the future. Updated performance information, including current 7-day yield, can be obtained by calling toll-free 800.345.6611 or visiting columbiathreadneedleus.com.

If you are investing through a tax-advantaged account, you may be taxed upon withdrawals from that account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies - including Columbia Management Investment Advisers, LLC (the Investment Manager), Columbia Management Investment Distributors, Inc. (the Distributor) and Columbia Management Investment Services Corp. (the Transfer Agent) - 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 financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
