 Example

The following 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 illustrates the hypothetical expenses that you would incur over the time periods indicated, and assumes that:

Class C shares' 10-year cost examples below reflect the Class C shares' 8-year conversion policy.
Since the waivers and/or reimbursements shown in the Annual Fund Operating Expenses table above expire as indicated in the preceding table, they are only reflected in the 1 year example and the first year of the other examples. Although your actual costs may be higher or lower, based on the assumptions listed above, your costs would be: 

	1 year	3 years	5 years	10 years
Class A (whether or not shares are redeemed)	$568	$785	$1,019	$1,689
Class C (assuming redemption of all shares at the end of the period)	$274	$558	$966	$1,911
Class C (assuming no redemption of shares)	$174	$558	$966	$1,911
Class Inst (whether or not shares are redeemed)	$73	$246	$435	$981
Class Inst2 (whether or not shares are redeemed)	$65	$227	$402	$909
Class Inst3 (whether or not shares are redeemed)	$60	$211	$374	$849
Class R (whether or not shares are redeemed)	$123	$403	$704	$1,560
Class S (whether or not shares are redeemed)	$73	$246	$435	$981

Portfolio Turnover

The Fund may pay 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 49% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in high-yield debt instruments (commonly referred to as "junk" bonds or securities). These high yield debt instruments include corporate debt securities as well as floating rate loans rated below investment grade by nationally recognized statistical rating organizations, or if unrated, determined to be of comparable quality.

The Fund may invest up to 25% of its net assets in debt instruments of foreign issuers.

Corporate debt instruments in which the Fund invests are typically unsecured, with a fixed-rate of interest, and are usually issued by companies or similar entities to provide financing for their operations, or other activities. Floating rate loans, which are another form of financing, are typically secured, with interest rates that adjust or "float" periodically (normally on a daily, monthly, quarterly or semiannual basis by reference to a base lending rate, plus a premium).

The Fund may invest in debt instruments of any maturity and does not seek to maintain a particular dollar-weighted average maturity. Because the Fund emphasizes high-yield investments, more emphasis is put on credit risk by the portfolio managers in selecting investments than either maturity or duration.

The Fund may invest in privately placed and other securities or instruments that are purchased and sold pursuant to Rule 144A or other exemptions under the Securities Act of 1933, as amended, subject to certain regulatory restrictions.

Principal Risks

An investment in the Fund involves risks, including High-Yield Investments Risk, Interest Rate Risk, Changing Distribution Level Risk, Credit Risk, and Market Risk, among others. Descriptions of these and other principal risks of investing in the Fund are provided below. There is no assurance that the Fund will achieve its investment objective and you may lose money. The value of the Fund's holdings may decline, and the Fund's net asset value (NAV) and share price may go down. 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. 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.

Active Management Risk. Due to its active management, the Fund could underperform its benchmark index and/or 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.

Confidential Information Access Risk. The portfolio managers may avoid the receipt of material, non-public information (Confidential Information) about the issuers of floating rate loans (including from the issuer itself) being considered for acquisition by the Fund, or held in the Fund. A decision not to receive Confidential Information may disadvantage the Fund and could adversely affect the Fund's performance.

Counterparty Risk. Counterparty risk is the risk that a counterparty to a transaction in a financial instrument held by the Fund or by a special purpose or structured vehicle invested in by the Fund may become insolvent or otherwise fail to perform its obligations. As a result, the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Credit Risk. Credit risk is the risk that the value of loans or other debt instruments may decline if the borrower or the issuer thereof 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, such as S&P Global Ratings, Moody's Investors Service, Inc. (Moody's Ratings), Fitch Ratings, Inc. (Fitch), Morningstar DBRS (DBRS) and Kroll Bond Rating Agency, LLC (KBRA), assign credit ratings to certain loans and debt instruments to indicate their credit risk. A rating downgrade by such agencies can negatively impact the value of such instruments. Lower-rated or unrated loans or instruments held by the Fund may present increased credit risk as compared to higher-rated loans or instruments. Non-investment grade loans or debt instruments may be subject to greater price fluctuations and are more likely to experience a default than investment grade loans or debt instruments and therefore may expose the Fund to increased credit risk. If the Fund purchases unrated loans or instruments, or if the ratings of loans or instruments held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual. If the issuer of a loan or debt instrument declares bankruptcy or is declared bankrupt, there may be a delay before the Fund can act on the collateral (if any) securing the loan or debt instrument, which may adversely affect the Fund. Further, there is a risk that a court could take action with respect to a loan or debt instrument that is adverse to the holders of the loan or debt instrument. Such actions may include invalidating the loan or debt instrument, the lien on the collateral (if any), the priority status of the loan or debt instrument, or ordering the refund of interest previously paid by the borrower. Any such actions by a court could adversely affect the Fund's performance. A default or expected default of a loan or debt instrument could also make it difficult for the Fund to sell the loan or debt instrument at a price approximating the value previously placed on it. In order to enforce its rights in the event of a default, bankruptcy or similar situation, the Fund may be required to retain legal or similar counsel. This may increase the Fund's operating expenses and adversely affect its NAV. Loans or debt instruments that have a lower priority for repayment in an issuer's capital structure typically involve a higher degree of overall risk than more senior loans or debt instruments of the same borrower.

Fixed Income Instruments Risk. The Fund is subject to the general risks and considerations associated with investing in debt securities, including the risk that issuers will fail to make timely payments of principal or interest or default altogether. Lower-rated securities in which the Fund may invest may be more volatile and may decline more in price in response to negative issuer developments or general economic news than higher rated securities. In addition, as interest rates rise, the Fund's investments typically will lose value.

Foreign Securities Risk. Investments in or exposure to securities of foreign companies may involve heightened risks relative to investments in or exposure to securities of U.S. companies. Investing in securities of foreign companies subjects the Fund to the risks associated with an issuer's (and any of its related companies') country of organization

3

Columbia High Yield Bond Fund

and places of business operations, including risks related to political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism and disease/virus outbreaks and epidemics) occurring in the country or region, as well as risks associated with less developed custody and settlement practices. Foreign securities may be more volatile and less liquid than securities of U.S. companies and are subject to the risks associated with potential imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country. In addition, foreign governments may impose withholding or other taxes on the Fund's income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund's return on such securities. The performance of the Fund may also be negatively affected by fluctuations in a foreign currency's strength or weakness relative to the U.S. dollar, particularly to the extent the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar.

High-Yield Investments Risk. Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called "high-yield" or "junk" bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer's capacity to pay interest and repay principal.

Highly Leveraged Transactions Risk. The loans or other debt instruments in which the Fund invests may include highly leveraged transactions whereby the borrower assumes large amounts of debt in order to have the financial resources to attempt to achieve its business objectives. Loans or other debt instruments that are part of highly leveraged transactions involve a greater risk (including default and bankruptcy) than other investments.

Impairment of Collateral Risk. The value of collateral, if any, securing a loan can decline, and may be insufficient to meet the borrower's obligations or difficult or costly to liquidate. In addition, the Fund's access to collateral may be limited by bankruptcy or other insolvency laws. Further, certain floating rate and other loans may not be fully collateralized and may decline in value.

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 loans and other debt instruments tend to fall, and if interest rates fall, the values of loans and other 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. Changes in interest rates may also affect the liquidity of the Fund's investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. For example, a three-year duration means a bond is expected to decrease in value by 3% if interest rates rise 1% and increase in value by 3% if interest rates fall 1%. 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 or decreases 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. Any interest rate increases could cause the value of the Fund's investments in debt instruments to decrease. 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.

Issuer Risk. An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations, and the value of its loans or securities may therefore decline, which may negatively affect the Fund's performance. Underperformance of an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations and actions, war, other conflicts, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of your investment in the Fund.

Liquidity Risk. Liquidity risk is the risk associated with any event, circumstance, or characteristic of an investment or market that negatively impacts the Fund's ability to sell, or realize the proceeds from the sale of, an investment at a desirable time or price. Liquidity risk may arise because of, for example, a lack of marketability of the investment, which means that when seeking to sell its portfolio investments, the Fund could find that selling is more difficult than anticipated, especially during times of high market volatility. Decreases in the number of financial institutions, including banks and broker-dealers, willing to make markets (match up sellers and buyers) in the Fund's investments or decreases in their capacity or willingness to trade such investments may increase the Fund's exposure to this risk. The debt market has experienced considerable growth, and financial institutions making markets in instruments purchased and sold by the Fund (e.g., bond dealers) have been subject to increased regulation. The impact of that growth and regulation on the ability and willingness of financial institutions to engage in trading or "making a

Columbia High Yield Bond Fund

market" in such instruments remains unsettled. Certain types of investments, such as lower-rated securities or those that are purchased and sold in over-the-counter markets, may be especially subject to liquidity risk. Securities or other assets in which the Fund invests may be traded in the over-the-counter market rather than on an exchange and therefore may be more difficult to purchase or sell at a fair price, which may have a negative impact on the Fund's performance. Market participants attempting to sell the same or a similar instrument at the same time as the Fund could exacerbate the Fund's exposure to liquidity risk. The Fund may have to accept a lower selling price for the holding, sell other liquid or more liquid investments that it might otherwise prefer to hold (thereby increasing the proportion of the Fund's investments in less liquid or illiquid securities), or forgo another more appealing investment opportunity. The liquidity of Fund investments may change significantly over time and certain investments that were liquid when purchased by the Fund may later become illiquid, particularly in times of overall economic distress. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may also adversely affect the liquidity and the price of the Fund's investments. Judgment plays a larger role in valuing illiquid or less liquid investments as compared to valuing liquid or more liquid investments. Price volatility may be higher for illiquid or less liquid investments as a result of, for example, the relatively less frequent pricing of such securities (as compared to liquid or more liquid investments). Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. Overall market liquidity and other factors can lead to an increase in redemptions, which may negatively impact Fund performance and NAV, including, for example, if the Fund is forced to sell investments in a down market. Floating rate loans generally are subject to legal or contractual restrictions on resale, may trade infrequently, their value may be impaired when the Fund needs to liquidate such loans, and are typically subject to extended settlement periods, each of which gives rise to liquidity risk.

Loan Interests Risk. Loan interests may not be considered "securities," and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Loan interests generally are subject to restrictions on transfer, and the Fund may be unable to sell its loan interests at a time when it may otherwise be desirable to do so or may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Accordingly, loan interests may at times be illiquid. Loan interests may be difficult to value and typically have extended settlement periods (generally greater than 7 days). Extended settlement periods during significant Fund redemption activity could potentially cause increased short-term liquidity demands on the Fund. As a result, the Fund may be forced to sell investments at unfavorable prices, or borrow money or effect short settlements where possible (at a cost to the Fund), in an effort to generate sufficient cash to pay redeeming shareholders. The Fund's actions in this regard may not be successful. Interests in loans created to finance highly leveraged companies or transactions, such as corporate acquisitions, may be especially vulnerable to adverse changes in economic or market conditions. Interests in secured loans have the benefit of collateral and, typically, of restrictive covenants limiting the ability of the borrower to further encumber its assets. There is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In the event the borrower defaults, the Fund's access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Further, there is a risk that a court could take action with respect to a loan that is adverse to the holders of the loan, and the Fund, to enforce its rights in the event of a default, bankruptcy or similar situation, may need to retain legal or similar counsel. This may increase the Fund's operating expenses and adversely affect its NAV. Loans that have a lower priority for repayment in an issuer's capital structure may involve a higher degree of overall risk than more senior loans of the same borrower. In the event of a default, second lien secured loans will generally be paid only if the value of the collateral exceeds the amount of the borrower's obligations to the first lien secured lenders, and the remaining collateral may not be sufficient to cover the full amount owed on the loan in which the Fund has an interest. The Fund may acquire a participation interest in a loan that is held by another party. When the Fund's loan interest is a participation, the Fund may have less control over the exercise of remedies than the party selling the participation interest, and it normally would not have any direct rights against the borrower.

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

5

Columbia High Yield Bond Fund

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.

Prepayment and Extension Risk. Prepayment and extension risk is the risk that a loan, bond or other security or investment might, in the case of prepayment risk, be called or otherwise converted, prepaid or redeemed before maturity and, in the case of extension risk, that the investment might not be called as expected. In the case of prepayment risk, if the investment is converted, prepaid or redeemed before maturity, the portfolio managers may not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced yield to the Fund. As interest rates decrease or spreads narrow on such investments, the likelihood of prepayment increases. Conversely, extension risk is the risk that an unexpected rise in interest rates will extend the life of an investment beyond the prepayment time. If the Fund's investments are locked in at a lower interest rate for a longer period of time, the portfolio managers may be unable to capitalize on investments with higher interest rates or wider spreads.

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.

Rule 144A and Other Exempted Securities Risk. The Fund may invest in privately placed and other securities or instruments exempt from SEC registration (collectively "private placements"), subject to certain regulatory restrictions. In the U.S. market, private placements are typically sold only to qualified institutional buyers, or qualified purchasers, as applicable. An insufficient number of buyers interested in purchasing private placements at a particular time could adversely affect the marketability of such investments and the Fund might be unable to dispose of them promptly or at reasonable prices, subjecting the Fund to liquidity risk. The Fund's holdings of private placements may increase the level of Fund illiquidity if eligible buyers are unable or unwilling to purchase them at a particular time. Issuers of Rule 144A eligible securities are required to furnish information to potential investors upon request. However, the required disclosure is much less extensive than that required of public companies and is not publicly available since the offering information is not filed with the SEC. Further, issuers of Rule 144A eligible securities can require recipients of the offering information (such as the Fund) to agree contractually to keep the information confidential, which could also adversely affect the Fund's ability to dispose of the security.

Unrated Securities Risk. The Fund may purchase unrated securities which are not rated by a rating agency. Unrated securities may be less liquid than comparable rated securities and involve the risk that the Fund's investment manager may not accurately evaluate the security's comparative credit rating. Analysis of creditworthiness of issuers of high yield securities may be more complex than for issuers of higher-quality debt securities. To the extent that the Fund purchases unrated securities, the Fund's success in achieving its investment objective may depend more heavily on the Fund's investment manager's creditworthiness analysis than if the Fund invested exclusively in rated securities.

These distributions are generally taxable to you as ordinary income or capital gains, unless you are investing through a tax-advantaged account, such as a 401(k) plan or an IRA. 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.
