Disclosures

Columbia Adaptive Risk Allocation Fund
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The fund’s investment in other funds subjects it to the investment performance (positive or negative), risks and expenses of these underlying funds. Asset allocation does not assure a profit or protect against loss. Investing in derivatives is a specialized activity that involves special risks that subject the fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Commodityinvestments may be affected by the overall market and industry- and commodity-specific factors, and may be more volatile and less liquid than other investments. Short positions (where the underlying asset is not owned) can create unlimited risk. International investing involves certain risks and volatility due to potential political, economic or currency instabilities and different financial and accounting standards. Risks are enhanced for emerging marketissuers. Investment in or exposure to foreign currencies subjects the fund to currency fluctuation and risk of loss. Investments in small- and mid-capcompanies involve risks and volatility greater than investments in larger, more established companies. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the fund, negatively impacting its performance and NAV. Falling rates may result in the fund investing in lower yielding debt instruments, lowering the fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Interest payments on inflation-protected securities may be more volatile than interest paid on ordinary bonds. In periods of deflation, these securities provide no income. As a non-diversified fund, fewer investments could have a greater effect on performance. Investments selected using quantitative methods may perform differently from the market as a whole and may not enable the fund to achieve its objective. Market or other (e.g., interest rate) environments may adversely affect the liquidity of fund investments, negatively impacting their price. Generally, the less liquid the market at the time the fund sells a holding, the greater the risk of loss or decline of value to the fund.

Columbia Total Return Bond Fund
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the fund, negatively impacting its performance and NAV. Falling rates may result in the fund investing in lower yielding debt instruments, lowering the fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Mortgage and asset-backed securities are affected by interest rates, financial health of issuers/originators, creditworthiness of entities providing credit enhancements and the value of underlying assets. Investing in derivatives is a specialized activity that involves special risks that subject the fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Market or other (e.g., interest rate) environments may adversely affect the liquidity of fund investments, negatively impacting their price.
