To find out more, call [800.426.3750]( or visit [columbiathreadneedle.com](. Carefully consider the fund’s investment objectives, risk factors, charges and expenses before investing. This and other information can be found in the fund’s prospectus, which may be obtained by calling 800.426.3750 or by visiting the fund’s website www.columbiathreadneedleus.com/ to view or download a prospectus. Read the prospectus carefully before investing. Investing involves risk, including possible loss of principal. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. 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. Fixed-income securities present issuer default risk. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. 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. Floating rate loans typically present greater risk than other fixed-income investments as they are generally subject to legal or contractual resale restrictions, may trade less frequently and experience value impairments during liquidation. 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. Foreign investments subject the fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. Risks are enhanced for emerging market and sovereign debt issuers. 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. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. Diversification does not assure a profit or protect against loss. Morningstar ratings for the overall, three-, five- and ten-year periods for the A-share are 4 stars, 3 stars, 3 stars, and 4 stars and for the Inst-share are 4 stars, 3 stars, 3 stars, and 4 stars among 295, 295, 253 and 137 Nontraditional Bond funds, respectively, and are based on a Morningstar Risk-Adjusted Return measure. Morningstar calculates a Morningstar Rating™ used to rank the fund against other funds in the same category. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly excess performance, without any adjustments for loads (front-end, deferred or redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages). The Overall Morningstar RatingTM for a fund is derived from a weighted average of the performance figures associated with its three-, five- and 10-year (if applicable) Morningstar Rating metrics. Load-waived A share star ratings do not include any front-end sales load and are intended for those investors who have access to such purchase terms (e.g., plan participants of a defined contribution plan). Not all A share mutual funds for which Morningstar calculates a load-waived A share star rating may actually waive their front-end sales load. Therefore, Morningstar strongly encourages investors to contact their investment professional to determine whether they are eligible to purchase A shares without paying the front load. ©2023 Morningstar, Inc.
