Effective immediately, the information under the subsection "Other Roles and Relationships of Ameriprise Financial and Its Affiliates - Certain Conflicts of Interest" in the "Investment Management and Other Services" section of the SAI for the above mentioned Funds is hereby revised to include the following:

Actual or Potential Conflicts of Interest Related to Affiliated Indexes

Columbia Management and its affiliates may develop, own and operate stock market and other indexes (each, an Affiliated Index) based on investment and trading strategies developed by Columbia Management and/or its affiliates (Affiliated Index Strategies). Some of the ETFs for which Columbia Management act as investment adviser (the Affiliated Index ETFs) seek to track the performance of the Affiliated Indexes. Columbia Management and/or its affiliates may, from time to time, manage other funds or accounts that invest in these Affiliated Index ETFs. In the future, Columbia Management and/or its affiliates may manage client accounts that track the same Affiliated Indexes used by the Affiliated Index ETFs or which are based on the same, or substantially similar, Affiliated Index Strategies that are used in the operation of the Affiliated Indexes and the Affiliated Index ETFs. The operation of the Affiliated Indexes, the Affiliated Index ETFs and other accounts manage in this manner may give rise to potential conflicts of interest.

For example, any accounts managed by Columbia Management and/or its affiliates that seek to track the same Affiliated Indexes may engage in purchases and sales of securities at different times. These differences may result in the certain accounts having more favorable performance relative to that of the Affiliated Index or other accounts that seek to track the Affiliated Index. Other potential conflicts include (i) the potential for unauthorized access to Affiliated Index information, allowing Affiliated Index changes that benefit Columbia Management and/or its affiliates or other accounts managed by Columbia Management and/or its affiliates and not the clients in the accounts seeking to track the Affiliated Index, and (ii) the manipulation of Affiliated Index pricing to present the performance of accounts seeking to track the Affiliated Index, or the firm’s tracking ability, in a preferential light.

Columbia Management has adopted policies and procedures that are designed to address potential conflicts that may arise in connection with the operation of the Affiliated Indexes, the Affiliated Index ETFs and other accounts. 

To the extent it is intended that an account managed by Columbia Management and/or its affiliates seeks to track an Affiliated Index, the account may not match (performance or holdings), and may vary substantially from, such index for any period of time. An account that seeks to track an index may purchase, hold and sell securities at times when another client would not do so. Columbia Management and its affiliates do not guarantee that any tracking error

targets will be achieved. Accounts managed by Columbia Management and/or its affiliates that seek to track an index may be negatively impacted by errors in the index, either as a result of calculation errors, inaccurate data sources or otherwise. Columbia Management and its affiliates do not guarantee the timeliness, accuracy and/or completeness of an index and are not responsible for errors, omissions or interruptions in the index (including when Columbia Management or an affiliate acts as the index provider) or the calculation thereof (including when Columbia Management or an affiliate acts as the calculation agent).

Columbia Management and its affiliates are not obligated to license the Affiliated Indexes to clients or other third-parties.

The rest of the section remains the same.

Shareholders should retain this Supplement for future reference.
