The reorganization of Columbia
Acorn SelectSM with and into Columbia Acorn® Fund
closed on July 10, 2020. Therefore, effective immediately the disclosure of the Transfer Agent's contractual agreement to waive a portion of the fees payable by the Fund, which appears as the third paragraph under the heading "Additional Investment
Strategies and Policies — Fee Waiver/Expense Reimbursement Arrangements" in the "More Information About the Fund" section of the prospectus, is hereby superseded and replaced with the following.
The Transfer Agent has contractually agreed to waive a portion
of the fees payable by the Fund such that through April 30, 2022, fees paid by the Fund to the Transfer Agent do not exceed the annual rate of 0.05% of the average daily net assets of Class Inst2 shares of the Fund unless sooner terminated at the
sole discretion of Fund’s Board of Trustees.
The
rest of the section remains unchanged.
Shareholders
should retain this Supplement for future reference.
