The section entitled "Columbia Small Cap Value Fund II - Performance Information" is modified by deleting the first paragraph of the section and replacing it with the following:

The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The returns shown for Class R shares include the returns of the Fund's Class A shares (without applicable sales charges) for periods prior to January 23, 2006, the date on which Class R shares commenced operations. The returns shown for Class I shares include the returns of the Fund's Class Z shares, which are not offered in this prospectus, for periods prior to September 27, 2010, the date Class I shares commenced operations. The returns shown have not been adjusted to reflect any differences in expenses. If differences in expenses had been reflected, the returns shown for Class R shares would be lower. The Fund's past performance (before or after taxes) is no guarantee of how the Fund will perform in the future.
