Performance Information

The section entitled "Columbia LifeGoal® Growth Portfolio - 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. Class R4 shares commenced operations on March 7, 2011; therefore, calendar year performance information for this class is not yet available. The average annual total return table includes the returns of the Fund's Class A shares (without applicable sales charges). Class R4 shares would have annual returns substantially similar to those of Class A shares (without applicable sales charges), because each of the Fund's share classes is invested in the same portfolio of securities, and its returns would differ only to the extent that its expenses differ. The returns shown for Class A shares have not been adjusted to reflect any differences in expenses between Class R4 shares and Class A shares. The returns shown for Class R shares include the returns of the Fund's Class A shares (without applicable sales charges) for the periods prior to January 23, 2006, the date Class R shares commenced operations. The returns shown do not 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.
