Accordingly, the average annual total returns tables in the “Past Performance” sections of the Fund’s prospectuses are hereby replaced with the following and should be retained with the current prospectus for the Fund for future reference.

Fund performance information prior to March 7, 2011 represents that of the Fund as a series of RiverSource International Series, Inc., a Minnesota corporation. The Fund was reorganized into a series of Columbia Funds Series Trust II, a Massachusetts business trust, on that date.

[1] The returns shown are for Class R5 shares. Class Z shares would have substantially similar annual returns as Class R5 shares because the classes of shares invest in the same portfolio of securities and would differ only to the extent that the classes do not have the same expenses. Class R5 share returns have not been adjusted to reflect differences in class-related expenses. If differences in class-related expenses were reflected (i.e., if expenses of Class Z shares were reflected in the Class R5 share returns), the returns shown for Class R5 shares for all periods would be higher.

[2] On September 30, 2011, the MSCI All Country Asia Pacific Ex-Japan Index (Net) replaced the MSCI All Country Asia Pacific Ex-Japan Index (Gross) as the Fund's primary benchmark. The Fund's investment manager made this recommendation to the Fund's Board because the investment manager believes that the Net version better reflects how dividends paid to the Fund on foreign securities generally are treated for tax purposes and, therefore, provides a more appropriate basis for comparing the Fund's performance. Information on both versions of the index will be included for a one-year transition period. Thereafter, only the Net version will be included.
