Supplement to the Prospectuses dated January 1, 2011

The legacy Columbia Funds and legacy RiverSource Funds (each a “Fund”), for which Columbia Management Investment Advisers, LLC (“CMIA”) serves as investment manager and sponsor, include various legacy groups of Funds organized at different times by different organizations. As a result, various features of the Funds, including their fees and expenses do not currently reflect a common overall design.

In September 2010, in connection with various initiatives to integrate the Funds into a single Fund family with greater uniformity, the Boards of Directors/Trustees (each a “Board”) of the Funds each approved amended investment management services agreements (“IMSA”s) and administrative services agreements with CMIA. These agreements reflect standardized fee schedules for similar Funds, based on a consistent pricing model. The Boards also approved amended transfer agency agreements with a uniform fee schedule. In connection with the Boards’ approval of various proposals to achieve a consistent pricing model, the Boards and CMIA agreed to an annual process by which contractual expense limitations for Funds with annual operating expenses that exceed the median expense ratios of their respective peer groups (as determined annually by an independent third-party data provider) are generally set at or below such median expense ratio. These commitments may help mitigate the impact of any fee changes resulting from the adoption of standardized fee schedules. The estimated proposed expense caps shown in the following table reflect peer group median expense ratios as of early 2010, which are likely to change year over year.

While these changes are expected to reduce the overall fees and expenses of the Funds in the aggregate, certain Funds are expected to realize an increase in fees under their proposed IMSA and/or total annual operating expenses. Any proposed amended IMSA that could result in higher fees (each an “IMSA Proposal”) is subject to approval by Fund shareholders at a meeting expected to be held in the first half of 2011. More information about each IMSA Proposal will be included in proxy materials that are currently anticipated to be distributed to shareholders in early 2011.

If approved by Fund shareholders, the IMSA Proposals, as well as IMSAs not subject to Fund shareholder approval and new administrative services agreements, are expected to be effective in the second quarter of 2011.

The information in the chart below shows the estimated impact of the changes discussed above on each Fund’s Class A shares based on the Fund’s net assets as of July 31, 2010. Expenses for other share classes will differ to the extent of differences in transfer agency and/or distribution and service fees, and actual fees and expenses will vary based upon the size of the Fund and other factors, and may be higher or lower than the estimates shown below.
