Columbia Emerging Markets Fund
(the "Fund")

The section of the Fund's prospectus entitled "Fees and Expenses of the Fund" is modified by deleting the table entitled "Annual Fund Operating Expenses" in its entirety and replacing it with the following:

Operating Expenses Caption [Text] rr_OperatingExpensesCaption

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Fee Waiver or Reimbursement over Assets, Date of Termination rr_FeeWaiverOrReimbursementOverAssetsDateOfTermination 2014-12-31
Expense Example Supplement [Text Block] columbia_SupplementTextBlock02

The section of the Fund's prospectus entitled "Example" is modified by deleting the table in its entirety and replacing it with the following:
