                                     *****

Changes to Class A and Class Z shares of each of the Funds and features of
Class R5 shares of Columbia Acorn International, as described in the supplement
to the prospectus(es) and Statement of Additional Information of each of the
Funds, dated and filed October 1, 2012 pursuant to Rule 497(e) of the
Securities Act of 1933, Accession No. 0001193125-12-410394, are incorporated by
reference.

Certain features of Class A and Class Z shares of each of the Funds and
features of Class R5 shares of Columbia Acorn International were changed, as
described below:

1. Changes to Class R5 - Re-opening; Eligibility. Effective November 8, 2012,
   Class R5 shares of Columbia Acorn International are available for purchase
   by (i) registered investment advisers that clear Fund share transactions for
   their client or customer accounts through designated mutual fund trading
   platforms that have been granted specific written authorization from the
   Funds' transfer agent with respect to Class R5 eligibility apart from
   selling, servicing or similar agreements and (ii) omnibus retirement plans.
   Existing shareholders who do not satisfy the new eligibility requirements
   for investment in Class R5 shares may not establish new Class R5 accounts,
   but may continue to make additional purchases of Class R5 shares in accounts
   opened and funded prior to November 8, 2012. In addition, investment
   advisory programs and similar programs that opened a Class R5 account as of
   May 1, 2010, and continuously hold Class R5 shares in such account after
   such date, may generally not only continue to make additional purchases of
   Class R5 shares but also open new Class R5 accounts and add new shareholders
   in the program. Prior to November 8, 2012, Class R5 shares were closed to
   new investors and new accounts, subject to certain exceptions.

2. Changes to Class Z - Partial Closing.

    A. Omnibus Retirement Plans. Effective March 29, 2013, omnibus retirement
       plans are not permitted to establish new Class Z accounts, subject to
       the following exceptions. Omnibus retirement plans that opened and
       funded a Class Z account with the Fund as of the close of business on
       March 28, 2013, and continuously hold Class Z shares in such account
       after March 28, 2013, may continue to make additional purchases of Class
       Z shares, open new Class Z accounts and add new participants. In
       addition, an omnibus retirement plan may, in the discretion of the
       Funds' distributor, open new Class Z accounts for a Fund after March 28,
       2013 if the plan's sponsor or an affiliated sponsor opened and funded a
       Class Z account for another omnibus retirement plan as of the close of
       business on March 28, 2013. If an omnibus retirement plan invested in
       Class Z shares changes recordkeepers after March 28, 2013, any new
       accounts established for that plan may not be established in Class Z
       shares but such a plan may establish new accounts in a different share
       class for which the plan is eligible.

    B. Selling Agents that Clear through Certain Platforms. Effective March 29,
       2013, accounts of selling agents (other than omnibus retirement plans,
       discussed above) that clear Fund share transactions for their client or
       customer accounts through designated mutual fund trading platforms that
       have been given specific written notice from the Fund's transfer agent
       of the termination of their eligibility for new purchases of Class Z
       shares will not be permitted to establish new Class Z accounts or make
       additional purchases of Class Z shares for existing accounts (other than
       through reinvestment of distributions).

    C. Other Existing Class Z Shareholders. Existing holders of Class Z shares
       (other than those described in the immediately preceding paragraph) may
       continue to maintain Class Z accounts and make additional purchases of
       Class Z shares (including through reinvestment of distributions).

3. Exchangeability. Shareholders may exchange shares of one share class of a
   Fund for shares of another share class of the Fund or another fund managed
   by Columbia Wanger Asset Management, LLC or its affiliates, subject to
   eligibility. Before making such an exchange, you should consider the fees
   and expenses of each share class.

4. Front-End Sales Charge Waivers for Class A Shares. Effective November 8,
   2012, the Funds' distributor may waive front-end sales charges on
   (i) purchases (including exchanges) of Class A shares in accounts of selling
   agents that have entered into agreements with the Funds' distributor to
   offer Fund shares to self-directed investment brokerage accounts that may or
   may not charge a transaction fee to customers and (ii) exchanges of Class Z
   shares of a Fund for Class A shares of the Fund.

                                     *****
