Item 29. Persons Controlled by or Under Common Control with the Registrant

Columbia Management Investment Advisers, LLC (the investment manager or Columbia Management), as sponsor of the Columbia funds, may make initial capital investments in Columbia funds (seed accounts). Columbia Management also serves as investment manager of certain Columbia funds-of-funds that invest primarily in shares of affiliated funds (the underlying funds). Columbia Management does not make initial capital investments or invest in underlying funds for the purpose of exercising control. However, since these ownership interests may be significant, in excess of 25%, such that Columbia Management may be deemed to control certain Columbia funds, procedures have been put in place to assure that public shareholders determine the outcome of all actions taken at shareholder meetings. Specifically, Columbia Management (which votes proxies for the seed accounts) and the Boards of Trustees of the affiliated funds-of-funds (which votes proxies for the affiliated funds-of-funds) vote on each proposal in the same proportion as the vote of the direct public shareholders vote; provided, however, that if there are no direct public shareholders of an underlying fund or if direct public shareholders represent only a minority interest in an underlying fund, the Fund may cast votes in accordance with instructions from the independent members of the Board.

Item 30. Indemnification

Article Ten of the Bylaws of the Registrant provides that the Registrant shall indemnify each of its trustees and officers (including persons who serve at Registrant's request as directors, officers or trustees of another organization in which Registrant has any interest as a shareholder, creditor or otherwise) who are not employees or officers of any investment adviser to Registrant or any affiliated person thereof and its chief compliance officer, regardless of whether such person is an employee or officer of any investment adviser to Registrant or any affiliated person thereof, and each of its other trustees and officers (including persons who serve at Registrant's request as directors, officers or trustees of another organization in which Registrant has any interest as a shareholder, creditor or otherwise) (i.e., those who are employees or officers of any investment adviser to Registrant or any affiliated person thereof) (Covered Persons), to the fullest extent authorized by applicable law against all liabilities and expenses in connection with the defense or disposition of any proceeding in which such Covered Person may be or may have been involved or with which such Covered Person may be or may have been threatened, while in office or thereafter, by reason of any alleged act or omission as a trustee or officer or by reason of his or her being or having been such a Covered Person, all as more fully set forth in the Bylaws, which are filed as an exhibit to the registration statement. The Registrant has also agreed in an indemnification agreement to indemnify to the fullest extent authorized by applicable law against all liabilities and expenses incurred in connection with the defense or disposition any proceeding in which a trustee may be or may have been threatened by reason of any alleged act or omission as a trustee or by reason of being or having been a trustee, except with respect to any matter as to which the trustee shall have been finally adjudicated not to have acted in good faith in the reasonable belief that such trustee’s action was in the best interests of the Registrant, all as more fully set forth in the indemnification agreement with each trustee, a form of which has been filed as an exhibit to this registration statement.

Section 17(h) of the Investment Company Act of 1940 (1940 Act) provides that no instrument pursuant to which Registrant is organized or administered shall contain any provision which protects or purports to protect any trustee or officer of Registrant against any liability to Registrant or its shareholders to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.

In accordance with Section 17(h) of the 1940 Act, no trustee or officer is indemnified under the Bylaws and, in the case of a trustee, the indemnification agreement against any liability by reason of willful misfeasance, bad faith, negligence or reckless disregard of the duties involved in the conduct of his or her office.

Pursuant to the Distribution Agreement, Columbia Management Investment Distributors, Inc. agrees to indemnify the Registrant, its officers and trustees against claims, demands, liabilities and expenses under specified circumstances, all as more fully set forth in the Registrant’s Distribution Agreement, which has been filed as an exhibit to the registration statement.

The Registrant may be party to other contracts that include indemnification provisions for the benefit of the Registrant’s trustees and officers.

The trustees and officers of the Registrant and the personnel of the Registrant’s investment adviser and principal underwriter are insured under an errors and omissions liability insurance policy. Registrant’s investment adviser, Columbia Management Investment Advisers, LLC, maintains investment advisory professional liability insurance to insure it, for the benefit of Registrant and its non-interested trustees, against loss arising out of any effort, omission, or breach of any duty owed to Registrant or any series of Registrant by Columbia Management Investment Advisers, LLC.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the 1933 Act) may be permitted to trustees, officers and controlling persons of the Registrant by the Registrant pursuant to the Registrant’s organizational instruments or otherwise, the Registrant is aware that in the opinion of the Securities and Exchange Commission (SEC), such indemnification is against public policy as expressed in the 1933 Act and, therefore, is unenforceable.
