OTHER INFORMATION

PART C. OTHER INFORMATION

Item 15. — Indemnification

Article Five of the Bylaws of Registrant provides that 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 Registrant’s Bylaws, which have 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 Covered Person is indemnified under the Bylaws against any liability to Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of the Covered Person’s 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 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 Securities Act of 1933 and, therefore, is unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
