Article XI, Section 4 of the Registrant’s Declaration of Trust provides that the Registrant, out of the Registrant’s assets, shall indemnify every person who is or has been a Trustee, officer, employee or agent of the Registrant and every person who serves at the Registrant’s request as director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise shall be indemnified by the Registrant to the fullest extent permitted by law against all liabilities and against all expenses reasonably incurred or paid by him in connection with any debt, claim, action, demand, suit, proceeding, judgment, decree, liability or obligation of any kind in which he becomes involved as a party or otherwise or is threatened by virtue of his being or having been a Trustee, officer, employee or agent of the Registrant or of another corporation, partnership, joint venture, trust or other enterprise at the request of the Registrant against amounts paid or incurred by him in the compromise or settlement thereof.

No indemnification shall be provided to any person hereunder against any liabilities to the Registrant or its shareholders adjudicated to have been incurred by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of such person’s office.

Article V, Section 1(t) of the Registrant’s Declaration of Trust, and Article IX, Section 3 of the Registrant’s By-Laws, provide that the Registrant’s Trustees are permitted to purchase insurance of any kind, including, without limitation, insurance on behalf of any person who is or was a Trustee, officer, employee or agent of the Trust, or is or was serving at the request of the Trust as a trustee, director, officer, agent or employee of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity or arising out of such person’s status as such.

Item 33. Location of Accounts and Records

All applicable accounts, books and documents required to be maintained by the Registrant by Section 31(a) of the Investment Company Act of 1940 and the Rules promulgated thereunder are in the possession and custody of the Registrant’s custodian, State Street Bank and Trust Company, State Street Financial Center, One Lincoln Street, Boston, MA 02111, and its transfer agent, DST Asset Manager Solutions, Inc., 30 Dan Road, Canton, MA 02021, with the exception of certain corporate documents and portfolio trading documents which are in the possession and custody of the administrator and investment adviser.  Registrant is informed that all applicable accounts, books and documents required to be maintained by registered investment advisers are in the custody and possession of Calvert Research and Management, located at 1825 Connecticut Ave NW, Suite 400, Washington, DC 20009 and Eaton Vance Management, located at Two International Place, Boston, MA 02110.

Item 34.    Management Services

Not applicable

Item 35.    Undertakings

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “1933 Act”), may be permitted to directors, trustees, officers and controlling persons of the Registrant and the principal underwriter pursuant to the provisions described in response to Item 30, or otherwise, the Registrant has been advised that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, 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, trustee, officer, or controlling person of the Registrant and the principal underwriter in connection with the successful defense of any action, suite or proceeding) is asserted against the Registrant by such director, trustee, officer or controlling person or principal underwriter in connection with the shares 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 1933 Act and will be governed by the final adjudication of such issue.
