Item 29. Control Persons. None.

Item 30. Indemnification.

Reference is made to Article VIII of the Registrant’s Agreement and Declaration of Trust. The application of these provisions is limited by the following undertaking set forth in the rules promulgated by the Securities and Exchange Commission:

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in such 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 trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, 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 such Act and will be governed by the final adjudication of such issue. The Registrant may maintain a standard mutual fund and investment advisory professional and directors and officers’ liability policy. The policy, if maintained, would provide coverage to the Registrant, its Trustees and officers, and could cover its advisers, among others. Coverage under the policy would include losses by reason of any act, error, omission, misstatement, misleading statement, neglect or breach of duty.
