Item 29 Persons Controlled by or Under Common Control with the Fund:

None

Item 30. Indemnification

Indemnification is provided to Officers and Trustees of the Registrant pursuant to the Registrant's By-Laws, as amended. This includes indemnification against: (a) any liabilities or expenses incurred in connection with the defense or disposition of any action, suit or proceeding in which an Officer or Trustee may be or may have been involved; and (b) any liabilities and expenses incurred by an Officer or Trustee as a result of having provided personally identifiable information to a regulator or counterparty by or with whom the Registrant (or its series, as applicable) is regulated or engages in business to satisfy a legal or procedural requirement of such regulator or counterparty.

The Investment Advisory Contract, and Sub-advisory Agreement as applicable, (collectively, “Advisory Contracts”) between the Registrant and the investment adviser, and sub-adviser as applicable, (collectively, “Advisers”) of its series, provide that, in the absence of willful misfeasance, bad faith, gross negligence, or reckless disregard of the obligations or duties under the Advisory Contracts on the part of the Advisers, Advisers shall not be liable to the Registrant or to any shareholder for any act or omission in the course of or connected in any way with rendering services or for any losses that may be sustained in the purchase, holding, or sale of any security.

The Registrant’s distribution contract contains provisions limiting the liability, and providing for indemnification, of the Officers and Trustees under certain circumstances.

Registrant's Trustees and Officers are covered by an Investment Trust Errors and Omissions Policy.

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 By-Laws, as amended, or otherwise, the Registrant is aware that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act 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 Trustees), Officers, or controlling persons of the Registrant in connection with the successful defense of any act, suit, or proceeding) is asserted by such Trustees, Officers, or controlling persons 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 Act and will be governed by the final adjudication of such issues.

Insofar as indemnification for liabilities may be permitted pursuant to Section 17 of the Investment Company Act of 1940 for Trustees, Officers, and controlling persons of the Registrant by the Registrant pursuant to the By-Laws, as amended, or otherwise, the Registrant is aware of the position of the Securities and Exchange Commission as set forth in Investment Company Act Release No. IC-11330. Therefore, the Registrant undertakes that in addition to complying with the applicable provisions of the By-Laws, as amended, or otherwise, in the absence of a final decision on the merits by a court or other body before which the proceeding was brought, that an indemnification payment will not be made unless in the absence of such a decision, a reasonable determination based upon factual review has been made (i) by a majority vote of a quorum of non-party Trustees who are not interested persons of the Registrant or (ii) by independent legal counsel in a written opinion that the indemnitee was not liable for an act of willful misfeasance, bad faith, gross negligence, or reckless disregard of duties. The Registrant further undertakes that advancement of expenses incurred in the defense of a proceeding (upon undertaking for repayment unless it is ultimately determined that indemnification is appropriate) against an Officer, Trustee or controlling person of the Registrant will not be made absent the fulfillment of at least one of the following conditions: (i) the indemnitee provides security for his undertaking; (ii) the Registrant is insured against losses arising by reason of any lawful advances; or (iii) a majority of a quorum of disinterested non-party Trustees or independent legal counsel in a written opinion makes a factual determination that there is reason to believe the indemnitee will be entitled to indemnification.
