ITEM 30. INDEMNIFICATION.

The Registrant is organized as a Delaware statutory trust and is operated pursuant to an Amended and Restated Agreement and Declaration of Trust dated August 22, 2025 (“Declaration of Trust”) that permits the Registrant to indemnify its trustees and officers under certain circumstances. Such indemnification, however, is subject to the limitations imposed by the Securities Act of 1933, as amended (the “1933 Act”), and the Investment Company Act of 1940, as amended (the “1940 Act”). Article IX, Section 2 of the Registrant’s Declaration of Trust provides that officers and trustees of the Trust shall be indemnified by the Trust against liabilities and expenses of defense in proceedings against them by reason of the fact that they each serve as an officer or trustee of the Trust.

Pursuant to Rule 484 under the 1933 Act, the Registrant furnishes the following undertaking: “Insofar as indemnification for liability 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 the Securities 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 the Securities Act and will be governed by the final adjudication of such issue.”

ITEM 31. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER AND SUB-ADVISER

Man Solutions LLC (“Man Solutions”) serves as the investment adviser to the Registrant. Man Solutions is engaged in the investment advisory business. For information as to the business, profession, vocation or employment of a substantial nature in which Man Solutions and its executive officers and directors is or has been, during the last two fiscal years, engaged for his or her own account or in the capacity of director, officer, employee, partner or trustee, reference is made to the information set forth in Man Solutions’ Form ADV (File No. 801-72402), as filed with the SEC and incorporated herein by reference.
