EXPLANATORY NOTE

This Post-Effective Amendment is being filed solely to file as an exhibit the final opinion of Ropes & Gray LLP supporting the tax consequences of the reorganizations (Exhibit 12 to Item 16) of this Registration Statement on Form N-14 (the “Registration Statement”) and does not modify any other part of the Registrant’s Registration Statement. This Post-Effective Amendment will become effective automatically upon filing with the Commission pursuant to Rule 462(d) under the Securities Act of 1933, as amended (the “Securities Act”).

The joint Proxy Statement/Prospectus and Statement of Additional Information, each dated as of May 13, 2025 and as filed on May 13, 2025 pursuant to Rule 424(b)(3) of the Securities Act (File No. 333-286391), is incorporated herein by reference.

PART C

OTHER INFORMATION

Item 15. Indemnification

Reference is made to Article VIII, Sections 1 through 5, of the Registrant’s Amended and Restated Agreement and Declaration of Trust.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted to trustees, officers and controlling persons of the Registrant by the Registrant pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, its Amended and Restated Bylaws 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 Securities 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 the successful defense of any action, suit or proceeding) is asserted by such trustees, officers or controlling persons 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.
