#### Item 29: Number of Holders of Securities
At February 21, 2025:

| Title of Class                    |     | Number of Record Holders |
| Common Shares, par value $0.00001 |     |           181,602,918.80 |

#### Item 30: Indemnification
**Reference is made to Article VIII, Sections 1 through 4, of the Registrant’s Amended and Restated Agreement and Declaration of Trust, which is incorporated by reference herein.

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 Fourth 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.
