| Amendment Description | The Registrant is filing this Amendment No. 1 on Form 10-K/A (the “Amendment”) to its Form 10-K for the year ended September 30, 2024, as originally filed with the U.S. Securities and Exchange Commission on November 25, 2024 (the “Original Filing”), for the sole purpose of including Exhibit 97.1. In accordance with Rule 12b-15 and Rule 13a-14 promulgated under the Securities Exchange Act of 1934, as amended, this Amendment also includes new certifications by the Principal Executive Officer and Principal Financial Officer of the Registrant’s Sponsor on behalf of the Registrant dated as of the date of this filing. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment, certifications pursuant to Section 906 of the Sarbanes Oxley Act of 2002 have been omitted. Except as described above, no other amendments are being made to the Original Filing. This Amendment does not supersede, modify or update any other items or disclosures found in the Original Filing. In addition, this Amendment does not reflect any information, events or transactions occurring after the reporting period of the Original Filing and does not supersede, modify or update those disclosures affected by subsequent events. As a result, information included in the report continues to speak as of the date of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original Filing together with the Registrant’s other filings with the SEC. Item 15. Exhibits, as amended, is included in this Amendment. This Amendment consists solely of the preceding cover page, this explanatory note, Item 15. Exhibits, the signature page and Exhibits 31.1, 31.2 and 97.1. | ||
