Explanatory Note:

This Form 10-D/A amends the registrant's Asset Backed Issuer Distribution Report on Form 10-D filed by the Registrant on August 31, 2023 (SEC Accession No. 0001888524-23-012192) (the "Original 10-D"). The purpose of this amendment is to revise information in the Monthly Distribution Report filed as Exhibit 99.1 to the Original 10-D relating to amounts payable to the Certificateholders. The payment revisions were made to account for certain non-recoverable advances which were not withheld from principal collections for the August distribution period in error. This resulted in an additional interest payment to the Class A-S Certificateholders in an amount equal to $256,135.00, an additional interest payment to the Class B Certificateholders in an amount equal to $302,282.33, an additional interest payment to the Class C Certificateholders in an amount equal to $151,143.24 and an additional interest payment to the Class D Certificateholders in an amount equal to $233,123.56. This also resulted in an overpayment of principal to the Class A-4 Certificateholders in an amount equal to $458,578.21 and an overpayment of principal to the Class A-SB Certificateholders in an amount equal to $484,105.91. All corrected payments to the impacted Certificateholders were made on October 2, 2023.
