Item 6.04 Failure to Make a Required Distribution.

The Certificate Administrator made distributions to the Certificateholders on the August 17, 2023 Distribution Date. On September 27, 2023, the Certificate Administrator was notified by the Master Servicer that certain non-recoverable advances 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.

In addition, the amounts of principal and interest distributed to certain classes of certificates and the beginning and ending certificate balances for certain classes of certificates shown on the registrant’s Monthly Distribution Report filed as Exhibit 99.1 to the Asset Backed Issuer Distribution Reports on Form 10-D for the September 2023 distribution period have also been corrected to reflect the adjustments described above. The revised Monthly Distribution Reports are included with the registrant’s Form 10-D/A’s for the August and September distribution periods. All corrected payments to the impacted Certificateholders were made on October 2, 2023.
