The Certificate Administrator made distributions to the Certificateholders on the August 17, 2020 and September 17, 2020 Distribution Dates. On September 24, 2020, the Certificate Administrator was notified that the Master Servicer revised the September distribution amounts to include additional ASER related cash shortfalls. This resulted in an overpayment to the Class NR-RR Certificateholders in the amount of $69,950.10. The Certificateholders disputed the servicer’s reporting, and the claim was discarded. On November 3, 2020, the Certificate Administrator was advised by the Master Servicer that ASER amounts reported were incorrect for the August 17, 2020 and September 17, 2020 Distribution Dates which resulted in incorrect interest payments being made to the Class NR-RR Certificateholders.  This resulted in an overpayment to Class NR-RR Certificateholders of $69,950.10 for the August 17, 2020 Distribution Date and an overpayment to Class NR-RR Certificateholders of $38,422.94 for the September 17, 2020 Distribution Date. A claim has been submitted to the Class NR-RR Certificateholders for the overpaid amounts and when those funds have been received, they will  be returned to the Master Servicer.
