Item 6.04 Failure to Make a Required Distribution.

The Certificate Administrator made distributions to the Certificateholders on the June 17, 2022 Distribution Date.  On June 22, 2022, the Certificate Administrator was notified that the Master Servicer revised the June distribution amounts because the payoff on the Southpark Mall Mortgage Loan (Loan Number 5 on Annex A-1 of the prospectus supplement of the registrant relating to the issuing entity filed on June 26, 2012 pursuant to Rule 424(b)(5)) had originally been reported in error.  This resulted in an overpayment of principal to the Class D Certificateholders in the amount of $24,116,444.35 and an overpayment of principal to the Class E Certificateholders in the amount of $30,683,539.57.  Claims have been submitted to the Class D and Class E Certificateholders for the overpaid amounts and when those funds are received, they will be returned to the Master Servicer.
