The examination performed by Ernst & Young LLP identifiedan instance of material noncompliance with the servicing criteria set forth inItem 1122(d)(4)(ix) of Regulation AB applicable to KeyBank during the yearended December 31, 2022. During compliance testing, it was discovered, that notall FlexARM loan mortgagors were offered loan rates within 45-60 days beforethe rate change date, as required per the related pool asset documents. Per therelated note, if the holder fails to offer a loan rate within 45-60 days of anychange date a margin of 2.25% is to be used. Given the notification was notmade to the borrowers, a 3% margin was incorrectly applied.

The following remediation procedures have been initiated byKeyBank: (i) the impacted mortgage loans are currently in the process of beingidentified, (ii) investor contact has been initiated, (iii) corrective actionsare being considered and will be tracked and monitored by senior management,(iv) procedures will be reviewed and revised, if necessary, to include newtracking and action steps to prevent this situation from recurring in thefuture, and (v) training will be provided to the relevant staff members toprevent a recurrence.
