(1)	Debt Service Coverage Ratios are updated periodically as new NOI figures become available from borrowers on an asset level. In all cases the most current DSCR provided by the Servicer is used. To the extent that no DSCR is provided by the Servicer, information from the offering document is
	used. The debt service coverage ratio information was provided to the Certificate Administrator by the Master Servicer and the Certificate Administrator has not independently confirmed the accuracy of such information.
(2)	Anticipated Remaining Term and WAM are each calculated based upon the term from the current month to the earlier of the Anticipated Repayment Date, if applicable, and the Maturity Date.
(3)	Data in this table was calculated by allocating pro-rata the current loan information to the properties based upon the Cut Off Date Balance of each property as disclosed in the offering document. The Scheduled Balance Totals reflect the aggregate balances of all pooled loans as reported in the
	CREFC Loan Periodic Update File. To the extent that the Scheduled Balance Total figure for the "State" and "Property" stratification tables is not equal to the sum of the scheduled balance figures for each state or property, the difference is explained by loans that have been modified into a split
	loan structure. The "State" and "Property" stratification tables do not include the balance of the subordinate note (sometimes called the B-piece or a "hope note") of a loan that has been modified into a split-loan structure.
