The credit rating confirmations reflect asset performance and credit-support levels that are consistent with the current credit ratings. The credit rating upgrades reflect a positive performance trend and/or an increase in credit support sufficient to withstand stresses at the new credit rating level.

Morningstar DBRS' credit rating actions are based on the following analytical considerations:

-- Key performance measures as reflected in month-over-month changes in vacancy and delinquency, quarterly analysis of the actual expenses, credit enhancement increases since deal inception, and bond paydown factors.

Morningstar DBRS' credit ratings on the applicable classes address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents. Where applicable, a description of these financial obligations can be found in the transactions' respective press releases at issuance.

Morningstar DBRS' long-term credit ratings provide opinions on risk of default. Morningstar DBRS considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued. The Morningstar DBRS short-term debt rating scale provides an opinion on the risk that an issuer will not meet its short-term financial obligations in a timely manner.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE CONSIDERATIONS
There were no Environmental/Social/Governance factors that had a significant or relevant effect on the credit analysis.
