Morningstar DBRS Takes Credit Rating Actions on 27 U.S. RMBS Transactions

DBRS, Inc. (Morningstar DBRS) reviewed 180 classes in 27 U.S. residential mortgage-backed securities (RMBS) transactions. Of the 27 transactions reviewed, 17 are classified as RMBS backed by reperforming mortgages and 10 are classified as legacy RMBS backed by manufactured housing, home equity line of credit, second lien, or scratch and dent mortgage collateral. Of the 180 classes reviewed, Morningstar DBRS upgraded 70 credit ratings and confirmed 110 credit ratings.

The credit rating upgrades reflect positive performance trends and increases in credit support sufficient to withstand stresses at their new credit rating levels. The credit rating confirmations reflect asset-performance and credit-support levels that are consistent with the current credit ratings.

The transaction assumptions consider Morningstar DBRS’ baseline macroeconomic scenarios for rated sovereign economies, available in its commentary “Baseline Macroeconomic Scenarios for Rated Sovereigns: December 2023 Update,” published on December 19, 2023 (https://dbrs.morningstar.com/research/425506). These baseline macroeconomic scenarios replace Morningstar DBRS’ moderate and adverse coronavirus pandemic scenarios, which were first published in April 2020.

The credit rating actions are the result of Morningstar DBRS’ application of its “U.S. RMBS Surveillance Methodology,” published on March 3, 2023.

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.

A description of how Morningstar DBRS considers ESG factors within the Morningstar DBRS analytical framework can be found in the DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings (January 23, 2024) at https://dbrs.morningstar.com/research/427030.

Notes:
The principal methodology applicable to the credit ratings is the U.S. RMBS Surveillance Methodology (March 3, 2023), https://dbrs.morningstar.com/research/410498.

Other methodologies referenced in these transactions are listed at the end of this press release.

The credit ratings assigned to the classes below materially deviate from the credit ratings implied by the predictive model. Morningstar DBRS typically expects there to be a substantial likelihood that a reasonable investor or other user of the credit ratings would consider a three-notch or more deviation from the credit rating stresses implied by the predictive model to be a significant factor in evaluating the credit ratings. The rationale for the material deviations of the below tranches is additional seasoning and/or updated performance to be measured against a sustainable upgrade loan-level cash flow stress.
