DBRS Morningstar Takes Rating Actions on 19 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 193 classes from 19 U.S. residential mortgage-backed securities (RMBS) transactions. The 19 transactions are generally classified as subprime and Alt-A collateral. Of the 193 classes reviewed, DBRS Morningstar upgraded 16 ratings and confirmed 177 ratings.

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

The transaction assumptions consider DBRS Morningstar’s baseline macroeconomic scenarios for rated sovereign economies, available in its commentary “Baseline Macroeconomic Scenarios for Rated Sovereigns: April 23 Update,” published on April 28, 2023 (https://www.dbrsmorningstar.com/research/413218). These baseline macroeconomic scenarios replace DBRS Morningstar’s moderate and adverse Coronavirus Disease (COVID-19) pandemic scenarios, which were first published in April 2020.

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

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 DBRS Morningstar considers ESG factors within the DBRS Morningstar analytical framework can be found in the DBRS Morningstar Criteria: Approach to Environmental, Social, and Governance Risk Factors in Credit Ratings at https://www.dbrsmorningstar.com/research/396929 (May 17, 2022).

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

Other methodologies referenced in these transactions are listed at the end of this press release. These may be found at: https://www.dbrsmorningstar.com/about/methodologies.

The DBRS Morningstar Sovereign group releases baseline macroeconomic scenarios for rated sovereigns. DBRS Morningstar analysis considered impacts consistent with the baseline scenarios as set forth in the following report: https://www.dbrsmorningstar.com/research/384482.

The credit ratings assigned to the classes below materially deviate from the ratings implied by the predictive model. DBRS Morningstar 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 is additional seasoning being warranted to substantiate a further upgrade.
