DBRS Morningstar Takes Rating Actions on 25 U.S. RMBS Transactions
RMBSDBRS, Inc. (DBRS Morningstar) reviewed 308 classes from 25 U.S. residential mortgage-backed securities (RMBS) transactions. The 25 transactions are generally classified as subprime and Alt-A collateral. Of the 308 classes reviewed, DBRS Morningstar upgraded 33 ratings and confirmed 275 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: June 2023 Update,” published on June 30, 2023 (https://www.dbrsmorningstar.com/research/416703). 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, 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 (July 4, 2023) https://www.dbrsmorningstar.com/research/416784.
Notes:
All figures are in U.S. dollars unless otherwise noted.
The principal methodology applicable to the credit ratings is U.S. RMBS Surveillance Methodology (March 3, 2023; https://www.dbrsmorningstar.com/research/410498/u.s.-rmbs-surveillance-methodology).
Other methodologies referenced in this transaction are listed at the end of this press release.
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 classes below materially deviates from the credit 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 stress(es) implied by the predictive model to be a significant factor in evaluating the credit ratings. The rationale for the material deviations is the additional seasoning and/or updated performance to be measured against a sustainable upgrade loan-level cash flow stress, small loan count, and dependence on a counterparty's rating.

-- J.P. Morgan Mortgage Trust 2005-A3, Mortgage Pass-Through Certificates, Series 2005-A3, Class 5-A-1
