Morningstar DBRS Takes Credit Rating Actions on 33 U.S. RMBS Transactions

DBRS, Inc. (Morningstar DBRS) reviewed 764 classes from 33 U.S. residential mortgage-backed securities (RMBS) transactions. Of the 33 transactions reviewed, 24 are classified as prime mortgage transactions, eight are classified as mortgage insurance linked note transactions and one is classified as an agency credit-risk transfer transaction. Of the 764 classes reviewed, Morningstar DBRS upgraded its credit ratings on 33 classes and confirmed its credit ratings on 731 classes.

CREDIT RATING RATIONALE/DESCRIPTION

The credit rating upgrades reflect a positive performance trend and an increase in credit support sufficient to withstand stresses at the new credit rating level. 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 March 2025 Update" published on March 26, 2025 (https://dbrs.morningstar.com/research/450604). 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 June 28, 2024 (https://dbrs.morningstar.com/research/435291).

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 credit 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 Morningstar DBRS Criteria: Approach to Environmental, Social, and Governance Factors in Credit Ratings (August 13, 2024) at https://dbrs.morningstar.com/research/437781.

Other methodologies referenced in this transaction 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 below varies among tranches requiring (1) requiring additional seasoning and/or updated performance to substantiate a further upgrade, or (2) actual deal or tranche performance not fully reflected in the projected cashflows/ model output.

The below tranches materially deviate because of additional seasoning and/or updated performance being warranted to substantiate a further upgrade:

-- J.P. Morgan Mortgage Trust 2023-3, Mortgage Pass-Through Certificates, Series 2023-3 , Class B-4
-- J.P. Morgan Mortgage Trust 2023-3, Mortgage Pass-Through Certificates, Series 2023-3 , Class B-5

The below tranches materially deviate because actual deal or tranche performance is not fully reflected in the projected cashflow/model output:

-- Chase Home Lending Mortgage Trust 2024-5, Mortgage Pass-Through Certificates, Series 2024-5, Class B-5

The credit ratings were initiated at the request of the rated entities.

The rated entity or its related entities did participate in the credit rating process for these credit rating actions.
