Morningstar DBRS Takes Credit Rating Actions on Nine U.S. RMBS Transactions
RMBSDBRS, Inc. (Morningstar DBRS) reviewed 268 classes from nine U.S. residential mortgage-backed securities (RMBS) transactions. The nine transactions reviewed are classified as prime jumbo transactions. Of the 268 classes reviewed, Morningstar DBRS upgraded its credit ratings on six classes and confirmed its credit ratings on 262 classes.
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 September 2024 Update" published on September 25, 2024 (https://dbrs.morningstar.com/research/439965). 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.
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.

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 having (1) risk(s) not fully reflected in the quantitative model output, (2) requiring additional seasoning and/or updated performance to substantiate a further upgrade, or (3) a dependency on another tranche's credit rating (i.e., interest-only (IO) and exchangeable tranches).
The below tranches materially deviate because of risk(s) not fully reflected in the quantitative model output:
-- CIM Trust 2018-INV1, Mortgage Pass-Through Certificates, Series 2018-INV1, Class B-4
-- CIM Trust 2018-INV1, Mortgage Pass-Through Certificates, Series 2018-INV1, Class B-5

-- Galton Funding Mortgage Trust 2018-2, Mortgage Pass-Through Certificates, Series 2018-2, Class B5
The below tranches materially deviate because of additional seasoning and/or updated performance being warranted to substantiate a further upgrade:
-- TIAA Bank Mortgage Loan Trust 2018-3, Mortgage Pass-Through Certificates, Series 2018-3, Class B-4
The below tranches materially deviate because of a dependency on another tranche's credit rating such as (IO) or exchangeable tranches:
-- CIM Trust 2020-J2, Mortgage Pass-Through Certificates, Series 2020-J2, Class B-IO2
