RATINGS RATIONALE
Today’s rating actions reflect the recent performance as well as Moody’s updated loss expectations on the underlying pools. The rating upgrades are a result of the improving performance of the related pools, and/or an increase in credit enhancement available to the bonds.
Principal Methodologies
The principal methodology used in these ratings was “US RMBS Surveillance Methodology” published in July 2022 and available at https://ratings.moodys.com/api/rmc-documents/390485. Alternatively, please see the Rating Methodologies page on https://ratings.moodys.com for a copy of this methodology.
In addition, Moody’s publishes a weekly summary of structured finance credit ratings and methodologies, available to all registered users of our website, www.moodys.com/SFQuickCheck.
Factors that would lead to an upgrade or downgrade of the ratings:
Up
Levels of credit protection that are higher than necessary to protect investors against current expectations of loss could drive the ratings of the subordinate bonds up. Losses could decline from Moody’s original expectations as a result of a lower number of obligor defaults or appreciation in the value of the mortgaged property securing an obligor’s promise of payment. Transaction performance also depends greatly on the US macro economy and housing market.
Down
Levels of credit protection that are insufficient to protect investors against current expectations of loss could drive the ratings down. Losses could rise above Moody’s expectations as a result of a higher number of obligor defaults or deterioration in the value of the mortgaged property securing an obligor’s promise of payment. Transaction performance also depends greatly on the US macro economy and housing market. Other reasons for worse-than-expected performance include poor servicing, error on the part of transaction parties, inadequate transaction governance and fraud.
Finally, performance of RMBS continues to remain highly dependent on servicer procedures. Any change resulting from servicing transfers or other policy or regulatory change can impact the performance of these transactions. In addition, improvements in reporting formats and data availability across deals and trustees may provide better insight into certain performance metrics such as the level of collateral modifications.

For further specification of Moody’s key rating assumptions and sensitivity analysis, see the sections Methodology Assumptions and Sensitivity to Assumptions in the disclosure form. Moody’s Rating Symbols and Definitions can be found on https://ratings.moodys.com/rating-definitions.
The analysis includes an assessment of collateral characteristics and performance to determine the expected collateral loss or a range of expected collateral losses or cash flows to the rated instruments. As a second step, Moody’s estimates expected collateral losses or cash flows using a quantitative tool that takes into account credit enhancement, loss allocation and other structural features, to derive the expected loss for each rated instrument.
Moody’s quantitative analysis entails an evaluation of scenarios that stress factors contributing to sensitivity of ratings and take into account the likelihood of severe collateral losses or impaired cash flows. Moody’s weights the impact on the rated instruments based on its assumptions of the likelihood of the events in such scenarios occurring.
For ratings issued on a program, series, category/class of debt or security this announcement provides certain regulatory disclosures in relation to each rating of a subsequently issued bond or note of the same series, category/class of debt, security or pursuant to a program for which the ratings are derived exclusively from existing ratings in accordance with Moody’s rating practices. For ratings issued on a support provider, this announcement provides certain regulatory disclosures in relation to the credit rating action on the support provider and in relation to each particular credit rating action for securities that derive their credit ratings from the support provider’s credit rating. For provisional ratings, this announcement provides certain regulatory disclosures in relation to the provisional rating assigned, and in relation to a definitive rating that may be assigned subsequent to the final issuance of the debt, in each case where the transaction structure and terms have not changed prior to the assignment of the definitive rating in a manner that would have affected the rating.
