New York, May 17, 2022 -- Moody's Investors Service, ("Moody's") has downgraded the rating of Cl. A-1 from Credit Suisse First Boston Mortgage Securities Corp. Series 2003-5, which is backed by subprime mortgage loans.
Please click on this link https://www.moodys.com/viewresearchdoc.aspx?docid=PBS_ARFTL466051 for the List of Affected Credit Ratings. This list is an integral part of this Press Release and identifies each affected issuer.
Complete rating actions are as follows:
Issuer: Credit Suisse First Boston Mortgage Securities Corp. Series 2003-5
Cl. A-1, Downgraded to A1 (sf); previously on Mar 23, 2018 Downgraded to Aa3 (sf)
RATINGS RATIONALE
Today's rating action is driven by the fact that the collateral pools backing the transaction has decreased to an effective number below the threshold established in the US RMBS Surveillance Methodology. Moody's does not maintain ratings on US RMBS securities in a structure where the effective number of borrowers has reduced below the threshold. However, Cl. A-1 has the benefit of support provided by a certificate guarantee. For structured finance securities with third party support, the rating applied is the higher of the support provider's rating and the rating without any consideration of the third-party support. The rating downgrade for Cl. A-1 reflects the rating of the support provider, Assured Guaranty Municipal Corp.
Principal Methodologies
The principal methodology used in this rating was "Rating Transactions Based on the Credit Substitution Approach: Letter of Credit-backed, Insured and Guaranteed Debts" published in May 2017 and available at https://www.moodys.com/researchdocumentcontentpage.aspx?docid=PBC_1068154. Alternatively, please see the Rating Methodologies page on www.moodys.com for a copy of this methodology.
Please note that a Request for Comment was published in which Moody's requested market feedback on potential revisions to one or more of the methodologies used in determining these Credit Ratings. If the revised methodologies are implemented as proposed, it is not currently expected that the Credit Ratings referenced in this press release will be affected. Request for Comments can be found on the rating methodologies page on www.moodys.com.
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 rating:
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.
