DBRS Morningstar Confirms and Upgrades Ratings on Four RMBS Santander Transactions

RMBS
October 04, 2019

DBRS Ratings GmbH (DBRS Morningstar) took the following rating actions on the bonds issued by four Santander Spanish residential mortgage-backed securities (RMBS) transactions:

FTA RMBS Santander 1 (SAN1):
-- Series A Notes confirmed at AAA (sf)
-- Series B Notes confirmed at CCC (sf)
-- Series C Notes confirmed at C (sf)

FTA RMBS Santander 3 (SAN3):
-- Series A Notes confirmed at AAA (sf)
-- Series B Notes upgraded to B (high) (sf) from B (low) (sf)
-- Series C Notes confirmed at C (sf)

FT RMBS Santander 4 (SAN4):
-- Series A Notes confirmed at AA (sf)
-- Series B Notes upgraded to B (sf) from B (low) (sf)
-- Series C Notes confirmed at C (sf)

FT RMBS Santander 5 (SAN5):
-- Series A Notes confirmed at AA (sf)
-- Series B Notes upgraded to B (low) (sf) from CCC (sf)
-- Series C Notes confirmed at C (sf)

In each transaction, the ratings on the Series A Notes address the timely payment of interest and ultimate payment of principal on or before the respective legal final maturity dates. The ratings on the Series B Notes and Series C Notes address the ultimate payment of interest and principal on or before the respective legal final maturity dates.

The rating actions follow an annual review of the transactions and are based on the following analytical considerations:

-- Portfolio performances, in terms of delinquencies, defaults and losses.
-- Portfolio default rates (PD), loss given default (LGD) and expected loss assumptions on the remaining pools of receivables.
-- Current available credit enhancement to the Series A and Series B Notes to cover the expected losses at their respective rating levels. The Series C Notes of each transaction were issued to fund the cash reserve and are in a first-loss position supported only by available excess spread. Given the characteristics of the Series C Notes as defined in the transaction documents, the default would most likely be recognised at maturity or following an early termination of the transaction.

All four transactions are securitisations of Spanish first-lien residential mortgage loans and include a portion of borrowers with higher-risk characteristics. The pool of SAN1 was originated and is serviced by Banco Santander S.A. (Santander). The pools of SAN3 and SAN4 were originated by Santander and Banco de Crédito Español (Banesto, integrated in Santander since 2013) and are serviced by Santander. The pool of SAN5 is originated by Santander, Banesto and Banco Banif S.A.U. and is also serviced by Santander.

PORTFOLIO PERFORMANCE
The portfolios are performing within DBRS Morningstar’s expectations. As of the latest payment dates, the 90+ delinquency ratios stood at 1.0%, 0.7%, 0.9%, 1.0% of the outstanding collateral pools of SAN1, SAN3, SAN4 and SAN5, respectively. The cumulative default ratios were 4.0%, 2.5%, 2.0%, and 1.3%, computed on the original portfolio balances of SAN1, SAN3, SAN4 and SAN5, respectively.

PORTFOLIO ASSUMPTIONS
DBRS Morningstar conducted loan-by-loan analyses on the remaining collateral pools of receivables and updated its PD and LGD assumptions as follows:

-- In SAN1, the base case PD and LGD are 12.3% and 31.0%, respectively;
-- In SAN3, the base case PD and LGD are 7.5% and 34.3%, respectively;
-- In SAN4, the base case PD and LGD are 9.2% and 35.3%, respectively;
-- In SAN5, the base case PD and LGD are 10.9% and 32.2%, respectively.

CREDIT ENHANCEMENT
The credit enhancements available to the Series A and B Notes continue to increase as the transactions continue to deleverage. The Series C Notes funded the reserve funds and hence do not benefit from credit enhancement.

The credit enhancements consist of the overcollateralisation provided by the outstanding collateral portfolios and include the Reserve Funds in all transactions. The credit enhancements were as follows:

-- In SAN1, the Series A and Series B Notes credit enhancements were 47.1% and 3.9% as of the June 2019 payment date, compared with 44.2% and 3.7% as of the September 2018 payment date;
-- In SAN3, the Series A and Series B Notes credit enhancements were 41.6% and 6.1% as of the August 2019 payment date, compared with 38.2% and 5.4% as of the August 2018 payment date;
-- In SAN4, the Series A and Series B Notes credit enhancements were 33.8% and 5.8% as of the June 2019 payment date, compared with 31.7% and 5.4% as of the September 2018 payment date;
-- In SAN5, the Series A and Series B Notes credit enhancements were 33.7% and 6.1% as of the July 2019 payment date, compared with 30.7% and 5.4% as of the July 2018 payment date.

The reserve funds were funded through the issuances of junior series and are available to cover principal losses, senior fees and interest shortfall on the rated Notes. As of the latest payment dates, the reserves were at EUR 32.0 million in SAN1, EUR 265.5 million in SAN3, EUR 123.1 million in SAN4 and EUR 57.7 million in SAN5. None of the reserve funds are at their target levels but they have been increasing over the last year in all transactions.

Banco Santander S.A. acts as the Account Bank of all four transactions. Based on the DBRS Morningstar account bank reference rating of A (high), one notch below the DBRS Morningstar public Long-Term Critical Obligations Rating (COR) of Banco Santander of AA (low), the downgrade provisions outlined in the transactions’ documents, and other mitigating factors inherent in the transactions’ structures, DBRS Morningstar considers the risk arising from the exposure to the Account Bank in all four transactions to be consistent with the ratings assigned to the Series A Notes of each transaction, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

The transaction structures were analysed in Intex DealMaker.

To assess the impact of changing the transactions’ parameters on the ratings, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):

-- DBRS Morningstar expected a lifetime base case PD and LGD for the pools based on a review of the current assets.
Adverse changes to asset performances may cause stresses to base case assumptions and, therefore, have a negative effect on credit ratings.

-- In SAN1, the base case PD and LGD of the pool of mortgages are 12.3% and 31.0%, respectively. At the AAA (sf) rating level, the corresponding PD is 36.0% and the LGD is 51.4%.
-- In SAN3, the base case PD and LGD of the pool of mortgages are 7.5% and 34.3%, respectively. At the AAA (sf) rating level, the corresponding PD is 27.7% and the LGD is 54.6%.
-- In SAN4, the base case PD and LGD of the pool of mortgages are 9.2% and 35.3%, respectively. At the AA (sf) rating level, the corresponding PD is 27.4% and the LGD is 51.0%.
-- In SAN5, the base case PD and LGD of the pool of mortgages are 10.9% and 32.2%, respectively. At the AA (sf) rating level, the corresponding PD is 30.7% and the LGD is 48.1%.

-- The Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. Considering SAN1 as an example, if the LGD increases by 50%, the rating of the Series A Notes would be expected to remain at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Series A Notes would be expected to remain at AAA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating of the Series A Notes would be expected to remain at AAA (sf).

-- The Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the rating of the Series A Notes would be expected to remain at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Series A Notes would be expected to remain at AAA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating of the Series A Notes would still be expected to remain at AAA (sf).
