Rating action

Scope Ratings GmbH (Scope) has performed the following rating actions:

• Class A (ISIN ES0305545008), EUR 249,699,495 outstanding: affirmed at AAA_SF
   
• Class Z (ISIN ES0305545016), EUR 50,000,000 outstanding: affirmed at AA+_SF
   
• Class B (ISIN ES0305545024), EUR 26,400,000 outstanding: affirmed at A-_SF
   
• Class C (ISIN ES0305545032), EUR 21,600,000 outstanding: not rated

The rating actions incorporate the correction of a model error in the post-processing of model results with regards to class B notes. The previous model results excluded one of the scenarios dependent on prepayment parameters.

The model error had a negative impact on class B notes, which was compensated by the additional build-up of credit support since our last monitoring as a result of the notes sequential repayment. Scope undertook a full analytical review, considering the investor reports with information up to interest payment date 15 March 2024 which concluded in no impact on the outstanding ratings.

Transaction overview

The transaction is a Spanish consumer RMBS securitisation issued in May 2021. A detailed description of the transaction’s features and analytical assumptions at closing can be found in the rating report available at Scope’s website.

As of the reporting cut-off date on 08 March 2024, the underlying portfolio of assets has an expected remaining weighted average life (assuming zero defaults and prepayments) of around 12.5 years and the pool factor stands at 0.7. Credit enhancement has evolved: with regards to the rated class A, Z and B notes, it has increased to respectively 30.2%, 15.8% and 8.2% from 22.4%, 12.0% and 6.5% at closing.

The amortising reserve fund is at 100% of its target level, equivalent to 2% of the outstanding portfolio balance.

On the latest interest payment date, rated class A, Z and B notes excess spread equalled around 0.4% (measured as the realised portfolio yield minus the weighted average cost of the rated notes minus senior expenses, annualised).

The issuer remains primarily exposed to the following counterparties: Unión de Créditos Inmobiliarios, S.A., Establecimiento Financiero de Crédito as originator and servicer, Banco Santander, S.A. as issuer account bank, BNP Paribas as cap hedging counterparty and BNP Paribas Securities Services Sucursal en Espana as paying agent account bank.

Rating rationale

The review addressed i) the observed performance of the collateral as of the review cut-off date; ii) Scope’s forward-looking performance assumptions in the context of the expected macro-economic environment over the transaction’s remaining life; iii) the transaction’s updated asset and liability structure; and iv) the issuer’s exposure to key transaction parties.

Key rating drivers

The key rating drivers remain aligned with those disclosed on our initial rating action release dated 6 May 2021. One key driver (Simple structure) is considered an ESG factor.

Beyond the key rating drivers, other relevant rating factors which we considered during the annual review were the following:

Observed collateral performance¹. Overall, the portfolio has performed in line with Scope’s expectations at closing. The following key metrics as of the reporting cut-off date reflect the good overall portfolio performance: the cumulative default rate at 8bps and the 90 days-past-due dynamic delinquency rate at 34bps. Realised cumulative defaults since closing have been fully provisioned for with available excess spread.

Expected collateral performance^1,3. Scope estimated the portfolio’s remaining lifetime default rates through an inverse Gaussian distribution. The mean parameter of the distribution was adjusted to 5.3% from 6.0% at closing date, which addresses the expected impact of portfolio amortisation against the backdrop of positive borrower performance to date. Scope has also adjusted the coefficient of variation parameter distribution to 94.7% from 85.0% at closing to account for the lower mean base. Other asset assumptions, including on the recovery and prepayment rates, remain unchanged.

Notes amortisation^1,2. The updated capital structure is positive for the rated class A, Z and B notes. The realised deleveraging of the capital structure reflects the sequential notes’ amortisation in accordance with the transaction waterfall.

Key rating-change drivers

All else equal, the following factors may constitute upside or downside rating drivers:

• A material deviation of observed transaction performance from Scope’s current performance assumptions, or
   
• A material change in Scope’s forward-looking macro-economic outlook.

All else equal, the following factors may constitute upside rating drivers:

• Continued deleveraging of the capital structure and a reduction of the transaction’s risk horizon.

All else equal, the following factors may constitute downside rating drivers:

• A rating downgrade of a key counterparty beyond a level compliant with Scope’s Counterparty Risk Methodology, or
   
• A depletion of the reserve fund beyond a level commensurate with the then-current rating of the notes in accordance with Scope’s General Structured Finance Methodology.

Quantitative analysis and assumptions

Scope used a proprietary cash flow model to calculate the expected loss and expected weighted average life of each rated tranche, considering the transaction’s assets and liability structure. Asset cash flows are projected based on the securitised portfolio amortisation schedule and on committee-determined performance assumptions, which reflect the characteristics and quality of the portfolio. The model replicates the transaction’s key structural features, including the capital structure, the order of priority of the issuer’s liabilities, and enhancement features such as excess spread and cash reserves.

The key analytical assumptions include the following: an inverse-Gaussian distribution of portfolio remaining lifetime defaults, with a mean of 5.3% and a coefficient of variation of 94.7%; rating-conditional recovery rates ranging from 75.0% under a B scenario to 45.0% under a AAA scenario; high and low constant prepayment rate scenarios of 5.0% and 1.5%, respectively; stressed senior fees of 0.5%, and a portfolio yield compression and basis risk stress of 0.2% and 0.3%, respectively.

Sensitivity analysis

Scope tested the resilience of the credit rating against deviations in the main input parameters: the portfolio mean default rate and the portfolio recovery rate. This analysis has the sole purpose of illustrating the sensitivity of the rating to input assumptions and is not indicative of expected or likely scenarios.

• A 50% increase in the mean default rate assumption has a one-notch quantitative impact on the class A notes, a three-notch quantitative impact on the class Z notes and a three-notch quantitative impact on the class B notes.
   
• A 50% decrease in Scope’s rating-conditional recovery rate assumptions has a zero-notch quantitative impact on the class A notes, a three-notch quantitative impact on the class Z notes and a three-notch quantitative impact on the class B notes.

Stress testing
Stress testing was performed by applying Credit-Rating-adjusted recovery rate assumptions.

Cash flow analysis
Scope Ratings performed a cash flow analysis of the transaction with the use of Scope Rating’s Cash Flow Model Version 2.0, incorporating default and recovery rate assumptions over the portfolio’s amortisation period, taking into account the transaction’s main structural features, such as the notes’ priorities of payment, the notes’ size and coupons. The outcome of the analysis is an expected loss and an expected weighted average life for the notes.
