DBRS Morningstar Confirms Rating of Sardegna Re-Finance S.r.l.

DBRS Ratings GmbH (DBRS Morningstar) confirmed its AA (sf) rating on the Class A notes issued by Sardegna Re-Finance S.r.l. (the Issuer).

The rating addresses the timely payment of interest and ultimate payment of principal on or before the legal final maturity date in December 2060.

The confirmation follows an annual review of the transaction and is based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults, and losses as of the September 2020 payment date.
-- Probability of default (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables.
-- High geographical concentration in the Italian region of Sardinia.
-- Current available credit enhancement to the Class A notes to cover the expected losses at the AA (sf) rating level.
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The Issuer is a securitisation of first-lien residential mortgages originated and serviced by Banco di Sardegna S.p.A. (BdS). BDS is part of BPER Group and BPER S.p.A. is the majority shareholder of BdS. Sardegna Re-Finance S.r.l. issued two classes of floating-rate notes, the Class A notes and Class J notes, in December 2017. The transaction follows the standard structure under Italian securitisation law. The transaction’s ramp-up period, during which the Issuer could acquire further portfolios, ended in December 2018.

PORTFOLIO PERFORMANCE
As of the September 2020 payment date, transaction delinquencies remained low: loans that were one- to two-month and two- to three-month delinquent represented 0.2% and 0.3% of the portfolio balance, respectively, while loans more than three-month delinquent represented 0.1%. Gross cumulative defaults amounted to 0.7% of the original collateral balance.

The performance of the transaction is exposed to the economic performance of the island of Sardinia, as 84.1% of the current portfolio is located in that region. DBRS Morningstar considers that the concentration risk is commensurate with the current AA (sf) rating of the notes.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions to 6.4% and 9.1%, respectively.

CREDIT ENHANCEMENT
The junior obligations provide credit enhancement to the Class A notes. As of the September 2020 payment date, credit enhancement to the Class A was 28.4%, up from 25.1%, one year ago.

The transaction benefits from an amortising cash reserve account, which is available to cover senior expenses and missed interest payments on the Class A notes. This account was initially funded with EUR 22.5 million, and its target amount is the higher of 1.5% of the outstanding performing portfolio balance and 1.75% of the outstanding principal of the Class A notes. The cash reserve is currently funded at EUR 23.3 million and has been at its target since closing.

BNP Paribas Securities Services SCA/Milan acts as the account bank for the transaction. Based on the DBRS Morningstar private rating of BNP Paribas Securities Services SCA/Milan, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, DBRS Morningstar considers the risk arising from the exposure to the account bank to be consistent with the rating assigned to the Class A notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

DBRS Morningstar analysed the transaction structure in Intex DealMaker.

The Coronavirus Disease (COVID-19) and the resulting isolation measures have caused an economic contraction, leading to sharp increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may continue to increase in the coming months for many RMBS transactions, some meaningfully. The ratings are based on additional analysis and adjustments to expected performance as a result of the global efforts to contain the spread of the coronavirus.

For this transaction, DBRS Morningstar increased the expected default rates for self-employed borrowers, assumed a moderate decline in residential property prices, and conducted additional sensitivity analysis to determine that the transactions benefit from sufficient liquidity support to withstand high levels of payment holidays in the portfolio. As of the September 2020 payment date, around 8.0% of the current portfolio balance benefitted from a payment moratorium.

To assess the impact of changing the transaction parameters on the rating, 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 pool based on a review of the current assets. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.
-- The base case PD and LGD of the current pool of loans for the Issuer are 6.4% and 9.1%, respectively.
-- 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 Class A would be expected to remain at AA (sf), assuming no change in the PD. If the PD increases by 50%, the rating of the Class A would be expected to remain at AA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating of the Class A would be expected to remain at AA (sf).

Class A Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (sf)
-- 50% increase in LGD, expected rating of AA (sf)
-- 25% increase in PD, expected rating of AA (sf)
-- 50% increase in PD, expected rating of AA (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of AA (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of AA (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of AA (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of AA (sf)
