DBRS Morningstar Upgrades Rating on Sardegna Re-Finance S.r.l.

RMBS
December 01, 2022

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

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

The upgrade 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 2022 payment date.
-- Portfolio default rate (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables.
-- High geographical concentration in the Italian region of Sardinia; and,
-- The current level of credit enhancement available to the Class A notes to cover the expected losses at their AAA (sf) rating level.

The transaction 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 the 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 2022 payment date, loans that were one to two months and two to three months delinquent represented 0.4% and 0.1% of the portfolio balance, respectively, while loans more than three months delinquent represented 0.6%. Gross cumulative defaults amounted to 0.8% of the original collateral balance, of which 2.4% has been recovered so far.

The performance of the transaction is exposed to the economic performance of the region of Sardinia, as 85.0% of the current portfolio is located in that region. DBRS Morningstar has factored the concentration risk into its asset analysis and considers that the concentration risk is commensurate with the current AAA (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 7.7% and 15.8%, respectively.

CREDIT ENHANCEMENT
The junior obligations provide credit enhancement to the Class A notes. As of the September 2022 payment date, credit enhancement to the Class A was 37.8%, up from 33.0% at the last annual review, and prompted the upgrade of the Class A notes.

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 17.5 million and has been at its target since closing.

BNP Paribas Succursale Italia acts as the account bank for the transaction. Based on the DBRS Morningstar private rating of BNP Paribas Succursale Italia, 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.

Sensitivity Analysis: 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 7.7% and 15.8%, 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 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 Class 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 Class A notes would also be expected to remain at AAA (sf).

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