DBRS Morningstar Upgrades and Confirms Ratings on Asti Group RMBS II S.r.l.

DBRS Ratings GmbH (DBRS Morningstar) took the following rating actions on the notes issued by Asti Group RMBS II S.r.l. (the Issuer):

-- Class A confirmed at AAA (sf)
-- Class B upgraded to AA (sf) from AA (low) (sf)

The rating actions follow an annual review of the transaction and are based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults, and losses, as of the March 2023 payment date;
-- Portfolio default rate (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables; and
-- Current available credit enhancement to the notes to cover the expected losses at their respective rating levels.

The transaction is a static securitisation of Italian residential mortgages originated and serviced by Cassa di Risparmio di Asti S.p.A. (CR Asti), which originated 87.3% of the initial mortgage pool, and Cassa di Risparmio di Biella e Vercelli S.p.A. (BiverBanca), a previously wholly-owned subsidiary of CR Asti, which originated 12.7% of the pool. Effective in November 2021, Biverbanca was incorporated into CR Asti. The transaction closed in June 2019 with an initial portfolio balance of EUR 988.0 million.

PORTFOLIO PERFORMANCE
As of the March 2023 payment date, loans that were 0 to 30 days, 30 to 60 days, and 60 to 90 days delinquent represented 1.3%, 0.3%, and 0.2% of the outstanding principal balance, respectively, while loans more than 90 days delinquent represented 0.5%. Gross cumulative defaults amounted to 0.5% of the initial portfolio balance to date, with cumulative principal recoveries of 15.6% to date.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and updated its base case PD and LGD assumptions to 9.1% and 12.9%, respectively.

CREDIT ENHANCEMENT
The subordination of the respective junior obligations provides credit enhancement to the rated notes. As of the March 2023 payment date, credit enhancement to the Class A notes increased to 34.5% from 29.1% at the time of the last annual review 12 months ago while credit enhancement to the Class B notes increased to 24.3% from 20.2%.

The transaction benefits from a cash reserve, funded at closing to EUR 17.8 million using subordinated loans granted by Asti and BiverBanca. The reserve provides liquidity support to the rated notes and is available to cover senior expenses, interest on the Class A notes and, as long as the gross cumulative default ratio does not exceed 4.5%, interest on the Class B notes. The reserve is amortising with a target balance equal to 2.0% of the outstanding balance of the rated notes, subject to a floor of EUR 8.9 million. As of the March 2023 payment date, the reserve was at its target of EUR 10.0 million.

BNP Paribas, Succursale Italia (BNP Italy) acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating on BNP Italy, 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 ratings assigned to the rated notes in the transaction, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
There were no Environmental/Social/Governance factors that had a significant or relevant effect on the credit analysis.

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the ratings, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the ratings (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 assumptions for the remaining collateral pool are 9.1% and 12.9%, 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 on the Class A notes would be expected to remain at AAA (sf), ceteris paribus. If the PD increases by 50%, the rating on the Class A notes would be expected to remain at AAA (sf), ceteris paribus. Furthermore, if both the PD and LGD increase by 50%, the rating on the Class A notes would 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)

Class B 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 (low) (sf)
-- 50% increase in PD, expected rating of A (low) (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of AA (low) (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of AA (low) (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of A (low) (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of A (low) (sf)
