DBRS Morningstar Confirms Ratings on Fastnet Securities 18 DAC

DBRS Ratings GmbH (DBRS Morningstar) confirmed its ratings on the notes issued by Fastnet Securities 18 DAC as follows:

-- Class A1 at AAA (sf)
-- Class A2 at AAA (sf)
-- Class A3 at AAA (sf)
-- Class B at AA (sf)
-- Class C at A (high) (sf)
-- Class D at BBB (high) (sf)
-- Class E at BB (high) (sf)

The ratings on the Class A1, Class A2, and Class A3 notes (together, the Class A notes) address the timely payment of interest and the ultimate payment of principal on or before the legal final maturity date in January 2061. The rating on the Class B notes addresses the timely payment of interest when most senior and the ultimate payment of principal on or before the legal final maturity date. The ratings on the Class C, Class D, and Class E notes address the ultimate payment of interest and principal on or before the legal final maturity date.

The confirmations 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 June 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 Irish first-lien residential mortgages originated and serviced by Permanent TSB plc (PTSB), which closed in June 2022, with an initial portfolio balance of EUR 3.00 billion of owner-occupied mortgages.

PORTFOLIO PERFORMANCE
As of the June 2023 payment date, loans that were 30 to 60 days and 60 to 90 days delinquent represented 0.06% and 0.04% of the outstanding principal balance, respectively, while loans more than 90 days delinquent amounted to 0.05%. There have not been any repossessions or realised losses to date.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
DBRS Morningstar updated its base case PD and LGD assumptions on the remaining receivables to 1.6% and 10.0%, respectively, compared with 1.4% and 5.2% at the initial rating date, respectively. The higher loss assumptions at the base case level result from the recent release of DBRS Morningstar’s “European RMBS Insight: Irish Addendum”, which penalises loans originated before 2010.

CREDIT ENHANCEMENT
The subordination of the respective junior obligations and the general reserve fund provide credit enhancement to the rated notes. As of the June 2023 payment date, credit enhancement to the Class A notes increased to 15.2% from 12.1% at the time of the initial rating; credit enhancement to the Class B notes increased to 11.5% from 9.1%; credit enhancement to the Class C notes increased to 5.3% from 4.1%; credit enhancement to the Class D notes increased to 2.8% from 2.1%; and credit enhancement to the Class E notes increased to 1.6% from 1.1%.

The transaction benefits from a general reserve fund and a liquidity reserve fund providing credit support and liquidity support, respectively, funded at closing through a subordinated loan. Together, the general reserve and liquidity reserve funds equal 1.0% of the initial total notes balance. As of the June 2023 payment date, the general reserve fund was at EUR 9.1 million and the liquidity reserve fund was at EUR 20.9 million.

BNP Paribas SA, Dublin Branch (BNP Dublin) acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating on BNP Dublin, 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 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 1.6% and 10.0%, 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), ceteris paribus. If the PD increases by 50%, the rating of 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 of the Class A notes would be expected to remain at AAA (sf).
