DBRS Morningstar Upgrades and Confirms Ratings on Fastnet Securities 13 DAC

RMBS
September 30, 2021

DBRS Ratings GmbH (DBRS Morningstar) took the following rating actions on the notes issued by Fastnet Securities 13 DAC (the Issuer):

-- Class A confirmed at AAA (sf)
-- Class B confirmed at AAA (sf)
-- Class C upgraded to AAA (sf) from AA (high) (sf)
-- Class D upgraded to AA (high) (sf) from A (high) (sf)

The ratings on the Class A, Class B, and Class C notes address the timely payment of interest and ultimate payment of principal on or before the legal final maturity date in April 2057. The rating on the Class D notes addresses the ultimate payment of interest and principal on or before the legal final maturity date.

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 July 2021 payment date;
-- Probability of default (PD), loss given default (LGD), and expected loss assumptions on the remaining receivables;
-- Current available credit enhancement to the notes to cover the expected losses at their respective rating levels; and
-- Current economic environment and an assessment of sustainable performance, as a result of the Coronavirus Disease (COVID-19) pandemic.

The Issuer is a static securitisation of first-ranking prime Irish residential mortgages granted for primary residences, originated and serviced by permanent tsb p.l.c. (PTSB). The transaction closed in October 2017 with an initial collateral balance of EUR 526.2 million, which has since been reduced to EUR 205.3 million as of 31 July 2021.

PORTFOLIO PERFORMANCE
As of 31 July 2021, loans one to two months and two to three months in arrears represented 0.2% and 0.1% of the outstanding portfolio balance, respectively, while loans more than three months in arrears represented 0.9%. There have not been any repossessions or realised losses 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 3.1% and 6.2%, respectively.

CREDIT ENHANCEMENT
Credit enhancement to the rated notes in the transaction is provided by the subordination of the respective junior obligations and the general reserve fund. The transaction continues to deleverage steadily, resulting in increased credit enhancement available to the rated notes, which prompted the rating upgrades. As of the July 2021 payment date, credit enhancement to the Class A, Class B, Class C, and Class D notes has increased to 57.0%, 42.7%, 28.4%, and 16.0%, respectively, from 44.1%, 32.9%, 21.6%, and 11.9%, respectively, 12 months ago.

The transaction benefits from a general reserve fund and a liquidity reserve fund that provide credit and liquidity support, respectively. The reserves were funded at closing through a subordinated loan from PTSB and together equal 2.0% of the total initial notes’ balance. The general reserve fund is amortising with a target balance equal to 2.0% of the initial portfolio balance minus the current liquidity reserve fund balance, and as of the July 2021 payment date was at its target balance of EUR 6.5 million. The liquidity reserve fund is amortising with a target balance equal to 2.0% of the outstanding rated notes balance, and as of the July 2021 payment date was at its target balance of EUR 4.0 million.

The Bank of New York Mellon, London branch (BNYML) acts as the account bank for the transaction. Based on the DBRS Morningstar public rating of BNYML at AA, 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, 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 immediate economic contraction, leading in some cases to 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. The ratings are based on additional analysis 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 rate for self-employed borrowers, assumed a moderate decline in residential property prices, and conducted additional sensitivity analysis to determine that the transaction benefits from sufficient liquidity support to withstand high levels of payment holidays or payment moratoriums in the portfolio.

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 of the current pool of loans for the Issuer are 3.1% and 6.2%, 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 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)

-- 25% increase in PD and 25% 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)

-- 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)
