-- Class C notes confirmed at A (high) (sf)
-- Class D notes confirmed at BBB (high) (sf)

Fastnet 17:

-- Class B notes confirmed at AA (high) (sf)

The credit ratings on the Class A1, Class A2, and Class A3 notes address the timely payment of interest and the ultimate payment of principal on or before the final maturity date in December 2058. The credit ratings on the Class B and Class C notes address the timely payment of interest when most senior and the ultimate payment of principal on or before the final maturity date. The credit ratings on the Class D and Class E notes address the ultimate payment of interest and principal on or before the final maturity date.

The credit rating actions follow an annual review of the transactions and are based on the following analytical considerations:
-- Portfolio performance, in terms of delinquencies, defaults, and losses, as of the June 2024 payment date of each transaction;
-- Portfolio default rate (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 credit rating levels;
-- The sensitivity of the most junior notes to high interest rate environments.

The transactions are static securitisations of Irish first-lien residential mortgages originated and serviced by Permanent TSB plc (PTSB), which closed in July 2021. Fastnet 16 had an initial portfolio balance of EUR 3.95 billion of owner-occupied mortgages while Fastnet 17 had an initial portfolio balance of EUR 1.03 billion of both owner-occupied and buy-to-let mortgages.

PORTFOLIO PERFORMANCE
Fastnet 16:
As of the June 2024 payment date, loans that were 30 to 60 days and 60 to 90 days delinquent represented 0.2% and 0.1% of the outstanding principal balance, respectively, while loans more than 90 days delinquent represented 0.4%. There have not been any repossessions or realised losses to date.

Fastnet 17:
As of the June 2024 payment date, loans that were 30 to 60 days and 60 to 90 days delinquent represented 1.5% and 0.7% of the outstanding principal balance, respectively, while loans more than 90 days delinquent represented 2.9%. There have not been any repossessions or realised losses to date.

PORTFOLIO ASSUMPTIONS AND KEY DRIVERS
For Fastnet 16, Morningstar DBRS updated its base case PD and LGD assumptions on the remaining receivables to 1.8% and 10.1%, respectively. For Fastnet 17, Morningstar DBRS updated its base case PD and LGD assumptions to 7.8% and 13.5%, respectively, which are higher than at the time of the last annual review 12 months ago due to a worsened arrears profile.

CREDIT ENHANCEMENT
The subordination of the respective junior obligations and the general reserve funds provide credit enhancement to the rated notes in the respective transactions.

As of the June 2024 payment date, in Fastnet 16, credit enhancement to the Class A notes increased to 25.9% from 21.7% at the time of the previous annual review 12 months ago; credit enhancement to the Class B notes increased to 19.5% from 16.3%; credit enhancement to the Class C notes increased to 9.3% from 7.7%; credit enhancement to the Class D notes increased to 5.5% from 4.5%; and credit enhancement to the Class E notes increased to 3.4% from 2.7%.

In Fastnet 17, credit enhancement to the Class A notes increased to 46.8% from 39.3% at the time of the previous annual review 12 months ago; credit enhancement to the Class B notes increased to 36.1% from 30.4%; credit enhancement to the Class C notes increased to 22.0% from 18.3%; credit enhancement to the Class D notes increased to 17.2% from 14.3%; and credit enhancement to the Class E notes increased to 13.7% from 11.2%.

The transactions benefit from a general reserve fund providing credit support and a liquidity reserve fund providing liquidity support, both funded at closing through a subordinated loan. Together, the general reserve and liquidity reserve funds equal 1.0% of the initial total notes' balance in each transaction. As of the June 2024 payment date, the general reserve fund for Fastnet 16 was at EUR 25.0 million and the liquidity reserve fund was at EUR 14.5 million while the general reserve fund for Fastnet 17 was at EUR 7.9 million and the liquidity reserve fund was at EUR 2.5 million.

For Fastnet 16, the downgrade on the Class E Notes follows their high sensitivity to potential compression of the net excess spread between the assets and the liabilities in high interest rate scenarios, which Morningstar DBRS continues to monitor.

BNP Paribas Ireland - Dublin Branch (BNP Ireland) acts as the account bank for the transactions. Based on Morningstar DBRS' private credit rating on BNP Ireland, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structures, Morningstar DBRS considers the risk arising from the exposure to the account bank to be consistent with the credit ratings assigned to the notes in the transactions, as described in Morningstar DBRS' "Legal Criteria for European Structured Finance Transactions" methodology.

Morningstar DBRS' credit ratings on the rated notes address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents.

Morningstar DBRS' credit ratings do not address nonpayment risk associated with contractual payment obligations contemplated in the applicable transaction documents that are not financial obligations.

Morningstar DBRS' long-term credit rating provides opinions on risk of default. Morningstar DBRS considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.

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

Sensitivity Analysis: To assess the impact of changing the transaction parameters on the credit rating, Morningstar DBRS considered the following stress scenarios as compared with the parameters used to determine the credit rating (the base case):

-- Morningstar DBRS 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.
-- For Fastnet 16, the base case PD and LGD assumptions for the remaining collateral pool are 1.8% and 10.1%, respectively.
-- For Fastnet 17, the base case PD and LGD assumptions for the remaining collateral pool are 7.8% and 13.5%, respectively.
