DBRS Morningstar Confirms Ratings on Mulcair Securities No.2 DAC

RMBS
June 23, 2023

DBRS Ratings GmbH (DBRS Morningstar) confirmed its ratings on the notes issued by Mulcair Securities No.2 DAC (the Issuer) as follows:

-- Class A at AAA (SF)
-- Class B at AA (SF)
-- Class C at AA (low) (SF)
-- Class D at A (low) (SF)
-- Class E at BBB (low) (SF)
-- Class F at BB (sf)

The rating on the Class A notes addresses the timely payment of interest and the ultimate repayment of principal by the legal final maturity date in April 2072. The ratings on the Class B and Class C notes address the ultimate payment of interest and principal by the legal final maturity date, and the timely payment of interest while they are the senior-most class of notes outstanding. The ratings on the Class D, Class E, and Class F notes address the ultimate payment of interest and the ultimate repayment of principal by the legal final maturity date.

The rating 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 April 2023 payment date;
-- Probability of default (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 securitisation of reperforming owner-occupied and buy-to-let mortgages secured over properties in the Republic of Ireland. The mortgages were originated by The Governor and Company of the Bank of Ireland (Bank of Ireland), Bank of Ireland Mortgage Bank, and ICS Building Society. Bank of Ireland services the portfolio.

PORTFOLIO PERFORMANCE
As of 31 March 2023, loans two to three months in arrears represented 0.6% of the outstanding portfolio balance, up from 0.5% in April 2022. Loans more than three months in arrears represented 2.1% of the outstanding portfolio balance, down from 3.6% in April 2022. Cumulative principal losses amounted to 1.4% of the original portfolio balance.

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 at the B (sf) rating level to 16.7% and 10.4%, respectively.

CREDIT ENHANCEMENT
As of the April 2023 payment date, credit enhancement available to the Class A, Class B, Class C, Class D, Class E, and Class F notes was 39.2%, 31.4%, 25.9%, 21.0%, 18.1%, and 16.3%, respectively, up from 32.1%, 25.7%, 21.2%, 17.1%, 14.8%, and 13.3%, respectively, at the time of the initial rating. Credit enhancement consists of overcollateralisation and subordination of the junior notes. A general reserve fund also provides credit support to the Class B to Class F notes via the principal deficiency ledgers (PDLs).
The transaction benefits from a senior reserve fund, which covers any shortfall in senior fees and interest payments on the Class A and Class B notes. It is currently at its target level of EUR 4.3 million, equal to 2% (of 100/95) of the Class A and Class B notes’ outstanding balance. The transaction also benefits from the general reserve fund, which covers interest shortfalls on the Class C to Class F notes, as well as principal losses via the PDLs on the Class B to Class F notes. It is currently at its target level of EUR 0.9 million, equal to 2% (of 100/95) of the Class C to Class F notes’ aggregate outstanding balance.

The Bank of New York Mellon SA/NV - London Branch (BNY Mellon London) acts as the account bank for the transaction. Based on DBRS Morningstar’s public rating of AA (high) on BNY Mellon London, 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.

Natixis S.A. acts as the interest rate cap provider for the transaction. DBRS Morningstar's private rating on Natixis S.A. is consistent with the First Rating Threshold as described in DBRS Morningstar's "Derivative Criteria for European Structured Finance Transactions" methodology.

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 of the current pool of loans for the Issuer at the B (sf) rating level are 18.3% and 10.4%, 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 be expected to fall to AA (high) (sf).
