DBRS Morningstar Confirms Rating on Dunmore Securities No. 1 DAC

DBRS Ratings GmbH (DBRS Morningstar) confirmed its rating of AAA (sf) on the Class A Notes issued by Dunmore Securities No. 1 DAC (the Issuer).

The rating action follows an annual review of the transaction and is based on the following analytical considerations:

-- Portfolio performance, in terms of delinquencies, defaults and losses.
-- Probability of default (PD), loss given default (LGD) and expected loss assumptions on the remaining receivables.
-- Current available credit enhancement to the Class A Notes to cover the expected losses at the AAA (sf) rating level.

Dunmore Securities No. 1 DAC is a public securitisation of residential mortgages originated by Ulster Bank Ireland DAC (Ulster Bank) secured over properties located in Ireland. Ulster Bank services the mortgage portfolio during the life of the transaction with CSC Capital Markets (Ireland) Limited acting as the replacement servicer facilitator.

On 22 October 2019, DBRS Morningstar transferred the ongoing coverage of the rating assigned to the Issuer to DBRS Ratings GmbH from DBRS Ratings Limited. The lead analyst responsibilities for the transaction have been transferred to Shalva Beshia.

Both DBRS Ratings Limited and DBRS Ratings GmbH are registered with the European Securities and Markets Authority (ESMA) under Regulation (EC) No. 1060/2009 on Credit Rating Agencies, as amended, and are registered Nationally Recognized Statistical Rating Organization (NRSRO) affiliates in the United States and Designated Rating Organization (DRO) affiliates in Canada.

PORTFOLIO PERFORMANCE
As of September 2019, loans with two- to three-months in arrears represented 0.1% of the outstanding portfolio balance and the 90+ days delinquency ratio represented 0.4%, both compared to 0.0% at closing. The cumulative loss ratio remained at 0.0%.

PORTFOLIO ASSUMPTIONS
DBRS Morningstar conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions to 7.4% and 18.2%, respectively.

CREDIT ENHANCEMENT
The transaction’s structure provides 25.5% of credit enhancement to the Class A Notes, up from 23.1% at closing. This includes subordination of the Class Z Notes and the non-amortising general reserve fund.

The transaction benefits from a reserve fund of EUR 34.6 million. The subordinated loan funded by the reserve fund, can be applied to cover shortfalls in senior fees, pay interest on the Class A Notes and credit principal deficiency ledger (PDL) debits on the Class A sub-ledgers.

Principal funds can be diverted to pay shortfalls in senior fees and interest on the Class A Notes. This amount will be subsequently debited to the PDL. The PDL also tracks realised loss and provisions for arrears, gradually increasing the percentage of the outstanding balance that has been debited to the PDL as the severity of arrears increases. This allows excess spread to be captured earlier, to recover any future potential losses, which would otherwise have been released to the seller as deferred consideration.

The Bank of New York Mellon SA/NV Dublin branch (BNY Mellon-Dublin) acts as the account bank for the transaction. Based on DBRS Morningstar’s private rating of BNY Mellon-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 in this transaction to be consistent with the rating assigned to the notes, as described in DBRS Morningstar's "Legal Criteria for European Structured Finance Transactions" methodology.

The transaction structure was analysed in Intex DealMaker.

To assess the impact of changing the transaction parameters on the rating, DBRS Morningstar considered the following stress scenarios as compared with the parameters used to determine the rating (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 7.4% and 18.2%, 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 on the Class A Notes would be expected to fall to AA (high) (sf), assuming no change in the PD. If the PD increases by 50%, the rating on the Class A Notes would be expected to fall to AA (high) (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 (low) (sf).

Class A Notes Risk Sensitivity:
-- 25% increase of the PD, expected rating of AAA (sf)
-- 50% increase of the PD, expected rating of AA (high) (sf)
-- 25% increase of the LGD, expected rating of AAA (sf)
-- 50% increase of the LGD, expected rating of AA (high) (sf)
-- 25% increase of the PD and 25% increase of the LGD, expected rating of AA (high) (sf)
-- 50% increase of the PD and 25% increase of the LGD, expected rating of AA (sf)
-- 25% increase of the PD and 50% increase of the LGD, expected rating of AA (sf)
-- 50% increase of the PD and 50% increase of the LGD, expected rating of AA (low) (sf)
