DBRS Morningstar Confirms Ratings of Dilosk RMBS No. 3 DAC

DBRS Ratings Limited (DBRS Morningstar) confirmed its ratings of the notes issued by Dilosk RMBS No. 3 DAC (the Issuer) as follows:

-- Class A Notes confirmed at AAA (sf)
-- Class B Notes confirmed at AA (high) (sf)
-- Class C Notes confirmed at A (high) (sf)
-- Class D Notes confirmed at BBB (sf)

The rating of the Class A Notes addresses the timely payment of interest and ultimate repayment of principal on or before the final maturity date. The ratings of the Class B to Class D Notes address the ultimate payment of interest while junior, but timely payment of interest when the senior-most tranche, and ultimate repayment of principal on or before the 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 January 2020 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.

The Issuer is a securitisation of prime Irish buy-to-let mortgages originated and serviced by Dilosk DAC (Dilosk) granted to individuals, corporates, and pension trusts between 2017 and 2019. All primary servicing activities are delegated to Link Asset Services Limited.

PORTFOLIO PERFORMANCE
As of January 2020, none of the loans were in arrears, unchanged from closing.

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 5.8% and 6.4%, respectively.

CREDIT ENHANCEMENT AND RESERVES
As of the January 2020 payment date, credit enhancement to the Class A, Class B, Class C, and Class D Notes was 22.3%, 15.4%, 9.3%, and 3.7%, respectively, down slightly from 22.5%, 16.0%, 10.3%, and 5.0% at the initial rating because of the use of principal receipts to fund the liquidity reserve fund on the first interest payment date in October 2019. Credit enhancement is provided by subordination of the junior notes and the general reserve fund.

The general reserve fund is nonamortising and is currently at its target level of EUR 5.2 million, equal to 2.5% of original principal balance of the Class A, Class B, Class C, Class D, and Class Z1 notes. The general reserve is available to cover senior fees, interest shortfall, and principal losses (via the principal deficiency ledgers) on the Class A to Class D Notes.

The liquidity reserve fund initially had a zero balance at closing and was funded through available principal receipts on the first payment date in October 2019. The liquidity reserve fund is currently funded to its target level of EUR 2.5 million, equal to 1.5% of the outstanding Class A Notes, and is subject to a floor of 0.75% of the original Class A Notes balance. The liquidity reserve fund covers senior fees and interest on the Class A Notes.

The Bank of New York Mellon, London Branch acts as the account bank for the transaction. Based on the DBRS Morningstar rating of The Bank of New York Mellon, London Branch at AA (high), 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.

DBRS Morningstar analysed the transaction structure in Intex DealMaker.

The Coronavirus Disease (COVID-19) and the resulting isolation measures have caused an economic contraction, leading to sharp increases in unemployment rates and income reductions for many borrowers. DBRS Morningstar anticipates that delinquencies may arise in the coming months for many RMBS transactions, some meaningfully. The ratings are based on additional analysis and, where appropriate, additional stresses to expected performance as a result of the global efforts to contain the spread of the coronavirus. On 16 April 2020, the DBRS Sovereign group published its outlook on the impact to key economic indicators for the 2020-22 time frame. For details see the following commentary: https://www.dbrsmorningstar.com/research/359679/global-macroeconomic-scenarios-implications-for-credit-ratings.

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 5.8% and 6.4%, 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 fall to AA (high) (sf), assuming no change in the PD. If the PD increases by 50%, the rating of 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 in LGD, expected rating of AA (high) (sf)
-- 50% increase in LGD, expected rating of AA (high) (sf)
-- 25% increase in PD, expected rating of AA (high) (sf)

-- 25% increase in PD and 25% increase in LGD, expected rating of AA (high) (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of AA (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of AA (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of AA (low) (sf)

Class B Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (high) (sf)
-- 50% increase in LGD, expected rating of AA (sf)
-- 25% increase in PD, expected rating of AA (sf)
