DBRS Morningstar Takes Rating Actions on Dilosk RMBS No. 2 DAC, Resolving DBRS Morningstar’s Error

DBRS Ratings Limited (DBRS Morningstar) took rating actions on the following classes of notes issued by Dilosk RMBS No. 2 DAC (the Issuer):

-- Class A confirmed at AAA (sf)
-- Class B confirmed at AA (high) (sf)
-- Class C downgraded to A (sf) from AA (sf)
-- Class D downgraded to BBB (sf) from A (sf)
-- Class E downgraded to B (high) (sf) from BB (high) (sf)
-- Class F downgraded to CCC (sf) from BB (sf)

The rating on the Class A notes addresses the timely payment of interest and ultimate payment of principal on or before the legal final maturity date. The ratings on the Class B, Class C, Class D, Class E and Class F notes address the ultimate payment of interest and principal on or before the legal final maturity date while junior, and timely payment of interest while the senior-most class outstanding.

The rating actions follow an annual review of the transaction and are based on the following analytical considerations:

-- Correction of a cash flow input error made by DBRS Morningstar at the time of the initial rating.
-- 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 notes to cover the expected losses at their respective rating levels.

Dilosk RMBS No. 2 DAC is a securitisation of residential mortgage loans originated by Pepper Finance Corporation (Ireland) DAC (formerly, GE Capital Woodchester Home Loans Limited) and Leeds Building Society.

The downgrades on the Class C, D, E and F notes are driven solely by a correction made to the implementation of the coupon caps applicable to each class of rated notes in DBRS Morningstar’s cash flow analysis. At the time of the DBRS Morningstar initial rating, the coupon caps of either 6.0% or 8.0% applicable to the rated notes were incorrectly entered into DBRS Morningstar’s cash flow engine as 0.06% and 0.08%, respectively.

This was an error solely on the part of DBRS Morningstar and is not connected in any way to the transaction collateral performance, which DBRS Morningstar considers to be in line with initial expectations, or to the data and information provided by the Issuer for the purposes of providing these ratings, which DBRS Morningstar considers to be of satisfactory quality.

PORTFOLIO PERFORMANCE
As of the end of August 2019, loans that were two- to three-months in arrears represented 1.0% of the outstanding portfolio balance, the 90+ delinquency ratio was 2.4% and the cumulative default ratio was 4.2%.

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 for the performing portfolio to 20.1% and 25.7%, respectively.
CREDIT ENHANCEMENT
As of the September 2019 payment date, credit enhancement to the Class A, B, C, D, E and F notes was 41.0%, 34.2%, 29.0%, 22.7%, 13.4% and 10.2% respectively, up from 39.1%, 32.6%, 27.6%, 21.6%, 12.6% and 9.6% respectively, at the DBRS Morningstar initial rating. In each case, credit enhancement is provided by subordination of junior classes, and amounts standing to the credit of the general reserve fund above the first target level.

The transaction benefits from a general reserve fund of EUR 8.3 million. Amounts standing to the credit of the general reserve fund up to the first target level of EUR 2.6 million are available to cover senior fees and Class A interest, while amounts above the first target level and up to the second target level of EUR 5.7 million are available to cover senior fees, interest and principal (via the principal deficiency ledgers) to the rated notes.

Citibank N.A., London Branch acts as the account bank for the transaction. Based on the DBRS Morningstar private rating of Citibank N.A., London Branch, 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.

The transaction structure was analysed in Intex DealMaker.

DBRS Morningstar does not audit or independently verify the data or information it receives in connection with the rating process.

The lead analyst responsibilities for this transaction have been transferred to Andrew Lynch.

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 20.1% and 25.7%, 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 (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 A (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 BBB (sf).

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

Class B Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (low) (sf)
-- 50% increase in LGD, expected rating of A (low) (sf)
-- 25% increase in PD, expected rating of A (low) (sf)
-- 50% increase in PD, expected rating of BBB (high) (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of BBB (high) (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of BBB (low) (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of BBB (low) (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of BB (high) (sf)

Class C Risk Sensitivity:

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

Class D Risk Sensitivity:
-- 25% increase in LGD, expected rating of BB (high) (sf)
-- 50% increase in LGD, expected rating of BB (sf)
-- 25% increase in PD, expected rating of BB (high) (sf)
-- 50% increase in PD, expected rating of B (high) (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating of BB (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating of BB (low) (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating of B (high) (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating of B (high) (sf)

Class E Risk Sensitivity:
-- 25% increase in LGD, expected rating of B (sf)
-- 50% increase in LGD, expected rating below B (sf)
-- 25% increase in PD, expected rating below B (sf)
-- 50% increase in PD, expected rating below B (sf)
-- 25% increase in PD and 25% increase in LGD, expected rating below B (sf)
-- 25% increase in PD and 50% increase in LGD, expected rating below B (sf)
-- 50% increase in PD and 25% increase in LGD, expected rating below B (sf)
-- 50% increase in PD and 50% increase in LGD, expected rating below B (sf)

The rating on the Class F notes would not be affected by any hypothetical increases in the base case PD or LGD.
