DBRS Confirms Ratings on Roundstone Securities No.1 DAC

DBRS Ratings GmbH (DBRS) confirmed its ratings on the bonds issued by Roundstone Securities No.1 DAC (the Issuer) as follows:

-- Class A notes at AAA (sf)
-- Class B notes at AA (high) (sf)
-- Class C notes at AA (sf)
-- Class D notes at A (high) (sf)
-- Class E notes at BBB (sf)

The rating assigned to the Class A notes addresses the timely payment of interest and ultimate payment of principal on or before the final maturity date. The ratings assigned to the Class B, C, D and E notes address the ultimate payment of interest and principal.

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.
-- 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 bankruptcy-remote special-purpose vehicle (SPV) incorporated in Ireland. The issued notes were used to fund the purchase of Irish residential mortgage loans originated by Bank of Scotland plc and secured over properties located in Ireland. Bank of Scotland sold the portfolio in May 2018 to Erimon Home Loans Ireland limited, a bankruptcy-remote SPV wholly owned by Barclays Bank plc.

On 16 September 2019, DBRS transferred the ongoing coverage of the ratings assigned to the Issuer to DBRS Ratings GmbH from DBRS Ratings Limited. The lead analyst responsibilities for this transaction have been transferred to Alfonso Candelas.

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 July 2019, loans that were two- to three-months in arrears represented 0.5% and the 90+ delinquency ratio represented 5.7% of the outstanding portfolio balance, increasing rapidly from closing nine months ago. DBRS continues to monitor the transaction performance closely.

PORTFOLIO ASSUMPTIONS
DBRS conducted a loan-by-loan analysis of the remaining pool of receivables and has updated its base case PD and LGD assumptions to 5.2% and 25.8%, respectively.

CREDIT ENHANCEMENT AND RESERVES
Credit enhancement is provided in the form of subordination junior notes and the general reserve fund. As of the June 2019 payment date, the credit enhancement of the Class A, B, C, D and E notes were 23.9%, 18.1%, 14.1%, 11.8%, 7.8 % respectively, up from 22.3%, 16.8%, 13.0%, 10.8%, and 7.0% respectively at closing.

The transaction benefits from the general reserve fund, which is available to support the Class A to Class E notes. It was funded at closing at 1.5% of the initial balance of the rated notes less the liquidity reserve fund. The liquidity reserve fund is sized at 1.5% of the Class A balance and provides liquidity support to cover revenue shortfalls on senior fees, Class X1 payment and interest on the Class A notes. The notes will additionally be provided with liquidity support from principal receipts, which can be used to cover interest shortfalls on the most-senior class of notes, provided a debit is applied to the principal deficiency ledgers in reverse sequential order. As of the June 2019 payment date, the general reserve fund was at its target level of EUR 8.3 million.

A key structural feature is the provisioning mechanism in the transaction, which is linked to the arrear’s status of a loan besides the usual provisioning based on losses. The degree of provisioning increases with the increase in number of months in arrears status of a loan. This is positive for the transaction as provisioning based on the arrear’s status will trap any excess spread much earlier for a loan, which may ultimately end up in foreclosure.

The Issuer account bank, paying agent and cash manager is Citibank, N.A., London branch (Citibank). Based on DBRS’s private rating of Citibank, the downgrade provisions outlined in the transaction documents, and other mitigating factors inherent in the transaction structure, DBRS considers the risk arising from the exposure to Citibank to be consistent with the rating assigned to the Class A notes, as described in DBRS'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 considered the following stress scenarios as compared with the parameters used to determine the rating (the Base Case):

-- 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.
-- The base case PD and LGD of the current pool of loans for the Issuer are 5.2% and 25.8%, 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 (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 A (high) (sf).

Class A Risk Sensitivity:
-- 25% increase in LGD, expected rating of AA (high) (sf)
