DBRS Morningstar Assigns Provisional Credit Ratings to Dilosk RMBS No. 7 DAC

RMBS

July 11, 2023

DBRS Ratings GmbH (DBRS Morningstar) assigned provisional credit ratings to the residential mortgage-backed notes to be issued by Dilosk RMBS No. 7 DAC (the Issuer) as follows:

-- Class A notes at AAA (sf)
-- Class B notes at AA (low) (sf)
-- Class C notes at A (sf)
-- Class D notes at BBB (sf)
-- Class E notes at BB (sf)
-- Class F notes at B (low) (sf)
-- Class X1 notes at CCC (sf)

The credit rating on the Class A notes addresses the timely payment of interest and the ultimate repayment of principal. The rating on the Class B notes addresses the timely payment of interest once they are the senior most class of notes outstanding and the ultimate repayment of principal on or before the final maturity date. The credit ratings on the Class C, Class D, Class E, Class F, and Class X1 notes address the ultimate payment of interest and principal.

DBRS Morningstar does not rate the Class X2 and Class Z notes also expected to be issued in this transaction.

CREDIT RATING RATIONALE
The Issuer is a bankruptcy-remote special-purpose vehicle incorporated in the Republic of Ireland. The Issuer will use the proceeds of the notes to fund the purchase of prime and performing Irish buy-to-let (BTL) mortgage loans secured over properties located in Ireland. The majority of the mortgage loans included in the portfolio were originated by Dilosk DAC (Dilosk; the originator, seller, and servicer) in the past six years; however, a small subset corresponds with more seasoned loans from a portfolio which Dilosk acquired from the Governor and Company of the Bank of Ireland acquired in 2014.

This is the seventh securitisation from Dilosk, following Dilosk RMBS No. 6 (STS) (Dilosk 6), which closed in April 2023. The initial mortgage portfolio consists of EUR 210 million of first-lien mortgage loans collateralised by BTL residential properties in Ireland. The mortgages were mostly granted between 2017 and 2022, except for the portion corresponding with the previously acquired portfolio.

The mortgage loans will be serviced by BCMGlobal ASI Limited (BCMGlobal), trading as BCMGlobal, in its role as delegated servicer. DBRS Morningstar reviewed both the originator and servicer via an email update in February 2023. Underwriting guidelines are in accordance with market practices observed in Ireland and are subject to the Central Bank of Ireland’s macroprudential mortgage regulations, which specify restrictions on certain lending criteria. CSC Capital Markets (Ireland) Limited will act as the back-up servicer facilitator.

As of 31 March 2023, a large proportion of the loans in the portfolio (55.8% in terms of outstanding balance) repays on an interest-only basis. Only 0.7% of the loans in the mortgage portfolio were in arrears at closing with a portion of 0.3% being more than one month in arrears.

Liquidity in the transaction is provided by the non-amortising general reserve fund (GRF), which the Issuer can use to pay senior costs and interest on the rated notes but also to clear principal deficiency ledger (PDL) balances. Liquidity for the Class A notes will be further supported by a liquidity reserve fund (LRF), fully funded at closing and then amortising in line with the referred class of notes, which shall also feature a floor of 75% of its initial balance at closing. The notes’ terms and conditions allow interest payments, other than on the Class A notes and on the Class B notes when they are the most senior class of notes outstanding, to be deferred if the available funds are insufficient.

Credit enhancement for the Class A notes is calculated at 10.85% and is provided by the subordination of the Class B to Class F notes and the general reserve fund. Credit enhancement for the Class B notes is calculated at 7.85% and is provided by the subordination of the Class C to Class F notes and the general reserve fund. Credit enhancement for the Class C notes is calculated at 4.35% and is provided by the subordination of the Class D to Class F notes and the general reserve fund. Credit enhancement for the Class D notes is calculated at 2.35% and is provided by the subordination of the Class E to Class F notes and the general reserve fund. Credit enhancement for the Class E notes is calculated at 1.10% and is provided by the subordination of the Class F notes and the general reserve fund. Credit enhancement for the Class F notes is calculated at 0.35% and is provided by the general reserve fund.

A key structural feature is the provisioning mechanism in the transaction that is linked to the arrears 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 arrears status traps any excess spread much earlier for a loan that may ultimately end up in foreclosure.

Payments are made directly by the borrowers via direct debit, standing order, or cheque, unless otherwise agreed, into a collection account held at the BNP Paribas, Dublin Branch. The amounts in the collections account will be transferred to the Issuer account at least twice every week. DBRS Morningstar’s private rating on BNP Paribas, Dublin branch in its role as Account Bank is consistent with the threshold for the account bank as outlined in DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology, given the credit ratings assigned to the notes.

DBRS Morningstar based its credit ratings on a review of the following analytical considerations:
-- The transaction capital structure and form and sufficiency of available credit enhancement.
-- The credit quality of the mortgage portfolio and the ability of the servicer to perform collection and resolution activities. DBRS Morningstar calculated probability of default (PD), loss given default (LGD), and expected loss (EL) outputs on the mortgage portfolio. DBRS Morningstar uses the PD, LGD, and ELs as inputs into the cash flow tool. DBRS Morningstar analysed the mortgage portfolio in accordance with DBRS Morningstar’s “European RMBS Insight Methodology: Irish Addendum”.
-- The ability of the transaction to withstand stressed cash flow assumptions and repay the Class A, Class B, Class C, Class D, Class E, Class F, and Class X1 notes according to the terms of the transaction documents. DBRS Morningstar analysed the transaction structure using Intex DealMaker.
-- The sovereign rating of AA (low) with a Stable trend (as of the date of this press release) on the Republic of Ireland.
-- The consistency of the legal structure with DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology and the presence of legal opinions addressing the assignment of the assets to the Issuer.

DBRS Morningstar’s credit rating on Class A, Class B, Class C, Class D, Class E, Class F, and Class X1 notes addresses the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents. The associated financial obligations are listed at the end of this Press Release.

DBRS Morningstar’s credit rating does not address non-payment risk associated with contractual payment obligations contemplated in the applicable transaction document(s) that are not financial obligations.

DBRS Morningstar’s long-term credit ratings provide opinions on risk of default. DBRS Morningstar considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.

ENVIRONMENTAL, SOCIAL, GOVERNANCE CONSIDERATIONS
There were no Environmental/Social/Governance factors that had a significant or relevant effect on the credit analysis.

-- In respect of the Class B notes, a PD of 20.4% and an LGD of 20.5% corresponding to the AA (low) (sf) rating scenario, was stressed assuming a 25% and 50% increase in the PD and LGD.
