DBRS Morningstar Assigns Ratings to Burlington Mortgages No.1 DAC

RMBS
March 16, 2020

DBRS Ratings Limited (DBRS Morningstar) assigned the following ratings to the notes issued by Burlington Mortgages No.1 DAC (the Issuer):

-- Class A1 Notes rated AAA (sf)
-- Class A2 Notes rated AAA (sf)
-- Class B Notes rated AA (low) (sf)
-- Class C Notes rated A (low) (sf)
-- Class D Notes rated BBB (low) (sf)
-- Class E Notes rated BB (sf)
-- Class Z Notes not rated

The ratings on the Class A1 and A2 notes address the timely payment of interest and ultimate repayment of principal on or before the final maturity date in 2058. The ratings on the Classes B, C, D, and E notes address the timely payment of interest once most senior and the ultimate repayment of principal on or before the final maturity date.

Burlington Mortgages No.1 DAC (the Issuer or Burlington) is a securitisation collateralised by a portfolio of owner-occupied (OO) residential mortgage loans granted by EBS DAC (EBS) and its fully-owned subsidiary, Haven Mortgages Limited (Haven) in Ireland. Both originators – which are also the sellers in the transaction – are part of the Allied Irish Bank (AIB) banking group.

The Issuer issued seven tranches of collateralised mortgage-backed securities to finance the purchase of the mortgage portfolio. The general reserve fund and Class A liquidity reserve fund, which provide liquidity support and credit enhancement to the transaction, was fully funded at closing through subordinated loans provided by the two sellers.

The two sellers act as servicers of the transaction and will retain at least 5% of each class of the notes, in accordance with European Union securitisation regulations.

As of 29 February 2020, the initial portfolio consisted of 24,950 loans extended to 23,189 borrowers with an aggregate principal balance of EUR 4,026 million. EBS originated the majority of the loans (65.1%) with Haven originating the rest (34.9%). The portfolio excludes all loans that have either been restructured or been in arrears during at any point during the life of the mortgages so far. The weighted-average (WA) seasoning of the portfolio is 5.5 years as about one quarter of the pool was originated before 2010.

The transaction portfolio comprises both recent originations (59.9% comprise loans originated after 2015) and loans originated before 2010 and the sovereign debt crisis (25.8%), which drives up the indexed current loan-to-value as the properties backing pre-2010 loans were bought at the peak of the market. The WA seasoning of the pool is 5.5 years and the WA remaining term is 22.8 years. There is no concentration in the maturity profile of the portfolio. There are no mortgages that are in arrears or have been in arrears over the course of their life.

The origination quality of the pool is strong across vintages because of the borrowers’ prime features (95% full-time employees, and virtually 100% purchase purpose) and the prudent lending decisions underpinned by full valuation reports and a WA original loan-to-value of 79.4%.

The transaction benefits from an initial portfolio all-in rate of 3.0% whereas the WA cost of funding is only 0.25% initially but is expected to increase due to sequential amortisation and margin step-ups on several notes, including the Class A1 Notes. However, the transaction does not include any covenant on the minimum standard variable rate (SVR) to be paid by the portfolio, and there is no swap in place to hedge against the SVR compression over the life of the transaction. Therefore, portfolio margins may be compressed in an increasing rate scenario as, historically, lenders’ margins go down as monetary rates climb but also do so in a stable rating scenario due to the changes in the lenders’ competitive landscape.

The notes are paid down sequentially on a monthly basis, which allows credit enhancement for the more senior notes to build up over time as the notes amortise. The Class A1 and A2 notes pay interest pari passu and pro rata but the Class A2 Notes are time-subordinated to the Class A1 Notes since the Class A1 Notes amortise principal in priority to the Class A2 Notes until full redemption of the Class A1 Notes.

The transaction benefits from both a funded liquidity reserve to cover Class A1 and A2 interest shortfalls and a funded general reserve to cover interest and principal shortfalls on the rated notes. Moreover, principal can be drawn to cover interest on the most senior notes outstanding, thus further decreasing the risk of a default on the timely interest payment of the rated notes.

DBRS Morningstar based its ratings on the following analytical considerations:
--The transaction capital structure, and form and sufficiency of available credit enhancement to support DBRS Morningstar-projected expected cumulative losses under various stressed scenarios.
--The credit quality of the portfolio and DBRS Morningstar’s qualitative assessment of the originators’ capabilities with regard to originations, underwriting, and servicing.
--The transaction’s ability to withstand stressed cash flow assumptions and repay the noteholders according to the terms and conditions of the notes. The ratings on the Class A1 and A2 notes address the timely payment of interest and ultimate repayment of principal on or before the final maturity date. The ratings on the Class B, C, D, and E notes address the timely payment of interest once most senior and the ultimate repayment of principal on or before the final maturity date.
--The transaction parties’ financial strength in order to fulfil their respective roles.
--The transaction’s legal structure and its consistency with DBRS Morningstar’s “Legal Criteria for European Structured Finance Transactions” methodology, as well as the presence of the appropriate legal opinions that address the assignment of the assets to the Issuer.
--The sovereign rating of the Republic of Ireland at A (high) with a Positive trend as of the date of this press release.

DBRS Morningstar analysed its transaction structure in Intex DealMaker, considering the default rates at which the rated notes did not return all specified cash flows.

The following scenarios constitute the parameters used to determining the ratings (the Base Case):
-- In respect of the Class A1 and A2 Notes, the probability of default (PD) and loss given default (LGD) at the AAA (sf) stress scenario of 23.9% and 59.8%, respectively.
-- In respect of the Class B Notes, the PD and LGD at the AA (low) (sf) stress scenario of 14.1% and 45.7%, respectively.
-- In respect of the Class C Notes, the PD and LGD at the A (low) (sf) stress scenario of 10.0% and 39.6%, respectively.
-- In respect of the Class D Notes, the PD and LGD at the BBB (low) (sf) stress scenario of 5.9% and 29.0%, respectively.
