DBRS Assigns AA (low) Rating to Bank of Ireland Mortgage Bank Mortgage Covered Securities Programme Series 53

DBRS Ratings Limited (DBRS) has today assigned a rating of AA (low) to the Series 53 Mortgage Covered Securities (Series 53) issued under the Bank of Ireland Mortgage Bank (BOIMB or the Issuer) EUR 15,000,000,000 Mortgage Covered Securities Programme (the Programme). Series 53 is a EUR 15 million fixed-rate bond maturing on 10 December 2040. There are EUR 8.54 billion CB outstanding under the Programme, including Series 53.

The AA (low) rating assigned reflects the following analytical considerations:

-- A Covered Bonds Attachment Point (CBAP) of “A”. BOI is the Reference Entity for the Programme. The Programme’s issuer, Bank of Ireland Mortgage Bank, is a wholly owned subsidiary of BOI.
-- A legal and structuring framework (LSF) assessment of Adequate associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB (low), being the minimum CPCA given the CBAP and the rating achievable on the CB.
-- An LSF-implied likelihood (LSF-L) of A (high).
-- A one-notch uplift for good recovery prospect.
-- A level of overcollateralisation (OC) of 21.17% that DBRS gives credit to, being the lowest observed OC level during the past 12 months (24.90%) adjusted by a scaling factor of 0.85.
-- The Issuer’s capabilities with respect to origination of the cover pool (CP) and servicing of the CP.

The transaction was modelled using the DBRS European Covered Bond Cash Flow Model. The main assumptions focused on the timing of defaults, recoveries of the assets, interest rate stresses and market value spreads to calculate liquidation values on the CP.

Following a wind-down cash flow simulation aimed at covering the cost of funding under a stress scenario, which yielded good recovery prospects, DBRS granted a one-notch uplift from the LSF-L.

DBRS has assessed the LSF related to the Programme as Adequate, according to its rating methodology. For more information, please refer to DBRS commentaries “DBRS Assigns LSF Assessment to Irish Covered Bonds” and “Irish Covered Bonds: Legal and Structuring Framework Review,” both available at www.dbrs.com.

Everything else being equal, a downgrade of the CBAP by one notch would lead to a downgrade of the covered bonds rating by one notch. In addition, the ratings of the Programme would be downgraded if any of the following occurred: (1) the CPCA were downgraded below BBB (low), (2) the sovereign rating of the Republic of Ireland was downgraded below the CBAP, (3) the LSF Assessment associated with the Programme were downgraded; (4) the quality and consistency of the CP were no longer sufficient to support a one-notch uplift for good recovery prospect or (5) volatility in the financial markets caused the currently estimated market value spreads to increase.

The total outstanding amount of securities under the Programme is EUR 8.54 billion. Of the Mortgage Covered Securities outstanding, 66.5% pay a fixed coupon. The interest rate mismatch in the Programme is hedged with BOI.

As of the end of September 2015, the CP included EUR 11.47 billion residential mortgages and EUR 1.316 billion substitution assets. The weighted-average (WA) current loan-to-value (LTV) of the mortgages was 57.91%, while the WA-indexed LTV was 76.37%. Buy-to-let mortgages represented 18.60% of the CP. Fixed-rate mortgages in the CP accounted for 9.93% of the balance, while tracker and variable mortgages represented 90.07% of CP balance. All CP assets and all Mortgage Covered Securities are denominated in euros. As such, investors are not currently exposed to any foreign exchange risk.

Notes:
All figures are in euros unless otherwise noted.
