DBRS Assigns AA (low) Rating on Bank of Ireland Mortgage Bank Mortgage Covered Securities Programme Series 55

Covered Bonds
June 21, 2016

DBRS Ratings Limited (DBRS) has today assigned a rating of AA (low) to the Series 55 Mortgage Covered Securities (Series 55) issued under the Bank of Ireland Mortgage Bank (BOIMB or the Issuer) EUR 15,000,000,000 Mortgage Covered Securities Programme (the Programme). Series 55 is a EUR 500 million floating-rate bond indexed to Euribor 3 months +0.5% maturing on 21 June 2023. Concurrently, DBRS has discontinued the ratings on Series 32, repaid in full in December 2015 and on Series 4 and 30, repaid in full in February 2016. DBRS has also confirmed the AA (low) ratings on the other outstanding series. Following the issuance of Series 55, there are 38 series of covered bonds outstanding, for a total amount of EUR 7.19 billion.

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

-- A Covered Bonds Attachment Point (CBAP) of “A”, being the Long-Term Critical Obligations Rating of Bank of Ireland. BOI is the Reference Entity for the Programme.
-- A legal and structuring framework (LSF) assessment of Adequate associated with the Programme.
-- A Cover Pool Credit Assessment (CPCA) of BBB (low) being the lowest CPCA in line with the LSF-Implied Likelihood (LSF-L).
-- An LSF-implied likelihood (LSF-L) of A (high).
-- A one-notch uplift for good recovery prospects.
-- A level of overcollateralisation (OC) of 32.0% that DBRS gives credit to, being the minimum observed OC level during the past 12 months adjusted by a scaling factor of 0.85.

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 cover pool (CP).

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 prospects, (5) the relative amortisation of the CB and CP were to move adversely or (6) volatility in the financial markets were to cause the currently estimated market value spreads to be increased.

The total outstanding amount of securities under the Programme after the issuance is EUR 7.19 billion, while the aggregate balance of the CP is EUR 11.96 billion (as of March 2016, including mortgages and substitution assets), resulting in a total OC of 66.5%. Of the Mortgage Covered Securities outstanding, 79.8% pay a fixed coupon. The interest rate mismatch in the Programme is hedged with BOI.

As of the end of March 2016, the CP included EUR 10.95 billion first-lien residential mortgages and EUR 1.02 billion substitution assets. The weighted-average (WA) current loan-to-value (LTV) of the mortgages was 57.14%, while the WA-indexed LTV was 72.68%. The WA seasoning was 9.1 years and the WA remaining term was 18.7 years.
Fixed-rate mortgages in the CP accounted for 12.2% of the balance, while tracker and variable mortgages represented 87.8% of the 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.

All figures are in euros unless otherwise noted.

The principal methodology applicable is “Rating European Covered Bonds” (March 2016). This can be found at http://www.dbrs.com/about/methodologies. In DBRS’s opinion, the changes under consideration do not require the application of the entire principal methodology. Therefore, an asset analysis and an operational risk review were not conducted. A review of the legal documents was limited to the final terms of the new issuance.
