TEXT-Fitch affirms AIB Mortgage Bank's covered bonds at 'A'

(The following statement was released by the rating agency)

Oct 2 - Fitch Ratings has affirmed AIB Mortgage Bank's (AIBMB) mortgage covered securities (MCS) at 'A' with a Negative Outlook following a review of the programme.

The total outstanding MCS equates to EUR11.19bn and all benefit from a 12-month extendable maturity from their expected maturity dates. AIBMB is a wholly-owned subsidiary of AIB Bank plc (AIB; 'BBB'/Negative/'F2') and a member of the AIB Group.

The MCS's rating is based on AIB's Long-term Issuer Default Rating (IDR) of 'BBB' and a D-Cap of 1 (very high) and the overcollateralisation (OC) that Fitch takes into account in it analysis, the combination of which enables the MCS to be rated as high as 'BBB+' on a probability of default (PD) basis. As AIB is rated 'F2' Fitch only gives credit to the voluntary public commitment in place which currently stands at 52%. AIBMB confirmed to Fitch that they shortly intend to increase the publicly committed level of OC to at least 54.2%. This is sufficient to pass 'BBB+' stress scenarios, and provides for high recoveries given default of the covered bonds in a 'A' scenario.

The D-Cap of 1 is driven by the very high risk assessment of the liquidity gap & systemic risk component, which is the weakest of the D-Cap components. The cover pool-specific component is assessed as moderate and the systemic alternative management component is assessed as very low risk from a discontinuity point of view. The asset segregation and privileged derivative are assessed as low (see "Fitch Puts 2 Dutch Covered Bonds on RWN; Assigns Dutch & Irish Programmes D-Caps & Outlooks" dated 12 September 2012 at


The very high risk assessment of liquidity gap and systemic risk is due to the Irish sovereign rating of 'BBB+' and the concerns over the ability to liquidate the pool in a timely manner if needed post issuer default. It also incorporates a three-month interest reserve that protects against liquidity gaps following issuer insolvency and a 12-month extendible maturity on the MCS. The asset segregation of the cover pool for Irish programmes benefits from the strong provisions of the Irish ACS Act. The D-Cap also assesses the role of the National Treasury Management Association, having the obligation to step in and manage cover pools where an alternative manager cannot be found post issuer default and the adequate IT systems and processes in place to provide timely delivery of data.

The OC supporting the current 'BBB+' rating on a probability of default (PD) basis and 'A' incorporating recoveries, given default of the MCS, has increased to 54.2% from 52.2% in May 2012. The main drivers for the increase of the OC were, the update of Fitch's modelling assumptions for Ireland earlier this year (see 'EMEA Criteria Addendum - Ireland' dated 01 August 2012 on

). Fitch also updated its refinancing spreads assumptions for Ireland since the last review and these have been applied in the cashflow model. Finally, the results were also driven by the asset and liability mismatches and the bonds' weighted average swap margin, which increased due to some bond redemptions.

At end-June 2012, the cover pool consisted of EUR17.8bn of residential mortgage loans and EUR75m of substitution assets held in accounts with AIB and Barclays Bank plc ('A'/Stable/'F1'). The pool consisted of 126,212 loans secured on residential properties in Ireland with 9.8% on interest only repayments and 21% buy-to-let loans. The mortgage portfolio had a weighted average (WA) original loan-to-value ratio (LTV) of 75.1% and a WA current indexed LTV of 106%. The cover pool assets are diversified over Ireland, with the highest concentrations in Dublin (37%). In a 'AA' scenario, Fitch has calculated the pool's cumulative WA frequency of foreclosure at 35.6% and a WA recovery rate of 36.5%.

Fitch will monitor the key characteristics of the cover assets and outstanding covered bonds on an on-going basis, and check whether the OC taken into account in its analysis provides protection commensurate with the rating. The level of OC supporting the rating is affected by, among other factors, the profile of the cover assets relative to outstanding covered bonds, which can change over time, even in the absence of new issuances. Therefore, it cannot be assumed that the rating will remain stable over time.
