Allied Irish Banks plc - July 2010 Stress Test Results

 ·     Allied Irish Banks plc (AIB) was subject to the 2010 EU-wide stress testing exercise coordinated by the Committee of European Banking Supervisors (CEBS), in cooperation with the European Central Bank (ECB), and under the supervision of The Central Bank and Financial Regulator. AIB acknowledges the outcomes of the EU-wide stress tests.

 ·     This stress test complements the risk management procedures and regular stress testing programmes set up in AIB under the Pillar 2 framework of the Basel II, CRD[1] requirements and the  'Implementation of the CRD, 28 December 2008'.  It was also additional to the Central Bank and Financial Regulator's Prudential Capital Assessment Review (PCAR), the results of which were announced on 30 March 2010[2].

 ·     The exercise was conducted using the scenarios, methodology and key assumptions provided by CEBS (see the aggregate report published on the CEBS website[3]). As a result of the assumed shock under the adverse scenario, the estimated consolidated Tier 1 capital ratio would change to 7.2% in 2011 compared to 7.0% as of end of 2009. An additional sovereign risk scenario would have a further impact of 0.70 of a percentage point on the estimated Tier 1 capital ratio, bringing it to 6.5% at the end of 2011, compared with the CRD regulatory minimum of 4%.

 ·     The results of the stress suggest a buffer of 352 EUR mln of the Tier 1 capital would exist at 31 December 2011 against the threshold of 6% of Tier 1 capital adequacy ratio agreed exclusively for the purposes of this exercise. This threshold should by no means be interpreted as a regulatory minimum (the regulatory minimum for the Tier 1 capital ratio is set to 4%), nor as a capital target reflecting the risk profile of the institution determined as a result of the supervisory review process in Pillar 2 of the CRD.

 ·     AIB has held discussions of the results of the stress test with its supervisor the Central Bank and Financial Regulator. To be clear AIB's capital requirements resulting from the PCAR announced on 30 March 2010 were:     (1) An additional ?7.396bn of equity capital to meet the base case target of 7% equity, before taking account of projected asset disposals, and     (2) ?4.865bn of Core Tier 1 capital, less any equity generated under paragraph 1 excluding conversion of preference shares held by the Government, to meet the base case target of 8% Core Tier 1.  This additional Core Tier 1 capital will also satisfy AIB's stress case target of 4% Core Tier 1.

    AIB submitted its capital plan to the Central Bank and Financial Regulator by the 30 April 2010, as required under the PCAR, which details AIB's plans to raise the PCAR capital requirements by the 31 December 2010, as required, through a combination of equity raising and asset disposals.

 ·     The stress test was carried out under a number of key common simplifying assumptions (e.g. constant balance sheet, uniform treatment of securitisation exposures). Therefore, the information should in no way be construed as a forecast nor should it be taken as an update to capital plans. Consequently the numbers below may differ from numbers published previously by AIB. In addition, where the information does not reconcile to previously published information (e.g. annual statements or capital plans), this is a result of supervisory adjustments applied as part of the methodology of the stress test. In the interpretation of the outcome of the exercise, it is imperative to differentiate between the results obtained under the different scenarios developed for the purposes of the EU-wide exercise. The results of the adverse scenario should not be considered as representative of the current situation or possible present capital needs. A stress testing exercise does not provide forecasts of expected outcomes since the adverse scenarios are designed as "what-if" scenarios including plausible but extreme assumptions, which are therefore not very likely to materialise. Different stresses may produce different outcomes depending on the circumstances of each institution.
