was some three times that of other European banks. Former Labour Party leader Pat Rabbitte called for more competition in the Irish banking sector. In August 2006 the bank again announced record profits for the first half of 2006, making €1.2 billion before tax, equating to €1.2 million per hour. 2008 share price collapse The international credit crunch presented the first challenge to AIB — namely a dramatic fall-off in liquidity. As AIB depends to a significant extent on the international financial markets for liquidity due to an insufficient deposit base, this has impacted the bank severely. The Irish government stepped in with a guarantee which effectively granted a triple A rating on AIB debt, thus freeing up its access to finance. The second and more serious problem, unacknowledged by bank management, the financial regulator and the Irish government, is solvency. The question concerning solvency has arisen due to domestic problems in the crashing Irish property market. AIB, like most Irish financial institutions, has substantial exposure to property developers in their loan portfolio. These property developers are currently suffering from gross over-supply of property, much still unsold, while demand has evaporated. The massive immigration from Eastern Europe which had propped up demand has now reversed due to rapidly rising unemployment in Ireland. Irish property developers own speculated billions of euros of overvalued land parcels such as urban brownfield and greenfield sites, and also agricultural land at an average value of €23,600 per acre (US$32,000 per acre or €60,000 per hectare) which is several multiples above the value of equivalent land in other European countries. AIB correctly identify a systematic risk of triggering an even more severe financial crisis in Ireland if they were to call in the loans as they fall due. The loans are subject to terms and conditions, referred to as "covenants". Although AIB is not one of the banks listed as waiving these covenants, confidence in the Irish banking system is low as a result of other Irish banks electing to waive these financial safeguards in fear of provoking the (inevitable) bankruptcy of many property developers and banks are thought to be "lending some developers further cash to pay their interest bills, which means that they are not classified as 'bad debts' by the banks." Furthermore, AIB's balance sheet indicated only limited impairment (bad debt) provisions. Their 2008 1st half financial report only accounts for an impairment
