A partner in PricewaterhouseCopper (PwC) has said he stands over past audits of Irish banks.
The role of external auditors in the lead-up to and during the financial crisis is being scrutinised by the banking inquiry today.
PwC senior partner Ronan Murphy told the committee that it was up to individual banks to set the loan loss provisions and that it was not the responsibility of PwC as auditors to choose regulations and how they should be applied.
He added PwC stood over the quality of audits of the financial statements of Bank of Ireland, AIB and Bank of Scotland Ireland.
