Ulster Bank is putting aside €35m for costs arising from its recent technology glitch which affected its customers for several weeks in June and July.
The bank said that given the scale of the impact on its customers, it expects there will be additional costs over the coming months as it continues “the process of putting things right”.
It reported an operating loss of £555m for the first six months of the year, compared to £543m for the same period last year.
The bank said it continued to see elevated levels of arrears as the market remains challenging.
Its parent bank, Royal Bank of Scotland, reported a pre-tax loss of £1.5bn for the six months to the end of June, compared to a loss of £794m last year.
It said the IT meltdown has cost it £125m.
Ulster Bank said this morning it had already started to correct and reverse fees and charges to customers affected by this issue.
The bank said it was continuing to work through the details of how it will address out-of-pocket expenses and recognition of the inconvenience caused.
It said it would provide details to customers as soon as possible.
The Financial Ombudsman has said his office received about 150 complaints during July relating to the Ulster Bank IT problems.
Bill Prasifka said the issues have been referred back to Ulster Bank, and he is encouraging the bank to do everything it can to settle the actions.
On RTÉ's News at One, Mr Prasifka said no overall compensation package can deal with every case, and there will be some exceptional cases that will have to be dealt with separately.
He encouraged consumers to work with Ulster Bank on their issues, and not to feel rushed, because they have up to six years to make a complaint if they are not happy with the bank's response.
Mr Prasifka called for an industry-wide response from the financial sector, because many providers will have been affected by problems at Ulster Bank.
