State-backed Royal Bank of Scotland
RBS said on Thursday it also set aside 459 million in the second quarter to deal with conduct and litigation issues.
The bank made an attributable profit of 293 million pounds ($457 million), up 27% on the same period last year. Analysts had expected a loss of 260 million pounds, according forecasts provided by the bank.
RBS said it planned to return capital to shareholders by paying dividends or buying back shares, but said it would not be in a position to do so until the first quarter of 2017 at the earliest.
The bank, which is 78%-owned by the British government, said it would run down its 'bad bank' called RBS Capital Resolution (RCR) before the end of 2015, a year ahead of schedule.
RBS said its restructuring costs in the quarter more than doubled from 453 million pounds in the first quarter "as the pace of restructuring accelerated."
