Barclays on Thursday reported a fresh £500 million ($800 million) legal provision related to investigations into the alleged manipulation of the foreign-exchange market.

The charge weighed down what was otherwise a brighter quarterly performance by the British bank. After stripping out the charge and other one-off items, Barclays posted a better-than-expected adjusted third-quarter pretax profit of £1.59 billion, 15% higher than last year's £1.39 billion and beating analyst expectations of around £1.21 billion because of lower-than-expected restructuring costs in the three-month period.
