Barclays' (BCS) Q4 net losses rose to £514M ($843.9M) from £364M a year earlier, partly due to increased restructuring costs, a higher levy related to riskier financing, and a £331M charge for litigation and regulatory penalties.
Adjusted pretax profit dropped to £191M from £1.4B.
The investment bank swung to a pretax loss of £329M from a profit of £760M a year earlier, with the division's performance hurt by higher operating costs, a decline in its fixed-income business and £87M in restructuring costs.
The retail bank's pretax profit dropped to £212M from £275M; Q4 2013 included £119M in restructuring expenses.
Barclays' Tier 1 capital ratio rose to 13.2% by the end of 2013 from 10.8% in 2012.
