Insurer Aviva PLC (LON:AV.) forecast no major hit from last week's EU referendum result but said the consequences would take years to resolve.
Aviva said its analysis of the vote to leave the EU had shown it would have no significant operational impact on the company.
The group said its capital position was resilient to market stress and it estimated that on Friday last week, its Solvency II coverage ratio remained close to the top of its working range of 150% - 180%.
At its 2015 full-year results in March 2016, Aviva reported a Solvency II ratio of 180% and a surplus of £9.7bn.
The group said it had "one of the strongest and most resilient balance sheets in UK insurance with low sensitivity to market stress and over the last four years Aviva has tripled its economic capital surplus.
"Aviva will continue to monitor the technical implications of the vote to leave, which will only be resolved after several years of negotiating a new relationship between the UK and the EU," it said in a statement.
Shares in Aviva fell 2.06p to 372.19p in early London trading.
