Over half the litigation liabilities of the FTSE 100 are accounted for by UK banks, according to research from Thompson Reuters. The company reported that the FTSE 100 set aside £26.2bn during 2016 to tackle litigation and regulatory investigation expenses. Over half, £14.6bn, was attributed to Barclays, HSBC, Lloyds Banking Group and Royal Bank of Scotland (RBS). However this is down on 2015, when FTSE 100 litigation provisions hit a record £31.1bn, with money set aside by banks also hitting a record £17.3bn. Oil and gas producers accounted for over £5 billion, 19 per cent of the FTSE 100 total. However the biggest rise in contribution came from the pharmaceutical sector, which has more than doubled in a year from £612m in 2015 to £1bn in 2016.
