G4S boss Nick Buckles 'could quit' over London 2012 Olympics fiasco Mr Buckles, who earns a base salary of £830,000 a year, said the financial impact of the crisis will mean he will not take a bonus this year. "I honestly believe most CEOs going forward will have a reason why they can't take their bonus," he stated. It will be the second year in succession that Mr Buckles has not taken a bonus. Last year G4S was forced to scrap a £5.2bn takeover of ISS after opposition from shareholders, costing it £55m in fees. Peter Lees, head of equities at F&C Investments, which owns 0.5pc of G4S, said: "It is too early to say what should happen to Nick Buckles. We need to see in detail what went wrong first. We supported Mr Buckles through one fiasco but there are only so many fiascos you can have. G4S has pledged to conduct an internal review into the failings of the Olympic contract after London 2012. Mr Buckles said the company had "underestimated the challenge" of finding 10,000 staff and took responsibility for the shortfall. However, he said there were "mitigating circumstances" such as the organisers of London 2012, Locog, being late in providing the final details of the day-by-day security requirements for the Olympics. Grahame Gibson, the chief operating office of G4S and a member of the board, raised £280,000 by selling 100,000 shares in the company on June 19, two weeks before the Olympic crisis was reported to Mr Buckles. A spokesman for G4S said the share sale was for "personal reasons" and that Mr Gibson, who is the head of G4S's Americas business and based in the US, was not involved in the Olympic operations.
