The insurer said CEO Philip Smith, Chief Financial Officer Rory O'Connor and Peter Burke, a claims director, had been suspended.
It said no findings had been made against any individuals at this time, but as a result of these issues it estimated that its 2013 operating result would be 70 million pounds ($112 million) lower than current market expectations.
