XL Group CEO Mike McGavick said that XL’s fourth quarter results demonstrated progress in several key elements driving shareholder value. The P&C operations’ 91.4% combined ratio benefited from outstanding performance from the reinsurance segment, positive prior year development and sustained operating efficiency.

"We received our license to offer insurance in China and added experienced teams in lines we believe offer prospects for strategic growth.

"Our on-going risk management discipline resulted in our catastrophe losses being at the low end of the expected range, with only modest changes to our initial estimates for the New Zealand earthquake.

"We reduced exposures to non-core holdings, and we continued to return excess capital through share buybacks. We believe XL is in a solid position to meet the challenges of current market conditions and the opportunities that will come as conditions improve," McGavick said.
