The report said the “Company’s 2012 fourth quarter results included losses for Superstorm Sandy of $203.5 million, net of reinsurance and the effects of reinstatement premiums. Due to the unusual nature of the event, including its broad scope, the number of insureds affected, the complexity of issues contributing to the losses and the preliminary nature of available information, there is substantial uncertainty regarding the assumptions underlying the Company’s losses relating to the event. The Company’s ultimate losses from the storm may vary materially from the current estimates due to these and other factors. In addition, ultimate losses may increase if the Company’s reinsurers fail to meet their obligations to the Company or the reinsurance protections purchased by the Company are exhausted or are otherwise unavailable.”
