The Company’s 2011 fourth quarter results included losses for current year catastrophic events of $70.8 million, net of reinsurance and reinstatement premiums. Such amount included $60.6 million from the severe flooding in Thailand and $5.4 million from an Australian hailstorm in the 2011 fourth quarter, with the remainder due to net increases in loss estimates from other catastrophic events. The Company’s estimates for these events are based on currently available information derived from modeling techniques, industry assessments of exposure, preliminary claims information obtained from the Company’s clients and brokers to date and a review of in-force contracts. The severe flooding in Thailand spanned several months between July and December 2011 and has had a significant impact on the Thai economy. Due to the size, duration and complexity of the event, substantial uncertainty remains regarding total covered losses for the insurance industry and the assumptions underlying the Company’s estimates. Actual losses will depend to a great extent on claims from contingent business interruption coverage. The Company’s actual losses from catastrophic events may vary materially from the estimates due to the inherent uncertainties in making such determinations resulting from several factors, including the preliminary nature of available information, the potential inaccuracies and inadequacies in the data provided by clients and brokers, the modeling techniques and the application of such techniques, the contingent nature of business interruption exposures, the effects of any resultant demand surge on claims activity and attendant coverage issues. In addition, actual 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.
