HAMILTON, Bermuda, Dec. 12, 2012 /PRNewswire/ -- Platinum Underwriters Holdings, Ltd. (NYSE: PTP) today announced that it expects Hurricane Sandy will have a net negative impact of approximately $30 million on the Company's results for the quarter ended December 31, 2012.  The net negative impact from Hurricane Sandy includes a preliminary estimate of losses and loss adjustment expenses, net of retrocessional coverage, reinstatement premiums and income taxes. 

The estimated net negative impact from Hurricane Sandy is generally based on a review of the Company's in-force contracts and claims information and analysis received from brokers and cedants as well as the Company's portfolio modeling and market share analysis.

The Company's assessment of its exposure to this event is ongoing.  The actual net negative impact of this event on the Company's results may differ materially from the Company's estimate due to the inherent uncertainties of making such estimates, including the preliminary nature of available information, uncertainties in loss development patterns, the use of portfolio models in the estimation process and potential inaccuracies and inadequacies in data provided by clients and brokers.
