Aspen Insurance Holdings Limited (“Aspen”) (NYSE: AHL) announced today an initial estimate of catastrophe losses from Superstorm Sandy. Aspen expects fourth quarter 2012 earnings to include approximately $175 million after-tax, and net of reinsurance and reinstatement premiums related to the storm. The losses from the storm are currently estimated to arise approximately 65% in our reinsurance segment and 35% in our insurance segment. Aspen’s estimate is based on its review of the individual treaties and policies expected to be impacted, and discussions with clients and brokers. In making this initial estimate, Aspen also has taken into account a combination of provisional loss advices, limited client loss data and modeled loss projections . Given the complexity of this event, there is considerable uncertainty associated with this estimate and actual losses may differ materially. Aspen intends to resume repurchases of its ordinary shares shortly under the existing buyback authorization, consistent with its capital management strategy.
