RenaissanceRe yesterday announced that its preliminary estimated impact from Superstorm Sandy is approximately $130 million.The negative impact to the Bermuda-based reinsurer’s fourth quarter includes the sum of estimates of net claims and claim expenses incurred, earned reinstatement premiums assumed and ceded, lost profit commissions, redeemable noncontrolling interest — DaVinciRe, and other income in respect of ceded reinsurance contracts accounted for at fair value.The company says its estimates are based on a review of its potential exposures, preliminary discussions with certain counterparties and catastrophe modelling techniques.“Given the magnitude and recent occurrence of Storm Sandy, relatively limited claims data received to date, the contingent nature of business interruption and other exposures, the unusual complexity of the coverage and legal issues relating to Storm Sandy, and the other uncertainties inherent in loss estimation, meaningful additional uncertainty remains regarding total covered losses for the insurance industry from Storm Sandy and accordingly, the company’s estimate is subject to change as new or revised data is received from the company’s counterparties, and other factors,” a statement from RenRe said.Accordingly, the company’s actual net negative impact from Storm Sandy will vary from this preliminary estimate, perhaps materially so.
