In particular, estimates of unpaid losses and loss adjustment expenses and related reinsurance recoverable on unpaid losses are subject to considerable estimation error due to the inherent uncertainty in projecting ultimate claim costs. In addition, estimates and assumptions associated with the amortization of deferred charges on retroactive reinsurance contracts, determinations of fair values of certain financial instruments and evaluations of goodwill and identifiable intangible assets for impairment require considerable judgment. Actual results may differ from the estimates used in preparing our Consolidated Financial Statements.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9pt; MARGIN-TOP: 0pt">  </p> </div> | |
