Use Of Estimates

<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:20px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;">Estimates</font><font style="font-family:inherit;font-size:10pt;"> — The preparation of U.S. GAAP Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. The significant estimates include, but are not limited to, reserve for loss and loss adjustment expenses ("loss and LAE"); recoverability of deferred commission and other acquisition expenses; determination of impairment of goodwill and other intangible assets; valuation of financial instruments; and determination of other-than-temporary impairment ("OTTI") of investments.
