The objective of ASU 2014-08 is to improve the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. ASU 2014-08 will also require expanded disclosures for discontinued operations and require an entity to disclose the pretax profit or loss of an individually significant component of an entity that does not qualify for discontinued operations reporting. ASU 2014-08 is prospectively effective for public business entities in annual periods beginning on or after December 15, 2014, and interim periods beginning on or after December 15, 2015. Entities may early adopt ASU 2014-08 for new disposals that have not been reported in the consolidated financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this guidance; however, it is not expected to have a material impact on the Company</font><font style="font-family:inherit;font-size:10pt;">’</font><font style="font-family:Arial;font-size:10pt;">s consolidated statements of operations and financial position.</font></div></div>

Actual results could differ materially from those estimates. The major estimates reflected in the Company’s consolidated financial statements include, but are not limited to, the reserve for claims and claim expenses; reinsurance recoverables, including allowances for reinsurance recoverables deemed uncollectible; estimates of written and earned premiums; fair value, including the fair value of investments, financial instruments and derivatives; impairment charges and the Company’s deferred tax valuation allowance.</font></div></div>
