ASU 2010-26 modifies the definition of the types of costs that can be capitalized in relation to the acquisition of new and renewal insurance contracts. The amended guidance requires costs to be incremental or directly related to the successful acquisition of new or renewal contracts in order to be capitalized as a deferred acquisition cost. Capitalized costs would include incremental direct costs, such as commissions paid to brokers. Additionally, the portion of employee salaries and benefits directly related to time spent for acquired contracts would be capitalized. Costs that fall outside the revised definition must be expensed when incurred. ASU 2010-26 will be effective for fiscal periods beginning on or after December 15, 2011 with prospective or retroactive application permitted.

ASU 2011-04 does not extend the use of fair value but, rather, provides guidance about how fair value should be applied where it is already required or permitted under GAAP and requires enhanced disclosures covering all transfers between Levels 1 and 2 of the fair value hierarchy. Additional disclosures covering Level 3 assets are also required. ASU 2011-04 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011.

ASU 2011-05 requires that all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements.

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 net deferred tax asset.</font></div></div>
