Recent accounting pronouncements	2. Significant Accounting Policies Recent Accounting Pronouncements In October 2010, the FASB issued an accounting standards update to address disparities in practice regarding the interpretation of which costs relating to the acquisition of new and renewal insurance contracts qualify for deferral. The provisions of the guidance specify that only costs that are related directly to the successful acquisition of new and renewal insurance contracts may be capitalized. These include incremental direct costs of contract acquisition and certain other costs related directly to underwriting activities. Incremental direct costs of contract acquisition are those that result directly from and are essential to a contract transaction, and would not have been incurred by the insurance entity had the transaction not occurred. Administrative costs, rent, depreciation, occupancy, equipment and all other general overhead costs are considered indirect costs and should be charged to expense as incurred. On January 1, 2012, the Company adopted this guidance on a retrospective basis for all fiscal years presented, and interim periods within those years. The impact of adoption was a reduction in deferred acquisition costs of approximately $21 million, a reduction in deferred tax liabilities of approximately $7 million, and a corresponding reduction in opening retained earnings of approximately $14 million within the Company's December 31, 2011 balance sheet. The adoption of this guidance did not have an impact on the Company's consolidated statements of income or comprehensive income. In May 2011, the FASB issued an accounting standards update to amend existing requirements for fair value measurements and disclosures. The guidance expands the disclosure requirements around fair value measurements categorized in Level 3 of the fair value hierarchy, requiring quantitative and qualitative information to be disclosed related to: (1) the valuation processes used, (2) the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs, and (3) use of a nonfinancial asset in a way that differs from the asset's highest and best use. The guidance requires disclosure of the level in the fair value hierarchy of items that are not measured at fair value, but whose fair value must be disclosed. It also clarifies and expands upon existing requirements for fair value measurements of financial assets and liabilities, as well as instruments classified in shareholders' equity. The Company has adopted this guidance from January 1, 2012; however, it impacted disclosure only and did not have an impact on the Company's financial condition or results of operations. See Note 3, “Fair Value Measurements,” for these updated disclosures. In June 2011, the FASB issued an accounting standards update concerning the presentation of comprehensive income in financial statements. This guidance allows an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under both options, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This guidance eliminates the option to present the components of other comprehensive income only as part of the statement of changes in shareholders' equity. The guidance does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. However, a separate accounting standards update issued in December 2011deferred indefinitely a provision within the original standard requiring entities to present components of reclassifications of other comprehensive income on the face of the income statement. The Company adopted the guidance from January 1, 2012; however, it did not have an impact on the Company's disclosure, financial condition or results of operations or cash flows. In September 2011, the FASB issued an accounting standards update to simplify how entities test goodwill for impairment, by allowing an entity the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting entity is less than its carrying amount, as a basis for determining whether it is necessary to perform the two-step goodwill impairment test required in FASB Accounting Standards Codification Topic 350. After assessing the circumstances that should be considered in making the qualitative assessment, if an entity determines that the fair value of a reporting unit as compared to its carrying value meets the threshold, then performing the two-step impairment step is unnecessary. In other circumstances, performance of the two-step test is required. The guidance also eliminates the option for an entity to carry forward its detailed calculation of a reporting unit's fair value in certain situations. The amendments do not change the current guidance for testing other indefinite-lived intangible assets for impairment. The Company adopted this guidance from January 1, 2012. It did not have an impact on the Company's consolidated financial condition or results of operations or cash flows. In December 2011, the FASB issued new guidance requiring additional disclosures about financial instruments and derivative instruments that are either: (1) offset for balance sheet presentation purposes or (2) subject to an enforceable master netting arrangement or similar arrangement, regardless of whether they are offset for balance sheet presentation purposes. This guidance will be effective on January 1, 2013, with retrospective presentation of the new disclosures required. As this new guidance is disclosure-related only and does not amend the existing balance sheet offsetting guidance, the adoption of this guidance will not impact the Company's financial condition or results of operations or cash flows. .
