Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards Changes to the general accounting principles are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates to the FASB Accounting Standards Codification™. Accounting standards updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s consolidated financial statements. Adoption of New Accounting Standards Basis of Presentation In December 2011, the FASB amended the general accounting principles for Balance Sheet as it relates to the disclosures about offsetting assets and liabilities. The amendment requires disclosures about the Company’s rights of offset and related arrangements associated with its financial instruments and derivative instruments. This amendment also requires the disclosure of both gross and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB amended the general accounting principles for Balance Sheet as it relates to the disclosures about offsetting assets and liabilities. This amendment clarifies that the scope of the Balance Sheet amendment made in December 2011 applies only to derivatives, including bifurcated embedded derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions that are either offset or subject to an enforceable master netting agreement or a similar agreement. These amendments are effective for interim and annual reporting periods beginning on or after January 1, 2013. The Company adopted these amendments and the required disclosures are provided in Note 5 — “Derivative Instruments”. Transfers and Servicing In April 2011, the FASB amended the general accounting principles for Transfers and Servicing as it relates to the reconsideration of effective control for repurchase agreements. This amendment removes from the assessment of effective control the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets and also removes the collateral maintenance implementation guidance related to that criterion. The amendment is effective for interim and annual periods beginning after December 15, 2011. The adoption of this amendment did not have an impact on the Company’s condensed consolidated financial statements. Fair Value Measurements and Disclosures In May 2011, the FASB amended the general accounting principles for Fair Value Measurements and Disclosures as it relates to the measurement and disclosure requirements about fair value measurements. This amendment clarifies the FASB’s intent about the application of existing fair value measurement requirements. It also changes particular principles and requirements for measuring fair value and for disclosing information about fair value measurements. The amendment is effective for interim and annual periods beginning after December 15, 2011. The Company adopted this amendment and the required disclosures are provided in Note 6 — “Fair Value of Assets and Liabilities.” Deferred Policy Acquisition Costs In October 2010, the FASB amended the general accounting principles for Financial Services – Insurance as it relates to accounting for costs associated with acquiring or renewing insurance contracts. This amendment clarifies that only those costs that result directly from and are essential to the contract transaction and that would not have been incurred had the contract transaction not occurred can be capitalized. It also defines acquisitions costs as costs that are related directly to the successful acquisitions of new or renewal insurance contracts. The amendment is effective for fiscal years and interim periods beginning after December 15, 2011. The retrospective adoption of this amendment on January 1, 2012, resulted in a reduction in the Company’s deferred acquisition cost asset and a corresponding reduction to equity, reflected in the financial statements in all periods. There will be a decrease in amortization subsequent to adoption due to the reduced deferred acquisition cost asset. There has also been a reduction in the level of future costs the Company defers; thereby increasing expenses incurred in future periods. The cumulative effect of the adoption of this amendment was a decrease to total stockholders’ equity of $318.4 million and a decrease in the deferred policy acquisition costs balance of $470.1 million on January 1, 2012. Comprehensive Income In February 2013, the FASB amended the general accounting principles for Comprehensive Income as it relates to the reporting of amounts reclassified out of accumulated other comprehensive income. The amendment requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. This amendment also requires entities to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. However, this is only necessary if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendment is effective for interim and annual reporting periods beginning after December 31, 2012. The Company adopted this amendment and the required disclosures are provided in Note 3 — “Accumulated Other Comprehensive Income.” In June 2011, the FASB amended the general accounting principles for Comprehensive Income as it relates to the presentation of comprehensive income. This amendment requires entities to present the total of comprehensive income, the components of net income, and the components of other comprehensive income in either a continuous statement of comprehensive income or in two separate but consecutive statements. The amendment does not change the items that must be reported in other comprehensive income. In December 2011, the FASB amended the general accounting principles for Comprehensive Income as it relates to the presentation of comprehensive income. This amendment defers the requirement to present the effects of reclassifications out of accumulated other comprehensive income on the Company’s consolidated statements of income, which was required in the Comprehensive Income amendment made in June 2011. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company adopted these amendments and the required presentation is provided in the Condensed Consolidated Statements of Comprehensive Income. Future Adoption of New Accounting Standards Income Taxes In July 2013, the FASB amended the general accounting principles for Income Taxes as it relates to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This amendment clarifies that an unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. However, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and not combined with deferred tax assets. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this amendment is not expected to have an impact on the Company's condensed consolidated financial statements.
