New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted in 2020 Effective January 1, 2020, the Company adopted ASC 326, Financial Instruments—Credit Losses. This new standard replaced the incurred loss model used to measure impairment losses for financial assets measured at amortized cost with a current expected credit loss (CECL) model and also made changes to the impairment model for available-for-sale investments. Under the CECL model, allowances are established for expected credit losses to be recognized over the life of financial assets. Application of the CECL model does not impact the Company's investment portfolio, which is not measured at amortized cost, but it impacts certain of the Company's other financial assets, including its reinsurance recoverables and receivables. ASC 326 also replaced the OTTI model with an impairment allowance model, subject to reversal, for available-for-sale investments, which are measured at fair value. As a result of adopting ASC 326, the Company increased its allowances for credit losses related to its reinsurance recoverables and receivables by $3.8 million and $1.0 million, respectively, which was recorded through a cumulative-effect adjustment to retained earnings as of January 1, 2020 ($3.8 million, net of taxes). The Company continues to apply the previous guidance to 2019 and prior periods. The following ASUs issued by the FASB are relevant to the Company's operations and were adopted effective January 1, 2020. These ASUs did not have a material impact on the Company's financial position, results of operations or cash flows: •ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement •ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract •ASU No. 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The ASU requires insurance entities with long duration contracts to: (1) review and, if there is a change, update the assumptions used to measure cash flows at least annually, as well as update the discount rate assumption at each reporting date; (2) measure all market risk benefits associated with deposit (or account balance) contracts at fair value; and (3) disclose liability rollforwards and information about significant inputs, judgments, assumptions and methods used in measurement, including changes thereto and the effect of those changes on measurement. In July 2020, the FASB proposed an update to ASU No. 2018-12 to defer its effective date. The proposed update would make the ASU effective for the Company during the first quarter of 2023. ASU No. 2018-12 will, among other things, impact the discount rate used in estimating reserves for the Company’s life and annuity reinsurance portfolio, which is in runoff. Currently, the discount rate assumption is locked-in for the life of the contracts, unless there is a loss recognition event. The Company is currently evaluating ASU No. 2018-12 to determine the impact that adopting this standard will have on its consolidated financial statements. The following ASUs issued by the FASB are relevant to the Company's operations and are not yet effective. These ASUs are not expected to have a material impact on the Company's financial position, results of operations or cash flows: •ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes •ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting
