Accounting Changes and Error Corrections [Abstract] |
New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | Adoption of Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses, and subsequent additional implementation guidance (collectively referred to as “ASU 2016-13”) that changes the way entities recognize impairment of financial assets. The new guidance requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets through the establishment of an ACL. The ACL is a measurement of expected losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Additionally, ASU 2016-03 requires the presentation of the impacted financial assets on the Consolidated Balance Sheet net of the ACL. We adopted this guidance on January 1, 2020, applied a modified retrospective approach for the adoption, and recorded a net cumulative-effect adjustment to increase the opening balance of 2020 retained earnings by $1.4 million, after tax. As prescribed in ASU 2016-13, we did not adjust the amortized cost basis of any securities for which we previously had recorded other-than-temporary impairment ("OTTI") losses. The cumulative-effect increase to retained earnings represents the net adjustment required to (i) establish the ACL on our held-to-maturity ("HTM") debt securities and (ii) re-estimate the ACL on our premiums receivables and reinsurance recoverables under ASU 2016-13. See Note 2. "Summary of Significant Accounting Policies" of this Form 10-K for accounting policy updates related to ASU 2016-13. Additionally, see Note 5. "Investments," Note 8. "Allowance for Credit Losses on Premiums Receivable," and Note 9. "Reinsurance" of this Form 10-K for additional information regarding expected credit losses related to the respective financial assets. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing certain disclosures, and modifying and adding disclosure requirements. The additional disclosure requirements include (i) the change in unrealized gains and losses for the period included in other comprehensive income (“OCI”) for recurring Level 3 fair value measurements held at the end of the reporting period, and (ii) the range and weighted average of significant observable inputs used to develop Level 3 fair value measurements. We adopted the provisions related to removed disclosures in the fourth quarter of 2019 and adopted the remaining disclosure requirements in the first quarter of 2020. As it requires disclosure only, ASU 2018-13 has no impact on our financial condition or results of operations. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing hosting service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted this guidance prospectively on January 1, 2020, and it did not have a material impact on our financial condition or results of operations. Pronouncements to be effective in the future In December 2019, the FASB issued ASU 2019-12, Income Taxes - Simplifying the Accounting for Income Taxes (“ASU 2019-12”). Among other items, ASU 2019-12 simplifies the accounting treatment of tax law changes and year-to-date losses in interim periods. An entity generally recognizes the effects of a change in tax law in the period of enactment; however, there is an exception for tax laws with delayed effective dates. Under current guidance, an entity may not adjust its annual effective tax rate for a tax law change until the period in which the law is effective. ASU 2019-12 provides that all effects of a tax law change, including adjustment of the estimated annual effective tax rate, are recognized in the period of enactment. For year-to-date losses in interim periods, an entity is required currently to estimate its annual effective tax rate for the full fiscal year at the end of each interim period and use that rate to calculate its income taxes on a year-to-date basis. When an interim period loss exceeds the anticipated loss for the year, the income tax benefit is limited to the amount that would be recognized if the year-to-date loss were the anticipated loss for the full year. ASU 2019-12 removes this limitation and allows an entity to compute its income tax benefit at each interim period based on its estimated annual effective tax rate. We will adopt this guidance on January 1, 2021 and it will not have a material impact to our financial condition, cash flows, or results of operations upon adoption. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions to the guidance in GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition away from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. Companies can elect to adopt ASU 2020-04 as of the beginning of the interim period that includes March 2020, or any date thereafter through December 31, 2022. We are currently evaluating the impact of this guidance on our financial condition and results of operations.
