Basis Of Presentation [Abstract]
Basis Of Presentation	2. BASIS OF PRESENTATION The unaudited interim consolidated financial statements of the Company for the three and six months ended June 30, 2020 and 2019 include all adjustments, consisting of normal recurring accruals, which, in the opinion of management, are necessary for a fair statement of the results on an interim basis. Certain financial information, which is normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), has been omitted since it is not required for interim reporting purposes. The December 31, 2019 consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results for the three and six months ended June 30, 2020 and 2019 are not necessarily indicative of the results for a full year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the years ended December 31, 2019, 2018 and 2017 included in the Company’s most recent Form 10-K filing. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities (and disclosure of contingent assets and liabilities) at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Ultimate actual results could differ, possibly materially, from those estimates. This is particularly true given the fluid and continuing nature of the COVID-19 pandemic. This is an ongoing event and so is the Company’s evaluation and analysis. While the Company’s analysis considers all aspects of its operations, it does not take into account legal, regulatory or legislative intervention that could retroactively mandate or expand coverage provisions. Given the uncertainties in the current public health and economic environment, there could be an adverse impact on results for the Property & Casualty industry and the Company for the remainder of the year. The impact is dependent on the shape and length of the economic recovery. With recent changes in executive management and organizational structure, the Company manages its reinsurance and insurance operations as autonomous units and key strategic decisions are based on the aggregate operating results and projections for these segments of business. Accordingly, effective January 1, 2020, the Company revised it reporting segments to Reinsurance Operations and Insurance Operations. This replaces the previous reported segments of U.S. Reinsurance, International (reinsurance) and Insurance. The prior year presented segment information has been reformatted to reflect this change. All intercompany accounts and transactions have been eliminated. Certain reclassifications and format changes have been made to prior years’ amounts to conform to the 2020 presentation. Application of Recently Issued Accounting Standard Changes. Accounting for Income Taxes. In December 2019, The Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, which provides simplification of existing guidance for income taxes, including the removal of certain exceptions related to recognition of deferred tax liabilities on foreign subsidiaries. The guidance is effective for annual reporting periods beginning after December 15, 2020 and interim periods within that annual reporting period. The Company is currently evaluating the impact of the adoption of ASU 2019-12 on its financial statements. Simplification of Disclosure Requirements. In August 2018, the Securities and Exchange Commission (“SEC”) issued Final Rule Release #33-10532 (“the Rule”) which addresses the simplification of the SEC’s disclosure requirements for quarterly and annual financial reports. The main change addressed by the Rule that is applicable to the Company is a new requirement to disclose changes in equity by line item with subtotals for each interim reporting period on the Statements of Changes in Shareholders’ Equity. The Rule became effective for all financial reports filed after November 5, 2018 (30 days after its publication in the Federal Register), except for the additional requirement for the Statements of Changes in Shareholders’ Equity which was to be implemented for first quarter 2019 reporting. The Company has adopted the portions of the Rule that became effective November 5, 2018. The portion of the Rule related to the new requirement for the Statements of Changes in Shareholders’ Equity was adopted by the Company in the first quarter of 2019. Accounting for Cloud Computing Arrangement. In August 2018, FASB issued ASU 2018-15, which outlines accounting for implementation costs of a cloud computing arrangement that is a service contract. This guidance requires that implementation costs of a cloud computing arrangement that is a service contract must be capitalized and expensed in accordance with the existing provisions provided in Subtopic 350-40 regarding development of internal use software. In addition, any capitalized implementation costs should be amortized over the term of the hosting arrangement. The guidance is effective for annual reporting periods beginning after December 15, 2019 and interim periods within that annual reporting period. The Company adopted the guidance as of January 1, 2020. The adoption of ASU 2018-15 did not have a material impact on the Company’s financial statements. Accounting for Impact on Income Taxes due to Tax Reform. In December 2017, the SEC issued Staff Accounting Bulletin (“SAB”) 118, which provides guidance on the application of FASB Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, due to the enactment of TCJA. SAB 118 became effective upon release. The Company has adopted the provisions of SAB 118 with respect to measuring the tax effects for the modifications to the determination of tax basis loss reserves. In 2018, the Company recorded adjustments to the amount of tax expense it recorded in 2017 with respect to the TCJA as estimated amounts were finalized, which did not have a material impact on the Company’s financial statements. Amortization of Bond Premium. In March 2017, FASB issued ASU 2017-08 which outlines guidance on the amortization period for premium on callable debt securities. The new guidance requires that the premium on callable debt securities be amortized through the earliest call date rather than through the maturity date of the callable security. The guidance is effective for annual and interim reporting periods beginning after December 15, 2018. The Company adopted the guidance effective January 1, 2019. The adoption of ASU 2017-08 did not have a material impact on the Company’s financial statements. Valuation of Financial Instruments. In June 2016, FASB issued ASU 2016-13 (and has subsequently issued related guidance and amendments in ASU 2019-11 and ASU 2019-10 in November 2019) which outline guidance on the valuation of and accounting for assets measured at amortized cost and available for sale debt securities. The carrying value of assets measured at amortized cost will now be presented as the amount expected to be collected on the financial asset (amortized cost less an allowance for credit losses valuation account). Available for sale debt securities will now record credit losses through an allowance for credit losses, which will be limited to the amount by which fair value is below amortized cost. The guidance is effective for annual and interim reporting periods beginning after December 15, 2019. The Company adopted the guidance effective January 1, 2020. The adoption resulted in a cumulative adjustment of $907 thousand in retained earnings, which is disclosed separately within the Consolidated Statements of Shareholders’ Equity. Leases. In February 2016, FASB issued ASU 2016-02 (and subsequently issued ASU 2018-11 in July, 2018) which outline new guidance on the accounting for leases. The new guidance requires the recognition of lease assets and lease liabilities on the balance sheets for most leases that were previously deemed operating leases and required only lease expense presentation in the statements of operations. The guidance is effective for annual and interim reporting periods beginning after December 15, 2018. The Company adopted ASU 2016-02 effective January 1, 2019 and elected to utilize a cumulative-effect adjustment to the opening balance of retained earnings for the year of adoption. Accordingly, the Company’s reporting for the comparative periods prior to adoption continue to be presented in the financial statements in accordance with previous lease accounting guidance. The Company also elected to apply the package of practical expedients applicable to the Company in the updated guidance for transition for leases in effect at adoption. The Company did not elect the hindsight practical expedient to determine the lease term of existing leases (e.g. The Company did not re-assess lease renewals, termination options nor purchase options in determining lease terms). The adoption of the updated guidance resulted in the Company recognizing a right-of-use asset of $60,325 thousand as part of other assets and a lease liability of $66,551 thousand as part of other liabilities in the consolidated balance sheet, as well as de-recognizing the liability for deferred rent that was required under the previous guidance. The cumulative effect adjustment to the opening balance of retained earnings was zero. The adoption of the updated guidance did not have a material effect on the Company’s results of operations or liquidity. Any issued guidance and pronouncements, other than those directly referenced above, are deemed by the Company to be either not applicable or immaterial to its financial statements.
