Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statements	Basis of Financial Statements The financial information in this report presented for interim periods is unaudited and includes the accounts of Fidelity National Financial, Inc. and its subsidiaries (collectively, “we,” “us,” “our,” the "Company" or “FNF”) prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All adjustments made were of a normal, recurring nature. This report should be read in conjunction with our Annual Report on Form 10-K (our "Annual Report") for the year ended December 31, 2021. Description of the Business We are a leading provider of (i) title insurance, escrow and other title-related services, including loan sub-servicing, valuations, default services and home warranty products, (ii) technology to the real estate and mortgage industries and (iii) annuity and life insurance products. FNF is one of the nation’s largest title insurance companies operating through its title insurance underwriters - Fidelity National Title Insurance Company ("FNTIC"), Chicago Title Insurance Company ("Chicago Title"), Commonwealth Land Title Insurance Company ("Commonwealth Title"), Alamo Title Insurance and National Title Insurance of New York Inc. - which collectively issue more title insurance policies than any other title company in the United States. Through our subsidiary, ServiceLink Holdings, LLC ("ServiceLink"), we provide mortgage transaction services, including title-related services and facilitation of production and management of mortgage loans. We are also a leading provider of insurance solutions serving retail annuity and life customers and institutional clients through our wholly-owned subsidiary, F&G Annuities & Life ("F&G"). For information about our reportable segments refer to Note H Segment Information. Recent Developments F&G Distribution On March 14, 2022, our Board of Directors approved a dividend to our shareholders, on a pro rata basis, of 15% of the common stock of F&G (the "F&G Distribution"). We intend to retain control of F&G through our 85% ownership stake. The proposed F&G Distribution is subject to various conditions including the final approval of our Board of Directors, the effectiveness of appropriate filings with the U.S Securities and Exchange Commission (the "SEC"), and any applicable regulatory approvals. The record date and distribution settlement date will be determined by our Board of Directors prior to the distribution. Upon completion of the F&G Distribution, our shareholders as of the record date are expected to own stock in both publicly traded companies. The proposed F&G Distribution is intended to be structured as a taxable dividend to our shareholders and is targeted to be completed in late third quarter or early fourth quarter of 2022. However, there can be no assurance regarding the timeframe for completing the F&G Distribution or that the conditions of the F&G Distribution will be met. Income Tax Income tax expense was $155 million and $166 million in the three months ended March 31, 2022 and 2021, respectively. Income tax expense as a percentage of earnings before income taxes was 28% and 22% in the three months ended March 31, 2022 and 2021, respectively. The increase in income tax expense as a percentage of earnings before taxes in the three months ended March 31, 2022 as compared to the corresponding period in 2021 is primarily attributable to the recording of a valuation allowance in the 2022 period for tax benefits associated with deferred tax assets, related to realized losses on the past sales of discontinued operations, for which it is more likely than not that we will not be able to realize for tax purposes. Earnings Per Share Basic earnings per share, as presented on the Condensed Consolidated Statement of Earnings, is computed by dividing net earnings available to common shareholders in a given period by the weighted average number of common shares outstanding during such period. In periods when earnings are positive, diluted earnings per share is calculated by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding plus assumed conversions of potentially dilutive securities. For periods when we recognize a net loss, diluted loss per share is equal to basic loss per share as the impact of assumed conversions of potentially dilutive securities is considered to be antidilutive. We have granted certain stock options, shares of restricted stock and certain other convertible share based payments, which have been treated as common share equivalents for purposes of calculating diluted earnings per share for periods in which positive earnings have been reported. Options or other instruments, which provide the ability to purchase shares of our common stock that are antidilutive, are excluded from the computation of diluted earnings per share. There were fewer than 1 million antidilutive instruments outstanding during the three months ended March 31, 2022 and 2021. Recent Accounting Pronouncements Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU 2018-12, Financial Services-Insurance (Topic 944), Targeted Improvements to the Accounting for Long-Duration Contracts, effective for fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. This update introduced the following requirements: assumptions used to measure cash flows for traditional and limited-payment contracts must be reviewed at least annually with the effect of changes in those assumptions being recognized in the statement of operations; the discount rate applied to measure the liability for future policy benefits and limited-payment contracts must be updated at each reporting date with the effect of changes in the rate being recognized in other comprehensive income; market risk benefits associated with deposit contracts must be measured at fair value, with the effect of the change in the fair value attributable to a change in the instrument-specific credit risk being recognized in other comprehensive income; deferred acquisition costs are no longer required to be amortized in proportion to premiums, gross profits, or gross margins; instead, those balances must be amortized on a constant level basis over the expected term of the related contracts; deferred acquisition costs must be written off for unexpected contract terminations; and disaggregated rollforwards of beginning to ending balances of the liability for future policy benefits, policyholder account balances, market risk benefits, separate account liabilities and deferred acquisition costs, as well as information about significant inputs, judgments, assumptions, and methods used in measurement are required to be disclosed. The amendments in this ASU may be early adopted as of the beginning of an annual reporting period for which financial statements have not yet been issued, including interim financial statements. We will not early adopt this standard. We have identified specific areas that will be impacted by the new guidance. This guidance will bring significant changes to how we account for certain insurance and annuity products within our business. As we continue to make progress on adopting this new guidance, we will be able to provide a better assessment of the specific impacts to our consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this update eliminate the Troubled Debt Restructuring ("TDR") recognition and measurement guidance for creditors and, instead, require that an entity evaluate whether the modification represents a new loan or a continuation of an existing loan. The amendments also enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, these amendments require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within the scope of Subtopic 326-20. The guidance is effective for entities that have adopted ASU 2016-13 Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326) for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, though early adoption is permitted. We do not currently expect to early adopt this standard and are in the process of assessing this standard and its impact on our accounting and disclosures.
