Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying condensed consolidated financial statements of Globe Life have been prepared in accordance with the instructions to Form 10-Q. Therefore, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America (GAAP) for annual financial statements. However, in the opinion of management, these statements include all adjustments, consisting of normal recurring adjustments, which are necessary for a fair presentation of the condensed consolidated financial position at June 30, 2023, and the condensed consolidated results of operations, comprehensive income, and cash flows for the periods ended June 30, 2023 and 2022. The interim period condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements that are included in the Form 10-K filed with the Securities Exchange Commission (SEC) on February 23, 2023.
Use of Estimates	Use of Estimates: The preparation of consolidated 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 liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See further documentation in the significant accounting policies or the accompanying notes.
Significant Accounting Policy Updates	Significant Accounting Policy Updates: The following accounting policies were updated since the 2022 Form 10-K due to the adoption of ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (ASU 2018-12). Refer to Note 2—New Acc ounting Stan dards for additional information on the financial statement impacts related to the adoption of this standard.
Future Policy Benefits	Future Policy Benefits—The liability for future policy benefits for traditional and limited-payment long duration life and health products comprises approximately 92% of the total liability for future policy benefits. The liability is determined each reporting period based on the net level premium method. This method requires the liability for future policy benefits be calculated as the present value of estimated future policyholder benefits and the related termination expenses, less the present value of estimated future net premiums to be collected from policyholders. Net level premiums reflect a recomputed net premium ratio1 using actual experience since the issue date or the Transition Date, and expected future experience. The liability is accrued as premium revenue is recognized and adjusted for differences between actual and expected experience. Long-duration insurance contracts issued by the Company are grouped into cohorts based on the contract issue year, distribution channel, legal entity, and product type. Both the present value of expected future benefit payments and the present value of expected future net premiums are based primarily on assumptions of discount rates, mortality, morbidity, lapse, and persistency. Each quarter, the Company remeasures its liability for future policy benefits using current discount rates with the effect of the change recognized in Other Comprehensive Income, a component of shareholders’ equity. In addition, the Company recognizes a liability remeasurement gain or loss within the Condensed Consolidated Statements of Operations using original discount rates, and relating to actual experience under the net premium calculation, as compared to the prior reporting period assumptions. The Company regularly reviews its cash flow assumptions (mortality, morbidity, lapses, and persistency) used to calculate the change in the liability for future policy benefits. These cash flow assumptions are updated as necessary in the third quarter of every year, or more frequently if suggested by experience. If cash flow assumptions are changed, the net premium ratio is recalculated from the original issue date, or the Transition Date, using actual experience and projected future cash flows. When the expected future net premiums exceed the expected future gross premiums, or the present value of future policyholder benefits exceeds the present value of expected future gross premiums, the liability for future policy benefits is adjusted with changes recognized in policyholder benefits on the Condensed Consolidated Statements of Operations. The cash flow assumptions do not include an adjustment for adverse deviation. Mortality tables used for individual life insurance include various industry tables and reflect modifications based on Company experience. Morbidity assumptions for individual health are based on Company experience and industry data. Lapse and persistency assumptions are based on Company experience. The liability for future policy benefits is discounted as noted above, using a current upper-medium grade fixed-income instrument yield that reflects the duration characteristics of the liability for future policy benefits. The methodology for determining current discount rates consists of constructing a discount rate curve intended to be reflective of the currency and tenor of the insurance liability cash flows. The methodology is designed to prioritize observable inputs based on market data available in the local debt markets denominated in the same currency as the policies. For the discount rates applicable to tenors for which the single-A debt market is not liquid or there is little or no observable market data, the Company will use estimation techniques consistent with the fair value guidance in ASC 820. We further accrete interest as a component of policyholder benefits using the original discount rate that is locked-in during the year of contract issuance. The original discount rates (or the locked-in discount rates) are used for interest accretion purposes and for the determination of net premiums, whereas the current discount rates are used for purposes of valuing the liability. The liability for future policy benefits for annuity and interest sensitive life-type products is represented by policy account value. For limited-payment contracts, a deferred profit liability is also recorded, with changes recognized in income over the life of the contract in proportion to the amount of insurance in force.
Deferred Acquisition Costs	Deferred Acquisition Costs—Certain costs of acquiring new insurance business are deferred and recorded as an asset. These costs are capitalized on a grouped contract basis and amortized over the expected term of the related contracts, and are essential for the acquisition of new insurance business. Deferred acquisition costs (DAC) are directly related to the successful issuance of an insurance contract, and primarily include sales commissions, policy issue costs, direct to consumer advertising costs, and underwriting costs. Additionally, DAC includes the value of business acquired (VOBA), which are the costs of acquiring blocks of insurance from other companies or through the acquisition of other companies. These costs represent the difference between the fair value of the contractual insurance assets acquired and liabilities assumed, compared against the assets and liabilities for insurance contracts that the Company issues or holds measured in accordance with GAAP. DAC is amortized on a constant-level basis over the expected term of the grouped contracts, with the related expense included in amortization of deferred acquisition costs on the Condensed Consolidated Statements of Operations. The in-force metric used to compute the DAC amortization rate is annualized premium in force. The assumptions used to amortize acquisition costs include mortality, morbidity, and persistency. These assumptions are reviewed at least annually and revised in conjunction with any change in the future policy benefit assumptions. The effect of changes in the assumptions are recognized over the remaining expected contract term as a revision of future amortization amounts. VOBA is amortized on a basis that is consistent with DAC, as described above, and is subject to periodic recoverability and loss recognition testing to determine if there is a premium deficiency. These tests evaluate whether the present value of future contract-related cash flows will support the capitalized VOBA asset. These cash flows consist primarily of premium income, less benefits and expenses. The present value of these cash flows, less the reserve liability, is then compared with the unamortized balance. In the event the estimated present value of net cash flows is less, the deficiency would be recognized by a charge to earnings and either a reduction of unamortized acquisition costs or an increase in the liability for future benefits.
Accounting Pronouncements Adopted and Accounting Pronouncements Yet to be Adopted	Accounting Pronouncements Adopted in the Current Year: On January 1, 2023, the Company adopted ASU 2018-12 (also referred to as Long Duration Targeted Improvements or LDTI) on a modified retrospective basis as of the transition date (Transition Date) of January 1, 2021. The amended guidance is a significant change to the accounting and disclosure of long-duration life and health insurance contracts. The modified retrospective transition method requires the updated standard be applied to all long-duration life and health contracts, which has resulted in the adjustment of the 2021 and 2022 consolidated financial statements. Accounting Pronouncements Yet to be Adopted: ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, adds disclosure requirements specific to equity securities subject to contractual sale restrictions. The disclosures clarify the nature of the contractual sale as well as the duration of the restriction and the circumstances that could cause a lapse in the restriction. This standard is effective for the Company on January 1, 2024, and will be implemented on a prospective basis. The Company does not expect the standard will have a material impact on the Consolidated Financial Statements.
