Organization, Consolidation and Presentation of Financial Statements [Abstract]
CONSOLIDATION AND BASIS OF PRESENTATION	CONSOLIDATION AND BASIS OF PRESENTATION The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. In the opinion of management, the accompanying Condensed Consolidated Financial Statements contain all adjustments necessary to present fairly the financial position and results of operations of National Western Life Group, Inc. ("NWLGI") and its wholly owned subsidiaries (collectively, the “Company”), on a basis consistent with the prior audited consolidated financial statements, as of June 30, 2021, and for the three and six months ended June 30, 2021 and June 30, 2020. Such adjustments are of a normal recurring nature. Certain reclasses of prior year balances have been made for comparison. In addition, certain segment information disclosed in Note 6 has been revised. The results of operations for the six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year. It is recommended that these Condensed Consolidated Financial Statements be read in conjunction with the audited consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 which is accessible free of charge through the Company's internet site at www.nwlgi.com or the Securities and Exchange Commission internet site at www.sec.gov . The Condensed Consolidated Balance Sheet at December 31, 2020 has been derived from the audited consolidated financial statements as of that date. The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of NWLGI and its wholly owned subsidiaries: National Western Life Insurance Company ("NWLIC" or "National Western"), Regent Care San Marcos Holdings, LLC, NWL Services, Inc., and N.I.S. Financial Services, Inc. ("NIS"). National Western's wholly owned subsidiaries include The Westcap Corporation, NWL Financial, Inc., NWLSM, Inc., Braker P III, LLC, and Ozark National Life Insurance Company ("Ozark National"). All significant intercorporate transactions and accounts have been eliminated in consolidation. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Significant estimates in the accompanying Condensed Consolidated Financial Statements include: (1) liabilities for future policy benefits, (2) valuation of derivative instruments, (3) recoverability and amortization of deferred policy acquisition costs ("DPAC"), deferred sales inducements ("DSI"), the value of business acquired ("VOBA"), and the cost of reinsurance ("COR"), (4) valuation allowances for deferred tax assets, (5) goodwill, (6) allowances for credit losses on debt securities and mortgage loans, and (7) commitments and contingencies. As a result of executing a funds withheld coinsurance agreement at December 31, 2020, the Company implemented accounting policies related to trading debt securities and the embedded derivative on reinsurance in its financial statements. Trading securities represent debt securities that are included in the fund assets withheld as part of the funds withheld coinsurance agreements to support the policyholder liability obligations ceded to the reinsurer. Trading debt securities are reported in the accompanying Condensed Consolidated Financial Statements at their fair values with changes in their fair values reflected as a component of Net investment income in the Condensed Consolidated Statements of Earnings. Since these trading debt securities pertain to investment activities related to coinsurance agreements rather than as an income strategy based on active trading, they are classified as investing activities in the Condensed Consolidated Statements of Cash Flows. Under the terms of the coinsurance funds withheld agreement, while the assets are withheld, the associated interest and credit risk of these assets are transferred to the reinsurer creating an embedded derivative on reinsurance in the funds withheld liability. Accordingly, the Company is required to bifurcate the embedded derivative from the host contract in accordance with ASC 815-15. The bifurcated embedded derivative on reinsurance is computed as the fair value unrealized gain (loss) on the underlying funds withheld assets. This amount is included as a component of the funds withheld liability balance reported on the Condensed Consolidated Balance Sheets, with changes in the embedded derivative on reinsurance reported in Net investment income (loss) in the Condensed Consolidated Statements of Earnings. The embedded derivative on reinsurance is classified as a Level 2 financial instrument in the fair value hierarchy because its valuation input is the fair value market adjustments on the underlying Level 2 debt securities. See Note (10) Fair Values of Financial Instruments for further details of fair value disclosures. In the Condensed Consolidated Statements of Cash Flows, changes in the funds withheld liability are reported as operating activities. Realized gains on funds withheld assets are transferred to the reinsurer and reported as investing activities in the Condensed Consolidated Statements of Cash Flows. The table below shows the net unrealized gains and losses on available-for-sale securities that were reclassified out of accumulated other comprehensive income for the three and six months ended June 30, 2021 and June 30, 2020.

New Accounting Pronouncements

Accounting Policies [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS Recent accounting 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 . This update is aimed at improving the Codification as it relates to long-duration contracts which will improve the timeliness of recognizing changes in the liability for future policy benefits, simplify accounting for certain market-based options, simplify the amortization of deferred acquisition costs, and improve the effectiveness of required disclosures. Amendments include the following: A. Require insurance entity to (1) review and update assumptions used to measure cash flows at least annually (with changes recognized in net income) and (2) update discount rate assumption at each reporting date (with changes recognized in other comprehensive income). B. Require insurance entity to measure all market risk benefits associated with deposit (i.e. account balance) contracts at fair value, with change in fair value attributable to change in instrument-specific credit risk recognized in other comprehensive income. C. Simplify amortization of deferred acquisition costs and other balances amortized in proportion to premiums, gross profits, or gross margins and require those balances be amortized on constant level basis over expected term of related contract. Deferred acquisition costs are required to be written off for unexpected contract terminations but are not subject to impairment test. D. Require insurance entity to add disclosures of 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. Insurance entity must also disclose information about significant inputs, judgments, assumptions, and methods used in measurement, including changes in those inputs, judgments, and assumptions, and the effect of those changes on measurement. These updates are required to be applied retrospectively to the earliest period presented in the financial statements for fiscal periods beginning after December 15, 2022, with early adoption permitted. The Company has performed a preliminary gap analysis and created a roadmap for implementation of this standard by the effective date and is evaluating the impact of the new guidance on its Consolidated Financial Statements. Accounting pronouncements adopted In December 2019, the FASB issued ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740) , which simplifies various aspects of the income tax accounting guidance and will be applied using different approaches depending on the specific amendment. The amendments are effective for fiscal periods beginning after December 15, 2020. Early adoption is permitted. The adoption of this ASU did not have a material effect on the results of operations or financial position of the Company. In June 2016, the FASB released ASU 2016-13, Financial Instruments - Credit Losses , which revises the credit loss recognition criteria for certain financial assets measured at amortized cost. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model ("CECL"). The objective of the CECL model is for the reporting entity to recognize its estimate of current expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments in this Update add clarification and correction to ASU 2016-13 around expected recoveries for purchased financial assets with credit deterioration, transition relief for troubled debt restructurings, disclosures related to accrued interest receivables, and financial assets secured by collateral maintenance provisions. The guidance for these pronouncements was effective for interim and annual periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to beginning retained earnings. Effective January 1, 2020, the Company adopted the expected loss recognition model related to mortgage loans, debt securities held to maturity, and reinsurance recoverable using a modified retrospective approach. The change in accounting, net of tax, of $3.0 million was recorded as a charge to retained earnings in the first quarter of 2020 reflecting initial allowance for estimated credit losses balances of $1.2 million on mortgage loans and $3.3 million on debt securities held to maturity. The estimated credit losses for reinsurance recoverable were immaterial to the financial statements, but are monitored on a quarterly basis for any changes. Refer to Note (9) Investments for more information. Certain disclosures required by ASU 2016-13 are not included in the Consolidated Financial Statements as the impact of this standard was not material. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the AICPA, and the SEC did not, or are not believed by management to, have a material impact on the Company’s present or future Consolidated Financial Statements.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITY Robert L. Moody, Sr., through the Robert L. Moody Revocable Trust, controls 99.0% of the total outstanding shares of the Company's Class B common stock as of June 30, 2021. Holders of the Company's Class A common stock elect one-third of the Board of Directors of the Company, and holders of the Class B common stock elect the remainder. Any cash or in-kind dividends paid on each share of Class B common stock are to be only one-half of the cash or in-kind dividends paid on each share of Class A common stock. In the event of liquidation of the Company, the Class A stockholders will receive the par value of their shares; then the Class B stockholders shall receive the par value of their shares; and the remaining net assets of the Company shall be divided between the stockholders of both Class A and Class B stock based upon the number of shares held. As the sole owner of National Western, all dividends declared by National Western are payable entirely to NWLGI and are eliminated in consolidation. National Western is restricted by state insurance laws as to dividend amounts which may be paid to stockholders without prior approval from the Colorado Division of Insurance. The restrictions are based on the lesser of statutory earnings from operations, excluding capital gains, or 10% of statutory surplus of National Western as of the previous year-end. Under these guidelines the maximum dividend payment which may be made without prior approval in 2021 is $10.0 million. Ozark National is similarly restricted under the state insurance laws of Missouri as to dividend amounts which may be paid to stockholders without prior approval to the greater of 10.0% of the statutory surplus of the company from the preceding year-end or the company's net gain from operations, excluding capital gains, from the prior calendar year. Based upon this restriction, the maximum dividend payment which may be made in 2021 without prior approval is $20.0 million. All dividends declared by Ozark National are payable entirely to NWLIC as the sole owner and are eliminated in consolidation.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share of common stock are computed by dividing net earnings available to each class of common stockholders on an as if distributed basis by the weighted-average number of common shares outstanding for the period. Diluted earnings per share, by definition, reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock, that then shared in the distributed earnings of each class of common stock. U.S. GAAP requires a two-class presentation for the Company's two classes of common stock. The Company currently has no share-based compensation awards outstanding that could be redeemed for shares of common stock. Net earnings for the periods shown below are allocated between Class A shares and Class B shares based upon (1) the proportionate number of shares issued and outstanding as of the end of the period, and (2) the per share dividend rights of the two classes under the Company's Restated Certificate of Incorporation (the Class B dividend per share is equal to one-half the Class A dividend per share).

Retirement Benefits [Abstract]
PENSION AND OTHER POSTRETIREMENT PLANS	PENSION AND OTHER POSTRETIREMENT PLANS (A) Defined Benefit Pension Plans National Western sponsors a qualified defined benefit pension plan covering employees enrolled prior to 2008. The plan provides benefits based on the participants' years of service and compensation. The Company makes annual contributions to the plan that comply with the minimum funding provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). On October 19, 2007, National Western's Board of Directors approved an amendment to freeze the pension plan as of December 31, 2007. The freeze ceased future benefit accruals to all participants and closed the plan to any new participants. In addition, all participants became immediately 100% vested in their accrued benefits as of that date. As participants are no longer earning a credit for service, future qualified defined benefit plan expense is projected to be minimal. Fair values of plan assets and liabilities are measured as of the prior December 31 for each year. The following table summarizes the components of net periodic benefit cost. Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 (In thousands) Service cost $ 30 27 60 54 Interest cost 131 169 263 337 Expected return on plan assets (356) (316) (712) (631) Amortization of net loss 135 145 269 290 Net periodic benefit cost $ (60) 25 (120) 50 The service cost shown above for each period represents plan expenses expected to be paid out of plan assets. Under the clarified rules of the Pension Protection Act, plan expenses paid from plan assets are to be included in the plan's service cost component. The Company's minimum required contribution for the 2021 plan year is $0.0 million. There was $0.7 million in planned contributions remaining for the 2020 plan year as of June 30, 2021. As of June 30, 2021, the Company has made $0.2 million in contributions to the plan for the 2020 plan year and $0.0 million in contributions to the plan for the 2021 plan year. The components of net periodic benefit cost including service cost are reported in the line item “Other operating expenses” in the Condensed Consolidated Statements of Earnings. National Western also sponsors three non-qualified defined benefit pension plans. The first plan covers certain senior officers and provides benefits based on the participants' years of service and compensation. The primary pension obligations and administrative responsibilities of the plan are maintained by a pension administration firm, which is a subsidiary of American National Group, Inc. ("American National"), a related party. American National has guaranteed the payment of pension obligations under the plan. However, the Company has a contingent liability with respect to the plan should these entities be unable to meet their obligations under the existing agreements. Also, the Company has a contingent liability with respect to the plan in the event that a plan participant continues employment with National Western beyond age seventy, the aggregate average annual participant salary increases exceed 10% per year, or any additional employees become eligible to participate in the plan. If any of these conditions are met, the Company would be responsible for any additional pension obligations resulting from these items. Amendments were made to the plan to allow an additional employee to participate and to change the benefit formula for the then Chairman of the Company. As previously mentioned, these additional obligations are a liability to the Company. Effective December 31, 2004, this plan was frozen with respect to the continued accrual of benefits of the then Chairman and the then President of the Company in order to comply with law changes under the American Jobs Creation Act of 2004 ("Act"). Effective July 1, 2005, National Western established a second non-qualified defined benefit plan for the benefit of the then Chairman of the Company. This plan is intended to provide for post-2004 benefit accruals that mirror and supplement the pre-2005 benefit accruals under the previously discussed non-qualified plan, while complying with the requirements of the Act. Effective November 1, 2005, National Western established a third non-qualified defined benefit plan for the benefit of the then President of the Company. This plan is intended to provide for post-2004 benefit accruals that supplement the pre-2005 benefit accruals under the first non-qualified plan as previously discussed, while complying with the requirements of the Act. The following table summarizes the components of net periodic benefit costs for the non-qualified defined benefit plans. Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 (In thousands) Service cost $ 309 303 618 605 Interest cost 260 337 521 675 Amortization of prior service cost 15 15 30 30 Amortization of net loss 1,283 1,445 2,565 2,890 Net periodic benefit cost $ 1,867 2,100 3,734 4,200 As the plans are not funded, there is no expected return on plan assets shown in the net periodic benefit cost table above. The Company expects to contribute $2.0 million to these plans in 2021. As of June 30, 2021, the Company has contributed $0.9 million to the plans. The components of net periodic benefit cost including service cost are reported in the line item “Other operating expenses” in the Condensed Consolidated Statements of Earnings. Ozark National and NIS have no defined benefit plans. (B) Postretirement Employment Plans Other Than Pension National Western sponsors two healthcare plans that were amended in 2004 to provide postretirement benefits to certain fully-vested individuals. The plans are unfunded. The following table summarizes the components of net periodic benefit costs. Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 (In thousands) Interest cost $ 37 42 74 83 Amortization of net loss 73 39 146 79 Net periodic benefit cost $ 110 81 220 162 As the plans are not funded, there is no expected return on plan assets shown in the net periodic benefit cost table above. The Company expects to contribute minimal amounts to the plans in 2021. Ozark National and NIS do not offer postemployment benefits.

Segment Reporting [Abstract]
SEGMENT AND OTHER OPERATING INFORMATION	SEGMENT AND OTHER OPERATING INFORMATION The Company defines its reportable operating segments as domestic life insurance, international life insurance, annuities, and ONL and Affiliates (previously referred to as "Acquired Businesses"). These segments are organized based on product types, geographic marketing areas, and business groupings. Ozark National and NIS have been combined into a separate segment given its inter-related marketing and sales approach which consists of a coordinated sale of a non-participating whole life insurance product (Ozark National) and a mutual fund investment product (NIS). A fifth category "All Others" primarily includes investments and earnings of non-operating subsidiaries as well as other remaining investments and assets not otherwise supporting specific segment operations. A summary of segment information as of June 30, 2021 and December 31, 2020 for the Condensed Consolidated Balance Sheet items and for the three and six months ended June 30, 2021 and June 30, 2020 for the Condensed Consolidated Statements of Earnings is provided below.

Share-Based Payments

Share-Based Payments	6 Months Ended
	Jun. 30, 2021
Share-based Payment Arrangement [Abstract]
SHARE-BASED PAYMENTS	SHARE-BASED PAYMENTS Effective June 20, 2008, the Company's shareholders approved a 2008 Incentive Plan (“2008 Plan”) which provided for the grant of any or all of the following types of awards to eligible employees: (1) stock options, including incentive stock options and nonqualified stock options; (2) stock appreciation rights ("SARs"), in tandem with stock options or freestanding; (3) restricted stock or restricted stock units; and, (4) performance awards. The number of shares of Class A, $1.00 par value, common stock which were allowed to be issued under the 2008 Plan, or as to which SARs or other awards were allowed to be granted, could not exceed 300,000. This plan was assumed by NWLGI from National Western pursuant to the terms of the holding company reorganization in 2015. On June 15, 2016, stockholders of NWLGI approved an amended and restated 2008 Plan ("Incentive Plan"), which extended the term of the 2008 Plan for ten years from the date of stockholder approval. The Incentive Plan includes additional provisions, most notably regarding the definition of performance objectives which could be used in the issuance of the fourth type of award noted above (performance awards). All of the employees of the Company and its subsidiaries are eligible to participate in the current Incentive Plan. In addition, directors of the Company are eligible to receive the same types of awards as employees except that they are not eligible to receive incentive stock options. Company directors, including members of the Compensation and Stock Option Committee, are eligible for nondiscretionary stock options. At the end of 2018, all stock options granted under the 2008 Plan had been exercised, forfeited, or expired. SARs granted prior to 2016 vest 20% annually following three years of service following the grant date. Employee SARs granted 2016 and thereafter vest 33.3% annually following one year of service from the date of the grant. Directors' SARs grants vest 20% annually following one year of service from the date of grant. Effective during August 2008, the Company adopted and implemented a limited stock buy-back program with respect to the 2008 Plan which provided stock option holders the additional alternative of selling shares acquired through the exercise of options directly back to the Company. Option holders could elect to sell such acquired shares back to the Company at any time within ninety (90) days after the exercise of options at the prevailing market price as of the date of notice of election. The buy-back program did not alter the terms and conditions of the 2008 Plan. This plan was assumed as well by NWLGI from National Western pursuant to the terms of the holding company reorganization. There are currently no stock options issued and outstanding. The Incentive Plan allows for certain other share or unit awards which are solely paid out in cash based on the value of the Company's shares, or changes therein, as well as the financial performance of the Company under pre-determined target performance metrics. Certain awards, such as restricted stock units ("RSUs") provide solely for cash settlement based upon the market price of the Company's Class A common shares, often referred to as "phantom stock-based awards" in equity compensation plans. Unlike share-settled awards, which have a fixed grant-date fair value, the fair value of unsettled or unvested liability awards is remeasured at the end of each reporting period based on the change in fair value of a share. The liability and corresponding expense are adjusted accordingly until the award is settled. For employees, the vesting period for RSUs is 100% at the end of 3 years from the grant date. RSUs granted prior to 2019 are payable in cash at the vesting date equal to the closing price of the Company's Class A common share on the three years anniversary date. RSUs granted in 2019 and forward are payable in cash at the 3 years vesting date equal to the 20-day moving average closing price of the Company’s Class A common share at that time. Other awards may involve performance share units ("PSUs") which are units granted at a specified dollar amount per unit, typically linked to the Company's Class A common share price, that are subsequently multiplied by an attained performance factor to derive the number of PSUs to be paid as cash compensation at the vesting date. PSUs also vest three years from the date of grant. For PSUs, the performance period begins the first day of the calendar year for which the PSUs are granted and runs three PSU awards covering the three year measurement period ended December 31, 2019 were paid out in the first quarter of 2020. The performance factor during the measurement period used to determine compensation payouts was 101.19% of the pre-defined metric target. PSU awards covering the three year measurement period ended December 31, 2020 were paid out in April 2021. The performance factor during the measurement period used to determine compensation payouts was 85.16% of the pre-defined metric target. Directors of the Company are eligible to receive RSUs under the Incentive Plan. Unlike RSUs granted to officers, the RSUs granted to directors vest one year from the date of grant. RSUs granted prior to 2019 are payable in cash at the vesting date equal to the closing price of the Company's Class A common share at that time. RSUs granted in 2019 and forward are payable in cash at the vesting date equal to the 20-day moving average closing price of the Company’s Class A common share at that time. No awards were granted to officers and directors during the six months ended June 30, 2021 and 2020. The Company uses the current fair value method to measure compensation costs for awards granted under the share-based plans. As of June 30, 2021 and December 31, 2020, the liability balance was $8.1 million and $6.2 million, respectively. A summary of awards by type and related activity is detailed below.

The total intrinsic value of share-based compensation exercised and paid was $2.0 million and $1.9 million for the six months ended June 30, 2021 and 2020, respectively. The total fair value of SARs, RSUs, and PSUs vested during the six months ended June 30, 2021 and 2020 was $0.0 million and $1.8 million, respectively. No cash amounts were received from the exercise of stock options under the Plans during the periods reported. The following table summarizes information about SARs outstanding at June 30, 2021. There were no options outstanding as of June 30, 2021.

The SARs shown above with exercise price of $132.56 have a remaining contractual life of less than one year. The holders for this grant have until the end of the contractual life of December 14, 2021 to exercise these holdings or otherwise forfeit the SAR grants held. In estimating the fair value of the SARs outstanding at June 30, 2021 and December 31, 2020, the Company employed the Black-Scholes option pricing model with assumptions detailed below. June 30, December 31, Expected term 0.5 to 9.4 years 1.0 to 9.9 years Expected volatility weighted-average 34.08 % 33.47 % Expected dividend yield 0.16 % 0.17 % Risk-free rate weighted-average 0.50 % 0.19 % The Company reviewed the contractual term relative to the SARs as well as perceived future behavior patterns of exercise. Volatility is based on the Company’s historical volatility over the expected term of the SARs by expected exercise date. The pre-tax compensation cost/(benefit) recognized in the financial statements related to these plans was $(0.5) million and $3.9 million for the three and six months ended June 30, 2021 and $2.4 million and $(3.8) million for the three and six months ended June 30, 2020, respectively. The related tax expense/(benefit) recognized was $0.1 million and $(0.8) million for the three and six months ended June 30, 2021 and $(0.5) million and $0.8 million for the three and six months ended June 30, 2020, respectively. As of June 30, 2021, the total pre-tax compensation expense related to non-vested share-based awards not yet recognized was $7.4 million. This amount is expected to be recognized over a weighted-average period of 1.3 years. The Company recognizes compensation cost over the graded vesting periods.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES (A) Legal Proceedings In the normal course of business, the Company is involved or may become involved in various legal actions in which claims for alleged economic and punitive damages have been or may be asserted, some for substantial amounts. In recent years, carriers offering life insurance and annuity products have faced litigation, including class action lawsuits, alleging improper product design, improper sales practices, and similar claims. As previously disclosed, the Company has been a defendant in prior years in such class action lawsuits. Given the uncertainty involved in these types of actions, the ability to make a reliable evaluation of the likelihood of an unfavorable outcome or an estimate of the amount of or range of potential loss is endemic to the particular circumstances and evolving developments of each individual matter on its own merits. On September 28, 2017, a purported shareholder derivative lawsuit was filed in the 122nd District Court of Galveston County, State of Texas entitled Robert L. Moody, Jr. derivatively on behalf of National Western Life Insurance Company and National Western Life Group, Inc. v. Ross Rankin Moody, et al., naming certain current and former directors and current officers as defendants. The complaint challenged the directors’ oversight of insurance sales to non-U.S. residents and alleged that the defendants breached their fiduciary duties in the conduct of their duties as board members by failing to act (i) on an informed basis and (ii) in good faith or with the honest belief that their actions were in the best interests of the Company. The complaint sought an undetermined amount of damages, attorneys’ fees and costs, and equitable relief, including the removal of the Company’s Chairman and Chief Executive Officer and other board members and/or officers of the Company. The Company believes that the claims in the complaint were baseless and without merit, will continue to vigorously defend this lawsuit, and was awarded reimbursement of legal costs and expenses from plaintiff as detailed below. The Company believes, based on information currently available, that the final outcome of this lawsuit will not have a material adverse effect on the Company’s business, results of operations, or consolidated financial position. The companies and directors filed their respective Pleas to the Jurisdiction ("Pleas") contesting the plaintiff's standing to even pursue this action, along with their Answers, on October 27, 2017. On December 14, 2017, plaintiff filed a Response to the Pleas and on December 21, 2017, the Court heard oral argument on the Pleas. Plaintiff then filed a First Amended Petition on January 11, 2018. The companies and directors filed a Supplement to the Pleas on January 30, 2018, to which plaintiff responded on February 1, 2018, and the companies and directors replied on February 9, 2018. On May 3, 2018, the Court issued a memorandum to all attorneys of record stating that the Court would grant the defendants' Pleas and asked the attorney for defendants to prepare and submit proposed orders/judgments granting the requested relief for consideration by the Court. The defendants filed such proposed order granting the Pleas on May 7, 2018. On May 16, 2018 the Court issued an Order granting the Pleas and dismissing Robert L. Moody, Jr.’s claims with prejudice, and plaintiff then filed a Motion to Transfer Venue (“MTTV”). Defendants filed an Application for Fees, seeking to recover defendants’ legal costs and expenses from plaintiff, and a Response to the MTTV on June 8, 2018. In response plaintiff filed a Motion to Vacate, a Response to the Application for Fees, and his own Request for Attorney’s Fees on July 5, 2018. Defendants filed a Response to the Motion to Vacate and to plaintiff’s Request for Attorney’s Fees on July 11, 2018, and the Court heard oral arguments on July 16, 2018. Plaintiff filed supplemental briefing in support of his July 5, 2018 filings on July 25, 2018, and defendants filed their response to plaintiff's supplemental briefing on July 27, 2018. On August 8, 2018 the Court issued an Order denying plaintiff's Motion to Vacate. Pursuant to the Court’s instructions, on October 5, 2018, defendants filed an Order Granting Application for Expenses. Defendants then filed a Motion for Entry of Final Judgment and a Request for Submission Date on Motion for Entry of Final Judgment on October 11, 2018, which the Court set as October 30, 2018. Plaintiff filed his Objection to Proposed Final Judgment and Objection to Proposed Order on Attorneys’ Fees on October 25, 2018, to which defendants filed a response on October 30, 2018. On November 11, 2018, the Court issued its Final Judgment: ordering Plaintiff to pay the companies $1,314,054 for reasonable and necessary fees and expenses, denying Plaintiff’s Motion to Transfer Venue, and dismissing Plaintiff’s counterclaim. Plaintiff appealed the Court’s Final Judgment to the First District Court of Appeals in Houston, TX. The court of appeals issued a panel decision on December 10, 2020 affirming the dismissal and award of attorneys’ fees and expenses to the companies. On January 22, 2021, Plaintiff filed a motion for rehearing of the affirmance of the award of attorneys’ fees and expenses. On July 27, 2021, the Court of Appeals vacated its December 10, 2020 judgment and withdrew its earlier opinion, and issued a new judgment and opinion again affirming the dismissal and award of attorneys’ fees and expenses to the companies. In April of 2019, National Western defended a two-week jury trial in which it was alleged that it committed actionable Financial Elder Abuse in its issuance of a $100,000 equity indexed annuity to the Plaintiff in the case of Williams v Pantaleoni et al , Case No. 17CV03462, Butte County California Superior Court. The Court entered an Amended Judgment on the Jury Verdict on July 27, 2019 against National Western in the amount of $14,949 for economic damages and $2.9 million in non-economic and punitive damages. National Western vigorously disputes the verdicts and the amounts awarded, and in furtherance of such, filed a Motion for Judgment Notwithstanding Jury Verdict and a Motion for New Trial, both of which were rejected by the Court. On September 9, 2019, NWLIC filed its Notice of Appeal. On November 11, 2019, the judge awarded the Plaintiff attorney’s fees in the amount of $1.26 million. Both the Plaintiff and NWLIC appealed this ruling. On June 11, 2021, the appellate court reversed the judgment and directed the trial court to enter judgment in favor of NWLIC. Plaintiff has filed an appeal with the Supreme Court of California. In the Form 10-Q for the period ended September 30, 2020, the Company reported that it experienced a data event in which an intruder accessed and exfiltrated certain data from the Company's network. As a result of this event, the Company reported in its Form 10-K for the year ended December 31, 2020, that it was aware of two proposed class actions filed against National Western, Mildred Baldwin, on behalf of herself and others similarly situated vs. National Western Life Insurance Company , Missouri Circuit Court for the 18th Judicial Circuit (Pettis County) filed February 16, 2021, and Douglas Dyrssen Sr., individually and on behalf of all others similarly situated vs. National Western Life Insurance Company and National Western Life Group, Inc. , United States District Court for the Eastern District of California filed March 8, 2021. The parties agreed to consolidate those two proposed class actions into a single proposed class action, Mildred Baldwin, on behalf of herself and others similarly situated vs. National Western Life Insurance Company , United States District Court for the Western District of Missouri. Baldwin is seeking an undetermined amount of damages, attorneys' fees and costs, injunctive relief, declaratory and other equitable relief, and enjoinment. National Western filed a Motion to Dismiss on July 16, 2021. On July 26, 2021, the parties filed a Joint Motion to Stay Pending Mediation, which the court denied. At this time, no prediction can be made as to the likelihood or amount of any recovery against National Western. It is possible other actions may be filed against the Company due to the data event. Although there can be no assurances, at the present time, the Company does not anticipate that the ultimate liability arising from such other potential, pending, or threatened legal actions will have a material adverse effect on the financial condition or operating results of the Company. Separately, Brazilian authorities commenced an investigation into possible violations of Brazilian criminal law in connection with the issuance of National Western insurance policies to Brazilian residents, and in assistance of such investigation a Commissioner appointed by the U.S. District Court for the Western District of Texas issued a subpoena in March of 2015 upon NWLIC to provide information relating to such possible violations. No conclusion can be drawn at this time as to its outcome or how such outcome may impact the Company’s business, results of operations or financial condition. National Western has been cooperating with the relevant governmental authorities in regard to this matter. (B) Financial Instruments In order to meet the financing needs of its customers in the normal course of business, the Company is a party to financial instruments with off-balance sheet risk. These financial instruments are commitments to extend credit which involve elements of credit and interest rate risk in excess of the amounts recognized in the Condensed Consolidated Balance Sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amounts, assuming that the amounts are fully advanced and that collateral or other security is of no value. Commitments to extend credit are legally binding agreements to lend to a customer that generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments do not necessarily represent future liquidity requirements, as some could expire without being drawn upon. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company controls the credit risk of these transactions through credit approvals, limits, and monitoring procedures. The Company had $26.0 million commitments to fund new loans and no commitments to extend credit relating to existing loans at June 30, 2021. The Company evaluates each customer's creditworthiness on a case-by-case basis. The Company had commitments to make capital contributions to alternative investment funds of $210.2 million as of June 30, 2021.

INVESTMENTS	INVESTMENTS (A) Investment Gains and Losses The Company uses the specific identification method in computing realized gains and losses. The table below presents realized gains and losses for the periods indicated. Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (In thousands) Available-for-sale debt securities: Realized gains on disposal $ 4,823 1,730 6,239 2,491 Realized losses on disposal — — — — Held-to-maturity debt securities: Realized gains on disposal — 1,395 — 4,119 Realized losses on disposal — — — — Real estate gains (losses) (1,407) — (1,407) — Other (1) — (1) — Totals $ 3,415 3,125 4,831 6,610 Disposals in the held-to-maturity category during the three and six months ended June 30, 2020 represent calls initiated by the credit issuer of the debt security. At year-end 2020, the Company transferred all of its held-to-maturity debt securities to the available-for-sale category as the result of entering into a funds withheld reinsurance agreement effective December 31, 2020. The Company's policy was to initiate disposals of debt securities in the held-to-maturity category only in instances in which the credit status of the issuer came into question and the realization of all or a significant portion of the investment principal of the holding was deemed to be in jeopardy. For the three months ended June 30, 2021 and 2020 the percentage of total gains on bonds due to the call of securities was 100.0% and 99.9%, respectively. For the six months ended June 30, 2021 and 2020 the percentage of gains on bonds due to the call of securities was 100.0% and 99.8%, respectively. (B) Debt Securities The Company transferred all of its debt securities to the available-for-sale classification as of December 31, 2020. The table below presents amortized costs and fair values of debt securities available-for-sale at June 30, 2021.

Debt securities balances at June 30, 2021 and December 31, 2020 include Ozark National holdings of $810.3 million and $811.6 million in available-for-sale. As part of the acquisition effective January 31, 2019 the Company employed purchase accounting procedures in accordance with GAAP which revalued the acquired investment portfolio to their fair values as of the date of the acquisition. These fair values became the book values for Ozark National from that point going forward. Accordingly, unrealized gains and losses for the Ozark National debt securities represent the changes subsequent to the purchase accounting book values established at the acquisition. The following table shows the gross unrealized losses and fair values of the Company's available-for-sale debt securities by investment category and length of time the individual securities have been in a continuous unrealized loss position at June 30, 2021. Debt Securities Available-for-Sale Less than 12 Months 12 Months or Greater Total Fair Unrealized Fair Unrealized Fair Unrealized (In thousands) States and political subdivisions $ 14,124 (276) 1,788 (102) 15,912 (378) Foreign governments 7,436 (435) — — 7,436 (435) Public utilities 635 (9) — — 635 (9) Corporate 331,777 (7,264) 21,845 (585) 353,622 (7,849) Asset-backed 23,382 (132) — — 23,382 (132) Totals $ 377,354 (8,116) 23,633 (687) 400,987 (8,803) The following table shows the gross unrealized losses and fair values of the Company's available-for-sale debt securities by investment category and length of time that the individual securities have been in a continuous unrealized loss position at December 31, 2020.

The gross unrealized losses for debt securities are made up of 47 individual issues, or 3.7 % of the total debt securities held available-for-sale by the Company at June 30, 2021. The market value of these bonds as a percent of amortized cost approximates 97.9%. Of the 47 securities, 6, or 12.8%, fall in the 12 months or greater aging category and 43 were rated investment grade at June 30, 2021. The amortized cost and fair value of investments in debt securities available-for-sale at June 30, 2021, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The Company employed a cohort cumulative loss rate method in estimating current expected credit losses with respect to its held-to-maturity debt securities. This method applies publicly available industry wide statistics of default incidence by defined segmentations of debt security investments combined with future assumptions regarding economic conditions (i.e. GDP forecasts) both in the near term and the long term. The Company utilized Moody's loss rates by industry type and credit ratings and applied them to each major bond category. These bond categories were further segmented by credit ratings and by maturities of two years and less and more than two years. The following table presents the allowance for debt securities credit losses for the three and six months ended June 30, 2021 and 2020. Three Months Ended June 30, 2021 2020 2021 2020 Debt Securities Debt Securities (In thousands) Balance, beginning of period $ — 6,039 — — Provision January 1, 2020 for adoption of new accounting guidance — — — — (Releases)/provision during period — (1,099) — — Balance, end of period $ — 4,940 — — Six Months Ended June 30, 2021 2020 2021 2020 Debt Securities Debt Securities (In thousands) Balance, beginning of period — — — — Provision January 1, 2020 for adoption of new accounting guidance — 3,334 — — (Releases)/provision during period — 1,606 — — Balance, end of period — 4,940 — — As previously noted, the Company reclassified all held-to-maturity debt securities to available-for-sale as of December 31, 2020. Provisions to and releases from the allowance for credit losses in 2020 are recorded in net investment income in the Condensed Consolidated Statements of Earnings. The Company determines current expected credit losses for available-for-sale debt securities in accordance with FASB ASC Subtopic 326-30 when fair value is less than amortized cost, interest payments are missed, and the security is experiencing credit issues. Based on its review, the Company determined none of these investments required an allowance for credit loss at June 30, 2021 or 2020. The Company's operating procedures include monitoring the investment portfolio on an ongoing basis for any changes in issuer facts and circumstances that might lead to future need for a credit loss allowance. (C) Transfer of Securities The Company reassessed its classification of its held-to-maturity portfolio at December 31, 2020 as a result of a funds withheld coinsurance agreement entered into with a third party reinsurer. A portion of the transferred debt securities was added to a funds withheld account for which the reinsurer provides investment management services and does not intend to hold the securities until maturity. Consequently, the Company determined that its continued classification of held-to-maturity debt securities was not appropriate and transferred the entire balance at that time to available-for-sale. (D) Mortgage Loans and Real Estate A financing receivable is a contractual right to receive money on demand or on fixed or determinable dates that is recognized as an asset in a company's statement of financial position. The Company's mortgage, participation and mezzanine loans on real estate are the only financing receivables included in the Condensed Consolidated Balance Sheets. Credit and default risk are minimized through strict underwriting guidelines and diversification of underlying property types and geographic locations. In addition to being secured by the property, mortgage loans with leases on the underlying property are often guaranteed by the lease payments. This approach has proved to result in quality mortgage loans with few defaults. Mortgage loan interest income is recognized on an accrual basis with any premium or discount amortized over the life of the loan. Prepayment and late fees are recorded on the date of collection. The Company targets a minimum specified yield on mortgage loan investments determined by reference to currently available debt security instrument yields plus a desired amount of incremental basis points. During the past several years, the low interest rate environment and a competitive marketplace resulted in fewer loan opportunities being available that met the Company's required rate of return. During the first half of 2020, mortgage loan originations were further impeded by the COVID-19 pandemic and its effects upon the commercial real estate market. Mortgage loans originated by the Company totaled $70.3 million for the six months ended June 30, 2021 and $80.2 million for the year ended December 31, 2020. Loans in foreclosure, loans considered impaired or loans past due 90 days or more are placed on a non-accrual status. If a mortgage loan is determined to be on non-accrual status, the mortgage loan does not accrue any revenue into the Condensed Consolidated Statements of Earnings. The loan is independently monitored and evaluated as to potential impairment or foreclosure. If delinquent payments are made and the loan is brought current, then the Company returns the loan to active status and accrues income accordingly. The Company had no mortgage loans past due 90 days or more at June 30, 2021 or 2020 and as a result all interest income was recognized at June 30, 2021 and 2020. As a result of the economic climate change induced by the COVID-19 virus, various mortgage loan borrowers of the Company requested a temporary forbearance of principal payments on loans in the range of three to nine months. During 2020 there were eight loans representing an aggregate principal balance of $29.2 million with borrowers meeting specified criteria of the Company that forbearance terms were agreed to by the Company. As of June 30, 2021 all forbearance loans have returned to the terms of the original loan agreements. The following table represents the mortgage loan portfolio by loan-to-value ratio. June 30, 2021 December 31, 2020 Amount % Amount % (In thousands) (In thousands) Mortgage Loans by Loan-to-Value Ratio (1): Less than 50% $ 100,376 25.3 $ 66,635 19.9 50% to 60% 111,867 28.2 64,536 19.3 60% to 70% 140,928 35.4 153,414 45.8 70% to 80% 44,143 11.1 50,422 15.0 Gross balance 397,314 100.0 335,007 100.0 Market value adjustment 36 — — — Allowance for credit losses (3,238) (0.8) (2,486) (0.7) Totals $ 394,112 99.2 $ 332,521 99.3 (1) Loan-to-Value Ratio is determined using the most recent appraised value. Appraisals are required at the time of funding and may be updated if a material change occurs from the original loan agreement. Market value adjustments are recorded for mortgage loan investments for which the Company has elected to measure the loan at fair value. During the quarter ended June 30, 2021, the investment manager associated with the funds withheld coinsurance arrangement executed a mortgage loan investment for the funds withheld assets under the reinsurance treaty. The Company elected fair value measurement for this mortgage loan, which will be included in the funds withheld assets, for financial reporting purposes. All mortgage loans are analyzed quarterly in order to monitor the financial quality of these assets. Based on ongoing monitoring, mortgage loans with a likelihood of becoming delinquent are identified and placed on an internal “watch list.” Among the criteria that may indicate a potential problem include: major tenant vacancies or bankruptcies, late payments, and loan relief/restructuring requests. The mortgage loan portfolio is analyzed for the need for a valuation allowance on any loan that is on the internal watch list, in the process of foreclosure or that currently has a valuation allowance. Effective January 1, 2020, the Company implemented FASB ASU 2016-13, Financial Instruments-Credit Losses , which revised the credit loss recognition criteria for certain financial assets measured at amortized cost. The guidance replaced the existing incurred loss recognition model with an expected loss recognition model (“CECL”). The objective of the CECL model is for the reporting entity to recognize its estimate of current expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. For mortgage loan investments the Company is using the Weighted Average Remaining Maturity ("WARM") method, which uses an average annual charge-off rate applied to each mortgage loan risk category. At January 1, 2020, a CECL balance of $1.2 million was recorded for mortgage loans which incorporated the previous year-end balance under the prior accounting method. The adjustment resulted in a charge to retained earnings as a change in accounting, net of tax, of $0.4 million. Subsequent changes in the allowance for current expected credit losses for mortgage loans are reported in net investment income in the Condensed Consolidated Statements of Earnings. The following table represents the mortgage loan allowance for credit losses.

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS For financial instruments, the FASB provides guidance which defines fair value, establishes a framework for measuring fair value under GAAP, and requires additional disclosures about fair value measurements. In compliance with this GAAP guidance, the Company has categorized its financial instruments, based on the priority of the inputs to the valuation technique, into a three level hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the Condensed Consolidated Balance Sheets are categorized as follows: Level 1: Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. These generally provide the most reliable evidence and are used to measure fair value whenever available. The Company's Level 1 assets are equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets. Level 2: Fair value is based upon significant inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable for substantially the full term of the asset or liability through corroboration with observable market data as of the reporting date. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, model-derived valuations whose inputs are observable or whose significant value drivers are observable and other observable inputs. The Company’s Level 2 assets include fixed maturity debt securities (corporate and private bonds, government or agency securities, asset-backed and mortgage-backed securities). The Company's Level 2 liabilities include the embedded derivative on reinsurance. Valuations are generally obtained from third party pricing services for identical or comparable assets or determined through use of valuation methodologies using observable market inputs. Level 3: Fair value is based on significant unobservable inputs which reflect the entity’s or third party pricing service’s assumptions about the assumptions market participants would use in pricing an asset or liability. The Company’s Level 3 assets are over-the-counter derivative contracts and mortgage loans. The Company’s Level 3 liabilities consist of share-based compensation obligations and certain equity-index product-related embedded derivatives. Valuations are estimated based on non-binding broker prices or internally developed valuation models or methodologies, discounted cash flow models and other similar techniques. The following tables set forth the Company’s assets and liabilities that are measured at fair value on a recurring basis as of the date indicated: June 30, 2021 Total Level 1 Level 2 Level 3 (In thousands) Debt securities, available-for-sale $ 9,617,027 — 9,617,027 — Debt securities, trading 1,066,454 — 1,066,454 — Equity securities 21,132 21,132 — — Mortgage loans 2,729 — — 2,729 Derivatives, index options 114,840 — — 114,840 Total assets $ 10,822,182 21,132 10,683,481 117,569 Policyholder account balances (a) $ 155,265 — — 155,265 Other liabilities (b) (64,196) — (72,340) 8,144 Total liabilities $ 91,069 — (72,340) 163,409 During the three and six months ended June 30, 2021, the Company made no transfers from Level 2 to Level 3 for debt securities available-for-sale.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES Fixed-index products provide traditional fixed annuities and universal life contracts with the option to have credited interest rates linked in part to an underlying equity index or a combination of equity indices. The equity return component of such policy contracts is identified separately and accounted for in future policy benefits as embedded derivatives on the Condensed Consolidated Balance Sheets. The remaining portions of these policy contracts are considered the host contracts and are recorded separately as fixed annuity or universal life contracts. The host contracts are accounted for under debt instrument type accounting in which future policy benefits are recorded as discounted debt instruments and accreted, using the effective yield method, to their minimum account values at their projected maturities or termination dates. The Company purchases over-the-counter index options, which are derivative financial instruments, to hedge the equity return component of its fixed-index annuity and life products. The index options act as hedges to match closely the returns on the underlying index or indices. The amounts which may be credited to policyholders are linked, in part, to the returns of the underlying index or indices. As a result, changes to policyholders' liabilities are substantially offset by changes in the value of the options. Cash is exchanged upon purchase of the index options and no principal or interest payments are made by either party during the option periods. Upon maturity or expiration of the options, cash may be paid to the Company depending on the performance of the underlying index or indices and terms of the contract. The Company does not elect hedge accounting relative to these derivative instruments. The index options are reported at fair value in the accompanying Condensed Consolidated Financial Statements. The changes in the values of the index options and the changes in the policyholder liabilities are both reflected in the Condensed Consolidated Statements of Earnings. Any changes relative to the embedded derivatives associated with policy contracts are reflected in contract interest in the Condensed Consolidated Statements of Earnings. Any gains or losses from the sale or expiration of the options, as well as period-to-period changes in values, are reflected as net investment income in the Condensed Consolidated Statements of Earnings. Although there is credit risk in the event of nonperformance by counterparties to the index options, the Company does not expect any of its counterparties to fail to meet their obligations, given their high credit ratings. In addition, credit support agreements are in place with all counterparties for option holdings in excess of specific limits, which may further reduce the Company's credit exposure. Effective December 31, 2020, the Company entered into a coinsurance funds withheld reinsurance agreement under which identified assets are maintained in a funds withheld account but the associated interest and credit risk of these assets has been transferred to the reinsurer, representing a total return swap with a floating rate leg. Accordingly, the Company bifurcates the embedded derivative for reinsurance from the host contract in accordance with GAAP. The fair value of the embedded derivative funds withheld liability is computed as the unrealized gain (loss) on the underlying funds withheld assets and is included in the funds withheld liability on the Condensed Consolidated Balance Sheets, with the change reported in net investment income in the Condensed Consolidated Statements of Earnings. Changes in the funds withheld liability are reported in operating activities in the Condensed Consolidated Statements of Cash Flows.

The anticipated asset management fees to be collected increases or decreases based upon the most recent performance of index options and adds to or reduces the offset applied to the embedded derivative liability (increasing or decreasing contract interest expense). For the three months ended June 30, 2021 and 2020, the change in the embedded derivative liability due to the expected collectability of asset management fees increased/(decreased) contract interest expense by $2.1 million and $(3.7) million, respectively. For the six months ended June 30, 2021 and 2020, contract interest expense was increased/(decreased) by $6.5 million and $25.6 million, respectively, for the expected collectability of asset management fees.

The value of insurance licenses was estimated using the market approach to value, based on values paid for licenses in recent shell company transactions. The value of internally developed software was estimated using the replacement cost method. Trademarks, trade names and internally developed software are amortized using a straight-line method over the estimated useful lives. These intangible assets will be evaluated for impairment if indicators of impairment arise. Insurance licenses were determined to have an indefinite useful life. The Company evaluates the useful life of insurance licenses at each reporting period to determine whether the useful life remains indefinite.

Accounting Policies [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS Recent accounting 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 . This update is aimed at improving the Codification as it relates to long-duration contracts which will improve the timeliness of recognizing changes in the liability for future policy benefits, simplify accounting for certain market-based options, simplify the amortization of deferred acquisition costs, and improve the effectiveness of required disclosures. Amendments include the following: A. Require insurance entity to (1) review and update assumptions used to measure cash flows at least annually (with changes recognized in net income) and (2) update discount rate assumption at each reporting date (with changes recognized in other comprehensive income). B. Require insurance entity to measure all market risk benefits associated with deposit (i.e. account balance) contracts at fair value, with change in fair value attributable to change in instrument-specific credit risk recognized in other comprehensive income. C. Simplify amortization of deferred acquisition costs and other balances amortized in proportion to premiums, gross profits, or gross margins and require those balances be amortized on constant level basis over expected term of related contract. Deferred acquisition costs are required to be written off for unexpected contract terminations but are not subject to impairment test. D. Require insurance entity to add disclosures of 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. Insurance entity must also disclose information about significant inputs, judgments, assumptions, and methods used in measurement, including changes in those inputs, judgments, and assumptions, and the effect of those changes on measurement. These updates are required to be applied retrospectively to the earliest period presented in the financial statements for fiscal periods beginning after December 15, 2022, with early adoption permitted. The Company has performed a preliminary gap analysis and created a roadmap for implementation of this standard by the effective date and is evaluating the impact of the new guidance on its Consolidated Financial Statements. Accounting pronouncements adopted In December 2019, the FASB issued ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740) , which simplifies various aspects of the income tax accounting guidance and will be applied using different approaches depending on the specific amendment. The amendments are effective for fiscal periods beginning after December 15, 2020. Early adoption is permitted. The adoption of this ASU did not have a material effect on the results of operations or financial position of the Company. In June 2016, the FASB released ASU 2016-13, Financial Instruments - Credit Losses , which revises the credit loss recognition criteria for certain financial assets measured at amortized cost. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model ("CECL"). The objective of the CECL model is for the reporting entity to recognize its estimate of current expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments in this Update add clarification and correction to ASU 2016-13 around expected recoveries for purchased financial assets with credit deterioration, transition relief for troubled debt restructurings, disclosures related to accrued interest receivables, and financial assets secured by collateral maintenance provisions. The guidance for these pronouncements was effective for interim and annual periods beginning after December 15, 2019, and for most affected instruments must be adopted using a modified retrospective approach, with a cumulative effect adjustment recorded to beginning retained earnings. Effective January 1, 2020, the Company adopted the expected loss recognition model related to mortgage loans, debt securities held to maturity, and reinsurance recoverable using a modified retrospective approach. The change in accounting, net of tax, of $3.0 million was recorded as a charge to retained earnings in the first quarter of 2020 reflecting initial allowance for estimated credit losses balances of $1.2 million on mortgage loans and $3.3 million on debt securities held to maturity. The estimated credit losses for reinsurance recoverable were immaterial to the financial statements, but are monitored on a quarterly basis for any changes. Refer to Note (9) Investments for more information. Certain disclosures required by ASU 2016-13 are not included in the Consolidated Financial Statements as the impact of this standard was not material. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the AICPA, and the SEC did not, or are not believed by management to, have a material impact on the Company’s present or future Consolidated Financial Statements.
Fair Value Measurements	FAIR VALUES OF FINANCIAL INSTRUMENTS For financial instruments, the FASB provides guidance which defines fair value, establishes a framework for measuring fair value under GAAP, and requires additional disclosures about fair value measurements. In compliance with this GAAP guidance, the Company has categorized its financial instruments, based on the priority of the inputs to the valuation technique, into a three level hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the Condensed Consolidated Balance Sheets are categorized as follows: Level 1: Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. These generally provide the most reliable evidence and are used to measure fair value whenever available. The Company's Level 1 assets are equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets. Level 2: Fair value is based upon significant inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable for substantially the full term of the asset or liability through corroboration with observable market data as of the reporting date. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, model-derived valuations whose inputs are observable or whose significant value drivers are observable and other observable inputs. The Company’s Level 2 assets include fixed maturity debt securities (corporate and private bonds, government or agency securities, asset-backed and mortgage-backed securities). The Company's Level 2 liabilities include the embedded derivative on reinsurance. Valuations are generally obtained from third party pricing services for identical or comparable assets or determined through use of valuation methodologies using observable market inputs. Level 3: Fair value is based on significant unobservable inputs which reflect the entity’s or third party pricing service’s assumptions about the assumptions market participants would use in pricing an asset or liability. The Company’s Level 3 assets are over-the-counter derivative contracts and mortgage loans. The Company’s Level 3 liabilities consist of share-based compensation obligations and certain equity-index product-related embedded derivatives. Valuations are estimated based on non-binding broker prices or internally developed valuation models or methodologies, discounted cash flow models and other similar techniques.
