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 annual financial statements. In the opinion of management, the accompanying Condensed Consolidated Financial Statements contain all adjustments necessary to present fairly the financial position of National Western Life Group, Inc. ("NWLGI") and its wholly owned subsidiaries (“Company”) as of June 30, 2019 , and the results of its operations and its cash flows for the three and six months ended June 30, 2019 and June 30, 2018 . Such adjustments are of a normal recurring nature. The results of operations for the six months ended June 30, 2019 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, 2018 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, 2018 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"). The results of operations for Ozark National and NIS include the five months ended June 30, 2019, subsequent to their acquisition effective January 31, 2019. 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, (4) valuation allowances for deferred tax assets, (5) other-than-temporary impairment losses on debt securities, (6) commitments and contingencies, and (7) valuation allowances for mortgage loans and real estate. During the first six months of 2019, the Company incorporated accounting estimates for business combinations, value of business acquired, and fair value measurement as a result of its acquisition of Ozark National and NIS. The table below shows the 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, 2019 and June 30, 2018 .

Accounting Policies [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS Recent accounting pronouncements not yet adopted On April 25, 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 various aspects of the following guidance previously issued related to financial instruments, based on feedback from stakeholders. A. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Areas for improvement . The amendments clarify guidance and implementation around accrued interest, transfers between classifications or categories for loans and debt securities, consideration of recoveries in estimating allowances, reinsurance recoveries, consideration of prepayments and estimated costs to sell when foreclosure is probable. Additionally, the amendments correct certain cross-references. B. ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Liabilities. The amendments clarify the scope of the original Update, and add clarification on the guidance and implementation around fair value disclosure requirements for nonpublic entities, measurement alternatives for equity securities without readily determinable fair values at nonrecurring fair value measurement, remeasurement of equity securities without readily determinable fair values at historical exchange rates, and associated disclosure requirements. C. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments clarify the guidance and implementation around partial-term fair value hedges of interest rate risk, amortization of fair value hedge basis adjustments, disclosure of fair value hedge basis adjustments, consideration of the hedged contractually specified interest rate under the hypothetical derivative method, scope for nonpublic entities, and application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments. The amendments contained in this update will be effective for the same fiscal years in which the original ASU becomes effective, or, if already implemented, annual periods beginning after the issuance of this update. The Company will be primarily affected by the clarifications provided to ASU 2016-13, which is still pending adoption. 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 periods beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. In August 2018, the FASB issued a new Concepts Statement No. 8 Conceptual Framework for Financial Reporting - Chapter 8, Notes to Financial Statements . This was issued as part of a disclosure framework project aimed at improving disclosures in financial statements. This issuance provides conceptual guidance that may be followed when determining items to include as disclosures in the notes to financial statements. In conjunction with this issuance, the FASB also issued two accounting standard updates (“ASU”) which identified a particular FASB Topic and evaluated its disclosures through the new conceptual framework of Concepts Statement No. 8, Chapter 8. This process resulted in the issuance of the following two ASUs. In August 2018, FASB issued ASU 2018-13 F air Value Measurement (Topic 820) Disclosure Framework - Changes to the Disclosure requirements for Fair Value Measurement. This update removed disclosures for 1) amount of and reasons for transfers between Level 1 and Level 2 for fair value hierarchy, 2) policy for timing of transfers between levels, 3) valuation process for Level 3 fair value measurements. This update also added disclosure requirement as follows: 1) changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at end of reporting period; 2) range and weighted average (or other reasonable quantitative measurement) of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments will be effective for interim periods beginning after December 15, 2019. Adoption of the guidance is not expected to have a material effect on the Company’s results of operations or financial position. In August 2018, FASB issued ASU 2018-14 Compensation-Retirement Benefits - Defined Benefit Plans-General (Subtopic 715-20) Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans . This update removed disclosures for 1) amounts in AOCI expected to be recognized as components of net periodic benefit cost over the next fiscal year, 2) amount and timing of plan assets expected to be returned to the employer, 3) related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, 4) the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of the net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. This update also added disclosures as follow: 1) weighted-average interest crediting rates for cash balance plans and other plans with promised crediting rates, 2) explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Finally, this update clarified that the following information for defined benefit pension plans should be disclosed: 1) projected benefit obligation (PBO) and fair value of plan assets for plans with PBO in excess of plan assets, 2) accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments will be effective for fiscal periods ending after December 31, 2020. Adoption of the guidance is not expected to have a material effect on the Company’s results of operations or financial position. 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. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of 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. The guidance is 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 income. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. Recent accounting pronouncements adopted In August 2018, the SEC released a final rule updating disclosure requirements, Disclosure Update and Simplification, which resulted in the additional interim disclosure of an analysis of changes in stockholders’ equity to be required for the current and comparative quarter and year-to-date interim periods. Registrants are required to provide an analysis of changes in each caption of stockholders’ equity and noncontrolling interests, which will be accompanied by dividends per share and in the aggregate for each class of shares. The disclosure must be presented in the form of a reconciliation, either as a separate statement or in the footnotes. The adoption of this ASU in 2019 did not have a material effect on the results of operations or financial position of the Company as this information in year-to-date format is already provided. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities , which amends the amortization period for certain purchased callable debt securities held at a premium. The amortization period for premiums is being shortened to the earliest call date. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The adoption of this ASU in 2019 did not have a material effect on the results of operations or financial position of the Company. In February 2016, the FASB issued new guidance on leasing transactions (ASU 2016-02, Leases - Topic 842). The new guidance is effective for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and requires a modified retrospective transition approach (subject to optional practical expedients). The new guidance requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months. Leases would be classified as finance or operating leases and both types of leases will be recognized on the balance sheet. Lessor accounting will remain largely unchanged from current guidance except for certain targeted changes. The new guidance will also require new qualitative and quantitative disclosures. Early adoption is permitted. The Company elected to early adopt this guidance in 2018. There was no material impact to the Company’s financial position, results of operations or cash flows as the result of the adoption of this ASU in 2018. 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.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	STOCKHOLDERS' EQUITY NWLIC 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, from the prior calendar year or 10% of statutory surplus of the company as of the previous calendar year-end. Under these guidelines the maximum dividend payment which may be made without prior approval in 2019 is $30.7 million . As the sole owner of NWLIC, all dividends declared by National Western are payable entirely to NWLGI and are eliminated in consolidation. 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% of the statutory surplus of the company from the prior 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 2019 without prior approval is $20.4 million . As part of the Stock Purchase Agreement dated October 3, 2018, by and between NWLIC and Ozark National's previous owner, the Missouri Department of Insurance granted approval for an extraordinary dividend of $102.7 million to be paid to the prior owner concurrent with the closing of the transaction effective January 31, 2019. Consequently, any additional dividends during 2019 will require prior approval of the Missouri Department of Insurance. As the sole owner of Ozark National, all dividends declared by Ozark National going forward are payable entirely to NWLIC and are eliminated in consolidation. In the first quarter of 2019, National Western declared and paid a $32.0 million dividend to NWLGI, the proceeds of which were used as part of the cash purchase of NIS. In the first quarter of 2018, National Western declared and paid a $3.0 million dividend to NWLGI. National Western did not declare or pay cash dividends during the three month periods ended June 30, 2019 and 2018. Ozark National did not declare or pay cash dividends on its shares during the five-month period ended June 30, 2019. NWLGI did no t declare or pay cash dividends on its common shares during the six months ended June 30, 2019 and 2018

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share of common stock are computed by dividing net income 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 income for the periods shown below is 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).

Pension and Other Postretirement Plans	6 Months Ended

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, 2019 2018 2019 2018 (In thousands) Service cost $ 24 28 48 56 Interest cost 210 225 420 450 Expected return on plan assets (272 ) (325 ) (544 ) (650 ) Amortization of prior service cost — — — — Amortization of net loss 165 131 330 262 Net periodic benefit cost $ 127 59 254 118 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 2019 plan year is $0.4 million . There was $0.5 million in planned contributions remaining for the 2018 plan year as of June 30, 2019 . As of June 30, 2019 , the Company had made $0.0 million in contributions to the plan for the 2019 plan year. The components of net periodic benefit cost including service cost are reported in the line item “Other operating expenses” in the income statement. 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 Insurance Company ("ANICO"), a related party. ANICO 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, 2019 2018 2019 2018 (In thousands) Service cost $ 126 90 251 180 Interest cost 256 213 512 426 Amortization of prior service cost 15 15 30 30 Amortization of net loss 348 176 696 352 Net periodic benefit cost $ 745 494 1,489 988 The Company expects to contribute $2.0 million to these plans in 2019 . As of June 30, 2019 , 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 income statement. 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, 2019 2018 2019 2018 (In thousands) Interest cost $ 50 40 99 80 Amortization of prior service cost 13 26 26 52 Amortization of net loss 61 38 122 75 Net periodic benefit cost $ 124 104 247 207 The Company expects to contribute minimal amounts to the plans in 2019 .

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 acquired companies. These segments are organized based on product types, geographic marketing areas, and business groupings. Ozark National and NIS have been combined into the segment "Acquired Businesses" 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). As disclosed in the Company's filings for 2018, National Western discontinued accepting applications for the Company's international products from residents of other countries in May 2018. 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, 2019 and December 31, 2018 for the Condensed Consolidated Balance Sheet items and for the three and six months ended June 30, 2019 and June 30, 2018 for the Condensed Consolidated Statement of Earnings is provided below.

Share-Based Payments

Share-Based Payments	6 Months Ended
	Jun. 30, 2019
Share-based Payment Arrangement [Abstract]
Share-Based Payments	SHARE-BASED PAYMENTS The Company had a stock and incentive plan ("1995 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 1995 Plan began on April 21, 1995, and was amended on June 25, 2004 to extend the termination date to April 20, 2010. The number of shares of Class A, $1.00 par value, common stock which were allowed to be issued under the 1995 Plan, or as to which SARs or other awards were allowed to be granted, could not exceed 300,000 . Effective June 20, 2008, the Company's shareholders approved a 2008 Incentive Plan (“2008 Plan”). The 2008 Plan is substantially similar to the 1995 Plan and authorized an additional number of Class A common stock shares eligible for issue not to exceed 300,000 . These plans were 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 1995 Plan and 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 forward vest 33.3% annually following one year of service from the date of the grant. Directors' stock option and SARs grants vest 20% annually following one year of service from the date of grant. Effective during March 2006, the Company adopted and implemented a limited stock buy-back program with respect to the 1995 Plan which provides stock option holders the additional alternative of selling shares acquired through the exercise of options directly back to the Company. Option holders may 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 1995 Plan; however, the program necessitated a change in accounting from the equity classification to the liability classification. In August 2008, the Company implemented another limited stock buy-back program, substantially similar to the 2006 program, for shares issued under the 2008 Plan. These plans were assumed as well by NWLGI from National Western pursuant to the terms of the holding company reorganization. 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". 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 three years from the grant date. The RSUs are payable in cash at the vesting date equal to the closing price of the Company's Class A common shares 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 in which the PSUs are granted and runs three calendar years. At that time, the three-year performance outcome will be measured against the pre-defined target amounts to determine the number of PSUs earned as compensation which are paid at the closing price of the Company's Class A common shares on the vesting date. PSU awards covering the three year measurement period ended December 31, 2018 were paid out in the first quarter of 2019. The performance factor during the measurement period used to determine compensation payouts was 93.86% 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. They are payable in cash at the vesting date equal to the closing price of the Company's Class A common shares at that time. No awards were granted to officers and directors during the six months ended June 30, 2019 and 2018 . The Company uses the current fair value method to measure compensation costs for awards granted under the share-based plans. As of June 30, 2019 and December 31, 2018 , the liability balance was $8.0 million and $11.9 million , respectively. A summary of awards by type and related activity is detailed below.

The total intrinsic value of share-based compensation exercised was $2.5 million and $1.9 million for the six months ended June 30, 2019 and 2018 , respectively. The total share-based compensation paid was $2.5 million and $1.9 million for the six months ended June 30, 2019 and 2018 , respectively. The total fair value of stock options, SARs, RSUs, and PSUs vested during the six months ended June 30, 2019 and 2018 was $2.9 million and $0.8 million , respectively. For the six months ended June 30, 2019 and 2018 , the total cash received from the exercise of stock options under the Plans was $0.0 million and $0.0 million , respectively. The following table summarizes information about SARs outstanding at June 30, 2019 . There were no options outstanding as of June 30, 2019 .

In estimating the fair value of the share-based awards outstanding at June 30, 2019 and December 31, 2018 , the Company employed the Black-Scholes option pricing model with assumptions detailed below. June 30, December 31, Expected term 2.5 to 9.5 years 3.0 to 10.0 years Expected volatility weighted-average 22.02 % 22.14 % Expected dividend yield 0.14 % 0.12 % Risk-free rate weighted-average 1.87 % 2.58 % 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 option/SARs expected exercise date. The pre-tax compensation cost/(benefit) recognized in the financial statements related to these plans was $0.1 million and $(1.4) million for the three and six months ended June 30, 2019 and $1.3 million and $0.7 million for the three and six months ended June 30, 2018 , respectively. The related tax expense/(benefit) recognized was $0.0 million and $0.3 million for the three and six months ended June 30, 2019 and $(0.3) million and $(0.1) million for the three and six months ended June 30, 2018, respectively. As of June 30, 2019 , the total compensation cost related to non-vested share-based awards not yet recognized was $3.8 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. 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 challenges the directors’ oversight of insurance sales to non-U.S. residents and alleges 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 are 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 has appealed the Court’s Final Judgment and that appeal is pending before the First District Court of Appeals in Houston, TX. In April of 2019, National Western defended a two week jury trial in which it was alleged that the Company 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 the Company in the amount of $14,949 for economic damages and $2.92 million in non-economic and punitive damages. Plaintiff also intends to pursue an award of attorney's fees and costs in the amount of approximately $1 million . The Company intends to vigorously dispute the verdicts and the amounts awarded, and in furtherance of such has filed a Motion for Judgment Notwithstanding Jury Verdict and a Motion for New Trial, and will protect its appellate rights. 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 National Western 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 cooperated 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 $14.5 million in commitments to fund new loans and $0.4 million in commitments to extend credit relating to existing loans at June 30, 2019 . The Company evaluates each customer's creditworthiness on a case-by-case basis.

It is the Company's policy to initiate disposals of debt securities in the held to maturity category only in instances in which the credit status of the issuer comes into question and the realization of all or a significant portion of the investment principal of the holding is deemed to be in jeopardy. Net real estate gains for the six months ended June 30, 2019 primarily pertain to the Company's sale of its nursing home operations in Reno, Nevada and San Marcos, Texas as well as a property sold located in Austin, Texas. The sale of the Reno nursing home was completed effective February 1, 2019 and a gain of $5.7 million was realized on the sale of the land and building associated with the operation. The sale of the San Marcos nursing home was concluded effective May 1, 2019 and the Company recorded a loss of $(2.0) million associated with the sale of the land and building of this operation (an impairment loss on this property of $(2.2) million was recorded in the quarter ended March 31, 2019). The sale of the Company's prior home office completed effective June 7, 2019 realized a gain on the sale of $3.2 million . The Company uses the specific identification method in computing realized gains and losses. For the three months ended June 30, 2019 and 2018 the percentage of gains on bonds due to the call of securities was 89.4% and 99.0% , respectively. For the six months ended June 30, 2019 and 2018 the percentage of gains on bonds due to the call of securities was 72.6% and 99.7% , respectively.

Based on its review, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2019 . The Company monitors the investment portfolio on an ongoing basis for any changes in issuer facts and circumstances that could result in future impairments. During the three and six months ended June 30, 2019 , the Company recorded $5.9 million in other-than-temporary impairments on debt securities on Weatherford International bonds. Weatherford International announced its intention to file Chapter 11 bankruptcy on May 10, 2019 which caused its market price to drop considerably. Subsequently, on July 1, 2019, Weatherford filed for bankruptcy. Unrealized losses for debt securities held to maturity and debt securities available for sale decreased during the first six months of 2019 primarily due to the downward movement in market interest rates during this period (which increases the market price of debt securities). Debt Securities balances at June 30, 2019 include Ozark National holdings of $289.7 million in held to maturity and $403.8 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 January 31, 2019. The following table shows the gross unrealized losses and fair values of the Company's held to maturity debt securities by investment category and length of time the individual securities have been in a continuous unrealized loss position at June 30, 2019 .

The gross unrealized losses for debt securities are made up of 63 individual issues, or 4.1% of the total debt securities held by the Company at June 30, 2019 . The market value of these bonds as a percent of amortized cost approximates 97.9% . Of the 63 securities, 52 , or 82.5% , fall in the 12 months or greater aging category; and 59 were rated investment grade at June 30, 2019 . The amortized cost and fair value of investments in debt securities at June 30, 2019 , 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.

(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 is 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 and also by the borrower. 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. 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, 2019 or 2018 and as a result all interest income was recognized at June 30, 2019 and 2018 . The following table represents the mortgage loan portfolio by loan-to-value ratio.

Appraisals are required at the time of funding and may be updated if a material change occurs from the original loan agreement. 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. Mortgage loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. When it is determined that a loan is impaired, a loss is recognized for the difference between the carrying amount of the mortgage loan and the estimated value reduced by the cost to sell. Estimated value is typically based on the loan's observable market price or the fair value of the collateral less cost to sell. Impairments and changes in the valuation allowance are reported in net realized investment gains (losses) in the Condensed Consolidated Statements of Earnings. The following table represents the mortgage loan allowance for the periods shown.

Included in the amount at June 30, 2019 is a surface parking property owned by Ozark National which it leases. The value of this real estate investment was appraised at $4.3 million at January 31, 2019 as part of the purchase accounting done as of that date. The Company recognized operating income on real estate properties of approximately $1.4 million and $1.1 million for the first six months of 2019 and 2018

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). 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. The Company’s Level 3 liabilities consist of share-based compensation obligations, certain product-related embedded derivatives, and contingent consideration in the acquisition of businesses. 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, 2019 Total Level 1 Level 2 Level 3 (In thousands) Debt securities, available for sale $ 3,375,105 — 3,375,105 — Equity securities 19,324 19,324 — — Derivatives, index options 89,900 — — 89,900 Total assets $ 3,484,329 19,324 3,375,105 89,900 Policyholder account balances (a) $ 100,638 — — 100,638 Other liabilities (b) 11,862 — — 11,862 Total liabilities $ 112,500 — — 112,500 During the three and six months ended June 30, 2019 , the Company made no transfers into or out of Levels 1, 2 or 3.

Unrealized gains (losses) on available for sale debt securities are reported as other comprehensive income (loss) within the stockholders' equity section of the Condensed Consolidated Balance Sheet. Effective January 1, 2018, the change in fair value of equity securities is reported in the Condensed Consolidated Statement of Earnings as net investment income. The fair value hierarchy classifications are reviewed each reporting period. Reclassification of certain financial assets and liabilities may result based on changes in the observability of valuation attributes. Reclassifications are reported as transfers into and out of Level 3 at the beginning fair value for the reporting period in which the changes occur.

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]
Derivative Investments	DERIVATIVE INVESTMENTS 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.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS Effective January 31, 2019, the Company acquired Ozark National Life Insurance Company (“Ozark National”) and N.I.S. Financial Services, Inc. (“NIS”) following the receipt of regulatory approvals. NWLGI and National Western paid cash in an aggregate amount of approximately $205.4 million in exchange for all of the outstanding stock of Ozark National (wholly owned by National Western) and NIS (wholly owned by NWLGI). In addition to the cash price paid, National Western has a contingent liability for an "earn-out payment" based upon the persistency of Ozark National's in force business that was acquired achieving thresholds as specified in the Stock Purchase Agreement ("Agreement"). The earn-out payment from the Company to the seller per the Agreement has a maximum limit of $5.0 million . Using a probabilistic method for valuing contingent consideration, the Company at January 31, 2019 recorded a liability of $3.7 million representing the estimated fair value of the additional consideration estimated to be paid as part of the acquisition. The contingent consideration was subsequently reported at its fair value of $3.9 million as of June 30, 2019, with changes in fair value running through general expenses. In addition to the purchase price, the Company incurred $3.2 million of acquisition-related costs in 2019, and an additional $1.0 million in acquisition-related costs during the year ended December 31, 2018. In accordance with GAAP, these costs are included in other operating expenses in the Condensed Consolidated Statements of Earnings and are not considered a part of the purchase price. The acquisition has been accounted for in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations . Purchase accounting, as defined by ASC 805, requires that the assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The fair values shown below were determined based on management’s best estimates, employing fair valuation methodologies commonly utilized in preparing financial statements in accordance with GAAP, and are subject to revision for one year following the acquisition date. The excess of the purchase price paid above net tangible assets acquired has been assigned to intangible assets and goodwill. The following table presents the fair values of the net assets acquired as of January 31, 2019. January 31, 2019 Assets Fair value (In thousands) Debt securities held to maturity $ 261,059 Debt securities available for sale 400,719 Policy loans 28,128 Real estate 4,600 Cash and cash equivalents 16,275 Accrued investment income 6,116 Value of business acquired 145,768 Reinsurance recoverables 21,895 Other intangible assets 9,600 Other assets acquired 12,075 Total assets acquired 906,235 Liabilities Traditional life reserves 691,297 Other policyholder liabilities 13,867 Other liabilities acquired 5,840 711,004 Net identifiable assets acquired 195,231 Goodwill 13,864 Net assets acquired $ 209,095 Identifiable Intangible Assets The following table presents the fair value of identifiable intangible assets acquired at January 31, 2019: Fair Value Weighted-Average Amortization Period (In thousands) Trademarks / trade names $ 2,800 15 Internally developed software 3,800 7 Insurance licenses 3,000 NA $ 9,600 The value of trademarks was estimated using the relief from royalty method, based on the assumption that in lieu of ownership, an organization would be willing to pay a royalty in order to receive the related benefits of using the brand. 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. These identified intangible assets will be amortized using a straight-line method over their respective amortization periods and will be reviewed annually for impairments. Value of Business Acquired ("VOBA") VOBA is a purchase accounting convention for life insurance companies in business combinations based upon an actuarial determination of the difference between the fair value of policyholder liabilities acquired and the same policyholder liabilities measured in accordance with the acquiring company's accounting policies. The difference, referred to as VOBA, is an intangible asset subject to periodic amortization. As of the January 31, 2019 acquisition date, the VOBA balance recorded was $145.8 million . Based upon the remaining unamortized balance as of June 30, 2019, the expected amortization for the next five years is as follows: Expected Amortization (In thousands) Remainder of 2019 $ 4,596 2020 $ 8,725 2021 $ 8,282 2022 $ 7,897 2023 $ 7,552 Financial Information Subsequent to the acquisition date of January 31, 2019, Ozark National and NIS total revenues of $48.4 million and net earnings of $7.2 million have been included in Condensed Consolidated Statements of Earnings for the quarter and five months ended June 30, 2019 . These results for segment reporting purposes have been combined in the Acquired Businesses segment. The following unaudited comparative pro forma total revenues and net earnings represent Condensed Consolidated Results of Operations for the Company which assume amounts estimated had the acquisition of Ozark National and NIS by the Company been effective January 1, 2018.

Accounting Policies [Abstract]
New Accounting Pronouncements	Recent accounting pronouncements not yet adopted On April 25, 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 various aspects of the following guidance previously issued related to financial instruments, based on feedback from stakeholders. A. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Areas for improvement . The amendments clarify guidance and implementation around accrued interest, transfers between classifications or categories for loans and debt securities, consideration of recoveries in estimating allowances, reinsurance recoveries, consideration of prepayments and estimated costs to sell when foreclosure is probable. Additionally, the amendments correct certain cross-references. B. ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Liabilities. The amendments clarify the scope of the original Update, and add clarification on the guidance and implementation around fair value disclosure requirements for nonpublic entities, measurement alternatives for equity securities without readily determinable fair values at nonrecurring fair value measurement, remeasurement of equity securities without readily determinable fair values at historical exchange rates, and associated disclosure requirements. C. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments clarify the guidance and implementation around partial-term fair value hedges of interest rate risk, amortization of fair value hedge basis adjustments, disclosure of fair value hedge basis adjustments, consideration of the hedged contractually specified interest rate under the hypothetical derivative method, scope for nonpublic entities, and application of a first-payments-received cash flow hedging technique to overall cash flows on a group of variable interest payments. The amendments contained in this update will be effective for the same fiscal years in which the original ASU becomes effective, or, if already implemented, annual periods beginning after the issuance of this update. The Company will be primarily affected by the clarifications provided to ASU 2016-13, which is still pending adoption. 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 periods beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. In August 2018, the FASB issued a new Concepts Statement No. 8 Conceptual Framework for Financial Reporting - Chapter 8, Notes to Financial Statements . This was issued as part of a disclosure framework project aimed at improving disclosures in financial statements. This issuance provides conceptual guidance that may be followed when determining items to include as disclosures in the notes to financial statements. In conjunction with this issuance, the FASB also issued two accounting standard updates (“ASU”) which identified a particular FASB Topic and evaluated its disclosures through the new conceptual framework of Concepts Statement No. 8, Chapter 8. This process resulted in the issuance of the following two ASUs. In August 2018, FASB issued ASU 2018-13 F air Value Measurement (Topic 820) Disclosure Framework - Changes to the Disclosure requirements for Fair Value Measurement. This update removed disclosures for 1) amount of and reasons for transfers between Level 1 and Level 2 for fair value hierarchy, 2) policy for timing of transfers between levels, 3) valuation process for Level 3 fair value measurements. This update also added disclosure requirement as follows: 1) changes in unrealized gains and losses for the period included in OCI for recurring Level 3 fair value measurements held at end of reporting period; 2) range and weighted average (or other reasonable quantitative measurement) of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments will be effective for interim periods beginning after December 15, 2019. Adoption of the guidance is not expected to have a material effect on the Company’s results of operations or financial position. In August 2018, FASB issued ASU 2018-14 Compensation-Retirement Benefits - Defined Benefit Plans-General (Subtopic 715-20) Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans . This update removed disclosures for 1) amounts in AOCI expected to be recognized as components of net periodic benefit cost over the next fiscal year, 2) amount and timing of plan assets expected to be returned to the employer, 3) related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan, 4) the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of the net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. This update also added disclosures as follow: 1) weighted-average interest crediting rates for cash balance plans and other plans with promised crediting rates, 2) explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. Finally, this update clarified that the following information for defined benefit pension plans should be disclosed: 1) projected benefit obligation (PBO) and fair value of plan assets for plans with PBO in excess of plan assets, 2) accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments will be effective for fiscal periods ending after December 31, 2020. Adoption of the guidance is not expected to have a material effect on the Company’s results of operations or financial position. 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. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of 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. The guidance is 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 income. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements. Recent accounting pronouncements adopted In August 2018, the SEC released a final rule updating disclosure requirements, Disclosure Update and Simplification, which resulted in the additional interim disclosure of an analysis of changes in stockholders’ equity to be required for the current and comparative quarter and year-to-date interim periods. Registrants are required to provide an analysis of changes in each caption of stockholders’ equity and noncontrolling interests, which will be accompanied by dividends per share and in the aggregate for each class of shares. The disclosure must be presented in the form of a reconciliation, either as a separate statement or in the footnotes. The adoption of this ASU in 2019 did not have a material effect on the results of operations or financial position of the Company as this information in year-to-date format is already provided. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities , which amends the amortization period for certain purchased callable debt securities held at a premium. The amortization period for premiums is being shortened to the earliest call date. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The adoption of this ASU in 2019 did not have a material effect on the results of operations or financial position of the Company. In February 2016, the FASB issued new guidance on leasing transactions (ASU 2016-02, Leases - Topic 842). The new guidance is effective for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and requires a modified retrospective transition approach (subject to optional practical expedients). The new guidance requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months. Leases would be classified as finance or operating leases and both types of leases will be recognized on the balance sheet. Lessor accounting will remain largely unchanged from current guidance except for certain targeted changes. The new guidance will also require new qualitative and quantitative disclosures. Early adoption is permitted. The Company elected to early adopt this guidance in 2018. There was no material impact to the Company’s financial position, results of operations or cash flows as the result of the adoption of this ASU in 2018. 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.
