Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Basis of Presentation	CONSOLIDATION AND BASIS OF PRESENTATION On October 1, 2015, National Western Life Insurance Company ("National Western", "NWLIC", or "company") completed its previously announced holding company reorganization. As a result of the reorganization, National Western became a wholly owned subsidiary of National Western Life Group, Inc. ("NWLGI"), a Delaware Corporation, and NWLGI replaced National Western as the publicly held company. 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 NWLGI and its subsidiaries (“Company”) as of June 30, 2016 , and the results of its operations and its cash flows for the three and six months ended June 30, 2016 and 2015 . Such adjustments are of a normal recurring nature. The results of operations for the six months ended June 30, 2016 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, 2015 and are 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, 2015 has been derived from the audited consolidated financial statements as of that date. Prior to the reorganization, the accompanying consolidated financial statements included the accounts of National Western and its wholly owned subsidiaries: The Westcap Corporation, Regent Care San Marcos Holdings, LLC, NWL Investments, Inc., NWL Services, Inc., NWLSM, Inc., and NWL Financial, Inc. During the fourth quarter of 2015, subsequent to the reorganization, National Western transferred ownership of Regent Care San Marcos Holdings, LLC, NWL Investments, Inc., and NWL Services, Inc. to NWLGI via a dividend transaction resulting in those entities becoming wholly owned subsidiaries of NWLGI. 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. 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, 2016 and 2015 .

Accounting Policies [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS In June 2014, the Financial Accounting Standards Board ("FASB") issued guidance that applies to all reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. It requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and follows existing accounting guidance for the treatment of performance conditions. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company adopted this standard during the three month period ended March 31, 2016. The adoption of this standard did not have a material impact on the Company’s financial position, results of operations or cash flows. In January 2016, the FASB released accounting standards update 2016-01 Recognition and Measurement of Financial Assets and Liabilities. The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. The provisions of this update become effective for interim and annual periods beginning after December 15, 2017. The Company does not expect the requirements of this update to have a material impact on the Company’s financial position, results of operations or cash flows. In June 2016, the FASB released accounting standards update 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. Adoption of the guidance is not expected to have a material effect on the Company’s results of operations or financial position. 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

Stockholders' Equity	6 Months Ended
	Jun. 30, 2016
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 greater of statutory earnings from operations excluding capital gains or 10% of statutory surplus of the company. The maximum dividend payment which may be made without prior approval in 2016 is $117.1 million . National Western did not declare or pay cash dividends on its common stocks during the six months ended June 30, 2016 and 2015. As discussed in Note 1, Consolidation and Basis of Presentation, on October 1, 2015, NWLIC completed its previously announced holding company reorganization and became a wholly owned subsidiary of NWLGI. While remaining under the same Colorado Division of Insurance restrictions pertaining to dividend amounts, dividends declared by NWLIC from that date forward are payable entirely to NWLGI as the sole owner of NWLIC. The reorganization effective October 1, 2015 provided for the conversion of each share of Class A common stock, par value $1.00 per share, and each share of Class B common stock, par value $1.00 per share, of NWLIC issued and outstanding immediately prior to the effective time of the merger, into one duly issued, fully paid and non-assessable share of Class A common stock, par value $0.01 per share, and Class B common stock, par value $0.01 per share, of NWLGI. Consequently, NWLGI replaced NWLIC as the publicly held company and is the successor issuer to NWLIC.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share of common stock are computed by dividing net income by the weighted-average basic common shares outstanding during the period. Diluted earnings per share assumes the issuance of common shares applicable to stock options in the denominator. Net income for the periods shown 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 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).

Compensation and Retirement Disclosure [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 complies 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. Fair values of plan assets and liabilities are measured as of the prior December 31 for each respective year. The following table summarizes the components of net periodic benefit cost. Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 (In thousands) Service cost $ 27 51 53 102 Interest cost 250 246 500 492 Expected return on plan assets (304 ) (330 ) (608 ) (660 ) Amortization of prior service cost — 1 — 2 Amortization of net loss 193 196 386 392 Net periodic benefit cost $ 166 164 331 328 The service costs shown in the above table represent 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 2016 plan year is $0.2 million . There was no remaining contribution payable for the 2015 plan year as of June 30, 2016 . As of June 30, 2016 , the company had contributed a total of $0.1 million to the plan for the 2016 plan year. National Western also sponsors a nonqualified defined benefit plan primarily for senior officers. The plan provides benefits based on the participants' years of service and compensation. The 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"). 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 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 nonqualified defined benefit plan for the benefit of the then Chairman and the President 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 nonqualified defined benefit plan, while complying with the requirements of the Act. The following table summarizes the components of net periodic benefit costs for the then Chairman and President's nonqualified defined benefit plans.

Disclosure of Compensation Related Costs, Share-based Payments [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, 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 stock appreciation rights ("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, $0.01 par value, 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 reorganization. All of the employees of the Company and its subsidiaries are eligible to participate in the current 2008 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. Employee grants vest 20% annually following three years of service following the grant date. Directors' 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 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. On February 17, 2016, the Company granted 14,643 SARs to officers of National Western at the closing market price per Class A common share of $216.48 . These SARs, unlike prior grants, will vest annually at a rate of 33.3% per year from the date of grant. No stock option or SAR awards were issued during the first six months of 2015. While not previously utilized, the 2008 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 commons 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. 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. On February 17, 2016, the Company granted 5,727 performance stock units and 3,661 restricted stock units to officers of National Western based upon the closing market price per Class A common share of $216.48 . Both the PSUs and RSUs vest three years from the date of grant. The RSUs are payable in cash at the vesting date equal to the closing price of the Company's Class A common share at that time. For PSUs, the performance period begins the first day of the calendar year, in this case January 1, 2016, and runs three 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. On April 14, 2016, the Company granted 2,563 restricted stock units to directors of NWLGI, based upon the closing market price per Class A common share of $226.84 . The RSUs vest one year from the date of grant, and are payable in cash at the vesting date equal to the closing price of the Company's Class A common share at that time. The Company uses the current fair value method to measure compensation cost. As of June 30, 2016 and 2015 , the liability balance was $4.8 million and $7.3 million , respectively. A summary of shares available for grant and activity is detailed below.

Forfeited stock options, if any, are not shown as being added back to the "Shares Available For Grant" balance as they were awarded under the 1995 Plan which was terminated during calendar year 2010. The total intrinsic value of SARs exercised was $0.0 million and $0.4 million for the six months ended June 30, 2016 and 2015 , respectively. The total share-based liabilities paid for the exercised SARs were $0.0 million and $0.4 million for the six months ended June 30, 2016 and 2015 , respectively. The total fair value of stock options and SARs vested during the six months ended June 30, 2016 and 2015 was $0.3 million and $0.6 million , respectively. For the six months ended June 30, 2016 and 2015 , 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 stock options and SARs outstanding at June 30, 2016 . Options/SARs Outstanding Number Outstanding Weighted- Average Remaining Contractual Life Number Exercisable Exercise prices: 255.13 (options) 20,768 1.8 years 20,768 208.05 (options) 7,000 2.0 years 7,000 114.64 (SARs) 23,168 2.6 years 23,168 132.56 (SARs) 27,918 5.5 years 13,508 210.22 (SARs) 34,000 7.5 years 3,600 216.48 (SARs) 14,461 9.6 years — Totals 127,315 68,044 Aggregate intrinsic value (in thousands) $ 3,619 $ 2,715 The aggregate intrinsic value in the table above is based on the closing stock price of $ 195.27 per share on June 30, 2016 . In estimating the fair value of the share based awards outstanding at June 30, 2016 and December 31, 2015 , the Company employed the Black-Scholes option pricing model with assumptions detailed below. June 30, December 31, Expected term of options 1.8 to 9.6 years 2.3 to 8.0 years Expected volatility: Range 22.53% to 28.81% 21.11% to 37.77% Weighted-average 23.83 % 23.89 % Expected dividend yield 0.18 % 0.14 % Risk-free rate: Range 0.54% to 1.52% 0.22% to 1.67% Weighted-average 1.03 % 0.63 % The Company reviewed the contractual term relative to the options 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’s expected exercise date. The pre-tax compensation cost (benefit) recognized in the financial statements related to the two plans defined above was $(1.3) million and $(2.8) million for the three and six months ended June 30, 2016, and $(0.8) million and $(1.6) million for the three and six months ended June 30, 2015, respectively. The related tax (expense)/benefit recognized was $0.5 million and $1.0 million for the three and six months ended June 30, 2016 and to $0.3 million and $0.6 million for the three and six months ended June 30, 2015 , respectively. As of June 30, 2016 , the total compensation cost related to nonvested share based awards not yet recognized was $3.7 million . This amount is expected to be recognized over a weighted-average period of 1.6 years . The Company recognizes compensation cost over the graded vesting periods.

Commitments and Contingencies

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 October 26, 2011 the Brazilian Superintendence of Private Insurance (“SUSEP”) attempted to serve National Western with a subpoena regarding an administrative proceeding initiated by SUSEP in which it alleged that National Western was operating as an insurance company in Brazil without due authorization. National Western had been informed that SUSEP was attempting to impose a penal fine, based on currency exchange rates at that time, of approximately $6.0 billion on the company. SUSEP unsuccessfully attempted to serve National Western with notice regarding this matter. National Western does not transact business in Brazil and has no officers, employees, property, or assets in Brazil. National Western believes that SUSEP has no jurisdiction over the company, that SUSEP's attempts at service of process were invalid, and that any penal fine would be unenforceable. In addition, a new law recently enacted in Brazil would limit the amount of any penal fine to 3 million reais (approximately $800,000 based on current exchange rates). For the reasons described above, the Company does not believe that this matter meets the definition of a material pending legal proceeding as such term is defined in Item 103 of Regulation S-K but has included the foregoing description solely due to the purported amount of the fine sought at that time. Nonetheless, National Western is in discussions with SUSEP in an effort to resolve this matter. No conclusion can be drawn at this time as to the outcome of these discussions, or whether they will continue, or how any such outcome may impact the Company’s business, results of operations, or financial condition. However, in light of the pendency of discussions with Brazilian authorities, National Western has ceased accepting new applications from residents in Brazil. National Western was the named defendant in the case of Damaris Maldonado Vinas, et al. vs. National Western Life Insurance , in which the plaintiffs, after National Western had paid the death benefits to the beneficiary (Francisco Iglesias-Alvarez) upon the annuitant’s (Carlos Iglesias-Alvarez) death, sought to annul two annuity policies issued by National Western at the behest of Carlos Iglesias-Alvarez and which named Francisco Iglesias-Alvarez as their beneficiary. On March 31, 2016, the United States District Court for the District of Puerto Rico (the “Court”) issued its Opinion and Order on the pending Motions for Summary Judgment submitted by the parties, and therein denied National Western’s motion and granted plaintiffs’ motion voiding the two annuities and requesting a refund of the premiums paid ( $2.9 million ). National Western vigorously defended the case and believes that the Court’s Opinion and Order is contrary to applicable law. As such, National Western filed a Motion for Reconsideration of Opinion and Order and Corresponding Judgment with the Court on April 27, 2016, which the Court denied on May 5, 2016. National Western filed a Notice of Appeal on May 31, 2016. 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, the Brazilian authorities have 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 has issued a subpoena upon the company 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 is 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 $20.0 million commitments to fund new loans and $1.2 million commitments on existing loans to extend credit relating to loans at June 30, 2016 . The Company evaluates each customer's creditworthiness on a case-by-case basis.

(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. Mortgage, equity, participation and mezzanine loans on real estate are considered financing receivables reported by the Company. 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, 2016 or 2015 and as a result all interest income was recognized at June 30, 2016 and 2015 .

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.

The Company recognized operating income on real estate properties of approximately $1.3 million for the first six months of 2016 . In addition, the Company recorded a net realized investment gain on disposed properties located in Brazoria County (Texas), Ruidoso, New Mexico, and Austin, Texas, totaling $2.9 million during the first six months of 2016.

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 the required 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), and preferred stock. 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 the Company’s Level 3 liabilities consist of share-based compensation obligations and certain 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, 2016 Total Level 1 Level 2 Level 3 (In thousands) Debt securities, available for sale $ 3,011,002 — 3,011,002 — Equity securities, available for sale 19,657 19,267 390 — Derivatives, index options 63,319 — — 63,319 Total assets $ 3,093,978 19,267 3,011,392 63,319 Policyholder account balances (a) $ 76,237 — — 76,237 Other liabilities (b) 4,819 — — 4,819 Total liabilities $ 81,056 — — 81,056 During the three and six months ended June 30, 2016 , the Company had no transfers into or out of Levels 1, 2 or 3.

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 which further reduces the Company's credit exposure.
