Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	(A) Principles of Consolidation. The accompanying consolidated financial statements include the accounts of National Western Life Insurance Company and its wholly owned subsidiaries (“National Western” or "Company"). The wholly owned subsidiaries consist of The Westcap Corporation, Regent Care San Marcos Holdings, LLC, NWL Investments, Inc., NWL Services, Inc., NWLSM, Inc., and NWL Financial, Inc.  All significant intercorporate transactions and accounts have been eliminated in consolidation.
	(B) Basis of Presentation.  The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") which require 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 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) commitments and contingencies, (5) valuation allowances for deferred tax assets, (6) other-than-temporary impairment losses on debt securities, 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 years ended December 31, 2014, 2013 and 2012.

	Net Earnings		$	5,000			3,061			4,504
	The Company also files financial statements with insurance regulatory authorities which are prepared on the basis of statutory accounting practices prescribed or permitted by the Colorado Division of Insurance which are significantly different from consolidated financial statements prepared in accordance with GAAP.  These differences are described in detail in the statutory information section of this note.
	Certain amounts in the prior year consolidated financial statements have been reclassified to conform to the current year presentation.
	(C) Investments. Investments in debt securities the Company purchases with the intent to hold to maturity are classified as securities held to maturity. The Company has the ability to hold the securities until maturity, as it would be unlikely that forced sales of securities would be required, prior to maturity, to cover payments of liabilities. As a result, securities held to maturity are carried at amortized cost less declines in fair value that are deemed other-than-temporary.
	Investments in debt and equity securities that are not classified as securities held to maturity are reported as securities available for sale. Securities available for sale are reported in the accompanying consolidated financial statements at fair value.  Valuation changes resulting from changes in the fair value of the securities are reflected as a component of stockholders' equity in accumulated other comprehensive income (loss).  These unrealized gains or losses in stockholders' equity are reported net of taxes and adjustments to deferred policy acquisition costs.
	Transfers of securities between categories are recorded at fair value at the date of transfer.
	Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method.  For mortgage-backed and asset-backed securities, the effective interest method is used based on anticipated prepayments and the estimated economic life of the securities.  When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments.  The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied at the time of acquisition.  This adjustment is reflected in net investment income.
	Quarterly the Company reviews its investment portfolio for market value changes to identify changes caused by issuer credit deterioration, changes in market interest rates and changes in economic conditions.  If this review indicates a decline in fair value that is other-than-temporary, the Company’s carrying amount in the investment is reduced to its estimated fair value.  In accordance with GAAP guidance the estimated credit versus non-credit components are bifurcated.  The credit component is taken through earnings.  The non-credit component is reclassified as unrealized loss in other comprehensive income.  The Company would not recognize impairment of securities due to changing of interest rates or market dislocations unless the Company had the intent to sell the securities prior to recovery or maturity.
	The Company considers a number of factors in determining whether the impairment is other-than-temporary.  These include, but are not limited to:  1) actions taken by rating agencies, 2) default by the issuer, 3) the significance of the decline in fair value, 4) the intent and ability to hold the investment until recovery, 5) the time period during which the decline has occurred, 6) an economic analysis of the issuer’s industry, and 7) the financial strength, liquidity, and recoverability of the issuer.  Management performs a security-by-security review each quarter in evaluating the need for any other-than-temporary impairments.  Although no set formula is used in this process, the investment performance, collateral position, and continued viability of the issuer are significant measures considered.
	Realized gains and losses for securities available for sale and securities held to maturity are included in earnings and are derived using the specific identification method for determining the cost of securities sold or called.  Decline in the fair value below cost that is deemed other-than-temporary is bifurcated in credit and non-credit declines.  The noncredit related declines are reclassified as unrealized losses in accumulated other comprehensive income (loss).  Credit losses are recorded in earnings and result in the establishment of a new cost basis for the security.  The new discount or reduced premium amount is amortized over the remaining life of the impaired debt security prospectively based on the amount and timing of future estimated cash flows.
	Mortgage loans and other long-term investments are stated at cost, less unamortized discounts, deferred fees, and allowances for possible losses. Policy loans are stated at their aggregate unpaid balances. Real estate is stated at the lower of cost or fair value less estimated costs to sell.
	Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected.  The Company has identified these loans through its normal loan review procedures.  Impaired loans include: 1) nonaccrual loans, 2) loans which are 90 days or more past due, unless they are well secured and are in the process of collection, and 3) other loans which management believes are impaired.  Impaired loans are measured based on: 1) the present value of expected future cash flows discounted at the loan's effective interest rate, 2) the loan's observable market price, or 3) the fair value of the collateral if the loan is collateral dependent.  Substantially all of the Company's impaired loans are measured at the fair value of the collateral.  In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent.
	While the Company closely manages its investment portfolio, future changes in issuer facts and circumstances can result in impairments beyond those currently identified.
	(D) Cash and Cash Equivalents. For purposes of the consolidated statements of cash flows, the Company considers all short-term investments with a maturity at the date of purchase of three months or less to be cash equivalents.
	(E) Derivatives.   Fixed-index products combine features associated with traditional fixed annuities and universal life contracts, with the option to have interest rates linked in part to an underlying equity index.  The equity return component of such policy contracts is identified separately and accounted for in future policy benefits as embedded derivatives on the consolidated balance sheet.  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.  The host contracts are recorded as discounted debt instruments that are 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 index annuity and life products.  The amounts which may be credited to policyholders are linked, in part, to the returns of the underlying index. The index options act as hedges to match closely the returns on the underlying index.  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 is paid to the Company based on the underlying index performance and terms of the contract.  As a result, amounts credited to policyholders' account balances are substantially offset by changes in the value of the options.
	The Company does not elect hedge accounting relative to derivative instruments. The derivatives are reported at fair value in the accompanying consolidated financial statements.  Changes in the values of the index options and changes in the policyholder liabilities are both reflected in the statement 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 statement of earnings.  Any changes relative to the embedded derivatives associated with policy contracts are reflected in contract interest in the consolidated statement of earnings.
	Although there is credit risk in the event of nonperformance by counterparties to the index options, the Company does not expect any 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.  At December 31, 2014 and 2013, the fair values of index options owned by the Company totaled $114.3 million and $169.3 million, respectively.
	(F) Insurance Revenues and Expenses. Premiums on traditional life insurance products are recognized as revenues as they become due from policyholders. Benefits and expenses are matched with premiums in arriving at profits by providing for policy benefits over the lives of the policies and by amortizing acquisition costs over the premium-paying periods of the policies. For universal life and annuity contracts, revenues consist of policy charges for the cost of insurance, policy administration, and surrender charges assessed during the period.  Expenses for these policies include interest credited to policy account balances, benefit claims incurred in excess of policy account balances and amortization of deferred policy acquisition costs and deferred sales inducements.
	Under GAAP, commissions, sales inducements, and certain expenses related to policy issuance and underwriting, all of which vary with and are related to the production of new business, are deferred. For traditional products, these costs are amortized over the premium-paying period of the related policies in proportion to the ratio of the premium earned to the total premium revenue anticipated, using the same assumptions as to interest, mortality, and withdrawals as were used in calculating the liability for future policy benefits. For universal life and annuity contracts, these costs are amortized in relation to the present value of expected gross profits on these policies.  The Company evaluates the recoverability of deferred policy acquisition and sales inducement costs on a quarterly basis.  In this evaluation, the Company considers estimated future gross profits or future premiums, as applicable for the type of contract.  The Company also considers expected mortality, interest earned and credited rates, persistency, and expenses.
	A summary of information relative to deferred policy acquisition costs (DPAC) is provided in the table below.

	Amortization of deferred policy acquisition costs increased to $115.2 million in the year ended December 31, 2014 compared to $108.2 million reported in 2013.  Amortization expense in 2014 includes an unlocking adjustment to incorporate premium load increases implemented on several international life contracts which decreased DPAC amortization by $1.4 million. There were no unlocking adjustments in 2013 and 2012. DPAC true-up adjustments were also recorded in 2014, 2013 and 2012 relative to renewal trailer commissions, partial surrender rates, mortality rates, credited interest rates and earned rates for the current year’s experience resulting in a $7.2 million, $15.8 million and $12.8 million decrease in amortization expense in 2014, 2013 and 2012, respectively.
	Similar to deferred policy acquisition costs, amortization of deferred sales inducements include true-up and unlocking adjustments. Deferred sales inducement true-up adjustments were recorded in 2014, 2013, and 2012 of $1.6 million, $0.8 million and $5.5 million , respectively, each of which increased contract interest expense. There were no unlocking adjustments during these periods.
	Under GAAP, the liability for future policy benefits on traditional products has been calculated using assumptions as to future mortality (based on the 1965-1970, 1975-1980 and 2001 Select and Ultimate mortality tables), interest ranging from 3.25% to 8%, and withdrawals based on Company experience. For universal life and annuity contracts, the liability for future policy benefits represents the account balance. Fixed-index products combine features associated with traditional fixed annuities and universal life contracts, with the option to have interest rates linked in part to an equity index.  In accordance with GAAP guidance, the equity return component of such policy contracts must be identified separately and accounted for as embedded derivatives.  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 GAAP guidance provisions that require debt instrument type accounting.  The host contracts are recorded as discounted debt instruments that are accreted, using the effective yield method, to their minimum account values at their projected maturities or termination dates. The embedded derivatives are recorded at fair value.
	(G) Deferred Federal Income Taxes. Federal income taxes are accounted for under the asset and liability method.  Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  A valuation allowance for deferred tax assets is provided if all or some portion of the deferred tax asset may not be realized.  An increase or decrease in a valuation allowance that results from a change in circumstances that affects the realizability of the related deferred tax asset is included in income in the period the change occurs.
	(H) Depreciation of Property, Equipment, and Leasehold Improvements. Depreciation is based on the estimated useful lives of the assets and is calculated on the straight-line and accelerated methods.  Leasehold improvements are amortized over the lesser of the economic useful life of the improvement or the term of the lease.
	(I) Statutory Information. Domiciled in Colorado, the Company prepares its statutory financial statements in accordance with accounting practices prescribed or permitted by the Colorado Division of Insurance.  The Colorado Division of Insurance has adopted the provisions of the National Association of Insurance Commissioners' ("NAIC") Statutory Accounting Practices (“SSAP”) as the basis for its statutory accounting practices.
	The following are major differences between GAAP and accounting practices prescribed or permitted by the Colorado Division of Insurance (“statutory accounting practices”).
	1.  The Company accounts for universal life and annuity contracts based on the provisions of GAAP guidance.  The basic difference between GAAP guidance and statutory accounting practices with respect to certain long-duration contracts is that deposits for universal life and annuity contracts are not reflected as revenues, and surrenders and certain other benefit payments are not reflected as expenses.  Only contracts with no insurance risk qualify for such treatment under statutory accounting practices.  For all other contracts, statutory accounting practices do reflect such items as revenues and expenses.
	A summary of direct premiums and deposits collected is provided below.
		Years Ended December 31,
		2014				2013			2012
	(In thousands)
Annuity deposits	$	833,273			813,868			864,719
Universal life insurance deposits	280,980				296,286			248,118
Traditional life and other premiums	22,651				22,164			21,476
Totals	$	1,136,904			1,132,318			1,134,313
2.  Statutory accounting practices require commissions and related acquisition costs to be expensed as incurred, whereas under GAAP these items are deferred and amortized.
3.   For statutory accounting purposes, liabilities for future policy benefits for life insurance policies are calculated by the net level premium method or the commissioners reserve valuation method.  Future policy benefit liabilities for annuities are calculated based on the continuous commissioners annuity reserve valuation method and provisions of Actuarial Guidelines 33 and 35.
4.  Deferred Federal income taxes are provided for temporary differences which are recognized in the consolidated financial statements in a different period than for Federal income tax purposes.  Deferred taxes are also recognized in statutory accounting practices; however, there are limitations as to the amount of deferred tax assets that may be reported as admitted assets.  The change in the deferred taxes is recorded in surplus, rather than as a component of income tax expense.
5.  For statutory accounting purposes, debt securities are recorded at amortized cost, except for securities in or near default, which are reported at fair value.  Under GAAP, debt securities are carried at amortized cost or fair value based on their classification as either held to maturity or available for sale.
6.  Investments in subsidiaries are recorded as affiliated common stock investments at their respective SSAP investment value under statutory accounting, whereas the financial statements of the subsidiaries have been consolidated with those of the Company under GAAP.
7.  Compensation costs related to the Company’s share based compensation plans are recognized in income based on intrinsic value at each reporting date under statutory accounting, whereas under GAAP these costs are determined using the fair value method.
8.  The calculation of pension liabilities and net periodic benefit costs are recognized for both statutory and GAAP accounting.  Prior to January 1, 2013, in accordance with SSAP No. 89, the accumulated benefit obligation in excess of the fair value of plan assets, including unfunded accrued pension costs, was recognized in the statutory financial statements as an additional minimum liability with an equal amount recognized as a non-admitted intangible asset. Effective January 1, 2013, with the adoption of SSAP No. 102, statutory accounting pension liabilities are based upon the projected benefit obligation consistent with GAAP.
9.  The asset valuation reserve and interest maintenance reserve, which are investment valuation reserves prescribed by statutory accounting practices, have been eliminated, as they are not required under GAAP.
10. The table below provides the Company’s net gain from operations, net income, unassigned surplus (retained earnings) and capital and surplus (stockholders' equity), on the statutory basis used to report to regulatory authorities for the years ended December 31.
	2014				2013			2012
	(In thousands)
Net gain from operations before Federal and foreign income taxes	$	95,892			170,796			130,644
Net income	$	77,220			106,159			84,473
Unassigned surplus	$	1,141,579			1,082,519			961,054
Capital and surplus	$	1,185,643			1,126,232			1,004,766
(J) Stock Compensation. The Company accounts for its share-based compensation for GAAP reporting using liability accounting, and measures compensation cost using the fair value method at each reporting date.  For stock options, fair value is determined using an option pricing model that takes into account various information and assumptions including the Company's stock price, volatility, option price, vesting dates, exercise dates and projected option lapses.  Under the intrinsic value based method, compensation cost is the excess, if any, of the quoted market price of the stock at grant date or other measurement date over the amount an employee must pay to acquire the stock.
(K) Accounting Standards and Changes in Accounting
During February 2013, the Financial Accounting Standards Board ("FASB") issued new guidance related to the presentation of amounts reclassified out of accumulated other comprehensive income. The new guidance requires disclosure on the statement of income amounts reclassified. As the Company already reports reclassifications on its Consolidated Statements of Earnings and Consolidated Statements of Comprehensive Income (Loss), the new guidance did not have a significant impact on the Company's consolidated financial statements.
In July 2013, the FASB issued guidance to amend the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The new guidance states that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as reduction to deferred tax assets for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. This guidance is effective for annual reporting periods beginning on or after December 15, 2013 and interim periods within those annual periods. The Company adopted this guidance as of January 1, 2014 and the adoption did not have an effect on the deferred tax asset or liability classification on the Company's balance sheet and did not result in any additional disclosures to the financial statements.
In June 2014, the 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 will be effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company’s current employee share-based plans do not require performance targets and the adoption of this guidance is not expected to have a material impact on the Company’s financial position or results of operations.
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.

	The Company had real estate investments that were non-income producing for the preceding twelve months totaling $0.9 million, $1.3 million and $1.5 million at December 31, 2014, 2013 and 2012, respectively.
	(B)  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 balance sheet.
	In general, the Company originates loans on high quality, income-producing properties such as shopping centers, freestanding retail stores, office buildings, industrial and sales or service facilities, selected apartment buildings, motels, and health care facilities.  The location of these properties is typically in major metropolitan areas that offer a potential for property value appreciation. 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 proven to result in quality mortgage loans with few defaults.  Mortgage loan interest income is recognized on an accrual basis with any premium or discount amortized over the life of the loan.  Prepayment and late fees are recorded on the date of collection.
	The Company requires a minimum specified yield on mortgage loan investments.  The historically low interest rate environment of the past couple of years has resulted in fewer loan opportunities being available meeting the Company's required rate of return. Consequently, new mortgage loan origination activity has been less significant in this time frame with $37.1 million and $34.1 million in total loans for the years 2014 and 2013, respectively.
	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 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 has no loans past due 90 days which are accruing interest.
	The Company's direct investments in real estate are not a significant portion of its total investment portfolio as most of these investments were acquired through mortgage loan foreclosures.  The Company also participates in several real estate joint ventures and limited partnerships that invest primarily in income-producing retail properties.  These investments have generally served to enhance the Company's overall investment portfolio returns.
	The Company held net investments in mortgage loans totaling $149.5 million and $132.8 million at December 31, 2014 and 2013, respectively.  The diversification of the portfolio by geographic region, property type, and loan-to-value ratio was as follows:

(1)  Loan-to-Value Ratio using the most recent appraised value. Appraisals are required at the time of funding and may be updated if a material change occurs from the original loan agreement.
The greater than 90% category is related to loans made with a long standing borrower which are backed by the investment property, contracted leases and the guarantee of the borrower.
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 would indicate a potential problem are: 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 capital gains (losses) in the consolidated statements of earnings.
The Company recognized valuation losses of $0.0 million, $0.0 million and $0.7 million for the years ended December 31, 2014, 2013 and 2012, respectively.  The mortgage loan valuation write-down in 2012 represents a general valuation allowance established for the Company's mortgage loan portfolio based upon the Company's loss experience over the past ten years and is not specifically identified to individual loans. The impairments in 2012 were based on information which indicated that the Company may not collect all amounts in accordance with the mortgage agreement. While the Company closely monitors its mortgage loan portfolio, future changes in economic conditions can result in impairments beyond those currently identified.
The following table represents the mortgage loan allowance for the years ended December 31, 2014 and 2013:

The Company's real estate investments totaled approximately $16.7 million at December 31, 2014 and $18.2 million at December 31, 2013, and consist primarily of income-producing properties which are being operated by a wholly-owned subsidiary of the Company.  The Company’s real estate holdings are reflected in other long-term investments in the accompanying consolidated financial statements.  The Company records real estate at the lower of cost or fair value less estimated cost to sell, which is determined on an individual asset basis.  The Company recognized operating income on these properties of approximately $1.7 million, $1.7 million and $1.6 million for the years ended December 31, 2014, 2013 and 2012, respectively.  The Company monitors the conditions and market values of these properties on a regular basis and makes repairs and capital improvements to keep the properties in good condition. The Company recorded net realized investment gains on disposals of $1.0 million, $0.3 million and $2.6 million associated with these properties in the years ended December 31, 2014, 2013 and 2012, respectively.  The realized gains in 2014 were due to several properties being sold: one was an impaired and foreclosed property located in Steubenville, Ohio, another property was located in Houston, Texas and two were located in Freeport, Texas. The realized gain in 2012 was due to an impaired and foreclosed property located in New Orleans, LA that was subsequently sold at an amount above its impaired value.

The Company's investment policy is to invest in high quality securities with the primary intention of holding these securities until the stated maturity.  As such, the portfolio has exposure to interest rate risk which is the risk that funds are invested today at a market interest rate and in the future interest rates rise causing the current market price on that investment to be lower.  This risk is not a significant factor relative to the Company's buy and hold portfolio, since the original intention was to receive the stated interest rate and principal at maturity to match liability requirements to policyholders.  Also, the Company takes steps to manage these risks.  For example, the Company purchases the type of mortgage-backed securities that have more predictable cash flow patterns.
In addition, the Company is exposed to credit risk which is continually monitored.  Credit risk is the risk that an issuer of a security will not be able to fulfill their obligations relative to a security payment schedule.  The Company reviewed pertinent information for all issuers in an unrealized loss position at December 31, 2014 including market pricing history, credit ratings, analyst reports, as well as data provided by the issuers themselves.  The Company then made a determination on each specific issuer relating to other-than-temporary impairment.  For the securities that have not been impaired at December 31, 2014, the Company intends to hold these securities until recovery in fair value and expects to receive all amounts due relative to principal and interest.
The Company held below investment grade debt securities totaling $147.1 million and $178.6 million at December 31, 2014 and 2013, respectively. These amounts represent 1.5% and 1.9% of total invested assets for December 31, 2014 and 2013, respectively.  Below investment grade holdings are the result of downgrades subsequent to purchase, as the Company only invests in high quality securities with ratings quoted as investment grade.  Below investment grade securities generally have greater default risk than higher rated corporate debt.  The issuers of these securities are usually more sensitive to adverse industry or economic conditions than are investment grade issuers.
For the year ended December 31, 2014, the Company recorded net realized gains totaling $11.8 million related to the disposition of investment securities.  The net realized gains included $0.2 million of losses for other-than-temporary impairment write-downs on investments in debt and equity securities. For the years ended December 2013 and 2012, the Company recorded realized gains totaling $9.0 million and $14.5 million, respectively, related to disposition of securities.

Unrealized losses decreased in 2014 due to the decline in interest rates (which serves to increase market values).  The Company does not consider these investments to be other-than-temporarily impaired because the Company does not intend to sell these securities until recovery in fair value and expects to receive all amounts due relative to principal and interest.
The Company does not consider securities to be other-than-temporarily impaired where the market decline is attributable to factors such as market volatility, liquidity, spread widening and credit quality where we anticipate a recovery of all amounts due under the contractual terms of the security and have the intent and ability to hold until recovery or maturity.  Based on the Company’s review in concert with the Company’s ability and intent to hold these securities until maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2014. The Company will monitor the investment portfolio for future changes in issuer facts and circumstances that could result in future impairments beyond those currently identified.
Debt securities. The gross unrealized losses for debt securities are made up of 190 individual issues, or 14.5% of the total debt securities held by the Company. The market value of these bonds as a percent of amortized cost averages 97.8%.  Of the 190 securities, 148, or approximately 77.5%, fall in the 12 months or greater aging category; and 186 were rated investment grade at December 31, 2014.
Equity securities. The gross unrealized losses for equity securities are made up of 16 individual issues. These holdings are reviewed quarterly for impairment. Four of the equity securities were other-than-temporarily impaired at December 31, 2014, in accordance with Company policy.

Due to significant credit deterioration, one bond from the held to maturity portfolio was sold in both 2013 and 2012. The sale in 2013 resulted in an insignificant realized gain. The sale in 2012 resulted in a loss of $0.3 million. No transfers were made out of the held to maturity portfolio to the available for sale portfolio in 2014, 2013 and 2012.
Except for U.S. government agency mortgage-backed securities, the Company had no other investments in any entity in excess of 10% of stockholders' equity at December 31, 2014 or 2013.

For the years ended December 31, 2014 and December 31, 2013, the Company recovered $0.1 million and $0.9 million, respectively, on previously impaired asset-backed securities. The credit component of the impairment was determined to be the difference between amortized cost and the present value of the cash flows expected to be received, discounted at the original yield. The significant inputs used to project cash flows are estimated future prepayment rates, default rates and default loss severity.

Reinsurance Disclosures [Abstract]
Reinsurance	REINSURANCE
	Effective January 1, 2011, the Company began reinsuring any risk on any one life in excess of $500,000.  The Company's general policy prior to that date was to reinsure that portion of any risk in excess of $250,000 on the life of any one individual.  Total life insurance in force was $23.1 billion and $22.4 billion at December 31, 2014 and 2013, respectively.  Of these amounts, life insurance in force totaling $5.3 billion and $5.4 billion was ceded to reinsurance companies on a yearly renewable term basis, at December 31, 2014 and 2013, respectively.  In accordance with the reinsurance contracts, reinsurance receivables including amounts related to claims incurred but not reported and liabilities for future policy benefits totaled $7.4 million and $8.2 million at December 31, 2014 and 2013, respectively. Premiums and contract revenues were reduced by $19.0 million, $18.7 million and $19.8 million for reinsurance premiums ceded during 2014, 2013 and 2012, respectively. Benefit expenses were reduced by $6.4 million, $7.0 million and $8.2 million, for reinsurance recoveries during 2014, 2013 and 2012, respectively. A contingent liability exists with respect to reinsurance, as the Company remains liable if the reinsurance companies are unable to meet their obligations under the existing agreements.  The Company does not assume reinsurance.

	There were no deferred taxes attributable to enacted tax rate changes for the years ended December 31, 2014, 2013 and 2012.
	The Company expects its effective tax rate to be less than the statutory rate of 35% due to recurring permanent differences that reduce tax expense, principally tax exempt interest income and the dividend received deduction.
	The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2014 and 2013 are presented below.

	Net deferred tax liabilities	$	(31,675	)	(7,199	)
	There were no valuation allowances for deferred tax assets at December 31, 2014 and 2013.  In assessing deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.  The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.  Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and available tax planning strategies in making this assessment.  Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences.
	In accordance with GAAP, the Company assessed whether it had any significant uncertain tax positions related to open examination or other IRS issues and determined that there were none.  Accordingly, no reserve for uncertain tax positions was recorded.   Should a provision for any interest or penalties relative to unrecognized tax benefits be necessary, it is the Company's policy to accrue for such in its income tax accounts. There were no such accruals as of December 31, 2014 or 2013. The Company and its corporate subsidiaries file a consolidated U.S. Federal income tax return, which is subject to examination for all years after 2010.
	Allocation of the consolidated Federal income tax liability amongst the Company and its subsidiaries is based on separate return calculations pursuant to the "wait-and-see" method as described in sections 1.1552-1(a)(1) and 1.1502-33(d)(2) of the current Treasury Regulations.  Under this method, consolidated group members are not given current credit for net losses until future net taxable income is generated to realize such credits.

Pension and Other Postretirement Plans	PENSION AND OTHER POSTRETIREMENT PLANS
	(A)  Defined Benefit Pension Plans
	The Company sponsors a qualified defined benefit pension plan covering substantially all employees. 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, the Company’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 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 December 31 for each year.  A detail of plan disclosures is provided below.

The assumed long-term rate of return on plan assets is generally set at the rate expected to be earned based on the long-term investment policy of the plan and the various classes of invested funds, based on the input of the plan’s investment advisors and consulting actuary and the plan’s historic rate of return.  As of December 31, 2014, the plan’s average 10-year and inception-to-date returns were 6.14% and 7.28%, respectively.
In setting the annual discount rate assumption, the Pension Committee reviews the current 10 year and 30 year corporate bond yields, the current spread to treasuries and their relative change during the past twelve months. It also considers the present value of the projected benefit payment stream based on the Citigroup Pension Discount Curve. Based on the facts and circumstances currently existing, the Pension Committee elected to use the Citigroup Pension Discount Curve.
In setting the annual portfolio rate of return assumption, the Pension Committee considers the Plan’s actual long-term performance, the portfolio’s current allocation and individual investment holdings, the Committee’s and the investment manager’s expectations for future long term investment strategy and expected performance, and the advice of consultants knowledgeable about overall market expectations and benchmark rates of return used by comparable companies.
Plan Assets
As discussed in Note 14, Fair Values of Financial Instruments, the Company adopted GAAP guidance which defines fair value and establishes a framework for measuring fair value of financial assets.  Using this guidance, the Company has categorized its pension plan assets into a three level hierarchy, based on the priority of inputs to the valuation process.  The fair value hierarchy classifications are reviewed annually. Reclassification of certain financial assets and liabilities may result based on changes in the observability of valuation attributes.  The following table sets forth the Company’s pension plan assets within the fair value hierarchy as of December 31, 2014.

Investment securities.  Fair values for investments in debt and equity securities are based on quoted market prices, where available. For securities not actively traded, fair values are estimated using values obtained from various independent pricing services. In the cases where prices are unavailable from these sources, values are estimated by discounting expected future cash flows using a current market rate applicable to the yield, credit quality, and maturity of the investments.
Cash and cash equivalents.  The carrying amounts reported in the balance sheet for these instruments approximate their fair values.
The plan’s weighted-average asset allocations by asset category are as follows:
	December 31,
	2014		2013		2012
Asset Category:
Equity securities	64%		70%		60%
Debt securities	32%		29%		35%
Cash and cash equivalents	4%		1%		5%
Total	100%		100%		100%
The Company has established and maintains an investment policy statement for the assets held in the plan's trust.  The investment strategies are of a long-term nature and are designed to meet the following objectives:
Ÿ	ensure that funds are available to pay benefits as they become due
Ÿ	set forth an investment structure detailing permitted assets and expected allocation ranges among classes
Ÿ	ensure that plan assets are managed in accordance with ERISA
The Pension Plan is a highly diversified portfolio; the 96% of the pension assets not invested in cash or U.S. Government agencies are allocated among 225 different investments, with no single credit representing more than 2.1% of the fair value of the portfolio.  The investment policy statement sets forth the following acceptable ranges for each asset's class.
	Acceptable Range
Asset Category:
Equity securities	55-70%
Debt securities	30-40%
Cash and cash equivalents	0-15%
Deviations from these ranges are permitted if such deviations are consistent with the duty of prudence under ERISA.  Investments in natural resources, venture capital, precious metals, futures and options, real estate, and other vehicles that do not have readily available objective valuations are not permitted.  Short sales, use of margin or leverage, and investment in commodities and art objects are also prohibited.
The investment policy statement is reviewed annually to ensure that the objectives are met considering any changes in benefit plan design, market conditions, or other material considerations.
Contributions
The Company expects to contribute $0 to the plan during 2015 although additional amounts may be contributed.  The plan’s funding status is reviewed periodically throughout the year by the Company’s Pension Plan Committee.  The Company intends to contribute at least the minimum amounts necessary for tax compliance and to maintain an Adjusted Funding Target Attainment Percentage (AFTAP) of over 80% to meet the Pension Protection Act Plan’s threshold.
Estimated Future Benefit Payments
The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid (in thousands):
2015	$	1,339
2016	1,347

2019-2023	6,627
The Company also sponsors three nonqualified 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 the Company 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 this plan to allow an additional employee to participate and to change the benefit formula for the 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 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, the Company established a second nonqualified defined benefit plan for the benefit of the 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 nonqualified plan, while complying with the requirements of the Act.
Effective November 1, 2005, the Company established a third nonqualified defined benefit plan for the benefit of the 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 nonqualified plan as previously discussed, while complying with the requirements of the Act.

(B)  Defined Contribution Pension Plans
In addition to the defined benefit pension plans, the Company sponsors a qualified 401(k) plan for substantially all employees and a nonqualified deferred compensation plan primarily for senior officers.  The Company made annual contributions to the 401(k) plan in 2014, 2013 and 2012, of up to three percent of each employee's compensation based on the employee's personal level of salary deferrals to the plan.

For the years ended December 31, 2014, 2013 and 2012, Company contributions totaled $491,000, $410,000 and $323,000, respectively.
The nonqualified deferred compensation plan was established to allow eligible employees to defer the payment of a percentage of their compensation and to provide for additional Company contributions. Company contributions are subject to a vesting schedule based on the employee's years of service. For the years ended December 31, 2014, 2013 and 2012, Company contributions totaled $99,000, $140,000, and $66,000, respectively.
(C)  Postretirement Employment Plans Other Than Pension

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES
	(A)  Legal Proceedings
	In the normal course of business, the Company is involved or may become involved in various legal actions in which claims for alleged economic and punitive damages have been or may be asserted, some for substantial amounts. In recent years, carriers offering life insurance and annuity products have faced litigation, including class action lawsuits, alleging improper product design, improper sales practices, and similar claims. As discussed below, the Company has been a defendant over the past several years in such a class action lawsuit. 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.
	During 2014, the Company resolved a class action lawsuit pending since June 12, 2006, in the U.S. District Court for the Southern District of California. The case was titled In Re National Western Life Insurance Deferred Annuities Litigation. The complaint asserted claims for RICO violations, Financial Elder Abuse, Violation of Cal. Bus. & Prof. Code 17200, et seq, Violation of Cal. Bus. & Prof. Code 17500, et seq, Breach of Fiduciary Duty, Aiding and Abetting Breach of Fiduciary Duty, Fraudulent Concealment, Cal. Civ. Code 1710, et seq, Breach of the Duty of Good Faith and Fair Dealing, and Unjust Enrichment and Imposition of Constructive Trust. On July 12, 2010 the Court certified a nationwide class of policyholders under the RICO allegation and a California class under all of the remaining causes of action except breach of fiduciary duty. The parties entered into a Settlement and Release Agreement in August of 2013 ("Settlement") which was finally approved by the Court on February 11, 2014. On February 12, 2014, the Court issued a redacted final approval order granting the Motion for Final Approval of Class Action Settlement. The Settlement became final and non-appealable on April 12, 2014. The Settlement Agreement and Plaintiffs' Request for Attorneys' Fees and Costs were approved by the Court, and the Company paid the Court-approved amount of attorneys’ fees and costs in April 2014. The Company also made certain payments to surrendered and annuitized policyholders in June 2014. In addition, the Company agreed to provide bonuses on annuitization for active policyholders who choose a 10-year or a 20-year certain and life settlement option. The Company had held reserves of $6.5 million for the matter at December 31, 2013 which approximated the ultimate settlement amounts described above.
	In addition to the class action lawsuit described above, the Company was the named defendant in the case of Sheila Newman vs. National Western Life Insurance Company, which alleged mishandling of policyholder funds by an agent.  On February 3, 2010, the 415th Judicial District Court of Parker County in Weatherford, Texas, entered a Final Judgment against the Company of approximately $208,000 including actual damages of $113,000 and amounts for attorney's fees, and prejudgment interest on the actual damages.  In addition, the Final Judgment included $150 million for exemplary damages. The Company vigorously defended this case and appealed the Final Judgment to the Court of Appeals Second District of Texas in Fort Worth. The Court of Appeals on August 11, 2011, reversed the trial court judgment in its entirety and rendered a take nothing verdict in favor of National Western. Plaintiffs (Appellees) filed a motion for a rehearing which the Court ruled on October 13, 2011, that the trial court's judgment was still reversed and judgment was still entered that Newman take nothing, all in favor of National Western. The Plaintiffs (Appellees) filed a Motion for Reconsideration En Banc which the Court of Appeals denied on October 27, 2011. The Plaintiffs (Appellees) then filed a Motion for Rehearing of the Court's amended decision, which the Court of Appeals denied on December 22, 2011. On March 21, 2012, Plaintiffs (Appellees) filed a petition for review with the Texas Supreme Court and the Company filed its response on April 20, 2012. The Supreme Court asked the parties for briefs on the issues before deciding on whether to hear the case and both parties submitted their briefs. On February 14, 2013, the Supreme Court denied the Plaintiffs petition for review. On April 3, 2013, Plaintiff filed a Motion for Rehearing. The Supreme Court denied Plaintiff's Motion for Rehearing on June 7, 2013 thus ending the matter.
	On October 26, 2011 the Brazilian Superintendence of Private Insurance (“SUSEP”) attempted to serve the Company with a subpoena regarding an administrative proceeding initiated by SUSEP in which it alleged that the Company was operating as an insurance company in Brazil without due authorization.  The Company had been informed that SUSEP was attempting to impose a penal fine of approximately $6.0 billion on the Company.  SUSEP unsuccessfully attempted to serve the Company with notice regarding this matter.  The Company does not transact business in Brazil and has no officers, employees, property, or assets in Brazil.  The Company 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.  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.
	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 Company has recently become aware that the Brazilian authorities have commenced an investigation into possible violations of Brazilian criminal law in connection with the issuance of the Company's 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. Because the Company has only recently become aware of this investigation, 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. The Company plans to cooperate 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 consolidated balance sheet.
	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 $7.0 million of commitments to extend credit relating to loans at December 31, 2014. The Company evaluates each customer's creditworthiness on a case-by-case basis.
	(C)  Guaranty Association Assessments
	The Company is subject to state guaranty association assessments in all states in which it is licensed to do business.  These associations generally guarantee certain levels of benefits payable to resident policyholders of insolvent insurance companies. Many states allow premium tax credits for all or a portion of such assessments, thereby allowing potential recovery of these payments over a period of years.  However, several states do not allow such credits.
	The Company estimates its liabilities for guaranty association assessments by using the latest information available from the National Organization of Life and Health Insurance Guaranty Associations.  The Company monitors and revises its estimates for assessments as additional information becomes available which could result in changes to the estimated liabilities.  As of December 31, 2014 and 2013, liabilities for guaranty association assessments totaled $0.3 million and $1.0 million, respectively. Other operating expenses related to state guaranty association assessments were minimal for the years ended December 31, 2014, and 2013. Guaranty association assessment expense for the year ended December 31, 2012 was approximately $1.9 million as a result of an assessment from the State of California Life and Health Insurance Guarantee Association for the final costs associated with the Executive Life insolvency.
	(D)  Leases
	The Company leases various computers and other office related equipment under operating leases. Rental expenses for these leases were $0.1 million, $0.4 million and $0.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.  The Company's future annual lease obligations as of December 31, 2014 are in the table below (in thousands).
	2015	$	214
	2016 and thereafter	880
	Total	$	1,094
	(E)  Compensation Plan
	Effective January 1, 2006, the Company implemented a nonqualified deferred compensation plan to provide incentive bonuses to eligible agents.  Agents qualify for participation by meeting certain sales goals each year.  Company contributions are subject to a vesting schedule based on the agents’ years of qualification in the plan.  The Company expects that it will terminate the plan in 2015, pay out approximately $1.8 million of vested balances as of December 31, 2014, and recover nonvested amounts of approximately $1.2 million.

	The Company 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 2015 is $118.2 million.
	On August 22, 2014, the Board of Directors of the Company declared a cash dividend to stockholders on record as of October 31, 2014 and payable December 4, 2014.  The dividends approved were $0.36 per common share to Class A stockholders and $0.18 per common share to Class B stockholders.  A dividend in the same amounts per share on Class A and Class B shares was declared in August and paid in December of 2013.
	(C)  Regulatory Capital Requirements
	The Colorado Division of Insurance imposes minimum risk-based capital requirements on insurance companies that were developed by the National Association of Insurance Commissioners ("NAIC").  The formulas for determining the amount of risk-based capital ("RBC") specify various weighting factors that are applied to statutory financial balances or various levels of activity based on the perceived degree of risk.  Regulatory compliance is determined by a ratio of the Company's regulatory total adjusted capital to its authorized control level RBC, as defined by the NAIC.  Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action.  The Company's current authorized control level RBC of $72.4 million is significantly below its total adjusted capital of $1.3 billion.
	(D)  Share-Based Payments
	The Company has a stock and incentive plan ("1995 Plan") which provides 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; and (4) performance awards. The Company has issued only nonqualified stock options under the 1995 Plan. 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 or other awards were allowed to be granted, could not exceed 300,000. All shares under the 1995 Plan have been issued. 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, $1.00 par value, common stock shares eligible for issue not to exceed 300,000.
	All of the employees of the Company and its subsidiaries are eligible to participate in the two Plans. 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. The directors’ grants vest 20% annually following one full year of service to the Company from the date of grant. The employees’ grants vest 20% annually following three full years of service to the Company from the date of grant. All grants issued expire after ten years.
	In 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 Plan, however the program necessitated a change in accounting from the equity classification to the liability classification. In 2008, the Company implemented another limited stock buy-back program, substantially similar to the 2006 program, for shares issued under the 2008 Plan.
	The Company uses the current fair value method to measure compensation cost. As of December 31, 2014, the liability balance was $9.3 million versus $5.9 million as of December 31, 2013. A summary of shares available for grant and stock option activity is detailed below.

	In estimating the fair value of the options/SARs outstanding at December 31, the Company employed the Black-Scholes option pricing model with assumptions as detailed below.
		December 31, 2014		December 31, 2013
	Expected term of options	3.3 to 9.0 years		0 to 10 years
	Expected volatility:
	Range	19.67% to 37.75%		21.03% to 42.71%

	Expected dividend yield	0.13	%	0.16	%
	Risk-free rate:
	Range	0.13% to 1.62%		0.12% to 3.93%
	Weighted-average	0.56	%	2.1	%
	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.
	The pre-tax compensation expense/(benefit) recognized in the financial statements related to the two Plans was $4.4 million, $5.7 million and $1.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. The related tax (benefit)/expense recognized was $(1.5) million, $(2.0) million and $(0.4) million for the years ended December 31, 2014, 2013 and 2012, respectively.
	For the years ended December 31, 2014, 2013 and 2012, the total pre-tax compensation expense related to nonvested options not yet recognized was $2.3 million, $3.7 million and $1.7 million, respectively.  This amount is expected to be recognized over a weighted-average period of 2.3 years.  The Company recognizes compensation cost over the graded vesting periods.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE
	Earnings per share amounts for the Company are presented using two different computations.  Basic earnings per share excludes dilutive effects of certain securities or contracts, such as stock options, and is computed by dividing 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 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. Stock options not included in the weighted-average number of diluted shares, because such shares would have been anti-dilutive, were immaterial.  U.S. GAAP requires a two-class presentation for the Company’s two classes of common stock (Note 6, Transactions with Controlling Stockholder).  Accordingly, the earnings per share for both Class A and Class B are presented.  The following table sets forth the computations of basic and diluted earnings per share.

Equity [Abstract]
Comprehensive Income	COMPREHENSIVE INCOME
	GAAP guidance requires that all items recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements.  This guidance requires that an enterprise (a) classify items of other comprehensive income by their nature in a financial statement and (b) display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the equity section of a statement of financial position.
	This guidance affects the Company's reporting presentation of certain items such as foreign currency translation adjustments, unrealized gains and losses on investment securities, and pension liabilities.  These items are reflected as components of other comprehensive income (loss), as reported in the accompanying consolidated financial statements.  Components of other comprehensive income (loss) for 2014, 2013 and 2012 and the related tax effect are detailed below.

Segment Reporting [Abstract]
Segment and Other Operating Information	SEGMENT AND OTHER OPERATING INFORMATION
	(A)  Operating Segment Information
	The Company defines its reportable operating segments as domestic life insurance, international life insurance, and annuities.  The Company's segments are organized based on product types and geographic marketing areas.  In addition, the Company regularly evaluates operating performance using non-GAAP financial measures which exclude or segregate realized investment gains and losses from operating revenues and earnings.  The Company believes that the presentation of these non-GAAP financial measures enhances the understanding of the Company's results of operations by highlighting the results from ongoing operations and the underlying profitability factors of the Company's business.  The Company excludes or segregates realized investment gains and losses because such items are often the result of events which may or may not be at the Company's discretion and the fluctuating effects of these items could distort trends in the underlying profitability of the Company's business.

Fair Value Disclosures [Abstract]
Fair Values of Financial Instruments	FAIR VALUES OF FINANCIAL INSTRUMENTS
	Effective January 1, 2008, the Company adopted FASB 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 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 table sets forth the Company’s assets and liabilities that are measured at fair value on a recurring basis as of the date indicated.

During the year ended December 31, 2013, the Company transferred its index option holdings from level 2 to level 3. Although these securities contain significant inputs which are directly or indirectly observable, the pricing of these derivative instruments involves judgment regarding assumptions market participants would use. Consequently, the Company determined that these assets did not meet the criteria for Level 2 classification. The Company correspondingly transferred the policyholder account balance liability with the associated embedded derivatives from level 2 to level 3. The following tables show the quantitative information about the Company's level 3 assets and liabilities.

Realized gains (losses) on Level 3 assets are reported in the consolidated statements of earnings as net investment gains (losses) with liabilities reported as expenses. Unrealized gains (losses) on debt and equity securities are reported as other comprehensive income (loss) within stockholders’ equity.
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.
GAAP defines fair value, establishes a framework for measuring fair value and requires additional disclosures about fair value measurements.  Fair value is based on an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The objective of a fair value measurement is to determine that price for each financial instrument at each measurement date. GAAP also establishes a hierarchal disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a variety of factors including the type of instrument and the characteristics of instruments. Financial instruments with readily available active quoted prices or those for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measures.
The following methods and assumptions were used in estimating the fair value of financial instruments and liabilities during the periods presented in the consolidated financial statements.
Fixed maturity securities.  Fair values for investments in debt securities available for sale are based on quoted market prices, where available. For securities not actively traded, fair values are estimated using values obtained from various independent pricing services with any adjustments based upon observable data. In the cases where prices are unavailable for these sources, values are estimated by discounting expected future cash flows using a current market rate applicable to the yield, credit quality, and maturity of the investments.
Equity securities.  Fair values for equity securities are based upon quoted market prices, where available. For equity securities that are not actively traded, estimated values are based on values of comparable issues or audited financial statements of the issuer.
Cash and cash equivalents.  The carrying amounts reported in the balance sheet for these instruments approximate their fair values due to the relatively short time between the purchase of the instrument and its expected repayment or maturity.
Mortgage and other loans. The fair values of performing mortgage and other loans are estimated by discounting scheduled cash flows through the scheduled maturities of the loans, using interest rates currently being offered for similar loans to borrowers with similar credit ratings. Fair values for significant nonperforming loans are based on recent internal or external appraisals. If appraisals are not available, estimated cash flows are discounted using a rate commensurate with the risk associated with the estimated cash flows.  Assumptions regarding credit risk, cash flows, and discount rates are judgmentally determined using available market information and specific borrower information.
Policy Loans.  Policy loans with fixed interest rates are classified within Level 3. The estimated fair values for these loans are determined using a discounted cash flow model applied to groups of similar policy loans determined by the nature of the underlying insurance liabilities. Cash flow estimates are developed by applying a weighted-average interest rate to the outstanding principal balance of the respective group of policy loans and an estimated average maturity. These cash flows are discounted using current risk-free interest rates with no adjustment for borrower credit risk as these loans are collateralized by the cash surrender value of the underlying insurance policy.
Derivatives. Fair values for index (call) options are based on counterparty market prices.  The counterparties use market standard valuation methodologies incorporating market inputs for volatility and risk free interest rates in arriving at a fair value for each option contract. Prices are monitored for reasonableness by the Company using analytical tools. There are no performance obligations related to the call options purchased to hedge the Company’s fixed-index life and annuity policy liabilities.
Life interest in Libbie Shearn Moody Trust.  The fair value of the life interest was estimated based on assumptions as to future distributions from the Trust over the life expectancy of Mr. Robert L. Moody, Chairman of the Board and Chief Executive Officer. These estimated cash flows were discounted at a rate consistent with uncertainties relating to the amount and timing of future cash distributions subject to the maximum amount to be received from insurance proceeds in the event of Mr. Moody's death. The carrying value or cost basis of the life interest asset was amortized ratably over the expected life of Mr. Moody.
Annuity and supplemental contracts.  Fair values for the Company's insurance contracts other than annuity contracts are not required to be disclosed. This includes the Company's traditional and universal life products. Fair values for immediate annuities without mortality features are based on the discounted future estimated cash flows using current market interest rates for similar maturities.  Fair values for deferred annuities, including fixed-indexed annuities, are determined using estimated projected future cash flows discounted at the rate that would be required to transfer the liability in an orderly transaction.  The fair values of liabilities under all insurance contracts are taken into consideration in the Company's overall management of interest rate risk, which minimizes exposure to changing interest rates through the matching of investment maturities with amounts due under insurance and annuity contracts.
The Company utilizes independent third-party pricing services to determine the majority of its fair values of investment securities. The independent pricing services provide quoted market prices when available or otherwise incorporate a variety of observable market data in their valuation techniques including reported trading prices, broker-dealer quotes, bids and offers, benchmark securities, benchmark yields, credit ratings, and other reference data. The Company reviews prices received from service providers for unusual fluctuations to ensure that the prices represent a reasonable estimate of fair value but generally accepts the price identified from the primary pricing service.
When quoted market prices in active markets are unavailable, the Company determines fair values using various valuation techniques and models based on a range of observable market inputs including pricing models, quoted market price of publicly traded securities with similar duration and yield, time value, yield curve, prepayment speeds, default rates and discounted cash flow.  In most cases, these estimates are determined based on independent third party valuation information, and the amounts are disclosed in Level 2 of the fair value hierarchy.  Generally, the Company obtains a single price or quote per instrument from independent third parties to assist in establishing the fair value of these investments.
Fair value measurements for investment securities where there exists limited or no observable data are calculated using the Company’s own estimates based on current interest rates, credit spreads, liquidity premium or discount, the economic and competitive environment, unique characteristics of the security and other pertinent factors. These estimates are derived a number of ways including, but not limited to, pricing provided by brokers where the price indicates reliability as to value, fair values of comparable securities incorporating a spread adjustment (for maturity differences, credit quality, liquidity, collateralization), discounted cash flow models and margin spreads, bond yield curves, and observable market prices and exchange transaction information not provided by external pricing services. The resulting prices may not be realized in an actual sale or immediate settlement and there may be inherent weaknesses in any calculation technique. In addition, changes in underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.

Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instruments.  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 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 that are 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 consolidated financial statements. The changes in the values of the index options and the changes in the policyholder liabilities are both reflected in the consolidated statements of earnings. Any changes relative to the embedded derivatives associated with policy contracts are reflected in contract interest in the 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 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.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation. The accompanying consolidated financial statements include the accounts of National Western Life Insurance Company and its wholly owned subsidiaries (“National Western” or "Company"). The wholly owned subsidiaries consist of The Westcap Corporation, Regent Care San Marcos Holdings, LLC, NWL Investments, Inc., NWL Services, Inc., NWLSM, Inc., and NWL Financial, Inc.  All significant intercorporate transactions and accounts have been eliminated in consolidation.
Basis of Presentation	Basis of Presentation.  The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") which require 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 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) commitments and contingencies, (5) valuation allowances for deferred tax assets, (6) other-than-temporary impairment losses on debt securities, 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 years ended December 31, 2014, 2013 and 2012.

	The Company also files financial statements with insurance regulatory authorities which are prepared on the basis of statutory accounting practices prescribed or permitted by the Colorado Division of Insurance which are significantly different from consolidated financial statements prepared in accordance with GAAP.  These differences are described in detail in the statutory information section of this note.
	Certain amounts in the prior year consolidated financial statements have been reclassified to conform to the current year presentation.
Investments	Investments. Investments in debt securities the Company purchases with the intent to hold to maturity are classified as securities held to maturity. The Company has the ability to hold the securities until maturity, as it would be unlikely that forced sales of securities would be required, prior to maturity, to cover payments of liabilities. As a result, securities held to maturity are carried at amortized cost less declines in fair value that are deemed other-than-temporary.
	Investments in debt and equity securities that are not classified as securities held to maturity are reported as securities available for sale. Securities available for sale are reported in the accompanying consolidated financial statements at fair value.  Valuation changes resulting from changes in the fair value of the securities are reflected as a component of stockholders' equity in accumulated other comprehensive income (loss).  These unrealized gains or losses in stockholders' equity are reported net of taxes and adjustments to deferred policy acquisition costs.
	Transfers of securities between categories are recorded at fair value at the date of transfer.
	Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method.  For mortgage-backed and asset-backed securities, the effective interest method is used based on anticipated prepayments and the estimated economic life of the securities.  When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments.  The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied at the time of acquisition.  This adjustment is reflected in net investment income.
	Quarterly the Company reviews its investment portfolio for market value changes to identify changes caused by issuer credit deterioration, changes in market interest rates and changes in economic conditions.  If this review indicates a decline in fair value that is other-than-temporary, the Company’s carrying amount in the investment is reduced to its estimated fair value.  In accordance with GAAP guidance the estimated credit versus non-credit components are bifurcated.  The credit component is taken through earnings.  The non-credit component is reclassified as unrealized loss in other comprehensive income.  The Company would not recognize impairment of securities due to changing of interest rates or market dislocations unless the Company had the intent to sell the securities prior to recovery or maturity.
	The Company considers a number of factors in determining whether the impairment is other-than-temporary.  These include, but are not limited to:  1) actions taken by rating agencies, 2) default by the issuer, 3) the significance of the decline in fair value, 4) the intent and ability to hold the investment until recovery, 5) the time period during which the decline has occurred, 6) an economic analysis of the issuer’s industry, and 7) the financial strength, liquidity, and recoverability of the issuer.  Management performs a security-by-security review each quarter in evaluating the need for any other-than-temporary impairments.  Although no set formula is used in this process, the investment performance, collateral position, and continued viability of the issuer are significant measures considered.
	Realized gains and losses for securities available for sale and securities held to maturity are included in earnings and are derived using the specific identification method for determining the cost of securities sold or called.  Decline in the fair value below cost that is deemed other-than-temporary is bifurcated in credit and non-credit declines.  The noncredit related declines are reclassified as unrealized losses in accumulated other comprehensive income (loss).  Credit losses are recorded in earnings and result in the establishment of a new cost basis for the security.  The new discount or reduced premium amount is amortized over the remaining life of the impaired debt security prospectively based on the amount and timing of future estimated cash flows.
	Mortgage loans and other long-term investments are stated at cost, less unamortized discounts, deferred fees, and allowances for possible losses. Policy loans are stated at their aggregate unpaid balances. Real estate is stated at the lower of cost or fair value less estimated costs to sell.
	Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected.  The Company has identified these loans through its normal loan review procedures.  Impaired loans include: 1) nonaccrual loans, 2) loans which are 90 days or more past due, unless they are well secured and are in the process of collection, and 3) other loans which management believes are impaired.  Impaired loans are measured based on: 1) the present value of expected future cash flows discounted at the loan's effective interest rate, 2) the loan's observable market price, or 3) the fair value of the collateral if the loan is collateral dependent.  Substantially all of the Company's impaired loans are measured at the fair value of the collateral.  In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent.
	While the Company closely manages its investment portfolio, future changes in issuer facts and circumstances can result in impairments beyond those currently identified.
Cash and Short-term Investment	Cash and Cash Equivalents. For purposes of the consolidated statements of cash flows, the Company considers all short-term investments with a maturity at the date of purchase of three months or less to be cash equivalents.
Derivatives	Derivatives.   Fixed-index products combine features associated with traditional fixed annuities and universal life contracts, with the option to have interest rates linked in part to an underlying equity index.  The equity return component of such policy contracts is identified separately and accounted for in future policy benefits as embedded derivatives on the consolidated balance sheet.  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.  The host contracts are recorded as discounted debt instruments that are 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 index annuity and life products.  The amounts which may be credited to policyholders are linked, in part, to the returns of the underlying index. The index options act as hedges to match closely the returns on the underlying index.  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 is paid to the Company based on the underlying index performance and terms of the contract.  As a result, amounts credited to policyholders' account balances are substantially offset by changes in the value of the options.
	The Company does not elect hedge accounting relative to derivative instruments. The derivatives are reported at fair value in the accompanying consolidated financial statements.  Changes in the values of the index options and changes in the policyholder liabilities are both reflected in the statement 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 statement of earnings.  Any changes relative to the embedded derivatives associated with policy contracts are reflected in contract interest in the consolidated statement of earnings.
	Although there is credit risk in the event of nonperformance by counterparties to the index options, the Company does not expect any 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.
Insurance Revenue and Expenses	Insurance Revenues and Expenses. Premiums on traditional life insurance products are recognized as revenues as they become due from policyholders. Benefits and expenses are matched with premiums in arriving at profits by providing for policy benefits over the lives of the policies and by amortizing acquisition costs over the premium-paying periods of the policies. For universal life and annuity contracts, revenues consist of policy charges for the cost of insurance, policy administration, and surrender charges assessed during the period.  Expenses for these policies include interest credited to policy account balances, benefit claims incurred in excess of policy account balances and amortization of deferred policy acquisition costs and deferred sales inducements.
	Under GAAP, commissions, sales inducements, and certain expenses related to policy issuance and underwriting, all of which vary with and are related to the production of new business, are deferred. For traditional products, these costs are amortized over the premium-paying period of the related policies in proportion to the ratio of the premium earned to the total premium revenue anticipated, using the same assumptions as to interest, mortality, and withdrawals as were used in calculating the liability for future policy benefits. For universal life and annuity contracts, these costs are amortized in relation to the present value of expected gross profits on these policies.  The Company evaluates the recoverability of deferred policy acquisition and sales inducement costs on a quarterly basis.  In this evaluation, the Company considers estimated future gross profits or future premiums, as applicable for the type of contract.  The Company also considers expected mortality, interest earned and credited rates, persistency, and expenses.
Deferred Federal Income Tax	Deferred Federal Income Taxes. Federal income taxes are accounted for under the asset and liability method.  Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  A valuation allowance for deferred tax assets is provided if all or some portion of the deferred tax asset may not be realized.  An increase or decrease in a valuation allowance that results from a change in circumstances that affects the realizability of the related deferred tax asset is included in income in the period the change occurs.
Depreciation of Property, Equipment, and Leasehold Improvements	Depreciation of Property, Equipment, and Leasehold Improvements. Depreciation is based on the estimated useful lives of the assets and is calculated on the straight-line and accelerated methods.  Leasehold improvements are amortized over the lesser of the economic useful life of the improvement or the term of the lease.
Stock Compensation	Stock Compensation. The Company accounts for its share-based compensation for GAAP reporting using liability accounting, and measures compensation cost using the fair value method at each reporting date.  For stock options, fair value is determined using an option pricing model that takes into account various information and assumptions including the Company's stock price, volatility, option price, vesting dates, exercise dates and projected option lapses.  Under the intrinsic value based method, compensation cost is the excess, if any, of the quoted market price of the stock at grant date or other measurement date over the amount an employee must pay to acquire the stock.
