Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of The National Security Group, Inc. (the Company) and its wholly-owned subsidiaries: National Security Insurance Company (NSIC), National Security Fire and Casualty Company (NSFC) and NATSCO, Inc. (NATSCO). NSFC includes a wholly-owned subsidiary, Omega One Insurance Company (Omega). The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements have been included. All significant intercompany transactions and accounts have been eliminated. The financial information presented herein should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, which includes information and disclosures not presented herein. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Among the more significant estimates included in these consolidated financial statements are reserves for future life insurance policy benefits, liabilities for losses and loss adjustment expenses, reinsurance recoverable associated with loss and loss adjustment expense liabilities, deferred policy acquisition costs, deferred income tax assets and liabilities, assessments of other-than-temporary impairments on investments and accruals for contingencies. Actual results could differ from these estimates. Earnings Per Share Earnings per share of common stock is based on the weighted average number of shares outstanding during each year. The adjusted weighted average shares outstanding were 2,522,312 at March 31, 2018 and 2,517,339 at March 31, 2017. The Company did not have any dilutive securities as of March 31, 2018 and 2017. Reclassifications Certain 2017 amounts have been reclassified from the prior year consolidated financial statements to conform to the 2018 presentation. Concentration of Credit Risk The Company maintains cash balances which are generally held in non-interest bearing demand deposit accounts subject to FDIC insured limits of $250,000 per entity. At March 31, 2018 , the net amount exceeding FDIC insured limits was $ 3,654,000 at three financial institutions. The Company has not experienced any losses in such accounts. Management of the Company reviews financial information of financial institutions on a quarterly basis and believes the Company is not exposed to any significant credit risk on cash and cash equivalents. Policy receivables are reported at unpaid balances. Policy receivables are generally offset by associated unearned premium liabilities and are not subject to significant credit risk. Receivables from agents, less provision for credit losses, are composed of balances due from independent agents. At March 31, 2018 , the single largest balance due from one agent totaled $729,000 . Reinsurance contracts do not relieve the Company of its obligations to policyholders. A failure of a reinsurer to meet its obligation could result in losses to the insurance subsidiaries. Allowances for losses on reinsurance recoverables are established if amounts are believed to be uncollectible. At March 31, 2018 and December 31, 2017, no amounts were deemed uncollectible. The Company, at least annually, evaluates the financial condition of all reinsurers and evaluates any potential concentrations of credit risk. At March 31, 2018 , management does not believe the Company is exposed to any significant credit risk related to its reinsurance program. Accounting Changes Not Yet Adopted Recognition and Measurement of Financial Assets and Financial Liabilities In February 2018, the Financial Accounting Standards Board (FASB) issued guidance to address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years beginning after June 15, 2018. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Leases In February 2016, the FASB issued guidance that requires lessees (for capital and operating leases) to recognize the lease liability and right-of-use asset at the commencement date of the lease. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Contingent Put and Call Options in Debt Instruments In March 2016, the FASB issued guidance that clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Financial Instruments - Credit Losses In June 2016, the FASB issued guidance that replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Receivables - Nonrefundable Fees and Other Costs In March 2017, the FASB issued guidance that shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. The guidance is effective for fiscal years beginning after December 15, 2018 and interim reporting periods within those fiscal years. The Company does not expect the adoption of this new guidance to have a significant impact on our financial position, results of operations or cash flows. Derivatives and Hedging In August 2017, the FASB issued guidance that amends and simplifies hedge accounting guidance in order to enable entities to better portray the economic results of their risk management activities. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted. The Company is currently evaluating the impact of the standard on its consolidated financial statements and related disclosures. Recently Adopted Accounting Standards Income Statement - Reporting Comprehensive Income In February 2018, the Financial Accounting Standards Board (FASB) issued guidance that allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The guidance eliminates the stranded tax effects resulting from the Tax Cuts and Jobs Act and improves the usefulness of information reported to financial statement users. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted. The Company adopted this guidance as of December 31, 2017. The adoption of this guidance resulted in a $435,000 reclassification to accumulated other comprehensive income from retained earnings related to stranded tax effects resulting from the Tax Cuts and Jobs Act. Revenue from Contracts with Customers In May 2014, FASB issued guidance on a comprehensive new revenue recognition standard. This standard will not impact accounting for insurance contracts, leases, financial instruments and guarantees. For those contracts that are impacted by the new guidance, the guidance will require an entity to recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to, in exchange for those goods or services. The guidance requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued a deferral of the effective date by one year. This guidance is effective retrospectively for fiscal years beginning after December 15, 2017 and interim periods within those years. Early adoption of this standard is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Insurance contracts are specifically scoped out of this new guidance. The Company does not have policy fees or any material services that may be subject to the new revenue recognition guidance. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have an impact on its condensed consolidated financial statements. Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued guidance that requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The guidance requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset. The guidance eliminates the requirement for public companies to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. This guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance resulted in a $2,107,000 reclassification to retained earnings from accumulated other comprehensive income related to accumulated unrealized gains on equity securities as well as recognition of a $162,000 loss, net of tax, related to the change in value of equity securities. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued guidance that clarifies how certain cash receipts and cash payments shall be presented and classified in the statement of cash flows. This guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The guidance is effective for annual and interim reporting periods beginning after December 15, 2017. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows. Compensation - Stock Compensation In May 2017, the FASB issued guidance to provide clarity and reduce diversity in practice as well as cost and complexity when there is a change in the terms or conditions of a share-based payment award. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows.

The Company conducts periodic reviews to identify and evaluate securities in an unrealized loss position in order to identify other-than-temporary impairments. For securities in an unrealized loss position, the Company assesses whether the Company has the intent to sell the security or more-likely-than-not will be required to sell the security before the anticipated recovery. If either of these conditions is met, the Company is required to recognize an other-than-temporary impairment with the entire unrealized loss reported in earnings. For securities in an unrealized loss position that do not meet these conditions, the Company assesses whether the impairment of a security is other-than-temporary. If the impairment is determined to be other-than-temporary, the Company is required to separate the other-than-temporary impairments into two components: the amount representing the credit loss and the amount related to all other factors. The credit loss is the portion of the amortized book value in excess of the net present value of the projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. The credit loss component of other-than-temporary impairments is reported in earnings, whereas the amount relating to factors other than credit losses are recorded in other comprehensive income, net of taxes. Management has evaluated each security in a significant unrealized loss position in both the debt and equity investment portfolios. The Company has no material exposure to sub-prime mortgage loans and approximately 5.94% of the fixed income investment portfolio is rated below investment grade. In evaluating whether or not the equity loss positions were other-than-temporary impairments, Management evaluated financial information on each company and where available, reviewed analyst reports from at least two independent sources. Based on a review of the available financial information, the prospect for future earnings of each company and consideration of the Company’s intent and ability to hold the securities until market values recovered, it was determined that the securities in an accumulated loss position in the portfolio were temporary impairments. For the three months ended March 31, 2018 and year ended December 31, 2017, the Company realized no other-than-temporary impairments. At March 31, 2018, the single largest loss not realized as an impairment was in the bond portfolio and totaled $88,000 . The second largest loss position was in the bond portfolio and totaled $87,000 . The third largest loss position was in the bond portfolio and totaled $81,000 . At December 31, 2017, the single largest loss not realized as an impairment was in the bond portfolio and totaled $75,000 . The second largest loss position was in the bond portfolio and totaled $60,000 . The third largest loss position was in the bond portfolio and totaled $53,000 .

Fair Value of Financial Assets

Fair Value of Financial Assets and Financial Liabilities	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Financial Liabilities	FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES Our available-for-sale securities consists of fixed maturity and equity securities which are recorded at fair value in the accompanying consolidated balance sheets. The change in the fair value of these investments, unless deemed to be other-than-temporarily impaired, is recorded as a component of other comprehensive income. We are permitted to elect to measure financial instruments and certain other items at fair value, with the change in fair value recorded in earnings. We elected not to measure any eligible items using the fair value option. Accounting standards define fair value as the price that would be received to sell an asset or would be paid to transfer a liability in an orderly transaction between market participants at the measurement date, and establishes a framework to make the measurement of fair value more consistent and comparable. In determining fair value, we primarily use prices and other relevant information generated by market transactions involving identical or comparable assets. The Company categorizes assets and liabilities carried at their fair value based upon a fair value hierarchy: Level 1 – Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 1 assets and liabilities consist of money market fund deposits and certain of our marketable debt and equity instruments, including equity instruments offsetting deferred compensation, that are traded in an active market with sufficient volume and frequency of transactions. Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include certain of our marketable debt and equity instruments with quoted market prices that are traded in less active markets or priced using a quoted market price for similar instruments. Level 2 assets also include marketable equity instruments with security-specific restrictions that would transfer to the buyer, marketable debt instruments priced using indicator prices which represent non-binding market consensus prices that can be corroborated by observable market quotes, as well as derivative contracts and debt instruments priced using inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Marketable debt instruments in this category generally include commercial paper, bank time deposits, repurchase agreements for fixed-income instruments, and a majority of floating-rate notes, corporate bonds, and municipal bonds. Level 3 - Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. Level 3 assets and liabilities include marketable debt instruments, non-marketable equity investments, derivative contracts, and company issued debt with values are determined using inputs that are both unobservable and significant to the values of the instruments being measured. Level 3 assets also include marketable debt instruments that are priced using indicator prices that we were unable to corroborate with observable market quotes. Marketable debt instruments in this category generally include asset-backed securities and certain floating-rate notes, corporate bonds, and municipal bonds. Assets/Liabilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2018 are summarized in the following table by the type of inputs applicable to the fair value measurements (in thousands): Fair Value Measurements at Reporting Date Using Description Total Level 1 Level 2 Level 3 Financial Assets Fixed maturities available-for-sale Corporate debt securities $ 38,840 $ — $ 38,840 $ — Mortgage backed securities 11,624 — 11,624 — Private label asset backed securities 12,928 — 12,928 — Obligations of states and political subdivisions 13,597 — 13,597 — U.S. Treasury securities and obligations of U.S. Government corporations and agencies 18,836 18,836 — — Trading securities 107 107 — — Equity securities 4,303 3,201 — 1,102 Total Financial Assets $ 100,235 $ 22,144 $ 76,989 $ 1,102 Financial Liabilities Interest rate swap $ (441 ) $ — $ — $ (441 ) Total Financial Liabilities $ (441 ) $ — $ — $ (441 ) The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below. Fixed maturities available-for-sale — The fair values of the Company’s public fixed maturity securities are generally based on prices obtained from independent pricing services. Consistent with the fair value hierarchy described above, securities with validated quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. Trading securities — Trading securities consist primarily of mutual funds whose fair values are determined consistent with similar instruments described above under “Fixed Maturities” and below under “Equity Securities.” Equity securities — Equity securities consist principally of investments in common and preferred stock of publicly traded companies and privately traded securities. The fair values of our publicly traded equity securities are based on quoted market prices in active markets for identical assets and are classified within Level 1 in the fair value hierarchy. Estimated fair values for our privately traded equity securities require a substantial level of judgment. Privately traded equity securities are classified within Level 3. Interest rate swaps — Interest rate swaps are recorded at fair value either as assets, within other assets or as liabilities, within other liabilities. The fair values of our interest rate swaps are provided by a third-party broker and are classified within Level 3. As of March 31, 2018 , Level 3 fair value measurements of assets include $1,102,000 of equity securities in a local community bank whose value is based on an evaluation of the financial statements of the entity. The Company does not develop the unobservable inputs used in measuring fair value. As of March 31, 2018 , Level 3 fair value measurements of liabilities include $441,000 net fair value of various interest rate swap agreements whose value is based on analysis provided by a third party that utilizes financial modeling tools and assumptions on interest and other factors. The Company does not develop the unobservable inputs used in measuring fair value. Additional information regarding the interest rate swap agreements is provided in Note 7. The table below presents a reconciliation for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2018 (in thousands): For the three months ended March 31, 2018 Equity Securities Interest Rate Swap Beginning balance $ 1,073 $ (608 ) Total gains or losses (realized and unrealized): Included in earnings 29 — Included in other comprehensive income — 167 Purchases: — — Sales: — — Issuances: — — Settlements: — — Transfers in/(out) of Level 3 — — Ending balance $ 1,102 $ (441 ) The amount of total gains or losses for the period included in earnings attributable to the change in unrealized gains or losses relating to assets and liabilities still held as of March 31, 2018: $ — $ — For the three months ended ended March 31, 2018 , there were no assets or liabilities measured at fair values on a nonrecurring basis. Financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2017 are summarized in the following table by the type of inputs applicable to the fair value measurements (in thousands): Fair Value Measurements at Reporting Date Using Description Total Level 1 Level 2 Level 3 Financial Assets Fixed maturities available-for-sale Corporate debt securities $ 39,909 $ — $ 39,909 $ — Mortgage backed securities 12,795 — 12,795 — Private label asset backed securities 10,510 — 10,510 — Obligations of states and political subdivisions 14,093 — 14,093 — U.S. Treasury securities and obligations of U.S. Government corporations and agencies 18,451 18,451 — — Trading securities 107 107 — — Equity securities available-for-sale 4,509 3,436 — 1,073 Total Financial Assets $ 100,374 $ 21,994 $ 77,307 $ 1,073 Financial Liabilities Interest rate swap $ (608 ) $ — $ — $ (608 ) Total Financial Liabilities $ (608 ) $ — $ — $ (608 ) The table below presents a reconciliation for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the year ended December 31, 2017 (in thousands): For the year ended December 31, 2017 Equity Securities Available-for-Sale Interest Rate Swap Beginning balance $ 1,258 $ (1,030 ) Total gains or losses (realized and unrealized): Included in earnings — — Included in other comprehensive income 114 422 Purchases: 46 — Sales: (345 ) — Issuances: — — Settlements: — — Transfers in/(out) of Level 3 — — Ending balance $ 1,073 $ (608 ) The amount of total gains or losses for the period included in earnings attributable to the change in unrealized gains or losses relating to assets and liabilities still held as of December 31, 2017: $ — $ — For the year ended December 31, 2017, there were no assets or liabilities measured at fair values on a nonrecurring basis. The Company is exposed to certain risks in the normal course of its business operations. The primary risk that is managed through the use of derivatives is interest rate risk on floating rate borrowings. This risk is managed through the use of interest rate swap agreements which are designated as cash flow hedges. For cash flow hedges, the effective portion of the gain or loss on the interest rate swap is included as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged transaction is recognized in earnings. The Company does not hold or issue derivatives that are not designated as hedging instruments. See Note 8 for additional information about the interest rate swap agreements. The following methods and assumptions were used to estimate fair value of each class of financial instrument for which it is practical to estimate that value: Cash and cash equivalents — the carrying amount is a reasonable estimate of fair value. Fixed maturities held-to-maturity — the carrying amount is amortized cost; the fair values of the Company’s public fixed maturity securities that are classified as held-to-maturity are generally based on prices obtained from independent pricing services. Mortgage loans — the carrying amount is a reasonable estimate of fair value due to the restrictive nature and limited marketability of the mortgage notes. Policy loans — the carrying amount is a reasonable estimate of fair value. Company owned life insurance — the carrying amount is a reasonable estimate of fair value. Other invested assets — the carrying amount is a reasonable estimate of fair value. Other policyholder funds — the carrying amount is a reasonable estimate of fair value. Debt — the carrying amount is a reasonable estimate of fair value. The carrying amount and estimated fair value of the Company’s financial instruments as of March 31, 2018 and December 31, 2017 are as follows (in thousands): March 31, 2018 December 31, 2017 Assets and related instruments Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Held-to-maturity securities $ 1,573 $ 1,575 $ 1,616 $ 1,645 Mortgage loans 161 161 162 162 Policy loans 1,842 1,842 1,810 1,810 Company owned life insurance 4,835 4,835 4,974 4,974 Other invested assets 2,451 2,451 2,574 2,574 Liabilities and related instruments Other policyholder funds 1,705 1,705 1,706 1,706 Short-term notes payable and current portion of long-term debt 800 800 1,300 1,300 Long-term debt 14,342 14,342 14,339 14,339

Income Taxes	INCOME TAXES On December 22, 2017, the President signed the Tax Cuts and Jobs Act (TCJA), a comprehensive tax legislation which, among other things, reduced the Company's statutory federal income tax rate from 34% to 21% effective January 1, 2018. In addition to the reduction in tax rates, the TCJA makes broad and complex changes to the Internal Revenue Code that will introduce changes to many tax related exclusions, deductions and credits. Management believes that, based on its historical pattern of taxable income, the Company will produce sufficient income in the future to realize its deferred tax assets. The Company recognized net deferred tax asset positions of $1,123,000 at March 31, 2018 and $1,487,000 at December 31, 2017 . The tax effect of significant differences representing deferred tax assets and liabilities are as follows (dollars in thousands): As of March 31, 2018 As of December 31, 2017 General expenses $ 1,068 $ 1,069 Unearned premiums 1,295 1,269 Claims liabilities 469 484 AMT credit 788 1,575 Impairment on real estate owned 116 116 Unrealized losses on securities available-for-sale 95 — Unrealized loss on interest rate swaps 93 128 Deferred tax assets 3,924 4,641 Depreciation (85 ) (88 ) Deferred policy acquisition costs (1,686 ) (1,706 ) Pre-1984 policyholder surplus account (513 ) (529 ) Unrealized gains on securities available-for-sale — (831 ) Unrealized gains on equity securities (517 ) — Deferred tax liabilities (2,801 ) (3,154 ) Net deferred tax asset $ 1,123 $ 1,487 The appropriate income tax effects of changes in temporary differences are as follows (dollars in thousands): Three months ended 2018 2017 Deferred policy acquisition costs $ (20 ) $ (3 ) Unearned premiums (26 ) (62 ) General expenses 1 62 Depreciation (3 ) (4 ) Claims liabilities 15 (44 ) AMT credit 787 (23 ) Impact of repeal of special provision on pre-1984 policyholder surplus (16 ) — Unrealized gains on equity securities (43 ) — Deferred income tax expense (benefit) $ 695 $ (74 ) Total income tax expense (benefit) varies from amounts computed by applying current federal income tax rates to income or loss before income taxes. The reasons for these differences and the approximate tax effects are as follows: Three months ended 2018 2017 Federal income tax rate applied to pre-tax income/loss 21.0 % 34.0 % Dividends received deduction and tax-exempt interest (1.2 )% 2.6 % Company owned life insurance 4.6 % 2.0 % Small life deduction — % 19.3 % Other, net 1.1 % (2.1 )% Effective federal income tax rate 25.5 % 55.8 % The Company recognizes tax-related interest and penalties as a component of tax expense. The Company files income tax returns in the U.S. federal jurisdiction and various states. The Company is not subject to examinations by authorities related to its U.S. federal or state income tax filings for years prior to 2011. Tax returns have been filed through the year 2016.

On March 19, 2009, the Company entered into a forward swap effective September 17, 2012, with a notional amount of $3,000,000 and designated the swap as a hedge against changes in cash flows attributable to changes in the benchmark interest rate (LIBOR) associated with the subordinated debentures issued June 21, 2007. Quarterly, commencing September 17, 2012, under the terms of the forward swap, the Company will pay interest at a fixed rate of 7.02% until March 15, 2019. On May 26, 2010, the Company entered into a forward swap with a notional amount of $9,000,000 effective December 15, 2015, which hedges against changes in cash flows following the termination of the fixed rate period. Quarterly, commencing March 16, 2016 under the terms of the forward swap, the Company pays interest at a fixed rate of 8.49% until March 15, 2020. The swaps entered into in 2009 and 2010 have fair values of $39,000 (liability) and $402,000 (liability), respectively, for a total liability of $441,000 at March 31, 2018 ( $608,000 at December 31, 2017 ). The swap liability is reported as a component of other liabilities on the consolidated balance sheets. A net valuation gain of $132,000 (net of tax) is included in accumulated other comprehensive income related to the swap agreements at March 31, 2018 . A net valuation gain of $278,000 (net of tax) was included in accumulated other comprehensive income related to the swap at December 31, 2017 . We use dollar offset at the hedge's inception and for each reporting period thereafter to assess whether the derivative used in a hedging transaction is expected to be, and has been, effective in offsetting changes in the fair value of the hedged item. Since inception, no portion of the hedged item has been deemed ineffective. For all hedges, we discontinue hedge accounting if it is determined that a derivative is not expected to be, or has ceased to be, effective as a hedge. The Company’s interest rate swaps include provisions requiring the Company to post collateral when the derivative is in a net liability position. At March 31, 2018 , the Company has securities on deposit with fair market values of $1,425,000 ( $926,000 of which is posted as collateral). At December 31, 2017 , the Company had securities on deposit with fair market values of $1,446,000 (all of which is posted as collateral). See Note 4 for additional information about the interest rate swaps.

Reserve estimation can be an inherently uncertain process and reserves estimates can be revised up or down depending on changes in circumstances. Changes in prior years' reserve estimates are reflected in the results of operations in the year such changes are determined. The following table is a reconciliation of beginning and ending property and casualty reserve balances for claims and claim adjustment expense (dollars in thousands): Three months ended 2018 2017 Summary of claims and claim adjustment expense reserves Balance, beginning of year $ 7,075 $ 7,531 Less reinsurance recoverable on unpaid losses 327 1,184 Net balances at beginning of year 6,748 6,347 Net losses: Provision for claims and claim adjustment expenses for claims arising in current year 9,185 10,786 Estimated claims and claim adjustment expenses for claims arising in prior years (1,097 ) (751 ) Total increases 8,088 10,035 Claims and claim adjustment expense payments for claims arising in: Current year 5,527 7,090 Prior years 2,567 2,006 Total payments 8,094 9,096 Net balance at end of period 6,742 7,286 Plus reinsurance recoverable on unpaid losses 185 526 Claims and claim adjustment expense reserves at end of period $ 6,927 $ 7,812 The decline in claim and claim adjustment expense reserves before reinsurance recoverable is primarily due to the decrease in catastrophe losses during the period. The estimate for claims arising in prior years was reduced $1,097,000 in 2018 (reduced $751,000 in 2017) due to favorable loss development during the year on claims arising in prior years. Accident and Health Claim Reserves The Company, through its life insurance subsidiary, underwrites a limited number of short duration accident and health contracts. These claims are typically settled in three years or less and the reserve for unpaid claims totaled $430,000 at March 31, 2018 ( $367,000 at December 31, 2017). These claims are a component of policy and contract claims which totaled $913,000 at March 31, 2018 ( $903,000 at December 31, 2017).

Reinsurance Disclosures [Abstract]
Reinsurance	REINSURANCE The Company's insurance operations utilize reinsurance in the risk management process in order to limit losses, minimize exposure to large risks, provide additional capacity for future growth and effect business-sharing arrangements. Life reinsurance is placed through yearly renewable term coverage. Property and casualty reinsurance is placed on an excess of loss basis to cover losses from catastrophe events. Reinsurance ceded arrangements do not discharge the insurance subsidiaries as the primary insurer, except for cases involving a novation. Failure of re-insurers to honor their obligations could result in losses to the insurance subsidiaries. The insurance subsidiaries evaluate the financial conditions of their reinsurance companies and monitor concentrations of credit risk arising from similar geographic regions, activities, or economic characteristics of the companies to minimize their exposure to significant losses from reinsurance insolvencies. In the normal course of business, NSFC seeks to reduce the loss that may arise from catastrophes or other individually significant large loss events that cause unfavorable underwriting results or have adverse impacts on regulatory capital levels by re-insuring certain levels of risk in various areas of exposure with reinsurance companies. NSFC maintains a catastrophe reinsurance agreement to cover losses from catastrophic events, primarily hurricanes and tropical storms. Under the catastrophe reinsurance program, the Company retains the first $4,000,000 in losses from each catastrophe event. Catastrophe reinsurance coverage is maintained in three layers as follows: Layer Reinsurers' Limits of Liability First Layer 100% of $13,500,000 in excess of $4,000,000 retention Second Layer 100% of $25,000,000 in excess of $17,500,000 Third Layer 100% of $30,000,000 in excess of $42,500,000 Each reinsurance layer covers events occurring from January 1 through December 31 of the contract year. All significant reinsurance companies under the program carry A.M. Best ratings of A- (Excellent) or higher, or equivalent ratings. The Company's catastrophe reinsurance contract allows for one reinstatement. The Company maintains reinstatement premium protection (RPP) to cover reinstatement premiums incurred. The RPP further reduces risk from a major catastrophe and serves to protect the Company's capital position by reducing the modeled 100 year event net cost. Amounts recoverable from re-insurers are estimated in a manner consistent with the claim liability associated with the underlying insurance policies. Amounts paid for prospective reinsurance contracts are reported as prepaid reinsurance premiums and amortized over the remaining contract period. In the normal course of business, NSIC seeks to limit its exposure to loss on any single insured and to recover a portion of benefits paid by ceding reinsurance to reinsurance companies under excess coverage contracts. NSIC retains a maximum of $50,000 of coverage per individual life. Cost is amortized over the reinsurance contract period. At March 31, 2018 , the largest reinsurance recoverable of a single reinsurer was $ 340,000 ($ 322,000 at December 31, 2017). Amounts reported as ceded incurred losses were related to development of losses from prior year catastrophes.

Retirement Benefits [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS The Company and its subsidiaries have an established retirement savings plan (401K Plan). All full-time employees are eligible to participate, and all employer contributions are fully vested for employees who have completed 1,000 hours of service in the year of contribution. Company matching contributions for the three months ended March 31, 2018 and 2017 amounted to $45,000 and $57,000 , respectively. The Company contributes dollar-for-dollar matching contributions up to 5% of compensation subject to government limits. The Company established a non-qualified plan under which Company directors are allowed to defer all or a portion of directors' fees into various investment options. A supplemental executive retirement plan (SERP) covers named executive officers, with the Company contributing 15% of executive compensation to the plan. Contributions to the plan are fully vested upon the earlier of death, disability, change in control, or ten years of participation in the plan. Costs for amounts related to the non-qualified deferred compensation plans for the three months ended March 31, 2018 and 2017 amounted to an approximate $48,000 decrease and $83,000 increase in employee benefit related expenses, respectively. The Company and its subsidiaries established an Employee Stock Ownership Plan (ESOP) in January 2010, to enable eligible employees to acquire a proprietary interest in the Company's common stock and to provide retirement and other benefits to such employees. There were $232,000 costs incurred during the three months ended March 31, 2018 and $268,000 costs incurred during the three months ended March 31, 2017 related to ESOP plan contributions. All contributions were made in cash for purchase of Company shares in the open market. The Company has not allocated newly issued shares directly to the plan and the plan has no debt.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Segments	SEGMENTS The Company’s property and casualty insurance operations comprise one business segment. The property and casualty insurance segment primarily underwrites home insurance coverage with primary lines of business consisting of dwelling fire and extended coverage, homeowners (including mobile homeowners) and other liability. Management organizes the business utilizing a niche strategy focusing on lower valued dwellings and older homes that can be difficult to insure in the standard insurance market. Our chief decision makers (Chief Executive Officer, Chief Financial Officer and President) review results and operating plans making decisions on resource allocations on a company-wide basis. The Company’s products are primarily produced through independent agents within the states in which we operate. The Company’s life and accident and health operations comprise the second business segment. The life and accident and health insurance segment consists of two lines of business: traditional life insurance and supplemental accident and health insurance. Total assets by industry segment at March 31, 2018 and at December 31, 2017 are summarized below ( dollars in thousands ): Assets by industry segment Total P&C Insurance Operations Life Insurance Operations Non-Insurance Operations March 31, 2018 $ 146,074 $ 81,397 $ 59,972 $ 4,705 December 31, 2017 $ 146,438 $ 80,241 $ 60,709 $ 5,488 Premium revenues and operating income by business segment for the three months ended March 31, 2018 and 2017 are summarized below ( dollars in thousands ): Three months ended March 31, 2018 Total P&C Insurance Operations Life Insurance Operations Non-Insurance Operations REVENUE Net premiums earned $ 15,059 $ 13,531 $ 1,528 $ — Net investment income 781 251 516 14 Net realized investment gains (losses) (125 ) (174 ) 49 — Other income 161 160 1 — 15,876 13,768 2,094 14 BENEFITS AND EXPENSES Policyholder benefits paid 9,427 7,978 1,449 — Amortization of deferred policy acquisition costs 803 690 113 — Commissions 2,060 2,012 48 — General and administrative expenses 2,003 1,452 507 44 Taxes, licenses and fees 649 553 96 — Interest expense 302 — 12 290 15,244 12,685 2,225 334 Income (Loss) Before Income Taxes $ 632 $ 1,083 $ (131 ) $ (320 ) Three months ended March 31, 2017 Total P&C Insurance Operations Life Insurance Operations Non-Insurance Operations REVENUE Net premiums earned $ 15,040 $ 13,489 $ 1,551 $ — Net investment income 926 392 519 15 Net realized investment gains 160 — 160 — Other income 152 150 2 — 16,278 14,031 2,232 15 BENEFITS AND EXPENSES Policyholder benefits paid 11,146 9,918 1,228 — Amortization of deferred policy acquisition costs 945 694 251 — Commissions 2,093 2,024 69 — General and administrative expenses 1,797 1,275 279 243 Taxes, licenses and fees 689 592 97 — Interest expense 323 — 19 304 16,993 14,503 1,943 547 Income (Loss) Before Income Taxes $ (715 ) $ (472 ) $ 289 $ (532 ) The following table presents the Company’s gross and net premiums written for the property and casualty segment and the life and accident and health segment for the three months ended March 31, 2018 and 2017, respectively: Three months ended 2018 2017 Life, accident and health operations premiums written: Traditional life insurance $ 1,120 $ 1,145 Accident and health insurance 415 423 Gross life, accident and health 1,535 1,568 Reinsurance premium ceded (31 ) (29 ) Net life, accident and health premiums written $ 1,504 $ 1,539 Property and Casualty operations premiums written: Dwelling fire & extended coverage $ 9,553 $ 9,431 Homeowners (Including mobile homeowners) 5,312 5,627 Other liability 565 543 Gross property and casualty 15,430 15,601 Reinsurance premium ceded (1,154 ) (1,102 ) Net property and casualty written $ 14,276 $ 14,499 Consolidated gross premiums written $ 16,965 $ 17,169 Reinsurance premium ceded (1,185 ) (1,131 ) Consolidated net premiums written $ 15,780 $ 16,038 The following table presents the Company’s gross and net premiums earned for the property and casualty segment and the life and accident and health segment for the three months ended March 31, 2018 and 2017, respectively: Three months ended 2018 2017 Life, accident and health operations premiums earned: Traditional life insurance $ 1,144 $ 1,158 Accident and health insurance 415 422 Gross life, accident and health 1,559 1,580 Reinsurance premium ceded (31 ) (29 ) Net life, accident and health premiums earned $ 1,528 $ 1,551 Property and Casualty operations premiums earned: Dwelling fire & extended coverage $ 9,116 $ 8,816 Homeowners (Including mobile homeowners) 5,497 5,720 Other liability 530 513 Gross property and casualty 15,143 15,049 Reinsurance premium ceded (1,612 ) (1,560 ) Net property and casualty earned $ 13,531 $ 13,489 Consolidated gross premiums earned $ 16,702 $ 16,629 Reinsurance premium ceded (1,643 ) (1,589 ) Consolidated net premiums earned $ 15,059 $ 15,040

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	CONTINGENCIES In the ordinary course of business, the Company and its subsidiaries are routinely a defendant in or party to pending or threatened legal actions and proceedings related to the conduct of their insurance operations. These suits can involve alleged breaches of contracts, torts, including bad faith and fraud claims based on alleged wrongful or fraudulent acts of the Company's subsidiaries, and other miscellaneous causes of action. It is inherently difficult to predict the outcome of such matters, particularly when the claimant seeks very large or indeterminate damages or when the matters present novel legal theories or involve multiple parties. An accrued liability is established when loss contingencies are both probably and estimable. However, there is potential loss exposure in excess of any accrued amounts. The Company monitors pending matters for further development that could affect the amount of the accrued liability. The Company's property & casualty subsidiaries had two actions remaining in Texas filed in the aftermath of Hurricane Ike at December 31, 2017. These actions include individual lawsuits with allegations of underpayment of hurricane-related claims. The suits seek a variety of remedies, including actual and/or punitive damages in unspecified amounts and/or declaratory relief. In March of 2018 the Company was notified that the Texas Supreme Court denied a Writ of Application to review an unfavorable decision handed down by the Court of Appeals on one of the two remaining Ike claims. This claim was 95% reinsured by the Company's catastrophe reinsurance coverage and the amount of the settlement, net of reinsurance, did not have a material impact on these consolidated financial statements. The Company has reserves set up on litigated claims and the reserves are included in benefit and loss reserves.

Significant Accounting Polici25

Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	The accompanying consolidated financial statements include the accounts of The National Security Group, Inc. (the Company) and its wholly-owned subsidiaries: National Security Insurance Company (NSIC), National Security Fire and Casualty Company (NSFC) and NATSCO, Inc. (NATSCO). NSFC includes a wholly-owned subsidiary, Omega One Insurance Company (Omega). The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements have been included. All significant intercompany transactions and accounts have been eliminated. The financial information presented herein should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, which includes information and disclosures not presented herein.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Among the more significant estimates included in these consolidated financial statements are reserves for future life insurance policy benefits, liabilities for losses and loss adjustment expenses, reinsurance recoverable associated with loss and loss adjustment expense liabilities, deferred policy acquisition costs, deferred income tax assets and liabilities, assessments of other-than-temporary impairments on investments and accruals for contingencies. Actual results could differ from these estimates.
Earnings Per Share	Earnings per share of common stock is based on the weighted average number of shares outstanding during each year. The adjusted weighted average shares outstanding were 2,522,312 at March 31, 2018 and 2,517,339 at March 31, 2017. The Company did not have any dilutive securities as of March 31, 2018 and 2017.
Reclassifications	Certain 2017 amounts have been reclassified from the prior year consolidated financial statements to conform to the 2018 presentation.
Concentration of Credit Risk	The Company maintains cash balances which are generally held in non-interest bearing demand deposit accounts subject to FDIC insured limits of $250,000 per entity. At March 31, 2018 , the net amount exceeding FDIC insured limits was $ 3,654,000 at three financial institutions. The Company has not experienced any losses in such accounts. Management of the Company reviews financial information of financial institutions on a quarterly basis and believes the Company is not exposed to any significant credit risk on cash and cash equivalents. Policy receivables are reported at unpaid balances. Policy receivables are generally offset by associated unearned premium liabilities and are not subject to significant credit risk. Receivables from agents, less provision for credit losses, are composed of balances due from independent agents. At March 31, 2018 , the single largest balance due from one agent totaled $729,000 . Reinsurance contracts do not relieve the Company of its obligations to policyholders. A failure of a reinsurer to meet its obligation could result in losses to the insurance subsidiaries. Allowances for losses on reinsurance recoverables are established if amounts are believed to be uncollectible. At March 31, 2018 and December 31, 2017, no amounts were deemed uncollectible. The Company, at least annually, evaluates the financial condition of all reinsurers and evaluates any potential concentrations of credit risk. At March 31, 2018 , management does not believe the Company is exposed to any significant credit risk related to its reinsurance program.
Accounting Changes Not Yet Adopted and Recently Adopted Accounting Standards	Accounting Changes Not Yet Adopted Recognition and Measurement of Financial Assets and Financial Liabilities In February 2018, the Financial Accounting Standards Board (FASB) issued guidance to address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years beginning after June 15, 2018. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Leases In February 2016, the FASB issued guidance that requires lessees (for capital and operating leases) to recognize the lease liability and right-of-use asset at the commencement date of the lease. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Contingent Put and Call Options in Debt Instruments In March 2016, the FASB issued guidance that clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Financial Instruments - Credit Losses In June 2016, the FASB issued guidance that replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Receivables - Nonrefundable Fees and Other Costs In March 2017, the FASB issued guidance that shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. The guidance is effective for fiscal years beginning after December 15, 2018 and interim reporting periods within those fiscal years. The Company does not expect the adoption of this new guidance to have a significant impact on our financial position, results of operations or cash flows. Derivatives and Hedging In August 2017, the FASB issued guidance that amends and simplifies hedge accounting guidance in order to enable entities to better portray the economic results of their risk management activities. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted. The Company is currently evaluating the impact of the standard on its consolidated financial statements and related disclosures. Recently Adopted Accounting Standards Income Statement - Reporting Comprehensive Income In February 2018, the Financial Accounting Standards Board (FASB) issued guidance that allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The guidance eliminates the stranded tax effects resulting from the Tax Cuts and Jobs Act and improves the usefulness of information reported to financial statement users. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted. The Company adopted this guidance as of December 31, 2017. The adoption of this guidance resulted in a $435,000 reclassification to accumulated other comprehensive income from retained earnings related to stranded tax effects resulting from the Tax Cuts and Jobs Act. Revenue from Contracts with Customers In May 2014, FASB issued guidance on a comprehensive new revenue recognition standard. This standard will not impact accounting for insurance contracts, leases, financial instruments and guarantees. For those contracts that are impacted by the new guidance, the guidance will require an entity to recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to, in exchange for those goods or services. The guidance requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued a deferral of the effective date by one year. This guidance is effective retrospectively for fiscal years beginning after December 15, 2017 and interim periods within those years. Early adoption of this standard is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Insurance contracts are specifically scoped out of this new guidance. The Company does not have policy fees or any material services that may be subject to the new revenue recognition guidance. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have an impact on its condensed consolidated financial statements. Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued guidance that requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The guidance requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset. The guidance eliminates the requirement for public companies to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. This guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance resulted in a $2,107,000 reclassification to retained earnings from accumulated other comprehensive income related to accumulated unrealized gains on equity securities as well as recognition of a $162,000 loss, net of tax, related to the change in value of equity securities. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued guidance that clarifies how certain cash receipts and cash payments shall be presented and classified in the statement of cash flows. This guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The guidance is effective for annual and interim reporting periods beginning after December 15, 2017. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows. Compensation - Stock Compensation In May 2017, the FASB issued guidance to provide clarity and reduce diversity in practice as well as cost and complexity when there is a change in the terms or conditions of a share-based payment award. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2018. The adoption of this guidance did not have a significant impact on our financial position, results of operations or cash flows.
Consolidation, Variable Interest Entities	The Company holds a passive interest in a limited partnership that is considered to be a Variable Interest Entity (VIE) under the provisions of ASC 810 Consolidation . The Company is not the primary beneficiary of the entity and is not required to consolidate under ASC 810. The entity is a private placement investment fund formed for the purpose of investing in private equity investments. The Company owns less than 1% of the limited partnership. The carrying value of the investment totals $142,000 and is included as a component of Other Invested Assets in the accompanying consolidated balance sheets.
Marketable Securities	In evaluating whether or not the equity loss positions were other-than-temporary impairments, Management evaluated financial information on each company and where available, reviewed analyst reports from at least two independent sources. For securities in an unrealized loss position, the Company assesses whether the Company has the intent to sell the security or more-likely-than-not will be required to sell the security before the anticipated recovery. If either of these conditions is met, the Company is required to recognize an other-than-temporary impairment with the entire unrealized loss reported in earnings. For securities in an unrealized loss position that do not meet these conditions, the Company assesses whether the impairment of a security is other-than-temporary. If the impairment is determined to be other-than-temporary, the Company is required to separate the other-than-temporary impairments into two components: the amount representing the credit loss and the amount related to all other factors. The credit loss is the portion of the amortized book value in excess of the net present value of the projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. The credit loss component of other-than-temporary impairments is reported in earnings, whereas the amount relating to factors other than credit losses are recorded in other comprehensive income, net of taxes.
Fair Values of Financial Instruments	The following methods and assumptions were used to estimate fair value of each class of financial instrument for which it is practical to estimate that value: Cash and cash equivalents — the carrying amount is a reasonable estimate of fair value. Fixed maturities held-to-maturity — the carrying amount is amortized cost; the fair values of the Company’s public fixed maturity securities that are classified as held-to-maturity are generally based on prices obtained from independent pricing services. Mortgage loans — the carrying amount is a reasonable estimate of fair value due to the restrictive nature and limited marketability of the mortgage notes. Policy loans — the carrying amount is a reasonable estimate of fair value. Company owned life insurance — the carrying amount is a reasonable estimate of fair value. Other invested assets — the carrying amount is a reasonable estimate of fair value. Other policyholder funds — the carrying amount is a reasonable estimate of fair value. Debt — the carrying amount is a reasonable estimate of fair value. Our available-for-sale securities consists of fixed maturity and equity securities which are recorded at fair value in the accompanying consolidated balance sheets. The change in the fair value of these investments, unless deemed to be other-than-temporarily impaired, is recorded as a component of other comprehensive income. We are permitted to elect to measure financial instruments and certain other items at fair value, with the change in fair value recorded in earnings. We elected not to measure any eligible items using the fair value option. Accounting standards define fair value as the price that would be received to sell an asset or would be paid to transfer a liability in an orderly transaction between market participants at the measurement date, and establishes a framework to make the measurement of fair value more consistent and comparable. In determining fair value, we primarily use prices and other relevant information generated by market transactions involving identical or comparable assets. The Company categorizes assets and liabilities carried at their fair value based upon a fair value hierarchy: Level 1 – Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 1 assets and liabilities consist of money market fund deposits and certain of our marketable debt and equity instruments, including equity instruments offsetting deferred compensation, that are traded in an active market with sufficient volume and frequency of transactions. Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include certain of our marketable debt and equity instruments with quoted market prices that are traded in less active markets or priced using a quoted market price for similar instruments. Level 2 assets also include marketable equity instruments with security-specific restrictions that would transfer to the buyer, marketable debt instruments priced using indicator prices which represent non-binding market consensus prices that can be corroborated by observable market quotes, as well as derivative contracts and debt instruments priced using inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Marketable debt instruments in this category generally include commercial paper, bank time deposits, repurchase agreements for fixed-income instruments, and a majority of floating-rate notes, corporate bonds, and municipal bonds. Level 3 - Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. Level 3 assets and liabilities include marketable debt instruments, non-marketable equity investments, derivative contracts, and company issued debt with values are determined using inputs that are both unobservable and significant to the values of the instruments being measured. Level 3 assets also include marketable debt instruments that are priced using indicator prices that we were unable to corroborate with observable market quotes. Marketable debt instruments in this category generally include asset-backed securities and certain floating-rate notes, corporate bonds, and municipal bonds. Fixed maturities available-for-sale — The fair values of the Company’s public fixed maturity securities are generally based on prices obtained from independent pricing services. Consistent with the fair value hierarchy described above, securities with validated quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. Trading securities — Trading securities consist primarily of mutual funds whose fair values are determined consistent with similar instruments described above under “Fixed Maturities” and below under “Equity Securities.” Equity securities — Equity securities consist principally of investments in common and preferred stock of publicly traded companies and privately traded securities. The fair values of our publicly traded equity securities are based on quoted market prices in active markets for identical assets and are classified within Level 1 in the fair value hierarchy. Estimated fair values for our privately traded equity securities require a substantial level of judgment. Privately traded equity securities are classified within Level 3. Interest rate swaps — Interest rate swaps are recorded at fair value either as assets, within other assets or as liabilities, within other liabilities. The fair values of our interest rate swaps are provided by a third-party broker and are classified within Level 3.
Derivatives	The Company is exposed to certain risks in the normal course of its business operations. The primary risk that is managed through the use of derivatives is interest rate risk on floating rate borrowings. This risk is managed through the use of interest rate swap agreements which are designated as cash flow hedges. For cash flow hedges, the effective portion of the gain or loss on the interest rate swap is included as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged transaction is recognized in earnings. The Company does not hold or issue derivatives that are not designated as hedging instruments. We use dollar offset at the hedge's inception and for each reporting period thereafter to assess whether the derivative used in a hedging transaction is expected to be, and has been, effective in offsetting changes in the fair value of the hedged item. Since inception, no portion of the hedged item has been deemed ineffective. For all hedges, we discontinue hedge accounting if it is determined that a derivative is not expected to be, or has ceased to be, effective as a hedge. The swap liability is reported as a component of other liabilities on the consolidated balance sheets.
Reinsurance	Amounts recoverable from re-insurers are estimated in a manner consistent with the claim liability associated with the underlying insurance policies. Amounts paid for prospective reinsurance contracts are reported as prepaid reinsurance premiums and amortized over the remaining contract period. In the normal course of business, NSIC seeks to limit its exposure to loss on any single insured and to recover a portion of benefits paid by ceding reinsurance to reinsurance companies under excess coverage contracts. NSIC retains a maximum of $50,000 of coverage per individual life. Cost is amortized over the reinsurance contract period. The Company's insurance operations utilize reinsurance in the risk management process in order to limit losses, minimize exposure to large risks, provide additional capacity for future growth and effect business-sharing arrangements. Life reinsurance is placed through yearly renewable term coverage. Property and casualty reinsurance is placed on an excess of loss basis to cover losses from catastrophe events. Reinsurance ceded arrangements do not discharge the insurance subsidiaries as the primary insurer, except for cases involving a novation. Failure of re-insurers to honor their obligations could result in losses to the insurance subsidiaries. The insurance subsidiaries evaluate the financial conditions of their reinsurance companies and monitor concentrations of credit risk arising from similar geographic regions, activities, or economic characteristics of the companies to minimize their exposure to significant losses from reinsurance insolvencies. In the normal course of business, NSFC seeks to reduce the loss that may arise from catastrophes or other individually significant large loss events that cause unfavorable underwriting results or have adverse impacts on regulatory capital levels by re-insuring certain levels of risk in various areas of exposure with reinsurance companies. NSFC maintains a catastrophe reinsurance agreement to cover losses from catastrophic events, primarily hurricanes and tropical storms
Business Segment	The Company’s life and accident and health operations comprise the second business segment. The life and accident and health insurance segment consists of two lines of business: traditional life insurance and supplemental accident and health insurance. The Company’s property and casualty insurance operations comprise one business segment. The property and casualty insurance segment primarily underwrites home insurance coverage with primary lines of business consisting of dwelling fire and extended coverage, homeowners (including mobile homeowners) and other liability.
