Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying condensed 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 condensed 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 condensed 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, 2014, 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Among the more significant estimates included in these condensed 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 2,508,551 in 2015 and 2,495,770 in 2014. Reclassifications Certain 2014 amounts have been reclassified from the prior year consolidated financial statements to conform to the 2015 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 June 30, 2015, the net amount exceeding FDIC insured limits was $3,998,000 at one financial institution. 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 June 30, 2015, the single largest balance due from one agent totaled $1,314,000. Reinsurance contracts do not relieve the Company of its obligations to policyholders. A failure of a reinsurer to meet their obligation could result in losses to the insurance subsidiaries. Allowances for losses are established if amounts are believed to be uncollectible. At June 30, 2015 and December 31, 2014, 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 June 30, 2015, management does not believe the Company is exposed to any significant credit risk related to its reinsurance program. Accounting Changes Not Yet Adopted Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (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. Although insurance contracts are specifically scoped out of this new guidance, the Company has minor services that may be subject to the new revenue recognition guidance and are still in the process of evaluating the impact, if any, the guidance may have on its consolidated financial statements. Presentation of Financial Statements - Going Concern In August 2014, the FASB issued guidance on determining when and how to disclose going concern uncertainties in the financial statements, and requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The updated guidance is effective for annual periods ending after December 15, 2016 and interim periods thereafter. Early adoption is permitted. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items In January 2015, the FASB issued guidance that eliminates from GAAP the concept of extraordinary items. The guidance is effective for fiscal periods ending after December 15, 2015 and interim periods thereafter. Early adoption is permitted. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Amendments to the Consolidation Analysis In February 2015, the FASB issued additional guidance regarding the consolidation of certain legal entities. The guidance modifies the evaluation of whether or not limited partnerships and similar legal entities are variable interest entities (VIEs) and the consolidation analysis of entities involved with VIEs, particularly those that have fee arrangements and related party relationships. This guidance is effective for fiscal years beginning after December 15, 2015. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Disclosure about Short-Duration Contracts In May 2015, the FASB issued guidance that enhances disclosure about short-duration insurance liabilities to help users understand the nature, amount, timing and uncertainty of future cash flows related to insurance liabilities and the effect of those cash flows on the statement of comprehensive income. This guidance is effective for annual periods beginning after December 15, 2015 and for interim periods within annual periods beginning after December 15, 2016. The Company does not expect the adoption to have a material impact on its financial position or results of operations. Recently Adopted Accounting Standards Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures In June 2014, the FASB issued guidance requiring secured borrowing accounting treatment for repurchase-to-maturity transactions and provides guidance on accounting for repurchase financing arrangements. This ASU is effective for interim and annual reporting periods beginning after December 15, 2014. The Company adopted this standard on January 1, 2015. The Company is the counter party to repurchase agreements and as such, the adoption did not have a material impact on its financial position or results of operations. Reporting Discontinued Operations and Disclosure of Disposals of Components of an Entity In April 2014, the FASB issued guidance which modifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. Also, this update requires additional financial statement disclosures about discontinued operations, as well as disposals of an individually significant component of an entity that do not qualify for discontinued operations presentation. This ASC update is effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual and interim periods beginning on or after December 15, 2014 and for all businesses that, on acquisition, are classified as held for sale that also occur within interim and annual periods beginning on or after December 15, 2014. The Company adopted this standard on January 1, 2015. The Company has no discontinued operations, and the adoption of this standard did not have a material impact on its financial position or results of operations.
