Summary of Significant Accounting Policies (Policies)	Dec. 31, 2014
Accounting Policies [Abstract]
General	General First Acceptance Corporation (the “Company”) is a holding company based in Nashville, Tennessee with operating subsidiaries whose primary operations include the selling, servicing and underwriting of non-standard personal automobile insurance and related products. The Company writes non-standard personal automobile insurance in 12 states and is licensed as an insurer in 13 additional states. The Company issues policies of insurance through three wholly-owned subsidiaries: First Acceptance Insurance Company, Inc., First Acceptance Insurance Company of Georgia, Inc. and First Acceptance Insurance Company of Tennessee, Inc. (collectively, the “Insurance Companies”).
Basis of Consolidation and Reporting	Basis of Consolidation and Reporting The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries which are all wholly owned. The accounts of First Acceptance Statutory Trust I (“FAST I”) are not consolidated since it does not meet the requirements for consolidation of FASB ASC 810, Consolidation (see Note 10). These financial statements have been prepared in conformity with U.S. generally accepted accounting principles. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. It also requires disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported revenues and expenses during the period. Actual results could differ from those estimates.
Investments	Investments Investments, available-for-sale at fair value, include bonds with fixed principal payment schedules and mortgage-backed securities which are amortized using the retrospective method. These securities and investments in mutual funds are carried at fair value with the corresponding unrealized appreciation or depreciation, net of deferred income taxes, reported in other comprehensive income (loss). Premiums and discounts on collateralized mortgage obligations (“CMOs”) are amortized over a period based on estimated future principal payments, including prepayments. Prepayment assumptions are reviewed periodically and adjusted to reflect actual prepayments and changes in expectations. The most significant determinants of prepayments are the difference between interest rates on the underlying mortgages and the current mortgage loan rates and the structure of the security. Other factors affecting prepayments include the size, type and age of underlying mortgages, the geographic location of the mortgaged properties and the credit worthiness of the borrowers. Variations from anticipated prepayments will affect the life and yield of these securities. Investment securities are exposed to various risks such as interest rate, market and credit risk. Fair values of securities fluctuate based on changing market conditions. Significant changes in market conditions could materially affect portfolio value in the near term. Management reviews investments for impairment on a quarterly basis. Fair values of investments are based on prices quoted in the most active market for each security. If quoted prices are not available, fair value is estimated based on the fair value of comparable securities, discounted cash flow models or similar methods. Any decline in the fair value of any available-for-sale security below cost that is deemed to be other-than-temporary would result in a reduction in the amortized cost of the security. If management can assert that it does not intend to sell an impaired fixed maturity security and it is more likely than not that it will not have to sell the security before recovery of its amortized cost basis, then an entity must separate other-than-temporary impairments (“OTTI”) into the following two components: (i) the amount related to credit losses (charged against income) and (ii) the amount related to all other factors (recorded in other comprehensive income). The credit-related portion of an OTTI is measured by comparing a security’s amortized cost to the present value of its current expected cash flows discounted at its effective yield prior to the impairment charge. If management intends to sell an impaired security, or it is more likely than not that it will be required to sell the security before recovery, an impairment charge is required to reduce the amortized cost of that security to fair value. Realized gains and losses on sales and redemptions of securities are computed based on specific identification.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of bank demand deposits and highly-liquid investments including overnight collateralized repurchase agreements. All investments with maturities of three months or less at the date of purchase are considered cash equivalents.
Other Investments	Other Investments Other investments consist of limited partnership interests and an investment in the common stock of a real estate investment trust (“REIT”). Limited partnership interests are recorded at net asset value or the equity method of accounting if the Company is deemed to have significant influence as a result of its ownership percentage. Based on the underlying investments of the limited partnerships, their carrying value approximates fair value. Valuations are based upon the GAAP financial statements of the partnerships which are required to be audited annually. The common stock of the REIT is recorded at a fair value with the corresponding unrealized appreciation or depreciation, net of deferred income taxes, reported in other comprehensive income (loss). The change in net asset value of limited partnership interests and any dividends paid by the REIT are recorded in investment income in the consolidated statements of comprehensive income (loss).
Revenue Recognition	Revenue Recognition Insurance premiums earned include policy and renewal fees and are recognized on a pro-rata basis over the respective terms of the policies. Written premiums are recorded as of the effective date of the policies for the full policy premium, although most policyholders elect to pay on a monthly installment basis. Premiums and fees are generally collected in advance of providing risk coverage, minimizing the Company’s exposure to credit risk. Premiums receivable are recorded net of an estimated allowance for uncollectible amounts. Commission and fee income includes installment fees recognized when billed, commissions and fees from ancillary products recognized on a pro-rata basis over the respective terms of the contracts, and commissions and related policy fees, written for third-party insurance companies, recognized, at the date the customer is initially billed or as of the effective date of the insurance policy, whichever is later.
Income Taxes	Income Taxes Income taxes are accounted for under the liability 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 the deferred taxes is established based upon management’s estimate of whether it is more likely than not that the Company would not realize tax benefits in future periods to the full extent available. Changes in the valuation allowance are recognized in income during the period in which the circumstances that cause such a change in management’s estimate occur. The Company accounts for income tax uncertainties under the provisions of FASB ASC 740, Income Taxes. The Company has recognized no additional liability or reduction in deferred tax assets for unrecognized tax benefits at December 31, 2014 and 2013. Any interest and penalties incurred in connection with income taxes are recorded as a component of the provision for income taxes. The Company is generally not subject to U.S. federal, state or local income tax examinations by tax authorities for taxable years prior to 2010.
Property and Equipment	Property and Equipment Property and equipment are initially recorded at cost. Depreciation is provided over the estimated useful lives of the assets (generally ranging from three to seven years) using the straight-line method. Leasehold improvements are amortized over the shorter of the lives of the respective leases or the service lives of the improvements. Repairs and maintenance are charged to expense as incurred. Equipment under capitalized lease obligations is stated at the present value of the minimum lease payments at the beginning of the lease term.
Foreclosed Real Estate Held for Sale	Foreclosed Real Estate Held for Sale Foreclosed real estate held for sale is recorded at the lower of cost or fair value less estimated costs to sell. The Company periodically reviews its portfolio of foreclosed real estate held for sale using current information including (i) independent appraisals, (ii) general economic factors affecting the area where the property is located, (iii) recent sales activity and asking prices for comparable properties and (iv) costs to sell and/or develop that would serve to lower the expected proceeds from the disposal of the real estate. Gains (losses) realized on liquidation are recorded directly to operations and included in revenues. Foreclosed real estate held for sale assets of $0.8 million at December 31, 2014 and 2013 are included within other assets in the accompanying consolidated balance sheets.
Deferred Acquisition Costs	Deferred Acquisition Costs Deferred acquisition costs include premium taxes and other variable underwriting and direct sales costs incurred in connection with writing successful new and renewal business. These costs are deferred and amortized over the policy period in which the related premiums are earned, to the extent that such costs are deemed recoverable from future unearned premiums and anticipated investment income. Advertising costs are expensed when incurred and are not a part of deferred acquisition costs. Amortization expense for the years ended December 31, 2014, 2013 and 2012 was $11.4 million, $11.1 million and $11.4 million, respectively, and is included within insurance operating expenses in the accompanying consolidated statements of operations and comprehensive income (loss).
Identifiable Intangible Assets	Identifiable Intangible Assets Identifiable intangible assets are attributable to the Company’s insurance operations and were initially recorded at their estimated fair values at the date of acquisition. Identifiable intangible assets, primarily comprised of trade names, having an indefinite useful life, are not amortized for financial statement purposes. The Company performs required annual impairment tests of its identifiable intangible assets as of June 30^th of each fiscal year. In the event that facts and circumstances indicate that the identifiable intangible assets may be impaired, an interim impairment test would be required. The Company follows the guidelines of ASU 2012-02, Intangibles — Goodwill and Other (Topic 350), which allows companies to waive comparing the fair value of indefinite-lived intangible assets to their carrying amounts in assessing the recoverability of these assets if, based on qualitative factors, it is more likely than not that the fair value of the indefinite-lived intangible assets is greater than their carrying amounts.
Loss and Loss Adjustment Expense Reserves	Loss and Loss Adjustment Expense Reserves Loss and loss adjustment expense reserves are undiscounted and represent case-basis estimates of reported losses and estimates based on certain actuarial assumptions regarding the past experience of reported losses, including an estimate of losses incurred but not reported. Management believes that the loss and loss adjustment reserves are adequate to cover the ultimate associated liability. However, such estimates may be more or less than the amount ultimately paid when the claims are finally settled.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In October 2010, the FASB issued Accounting Standards Update (“ASU”) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts (a consensus of the FASB Emerging Issues Task Force) (Topic 944), which clarifies what costs should be deferred by insurance companies when issuing or renewing insurance contracts. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2011. The Company adopted this standard on a prospective basis on January 1, 2012 and, in connection therewith, recognized additional expense of $0.4 million over the first six months of 2012, consistent with the Company’s insurance policy terms and estimated deferred acquisition costs amortization period. In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which amends certain measurement and disclosure requirements related to fair value measurements to improve consistency with international reporting standards. The Company adopted the provisions of this guidance in the quarter ended March 31, 2012. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations. In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income, which requires a company to present components of net income and other comprehensive income in one continuous statement or in two separate, but consecutive statements. There are no changes to the components that are recognized in net income or other comprehensive income under current GAAP. The Company adopted the provisions of this guidance in the quarter ended March 31, 2012. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations, other than the presentation thereof. In September 2011, the FASB issued ASU 2011-08, Intangibles — Goodwill and Other (Topic 350), which allows companies to waive comparing the fair value of a reporting unit to its carrying amount in assessing the recoverability of goodwill if, based on qualitative factors, it is more likely than not that the fair value of a reporting unit is greater than its carrying amount. The Company adopted the provisions of this guidance in the quarter ended March 31, 2012. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations. In July 2012, the FASB issued ASU 2012-02, Intangibles — Goodwill and Other (Topic 350), which allows companies to waive comparing the fair value of indefinite-lived intangible assets to their carrying amounts in assessing the recoverability of these assets if, based on qualitative factors, it is more likely than not that the fair value of the indefinite-lived intangible assets is greater than their carrying amounts. The Company early adopted the provisions of this guidance in the quarter ended June 30, 2012. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations. In February 2013, the FASB issued ASU No. 2013-02, Presentation of Comprehensive Income, which requires a company to provide information about the amounts reclassified out of accumulated other comprehensive income by component. There are no changes to the components that are recognized in net income or other comprehensive income under current GAAP. The Company adopted the provisions of this guidance in the quarter ended March 31, 2013. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations, other than the presentation thereof. In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued a new revenue recognition standard, ASU No. 2014-09, “Revenue from Contracts with Customers”, that will supersede virtually all revenue recognition guidance in GAAP and International Financial Reporting Standards (“IFRS”). This guidance has an effective date for public companies for annual and interim periods beginning after December 15, 2016, with early adoption not permitted. The standard is intended to increase comparability across industries and jurisdictions. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The new standard will not change accounting guidance for insurance contracts. However, the Company is currently evaluating this guidance as it relates to non-insurance arrangements and any impact it will have on future consolidated financial statements. At this time the impact is unknown. In June 2014, the FASB made a decision to require insurance companies to make additional disclosures about short-term duration contracts. This guidance has an effective date for public companies for annual reporting periods beginning after December 15, 2014 and interim reporting periods beginning after December 15, 2015, with early adoption permitted. The Company believes that it will be reasonably able to comply with these requirements.
Supplemental Cash Flow Information	Supplemental Cash Flow Information During the years ended December 31, 2014, 2013 and 2012, the Company paid $0.7 million, $0.5 million and $0.2 million, respectively, in income taxes and $1.7 million, $1.7 million and $3.0 million, respectively, in interest.
Basic and Diluted Net Income (Loss) Per Share	Basic and Diluted Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of common shares, while diluted net income (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of such common shares and dilutive share equivalents. Dilutive share equivalents result from the assumed exercise of employee stock options and vesting of restricted common stock and are calculated using the treasury stock method.
