Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Atlas Financial Holdings, Inc. (“Atlas” or “We” or the “Company”) commenced operations on December 31, 2010. The primary business of Atlas is underwriting commercial automobile insurance in the United States (“U.S.”), with a niche market orientation and focus on insurance for the “light” commercial automobile sector. This sector includes taxi cabs, non-emergency para-transit, limousine, livery, including certain transportation network companies (“TNC”) drivers/operators, and business autos. Automobile insurance products provide insurance coverage in three major areas: liability, accident benefits and physical damage. Liability insurance provides coverage, subject to policy terms and conditions where the insured is determined to be responsible and/or liable for an automobile accident, for the payment for injuries and property damage to third parties. Accident benefit policies or personal injury protection policies provide coverage for loss of income, medical and rehabilitation expenses for insured persons who are injured in an automobile accident, regardless of fault. Physical damage coverage subject to policy terms and conditions provides for the payment of damages to an insured automobile arising from a collision with another object or from other risks such as fire or theft. In the short run, automobile physical damage and liability coverage generally provides more predictable results than automobile accident benefit or personal injury insurance. Atlas’ business is carried out through its “Insurance Subsidiaries”: American Country Insurance Company (“American Country”), American Service Insurance Company, Inc. (“American Service”), Gateway Insurance Company (“Gateway”), and Global Liberty Insurance Company of New York (“Global Liberty”); and other non-insurance company subsidiaries: Anchor Group Management Inc. (“AGMI”), Plainview Premium Finance Company, Inc. (“Plainview Delaware”), UBI Holdings Inc. (“UBI Holdings”) and UBI Holdings’ wholly-owned subsidiaries, optOn Digital IP Inc. (“OOIP”) and optOn Insurance Agency Inc. (“optOn” and together with OOIP and UBI Holdings, “UBI”). The Insurance Subsidiaries distribute their insurance products through AGMI, which has contracted a network of retail independent agents. Together, the Insurance Subsidiaries are licensed to write property and casualty (“P&C”) insurance in 49 states and the District of Columbia in the U.S. Atlas’ core products are actively distributed in 42 of those states plus the District of Columbia. The Insurance Subsidiaries and the Company’s other non-insurance subsidiaries share common management and operating infrastructure. See “Explanatory Note” and “Part I, Item 2, 2019 Developments” for certain developments with respect to the Company and the Insurance Subsidiaries during the second quarter and subsequent to June 30, 2019. Atlas’ ordinary voting common shares are listed on the NASDAQ under the symbol “AFH”. Basis of Presentation These statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Atlas and the entities it controls. All significant intercompany accounts and transactions have been eliminated. The results for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the full calendar year. The accompanying unaudited condensed consolidated financial statements, in accordance with Securities and Exchange Commission (“SEC”) rules for interim periods, do not include all of the information and notes required by U.S. GAAP for complete financial statements and should be read in conjunction with Atlas’ Annual Report on Form 10-K for the year ended December 31, 2018 , which provides a more complete understanding of the Company’s accounting policies, financial position, operating results, business properties, and other matters. Atlas has consistently applied the same accounting policies throughout all periods presented. Estimates and Assumptions The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and changes in estimates are recorded in the accounting period in which they are determined. The liability for unpaid claims and claims adjustment expenses and related amounts recoverable from reinsurers represent the most significant estimates in the accompanying condensed consolidated financial statements, and differences between such estimates and actual results could be material. Significant estimates in the accompanying financial statements also include the fair values of investments, deferred policy acquisition cost recoverability, and deferred tax asset valuation. Seasonality The P&C insurance business is seasonal in nature. While Atlas’ net premiums earned are generally stable from quarter to quarter, Atlas’ gross premiums written follow the common renewal dates for the “light” commercial risks that represent its core lines of business. For example, January 1 and March 1 are common taxi cab renewal dates in Illinois and New York, respectively. Our New York “excess taxi program” has an annual renewal date in the third quarter. Net underwriting results are driven mainly by the timing and nature of claims, which can vary widely. Operating Segments The Company operates in one business segment, the P&C insurance business.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	New Accounting Standards With the exception of the accounting and disclosure pronouncements discussed below, there have been no recent pronouncements or changes in pronouncements during the six months ended June 30, 2019 , as compared to those described in our Annual Report on Form 10-K for the twelve months ended December 31, 2018 , that are of significance or potential significance to Atlas. Pertinent Accounting Standard Updates (“ASUs”) are issued from time to time by the Financial Accounting Standards Board (“FASB”) and are adopted by the Company as they become effective. All recently issued accounting pronouncements with effective dates prior to July 1, 2019 have been adopted by the Company. Recently Adopted Leases In March 2019, December 2018, July 2018 and February 2016, the FASB issued ASU 2019-01 Leases (Topic 842) Codification Improvements, ASU 2018-20 Leases (Topis 842) Narrow-Scope Improvements for Lessors, ASU 2018-11 Leases (Topic 842): Targeted Improvements and ASU 2018-10 Codification Improvements to Topic 842, Leases and ASU 2016-02, Leases (Topic 842), respectively. The provisions of these updates impact the classification criteria, disclosure requirements, and other specific transactions in lease accounting. The updates require either the use of a modified retrospective approach, which requires leases to be measured at the beginning of the earliest period presented, or the transition method, which requires entities to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted the updates on January 1, 2019 using the transition method with no change to comparative periods. See ‘Part I, Item 1, Note 16, Leases, for further discussion of the future lease commitments. The adoption of these updates resulted in the recognition of both a right-of-use asset and lease liability in the amounts of approximately $2.6 million and $3.2 million , respectively. There was no impact to any of Atlas’ current financial covenants as a result of the increase to reported liabilities. Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance shortens the amortization period to the earliest call date for certain purchased callable debt securities held at a premium that have explicit, noncontingent call features and are callable at a fixed price and preset date. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. The Company adopted the update on January 1, 2019 with no impact on the Company’s consolidated financial statements because Atlas’ callable debt securities, that are held at a premium, are amortized to the earliest call date, which is consistent with current accounting treatment.

Earnings per common share diluted is computed by dividing net income by the weighted average number of common shares outstanding for each period plus the incremental number of shares added as a result of converting dilutive potential ordinary voting common shares, calculated using the treasury stock method (or, in the case of the convertible preferred shares, using the “if-converted” method). Atlas’ dilutive potential ordinary voting common shares consist of outstanding stock options to purchase ordinary voting common shares. The effects of these convertible instruments are excluded from the computation of earnings per common share diluted in periods in which the effect would be anti-dilutive. For the three and six months ended June 30, 2019 , all exercisable stock options were deemed to be anti-dilutive. For the three and six months ended June 30, 2018 , all exercisable stock options were deemed to be dilutive.

Atlas assesses, on a quarterly basis, whether there is evidence that a financial asset or group of financial assets is impaired. An investment is considered impaired when the fair value of the investment is less than its cost or amortized cost. When an investment is impaired, the Company must make a determination as to whether the impairment is other-than-temporary. Management performs a quarterly analysis of Atlas’ investment holdings to determine if declines in fair value are other-than-temporary. The analysis includes some or all of the following procedures as deemed appropriate by management: • identifying all security holdings in unrealized loss positions that have existed for at least six months or other circumstances that management believes may impact the recoverability of the security; • obtaining a valuation analysis from third party investment managers regarding these holdings based on their knowledge, experience and other market-based valuation techniques; • reviewing the trading range of certain securities over the preceding calendar period; • assessing whether declines in market value are other-than-temporary for debt security holdings based on credit ratings from third party security rating agencies; and • determining the necessary provision for declines in market value that are considered other-than-temporary based on the analyses performed. The risks and uncertainties inherent in the assessment methodology utilized to determine declines in market value that are other-than-temporary include, but may not be limited to, the following: • the opinion of professional investment managers could prove to be incorrect; • the past trading patterns of individual securities may not reflect future valuation trends; • the credit ratings assigned by independent credit rating agencies may prove to be incorrect due to unforeseen or unknown facts related to a company’s financial situation; and • the debt service pattern of non-investment grade securities may not reflect future debt service capabilities and may not reflect a company’s unknown underlying financial problems. Under U.S. GAAP, with respect to an investment in an impaired debt security, other-than-temporary impairment (“OTTI”) occurs if (a) there is intent to sell the debt security, (b) it is more likely than not it will be required to sell the debt security before its anticipated recovery, or (c) it is probable that all amounts due will be unable to be collected such that the entire cost basis of the security will not be recovered. If Atlas intends to sell the debt security, or will more likely than not be required to sell the debt security before the anticipated recovery, a loss in the entire amount of the impairment is reflected in net investment gains (losses) on investments in the condensed consolidated statements of (loss) income . If Atlas determines that it is probable it will be unable to collect all amounts and Atlas has no intent to sell the debt security, a credit loss is recognized in net investment gains (losses) on investments in the condensed consolidated statements of (loss) income to the extent that the present value of expected cash flows is less than the amortized cost basis; any difference between fair value and the new amortized cost basis (net of the credit loss) is reflected in other comprehensive income , net of applicable income taxes. For equity securities, the Company evaluates its ability to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Evidence considered to determine anticipated recovery are analysts’ reports on the near-term prospects of the issuer and the financial condition of the issuer or the industry, in addition to the length and extent of the market value decline. If an OTTI is identified, the equity security is adjusted to fair value through a realized loss in earnings. There were no other-than-temporary impairments recorded for the three and six months ended June 30, 2019 and 2018 as a result of the OTTI analysis performed by management.

As of December 31, 2018 , we held 391 individual fixed income and equity securities that were in an unrealized loss position, of which 246 individual fixed income securities were in a continuous loss position for longer than 12 months. We did not recognize the unrealized losses in earnings on these fixed income securities for the three and six months ended June 30, 2019 or for the year ended December 31, 2018 . The Company expects to monitor liquidity needs and assess the sale of fixed income assets, if required, on a regular basis.

Atlas accounts for these limited partnership investments using the equity method of accounting. The carrying values of the equity method limited partnerships were $21.9 million and $24.0 million as of June 30, 2019 and December 31, 2018 , respectively. The carrying value of these investments is Atlas’ share of the net book value for each limited partnership. The carrying values of the collateral loans were $93,000 and $1.0 million as of June 30, 2019 and December 31, 2018 , respectively. Equity Method Investments by Type ($ in ‘000s) Unfunded Commitments Carrying Value June 30, 2019 June 30, 2019 December 31, 2018 Real estate $ 2,887 $ 10,839 $ 11,085 Insurance linked securities — 4,047 6,694 Activist hedge funds — 4,239 3,911 Venture capital 2,670 2,441 2,015 Other joint venture — 325 325 Total equity method investments $ 5,557 $ 21,891 $ 24,030 Due to the timing of financial information of the Company’s equity method investments, certain investments are recorded on a financial reporting lag of one to three months. The Company recognizes an impairment loss for equity method limited partnerships when evidence demonstrates that the loss is other-than-temporary. To determine if an other-than-temporary impairment has occurred, the Company evaluates whether or not the investee could sustain a level of earnings that would justify the carrying amount of the investment. Collateral loans are considered impaired when it is probable that the Company will not collect the contractual principal and interest. Valuation allowances are established for impaired loans equal to the fair value of the collateral less costs to sell or the present value of the loan’s expected future repayment cash flows discounted at the loan’s original effective interest rate. Valuation allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell or the present value of the loan’s expected future repayment cash flows. As of June 30, 2019 and December 31, 2018 , the Company had no valuation allowances established for impaired equity method limited partnerships and loans. Short-Term Investments Atlas’ short-term investments are comprised of fixed income securities. As of June 30, 2019 and December 31, 2018 , short-term investments totaled $15.4 million and $4.7 million , respectively. Collateral Pledged As of June 30, 2019 and December 31, 2018 , bonds, cash and cash equivalents with a fair value of $15.4 million and $14.9 million , respectively, were on deposit with state and provincial regulatory authorities. Also, from time to time, the Company pledges securities to and deposits cash with third parties to collateralize liabilities incurred under its policies of reinsurance assumed and other commitments made by the Company. As of June 30, 2019 and December 31, 2018 , the amounts of such pledged securities were $50.5 million and $31.3 million , respectively. Collateral pledging transactions are conducted under terms that are common and customary to standard collateral pledging and are subject to the Company’s standard risk management controls. These assets and investment income related thereto remain the property of the Company while pledged. Neither the state and/or provincial regulatory authorities nor any other third party has the right to re-pledge or sell said securities held on deposit.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments U.S. GAAP requires certain assets and liabilities to be reported at fair value in the financial statements and provides a framework for establishing that fair value. Level 1 inputs are given the highest priority in the hierarchy, while Level 3 inputs are given the lowest priority. Assets and liabilities carried at fair value are classified in one of the following three categories based on the nature of the inputs to the valuation technique used: Level 1 Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3 Unobservable inputs that are not corroborated by market data. These inputs reflect management’s best estimate of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Atlas’ assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the placement of the asset or liability within the fair value hierarchy levels. The following is a summary of significant valuation techniques for assets measured at fair value on a recurring basis: Level 1 U.S. treasury and other U.S. government obligations Comprised of certain U.S. Treasury fixed income securities. Valuation is based on unadjusted quoted prices for identical assets in active markets that Atlas can access. Equities Comprised of publicly-traded common stocks. Valuation is based on unadjusted quoted prices for identical assets in active markets that Atlas can access. Level 2 States, municipalities and political subdivisions Comprised of U.S. States, Territories and Possessions, U.S. Political Subdivisions of States, Territories and Possessions, U.S. Special Revenue and Special Assessment Obligations. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads. Corporate bonds Comprised of investment-grade fixed income securities. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields and credit spreads. Mortgage-backed and other asset-backed Comprised of securities that are collateralized by mortgage obligations and other assets. The primary inputs to the valuation include quoted prices for identical assets in inactive markets or similar assets in active or inactive markets, contractual cash flows, benchmark yields, collateral performance and credit spreads.

Atlas then reviews these valuations to ensure that the values are accurately recorded and that the data inputs and valuation techniques utilized are appropriate, consistently applied, and that the assumptions are reasonable and consistent with the objective of determining fair value. Though Atlas believes the valuation methods used in determining fair value are appropriate, different methodologies or assumptions could result in a different fair value as of June 30, 2019 . Management does not believe that reasonable changes to the inputs to its valuation methodology would result in a significantly higher or lower fair value measurement. The Company had no fair value investments classified as Level 3 as of June 30, 2019 or December 31, 2018 . There were no transfers in or out of Level 2 or Level 3 during the three and six months ended June 30, 2019 and 2018 .

The Insurance Subsidiaries’ prior parent retained those tax assets previously attributed to the Insurance Subsidiaries, which could not be utilized by Atlas as a result of this limitation. As a result, Atlas’ ability to recognize future tax benefits associated with a portion of its deferred tax assets generated during prior years has been permanently limited to the amount determined under IRC Section 382. The result is a maximum expected net deferred tax asset that Atlas has available after the merger, which is believed more likely than not to be utilized in the future, after consideration of the valuation allowance. On July 22, 2013, due to shareholder activity, a “triggering event” as determined under IRC Section 382 occurred. As a result, under IRC Section 382, the use of the Company’s net operating loss and other carryforwards generated prior to the “triggering event” will be limited as a result of this “ownership change” for tax purposes, which is defined as a cumulative change of more than 50% during any three-year period by shareholders owning 5% or greater portions of the Company’s shares. Due to this triggering event, the Company estimates that it will retain total tax effected federal net operating loss carryforwards (“NOLs”) of approximately $26.6 million as of June 30, 2019 .

Deferred tax assets are recognized to the extent that it is probable that future taxable income will be available against which they can be utilized. When considering the extent of the valuation allowance on Atlas’ deferred tax assets, weight is given by management to both positive and negative evidence. U.S. GAAP states that a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome in determining that a valuation allowance is not needed against deferred tax assets. Based on Atlas’ cumulative loss in recent years, Atlas has recorded a valuation allowance of $29.4 million and $29.4 million for its gross future deferred tax assets as of June 30, 2019 and December 31, 2018 , respectively. Atlas accounts for uncertain tax positions in accordance with the income taxes accounting guidance. Atlas has analyzed filing positions in the federal and state jurisdictions where it is required to file tax returns, as well as the open tax years in these jurisdictions. Atlas believes that its federal and state income tax filing positions and deductions will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial position. Therefore, no reserves for uncertain federal and state income tax positions have been recorded. Atlas would recognize interest and penalties related to unrecognized tax benefits as a component of the provision for federal income taxes. Atlas did not incur any federal income tax related interest income, interest expense or penalties for the three and six months ended June 30, 2019 and 2018 . Tax year 2015 and years thereafter are subject to examination by the Internal Revenue Service (“IRS”).

Commitments and Contingencies	Commitments and Contingencies The Company has entered into subscription agreements to allow for participation by the Company in limited liability investments, which invest in income-producing real estate, equities and insurance linked securities. As of June 30, 2019 , the unfunded commitments are $5.6 million . In the ordinary course of its business, Atlas is involved in legal proceedings, including lawsuits, regulatory examinations and inquiries. See “Explanatory Note” and “Part I, Item 2, 2019 Developments” for certain developments with respect to the Company and the Insurance Subsidiaries during the second quarter and subsequent to June 30, 2019 and see also “Part II, Item 1, Legal Proceedings”. Atlas is exposed to credit risk on balances receivable from policyholders, agents and reinsurers. Credit exposure to any one individual policyholder is not material. The Company’s policies, however, are distributed by agents who may manage cash collection on its behalf pursuant to the terms of their agency agreement. Atlas has procedures to monitor and minimize its exposure to delinquent agent balances, including, but not limited to, reviewing account current statements, processing policy cancellations for non-payment and other collection efforts deemed appropriate. Atlas also has procedures to evaluate the financial condition of its reinsurers and monitors concentrations of credit risk arising from similar geographic regions, activities, or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurers’ insolvency. Virtually all states require insurers licensed to do business therein to bear a portion of contingent and incurred claims handling expenses and the unfunded amount of “covered” claims and unearned premium obligations of impaired or insolvent insurance companies, either up to the policy’s limit, the applicable guaranty fund covered claims obligation cap, or 100% of statutorily defined workers’ compensation benefits, subject to applicable deductibles. These obligations are funded by assessments, made on a retrospective, prospective or pre-funded basis, which are levied by guaranty associations within the state, up to prescribed limits (typically 2% of “net direct premiums written”), on all member insurers in the state on the basis of the proportionate share of the premiums written by member insurers in certain covered lines of business in which the impaired, insolvent or failed insurer was engaged. In addition, as a condition to the ability to conduct business in certain states (and within the jurisdiction of some local governments), insurance companies are subject to or required to participate in various premium or claims based insurance-related assessments, including non-voluntary assigned risk pools, underwriting associations, workers’ compensation second-injury funds, reinsurance funds and other state insurance facilities. Atlas’ proportionate share of these various premium or claims based insurance-related assessments, including non-voluntary assigned risk pools, underwriting associations, workers’ compensation second-injury funds, reinsurance funds and other state insurance facilities is not expected to be material.

Underwriting Policy and Reinsurance Ceded [Abstract]
Reinsurance Ceded	Reinsurance Ceded As is customary in the insurance industry, Atlas reinsures portions of certain insurance policies it writes, thereby providing a greater diversification of risk and minimizing exposure on larger risks. Atlas remains contingently at risk with respect to any reinsurance ceded and would incur an additional loss if an assuming company were unable to meet its obligation under the reinsurance treaty. Atlas monitors the financial condition of its reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. Letters of credit are maintained for any unauthorized reinsurer to cover ceded unearned premium reserves, ceded claims and claims adjustment expense reserve balances and ceded paid claims. These policies mitigate the risk of credit quality or dispute from becoming a danger to financial strength. To date, the Company has not experienced any material difficulties in collecting reinsurance recoverables.

The process of determining the provision necessarily involves risks that the actual results may deviate, perhaps substantially, from the best estimates made. The incurred related to prior years for the three and six months ended June 30, 2019 and 2018 primarily resulted from unfavorable development on involuntary assigned risk pools and run-off commercial auto. Assigned risk pools are established by state governments to cover high-risk insureds who cannot purchase insurance through conventional means.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation On January 6, 2011, Atlas adopted a stock option plan (“Stock Option Plan”) in order to advance the interests of Atlas by providing incentives to eligible persons defined in the plan. In the second quarter of 2013, a new equity incentive plan (“Equity Incentive Plan”) was approved by the Company’s common shareholders at the Annual General Meeting, and Atlas ceased to grant new stock options under the preceding Stock Option Plan. The Equity Incentive Plan is a securities based compensation plan, pursuant to which Atlas may issue restricted stock grants for ordinary voting common shares, restricted stock, stock grants for ordinary voting common shares, stock options and other forms of equity incentives to eligible persons as part of their compensation. The Equity Incentive Plan is considered an amendment and restatement of the Stock Option Plan, although outstanding stock options issued pursuant to the Stock Option Plan will continue to be governed by the terms of the Stock Option Plan. Stock Options Stock Option Activity (prices in Canadian dollars designated with “C$” and U.S. dollars designated with “US$” Six months ended June 30, 2019 2018 Number of Options Weighted Average Exercise Price Number of Options Weighted Average Exercise Price C$ Denominated: Outstanding, beginning of period 27,195 C$6.00 54,390 C$6.00 Granted — — — — Exercised — — (27,195 ) C$6.00 Outstanding, end of period 27,195 C$6.00 27,195 C$6.00 US$ Denominated: Outstanding, beginning of period 375,000 US$17.01 375,000 US$17.01 Granted — — — — Exercised — — — — Outstanding, end of period 375,000 US$17.01 375,000 US$17.01 There are no stock options that are exercisable as of June 30, 2019 . The stock option grants outstanding have a weighted average remaining life of 4.98 years and have an intrinsic value of $0 as of June 30, 2019 . Under the Equity Incentive Plan, a director who either directly or indirectly purchases up to $100,000 of Atlas ordinary voting common stock on the open market, through the employee stock purchase plan, or via other means acceptable under this plan (see Note 13, ‘Other Employee Benefit Plans’) will receive a 3 to 1 matching grant of restricted stock grants for ordinary voting common shares (or for Canadian taxpayers, restricted stock units) based on the aggregate purchase price of ordinary voting common shares the director purchases during the 6 month period that began on June 18, 2013 and ended on December 31, 2013 , or for new directors within 6 months of their initial appointment date (the “Purchase Period”). Matching share grants of 148,152 restricted stock grants for ordinary voting common shares and 37,038 restricted stock units were made on February 28, 2014 (“Grant Date”). The number of ordinary voting common shares issued on the Grant Date were determined by dividing (A) the dollar amount of the Company matching contribution due based on purchases during the Purchase Period by (B) the closing common share price of one share of Company ordinary voting common stock at close of market on June 17, 2013 (“Closing Price”), which was $8.10 per share. The restricted stock grants for ordinary voting common shares will vest 20% on each anniversary of the Grant Date, subject to the terms of the Guidelines. The matching grant will be subject to all of the terms and conditions of the Equity Incentive Plan and applicable grant agreements. The matching grant award was discontinued during 2018 with no additional grants under the program since those discussed above. On December 31, 2018, the Company awarded restricted stock unit grants for ordinary voting common shares of the Company to its external directors pursuant to a director equity award agreement dated December 31, 2018. The awards, which were approved by the Company’s Board of Directors in March 2018, were valued at $40,000 per external director (“Aggregate Award”) and were made under the Company’s Equity Incentive Plan. The number of restricted stock units awarded was determined by dividing (A) the Aggregate Award by (B) the closing price of one share of Company ordinary voting common share at the close of market on April 4, 2018, which was $10.50 per share. For new directors, the Aggregate Award is proportionate to the director’s start date and priced as of that same day. During 2018, the Company awarded 17,524 RSU grants having an aggregate grant date fair value of $179,000 . The RSUs will vest 33.3% on January 1 of each year for the next three years. On March 12, 2015 , the Board of Directors of Atlas granted equity awards of (i) 200,000 restricted stock grants for ordinary voting common shares of the Company and (ii) 200,000 options to acquire ordinary voting common shares to the executive officers of the Company as part of the Company’s annual compensation process. The awards were made under the Company’s Equity Incentive Plan. The awards vest in five equal annual installments of 20% , provided that an installment shall not vest unless an annual performance target based on specific book value growth rates linked to return on equity goals is met. In the event the performance target is not met in any year, the 20% installment for such year shall not vest, but such non-vested installment shall carry forward and can become vested in future years (up to the fifth year from the date of grant), subject to achievement in a future year of the applicable performance target for such year. For the three and six months ended June 30, 2019 and 2018 , no shares of either of the restricted stock grants for ordinary voting common shares or the options to acquire ordinary voting common shares vested due to not meeting annual performance targets. The Monte-Carlo simulation model was used, for both the options and restricted stock grants for ordinary voting common shares, to estimate the fair value of compensation expense as a result of the performance based component of these grants. Utilizing the Monte-Carlo simulation model, the fair values were $1.5 million and $1.9 million for the options and restricted stock grants for ordinary voting common shares, respectively. This expense will be amortized over the anticipated vesting period.

In accordance with ASC 718 (Stock-Based Compensation), Atlas has recognized share-based compensation expense on a straight-line basis over the requisite service period of the last separately vesting portion of the award. Share-based compensation expense is a component of other underwriting expenses on the statements of income and comprehensive income. Atlas recognized $187,000 and $286,000 in share-based compensation expense, including income tax expense, for the three months ended June 30, 2019 and 2018 , respectively, and $497,000 and $571,000 for the six months ended June 30, 2019 and 2018 , respectively. As of June 30, 2019 , there was $346,000 of unrecognized total compensation expense related to restricted stock and restricted stock units for ordinary voting common shares. The expense will be amortized over a weighted average period of 11 months.

Other Employee Benefit Plans [Abstract]
Other Employee Benefit Plans	Other Employee Benefit Plans Defined Contribution Plan Atlas has a defined contribution 401(k) plan covering all qualified employees of Atlas and its subsidiaries. Contributions to this plan are limited based on IRS guidelines. Atlas matches 100% of the employee contribution up to 2.5% of annual earnings, plus 50% of additional contributions up to 2.5% of annual earnings, for a total maximum expense of 3.75% of annual earnings per participant. Atlas’ matching contributions are discretionary. Employees are 100% vested in their own contributions and vest in Atlas contributions based on years of service equally over 5 years with 100% vested after 5 years. Company contributions were $158,000 and $133,000 for the three months ended June 30, 2019 and 2018 , respectively, and $334,000 and $280,000 for the six months ended June 30, 2019 and 2018 , respectively. Employee Stock Purchase Plan The Atlas Employee Stock Purchase Plan (“ESPP”) encourages employee interest in the operation, growth and development of Atlas and provides an additional investment opportunity to employees. Full time and permanent part time employees working more than 30 hours per week are allowed to invest up to 7.5% of adjusted salary in Atlas ordinary voting common shares. Atlas matches 100% of the employee contribution up to 2.5% of annual earnings, plus 50% of additional contributions up to 5% of annual earnings, for a total maximum expense of 5% of annual earnings per participant. Atlas’ matching contributions are discretionary. Atlas also pays all administrative costs related to this plan. Atlas’ costs incurred related to the matching portion of the ESPP were $39,000 and $55,000 for the three months ended June 30, 2019 and 2018 , respectively, and $104,000 and $120,000 for the six months ended June 30, 2019 and 2018 , respectively.

These RSUs are participative and are included in the computations of earnings per common share and book value per common share for these periods. During the six months ended June 30, 2019 , the Company issued 5,842 ordinary voting common shares as a result of the vesting of RSUs. During the year ended December 31, 2018 , the Company issued 7,408 ordinary voting common shares as a result of the vesting of RSUs in addition to 27,195 ordinary voting common shares and immediately canceled 6,169 shares as a result of a cashless exercise of options. There were no options exercised during the six months ended June 30, 2019 . On March 21, 2017, the Company’s Board of Directors approved a Share Repurchase Program of up to 650,000 shares of common stock. The repurchases could be made from time to time in open market transactions, privately-negotiated transactions, block purchases, or otherwise in accordance with securities laws at the discretion of the Company’s management until March 21, 2018. The Share Repurchase Program was not extended. The Company’s decisions around the timing, volume, and nature of share repurchases, and the ultimate amount of shares repurchased, was dependent on market conditions, applicable securities laws, and other factors. The Share Repurchase Program and the Board’s authorization of the program could have been modified, suspended, or discontinued at any time. During 2018, 255,505 shares were repurchased under the Share Repurchase Program. Mezzanine Equity There were no preferred shares outstanding as of June 30, 2019 and December 31, 2018 .

Leases [Abstract]
Leases	Leases The Company adopted ASC 842 - Leases as of January 1, 2019, using the transition method wherein entities were allowed to initially apply the new lease standard at adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC 840 - Leases, and no retrospective adjustments were made to the comparative periods presented. Adoption of ASC 842 resulted in an increase of operating lease right-of-use assets (“ROU”) totaling approximately $2.6 million in other assets on the condensed consolidated statements of financial positions and operating lease liabilities of approximately $3.2 million and a decrease of net deferred rent liabilities of approximately $600,000 in other liabilities and accrued expenses on the condensed consolidated statements of financial position as of January 1, 2019. We currently lease real estate space, automobiles, and certain equipment under non-cancelable operating lease agreements. Leases with an initial term of 12 months or less, which are immaterial to the Company, are not recorded in the condensed consolidated statement of financial position. The Company has elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component, thus causing all fixed payments to be capitalized. The Company also elected the package of practical expedients permitted within the new standard, which among other things, allows the Company to carry forward historical lease classification. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as increases to lease payments based on changes in index rates or usage, are not recorded in the condensed consolidated statement of financial position. Certain agreements include an option to extend or renew the lease term at our option. The operating lease liability includes lease payments related to options to extend or renew the lease term if the Company is reasonably certain of exercising those options. Lease payments are discounted using the implicit discount rate in the lease. If the implicit discount rate for the lease cannot be readily determined, the Company uses an estimate of its incremental borrowing rate. AFH did not have any contracts accounted for as finance leases as of June 30, 2019 or January 1, 2019.

Debt Disclosure [Abstract]
Notes Payable	Notes Payable On April 26, 2017, Atlas issued $25 million of five -year 6.625% senior unsecured notes and received net proceeds of approximately $23.9 million after deducting underwriting discounts and commissions and other estimated offering expenses. Interest on the senior unsecured notes is payable quarterly on each January 26, April 26, July 26 and October 26. Atlas may, at its option, beginning with the interest payment date of April 26, 2020, and on any scheduled interest payment date thereafter, redeem the senior unsecured notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest to, but excluding, the date of redemption. The senior unsecured notes will rank senior in right of payment to any of Atlas’ existing and future indebtedness that is by its terms expressly subordinated or junior in right of payment to the senior unsecured notes. The senior unsecured notes will rank equally in right of payment to all of Atlas’ existing and future senior indebtedness, but will be effectively subordinated to any secured indebtedness to the extent of the value of the collateral securing such secured indebtedness. In addition, the senior unsecured notes will be structurally subordinated to the indebtedness and other obligations of Atlas’ subsidiaries.

Statutory Information [Abstract]
Statutory Information	Statutory Information As a holding company, Atlas could derive cash from its Insurance Subsidiaries generally in the form of dividends to meet its obligations, which will primarily consist of operating expense payments and debt payments. Atlas’ Insurance Subsidiaries fund their obligations primarily through premium and investment income and maturities in the securities portfolio. The Insurance Subsidiaries require regulatory approval for the return of capital, loans or advances, and, in certain circumstances, prior to the payment of dividends. In the event that dividends available to the holding company are inadequate to cover its operating expenses and debt payments, the holding company would need to raise capital, sell assets or incur future debt. The Insurance Subsidiaries must each maintain a minimum statutory capital and surplus of $1.5 million , $2.4 million and $3.5 million under the provisions of the Illinois Insurance Code, the Missouri Insurance Code and the New York Insurance Code, respectively. Dividends may only be paid from statutory unassigned surplus, and payments may not be made if such surplus is less than a stipulated amount. The dividend restriction for the ASI Pool Companies is the greater of statutory net income or 10% of total statutory capital and surplus. The dividend restriction for Global Liberty is the lower of 10% of statutory surplus or 100% of adjusted net investment income for the preceding twelve months. See “Explanatory Note” and “Part I, Item 2, 2019 Developments” for certain developments with respect to the Company and the Insurance Subsidiaries during the second quarter and subsequent to June 30, 2019 . Statutory Net Loss and Surplus of Atlas’ Insurance Subsidiaries ($ in ‘000s) June 30, 2019 December 31, 2018 Net income (loss) computed under statutory-basis accounting $ 3,946 $ (49,648 ) Combined statutory capital and surplus $ 2,425 $ 14,377 Atlas did not declare or pay any dividends to its common shareholders during the six months ended June 30, 2019 or during the year ended December 31, 2018 .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Throughout 2019, the Company has been exploring strategic alternatives, including, but not limited to, further strengthening its processes, reviewing its capital allocation and opportunities, a potential sale of the Company or certain assets, and balance sheet strengthening options with the goal of facilitating shareholder value generation. Atlas concluded that the utilization of its wholly owned managing general agency (“MGA”) operation to work with strategic external insurance and reinsurance partners will enable the Company to leverage its focus, experience and infrastructure to create value for stakeholders. The Company is working on additional arrangements with the objective of establishing MGA relationships in connection with the Company’s other lines of business as well. The Company agreed that should it choose to sell its MGA operations, 49% of the proceeds from any future sale of AGMI would be provided to the ASI Pool Companies to facilitate the rehabilitation process. There can be no assurance that any portion of the proceeds allocated to the ASI Pool Companies would be available for distribution to the Company. During 2019, the Illinois Department of Insurance (the “Department”) placed all three of the ASI Pool Companies (after Gateway was redomesticated in Illinois) into rehabilitation with the Director of the Department as the statutory rehabilitator. While in rehabilitation, the operations of such insurance subsidiaries will be overseen by the statutory rehabilitator although Atlas continues to maintain its legal ownership of the stock of the ASI Pool Companies. Management’s overriding strategic plan continues to include a transition of business from these insurance companies to alternative markets within a reasonable period of time utilizing the existing platform of the MGA to work with strategic external insurance and reinsurance partners. Effective August 15, 2019, no new business was written by the ASI Pool Companies, and only New York area new business was written by Global Liberty, which is focusing its resources on New York area business to leverage the subsidiary’s heritage in this large and specific market. The ASI Pool Companies and Global Liberty continued to write renewal business that met their underwriting standards during 2019. Non-renewals related to ASI Pool Companies’ insurance policies began towards the end of 2019. On January 22, 2020, the Company announced a non-binding letter of intent with Buckle, a technology-driven financial services company, to purchase the stock of Atlas’ indirect subsidiary Gateway and its corporate charter and forty-seven (47) state insurance licenses as well as state statutory deposits, subject to regulatory and other necessary approvals, for $4.7 million plus the value of all purchased deposits, such amount to be paid to the statutory rehabilitator for the benefit of the rehabilitation estate of Gateway, with a tentative closing date in April of 2020. The Company anticipates that Buckle will engage the MGA and certain other subsidiaries of the Company to provide services to Buckle and that Buckle will lease space at the Company’s headquarters and its Melville, NY office. The transaction will be subject to court approval and a bid process established by the statutory rehabilitator and approved by the court, and there can be no assurance that the transaction will be consummated on the terms described herein or at all.

Nature of Operations and Basi_2

Nature of Operations and Basis of Presentation (Policies)	6 Months Ended
	Jun. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation These statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Atlas and the entities it controls. All significant intercompany accounts and transactions have been eliminated. The results for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the full calendar year. The accompanying unaudited condensed consolidated financial statements, in accordance with Securities and Exchange Commission (“SEC”) rules for interim periods, do not include all of the information and notes required by U.S. GAAP for complete financial statements and should be read in conjunction with Atlas’ Annual Report on Form 10-K for the year ended December 31, 2018 , which provides a more complete understanding of the Company’s accounting policies, financial position, operating results, business properties, and other matters. Atlas has consistently applied the same accounting policies throughout all periods presented.
Estimates and Assumptions	Estimates and Assumptions The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and changes in estimates are recorded in the accounting period in which they are determined. The liability for unpaid claims and claims adjustment expenses and related amounts recoverable from reinsurers represent the most significant estimates in the accompanying condensed consolidated financial statements, and differences between such estimates and actual results could be material. Significant estimates in the accompanying financial statements also include the fair values of investments, deferred policy acquisition cost recoverability, and deferred tax asset valuation.
Segmentation	Operating Segments The Company operates in one business segment, the P&C insurance business.
New Accounting Standards	Recently Adopted Leases In March 2019, December 2018, July 2018 and February 2016, the FASB issued ASU 2019-01 Leases (Topic 842) Codification Improvements, ASU 2018-20 Leases (Topis 842) Narrow-Scope Improvements for Lessors, ASU 2018-11 Leases (Topic 842): Targeted Improvements and ASU 2018-10 Codification Improvements to Topic 842, Leases and ASU 2016-02, Leases (Topic 842), respectively. The provisions of these updates impact the classification criteria, disclosure requirements, and other specific transactions in lease accounting. The updates require either the use of a modified retrospective approach, which requires leases to be measured at the beginning of the earliest period presented, or the transition method, which requires entities to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted the updates on January 1, 2019 using the transition method with no change to comparative periods. See ‘Part I, Item 1, Note 16, Leases, for further discussion of the future lease commitments. The adoption of these updates resulted in the recognition of both a right-of-use asset and lease liability in the amounts of approximately $2.6 million and $3.2 million , respectively. There was no impact to any of Atlas’ current financial covenants as a result of the increase to reported liabilities. Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This guidance shortens the amortization period to the earliest call date for certain purchased callable debt securities held at a premium that have explicit, noncontingent call features and are callable at a fixed price and preset date. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. The Company adopted the update on January 1, 2019 with no impact on the Company’s consolidated financial statements because Atlas’ callable debt securities, that are held at a premium, are amortized to the earliest call date, which is consistent with current accounting treatment.
