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, 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 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. (“Anchor Management”), Plainview Premium Finance Company, Inc. (“Plainview Delaware”), Plainview Delaware’s wholly-owned subsidiary, Plainview Premium Finance Company of California, Inc. (“Plainview California” and together with Plainview Delaware, “Plainview”), UBI Holdings Inc. (“UBI Holdings”) and UBI Holdings’ wholly-owned subsidiary, DriveOn Digital IP Inc. (“DOIP” and together with UBI Holdings, “UBI”). The Insurance Subsidiaries distribute their insurance products through a network of retail independent agents. Together, the Insurance Subsidiaries are licensed to write property and casualty insurance in 49 states and the District of Columbia in the United States. Atlas’ core products are actively distributed in 42 of those states plus the District of Columbia. The Insurance Subsidiaries share common management and operating infrastructure. Atlas’ ordinary voting common shares are listed on the NASDAQ stock exchange 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. Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over operating and financial policies, are accounted for under the equity method unless we have elected the fair value option. All significant intercompany accounts and transactions have been eliminated. It is the opinion of management that these financial statements reflect all adjustments necessary for a fair statement of the interim results. The results for the three and six month periods ended June 30, 2018 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 accounting principles generally accepted in the United States of America for complete financial statements and should be read in conjunction with Atlas’ Annual Report on Form 10-K for the year ended December 31, 2017 , 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 represents the most significant estimate in the accompanying 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, deferred tax asset valuation and business combinations. Seasonality - The property and casualty (“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. Additionally, our New York “excess taxi program” has an annual renewal date in the third quarter. Net underwriting income is driven mainly by the timing and nature of claims, which can vary widely. Segmentation - The Company has one reportable business segment. Resources are allocated and management assesses financial performance based on this reportable segment.

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 month period ended June 30, 2018 , as compared to those described in our Annual Report on Form 10-K for the twelve month period ended December 31, 2017 , 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, 2018 have been adopted by the Company. Recently Adopted In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting . This update provides guidance on when an entity should apply modification accounting when changes are made to a share-based compensation award. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed prospective approach. The adoption of this ASU did not have an impact on the consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The provisions of this update modify the income tax consequences for intra-entity transactions not involving inventory. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed modified retrospective approach. Although Atlas has a number of fixed income securities that were transferred between companies owned by Atlas, this ASU did not affect the consolidated financial statements, because the transactions are between two U.S. entities that are part of the same consolidated group, the transactions were elected to be deferred for U.S. tax purposes until the items leave the group, which is consistent with the pre-tax GAAP treatment, and the Company already reports as part of its computational approach, the State tax results (which are zero) under the new ASU. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) . The provisions of this update address the diversity in practice of eight issues on the statement of cash flows. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed retrospective approach by restating all prior periods presented. Atlas’ presentation of its Condensed Consolidated Statements of Cash Flows did not change as a result of this ASU. Atlas elected the cumulative earnings approach for distributions from equity method investees upon adoption, which was consistent under prior GAAP treatment. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. One provision of this update requires that equity investments, except those accounted for under the equity method, be measured at fair value and changes in fair value recognized in net income. The provisions of this update are recognized as a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is not permitted, except for certain provisions. The Company adopted the update in the first quarter of 2018. The adoption of this ASU resulted in the recognition of $377 ,000 of net after-tax unrealized gains on equity investments as a cumulative-effect adjustment to increase retained earnings and decrease accumulated other comprehensive income (“AOCI”). The investment section of the Condensed Consolidated Statements of Financial Position has been modified from year end to reflect that equity securities are no longer classified as available-for-sale. Changes in the fair value of equity securities are recorded as income (loss) in the Condensed Consolidated Statements of Income and Comprehensive Income and as an adjustment to net income in the Condensed Consolidated Statements of Cash Flows. The FASB issued ASU 2014-09, ASU 2015-14, ASU 2016-10, ASU 2016-12, ASU 2016-20 and ASU 2017-05, Revenue from Contracts with Customers (Topic 606) . This update is a comprehensive revenue recognition standard that applies to all entities that have contracts with customers, except for those that fall within the scope of other standards, such as insurance contracts. Updates may be applied retrospectively to each period presented or retrospectively with the cumulative effect recognized at the date of initial application. The update is now effective for interim and annual reporting periods beginning after December 15, 2017. The Company adopted the update in the first quarter of 2018 with no impact on the consolidated financial statements. While these updates to Topic 606 are expected to have a significant impact on many companies, Atlas’ revenue is derived from transactions that do not fall within the scope of Topic 606, namely insurance contracts, investment income, and lease income. Not Yet Adopted In July 2018 and February 2016, the FASB issued 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 update requires 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. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date using the modified retrospective approach to restate beginning with the earliest period presented. See Note 8, ‘Commitments and Contingencies’ for further discussion of the future lease commitments. The adoption of this update is expected to increase both assets and liabilities, equally, on the Consolidated Statements of Financial Position by the present value of the leases at each reporting date. There is no expected impact to any of Atlas’ current financial covenants as a result of the increase to reported liabilities. 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 update shortens the amortization period for certain callable fixed income securities held at a premium to the earliest possible call date. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date using the prescribed modified retrospective approach. Atlas currently has fixed income securities that are callable and held at a premium. The amount of the difference in amortization from current accounting treatment to the change prescribed in this ASU will be recorded upon adoption as an adjustment to retained earnings and treated as a change in accounting principle. Because the first call date for most of these fixed income securities is less than one year from its maturity date, Atlas does not expect the adjustment to retained earnings to be material. The impact of the ASU on these certain securities will change as securities mature or are sold. Atlas also will consider the impact of this ASU on future purchases of fixed income securities. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) . The provisions of this update require an entity to broaden the information that it considers in developing its allowance for credit losses for assets. For public entities, this guidance is effective for years beginning after December 15, 2019, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date. Atlas does not currently have any investments with credit losses recorded or other significant credit allowances, therefore the provisions of this update are not expected to have a material impact on the consolidated financial statements upon adoption. Atlas will continue to monitor the investment portfolio and other financial instruments until adoption for any changes. All other recently issued pronouncements with effective dates after June 30, 2018 are not expected to have a material impact on the consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Earnings per ordinary voting common share, restricted voting common share, and participative restricted stock unit (“RSU”) (collectively, the “common shares”) for the three and six month periods ended June 30, 2018 and 2017 are as follows: Three Month Periods Ended Six Month Periods Ended ($ in ‘000s, except share and per share amounts) June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Basic: Income from operations before income taxes $ 7,079 $ 8,479 $ 13,891 $ 15,944 Income tax expense 1,503 2,969 2,786 5,582 Net income attributable to common shareholders $ 5,576 $ 5,510 $ 11,105 $ 10,362 Basic weighted average common shares outstanding 11,936,970 12,045,519 12,046,855 12,045,519 Earnings per common share basic $ 0.47 $ 0.46 $ 0.92 $ 0.86 Diluted: Basic weighted average common shares outstanding 11,936,970 12,045,519 12,046,855 12,045,519 Add: Dilutive stock options outstanding 15,296 136,361 23,488 146,127 Diluted weighted average common shares outstanding 11,952,266 12,181,880 12,070,343 12,191,646 Earnings per common share diluted $ 0.47 $ 0.45 $ 0.92 $ 0.85 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. 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 month periods ended June 30, 2018 and 2017 , all exercisable stock options were deemed to be dilutive.

Investments [Abstract]
Investments	INVESTMENTS Atlas adopted ASU 2016-01 as of January 1, 2018, which requires equity investments, except those accounted for under the equity method, to be measured at fair value and changes in fair value to be recognized in net income. Prior periods have not been restated for the current presentation, per the guidance in the ASU. See Note 2, ‘New Accounting Standards’, for a summary of the changes. The amortized cost, gross unrealized gains and losses and fair value for Atlas’ investments in fixed income securities are as follows ($ in ‘000s): As of June 30, 2018 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Fixed income securities: U.S. Treasury and other U.S. government obligations $ 20,975 $ 1 $ (528 ) $ 20,448 States, municipalities and political subdivisions 9,809 7 (248 ) 9,568 Corporate Banking/financial services 16,010 33 (446 ) 15,597 Consumer goods 11,576 — (310 ) 11,266 Capital goods 6,377 34 (171 ) 6,240 Energy 7,523 1 (255 ) 7,269 Telecommunications/utilities 9,135 — (379 ) 8,756 Health care 832 — (76 ) 756 Total corporate 51,453 68 (1,637 ) 49,884 Mortgage backed Mortgage backed - agency 26,653 6 (882 ) 25,777 Mortgage backed - commercial 22,675 74 (727 ) 22,022 Total mortgage backed 49,328 80 (1,609 ) 47,799 Other asset backed 10,535 6 (58 ) 10,483 Total fixed income securities $ 142,100 $ 162 $ (4,080 ) $ 138,182 As of December 31, 2017 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Fixed income securities: U.S. Treasury and other U.S. government obligations $ 21,488 $ — $ (302 ) $ 21,186 States, municipalities and political subdivisions 13,265 78 (100 ) 13,243 Corporate Banking/financial services 21,246 189 (53 ) 21,382 Consumer goods 9,674 70 (65 ) 9,679 Capital goods 7,822 181 (11 ) 7,992 Energy 7,460 81 (26 ) 7,515 Telecommunications/utilities 11,179 109 (73 ) 11,215 Health care 1,112 1 (54 ) 1,059 Total corporate 58,493 631 (282 ) 58,842 Mortgage backed Mortgage backed - agency 30,920 57 (364 ) 30,613 Mortgage backed - commercial 22,689 153 (255 ) 22,587 Total mortgage backed 53,609 210 (619 ) 53,200 Other asset backed 11,556 8 (51 ) 11,513 Total fixed income securities $ 158,411 $ 927 $ (1,354 ) $ 157,984 The following table summarizes the amortized cost and fair value of fixed income securities by contractual maturity ($ in ‘000s).

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. There were no other-than-temporary impairments recorded for the three and six month periods ended June 30, 2018 and 2017 as a result of the above analysis performed by management.

As of December 31, 2017 , we held 346 and 2 individual fixed income and equity securities, respectively, that were in an unrealized loss position, of which 103 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 month periods ended June 30, 2018 or for the year ended December 31, 2017 , because we neither intend to sell the securities nor do we believe that it is more likely than not that we will be required to sell these securities before recovery of their amortized costs. The following table summarizes the components of net investment income for the three and six month periods ended June 30, 2018 and 2017 ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Total investment income Interest income $ 1,069 $ 917 $ 2,133 $ 1,805 Income from other investments 284 573 467 1,049 Investment expenses (186 ) (224 ) (469 ) (445 ) Net investment income $ 1,167 $ 1,266 $ 2,131 $ 2,409 The following table presents the aggregate proceeds, gross realized investment gains and gross realized investment losses from sales and calls of fixed income securities, equities and other investments for the three and six month periods ended June 30, 2018 and 2017 ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Fixed income securities: Proceeds from sales and calls $ 15,402 $ 9,130 $ 36,357 $ 14,352 Gross realized investment gains 85 110 253 164 Gross realized investment losses (236 ) (22 ) (457 ) (32 ) Equities: Proceeds from sales $ 3,000 $ 3,128 $ 4,849 $ 4,582 Gross realized investment gains 290 196 636 288 Gross realized investment losses (26 ) — (26 ) (2 ) Other Investments: Proceeds from sales $ 41 $ — $ 41 $ — Gross realized investment gains 41 — 41 — Total: Proceeds from sales and calls $ 18,443 $ 12,258 $ 41,247 $ 18,934 Gross realized investment gains 416 306 930 452 Gross realized investment losses (262 ) (22 ) (483 ) (34 ) The following table summarizes the components of net realized gains (losses) for the three and six month periods ended June 30, 2018 and 2017 ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Fixed income securities $ (151 ) $ 88 $ (204 ) $ 132 Equities 264 196 610 286 Other 41 — 41 — Net realized gains $ 154 $ 284 $ 447 $ 418 Other Investments Atlas’ other investments are comprised of collateral loans and various limited partnerships that invest in income-producing real estate, equities, or insurance linked securities. Atlas accounts for these limited partnership investments using the equity method of accounting. The carrying values of the equity method limited partnerships were $26.4 million and $25.3 million as of June 30, 2018 and December 31, 2017 , 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 $2.7 million and $6.2 million as of June 30, 2018 and December 31, 2017 , respectively. 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, 2018 and December 31, 2017 , the Company had no valuation allowances established for impaired loans. Collateral pledged As of June 30, 2018 and December 31, 2017 , bonds, cash and cash equivalents with a fair value of $14.8 million and $15.0 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, 2018 and December 31, 2017 , the amounts of such pledged securities were $23.2 million and $12.2 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 Equities: Comprised of publicly-traded common stocks. Valuation is based on unadjusted quoted prices for identical assets in active markets that Atlas can access. Fixed Income: 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. 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. The following table summarizes Atlas’ investments at fair value as of June 30, 2018 and as of December 31, 2017 ($ in ‘000s): As of June 30, 2018 Level 1 Level 2 Level 3 Total Fixed income securities: U.S. Treasury and other U.S. government obligations $ 20,448 $ — $ — $ 20,448 States, municipalities and political subdivisions — 9,568 — 9,568 Corporate Banking/financial services — 15,597 — 15,597 Consumer goods — 11,266 — 11,266 Capital goods — 6,240 — 6,240 Energy — 7,269 — 7,269 Telecommunications/utilities — 8,756 — 8,756 Health care — 756 — 756 Total corporate — 49,884 — 49,884 Mortgage backed Mortgage backed - agency — 25,777 — 25,777 Mortgage backed - commercial — 22,022 — 22,022 Total mortgage backed — 47,799 — 47,799 Other asset backed — 10,483 — 10,483 Total fixed income securities $ 20,448 $ 117,734 $ — $ 138,182 Equities 6,463 — — 6,463 Totals $ 26,911 $ 117,734 $ — $ 144,645 As of December 31, 2017 Level 1 Level 2 Level 3 Total Fixed income securities: U.S. Treasury and other U.S. government obligations $ 21,186 $ — $ — $ 21,186 States, municipalities and political subdivisions — 13,243 — 13,243 Corporate Banking/financial services — 21,382 — 21,382 Consumer goods — 9,679 — 9,679 Capital goods — 7,992 — 7,992 Energy — 7,515 — 7,515 Telecommunications/utilities — 11,215 — 11,215 Health care — 1,059 — 1,059 Total corporate — 58,842 — 58,842 Mortgage backed Mortgage backed - agency — 30,613 — 30,613 Mortgage backed - commercial — 22,587 — 22,587 Total mortgage backed — 53,200 — 53,200 Other asset backed — 11,513 — 11,513 Total fixed income securities $ 21,186 $ 136,798 $ — $ 157,984 Equities 8,446 — — 8,446 Totals $ 29,632 $ 136,798 $ — $ 166,430 Atlas primarily uses the services of external securities pricing vendors to obtain these values. 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, 2018 . 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, 2018 or December 31, 2017 . There were no transfers in or out of Level 2 or Level 3 during the three and six month periods ended June 30, 2018 and 2017 .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. Among other things, beginning with the 2018 tax year, the Tax Act reduced the Company’s corporate federal tax rate from a marginal rate of 35% to a flat 21%, eliminated the corporate Alternative Minimum Tax (“AMT”), changed reserving and other aspects of the computation of taxable income for insurance companies, and modified the net operating loss carryback and carryforward provisions for all entities in the group except for those subject to tax as property and casualty companies. The modified net operating loss provisions no longer allow a carryback to prior years to recover past taxes, but now allow an indefinite carryforward period subject to a yearly utilization limit. As discussed above, any net operating losses with respect to the insurance entities taxed as property and casualty companies retain the current net operating loss carryback and carryover provisions, which are two years carryback and 20 years carryforward. As of December 31, 2016, the Company measured its deferred tax items at the enacted rate in effect of 35%. Due to the Tax Act’s enactment, the Company’s deferred tax assets and liabilities as of December 31, 2017 have been re-measured at the new enacted tax rate of 21%. For the year ended December 31, 2017, the Company recognized income tax expense of $10.5 million related to reduction in the net deferred tax asset as a result of this re-measurement. Atlas’ effective tax rate was 21.3% and 20.1% for the three and six month periods ended June 30, 2018 , respectively, and 35.0% for each of the three and six month periods ended June 30, 2017 . The table below reconciles the U.S. statutory marginal income tax rate to the effective tax rate ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Amount % Amount % Amount % Amount % Provision for taxes at U.S. statutory marginal income tax rate $ 1,487 21.0 % $ 2,968 35.0 % $ 2,917 21.0 % $ 5,581 35.0 % Nondeductible expenses 19 0.3 6 0.1 28 0.2 27 0.2 Tax-exempt income (3 ) — (5 ) (0.1 ) (6 ) — (10 ) (0.1 ) State tax (net of federal benefit) — — — — (2 ) — (2 ) — Stock compensation — — — — (42 ) (0.3 ) (13 ) (0.1 ) Nondeductible acquisition accounting adjustment — — — — (109 ) (0.8 ) — — Other — — — — — — (1 ) — Provision for income taxes for continuing operations $ 1,503 21.3 % $ 2,969 35.0 % $ 2,786 20.1 % $ 5,582 35.0 % Income tax expense consists of the following for the three and six month periods ended June 30, 2018 and 2017 ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Current tax (benefit) expense $ (147 ) $ 2,304 $ (296 ) $ 4,707 Deferred tax expense 1,650 665 3,082 875 Total $ 1,503 $ 2,969 $ 2,786 $ 5,582 Upon the transaction forming Atlas on December 31, 2010, a yearly limitation as required by U.S. Internal Revenue Code of 1986 (as amended, “IRC”) Section 382 that applies to changes in ownership on the future utilization of Atlas’ net operating loss carryforwards was calculated. 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 of approximately $11.5 million as of June 30, 2018 . The components of net deferred income tax assets and liabilities as of June 30, 2018 and December 31, 2017 are as follows ($ in ‘000s): June 30, 2018 December 31, 2017 Gross deferred tax assets: Losses carried forward $ 11,477 $ 13,313 Claims liabilities and unearned premium reserves 6,261 6,171 Tax credits 879 1,172 Investments 661 — Commissions 887 623 Stock compensation 627 602 Other 892 1,094 Total gross deferred tax assets 21,684 22,975 Gross deferred tax liabilities: Deferred policy acquisition costs 2,931 3,107 Investments — 213 Fixed assets 1,764 847 Intangible assets 674 715 Other 1,679 1,108 Total gross deferred tax liabilities 7,048 5,990 Net deferred tax assets $ 14,636 $ 16,985 Amounts and expiration dates of the operating loss carryforwards as of June 30, 2018 are as follows ($ in ‘000s): Year of Occurrence Year of Expiration Amount 2001 2021 $ 135 2002 2022 4,317 2006 2026 7,825 2007 2027 5,131 2008 2028 1,949 2009 2029 1,949 2010 2030 1,949 2011 2031 294 2012 2032 9,235 2015 2035 1 2017 2037 21,865 Total $ 54,650 NOLs and other carryforwards generated in 2015 and 2017 are not limited by IRC Section 382. Atlas has not established a valuation allowance for its gross future deferred tax assets as of June 30, 2018 or December 31, 2017 . Based on Atlas’ expectations of future taxable income, its ability to change its investment strategy, as well as reversing gross future tax liabilities, management believes it is more likely than not that Atlas will fully realize the net future tax assets. However, there can be no guarantee that a valuation allowance will not be required in the future. 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 month periods ended June 30, 2018 and 2017 . Tax year 2014 and years thereafter are subject to examination by the IRS.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES On May 22, 2012, Atlas closed the sale and leaseback of its former headquarters building to 150 Northwest Point, LLC, a Delaware limited liability company. Atlas recognized a gain on the sale of this property of $213,000 , which was deferred and recognized over the initial five year lease term, which ended in May 2017. The deferred gain was completely recognized at the end of the second quarter in 2017, and no offset to rent expense was recognized for the three and six month periods ended June 30, 2018 . Atlas recognized $6,000 and $17,000 as an offset to rent expense for the three and six month periods ended June 30, 2017 , respectively. Total rental expense recognized on the former headquarters building was $201,000 and $398,000 for the three and six month periods ended June 30, 2017 , respectively. There was no rental expense recognized on the former headquarters building for the three and six month periods ended June 30, 2018 . As of June 30, 2018 , Atlas has the following future minimum rentals, related principally to office space, required under operating leases having initial or remaining non-cancelable lease terms in excess of one year ($ in ‘000s): Year 2018 2019 2020 2021 2022 2023 & Beyond Total Amount $ 568 $ 1,153 $ 1,087 $ 954 $ 174 $ 16 $ 3,952 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, 2018 , the unfunded commitments are $6.1 million . In the ordinary course of its business, Atlas is involved in legal proceedings, including lawsuits, regulatory examinations and inquiries. 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.

Atlas’ Chicago area staff moved into this space in late October 2017 and occupies approximately 70,000 square feet of the building. An unrelated tenant occupies the remaining office space in the building. Rental income related to this lease agreement was $16,000 and $103,000 for the three month periods ended June 30, 2018 and 2017 , respectively, and $179,000 and $207,000 for the six month periods ended June 30, 2018 and 2017 , respectively.

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. Premiums written, premiums earned and amounts related to reinsurance as of and for the three and six month periods ended June 30, 2018 and 2017 are as follows ($ in ‘000s): Three Month Periods Ended Six Month Periods Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Direct premiums written $ 51,138 $ 56,409 $ 136,848 $ 147,474 Assumed premiums written 6,221 945 16,100 8,376 Ceded premiums written (22,594 ) (11,042 ) (35,997 ) (23,905 ) Net premiums written $ 34,765 $ 46,312 $ 116,951 $ 131,945 Direct premiums earned $ 63,854 $ 63,474 $ 126,978 $ 121,839 Assumed premiums earned 4,879 2,254 8,935 3,911 Ceded premiums earned (13,374 ) (11,679 ) (24,662 ) (23,275 ) Net premiums earned $ 55,359 $ 54,049 $ 111,251 $ 102,475 Ceded claims and claims adjustment expenses $ 3,784 $ 3,109 $ 12,029 $ 6,834 Ceding commissions 3,531 3,085 7,994 6,785

The unfavorable development for the three and six month periods ended June 30, 2018 and 2017 primarily resulted from Atlas’ participation in non-voluntary 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 (the “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 (the “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 units, 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 for the six month periods ended June 30, 2018 and 2017 follows (prices in Canadian dollars designated with “C$” and United States dollars designated with “US$”): Six Month Periods Ended June 30, 2018 June 30, 2017 C$ Denominated: Number of Shares Average Exercise Price Number of Shares Average Exercise Price Outstanding, beginning of period 54,390 C$6.00 187,728 C$6.22 Granted — — — — Exercised (27,195 ) C$6.00 — — Outstanding, end of period 27,195 C$6.00 187,728 C$6.22 Six Month Periods Ended June 30, 2018 June 30, 2017 US$ Denominated: Number of Shares Average Exercise Price Number of Shares Average Exercise Price 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 202,195 stock options that are exercisable as of June 30, 2018 . The stock option grants outstanding have a weighted average remaining life of 5.98 years and have an intrinsic value of $114 ,000 as of June 30, 2018 . 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 six 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 (the “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 (the “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. 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 month periods ended June 30, 2018 , no shares of either of these restricted stock grants for ordinary voting common shares or these options to acquire ordinary voting common shares vested due to not meeting annual performance targets. For the three and six month periods ended June 30, 2017 , 40,000 shares vested. 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. Restricted shares - The activity for the restricted stock grants for ordinary voting common shares and restricted share units for the six month periods ended June 30, 2018 and 2017 are as follows: Six Month Periods Ended June 30, 2018 June 30, 2017 Number of Shares Weighted Average Fair Value at Grant Date Number of Shares Weighted Average Fair Value at Grant Date Non-vested, beginning of period 234,080 $ 16.15 311,120 $ 15.92 Granted — — — — Vested (44,448 ) 12.20 (77,040 ) 15.21 Non-vested, end of period 189,632 $ 17.08 234,080 $ 16.15 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 $286,000 and $285,000 in share-based compensation expense, including income tax expense, for the three month periods ended June 30, 2018 and 2017 , respectively, and $571,000 and $605,000 for the six month periods ended June 30, 2018 and 2017 , respectively. Total unearned share-based compensation expense was $508,000 related to all stock option grants and $943,000 related to restricted stock grants for ordinary voting common shares and restricted share units as of June 30, 2018 . This unearned share-based compensation expense will be amortized over the next 20 months.

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 $133,000 and $114,000 for the three month periods ended June 30, 2018 and 2017 , respectively, and $280,000 and $242,000 for the six month periods ended June 30, 2018 and 2017 , respectively. Employee Stock Purchase Plan - The Atlas Employee Stock Purchase Plan (the “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 were 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 $55,000 and $50,000 for the three month periods ended June 30, 2018 and 2017 , respectively, and $120,000 and $105,000 for the six month periods ended June 30, 2018 and 2017 , respectively.

(including its subsidiaries and affiliated companies, “Kingsway”) were sold to non-affiliates of Kingsway. The restricted voting common shares are entitled to vote at all meetings of shareholders, except at meetings of holders of a specific class that are entitled to vote separately as a class. The restricted voting common shares as a class shall not carry more than 30% of the aggregate votes eligible to be voted at a general meeting of common shareholders. The Kingsway-owned restricted voting common shares automatically converted to ordinary voting common shares upon their sale to non-affiliates of Kingsway. There are no restricted voting common shares outstanding as of June 30, 2018 . There were 7,408 and 14,816 non-vested restricted stock units (“RSUs”) as of June 30, 2018 and December 31, 2017 , 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. In each of the six month periods ended June 30, 2018 and 2017 , the Company issued 7,408 ordinary voting common shares as a result of the vesting of RSUs. During the six month period ended June 30, 2018 , the Company issued 27,195 ordinary voting common shares and immediately canceled 6,169 shares as a result of a cashless exercise of options. 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 the six month period ended June 30, 2018 , 255,505 shares were repurchased under this Share Repurchase Program. Mezzanine Equity There were no preferred shares outstanding as of June 30, 2018 and December 31, 2017 . Preferred shareholders are entitled to dividends on a cumulative basis, whether or not declared by the Board of Directors, at the rate of $0.045 per share per year ( 4.5% ) and may be paid in cash or in additional preferred shares at the option of Atlas. In liquidation, dissolution or winding-up of Atlas, preferred shareholders receive the greater of $1.00 per share plus all declared and unpaid dividends or the amount they would receive in liquidation if the preferred shares had been converted to restricted voting common shares or ordinary voting common shares immediately prior to liquidation. Preferred shareholders are not entitled to vote. As of December 31, 2017 , Atlas accrued $333 ,000 in dividends on the preferred shares for the former owner of Anchor.

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. The senior unsecured notes were issued under an indenture and supplemental indenture that contain covenants that, among other things, limit: (i) the ability of Atlas to merge or consolidate, or lease, sell, assign or transfer all or substantially all of its assets; (ii) the ability of Atlas to sell or otherwise dispose of the equity securities of certain of its subsidiaries; (iii) the ability of certain of Atlas’ subsidiaries to issue equity securities; (iv) the ability of Atlas to permit certain of its subsidiaries to merge or consolidate, or lease, sell, assign or transfer all or substantially all of their respective assets; and (v) the ability of Atlas and its subsidiaries to incur debt secured by equity securities of certain of its subsidiaries. On March 9, 2015, American Insurance Acquisition, Inc. (“American Acquisition”), a wholly-owned direct subsidiary of Atlas, entered into a loan and security agreement (“Loan Agreement”) for a $35.0 million loan facility with Fifth Third Bank. On May 7, 2016, American Acquisition entered into a Modification of Loan Documents with Fifth Third Bank to amend its Loan Agreement. The Loan Agreement, as modified, included a $30.0 million line of credit (“Draw Amount”), which could have been drawn in increments at any time until December 31, 2016. The $30.0 million line of credit had a five year term and bore interest at one-month LIBOR plus 4.5% . The Loan Agreement also included a $5.0 million revolving line of credit (“Revolver”), which could have been drawn upon until May 7, 2018, that bore interest at one-month LIBOR plus 2.75% . The Loan Agreement was terminated in April 2017. Atlas used a portion of the net proceeds of the senior unsecured notes offering, together with cash on hand, for the repayment of all outstanding balances under the Draw Amount and Revolver, $15.5 million and $3.9 million , respectively. At December 31, 2016, American Acquisition was in compliance with the covenants of the Loan Agreement. In February 2017, American Acquisition filed its statutorily required financial statements for the year ended December 31, 2016, which are used to determine on-going compliance with the covenants contained in the Loan Agreement. As a result of the reserve strengthening and its effect on American Acquisition’s December 31, 2016 financial statements, American Acquisition was not in compliance with the Loan Agreements’ EBITDA Ratio covenant as of March 13, 2017. American Acquisition had a thirty day period to cure this covenant non-compliance, and the Company and American Acquisition agreed with the lender to a modification to the loan covenants to more specifically address the effects of reserve modifications and/or obtaining a waiver with respect to the existing non-compliance. Interest expense on notes payables was $461,000 and $640,000 for the three month periods ended June 30, 2018 and 2017 , respectively, and $916,000 and $915,000 for the six month periods ended June 30, 2018 and 2017 , respectively. Notes payable outstanding as of June 30, 2018 and December 31, 2017 ($ in ‘000s): June 30, 2018 December 31, 2017 6.625% Senior Unsecured Notes due April 26, 2022 $ 25,000 $ 25,000 Unamortized issuance costs (857 ) (969 ) Total notes payable $ 24,143 $ 24,031

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 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 Subsidiaries 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 month period. As of June 30, 2018 , our Insurance Subsidiaries had a combined statutory surplus of $89.2 million and had combined net premiums written and combined statutory net income for the six month period ended June 30, 2018 of $117.0 million and $15.5 million , respectively. As of December 31, 2017 , our Insurance Subsidiaries had a combined statutory surplus of $87.8 million and had combined net premiums written and combined statutory net loss for the twelve month period ended December 31, 2017 of $231.1 million and $35.2 million , respectively. Atlas did not declare or pay any dividends to its common shareholders during the six month period ended June 30, 2018 or during the year ended December 31, 2017 .

Nature of Operations and Basis of Presentation (Policies)	6 Months Ended
	Jun. 30, 2018
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. Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over operating and financial policies, are accounted for under the equity method unless we have elected the fair value option. All significant intercompany accounts and transactions have been eliminated. It is the opinion of management that these financial statements reflect all adjustments necessary for a fair statement of the interim results. The results for the three and six month periods ended June 30, 2018 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 accounting principles generally accepted in the United States of America for complete financial statements and should be read in conjunction with Atlas’ Annual Report on Form 10-K for the year ended December 31, 2017 , 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 represents the most significant estimate in the accompanying 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, deferred tax asset valuation and business combinations.
Segmentation	Segmentation - The Company has one reportable business segment. Resources are allocated and management assesses financial performance based on this reportable segment.
New Accounting Standards	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, 2018 have been adopted by the Company. Recently Adopted In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting . This update provides guidance on when an entity should apply modification accounting when changes are made to a share-based compensation award. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed prospective approach. The adoption of this ASU did not have an impact on the consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The provisions of this update modify the income tax consequences for intra-entity transactions not involving inventory. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed modified retrospective approach. Although Atlas has a number of fixed income securities that were transferred between companies owned by Atlas, this ASU did not affect the consolidated financial statements, because the transactions are between two U.S. entities that are part of the same consolidated group, the transactions were elected to be deferred for U.S. tax purposes until the items leave the group, which is consistent with the pre-tax GAAP treatment, and the Company already reports as part of its computational approach, the State tax results (which are zero) under the new ASU. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) . The provisions of this update address the diversity in practice of eight issues on the statement of cash flows. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted. The Company adopted the update in the first quarter of 2018 using the prescribed retrospective approach by restating all prior periods presented. Atlas’ presentation of its Condensed Consolidated Statements of Cash Flows did not change as a result of this ASU. Atlas elected the cumulative earnings approach for distributions from equity method investees upon adoption, which was consistent under prior GAAP treatment. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. One provision of this update requires that equity investments, except those accounted for under the equity method, be measured at fair value and changes in fair value recognized in net income. The provisions of this update are recognized as a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. For public entities, this guidance is effective for years beginning after December 15, 2017, including interim periods within those years. Early adoption is not permitted, except for certain provisions. The Company adopted the update in the first quarter of 2018. The adoption of this ASU resulted in the recognition of $377 ,000 of net after-tax unrealized gains on equity investments as a cumulative-effect adjustment to increase retained earnings and decrease accumulated other comprehensive income (“AOCI”). The investment section of the Condensed Consolidated Statements of Financial Position has been modified from year end to reflect that equity securities are no longer classified as available-for-sale. Changes in the fair value of equity securities are recorded as income (loss) in the Condensed Consolidated Statements of Income and Comprehensive Income and as an adjustment to net income in the Condensed Consolidated Statements of Cash Flows. The FASB issued ASU 2014-09, ASU 2015-14, ASU 2016-10, ASU 2016-12, ASU 2016-20 and ASU 2017-05, Revenue from Contracts with Customers (Topic 606) . This update is a comprehensive revenue recognition standard that applies to all entities that have contracts with customers, except for those that fall within the scope of other standards, such as insurance contracts. Updates may be applied retrospectively to each period presented or retrospectively with the cumulative effect recognized at the date of initial application. The update is now effective for interim and annual reporting periods beginning after December 15, 2017. The Company adopted the update in the first quarter of 2018 with no impact on the consolidated financial statements. While these updates to Topic 606 are expected to have a significant impact on many companies, Atlas’ revenue is derived from transactions that do not fall within the scope of Topic 606, namely insurance contracts, investment income, and lease income. Not Yet Adopted In July 2018 and February 2016, the FASB issued 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 update requires 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. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date using the modified retrospective approach to restate beginning with the earliest period presented. See Note 8, ‘Commitments and Contingencies’ for further discussion of the future lease commitments. The adoption of this update is expected to increase both assets and liabilities, equally, on the Consolidated Statements of Financial Position by the present value of the leases at each reporting date. There is no expected impact to any of Atlas’ current financial covenants as a result of the increase to reported liabilities. 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 update shortens the amortization period for certain callable fixed income securities held at a premium to the earliest possible call date. For public entities, this guidance is effective for years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date using the prescribed modified retrospective approach. Atlas currently has fixed income securities that are callable and held at a premium. The amount of the difference in amortization from current accounting treatment to the change prescribed in this ASU will be recorded upon adoption as an adjustment to retained earnings and treated as a change in accounting principle. Because the first call date for most of these fixed income securities is less than one year from its maturity date, Atlas does not expect the adjustment to retained earnings to be material. The impact of the ASU on these certain securities will change as securities mature or are sold. Atlas also will consider the impact of this ASU on future purchases of fixed income securities. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) . The provisions of this update require an entity to broaden the information that it considers in developing its allowance for credit losses for assets. For public entities, this guidance is effective for years beginning after December 15, 2019, including interim periods within those years. Early adoption is permitted. The Company plans on adopting the update on the required effective date. Atlas does not currently have any investments with credit losses recorded or other significant credit allowances, therefore the provisions of this update are not expected to have a material impact on the consolidated financial statements upon adoption. Atlas will continue to monitor the investment portfolio and other financial instruments until adoption for any changes. All other recently issued pronouncements with effective dates after June 30, 2018 are not expected to have a material impact on the consolidated financial statements.
