Basis of Presentation [Abstract]
Basis of Presentation	2. Basis of Presentation Our unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include our accounts and the accounts of our subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2021 included in our Annual Report on Form 10-K filed with the SEC. The interim financial data as of September 30, 2022 and 2021 is unaudited. However, in the opinion of management, the interim financial data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The results of operations for the periods ended September 30, 2022 are not necessarily indicative of the operating results to be expected for the full year. Subsequent Event On October 7, 2022 the Company consummated the sale of substantially all of its excess and surplus lines operations to Core Specialty Insurance Holdings, Inc. (“Core Specialty”), a specialty property and casualty insurer, for $40.0 million cash consideration, plus an estimated $19.2 million consideration for the acquisition costs associated with certain net unearned premium reserves. The transaction was comprised of all or portions of nine business units within the Company’s former Specialty Commercial Segment, certain related assets and liabilities, and the immediate transition to Core Specialty of approximately 200 employees who produce and support these lines of businesses. Core Specialty’s acquisition and assumption of the Company’s excess and surplus lines of business and the related assets and liabilities was made effective as of September 30, 2022. Use of Estimates in the Preparation of the Financial Statements Our preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect our reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting period. Refer to “Critical Accounting Estimates and Judgments” under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021 for information on accounting policies that we consider critical in preparing our consolidated financial statements. Actual results could differ materially from those estimates. Fair Value of Financial Instruments Fair value estimates are made at a point in time based on relevant market data as well as the best information available about the financial instruments. Fair value estimates for financial instruments for which no or limited observable market data is available are based on judgments regarding current economic conditions, credit and interest rate risk. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the instrument. In addition, changes in the underlying assumptions used in the fair value measurement technique, including discount rate and estimates of future cash flows, could significantly affect these fair value estimates. Cash and Cash Equivalents Restricted Cash Senior Unsecured Notes Due 2029 Subordinated Debt Securities For accounts receivable, reinsurance balances, premiums receivable, federal income tax recoverable and other assets, the carrying amounts are held at net realizable value which approximates fair value because of the short maturity of such financial instruments. Variable Interest Entities On June 21, 2005, we formed Hallmark Statutory Trust I (“Trust I”), an unconsolidated trust subsidiary, for the sole purpose of issuing $30.0 million in trust preferred securities. Trust I used the proceeds from the sale of these securities and our initial capital contribution to purchase $30.9 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust I, and the payments under the debt securities are the sole revenues of Trust I. On August 23, 2007, we formed Hallmark Statutory Trust II (“Trust II”), an unconsolidated trust subsidiary, for the sole purpose of issuing $25.0 million in trust preferred securities. Trust II used the proceeds from the sale of these securities and our initial capital contribution to purchase $25.8 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust II, and the payments under the debt securities are the sole revenues of Trust II. We evaluate on an ongoing basis our investments in Trust I and Trust II (collectively the “Trusts”) and have determined that we do not have a variable interest in the Trusts. Therefore, the Trusts are not included in our consolidated financial statements. Income Taxes We file a consolidated federal income tax return. Deferred federal income taxes reflect the future tax consequences of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end. We account for income taxes under the asset and liability method, which requires the recognition of deferred taxes for temporary differences between the financial statement and tax return basis of assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in future years for which we have already recorded the tax benefit in our income statement. Deferred tax liabilities generally represent tax expense recognized in our financial statements for which payment has been deferred or expenditures for which we have already taken a deduction in our tax return but have not yet been recognized in our financial statements. Under GAAP, we are required to evaluate the recoverability of our deferred tax assets and establish a valuation allowance if necessary to reduce our deferred tax assets to an amount that is more likely than not to be realized. Significant judgment is required in determining whether valuation allowances should be established, as well as the amount of such allowances. We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to realize the value of the deferred tax assets. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income and tax-planning strategies that would result in the realization of deferred tax assets. The underlying assumptions we use in forecasting future taxable income require significant judgment and take into account our recent performance. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible or creditable. If actual experience differs from these estimates and assumptions, the recognized deferred tax asset value may not be fully realized, resulting in an increase to income tax expense in our results of operations. As of September 30, 2022, the Company maintained a full valuation allowance of $30.4 million against its deferred tax assets because we determined that it is more likely than not that these assets will not be recoverable. If, in the future, we determine we can support the recoverability of all or a portion of the deferred tax assets under the guidance, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets will be accounted for as a reduction of income tax expense and result in an increase in equity. Changes in tax laws and rates may affect recorded deferred tax assets and liabilities and our effective tax rate in the future. ​ The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions at September 30, 2022. ​ Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ("ASU 2020-04"). ASU 2020-04 provides optional guidance for a limited period of time to ease potential accounting impact associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate ("LIBOR"). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in ASU 2020-04 could be adopted as of March 12, 2020 and are effective through December 31, 2024. We do not currently have any contracts that have been changed to a new reference rate and do not expect the adoption of this guidance to have a material effect on the Company’s results of operations, financial position or liquidity. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016-13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. As a smaller reporting company, ASU 2016-13 is effective for fiscal years of the Company beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016-13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures.

Discontinued Operations and Held for Sale Classification	3. Discontinued Operations and Held for Sale Classification On October 7, 2022 the Company consummated the sale of substantially all of its excess and surplus lines operations to Core Specialty Insurance Holdings, Inc. (“Core Specialty”), a specialty property and casualty insurer, for $40.0 million cash consideration, plus an estimated $19.2 million consideration for the acquisition costs associated with certain net unearned premium reserves. The Company retained the related loss and loss adjustment expenses (“LAE”) reserves of its excess and surplus lines businesses and will experience future cash outflows and change in estimates for these reserves until all claims have been settled. As of September 30, 2022 the expected net liability amount recorded related to these future outflows are $209.5 million, which are included in reserves for unpaid losses and LAE and reinsurance recoverable in our Consolidated Balance Sheets. At this time, a date in which all claims will be settled is not known. The transaction was comprised of substantially all of nine business units within the Company’s former Specialty Commercial Segment, certain related assets and liabilities, and the immediate transition to Core Specialty of approximately 200 employees who produce and support these lines of businesses.

Fair Value [Abstract]
Fair Value	4. Fair Value ASC 820 defines fair value, establishes a consistent framework for measuring fair value and requires disclosure about fair value measurements. ASC 820, among other things, requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In addition, ASC 820 precludes the use of block discounts when measuring the fair value of instruments traded in an active market, which were previously applied to large holdings of publicly traded equity securities. We determine the fair value of our financial instruments based on the fair value hierarchy established in ASC 820. In accordance with ASC 820, we utilize the following fair value hierarchy: ● Level 1: quoted prices in active markets for identical assets; ● Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, inputs of identical assets for less active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument; and ● Level 3: inputs to the valuation methodology that are unobservable for the asset or liability. This hierarchy requires the use of observable market data when available. Under ASC 820, we determine fair value based on the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy described above. Fair value measurements for assets and liabilities where there exists limited or no observable market data are calculated based upon our pricing policy, the economic and competitive environment, the characteristics of the asset or liability and other factors as appropriate. These estimated fair values may not be realized upon actual sale or immediate settlement of the asset or liability. Where quoted prices are available on active exchanges for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include equity securities. Level 2 investment securities include corporate bonds, collateralized corporate bank loans, municipal bonds, U.S. Treasury securities, other obligations of the U.S. Government and mortgage-backed securities for which quoted prices are not available on active exchanges for identical instruments. We use third-party pricing services to determine fair values for each Level 2 investment security in all asset classes. Since quoted prices in active markets for identical assets are not available, these prices are determined using observable market information such as quotes from less active markets and/or quoted prices of securities with similar characteristics, among other things. We have reviewed the processes used by the pricing services and have determined that they result in fair values consistent with the requirements of ASC 820 for Level 2 investment securities. We have not adjusted any prices received from third-party pricing sources. There were no transfers between Level 1 and Level 2 securities. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy. Level 3 investments are valued based on the best available data in order to approximate fair value. This data may be internally developed and consider risk premiums that a market participant would require. Investment securities classified within Level 3 include other less liquid investment securities. The following table presents, for each of the fair value hierarchy levels, assets that are measured at fair value on a recurring basis at September 30, 2022 and December 31, 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2022 ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ Active Markets for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Identical Assets ​ Other Observable ​ Unobservable ​ ​ ​ ​ (Level 1) Inputs (Level 2) Inputs (Level 3) Total U.S. Treasury securities and obligations of U.S. Government ​ $ — ​ $ 41,132 ​ $ — ​ $ 41,132 Corporate bonds ​ — ​ 257,409 ​ — ​ 257,409 Corporate bank loans ​ — ​ 75,011 ​ — ​ 75,011 Municipal bonds ​ — ​ 42,024 ​ — ​ 42,024 Mortgage-backed ​ — ​ 1,477 ​ — ​ 1,477 Total debt securities ​ — ​ 417,053 ​ — ​ 417,053 Total equity securities ​ 41,002 ​ — ​ — ​ 41,002 Total investments ​ $ 41,002 ​ $ 417,053 ​ $ — ​ $ 458,055 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2021 ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ Active Markets for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Identical Assets ​ Other Observable ​ Unobservable ​ ​ ​ ​ (Level 1) Inputs (Level 2) Inputs (Level 3) Total U.S. Treasury securities and obligations of U.S. Government ​ $ — ​ $ 62,984 ​ $ — ​ $ 62,984 Corporate bonds ​ — ​ 105,234 ​ 347 ​ 105,581 Corporate bank loans ​ — ​ 81,189 ​ — ​ 81,189 Municipal bonds ​ — ​ 38,464 ​ — ​ 38,464 Mortgage-backed ​ — ​ 1,855 ​ — ​ 1,855 Total debt securities ​ — ​ 289,726 ​ 347 ​ 290,073 Total equity securities ​ 48,695 ​ — ​ — ​ 48,695 Total investments ​ $ 48,695 ​ $ 289,726 ​ $ 347 ​ $ 338,768 ​ Due to significant unobservable inputs into the valuation model for one corporate bond as of December 31, 2021, we classified this investment as Level 3 in the fair value hierarchy. The corporate bond is a convertible senior note and its fair value was estimated by the sum of the bond value using an income approach discounting the scheduled interest and principal payments and the conversion feature utilizing a binomial lattice model. ​ The following table summarizes the changes in fair value for all financial assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the nine months ended September 30, 2022 and 2021 (in thousands): ​ ​ ​ ​ Beginning balance as of January 1, 2022 $ 347 Sales ​ — Settlements ​ (347) Purchases ​ — Issuances ​ — Total realized/unrealized losses included in net income ​ — Net gain included in other comprehensive income ​ — Transfers into Level 3 ​ — Transfers out of Level 3 ​ — Ending balance as of September 30, 2022 ​ $ — ​ ​ ​ ​ ​ Beginning balance as of January 1, 2021 $ 348 Sales ​ — Settlements ​ — Purchases ​ — Issuances ​ — Total realized/unrealized gains included in net loss ​ — Net gains included in other comprehensive loss ​ 8 Transfers into Level 3 ​ — Transfers out of Level 3 ​ — Ending balance as of September 30, 2021 ​ $ 356 ​

We held a total of 100 debt securities with an unrealized loss, of which 74 were in an unrealized loss position for less than one year and 26 were in an unrealized loss position for a period of one year or greater, as of December 31, 2021. We consider these losses as a temporary decline in value as they are on securities that we do not intend to sell and do not believe we will be required to sell prior to recovery of our amortized cost basis. The gross unrealized losses on the debt security positions at September 30, 2022 and December 31, 2021 were due predominately to market and interest rate fluctuations and we see no other indications that the decline in values of these securities is other-than-temporary. Based on evidence gathered through our normal credit evaluation process, we presently expect that all debt securities held in our investment portfolio will be paid in accordance with their contractual terms. Nonetheless, it is at least reasonably possible that the performance of certain issuers of these debt securities will be worse than currently expected resulting in future write-downs within our portfolio of debt securities. We complete a detailed analysis each quarter to assess whether any decline in the fair value of any debt security below cost is deemed other-than-temporary. All debt securities with an unrealized loss are reviewed. We recognize an impairment loss when a debt security’s value declines below cost, adjusted for accretion, amortization and previous other-than-temporary impairments and it is determined that the decline is other-than-temporary. We did not recognize any impairment loss on debt securities during the nine months ended September 30, 2022. During the nine months ended September 30, 2021, we disposed of $0.6 million of previously impaired securities. Debt Investments: We assess whether we intend to sell, or it is more likely than not that we will be required to sell, a fixed maturity investment before recovery of its amortized cost basis less any current period credit losses. For fixed maturity investments that are considered other-than-temporarily impaired and that we do not intend to sell and will not be required to sell, we separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the investment’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the investment’s fair value and the present value of future expected cash flows is recognized in other comprehensive income. Equity Investments: Equity investments that are not consolidated or accounted for under the equity method of accounting with readily determinable fair values are not required to be evaluated for other-than-temporary-impairment. ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized Cost Fair Value ​ ​ (in thousands) Due in one year or less ​ $ 114,153 ​ $ 112,798 Due after one year through five years ​ 249,384 ​ ​ 243,358 Due after five years through ten years ​ 55,046 ​ ​ 53,097 Due after ten years ​ 6,732 ​ ​ 6,323 Mortgage-backed ​ 1,555 ​ ​ 1,477 ​ ​ $ 426,870 ​ $ 417,053 ​

Share-Based Payment Arrangements [Abstract]
Share-Based Payment Arrangements	8. Share-Based Payment Arrangements Our 2015 Long Term Incentive Plan (“2015 LTIP”) was approved by shareholders on May 29, 2015. There are 2,000,000 shares authorized for issuance under the 2015 LTIP. As of September 30, 2022, restricted stock units representing the right to receive up to 1,071,060 shares of our common stock were outstanding under the 2015 LTIP. There were no stock options outstanding under the 2015 LTIP as of September 30, 2022. ​ Stock Options: There were no stock options outstanding at any point during the nine months ended September 30, 2022. There were no stock options granted, exercised or forfeited during the nine months ended September 30, 2022 or 2021, respectively. As of September 30, 2022, there was no unrecognized compensation cost related to non-vested stock options. Restricted Stock Units: Restricted stock units awarded under the 2015 LTIP represent the right to receive shares of common stock upon the satisfaction of vesting requirements, performance criteria and other terms and conditions. For grants issued prior to 2021, restricted stock units vest and shares of common stock become issuable on March 31 of the third calendar year following the year of grant if performance criteria have been satisfied. Restricted stock units awarded under the 2015 LTIP during 2021 and 2022 cumulatively vest up to 50%, 80% and 100%, and shares of common stock become issuable, on March 31 of the third, fourth and fifth calendar years, respectively, following the year of grant if performance criteria have been satisified. The performance criteria for restricted stock units vary based on grantee. The number of shares of common stock to be received ranges from 50% to 150% of the number of restricted stock units granted based on the level of achievement of the performance criteria. Grantees of restricted stock units do not have any rights of a stockholder, and do not participate in any distributions to our common stockholders, until the award fully vests upon satisfaction of the vesting schedule, performance criteria and other conditions set forth in their award agreement. Therefore, unvested restricted stock units are not considered participating securities under ASC 260, “Earnings Per Share” (Topic 260), and are not included in the calculation of basic or diluted earnings per share. Compensation cost is measured as an amount equal to the fair value of the restricted stock units on the date of grant and is expensed over the vesting period if achievement of the performance criteria is deemed probable, with the amount of the expense recognized based on our best estimate of the ultimate achievement level. The grant date fair value of restricted stock units granted in 2018, 2019, 2021and 2022 was $10.87, $18.10, $4.21 and $3.62 per unit, respectively. We incurred compensation expense (benefit) of ($203) thousand and $233 thousand related to restricted stock units during the three months and nine months ended September 30, 2022, respectively.

Reinsurance [Abstract]
Reinsurance	10. Reinsurance We reinsure a portion of the risk we underwrite in order to control the exposure to losses and to protect capital resources. We cede to reinsurers a portion of these risks and pay premiums based upon the risk and exposure of the policies subject to such reinsurance. Ceded reinsurance involves credit risk and is generally subject to aggregate loss limits. Although the reinsurer is liable to us to the extent of the reinsurance ceded, we are ultimately liable as the direct insurer on all risks reinsured. Reinsurance recoverables are reported after allowances for uncollectible amounts. We monitor the financial condition of reinsurers on an ongoing basis and review our reinsurance arrangements periodically. Reinsurers are selected based on their financial condition, business practices and the price of their product offerings. In order to mitigate credit risk to reinsurance companies, most of our reinsurance recoverable balance as of September 30, 2022 was with reinsurers that had an A.M. Best rating of “A-” or better. We also mitigate our credit risk for the remaining reinsurance recoverable by obtaining letters of credit. ​ The following table shows earned premiums ceded and reinsurance loss recoveries for continuing operations by period (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ September 30, September 30, ​ 2022 2021 2022 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Ceded earned premiums $ 16,866 $ 16,181 $ 51,265 $ 60,651 Reinsurance recoveries $ 21,092 $ 32,405 $ 75,395 $ 84,913 ​ Loss Portfolio Transfer ​ On July 16, 2020, AHIC, HIC, HSIC, HCM and HNIC (collectively, the “Hallmark Insurers”), entered into a Loss Portfolio Transfer Reinsurance Contract to be effective as of January 1, 2020 (the “LPT Contract”) with DARAG Bermuda Ltd. (“DARAG Bermuda”) and DARAG Insurance (Guernsey) Limited (“DARAG Guernsey” and, collectively, the “Reinsurers”). The LPT Contract was consummated on July 31, 2020. The Company recorded a $21.7 million pre-tax loss during the third quarter of 2020 attributable to the closing of the LPT Contract. ​ Pursuant to the LPT Contract, (a) the Hallmark Insurers ceded to the Reinsurers all existing and future claims for losses occurring on or prior to December 31, 2019 on the binding primary commercial automobile liability insurance policies and the brokerage primary commercial automobile liability insurance policies issued by the Hallmark Insurers (the “Subject Business”) up to an aggregate limit of $240.0 million, with (i) the first layer of $151.2 million in reinsurance provided by DARAG Bermuda, (ii) the Hallmark Insurers retaining a loss corridor of the next $24.9 million in losses on the Subject Business, (iii) DARAG Bermuda reinsuring a second layer of $27.8 million above the first layer and the Hallmark Insurers’ loss corridor, and (iv) DARAG Guernsey reinsuring the top layer of $36.1 million in losses on the Subject Business, in each case net of third-party reinsurance and other recoveries; (b) the Hallmark Insurers will continue to manage and retain the benefit of other third-party reinsurance on the Subject Business; and (c) the Hallmark Insurers paid the Reinsurers a net reinsurance premium of $92.6 million. In connection with the closing, the parties also entered into a Services Agreement and a Trust Agreement. Pursuant to the Services Agreement, DARAG Bermuda assumed responsibility for certain administrative services, including claims handling, for the Subject Business. Pursuant to the Trust Agreement, the Reinsurers made initial cash deposits in the aggregate amount of $96.7 million into collateral trust accounts with The Bank of New York Mellon, as trustee, to be held as security for the Reinsurers’ obligations to the Hallmark Insurers under the LPT Contract. ​ The Reinsurers and the Hallmark Insurers have submitted to binding arbitration a dispute that has arisen regarding the rights and obligations of the parties under the LPT Contract. Pending resolution of the dispute, the Hallmark Insurers have agreed to fund the payment of claims under the LPT contract without prejudice to their right to seek reimbursement and other relief in the arbitration proceedings. (See Note 18.) As of September 30, 2022, our consolidated balance sheet included a $62.0 million account receivable from DARAG related to the Hallmark Insurers funding claim payments under the LPT contract pending resolution of the dispute. ​ As of September 30, 2022, the ultimate incurred losses from the subject business were $282.8 million or $42.8 million in excess of the aggregate limit of $240.0 million. Our reinsurance recoverables of $542.8 million include a $12.5 million payable related to the LPT Contract as of September 30, 2022.

Subordinated Debt Securities	11. Subordinated Debt Securities We issued trust preferred securities through Trust I and Trust II. These Delaware statutory trusts are sponsored and wholly-owned by Hallmark and each was created solely for the purpose of issuing the trust preferred securities. Each trust pays dividends on its preferred securities at the same rate each quarter as interest is paid on the junior subordinated debt securities. Under the terms of the junior subordinated debt securities, we pay interest only each quarter and the principal of each note at maturity.

Senior Unsecured Notes [Abstract]
Senior Unsecured Notes	12. Senior Unsecured Notes On August 19, 2019, Hallmark issued $50.0 million of senior unsecured notes (“Notes”) due August 15, 2029. Interest on the Notes accrues at the rate of 6.25% per annum and is payable semi-annually in arrears commencing February 15, 2020. The Notes are not obligations of or guaranteed by any of Hallmark’s subsidiaries and are not subject to any sinking fund requirements. At Hallmark’s option, the Notes are redeemable, in whole or in part, prior to the stated maturity subject to certain provisions intended to make the holders of the Notes whole on scheduled interest and principal payments. The indenture governing the Notes contains covenants which, among other things, restrict Hallmark’s ability to incur additional indebtedness, make certain payments, create liens on the stock of certain subsidiaries, dispose of certain assets, or merge or consolidate with other entities. The terms of the indenture prohibit payments or other distributions on any security of the Company that ranks junior to the Notes when the Company’s debt to capital ratio (as defined in the indenture) is greater than 35%. The Company’s debt to capital ratio was 62.0% as of September 30, 2022. ​

Commitments and Contingencies [Abstract]
Commitments and Contingencies	18. Commitments and Contingencies ​ The Reinsurers and the Hallmark Insurers have submitted to binding arbitration a dispute that has arisen regarding the rights and obligations of the parties under the LPT Contract. (See Note 10.) Pending resolution of the dispute, the Hallmark Insurers have agreed to fund the payment of claims under the LPT Contract without prejudice to their right to seek reimbursement and other relief in the arbitration proceedings. The arbitration panel has been constituted and a final hearing on the merits is anticipated in the first quarter of 2023. In the arbitration, the Reinsurers seek rescission of the LPT Contract or, in the alternative, damages on the basis of alleged breach and fraudulent inducement by the Hallmark Insurers. The Company believes any such claims are without factual basis or legal merit and intends to vigorously contest the matter. The Company is seeking an arbitration award enforcing the terms of the LPT Contract and requiring the Reinsurers to reimburse the Hallmark Insurers for all claim amounts funded by them during the pendency of the arbitration, as well as all other damages sustained by the Hallmark Insurers. The arbitration panel has ordered that the Reinsurers post security for any final award in the amount of the Minimum Funding Requirement (as defined in the LPT Contract). Although an adverse arbitration outcome is at least reasonably possible, we are unable at this time to reasonably estimate the amount or range of possible loss in such event. ​ As of September 30, 2022 we were engaged in various other legal proceedings in the ordinary course of business, none of which, either individually or in the aggregate, are believed likely to have a material adverse effect on our consolidated financial position or results of operations, in the opinion of management. The various legal proceedings to which we were a party are routine in nature and incidental to our business. From time to time, assessments are levied on us by the guaranty association of the states where we offer our insurance products. Such assessments are made primarily to cover the losses of policyholders of insolvent or rehabilitated insurers. Since these assessments can generally be recovered through a reduction in future premium taxes paid, we capitalize the assessments that can be recovered as they are paid and amortize the capitalized balance against our premium tax expense. We did no t pay an assessment during the first nine months of 2022 or 2021. ​

Subsequent Event	Subsequent Event On October 7, 2022 the Company consummated the sale of substantially all of its excess and surplus lines operations to Core Specialty Insurance Holdings, Inc. (“Core Specialty”), a specialty property and casualty insurer, for $40.0 million cash consideration, plus an estimated $19.2 million consideration for the acquisition costs associated with certain net unearned premium reserves. The transaction was comprised of all or portions of nine business units within the Company’s former Specialty Commercial Segment, certain related assets and liabilities, and the immediate transition to Core Specialty of approximately 200 employees who produce and support these lines of businesses. Core Specialty’s acquisition and assumption of the Company’s excess and surplus lines of business and the related assets and liabilities was made effective as of September 30, 2022.
Use of Estimates in the Preparation of the Financial Statements	Use of Estimates in the Preparation of the Financial Statements Our preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect our reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting period. Refer to “Critical Accounting Estimates and Judgments” under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021 for information on accounting policies that we consider critical in preparing our consolidated financial statements. Actual results could differ materially from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value estimates are made at a point in time based on relevant market data as well as the best information available about the financial instruments. Fair value estimates for financial instruments for which no or limited observable market data is available are based on judgments regarding current economic conditions, credit and interest rate risk. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the instrument. In addition, changes in the underlying assumptions used in the fair value measurement technique, including discount rate and estimates of future cash flows, could significantly affect these fair value estimates. Cash and Cash Equivalents Restricted Cash Senior Unsecured Notes Due 2029 Subordinated Debt Securities For accounts receivable, reinsurance balances, premiums receivable, federal income tax recoverable and other assets, the carrying amounts are held at net realizable value which approximates fair value because of the short maturity of such financial instruments.
Variable Interest Entities	Variable Interest Entities On June 21, 2005, we formed Hallmark Statutory Trust I (“Trust I”), an unconsolidated trust subsidiary, for the sole purpose of issuing $30.0 million in trust preferred securities. Trust I used the proceeds from the sale of these securities and our initial capital contribution to purchase $30.9 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust I, and the payments under the debt securities are the sole revenues of Trust I. On August 23, 2007, we formed Hallmark Statutory Trust II (“Trust II”), an unconsolidated trust subsidiary, for the sole purpose of issuing $25.0 million in trust preferred securities. Trust II used the proceeds from the sale of these securities and our initial capital contribution to purchase $25.8 million of subordinated debt securities from Hallmark. The debt securities are the sole assets of Trust II, and the payments under the debt securities are the sole revenues of Trust II. We evaluate on an ongoing basis our investments in Trust I and Trust II (collectively the “Trusts”) and have determined that we do not have a variable interest in the Trusts. Therefore, the Trusts are not included in our consolidated financial statements.
Income Taxes	Income Taxes We file a consolidated federal income tax return. Deferred federal income taxes reflect the future tax consequences of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year end. We account for income taxes under the asset and liability method, which requires the recognition of deferred taxes for temporary differences between the financial statement and tax return basis of assets and liabilities. Deferred tax assets generally represent items that can be used as a tax deduction or credit in future years for which we have already recorded the tax benefit in our income statement. Deferred tax liabilities generally represent tax expense recognized in our financial statements for which payment has been deferred or expenditures for which we have already taken a deduction in our tax return but have not yet been recognized in our financial statements. Under GAAP, we are required to evaluate the recoverability of our deferred tax assets and establish a valuation allowance if necessary to reduce our deferred tax assets to an amount that is more likely than not to be realized. Significant judgment is required in determining whether valuation allowances should be established, as well as the amount of such allowances. We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to realize the value of the deferred tax assets. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income and tax-planning strategies that would result in the realization of deferred tax assets. The underlying assumptions we use in forecasting future taxable income require significant judgment and take into account our recent performance. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible or creditable. If actual experience differs from these estimates and assumptions, the recognized deferred tax asset value may not be fully realized, resulting in an increase to income tax expense in our results of operations. As of September 30, 2022, the Company maintained a full valuation allowance of $30.4 million against its deferred tax assets because we determined that it is more likely than not that these assets will not be recoverable. If, in the future, we determine we can support the recoverability of all or a portion of the deferred tax assets under the guidance, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets will be accounted for as a reduction of income tax expense and result in an increase in equity. Changes in tax laws and rates may affect recorded deferred tax assets and liabilities and our effective tax rate in the future. ​ The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions at September 30, 2022.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ("ASU 2020-04"). ASU 2020-04 provides optional guidance for a limited period of time to ease potential accounting impact associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate ("LIBOR"). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in ASU 2020-04 could be adopted as of March 12, 2020 and are effective through December 31, 2024. We do not currently have any contracts that have been changed to a new reference rate and do not expect the adoption of this guidance to have a material effect on the Company’s results of operations, financial position or liquidity. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016-13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. As a smaller reporting company, ASU 2016-13 is effective for fiscal years of the Company beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016-13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures.
