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, 2022 included in our Annual Report on Form 10-K filed with the SEC. The interim financial data as of March 31, 2023 and 2022 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 March 31, 2023 are not necessarily indicative of the operating results to be expected for the full year. Subsequent Event AHIC, HIC, HSIC, HCM and HNIC (collectively, the “Hallmark Insurers”) are parties to a Loss Portfolio Transfer Reinsurance Contract (the “LPT Contract”) and related agreements with DARAG Bermuda Ltd. (“DARAG Bermuda”) and DARAG Insurance (Guernsey) Limited (“DARAG Guernsey” and, collectively, the “Reinsurers”). The Reinsurers and the Hallmark Insurers agreed to submit to binding arbitration a dispute regarding the rights and obligations of the parties under the LPT Contract. The Company established a receivable of $58.9 million pending a resolution of the matter. An interim binding arbitration award was declared by the arbitration panel on May 4, 2023. In accordance with GAAP, the Company recognized in the current reporting period a write-off to bad debt expense of $32.9 million of the receivable established by the Company. As of March 31, 2023, our consolidated balance sheet included $4.0 million of account receivable from DARAG related to cost incurred in which we contend we have right of reimbursement. A definitive binding award is expected to be forthcoming in the near future which may increase or decrease our total write-off. On May 5, 2023 AM Best downgraded the Long-Term Issuer Credit Rating (Long-Term ICR) to “bb” (Fair) from “bbb-” (Good) and associated Long-Term Issue Ratings (Long-Term IRs) of the Hallmark insurance subsidiaries. Concurrently, AM Best downgraded the Financial Strength Rating (FSR) to B++ (Good) from A- (Excellent) and the Long-Term ICRs to “bbb” (Good) from “a-” (Excellent). The B++ rating applied to AHIC, HIC, HSIC, HNIC and HCM. In addition, AM Best maintained the under review with negative implications status of all Credit Ratings (ratings). On May 9, 2023 AM Best further downgraded, due to the outcome of the DARAG arbitration, the Long-Term ICR to “ccc-” (Weak) from “bb” (Fair) and associated Long-Term IRs of the Hallmark insurance subisidiares. Concurrently, AM Best further downgraded the FSR to C++ (Marginal) from B++ (Good) and the Long-Term ICRs to “b+” (Marginal) from “bbb” (Good). The C++ rating applies to AHIC, HIC, HSIC, HNIC and HCM. A.M. Best has indicated a negative outlook for each of the ratings assigned to these insurance company subsidiaries. On May 14, 2023 the Company submitted notice to AM Best to withdraw from AM Best’s interactive rating process. We will be assigned a Non-Rating Designation of NR by AM Best, which are assigned to insurance companies that are not rated. On May 5, 2023, the Company entered into an agreement with an A.M. Best rated “A” insurance company to continue to write new business in circumstances that require an A.M. Best financial strength rating higher than our own. The cost structure of the remaining business is negatively impacted by the additional expense associated with the aforementioned agreement Further, certain terms of the agreement are variable based on the amount of Company surplus. Such adjustments may cause the rated “A” insurance company to terminate the agreement or Hallmark to determine it is not in its best interest to continue to write new business pursuant to the agreement. The Company could be obligated to incur minimum costs of $250,000 plus assessments and state premium taxes in the event it were to elect to discontinue writing new business pursuant to the agreement . 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, 2022 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 March 31, 2023, the Company maintained a full valuation allowance of $39.0 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 March 31, 2023. ​ Reverse Stock Split On November 29, 2022, we filed a Certificate of Change to our Articles of Incorporation to affect a reverse split of our issued and outstanding common stock on a one-for-ten one-for-ten ​ 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 replaces the existing incurred loss impairment model with an expected credit loss impairment model. The expected credit loss impairment model requires the entity to recognize its estimate of expected credit losses for affected financial assets using an allowance for credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected. The income statement includes the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have occurred during the period. Credit losses on available-for-sale debt securities are measured in a manner similar to current GAAP, although ASU 2016-13 requires that they be presented as an allowance rather than as a write-down of the amortized cost. In situations where the estimate of credit loss on an available-for-sale debt security declines, entities will be able to record a reversal of the allowance to income in the current period, which was prohibited prior to the adoption of ASU 2016-13. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. The standard also requires expanded disclosures related to credit losses and credit quality indicators. 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. Application of the standard to our applicable assets, including debt securities, cash, premium receivable, accounts receivable, reinsurance recoverables and prepaid expenses, did not have a material impact on our financial results. After consideration of risk and qualitative factors for each asset type in scope, an allowance for expected credit losses of $200 thousand was established in regards to reinsurance recoverables. See ‘Note 5. Investments” for a discussion regarding expected credit loss on our debt security assets. For determination of the reinsurance recoverables expected credit loss allowance, our Company relies on external ratings of credit worthiness from A.M. Best and collectability of recorded amounts considering letters of credit pledged by reinsurance partners. The ratings at March 31, 2023 of our reinsurance recoverables not offset by our liabilities for amounts owed to reinsurers and pledged letters of credit are 96% rated A- or better, 1% rated B++ or B+ and 3% all other lower ratings.

Discontinued Operations Classification [Abstract]
Discontinued Operations Classification	3. Discontinued Operations 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”) for $40.0 million cash consideration, plus an estimated $19.9 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. 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 March 31, 2023 and December 31, 2022 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of March 31, 2023 ​ 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 ​ $ — ​ $ 54,627 ​ $ — ​ $ 54,627 Corporate bonds ​ — ​ 197,231 ​ — ​ 197,231 Corporate bank loans ​ — ​ 54,015 ​ — ​ 54,015 Municipal bonds ​ — ​ 32,844 ​ — ​ 32,844 Mortgage-backed ​ — ​ 1,337 ​ — ​ 1,337 Total debt securities ​ — ​ 340,054 ​ — ​ 340,054 Total equity securities ​ 22,392 ​ — ​ — ​ 22,392 Total investments ​ $ 22,392 ​ $ 340,054 ​ $ — ​ $ 362,446 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 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 ​ $ — ​ $ 79,978 ​ $ — ​ $ 79,978 Corporate bonds ​ — ​ 235,044 ​ — ​ 235,044 Corporate bank loans ​ — ​ 75,183 ​ — ​ 75,183 Municipal bonds ​ — ​ 35,018 ​ — ​ 35,018 Mortgage-backed ​ — ​ 1,374 ​ — ​ 1,374 Total debt securities ​ — ​ 426,597 ​ — ​ 426,597 Total equity securities ​ 28,199 ​ — ​ — ​ 28,199 Total investments ​ $ 28,199 ​ $ 426,597 ​ $ — ​ $ 454,796 ​ There were no investments classified as Level 3 as of March 31, 2023 and 2022.

We held a total of 228 debt securities with an unrealized loss, of which 181 were in an unrealized loss position for less than one year and 47 were in an unrealized loss position for a period of one year or greater, as of December 31, 2022. 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 March 31, 2023 and December 31, 2022 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. Additionally, in accordance with ASU 2016-13, the Company estimates what is expected to not be collectable over the remaining life of its debt securities by employing qualitative analysis, considering among other factors positions in unrealized losses without consideration of time spent in such position. The Company concluded that there is currently no expected credit loss allowance necessary. 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 no t recognize any impairment loss on debt securities during the three months ended March 31, 2023. During the three months ended March 31, 2023 and 2022, we did no t dispose of any 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 through a credit loss allowance 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. The amortized cost and estimated fair value of debt securities at March 31, 2023 by contractual maturity are as follows. Expected maturities may differ from contractual maturities because certain borrowers may have the right to call or prepay obligations with or without penalties. ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized Cost Fair Value ​ ​ (in thousands) Due in one year or less ​ $ 174,859 ​ $ 172,720 Due after one year through five years ​ 139,088 ​ ​ 137,135 Due after five years through ten years ​ 23,022 ​ ​ 22,807 Due after ten years ​ 6,261 ​ ​ 6,055 Mortgage-backed ​ 1,484 ​ ​ 1,337 ​ ​ $ 344,714 ​ $ 340,054 ​

Our Commercial Accounts business unit overall experienced net unfavorable development primarily in accident years 2021 and 2022 from CAT related events offset, in part, by our Aviation business unit’s net favorable development of $0.3 million stemming from a 2019 accident year CAT related event. The run-off from our former Workers Compensation operating unit was relatively flat for the first quarter experiencing $0.1 million of net unfavorable development. ● Personal Segment. Net unfavorable development in our Specialty Personal Lines business unit was driven predominately by unfavorable development attributable to the 2021 and 2022 accident years due in part to rising inflationary trends, specifically loss costs, that the industry began experiencing in 2021. ● Runoff Segment. Net unfavorable development in our Runoff lines of business is solely attributable to the binding commercial automobile liability line of business in the 2020 and prior accident years due in part to exceeding the aggregate limit of the loss portfolio transfer agreement covering accident years 2019 and prior entered into during 2020 .

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 200,000 shares authorized for issuance under the 2015 LTIP. As of March 31, 2023, restricted stock units representing the right to receive up to 94,547 shares of our common stock were outstanding under the 2015 LTIP. There were no stock options outstanding under the 2015 LTIP as of March 31, 2023. ​ Stock Options: There were no stock options outstanding at any point during the three months ended March 31, 2023 or 2022. There were no stock options granted, exercised or forfeited during the three months ended March 31, 2023 or 2022, respectively. As of March 31, 2023, 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 2019, 2021 and 2022 was $181.00, $42.10 and $36.20 per unit, respectively. We incurred compensation expense of $97 thousand and $62 thousand related to restricted stock units during the three months ended March 31, 2023 and 2022, respectively. We recorded income tax benefit of $20 thousand and $13 thousand related to restricted stock units during the three months ended March 31, 2023 and 2022, respectively. ​ The following table details the status of our restricted stock units as of and for the three months ended March 31, 2023 and 2022. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of Restricted Stock Units ​ ​ 2023 2022 ​ Nonvested at January 1 69,316 58,169 ​ Granted — 831 ​ Vested — (1,795) ​ Forfeited (6,285) (5,993) ​ Nonvested at March 31 63,031 51,212 ​ ​ As of March 31, 2023, there was $1.6 million of unrecognized grant date compensation cost related to unvested restricted stock units assuming compensation cost accrual at target achievement level. Based on the current performance estimate, we expect to recognize $0.8 million of compensation cost related to unvested restricted stock units, of which $0.3 million is expected to be recognized during the remainder of 2023, $0.3 million in 2024, $0.4 million in 2024, $0.1 million in 2026 and $0.1 million in 2027.

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 March 31, 2023 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.

(“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 submitted to binding arbitration a dispute that arose regarding the rights and obligations of the parties under the LPT Contract. An interim binding arbitration award was declared by the arbitration panel on May 4, 2023 (See Note 2, “Basis of Presentation – Subsequent Events”). A definitive binding award is expected to be forthcoming in the near future. In accordance with GAAP, the Company recognized in the current reporting period a write-off to bad debt expense of $32.9 million of the receivable established by the Company. As of March 31, 2023, our consolidated balance sheet included $4.0 million of account receivable from DARAG related to cost incurred in which we contend we have right of reimbursement.

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 81.7% as of March 31, 2023.

As of March 31, 2023, our consolidated balance sheet included $4.0 million of account receivable from DARAG related to cost incurred in which we contend we have right of reimbursement. ​ As of March 31, 2023 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 three months of 2023 or 2022.

Subsequent Event	Subsequent Event AHIC, HIC, HSIC, HCM and HNIC (collectively, the “Hallmark Insurers”) are parties to a Loss Portfolio Transfer Reinsurance Contract (the “LPT Contract”) and related agreements with DARAG Bermuda Ltd. (“DARAG Bermuda”) and DARAG Insurance (Guernsey) Limited (“DARAG Guernsey” and, collectively, the “Reinsurers”). The Reinsurers and the Hallmark Insurers agreed to submit to binding arbitration a dispute regarding the rights and obligations of the parties under the LPT Contract. The Company established a receivable of $58.9 million pending a resolution of the matter. An interim binding arbitration award was declared by the arbitration panel on May 4, 2023. In accordance with GAAP, the Company recognized in the current reporting period a write-off to bad debt expense of $32.9 million of the receivable established by the Company. As of March 31, 2023, our consolidated balance sheet included $4.0 million of account receivable from DARAG related to cost incurred in which we contend we have right of reimbursement. A definitive binding award is expected to be forthcoming in the near future which may increase or decrease our total write-off. On May 5, 2023 AM Best downgraded the Long-Term Issuer Credit Rating (Long-Term ICR) to “bb” (Fair) from “bbb-” (Good) and associated Long-Term Issue Ratings (Long-Term IRs) of the Hallmark insurance subsidiaries. Concurrently, AM Best downgraded the Financial Strength Rating (FSR) to B++ (Good) from A- (Excellent) and the Long-Term ICRs to “bbb” (Good) from “a-” (Excellent). The B++ rating applied to AHIC, HIC, HSIC, HNIC and HCM. In addition, AM Best maintained the under review with negative implications status of all Credit Ratings (ratings). On May 9, 2023 AM Best further downgraded, due to the outcome of the DARAG arbitration, the Long-Term ICR to “ccc-” (Weak) from “bb” (Fair) and associated Long-Term IRs of the Hallmark insurance subisidiares. Concurrently, AM Best further downgraded the FSR to C++ (Marginal) from B++ (Good) and the Long-Term ICRs to “b+” (Marginal) from “bbb” (Good). The C++ rating applies to AHIC, HIC, HSIC, HNIC and HCM. A.M. Best has indicated a negative outlook for each of the ratings assigned to these insurance company subsidiaries. On May 14, 2023 the Company submitted notice to AM Best to withdraw from AM Best’s interactive rating process. We will be assigned a Non-Rating Designation of NR by AM Best, which are assigned to insurance companies that are not rated. On May 5, 2023, the Company entered into an agreement with an A.M. Best rated “A” insurance company to continue to write new business in circumstances that require an A.M. Best financial strength rating higher than our own. The cost structure of the remaining business is negatively impacted by the additional expense associated with the aforementioned agreement Further, certain terms of the agreement are variable based on the amount of Company surplus. Such adjustments may cause the rated “A” insurance company to terminate the agreement or Hallmark to determine it is not in its best interest to continue to write new business pursuant to the agreement. The Company could be obligated to incur minimum costs of $250,000 plus assessments and state premium taxes in the event it were to elect to discontinue writing new business pursuant to the agreement .
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, 2022 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 March 31, 2023, the Company maintained a full valuation allowance of $39.0 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 March 31, 2023. ​
Reverse Stock Split	Reverse Stock Split On November 29, 2022, we filed a Certificate of Change to our Articles of Incorporation to affect a reverse split of our issued and outstanding common stock on a one-for-ten one-for-ten
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 replaces the existing incurred loss impairment model with an expected credit loss impairment model. The expected credit loss impairment model requires the entity to recognize its estimate of expected credit losses for affected financial assets using an allowance for credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected. The income statement includes the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have occurred during the period. Credit losses on available-for-sale debt securities are measured in a manner similar to current GAAP, although ASU 2016-13 requires that they be presented as an allowance rather than as a write-down of the amortized cost. In situations where the estimate of credit loss on an available-for-sale debt security declines, entities will be able to record a reversal of the allowance to income in the current period, which was prohibited prior to the adoption of ASU 2016-13. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. The standard also requires expanded disclosures related to credit losses and credit quality indicators. 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. Application of the standard to our applicable assets, including debt securities, cash, premium receivable, accounts receivable, reinsurance recoverables and prepaid expenses, did not have a material impact on our financial results. After consideration of risk and qualitative factors for each asset type in scope, an allowance for expected credit losses of $200 thousand was established in regards to reinsurance recoverables. See ‘Note 5. Investments” for a discussion regarding expected credit loss on our debt security assets. For determination of the reinsurance recoverables expected credit loss allowance, our Company relies on external ratings of credit worthiness from A.M. Best and collectability of recorded amounts considering letters of credit pledged by reinsurance partners. The ratings at March 31, 2023 of our reinsurance recoverables not offset by our liabilities for amounts owed to reinsurers and pledged letters of credit are 96% rated A- or better, 1% rated B++ or B+ and 3% all other lower ratings.
