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 June 30, 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 June 30, 2023 are not necessarily indicative of the operating results to be expected for the full year. Subsequent Event Due to the Maui, Hawaii wildfires on August 9, 2023, we preliminarily estimate our net loss exposure to be $7.5 million plus additional cost in the form of reinstatement premiums to restore any necessary reinsurance layers. The net loss and any additional cost incurred will be recognized in our third quarter 2023 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 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 June 30, 2023, the Company maintained a full valuation allowance of $41.4 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 June 30, 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 required in accordance with U.S. GAAP, all common share and per share data are retrospectively restated to give effect of the Reverse Stock Split for all periods presented herein. ​ 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 increases or decreases of expected credit losses that occur 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, we are 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 requires us 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 and accordingly we adopted ASU 2016-13 effective with our March 31, 2023 interim reporting. 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.

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. This transaction met the criteria for discontinued operations accounting. As a result, the results of operations for the affected excess and surplus lines are included in discontinued operations in our Consolidated Statement of Operations for all periods shown. The following table summarizes income (loss) from discontinued operations (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ ​ 2023 ​ 2022 ​ 2023 ​ 2022 Gross premiums written ​ $ (75,225) ​ $ 126,062 ​ $ 29,229 ​ $ 217,688 Ceded premiums written ​ ​ 75,139 ​ ​ (79,199) ​ ​ (29,546) ​ ​ (133,773) Net premiums written ​ ​ (86) ​ ​ 46,863 ​ ​ (317) ​ ​ 83,915 Change in unearned premiums ​ ​ - ​ ​ (3,788) ​ ​ - ​ ​ 2,322 Net premiums earned ​ ​ (86) ​ ​ 43,075 ​ ​ (317) ​ ​ 86,237 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commissions and fees ​ ​ - ​ ​ 282 ​ ​ - ​ ​ 569 Other income ​ ​ 2,199 ​ ​ - ​ ​ 4,808 ​ ​ - ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenues ​ ​ 2,113 ​ ​ 43,357 ​ ​ 4,491 ​ ​ 86,806 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Losses and loss adjustment expenses ​ ​ (4,641) ​ ​ 39,287 ​ ​ (4,987) ​ ​ 63,929 Operating expenses ​ ​ 878 ​ ​ 6,916 ​ ​ 3,498 ​ ​ 14,866 Amortization of intangible assets ​ ​ - ​ ​ 119 ​ ​ - ​ ​ 238 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total expenses ​ ​ (3,763) ​ ​ 46,322 ​ ​ (1,489) ​ ​ 79,033 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income (loss) from discontinued operations before tax ​ $ 5,876 ​ $ (2,965) ​ $ 5,980 ​ $ 7,773 Income tax expense from discontinued operations ​ ​ - ​ ​ (583) ​ ​ - ​ ​ 1,697 Net income (loss) from discontinued operations ​ $ 5,876 ​ $ (2,382) ​ $ 5,980 ​ $ 6,076 ​

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 June 30, 2023 and December 31, 2022 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 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 ​ $ — ​ $ 22,435 ​ $ — ​ $ 22,435 Corporate bonds ​ — ​ 191,345 ​ — ​ 191,345 Corporate bank loans ​ — ​ 49,503 ​ — ​ 49,503 Municipal bonds ​ — ​ 31,240 ​ — ​ 31,240 Mortgage-backed ​ — ​ 1,238 ​ — ​ 1,238 Total debt securities ​ — ​ 295,761 ​ — ​ 295,761 Total equity securities ​ 22,763 ​ — ​ — ​ 22,763 Total investments ​ $ 22,763 ​ $ 295,761 ​ $ — ​ $ 318,524 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 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 June 30, 2023 and December 31, 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 unrealized 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 June 30, 2023 and December 31, 2022 were due predominately to market and interest rate fluctuations occurring in the ordinary course of business. Should we determine that a debt security in an unrealized loss position is likely to be sold before recovery of our amortized cost basis, we would recognize the unrealized loss. 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 that are in an unrealized loss position by employing qualitative analysis without regard for time spent in an unrealized loss position. The significant inputs used to determine the amount of expected credit loss in our debt security portfolio begins with an analysis of held securities experiencing credit rating downgrades in the current reporting period. Further inputs, such as performance indicators of the issuer’s business model, underlying assets, credit support and debt leverage are gathered as necessary based on our initial analysis step. If warranted, updated cash flow expectations are developed based on the aforementioned inputs. The Company concluded that based on current evidence there is no expected credit loss allowance necessary as of June 30, 2023. We presently expect that all debt securities held in our investment portfolio will be paid in accordance with their contractual terms. 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 June 30, 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 ​ $ 178,363 ​ $ 176,716 Due after one year through five years ​ 97,494 ​ ​ 95,891 Due after five years through ten years ​ 16,008 ​ ​ 15,958 Due after ten years ​ 6,226 ​ ​ 5,958 Mortgage-backed ​ 1,453 ​ ​ 1,238 ​ ​ $ 299,544 ​ $ 295,761 ​

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 June 30, 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 June 30, 2023. ​ Stock Options: There were no stock options outstanding at any point during the three or six months ended June 30, 2023 or 2022. There were no stock options granted, exercised or forfeited during the three or six months ended June 30, 2023 or 2022, respectively. As of June 30, 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 satisfied. 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 $42 thousand and $139 thousand related to restricted stock units during the three months and six months ended June 30, 2023, respectively. We incurred compensation expense of $374 thousand and $436 thousand related to restricted stock units during the three months and six months ended June 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 June 30, 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. The following table shows earned premiums ceded and reinsurance loss recoveries for continuing operations by period (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ June 30, June 30, ​ 2023 2022 2023 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Ceded earned premiums $ 14,106 $ 17,616 $ 29,451 $ 34,399 Reinsurance recoveries $ 15,226 $ 20,573 $ 24,243 $ 54,303 ​ 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. ​ 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 and consequently the Company recognized in the year-to-date reporting period ended March 31, 2023 a write-off to bad debt expense of $32.9 million of the receivable established by the Company. The final definitive binding award was declared June 2, 2023 and consequently an additional write-off to bad debt expense was recognized bringing the total write-off to $36.8 million for the year-to-date reporting period ended June 30, 2023. As of June 30, 2023, our consolidated balance sheet does not include any amount related to receivables from DARAG.

Subordinated Debt Securities [Abstract]
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. The subordinated debt securities of each trust are uncollateralized and do not require maintenance of minimum financial covenants. 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 trust subordinated debt securities, we pay interest only each quarter and the principal of each note at maturity. We may elect to defer payments of interest on the trust subordinated debt securities by extending the interest payment period for up to 20 consecutive quarterly periods. As of June 30, 2023, we have deferred interest for 11 consecutive quarters. During any such extension period, interest continues to accrue on the trust subordinated debt securities, as well as interest on such accrued interest. As of June 30, 2023, we have deferred $7.3 million of interest on the trust subordinated securities. The following table summarizes the nature and terms of the junior subordinated debt and trust preferred securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Hallmark ​ ​ Hallmark ​ ​ Statutory ​ ​ Statutory ​ ​ ​ Trust I ​ Trust II ​ ​ ​ ​ ​ ​ ​ Issue date ​ ​ June 21, 2005 ​ ​ August 23, 2007 Principal amount of trust preferred securities ​ $ 30,000 ​ $ 25,000 Principal amount of junior subordinated debt securities ​ $ 30,928 ​ $ 25,774 Maturity date of junior subordinated debt securities ​ ​ June 15, 2035 ​ ​ September 15, 2037 Trust common stock ​ $ 928 ​ $ 774 Interest rate, per annum ​ ​ Three Month LIBOR + 3.25% ​ ​ Three Month LIBOR + 2.90% Current interest rate at June 30, 2023 ​ ​ 8.80% ​ ​ 8.45% ​

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 89.5% as of June 30, 2023.

Commitments and Contingencies	18. Commitments and Contingencies ​ As of June 30, 2023 we were engaged in various 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 six months of 2023 or 2022.

We determine if a contract contains a lease at inception and recognize operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments at the commencement date. Since our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Lease agreements have lease and non-lease components, which are accounted for as a single lease component.

Basis of Presentation [Abstract]
Subsequent Event	Subsequent Event Due to the Maui, Hawaii wildfires on August 9, 2023, we preliminarily estimate our net loss exposure to be $7.5 million plus additional cost in the form of reinstatement premiums to restore any necessary reinsurance layers. The net loss and any additional cost incurred will be recognized in our third quarter 2023 financial statements.
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 June 30, 2023, the Company maintained a full valuation allowance of $41.4 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 June 30, 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 required in accordance with U.S. GAAP, all common share and per share data are retrospectively restated to give effect of the Reverse Stock Split for all periods presented herein.
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 increases or decreases of expected credit losses that occur 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, we are 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 requires us 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 and accordingly we adopted ASU 2016-13 effective with our March 31, 2023 interim reporting. 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 external rating is utilized to place our reinsurance recoverables into appropriate risk layers of expected loss considering duration and historical loss patterns. The ratings at June 30, 2023 of our reinsurance recoverables, not offset by our liabilities for amounts owed to reinsurers and pledged letters of credit, are 95% rated A- or better .
