Accounting Policies [Abstract]
Accounting Policies	1. General Hallmark Financial Services, Inc. (“Hallmark” and, together with subsidiaries, the “Company”, “we,” “us” or “our”) is an insurance holding company engaged in the sale of property/casualty insurance products to businesses and individuals. Our business involves marketing, distributing, underwriting and servicing our insurance products, as well as providing other insurance related services. We market, distribute, underwrite and service our property/casualty insurance products primarily through business units organized by products and distribution channel. Our business units are supported by our insurance company subsidiaries. Our Commercial Auto business unit offers primary and excess commercial vehicle insurance products and services; our E&S Casualty business unit offers primary and excess liability, excess public entity liability, E&S package and garage liability insurance products and services; our E&S Property business unit offers primary and excess commercial property insurance for both catastrophe and non-catastrophe exposures; our Professional Liability business unit offers healthcare and financial lines professional liability insurance products and services primarily for businesses, medical professionals, medical facilities and senior care facilities; and our Aerospace & Programs business unit offers general aviation and satellite launch property/casualty insurance products and services, as well as certain specialty programs. These products and services were previously reported as the Contract Binding and Specialty Commercial business units. Our Commercial Accounts business unit (f/k/a Standard Commercial P&C business unit) offers package and monoline property/casualty and occupational accident insurance products. Effective June 1, 2016 we ceased marketing new or renewal occupational accident policies. Our former Workers Compensation operating unit specialized in small and middle market workers compensation business. Effective July 1, 2015, we no longer market or retain any risk on new or renewal workers compensation policies. Our Specialty Personal Lines business unit offers non-standard personal automobile and renters insurance products and services. Our insurance company subsidiaries supporting these business units are American Hallmark Insurance Company of Texas (“AHIC”), Hallmark Insurance Company (“HIC”), Hallmark Specialty Insurance Company (“HSIC”), Hallmark County Mutual Insurance Company (“HCM”), Hallmark National Insurance Company (“HNIC”) and Texas Builders Insurance Company (“TBIC”). These business units are segregated into three reportable industry segments for financial accounting purposes. The Specialty Commercial Segment includes our Commercial Auto business unit, E&S Casualty business unit, E&S Property business unit, Professional Liability business unit and Aerospace & Programs business unit. The Standard Commercial Segment consists of the Commercial Accounts business unit and the runoff from our former Workers Compensation operating unit. The Personal Segment consists solely of our Specialty Personal Lines business unit. Basis of Presentation The accompanying consolidated financial statements include the accounts and operations of Hallmark and its subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) which, as to our insurance company subsidiaries, differ from statutory accounting practices prescribed or permitted for insurance companies by insurance regulatory authorities. Use of Estimates in the Preparation of Financial Statements Our preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities at the dates of the financial statements and our reported amounts of revenues and expenses during the reporting periods. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Since future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment may be reflected in the financial statements in future periods. The liability for unpaid claims and claims adjustment expenses and related amounts recoverable from reinsurers represents the most significant estimate in the accompanying financial statements, and any difference between such estimate and actual results could be material. Significant estimates in the accompanying financial statements also include the fair values of investments, deferred policy acquisition cost recoverability, deferred tax asset valuation, and fair value of goodwill and intangible assets. 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: The carrying amounts reported in the balance sheet for these instruments approximate their fair values. Restricted Cash: The carrying amount for restricted cash reported in the balance sheet approximates the fair value. Subordinated debt securities: Our trust preferred securities are reported at carry value of $55.9 million and $55.8 million, and had a fair value of $41.7 million and $45.6 million, as of December 31, 2019 and 2018, respectively, and would be included in Level 3 of the fair value hierarchy if they were reported at fair value. Senior unsecured notes due 2029: Our senior unsecured notes payable due in 2029 had a carry value of $49.1 million and a fair value of $49.8 million as of December 31, 2019. Our senior unsecured notes payable would be included in Level 3 of the fair value hierarchy if they were reported at fair value. For reinsurance balances, premiums receivable, federal income tax recoverable/payable, other assets and other liabilities, the carrying amounts approximate fair value because of the short maturity of such financial instruments. Investments Debt securities available for sale are reported at fair value. Unrealized gains and losses are recorded as a component of accumulated other comprehensive income (“AOCI”), net of related tax effects. Debt securities that are determined to have other-than-temporary impairment are recognized as a loss on investments in the consolidated statements of operations for the portion that is related to credit deterioration with the remaining portion recognized in other comprehensive income. Debt security premiums and discounts are amortized into earnings using the effective interest method. Maturities of debt securities and sales of equity securities are recorded in receivable for securities until the cash is settled. Purchases of debt and equity securities are recorded in payable for securities until the cash is settled. Equity securities are reported at fair value. On January 1, 2018, we adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 requires equity securities to be measured at fair value with changes in fair value recognized in net income. As a result of the new standard, equity securities with readily determinable fair values are no longer required to be evaluated for other-than-temporary impairment. Prior to the adoption of ASU 2016-01, unrealized gains and losses on equity securities were recorded as a component of AOCI, net of related tax effects. Other investments consist of an equity warrant which is reported at fair value. Unrealized gains and losses are reported in the statement of operations as a component of net realized gains (losses). Realized investment gains and losses are recognized in operations on the first in-first out method. Cash and Cash Equivalents Cash and cash equivalents include cash and highly liquid investments with an original maturity of three months or less. Restricted Cash Restricted cash represents amounts required to be set aside by a contractual agreement with a third-party insurer and amounts pledged for the benefit of various state insurance departments. Premiums Receivable Premiums receivable represent amounts due from policyholders or independent agents for premiums written and uncollected. These balances are carried at net realizable value. Reinsurance We are routinely involved in reinsurance transactions with other companies. Reinsurance premiums, losses and loss adjustment expenses (“LAE”) are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. (See Note 7.) Deferred Policy Acquisition Costs Policy acquisition costs (mainly direct commission, premium taxes, underwriting, marketing expenses and ceding commission) that are directly related to the successful acquisition of new and renewal insurance contracts are deferred and recognized to operations over periods in which the related premiums are earned. The method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. In determining estimated realizable value, the computation gives effect to the premium to be earned, expected investment income, losses and LAE and certain other costs expected to be incurred as the premiums are earned. If the computation results in an estimated net realizable value less than zero, a liability will be accrued for the premium deficiency. During 2019 and 2018, we deferred ($156.8) million and ($124.5) million of direct policy acquisition costs and amortized $141.0 million and $120.3 million of deferred direct policy acquisition costs, respectively. During 2019 and 2018, we deferred $160.8 million and $88.8 million of ceding commission acquisition costs and amortized ($153.7) million and ($82.9) million of deferred ceding commission acquisition costs, respectively. Therefore, the net amortization (deferrals) of policy acquisition costs were ($8.7) million and $1.7 million for 2019 and 2018, respectively. Business Combinations We account for business combinations using the acquisition method of accounting pursuant to Accounting Standards Codification (“ASC”) 805, “Business Combinations.” The base cash purchase price plus the estimated fair value of any non-cash or contingent consideration given for an acquired business is allocated to the assets acquired (including identified intangible assets) and liabilities assumed based on the estimated fair values of such assets and liabilities. The excess of the fair value of the total consideration given for an acquired business over the aggregate net fair values assigned to the assets acquired and liabilities assumed is recorded as goodwill. Contingent consideration is recognized as a liability at fair value as of the acquisition date with subsequent fair value adjustments recorded in the consolidated statements of operations. The valuation of contingent consideration requires assumptions regarding anticipated cash flows, probabilities of cash flows, discount rates and other factors. Significant judgment is employed in determining the propriety of these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions, can materially impact the amount of contingent consideration expense we record in any given period. Indirect and general expenses related to business combinations are expensed as incurred. Goodwill and Intangible Assets, net We account for our goodwill and intangible assets according to ASC 350, “Intangibles – Goodwill and Other.” Under ASC 350, intangible assets with a finite life are amortized over the estimated useful life of the asset. Goodwill and intangible assets with an indefinite useful life are not amortized. Goodwill and intangible assets are tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. For goodwill, we may perform a qualitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. The first step of the quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill (“Step 1”). If the fair value of a reporting unit exceeds its carrying value amount, goodwill of the reporting unit is not considered to have a potential impairment and the second step is not necessary. However, if the carrying amount of the reporting unit exceeds its fair value, the second step (“Step 2”) is performed to determine if goodwill is impaired and to measure the amount of impairment loss to recognize, if any. Step 2 compares the implied fair value of goodwill with the carrying amount of goodwill. If the implied value of goodwill is less than the carrying amount of goodwill, it is written down to its fair value with a corresponding expense reflected in the Consolidated Statements of Income. The implied goodwill is calculated based on a hypothetical purchase price allocation, similar to the requirements in the accounting guidance for business combinations, whereby the implied fair value of the reporting unit is allocated to the fair value of the assets and liabilities of the reporting unit. We have elected to perform our goodwill impairment test on the first day of the fourth quarter, October 1, of each year. Leases We have several leases, primarily for office facilities and computer equipment, which expire in various years through 2032. Some of these leases include rent escalation provisions throughout the term of the lease. We expense the average annual cost of the lease with the difference to the actual rent invoices recorded as a right of use asset and a lease obligation. Right of use assets and lease obligations are classified in other assets and in accounts payable and other accrued expenses, respectively, on our consolidated balance sheets. Property and Equipment Property and equipment (including leasehold improvements), aggregating $34.6 million and $27.0 million, at December 31, 2019 and 2018, respectively, which is included in other assets, is recorded at cost and is depreciated using the straight-line method over the estimated useful lives of the assets (three to ten years) or the life of the lease, whichever is shorter. Property and equipment includes $3.4 million of leasehold incentives at December 31, 2019 from the adoption of ASU 2016-02, “Leases (Topic 842)” effective January 1, 2019. Depreciation expense for 2019 and 2018 was $3.0 million and $2.7 million, respectively. Accumulated depreciation was $23.8 million and $20.8 million at December 31, 2019 and 2018, respectively. 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 we do not have variable interests in the Trusts. Therefore, the Trusts are not consolidated in our consolidated financial statements. We are also involved in the normal course of business with variable interest entities primarily as a passive investor in mortgage-backed securities and certain collateralized corporate bank loans issued by third party variable interest entities. The maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the consolidated balance sheets. Losses and Loss Adjustment Expenses Losses and LAE represent the estimated ultimate net cost of all reported and unreported losses incurred through December 31, 2019 and 2018. The reserves for unpaid losses and LAE are estimated using individual case-basis valuations and statistical analyses. These estimates are subject to the effects of trends in loss severity and frequency. Although considerable variability is inherent in such estimates, we believe that the reserves for unpaid losses and LAE are adequate. The estimates are continually reviewed and adjusted as experience develops or new information becomes known. Such adjustments are included in current operations. Recognition of Premium Revenues Insurance premiums are earned pro rata over the terms of the policies. Insurance policy fees are earned as of the effective date of the policy. Upon cancellation, any unearned premium is refunded to the insured. Insurance premiums written include gross policy fees of $8.7 million and $6.5 million for the years ended December 31, 2019 and 2018, respectively. Finance Charges We receive premium installment fees for each direct bill payment from policyholders. Installment fee income is classified as finance charges on the consolidated statement of operations and is recognized as the fee is invoiced. Agent Commissions We pay monthly commissions to agents based on written premium produced, but generally recognize the expense pro rata over the term of the policy. If the policy is cancelled prior to its expiration, the unearned portion of the agent commission is refundable to us. The unearned portion of commissions paid to agents is included in deferred policy acquisition costs. We annually pay a profit sharing commission to our independent agency force based upon the results of the business produced by each agent. We estimate and accrue this liability to commission expense in the year the business is produced. Commission expense is classified as operating expenses in the consolidated statements of operations. 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. Deferred taxes are recognized using the liability method, whereby tax rates are applied to cumulative temporary differences based on when and how they are expected to affect the tax return. Deferred tax assets and liabilities are adjusted for tax rate changes in effect for the year in which these temporary differences are expected to be recovered or settled. Earnings Per Share The computation of earnings per share is based upon the weighted average number of common shares outstanding during the period plus the effect of common shares potentially issuable (in periods in which they have a dilutive effect), primarily from stock options. (See Notes 12 and 14.) Adoption of New Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued updated guidance that allows a reclassification of the stranded tax effects in AOCI resulting from the Tax Cuts and Jobs Act of 2017 (TCJA). Prior guidance required the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that included the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification included the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of TCJA related to items in AOCI. The updated guidance was effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the TCJA related to items remaining in AOCI is recognized or at the beginning of the period of adoption. The Company adopted the updated guidance effective January 1, 2018 and elected to reclassify the income tax effects of the TCJA from AOCI to retained earnings as of January 1, 2018. This reclassification resulted in a decrease in retained earnings of $2.6 million as of January 1, 2018 and an increase in AOCI by the same amount. In March 2017, the FASB issued ASU 2017‑08, “Premium Amortization on Purchased Callable Securities” (Subtopic 310‑20). ASU 2017‑08 is intended to enhance the accounting for amortization of premiums for purchased callable debt securities. The guidance amends the amortization period for certain purchased callable debt securities held at a premium. Securities that contain explicit, noncontingent call features that are callable at fixed prices and on preset dates should shorten the amortization period for the premium to the earliest call date (and if the call option is not exercised, the effective yield is reset using the payment terms of the debt security). The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings. The adoption of ASU 2017‑08 had no impact on our financial results and disclosures. In January 2017, the FASB issued ASU 2017‑01, “Clarifying the Definition of a Business (Topic 715)”. ASU 2017‑01 is intended to assist entities in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017‑01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The adoption of this standard did not have a material impact on our financial condition or results of operations. In January 2016, the FASB issued ASU 2016‑01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (Subtopic 825‑10). ASU 2016‑01 requires equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. ASU 2016‑01 also requires us to assess the ability to realize our deferred tax assets (“DTAs”) related to an available-for-sale debt security in combination with our other DTAs. ASU 2016‑01 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this guidance resulted in the recognition of $17.0 million of net after-tax unrealized gains on equity investments as a cumulative effect adjustment that increased retained earnings as of January 1, 2018 and decreased AOCI by the same amount. The Company elected to report changes in the fair value of equity investments in investment gains (losses) in the Consolidated Statement of Operations. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, ASU 2016-02 modifies current guidance for lessors' accounting. ASU 2016-02 is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. During 2018, the FASB issued several amendments and targeted improvements to ease the application of the standard, including the addition of a transition approach that gives the Company the option of applying the standard at either the beginning of the earliest comparative period presented or the beginning of the period of adoption. We adopted the standard on its effective date of January 1, 2019. We also elected certain practical expedients that allow us not to reassess existing leases under the new guidance. As of December 31, 2019, $16.0 million of right-of-use assets and $17.3 million of lease liabilities for operating leases were included in the other assets and other liabilities line items of the balance sheet, respectively, as a result of the adoption of this update. In August 2016, the FASB issued ASU 2016‑15, “Classification of Certain Cash Receipts and Cash Payments” (Topic 230). ASU 2016‑15 will reduce diversity in practice on how eight specific cash receipts and payments are classified on the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years. The adoption of this new guidance did not have a material impact on our financial results or disclosures. In November 2016, the FASB issued ASU 2016‑18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The purpose of ASU 2016‑18 is to eliminate the diversity in classifying and presenting changes in restricted cash in the statement of cash flows. The new guidance requires restricted cash to be combined with cash and cash equivalents when reconciling the beginning and ending balances of cash on the statement of cash flows, thereby no longer requiring transactions such as transfers between restricted and unrestricted cash to be treated as a cash flow activity. Further, the new guidance requires the nature of the restrictions to be disclosed, as well as a reconciliation between the balance sheet and the statement of cash flows on how restricted and unrestricted cash are segregated. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within that fiscal year, with early adoption permitted. Effective January 1, 2018, we retrospectively adopted this new guidance which did not have a material impact on our financial results or disclosures. In May 2014, the FASB issued ASU 2014‑09, guidance which revises the criteria for revenue recognition. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies the performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs. The guidance is effective for reporting periods beginning after December 15, 2017 and is to be applied retrospectively. Revenue from insurance contracts is excluded from the scope of this new guidance. While insurance contracts are excluded from this guidance, policy fee income, billing and other fees and fee income related to property business written as a cover-holder through a Lloyds Syndicate is subject to this updated guidance. The Company adopted this guidance in the first quarter of 2018 with no material impact on the consolidated financial statements. Recently Issued Accounting Pronouncements In December 2019, the FASB issued updated guidance for the accounting for income taxes. The updated guidance is intended to simplify the accounting for income taxes by removing several exceptions contained in the existing guidance and amending other existing guidance to simplify several other income tax accounting matters. The updated guidance is effective for the quarter ending March 31, 2021. Early adoption is permitted. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financials position or liquidity. On August 28, 2018, the FASB issued ASU 2018-13, “Fair Value Measurement: Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement” (Topic 820), which amends ASC 820 to add, remove, and modify fair value measurement disclosure requirements. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. As the amendments are only disclosure related, our financial statements will not be materially impacted by this update. In January 2017, the FASB issued ASU 2017‑04, “Simplifying the Test for Goodwill Impairment” (Topic 350). ASU 2017‑04 requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company’s results of operations, financial position or liquidity. In June 2016, the FASB issued ASU 2016‑13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016‑13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. As a smaller reporting company, ASU 2016‑13 is effective for fiscal years of the Company beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016‑13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures, but do not anticipate that any potential impact would be material.

We realized gross losses on investments of $0.5 million and $0.7 million during the years ended December 31, 2019 and 2018, respectively, of which $0.1 million was from the sale of securities during the year ended December 31, 2019. Our realized losses during the year ended December 31, 2018 did not include sales from securities. We recorded proceeds from the sale of investment securities of $13.0 million, and $17.7 million during the years ended December 31, 2019 and 2018, respectively. Realized investment gains and losses are recognized in operations on the first in-first out method.

We held a total of 328 debt securities with an unrealized loss, of which 221 were in an unrealized loss position for less than one year and 107 were in an unrealized loss position for a period of one year or greater, as of December 31, 2018. We held a total of 9 equity securities with an unrealized loss, of which 7 were in an unrealized loss position for less than one year and 2 were in an unrealized loss position for a period of one year or greater, as of December 31, 2019. We held a total of 20 equity securities with an unrealized loss, of which 17 were in an unrealized loss position for less than one year and 3 were in an unrealized loss position for a period of one year or greater, as of December 31, 2018. We consider these losses as a temporary decline in value as they are predominately 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 December 31, 2019 were due predominately to normal market and interest rate fluctuations and we see no other indications that the decline in values of these securities is other-than-temporary. Based on evidence gathered through our normal credit evaluation process, we presently expect that all debt securities held in our investment portfolio will be paid in accordance with their contractual terms. Nonetheless, it is at least reasonably possible that the performance of certain issuers of these debt securities will be worse than currently expected resulting in future write-downs within our portfolio of debt securities. Also, as a result of the challenging market conditions, we expect the volatility in the valuation of our equity securities to continue in the foreseeable future. This volatility may lead to changes regarding retention strategies for certain equity 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. Debt Investments: We assess whether we intend to sell, or it is more likely than not that we will be required to sell, a fixed maturity investment before recovery of its amortized cost basis less any current period credit losses. For fixed maturity investments that are considered other-than-temporarily impaired and that we do not intend to sell and will not be required to sell, we separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the investment’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the investment’s fair value and the present value of future expected cash flows is recognized in other comprehensive income. During 2019 we disposed of six previously impaired securities and recognized a realized gain of $4.1 million. During 2018 we sold one previously impaired security with a realized loss of $0.1 million and recognized a change in unrealized gain of $1.8 million on the remaining securities. Equity Investments: On January 1, 2018, we adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 requires equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income each reporting period. As a result of the new standard, equity securities with readily determinable fair values are no longer required to be evaluated for other-than-temporary-impairment. Details regarding the carrying value of the other invested assets portfolio as of December 31, 2019 and 2018 were as follows: December 31, December 31, 2019 2018 Investment Type Equity warrant $ 2,169 $ 1,148 Total other investments $ 2,169 $ 1,148 We acquired this equity warrant in an active market and it entitles us to buy the underlying common stock of a publicly traded company at a fixed exercise price until the expiration date of January 19, 2021. The amortized cost and estimated fair value of debt securities at December 31, 2019 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 $ 107,108 $ 107,605 Due after one year through five years 342,962 345,860 Due after five years through ten years 87,669 88,061 Due after ten years 23,760 24,926 Mortgage-backed 7,999 7,827 $ 569,498 $ 574,279 We have certain of our securities pledged for the benefit of various state insurance departments and reinsurers. These securities are included with our available-for-sale debt securities because we have the ability to trade these securities. We retain the interest earned on these securities. These securities had a carrying value of $28.9 million at December 31, 2019 and a carrying value of $29.5 million at December 31, 2018.

Fair Value

Fair Value [Abstract]
Fair Value	3. Fair Value: ASC 820 defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements 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 common and preferred stock and the equity warrant classified as Other Investments. 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 services. 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, our assets that are measured at fair value on a recurring basis at December 31, 2019 and December 31, 2018 (in thousands). As of December 31, 2019 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 $ — $ 66,600 $ - $ 66,600 Corporate bonds — 300,486 339 300,825 Collateralized corporate bank loans — 115,757 - 115,757 Municipal bonds — 83,270 - 83,270 Mortgage-backed — 7,827 - 7,827 Total debt securities — 573,940 339 574,279 Total equity securities 99,215 — — 99,215 Total other investments 2,169 — — 2,169 Total investments $ 101,384 $ 573,940 $ 339 $ 675,663 As of December 31, 2018 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 $ — $ 48,106 $ — $ 48,106 Corporate bonds — 241,861 291 242,152 Collateralized corporate bank loans — 126,528 — 126,528 Municipal bonds — 115,527 — 115,527 Mortgage-backed — 13,557 — 13,557 Total debt securities — 545,579 291 545,870 Total equity securities 80,896 — — 80,896 Total other investments 1,148 — — 1,148 Total investments $ 82,044 $ 545,579 $ 291 $ 627,914 Due to significant unobservable inputs into the valuation model for one corporate bond as of December 31, 2019 and 2018, we classified this investment as Level 3 in the fair value hierarchy. The corporate bond classified as level 3 in 2019 and 2018 is a convertible senior note and its fair value was estimated by the sum of the bond value using an income approach discounting the scheduled interest and principal payments and the conversion feature utilizing a binomial lattice model. The following table summarizes the changes in fair value for all financial assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the year ended December 31, 2019 and 2018(in thousands). 2019 2018 Beginning balance as of January 1 $ 291 $ 3,757 Sales — — Settlements — (2,925) Purchases — — Issuances — — Total realized/unrealized gains included in net income 48 80 Net gain included in other comprehensive income — — Transfers into Level 3 — — Transfers out of Level 3 — (621) Ending balance as of December 31 $ 339 $ 291 The transfer out of Level 3 into Level 1 during 2018 was due to the conversion of a private equity holding to a preferred stock traded on a public exchange. We account for transfers as they occur.

Acquisitions, Goodwill and Intangible Assets [Abstract]
Acquisitions, Goodwill and Intangible Assets	4. Acquisitions, Goodwill and Intangible Assets: Goodwill is tested for impairment at the reporting unit level (business unit or one level below a business unit) on an annual basis (October 1) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. For purposes of evaluating goodwill for impairment, we have determined that our reporting units are the same as our business units except for the E&S Casualty and Aerospace & Programs business units for which reporting units are at the component level (“one level below”). Our consolidated balance sheet as of December 31, 2019 includes goodwill of acquired businesses of $44.7 million that is assigned to our business units as follows: Commercial Accounts business unit - $2.1 million; Commercial Auto business units - $21.3 million; E&S Casualty business unit - $6.3 million (comprised of $2.6 million for the primary/excess liability and public entity component and $3.7 million for the E&S package component); Aerospace & Programs business unit- $9.7 million (comprised entirely of the general aviation component); and Specialty Personal Lines business unit - $5.3 million. This amount has been recorded as a result of prior business acquisitions accounted for under the acquisition method of accounting. Under ASC 350, “Intangibles- Goodwill and Other,” goodwill is tested for impairment annually. We completed our last annual test for impairment on the first day of the fourth quarter of 2019 and determined that there was no impairment at that time. The income approach to determining fair value computed the projections of the cash flows that the reporting unit was expected to generate converted into a present value equivalent through discounting. Significant assumptions in the income approach model included income projections, discount rates and terminal growth values. The income projections reflected an improved premium rate environment across most of our lines of business that continued throughout 2019. The income projections also included loss and LAE assumptions which reflected recent historical claim trends and the movement towards a more favorable pricing environment. The income projections also included assumptions for expense growth and investment yields which were based on business plans for each of our business units. The discount rate was based on a risk free rate plus a beta adjusted equity risk premium and specific company risk premium. The assumptions were based on historical experience (including factors such as prior year loss reserve development), expectations of future performance (including premium growth rates, premium rate increases and loss costs), expected market conditions and other factors requiring judgment and estimates. While we believe the assumptions used in these models were reasonable, the inherent uncertainty in predicting future performance and market conditions may change over time and influence the outcome of future testing. During 2019 and 2018, we completed the first step prescribed by ASC 350 for testing for impairment and determined that there was no impairment. We have obtained various intangible assets from several acquisitions. The table below details the gross and net carrying amounts of these assets by major category (in thousands): December 31 2019 2018 Gross Carrying Amount: Customer/agent relationships $ 32,177 $ 32,177 Tradename 3,440 3,440 Management agreement 3,232 3,232 Non-compete & employment agreements 4,235 4,235 Insurance licenses 1,300 1,300 Total gross carrying amount 44,384 44,384 Accumulated Amortization: Customer/agent relationships (28,752) (26,515) Tradename (3,078) (2,847) Management agreement (3,232) (3,232) Non-compete & employment agreements (4,235) (4,235) Total accumulated amortization (39,297) (36,829) Total net carrying amount $ 5,087 $ 7,555 Insurance licenses are not amortized because they have an indefinite life. We amortize definite-lived intangible assets straight line over their respective lives. The estimated aggregate amortization expense for definite-lived intangible assets for the next five years is as follows (in thousands): 2020 $ 2,467 2021 $ 503 2022 $ 501 2023 $ 316 2024 $ — The weighted average amortization period for definite-lived intangible assets by major class is as follows: Years Tradename 15 Customer/ agent relationships 15 Management agreement 4 Non-compete agreements 5 The aggregate weighted average period to amortize these assets is approximately 13 years.

Reserves for Unpaid Losses and Loss Adjustment Expenses	6. Reserves for Losses and Loss Adjustment Expenses: Activity in the consolidated reserves for unpaid losses and LAE is summarized as follows (in thousands): 2019 2018 Balance at January 1 $ 527,247 $ 527,100 Less reinsurance recoverable 221,716 154,612 Net balance at January 1 305,531 372,488 Incurred related to: Current year 301,265 250,075 Prior years 60,900 5,953 Total incurred 362,165 256,028 Paid related to: Current year 127,610 90,640 Prior years 192,335 232,345 Total paid 319,945 322,985 Net balance at December 31 347,751 305,531 Plus reinsurance recoverable 272,604 221,716 Balance at December 31 $ 620,355 $ 527,247 The $60.9 million unfavorable net development and $6.0 million unfavorable net development in prior accident years recognized in 2019 and 2018, respectively, represent changes in our loss reserve estimates. In 2019 and 2018, the aggregate loss reserve estimates for prior years were increased to reflect unfavorable loss development when the available information indicated a reasonable likelihood that the ultimate losses would be more than the previous estimates. The unfavorable prior year reserve development during the twelve months ended December 31, 2019 was primarily driven by the continued emergence of increased frequency and severity trends in our primary commercial auto lines of business within our Commercial Auto business unit, which was representative of industry trends and unfavorable development in our general liability lines with our E&S Casualty business unit. The unfavorable prior year reserve development during the twelve months ended December 31, 2018 was primarily driven by the continued emergence of increased frequency and severity trends in our primary commercial auto lines of business within our Commercial Auto business unit, which was representative of industry trends, partially offset by net favorable development in our general liability lines within our E&S Casualty and Commercial Accounts business units. Generally, changes in reserves are caused by variations between actual experience and previous expectations and by reduced emphasis on the Bornhuetter-Ferguson method due to the aging of the accident years. The impact from the unfavorable (favorable) net prior years’ loss development on each reporting segment is presented below: December 31, 2019 2018 Specialty Commercial Segment $ 60,138 $ 16,457 Standard Commercial Segment 726 (8,993) Personal Segment 36 (1,511) Corporate — — Total unfavorable net prior year development $ 60,900 $ 5,953 The following describes the primary factors behind each segment’s prior accident year loss reserve development for the years ended December 31, 2019 and 2018: Year ended December 31, 2019 : · Specialty Commercial Segment. Our Commercial Auto business unit experienced net unfavorable development in the 2017 and prior accident years primarily in the commercial automobile liability line of business, partially offset by favorable development primarily in the commercial automobile line of business in the 2018 accident year. Our E&S Casualty business unit experienced net unfavorable development primarily in our E&S package insurance products in the 2018 and prior accident years. We experienced net favorable development in our E&S Property and Professional Liability business units, partially offset by net unfavorable development in our Aerospace & Programs business unit. · Standard Commercial Segment. Our Commercial Accounts business operating unit experienced net unfavorable development in the 2017, 2016, 2015 and 2013 and prior accident years primarily in the general liability line of business, partially offset by net favorable development primarily in the commercial property line of business in the 2018 and 2014 accident years and net favorable development primarily in the 2015 accident year in the occupational accident line of business. Our former Workers Compensation operating unit experienced net favorable development primarily in the 2015 accident year. · Personal Segment. Net unfavorable development in our Specialty Personal Lines business unit was mostly attributable to the 2018, 2016, 2014 and 2012 and prior accidents years, partially offset by favorable development in the 2017, 2015 and 2013 accident years. Year ended December 31, 2018 : · Specialty Commercial Segment. Our Commercial Auto business unit experienced net unfavorable development in the 2016 and prior accident years , partially offset by favorable development in the 2017 accident year. Our E&S Casualty business unit experienced net favorable development primarily in our E&S package insurance products. We experienced net unfavorable development in our E&S Property, Professional Liability and Aerospace & Programs business units, · Standard Commercial Segment. Our Commercial Accounts business unit experienced net favorable development in the 2016 and prior accident years primarily in the general liability line of business, partially offset by net unfavorable development primarily in the commercial property line of business in the 2017 accident year and net unfavorable development in the 2017 and prior accident years in the occupational accident line of business. Our former Workers Compensation operating unit experienced net favorable development in the 2016 and prior accident years. · Personal Segment. Net favorable development in our Specialty Personal Lines business unit was mostly attributable to the 2013 through 2017 accident years, partially offset by unfavorable development in the 2012 and prior accident years. In the opinion of management, our reserves represent the best estimate of our ultimate liabilities, based on currently known facts, current law, current technology and assumptions considered reasonable where facts are not known. Due to the significant uncertainties and related management judgments, there can be no assurance that future favorable or unfavorable loss development, which may be material, will not occur. Short-Duration Contract Disclosures ASU 2015‑09, “Disclosures about Short-Duration Contracts (Topic 944)", requires insurers to make disclosures about their liability for unpaid claims and claim adjustment expenses for short-duration insurance contracts. These disclosures include tables showing incurred and paid claims development information (net of reinsurance and excluding unallocated loss adjustment expenses) which are disaggregated based on the characteristics of the insurance contracts that the insurer writes and other factors specific to the reporting entity. The information should be disclosed by accident year for the number of years claims typically remain outstanding, but need not be more than 10 years, including a reconciliation of the disaggregated information to the consolidated statement of financial position. We have evaluated the disaggregation criteria and concluded that the basis for our disaggregation of this information is the similar claim duration period of our primary lines of business (certain lines of business have short settlement periods versus long settlement periods). Reserves for Incurred But Not Reported (“IBNR”) Claims Reserves for IBNR claims are based on the estimated ultimate cost of settling claims, including the effects of inflation and other social and economic factors, using past experience adjusted for current trends and any other factors that would modify past experience. We use a variety of statistical and actuarial techniques to analyze current claims costs, including frequency and severity data and prevailing economic, social and legal factors. Each such method has its own set of assumptions and outputs, and each has strengths and weaknesses in different areas. Since no single estimation method is superior to another method in all situations, the methods and assumptions used to project loss reserves will vary by coverage and product. We use what we believe to be the most appropriate set of actuarial methods and assumptions for each product line grouping and coverage. While the loss projection methods may vary by product line and coverage, the general approach for calculating IBNR remains the same: ultimate losses are forecasted first, and that amount is reduced by the amount of cumulative paid claims and case reserves. Reserves established in prior years are adjusted as loss experience develops and new information becomes available. Adjustments to previously estimated reserves are reflected in the results of operations in the year in which they are made. As described above, various actuarial methods are utilized to determine the reserves for losses and LAE recorded in our consolidated balance sheets. Weightings of methods at a detailed level may change from evaluation to evaluation based on a number of observations, measures, and time elements. Methodology for Determining Cumulative Number of Reported Claims A claim file is created when the Company is notified of an actual demand for payment, notified of an event that may lead to a demand for payment or it is determined that a demand for payment could possibly lead to a future demand for payment on another coverage on the same policy or on another policy.The cumulative number of reported claims is predominately measured at the claim level for our Commercial Accounts, Aviation, Personal, Primary Commercial Auto Liability, and certain Programs lines of business and at a coverage level by occurrence for our other lines of business. The Company does not generate claim counts for ceded business. Incurred & Paid Claims Development Disclosures The following tables provide information about incurred and cumulative paid losses and allocated loss adjustment expenses (“ALAE”), net of reinsurance for our primary lines of business with similar claims duration periods. The incurred and paid losses by accident year information presented for all lines of business with similar claim duration periods in the below tables for calendar years prior to 2017 is required supplementary information and is unaudited.

Reinsurance

Reinsurance [Abstract]
Reinsurance	7. 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 December 31, 2019 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 presents our gross and net premiums written and earned and reinsurance recoveries for the last two years (in thousands): 2019 2018 Premium Written : Direct $ 836,797 $ 660,298 Assumed 7,034 2,717 Ceded (347,279) (299,217) $ 496,552 $ 363,798 Premium Earned: Direct $ 748,203 $ 639,437 Assumed 4,763 2,159 Ceded (316,089) (278,509) $ 436,877 $ 363,087 Reinsurance recoveries $ 211,768 $ 199,690 Included in reinsurance recoverable on the consolidated balance sheets are paid loss recoverables of $36.6 million and $29.7 million as of December 31, 2019 and 2018, respectively.

Revolving Credit Facility	8. Revolving Credit Facilities: Our Second Restated Credit Agreement with Frost Bank (“Frost”) dated June 30, 2015, as amended, provided a $15.0 million revolving credit facility (“Facility A”), with a $5.0 million letter of credit sub-facility. The outstanding balance of the Facility A bore interest at a rate equal to the prime rate or LIBOR plus 2.5%, at our election. We paid an annual fee of 0.25% of the average daily unused balance of Facility A and letter of credit fees at the rate of 1.00% per annum. On August 19, 2019, we terminated Facility A. The Second Restated Credit Agreement with Frost also provided a $30.0 million revolving credit facility (“Facility B”), in addition to Facility A. We used Facility B loan proceeds solely for the purpose of making capital contributions to AHIC and HIC. We paid a quarterly fee of 0.25% per annum of the average daily unused balance of Facility B. Facility B bore interest at a rate equal to the prime rate or LIBOR plus 3.00%, at our election. On August 19, 2019, we repaid the $30 million principal balance and accrued interest on Facility B. Upon such repayment, we terminated Facility B.

Senior Unsecured Notes
Senior Unsecured Notes	10. 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 restrict Hallmark’s ability to incur additional indebtedness, pay dividends on or acquire its common stock, or make payments on its other securities or indebtedness if any such action would cause the Company’s debt to capital ratio (calculated in accordance with the indenture) to exceed 35%. Among other things, the indenture also limits Hallmark’s ability to create liens on the stock of, dispose of all or substantially all of the assets of, or permit the merger or consolidation with another entity of any direct or indirect insurance company subsidiary with statutory surplus of at least $50.0 million. As of December 31, 2019, Hallmark was in compliance with all of these covenants.

Earnings per Share	12. Earnings Per Share: We have adopted the provisions of ASC 260, “Earnings Per Share,” requiring presentation of both basic and diluted earnings per share. A reconciliation of the numerators and denominators of the basic and diluted per share calculations is presented below (in thousands, except per share amounts): 2019 2018 Numerator for both basic and diluted earnings per share: Net (loss) income $ (625) $ 10,347 Denominator, basic shares 18,107 18,086 Effect of dilutive securities: Stock-based compensation awards — 115 Denominator, diluted shares 18,107 18,201 Basic (loss) earnings per share: $ (0.03) $ 0.57 Diluted (loss) earnings per share: $ (0.03) $ 0.57 We had 14,157 and 32,164 shares of common stock potentially issuable upon exercise of employee stock options for years ended December 31, 2019 and 2018, respectively, that were excluded from the weighted average number of shares outstanding on a diluted basis because the effect of such options would be anti-dilutive. These instruments, to the extent not previously cancelled or exercised, expire in 2021.

Regulatory Capital Restrictions [Abstract]
Regulatory Capital Restrictions	13. Regulatory Capital Restrictions: Hallmark, as a holding company, is dependent on dividend payments and management fees from its subsidiaries to fund its operating expenses, debt obligations and capital needs, including the ability to pay dividends to its stockholders. Hallmark has never paid dividends on its common stock. Hallmark intends to continue this policy for the foreseeable future in order to retain earnings for development of its business. There are no regulatory or contractual restrictions on the ability of Hallmark to pay dividends other than customary default provisions and the impact of any dividend payment on financial ratio covenants. However, there are restrictions on the ability of Hallmark’s insurance carrier subsidiaries to transfer funds to the holding company. The amount of retained earnings that is unrestricted for the payment of dividends by Hallmark to its shareholders was $35.5 million as of December 31, 2019. AHIC and TBIC, domiciled in Texas, are limited in the payment of dividends to their stockholders in any 12‑month period, without the prior written consent of the Texas Department of Insurance, to the greater of statutory net income for the prior calendar year or 10% of statutory policyholders’ surplus as of the prior year end. HIC and HNIC, both domiciled in Arizona, are limited in the payment of dividends to the lesser of 10% of prior year policyholders’ surplus or prior year’s net income, without prior written approval from the Arizona Department of Insurance. HSIC, domiciled in Oklahoma, is limited in the payment of dividends to the greater of 10% of prior year policyholders’ surplus or prior year’s statutory net income, not including realized capital gains, without prior written approval from the Oklahoma Insurance Department. For all our insurance companies, dividends may only be paid from unassigned surplus funds. During 2020, the aggregate ordinary dividend capacity of these subsidiaries is $22.6 million, of which $15.8 million is available to Hallmark. As a county mutual, dividends from HCM are payable to policyholders. During the years ended December 31, 2019 and 2018 our insurance company subsidiaries paid $15.5 million and $5.5 million, respectively, in dividends to Hallmark. The total restricted net assets of our insurance company subsidiaries as of December 31, 2019, was $227.8 million. The state insurance departments also regulate financial transactions between our insurance subsidiaries and their affiliated companies. Applicable regulations require approval of management fees, expense sharing contracts and similar transactions. Our insurance subsidiaries did not pay management fees to Hallmark and our non-insurance company subsidiaries during 2019 and 2018. Statutory capital and surplus is calculated as statutory assets less statutory liabilities. The various state insurance departments that regulate our insurance company subsidiaries require us to maintain a minimum statutory capital and surplus. As of December 31, 2019 and 2018, our insurance company subsidiaries reported statutory capital and surplus of $254.7 million and $247.0 million, respectively, substantially greater than the minimum requirements for each state. For the years ended December 31, 2019, and 2018, respectively, our insurance company subsidiaries reported a statutory net loss of $10.2 million and statutory net income of $35.9 million, respectively. The National Association of Insurance Commissioners requires property/casualty insurers to file a risk-based capital calculation according to a specified formula. The purpose of the formula is twofold: (1) to assess the adequacy of an insurer’s statutory capital and surplus based upon a variety of factors such as potential risks related to investment portfolio, ceded reinsurance and product mix; and (2) to assist state regulators under the RBC for Insurers Model Act by providing thresholds at which a state commissioner is authorized and expected to take regulatory action. As of December 31, 2019, the adjusted capital under the risk-based capital calculation of each of our insurance company subsidiaries substantially exceeded the minimum requirements.

Share-Based Payment Arrangements [Abstract]
Share-Based Payment Arrangements	14. Share-based Payment Arrangements: Our 2005 Long Term Incentive Plan (“2005 LTIP”) is a stock compensation plan for key employees and non-employee directors that was initially approved by the shareholders on May 26, 2005 and expired by its terms on May 27, 2015. As of December 31, 2019, there were no outstanding incentive stock options and outstanding non-qualified stock options to purchase 14,157 shares of our common stock. The exercise price of all such outstanding stock options is equal to the fair market value of our common stock on the date of grant. Our 2015 Long Term Incentive Plan (“2015 LTIP”) was approved by shareholders on May 29, 2015. There are 2,000,000 shares authorized for issuance under the 2015 LTIP. As of December 31, 2019, restricted stock units representing the right to receive up to 530,236 shares of our common stock were outstanding under the 2015 LTIP. There were no stock option awards granted under the 2015 LTIP as of December 31, 2019. Stock Options: Non-qualified stock options outstanding under the 2005 LTIP vest 100% six months after the date of grant and terminate ten years from the date of grant. The grant of 200,000 non-qualified stock options in 2009 vested in equal annual increments on each of the first seven anniversary dates and was fully exercised prior to termination in 2019. A summary of the status of our stock options as of December 31, 2019 and changes during the year then ended is presented below: Average Remaining Aggregate Number of Weighted Average Contractual Intrinsic Value Shares Exercise Price Term (Years) ($000) Outstanding at January 1, 2019 244,157 $ 6.63 Granted — — Exercised (230,000) $ 6.61 Forfeited or expired — $ — Outstanding at December 31, 2019 14,157 $ 6.99 2.0 $ 150 Exercisable at December 31, 2019 14,157 $ 6.99 2.0 $ 150 The following table details the intrinsic value of options exercised, total cost of share-based payments charged against income before income tax benefit and the amount of related income tax benefit recognized in income for the periods indicated (in thousands): 2019 2018 Intrinsic value of options exercised $ 845 $ 122 Cost of share-based payments (non-cash) $ — $ — Income tax benefit of share-based payments recognized in income $ — $ — As of December 31, 2019, there was no unrecognized compensation cost related to non-vested stock options granted under our plans which is expected to be recognized in the future. The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes option pricing model. Expected volatilities are based on the historical volatility of Hallmark’s and similar companies’ common stock for a period equal to the expected term. The risk-free interest rates for periods within the contractual term of the options are based on rates for U.S. Treasury Notes with maturity dates corresponding to the options expected lives on the dates of grant. Expected term is determined based on the simplified method as we do not have sufficient historical exercise data to provide a basis for estimating the expected term. There were no stock options granted during 2019 or 2018. 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. Restricted stock units vest and, if performance criteria have been satisfied, shares of common stock become issuable on March 31 of the third calendar year following the year of grant. The performance criteria for all restricted stock units require that we achieve certain compound average annual growth rates in book value per share as well as certain average combined ratio percentages over the vesting period in order to receive shares of common stock in amounts ranging from 50% to 150% of the number of restricted stock units granted. 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,” 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 2015, 2016, 2017, 2018 and 2019 was $11.10, $11.41, $10.20, $10.87 and $18.10 per unit, respectively. We incurred compensation expense of $887 thousand and $152 thousand related to restricted stock units during the years ended December 31, 2019 and 2018. We recorded income tax benefit of $186 thousand and $32 thousand related to restricted stock units during the years ended December 31, 2019 and 2018. The following table details the status of our restricted stock units as of and for the years ended December 31, 2019 and 2018: Number of Restricted Stock Units 2019 2018 Nonvested at January 1 338,897 385,779 Granted 97,804 144,059 Vested — (8,198) Forfeited (83,210) (182,743) Nonvested at December 31 353,491 338,897 As of December 31, 2019, there was $2.4 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 $2.4 million of compensation cost related to unvested restricted stock units, of which $1.4 million is expected to be recognized in 2020, $0.8 million is expected to be recognized in 2021 and $0.2 million is expected to be recognized in 2022.

Retirement Plans: Certain employees of the Standard Commercial Segment were participants in a defined cash balance plan covering all full-time employees who had completed at least 1,000 hours of service. This plan was frozen in March 2001 in anticipation of distribution of plan assets to members upon plan termination. All participants were vested when the plan was frozen. The following tables provide detail of the changes in benefit obligations, components of benefit costs, weighted-average assumptions, and plan assets for the retirement plan as of and for the twelve months ending December 31, 2019 and 2018 (in thousands) using a measurement date of December 31. 2019 2018 Assumptions (end of period): Discount rate used in determining benefit obligation 2.98 % 4.05 % Rate of compensation increase N/A N/A Reconciliation of funded status (end of period): Accumulated benefit obligation $ (12,376) $ (11,687) Projected benefit obligation $ (12,376) $ (11,687) Fair value of plan assets 10,988 9,669 Funded status $ (1,388) $ (2,018) Net actuarial loss (4,010) (4,130) Accumulated other comprehensive loss (4,010) (4,130) Prepaid pension cost 2,622 2,112 Net amount recognized as of December 31 $ (1,388) $ (2,018) Changes in projected benefit obligation: Benefit obligation as of beginning of period $ 11,687 $ 12,758 Interest cost 454 424 Actuarial liability loss (gain) 1,083 (628) Benefits paid (848) (867) Benefit obligation as of end of period $ 12,376 $ 11,687 Change in plan assets: Fair value of plan assets as of beginning of period $ 9,669 $ 11,153 Actual return on plan assets (net of expenses) 1,667 (617) Employer contributions 500 — Benefits paid (848) (867) Fair value of plan assets as of end of period $ 10,988 $ 9,669 Net periodic pension cost: Service cost - benefits earned during the period $ — $ — Interest cost on projected benefit obligation 454 424 Expected return on plan assets (607) (694) Recognized actuarial loss 143 106 Net periodic pension cost $ (10) $ (164) Discount rate 4.05 % 3.45 % Expected return on plan assets 6.50 % 6.50 % Rate of compensation increase N/A N/A Estimated future benefit payments by fiscal year (in thousands): 2020 $ 866 2021 $ 874 2022 $ 859 2023 $ 839 2024 $ 828 2025-2029 $ 3,807 As of December 31, 2019, the fair value of the plan assets was composed of cash and cash equivalents of $0.6 million, debt securities of $3.4 million and equity securities of $7.0 million. Our investment objectives are to preserve capital and to achieve long-term growth through a favorable rate of return equal to or greater than 5% over the long-term (60 year) average inflation rate as measured by the consumer price index. The objective of the equity portion of the portfolio is to achieve a return in excess of the Standard & Poor’s 500 index. The objective of the fixed income portion of the portfolio is to add stability, consistency, safety and total return to the total fund portfolio. We prohibit investments in options, futures, precious metals, short sales and purchase on margin. We also restrict the investment in fixed income securities to “A” rated or better by Moody’s or Standard & Poor’s rating services and restrict investments in common stocks to only those that are listed and actively traded on one or more of the major United States stock exchanges, including NASDAQ. We manage to an asset allocation of 45% to 75% in equity securities. An investment in any single stock issue is restricted to 5% of the total portfolio value and 90% of the securities held in mutual or commingled funds must meet the criteria for common stocks. To develop the expected long-term rate of return on assets assumption, we consider the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio. This resulted in the selection of the 6.5% long-term rate of return on assets assumption. The expected return on plan assets uses the fair market value as of December 31, 2019. To develop the discount rate used in determining the benefit obligation we used the Findley AA Pension Discount Curve at the measurement date to match the timing and amounts of projected future benefits. A corridor approach is used to amortize actuarial gains and losses. We are applying the 10% threshold set forth in ASC 715. In addition, since all accrued benefits under the plan are frozen, we are amortizing the unrecognized gains and losses outside of the corridor by the average life expectancy of the plan participants. We expect that we will not be required to make a contribution to the defined benefit cash balance plan during 2020. We expect our 2020 net periodic pension cost to be ($190) thousand, the components of which are interest cost of $355 thousand, expected return on plan assets of ($684) thousand and amortization of actuarial loss of $139 thousand. The following table shows the weighted-average asset allocation for the defined benefit cash balance plan held as of December 31, 2019 and 2018. December 31 2019 2018 Asset Category: Debt securities 31 % 36 % Equity securities 64 % 61 % Other 5 % 3 % Total 100 % 100 % We determine the fair value of our financial instruments based on the fair value hierarchy established in ASC 820. (See Note 3.) The following table presents, for each of the fair value hierarchy levels, our plan assets that are measured at fair value on a recurring basis at December 31, 2019 and December 31, 2018 (in thousands).

We also sponsor a defined contribution plan. Under this plan, employees may contribute a portion of their compensation on a tax-deferred basis, and we may contribute a discretionary amount each year. We contributed $0.7 million and $0.2 million for the years ended December 31, 2019 and 2018.

The TCJA generally repealed the previous two year carry-back and 20 year carry-forward provision for net operating losses and adopted an indefinite carry-forward of net operating losses arising in tax years ending after December 31, 2017. However, the TCJA preserved present law for net operating losses of property/casualty insurance companies. Thus, our net operating losses may be carried-back two years and carried-forward 20 years. On March 27, 2020, the Coronavirus Aid Relief and Economic Security Act (“CARES Act”) was signed into law. The CARES Act grants taxpayers a five-year carry-back period for net operating losses arising in tax years beginning after December 31, 2017 and before January 1, 2021 (i.e. calendar years 2018, 2019 and 2020).

Commitments and Contingencies	18. Commitments and Contingencies: 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 not pay an assessment during 2019 and 2018. As of December 31, 2019 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.

Concentrations of Credit Risk [Abstract]
Concentrations of Credit Risk	20 . Concentrations of Credit Risk: We maintain cash and cash equivalents in accounts with four financial institutions in excess of the amount insured by the Federal Deposit Insurance Corporation. We monitor the financial stability of the depository institutions regularly and do not believe excessive risk of depository institution failure existed at December 31, 2019. We are also subject to credit risk with respect to reinsurers to whom we have ceded underwriting risk. Although a reinsurer is liable for losses to the extent of the coverage it assumes, we remain obligated to our policyholders in the event that the reinsurers do not meet their obligations under the reinsurance agreements. In order to mitigate credit risk to reinsurance companies, we monitor the financial condition of reinsurers on an ongoing basis and review our reinsurance arrangements periodically. Most of our reinsurance recoverable balances as of December 31, 2019 were 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.

Right-of-use assets are included in the other assets line item and lease liabilities are included in the other liabilities line item of the consolidated balance sheet. We also elected certain practical expedients that allow us not to reassess existing leases under the new guidance. 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 which have lease and non-lease components are accounted for as a single lease component. Lease expense is recognized on a straight-line basis over the lease term. The Company’s operating lease obligations predominately pertain to office leases utilized in the operation of our business. Our leases have remaining terms of one to 13 years, some of which include options to extend the leases. The components of lease expense and other lease information as of and during the period ended December 31, 2019 are as follows (in thousands): Twelve Months Ended December 31, 2019 Operating lease cost $ 2,936 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 1,889 Right-of-use assets obtained in exchange for new operating lease liabilities $ — We incurred $26 thousand in short-term lease payments not included in our lease liability during the year ended December 31, 2019.

Subsequent Events
Subsequent Events	22. Subsequent Events : In February, 2020, we made the strategic decision to exit the contract binding line of the primary automobile business marketed by our Commercial Auto business unit as a result of increasing claim severity and limited opportunity for meaningful rate increases. At that time, we began the process of non-renewing policies and placing in-force policies in runoff in accordance with state regulatory guidelines. During 2019, this contract binding business produced $115.0 million in gross premiums written, which represented 56% of the total primary automobile premium volume of our Commercial Auto business unit. On May 5, 2020, a lawsuit styled Schulze v. Hallmark Financial Services, Inc. , et. al (Case No. 3:20-cv-01130) was filed in the U.S. District Court for the Northern District of Texas, Dallas Division. The Company, its Chief Executive Officer and its Chief Financial Officer are named defendants in the lawsuit brought on behalf of a putative class of shareholders who acquired Hallmark securities between March 5, 2019 and March 17, 2020. In general, the complaint alleges that the defendants violated the Securities Exchange Act of 1934 by failing to disclose that (a) the Company lacked effective internal controls over financial reporting related to its reserves for unpaid losses, (b) the Company improperly accounted for reserves for unpaid losses, (c) the Company would be forced to report $63.8 million of prior year net adverse loss development, (d) the Company would exit the contract binding line of its commercial automobile primary insurance business, and (e) the defendants’ positive statements about the Company’s business, operations and prospects were materially misleading and/or lacked a reasonable basis. The court has not yet appointed a lead plaintiff, and defendants’ responsive pleading is not yet due and has not been filed. The litigation is in its initial stages and we are unable to reasonably predict its potential outcome. The Company, however, believes that the lawsuit is without merit and intends to vigorously defend the claims. The Company’s current policy is to expense legal costs as incurred. Historically, the Company has not carried director and officer liability insurance and does not currently hold such a policy. In connection with its normal process for evaluating triggering events, the Company determined that a significant decline in its market capitalization below its stockholders’ equity during the first quarter of 2020 was an event that indicated the impairment of the goodwill and indefinite-lived intangible assets included in its balance sheet. As a result, the Company has taken a $44.7 million charge to goodwill and a $1.3 million charge to indefinite-lived intangible assets as of March 31, 2020.

Accounting Policies [Abstract]
General	General Hallmark Financial Services, Inc. (“Hallmark” and, together with subsidiaries, the “Company”, “we,” “us” or “our”) is an insurance holding company engaged in the sale of property/casualty insurance products to businesses and individuals. Our business involves marketing, distributing, underwriting and servicing our insurance products, as well as providing other insurance related services. We market, distribute, underwrite and service our property/casualty insurance products primarily through business units organized by products and distribution channel. Our business units are supported by our insurance company subsidiaries. Our Commercial Auto business unit offers primary and excess commercial vehicle insurance products and services; our E&S Casualty business unit offers primary and excess liability, excess public entity liability, E&S package and garage liability insurance products and services; our E&S Property business unit offers primary and excess commercial property insurance for both catastrophe and non-catastrophe exposures; our Professional Liability business unit offers healthcare and financial lines professional liability insurance products and services primarily for businesses, medical professionals, medical facilities and senior care facilities; and our Aerospace & Programs business unit offers general aviation and satellite launch property/casualty insurance products and services, as well as certain specialty programs. These products and services were previously reported as the Contract Binding and Specialty Commercial business units. Our Commercial Accounts business unit (f/k/a Standard Commercial P&C business unit) offers package and monoline property/casualty and occupational accident insurance products. Effective June 1, 2016 we ceased marketing new or renewal occupational accident policies. Our former Workers Compensation operating unit specialized in small and middle market workers compensation business. Effective July 1, 2015, we no longer market or retain any risk on new or renewal workers compensation policies. Our Specialty Personal Lines business unit offers non-standard personal automobile and renters insurance products and services. Our insurance company subsidiaries supporting these business units are American Hallmark Insurance Company of Texas (“AHIC”), Hallmark Insurance Company (“HIC”), Hallmark Specialty Insurance Company (“HSIC”), Hallmark County Mutual Insurance Company (“HCM”), Hallmark National Insurance Company (“HNIC”) and Texas Builders Insurance Company (“TBIC”). These business units are segregated into three reportable industry segments for financial accounting purposes. The Specialty Commercial Segment includes our Commercial Auto business unit, E&S Casualty business unit, E&S Property business unit, Professional Liability business unit and Aerospace & Programs business unit. The Standard Commercial Segment consists of the Commercial Accounts business unit and the runoff from our former Workers Compensation operating unit. The Personal Segment consists solely of our Specialty Personal Lines business unit.
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts and operations of Hallmark and its subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) which, as to our insurance company subsidiaries, differ from statutory accounting practices prescribed or permitted for insurance companies by insurance regulatory authorities.
Use of Estimates in the Preparation of the Financial Statements	Use of Estimates in the Preparation of Financial Statements Our preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities at the dates of the financial statements and our reported amounts of revenues and expenses during the reporting periods. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Since future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment may be reflected in the financial statements in future periods. The liability for unpaid claims and claims adjustment expenses and related amounts recoverable from reinsurers represents the most significant estimate in the accompanying financial statements, and any difference between such estimate and actual results could be material. Significant estimates in the accompanying financial statements also include the fair values of investments, deferred policy acquisition cost recoverability, deferred tax asset valuation, and fair value of goodwill and intangible assets.
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: The carrying amounts reported in the balance sheet for these instruments approximate their fair values. Restricted Cash: The carrying amount for restricted cash reported in the balance sheet approximates the fair value. Subordinated debt securities: Our trust preferred securities are reported at carry value of $55.9 million and $55.8 million, and had a fair value of $41.7 million and $45.6 million, as of December 31, 2019 and 2018, respectively, and would be included in Level 3 of the fair value hierarchy if they were reported at fair value. Senior unsecured notes due 2029: Our senior unsecured notes payable due in 2029 had a carry value of $49.1 million and a fair value of $49.8 million as of December 31, 2019. Our senior unsecured notes payable would be included in Level 3 of the fair value hierarchy if they were reported at fair value. For reinsurance balances, premiums receivable, federal income tax recoverable/payable, other assets and other liabilities, the carrying amounts approximate fair value because of the short maturity of such financial instruments.
Investments	Investments Debt securities available for sale are reported at fair value. Unrealized gains and losses are recorded as a component of accumulated other comprehensive income (“AOCI”), net of related tax effects. Debt securities that are determined to have other-than-temporary impairment are recognized as a loss on investments in the consolidated statements of operations for the portion that is related to credit deterioration with the remaining portion recognized in other comprehensive income. Debt security premiums and discounts are amortized into earnings using the effective interest method. Maturities of debt securities and sales of equity securities are recorded in receivable for securities until the cash is settled. Purchases of debt and equity securities are recorded in payable for securities until the cash is settled. Equity securities are reported at fair value. On January 1, 2018, we adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 requires equity securities to be measured at fair value with changes in fair value recognized in net income. As a result of the new standard, equity securities with readily determinable fair values are no longer required to be evaluated for other-than-temporary impairment. Prior to the adoption of ASU 2016-01, unrealized gains and losses on equity securities were recorded as a component of AOCI, net of related tax effects. Other investments consist of an equity warrant which is reported at fair value. Unrealized gains and losses are reported in the statement of operations as a component of net realized gains (losses). Realized investment gains and losses are recognized in operations on the first in-first out method.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and highly liquid investments with an original maturity of three months or less.
Restricted Cash	Restricted Cash Restricted cash represents amounts required to be set aside by a contractual agreement with a third-party insurer and amounts pledged for the benefit of various state insurance departments.
Premiums Receivable	Premiums Receivable Premiums receivable represent amounts due from policyholders or independent agents for premiums written and uncollected. These balances are carried at net realizable value.
Reinsurance	Reinsurance We are routinely involved in reinsurance transactions with other companies. Reinsurance premiums, losses and loss adjustment expenses (“LAE”) are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. (See Note 7.)
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs Policy acquisition costs (mainly direct commission, premium taxes, underwriting, marketing expenses and ceding commission) that are directly related to the successful acquisition of new and renewal insurance contracts are deferred and recognized to operations over periods in which the related premiums are earned. The method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. In determining estimated realizable value, the computation gives effect to the premium to be earned, expected investment income, losses and LAE and certain other costs expected to be incurred as the premiums are earned. If the computation results in an estimated net realizable value less than zero, a liability will be accrued for the premium deficiency. During 2019 and 2018, we deferred ($156.8) million and ($124.5) million of direct policy acquisition costs and amortized $141.0 million and $120.3 million of deferred direct policy acquisition costs, respectively. During 2019 and 2018, we deferred $160.8 million and $88.8 million of ceding commission acquisition costs and amortized ($153.7) million and ($82.9) million of deferred ceding commission acquisition costs, respectively. Therefore, the net amortization (deferrals) of policy acquisition costs were ($8.7) million and $1.7 million for 2019 and 2018, respectively.
Business Combinations	Business Combinations We account for business combinations using the acquisition method of accounting pursuant to Accounting Standards Codification (“ASC”) 805, “Business Combinations.” The base cash purchase price plus the estimated fair value of any non-cash or contingent consideration given for an acquired business is allocated to the assets acquired (including identified intangible assets) and liabilities assumed based on the estimated fair values of such assets and liabilities. The excess of the fair value of the total consideration given for an acquired business over the aggregate net fair values assigned to the assets acquired and liabilities assumed is recorded as goodwill. Contingent consideration is recognized as a liability at fair value as of the acquisition date with subsequent fair value adjustments recorded in the consolidated statements of operations. The valuation of contingent consideration requires assumptions regarding anticipated cash flows, probabilities of cash flows, discount rates and other factors. Significant judgment is employed in determining the propriety of these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions, can materially impact the amount of contingent consideration expense we record in any given period. Indirect and general expenses related to business combinations are expensed as incurred.
Goodwill and Intangible Assets, net	Goodwill and Intangible Assets, net We account for our goodwill and intangible assets according to ASC 350, “Intangibles – Goodwill and Other.” Under ASC 350, intangible assets with a finite life are amortized over the estimated useful life of the asset. Goodwill and intangible assets with an indefinite useful life are not amortized. Goodwill and intangible assets are tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. For goodwill, we may perform a qualitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. The first step of the quantitative test is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill (“Step 1”). If the fair value of a reporting unit exceeds its carrying value amount, goodwill of the reporting unit is not considered to have a potential impairment and the second step is not necessary. However, if the carrying amount of the reporting unit exceeds its fair value, the second step (“Step 2”) is performed to determine if goodwill is impaired and to measure the amount of impairment loss to recognize, if any. Step 2 compares the implied fair value of goodwill with the carrying amount of goodwill. If the implied value of goodwill is less than the carrying amount of goodwill, it is written down to its fair value with a corresponding expense reflected in the Consolidated Statements of Income. The implied goodwill is calculated based on a hypothetical purchase price allocation, similar to the requirements in the accounting guidance for business combinations, whereby the implied fair value of the reporting unit is allocated to the fair value of the assets and liabilities of the reporting unit. We have elected to perform our goodwill impairment test on the first day of the fourth quarter, October 1, of each year.
Leases	Leases We have several leases, primarily for office facilities and computer equipment, which expire in various years through 2032. Some of these leases include rent escalation provisions throughout the term of the lease. We expense the average annual cost of the lease with the difference to the actual rent invoices recorded as a right of use asset and a lease obligation. Right of use assets and lease obligations are classified in other assets and in accounts payable and other accrued expenses, respectively, on our consolidated balance sheets.
Property and Equipment	Property and Equipment Property and equipment (including leasehold improvements), aggregating $34.6 million and $27.0 million, at December 31, 2019 and 2018, respectively, which is included in other assets, is recorded at cost and is depreciated using the straight-line method over the estimated useful lives of the assets (three to ten years) or the life of the lease, whichever is shorter. Property and equipment includes $3.4 million of leasehold incentives at December 31, 2019 from the adoption of ASU 2016-02, “Leases (Topic 842)” effective January 1, 2019. Depreciation expense for 2019 and 2018 was $3.0 million and $2.7 million, respectively. Accumulated depreciation was $23.8 million and $20.8 million at December 31, 2019 and 2018, respectively.
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 we do not have variable interests in the Trusts. Therefore, the Trusts are not consolidated in our consolidated financial statements. We are also involved in the normal course of business with variable interest entities primarily as a passive investor in mortgage-backed securities and certain collateralized corporate bank loans issued by third party variable interest entities. The maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the consolidated balance sheets.
Losses and Loss Adjustment Expenses	Losses and Loss Adjustment Expenses Losses and LAE represent the estimated ultimate net cost of all reported and unreported losses incurred through December 31, 2019 and 2018. The reserves for unpaid losses and LAE are estimated using individual case-basis valuations and statistical analyses. These estimates are subject to the effects of trends in loss severity and frequency. Although considerable variability is inherent in such estimates, we believe that the reserves for unpaid losses and LAE are adequate. The estimates are continually reviewed and adjusted as experience develops or new information becomes known. Such adjustments are included in current operations.
Recognition of Premium Revenues	Recognition of Premium Revenues Insurance premiums are earned pro rata over the terms of the policies. Insurance policy fees are earned as of the effective date of the policy. Upon cancellation, any unearned premium is refunded to the insured. Insurance premiums written include gross policy fees of $8.7 million and $6.5 million for the years ended December 31, 2019 and 2018, respectively.
Finance Charges	Finance Charges We receive premium installment fees for each direct bill payment from policyholders. Installment fee income is classified as finance charges on the consolidated statement of operations and is recognized as the fee is invoiced.
Agent Commissions	Agent Commissions We pay monthly commissions to agents based on written premium produced, but generally recognize the expense pro rata over the term of the policy. If the policy is cancelled prior to its expiration, the unearned portion of the agent commission is refundable to us. The unearned portion of commissions paid to agents is included in deferred policy acquisition costs. We annually pay a profit sharing commission to our independent agency force based upon the results of the business produced by each agent. We estimate and accrue this liability to commission expense in the year the business is produced. Commission expense is classified as operating expenses in the consolidated statements of operations.
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. Deferred taxes are recognized using the liability method, whereby tax rates are applied to cumulative temporary differences based on when and how they are expected to affect the tax return. Deferred tax assets and liabilities are adjusted for tax rate changes in effect for the year in which these temporary differences are expected to be recovered or settled.
Earnings Per Share	Earnings Per Share The computation of earnings per share is based upon the weighted average number of common shares outstanding during the period plus the effect of common shares potentially issuable (in periods in which they have a dilutive effect), primarily from stock options. (See Notes 12 and 14.)
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued updated guidance that allows a reclassification of the stranded tax effects in AOCI resulting from the Tax Cuts and Jobs Act of 2017 (TCJA). Prior guidance required the effect of a change in tax laws or rates on deferred tax balances to be reported in income from continuing operations in the accounting period that included the period of enactment, even if the related income tax effects were originally charged or credited directly to AOCI. The amount of the reclassification included the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of the enactment of TCJA related to items in AOCI. The updated guidance was effective for reporting periods beginning after December 15, 2018 and is to be applied retrospectively to each period in which the effect of the TCJA related to items remaining in AOCI is recognized or at the beginning of the period of adoption. The Company adopted the updated guidance effective January 1, 2018 and elected to reclassify the income tax effects of the TCJA from AOCI to retained earnings as of January 1, 2018. This reclassification resulted in a decrease in retained earnings of $2.6 million as of January 1, 2018 and an increase in AOCI by the same amount. In March 2017, the FASB issued ASU 2017‑08, “Premium Amortization on Purchased Callable Securities” (Subtopic 310‑20). ASU 2017‑08 is intended to enhance the accounting for amortization of premiums for purchased callable debt securities. The guidance amends the amortization period for certain purchased callable debt securities held at a premium. Securities that contain explicit, noncontingent call features that are callable at fixed prices and on preset dates should shorten the amortization period for the premium to the earliest call date (and if the call option is not exercised, the effective yield is reset using the payment terms of the debt security). The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings. The adoption of ASU 2017‑08 had no impact on our financial results and disclosures. In January 2017, the FASB issued ASU 2017‑01, “Clarifying the Definition of a Business (Topic 715)”. ASU 2017‑01 is intended to assist entities in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017‑01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The adoption of this standard did not have a material impact on our financial condition or results of operations. In January 2016, the FASB issued ASU 2016‑01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (Subtopic 825‑10). ASU 2016‑01 requires equity investments that are not consolidated or accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. ASU 2016‑01 also requires us to assess the ability to realize our deferred tax assets (“DTAs”) related to an available-for-sale debt security in combination with our other DTAs. ASU 2016‑01 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this guidance resulted in the recognition of $17.0 million of net after-tax unrealized gains on equity investments as a cumulative effect adjustment that increased retained earnings as of January 1, 2018 and decreased AOCI by the same amount. The Company elected to report changes in the fair value of equity investments in investment gains (losses) in the Consolidated Statement of Operations. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Additionally, ASU 2016-02 modifies current guidance for lessors' accounting. ASU 2016-02 is effective for interim and annual reporting periods beginning on or after January 1, 2019, with early adoption permitted. During 2018, the FASB issued several amendments and targeted improvements to ease the application of the standard, including the addition of a transition approach that gives the Company the option of applying the standard at either the beginning of the earliest comparative period presented or the beginning of the period of adoption. We adopted the standard on its effective date of January 1, 2019. We also elected certain practical expedients that allow us not to reassess existing leases under the new guidance. As of December 31, 2019, $16.0 million of right-of-use assets and $17.3 million of lease liabilities for operating leases were included in the other assets and other liabilities line items of the balance sheet, respectively, as a result of the adoption of this update. In August 2016, the FASB issued ASU 2016‑15, “Classification of Certain Cash Receipts and Cash Payments” (Topic 230). ASU 2016‑15 will reduce diversity in practice on how eight specific cash receipts and payments are classified on the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years. The adoption of this new guidance did not have a material impact on our financial results or disclosures. In November 2016, the FASB issued ASU 2016‑18, “Statement of Cash Flows (Topic 230): Restricted Cash.” The purpose of ASU 2016‑18 is to eliminate the diversity in classifying and presenting changes in restricted cash in the statement of cash flows. The new guidance requires restricted cash to be combined with cash and cash equivalents when reconciling the beginning and ending balances of cash on the statement of cash flows, thereby no longer requiring transactions such as transfers between restricted and unrestricted cash to be treated as a cash flow activity. Further, the new guidance requires the nature of the restrictions to be disclosed, as well as a reconciliation between the balance sheet and the statement of cash flows on how restricted and unrestricted cash are segregated. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within that fiscal year, with early adoption permitted. Effective January 1, 2018, we retrospectively adopted this new guidance which did not have a material impact on our financial results or disclosures. In May 2014, the FASB issued ASU 2014‑09, guidance which revises the criteria for revenue recognition. Under the guidance, the transaction price is attributed to underlying performance obligations in the contract and revenue is recognized as the entity satisfies the performance obligations and transfers control of a good or service to the customer. Incremental costs of obtaining a contract may be capitalized to the extent the entity expects to recover those costs. The guidance is effective for reporting periods beginning after December 15, 2017 and is to be applied retrospectively. Revenue from insurance contracts is excluded from the scope of this new guidance. While insurance contracts are excluded from this guidance, policy fee income, billing and other fees and fee income related to property business written as a cover-holder through a Lloyds Syndicate is subject to this updated guidance. The Company adopted this guidance in the first quarter of 2018 with no material impact on the consolidated financial statements. Recently Issued Accounting Pronouncements In December 2019, the FASB issued updated guidance for the accounting for income taxes. The updated guidance is intended to simplify the accounting for income taxes by removing several exceptions contained in the existing guidance and amending other existing guidance to simplify several other income tax accounting matters. The updated guidance is effective for the quarter ending March 31, 2021. Early adoption is permitted. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financials position or liquidity. On August 28, 2018, the FASB issued ASU 2018-13, “Fair Value Measurement: Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement” (Topic 820), which amends ASC 820 to add, remove, and modify fair value measurement disclosure requirements. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. As the amendments are only disclosure related, our financial statements will not be materially impacted by this update. In January 2017, the FASB issued ASU 2017‑04, “Simplifying the Test for Goodwill Impairment” (Topic 350). ASU 2017‑04 requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material impact on the Company’s results of operations, financial position or liquidity. In June 2016, the FASB issued ASU 2016‑13, “Measurement of Credit Losses on Financial Instruments” (Topic 326). ASU 2016‑13 requires organizations to estimate credit losses on certain types of financial instruments, including receivables and available-for-sale debt securities, by introducing an approach based on expected losses. The expected loss approach will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. As a smaller reporting company, ASU 2016‑13 is effective for fiscal years of the Company beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016‑13 requires a modified retrospective transition method and early adoption is permitted. We are currently evaluating the impact that the adoption of this standard will have on our financial results and disclosures, but do not anticipate that any potential impact would be material.
