Accounting Policies [Abstract]
Accounting Policies	1. Accounting Policies: 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, until exited during 2020, satellite launch property/casualty insurance products and services, as well as certain specialty programs. Our Commercial Accounts 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 $55.9 million, and had a fair value of $26.6 million and $41.7 million, as of December 31, 2020 and 2019, 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 $49.1 million and a fair value of $54.3 million and $49.8 million, as of December 31, 2020 and 2019, respectively. 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 with changes in fair value recognized in net income. Equity securities with readily determinable fair values are not required to be evaluated for other-than-temporary impairment. Other investments as of December 31, 2019 consisted of an equity warrant which was 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 2020 and 2019, we deferred ($152.7) million and ($156.8) million of direct policy acquisition costs and amortized $165.6 million and $141.0 million of deferred direct policy acquisition costs, respectively. During 2020 and 2019, we deferred $79.0 million and $160.8 million of ceding commission acquisition costs and amortized ($86.7) million and ($153.7) million of deferred ceding commission acquisition costs, respectively. Therefore, the net amortization (deferrals) of policy acquisition costs were $5.2 million and ($8.7) million for 2020 and 2019, respectively. 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 quantitative impairment test requires an impairment loss 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). We have elected to perform our goodwill impairment test on the first day of the fourth quarter, October 1, of each year. In connection with our normal process for evaluating impairment triggering events, during the first quarter of 2020 we determined that a significant decline in market capitalization below the Company’s stockholders’ equity indicated the impairment of the goodwill and indefinite-lived intangible assets included on the balance sheet. As a result, the Company took a $44.7 million charge to goodwill and a $1.3 million charge to indefinite-lived intangible assets during the first quarter of 2020. Consequently, as of December 31, 2020 there was no goodwill reported on our consolidated balance sheet. 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. (see Note 21) Property and Equipment Property and equipment (including leasehold improvements), aggregating $36.3 million and $34.6 million, at December 31, 2020 and 2019, 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 $2.9million and $3.4 million of leasehold incentives at December 31, 2020 and 2019, respectively, from the adoption of ASU 2016-02, “Leases (Topic 842)” effective January 1, 2019. Depreciation expense for 2020 and 2019 was $3.3 million and $3.0 million, respectively. Accumulated depreciation was $27.1 million and $23.8 million at December 31, 2020 and 2019, respectively. Under ASC 360, “Impairment or disposal of long-lived assets,” property and equipment is tested for impairment annually 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 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, 2020 and 2019. 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 $7.2 million and $8.7 million for the years ended December 31, 2020 and 2019, 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 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. Since the amendments were only disclosure related, our financial statements were not 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 this guidance did not have a material effect on the Company’s results of operations, financials position or liquidity. 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 gave 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, 2020, $14.0 million of right-of-use assets and $15.9 million of lease liabilities for operating leases were included in the other assets other liabilities Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform In December 2019, the FASB issued updated guidance for 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. 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 held a total of 61 debt securities with an unrealized loss, of which 41 were in an unrealized loss position for less than one year and 20 were in an unrealized loss position for a period of one year or greater, as of December 31, 2019. We held a total of 13 equity securities with an unrealized loss, of which six were in an unrealized loss position for less than one year and seven were in an unrealized loss position for a period of one year or greater, as of December 31, 2020. We held a total of nine equity securities with an unrealized loss, of which seven were in an unrealized loss position for less than one year and two were in an unrealized loss position for a period of one year or greater, as of December 31, 2019. We consider these losses as a temporary decline in value as they are on securities that we do not intend to sell and do not believe we will be required to sell prior to recovery of our amortized cost basis. The gross unrealized losses on the debt security positions at December 31, 2020 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. We complete a detailed analysis each quarter to assess whether any decline in the fair value of any debt security below cost is deemed other-than-temporary. All debt securities with an unrealized loss are reviewed. We recognize an impairment loss when a debt security’s value declines below cost, adjusted for accretion, amortization and previous other-than-temporary impairments and it is determined that the decline is other-than-temporary. We recognized $1.7 million of other-than-temporary impairment on debt securities during 2020. We did not recognize an impairment loss during 2019. 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 2020 we disposed of one previously impaired security and recognized no gain or loss on disposal. During 2019 we disposed of six previously impaired securities and recognized a realized gain of $4.1 million. Equity Investments: Equity investments that are not consolidated or accounted for under the equity method of accounting are measured at fair value with changes in fair value recognized in net income each reporting period. Equity securities with readily determinable fair values are not required to be evaluated for other-than-temporary-impairment. Details regarding the carrying value of the other invested assets portfolio as of December 31, 2020 and 2019 were as follows: December 31, December 31, 2020 2019 Investment Type Equity warrant $ — $ 2,169 Total other investments $ — $ 2,169 We acquired this equity warrant in an active market and disposed of it during the fourth quarter of 2020. It entitled 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, 2020 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 $ 255,768 $ 257,246 Due after one year through five years 200,343 203,625 Due after five years through ten years 28,632 28,363 Due after ten years 12,665 13,202 Mortgage-backed 4,759 4,843 $ 502,167 $ 507,279 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 $29.7 million at December 31, 2020 and a carrying value of $28.9 million at December 31, 2019.

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, 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 during 2020 or 2019. 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, 2020 and December 31, 2019 (in thousands).

The corporate bond classified as level 3 in 2020 and 2019 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, 2020 and 2019 (in thousands). 2020 2019 Beginning balance as of January 1 $ 339 $ 291 Sales — — Settlements — — Purchases — — Issuances — — Total realized/unrealized gains included in net income 9 48 Net gain included in other comprehensive income — — Transfers into Level 3 — — Transfers out of Level 3 — — Ending balance as of December 31 $ 348 $ 339 There were no transfers into or out of Level 3 during the years ended December 31, 2020 or 2019.

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 included goodwill of acquired businesses of $44.7 million that was 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 had 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. In connection with our normal process for evaluating impairment triggering events, during the first quarter of 2020 we determined that a significant decline in our market capitalization below our stockholders’ equity indicated the impairment of goodwill and indefinite-lived intangible assets included in our balance sheet. As a result, we took a $44.7 million charge to goodwill and a $1.3 million charge to indefinite-lived intangible assets during the first quarter of 2020. As a result, as of December 31, 2020 there was no goodwill or During 2019, 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 2020 2019 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 Total gross carrying amount 43,084 44,384 Accumulated Amortization: Customer/agent relationships (30,990) (28,752) Tradename (3,305) (3,078) Management agreement (3,232) (3,232) Non-compete & employment agreements (4,235) (4,235) Total accumulated amortization (41,762) (39,297) Total net carrying amount $ 1,322 $ 5,087 We amortize definite-lived intangible assets straight line over their respective lives.

In 2020 and 2019, 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, 2020 was primarily driven by the continued emergence of increased frequency and severity trends in our primary commercial automobile lines of business within our Commercial Auto business unit, which was representative of industry trends, as well as unfavorable development in our general liability lines within our E&S Casualty business unit and our Standard Commercial Segment, as well as our personal automobile liability line in our Specialty Personal Lines business unit. The unfavorable prior year reserve development during the twelve months ended December 31, 2019 was primarily driven by 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, as well as unfavorable development in our general liability lines within our E&S Casualty business unit. 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, 2020 2019 Specialty Commercial Segment $ 45,808 $ 60,138 Standard Commercial Segment 3,357 726 Personal Segment 9,123 36 Corporate — — Total unfavorable net prior year development $ 58,288 $ 60,900 The following describes the primary factors behind each segment’s prior accident year loss reserve development for the years ended December 31, 2020 and 2019: Year ended December 31, 2020 : ● Specialty Commercial Segment. Our Commercial Auto business unit experienced net unfavorable development in the 2018 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 2019 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, partially offset by favorable development in the 2019 accident year. We experienced net favorable development in our E&S Property and Aerospace & Programs business units, partially offset by net unfavorable development in our Professional Liability. ● Standard Commercial Segment. Our Commercial Accounts business operating unit experienced net unfavorable development in the 2018 and prior accident years primarily in the general liability line of business, partially offset by net favorable development primarily in the commercial property and commercial automobile liability lines of business in the 2019 accident year and net favorable development primarily in the 2017 accident year in the occupational accident line of business. Our former Workers Compensation operating unit experienced net favorable development primarily in the 2014 and prior accident years. ● 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, 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. Reserves for unpaid losses and LAE represent management’s 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 2016 is required supplementary information and is unaudited. The following tables also include IBNR reserves plus expected development on reported claims and the cumulative number of reported claims as of December 31, 2020 ($ in thousands): Commercial Auto

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, 2020 and 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. The following table presents our gross and net premiums written and earned and reinsurance recoveries for the last two years (in thousands): 2020 2019 Premium Written : Direct $ 734,800 $ 836,797 Assumed 8,568 7,034 Ceded (304,395) (347,279) Net premiums written $ 438,973 $ 496,552 Premium Earned: Direct $ 803,034 $ 748,203 Assumed 8,454 4,763 Ceded (329,690) (316,089) Net premiums earned $ 481,798 $ 436,877 Reinsurance recoveries $ 260,826 $ 211,768 Included in reinsurance recoverable on the consolidated balance sheets are paid loss recoverables of $55.6 million and $36.6 million as of December 31, 2020 and 2019, respectively. Loss Portfolio Transfer On July 16, 2020, AHIC, HIC, HSIC, HCM and HNIC (collectively, the “Hallmark Insurers”), entered into a Loss Portfolio Transfer Reinsurance Contract to be effective as of January 1, 2020 (the “LPT Contract”) with DARAG Bermuda Ltd. (“DARAG Bermuda”) and DARAG Insurance (Guernsey) Limited (“DARAG Guernsey” and, collectively, the “Reinsurers”). The Hallmark LPT Contract was consummated on July 31, 2020. The Company recorded a $21.7 million pre-tax loss during the third quarter of 2020 attributable to the closing of the LPT Contract. Pursuant to the LPT Contract, (a) the Hallmark Insurers ceded to the Reinsurers all existing and future claims for losses occurring on or prior to December 31, 2019 on the binding primary commercial automobile liability insurance policies and the brokerage primary commercial automobile liability insurance policies issued by the Hallmark Insurers (the “Subject Business”) up to an aggregate limit of $240.0 million, with (i) the first layer of $151.2 million in reinsurance provided by DARAG Bermuda, (ii) the Hallmark Insurers retaining a loss corridor of the next $24.9 million in losses on the Subject Business, (iii) DARAG Bermuda reinsuring a second layer of $27.8 million above the first layer and the Hallmark Insurers’ loss corridor, and (iv) DARAG Guernsey reinsuring the top layer of $36.1 million in losses on the Subject Business, in each case net of third-party reinsurance and other recoveries; (b) the Hallmark Insurers will continue to manage and retain the benefit of other third-party reinsurance on the Subject Business; and (c) the Hallmark Insurers paid the Reinsurers a net reinsurance premium of $92.6 million. In connection with the closing, the parties also entered into a Services Agreement and a Trust Agreement. Pursuant to the Services Agreement, DARAG Bermuda assumed responsibility for certain administrative services, including claims handling, for the Subject Business. Pursuant to the Trust Agreement, the Reinsurers made initial cash deposits in the aggregate amount of $96.7 million into collateral trust accounts with The Bank of New York Mellon, as trustee, to be held as security for the Reinsurers’ obligations to the Hallmark Insurers under the LPT Contract. As of December 31, 2020, the ultimate incurred losses were $177.6 million or $1.5 million in excess of the Hallmark Insurers’ loss corridor. Our reinsurance recoverables of $490.2 million include $63.7 million related to the LPT as of December 31, 2020.

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	9. 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 certain covenants which, among other things, restrict Hallmark’s ability to incur additional indebtedness, make certain payments, create liens on the stock of certain subsidiaries, dispose of certain assets, or merge or consolidate with other entities. The terms of the indenture prohibits payments or other distributions on any security of the Company that ranks junior to the Notes when the Company’s debt to capital ratio (as defined in the indenture) is greater than 35%. The Company’s debt to capital ratio was 38% as of December 31, 2020.

Subordinated Debt Securities [Abstract]
Subordinated Debt Securities	10. Subordinated Debt Securities: We issued trust preferred securities through Trust I and Trust II. These Delaware statutory trusts are sponsored and wholly-owned by Hallmark and each was created solely for the purpose of issuing the trust preferred securities. Each trust pays dividends on its preferred securities at the same rate each quarter as interest is paid on the junior subordinated debt securities. Under the terms of the trust subordinated debt securities, we pay interest only each quarter and the principal of each note at maturity. The subordinated debt securities of each trust are uncollateralized and do not require maintenance of minimum financial covenants. Each trust pays dividends on its preferred securities at the same rate each quarter as interest is paid on the junior subordinated debt securities. Under the terms of the trust subordinated debt securities, we pay interest only each quarter and the principal of each note at maturity. We may elect to defer payments of interest on the trust subordinated debt securities by extending the interest payment period for up to 20 consecutive quarterly periods. During any such extension period, interest continues to accrue on the trust subordinated debt securities, as well as interest on such accrued interest. In order to maintain compliance with the terms of our senior unsecured Notes, we have elected to defer payment of interest on the trust subordinated securities until our debt to capital ratio (as defined in the indenture governing the Notes) is less than 35%. The subordinated debt securities of each trust are uncollateralized and do not require maintenance of minimum financial covenants. The following table summarizes the nature and terms of the junior subordinated debt and trust preferred securities: Hallmark Hallmark Statutory Statutory Trust I Trust II Issue date June 21, 2005 August 23, 2007 Principal amount of trust preferred securities $ 30,000 $ 25,000 Principal amount of junior subordinated debt securities $ 30,928 $ 25,774 Maturity date of junior subordinated debt securities June 15, 2035 September 15, 2037 Trust common stock $ 928 $ 774 Interest rate, per annum Three Month LIBOR + 3.25% Three Month LIBOR + 2.90% Current interest rate at December 31, 2020 3.47% 3.12%

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 $16.8 million as of December 31, 2020. 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 2021, the aggregate ordinary dividend capacity of these subsidiaries is $22.5 million, of which $15.0 million is available to Hallmark. As a county mutual, dividends from HCM are payable to policyholders. During the years ended December 31, 2020 and 2019 our insurance company subsidiaries paid $12.0 million and $15.5 million, respectively, in dividends to Hallmark. The total restricted net assets of our insurance company subsidiaries as of December 31, 2020, was $154.2 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 paid $3.0 million in management fees to Hallmark and our non-insurance subsidiaries during 2020. Our insurance subsidiaries did not pay management fees to Hallmark and our non-insurance company subsidiaries during 2019. 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, 2020 and 2019, our insurance company subsidiaries reported statutory capital and surplus of $211.6 million and $254.7 million, respectively, substantially greater than the minimum requirements for each state. For the years ended December 31, 2020, and 2019, respectively, our insurance company subsidiaries reported a statutory net loss of $10.1 million and $10.2 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, 2020, 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: 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, 2020, 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, 2020, 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 outstanding stock option awards under the 2015 LTIP as of December 31, 2020. 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, 2020 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, 2020 14,157 $ 6.99 Granted — — Exercised — $ — Forfeited or expired — $ — Outstanding at December 31, 2020 14,157 $ 6.99 1.0 $ — Exercisable at December 31, 2020 14,157 $ 6.99 1.0 $ — 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): 2020 2019 Intrinsic value of options exercised $ — $ 845 Cost of share-based payments (non-cash) $ — $ — Income tax benefit of share-based payments recognized in income $ — $ — As of December 31, 2020, 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 2020 or 2019. 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 2017, 2018 and 2019 was $10.20, $10.87 and $18.10 per unit, respectively. We incurred compensation expense (benefit) of ($400) thousand and $887 thousand related to restricted stock units during the years ended December 31, 2020 and 2019. We recorded income tax benefit (expense) of ($84) thousand and $186 thousand related to restricted stock units during the years ended December 31, 2020 and 2019. The following table details the status of our restricted stock units as of and for the years ended December 31, 2020 and 2019: Number of Restricted Stock Units 2020 2019 Nonvested at January 1 353,491 338,897 Granted — 97,804 Vested (19,065) — Forfeited (105,599) (83,210) Nonvested at December 31 228,827 353,491 As of December 31, 2020, there was $1.0 million of unrecognized grant date compensation cost related to unvested restricted stock units assuming compensation cost accrual at target achievement level. Based on the current performance estimate, we expect to recognize $0.3 million of compensation cost related to unvested restricted stock units, of which $0.2 million is expected to be recognized in 2021 and $0.1 million is expected to be recognized in 2022.

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, 2020. 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 2021. We expect our 2021 periodic pension cost to be $(265) thousand, the components of which are interest cost of $271 thousand, expected return on plan assets of ($709) thousand and amortization of actuarial loss of $173 thousand. The following table shows the weighted-average asset allocation for the defined benefit cash balance plan held as of December 31, 2020 and 2019. December 31 2020 2019 Asset Category: Debt securities 25 % 31 % Equity securities 70 % 64 % Other 5 % 5 % Total 100 % 100 % We determine the fair value of our financial instruments based on the fair value hierarchy established in ASC 820.

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 did not contribute during the year ended December 31, 2020. We contributed $0.7 million for the year ended December 31, 2019.

The Tax Cuts and Jobs Act of 2017 (“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: 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 “ Schulze Matter”). The Company, its Chief Executive Officer and its former 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 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, an d by making positive statements about the Company’s business, operations and prospects that were allegedly materially misleading and/or lacked a reasonable basis. On July 21, 2020, the court appointed Rajeev Yalamanchili as Lead Plaintiff. Lead Plaintiff filed an Amended Complaint on September 30, 2020. The litigation is in its initial stages. 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. 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 2020 and 2019. As of December 31, 2020 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, 2020 and 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, 2020 and 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.

Leases [Abstract]
Leases	21. Leases : We adopted ASU 2016-02, “Leases, (Topic 842)” on January 1, 2019, which resulted in the recognition of operating leases on the balance sheet in 2019 and going forward. See Note 1 for more information on the adoption of ASU 2016-02. 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 Twelve Months Ended December 31, 2020 2019 Operating lease cost $ 3,010 $ 2,936 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 2,473 $ 1,889 Right-of-use assets obtained in exchange for new operating lease liabilities $ — $ — We incurred $19 thousand and $26 thousand in short-term lease payments not included in our lease liability during the years ended December 31, 2020 and 2019, respectively.

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, until exited during 2020, satellite launch property/casualty insurance products and services, as well as certain specialty programs. Our Commercial Accounts 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 $55.9 million, and had a fair value of $26.6 million and $41.7 million, as of December 31, 2020 and 2019, 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 $49.1 million and a fair value of $54.3 million and $49.8 million, as of December 31, 2020 and 2019, respectively. 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 with changes in fair value recognized in net income. Equity securities with readily determinable fair values are not required to be evaluated for other-than-temporary impairment. Other investments as of December 31, 2019 consisted of an equity warrant which was 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 2020 and 2019, we deferred ($152.7) million and ($156.8) million of direct policy acquisition costs and amortized $165.6 million and $141.0 million of deferred direct policy acquisition costs, respectively. During 2020 and 2019, we deferred $79.0 million and $160.8 million of ceding commission acquisition costs and amortized ($86.7) million and ($153.7) million of deferred ceding commission acquisition costs, respectively. Therefore, the net amortization (deferrals) of policy acquisition costs were $5.2 million and ($8.7) million for 2020 and 2019, respectively.
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 quantitative impairment test requires an impairment loss 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). We have elected to perform our goodwill impairment test on the first day of the fourth quarter, October 1, of each year. In connection with our normal process for evaluating impairment triggering events, during the first quarter of 2020 we determined that a significant decline in market capitalization below the Company’s stockholders’ equity indicated the impairment of the goodwill and indefinite-lived intangible assets included on the balance sheet. As a result, the Company took a $44.7 million charge to goodwill and a $1.3 million charge to indefinite-lived intangible assets during the first quarter of 2020. Consequently, as of December 31, 2020 there was no goodwill reported on our consolidated balance sheet.
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. (see Note 21)
Property and Equipment	Property and Equipment Property and equipment (including leasehold improvements), aggregating $36.3 million and $34.6 million, at December 31, 2020 and 2019, 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 $2.9million and $3.4 million of leasehold incentives at December 31, 2020 and 2019, respectively, from the adoption of ASU 2016-02, “Leases (Topic 842)” effective January 1, 2019. Depreciation expense for 2020 and 2019 was $3.3 million and $3.0 million, respectively. Accumulated depreciation was $27.1 million and $23.8 million at December 31, 2020 and 2019, respectively. Under ASC 360, “Impairment or disposal of long-lived assets,” property and equipment is tested for impairment annually
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 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, 2020 and 2019. 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 $7.2 million and $8.7 million for the years ended December 31, 2020 and 2019, 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 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. Since the amendments were only disclosure related, our financial statements were not 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 this guidance did not have a material effect on the Company’s results of operations, financials position or liquidity. 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 gave 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, 2020, $14.0 million of right-of-use assets and $15.9 million of lease liabilities for operating leases were included in the other assets other liabilities Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform In December 2019, the FASB issued updated guidance for 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. 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.
