Goodwill Disclosure [Abstract]
Goodwill Disclosure [Text Block]	9. GOODWILL The following table shows the carrying amount of goodwill by segment as of December 31, 2019 and 2018 and the changes in goodwill for the years then ended (in thousands): Tech-focused Other Total Goodwill at January 1, 2018 $ 157,477 $ 13,314 $ 170,791 Foreign currency translation adjustment (3,503 ) — (3,503 ) Sale of business — (13,314 ) (13,314 ) Goodwill at December 31, 2018 $ 153,974 $ — $ 153,974 Foreign currency translation adjustment 2,085 — 2,085 Goodwill at December 31, 2019 $ 156,059 $ — $ 156,059 The annual impairment tests for the Tech-focused reporting unit, which were performed as of October 1, 2019 and 2018, resulted in the fair value of the reporting unit exceeding the carrying value by 37% and 40%, respectively. Results for the Tech-focused reporting unit for the fourth quarter of 2019 and estimated future results as of December 31, 2019 are consistent with or have exceeded the October 1, 2019 analysis. As a result, the Company believes it is not more likely than not that the fair value of the reporting unit is less than the carrying value as of December 31, 2019. Therefore, no interim impairment testing was performed as of December 31, 2019. The amount of goodwill as of December 31, 2019 allocated to the Tech-focused reporting unit was $156.1 million. Determining the fair value of a reporting unit is judgmental in nature and requires the use of estimates and key assumptions, particularly assumed discount rates and projections of future operating results. The discount rate applied for the Tech-focused reporting unit was 13.2%. An increase to the discount rate applied or reductions to future projected operating results could result in future impairment of the Tech-focused reporting unit’s goodwill. It is reasonably possible that changes in judgments, assumptions and estimates the Company made in assessing the fair value of goodwill could cause the Company to consider some portion or all of the goodwill of the Tech-focused reporting unit to become impaired. In addition, a future decline in the overall market conditions and/or changes in the Company’s market share could negatively impact the estimated future cash flows and discount rates used to determine the fair value of the reporting unit and could result in an impairment charge in the foreseeable future.

SIGNIFCANT ACCOUNTING POLICIES

SIGNIFCANT ACCOUNTING POLICIES (Notes)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation — The consolidated financial statements include the accounts of DHI and its wholly-owned subsidiaries and cost method investment. All intercompany balances and transactions have been eliminated in consolidation. Revenue Recognition — On January 1, 2018, we adopted Topic 606 applying the modified retrospective method to all contracts that were not completed as of January 1, 2018. Results for periods beginning after January 1, 2018 are presented under Topic 606, while prior periods are reported under the accounting standards in effect for the period presented. Under Topic 606, we recognize revenue when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to receive in exchange for those goods or services. Revenue is recognized net of customer discounts ratably over the service period. Billings with customers are based on contractual schedules. Customer billings delivered in advance and payments received in advance of services being rendered are recorded as deferred revenue and recognized over the service period. We generate revenues from the following sources: Recruitment packages. Recruitment package revenues are derived from the sale to recruiters and employers of a combination of job postings and access to a searchable database of candidates on Dice, ClearanceJobs, eFinancialCareers and Rigzone (sold the RigLogix portion of the Rigzone business on February 20, 2018 and DHI transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018). Certain of the Company’s arrangements include multiple performance obligations, which primarily consists of the ability to post jobs and access to a searchable database of candidates. The Company determines the units of accounting for multiple performance obligations in accordance with Topic 606. Specifically, the Company considers a performance obligation as a separate unit of accounting if it has value to the customer on a standalone basis. The Company’s arrangements do not include a general right of return. Services to customers buying a package of available job postings and access to the database are delivered over the same period and revenue is recognized ratably over the length of the underlying contract, typically from one to twelve months. The separation of the package into two deliverables results in no change in revenue recognition since delivery of the two services occurs over the same time period. Advertising revenue. Advertising revenue is recognized over the period in which the advertisements are displayed on the websites or at the time a promotional e-mail is sent out to the audience. Classified revenue. Classified job posting revenues are derived from the sale of job postings to recruiters and employers. A job posting is the ability to list a job on the website for a specified time period. Revenue from the sale of classified job postings is recognized ratably over the length of the contract or the period of actual usage. Data services revenue. Access to the Company’s database of energy industry data is provided to customers for a fee. Data services revenue is recognized ratably over the length of the underlying contract, typically from one to twelve months. The data services business, called RigLogix, was sold on February 20, 2018. Career fair and recruitment event booth rentals. Career fair and recruitment event revenues are derived from renting booth space to recruiters and employers. Revenue from these sales are recognized when the career fair or recruitment event is held. Concentration of Credit Risk— Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand. The Company believes it is not exposed to any significant credit risk. The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not require collateral on accounts receivable. No single customer represents 10% or more of revenues for the years ended December 31, 2019, 2018 and 2017. Allowance for Doubtful Accounts— The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of DHI’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Statements of Cash Flows— All bank deposits are considered cash and cash equivalents. The supplemental disclosures to the accompanying consolidated statements of cash flows are as follows (in thousands): 2019 2018 2017 Supplemental cash flow information: Interest paid $ 639 $ 1,807 $ 3,254 Taxes paid 1,506 2,634 4,697 Non-cash investing and financing activities: Capital expenditures on fixed assets included in accounts payable and accrued expenses 140 223 63 Investments— During 2017, pursuant to the achievement of certain performance milestones, the Company purchased additional preferred stock representing a 2.3% interest in the fully diluted shares of a leading tech skills assessment company for $0.5 million , bringing its total interest to 10.0% . During the year ended December 31, 2018, the skills assessment company completed an additional equity offering, lowering DHI's total interest to 7.6% . As of December 31, 2019, it was not practicable to estimate the fair value of the preferred stock as the shares are not traded. The Company has elected the measurement alternative in accordance with FASB ASC 321, Investments - Equity Securities , and is carrying the investment at its original cost of $2.0 million . The investment is included in other assets on the consolidated balance sheets. On January 31, 2018, the Company transferred a majority ownership of the BioSpace business to BioSpace management with zero proceeds received from the transfer. The Company retained a 20% preferred share interest in the BioSpace business. The fair value of the investment was estimated to be zero at the time of the transfer. As of December 31, 2019, it was not practicable to estimate the fair value of the preferred stock investment as the shares are not traded. The investment is recorded at cost, which is zero. Upon a liquidation, sale or change in control of BioSpace within five years of January 31, 2018, the Company has the right to the first $1.0 million of proceeds or the option to convert its 20% preferred stock interest to a 20% common stock interest. On January 31, 2023, the 20% preferred share interest will convert to a 20% common share interest. Rigzone is a website dedicated to delivering online content, data , and career services in the oil and gas industry in North America, Europe, the Middle East, and Asia Pacific. Oil and gas companies, as well as companies that serve the energy industry, use Rigzone to find talent for roles such as petroleum engineers, sales, professionals with energy industry expertise and skilled tradesmen. On August 31, 2018, the Company transferred a majority ownership of the Rigzone business to Rigzone management, while retaining a 40% common share interest, with zero proceeds received from the transfer. The Company agreed to provide $0.4 million of funding to the Rigzone business, which was recorded in accounts payable and accrued expenses on the consolidated balance sheets as of December 31, 2018. The Company has no further funding requirements to the Rigzone business. The Company has evaluated the 40% common share investment in the Rigzone business and has determined the investment meets the definition and criteria of a variable interest entity ("VIE"). The Company evaluated the VIE and determined that the Company does not have a controlling financial interest in the VIE, as the Company does not have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance. The common share interest is being accounted for under the equity method of accounting as the Company has the ability to exercise significant influence over Rigzone. As accumulated earnings of the VIE have been approximately zero since the date of transfer, the investment continues to be recorded at cost, which was zero at December 31, 2019. Fixed Assets— Depreciation of equipment, furniture and fixtures, computer software and capitalized website development costs are provided under the straight-line method over estimated useful lives ranging from two to five years. Amortization of leasehold improvements is provided over the shorter of the term of the related lease or the estimated useful life of the improvement. The cost of additions and betterments is capitalized, and repairs and maintenance costs are charged to operations in the periods incurred. Capitalized Software Costs— Capitalized software costs consist of costs to purchase and develop software for internal use. The Company capitalizes certain incurred software development costs in accordance with the Internal Use Software subtopic of the FASB ASC. Costs incurred during the application-development stage for software bought and further customized by outside vendors for the Company’s use and software developed by a vendor for the Company’s proprietary use have been capitalized. Website Development Costs— The Company capitalizes certain costs incurred in designing, developing, testing and implementing enhancements to its websites. These costs are amortized over the enhancement’s estimated useful life, which generally approximates two years. Costs related to the planning and post implementation phases of website development efforts are expensed as incurred. Goodwill and Indefinite-Lived Acquired Intangible Assets— Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. The indefinite-lived acquired intangible assets include the Dice trademarks and brand name. The Company performs a test for impairment of goodwill and indefinite-lived intangible assets annually on October 1, or more frequently if indicators of potential impairment exist, to determine if the carrying value of the recorded asset is impaired. The impairment review process for goodwill compares the fair value of the reporting unit in which goodwill resides to its carrying value. The impairment review process for indefinite-lived intangible assets compares the fair value of the assets to their carrying value. The determination of whether or not the asset has become impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the value of the Company’s reporting units or the intangible asset. Changes in the Company’s strategy and/or market conditions could significantly impact these judgments and require adjustments to recorded amounts of goodwill or indefinite-lived intangible assets. See Note 5 for discussion of impairment charges. Capitalized Contract Costs— The Company capitalizes certain contract acquisition costs consisting primarily of commissions paid when contracts are signed. For costs incurred to obtain new business sales contracts, the Company capitalizes and expenses these costs over an average customer life, which was approximately two years as of December 31, 2019. For the remaining sales contracts, the Company capitalizes and expenses these costs over a weighted average contract term, which was approximately one year as of December 31, 2019. See Note 3 for additional contract acquisition cost disclosures. Foreign Currency Translation— For the Company’s foreign operations whose functional currency is not the U.S. dollar, the assets and liabilities are translated into U.S. dollars at current exchange rates. Resulting translation adjustments are reflected as Other Comprehensive Income (Loss). Revenue and expenses are translated at average exchange rates for the period. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are charged to operations as incurred. Advertising Costs— The Company expenses advertising costs as they are incurred. Advertising expense for the years ended December 31, 2019, 2018 and 2017 was $20.1 million , $26.7 million and $35.3 million , respectively. Income Taxes— The Company recognizes deferred taxes by the asset and liability method. Under this method, deferred income taxes are recognized for differences between the financial statement and tax bases of assets and liabilities at enacted statutory tax rates in effect for the years in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The primary sources of temporary differences are stock-based compensation, amortization and impairment of intangible assets, and depreciation of fixed assets. Stock-Based Compensation— The Company has a plan to grant equity awards to certain employees and directors of the Company and its subsidiaries. See Note 15. Fair Value of Financial Instruments— The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses approximate their fair values. The Company’s long-term debt consists of borrowings under its credit facility. See Note 5 for fair value disclosures. Risks and Uncertainties— The Company is subject to the risks, expenses and uncertainties frequently encountered by companies in the rapidly evolving markets for online products and services. These risks include the failure to develop and extend the Company’s online service brands, the rejection of the Company’s services by consumers, vendors and/or advertisers, the inability of the Company to maintain and increase the levels of traffic on its online services, as well as other risks and uncertainties. In the event that the Company does not successfully execute its business plan, certain assets may not be recoverable. Use of Estimates— The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. DHI’s significant estimates include the useful lives and valuation of fixed assets and intangible assets, goodwill, the income tax valuation allowance, and the assumptions used to value the Performance-Based Restricted Stock Units (“PSUs”) of the Company. Earnings per Share— The Company follows the Earnings Per Share topic of the FASB ASC in computing earnings per share (“EPS”). Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding. When the effects are dilutive, diluted earnings per share is calculated using the weighted average number of shares outstanding, and the dilutive effect of stock-based compensation awards as determined under the treasury stock method. Certain stock awards were excluded from the computation of diluted (loss) earnings per share due to their anti-dilutive effect. See Note 19. New Accounting Pronouncements— In May 2014, FASB issued ASU No. 2014-09 ("Topic 606"), Revenue from Contracts with Customers. Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition, and requires entities to measure and recognize revenue and the related cash flows it expects to be entitled for the transfer of promised goods or services to customers and requires an entity to recognize the incremental costs of obtaining a contract with a customer as an asset if the entity expects to recover those costs over time. Topic 606 became effective for reporting periods beginning after December 15, 2017. Topic 606 provides companies with two implementation methods. Companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). The Company has chosen the modified retrospective application method and has implement Topic 606 effective January 1, 2018. The Company has determined that the January 1, 2018 cumulative effect to its revenue streams was an increase of approximately $0.2 million to deferred revenues, and the cumulative effect to its contract acquisition costs was an increase to contract acquisition cost assets of approximately $6.1 million , with a net after tax increase to retained earnings of approximately $4.5 million . The cumulative impact on contract acquisition costs was computed based on contracts in force as of December 31, 2017 using average commission rates on both new business sales to be amortized over approximately two years and the remaining sales contracts to be amortized over approximately one year. See Note 3 to the Notes to the Consolidated Financial Statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new standard aims to improve existing U.S. GAAP and will change certain aspects of accounting for equity investments, financial instruments, financial liabilities, and presentation and related disclosures. The updated standard became effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the new standard in the first quarter of 2018, and has determined the adoption did not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases . The new standard has requirements on how to account for leases by both the lessee and the lessor and adds clarification for what constitutes a lease, among other items. The updated standard becomes effective for fiscal years beginning after December 15, 2018 and interim periods the following year, with early adoption permitted. The new standard must be applied using a modified retrospective transition. In July 2018, the FASB issued updated guidance which allows an additional transition method to adopt the new standard at the adoption date, as compared to the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. DHI has implemented the new standard effective January 1, 2019 and has elected to recognize a cumulative effect adjustment to the beginning balance of retained earnings in the period of adoption. Adoption of this standard has resulted in a right-of-use asset of $17.2 million, net of accrued rent and lease exit costs, and related operating lease liability of $18.0 million being established on the Company's balance sheet on January 1, 2019, with no cumulative-effect adjustment to retained earnings. Right-of-Use ("ROU") assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments arising from the lease. The Company has implemented processes and tools to assist in the ongoing lease data collection and analysis, and has updated accounting policies and internal controls as a result of adopting this standard. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting . The Company adopted the standard during the three months ended March 31, 2017. The new standard requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled, rather than in additional paid-in capital. Accordingly, the new standard eliminates the requirement to reclassify excess tax benefits from operating activities to financing activities in the statement of cash flows. Additionally, the Company can now make a policy election to account for forfeitures as they occur. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement were applied prospectively. The tax effect of awards vested resulted in income tax expense of $1.4 million during the twelve months ended December 31, 2017. The Company will record forfeitures as they occur, rather than estimating in advance. On January 1, 2017, under the modified retrospective transition method as required by the standard, the Company recorded a cumulative-effect adjustment of $0.3 million to decrease accumulated earnings and increase additional paid-in capital to remove estimated forfeitures on all outstanding equity awards after December 31, 2016. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 changes how entities will account for credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current "incurred loss" model with an "expected loss" model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of a financial asset. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2022 for Smaller Reporting Companies. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other . The new standard eliminates Step 2 from the goodwill impairment test and requires the Company to compare the fair value of a reporting unit with its carrying amount. The Company should recognize an impairment charge for the amount by which the carrying amount exceeds the fair value. The standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Accordingly, the Company has adopted the new standard during the year ended December 31, 2017, which did not have a material impact on the consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement . This standard removes, modifies, and adds certain disclosure requirements for fair value measurements. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The new standard requires entities that are customers in cloud computing arrangements to defer implementation costs if they would be capitalized by the entity in software licensing arrangements under the internal-use software guidance. ASU No. 2018-15 is effective for fiscal years beginning after December 15, 2019 and interim periods within those years and early adoption is permitted. The amendments allow either a retrospective or prospective approach to all implementation costs incurred after adoption. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12 Simplifying the Accounting for Income Taxes . The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company is evaluating the expected impact of this standard on its consolidated financial statements.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended
	Dec. 31, 2019
Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The FASB ASC topic on Fair Value Measurements and Disclosures defines fair value, establishes a framework for measuring fair value and requires certain disclosures for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. As a basis for considering assumptions, a three-tier fair value hierarchy is used, which prioritizes the inputs used in measuring fair value as follows: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets. • Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, other assets, accounts payable and accrued expenses and long-term debt approximate their fair values. The fair value of the long-term debt was estimated using present value techniques and market based interest rates and credit spreads. The estimated fair value of long-term debt is based on Level 2 inputs. Certain assets and liabilities are measured at fair value on a non-recurring basis. These assets include goodwill and intangible assets which result as acquisitions occur. Items valued using such internally generated valuation techniques are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable. Such instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, for example, when there is evidence of impairment. Impairment —The impairment review process for goodwill compares the fair value of the reporting unit in which the goodwill resides to the carrying value of that reporting unit. If the fair value of the reporting unit is less than the carrying value, an impairment charge is recorded for the excess of the carrying value over the fair value of the reporting unit. Fair values are determined either by using a discounted cash flow methodology or by using a combination of a discounted cash flow methodology and a market comparable method. The discounted cash flow methodology is based on projections of the amounts and timing of future revenues and cash flows, assumed discount rates and other assumptions as deemed appropriate. Factors such as historical performance, anticipated market conditions, operating expense trends and capital expenditure requirements are considered. Additionally, the discounted cash flows analysis takes into consideration cash expenditures for product development, other technological updates and advancements to the websites and investments to improve the candidate databases. The market comparable method indicates the fair value of a business by comparing it to publicly traded companies in similar lines of business or to comparable transactions or assets. Considerations for factors such as size, growth, profitability, risk and return on investment are analyzed and compared to the comparable businesses and adjustments are made. A market value of invested capital of the publicly traded companies is calculated and then applied to the entity’s operating results to arrive at an estimate of value. As required under FASB ASC 360, Impairment or Disposal of Long-Lived Assets , an impairment loss shall be recognized only if the carrying amount of the long-lived asset is not recoverable and exceeds its fair value. During 2017, the Company performed an in-depth review of the getTalent product and the market outlook due to slow sales of the product and the high cost of development. Based on the review, the Company determined the required investments to competitively position the product were too high. As a result, the product offering was canceled. The long-lived assets of getTalent were tested for recoverability. This process resulted in an impairment of capitalized website development costs of $9.3 million , which was recorded in the third quarter of 2017 and reduced the net book value of assets related to getTalent to zero. GetTalent (discontinued in the third quarter of 2017) is included in Other as defined in Note 18.

Intangible Assets, Net (Excluding Goodwill) [Abstract]
Acquired Intangible Assets, Net	ACQUIRED INTANGIBLE ASSETS, NET As a result of the sale of Hcareers (sold May 22, 2018), the Company disposed of all its remaining unamortized acquired intangible assets. Acquired intangible assets disposed of in conjunction with the sale had costs of $12.9 million and accumulated amortization of $6.7 million . Therefore, as of December 31, 2019 and 2018, the net value of all finite-lived acquired intangible assets was zero. As of December 31, 2019 and 2018, the Company had an indefinite-lived acquired intangible asset of $39.0 million related to the Dice trademark and brand name. The Company evaluates the indefinite-lived acquired intangible asset for impairment on an annual basis. No impairment has been recorded during the twelve months ending December 31, 2019 and 2018. Considering the recognition of the Dice brand, its long history, awareness in the talent acquisition and staffing services market, and the intended use, the remaining useful life of the Dice.com trademarks and brand name was determined to be indefinite. We determine whether the carrying value of recorded indefinite-lived acquired intangible assets is impaired on an annual basis or more frequently if indicators of potential impairment exist. The impairment review process compares the fair value of the indefinite-lived acquired intangible assets to its carrying value. If the carrying value exceeds the fair value, an impairment loss is recorded. The impairment test performed as of October 1, 2019 and 2018 resulted in the fair value of the Dice trademarks and brand name exceeding the carrying value by 26% and 2%, respectively. The increase in the fair value over the carrying value is driven by the industry growth expectations described below and the Company's investments in its product and its sales team, combined with a lower discount rate as a result of a decline in the risk-free rate. Revenue attributable to the Dice trademarks and brand name have declined during the year ended December 31, 2019 due to competition in the technology recruiting market, challenges in developing and introducing new products and product enhancements to the market and the Company’s ability to attribute value delivered to customers. Revenues related to the Dice trademarks and brand name declined 2% and 7% for the years ended December 31, 2019 and 2018, respectively, and declined 3% and 4% for the three months ended December 31, 2019 and 2018, respectively, representing a decrease in the rate of decline for each period. Revenue projections for the year ending December 31, 2020 include a modest increase compared to the year ended December 31, 2019 and then increasing to rates approaching industry growth projections. The Company’s ability to achieve these revenue projections may be impacted by, among other things, the factors noted above that have contributed to the decline in recent periods. Cash flows attributable to the Dice trademarks and brand name declined during 2019 as a result of the lower revenue, as well as increased spending focused on new and enhanced products. Operating expenses, excluding amortization expense and disposition related and other costs, are projected to increase for the year ending December 31, 2020 as compared to the year ended December 31, 2019, including a small operating margin reduction, as the company continues to invest in new and enhanced products, and then increase at levels that allow for modest operating margin improvements. If future cash flows attributable to the Dice trademark are not achieved, the Company could realize an impairment in a future period. The Company utilized a relief from royalty rate method to value the Dice trademarks and brand name using a royalty rate of 6.0% based on comparable industry studies and improving operating margins and a discount rate of 14.2%. The determination of whether or not indefinite-lived acquired intangible assets have become impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the value of the indefinite-lived acquired intangible assets. Fair values are determined using a profit allocation methodology which estimates the value of the trademark and brand name by capitalizing the profits saved because the company owns the asset. We consider factors such as historical performance, anticipated market conditions, operating expense trends and capital expenditure requirements. Changes in our strategy and/or market conditions could significantly impact these judgments and require adjustments to recorded amounts of intangible assets. If projections are not achieved, the Company could realize an impairment in a future period.

Debt Disclosure [Abstract]
Indebtedness	INDEBTEDNESS Credit Agreement —In November 2018, the Company, together with Dice Inc. (a wholly-owned subsidiary of the Company) and its wholly-owned subsidiary, Dice Career Solutions, Inc. (collectively, the “Borrowers”), entered into a Second Amended and Restated Credit Agreement (the “Credit Agreement”), which matures in November 2023, and replaces the previously existing credit agreement dated November 2015. The Credit Agreement provides for a revolving loan facility of $90 million , with an expansion option up to $140 million , as permitted in the Credit Agreement. The Company borrowed $18 million to repay, in full, all outstanding indebtedness, including accrued interest, under the previous credit agreement and to pay certain costs associated with the Credit Agreement. Unamortized debt issuance costs of $0.2 million were recorded to interest expense at the time of reduction. Borrowings under the Credit Agreement bear interest, at the Company’s option, at a LIBOR rate or a base rate plus a margin. The margin ranges from 1.75% to 2.50% on LIBOR loans and 0.75% to 1.50% on base rate loans, determined by the Company’s most recent consolidated leverage ratio. The facility may be prepaid at any time without penalty. The Credit Agreement contains various customary affirmative and negative covenants and also contains certain financial covenants, including a consolidated leverage ratio and a consolidated interest coverage ratio. Borrowings are allowed under the Credit Agreement to the extent the consolidated leverage ratio, calculated on a pro forma basis, is equal to or less than 2.50 to 1.00 . Negative covenants include restrictions on incurring certain liens; making certain payments, such as stock repurchases and dividend payments; making certain investments; making certain acquisitions; making certain dispositions; and incurring additional indebtedness. Restricted payments are allowed under the Credit Agreement to the extent the consolidated leverage ratio, calculated on a pro forma basis, is equal to or less than 2.00 to 1.00 , plus an additional $5.0 million of restricted payments. The Credit Agreement also provides that the payment of obligations may be accelerated upon the occurrence of customary events of default, including, but not limited to, non-payment, change of control, or insolvency. As of December 31, 2019 , the Company was in compliance with all of the financial covenants under the Credit Agreement. The obligations under the Credit Agreement are guaranteed by two of the Company’s wholly-owned subsidiaries, and secured by substantially all of the assets of the Borrowers and the guarantors and stock pledges from certain of the Company’s foreign subsidiaries. The amounts borrowed as of December 31, 2019 and 2018 are as follows (dollars in thousands): December 31, December 31, Amounts borrowed: Revolving credit facility $ 10,000 $ 18,000 Less: deferred financing costs, net of accumulated amortization of $172 and $25 (565 ) (712 ) Total borrowed $ 9,435 $ 17,288 Available to be borrowed under revolving facility $ 80,000 $ 72,000 Interest rates: LIBOR rate loans: Interest margin 1.75 % 1.75 % Actual interest rates 3.56 % 4.25 % There are no scheduled payments until maturity of the Credit Agreement in November 2023.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Litigation The Company is subject to various claims from taxing authorities, lawsuits and other complaints arising in the ordinary course of business. The Company records provisions for losses when claims become probable and the amounts are reasonably estimable. Although the outcome of these legal matters cannot be determined, it is the opinion of management that the final resolution of these matters will not have a material adverse effect on the Company’s financial condition, operations or liquidity. During the first quarter of 2018, the Company recorded a $1.0 million liability related to a class action lawsuit regarding the applicability of provisions of the Fair Credit Reporting Act (the "FCRA") to one of our products. The lawsuit was brought by Ian Douglas, individually, as a representative of the class and on behalf of the general public, against DHI Group, Inc. and Dice Inc. asserting six claims under the FCRA that the Company's Open Web profiles are "consumer reports" and Dice is a "consumer reporting agency" under the FCRA, including claims pursuant to the private right of action in 15 U.S.C. Section 1681n for alleged willful violations of the FCRA. The action was originally filed in a federal district court on July 26, 2017, but as part of the settlement process, the action was re-filed in the Superior Court of Santa Clara County, California (Case No. 18CV331732). The recorded liability reflected a settlement, which became final and was paid in the third quarter of 2019, that resolved all remaining claims subject to the lawsuit. A compliance hearing is currently scheduled for April 3, 2020. Tax Contingencies The Company operates in a number of tax jurisdictions and is routinely subject to examinations by various tax authorities with respect to income taxes and indirect taxes. The determination of the Company’s worldwide provision for taxes requires judgment and estimation. The Company has reserved for potential examination adjustments to our provision for income taxes and accrual of indirect taxes in amounts which the Company believes are reasonable.

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	STOCK BASED COMPENSATION Under the 2012 Omnibus Equity Award Plan, the Company has granted stock options, restricted stock and Performance-Based Restricted Stock Units (“PSUs”) to certain employees and directors. On January 1, 2017, as a result of ASU No. 2016-09 as discussed in Note 2, the Company began recording expense based upon the number of awards outstanding with no estimate for forfeitures. Previously, the Company estimated forfeitures that it expected would occur and recorded expense based upon the number of awards expected to vest. The Company recorded stock based compensation expense of $ 5.7 million and $ 6.6 million in the years ended December 31, 2019 and 2018, respectively. At December 31, 2019 , there was $9.1 million of unrecognized compensation expense related to unvested awards, which is expected to be recognized over a weighted-average period of approximately 1.5 years. In connection with the employment agreement for the Company's new Chief Executive Officer, the Company granted, as Inducement Grants Under NYSE Rule 303A.08, 1,750,000 restricted stock units during the second quarter of 2018 and 750,000 performance based restricted stock units during the fourth quarter of 2018 to the Company's new Chief Executive Officer. Restricted Stock— Restricted stock is granted to employees of the Company and its subsidiaries, and to non-employee members of the Company’s Board. These shares are part of the compensation plan for services provided by the employees or Board members. The closing price of the Company’s stock on the date of grant is used to determine the fair value of the grants. The expense related to the restricted stock grants is recorded over the vesting period as described below. There was no cash flow impact resulting from the grants. The restricted stock vests in various increments either quarterly or on the anniversaries of each grant, subject to the recipient’s continued employment or service through each applicable vesting date. Vesting occurs over one year for Board members and over two to four years for employees. A summary of the status of restricted stock awards as of December 31, 2019 , 2018 , and 2017 and the changes during the periods then ended is presented below: Year Ended December 31, 2019 2018 2017 Shares Weighted- Average Fair Value at Grant Date Shares Weighted- Average Fair Value at Grant Date Shares Weighted- Average Fair Value at Grant Date Non-vested at beginning of the period 4,518,932 $ 2.32 2,393,257 $ 5.48 2,226,375 $ 7.87 Granted 2,257,940 $ 2.72 4,087,342 $ 1.68 1,724,500 $ 4.05 Forfeited (560,375 ) $ 2.75 (439,750 ) $ 4.20 (655,000 ) $ 6.54 Vested (2,221,710 ) $ 2.36 (1,521,917 ) $ 5.03 (902,618 ) $ 7.89 Non-vested at end of period 3,994,787 $ 2.46 4,518,932 $ 2.32 2,393,257 $ 5.48 PSUs— PSUs are granted to employees of the Company and its subsidiaries. These shares are granted under two compensation agreements that are for services provided by the employees. Under the first agreement, with a grant during the year ended December 31, 2017, the fair value of PSUs were measured using the Monte Carlo pricing model. The expense related to these PSUs are recorded over the vesting period. These shares will vest on the dates the Compensation Committee certifies the Company’s achievement of stock price performance relative to the Russell 2000 Index, provided that the recipient remains employed through such date. Performance will be measured over three separate measurement periods: a one-year measurement period, a two-year measurement period and a three-year measurement period. For performance periods one and two, vesting is not to exceed the total grant divided by three. For performance period three, vesting is no less than zero and no greater than 150% of the initial grant less shares vested in performance periods one and two. As of December 31, 2019, there were 237,500 unvested shares related to this agreement. Under the second agreement, the fair value of the PSUs are measured at the grant date fair value of the award, which was determined based on an analysis of the probable performance outcomes. The performance period is based on the achievement of bookings targets during the year ended December 31, 2019, as defined in the agreement. The earned shares will then vest over a three year period, one-third on each of the first, second, and third anniversaries of the grant date, or if later, the date the Compensation Committee certifies the performance results with respect to the performance period. As of December 31, 2019, there were 1,427,150 unvested shares related to the second agreement. There were no cash flow impact resulting from the grants. The fair value of PSUs measured using the Monte Carlo pricing model utilized the following assumptions: Year Ended December 31, 2017 Weighted average fair value of PSUs granted $ 5.38 Dividend yield of DHI Group, Inc. stock — % Dividend yield of Russell 2000 Index 1.4 % Risk free interest rate 1.5 % Volatility of DHI Group, Inc. stock 41.0 % Volatility of Russell 2000 Index 16.7 % A summary of the status of PSUs as of December 31, 2019 , 2018, and 2017 and the changes during the periods then ended, is presented below: Year Ended December 31, 2019 2018 2017 Shares Weighted- Average Fair Value at Grant Date Shares Weighted- Average Fair Value at Grant Date Shares Weighted- Average Fair Value at Grant Date Non-vested at beginning of the period 1,255,000 $ 3.45 760,003 $ 6.92 580,004 $ 8.02 Granted 837,150 $ 2.54 750,000 $ 1.58 397,500 $ 5.38 Forfeited (427,500 ) $ 5.26 (255,003 ) $ 8.27 (217,501 ) $ 7.04 Vested — $ — — $ — — $ — Non-vested at end of period 1,664,650 $ 2.53 1,255,000 $ 3.45 760,003 $ 6.92 Stock Options— The fair value of each option grant is estimated using the Black-Scholes option-pricing model using the weighted-average assumptions in the table below. This valuation model requires the Company to make assumptions and judgments about the variables used in the calculation, including the fair value of the Company’s common stock, the expected life (the period of time that the options granted are expected to be outstanding), the volatility of the Company’s common stock, a risk-free interest rate and expected dividends. The expected life of options granted is derived from historical exercise behavior. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury rates in effect at the time of grant. The stock options vest 25% after one year, beginning on the first anniversary date of the grant, and 6.25% each quarter following the first anniversary. There was no cash flow impact resulting from the grants. No stock options were granted during the years ended December 31, 2019 , 2018 , and 2017. A summary of the status of options previously granted as of December 31, 2019 , 2018 , and 2017 , and the changes during the periods then ended is presented below: Year Ended December 31, 2019 Options Weighted-Average Exercise Price Aggregate Intrinsic Value Options outstanding at January 1 327,000 $ 8.35 $ — Exercised — $ — $ — Forfeited (137,000 ) $ 8.46 — Options outstanding at December 31 190,000 $ 8.28 $ — Exercisable at December 31 190,000 $ 8.28 $ — Year Ended December 31, 2018 Options Weighted-Average Exercise Price Aggregate Intrinsic Value Options outstanding at January 1 1,101,875 $ 9.28 $ — Exercised — $ — $ — Forfeited (774,875 ) $ 9.67 — Options outstanding at December 31 327,000 $ 8.35 $ — Exercisable at December 31 327,000 $ 8.35 $ — Year Ended December 31, 2017 Options Weighted-Average Exercise Price Aggregate Intrinsic Value Options outstanding at January 1 1,779,613 $ 8.46 $ 50,869 Exercised (66,188 ) $ 6.08 $ 12,821 Forfeited (611,550 ) $ 7.25 — Options outstanding at December 31 1,101,875 $ 9.28 $ — Exercisable at December 31 1,076,155 $ 9.32 $ — Options expected to vest on December 31 25,720 $ 7.43 The weighted-average remaining contractual term of options exercisable at December 31, 2019 is 0.8 years years.

The capital losses expire in 2023 and 2024. The tax credit carryforward period is indefinite. The Company has recorded valuation allowances of $5.1 million and $5.3 million , respectively, at December 31, 2019 and 2018 in order to measure only the portion of the deferred tax assets which are more likely than not to be realized.

Changes included a reduction in the U.S. statutory federal tax rate from 35% to 21%; the transition of U.S. international taxation from a worldwide tax system to a territorial system; a one-time transition tax on the deemed repatriation of undistributed earnings from foreign subsidiaries; and a tax on global intangible low-taxed income earned by foreign subsidiaries. Subsequent to enactment of the TCJA in December 2017, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to provide guidance regarding accounting for the TCJA’s impact. SAB 118 required companies to recognize those tax items for which accounting had been completed. For items whose accounting had not been completed, companies were required to recognize provisional amounts to the extent they were reasonably estimable, with subsequent adjustments over a measurement period as more information was available and calculations were finalized. The measurement period provided in SAB 118 concluded as of December 2018. As of December 31, 2017, the Company applied the guidance of SAB 118 and recorded a provisional decrease of $3.3 million in its deferred tax liabilities to reflect the new U.S. statutory rate of 21%; and recorded a liability of $3.0 million less tax credits of $1.4 million for a $1.6 million provisional estimate of the transition tax on the deemed repatriation of foreign earnings. In the year ended December 31, 2018, the Company completed its measurement-period analysis of the impact of the TCJA on its deferred tax liabilities and its transition tax liability. No change was made to the provisional adjustment of the deferred tax liabilities. For the transition tax, the Company recognized a measurement-period adjustment on the basis of revised foreign earnings computations and additional guidance issued by U.S. federal and state tax authorities. The adjustment increased the transition tax liability to $2.0 million , resulting in tax expense of $0.4 million . In the year ended December 31, 2019, the Company increased its transition tax liability to reflect further guidance issued by tax authorities, resulting in tax expense of $0.1 million . As of December 31, 2017, the Company indicated that it was evaluating the impact of the TCJA on the Company's existing accounting position with regard to indefinite reinvestment, which was that with the exception of its Canada subsidiary, all unremitted earnings of foreign subsidiaries were indefinitely reinvested outside the U.S. The Company completed this evaluation in the year ended December 31, 2018 and made no change to its indefinite reinvestment position. The Company also sold its Canada subsidiary during 2018. As of December 31, 2019, undistributed earnings of all foreign subsidiaries will continue to be indefinitely reinvested outside the U.S., and taxes that would result from distributions have not been provided as determination of the deferred tax liability is not practicable. The TCJA established new rules designed to tax U.S. companies on global intangible low-taxed income ("GILTI") earned by foreign subsidiaries. Companies could make an accounting policy election either to recognize deferred taxes for temporary basis differences related to GILTI; or to recognize tax expense as current period cost in the period when the tax related to GILTI is incurred. As of December 31, 2017, the Company indicated that it was evaluating its policy election alternatives and the impact of GILTI on tax expense. The Company completed this evaluation in the year ended December 31, 2018 and elected to treat tax expense related to GILTI as a current period cost. The Company recognized tax expense of $0.1 million and $0.2 million , respectively, during the years ended December 31, 2019 and 2018 related to its GILTI liability. An uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a tax return not yet filed, that has not been reflected in measuring income tax expense for financial reporting purposes. At December 31, 2019 and 2018 , the Company has recorded a liability of $1.8 million and $1.7 million , respectively, which consists of unrecognized tax benefits of $1.4 million for 2019 and 2018, and estimated accrued interest and penalties of $0.4 million and $0.3 million , respectively. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. During the years ended December 31, 2019 , 2018 and 2017 , interest expense (income) and penalties recorded in the Consolidated Statements of Operations were $94,000 , $(61,000) and $(41,000) , respectively. Following is a reconciliation of the amounts of unrecognized tax benefits, net of tax and excluding interest and penalties, for the years ended December 31, 2019 , 2018 and 2017 (in thousands): 2019 2018 2017 Unrecognized tax benefits—beginning of period $ 1,422 $ 2,539 $ 2,153 Increases in tax positions related to current year 163 330 278 Increases in tax positions related to prior year 41 — 646 Decreases in tax positions related to prior year — (9 ) — Settlements with taxing authorities — (838 ) — Lapse of statute of limitations (192 ) (600 ) (538 ) Unrecognized tax benefits—end of period $ 1,434 $ 1,422 $ 2,539 The foregoing table indicates unrecognized tax benefits, net of tax and excluding interest and penalties. The balance of gross unrecognized benefits was $1.5 million , $1.5 million , and $2.7 million at December 31, 2019, 2018 and 2017, respectively. If the unrecognized tax benefits at December 31, 2019, 2018 and 2017 were recognized in full, tax benefits of $1.8 million , $1.7 million and $2.9 million , respectively, would affect the effective tax rate. The Company files income tax returns in the U.S. and various foreign jurisdictions. The Company is generally no longer subject to examinations by U.S. federal tax authorities for tax years prior to 2016, or by U.S. state and foreign authorities for tax years prior to 2015. The Company believes it is reasonably possible that as much as $0.4 million of its unrecognized tax benefits may be recognized by the end of 2020 as a result of a lapse of the statute of limitations.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The Company previously had two reportable segments which was reduced to one reportable Tech-focused segment when Health eCareers (Healthcare reportable segment) was sold on December 4, 2017. The Company modified its Tech-focused reportable segment in the first quarter of 2019 to reflect the current Tech-focused operating structure. The change comes as a result of the non-tech businesses being divested during 2018, and, as a result, corporate related costs are now reflected as part of the Tech-focused segment. Accordingly, all prior periods have been recast to reflect the current segment presentation. The Company has one reportable segment, Tech-focused, which includes the Dice, Dice Europe (ceased operations on August 31, 2018), ClearanceJobs, eFinancialCareers services, Brightmatter (absorbed into Tech-focused in the third quarter of 2017 and formerly in Other), and corporate related costs (formerly included in Other). Management has organized its reportable segment based upon its internal management reporting. Prior to 2019, the Company had other services and activities that individually were not significant in relation to consolidated revenues, operating income or total assets. These include Hcareers (sold May 22, 2018), Rigzone (sold the RigLogix portion of the Rigzone business on February 20, 2018 and transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018) , Biospace (majority ownership transferred to BioSpace management on January 31, 2018) , and getTalent (discontinued operations in the third quarter of 2017) services, which are recorded in the "Other" category. The Company’s foreign operations are comprised of the Dice Europe (ceased operations on August 31, 2018) operations and a portion of the eFinancialCareers and Rigzone services (sold the RigLogix portion of the Rigzone business on February 20, 2018 and transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018), which operate in Europe, the financial centers of the gulf region of the Middle East, and Asia Pacific. The Company’s foreign operations also included Hcareers (sold May 22, 2018), which operated in Canada. During the 2019 period, the Company changed its method of presenting revenue by geographic region and as such, 2019 is based on the location of each of the Company’s subsidiaries. The prior presentation was based on the customer's location. The Company believes this method better reflects the revenue generated from each geographic region. The prior periods have been recast to be consistent with the 2019 presentation. The following table shows the segment information (in thousands and recast for the change in reportable segments): 2019 2018 2017 By Segment: Revenues: Tech-focused $ 149,370 $ 152,258 $ 158,398 Healthcare — — 24,354 Other — 9,312 25,198 Total revenues $ 149,370 $ 161,570 $ 207,950 Depreciation: Tech-focused $ 9,743 $ 9,001 $ 6,972 Healthcare — — 1,625 Other — 279 1,155 Total depreciation $ 9,743 9,280 $ 9,752 Amortization: Tech-focused $ — $ — $ 132 Healthcare — — 596 Other — 482 1,410 Total amortization $ — $ 482 $ 2,138 Operating income (loss): Tech-focused $ 17,025 $ 7,280 $ 22,867 Healthcare — — (1,507 ) Other — 4,412 1,505 Operating income 17,025 11,692 22,865 Interest expense and other (701 ) (2,054 ) (3,445 ) Other expense — (36 ) (23 ) Income (loss) before income taxes $ 16,324 $ 9,602 $ 19,397 Capital expenditures: Tech-focused $ 14,188 $ 10,060 $ 10,481 Healthcare — — 1,160 Other — 221 1,914 Total capital expenditures $ 14,188 $ 10,281 $ 13,555 2019 2018 2017 By Geography: Revenues: United States $ 119,882 $ 121,097 $ 154,406 United Kingdom 17,343 22,356 25,529 EMEA, APAC and Canada (1) 12,145 18,117 28,015 Non-United States 29,488 40,473 53,544 Total revenues $ 149,370 $ 161,570 $ 207,950 (1) Europe (excluding United Kingdom), the Middle East and Africa (“EMEA”) and Asia-Pacific (“APAC”).

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Policy Text Block]	3. REVENUE RECOGNITION On January 1, 2018, the Company adopted Topic 606 applying the modified retrospective method to all contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 will be presented under Topic 606, while prior period amounts will not be adjusted and continue to be reported under the accounting standards in effect prior to January 1, 2018. We recorded a net increase to opening retained earnings of $4.5 million as of January 1, 2018 due to the cumulative impact of adopting Topic 606. The Company recognizes revenue when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to receive in exchange for those goods or services. Revenue is recognized net of customer discounts ratably over the service period. Customer billings delivered in advance of services being rendered are recorded as deferred revenue and recognized over the service period. The Company generates revenue from recruitment packages, advertising, classifieds, data services, and career fair and recruitment event booth rentals. Disaggregation of revenue Our brands serve various economic professions, such as technology, financial, hospitality (the Hcareers business was sold on May 22, 2018), and energy (sold the RigLogix portion of the Rigzone business on February 20, 2018 and transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018). The following table provides information about disaggregated revenue by brand and includes a reconciliation of the disaggregated revenue with reportable segments (in thousands): For the Year Ended December 31, 2019 For the Year Ended December 31, 2018 Tech-focused Other Total Tech-focused Other Total Dice (1) $ 92,527 — $ 92,527 $ 94,438 $ — $ 94,438 ClearanceJobs 24,745 — 24,745 21,086 — 21,086 eFinancial Careers 32,098 — 32,098 33,758 — 33,758 Dice Europe (2) — — — 2,976 — 2,976 Rigzone (3) — — — — 3,771 3,771 Hcareers (3) — — — — 5,329 5,329 BioSpace (3) — — — — 212 212 Total $ 149,370 $ — $ 149,370 $ 152,258 $ 9,312 $ 161,570 (1) Includes Dice U.S. and Career Events (formerly known as Targeted Job Fairs). (2) The Company ceased Dice Europe operations on August 31, 2018. (3) The Company sold the RigLogix portion of the Rigzone business on February 20, 2018 and transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018. Hcareers was sold on May 22, 2018 and the Company transferred majority ownership of BioSpace to BioSpace management on January 31, 2018. Revenue for periods ending prior to January 1, 2018 have not been presented under Topic 606. Contract Balances The following table provides information about opening and closing balances of receivables and contract liabilities from contracts with customers as required under Topic 606 (in thousands): As of December 31, 2019 As of December 31, 2018 As of January 1, 2018 Receivables $ 21,158 $ 22,850 $ 38,769 Short-term contract liabilities (deferred revenue) 50,568 54,723 83,646 Long-term contract liabilities (deferred revenue) 1,058 1,363 — We receive payments from customers based upon contractual billing schedules; accounts receivable is recorded when customers are invoiced per the contractual billing schedules. As the Company's standard payment terms are less than one year, the Company elected the expedient, where applicable. As a result, the Company did not consider the effects of a significant financing component. Contract liabilities include customer billings delivered in advance of performance under the contract, and associated revenue is realized when services are rendered under the contract. Receivables increase due to customer billings and decrease by cash collected from customers along with business divestitures. Included in January 1, 2018 is $4.4 million of receivables related to businesses divested during the year ended December 31, 2018. Contract liabilities increase due to customer billings and are decreased as performance obligations are satisfied under the contracts. Included in January 1, 2018 is $8.4 million of short-term contract liabilities related to the businesses divested during the year ended December 31, 2018. The Company recognized the following revenues as a result of changes in the contract liability balances in the respective periods (in thousands): Year Ended December 31, 2019 Year Ended December 31, 2018 Revenue recognized in the period from: Amounts included in the contract liability at the beginning of the period $ 54,825 $ 75,967 Transaction price allocated to the remaining performance obligations Under the guidance of Topic 606, the following table includes estimated deferred revenue expected to be recognized in the future related to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period (in thousands): 2020 2021 2022 Total Tech-focused $ 50,568 $ 1,050 $ 8 $ 51,626 Contract acquisition costs In connection with the adoption of Topic 606, we are required to capitalize certain contract acquisition costs consisting primarily of commissions paid when contracts are signed. As allowed for by the practical expedient, the Company is using a portfolio approach for contract acquisition costs, which allows the new revenue guidance to be applied to a portfolio of contracts with similar characteristics. As a result, the Company has applied the portfolio approach to new business contracts and recurring or remaining business contracts. The Company reasonably expects that the effects of applying the portfolio approach would not differ materially from applying Topic 606 at the individual contract level. As of January 1, 2018, the date we adopted Topic 606, we capitalized $6.1 million in contract acquisition costs related to contracts that were not completed. The cumulative effect for contract acquisition costs was computed based on contracts in force as of December 31, 2017 using the average commission rates on both new business sales contracts, to be amortized over approximately two years, and the remaining sales contracts to be amortized over approximately one year. For costs incurred to obtain new business sales contracts, we will record these costs over an average customer life, which was determined using customer renewal rates; for the remaining sales contracts, we will record these costs over the weighted average contract term. The Company recorded $11.8 million and $10.1 million of expense related to the amortization of contract acquisition costs during the years ended December 31, 2019 and 2018, respectively, and there was no impairment loss incurred. During the year ended December 31, 2018, $1.2 million of contract acquisition costs were removed due to the sale of BioSpace and the RigLogix portion of the Rigzone business in the first quarter of 2018, the sale of Hcareers in the second quarter of 2018, and the transfer of majority ownership of the remaining Rigzone business to Rigzone management in the third quarter of 2018.

Leases [Abstract]
Leases	LEASES On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842), applying the modified retrospective transition. Periods beginning after January 1, 2019 will be presented under Topic 842, while prior period amounts will not be adjusted and continue to be reported under the accounting standards in effect prior to January 1, 2019. We have operating leases for corporate office space and certain equipment. Our leases have terms from one year to eight years, some of which include options to renew the lease, and are included in the lease term when it is reasonably certain that the Company will exercise the option. No leases include options to purchase the leased property. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We do not have any lease agreements with related parties. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Based on the present value of the lease payments for the remaining lease term of the Company's existing leases, the Company recorded operating ROU assets of $17.2 million and operating lease liabilities of $18.0 million as of January 1, 2019. Operating lease ROU assets and liabilities commencing after January 1, 2019 are recognized at commencement date based on the present value of lease payments over the lease term. When readily available, the Company uses the implicit rate in determining the present value of the lease payments. When leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on information available at the commencement of the lease, including the lease term. Because the implicit rate in each lease is not available, the Company used its incremental borrowing rate to determine the present value of lease payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet. All operating lease expense is recognized on a straight-line basis over the lease term. The component of lease cost were as follows (in thousands): Year Ended December 31, 2019 Operating lease cost* $ 4,265 Sublease income (1,322 ) Total lease cost $ 2,943 *Includes short-term lease costs and variable lease costs, which are immaterial.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation — The consolidated financial statements include the accounts of DHI and its wholly-owned subsidiaries and cost method investment. All intercompany balances and transactions have been eliminated in consolidation.
Revenue [Policy Text Block]	Revenue Recognition — On January 1, 2018, we adopted Topic 606 applying the modified retrospective method to all contracts that were not completed as of January 1, 2018. Results for periods beginning after January 1, 2018 are presented under Topic 606, while prior periods are reported under the accounting standards in effect for the period presented. Under Topic 606, we recognize revenue when control of the promised goods or services is transferred to our customers at an amount that reflects the consideration to which we expect to receive in exchange for those goods or services. Revenue is recognized net of customer discounts ratably over the service period. Billings with customers are based on contractual schedules. Customer billings delivered in advance and payments received in advance of services being rendered are recorded as deferred revenue and recognized over the service period. We generate revenues from the following sources: Recruitment packages. Recruitment package revenues are derived from the sale to recruiters and employers of a combination of job postings and access to a searchable database of candidates on Dice, ClearanceJobs, eFinancialCareers and Rigzone (sold the RigLogix portion of the Rigzone business on February 20, 2018 and DHI transferred majority ownership of the remaining Rigzone business to Rigzone management on August 31, 2018). Certain of the Company’s arrangements include multiple performance obligations, which primarily consists of the ability to post jobs and access to a searchable database of candidates. The Company determines the units of accounting for multiple performance obligations in accordance with Topic 606. Specifically, the Company considers a performance obligation as a separate unit of accounting if it has value to the customer on a standalone basis. The Company’s arrangements do not include a general right of return. Services to customers buying a package of available job postings and access to the database are delivered over the same period and revenue is recognized ratably over the length of the underlying contract, typically from one to twelve months. The separation of the package into two deliverables results in no change in revenue recognition since delivery of the two services occurs over the same time period. Advertising revenue. Advertising revenue is recognized over the period in which the advertisements are displayed on the websites or at the time a promotional e-mail is sent out to the audience. Classified revenue. Classified job posting revenues are derived from the sale of job postings to recruiters and employers. A job posting is the ability to list a job on the website for a specified time period. Revenue from the sale of classified job postings is recognized ratably over the length of the contract or the period of actual usage. Data services revenue. Access to the Company’s database of energy industry data is provided to customers for a fee. Data services revenue is recognized ratably over the length of the underlying contract, typically from one to twelve months. The data services business, called RigLogix, was sold on February 20, 2018. Career fair and recruitment event booth rentals. Career fair and recruitment event revenues are derived from renting booth space to recruiters and employers. Revenue from these sales are recognized when the career fair or recruitment event is held.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk— Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand. The Company believes it is not exposed to any significant credit risk. The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not require collateral on accounts receivable. No single customer represents 10% or more of revenues for the years ended December 31, 2019, 2018 and 2017.
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Allowance for Doubtful Accounts— The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of DHI’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.
Cash and Cash Equivalents, Policy [Policy Text Block]	Statements of Cash Flows— All bank deposits are considered cash and cash equivalents. The supplemental disclosures to the accompanying consolidated statements of cash flows are as follows (in thousands): 2019 2018 2017 Supplemental cash flow information: Interest paid $ 639 $ 1,807 $ 3,254 Taxes paid 1,506 2,634 4,697 Non-cash investing and financing activities: Capital expenditures on fixed assets included in accounts payable and accrued expenses 140 223 63
Investment, Policy [Policy Text Block]	Investments— During 2017, pursuant to the achievement of certain performance milestones, the Company purchased additional preferred stock representing a 2.3% interest in the fully diluted shares of a leading tech skills assessment company for $0.5 million , bringing its total interest to 10.0% . During the year ended December 31, 2018, the skills assessment company completed an additional equity offering, lowering DHI's total interest to 7.6% . As of December 31, 2019, it was not practicable to estimate the fair value of the preferred stock as the shares are not traded. The Company has elected the measurement alternative in accordance with FASB ASC 321, Investments - Equity Securities , and is carrying the investment at its original cost of $2.0 million . The investment is included in other assets on the consolidated balance sheets. On January 31, 2018, the Company transferred a majority ownership of the BioSpace business to BioSpace management with zero proceeds received from the transfer. The Company retained a 20% preferred share interest in the BioSpace business. The fair value of the investment was estimated to be zero at the time of the transfer. As of December 31, 2019, it was not practicable to estimate the fair value of the preferred stock investment as the shares are not traded. The investment is recorded at cost, which is zero. Upon a liquidation, sale or change in control of BioSpace within five years of January 31, 2018, the Company has the right to the first $1.0 million of proceeds or the option to convert its 20% preferred stock interest to a 20% common stock interest. On January 31, 2023, the 20% preferred share interest will convert to a 20% common share interest. Rigzone is a website dedicated to delivering online content, data , and career services in the oil and gas industry in North America, Europe, the Middle East, and Asia Pacific. Oil and gas companies, as well as companies that serve the energy industry, use Rigzone to find talent for roles such as petroleum engineers, sales, professionals with energy industry expertise and skilled tradesmen. On August 31, 2018, the Company transferred a majority ownership of the Rigzone business to Rigzone management, while retaining a 40% common share interest, with zero proceeds received from the transfer. The Company agreed to provide $0.4 million of funding to the Rigzone business, which was recorded in accounts payable and accrued expenses on the consolidated balance sheets as of December 31, 2018. The Company has no further funding requirements to the Rigzone business. The Company has evaluated the 40% common share investment in the Rigzone business and has determined the investment meets the definition and criteria of a variable interest entity ("VIE"). The Company evaluated the VIE and determined that the Company does not have a controlling financial interest in the VIE, as the Company does not have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance. The common share interest is being accounted for under the equity method of accounting as the Company has the ability to exercise significant influence over Rigzone. As accumulated earnings of the VIE have been approximately zero since the date of transfer, the investment continues to be recorded at cost, which was zero at December 31, 2019.
Property, Plant and Equipment, Impairment [Policy Text Block]	Fixed Assets— Depreciation of equipment, furniture and fixtures, computer software and capitalized website development costs are provided under the straight-line method over estimated useful lives ranging from two to five years. Amortization of leasehold improvements is provided over the shorter of the term of the related lease or the estimated useful life of the improvement. The cost of additions and betterments is capitalized, and repairs and maintenance costs are charged to operations in the periods incurred.
Internal Use Software, Policy [Policy Text Block]	Capitalized Software Costs— Capitalized software costs consist of costs to purchase and develop software for internal use. The Company capitalizes certain incurred software development costs in accordance with the Internal Use Software subtopic of the FASB ASC. Costs incurred during the application-development stage for software bought and further customized by outside vendors for the Company’s use and software developed by a vendor for the Company’s proprietary use have been capitalized.
Property, Plant and Equipment, Preproduction Design and Development Costs [Policy Text Block]	Website Development Costs— The Company capitalizes certain costs incurred in designing, developing, testing and implementing enhancements to its websites. These costs are amortized over the enhancement’s estimated useful life, which generally approximates two years. Costs related to the planning and post implementation phases of website development efforts are expensed as incurred.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Indefinite-Lived Acquired Intangible Assets— Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. The indefinite-lived acquired intangible assets include the Dice trademarks and brand name. The Company performs a test for impairment of goodwill and indefinite-lived intangible assets annually on October 1, or more frequently if indicators of potential impairment exist, to determine if the carrying value of the recorded asset is impaired. The impairment review process for goodwill compares the fair value of the reporting unit in which goodwill resides to its carrying value. The impairment review process for indefinite-lived intangible assets compares the fair value of the assets to their carrying value. The determination of whether or not the asset has become impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the value of the Company’s reporting units or the intangible asset. Changes in the Company’s strategy and/or market conditions could significantly impact these judgments and require adjustments to recorded amounts of goodwill or indefinite-lived intangible assets. See Note 5 for discussion of impairment charges.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation— For the Company’s foreign operations whose functional currency is not the U.S. dollar, the assets and liabilities are translated into U.S. dollars at current exchange rates. Resulting translation adjustments are reflected as Other Comprehensive Income (Loss). Revenue and expenses are translated at average exchange rates for the period. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are charged to operations as incurred.
Advertising Cost [Policy Text Block]	Advertising Costs— The Company expenses advertising costs as they are incurred. Advertising expense for the years ended December 31, 2019, 2018 and 2017 was $20.1 million , $26.7 million and $35.3 million , respectively.
Income Tax, Policy [Policy Text Block]	Income Taxes— The Company recognizes deferred taxes by the asset and liability method. Under this method, deferred income taxes are recognized for differences between the financial statement and tax bases of assets and liabilities at enacted statutory tax rates in effect for the years in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The primary sources of temporary differences are stock-based compensation, amortization and impairment of intangible assets, and depreciation of fixed assets.
Share-based Payment Arrangement [Policy Text Block]	Stock-Based Compensation— The Company has a plan to grant equity awards to certain employees and directors of the Company and its subsidiaries. See Note 15.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value of Financial Instruments— The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses approximate their fair values. The Company’s long-term debt consists of borrowings under its credit facility. See Note 5 for fair value disclosures.
Unusual Risks and Uncertainties [Table Text Block]	Risks and Uncertainties— The Company is subject to the risks, expenses and uncertainties frequently encountered by companies in the rapidly evolving markets for online products and services. These risks include the failure to develop and extend the Company’s online service brands, the rejection of the Company’s services by consumers, vendors and/or advertisers, the inability of the Company to maintain and increase the levels of traffic on its online services, as well as other risks and uncertainties. In the event that the Company does not successfully execute its business plan, certain assets may not be recoverable.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates— The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. DHI’s significant estimates include the useful lives and valuation of fixed assets and intangible assets, goodwill, the income tax valuation allowance, and the assumptions used to value the Performance-Based Restricted Stock Units (“PSUs”) of the Company.
Earnings Per Share, Policy [Policy Text Block]	Earnings per Share— The Company follows the Earnings Per Share topic of the FASB ASC in computing earnings per share (“EPS”). Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding. When the effects are dilutive, diluted earnings per share is calculated using the weighted average number of shares outstanding, and the dilutive effect of stock-based compensation awards as determined under the treasury stock method. Certain stock awards were excluded from the computation of diluted (loss) earnings per share due to their anti-dilutive effect. See Note 19.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements— In May 2014, FASB issued ASU No. 2014-09 ("Topic 606"), Revenue from Contracts with Customers. Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition, and requires entities to measure and recognize revenue and the related cash flows it expects to be entitled for the transfer of promised goods or services to customers and requires an entity to recognize the incremental costs of obtaining a contract with a customer as an asset if the entity expects to recover those costs over time. Topic 606 became effective for reporting periods beginning after December 15, 2017. Topic 606 provides companies with two implementation methods. Companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). The Company has chosen the modified retrospective application method and has implement Topic 606 effective January 1, 2018. The Company has determined that the January 1, 2018 cumulative effect to its revenue streams was an increase of approximately $0.2 million to deferred revenues, and the cumulative effect to its contract acquisition costs was an increase to contract acquisition cost assets of approximately $6.1 million , with a net after tax increase to retained earnings of approximately $4.5 million . The cumulative impact on contract acquisition costs was computed based on contracts in force as of December 31, 2017 using average commission rates on both new business sales to be amortized over approximately two years and the remaining sales contracts to be amortized over approximately one year. See Note 3 to the Notes to the Consolidated Financial Statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new standard aims to improve existing U.S. GAAP and will change certain aspects of accounting for equity investments, financial instruments, financial liabilities, and presentation and related disclosures. The updated standard became effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted the new standard in the first quarter of 2018, and has determined the adoption did not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases . The new standard has requirements on how to account for leases by both the lessee and the lessor and adds clarification for what constitutes a lease, among other items. The updated standard becomes effective for fiscal years beginning after December 15, 2018 and interim periods the following year, with early adoption permitted. The new standard must be applied using a modified retrospective transition. In July 2018, the FASB issued updated guidance which allows an additional transition method to adopt the new standard at the adoption date, as compared to the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. DHI has implemented the new standard effective January 1, 2019 and has elected to recognize a cumulative effect adjustment to the beginning balance of retained earnings in the period of adoption. Adoption of this standard has resulted in a right-of-use asset of $17.2 million, net of accrued rent and lease exit costs, and related operating lease liability of $18.0 million being established on the Company's balance sheet on January 1, 2019, with no cumulative-effect adjustment to retained earnings. Right-of-Use ("ROU") assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the obligation to make payments arising from the lease. The Company has implemented processes and tools to assist in the ongoing lease data collection and analysis, and has updated accounting policies and internal controls as a result of adopting this standard. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting . The Company adopted the standard during the three months ended March 31, 2017. The new standard requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled, rather than in additional paid-in capital. Accordingly, the new standard eliminates the requirement to reclassify excess tax benefits from operating activities to financing activities in the statement of cash flows. Additionally, the Company can now make a policy election to account for forfeitures as they occur. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement were applied prospectively. The tax effect of awards vested resulted in income tax expense of $1.4 million during the twelve months ended December 31, 2017. The Company will record forfeitures as they occur, rather than estimating in advance. On January 1, 2017, under the modified retrospective transition method as required by the standard, the Company recorded a cumulative-effect adjustment of $0.3 million to decrease accumulated earnings and increase additional paid-in capital to remove estimated forfeitures on all outstanding equity awards after December 31, 2016. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 changes how entities will account for credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current "incurred loss" model with an "expected loss" model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of a financial asset. ASU 2016-13 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2022 for Smaller Reporting Companies. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other . The new standard eliminates Step 2 from the goodwill impairment test and requires the Company to compare the fair value of a reporting unit with its carrying amount. The Company should recognize an impairment charge for the amount by which the carrying amount exceeds the fair value. The standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Accordingly, the Company has adopted the new standard during the year ended December 31, 2017, which did not have a material impact on the consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement . This standard removes, modifies, and adds certain disclosure requirements for fair value measurements. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The new standard requires entities that are customers in cloud computing arrangements to defer implementation costs if they would be capitalized by the entity in software licensing arrangements under the internal-use software guidance. ASU No. 2018-15 is effective for fiscal years beginning after December 15, 2019 and interim periods within those years and early adoption is permitted. The amendments allow either a retrospective or prospective approach to all implementation costs incurred after adoption. The Company is evaluating the expected impact of this standard on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12 Simplifying the Accounting for Income Taxes . The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company is evaluating the expected impact of this standard on its consolidated financial statements.
