Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited interim consolidated financial statements of PAR Technology Corporation (the “Company” or “PAR”, "we","us") have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial statements and the instructions to Form 10-Q and Article 8 of Regulation S-X pertaining to interim financial statements. Accordingly, they do not include all information and footnotes required by GAAP for annual financial statements. In the opinion of management, such unaudited interim consolidated financial statements include all normal and recurring adjustments necessary in order to make the unaudited interim consolidated financial statements not misleading and to provide a fair presentation of the results for the interim periods included in this Quarterly Report on Form 10-Q (“Quarterly Report”). Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results of operations that may be expected for any future period. The balance sheet at December 31, 2018 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, please refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 , as filed with the U.S. Securities and Exchange Commission (“SEC”). The preparation of the unaudited interim consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include revenue recognition, stock based compensation, the recognition and measurement of assets acquired and liabilities assumed in business combinations at fair value, the carrying amount of property, plant and equipment including right-to-use assets and liabilities, identifiable intangible assets and goodwill, the measurement of liabilities and equity recognized for outstanding convertible notes, valuation allowances for receivables, inventories and deferred income tax assets, and measurement of contingent consideration at fair value. Actual results could differ from those estimates. The unaudited interim consolidated financial statements and related notes should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , filed with the SEC on March 18, 2019. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date, based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendment is effective for the Company beginning with its fiscal year ending December 31, 2020, however early application is permitted for reporting periods beginning after December 15, 2018. The Company is in the process of evaluating the impact of this standard. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2020, with earlier adoption permitted; it is not expected to have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the fair value measurements disclosures with the primary focus to improve effectiveness of disclosures in the notes to the financial statements that is most important to the users. The new guidance modifies the required disclosures related to the valuation techniques and inputs used, uncertainty in measurement, and changes in measurements applied. ASU 2018-13 will be effective for the Company for its fiscal year beginning after December 15, 2019 and each quarterly period thereafter. Early adoption is permitted. The Company is currently assessing the impact this new guidance may have on the Company’s consolidated financial statements and footnote disclosures. In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other (Topic 350) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 provides guidance on the measurement of costs for internal-use software during the design, development and implementation stages for customers in a cloud based hosting arrangement. AU 2018-15 also requires the capitalized costs associated with the design, development and implementation of cloud based, hosted arrangements to be amortized over the term of the hosting arrangement. ASU 2018-15 will be effective for the Company on January 1, 2020, with earlier adoption permitted; it is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, "Leases (Topic 842)", impacting the accounting for leases intending to increase transparency and comparability of organizations by requiring balance sheet presentation of leased assets and increased financial statement disclosure of leasing arrangements. The revised standard will require entities to recognize a liability for its lease obligations and a corresponding asset representing the right to use the underlying asset over the lease term. Lease obligations are to be measured at the present value of lease payments and accounted for using the effective interest method. The accounting for the leased asset will differ slightly depending on whether the agreement is deemed to be a financing or operating lease. For finance leases, the leased asset is depreciated on a straight-line basis and recorded separately from the interest expense in the income statement resulting in higher expense in the earlier part of the lease term. For operating leases, the depreciation and interest expense components are combined, recognized evenly over the term of the lease, and presented as a reduction to operating income. The ASU requires that assets and liabilities be presented or disclosed separately and classified appropriately as current and noncurrent. The ASU further requires additional disclosure of certain qualitative and quantitative information related to lease agreements. The new standard was effective for the Company beginning January 1, 2019 (see Note 5 - Leases, to the unaudited interim consolidated financial statements).

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Beginning on January 1, 2018, the Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The principle of the revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the company expects to be entitled in exchange for those goods or services. The Company applies the five-step model, as described in ASU 2014-09 Revenue from Contracts with Customers, to contracts when it is probable the Company will collect the consideration it expects in exchange for the goods and services transferred to customers. The following steps are applied to achieve that principle: Step 1: Identify the contract with the customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when the company satisfies a performance obligation The Company's performance obligations are satisfied when services are received by the customer and when the customer takes title to the product and assumes the significant risks and rewards of ownership. Performance Obligations Outstanding The Company's performance obligations outstanding represent the transaction price of firm, non-cancellable orders, with expected delivery dates to customers subsequent to September 30, 2019 and December 31, 2018 , respectively, for work that has not been performed. The aggregate outstanding performance obligations attributable to the Company's two reporting segments, Restaurant/Retail and Government, is as follows: (in thousands) Balance at September 30, 2019 Current - under one year Non-current - over one year Restaurant/Retail $ 10,814 $ 4,148 Government — — TOTAL $ 10,814 $ 4,148 (in thousands) Balance at December 31, 2018 Current - under one year Non-current - over one year Restaurant/Retail $ 9,320 $ 4,407 Government 325 — TOTAL $ 9,645 $ 4,407 Most performance obligations over one year are related to service and support contracts, approximately 72% of which we expect to fulfill within the one-year period and 100% within 60 months. During the three and nine months ended September 30, 2019 , we recognized revenue of $2.1 million and $8.6 million , respectively, that was included in contract liabilities at the beginning of the period. The value of existing Government contracts at September 30, 2019 , net of amounts relating to work performed to that date, was approximately $201.6 million , of which $59.1 million was funded. The value of existing Government contracts at December 31, 2018, net of amounts relating to work performed to that date, was approximately $138.6 million , of which $30.2 million was funded. Funded amounts represent those amounts committed under contract by Government agencies and prime contractors. Disaggregated Revenue The Company disaggregates revenue from contracts from customers by major product group for each of the reporting segments as it believes it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Disaggregation of revenue for the three and nine months ended September 30, 2019 and September 30, 2018 is as follows: (in thousands) Three months ended September 30, 2019 Restaurant/Retail - Point in Time Restaurant/Retail - Over Time Government - Over Time Restaurant/Retail $ 23,599 $ 5,508 $ — Grocery 335 399 — Mission Systems — — 8,420 ISR Solutions — — 7,119 TOTAL $ 23,934 $ 5,907 $ 15,539 (in thousands) Three months ended September 30, 2018 Restaurant/Retail - Point in Time Restaurant/Retail - Over Time Government - Over Time Restaurant/Retail $ 21,761 $ 5,727 $ — Grocery 691 747 — Mission Systems — — 8,283 ISR Solutions — — 9,153 TOTAL $ 22,452 $ 6,474 $ 17,436 (in thousands) Nine months ended September 30, 2019 Restaurant/Retail - Point in Time Restaurant/Retail - Over Time Government - Over Time Restaurant/Retail $ 65,849 $ 18,718 $ — Grocery 1,067 2,029 — Mission Systems — — 25,161 ISR Solutions — — 21,485 TOTAL $ 66,916 $ 20,747 $ 46,646 (in thousands) Nine months ended September 30, 2018 Restaurant/Retail - Point in Time Restaurant/Retail - Over Time Government - Over Time Restaurant/Retail $ 81,422 $ 17,258 $ — Grocery 2,251 2,342 — Mission Systems — — 25,324 ISR Solutions — — 25,997 TOTAL $ 83,673 $ 19,600 $ 51,321 Practical Expedients and Exemptions The Company generally expenses sales commissions when incurred because the amortization period is less than one year or the total amount of commissions is immaterial. We record these expenses in selling, general and administrative. We elected to exclude from the measurement of transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from a customer (for example, sales, use, value added, and some excise taxes).

Acquisition	Acquisition Effective September 30, 2019, ParTech, Inc. ("ParTech"), a wholly-owned subsidiary of the Company, acquired assets of 3M Company's Drive-Thru Communications Systems business ("3M Transaction"), including the XT-1 and G5 headset systems, contracts and intellectual property associated with the business, for a purchase price of $8.4 million (total fair value of assets were $8.4 million , net of warranty liability of $1.4 million , resulting in cash paid of $7.0 million ). The fair values assigned to the acquired assets and assumed liabilities in the table below are based on our best estimates and assumptions as of the reporting date and are considered preliminary pending finalization. The estimates and assumptions are subject to change as we obtain additional information during the measurement period, which may be up to one year from the acquisition date. The assets and liabilities, pending finalization, include the valuation of intangible assets as well as the assumed deferred revenue and deferred income tax balances. (in thousands) Purchase price allocation Developed technology $ 1,200 Customer relationships 3,600 Trademarks 510 Goodwill 2,367 Property, plant and equipment – net 735 Total assets 8,412 Warranty liability 1,412 Cash consideration $ 7,000 The estimated fair values of the developed technology, customer relationships and trademarks were all based on the income approach, which estimates fair value based upon the present value of cash flows that the assets are expected to generate. The method of amortization of identifiable finite-lived intangible assets is based on the expected pattern in which the estimated economic benefits of the respective assets are consumed or otherwise used up. Customer relationships and developed technology assets are amortized on a straight-line basis over their estimated useful lives of five and seven years, respectively. Of the $1,412,000 warranty liability assumed, approximately $712,000 is short-term in nature and is recorded as part of accrued expenses while the remaining $700,000 is recorded as part of other-long term liabilities During the three and nine months ended September 30, 2019, we incurred immaterial acquisition-related expenses, which were recorded in selling, general and administrative expense. The Company has not presented combined pro forma financial information of the Company and the acquired 3M Company’s Drive-Thru Communications Systems business because the results of operations of the acquired business are considered immaterial.

Goodwill and Intangible Assets Disclosure [Abstract]
Identifiable Intangible Assets and Goodwill	Identifiable Intangible Assets and Goodwill Identifiable intangible assets represent intangible assets acquired by the Company in connection with its acquisitions of Brink Software Inc. in 2014 ("Brink Acquisition"), the 3M Transaction, and software development costs. The Company capitalizes certain software development costs for software used in its Restaurant/Retail reporting segment. Software development costs incurred prior to establishing technological feasibility are charged to operations and included in research and development costs. The technological feasibility of a software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary to establish that the software product meets its design specifications, including functionality, features, and technical performance requirements. Software development costs incurred after establishing technological feasibility for software sold as a perpetual license, as defined within ASC 985-20, Software – Costs of Software to be sold, Leased, or Marketed, are capitalized and amortized on a product-by-product basis when the software product is available for general release to customers. Included in "Acquired and internally developed software costs" in the table below is approximately $3.8 million and $3.0 million of costs related to software products that have not satisfied the general release threshold as of September 30, 2019 and December 31, 2018 , respectively. These software products are expected to satisfy the general release threshold within the next 12 months. Software development costs are also capitalized in accordance with ASC 350-40, “Intangibles - Goodwill and Other - Internal - Use Software,” and are amortized over the expected benefit period, which generally ranges from three to five years . Software development costs capitalized during the three and nine months ended September 30, 2019 were $0.7 million and $2.3 million , respectively. Software development costs capitalized during the three and nine months ended September 30, 2018 were $1.0 million and $3.1 million , respectively. Annual amortization, charged to cost of sales is computed using the straight-line method over the remaining estimated economic life of the product, generally three to five years . Amortization of capitalized software development costs from continuing operations for the three and nine months ended September 30, 2019 were $0.5 million and $1.5 million , respectively. Amortization of capitalized software development costs from continuing operations for the three and nine months ended September 30, 2018 were $0.9 million and $2.6 million , respectively. Amortization of intangible assets acquired in the Brink Acquisition amounted to $0.2 million and $0.7 million , respectively, for each of the three and nine month periods ended September 30, 2019 and 2018 . Certain intangible assets were acquired on September 30, 2019 in connection with the 3M acquisition, and as a result no amortization expense was taken on these intangibles for the period ended September 30, 2019 . The components of identifiable intangible assets are (in thousands): September 30, 2019 December 31, 2018 Estimated Useful Life Acquired and internally developed software costs $ 15,103 $ 18,972 3 - 5 years Customer relationships 3,760 160 7 years Non-competition agreements 30 30 1 year 18,893 19,162 Less accumulated amortization (9,755 ) (11,708 ) $ 9,138 $ 7,454 Internally developed software costs not meeting general release threshold 3,847 3,005 Trademarks, trade names (non-amortizable) 910 400 N/A $ 13,895 $ 10,859 The expected future amortization of intangible assets, assuming straight-line amortization of capitalized software development costs and acquisition related intangibles, is as follows (in thousands): 2019, remaining $ 830 2020 2,889 2021 2,068 2022 1,002 2023 754 Thereafter 1,595 Total $ 9,138 The Company tests goodwill for impairment on an annual basis, or more often if events or circumstances indicate that there may be impairment of goodwill. The Company operates in two reporting segments, Restaurant/Retail and Government. Goodwill impairment testing is performed at the reporting unit level. Goodwill is assigned to a specific reporting unit at the date the goodwill is initially recorded. Once goodwill has been assigned to a specific reporting segment, it no longer retains its association with a particular acquisition, and all of the activities within the reporting unit, whether acquired or organically grown, are available to support the value of the goodwill. The amount of goodwill carried by the Restaurant/Retail and Government reporting segments was $13.4 million and $11.1 million at September 30, 2019 and December 31, 2018 , respectively. The Company recognized additions to goodwill as part of the 3M acquisition as indicated in Note 3. No impairment charges were recorded for the period ended September 30, 2019 and year ended December 31, 2018 . Approximately $2.8 million in net software costs were reclassified on the balance sheet to "Asset held for sale" as indicated in Note 4 during the second quarter of 2019 .

Debt Disclosure [Abstract]
Convertible Senior Notes	Convertible Senior Notes On April 15, 2019, the Company sold $80.0 million aggregate principal amount of 4.500% Convertible Senior Notes due 2024 (the "Notes"). The Notes were sold pursuant to an indenture, dated April 15, 2019, between the Company and The Bank of New York Mellon Trust Company, N.A. (“Trustee”), referred to herein as the “Indenture.” The Notes are senior, unsecured obligations of the Company. The Notes pay interest at a rate equal to 4.500% per year. Interest on the Notes is payable semiannually in arrears on April 15 and October 15 of each year, beginning October 15, 2019. Interest accrues on the Notes from the last date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from April 15, 2019. Unless earlier converted, redeemed or repurchased, the Notes mature on April 15, 2024. The implied estimated effective rate of the liability component of the Notes is 10.24% . The Notes are convertible into Company common stock at an initial conversion rate of 35.0217 shares per $1,000 principal amount of Notes, subject to adjustment upon certain events. The Notes are convertible, in whole or in part, at the option of the holder, at any time prior to the close of business on the business day immediately preceding October 15, 2023, but only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2019 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than 130% of the conversion price on such trading day; (2) during the five consecutive business day period immediately after any five consecutive trading day period (the five consecutive trading day period being referred to as the ‘‘measurement period’’) in which the trading price per $1,000 principal amount of the Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on such trading day; (3) upon the occurrence of certain specified corporate events, including fundamental changes (as described in the Indenture); or (4) if the Company calls the Notes for redemption. In addition, regardless of the foregoing circumstances, holders may convert their Notes at any time on or after October 15, 2023 until the close of business on the second business day immediately preceding the maturity date of the Notes. Upon conversion, the Company may elect to settle by paying or delivering either solely cash, shares of Company common stock or a combination of cash and shares of common stock. In accordance with ASC 470-20, the initial measurement of the Notes at fair value resulted in a liability of $62.4 million , as such, the calculated discount resulted in an implied value of the convertible feature recognized in Capital in excess of Par Value of $17.6 million . This resulted in a $0.7 million and $1.3 million increase reflected in interest expense, in the Company's consolidated statements of operations for the three and nine months ended September 30, 2019 , respectively. Issuance costs for the transaction amounted to $4.9 million and were allocated to components on a ratable basis as follows; Capital in excess of Par Value, $1.1 million , and Long-term Debt, $3.8 million . The Indenture contains covenants that, among other things, restricts the Company’s ability to merge, consolidate or sell, or otherwise dispose of, substantially all of its assets. These limitations are subject to a number of important qualifications and exceptions. The Indenture contains customary Events of Default (as defined in the Indenture), including default in the event the Company fails to pay interest on the Notes when due, and such failure continues for 30 days, or the Company fails to pay the principal of the Notes when due, including at maturity, upon redemption or otherwise; failure to comply with covenants and other obligations under the Indenture, including delivery of required notices and obligations in connection with conversion, in certain cases subject to notice and grace periods; payment defaults and accelerations with respect to other indebtedness of the Company and its significant subsidiaries in the aggregate principal amount of $10.0 million or more; failure by the Company or its significant subsidiaries to pay certain final judgments aggregating in excess of $10.0 million within 60 consecutive days of such final judgment; and specified events involving bankruptcy, insolvency or reorganization of the Company or its significant subsidiaries. Upon an Event of Default, the trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare all the Notes to be due and payable immediately. In the case of Events of Default relating to bankruptcy, insolvency or reorganization, all outstanding Notes will become due and payable immediately without further action or notice. In connection with the sale of the Notes, the Company recorded an income tax benefit of $4.1 million as a discrete item for the three and nine months ended September 30, 2019 as a result of the creation of a deferred tax liability associated with the portion of the Notes that was classified within stockholders' equity. While GAAP requires the offset of the deferred tax liability to be recorded in additional paid-in capital, consistent with the equity portion of the Notes, the creation of the deferred tax liability produced evidence of recoverability of deferred tax assets which resulted in the release of a valuation allowance, totaling $4.1 million , reflected as an income tax benefit in the current year. The following table summarizes information about the equity and liability components of the Notes (in thousands): September 30, 2019 Principal amount of 2024 Notes outstanding $ 80,000 Unamortized discount (including unamortized debt issuance cost) (19,863 ) Total long-term portion of notes payable $ 60,137 Equity component of notes $ 17,624 Less: Deferred tax liability (4,065 ) Less: Issuance costs (1,094 ) Capital in excess of Par Value $ 12,465

Earnings Per Share [Abstract]
Net loss per share	Net loss per share Earnings per share are calculated in accordance with ASC Topic 260, which specifies the computation, presentation and disclosure requirements for earnings per share (EPS). It requires the presentation of basic and diluted EPS. Basic EPS excludes all dilution and is based upon the weighted average number of shares of common stock outstanding during the period. Diluted EPS reflects the potential dilution that would occur if convertible securities or other contracts to issue common stock were exercised. For the nine months ended September 30, 2019 , there were 590,000 anti-dilutive stock options outstanding compared to zero as of September 30, 2018 . The potential effect of the conversion feature with respect to the Notes (See Note 9 - Convertible Senior Notes) was excluded from the diluted net loss per share as of September 30, 2019 as the Company's closing stock price on June 28, 2019 (the last trading day before September 30, 2019 ) did not exceed the initial conversion price of $28.55 per share. The potential shares from the Notes at the initial conversion rate was approximately 2,801,736 and they were considered anti-dilutive using the if-converted method. The following is a reconciliation of the weighted average of shares of common stock outstanding for the basic and diluted EPS computations (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Net loss $ (5,902 ) $ (16,704 ) $ (9,740 ) $ (17,959 ) Basic: Shares outstanding at beginning of period 16,290 15,993 16,085 15,949 Weighted average shares issued/(repurchased) during the period, net 10 78 1 84 Weighted average common shares, basic 16,300 16,071 16,086 16,033 Net loss per common share, basic $ (0.36 ) $ (1.04 ) $ (0.61 ) $ (1.12 ) Diluted: Weighted average common shares, basic 16,300 16,071 16,086 16,033 Dilutive impact of stock options and restricted stock awards — — — — Weighted average common shares, diluted 16,300 16,071 16,086 16,033 Net loss per common share, diluted $ (0.36 ) $ (1.04 ) $ (0.61 ) $ (1.12 )

Contingencies	Contingencies The Company is subject to legal proceedings, which arise in the ordinary course of business. Additionally, U.S. Government contract costs are subject to periodic audit and adjustment. In 2016, the Company's Audit Committee commenced an internal investigation into conduct at the Company's China and Singapore offices and voluntarily notified the SEC and the U.S. Department of Justice ("DOJ") of the internal investigation. On May 1, 2017 the Company received a subpoena from the SEC for documents relating to the internal investigation. Following the conclusion of the Audit Committee's internal investigation, the Company voluntarily reported the relevant findings of the investigation to the China and Singapore authorities. During the three and nine months ended September 30, 2019 , the Company recorded $0.1 million and $0.4 million of expenses relating to the internal investigation, including expenses of outside legal counsel and forensic accountants, compared to $0.3 million and $0.9 million for the three and nine months ended September 30, 2018 . In early April 2019, the SEC notified the Company that based on current information, it did not intend to recommend an enforcement action against the Company; shortly, thereafter, the DOJ advised that it did not intend to separately proceed; the Company is cooperating with the China and Singapore authorities. The Company is currently not able to predict what actions these authorities might take, or what the likely outcome of any such actions might be, or estimate the range of reasonably possible fines or penalties, which may be material. The China and Singapore authorities have a broad range of civil and criminal sanctions, and the imposition of fines or penalties could have a material adverse effect on the Company’s business, prospects, reputation, financial condition, results of operations or cash flows.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments have been recorded at fair value using available market information and valuation techniques. The fair value hierarchy is based upon three levels of input, which are: Level 1 — quoted prices in active markets for identical assets or liabilities (observable) Level 2 — inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in inactive markets, or other inputs that are observable market data for essentially the full term of the asset or liability (observable) Level 3 — unobservable inputs that are supported by little or no market activity, but are significant to determining the fair value of the asset or liability (unobservable) The Company’s financial instruments primarily consist of cash and cash equivalents, trade receivables, trade payables, debt instruments and deferred compensation assets and liabilities. The carrying amounts of cash and cash equivalents, trade receivables and trade payables as of September 30, 2019 and December 31, 2018 were considered representative of their fair values. The estimated fair value of the Company’s line of credit on December 31, 2018 was based on variable and fixed interest rates on such respective dates and approximates their respective carrying values at September 30, 2019 and December 31, 2018 . The estimated fair value of the Notes was $88.6 million at September 30, 2019 . The deferred compensation assets and liabilities primarily relate to the Company’s deferred compensation plan, which allows for pre-tax salary deferrals for certain key employees. Changes in the fair value of the deferred compensation liabilities are derived using quoted prices in active markets of the asset selections made by the participants. The deferred compensation liabilities are classified within Level 2, the fair value classification as defined under FASB ASC 820, Fair Value Measurements, because their inputs are derived principally from observable market data by correlation to the hypothetical investments. The Company holds insurance investments to partially offset the Company’s liabilities under its deferred compensation plan, which are recorded at fair value each period using the cash surrender value of the insurance investments. The amounts owed to employees participating in the deferred compensation plan at September 30, 2019 was $3.2 million compared to $3.4 million at December 31, 2018 and is included in other long-term liabilities on the balance sheets. Under the stock purchase agreement governing the Brink Acquisition, in the event certain defined revenues were determined to have been achieved in 2015, 2016, 2017 and 2018 ("contingent consideration period"), the Company would be obligated to pay additional purchase price consideration ("Brink Earn Out"). The fair value of the Brink Earn Out was estimated using a discounted cash flow method, with significant inputs not observable in the market and thus represent a Level 3 fair value measurement as defined in ASC 820, Fair Value Measurements and Disclosures. The significant inputs in the Level 3 measurement not supported by market activity included the Company’s probability assessments of expected future cash flows related to the Brink Acquisition during the contingent consideration period, appropriately discounted considering the uncertainties associated with the Brink Earn Out obligation. Any change in the fair value adjustment was recorded in the earnings of that contingent consideration period. For the $2.6 million of Brink Earn Out targets achieved during the 2018 contingent consideration period, the Company paid the amount in full in March 2019. The following table presents a summary of changes in fair value of the Company’s Level 3 assets and liabilities that are measured at fair value on a recurring basis, and are recorded as a component of other long-term liabilities on the consolidated balance sheet (in thousands): Level 3 Inputs Liabilities Balance at December 31, 2018 $ 2,550 New level 3 liability — Total gains (losses) reported in earnings — Settlement of Level 3 liabilities (2,550 ) Balance at September 30, 2019 $ —
