Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization comScore, Inc., together with its consolidated subsidiaries (collectively, "Comscore" or the "Company"), headquartered in Reston, Virginia, is a global information and analytics company that measures audiences, consumer behavior and advertising across media platforms. Operating segments are defined as components of a business that can earn revenues and incur expenses for which discrete financial information is available that is evaluated on a regular basis by the chief operating decision maker ("CODM"). The Company’s CODM is its principal executive officer, who decides how to allocate resources and assess performance. The Company has one operating segment. A single management team reports to the CODM, who manages the entire business. The Company’s CODM reviews consolidated results of operations to make decisions, allocate resources and assess performance and does not evaluate the profit or loss from any separate geography or product line. On March 31, 2019, Bryan Wiener resigned as the Company's Chief Executive Officer and director and Sarah Hofstetter resigned as the Company's President, effective immediately. On the same day, the Company appointed Dale Fuller as Interim Chief Executive Officer, and Mr. Fuller assumed the role of CODM. Uses and Sources of Liquidity and Management’s Plans The Company’s primary need for liquidity is to fund working capital requirements of its businesses, capital expenditures and for general corporate purposes. Since 2017, the Company has implemented certain organizational restructuring plans to reduce staffing levels, exit certain geographic regions, and rationalize its leased properties, to enable the Company to decrease its global costs, more effectively align resources to business priorities, and maintain compliance with its financial covenants (described below). For additional information, refer to Footnote 13 , Organizational Restructuring . To increase the Company’s available working capital, during 2018, the Company entered into certain agreements with funds affiliated with or managed by Starboard Value LP (collectively, "Starboard"), pursuant to which the Company issued and sold to Starboard a total of $204.0 million in senior secured convertible notes as well as warrants to purchase shares of the Company's common stock, par value $0.001 per share (the "Common Stock") in exchange for $100.0 million in cash and 4,000,000 shares of Common Stock. The convertible notes contain certain affirmative and restrictive covenants with which the Company must comply, including covenants with respect to limitations on additional indebtedness and liens and maintenance of certain minimum cash balances, which will increase from $20.0 million to $40.0 million on the date the Company files its Form 10-Q for the quarterly period ended June 30, 2019. Interest on the convertible notes is payable, at the option of the Company, in cash or, subject to certain conditions, through the issuance by the Company of additional shares of Common Stock. For the interest payments due on April 1, 2019 and July 1, 2019, the Company elected to pay in shares of Common Stock. For additional information, refer to Footnote 5 , Long-term Debt . On June 26, 2019, in order to increase liquidity and maintain compliance with the minimum cash balances covenant described above, the Company issued 2,728,513 shares of Common Stock and four series of warrants in a private placement to CVI Investments, Inc. ("CVI") in exchange for gross cash proceeds of $20.0 million . In connection with the private placement, the Company agreed to a 105 -day lock-up period related to any future offering of equity or equity-linked securities and also agreed to provide certain registration rights. For additional information, refer to Footnote 11 , Stockholders' Equity . As of June 30, 2019 , the Company was in compliance with its covenants under the Starboard convertible notes. Based on management's current plans, including actions within management's control, the Company does not anticipate any breach of these covenants that would result in an event of default under the convertible notes.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned domestic and foreign subsidiaries. All intercompany transactions and balances are eliminated upon consolidation. Reclassification Certain amounts in the prior year financial statements have been reclassified to conform to the current quarter presentation. Specifically, current deferred rent, accrued litigation settlements and current capital lease obligations have been aggregated within other current liabilities on the Condensed Consolidated Balance Sheets. Non-current capital lease obligations have been aggregated within other non-current liabilities on the Condensed Consolidated Balance Sheets. Unaudited Interim Financial Information The interim Condensed Consolidated Financial Statements included in this quarterly report have been prepared by the Company and are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The interim Condensed Consolidated Financial Statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The condensed consolidated results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2019 or thereafter. All references to June 30, 2019 and 2018 in the Notes to Condensed Consolidated Financial Statements are unaudited. Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and the measurement of: management's standalone selling price, principal versus agent revenue recognition, determination of performance obligations, determination of transaction price, including the determination of variable consideration and allocation of transaction price to performance obligations, deferred tax assets and liabilities, including the identification and quantification of income tax liabilities due to uncertain tax positions, the valuation and recoverability of goodwill and intangible assets, the determination of appropriate discount rates for lease accounting, the probability of exercising either lease renewal or termination clauses, the assessment of potential loss from contingencies, the valuation of assets and liabilities acquired in a business combination, the fair value determination of financing derivative liabilities and warrants, the allowance for doubtful accounts, and valuation of options, performance-based and market-based stock awards. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. The Company evaluates its estimates and assumptions on an ongoing basis. Goodwill Goodwill is evaluated for impairment at least annually, as of October 1, by comparing the fair value of a reporting unit to its carrying value including goodwill recorded by the reporting unit. In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, Simplifying the Test for Goodwill Impairment , which eliminated the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, 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 and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the impairment loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the standard as of September 30, 2018. The Company has a single reporting unit. Accordingly, the impairment assessment for goodwill is performed at the enterprise level. Goodwill is reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company initially assesses qualitative factors to determine if it is necessary to perform the goodwill impairment review. Goodwill is reviewed for impairment if, based on an assessment of the qualitative factors, it is determined that it is more likely than not that the fair value of its reporting unit is less than its carrying value, or the Company decides to bypass the qualitative assessment. The carrying value of the reporting unit is reviewed utilizing a discounted cash flow model, and a market value approach is utilized to supplement the discounted cash flow model. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values. Additionally, the Company considers income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The Company monitors for events and circumstances that could negatively impact the key assumptions in determining fair value, including long-term revenue growth projections, profitability, discount rates, volatility in the Company's market capitalization, and general industry, market and macro-economic conditions. The Company completed its annual analysis for the year ended December 31, 2018 and determined that there was no impairment of goodwill at that time. The Company performed an interim analysis as of June 30, 2019 and determined that goodwill was then impaired. Refer to Footnote 4 , Goodwill and Intangible Assets for further information. Impairment of Long-Lived Assets The Company's long-lived assets consist of property and equipment and finite-lived intangible assets. The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of such assets may not be recoverable. If an indication of impairment is present, the Company compares the estimated undiscounted future cash flows to be generated by the asset group to its carrying amount. Recoverability measurement and estimation of undiscounted cash flows are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the undiscounted future cash flows are less than the carrying amount of the asset group, the Company records an impairment loss equal to the excess of the asset group's carrying amount over its fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. There were no impairment charges recognized during the year ended December 31, 2018. The Company performed an interim analysis as of June 30, 2019, as events or changes in circumstances indicated the carrying value of certain assets may not be recoverable, and determined that the Company's 2015 strategic alliance (the "strategic alliance") with WPP plc and its affiliates ("WPP") was impaired. Refer to Footnote 4 , Goodwill and Intangible Assets for further information. Although the Company believes that the carrying values of its long-lived assets are appropriately stated, changes in strategy or market conditions, significant technological developments or significant changes in legal or regulatory factors could significantly impact these judgments and require adjustments to recorded asset balances. Accounting for Warrants During the period ended June 30, 2019, the Company issued warrants that were determined to be freestanding financial instruments that qualify for liability treatment as a result of a net cash settlement feature associated with a cap on the issuance of shares under certain circumstances. Changes in the fair value of these instruments are immediately recorded in other (expense) income, net in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The fair value of the warrants is determined using a Monte Carlo simulation analysis within an option pricing model. The fair value estimate is determined using an estimate for the Company's credit rating, probability of change of control, dividend yield, risk-free rate, remaining term of the warrants and volatility. The fair values of the Company's warrants are estimated using forward projections of stock issuances with relative certainty and estimated cash payments at each exercise date discounted back to the valuation date with the remaining term of the related warrant. The primary sensitivity in the valuation of each warrant liability is driven by the Common Stock price at the measurement date and the observable volatility of the Common Stock. Cost-Method Investment As of June 30, 2019 and December 31, 2018, the Company had one cost-method investment in common stock of an entity. The investment in equity securities is measured at fair value and is included in other non-current assets in the Condensed Consolidated Balance Sheets. Gains or losses related to the change in the fair value of the securities are recorded in other (expense) income, net within the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company sold its investment in equity securities in July 2019 for gross cash proceeds of $3.1 million . Because changes in the equity security’s fair value are reported in earnings as they occur, the sale of an equity security does not result in a gain or loss to earnings. Other (Expense) Income, Net The following is a summary of other (expense) income, net: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2019 2018 2019 2018 Change in fair value of financing derivatives $ (3,000 ) $ (2,280 ) $ 1,100 $ (4,460 ) Change in fair value of investment in equity securities (304 ) 714 (2,016 ) 265 Transition services agreement income — 2,182 534 4,847 Other 223 191 270 232 Total other (expense) income, net $ (3,081 ) $ 807 $ (112 ) $ 884 Loss Per Share Basic net loss per common share excludes dilution for potential Common Stock issuances and is computed by dividing net loss by the weighted-average number of shares of Common Stock outstanding for the period. 250,000 shares of Common Stock issuable upon the exercise of warrants held by Starboard ("penny warrants") were included in the number of outstanding shares used for the computation of basic net loss per share prior to the exercise of those warrants on April 3, 2019. In periods where the Company reports a net loss, the effect of anti-dilutive stock options, stock appreciation rights, restricted stock units, senior secured convertible notes and warrants are excluded and diluted net loss per share is equal to basic loss per share. The following is a summary of the Common Stock equivalents for the securities outstanding during the respective periods that have been excluded from the computation of diluted net loss per common share, as their effect would be anti-dilutive: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Stock options, stock appreciation rights, restricted stock units, senior secured convertible notes and warrants 9,209,577 8,857,858 8,511,550 7,874,656 Leases The Company applies the provisions of Accounting Standards Codification ("ASC") 842, Leases . The Company's lease portfolio is comprised of three major classes. Real estate leases, which are the majority of the Company's leased assets, are accounted for as operating leases. Computer equipment and automobile leases, which comprise the remaining two major lease classes in the Company's portfolio, are generally accounted for as finance leases. The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Right-of-use ("ROU") assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. Operating ROU assets also include the impact of any lease incentives. For any leases in which an asset is not specifically identified, the Company performs a discrete analysis to identify whether there is an implicitly identified asset based on the contractual or other known requirements, such as the presence of substantive substitution rights on the part of the supplier or the right of the Company to sublease the asset. As part of this analysis, the Company also determines whether there are any restrictions on the use of the asset placed on the Company that are not considered protective rights on the part of the supplier and thus would allow the Company to assume which specific assets have been identified. The Company identifies separate lease and non-lease components within the contract. Non-lease components primarily include payments for common-area maintenance and management charges. The Company has elected to combine lease and non-lease payments and account for them together as a single lease component, which increases the amount of the Company's ROU assets and lease liabilities. The interest rate used to determine the present value of the future lease payments is the Company's incremental borrowing rate, because the interest rate implicit in the Company's leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The Company's current discount rates range from 12% to 15% depending on the term of the arrangement. The Company's lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company considers contractual-based factors such as the nature and terms of the renewal or termination, asset-based factors such as physical location of the asset and entity-based factors such as the importance of the leased asset to the Company's operations to determine the lease term. The Company generally uses the base, non-cancelable, lease term when determining the ROU assets and lease liabilities. Payments under the Company's lease arrangements are primarily fixed; however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the measurement of ROU assets and lease liabilities. These amounts include payments affected by changes in the Consumer Price Index and payments for common-area maintenance, real estate taxes and utilities, which are based on usage or performance. Operating leases are included in operating ROU assets, current operating lease liability, and non-current operating lease liability in the Condensed Consolidated Balance Sheets. The Company recognizes lease expense for its operating leases on a straight-line basis over the term of the lease. Finance lease activity is included in property and equipment, net; current finance lease liabilities are aggregated into other current liabilities; and non-current finance lease obligations are aggregated in other non-current liabilities in the Company's Condensed Consolidated Balance Sheets. Finance ROU assets are amortized on a straight-line basis over their estimated useful lives. Income from subleased properties is recognized on a straight-line basis and presented as a reduction of general and administrative expense in the Company's Condensed Consolidated Statement of Operations. In addition to sublease rent, variable non-lease costs such as common-area maintenance and utilities are charged to subtenants over the duration of the lease for their proportionate share of these costs. These variable non-lease income receipts are recognized in operating expenses as a reduction to costs incurred by the Company in relation to the head lease. The Company determines the nature of a sale-leaseback transaction based on the determination of whether the transaction qualifies as a sale and whether there is a transfer in the control of assets. If the transaction does not qualify as a sale, the Company recognizes the transaction as a failed sale-leaseback transaction (financing arrangement). The Company records a financing obligation, and the assets that are included in the failed sale-leaseback transaction remain on the Condensed Consolidated Balance Sheet until the end of the lease term. Change in Accounting Policy The Company adopted ASC 842, with a date of initial application of January 1, 2019, using the modified retrospective transition method with optional transition relief, under which the Company did not restate prior comparative periods and instead recorded an adjustment to stockholders' equity as of the date of initial implementation for the cumulative impact of adoption. As part of the transition, the Company implemented new internal controls and key system functionality to enable the preparation of financial information on adoption, and elected the following practical expedients: • Not to reassess whether any expired or existing contracts are or contain leases. • Not to reassess the lease classification for any expired or existing leases. • Not to reassess initial direct costs for any existing leases. • The hindsight practical expedient in determining the lease term. • The practical expedient whereby the lease and non-lease components will not be separated for all classes of assets. • Not to record ROU assets and corresponding lease liabilities with a lease term of 12 months or less. The Company has elected to net its sublease exit liabilities recognized under ASC 420, Exit or Disposal Cost Obligations as an adjustment to the opening ROU asset for the corresponding head lease established upon the adoption of ASC 842. Sublease exit liabilities had a carrying value of $2.5 million as of December 31, 2018. Upon adoption, ASC 842 had an impact on the Condensed Consolidated Balance Sheets, but did not have an impact on its Condensed Consolidated Statement of Operations. The adoption of ASC 842 impacted the Company's previously reported results as follows: (In thousands) As previously reported as of December 31, 2018 New lease standard adjustments As adjusted as of January 1, 2019 Operating right-of-use assets $ — $ 42,472 $ 42,472 Property and equipment, net 27,339 (203 ) 27,136 Current capital lease obligations 2,421 (161 ) 2,260 Current restructuring accrual 5,479 (708 ) 4,771 Current deferred rent 1,884 (1,884 ) — Current operating lease liabilities — 7,846 7,846 Non-current restructuring accrual 1,810 (1,810 ) — Non-current deferred rent 10,304 (10,304 ) — Non-current capital lease obligations 1,182 3 1,185 Non-current operating lease liabilities — 49,333 49,333 Stockholders' equity 551,567 (46 ) 551,521 Accounting Standards Recently Adopted In July 2017, the FASB issued ASU 2017-11, Earnings Per Share, Distinguishing Liabilities from Equity; Derivatives and Hedging . This update was issued to address complexities in accounting for certain equity-linked financial instruments containing down round features. The amendments in ASU 2017-11 change the classification analysis of these financial instruments (or embedded features) so that equity classification is no longer precluded. The amendments in ASU 2017-11 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This update was issued to allow companies to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. Companies that elect to reclassify these amounts must reclassify stranded tax effects for all items accounted for in accumulated other comprehensive income. The amendments in ASU 2018-02 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Early adoption is permitted. Upon adoption of the standard, the Company did not elect to reclassify stranded tax effects to retained earnings. The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting. This update was issued to allow companies to account for share-based payment transactions with non-employees in the same way as share-based payment transactions with employees, with the main differences being the accounting for attribution and a contractual term election for valuing non-employee equity share options. The amendments in ASU 2018-07 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Per ASU 2018-07, this update should be applied on a modified retrospective basis via a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Early adoption is permitted only if the Company has adopted ASC 606, Revenue from Contracts with Customers . The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2019, including interim reporting periods within those annual periods. Early adoption is permitted. The Company early adopted this standard, effective January 1, 2019, on a prospective basis. The adoption did not have an impact on the Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) , which removes and modifies certain disclosure requirements under Topic 820. The amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt any removed or modified disclosures upon issuance of the update and to delay adoption of the additional disclosures until their effective date. The Company is evaluating the impact to its Condensed Consolidated Financial Statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets As of June 30, 2019, the Company concluded that it was more likely than not that the estimated fair value of its reporting unit was less than its carrying value. In its assessment, the Company considered the sustained decline in the Company's stock price and market capitalization, changes in management, and lower revenue, among other factors. Accordingly, the Company performed a quantitative goodwill impairment test as of June 30, 2019, relying in part on the work of an independent valuation firm engaged by the Company to provide inputs as to the fair value of the reporting unit and to assist in the related calculations and analysis. The fair value of the reporting unit was determined using a discounted cash flow model, supported by a market approach. The Company's reporting unit failed the goodwill impairment test; and as a result the Company recorded a $224.3 million impairment charge for the three months ended June 30, 2019. In addition, the Company recorded a $17.3 million impairment charge related to its strategic alliance intangible asset for the three months ended June 30, 2019. Changes in the Company's projected revenue in certain non-U.S. geographic markets due to the changing international competitive landscape as well as significant reductions in international staffing during the quarter, resulted in a change in the Company's long-term view of the viability of the intangible asset. As such, the Company's assessment yielded that the benefit of the alliance would not be realized. The fair value of the strategic alliance intangible asset was estimated using an income approach resulting in an impairment charge for the full carrying value of the long-lived asset of $17.3 million . The change in the carrying value of goodwill is as follows: (In thousands) Balance as of December 31, 2017 $ 642,424 Translation adjustments (1,233 ) Balance as of December 31, 2018 $ 641,191 Translation adjustments (144 ) Impairment charge (224,272 ) Balance as of June 30, 2019 Goodwill 641,047 Accumulated impairment (224,272 ) Total $ 416,775 The carrying values of the Company's amortizable intangible assets are as follows: June 30, 2019 December 31, 2018 (In thousands) Gross Carrying Amount Accumulated Amortization Impairment Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Acquired methodologies/technology $ 148,374 $ (76,754 ) $ — $ 71,620 $ 148,374 $ (66,690 ) $ 81,684 Strategic alliance 30,100 (12,792 ) (17,308 ) — 30,100 (11,288 ) 18,812 Customer relationships 40,142 (23,105 ) — 17,037 40,127 (20,338 ) 19,789 Intellectual property 14,366 (12,122 ) — 2,244 14,366 (11,905 ) 2,461 Trade names 775 (670 ) — 105 775 (636 ) 139 Acquired software 9,287 (7,089 ) — 2,198 9,287 (5,531 ) 3,756 Other 600 (346 ) — 254 600 (296 ) 304 Total intangible assets $ 243,644 $ (132,878 ) $ (17,308 ) $ 93,458 $ 243,629 $ (116,684 ) $ 126,945 Amortization expense related to intangible assets was $8.1 million and $8.3 million for the three months ended June 30, 2019 and 2018, respectively.

Long-term Debt

Long-term Debt	6 Months Ended

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt Issuance and Sale of Initial Notes On January 16, 2018 , the Company entered into certain agreements with Starboard, pursuant to which, among other things, the Company issued and sold to Starboard $150.0 million of senior secured convertible notes (the "Initial Notes") in exchange for $85.0 million in cash and 2,600,000 shares of Common Stock valued at $65.0 million . Based upon the fair value of the Common Stock on the closing date of the Initial Notes issuance, January 16, 2018 , which was $24.45 per share, the difference of $1.4 million was recorded as an issuance discount to the Initial Notes. The Company also granted to Starboard an option (the "Notes Option") to acquire up to an additional $50.0 million in senior secured convertible notes (the "Option Notes" and together with the Initial Notes, the "Notes") and agreed to grant Starboard warrants to purchase 250,000 shares of Common Stock at a price of $0.01 per share, as adjusted pursuant to the terms of the warrants. The warrants were issued on October 12, 2018 and were exercised in full by Starboard on April 3, 2019 for 323,448 shares of Common Stock. The conversion price for the Notes (the "Conversion Price") is equal to a 30% premium to the volume weighted average trading prices ("VWAP") of the Common Stock on each trading day during the 10 consecutive trading days commencing on January 16, 2018 , subject to a Conversion Price floor of $28.00 per share. In accordance with the foregoing, the Conversion Price was set at $31.29 . The Notes mature on January 16, 2022 . Based upon the determination of the Conversion Price, interest on the Notes accrued at 6.0% per year through January 30, 2019 , when the interest rate reset to 12.0% per year through January 30, 2020. On each of January 30, 2020 and February 1, 2021 , the interest rate on the Notes will reset, and interest will thereafter accrue at a minimum of 4.0% per year and a maximum of 12.0% per year, based upon the then-applicable conversion premium in accordance with the terms of the Notes. The interest rate reset feature of the Initial Notes was determined by management to be a derivative instrument that qualifies for liability treatment. The derivative instrument is initially measured at fair value and classified as a liability on the balance sheet, with subsequent changes in fair value being recorded in earnings. To determine the fair value of the interest rate reset feature, management utilizes a "with-and-without" convertible bond model, modified to incorporate the interest rate reset feature. Interest on the Notes is payable on a quarterly basis in arrears from April 1, 2018, at the option of the Company, in cash, or, subject to certain conditions, through the issuance by the Company of additional shares of Common Stock ("PIK Interest Shares"). Any PIK Interest Shares so issued will be valued at the arithmetic average of the VWAP of the Common Stock on each trading day during the 10 consecutive trading days ending immediately preceding the applicable interest payment date. On April 1, 2019, the Company paid its quarterly accrued interest liability on the Notes for the first quarter through the issuance of 243,261 PIK Interest Shares. On July 1, 2019, the Company paid its quarterly accrued interest liability on the Notes for the second quarter through the issuance of 856,289 PIK Interest Shares. The accrued interest liability of $6.1 million was classified within other non-current liabilities in the Condensed Consolidated Financial Statements as of June 30, 2019. The Initial Notes contain redemption provisions whereby, upon the occurrence of certain change of control transactions, a holder would have the right to require the Company to redeem all or any portion of such holder's outstanding Initial Notes for cash at a price determined in accordance with the terms of the Initial Notes. Management evaluated this change of control redemption feature and determined that it represented an embedded derivative that must be bifurcated and accounted for separately from the Initial Notes. The change of control derivative is treated as a liability, initially measured at fair value with subsequent changes in fair value recorded in earnings. Management utilizes a probability-adjusted binomial lattice model to determine the fair value of the change of control derivative. The cash proceeds and Common Stock received by the Company in exchange for the Initial Notes were net of a $20.1 million issuance discount and $4.6 million in third party debt issuance costs. The Notes also contain certain affirmative and restrictive covenants with which the Company must comply, including (i) covenants with respect to limitations on additional indebtedness, (ii) limitations on liens, (iii) limitations on certain payments, (iv) maintenance of certain minimum cash balances (which will increase to $40.0 million on the date the Company files its Form 10-Q for the quarterly period ended June 30, 2019), and (v) the timely filing of certain disclosures with the SEC. The Company is in compliance with its Notes covenants as of the date of these financial statements. Issuance and Sale of Option Notes On May 17, 2018 , the Notes Option was exercised by Starboard, pursuant to which the Company issued and sold to Starboard $50.0 million of Option Notes in exchange for $15.0 million in cash and 1,400,000 shares of Common Stock valued at $35.0 million . Based upon the fair value of the Common Stock on the closing date of the Option Notes issuance, May 17, 2018 , which was $21.75 per share, the difference of $4.6 million was recorded as an issuance discount to the Option Notes. The Option Notes have the same terms, including maturity, interest rate, convertibility, and security, as the Initial Notes, except with regard to the date from which interest began to accrue, which was May 17, 2018 . The interest rate reset feature of the Option Notes was determined by management to be a derivative instrument that qualifies for liability treatment. The derivative instrument is initially measured at fair value and classified as a liability on the balance sheet, with subsequent changes in fair value being recorded in earnings. To determine the fair value of the interest rate reset feature, management utilizes a "with-and-without" convertible bond model, modified to incorporate the interest rate reset feature. The Option Notes contain redemption provisions whereby, upon the occurrence of certain change of control transactions, a holder would have the right to require the Company to redeem all or any portion of such holder's outstanding Option Notes for cash at a price determined in accordance with the terms of the Option Notes. Management evaluated this change of control redemption feature and determined that it represented an embedded derivative that must be bifurcated and accounted for separately from the Option Notes. The change of control derivative is treated as a liability, initially measured at fair value with subsequent changes in fair value recorded in earnings. Management utilizes a probability-adjusted binomial lattice model to determine the fair value of the change of control derivative. The cash proceeds and Common Stock received by the Company in exchange for the Option Notes were net of a $3.1 million issuance discount and $0.2 million in third-party debt issuance costs. Notes Modifications As noted above, the minimum cash balance covenant increases to $40.0 million on the date the Company files its Form 10-Q for the quarterly period ended June 30, 2019. This covenant resulted from modifications that occurred in August 2018 and November 2018, in which the outstanding Notes were amended to reduce and extend, respectively, the requirement to maintain certain minimum cash balances to $20.0 million from the initial requirement of $40.0 million until the date the Company files its Form 10-Q for the quarterly period ended June 30, 2019. In connection with and as consideration for these modifications, the Company issued to Starboard $4.0 million in additional aggregate principal amount of senior secured convertible notes, $3.5 million of which was classified as additional Initial Notes and $0.5 million of which was classified as additional Option Notes. The November 2018 agreement also modified the provisions of the Notes and the Registration Rights Agreement between the Company and Starboard by revising the grace periods during which the Company would not be obligated to keep applicable registration statements available for use by Starboard. The terms of the additional notes are identical to the terms of the Notes, except with regard to the date from which interest began to accrue. The amendments were treated as a modification to the debt agreements, and the costs related to the issuance of the additional notes were combined with the existing unamortized discount of the Notes on the modification date and are amortized to interest expense over the remaining term of the modified debt. The Company's long-term debt as of June 30, 2019 and December 31, 2018 was as follows: As of June 30, 2019 (In thousands, except interest rates) Stated Interest Rate Effective Interest Rate Face Value Issuance Discount Deferred Financing Costs Net Carrying Value Initial Notes, due January 16, 2022 12.0% 18.6% $ 153,500 $ (17,013 ) $ (3,228 ) $ 133,259 Option Notes, due January 16, 2022 12.0% 14.7% 50,500 (2,668 ) (182 ) 47,650 Total $ 204,000 $ (19,681 ) $ (3,410 ) $ 180,909 As of December 31, 2018 (In thousands, except interest rates) Stated Interest Rate Effective Interest Rate Face Value Issuance Discount Deferred Financing Costs Net Carrying Value Initial Notes, due January 16, 2022 6.0% 12.0% $ 153,500 $ (19,627 ) $ (3,724 ) $ 130,149 Option Notes, due January 16, 2022 6.0% 8.5% 50,500 (3,096 ) (211 ) 47,193 Total $ 204,000 $ (22,723 ) $ (3,935 ) $ 177,342 Due to the interest rate reset feature of the Notes, the potential future cash flows associated with the Notes are variable. Accordingly, the accretion schedule of debt discount and the amortization schedule of debt issuance costs are updated annually to reflect periodic changes in the future cash flows using the effective interest rate on a prospective basis. The Company amortized $0.3 million and $0.5 million in debt issuance costs related to the Notes during the three and six months ended June 30, 2019 , respectively. The Company amortized $0.2 million and $0.4 million in debt issuance costs related to the Notes during the three and six months ended June 30, 2018 , respectively. The Company accreted $1.7 million and $3.0 million in issuance discount related to the Notes during the three and six months ended June 30, 2019 , respectively. The Company accreted $1.1 million and $2.0 million in issuance discount related to the Notes during the three and six months ended June 30, 2018 , respectively. The estimated fair value of the Notes, using Level 3 inputs based on interest rates available for debt with terms and maturities similar to the Company's Notes, was $162.1 million as of June 30, 2019 . Potential Rights Offering Under the January 16, 2018 agreements with Starboard, the Company has the right to conduct a rights offering (the "Rights Offering") for up to $150.0 million in senior secured convertible notes ("Rights Offering Notes"). Subject to the terms of the Rights Offering, if undertaken, the Company would distribute to all of the Company's stockholders rights to acquire Rights Offering Notes. Stockholders who elect to participate in the Rights Offering could elect to have up to 30% of the Rights Offering Notes they acquire pursuant thereto delivered through the sale to or exchange with the Company of shares of Common Stock, with the per share value thereof equal to the closing price of the Common Stock on the last trading day immediately prior to the commencement of the Rights Offering. The Rights Offering Notes would be substantially similar to the Notes, except, among other things, with respect to: (i) the date from which interest thereon would begin to accrue and the maturity date thereof (which would be four years from the date of issuance of the Rights Offering Notes) and (ii) the conversion price thereof, which would be equal to 130% of the closing price of the Common Stock on the last trading day immediately prior to the commencement of the Rights Offering (subject to a conversion price floor of $28.00 per share). Starboard also agreed to enter into one or more backstop commitment agreements, pursuant to which Starboard would backstop up to $100.0 million in aggregate principal amount of Rights Offering Notes through the purchase of additional Notes, with such backstop obligation reduced by the amount of Option Notes purchased ( $50.0 million ). The Company is not obligated to undertake the Rights Offering, and the Company does not currently intend to do so. Guarantee and Security of Notes The Notes are guaranteed by certain of the Company’s direct and indirect wholly-owned domestic subsidiaries (the "Guarantors") and are secured by a security interest in substantially all of the assets of the Company and the Guarantors, pursuant to a Guaranty, dated as of January 16, 2018, entered into by the Guarantors, and a Pledge and Security Agreement, dated as of January 16, 2018, among the Company, the Guarantors and Starboard Value and Opportunity Master Fund Ltd. as collateral agent. Registration of Underlying Shares The Company filed a registration statement on Form S-1 with the SEC allowing for the resale of the shares of Common Stock underlying the Notes, potential PIK Interest Shares, and Starboard warrants. In conjunction with this registration, WPP exercised its right to have its shares of Common Stock included in the registration statement. The registration statement on Form S-1 was declared effective as of October 16, 2018. On May 28, 2019, the Company filed a registration statement on Form S-3 with the SEC allowing for the resale of additional shares of Common Stock underlying the Notes and potential PIK Interest Shares. The previously filed registration statement on Form S-1 was amended to convert into a registration statement on Form S-3, and the amendment was declared effective as of June 24, 2019. Letters of Credit On June 1, 2018 , the Company entered into a Security Agreement with Wells Fargo Bank, N.A. to issue standby letters of credit. As of June 30, 2019 , $3.5 million in letters of credit are outstanding and are cash collateralized under the Security Agreement with Wells Fargo Bank, N.A. Failed Sale-Leaseback Transaction In June 2019, the Company entered into a sale-leaseback arrangement with a vendor to provide $4.3 million in cash proceeds for previously acquired computer and other equipment. The arrangement is repayable over a 24 -month term for total consideration of $4.8 million , with control of the equipment transferring to the vendor at the end of the leaseback term. The Company concluded the leaseback would be classified as a financing lease. Therefore, the transaction was deemed a failed sale-leaseback and was accounted for as a financing arrangement. The assets continue to be depreciated over their useful lives, and payments are allocated between interest expense and repayment of the financing liability. The financing obligation is included within other current and other non-current liabilities on the Condensed Consolidated Balance Sheet, with $1.7 million classified as short-term and $2.6 million classified as long-term. Future minimum payments related to the financing obligations under the failed sale-leaseback transaction as of June 30, 2019 are summarized below: (In thousands) Remainder of 2019 $ 1,119 2020 2,239 2021 1,417 Total $ 4,775

(2) The Company's investment in common stock of an entity, which is included in other non-current assets, is valued using a market approach based on the quoted market price of the security. The Company sold a portion of its investment in an equity security during the six months ended June 30, 2019 , with the remainder sold in July 2019. (3) The fair value of the Company's interest rate reset derivative liability is determined using a with-and-without approach, using a standard binomial tree convertible bond model . The fair value estimate is determined using an estimate for the Company's credit rating, the premium attributable to the payment-in-kind feature of the Notes, and premium estimates for company-specific risk factors. The valuation is derived from techniques which utilize unobservable Level 3 inputs. (4) The fair value of the Company's change of control redemption derivative liability is determined using a probability adjusted binomial lattice model. The fair value estimate is determined using an estimate for the probability of change of control of the Company, risk-free rate, and remaining term of the redemption feature. These estimates represent Level 3 inputs within the fair value hierarchy. (5) For more information regarding the valuation method and the estimates for significant unobservable inputs for each of the Level 3 warrants, refer to Footnote 11 , Stockholders' Equity. (6) The strategic alliance with a carrying amount of $17.3 million was written down to a zero fair value as of June 30, 2019, resulting in an impairment charge of $17.3 million , which was included in net loss for the period ended June 30, 2019. (7) Goodwill with a carrying amount of $641.0 million was written down by $224.3 million as of June 30, 2019. The impairment charge of $224.3 million , which was included in net loss for the period ended June 30, 2019, represents the excess of the carrying value of the Company's reporting unit over its estimated fair value. For the quarter ended June 30, 2019, the Company recorded an intangible asset impairment charge of $17.3 million and a goodwill impairment charge of $224.3 million . Refer to Footnote 4 , Goodwill and Intangible Assets . The remeasurement of goodwill and the strategic alliance intangible asset is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed in the determination of the fair values. The Company used a discounted cash flow model to determine the estimated fair value of the reporting unit. A market approach was also utilized to supplement the discounted cash flow model. The Company made estimates and assumptions regarding future cash flows, discount rates, long-term growth rates and market values to determine the reporting unit’s estimated fair value. It is possible that future changes in such circumstances, or in the variables associated with the judgments, assumptions and estimates used in assessing the fair value of the reporting unit, would require the Company to record additional non-cash impairment charges. The fair value of the strategic alliance intangible asset was estimated using an income approach. The Company made estimates and assumptions regarding future cash flows and long-term growth rates to determine the fair value of the intangible asset. The Company did not have any transfers between fair value levels during the periods presented. There were no changes to the Company's valuation methodologies during the three and six months ended June 30, 2019 or 2018 , respectively. The following table presents the changes in the Company's recurring Level 3 fair valued instruments for the six months ended June 30, 2019 and 2018, respectively: (In thousands) Financing Derivative Liabilities Warrants Balance as of December 31, 2018 $ 26,100 $ — Issuance of warrants — 10,798 Total gain included in other (expense) income, net (1) (1,100 ) — Balance as of June 30, 2019 $ 25,000 $ 10,798 (1) Represents $0.5 million gain due to change in fair value of interest rate reset derivative liability and $0.6 million gain due to change in fair value of change of control redemption derivative liability. All gains were recorded in other(expense) income, net in the Condensed Consolidated Statements of Operations and Comprehensive Loss.

All gains and losses were recorded in other (expense) income, net in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The following table displays valuation techniques and the significant unobservable inputs for the Company's Level 3 interest rate reset and change of control redemption liabilities, which are measured at fair value on a recurring basis: Fair value measurements Significant valuation technique Significant unobservable inputs June 30, 2019 December 31, 2018 Interest rate reset derivative liability Discounted cash flow Discount rate 25.0% 25.0% Stock price $5.16 $14.43 Risk-free rate 1.7% 2.5% Volatility 42.2% 43.9% Term 2.54 years 3.04 years Change of control redemption derivative liability Option pricing model Probability 0-10% 0-10% Risk-free rate 1.7% 2.5% The fair values of the Company's financing derivatives are estimated using forward projections and are discounted back at rates commensurate with the remaining term of the related derivative. The primary sensitivity in the interest rate reset derivative liability is driven by the Common Stock price at the measurement date, the observable volatility of the Common Stock, and the discount

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax provision for interim periods is calculated by applying its estimated annual effective tax rate on its projected ordinary book income (loss) before taxes to year-to-date ordinary book income (loss) before taxes. The income tax effects of any extraordinary, significant unusual or infrequent items not included in ordinary book income (loss) are determined separately and recognized in the period in which the items arise. During the three and six months ended June 30, 2019 , the Company recorded an income tax benefit of $4.5 million and $3.3 million , resulting in an effective tax rate of 1.6% and 1.1% , respectively. A deferred income tax benefit of $5.0 million related to the impairment of goodwill is included in these amounts. During the three and six months ended June 30, 2018 , the Company recorded an income tax provision of $2.1 million and $3.5 million , resulting in an effective tax rate of 3.9% and 3.4% , respectively. These effective tax rates differ from the U.S. federal statutory rate primarily due to the effects of foreign tax rate differences, U.S. state legislative changes and changes in the Company’s valuation allowance against its domestic deferred tax assets. As of June 30, 2019 and December 31, 2018 , the Company had unrecognized tax benefits of approximately $2.4 million and $2.5 million , respectively. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Stockholders' Equity

Stockholders' Equity	6 Months Ended

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders' Equity 2019 Issuance and Sale of Common Stock and Warrants On June 23, 2019 , the Company entered into a Securities Purchase Agreement (the "Purchase Agreement") with CVI, pursuant to which CVI agreed to purchase (i) 2,728,513 shares of Common Stock (the "Initial Shares"), at a price of $7.33 per share and (ii) Series A Warrants, Series B-1 Warrants, Series B-2 Warrants and Series C Warrants, for aggregate gross proceeds of $20.0 million (the "Private Placement"). The Private Placement closed on June 26, 2019 (the "Closing Date"). The Series B-1 and Series B-2 Warrants are exercisable by the holders at any time prior to the six- and twelve-month anniversaries of the Closing Date, respectively. The Series B-1 Warrants provide the holders the right to purchase an aggregate of up to 2,347,418 shares of Common Stock at an exercise price equal to $8.52 , and the Series B-2 Warrants provide the holders the right to purchase an aggregate of up to 1,121,076 shares of Common Stock at an exercise price equal to $8.92 . The Series B-1 and B-2 Warrants may be exercised for cash only. If all of the Series B-1 Warrants or Series B-2 Warrants have not been exercised prior to their respective expiration dates, the Company will have the right, subject to prior notice to the holders and certain equity, volume and other conditions, to force the exercise of any unexercised portion of the applicable Series B-1 or B-2 Warrants by such holders. Key conditions that may impact the ability of the Company to force the exercise of these warrants include a $3.96 minimum for the VWAP of the Common Stock on the forced exercise date, a minimum threshold for trading volume, and the maintained effectiveness of a registration statement with the SEC. The forced exercise price for the Series B-1 Warrants will be 85% of the VWAP of the Common Stock as of the date immediately preceding the expiration date of the Series B-1 Warrants (the "Series B-1 Forced Exercise Price"). The forced exercise price for the Series B-2 Warrants will be the lesser of (i) 85% of the VWAP of the Common Stock on the date immediately preceding the expiration date of the Series B-2 Warrants and (ii) the Series B-1 Forced Exercise Price. The Series A Warrants are exercisable for a period of five years from the Closing Date and are exercisable into a number of shares of Common Stock equal to the Initial Shares plus any shares issued pursuant to the exercise of the Series C Warrants (described below). The exercise price for the Series A Warrants is $12.00 . The Series A Warrants may be exercised for cash or through a net settlement feature. The Series C Warrants are partially prepaid warrants (with a nominal remaining exercise price) that are not exercisable before September 21, 2019 and expire 90 days after the first anniversary of the Closing Date. If the VWAP of the Common Stock as of September 20, 2019, discounted by 7.5% , is less than CVI's purchase price for the Initial Shares, then, upon exercise, the Company will be required to issue to CVI a number of shares of Common Stock equal to (i) (x) CVI's purchase price for the Initial Shares divided by (y) 92.5% of the VWAP of the Common Stock as of the date immediately preceding exercise, subject to a floor of 50% of the price per Initial Share, less (ii) the number of Initial Shares issued to CVI on the Closing Date. The exercise prices for the Series A, B-1 and B-2 Warrants are subject to anti-dilution adjustment in certain circumstances. If and to the extent the exercise of any warrants would, together with the issuances of the Initial Shares and the shares issued pursuant to the exercise of any other warrants, result in the issuance of 20% or more of the outstanding Common Stock of the Company on the Closing Date (the "Exchange Cap"), the Company intends to, in lieu of issuing such shares, settle the obligation to issue such shares in cash. In addition, CVI will not have the right to exercise any warrant that would result in CVI beneficially owning more than 4.99% of the outstanding Common Stock after giving effect to such exercise. CVI has the right, in its discretion, to raise this threshold up to 9.99% with 60 days' notice to the Company. If any forced exercise of a Series B-1 or B-2 Warrant would result in CVI beneficially owning more than 4.99% of the outstanding Common Stock, CVI will pay the applicable forced exercise price and no shares of Common Stock will be issued, but instead the aggregate number of shares of Common Stock issuable upon any exercise of the Series C Warrant will increase by an equal amount. Pursuant to the transactions described above, the Company agreed to a 105 -day lock-up period related to any future offering of equity or equity-linked securities and also agreed to provide CVI with registration rights relating to the Initial Shares and any shares issuable upon the exercise of the warrants. On June 26, 2019, the Company filed a prospectus supplement to its effective registration statement on Form S-3 to permit the resale of such shares. Management determined each warrant to be a freestanding financial instrument that qualifies for liability treatment as a result of the net cash settlement feature associated with the Exchange Cap provision. Each warrant is initially measured at fair value and classified as a current liability on the Condensed Consolidated Balance Sheet, with subsequent changes in fair value recorded in earnings. To determine the fair value of each warrant, management utilized a Monte Carlo simulation analysis within an option pricing model using the following key assumptions: • Stock Price : The stock price was measured using the fair value of the Common Stock on the issuance date, June 26, 2019, which was $5.57 per share. • Volatility : The Company determined volatility to be 50.0% based on (i) the historical volatility of the Common Stock daily volume weighted average price with a look-back period commensurate with the term of the warrants and (ii) options-based implied volatility. • Risk-free Rate : Management assumed the risk-free rate to be between 1.74% and 2.12% , based on the U.S. Treasury bonds on the valuation date with terms commensurate with the terms of each warrant. • Dividend Yield : Management assumed the dividend yield to be zero based on the historical payout of the Company. • Term : Management determined the term based on the time period of each warrant's maturity, between six months and five years from the issuance date, June 26, 2019. • Cost of Debt : Management assumed the cost of debt to be between 16.7% and 18.7% based on a synthetic credit rating analysis. • Change of control probability : The Company utilized a range between 0% and 10% to estimate the likelihood of occurrence. The above estimates represent Level 3 inputs within the fair value hierarchy. Based on the option pricing valuation model, the Company determined the fair value of the warrants as of June 26, 2019 and June 30, 2019 to be the following: (in thousands) Warrants Liability Series A Warrant $ 3,862 Series B-1 Warrant 328 Series B-2 Warrant 376 Series C Warrant 6,232 Total $ 10,798 The fair values of the Company's warrants are estimated using forward projections of stock issuances with relative certainty and estimated cash payments at each exercise date discounted back to the valuation date with the remaining term of the related warrant. The primary sensitivity in the valuation of each warrant liability is driven by the Common Stock price at the measurement date and the observable volatility of the Common Stock. The Company recorded $2.8 million in transaction costs, of which $1.2 million was allocated to the warrants liability and recorded in general and administrative expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The remaining transaction costs of $1.6 million were recorded in additional paid-in capital in the Condensed Consolidated Balance Sheet. 2018 Equity and Incentive Compensation Plan The Company's stockholders approved the 2018 Equity and Incentive Compensation Plan (the "2018 Plan") at the Company's 2018 annual meeting of stockholders. Under the 2018 Plan, the Company may grant option rights, appreciation rights, restricted stock awards, restricted stock units, performance shares and performance units up to 10,650,000 shares of Common Stock. The aggregate number of shares of Common Stock available will be reduced by: (i) one share of Common Stock for every one share of Common Stock subject to an award of option rights or appreciation rights granted under the 2018 Plan and (ii) two shares of Common Stock for every one share of Common Stock subject to an award other than option rights or appreciation rights granted under the 2018 Plan. If any award granted under the 2018 Plan (in whole or in part) is cancelled or forfeited, expires, is settled in cash, or is unearned, the shares of Common Stock subject to such award will, to the extent of such cancellation, forfeiture, expiration, cash settlement, or unearned amount, again be available at a rate of one share of Common Stock for every one share of Common Stock subject to awards of option rights or appreciation rights and two shares of Common Stock for every one share of Common Stock subject to awards other than of option rights or appreciation rights. Additionally, if, after December 31, 2017, any shares of Common Stock subject to an award granted under the 2007 Equity Incentive Plan (the "2007 Plan") are forfeited, or an award granted under the 2007 Plan (in whole or in part) is canceled or forfeited, expires, is settled in cash, or is unearned, the shares of Common Stock subject to such award will, to the extent of such cancellation, forfeiture, expiration, cash settlement, or unearned amount, be available for awards under the 2018 Plan at a rate of one share for every one share subject to such award. The Company registered the securities under the 2018 Plan with the SEC effective June 1, 2018. The maximum number of shares available for issuance under the 2018 Plan as of June 30, 2019 is 4,807,850 . Stock Awards On June 5, 2018, the Company's Compensation Committee approved and awarded 2,078,151 restricted stock units ("RSUs") under the 2018 Plan to employees, directors and consultants of the Company that were recommended in 2016, 2017 and 2018. On June 5, 2018, the closing price of Common Stock on Nasdaq was $24.23 . Of these RSUs granted, 1,264,115 vested immediately, of which 229,173 shares were delivered to certain consultants during the three months ended June 30, 2018 . 165,086 of the consultant shares related to the compensation of one of the Company's former chief executive officers as part of his retirement and transition services agreement. Undelivered shares were classified as unvested awards until the date of delivery of the shares underlying these awards. Upon the grant of the awards, the Company recognized $21.1 million in stock-based compensation expense during the three months ended June 30, 2018 . During the six months ended June 30, 2019, the Company's Compensation Committee approved and awarded 884,462 time-based RSUs (of which 206,108 RSUs relate to the settlement of the accrued 2018 annual incentive plan liability) and 300,000 market-based RSUs to employees, directors and consultants of the Company. The time-based RSUs generally vest after one to three years contingent on continued service. Market-based awards vest annually over ten years based on the achievement of certain stock price goals. A summary of the unvested stock awards as of June 30, 2019 and June 30, 2018 is presented below: Unvested Stock Awards Restricted Stock Awards Restricted Stock Units Number of Shares Underlying Awards Weighted Average Grant-Date Fair Value Unvested as of December 31, 2018 — 1,466,135 1,466,135 $ 22.62 Granted — 1,184,462 1,184,462 14.36 Vested and delivered — (598,729 ) (598,729 ) 24.65 Forfeited — (335,403 ) (335,403 ) 19.91 Unvested as of June 30, 2019 — 1,716,465 1,716,465 $ 16.97 Unvested Stock Awards Restricted Stock Awards Restricted Stock Units Number of Shares Underlying Awards Weighted Average Grant-Date Fair Value Unvested as of December 31, 2017 2,125 779,912 782,037 $ 37.22 Granted — 2,078,151 2,078,151 24.07 Vested and delivered (2,125 ) (720,347 ) (722,472 ) 32.74 Forfeited — (15,090 ) (15,090 ) 36.65 Unvested as of June 30, 2018 — 2,122,626 2,122,626 $ 25.29 The weighted-average remaining vesting period for unvested RSUs as of June 30, 2019 was 2.63 years . As of June 30, 2019 , total unrecognized compensation expense related to unvested RSUs was $19.5 million , of which $5.8 million is expected to be recognized in the second half of 2019 . As of June 30, 2018 , total unrecognized compensation expense related to unvested RSUs was $19.2 million . Total unrecognized compensation expense may be increased or decreased in future periods for subsequent grants or forfeitures. Stock Options During the six months ended June 30, 2019 , the Company's Compensation Committee approved and awarded 290,000 stock options under the 2018 Plan to employees and consultants of the Company. The fair value of options at date of grant was estimated using the Black-Scholes method utilizing the following assumptions: Dividend yield 0.00% Expected volatility 44.94 % - 46.16% Risk-free interest rate 2.15 % - 2.72% Expected life of options (in years) 6.25 - 10.0 Dividend yield — The Company has never declared or paid a cash dividend on its Common Stock and has no plans to pay cash dividends in the foreseeable future. Expected volatility — Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company considered the historical volatility of its stock price over a term similar to the expected life of the options in determining expected volatility.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies The Company is involved in various legal proceedings from time to time. The Company establishes reserves for specific legal proceedings when management determines that the likelihood of an unfavorable outcome is probable and the amount of loss can be reasonably estimated. The Company has also identified certain other legal matters where an unfavorable outcome is reasonably possible and/or for which no estimate of possible losses can be made. In these cases, the Company does not establish a reserve until it can reasonably estimate the loss. Legal fees are expensed as incurred. The outcomes of legal proceedings are inherently unpredictable, subject to significant uncertainties, and could be material to the Company's operating results and cash flows for a particular period. Privacy Class Action Litigation On September 11, 2017, the Company and a wholly-owned subsidiary, Full Circle Studies, Inc., ("Full Circle"), received demand letters on behalf of named plaintiffs and all others similarly situated alleging that the Company and Full Circle collected personal information from users under the age of 13 without verifiable parental consent in violation of Massachusetts law and the federal Children’s Online Privacy Protection Act. The letters alleged that the Company and Full Circle collected such personal information by embedding advertising software development kits ("SDKs") in applications created or developed by The Walt Disney Company. The letters sought monetary damages, attorneys’ fees and damages under Massachusetts law. On June 4, 2018, the plaintiffs filed amended complaints with the U.S. District Court for the Northern District of California adding the Company and Full Circle as defendants in a purported class action (captioned Rushing, et al v. The Walt Disney Company, et al., Case No. 3:17-cv-04419-JD) against Disney, Twitter and other defendants, alleging violations of California’s constitutional right to privacy and intrusion upon seclusion law, New York’s deceptive trade practices statute, and Massachusetts’ deceptive trade practices and right to privacy statutes. The complaints allege damages in excess of $5 million , with any award to be apportioned among the defendants. On May 22, 2019, the Court denied the defendants' motion to dismiss the complaints. The Company and Full Circle deny any wrongdoing or liability and intend to vigorously defend against these claims. Although the ultimate outcome of this matter is unknown, the Company believes that a material loss was not probable or estimable as of June 30, 2019 . Securities Class Action Litigation On April 10, 2019, Sergii Bratusov, a purported shareholder of the Company, filed a putative class action complaint against the Company on behalf of all persons and entities that acquired securities of the Company between November 9, 2018 and March 29, 2019. The case, captioned Bratusov v. comScore, Inc., et al. , Case No. 19 Civ. 03210, was filed in the U.S. District Court for the Southern District of New York and also names the Company's Chief Financial Officer, Gregory Fink, and the Company's former Chief Executive Officer, Bryan Wiener, as defendants. The complaint alleges that the Company, Mr. Wiener, and Mr. Fink violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, by allegedly failing to disclose in public statements between November 2018 and March 2019 material information concerning unspecified difficulties implementing the Company's business strategy and the impact of these alleged difficulties on the Company's financial results. The complaint also alleges that Mr. Wiener and Mr. Fink, acting as control persons of the Company, violated Section 20(a) of the Exchange Act in connection with the Company's alleged failure to disclose material information. The complaint seeks a determination of the propriety of the class, compensatory damages and the award of reasonable costs and expenses incurred in the action. The defendants deny any wrongdoing or liability and intend to vigorously defend against these claims. Although the ultimate outcome of this matter is unknown, the Company believes that a material loss was not probable or estimable as of June 30, 2019 . SEC Investigation The SEC is investigating allegations with respect to the Company regarding revenue recognition, internal controls, non-GAAP disclosures, tone at the top and whistleblower retaliation. The SEC has made no decisions regarding this matter including whether any securities laws have been violated. The Company is cooperating fully with the SEC and is seeking to resolve this matter as soon as possible. The Company has accrued a $5.0 million liability in connection with the SEC investigation, which management has determined is a reasonable estimate of the Company's probable liability in connection with this matter. Export Controls Review In March 2018, the Company became aware of possible violations of U.S. export controls and economic sanctions laws and regulations involving the Company. The circumstances giving rise to these possible violations pertained to the Company’s collection of survey data from panelists within U.S. embargoed countries, as a part of the Company’s larger global survey efforts not intentionally targeted at such countries. The Company filed a joint initial notice of voluntary disclosure with the U.S. Department of the Treasury’s Office of Foreign Assets Control ("OFAC") and the U.S. Commerce Department’s Bureau of Industry and Security ("BIS") and commenced an internal review to identify the causes and scope of transactions that could constitute violations of the OFAC and BIS regulations. On May 31, 2018, the Company filed a final voluntary disclosure with OFAC and BIS. On September 10, 2018, the Company was notified that BIS did not find a violation of export regulations and closed the matter. If OFAC moves forward with this matter, the Company could be subject to fines or penalties. Although the ultimate outcome of this matter is unknown, the Company believes that a material loss was not probable or estimable as of June 30, 2019 . Other Matters In addition to the matters described above, the Company is, and may become, a party to a variety of legal proceedings from time to time that arise in the normal course of the Company's business. While the results of such legal proceedings cannot be predicted with certainty, management believes that, based on current knowledge, the final outcome of any such current pending matters will not have a material adverse effect on the Company's financial position, results of operations or cash flows. Regardless of the outcome, legal proceedings can have an adverse effect on the Company because of defense costs, diversion of management resources and other factors. Indemnification The Company has entered into indemnification agreements with each of the Company's directors and certain officers, and the Company's amended and restated certificate of incorporation requires it to indemnify each of its officers and directors, to the fullest extent permitted by Delaware law, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that he or she is or was a director or officer of the Company. The Company has paid and continues to pay legal counsel fees incurred by the present and former directors and officers who are involved in legal proceedings that require indemnification.

Restructuring and Related Activities [Abstract]
Organizational Restructuring	Organizational Restructuring In 2017, the Company implemented a reduction in force plan that resulted in the termination of approximately 10% of its workforce. That plan was complete as of December 31, 2018. In June and December 2018, the Company's Board of Directors authorized management to implement additional reductions in its workforce (less than 10% ) and rationalize its portfolio of leased properties due to the reductions in headcount ("2018 Restructuring Plans"). In connection with the 2018 Restructuring Plans, the Company expects to incur total exit-related costs of up to $13.0 million , including $10.3 million that was recorded in 2018. The remaining expense is expected to be recognized through the remainder of 2019 primarily as stock-based compensation. In May 2019, the Company implemented an additional reduction in force plan ("2019 Restructuring Plan") in order to reduce costs and more effectively align resources with business priorities. Together with attrition, the 2019 Restructuring Plan resulted in the termination of approximately 10% of the Company's workforce. In connection with the 2019 Restructuring Plan, the Company expects to incur total exit-related costs of up to $4.0 million , including $3.3 million that was recorded in the second quarter of 2019. The remaining expense is expected to be recognized during the third quarter of 2019. During the three and six months ended June 30, 2019 , the Company recognized approximately $2.9 million in restructuring costs. During the three and six months ended June 30, 2018 , the Company recognized restructuring costs of $3.8 million and $5.1 million , respectively. The total amount accrued for restructuring expenses as of June 30, 2019 is $4.0 million . The tables below summarize the balance of accrued restructuring expenses as of June 30, 2019 , which is recorded in accrued expenses in the Condensed Consolidated Balance Sheets, and the changes in the accrued amounts for the six months ended June 30, 2019 , by restructuring plan: 2018 Restructuring Plans (In thousands) Severance pay and benefits Short-term lease exit and other direct costs Long-term lease exit and other direct costs Total Accrued Balance as of December 31, 2018 $ 4,493 $ 708 $ 1,810 $ 7,011 Adoption of ASC 842 (1) — (708 ) (1,810 ) (2,518 ) Restructuring (2) (201 ) — — (201 ) Payments (2,098 ) — — (2,098 ) Accrued Balance as of June 30, 2019 $ 2,194 $ — $ — $ 2,194 (1) The Company adopted ASC 842, Leases, as of January 1, 2019.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned domestic and foreign subsidiaries. All intercompany transactions and balances are eliminated upon consolidation.
Reclassification	Reclassification Certain amounts in the prior year financial statements have been reclassified to conform to the current quarter presentation. Specifically, current deferred rent, accrued litigation settlements and current capital lease obligations have been aggregated within other current liabilities on the Condensed Consolidated Balance Sheets. Non-current capital lease obligations have been aggregated within other non-current liabilities on the Condensed Consolidated Balance Sheets.
Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements	Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and the measurement of: management's standalone selling price, principal versus agent revenue recognition, determination of performance obligations, determination of transaction price, including the determination of variable consideration and allocation of transaction price to performance obligations, deferred tax assets and liabilities, including the identification and quantification of income tax liabilities due to uncertain tax positions, the valuation and recoverability of goodwill and intangible assets, the determination of appropriate discount rates for lease accounting, the probability of exercising either lease renewal or termination clauses, the assessment of potential loss from contingencies, the valuation of assets and liabilities acquired in a business combination, the fair value determination of financing derivative liabilities and warrants, the allowance for doubtful accounts, and valuation of options, performance-based and market-based stock awards. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. The Company evaluates its estimates and assumptions on an ongoing basis.
Goodwill	Goodwill Goodwill is evaluated for impairment at least annually, as of October 1, by comparing the fair value of a reporting unit to its carrying value including goodwill recorded by the reporting unit. In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, Simplifying the Test for Goodwill Impairment , which eliminated the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, 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 and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the impairment loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The Company adopted the standard as of September 30, 2018. The Company has a single reporting unit. Accordingly, the impairment assessment for goodwill is performed at the enterprise level. Goodwill is reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company initially assesses qualitative factors to determine if it is necessary to perform the goodwill impairment review. Goodwill is reviewed for impairment if, based on an assessment of the qualitative factors, it is determined that it is more likely than not that the fair value of its reporting unit is less than its carrying value, or the Company decides to bypass the qualitative assessment. The carrying value of the reporting unit is reviewed utilizing a discounted cash flow model, and a market value approach is utilized to supplement the discounted cash flow model. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values. Additionally, the Company considers income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
Accounting for Warrants	Accounting for Warrants During the period ended June 30, 2019, the Company issued warrants that were determined to be freestanding financial instruments that qualify for liability treatment as a result of a net cash settlement feature associated with a cap on the issuance of shares under certain circumstances. Changes in the fair value of these instruments are immediately recorded in other (expense) income, net in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The fair value of the warrants is determined using a Monte Carlo simulation analysis within an option pricing model. The fair value estimate is determined using an estimate for the Company's credit rating, probability of change of control, dividend yield, risk-free rate, remaining term of the warrants and volatility. The fair values of the Company's warrants are estimated using forward projections of stock issuances with relative certainty and estimated cash payments at each exercise date discounted back to the valuation date with the remaining term of the related warrant. The primary sensitivity in the valuation of each warrant liability is driven by the Common Stock price at the measurement date and the observable volatility of the Common Stock.
Cost-Method Investments	Cost-Method Investment As of June 30, 2019 and December 31, 2018, the Company had one cost-method investment in common stock of an entity. The investment in equity securities is measured at fair value and is included in other non-current assets in the Condensed Consolidated Balance Sheets. Gains or losses related to the change in the fair value of the securities are recorded in other (expense) income, net within the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company sold its investment in equity securities in July 2019 for gross cash proceeds of $3.1 million . Because changes in the equity security’s fair value are reported in earnings as they occur, the sale of an equity security does not result in a gain or loss to earnings.
Loss Per Share	Loss Per Share Basic net loss per common share excludes dilution for potential Common Stock issuances and is computed by dividing net loss by the weighted-average number of shares of Common Stock outstanding for the period. 250,000 shares of Common Stock issuable upon the exercise of warrants held by Starboard ("penny warrants") were included in the number of outstanding shares used for the computation of basic net loss per share prior to the exercise of those warrants on April 3, 2019. In periods where the Company reports a net loss, the effect of anti-dilutive stock options, stock appreciation rights, restricted stock units, senior secured convertible notes and warrants are excluded and diluted net loss per share is equal to basic loss per share.
Leases	Leases The Company applies the provisions of Accounting Standards Codification ("ASC") 842, Leases . The Company's lease portfolio is comprised of three major classes. Real estate leases, which are the majority of the Company's leased assets, are accounted for as operating leases. Computer equipment and automobile leases, which comprise the remaining two major lease classes in the Company's portfolio, are generally accounted for as finance leases. The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Right-of-use ("ROU") assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. Operating ROU assets also include the impact of any lease incentives. For any leases in which an asset is not specifically identified, the Company performs a discrete analysis to identify whether there is an implicitly identified asset based on the contractual or other known requirements, such as the presence of substantive substitution rights on the part of the supplier or the right of the Company to sublease the asset. As part of this analysis, the Company also determines whether there are any restrictions on the use of the asset placed on the Company that are not considered protective rights on the part of the supplier and thus would allow the Company to assume which specific assets have been identified. The Company identifies separate lease and non-lease components within the contract. Non-lease components primarily include payments for common-area maintenance and management charges. The Company has elected to combine lease and non-lease payments and account for them together as a single lease component, which increases the amount of the Company's ROU assets and lease liabilities. The interest rate used to determine the present value of the future lease payments is the Company's incremental borrowing rate, because the interest rate implicit in the Company's leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The Company's current discount rates range from 12% to 15% depending on the term of the arrangement. The Company's lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company considers contractual-based factors such as the nature and terms of the renewal or termination, asset-based factors such as physical location of the asset and entity-based factors such as the importance of the leased asset to the Company's operations to determine the lease term. The Company generally uses the base, non-cancelable, lease term when determining the ROU assets and lease liabilities. Payments under the Company's lease arrangements are primarily fixed; however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the measurement of ROU assets and lease liabilities. These amounts include payments affected by changes in the Consumer Price Index and payments for common-area maintenance, real estate taxes and utilities, which are based on usage or performance. Operating leases are included in operating ROU assets, current operating lease liability, and non-current operating lease liability in the Condensed Consolidated Balance Sheets. The Company recognizes lease expense for its operating leases on a straight-line basis over the term of the lease. Finance lease activity is included in property and equipment, net; current finance lease liabilities are aggregated into other current liabilities; and non-current finance lease obligations are aggregated in other non-current liabilities in the Company's Condensed Consolidated Balance Sheets. Finance ROU assets are amortized on a straight-line basis over their estimated useful lives. Income from subleased properties is recognized on a straight-line basis and presented as a reduction of general and administrative expense in the Company's Condensed Consolidated Statement of Operations. In addition to sublease rent, variable non-lease costs such as common-area maintenance and utilities are charged to subtenants over the duration of the lease for their proportionate share of these costs. These variable non-lease income receipts are recognized in operating expenses as a reduction to costs incurred by the Company in relation to the head lease.
Change in Accounting Policy, Accounting Standards Recently Adopted and Recently Issued Accounting Pronouncements	Change in Accounting Policy The Company adopted ASC 842, with a date of initial application of January 1, 2019, using the modified retrospective transition method with optional transition relief, under which the Company did not restate prior comparative periods and instead recorded an adjustment to stockholders' equity as of the date of initial implementation for the cumulative impact of adoption. As part of the transition, the Company implemented new internal controls and key system functionality to enable the preparation of financial information on adoption, and elected the following practical expedients: • Not to reassess whether any expired or existing contracts are or contain leases. • Not to reassess the lease classification for any expired or existing leases. • Not to reassess initial direct costs for any existing leases. • The hindsight practical expedient in determining the lease term. • The practical expedient whereby the lease and non-lease components will not be separated for all classes of assets. • Not to record ROU assets and corresponding lease liabilities with a lease term of 12 months or less. The Company has elected to net its sublease exit liabilities recognized under ASC 420, Exit or Disposal Cost Obligations as an adjustment to the opening ROU asset for the corresponding head lease established upon the adoption of ASC 842. Sublease exit liabilities had a carrying value of $2.5 million as of December 31, 2018. Accounting Standards Recently Adopted In July 2017, the FASB issued ASU 2017-11, Earnings Per Share, Distinguishing Liabilities from Equity; Derivatives and Hedging . This update was issued to address complexities in accounting for certain equity-linked financial instruments containing down round features. The amendments in ASU 2017-11 change the classification analysis of these financial instruments (or embedded features) so that equity classification is no longer precluded. The amendments in ASU 2017-11 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This update was issued to allow companies to reclassify tax effects stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. Companies that elect to reclassify these amounts must reclassify stranded tax effects for all items accounted for in accumulated other comprehensive income. The amendments in ASU 2018-02 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Early adoption is permitted. Upon adoption of the standard, the Company did not elect to reclassify stranded tax effects to retained earnings. The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting. This update was issued to allow companies to account for share-based payment transactions with non-employees in the same way as share-based payment transactions with employees, with the main differences being the accounting for attribution and a contractual term election for valuing non-employee equity share options. The amendments in ASU 2018-07 are effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those annual reporting periods. Per ASU 2018-07, this update should be applied on a modified retrospective basis via a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Early adoption is permitted only if the Company has adopted ASC 606, Revenue from Contracts with Customers . The adoption of the standard did not have an impact on the Condensed Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2019, including interim reporting periods within those annual periods. Early adoption is permitted. The Company early adopted this standard, effective January 1, 2019, on a prospective basis. The adoption did not have an impact on the Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)
Fair Value Measurements	The fair values of the Company's financing derivatives are estimated using forward projections and are discounted back at rates commensurate with the remaining term of the related derivative. The primary sensitivity in the interest rate reset derivative liability is driven by the Common Stock price at the measurement date, the observable volatility of the Common Stock, and the discount
