Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 ("CEO") and director and Sarah Hofstetter resigned as the Company's President, effective immediately. On the same day, the Company appointed Dale Fuller as Interim CEO, and Mr. Fuller assumed the role of CODM. On November 4, 2019, Mr. Fuller resigned as Interim CEO and William Livek was appointed as CEO and Executive Vice Chairman, and Mr. Livek 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 and capital expenditures of its business. 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, as described in Footnote 4, Long-Term Debt. For additional information related to the restructuring plans, refer to Footnote 16, Organizational Restructuring.

The Company has secured the following long-term financing in order to increase its available working capital and fund ongoing operations:

•

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. For additional information, refer to Footnote 4, Long-term Debt.

•

On June 26, 2019, 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. On October 14, 2019, the Company issued 2,728,513 shares of Common Stock to CVI upon exercise by CVI of the Series C warrant. For additional information, refer to Footnote 5, Stockholders' Equity.

•

On December 31, 2019, the Company's wholly owned subsidiary, Rentrak B.V., entered into an agreement with several third parties (collectively the "Noteholder") for a secured term note (the "Secured Term Note") in exchange for gross proceeds $13.0 million. The Secured Term Note matures on December 31, 2021, is cash collateralized, and has an annual interest rate of 9.75% that is payable monthly in arrears. For additional information, refer to Footnote 4, Long-term Debt.

As of December 31, 2019, the Company was in compliance with its covenants under the senior secured convertible notes and the Secured Term Note.

Liquidity could be negatively affected by a decrease in demand for the Company's products and services or additional losses from operations, as well as payment of expenses incurred in prior periods. Liquidity could also be negatively affected if the Company elects to pay its interest liability on the senior secured convertible notes (currently set at 12.0% per year) in cash in lieu of Common Stock. Finally, liquidity could be significantly affected if the Company is unable to maintain compliance with the affirmative and negative covenants in the senior secured convertible notes and the Secured Term Note, including the minimum cash balance requirements.

The Company continues to be focused on maintaining flexibility in terms of sources, amounts, and the timing of any potential financing, refinancing or strategic transaction, in order to best position the Company for future success. The Company believes that its sources of funding, after taking into account the restructuring and financing transactions described above, as well as the availability of the rights offering described in Footnote 4, Long-term Debt, will be sufficient to satisfy the Company's estimated liquidity needs and allow the Company to remain in compliance with its covenants under the senior secured convertible notes and the Secured Term Note for at least one year after the date that these financial statements are issued. However, the Company cannot

predict with certainty the outcome of its actions to generate liquidity, including the availability of additional financing, or whether such actions would generate the expected liquidity as currently planned.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying 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 year presentation. Specifically, current capital lease obligations have been aggregated within other current liabilities on the Consolidated Balance Sheets. Non-current capital lease obligations have been aggregated within other non-current liabilities on the Consolidated Balance Sheets.

Use of Estimates and Judgments in the Preparation of the Consolidated Financial Statements

The preparation of financial statements in conformity with generally accepted accounting principles ("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 ("SSP"), 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 fair value determination of financing-related liabilities and warrants, the allowance for doubtful accounts, and the 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.

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company applies the three-tier GAAP value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1 - observable inputs such as quoted prices in active markets;

Level 2 - inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 - unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure. The Company's assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

For assets that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability.

Assets and liabilities that are measured at fair value on a non-recurring basis include property and equipment, operating right-of-use assets, intangible assets and goodwill. The Company recognizes these items at fair value when they are considered to be impaired or upon initial recognition. The fair value of these assets and liabilities are determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models.

Fair Value of Financial Instruments

Due to their short-term nature, the carrying amounts reported in the Company's Consolidated Financial Statements approximate the fair value for cash and cash equivalents, restricted cash including certificates of deposit, accounts receivable, accounts payable

and accrued expenses, the current portion of contract liability and customer advances. The carrying values of finance lease obligations approximate their fair value as the interest rates for the lease term approximate market rates (Level 2).

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 derivatives. The fair value of the interest reset liability is determined based on an estimate for the Company's credit rating, the premium attributable to the payment-in-kind feature of the senior secured convertible notes ("Notes"), and premium estimates for company-specific risk factors (together, the credit adjusted discount rate), the Company's Common Stock price at measurement date, the observable volatility of the Common Stock and risk-free rate. The fair value of the change in control redemption derivative liabilities is determined based on the probability of change of control, credit adjusted discount rate, and risk-free rate. The fair value of the Notes is determined using the credit adjusted discount rate, the Company's Common Stock price at the valuation date, risk-free rate and volatility commensurate with the remaining term of the Notes.

Cash and Cash Equivalents

The Company considers highly liquid investments with an original maturity of three months or less at the time of purchase and qualifying money-market funds as cash equivalents. Cash and cash equivalents are maintained with several financial institutions domestically and internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation ("FDIC") insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary.

Restricted Cash

Restricted cash represents the Company's cash collateral requirements under the Secured Term Note, outstanding letters of credit, international payroll processing exposures, and corporate credit card obligations. As of December 31, 2019 and 2018, the Company had $20.2 million and $6.1 million of restricted cash, respectively, of which $1.0 million was held in certificates of deposit as of both December 31, 2019 and 2018. As of December 31, 2019, certificates of deposit in the amount of $0.9 million will mature within the next one year.

Allowance for Doubtful Accounts

The Company generally grants uncollateralized credit terms to its customers and maintains an allowance for doubtful accounts to reserve for uncollectible receivables. Allowances are based on management's judgment, which considers historical collection experience, a specific review of all significant outstanding receivables, an assessment of company-specific credit conditions and general economic conditions.

The following is a summary of the allowance for doubtful accounts:

Property and Equipment, net

Property and equipment is recorded at cost, net of accumulated depreciation, and is depreciated on a straight-line basis over the estimated useful lives of the assets, ranging from 3 to 5 years. Assets under finance leases are recorded at their net present value at the commencement of the lease. Assets under finance leases and leasehold improvements are amortized over the shorter of the related lease terms or their useful lives. Replacements and major improvements are capitalized; maintenance and repairs are expensed as incurred.

Capitalized Software

Capitalized software, which is included in property and equipment, net, consists of costs to purchase and develop internal-use software, which the Company uses to provide services to its clients. The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended, until the time the software is placed in service for its intended use. Any costs incurred during

subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for use in the Company's products, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is typically assessed to be 3 to 5 years. During the years ended December 31, 2019 and 2018 the Company capitalized $11.9 million and $9.6 million in internal-use software costs, respectively. The Company depreciated $4.8 million and $1.3 million in capitalized internal-use software costs during the years ended December 31, 2019 and 2018, respectively. No amounts were capitalized in 2017.

Certain costs incurred for implementation, setup, and other upfront activities in a hosting arrangement that is a service contract are capitalized within other non-current assets in the Consolidated Balance Sheets. Once the implementation has been completed, the capitalized amounts are amortized on a straight-line basis over the remaining noncancelable term of the hosting arrangement, including options to extend the hosting arrangement when it is reasonably certain the options will be exercised. The Company capitalized $1.0 million of implementation costs in 2019. No expenses were recognized in 2019, 2018 or 2017.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed when a business is acquired. The valuation of intangible assets and goodwill involves the use of management's estimates and assumptions and can have a significant impact on future operating results. The Company initially records its intangible assets at fair value. Intangible assets with finite lives are amortized over their estimated useful lives while goodwill is not amortized but 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.

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 the 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 combination of the discounted cash flow model and a market value approach. 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, general industry, and market and macro-economic conditions. 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 a non-cash impairment charge.

The Company performed an interim analysis as of June 30, 2019 and determined that goodwill was then impaired. Refer to Footnote 9, Goodwill and Intangible Assets for further information. The Company completed its annual assessment on October 1, 2019, and there was no additional impairment of goodwill at the assessment date. There were no goodwill impairment charges recognized during the years ended December 31, 2018 and 2017.

Intangible assets with finite lives are generally amortized using the straight-line method over the following useful lives:



	Useful Lives (Years)
Acquired methodologies/technology	2 to 7
Acquired software	3
Customer relationships	3 to 7
Intellectual property	2 to 13
Panel	1 to 7
Trade Names	2 to 6
Other	6 to 8

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.

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. 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 strategic alliance (the "strategic alliance") with WPP plc and its affiliates ("WPP") was impaired. Refer to Footnote 9, Goodwill and Intangible Assets for further information. There were no impairment charges recognized during the years ended December 31, 2018 and 2017 or subsequent to June 30, 2019.

Accounting for Warrants

In June 2019, the Company issued warrants to CVI in connection with the private placement described above. The warrants 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 income (expense), net in the 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 cost of debt, probability of change of control, dividend yield, risk-free rate, remaining term of the warrants and volatility. The fair values of the warrants are estimated using forward projections of stock issuances with relative certainty and estimated payments at each exercise date discounted back to the valuation date with the remaining term of the related warrants. 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.

Equity Securities

The Company sold its remaining investment in equity securities during 2019 for gross cash proceeds of $3.8 million. Changes in the investment's fair value were reported in other income (expense), net as they occurred; therefore, the sale of this investment did not result in a gain or loss in the Consolidated Statements of Operations and Comprehensive Loss.

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 13.6% to 14.6% depending on the term of the lease.

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 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 Consolidated Balance Sheets. Finance ROU assets are amortized on a straight-line basis over their estimated useful lives.

The execution of a sublease where remaining lease payments on the head lease exceed the anticipated sublease receipts reflects an indication of impairment which suggests the carrying value of the ROU asset may not be recoverable. The Company treats operating lease ROU assets as financing transactions, thereby excluding the operating lease liability and related lease payments from the head lease, for purposes of testing recoverability. The Company compares the estimated undiscounted cash flows generated by the sublease to the current carrying value of the ROU asset. If the undiscounted cash flows are less than the carrying value of the ROU asset, the Company records an impairment loss equal to the excess of the ROU asset's carrying value over its fair value consistent with other long-lived assets.

Income from subleased properties is recognized on a straight-line basis and presented as a reduction of costs, allocated among operating expense line items, in the Company's Consolidated Statements of Operations and Comprehensive Loss. 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 Consolidated Balance Sheets until the end of the lease term.

Change in Accounting Policy

The Company adopted ASC 842, with an initial application date 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 Consolidated Balance Sheets but did not have an impact on the Consolidated Statements of Operations and Comprehensive Loss. 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

Foreign Currency

Generally, the functional currency of the Company's foreign subsidiaries is the local currency. In those cases where the transaction is not denominated in the functional currency, the Company revalues the transaction to the functional currency and records the translation gain or loss in the Company's Statements of Operations and Comprehensive Loss. Assets and liabilities are translated at the current exchange rate as of the end of the year, and revenues and expenses are translated at average exchange rates in effect during the year. The gain or loss resulting from the process of translating a foreign subsidiary's functional currency financial statements into U.S. Dollars ("USD") is reflected as foreign currency cumulative translation adjustment and reported as a component of accumulated other comprehensive loss. The translation adjustment for intercompany foreign currency loans that are permanent in nature are also recorded as accumulated other comprehensive loss. Translation adjustments on intercompany accounts that are short term in nature are recorded as gain (loss) from foreign currency transactions. For foreign entities where USD is the functional currency, re-measurement of gains and losses related to deferred tax assets and liabilities are reflected in income tax provision in the Company's Statements of Operations and Comprehensive Loss.

Revenue Recognition

The Company applies the provisions of ASC 606, Revenue from Contracts with Customers, and all related applicable guidance. The Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company's contracts with customers may include multiple promised goods and services. Contracts with multiple performance obligations typically consist of a mix of subscriptions to the Company's online database, customized data services, and delivery of periodic custom reports based on information obtained from the database. In such cases, the Company identifies performance obligations by evaluating whether the promised goods and services are capable of being distinct and distinct within the context of the contract at contract inception. Promised goods and services that are not distinct at contract inception are combined as one performance obligation. Once the Company identifies the performance obligations, the Company will determine the transaction price based on contractually fixed amounts and an estimate of variable consideration. The Company allocates the transaction price to each performance obligation based on relative standalone selling price ("SSP"). Judgment is exercised to determine the SSP of each distinct performance obligation. The Company will constrain estimates of variable consideration based on its expectation of recovery from the customer. Some sources of variable consideration such as refunds, penalties, or allowances will reduce transaction price. In some instances, the Company may have non-cash consideration or elements of consideration payable to the customer, which will also be included in the transaction price. These sources of variable consideration are relatively infrequent and generally not significant. The Company recognizes revenue when (or as) it satisfies a performance obligation by transferring promised goods or services to a customer. Customers may obtain the control of promised goods or services over time or at a point in time. The Company recognizes revenue net of sales taxes remitted to government authorities. In general, transaction price is determined by estimating the fixed amount of consideration to which the Company is entitled for transfer of goods and services and all relevant

sources and components of variable consideration. Variable consideration is estimated based on the most likely amount or expected value approach, depending on which method the Company expects to better predict the amount of consideration to which it will be entitled. Once the Company elects one of the methods to estimate variable consideration for a particular type of performance obligation, the Company will apply that method consistently.

Subscription-based revenues are typically recognized on a straight-line basis over the access period, which ranges from three to thirty-six months. Revenue for validated Campaign Essentials ("vCE") and Comscore Campaign Ratings ("CCR") is recognized over time, either on a time-elapsed basis, as the Company is providing services that the customer is continuously consuming and receiving benefit from, or on an output method, such as volume of impressions processed. Activation products vary in nature, and can be recognized over time, generally on an input method time-elapsed basis, as the Company provides continuous tracking of activity. Other activation products are delivered at a point in time, based on custom attributes agreed upon by customers and the Company.

The Company's customized data services are delivered in the form of custom recurring reports or ad hoc reports. Custom report performance obligations, in general, are transferred at a point in time once the product has been delivered to the customer.

Survey products vary in nature and can be recognized at a point in time, generally on an output method report delivery basis, once the final report has been delivered to the customer. Other survey products are recognized over time, generally on a time-elapsed basis, as the Company provides access to continuous reporting on survey results through a user interface. Survey services consist of survey design with subsequent data collection, analysis and reporting.

For performance obligations satisfied at a point in time, the Company evaluates a number of factors to determine whether control of goods and services has been transferred. The Company considers whether there is a present right to payment and whether the customer has accepted the asset. In many instances the Company has objective evidence of the acceptance criteria, while in other cases the acceptance provisions are substantive, and the customer must affirmatively signal acceptance. The preceding two factors are not the only factors that may be considered. Other considerations include, but are not limited to, whether risks and rewards of ownership have been transferred for a particular product.

For the majority of its products and services, the Company applies an adjusted market assessment approach for the determination of SSP for identified performance obligations. In general, the Company bundles multiple products and very few are sold on a standalone basis. The Company uses rate cards and pricing calculators that are periodically reviewed and updated to reflect the latest sales data and observable inputs by industry, channel, geography, customer size, and other relevant groupings. Certain products are sold on a standalone basis in a narrow band of prices. If a product is sold outside of the narrow band of prices, it will be assigned the midpoint of the narrow band for purposes of allocating transaction price on a relative SSP basis.

Customers may have the right to cancel their contracts by providing a written notice of cancellation, although most subscription-based contracts are non-cancelable. If a customer cancels its contract, the customer is generally not entitled to a refund for prior services. In the event a portion of a contract is refundable, revenue recognition is delayed until the refund provision lapses. For multi-year contracts with annual price increases and no opt out clauses, the total consideration for each of the years included in the contract term will be combined and recognized on a straight-line basis over the term of the contract.

The Company may enter into multiple contracts with a single counterparty at or near the same time. The Company will combine contracts and account for them as a single contract when one or more of the following criteria are met: (i) the contracts are negotiated as a package with a single commercial objective, (ii) consideration to be paid in one contract depends on the price or performance of the other contract, and (iii) goods or services promised are a single performance obligation.

For transactions that involve third parties, the Company evaluates whether the Company is the principal, in which case the Company recognizes revenue on a gross basis. If the Company is an agent, the Company recognizes revenue on a net basis. In certain countries, the Company may use third-party resellers to sell its products and services. In these transactions, the Company is generally the principal as the Company controls the products and services and is primarily responsible for providing them to the end user. The Company also has certain revenue share arrangements that involve the use of partner data in its sales to end users or the use of its data in partner sales to end users. In these arrangements, the Company assesses which party controls the specified goods or services before they are transferred to the customer, as well as other indicators such as the party primarily responsible for fulfillment, inventory risk, and discretion in establishing price.

The Company enters into a limited number of monetary contracts with multichannel video programming distributors ("MVPDs") that involve both the purchase and sale of services with a single counterparty. The Company assesses each contract to determine if the revenue and expense should be presented gross or net. The Company recognizes revenue for these contracts to the extent that SSP is established for distinct services provided. Any excess consideration above the established SSP of services is presented as an offset to cost of revenues in the Consolidated Statements of Operations and Comprehensive Loss.

Nonmonetary transactions represent data exchanges, which may consist of digital usage and general demographic data. The data obtained through nonmonetary transactions differs from the data provided by the Company in the exchange. Under ASC 606, the transaction price of a nonmonetary exchange that has commercial substance is based on the fair value of the non-cash consideration

received. If an entity cannot reasonably estimate the fair value of the non-cash consideration received, then it uses the estimated selling price of the promised goods or services. None of the nonmonetary transactions entered into by the Company met the requirements to recognize revenue or expense. Therefore, these nonmonetary transactions are not reflected in the Consolidated Financial Statements.

Contract Balances

Accounts receivable are billed and unbilled amounts related to the Company's rights to consideration as performance obligations are satisfied when the rights to payment become unconditional but for the passage of time.

Contract assets are included in prepaid expenses and other current assets within the Consolidated Balance Sheets. Contract assets represent the Company's right to consideration in exchange for goods or services transferred to the customer either prior to the receipt of consideration or before payment is due.

Contract payments are generally due in advance for subscription-based services or prior to delivery of custom reports. If a contract exists under ASC 606, advance payments are recorded as a contract liability or a customer advance until the performance obligations are satisfied and revenue is earned.

Contract liabilities relate to amounts billed in advance, or advance consideration received from customers, for which transfer of control of the good or service occurs at a later point in time. Customer advances relate to amounts billed in advance, or advance considerations received from customers, for contracts with termination rights for which transfer of control of the good or service occurs at a later point in time. Contract liabilities and customer advances to be recognized in the succeeding twelve-month period are classified as current and the remaining amounts are classified as non-current liabilities within the Consolidated Balance Sheets.

Transaction Price Allocated to the Remaining Performance Obligations

The Company elected an optional exemption to not disclose information about remaining performance obligations that have an original expected duration of one year or less, or where the transaction price allocated to unsatisfied performance obligations for which variable consideration is allocated entirely to a wholly unsatisfied performance obligation, or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation in accordance with the series guidance.

Costs to Obtain or Fulfill a Contract

The Company elected the practical expedient to recognize the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets is one year or less. These costs include commission programs to compensate employees for obtaining new contracts and are included in selling and marketing expense.

Certain costs to fulfill are capitalized in relation to long-term contracts wherein the transfer of goods and services will occur at a point in time. In addition, the Company capitalizes costs to fulfill for long-term contracts that are incurred during a setup period prior to transferring control of the good or service over time. These costs include dedicated employees, subcontractors, and other third-party costs. The Company will assess capitalized costs to fulfill at each reporting period for recoverability. These costs are included in cost of revenue and are recognized in the same manner as the corresponding performance obligation.

Cost of Revenues

Cost of revenues consists primarily of costs to produce the Company's products including viewing data from MVPDs, census-based, panel and other third-party data as well as costs to operate its network infrastructure including data center, data storage and compliance costs. Other costs include amortization of capitalized fulfillment costs, employee costs including stock-based compensation, depreciation related to assets used to maintain the network and produce products and allocated overhead, including rent and depreciation expenses generated by general purpose equipment and software.

Selling and Marketing

Selling and marketing expenses consist primarily of salaries, commissions, stock-based compensation, benefits and bonuses for personnel associated with sales and marketing activities, as well as costs related to online and offline advertising, product management, seminars, promotional materials, public relations, other sales and marketing programs, and allocated overhead, including rent and other facilities related costs, and depreciation.

Research and Development

Research and development expenses consist primarily of salaries, stock-based compensation, benefits and related costs for personnel associated with research and development activities, as well as allocated overhead, including rent and other facilities related costs, and depreciation.

General and Administrative

General and administrative expenses consist primarily of salaries, stock-based compensation, benefits and related costs for executive management, finance, accounting, human capital, legal, information technology and other administrative functions, as well as professional fees and allocated overhead, including rent and other facilities related costs, depreciation and expenses incurred for other general corporate purposes.

Investigation and Audit Related

Investigation expenses are professional fees associated with legal and forensic accounting services rendered as a result of an internal Audit Committee investigation into matters related to the Company's revenue recognition practices, disclosures, internal controls, corporate culture and employment practices prior to 2017. Audit related expenses consist of professional fees associated with accounting related consulting services and external auditor fees associated with the audit of the Company's prior-year financial statements. Also included are litigation related expenses, which include legal fees associated with various lawsuits or investigations that were initiated either directly or indirectly as a result of the Audit Committee's investigation.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash and accounts receivable. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. With respect to accounts receivable, credit risk is mitigated by the Company's ongoing credit evaluation of its customers' financial condition.

Debt Issuance Costs

The Company reflects debt issuance costs in the Consolidated Balance Sheets as a direct deduction from the gross amount of debt, consistent with the presentation of a debt discount. Debt issuance costs are amortized to interest expense, net over the term of the underlying debt instrument, utilizing the effective interest method.

Derivative Financial Instruments

The Company has derivative financial instruments that are not hedges and do not qualify for hedge accounting. Changes in the fair value of these instruments are recorded in other income (expense), net in the Consolidated Statements of Operations and Comprehensive Loss.

Stock-Based Compensation

The Company estimates the fair value of stock-based awards on the date of grant. The fair value of stock options with only service conditions is determined using the Black-Scholes option pricing model. The fair value of restricted stock units ("RSUs") and restricted stock awards is based on the closing price of the Company's Common Stock on the date of grant. The Company amortizes the fair value of awards expected to vest on a straight-line basis over the requisite service periods of the awards, which is generally the period from the grant date to the end of the vesting period. The determination of the fair value of the Company's stock option awards is based on a variety of factors, including, but not limited to, the Company's Common Stock price, risk-free rate, expected stock price volatility over the expected life of awards, dividend yield and actual and projected exercise behavior. Additionally, the

Company has estimated forfeitures for stock-based awards at the dates of grant based on historical experience and adjusted for future expectation. The Company performs a review of the forfeiture rate assumption at least annually or as deemed necessary if there are changes that could potentially significantly impact the future rate of forfeiture of its stock-based awards. The forfeiture estimate is revised as necessary if actual forfeitures differ from these estimates.

The Company issues RSU awards with restrictions that lapse upon the passage of time (service vesting), achieving performance targets, fulfillment of market conditions or a combination thereof. For those RSU awards with only service vesting, the Company recognizes compensation cost on a straight-line basis over the service period. For awards with performance conditions only, or performance and service conditions, the Company starts recognizing compensation cost over the remaining service period when it is probable the performance conditions will be met. Stock awards that contain performance vesting conditions are excluded from diluted earnings per share computations until the contingency is met as of the end of that reporting period.

For awards with market conditions, the Company recognizes compensation cost over the remaining service period, with the effect of the market condition reflected in the calculation of the award's fair value at grant date. The Company values awards with market conditions using certain valuation techniques, such as a Monte Carlo simulation analysis. The Company determines the requisite service period based on the longer of the explicit service period and the derived service period. Stock awards that contain market vesting conditions are included in the computations of diluted EPS reflecting the number of shares that would be issued based on the current market price at the end of the period being reported on, if their effect is dilutive.

Under the Company's annual incentive compensation plan, the Company may grant immediate or future vesting RSUs to certain employees. For these awards, stock-based compensation expense is recognized over the requisite service period, which generally precedes the grant date. The Company accrues stock-based compensation expense for these awards until the date of grant.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The Company determines the realizability of its deferred tax assets primarily based on the reversal of existing taxable temporary differences and projections of future taxable income (exclusive of reversing temporary differences and carryforwards). In evaluating such projections, the Company considers its history of profitability, the competitive environment, and general economic conditions. In addition, the Company considers the time frame over which it would take to utilize the deferred tax assets prior to their expiration.

For certain tax positions, the Company uses a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company's policy is to recognize interest and penalties related to income tax matters in income tax expense.

On December 22, 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the "TCJA") was signed into law. As of December 31, 2018, the Company's accounting for the TCJA has been completed. The Company has determined the effects of certain provisions, including but not limited to: a reduction in the corporate tax rate from 35% to 21%, a limitation of the deductibility of certain officers' compensation, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation of net operating losses generated after 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse or "BEAT") on excessive amounts paid to foreign related parties, and a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (global intangible low-taxed income or "GILTI"). As part of its GILTI review, the Company has determined that it will account for GILTI income as it is generated (i.e., treat it as a period expense). Given the Company's loss position in the U.S. and the valuation allowance recorded against its U.S. net deferred tax assets, these provisions have not had a material impact on the Company's financial statements.

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 ("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 with a reported 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 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:



	Years Ended December 31,
	2019	2018	2017
Stock options, stock appreciation rights, restricted stock units, senior secured convertible notes and warrants	12,443,032	8,392,748	2,837,872

Comprehensive Loss

Comprehensive loss consists of net loss, foreign currency translation adjustments and the unrealized gains on investments in marketable securities.

Accounting Standards Recently Adopted

In July 2017, the Financial Accounting Standards Board ("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 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 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 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 Consolidated Financial Statements.

In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections. This update was issued to align the codification requirements with the issuance of SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231

and 33-10442, Investment Company Reporting Modernization, as well as other miscellaneous updates, including updates to XBRL taxonomy. The adoption did not have an impact on the Consolidated Financial Statements.

Recently Issued Accounting Pronouncements

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes by eliminating certain exemptions as well as a few other changes. The amendments are effective for fiscal years beginning after December 15, 2020, 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 in the process of evaluating the guidance but does not believe that the adoption of this standard will have a material impact on the Consolidated Financial Statements or related disclosures.

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 in the process of evaluating the guidance but does not believe that the adoption of this standard will have a material impact on the Consolidated Financial Statements or related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model which requires consideration of forward-looking information to calculate credit loss estimates. These changes will result in an earlier recognition of credit losses. The amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company's financial assets held at amortized cost include certificates of deposit, accounts receivable and contract assets. The Company will adopt the new standard effective January 1, 2020 and does not expect the adoption of this standard will have a material impact on the Consolidated Financial Statements or related disclosures.

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 per share.

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. On January 30, 2019, the interest rate reset to 12.0% 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 remains at 12.0% based on the January 30, 2020 reset calculation. 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 utilized a "with-and-without" convertible bond model, modified to incorporate the interest rate reset feature, using the following key assumptions:


•	Credit Adjusted Discount Rate: The Company estimated a market-based discount rate of 25%.


•	Stock Price: The stock price was measured using 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.


•	Volatility: Based on the historical volatility of the Company's Common Stock, determined to be 41.3% as of the valuation date.


•	Term: Based on the time period of the Notes maturity, 4 years.


•	Risk Free Rate: Assumed to be 2.2% based on the Federal Reserve bond yield.

Based upon the modified convertible bond model utilized by management, the fair value of the interest rate reset feature was determined to be $6.4 million as of January 16, 2018 and was recognized as an issuance discount for the Initial Notes at inception.

Interest on the Initial Notes is payable on a quarterly basis in arrears beginning on 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 (the "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, July 1, 2019 and October 1, 2019, the Company paid its quarterly accrued interest liability on the Notes for the first, second and third quarters through the issuance of 243,261, 856,289 and 2,957,579 PIK Interest Shares, respectively. The Company paid accrued interest of $6.1 million on January 2, 2020 in cash. The accrued interest was classified within accrued expenses in the Consolidated Financial Statements as of December 31, 2019.

Management evaluated the Notes Option and determined that it met the definition of a derivative as it represented a written option. The Notes Option qualified for liability treatment and was initially measured at fair value, with subsequent changes in fair value being recorded in earnings. To determine the fair value of the Notes Option, management utilized an option pricing model as the option represents a put option that gains value as the underlying asset (Common Stock) decreases in value. The following key assumptions were utilized in the Company's estimate of the fair value of the Notes Option derivative:


•	Stock Price: The stock price was measured using 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.


•	Volatility: Based on the historical volatility of the Company's Common Stock, determined to be 38.4% as of the valuation date.


•	Term: Based on the time period of the Notes Option, 6 months.


•	Risk Free Rate: Assumed to be 1.6% based on the Federal Reserve bond yield with a term commensurate with the remaining life of the Notes Option.

Based upon the option pricing model utilized, management estimated the fair value of the Notes Option as of January 16, 2018 to be $2.1 million. The fair value was recognized as an issuance discount for the Initial Notes at inception.

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 (the "make-whole change of control redemption"). Management evaluated this make-whole 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 make-whole change of control derivative is treated as a liability, initially measured at fair value with subsequent changes in fair value recorded in earnings. Management utilized a probability-adjusted binomial lattice model to determine the fair value of the make-whole change of control derivative, with the following key assumptions:


•	Probability: The Company utilized a range between 0% and 10% to estimate the likelihood of occurrence.


•	Term: Based on the time period of the feature, 4 years.


•	Risk Free Rate: Assumed to be 2.2% based on the U.S. Treasury bonds on the valuation date with a term commensurate with the remaining life of the change of control derivative.

Based on the binomial lattice model, the Company determined the fair value of the make-whole redemption provision as of January 16, 2018 to be $4.4 million. The fair value was recognized as an issuance discount of the Initial Notes at inception. See "Notes Modifications" below.

The Notes 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 (currently $40.0 million), and (v) the timely filing of certain disclosures with the SEC. The Company is in compliance with its debt covenants as of December 31, 2019.

In connection with the issuance of the Initial Notes, the Company also agreed to issue to 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 exercisable for five years from the date of issuance. The Company valued the warrants using the Black-Scholes model, with the following key assumptions:


•	Stock Price: The stock price was measured using fair value of the Common Stock on the closing date of the Initial Notes issuance, January 16, 2018, which was $24.45 per share.


•	Volatility: The Company determined volatility to be 39.6% based on the historical volatility of its Common Stock daily volume weighted average price with a look-back period commensurate with the term of the warrants.


•	Risk Free Rate: Assumed to be 2.4% based on U.S. Treasury bonds on the valuation date with a 5-year term.


•	Dividend Yield: Assumed to be zero based on the historical payout history of the Company.

Based on the Black-Scholes model, the Company determined that the fair value of the warrants as of January 16, 2018 was $6.1 million. The Company recorded the warrants at allocated proceeds of $5.7 million, less allocated issuance costs of $0.2 million, as additional paid-in capital.

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.

On August 8, 2018, the Company and Starboard entered into an amendment to the outstanding Notes to reduce the requirement to maintain certain minimum cash balances. In connection with and as consideration for this modification, the Company issued to Starboard $2.0 million in additional aggregate principal amount of senior secured convertible notes, $1.5 million of which was classified as additional Initial Notes. The terms of the additional notes are identical to the terms of the Initial Notes, except with regard to the date from which interest began to accrue thereon, which is August 8, 2018. The amendment is 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 Initial Notes on the modification date and will be amortized to interest expense over the remaining term of the modified debt. In connection with the modification of the Notes, the Company recorded $0.2 million in additional derivative liabilities.

On November 13, 2018, the Company and Starboard entered into an agreement whereby the applicable period for the $20.0 million minimum cash balance required to be maintained by the Company was extended until the earlier of August 9, 2019 or the date the Company filed its Form 10-Q for the quarterly period ended June 30, 2019, subject to certain limitations. The 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. In connection with, and as consideration for these amendments, the Company issued to Starboard $2.0 million in additional aggregate principal amount of senior secured convertible notes, the terms of which are identical to the terms of the Initial Notes, except with regard to the date from which interest began to accrue thereon, which is November 13, 2018. In connection with this modification, the Company recorded $0.2 million in additional derivative liabilities.

Additional modifications to the Initial Notes are described under "Notes Modifications" below.

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 thereon, which was May 17, 2018. Upon the exercise of the Notes Option, the derivative liability recorded for the Notes Option at inception was settled. Management determined the fair value of the Notes Option immediately prior to settlement utilizing 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 closing date of the Option Notes issuance, May 17, 2018, which was $21.75 per share.


•	Volatility: Based on the historical volatility of the Company's Common Stock, determined to be 26.3% as of the valuation date.


•	Term: Based on the time period of the expected exercise of the Notes Option, 0.16 years.


•	Risk Free Rate: Assumed to be 1.8% based on the Federal Reserve bond yield with a term commensurate with the remaining life of the Notes Option.

Based upon the option pricing model utilized, management estimated the fair value of the Notes Option as of May 17, 2018 to be $5.7 million. The loss related to the change in fair value of $1.6 million was recorded in other income (expense), net on the Consolidated Statements of Operations and Comprehensive Loss. The fair value of the Notes Option was recognized as an issuance premium for the Option Notes at inception.

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 utilized a "with-and-without" convertible bond model, modified to incorporate the interest rate reset feature, using the following key assumptions:


•	Credit Adjusted Discount Rate: The Company estimated a market-based discount rate of 24%.


•	Stock Price: The stock price was measured using 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.


•	Volatility: Based on the historical volatility of the Company's Common Stock, determined to be 42.6% as of the valuation date.


•	Term: Based on the time period of the Option Notes maturity, 3.7 years.


•	Risk Free Rate: Assumed to be 2.8% based on the Federal Reserve bond yield.

Based upon the modified convertible bond model utilized by management, the fair value of the interest rate reset feature was determined to be $3.0 million as of May 17, 2018 and was recognized as an issuance discount for the Option Notes at inception.

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 the make-whole 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 make-whole change of control derivative is treated as a liability, initially measured at fair value with subsequent changes in fair value recorded in earnings. Management utilized a probability-adjusted binomial lattice model to determine the fair value of the make-whole change of control derivative, with the following key assumptions:


•	Probability: The Company utilized a range between 0% and 10% to estimate the likelihood of occurrence.


•	Term: Based on the time period of the feature, 3.7 years.


•	Risk Free Rate: Assumed to be 2.8% based on U.S. Treasury bonds on the valuation date with a term commensurate with the remaining life of the change of control derivative.

Based on the binomial lattice model, the Company determined the fair value of the make-whole redemption provision as of May 17, 2018 to be $1.2 million. The fair value was recognized as an issuance discount of the Option Notes at inception. See "Notes Modifications" below.

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.

Additional modifications to the Option Notes are described under "Notes Modifications" below.

In accordance with the amendments described above, the minimum cash balance under the Notes covenant increased to $40.0 million upon filing of the Company's quarterly report on Form 10-Q on August 6, 2019.

On November 6, 2019, the Company and Starboard entered into an additional amendment to the Notes. The terms of the Notes were amended to provide the Company with an optional redemption right, whereby, in connection with a qualifying change of control pursuant to documentation entered into no later than August 5, 2020, the Company has the right to redeem the Notes in full in cash at a price equal to the sum of (i) the aggregate outstanding principal amount of the Notes, as of the consummation of the qualifying change of control, (ii) accrued interest, (iii) any other amounts owed pursuant to the Notes, and (iv) a 20% premium

on the aggregate outstanding principal amount of the Notes (the "qualifying change of control redemption"). The amendment also provided for an adjustment to the minimum cash balance required to be maintained by the Company. Upon execution of documentation providing for a qualifying change of control, the $40.0 million minimum cash balance would be reduced, on a dollar for dollar basis, for each dollar of cash interest paid to the holders of the Notes, subject to a $20.0 million minimum, until consummation of the qualifying change in control or, upon termination of the change in control, the shorter of 90 days after such termination or the consummation of a financing that enables the Company to maintain a minimum cash balance of $40.0 million. The amendment also modified the provisions of 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.

Management evaluated the qualifying change of control redemption feature, described above, and determined that it represented an embedded derivative that must be bifurcated and accounted for separately from the Notes. The qualifying change of control derivative is treated as a liability, initially measured at fair value with subsequent changes in fair value recorded in earnings. Management utilized a discounted cash flow model to determine the fair value of the qualifying change of control derivative, with the following key assumptions:


•	Probability: The Company utilized a range between 0% and 5% to estimate the likelihood of occurrence.


•	Term: Based on the time period of the feature, 0.7 years.


•	Credit Adjusted Discount Rate: The Company estimated a market-based discount rate of 25.0%.

Based on the discounted cash flow model, the Company determined the fair value of the qualifying change of control redemption provision as of November 6, 2019 to be $1.2 million.

In determining the amount to be recognized as an issuance discount of the Notes, the Company compared the fair value of the make-whole change of control redemption option of $2.2 million as of November 6, 2019 to the combined value of the make-whole and qualifying change of control redemption options immediately after the modification. The combined value of both redemption options after modification was $2.8 million. The difference in fair value of $0.6 million is combined with the existing unamortized discount of the Notes on the modification date and is amortized to interest expense over the remaining term of the modified debt. The Company recorded an additional $0.6 million in derivative liabilities due to this modification.

The balance of the Notes as of December 31, 2019 and 2018 was as follows:



			As of
			December 31, 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%	18.8%	$	153,500	$	(14,703	)	$	(2,706	)	$	136,091
Option Notes, due January 16, 2022	12.0%	14.9%	50,500		(2,365		)	(151		)	47,984
Total			$	204,000	$	(17,068	)	$	(2,857	)	$	184,075



			As of
			December 31, 2018
(In thousands, except interest rates)	Stated Interest Rate	Effective Interest Rate	Face Value		Original 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 $1.1 million in debt issuance costs and accreted $6.2 million in issuance discounts related to the total outstanding long-term debt during the year ended December 31, 2019. The Company amortized $1.0 million in debt issuance costs and accreted $4.8 million in issuance discounts related to the total outstanding long-term debt during the year ended December 31, 2018.

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 outstanding debt, was $172.4 million as of December 31, 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 (the "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 4 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

Pursuant to the Registration Rights Agreement with Starboard, 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 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. For additional information, refer to Footnote 15, Related Party Transactions.

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.

Issuance of Secured Term Note

On December 31, 2019 the Company's wholly owned subsidiary, Rentrak B.V., entered into an agreement with the Noteholder for the Secured Term Note for aggregate gross proceeds of $13.0 million, less issuance costs of $0.5 million. The Secured Term Note, which is cash collateralized, matures on December 31, 2021 and has an annual interest rate of 9.75%. Interest is payable in arrears on the last business day of each calendar month commencing on January 31, 2020.

The Secured Term Note contains certain affirmative and restrictive covenants with which Rentrak B.V. must comply, including (i) maintenance of a minimum cash collateral balance of $14.8 million, (ii) provision of certain financial statements, (iii) limitations on additional indebtedness and liens, (iv) limitations on repayment of debt, (v) limitations on repurchase of stock, and (vi) limitations on disposition of assets. Rentrak B.V. is in compliance with the Secured Term Note covenants as of December 31, 2019.



			As of
			December 31, 2019
(In thousands, except interest rates)	Stated Interest Rate	Effective Interest Rate	Face Value		Deferred Financing Costs			Net Carrying Value
Secured Term Note	9.75%	12.2%	$	13,000	$	(537	)	$	12,463

The Company concluded that the carrying amount reported in the Consolidated Balance Sheet ($12.5 million) approximates the fair value of the Secured Term Note as of December 31, 2019.

Revolving Credit Facility

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 December 31, 2019, $3.3 million in letters of credit are outstanding and are cash collateralized under the Security Agreement.

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 Consolidated Balance Sheets, with $1.8 million classified as short-term and $1.7 million classified as long-term as of December 31, 2019.

Future minimum payments related to the financing obligations under the failed sale-leaseback transaction as of December 31, 2019 are summarized below:

Stockholders' Equity

Stockholders' Equity Note [Abstract]

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 Warrants were exercisable by the holders at any time prior to the six-month anniversary of the Closing Date, as adjusted pursuant to the terms of the Series B-1 Warrants. The Series B-1 Warrants provided 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 could have been exercised for cash only. The Series B-1 Warrants expired in January 2020.

The Series B-2 Warrants are exercisable by the holders at any time prior to the 12-month anniversary of the Closing Date, as adjusted pursuant to the terms of the Series B-2 Warrants. 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 and may be exercised for cash only. If all of the Series B-2 Warrants have not been exercised prior to their expiration date, 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 Series 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 leading up to 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-2 Warrants, if applicable, will be 85.0% of the VWAP of the Common Stock on the date immediately preceding the expiration date of the Series B-2 Warrants.

The Series A Warrants are exercisable for a period of five years from the Closing Date and are currently exercisable into 5,457,026 shares of Common Stock, which is equal to the Initial Shares plus the number of 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 were not exercisable before September 21, 2019 and expire 90 days after the first anniversary of the Closing Date. CVI exercised the Series C Warrants on October 10, 2019. Because the VWAP of the Common Stock as of the date of exercise, discounted by 7.5%, was less than CVI's purchase price for the Initial Shares, the Company was 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 leading up to September

21, 2019, subject to a floor of 50.0% of the price per Initial Share, less (ii) the number of Initial Shares issued to CVI on the Closing Date. As a result of this exercise, the Company issued 2,728,513 shares of Common Stock to CVI on October 14, 2019. In addition, the number of shares issuable under the Company's Series A Warrants was increased by 2,728,513.

The exercise prices for the Series A and Series B-2 Warrants are subject to anti-dilution adjustment in certain circumstances. In addition, 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 20.0% 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 warrants 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 the Series B-2 Warrants 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 Warrants 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 Consolidated Balance Sheets, 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 as of the Closing Date:


•	Stock price: The stock price was measured using the fair value of the Common Stock on the Closing Date, 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.


•	Term: Management determined the term based on the time period of each warrant's maturity, between six months and five years from the Closing Date.


•	Change of control probability: The Company utilized a range between 0.0% and 10.0% to estimate the likelihood of occurrence.


•	Risk-free rate: Management assumed the risk-free rate to be between 1.7% and 2.1%, based on the U.S. Treasury bonds on the valuation date with terms commensurate with the terms of each warrant.


•	Cost of debt: Management assumed the cost of debt to be between 16.7% and 18.7% based on a synthetic credit rating analysis.


•	Dividend yield: Management assumed the dividend yield to be zero based on the historical payout of the Company.

Certain estimates above 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 the Closing Date to be the following:



(in thousands)	Warrants Liability
Series A Warrants	$	3,862
Series B-1 Warrants ⁽¹⁾	328
Series B-2 Warrants	376
Series C Warrants ⁽²⁾	6,232
Total	$	10,798
¹⁾ Series B-1 warrants expired in January 2020. ²⁾ Series C warrants were exercised in October 2019.

The Company recorded $1.8 million in accrued transaction costs in 2019, of which approximately $0.8 million was allocated to the warrants liability and recorded in general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Loss. The remaining transaction costs of $1.0 million were recorded in additional paid-in capital in the Consolidated Balance Sheets.

The estimated fair value of the warrants as of December 31, 2019 was $7.7 million. Refer to Footnote 6, Fair Value Measurements, for further information.

2007 Equity Incentive Plan

Pursuant to a merger agreement with Rentrak Corporation, upon the closing of the transaction in 2016, the Company assumed outstanding stock options under the Rentrak Corporation Amended and Restated 2005 Stock Incentive Plan and assumed outstanding stock options, RSUs and a stock appreciation right ("SAR") under the Rentrak Corporation 2011 Incentive Plan, and such stock options, RSUs and SAR were automatically converted into stock options, RSUs and SAR, respectively, with respect to shares of Common Stock, subject to appropriate adjustments to the number of shares and the exercise price (if applicable) of each such award.

In 2017, the Company's 2007 Equity Incentive Plan (the "2007 Plan") reached the end of its ten-year term and expired.

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. 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 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, 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 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 December 31, 2019 is 1,871,778.

Stock Options

During the year ended December 31, 2019, the Company's Compensation Committee approved and awarded 925,000 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	0.0%
Expected volatility	44.5	%	-	52.9%
Risk-free interest rate	1.3	%	-	2.7%
Expected life of options (in years)	5.21		-	10.00

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.

Risk-free interest rate — The Company used rates on the grant date of zero-coupon government bonds with maturities over periods covering the term of the awards, converted to continuously compounded forward rates.

Expected life of the options — This is the period of time that the options granted are expected to remain outstanding.

A summary of the options granted, exercised and expired during the years ended December 31, 2017, 2018 and 2019 is presented below:



	Number of shares		Weighted-Average Exercise Price

The intrinsic value of exercised stock options is calculated based on the difference between the exercise price and the quoted market price of the Company's Common Stock as of the close of the exercise date. There were 68,259 and 347,752 options exercised during the years ended December 31, 2019 and 2018, respectively. There were no options exercised during 2017. The aggregate intrinsic value for all options exercisable was $0.2 million, $1.5 million, and $17.2 million under the Company's stock plans as of December 31, 2019, 2018, and 2017 respectively. The aggregate intrinsic value for all options outstanding was $0.9 million, $0.7 million, and $17.2 million under the Company's stock plans as of December 31, 2019, 2018, and 2017, respectively. As of December 31, 2019, the total unrecognized compensation expense related to outstanding options is $1.9 million. There was no unrecognized compensation expense related to outstanding options as of December 31, 2018 and 2017.

Stock Appreciation Rights ("SAR")

The Company assumed an as-converted SAR with respect to 86,250 shares of Common Stock originally granted pursuant to the terms of Rentrak Corporation 2005 Stock Incentive Plan at an as-converted base price of $12.61 per share. The SAR expired unexercised on June 15, 2019.

Stock Awards

The Company's outstanding stock awards are comprised of RSUs, including both time-based and performance-based RSUs.

A summary of the stock awards granted, vested and forfeited during the years ended December 31, 2017, 2018 and 2019 is presented as follows. RSU awards with undelivered shares are classified as unvested until the date of delivery of the shares.



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, 2016	3,748		1,042,385		1,046,133		$	37.16

Forfeited	—		(529,767	)	(529,767	)	18.47
Unvested as of December 31, 2019	—		2,660,236		2,660,236		$	8.42

The aggregate intrinsic value for all unvested RSUs outstanding was $12.1 million, $21.3 million, and $22.0 million as of December 31, 2019, 2018, and 2017, respectively.

During the year ended December 31, 2019, the Company's Compensation Committee approved and awarded 1,603,866 time-based RSUs (of which 206,108 RSUs related to the settlement of an accrued 2018 annual incentive plan liability) and 975,000 market-based RSUs, which were valued using a Monte Carlo simulation analysis, to employees, directors and consultants of the Company. The Monte Carlo simulation analysis uses key assumptions including the performance period, grant date stock price, performance-based vesting hurdles and achievement requirements. Of the time-based RSUs, 581,491 shares vested immediately upon grant. The remaining time-based RSUs generally vest after one to three years contingent on continued service. The market-based RSUs vest over up to ten years based on the achievement of certain stock price hurdles.

As of December 31, 2019, total unrecognized compensation expense related to unvested RSUs was $13.7 million, which the Company expects to recognize over a weighted-average vesting period of approximately 5.06 years. The estimated forfeiture rate as of December 31, 2017, 2018, and 2019 was 10.0%. Changes in the estimates and assumptions relating to forfeitures and subsequent grants may result in material changes in stock-based compensation expense in the future.

During 2018, the Company's Compensation Committee approved and awarded 2,612,457 time-based RSUs, 191,800 performance-based RSUs, and 68,151 market-based RSUs under the 2018 Plan to employees, directors and consultants of the Company. Of the time-based RSUs, 1,493,288 vested immediately upon grant, including 165,086 shares related to the compensation of the Company's former CEO as part of his retirement and transition services agreement. The remaining time-based RSUs generally vest after three to four years contingent on continued service, and performance-based RSUs generally vest after three years based on achievement of pre-established revenue and adjusted earnings before interest income, interest expense, income taxes, depreciation and amortization (Adjusted EBITDA) goals. Market-based awards generally vest after three years based on the attainment of certain stock price hurdles.

Preferred Stock

The Company has 5,000,000 shares of $0.001 par value preferred stock authorized; no shares have been issued or were outstanding as of December 31, 2019 and 2018.

⁽¹⁾ Warrants liability includes Series A and Series B-2.

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 discount rate used to determine the present value of the instrument, the Common Stock price at the measurement date and the observable volatility of the Common Stock. The primary sensitivity for the make-whole and qualifying change of control redemption derivative liabilities is driven by the probability of the change of control.

The fair values of the Company's warrants liability 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 at rates commensurate with the remaining term of the related warrants. 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.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

In 2019, the Company concluded 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 combination of the discounted cash flow model and market value approach. The Company's reporting unit failed the goodwill impairment test; and as a result, the Company recorded a $224.3 million impairment charge.

The change in the carrying value of goodwill is as follows:

Goodwill	$	640,690
Accumulated Impairment	(224,272		)
Total	$	416,418

In addition, the Company recorded a $17.3 million impairment charge related to its strategic alliance intangible asset during 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 second 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 strategic 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 carrying values of the Company’s amortizable acquired intangible assets are as follows:

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 alleged damages in excess of $5.0 million, with any award to be apportioned among the defendants. On February 26, 2020, the Company and Full Circle reached an agreement with the plaintiffs to settle the complaints in full, with no admission of liability, in return for injunctive relief and payment of the plaintiffs' attorneys fees, to be covered by the Company's insurance. 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. 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, which was amended on September 30, 2019, purports to bring claims on behalf of all persons and entities that acquired securities of the Company between February 28, 2019 and August 7, 2019 and 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 in February and March 2019 material information concerning a disagreement relating to the Company's business strategy. 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 December 31, 2019. SEC Settlement On September 24, 2019, the Company announced a settlement with the SEC, resolving a previously disclosed investigation into financial accounting and disclosure practices between February 2014 and February 2016. The findings reached by the SEC related to revenue recognition and disclosure practices in 2014-2016, including contravention of civil antifraud and books and records provisions. The conduct occurred under prior management, including the Company's former Chief Executive Officer, Serge Matta. In agreeing to the terms of the settlement, which included a civil monetary penalty of $5.0 million and a cease-and-desist order (dated September 24, 2019) under Section 8A of the Securities Act of 1933 and Section 21C of the Exchange Act, the Company neither admitted nor denied the SEC's allegations. A separate proceeding against Mr. Matta was announced by the SEC, pursuant to which Mr. Matta agreed to pay a clawback to the Company of $2.1 million. The SEC considered the Company's cooperation during the investigation and its significant remedial efforts, including replacing the former Chief Executive Officer and other senior executives, constituting a new management team, implementing new and extensive internal control procedures and policies, and implementing a new, comprehensive compliance management system. In its order, the SEC also noted that all senior management and directors who were with the Company at the time of the conduct described in the order are no longer with the Company. Mr. Matta's $2.1 million clawback was paid to the Company in September 2019. The Company's first payment to the SEC (of the same amount, $2.1 million) was made in October 2019, to be followed by three equal payments of the remaining penalty amount plus post-judgment interest due 120, 240, and 360 days after the entry of the SEC's order. 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. On September 13, 2019, OFAC issued a letter stating that although potential violations may have occurred, OFAC had decided not to pursue a civil monetary penalty or take other enforcement action. The letter represented a final enforcement response from OFAC. In its letter, OFAC noted that the Company had taken a number of remedial compliance measures and detailed the compliance measures taken. 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. Similarly, certain of the Company's commercial contracts require it to indemnify contract counterparties under specified circumstances, and the Company may incur legal counsel fees and other costs in connection with these obligations.

Income Tax Benefit (Provision)

The Company recognized an income tax benefit of $1.0 million during the year ended December 31, 2019, which is comprised of current tax expense of $2.7 million primarily related to foreign taxes and a deferred tax benefit of $3.7 million related to temporary differences between the tax treatment and GAAP accounting treatment for certain items. Included within the total tax benefit is income tax expense of $17.3 million related to the increase in valuation allowance recorded against the Company's deferred tax assets to offset the tax benefit of the Company's operating losses in the U.S. and certain foreign jurisdictions. Also included in the total tax benefit are income tax adjustments of $58.6 million related to the impairment of goodwill and $15.2 million for permanent differences in the book and tax treatment of certain stock-based compensation, limitations on the deductibility of certain executive compensation, nondeductible interest expense on debt instruments and associated derivatives, and other nondeductible expenses.

These tax adjustments, along with state and local taxes and book losses in foreign jurisdictions where the income tax rate is substantially lower than the U.S. federal statutory rate, are the primary drivers of the annual effective income tax rate.

The Company recognized an income tax expense of $3.7 million during the year ended December 31, 2018, which is comprised of current tax expense of $1.7 million primarily related to foreign taxes and a deferred tax expense of $2.0 million related to temporary differences between the tax treatment and GAAP accounting treatment for certain items. Included within the total tax expense is an income tax expense of $19.0 million related to the increase in valuation allowance recorded against the Company's deferred tax assets to offset the tax benefit of the Company's operating losses in the U.S. and certain foreign jurisdictions. An income tax adjustment of $19.7 million has also been included for permanent differences in the book and tax treatment of certain stock-based compensation, limitations on the deductibility of certain executive compensation, nondeductible interest expense on debt instruments and associated derivatives, and other nondeductible expenses. These tax adjustments, along with state and local taxes and book losses in foreign jurisdictions where the income tax rate is substantially lower than the U.S. federal statutory rate, are the primary drivers of the annual effective income tax rate.

The Company recognized an income tax benefit of $2.7 million during the year ended December 31, 2017, which is comprised of current tax expense of $0.5 million primarily related to foreign taxes and a deferred tax benefit of $3.2 million related to temporary differences between the tax treatment and GAAP accounting treatment for certain items. Included within the total tax benefit is an income tax benefit of $8.3 million related to the impact of the TCJA provisions on the Company's U.S. deferred taxes, including the reduction in the corporate tax rate from 35% to 21% and a change in the Company's valuation allowance assessment. Also included is income tax expense of $126.1 million related to the increase in valuation allowance recorded against the Company's deferred tax assets to offset the tax benefit of the Company's operating losses in the U.S. and certain foreign jurisdictions. An income tax adjustment of $2.5 million has also been included for permanent differences in the book and tax treatment of certain stock-based compensation, meals and entertainment and other nondeductible expenses. These tax adjustments, along with having book losses in foreign jurisdictions where the income tax rate is substantially lower than the U.S. federal statutory rate, are the primary drivers of the annual effective income tax rate.

Deferred Income Taxes

Tax Valuation Allowance

As of December 31, 2019, and 2018, the Company had a valuation allowance of $219.6 million and $200.4 million, respectively, against certain deferred tax assets. The valuation allowance relates to the deferred tax assets of the Company's U.S. entities, including federal and state tax attributes and timing differences, as well as the deferred tax assets of certain foreign subsidiaries. The increase in the valuation allowance during 2019 is primarily related to operating losses incurred during the year. To the extent the Company determines that, based on the weight of available evidence, all or a portion of its valuation allowance is no longer necessary, the Company will recognize an income tax benefit in the period such determination is made for the reversal of the valuation allowance. If management determines that, based on the weight of available evidence, it is more-likely-than-not that all or a portion of the net deferred tax assets will not be realized, the Company may recognize income tax expense in the period such determination is made to increase the valuation allowance. It is possible that such reduction of or addition to the Company's valuation allowance may have a material impact on the Company's results from operations.

A summary of the deferred tax asset valuation allowance is as follows:



	As of
	December 31,
(In thousands)	2019			2018
Beginning Balance	$	200,366		$	181,334
Additions	19,832			19,356
Reductions	(591		)	(324		)
Ending Balance	$	219,607		$	200,366

Net Operating Loss and Credit Carryforwards

As of December 31, 2019, the Company had federal and state net operating loss carryforwards for tax purposes of $639.9 million and $1,391.3 million, respectively. These net operating loss carryforwards begin to expire in 2022 for federal income tax purposes and are expiring annually for state income tax purposes. The federal and certain state net operating losses generated after December 31, 2017 will have an indefinite carryforward period as a result of the TCJA. As of December 31, 2019, the Company had an aggregate net operating loss carryforward for tax purposes related to its foreign subsidiaries of $5.1 million, which will begin to expire in 2024.

As of December 31, 2019, the Company had research and development credit carryforwards of $3.2 million which begin to expire in 2025.

Under the provisions of Internal Revenue Code Section 382, certain substantial changes in the Company's ownership may result in a limitation on the amount of U.S. net operating loss carryforwards that can be utilized annually to offset future taxable income and taxes payable. A significant portion of the Company's net operating loss carryforwards are subject to an annual limitation under Section 382 of the Internal Revenue Code. Additionally, despite the net operating loss carryforwards, the Company may have a future tax liability due to foreign tax or state tax requirements.

Foreign Undistributed Earnings

As of December 31, 2019, the Company has certain foreign subsidiaries with accumulated undistributed earnings. The TCJA allows for a dividend received deduction resulting in no material U.S. federal income tax upon repatriation of these earnings. The Company intends to indefinitely reinvest these earnings, as well as future earnings from its foreign subsidiaries, to fund its international operations and therefore has not accrued any foreign withholding taxes or state income taxes.

Uncertain Tax Positions

For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company has unrecognized tax benefits, which are tax benefits related to uncertain tax positions which have been or will be reflected in income tax filings that have not been recognized in the financial statements due to potential adjustments by taxing authorities in the applicable jurisdictions. The Company's liabilities for unrecognized tax benefits, which include interest and penalties, were $1.6 million as of both December 31, 2019 and 2018. The remaining unrecognized tax benefits have reduced deferred tax balances. The amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate are $2.3 million, $2.5 million and $2.4 million as of December 31, 2019, 2018 and 2017, respectively, and include the federal tax benefit of state deductions. The Company anticipates that $0.4 million of unrecognized tax benefits will reverse during the next year due to the expiration of statutes of limitation.

Changes in the Company's unrecognized income tax benefits are as follows:



	As of December 31,
(In thousands)	2019			2018			2017
Beginning balance	$	2,560		$	2,508		$	3,608
Increase related to tax positions of prior years	14			167			81
Increase related to tax positions of the current year	53			90			88
Decrease related to tax positions of prior years	(84		)	(106		)	(1,064		)
Decrease due to lapse in statutes of limitations	(143		)	(99		)	(205		)
Ending balance	$	2,400		$	2,560		$	2,508

The Company recognizes interest and penalties related to income tax matters in income tax expense. As of both December 31, 2019 and 2018, accrued interest and penalties on unrecognized tax benefits were $0.7 million. The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. For income tax returns filed by the Company, the Company is no longer subject to U.S. federal examinations by tax authorities for years prior to 2016 or state and local tax examinations by tax authorities for years prior to 2015. Tax attribute carryforwards may still be adjusted upon examination by tax authorities.

Transactions with WPP

As of December 31, 2019 (based on public filings), WPP owned 11,319,363 shares of the Company's outstanding Common Stock, representing 16.2% ownership in the Company. On July 19, 2018, the Company filed a registration statement on Form S-1 with the SEC for the purpose of registering the shares of Common Stock owned by WPP in order to fulfill the Company's contractual obligations under a stockholders' rights agreement entered into by the Company and WPP in 2015. Refer to Footnote 4, Long-term Debt for more information. The Company provides WPP, in the normal course of business, services amongst its different products and receives various services from WPP supporting the Company's data collection efforts. In early 2015, there were a series of business and asset acquisitions and sales and issuances of Common Stock between the Company and WPP (giving rise to the stockholders' rights agreement described above) as well as a Subscription Receivable agreement that the Company entered into with GroupM, a WPP subsidiary.

In 2015, the Company and GroupM entered into an agreement in which GroupM agreed to a minimum commitment to purchase $20.9 million of the Company's products over five years, which was recorded as Subscription Receivable as contra equity within additional paid-in capital on the Consolidated Statements of Stockholders' Equity. In December 2017, the Company signed an amendment with GroupM in which GroupM agreed to purchase additional subscription services for $17.8 million over three years, which was offset by the $3.7 million Subscription Receivable that remained as of December 31, 2017. Upon fully utilizing the Subscription Receivable in September 2018, the Company began recognizing revenue under the amendment as the Company delivered products and services under the agreement. Total revenue recognized was $6.0 million and $2.0 million for the years ended December 31, 2019 and 2018, respectively.

In January 2016, as part of the Company's merger with Rentrak Corporation ("Rentrak"), the Company acquired two contracts with net present value of $14.5 million with WPP wholly-owned subsidiaries which were reflected as Subscription Receivable. The Company recorded the Subscription Receivable as contra equity within additional paid-in capital on the Consolidated Statements of Stockholders' Equity. As cash was received on the Subscription Receivable, additional paid-in capital was increased by the amount of cash received and the Company recognized imputed interest income. Effective August 31, 2018, the Company terminated one legacy Rentrak agreement which was originally reflected in Subscription Receivable and concurrently signed a new arrangement for $7.4 million for various subscription services over a three-year period. As of December 31, 2019, the balance of the Subscription Receivable is zero. The Company recorded $2.3 million and $0.8 million in revenues in the Consolidated Statements of Operations and Comprehensive Loss for the years ended December 31, 2019 and 2018, respectively.

The Company has a cancelable five-year agreement with Lightspeed, a WPP subsidiary, to conduct a proof of concept and follow-on program (the "Program") to demonstrate the capability of designing and deploying a program to collect browsing and demographic data for individual participating households. The agreement provides that the Company makes payments to Lightspeed of approximately $5.0 million per year through 2020. The Program is designed to be a comprehensive data collection effort across multiple in-home devices (e.g., television, streaming devices, computers, mobile phones, tablets, gaming devices and wearables) monitored via the installation of household internet routers ("Meters") in panelist households. The Meters collect and send the data back to the Company for use in its Total Home Panel product. Under the terms of the Program, Lightspeed is paid to manage the operational aspects of panel recruitment, compliance, inventory management, support and collection of panel demographic data.

The Company's results from transactions with WPP and its affiliates, as reflected in the Consolidated Statements of Operations and Comprehensive Loss, are detailed below:

Transactions with Starboard

On January 16, 2018, the Company entered into certain agreements with Starboard, then a beneficial owner of more than five percent of the Company's outstanding Common Stock. Refer to Footnote 4, Long-term Debt, for further information regarding these agreements and the Company's issuance of senior secured convertible notes to Starboard in 2018. As a result of these agreements and the transactions contemplated thereby, Starboard ceased to be a beneficial owner of more than five percent of the Company's outstanding Common Stock on January 16, 2018.

On April 18, 2018, the Company amended a prior agreement with Starboard, dated as of September 28, 2017 (the "September Agreement"), pertaining to the membership and composition of the Company's Board of Directors (the "Board"). Pursuant to the amendment, the Company and Starboard agreed that, effective as of the Company's annual meeting of stockholders on May 30, 2018, the size of the Board would be fixed at eight members.

Restructuring and Related Activities [Abstract]

Organizational Restructuring

In December 2017, the Company implemented a reduction in force plan ("2017 Restructuring Plan") that resulted in the termination of approximately 10% of its workforce. The reduction in force was implemented following management's determination to reduce its staffing levels and exit certain geographic regions, in order to enable the Company to decrease its global costs and more effectively align resources to business priorities. Total restructuring expense recognized for the 2017 Restructuring Plan was $11.8 million and this 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"). This additional restructuring effort resulted in the termination of one operating lease, the extension of the lease related to the Company's headquarters, and the sublease of three offices. In connection with the 2018 Restructuring Plans, the Company incurred total exit-related costs of $8.1 million. $10.3 million was recorded in 2018, and $2.2 million was reversed in 2019 related to an employee who ultimately did not exit the Company. These plans were complete as of December 31, 2019.

In May 2019, the Company implemented an additional reduction in force plan ("May 2019 Restructuring Plan") in order to reduce costs and more effectively align resources with business priorities. Together with attrition, the May 2019 Restructuring Plan resulted in the termination of approximately 10% of the Company's workforce. In connection with the May 2019 Restructuring Plan, the Company incurred total exit-related costs of $3.1 million during the year ended December 31, 2019. The Company does not expect to incur any future expenses related to this plan.

In August 2019, the Company implemented a further reduction in force plan ("August 2019 Restructuring Plan") in order to reduce costs and more effectively align resources with business priorities. The August 2019 Restructuring Plan resulted in the termination of approximately 8% of the Company's workforce. In connection with the August 2019 Restructuring Plan, the Company incurred total exit-related costs of $2.5 million.

As of December 31, 2019, the total remaining accrual for restructuring is $1.0 million, all of which is current. The tables below summarize the balance of accrued restructuring expenses and the changes in the accrued amounts for each period presented.

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

Reclassification

Use of Estimates and Judgments in the Preparation of the Consolidated Financial Statements

Fair Value Measurements

Level 1 - observable inputs such as quoted prices in active markets;

Level 2 - inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 - unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

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 discount rate used to determine the present value of the instrument, the Common Stock price at the measurement date and the observable volatility of the Common Stock. The primary sensitivity for the make-whole and qualifying change of control redemption derivative liabilities is driven by the probability of the change of control.
