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.

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:

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.

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 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. The fair value of the Company's Secured Term Note is determined using future cash flows that are discounted back at a risk-free rate commensurate with the expected remaining term of the debt. The fair value of the Company's interest make-whole derivative is estimated using forward projections of estimated cash payments at the closing date discounted back to the valuation date at rates commensurate with the estimated remaining term of the related derivative.

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 represents the Company's cash collateral requirements under the Secured Term Note, outstanding letters of credit, and corporate credit card obligations. As of December 31, 2020 and 2019, the Company had $19.6 million and $20.2 million of restricted cash, respectively, of which $0.5 million and $1.0 million was held in certificates of deposit as of December 31, 2020 and 2019, respectively. As of December 31, 2020, certificates of deposit in the amount of $0.1 million will mature within one year.

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 adjusted for current conditions or expected future conditions based on reasonable and supportable forecasts, a specific review of all significant outstanding receivables, an assessment of company-specific credit conditions and general economic conditions. For 2020, management considered the impact of the COVID-19 pandemic, including customer payment delays and requests from customers to revise contractual payment terms, in determining the Company's allowance for doubtful accounts which resulted in an increase of the allowance.

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, 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, 2020, 2019 and 2018 the Company capitalized $15.0 million, $11.9 million, and $9.6 million in internal-use software costs, respectively. The Company depreciated $9.1 million, $4.8 million and $1.3 million in capitalized internal-use software costs during the years ended December 31, 2020 2019, and 2018 respectively.

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 $3.2 million and $1.0 million of implementation costs during the years ended December 31, 2020 and 2019. Amortization of these costs has not commenced as the implementation activities are not complete.

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 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'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.

The Company applies the provisions of Accounting Standards Codification ("ASC") 360, Property, Plant and Equipment, to determine whether right-of-use ("ROU") assets and related long-lived assets may be impaired. The Company evaluates its ROU and long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of such assets may not be recoverable. For facility lease ROU and related long-lived assets, the Company compares the estimated undiscounted cash flows generated by a sublease to the current carrying value of the ROU and related long-lived assets. If the undiscounted cash flows are less than the carrying value of the ROU and related long-lived assets, the Company records an impairment loss equal to the excess of the ROU and long-lived assets' carrying value over their fair value consistent with other long-lived assets.

The Company recorded a $4.7 million non-cash impairment charge related to its ROU assets, and related leasehold improvements, with corresponding reductions of $2.8 million and $1.9 million to the operating right-of-use assets and property and equipment, net line items, respectively, in the Consolidated Balance Sheet. The impairment charge was driven by changes in the Company's projected undiscounted cash flows for certain properties, primarily as a result of changes in the real estate market related to the COVID-19 pandemic, that led to an increase in the estimated marketing time, and a reduction of expected receipts, for properties on the market for sublease. The fair value of these ROU assets, and related leasehold improvements, was estimated using an income approach and a discount rate of 12%.

In 2019, the Company issued warrants to CVI in connection with the private placement described in Footnote 1, Organization. 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.

The Company adopted ASC 842, Leases, with an initial application date of January 1, 2019, using the modified retrospective method with optional transaction 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. The adoption of ASC 842 did not have a material impact on the Consolidated Statements of Operations and Comprehensive Loss.

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. 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 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 10.6% to 15.0% 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.

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.

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.

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 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. 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.

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. In some instances, the Company may provide free distinct goods or services as a form of non-cash consideration to the counterparty. 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.

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.

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.

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 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.

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.

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.

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 ("EPS") 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 the 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.

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.

In December 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the "TCJA") was signed into law. The Company 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 consolidated financial statements.

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 in April 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.

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 adopted the new standard effective January 1, 2020, and the standard did not 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 adopted the new standard effective January 1, 2020, and the standard did not have a material impact on the Consolidated Financial Statements or related disclosures based on historical collection trends, the financial condition of payment partners, and external market factors.

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.
