(2) Summary of Significant Accounting Policies

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments, including money market funds and marketable debt securities, with maturities of three months or less at the time of acquisition.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recognized when the right to consideration becomes unconditional and are recorded net of an allowance for doubtful accounts. Such allowance aggregated $25 million and $21 million at December 31, 2019 and 2018, respectively. Our customer invoices are generally due 30 days from the time of invoicing. For accounts outstanding longer than the contractual payment terms, the Company determines an allowance by considering a number of factors,

including the length of time trade accounts receivable are past due, previous loss history, a specific customer’s ability to pay its obligations to us, and the condition of the general economy and industry as a whole.

Investments

All marketable debt and equity securities held by the Company are carried at fair value, generally based on quoted market prices. Fair values are determined for each individual security in the investment portfolio. Unrealized gains and losses, net of taxes, arising from changes in fair value are reported in accumulated other comprehensive income (loss) as a component of equity.

For those investments in which the Company has the ability to exercise significant influence, the equity method of accounting is used.  Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses of the affiliate as they occur rather than as dividends or other distributions are received.  Losses are limited to the extent of the Company’s investment in, advances to and commitments for the investee.  In the event the Company is unable to obtain accurate financial information from an equity affiliate in a timely manner, the Company records its share of earnings or losses on a lag.  

For those equity securities without readily determinable values, the Company elected the measurement alternative (defined as the cost of the security, adjusted for changes in fair value when there are observable prices, less impairments).

The classification of investments is determined at the time of purchase and reevaluated at each balance sheet date. We invest in highly-rated securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. The policy requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss and providing liquidity of investments sufficient to meet our operating and capital spending requirements and debt repayments.

Marketable debt securities are classified as either short-term or long-term based on each instrument’s underlying contractual maturity date and as to whether and when we intend to sell a particular security prior to its maturity date. Marketable debt securities with maturities greater than 90 days at the date of purchase and 12 months or less remaining at the balance sheet date will be classified as short-term and marketable debt securities with maturities greater than 12 months from the balance sheet date will generally be classified as long-term. We classify our marketable equity securities, limited to money market funds and mutual funds, as either a cash equivalent, short-term or long-term based on the nature of each security and its availability for use in current operations.

Realized gains and losses on the sale of securities are determined by specific identification of each security’s cost basis. We may sell certain of our marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration and liquidity and duration management. The weighted average maturity of our total invested cash shall not exceed 18 months, and no security shall have a final maturity date greater than three years.

Derivative Instruments

All of the Company’s derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive earnings and are recognized in the statement of operations when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings. If the derivative is not designated as a hedge, changes in

the fair value of the derivative are recognized in earnings. None of the Company’s derivatives are currently designated as hedges.

The fair value of certain of the Company’s derivative instruments are estimated using the Black-Scholes-Merton model. The Black-Scholes-Merton model incorporates a number of variables in determining such fair values, including expected volatility of the underlying security and an appropriate discount rate. The Company obtains volatility rates from pricing services based on the expected volatility of the underlying security over the remaining term of the derivative instrument. A discount rate is obtained at the inception of the derivative instrument and updated each reporting period, based on the Company’s estimate of the discount rate at which it could currently settle the derivative instrument. The Company considered its own credit risk as well as the credit risk of its counterparties in estimating the discount rate. Management judgment is required in estimating the Black-Scholes-Merton model variables.

Property and Equipment

Property and equipment consists of the following (amounts in millions):

​

Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is three to five years for computer equipment and furniture, office equipment and other. Leasehold improvements are depreciated using the straight-line method, over the shorter of the estimated useful life of the improvement or the remaining term of the lease.

Leases

The Company, through its consolidated companies, leases facilities in several countries around the world and certain equipment under non-cancelable lease agreements.  Refer to note 8 for a discussion on accounting for leases and other financial disclosures.

Intangible Assets

Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment upon certain triggering events. Goodwill and other intangible assets with indefinite useful lives (collectively, "indefinite lived intangible assets") are not amortized, but instead are tested for impairment at least annually. Our annual impairment assessment of our indefinite-lived intangible assets is performed during the fourth quarter of each year.

The accounting guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. The accounting guidance also allows entities the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative impairment test. The entity may resume performing the qualitative assessment in any subsequent period.

In evaluating goodwill on a qualitative basis, the Company reviews the business performance of each reporting unit and evaluates other relevant factors as identified in the relevant accounting guidance to determine whether it was more likely than not that an indicated impairment exists for any of our reporting units. The Company considers whether there are any negative macroeconomic conditions, industry specific conditions, market changes, increased competition, increased costs in doing business, management challenges, the legal environments and how these factors might impact company specific performance in future periods. As part of the analysis, the Company also considers fair value determinations for certain reporting units that have been made at various points throughout the current year and prior year for other purposes. If, based on the qualitative analysis, it is more likely than not that an impairment exists, the Company performs the quantitative impairment test.

The quantitative goodwill impairment test compares the estimated fair value of a reporting unit to its carrying value. Developing estimates of fair value requires significant judgments, including making assumptions about appropriate discount rates, perpetual growth rates, relevant comparable market multiples, public trading prices and the amount and timing of expected future cash flows. The cash flows employed in TripCo's valuation analyses, where applicable, are based on management's best estimates considering current marketplace factors and risks as well as assumptions of growth rates in future years. There can be no assurance that actual results will approximate these forecasts.

The accounting guidance also permits entities to first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset, other than goodwill, is impaired. The accounting guidance also allows entities the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to the quantitative impairment test. The entity may resume performing the qualitative assessment in any subsequent period. If the qualitative assessment supports that it is more likely than not that the carrying value of the Company’s indefinite-lived intangible assets, other than goodwill, exceeds its fair value, then a quantitative assessment is performed. If the carrying value of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. See note 6 for discussion of goodwill and trademark impairments.

Websites and Internal Use Software Development Costs

Certain costs incurred during the application development stage related to the development of websites and internal use software are capitalized and included in other intangible assets subject to amortization. Capitalized costs include internal and external costs, if direct and incremental, and deemed by management to be significant. Costs related to the planning and post-implementation phases of software and website development are expensed as these costs are incurred. Maintenance and enhancement costs (including those costs in the post-implementation stages) are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software resulting in added functionality, in which case the costs are capitalized.

​

Impairment of Long-lived Assets

The Company periodically reviews the carrying amounts of its property and equipment and its intangible assets (other than goodwill and indefinite-lived intangibles) to determine whether current events or circumstances indicate that such carrying amounts may not be recoverable. If the carrying amount of the asset group is greater than the expected undiscounted cash flows to be generated by such asset group, including its ultimate disposition, an impairment adjustment

is recognized. Such adjustment is measured by the amount that the carrying value of such asset groups exceeds their fair value. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows using an appropriate discount rate. Considerable management judgment is necessary to estimate the fair value of asset groups. Accordingly, actual results could vary significantly from such estimates. Asset groups to be disposed of are carried at the lower of their financial statement carrying amount or fair value less costs to sell.

​

Noncontrolling Interests

Noncontrolling interest relates to the equity ownership interest in Tripadvisor that the Company does not own. The Company reports noncontrolling interests of consolidated companies within equity in the consolidated balance sheets and the amount of net income attributable to the parent and to the noncontrolling interest is presented in the consolidated statements of operations. Also, changes in ownership interests in consolidated companies in which the Company maintains a controlling interest are recorded in equity.

​

Foreign Currency Translation and Transaction Gains and Losses

The functional currency of the Company is the United States (“U.S.”) dollar. The functional currency of the Company’s foreign operations generally is the applicable local currency for each foreign subsidiary. Assets and liabilities of foreign subsidiaries are translated at the spot rate in effect at the applicable reporting date, and the consolidated statements of operations are translated at the average exchange rates in effect during the applicable period. The resulting unrealized cumulative translation adjustment, net of applicable income taxes, is recorded as a component of accumulated other comprehensive earnings (loss) in equity.

Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. Subsequent changes in exchange rates result in transaction gains and losses which are reflected in the accompanying consolidated statements of operations and comprehensive earnings (loss) as unrealized (based on the applicable period-end exchange rate) or realized upon settlement of the transactions.

Accordingly, we have recorded foreign currency exchange losses of $3 million and $6 million and gains of $1 million for the years ended December 31, 2019, 2018, and 2017, respectively, in other, net on our consolidated statements of operations.

Revenue Recognition

Tripadvisor generates all of its revenue from contracts with customers. It recognizes revenue when it satisfies a performance obligation by transferring control of the promised services to a customer in an amount that reflects the consideration that it expects to receive in exchange for those services. When Tripadvisor acts as an agent in the transaction, it recognizes revenue for only its commission on the arrangement. Tripadvisor determines revenue recognition through the following steps:

​

​

At contract inception, Tripadvisor assesses the services promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a service (or bundle of services) that is distinct. To

identify the performance obligations, Tripadvisor considers all of the services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. There was no significant revenue recognized in the years ended December 31, 2019 and 2018 related to performance obligations satisfied in prior periods. Tripadvisor has applied a practical expedient and does not disclose the value of unsatisfied performance obligations that have an original expected duration of less than one year, and Tripadvisor does not have any material unsatisfied performance obligations over one year. The value related to Tripadvisor’s remaining or partially satisfied performance obligations relates to subscription services that are satisfied over time or services that are recognized at a point in time, but not yet achieved.  The timing of services, invoicing and payments do not include a significant financing component. Tripadvisor’s customer invoices are generally due 30 days from the time of invoicing.

​

Tripadvisor recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. Although the substantial majority of its contract costs have an amortization period of less than one year, Tripadvisor has determined contract costs arising from certain sales incentives have an amortization period in excess of one year given the high likelihood of contract renewal. Sales incentives are not paid upon renewal of these contracts and therefore are not commensurate with the initial sales incentive costs. Total capitalized costs to obtain a contract were approximately $4 million and $2 million as of December 31, 2019 and 2018, respectively. These contract costs are amortized on a straight-line basis over the estimated customer life, which is based on historical customer retention rates. Amortization expense recorded to selling, general and administrative expense during years ended December 31, 2019 and 2018, respectively, were $1 million and not material. Tripadvisor assesses such assets for impairment when events or circumstances indicate that the carrying amount may not be recoverable.

​

The recognition of revenue may require the application of judgment related to the determination of the performance obligations, the timing of when the performance obligations are satisfied and other areas. The determination of Tripadvisor’s performance obligations does not require significant judgment given that it generally does not provide multiple services to a customer in a transaction, and the point in which control is transferred to the customer is readily determinable. In instances where Tripadvisor recognizes revenue over time, it generally has either a subscription service that is recognized over time on a straight-line basis using the time-elapsed output method, or based on other output measures that provide a faithful depiction of the transfer of Tripadvisor’s services. When an estimate for cancellations is included in the transaction price, the estimate is based on historical cancellation rates. There have been no significant adjustments to Tripadvisor’s cancellation estimates and the cancellation estimates are not material. Taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue–producing transaction, that are collected by Tripadvisor from a customer, are reported on a net basis, or in other words, excluded from revenue on its consolidated financial statements, which is consistent with prior periods. The application of Tripadvisor’s revenue recognition policies and a description of the principal activities from which it generates revenue, are presented below.  

​

Hotels, Media & Platform Segment

Tripadvisor-branded Hotels Revenue. Tripadvisor’s largest source of Hotel, Media & Platform segment revenue is generated from click-based advertising on Tripadvisor-branded websites, which is primarily comprised of contextually-relevant booking links to its travel partners’ websites. Click-based advertising is generally priced on a cost-per-click, or “CPC,” basis, with payments from travel partners determined by the number of travelers who click on a link multiplied by the CPC rate for each specific click as determined in a dynamic, competitive auction process.

In addition, Tripadvisor offers subscription-based advertising to hotel partners, owners of B&Bs and other specialty lodging properties. Subscription-based advertising services are predominantly sold for a flat fee for a contracted

period of time of one year or less and revenue is recognized on a straight-line basis over the period of the subscription service as efforts are expended evenly throughout the contract period.

Tripadvisor also offers travel partners the opportunity to advertise and promote their business through hotel sponsored placements on Tripadvisor’s websites. This service is generally priced on a fixed CPC basis, with payments from travel partners determined by the number of travelers who click on the sponsored link multiplied by the CPC rate for each specific click.

To a lesser extent, Tripadvisor generates transaction revenue from Tripadvisor’s hotel instant booking feature, which enables hotel shoppers to book directly with a travel partner, with the latter serving as the merchant of record for the transaction, without leaving Tripadvisor’s website. Tripadvisor earns a commission from its travel partners for each traveler that completes a hotel reservation on Tripadvisor’s website, based on a pre-determined contractual commission rate.

Tripadvisor-branded Display and Platform Revenue. Tripadvisor offers travel partners the ability to promote their brands through display-based advertising placements on Tripadvisor’s websites across all of its segments and business units. Tripadvisor display-based advertising clients are predominantly direct suppliers of hotels, airlines and cruises, as well as destination marketing organizations. Tripadvisor also sells display-based advertising to online travel agencies and other travel related businesses, as well as advertisers from non-travel categories. Display-based advertising is sold predominantly on a cost per thousand impressions basis.

Experiences & Dining Segment

Tripadvisor provides information and services that allow consumers to research and book activities and attractions in popular travel destinations primarily through Viator, Tripadvisor’s dedicated Experiences offering, and on the Tripadvisor website and mobile apps.  Tripadvisor generates commissions for each booking transaction it facilitates through its online reservation system.

Tripadvisor also provides information and services for consumers to research and book restaurants in popular travel destinations through its dedicated restaurant reservations offering, TheFork, and on Tripadvisor-branded websites and mobile apps. TheFork is an online restaurant booking platform operating on a number of websites with a network of restaurant partners located primarily across the United Kingdom (the “U.K.”), Europe, Australia, and South America. Tripadvisor primarily generates transaction fees (or per seated diner fees) that are paid by restaurants for diners seated primarily from bookings through TheFork’s online reservation system.

Other

Tripadvisor provides information and services that allow travelers to research and book vacation and short-term rental properties. The Rentals offering generates revenue primarily by offering individual property owners and managers the ability to list their properties on Tripadvisor’s websites and mobile apps thereby connecting with travelers through a free-to-list, commission-based option or, to a lesser extent, by an annual subscription-based fee structure. Tripadvisor earns commissions associated with rental transactions through its free-to-list model from both the traveler, and the property owner or manager.

In addition, Other also includes revenue generated from flights, cruises, and car offerings on Tripadvisor, as well as revenue from non-Tripadvisor-branded websites not otherwise described above, such as www.bookingbuddy.com,

www.cruisecritic.com, www.onetime.com and www.smartertravel.com, and Tripadvisor China, which primarily includes click-based advertising and display-based advertising revenue.

Practical Expedients and Exemptions

​

Tripadvisor expenses costs to obtain a contract as incurred, such as sales incentives, when the amortization period would have been one year or less.

Tripadvisor does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

Disaggregation of Revenue

Tripadvisor disaggregates revenue from contracts with customers into major products/revenue sources. Tripadvisor has determined that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Revenue is recognized primarily at a point in time for all reported segments.

​

​

The following table provides information about the opening and closing balances of accounts receivable and contract assets from contracts with customers (in millions):

​

Accounts receivable are recognized when the right to consideration becomes unconditional. Contract assets are rights to consideration in exchange for services that Tripadvisor has transferred to a customer when that right is conditional on something other than the passage of time, such as commission payments that are contingent upon the completion of the service by the principal in the transaction. Contract liabilities generally include payments received in advance of performance under the contract, and are realized as revenue as the performance obligation to the customer is satisfied, which Tripadvisor presents as deferred revenue on its consolidated balance sheets. As of January 1, 2019 and 2018, Tripadvisor had $63 million and $59 million, respectively, recorded as deferred revenue on its consolidated balance sheet, of which $61 million and $57 million, respectively, was recognized into revenue and $2 million was refunded due to cancellations by travelers during both years ended December 31, 2019 and 2018.  The difference between the opening and closing balances of Tripadvisor’s deferred revenue primarily results from the timing differences between when Tripadvisor receives customer payments and the time in which Tripadvisor satisfies its performance obligations. The difference between the opening and closing balances of Tripadvisor’s contract assets primarily results from the timing difference between when Tripadvisor satisfies its performance obligations and the time when the principal completes the service in the transaction. There were no significant changes in contract assets or deferred revenue during the years ended December 31, 2019 and 2018, related to business combinations, impairments, cumulative catch-ups or other material adjustments.

Operating Expense

Operating expenses consist primarily of certain technology and content expenses, including personnel and overhead expenses which include salaries, benefits and bonuses for salaried employees and contractors engaged in the design, development, testing content support and maintenance of Tripadvisor’s websites and mobile apps. Operating expense also includes, to a lesser extent, costs of services which are expenses that are closely correlated or directly related to service revenue generated, including credit card and other booking transaction payment fees, data center costs, costs associated with prepaid tour tickets, ad serving fees, flight search fees and other transactions. Other costs include licensing, maintenance expense, computer supplies, telecom costs, content translation and localization costs and consulting costs.

General and Administrative

General and administrative expenses consist primarily of personnel and related overhead costs, including personnel engaged in leadership, finance, legal and human resource functions as well as professional service fees and other fees including audit, legal, tax and accounting, and other costs including bad debt expense and non-income taxes, such as sales, use and other non-income related taxes.

Selling and Marketing

Selling and marketing expenses primarily consist of direct costs, including traffic generation costs from search engine marketing, or SEM, and other online traffic acquisition costs, syndication costs and affiliate program commissions, social media costs, brand advertising (including television and other offline advertising), promotions and public relations. In addition, our indirect sales and marketing expense consists of personnel and overhead expenses, including salaries, commissions, benefits, and bonuses for sales, sales support, customer support and marketing employees.

Tripadvisor incurs advertising expense consisting of traffic generation costs from SEM and other online traffic costs, affiliate program commissions, display advertising, social media, other online and offline (primarily television) advertising expense, and promotions and public relations to promote its brands. Costs associated with communicating the advertisements are expensed in the period in which the advertisement takes place. Production costs associated with advertisements are expensed in the period in which the advertisement first takes place.

Stock-Based Compensation

As more fully described in note 11, TripCo grants to its directors, employees and employees of its subsidiaries restricted stock and options (collectively, “Awards”) to purchase shares of TripCo common stock. TripCo measures the cost of employee services received in exchange for an equity classified Award (such as stock options and restricted stock) based on the grant-date fair value of the Award, and recognizes that cost over the period during which the employee is required to provide service (usually the vesting period of the Award). TripCo measures the cost of employee services received in exchange for a liability classified Award based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date. Certain outstanding awards that were previously granted by Qurate Retail were assumed by TripCo upon the completion of the TripCo Spin-Off. Additionally, Tripadvisor is a consolidated company and has issued stock-based compensation to its employees related to its common stock. The consolidated statements of operations include stock-based compensation related to TripCo Awards and Tripadvisor equity awards.

Included in the accompanying consolidated statements of operations are the following amounts of stock-based compensation for the years ended December 31, 2019, 2018 and 2017 (amounts in millions):

​

During the years ended December 31, 2019, 2018 and 2017, Tripadvisor capitalized $19 million, $13 million and $13 million, respectively, of stock-based compensation expense as internal-use software and website development costs.  

Income Taxes

The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying value amounts and income tax bases of assets and liabilities and the expected benefits of utilizing net operating loss and tax credit carryforwards. The deferred tax assets and liabilities are calculated using enacted income tax rates in effect for each taxing jurisdiction in which the Company operates for the year in which those temporary differences are expected to be recovered or settled. Net deferred tax assets are then reduced by a valuation allowance if the Company believes it more likely than not that such net deferred tax assets will not be realized. We consider all relevant factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as assessing available tax planning strategies. The effect on deferred tax assets and liabilities of an enacted change in tax rates is recognized in income in the period that includes the enactment date. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law, tax sharing agreements or variances between our actual and anticipated operating results, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates.

When the tax law requires interest to be paid on an underpayment of income taxes, the Company recognizes interest expense from the first period the interest would begin accruing according to the relevant tax law. Such interest expense is included in income tax (expense) benefit in the accompanying consolidated statements of operations. Any accrual of penalties related to underpayment of income taxes on uncertain tax positions is included in income tax (expense) benefit in the accompanying consolidated statements of operations.

We recognize in our consolidated financial statements the impact of a tax position, if that position is more likely than not to be sustained upon an examination, based on the technical merits of the position.

Deferred Merchant Payables

In Tripadvisor’s Rentals free-to-list model and its Experiences businesses, Tripadvisor receives cash from travelers at the time of booking and it records these amounts, net of commissions, on its consolidated balance sheets as deferred merchant payables. Tripadvisor pays the suppliers, or the vacation rental owners and tour providers, respectively, after the travelers’ use. Therefore, it receives cash from the traveler prior to paying the suppliers and this operating cycle represents a working capital source or use of cash to Tripadvisor. Tripadvisor’s deferred merchant payables balance was $159 million and $164 million for the years ended December 31, 2019 and 2018, respectively.

Certain Risks and Concentrations

The Tripadvisor business is subject to certain risks and concentrations, including concentrations related to dependence on relationships with its customers. For the years ended December 31, 2019, 2018 and 2017, Tripadvisor’s two most significant travel partners, Expedia Group Inc. (“Expedia”) and Booking Holdings Inc., which each accounted for more than 10% of Tripadvisor’s consolidated revenue and combined accounted for approximately 33%, 37% and 43%, respectively, of its total revenue.

​

Contingent Liabilities

Periodically, the Company reviews the status of all significant outstanding matters to assess any potential financial exposure. When (i) it is probable that an asset has been impaired or a liability has been incurred and (ii) the amount of the loss can be reasonably estimated, we record the estimated loss in our consolidated statements of operations. The Company provides disclosure in the notes to the consolidated financial statements for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the consolidated financial statements. Significant judgment is required to determine the probability that a liability has been incurred and whether such liability is reasonably estimable. Accruals are based on the best information available at the time which can be highly subjective. The final outcome of these matters could vary significantly from the amounts included in the accompanying consolidated financial statements.

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income (loss), cumulative foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities, net of tax.

​

Earnings (Loss) per Common Share (EPS)

Basic earnings (loss) per common share (“EPS”) is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented. Excluded from EPS for each of the years ended December 31, 2019, 2018 and 2017 are 2 million potential common shares because their inclusion would be antidilutive.

​

​

Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company considers (i) recoverability and recognition of goodwill, intangible and long-lived assets and (ii) accounting for income taxes to be its most significant estimates.
