2. Summary of Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements reflect the application of significant accounting policies as described below and elsewhere in these notes to the unaudited condensed consolidated financial statements.

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial reporting and applicable quarterly reporting regulations of the Securities and Exchange Commission ("SEC"). In management's opinion, the accompanying interim unaudited condensed consolidated financial statements include all adjustments necessary for a fair statement of the financial position of the Company as of September 30, 2019,2020, the results of operations for the three and nine months ended September 30, 20192020 and 2018,2019, cash flows for the nine months ended September 30, 20192020 and 2018,2019, and stockholders' equity for the three and nine months ended September 30, 20192020 and 2018.2019.

Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 20182019 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 20182019 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP.

Certain prior year amounts have been reclassified for consistency with the current year presentation. This insignificant reclassification had no effect on the reported results of operations. License revenue and license cost of revenue are now combined with subscription revenue and subscription cost of revenue, respectively.

Risks and uncertainties

Coronavirus ("COVID-19") continues to spread throughout the U.S. and the world and compliance with the various containment measures implemented by governmental authorities has impacted the Company's business, as well as the businesses of its customers, suppliers and other counterparties, and this impact could last for an indefinite period of time. There are no comparable recent events that provide guidance as to the effect of the spread of COVID-19 as a global pandemic, and as a result, the Company is unable to predict the full impact that COVID-19 will have on its results from operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures. For a full discussion on the ongoing impact of COVID-19 to the Company's business, please see "We must successfully navigate the demand, supply and operational challenges associated with the ongoing coronavirus (COVID-19) pandemic" under Part II, Item 1A of this Quarterly Report on Form 10-Q.

Changes in accounting policies

The Company has consistently applied these    There have been no material changes in the Company’s significant accounting policies and their application as compared to all periods presentedthe significant accounting policies described in these consolidated financial statements,the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, except for the Company's adoption of certain accounting standards described in more detail under "Recently adopted accounting pronouncements" in this Note 2 below.

Basis
Table of consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and a subsidiary where the Company exercises control. All intercompany transactions and balances have been eliminated in consolidation. The functional currency of PROS France SAS ("PROS France") is the euro. The financial statements of this subsidiary are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, historical rates of exchange for equity, and average rates of exchange for the period for revenue and expenses. Translation gains (losses) are recorded in accumulated other comprehensive loss as a component of stockholders' equity.

Dollar amounts

The dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars, except per share amounts, or as noted within the context of each footnote disclosure.

Use of estimates

The Company makes estimates and assumptions in the preparation of its unaudited condensed consolidated financial statements, and its estimates and assumptions may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. The complexity and judgment required in the Company's estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in determining the nature and timing of satisfaction of performance obligations and determining the standalone selling price of performance obligations, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for doubtful accounts, operating lease right-of-use assets and operating lease liabilities, useful lives of assets, depreciation and amortization, income taxes and deferred tax asset valuation, valuation of stock options, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. The critical accounting policies related to estimates and judgments are discussed in the Annual Report under management's discussion and analysis of financial condition and results of operations and are also discussed under Item 2 "Management's discussion and analysis of financial condition and results of operations".Contents

Revenue recognition

The Company derives its revenues primarily from subscription services, professional services, perpetual licensing of its software products and associated software maintenance and support services.

The Company determines revenue recognition through the following steps:
Identification of the contract, or contracts, with a customer;
Identification of the performance obligations in the customer contract(s);
Determination of the transaction price;
Allocation of the transaction price to each performance obligation in the customer contract(s); and
Recognition of revenue when, or as, the Company satisfies a performance obligation.

Subscription services revenue

Subscription services primarily include customer access to one or more of the Company's cloud applications and associated customer support. Subscription services revenue is generally recognized ratably over the contractual subscription term, beginning on the date that the Company's subscription service is made available to the customer. The Company's subscription contracts do not provide customers with the right to take possession of the software supporting the service and, as a result, are accounted for as service contracts. The Company's subscription contracts are generally two to five years in length, billed annually in advance, and non-cancelable.

Maintenance and support revenue

Maintenance and support revenue includes post-implementation customer support for on-premise licenses and the right to unspecified software updates and enhancements. The Company recognizes revenue from maintenance and support arrangements ratably over the period in which the services are provided. The Company's maintenance and support contracts are generally one to three years in length, billed annually in advance, and non-cancelable.

License revenue

Licenses to on-premise software provide the customer with a right to use, in the customer's environment, the Company's software as it exists when made available to the customer. License revenue from customer contracts with distinct on-premises licenses is recognized at the point in time when the software is made available to the customer. For customer contracts that contain license and professional services that are not considered distinct, both the license and professional services are determined to be a single performance obligation and the revenue is recognized over time based upon the Company's efforts to satisfy the performance obligation.


Professional services revenue

Professional services revenue primarily consists of fees for deployment and configuration services, as well as training services. Professional services revenues are generally recognized as the services are rendered for time and material contracts, or on a proportional performance basis for fixed fee contracts. The majority of the Company's professional services contracts are on a fixed fee basis. Training revenues are recognized as the services are rendered.

Significant judgment is required in determining whether professional services contained in a customer subscription services contract are capable of being distinct and are separately identifiable in the customer contract. Professional services determined to be distinct are accounted for as a separate performance obligation and revenue is recognized as the services are performed. If the professional services are not determined to be distinct, the professional services and the subscription services are accounted for as a single performance obligation and revenue is recognized over the contractual term of the subscription beginning on the date that subscription services are made available to the customer.

Customer contracts with multiple performance obligations

A portion of the Company's customer contracts contain multiple performance obligations. Significant judgment is required in determining whether multiple performance obligations contained in a single customer contract are capable of being distinct and are separately identifiable. An obligation determined to be distinct is accounted for as a separate performance obligation and revenue for that separate performance obligation is recognized when, or as, the Company satisfies the performance obligation. If obligations are not determined to be distinct, those obligations are accounted for as a single, combined performance obligation. The transaction price is allocated to each performance obligation on a relative standalone selling price basis.

Leases
    
The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and noncurrent operating lease liabilities in the Company's unaudited condensed consolidated balance sheet.

ROU assets represent the Company’s right to use an underlying asset over the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company includes any anticipated lease incentives in the determination of lease liability.

The Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. The Company gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when determining its incremental borrowing rates.

The Company’s lease terms will include options to extend the lease when it is reasonably certain that the Company will exercise that option. Leases with a term of 12 months or less are not recorded on the Company's unaudited condensed consolidated balance sheet. The Company’s lease agreements do not contain any residual value guarantees.

Internal-use software

Costs incurred to develop internal-use software during the development stage are capitalized, stated at cost, and amortized using the straight-line method over the estimated useful lives of the assets. Development stage costs generally include salaries and personnel costs and third-party contractor expenses associated with internal-use software configuration, coding, installation and testing. For the three months ended September 30, 2019 and 2018, the Company capitalized $0.2 million and $1.2 million, respectively, of internal-use software development costs related to cloud-based offerings, and for the nine months ended September 30, 2019 and 2018, the Company capitalized $1.0 million and $3.7 million, respectively, of internal-use software development costs related to cloud-based offerings. Capitalized internal-use software development costs related to cloud-based offerings are amortized using the straight-line method over the useful life of the asset. For the three months ended September 30, 2019 and 2018, the Company amortized $0.8 million and $0.3 million, respectively, and for the nine months ended September 30, 2019 and 2018, the Company amortized $2.0 million and $0.7 million, respectively, of capitalized internal-use software development costs. Capitalized software for internal use is included in property and equipment, net in the unaudited condensed consolidated balance sheets. Amortization of capitalized internal-use software development costs, once it commences, is included in cost of subscription and cost of services revenues in the accompanying unaudited condensed consolidated statements of comprehensive income (loss).

Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes comparison of future cash flows expected to be generated by the asset or group of assets with the associated assets' carrying value. If the carrying value of the asset or group of assets exceeds its expected future cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value. The Company recorded 0 impairment charges during the three and nine months ended September 30, 2019 and 2018.

Noncash share-based compensation

The Company measures all share-based payments to its employees based on the grant date fair value of the awards and recognizes expenses in the Company's unaudited consolidated statement of comprehensive income (loss) on a straight-line basis over the periods during which the recipient is required to perform services (generally over the vesting period of the awards). To date, the Company has granted stock options, Restricted Stock Units ("RSUs"), stock settled Stock Appreciation Rights ("SARs") and Market Stock Units ("MSUs"). RSUs include (i) time-based awards, (ii) performance-based awards in which the number of shares that vest are based upon achievement of certain internal performance metrics set by the Company, and (iii) market-based awards in which the number of shares that vest are based upon attainment of target average per share closing price over a requisite trading period. MSUs are performance-based awards in which the number of shares that vest are based upon the Company's relative stockholder return.

The following table presents the number of shares or units outstanding for each award type as of September 30, 2019 and December 31, 2018, respectively, (in thousands):
Award type September 30, 2019 December 31, 2018
Restricted stock units (time-based) 1,876
 1,969
Restricted stock units (performance-based) 114
 
Restricted stock units (market-based) 
 215
Stock appreciation rights 165
 287
Market stock units 267
 419
Stock options, time-based RSUs and SARs vest ratably between one and 4 years. Performance-based RSUs vest on the third anniversary of the grant and the maximum number of shares issuable upon vesting is 200% of the initially granted shares based upon achievement of certain internal performance metrics set by the Company, as defined by each award's plan documents or individual award agreements. Market-based RSUs vest if the average trailing closing price of the Company's common stock meets certain minimum performance hurdles for at least 105 calendar days prior to September 9, 2020, with 25% vesting at $27, an additional 25% vesting at $33, and the remaining 50% vesting at $41. The actual number of MSUs that will be eligible to vest is based on the total stockholder return of the Company relative to the total stockholder return of the Russell 2000 Index ("Index") over their respective performance periods, as defined by each award's plan documents. The Company did not grant any stock options, SARs or MSUs during the three and nine months ended September 30, 2019 or 2018.

The fair value of the time-based and performance-based RSUs is based on the closing price of the Company's stock on the date of grant.

The Company estimates the fair value and the derived service period of the market-based RSUs on the date of grant using a 'Monte Carlo' simulation model. The model requires the use of a number of assumptions including the expected volatility of the Company's stock, its risk-free interest rate and expected dividends. The Company's expected volatility at the date of grant was based on the historical volatility of the Company over the performance period.

The fair value of the market-based RSUs is expensed over the derived service period for each separate vesting tranche. The derived service period for the vesting tranches of the market-based RSUs ranges between 1.01 and 1.98 years.

The Company estimates the fair value of MSUs on the date of grant using a 'Monte Carlo' simulation model. The determination of fair value of the MSUs is affected by the Company's stock price and a number of assumptions including the expected volatilities of the Company's stock and the Index, its risk-free interest rate and expected dividends. The Company's

expected volatility at the date of grant was based on the historical volatilities of the Company and the Index over the performance period.

Earnings per share

The Company computes basic earnings (loss) per share by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding. Diluted earnings (loss) per share is computed by giving effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible notes using the if-converted method. Dilutive potential common shares consist of shares issuable upon the exercise of stock options, shares of unvested restricted stock units and market stock units, and settlement of stock appreciation rights. When the Company incurs a net loss, the effect of the Company's outstanding stock options, stock appreciation rights, restricted stock units, market stock units and convertible notes are not included in the calculation of diluted earnings (loss) per share as the effect would be anti-dilutive. Accordingly, basic and diluted net loss per share are identical.
Equity investment
Investments in equity securities of privately held companies without readily determinable fair value, where the Company does not exercise significant influence over the investee, are recorded at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee.  Adjustments resulting from impairment, fair value, or observable price changes are accounted for in the unaudited condensed consolidated statements of comprehensive income (loss).

As of September 30, 2019 and December 31, 2018, the Company held $2.2 million and $2.0 million, respectively, of equity securities in a privately held company. This investment is accounted for at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee. The Company estimates fair value of its equity investment considering available information such as pricing in recent rounds of financing, current cash positions, earnings and cash flow forecasts, recent operational performance and any other readily available market data, which represents level 3 in the fair value hierarchy as defined by Accounting Standard Codification ("ASC") 820, "Fair Value Measurement and Disclosure" ("ASC 820"). As of September 30, 2019 and December 31, 2018, the Company determined there were no other-than-temporary impairments on its equity investment.

Trade and other receivables are primarily comprised of trade receivables, net of allowance for doubtful accounts, contract assets and unbilled receivables. The Company records trade accounts receivable for its unconditional rights to consideration arising from the Company's performance under contracts with customers. The Company's standard billing terms are that payment is due upon receipt of invoice, payable generally within thirty to sixty days. The carrying value of such receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value. TheWhen developing its estimate of expected credit losses on trade and other receivables, the Company estimates its allowance for doubtful accounts for specific trade receivable balances based on historical collection trends,considers the ageavailable information relevant to assessing the collectability of outstanding trade receivables, existing economiccash flows, which includes a combination of both internal and external information relating to past events, current conditions, and any financial security associated withfuture forecasts as well as relevant qualitative and quantitative factors that relate to the receivables.environment in which the Company operates.

Contract assets represent conditional rights to consideration that have been recognized as revenue in advance of billing the customer. Unbilled receivables represent unconditional rights to consideration arising from contingent revenue that have been recognized as revenue in advance of billing the customer.

    There are no comparable recent events that provide guidance as to the effect of the spread of COVID-19 as a global pandemic. As a result, the impact of COVID-19 is highly uncertain and subject to change. The Company does not yet know the full extent of the impact from COVID-19 to the Company's business operations or the global economy as a whole; however, the impact could have an adverse effect on the Company's customers and inherently the related receivables.

Deferred costs

Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an

incremental sales commission)commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans that are also tied to the value of customer contracts acquired. Deferred costs were $20.6$18.9 million and $17.5$21.2 million as of September 30, 20192020 and December 31, 2018,2019, respectively. Amortization expense for the deferred costs was $1.5 million and $1.3 million and $0.8 million for the three months ended September 30, 20192020 and 2018,2019, respectively, and $4.3 million and $3.5 million and $2.1 million for the nine months ended September 30, 2020 and 2019, respectively. Amortization of deferred costs is included in selling and 2018, respectively.marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive income (loss).

Deferred implementation costs

The Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), that are associated with arrangements where professional services are not distinct from other undelivered obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs that are directly related to customer contracts, that are expected to be recoverable, and that enhance the resources which will be used to satisfy the undelivered performance obligations in those contracts. Deferred implementation costs are amortized ratably over the remaining contract term once the revenue recognition criteria for the respective performance obligation has been met and revenue recognition commences. Deferred implementation costs were $4.8 $3.2 million and $3.9$4.4 million as of September 30, 20192020 and December 31, 2018,2019, respectively. Amortization expense for the deferred implementation costs was $0.4$0.4 million and $0.1 million for the three months ended September 30, 2020 and 2019 and 2018, respectively, $1.4 million and $1.0 million and $0.4 million for the nine months ended September 30, 20192020 and 2018,2019, respectively. Deferred implementation costs are included in prepaid and other current assets and other assets, noncurrent in the unaudited condensed consolidated balance sheets. Amortization of deferred implementation costs is included in cost of subscription and cost of services revenues in the accompanying unaudited condensed consolidated statements of comprehensive income (loss).

Deferred revenue

Deferred revenue primarily consists of customer invoicing in advance of revenues being recognized. The Company generally invoices its customers annually in advance for subscription services and maintenance and support services. Deferred revenue that is anticipated to be recognized during the next twelve-month period is recorded as current deferred revenue and the remaining portion is recorded as long-term.

Table of September 30, 2019, the Company had 0 outstanding borrowings under its $50.0 million secured Credit Agreement ("Revolver") with the lenders party thereto and Wells Fargo Bank, National Association as agent for the lenders party thereto. The Company included $0.1 million of unamortized debt issuance costs related to the Revolver in prepaid and other current assets and other assets, noncurrent in the unaudited condensed consolidated balance sheets. For the three and nine months ended September 30, 2019 and 2018, the Company recorded an immaterial amount of amortization of debt issuance cost which is included in other income (expense), net in the unaudited condensed consolidated statements of comprehensive income (loss).Contents

Income taxes

The Company recorded an income tax provision of $0.1 million and $0.2 million for the three months ended September 30, 2019 and 2018, respectively, and $0.6 million and $0.2 million for the nine months ended September 30, 2019 and 2018, respectively, primarily related to foreign income taxes and withholding taxes. The effective tax rate was (0.6)% and (1.1)% for the three months ended September 30, 2019 and 2018, respectively, and (1.1)% and (0.3)% for the nine months ended September 30, 2019 and 2018, respectively. The income tax rates vary from the federal and state statutory rates primarily due to the valuation allowances on the Company’s deferred tax assets and foreign and state taxes not based on income. The Company estimates its annual effective tax rate at the end of each quarterly period. Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation allowances on the Company’s deferred tax assets are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.

Recently adopted accounting pronouncements

In FebruaryJune 2016, the FASB issued ASU 2016-02, "2016-13, LeasesFinancial Instruments-Credit Losses (Topic 842)"326): Measurement of Credit Losses on Financial Instruments ("Topic 842"326"), whichin order to improve financial reporting of expected credit losses on financial instruments and other commitments to extend credit. Topic 326 requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the lesseeincurred loss impairment methodology in current GAAP with a methodology that requires consideration of a broader range of information to recognize most leases on the balance sheet thereby resulting in the recognition of right-of-use ("ROU") assets and lease liabilities for those leases currently classified as operating leases. Lessor accounting remains largely unchanged from current guidance, however, Topic 842 provides improvements that are intended to align lessor accounting with the lessee model and with updated revenue recognition guidance. This standard took effect in the first quarter of 2019, including interim periods within that reporting

period.estimate credit losses. The Company adopted Topic 842326 as of January 1, 20192020 using the modified retrospective method by recognizing the cumulative effect of initially applying the new standard as an adjustment to the opening balances of operating ROU assets and lease liabilities, while prior period amounts are not adjusted and continue to be reported in accordance with the Company's historic accounting under the prior lease accounting rules in ASC 840, "Leases".

The Company elected the package of practical expedients permitted under the transition guidance within the new Topic 842 standard for all asset classes, which among other things, allowed the Company to carryforward the historical lease classification. The Company also elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The Company made an accounting policy election to not recognize leases with an initial term of 12 months or less on the balance sheet and instead would recognize those lease payments on a straight-line basis over the lease term in the unaudited condensed consolidated statement of comprehensive income (loss).

The adoption of the standard had a material impact on the Company’s unaudited condensed consolidated balance sheet as a result of the increase of $26.9 million in assets and liabilities from recognition of ROU assets and lease liabilities. The standard did not have a material impact on the Company's unaudited condensed consolidated statement of comprehensive income (loss).

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" ("Subtopic 350-40"). The amendment aligns the requirements for capitalizing implementation costs in a cloud computing arrangement service contract with the requirements for capitalizing implementation costs incurred to develop or obtain an internal-use software. The standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019; early adoption is permitted. The Company early adopted Subtopic 350-40 prospectively effective January 1, 2019 and there was no material impact on the Company's unaudited condensed consolidated financial statements as of the adoption date. In addition, the new standard had no significant impact on the unaudited condensed consolidated financial statements for the three and nine months ended As of September 30, 2019.2020, the Company has recorded allowance for doubtful accounts related to trade receivables of $4.6 million primarily due to increased credit risk from uncertain economic conditions caused by COVID-19.

Recently issued accounting pronouncements not yet adopted

In January 2017,August 2020, the FASB issued ASU 2017-04, "2020-06, IntangiblesDebt - GoodwillDebt with Conversion and Other (Topic 350): Simplifying the Test for Goodwill ImpairmentOptions ("Subtopic 470-20") and Derivatives and Hedging - Contracts in an Entity's Own Equity ("Subtopic 815-40")" ("Topic 350"), which eliminates step two fromsimplifies the goodwill impairment test.

Thethese changes. This new standard is effective for the Company's interim and annual reporting periods beginning after December 15, 2019;January 1, 2022, and earlier adoption is permitted for goodwill impairment tests performed afteron January 1, 2017.2021. The Company may elect to apply the amendments on a retrospective or modified retrospective basis. The Company is currently assessing the impact of Topic 350the adoption of the standard on its unaudited condensed consolidated financial statements.

With the exception of the new standards discussed above, there have been no other recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2019,2020, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.

The Redemption will occur on October 30, 2019, unless earlier converted. Prior to the consummation of the Redemption, the holders of the 2047 Notes are entitled to convert such notes into shares of the Company’s common stock at a rate of 21.2861 shares per $1,000 principal amount of the 2047 Notes, which is equivalent to a conversion price of $46.98 per share.

Note Hedge and Warrant Transactions

Concurrently with the offering of the 2019 Notes, the Company entered into separate convertible note hedge (the "Note Hedge") and warrant (the "Warrant") transactions. Taken together, the purchase of the Note Hedge and the sale of the Warrant arewere intended to offset any actual dilution from the conversion of the 2019 Notes and to effectively increase the overall conversion price of the 2019 Notes from $33.79 to $45.48 per share. The total cost of the Note Hedge transactionWarrant was $29.4 million. The Company received $17.1 million in cash proceeds from the sale of the Warrant. The Warrant is not part of the 2019 Notes or Note Hedge. Both the Note Hedge and Warrant have been accounted forwere recorded as part of additional paid-in capital.
    As of December 31, 2019, the Note Hedge was settled through certain note hedge termination agreements and exercise of any remaining Note Hedge. In May 2019, in connection with the Exchange Transactions, the Company entered into certain note hedge termination agreements (the “Note Hedge Termination Agreements”) and warrant termination agreements (the “Warrant Termination Agreements”). The Company received cash proceeds of $64.8 million related to the Note Hedge Termination Agreements and paid $45.2 million related to the Warrant Termination Agreements. The Note Hedge Termination Agreements terminated certain of the Note Hedges that were entered into by the Company in connection with the offering of the 2019 Notes. The Warrant Termination Agreementswhich terminated certain of the Warrants that were entered into by the Company in connection with the offering of the 2019 Notes. The remaining Warrants expired in August 2020.

Capped Call Transactions

In September 2020 and in May 2019, in connection with the offering of the 2027 and 2024 Notes, respectively, the Company entered into privately negotiated capped call transactions (collectively,(collectively, the "Capped Call") with certain option counterparties. The Capped Call transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the 2024 Notes, at a strike price that corresponds to the initial conversion price of the 2024 Notes, also subject to adjustment, and are exercisable upon conversion of the 2024 Notes. The Capped Call transactions are intended to reduce potential dilution ofto the Company'sCompany’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amountamounts upon any conversion of 2024 Notes, and to effectively increase the overall conversion price of the 2027 Notes from $41.82 to $78.90 per share, and for the 2024 Notes from $66.05 to $101.62 per share. As the Capped Call transactions meet certain accounting criteria, they are recorded in stockholders’ equity and are not accounted for as

The outcomes of these matters are inherently unpredictable. The Company is not currently involved in any outstanding litigation that it believes, individually or in the aggregate, will have a material adverse effect on its business, financial condition, results of operations or cash flows.

Purchase commitments

COVID-19 Impact

    In March 2020, the World Health Organization declared the outbreak of the coronavirus ("COVID-19") a pandemic. COVID-19 continues to spread throughout the world and has resulted in governmental authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders and business limitations and shutdowns. Compliance with these measures by us and by our customers has impacted our business, as well as the businesses of our customers, suppliers and other counterparties, and this impact could last for an indefinite period of time. In particular, in the travel industry, our airline customers are managing historic declines in demand for travel globally. If a significant number of our customers are unable to continue as a going concern, seek to avoid their contracts with us as part of filing for bankruptcy protection, or reduce their purchasing volumes following expiration of their current contracts, this would have an adverse impact on our business and financial condition. There are no comparable recent events that provide guidance as to the effect of the spread of COVID-19 as a global pandemic, and as a result, we are unable to predict the full impact that COVID-19 will have on our results from operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures. For a full discussion on the ongoing impact of COVID-19 to our business, please see "We must successfully navigate the demand, supply and operational challenges associated with the ongoing coronavirus (COVID-19) pandemic" under Part II, Item 1A of this Quarterly Report on Form 10-Q.

Q3 20192020 Financial Overview

In the third quarter of 2019,2020, subscription revenue increased 57%9% and 51%22%, respectively for the three and nine months ended September 30, 2019,2020 as compared to the same periods in 2018. 2019. Our continuing shift to a subscription-based revenue model also led to a growth of recurring revenue (which consists of subscription revenue and maintenance and support revenue) as a percentage of 29% and 26%, respectively,total revenue as compared to the first three and nine months of 2018, andit accounted for 81%86% and 79%, respectively,85% of total revenue for the three and nine months ended September 30, 2020, respectively, as compared to 83% and 81% for the three and nine months ended September 30, 2019. Our total revenue decreased 4% for the three months ended September 30, 2020 as compared to the same period in 2019, and increased 4% for the nine months ended September 30, 2020 as compared to 2019. Revenue in fiscal year 2020 has been impacted by slower customer bookings as a result of decreased demand for new subscriptions and services and delays to projects during the COVID-19 pandemic.

Cash used in operating activities was $61.8 million for the nine months ended September 30, 2020, as compared to $7.6 million for the nine months ended September 30, 2019, as compared to $9.5 million for the nine months ended September 30, 2018.2019. The decreaseincrease in net cash used in operating activities was primarily attributabledriven mainly by an increase in headcount and higher annual incentive payment as compared to changes in working capital partially offsetprior year, deferred payment terms for certain customers impacted by increasedthe pandemic, and the impact of adjustments to net loss primarily driven by loss on debt extinguishment.lower customer bookings as a result of the pandemic.

Free cash flow is another key metric to assess the strength of our business. We define free cash flow, a non-GAAP financial measure, as net cash provided by (used in) operating activities minus capital expenditures (excluding expenditures for our new headquarters), purchases of other (non-acquisition-related) intangible assets and capitalized internal-use software development costs. We believe free cash flow may be useful to investors and other users of our financial information in evaluating the amount of cash generated by our business operations. Free cash flow used during the three months ended September 30, 20192020 was $3.0$15.7 million, compared to free cash flow use of $2.6$3.0 million for the three months ended September 30, 2018.2019. Free cash flow used during the nine months ended September 30, 20192020 was $11.8$64.8 million, compared to $14.6$11.8 million for the nine months ended September 30, 2018.2019. This decreaseincrease was primarily attributable to a $1.9$54.2 million decreaseincrease in net cash used in operating activities primarily duedriven mainly by an increase in headcount and higher annual incentive payment as compared to changes in working capital partially offsetprior year, deferred payment terms for certain customers impacted by increasedthe pandemic, and the impact of adjustments to net loss primarily driven by loss on debt extinguishment. lower customer bookings as a result of the pandemic.

Factors Affecting Our Performance

Key factors and trends that have affected, and we believe will continue to affect, our operating results include:
COVID-19 Global Impact. The global economy has been significantly and negatively impacted by COVID-19, and the scope and duration of the outbreak and timeframe for economic recovery is uncertain. The travel industry, a sector served by our solutions, has been particularly adversely impacted. For example, unprecedented declines in travel demand have forced airlines, including some of our customers, to respond by significantly reducing capacity, grounding flights, reducing personnel, adjusting corporate liquidity and, in certain cases, filing for bankruptcy protection. The global workplace environment has also substantially changed in the wake of COVID-19. To support the health and well-being of our employees, customers, partners and communities, our global workforce has been primarily working remotely since March 16, 2020. In addition, many of our customers are also working primarily remotely, which in some cases has delayed, and may continue to impact the timing of new business and implementations of our solutions. The duration and extent of the impact of COVID-19 continues to be unknown and could continue to impact the pace and timing of adoption and implementation of our solutions, cash flow from operations and customer churn.

Buying Preferences Driving Technology Adoption. Corporate buyers are increasingly demanding the same type of digital buying experience that they enjoy as consumers. For example, buyers increasingly prefer to buy online when they have already decided what to buy, and often prefer not to interact with a sales representative as their primary source of research. In response, we believe that businesses are increasingly looking to modernize their sales process to compete in digital commerce by adopting technologies which provide fast, frictionless, and personalized buying experiences across sales channels. We believe we are uniquely positioned to help power these buying experiences with our AI-powered solutions that enable buyers to move fluidly across our customers’ direct sales, online, mobile and partner channels and have personalized experiences however they choose to buy. 
COVID-19 Financial Impact. As compared to our expectations prior to COVID-19, the global economic impact of COVID-19 adversely impacted our revenue, bad debt expense and operating cash flow during the three and nine months ended September 30, 2020. We expect customer bookings and the related revenue and cash flows will continue to be lower than anticipated prior to the pandemic as a result of decreased demand for new subscriptions and services and delays to projects during the COVID-19 pandemic. In addition, certain customers have requested, and we expect will continue to request, relief to existing contracts and the impact of those is uncertain. For example, some customers and prospective customers are delaying projects while they address immediate financial difficulties in their operations, renegotiating existing contracts, and in limited cases filing for bankruptcy protection. Based on demand for their own products and services being down due to COVID-19, some of our customers, particularly those in the travel industry, may renew their subscriptions for our solutions at lower capacity levels for a lower annual fee. The impact on our revenue due to such reduced renewals, combined with other customer actions described in this paragraph, is uncertain.

Buying Preferences Driving Technology Adoption. Corporate buyers are increasingly demanding the same type of digital buying experience that they enjoy as consumers. For example, buyers often prefer not to interact with a sales representative as their primary source of research, and increasingly prefer to buy online when they have already decided what to buy, particularly during the current pandemic environment. In response, we believe that businesses are increasingly modernizing their sales process to compete in digital commerce by adopting technologies which provide

fast, frictionless, and personalized buying experiences across sales channels. We believe we are uniquely positioned to help power these buying experiences with our AI-powered solutions that enable buyers to move fluidly across our customers’ direct sales, online, mobile and partner channels and have personalized experiences however they choose to buy.

Continued Investments. In light of COVID-19, we are continuing to be measured in our investments and focused on cost control efforts across our organization, while continuing to create awareness for our solutions, expand our customer base and grow our recurring revenues. While we incurred losses in the first nine months of 2020, we believe our market is large and underpenetrated and therefore we intend to continue investing in sales, marketing, customer success, cloud support, security, privacy, infrastructure and other long-term initiatives to expand our ability to sell and renew our subscription offerings globally. We also plan to continue investing in product development to enhance our existing technologies, including initiatives to accelerate customer time-to-value and provide out-of-the-box integration with third-party commerce solutions, and develop new applications and technologies. In reaction to the COVID-19 environment, we have slowed our overall rate of hiring while continuing to hire for certain strategic positions and have transferred personnel within the company and redeployed other resources to focus on current priorities.

Cloud Migrations. Sales of our cloud-based solutions have, and we expect future sales of our cloud-based solutions will continue to reduce our future maintenance and support revenue, as existing customers migrate from our licensed solutions to our cloud solutions.

Sales Mix Impacts Subscription Revenue Recognition Timing. The mix of subscription services and professional services can create revenue variability in given periods based on the nature and scope of services sold together. Professional services that are deemed to be distinct from the subscription services are accounted for as a separate performance obligation and revenue is recognized as the services are performed. If determined the professional services are not considered distinct, the professional services and the subscription services are considered to be a single performance obligation and all revenue is recognized over the contractual term of the subscription beginning on the date subscription services are made available to the customer, resulting in a deferral of revenue and revenue recognized over a shorter period of time, which would have a negative near-term financial impact.

Continued Investments. We are focused on creating awareness for our solutions, expanding our customer base and growing our recurring revenues. While we incurred losses in the nine months of 2019, we believe our market is large and underpenetrated and therefore we intend to continue investing to expand our ability to sell and renew our subscription offerings globally through investments in sales, marketing, customer success, cloud support, security, privacy, infrastructure and other long-term initiatives. We also plan to continue to invest in product development to enhance our existing technologies and develop new applications and technologies.

Cloud Migrations. We expect that over time, additional sales of our cloud-based solutions will result in a decrease in our maintenance and support revenue, particularly as existing customers continue to migrate from our licensed solutions to our cloud solutions.

Sales Mix Impacts Subscription Revenue Recognition Timing. The mix of subscription services and professional services can create revenue variability in given periods based on the nature and scope of services sold together. Professional services that are deemed to be distinct from the subscription services are accounted for as a separate performance obligation and revenue is recognized as the services are performed. If determined that the professional services are not considered distinct, the professional services and the subscription services are determined to be a single performance obligation and all revenue is recognized over the contractual term of the subscription beginning on the date that subscription services are made available to the customer, resulting in a deferral of revenue and revenue recognized over a shorter period of time, which would have a negative near-term financial impact.

Subscription revenue. Subscription revenue forincreased primarily due to an increased number of customer subscription contracts as compared to the prior year. For the three and nine months ended September 30, 2019 and 2018 increased primarily due to2020, our subscription revenue growth was negatively impacted by an increase in the number and size of customer subscriptions as comparedchurn mainly due to the prior year. We continued to invest in customer programs and initiatives which helped keep our customer attrition rates fairly consistent as compared to the prior year.impact of COVID-19. Our ability to maintain consistent customer attrition rates will directly impact our ability to continue to grow our subscription revenue. Due to the uncertain economic conditions caused by COVID-19, we expect subscription revenue to grow at a slower pace.

We expect maintenance revenue to continue to decline over time as we sell fewer licenses and related maintenance and support, sell more subscription services and migrate existing maintenance customers to our cloud solutions.

License revenue. License revenue remained relatively unchanged during the three months ended September 30, 2019. License revenue increased during the nine months ended September 30, 2019 primarily due to an increase in license revenue with existing customers recognized upon software delivery.

Services revenue.

Services revenue varies from period to period depending on different factors, including the level of professional services required to implement our solutions, the timing of services revenue recognition on certain subscription contracts and any additional professional services requested by our customers during a particular period. Due to the uncertain economic conditions caused by COVID-19, we expect a decline in services revenue.

Income tax provision. The tax provision for the three and nine months ended September 30, 20192020 included both foreign income and withholding taxes. No tax benefit was recognized on jurisdictions with a projected loss for the year due to the valuation allowances on our deferred tax assets.

Our effective tax rate was (1.7)% and (1.0)% for the three and nine months ended September 30, 2020, respectively, and (0.6)% and (1.1)% for the three months ended September 30, 2019 and 2018, respectively. Our effective tax rate was (1.1)% and (0.3)% for the nine months ended September 30, 2019, and 2018, respectively. The income tax rate varies from the 21% federal statutory rate primarily due to the valuation allowances on our deferred tax assets and foreign and state taxes not based on income.assets. While our expected tax rate would be 0% due to the full valuation on the deferred tax assets, the (1.7)% and (1.0)% for the three and nine months ended September 30, 2020, respectively, and (0.6)% and (1.1)% tax rate for the three months ended September 30, 2019 and 2018, respectively, and the (1.1)% and (0.3)% for the nine months ended September 30, 2019, and 2018, respectively, is due to foreign income taxes and state taxes not based on pre-tax income.

Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation allowances on our deferred tax assets are excluded from the estimated annual federal effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.

We continue to monitor for tax developments and new legislation and regulation in each of the jurisdictions we operate in. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in the United States on March 27, 2020. The CARES Act did not have a material impact on our provision for income taxes for the three and nine months ended September 30, 2020.

Liquidity and Capital Resources

At September 30, 2019,2020, we had $319.2$322.4 million of cash and cash equivalents and $174.5$245.6 million of working capital as compared to $295.5$306.1 million of cash and cash equivalents and $71.4$189.8 million of working capital at December 31, 2018.2019.

Our principal sources of liquidity are our cash and cash equivalents, cash flows generated from operations and potential borrowings under our Revolver$50 million secured Credit Agreement ("Revolver") with the lenders party thereto and Wells Fargo Bank, National Association as agent for the lenders party thereto.The facility expires in July 2022. We issued the 20192027 Notes in December 2014, the 2047 Notes in June 2017, the Secondary Offering in August 2018September 2020 and the 2024 Notes in May 2019 to supplement our overall liquidity position. Our material drivers or variants of operating cash flow are net income (loss), noncash expenses (principally share-based compensation, intangible amortization and amortization of debt discount and issuance costs) and the timing of periodic invoicing and cash collections related to licenses, subscriptions and support for our software and related services. Our operating cash flows are also impacted by the timing of payments to our vendors, and the payments of our other liabilities.liabilities and customer concessions. We generally pay our vendors and service providers in accordance with the invoice terms and conditions.

We believe our existing cash, cash equivalents, including funds available under our Revolver and our current estimates of future operating cash flows, will provide adequate liquidity and capital resources to meet our operational requirements, anticipated capital expenditures and coupon interest payments for our Notes for the next twelve months. Our future working capital requirements will depend on many factors, including the operations of our existing business, potential growth of our subscription services, future acquisitions we might undertake, and expansion into complementary businesses.businesses, and the impact of COVID-19, including the pace and timing of adoption and implementation of our solutions, relief to existing contracts and customer churn. If such need arises, we may raise additional funds through equity or debt financings. However, the recent COVID-19 pandemic caused some disruption in the capital markets and further disruption could make financing more difficult and/or expensive and we may not be able to obtain such financing on terms acceptable to us or at all. During the period of uncertainty and volatility related to COVID-19, we will continue to monitor our liquidity.

The $1.9$54.2 million decreaseincrease in cash used as compared to 20182019 was primarily attributable to changeshigher cash operating expenses driven mainly by an increase in working capital partially offset by increasedheadcount and higher annual incentive payment as compared to prior year, customer requests to defer payments to the fourth quarter of fiscal year 2020 and early 2021 and the impact of adjustments to net loss primarily driven by loss on debt extinguishment.lower customer bookings as a result of the pandemic.


Investing Activities

Net cash used in investing activities for the nine months ended September 30, 20192020 was $15.1$24.9 million, which was primarily related to the consideration paid for the acquisition of Travelaer of $10.5 million, capital expenditures of $3.4$23.6 million $1.0mainly attributable to the build out of our new headquarters which was committed prior to the pandemic, $1.3 million related to capitalized internal-use software development costs on our subscription service solutions and an$0.1 million investment in equity securities of $0.2 million.securities.

Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 20192020 was $46.8$103.4 million, which was attributable to proceeds from the issuance of 2024the 2027 Notes of $140.2 million, proceeds from bond hedge termination of $64.8$146.9 million and proceeds from employee stock plans of $2.0$2.8 million, partially offset by the purchase of a cash convertible debt settlement paymentcapped call of $76.0$25.3 million, $45.2 million paid for termination of warrant, $21.6$20.3 million paid for tax withholdings on vesting of employee share-based awards purchase of capped call of $16.4 million, and payment for convertible debt issuance cost of $0.9$0.7 million.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material. We do not have any relationships with unconsolidated entities or financial partnerships, such as variable interest entities, that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Contractual Obligations and Commitments

Other than changes described in Note 10 above, there have been no material changes to our contractual obligations and commitments disclosed in our Annual Report.

Credit facility

There were no outstanding borrowings under the Revolver as of September 30, 2019.2020. As of September 30, 2019,2020, we had $0.1 million of unamortized debt issuance costs related to the Revolver included in prepaids and other current assets and other long-term assets in the unaudited condensed consolidated balance sheets. For the three and nine months ended September 30, 20192020 and 2018,2019, we recorded an immaterial amount of amortization of debt issuance cost which is included in other expense, net in the unaudited condensed consolidated statements of comprehensive income (loss).

Critical accounting policies and estimates

Our consolidated financial statements are prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures. Actual results could differ from those estimates. The complexity and judgment required in our estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in determining the nature and timing of satisfaction of performance obligations and determining the standalone selling price of performance obligations, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for doubtful accounts, operating lease right-of-use assets and operating lease liabilities, useful lives of assets, depreciation, income taxes and deferred tax asset valuation, valuation of stock options, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. Our critical accounting policies related to the estimates and judgments are discussed in our Annual Report under management's discussion and analysis of financial condition and results of operations, except for the leases policy which has been updated in resultoperations.

Table of the adoption of the new lease standard under Topic 842 and is included herein.Contents

Leases

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and noncurrent operating lease liabilities in the unaudited condensed consolidated balance sheet.

ROU assets represent our right to use an underlying asset over the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We include any anticipated lease incentives in the determination of lease liability.

We use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. We give consideration to our recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates.
Our lease terms include options to extend the lease when it is reasonably certain that we will exercise that option. Leases with a term of 12 months or less are not recorded on the unaudited condensed consolidated balance sheet. Our lease agreements do not contain any residual value guarantees.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

Although our contracts are predominately denominated in U.S. dollars, we are exposed to foreign currency exchange risk because we also have some contracts denominated in foreign currencies. The effect of a hypothetical 10% adverse change in exchange rates on our foreign denominated receivables as of September 30, 20192020 would result in a loss of approximately $0.3 $0.5 million. WeWe are also exposed to foreign currency risk due to our operating subsidiaries in France, United Kingdom, Canada, Germany, Ireland, Australia, Bulgaria and United Arab Emirates. A hypothetical 10% adverse change in the value of the U.S. dollar in relation to the euro, which is our single most significant foreign currency exposure, would have decreased revenue for the three and nine months ended September 30, 20192020 by approximately $0.2$0.4 million and $0.7$1.2 million, respectively. However,However, due to the relatively low volume of payments made and received through our foreign subsidiaries, we do not believe that we have significant exposure to foreign currency exchange risks. Fluctuations in foreign currency exchange rates could harm our financial results in the future.

We currently do not use derivative financial instruments to mitigate foreign currency exchange risks. We continue to review this matter and may consider hedging certain foreign exchange risks through the use of currency futures or optionsderivatives in future years.

Interest Rate Risk

We are exposed to market risk for changes in interest rates related to the variable interest rate on borrowings under the Revolver. As of September 30, 2019,2020, we had no borrowings under the Revolver.


As of September 30, 2019,2020, we had outstanding principal amounts of $21.6$150.0 million and $143.8 million and $24.1 million respectively, of the 2019 Notes,2027 and the 2024 Notes, and the 2047 Notesrespectively, which are fixed rate instruments. Therefore, our results of operations are not subject to fluctuations in interest rates. The fair value of the Notes may change when the market price of our stock fluctuates.

We believe that we do not have any material exposure to changes in the fair value as a result of changes in interest rates due to the short term nature of our cash equivalents.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act) as of September 30, 2019.2020. Based on our evaluation of our disclosure controls and procedures as of September 30, 2019,2020, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

In August 2019, we acquired Travelaer, in an all-cash transaction. See Note 5, "Business Combinations" to the unaudited interim consolidated financial statements included in this Quarterly Report on Form 10-Q for a discussion of this acquisition and related financial data. Management has considered this acquisition immaterial to the results of operations, cash flows and financial position from the date of the acquisition through September 30, 2019. In accordance with SEC guidance, management plans to exclude Travelaer from management’s assessment of, and report on, internal controls over financial reporting from the date of the acquisition through December 31, 2019. We are in the process of reviewing the operations of Travelaer and evaluating the impact of the acquisition on our internal controls over financial reporting. Excluding this acquisition, there    There have been no changes in our internal control over financial reporting during the three months ended September 30, 20192020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that our employees are working remotely due to COVID-19. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

    We implemented internal controls to ensure we adequately evaluated our lease contracts and properly assessedprovisions for credit losses in light of the impact of our adoption of Topic 842326 on January 1, 2019.2020. There were no significant changes to our internal control over financial reporting due to the adoption of Topic 842.326.

PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS

From time to time, we are a party to legal proceedings and claims arising in the ordinary course of business. We are not currently aware of any such proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition, results of operations or cash flows.

ITEM 1A. RISK FACTORS

There have been no material changes in the Company's risk factors from those disclosed in Part I, Item 1A, of our Annual Report with the exception of the following revisedrisk factors:

    We must successfully navigate the demand, supply and updated risk factor.operational challenges associated with the ongoing coronavirus (COVID-19) pandemic.

The ongoing global COVID-19 pandemic has adversely impacted, and may continue to adversely impact, many aspects of our business. As COVID-19 has continued to spread throughout the world, a number of governmental authorities have implemented or reinstated numerous severe measures in an attempt to contain the spread of COVID-19, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. Compliance with these measures by us and by our prospects and customers has impacted our business, as well as the businesses of our customers, prospects, suppliers and other counterparties, and this impact could last for an indefinite period of time. For example, in the travel industry, our airline customers are experiencing unprecedented declines in demand for travel globally, airline travel demand may remain suppressed until a widely accepted treatment and/or vaccine for COVID-19 is available, and recovery in airline travel demand from COVID-19 may not follow a linear path. The economic impact of COVID-19 has also adversely impacted a number of our prospects and customers, who have experienced, and may continue to experience, downturns or uncertainty in their own businesses. In response, some prospects and customers, particularly those in the travel industry, have decreased, and may continue to decrease, spending on technology initiatives, as well as stalled or halted implementation projects while they address their immediate financial difficulties, including in limited cases through filing for bankruptcy protection. In addition, certain customers have requested, and we expect will continue to request, concessions from existing contracts, and the extent and impact of future requests is uncertain. If a significant number of our customers are unable to make their contractually obligated payments to us, elect to file for bankruptcy protection, or otherwise choose to renew their current contracts for our solutions at lower usage levels, this would have an adverse impact on our business and financial condition.The impact on our revenue due to such reduced renewals, combined with other customer actions described in this paragraph, is uncertain.

As compared to our expectations prior to COVID-19, the global economic impact of COVID-19 adversely impacted our revenue, bad debt expense and operating cash flow during the three and nine months ended September 30, 2020. We expect that customer bookings and the related revenue and cash flows will continue to be lower than anticipated prior to the pandemic as a result of decreased demand for new subscriptions and services and delays to projects during the pandemic. In particular, new demand for our airline solutions has been limited during COVID-19, and we expect that new demand for our airline solutions will continue to be limited in the near term. In response, we have postponed or canceled, and may continue to postpone or cancel, planned investments in our business, which may impact our product development and rate of innovation, either of which could seriously harm our business. However, as there are no comparable recent events that provide guidance as to the effect of the spread of COVID-19, the resultant personal, economic and governmental reactions, or the extent and duration of the pandemic and containment measures, we are unable to forecast the full impact that COVID-19 will have on our bookings, revenue, results from operations, financial condition, liquidity and cash flows, and may have to take additional actions in the future that could further harm our business and financial performance. Although we expect that current cash and cash equivalent balances and cash flows that are generated from operations will be sufficient to meet our working capital needs and other capital and liquidity requirements for at least the next 12 months, if our access to capital is restricted or our borrowing costs increase, our operations and financial condition could be adversely impacted.

To support the health and well-being of our employees, customers, partners and communities, we implemented and expect to continue a work-from-home policy for substantially all our employees and materially limited business travel, and we may take further actions that alter our operations as may be required by federal, state, or local authorities, or which we determine are in our best interests. While almost all of our operations have been performed remotely since March 2020, and we have not experienced any material interruptions to our operations to date, there is no guarantee that we will continue to be as effective while working remotely. The disruptions caused by COVID-19, including the limitations on meeting in-person with existing and potential customers and amongst our teams because our team is dispersed, may result in inefficiencies, delays and additional costs in our product development, sales, marketing, product implementations and customer service efforts that we
28

Table of Contents
cannot fully mitigate through remote work arrangements. Many employees have additional personal needs to attend to (such as looking after children as a result of school closures or delays to school calendars or family who becomes sick), and employees may continue to become sick themselves and be unable to work. If one or more of our executives or senior leaders were to become sick and/or hospitalized with COVID-19, it could have a significant impact on our operations. In addition, work-from-home and related business practice modifications could present challenges to maintaining our corporate culture, including employee engagement, development and productivity, both during the ongoing pandemic and as we make additional adjustments to transition from it. As local regulations permit, we expect to provide limited access to our offices for our employees, and when appropriate, we anticipate that we will fully reopen our offices. Planning for the re-opening of our offices has required and will likely continue to require non-trivial investments to manage additional risks and operational challenges, including in the design, implementation and enforcement of new workplace safety protocols. These efforts may divert management attention, and the protocols may create logistical challenges for our employees which could adversely impact employee productivity and morale. Even if we follow what we believe to be best practices, there can be no assurance that our measures will prevent the transmission of COVID-19 between employees. Any incidents of actual or perceived transmission may expose us to liability from employee claims, adversely impact employee productivity and morale, and even result in negative publicity and reputational harm.

The impacts of COVID-19 on our business, customers, partners, employees, markets and financial results and condition continue to be uncertain, evolving, dynamic and dependent on numerous unpredictable factors outside of our control, including:

the spread, duration and severity of COVID-19 as a public health matter and its impact on governments, businesses and society generally and our clients, partners and our business;

the mitigation, treatment and other related measures being taken by governments, businesses and society in response to COVID-19 and the effectiveness of those measures;

the scope and effectiveness of fiscal and monetary stimulus programs and other legislative and regulatory measures being implemented by federal, state and local governments in response to COVID-19;

the duration and impact of the numerous measures implemented by governmental authorities throughout the United States and internationally to contain COVID-19, including travel bans and restrictions, quarantines, shelter-in-place orders and business limitations and shutdowns;

the impact of COVID-19 on overall long-term demand for air travel, including the impact on overall demand for business travel as a result of increased usage of teleconferencing and other technologies;

the impact of COVID-19 on the financial health and operations of our current and prospective customers and partners, including the increase in business failures among our customers and other businesses;

the pace and extent to which our customers and other businesses reduce their number of employees and other compensated individuals;

the possibility of failure of our operating facilities, computer systems or communication systems during a catastrophic event, including COVID-19;

the willingness of current and prospective clients to invest in our products and services;

the willingness of current and prospective clients to buy and install products and services remotely; and

the satisfaction of customers with product and service remote delivery and support.

If we are not able to respond to and manage the impact of such events effectively, our results of operations, financial performance, and overall business will be harmed.

More generally, COVID-19 is causing an extended global economic downturn and has caused volatility in financial markets, which has affected, and likely will continue to affect, demand for our products and services and has impacted our results and financial condition. The impact of COVID-19 will likely continue even after the pandemic is contained, vaccines or other widely accepted treatments become available and the containment measures are lifted. For example, airline travel demand may remain suppressed until a widely accepted treatment and/or vaccine for COVID-19 is available, and recovery in airline

travel demand from COVID-19 may not follow a linear path. In addition, we may be unable to collect receivables from or renew subscription agreements with those customers significantly impacted by COVID-19. Similarly, a decrease in bookings in a given period could negatively affect our revenues in future periods, particularly if experienced on a sustained basis, because our subscription revenue is recognized over time. COVID-19 may also have the effect of heightening many of the other risks described in the “Risk Factors” section of our Annual Report on Form 10-K, including risks associated with our customers and supply chain. We will continue to evaluate the nature and extent of the impact of COVID-19 to our business.

We incurred indebtedness by issuing convertible notes, and our debt repayment obligations may adversely affect our financial condition and cash flows from operations in the future.

In September 2020, we issued $150.0 million principal amount of 2.25% convertible senior notes (“2027 Notes”) due September 15, 2027, unless earlier redeemed, purchased or converted in accordance with their terms prior to such date. Interest is payable semi-annually in arrears on March 15 and September 15 of each year. As of September 30, 2020, the entire $150.0 million of aggregate principal amount of 2027 Notes are outstanding.

In May 2019, we issued $143.8 million principal amount of 1.0% convertible senior notes (“2024 Notes”) due May 15, 2024, unless earlier redeemed, purchased or converted in accordance with their terms prior to such date. Interest is payable semi-annually in arrears on May 15 and November 15 of each year. As of September 30, 2019,2020, the entire $143.8 million of aggregate principal amount of 2024 Notes are outstanding.
In June 2017, we issued $106.3 million principal amount of 2.0% convertible senior notes ("2047 Notes") due June 1, 2047, unless earlier redeemed, purchased or converted in accordance with their terms prior to such date. Interest is payable semi-annually in arrears on June 1 and December 1 of each year. In 2019, we issued a notice of redemption and subsequently converted and extinguished a portion of the 2047 Notes. As of September 30, 2019, $24.1 million of aggregate principal amount of 2047 Notes are outstanding.
In December 2014, we issued $143.8 million principal amount of 2.0% convertible senior notes ("2019 Notes") due December 1, 2019, unless earlier purchased or converted. Interest is payable semi-annually in arrears on June 1 and December 1 of each year. We retired a portion of the 2019 Notes in 2019. As of September 30, 2019, $21.6 million of aggregate principal amount of 2019 Notes are outstanding.
Our indebtedness could have important consequences because it may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions and general corporate or other purposes, and a portion of our cash flows from operations may have to be dedicated to repaying the principal beginning in 2019.purposes. Our ability to meet our debt obligations will depend on our future performance, which will be affected by financial, business, economic, regulatory and other factors. We cannot control many of these factors. Our future operations may not generate sufficient cash to enable us to repay our debt. If we fail to comply with any covenants contained in the agreements governing any of our debt, or make a payment on any of our debt when due, we could be in default on such debt.debt, which could, in turn, result in such debt and our other indebtedness becoming immediately payable in full. If we are at any time unable to pay our indebtedness when due, we may be required to renegotiate the terms of the indebtedness, seek to refinance all or a portion of the indebtedness, and/or obtain additional financing. There can be no assurance that, in the future, we will be able to successfully renegotiate such terms, that any such refinancing would be possible or that any additional financing could be obtained on terms that are favorable or acceptable to us.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

We have an ongoing authorization from our board of directors to repurchase up to $15.0 million in shares of our common stock in the open market or through privately negotiated transactions. As of September 30, 2019,2020, $10.0 million remained available for repurchase under the existing repurchase authorization. We did not make any purchases of our common stock under this program for the three months ended September 30, 2019.2020.
