CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended ("Exchange Act"). All statements in this report other than historical facts are forward-looking and are based on current estimates, assumptions, trends, and projections. Statements which include the words "believes," "seeks," "expects," "may," "should," "intends," "likely," "targets," "plans," "anticipates," "estimates," or the negative version of those words and similar expressions are intended to identify forward-looking statements. Numerous important factors, risks and uncertainties affect our operating results, including, without limitation, those described in our Annual Report on Form 10-K and in this Quarterly Report on Form 10-Q, and could cause our actual results to differ materially, from the results implied by these or any other forward-looking statements made by us or on our behalf. You should pay particular attention to the important risk factors and cautionary statements described in the section of our Annual Report on Form 10-K entitled "Risk Factors" and the section of this Quarterly Report on Form 10-Q entitled "Risk Factors." You should also carefully review the cautionary statements described in the other documents we file with the Securities and Exchange Commission, specifically the Annual Report on Form 10-K, all Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
You should not rely on forward-looking statements as predictions of future events, as we cannot guarantee that future results, levels of activity, performance or achievements will meet expectations. The forward-looking statements made herein are only made as of the date hereof, and we undertake no obligation to publicly update such forward-looking statements for any reason.

2. Summary of Significant Accounting Policies
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 June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019, cash flows for the six months ended June 30, 2020 and 2019, and stockholders' equity for the three and six months ended June 30, 2020 and 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, 2019 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2019 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 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 c ompliance 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 a s 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
There have been no material changes in the Company’s significant accounting policies and their application as compared to the significant accounting policies described in 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.

Table of Contents
Fair value measurement
The Company's financial assets that are included in cash and cash equivalents and that are measured at fair value on a recurring basis consisted of $209.2 million and $273.1 million at June 30, 2020 and December 31, 2019, respectively, and were invested in treasury money market funds. The fair value of the treasury money market funds is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by ASC 820.
Trade and other receivables
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. When developing its estimate of expected credit losses on trade and other receivables, the Company considers the available information relevant to assessing the collectability of cash flows, which includes a combination of both internal and external information relating to past events, current conditions, and future forecasts as well as relevant qualitative and quantitative factors that relate to the 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), 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 $19.6 million and $21.2 million as of June 30, 2020 and December 31, 2019, respectively. Amortization expense for the deferred costs was $1.4 million and $1.1 million for the three months ended June 30, 2020 and 2019, respectively, and $2.9 million and $2.2 million for the six months ended June 30, 2020 and 2019, respectively.
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 $3.5 million and $4.4 million as of June 30, 2020 and December 31, 2019, respectively. Amortization expense for the deferred implementation costs was $0.6 million and $0.4 million for the three months ended June 30, 2020 and 2019, respectively, and $1.0 million and $0.6 million for the six months ended June 30, 2020 and 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).

Recently adopted accounting pronouncements
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("Topic 326"), in 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 incurred loss impairment methodology in current GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The Company adopted Topic 326 as of January 1, 2020 using the modified retrospective method and there was no material impact on the Company's unaudited condensed consolidated financial statements as of the adoption date. The Company recognized a $2.4 million expense related to the provision for credit losses in the first half of 2020 representing the Company’s estimate of additional allowance for doubtful accounts related to trade receivables due to increased credit risk from uncertain economic conditions caused by COVID-19. The Company also recorded a write-off of a portion of the allowance of doubtful accounts related to the increased credit risks of $0.5 million during the three months ended June 30, 2020.
Recently issued accounting pronouncements not yet adopted
With the exception of the new standards discussed above, there have been no other recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 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.

For the three months ended June 30, 2020 and 2019, the Company recognized approximately $48.8 million and $43.7 million, respectively, and for the six months ended June 30, 2020 and 2019, the Company recognized approximately $84.0 million and $67.1 million, respectively, in each case of revenue that was included in the deferred revenue balances at the beginning of the respective periods and primarily related to subscription services, maintenance and support, and services.
Performance Obligations
As of June 30, 2020, the Company expects to recognize approximately $374.5 million of revenue from remaining performance obligations. The Company expects, based on the terms of the related, underlying contractual arrangements, to recognize revenue on approximately $180.8 million of these performance obligations over the next 12 months, with the balance recognized thereafter. However, as a result of uncertain economic conditions caused by COVID-19, the amount of revenue recognized from the Company's contractual remaining performance obligations could vary and be less than what the Company expects as revenue recognized could be delayed or not occur depending on the ongoing impact of COVID-19.
4. Disaggregation of Revenue
Revenue by Geography
The geographic information in the table below is presented for the three and six months ended June 30, 2020 and 2019. The Company categorizes geographic revenues based on the location of the customer's headquarters. Because the Company's contracts are predominately denominated in U.S. dollars, it has limited exposure to foreign currency exchange risk as discussed under "Foreign Currency Exchange Risk" of Part I, Item 3 below.

5. Leases
The Company has operating leases for data centers, computer infrastructure, corporate offices and certain equipment. These leases have remaining lease terms ranging from 1 year to 13 years. Some of these leases include options to extend for up to 15 years, and some include options to terminate within 1 year.
In February 2020, the Company entered into an agreement with a computer infrastructure vendor which resulted in future consideration to be paid by the Company for services provided. The Company accounted for this agreement as an operating lease and as a result obtained a $1.5 million right-of-use asset in exchange for a new lease liability of the same amount at lease inception.
As of June 30, 2020, the Company did not have any finance leases.

7. Noncash Share-based Compensation
The Company's 2017 Equity Incentive Plan (as amended and restated, the "2017 Stock Plan") was approved by stockholders in May 2017 and reserved an aggregate amount of 2,500,000 shares for issuance. In May 2019, the shareholders approved an amendment to the 2017 Stock Plan which increased the aggregate amount of shares for issuance to a total of 4,550,000. As of June 30, 2020, 1,857,201 shares remain available for issuance under the 2017 Stock Plan.
The following table presents the number of shares or units outstanding for each award type as of June 30, 2020 and December 31, 2019, respectively, (in thousands):

8. Convertible Senior Notes
The following is a summary of the Company's convertible senior notes as of June 30, 2020 (in thousands):

| Date of Issuance |  | Unpaid Principal Balance |  | Net Carrying Amount |  |  |  | Contractual Interest Rates
|  |  |  |  | Current |  | Noncurrent |  |
1% Convertible Notes due in 2024 ("2024 Notes") | May 2019 |  | $ | 143,750 |  |  | $ | — |  |  | $ | 114,131 |  |  | 1%

The 2024 Notes, along with the previously issued convertible notes with original due dates in 2019 and 2047 (the "2019 Notes" and "2047 Notes," and together with the 2024 Notes, collectively, the "Notes"), are general unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated, are effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries (including trade payables but excluding intercompany obligations owed to the Company or its subsidiaries). The 2019 Notes and 2047 Notes were settled as of December 31, 2019 and no longer remain outstanding.
Interest related to the 2024 Notes is payable semi-annually in arrears on May 15 and November 15 of each year, commencing on November 15, 2019. The 2024 Notes mature on May 15, 2024, unless redeemed or converted in accordance with their terms prior to such date.
Each $1,000 of principal of the 2024 Notes will initially be convertible into 15.1394 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $66.05 per share. The initial conversion price for the 2024 Notes is subject to adjustment upon the occurrence of certain specified events.
As of June 30, 2020, the 2024 Notes are not yet convertible and their remaining term is approximately 46 months.
As of June 30, 2020 and December 31, 2019, the fair value of the principal amount of the 2024 Notes was $138.1 million and $163.2 million, respectively. The estimated fair value was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the Company's stock price and interest rates, which represents level 2 in the fair value hierarchy.
In accounting for the transaction costs for the 2024 Notes issuance, the Company allocated the costs incurred to the liability and equity components in proportion to the allocation of the proceeds from issuance to the liability and equity components. Issuance costs attributable to the liability component, totaling $3.4 million for the 2024 Notes are being amortized to expense over the expected life of the notes using the effective interest method. Issuance costs attributable to the equity component related to the conversion option, totaling $1.1 million for the 2024 Notes were netted with the equity component in stockholders' equity.
The 2024 Notes consist of the following (in thousands):

| June 30, 2020 |  | December 31, 2019
Liability component: |  |  |
Principal | $ | 143,750 |  |  | $ | 143,750 |
Less: debt discount and issuance cost, net of amortization | (29,619) |  |  | (33,046) |
Net carrying amount | $ | 114,131 |  |  | $ | 110,704 |
Equity component(1) | $ | 32,883 |  |  | $ | 32,883 |

(1) Recorded within additional paid-in capital in the unaudited condensed consolidated balance sheet. As of June 30, 2020 and December 31, 2019, it included $32.9 million related to the 2024 Notes, which was net of $1.1 million issuance cost in equity.

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 were 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 Warrant was not part of the 2019 Notes or Note Hedge. Both the Note Hedge and Warrant were 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 2019, the Company entered into certain warrant termination agreements which terminated certain of the Warrants that were entered into by the Company in connection with the offering of the 2019 Notes. The remaining Warrants expire in August 2020 and, if exercised, will settle on a net share basis.
Capped Call Transactions
In May 2019, in connection with the offering of the 2024 Notes, the Company entered into privately negotiated capped call transactions (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 of the Company's common stock and/or offset any cash payments the Company will be required to make in excess of the principal amount upon any conversion of 2024 Notes, and to effectively increase the overall conversion price of 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 derivatives. The cost of the Capped Call was $16.4 million and was recorded as part of additional paid-in capital.
9. Commitments and Contingencies
Litigation
In the ordinary course of business, the Company regularly becomes involved in contract and other negotiations and, in more limited circumstances, becomes involved in legal proceedings, claims and litigation. 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
In the ordinary course of business, the Company enters into various purchase commitments for goods and services.
In March 2019, the Company entered into a noncancelable agreement with a computing infrastructure vendor that amended the existing agreement dated June 2017. The amended agreement expires in March 2022. The purchase commitment as of June 30, 2020 was $52.0 million f or the remaining period through the expiration of the agreement.

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 U.S. and 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 or otherwise seek to avoid their contracts with us as part of filing for bankruptcy protection, 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 a s 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.
Q2 2020 Financial Overview
In the second quarter of 2020, subscription revenue increased 21% and 30%, respectively for the three and six months ended June 30, 2020 as compared to the same periods in 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) of 8% and 14%, respectively, as compared to the three and six months of 2019, and accounted for 85% and 84% of total revenue for the three and six months ended June 30, 2020, respectively.
Cash used in operating activities was $47.0 million for the six months ended June 30, 2020, as compared to $11.6 million for the six months ended June 30, 2019. The increase in net cash used in operating activities was primarily attributable to higher cash operating expenses driven mainly by an increase in headcount and higher annual incentive payment as compared to prior year and customer requests to defer payments to the second half of fiscal year 2020. In addition, in response to the economic conditions caused by COVID-19, several customers delayed payments we expected to receive in the quarter which had an adverse impact on our reported net cash used in operating activities.
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
16

Table of Contents
evaluating the amount of cash generated by our business operations. Free cash flow used during the three months ended June 30, 2020 was $23.5 million, compared to $5.2 million for the three months ended June 30, 2019. Free cash flow used during the six months ended June 30, 2020 was $49.0 million, compared to $14.8 million for the six months ended June 30, 2019. This increase was primarily attributable to a $35.3 million increase in net cash used in operating activities primarily attributable to higher cash operating expenses driven mainly by an increase in headcount and higher annual incentive payment as compared to prior year and customer requests to defer payments to the second half of fiscal year 2020. The following is a reconciliation of free cash flow to the most comparable GAAP measure, net cash used in operating activities (in thousands):

| Three Months Ended June 30, |  |  |  | Six Months Ended June 30, |  |

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 working remotely since March 16, 2020. In addition, most of our customers are also working 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.
•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 quarter ended June 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 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.
•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 half 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 and develop new applications and technologies. While we continue to hire for certain strategic positions, we have slowed our rate of hiring in reaction to the COVID-19 environment.
•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.

Subscription revenue. Subscription revenue increased primarily due to an increased number of customer subscription contracts as compared to the prior year. 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.
Maintenance and support revenue. Maintenance and support revenue decreased primarily as result of migrating existing maintenance customers to our cloud solutions and to a lesser extent customer churn. We expect maintenance revenue to continue to decline over time as we migrate existing maintenance customers to our cloud solutions.
Services revenue. Services revenue decreased primarily as a result of performing implementation services for a reduced number of customers than in the prior year due to the impact of COVID-19. 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.

Cost of subscription. Cost of subscription increased primarily due to increased infrastructure costs to support our current subscription customer base and increased employee-related costs driven by higher headcount. Our subscription gross profit percentages were 71% and 72% for the three months ended June 30, 2020 and 2019, respectively, and 70% for the six months ended June 30, 2020 and 2019.
Cost of maintenance and support. Cost of maintenance and support decreased primarily due to a decrease in personnel costs. Maintenance and support gross profit percentages were 78% for the three and six months ended June 30, 2020, and 81% for the three and six months ended June 30, 2019.
Cost of services. Cost of services remained relatively unchanged for the three months ended June 30, 2020. Cost of services for the six months ended June 30, 2020 increased primarily due to increased employee-related costs driven by higher headcount and third party system integrators to support our current customer implementations, partially offset by a decrease in travel expenses. Services gross profit percentages for the three months ended June 30, 2020 and 2019, were (14)% and 20%, respectively. Services gross profit percentages for the six months ended June 30, 2020 and 2019, were (19)% and 19%, respectively. The decrease in services gross profit percentages was primarily attributed to a decrease in services revenue and an increase in headcount and in third party system integrators used to support customer implementations in 2020 as compared to 2019. Services gross profit percentages vary period to period depending on different factors, including the level of professional

services required to implement our solutions, our effective man-day rates, our utilization of third party system integrators and the utilization of our professional services personnel.
Gross profit. Overall gross profit decreased for the three months ended June 30, 2020 primarily due to an increase in total cost of revenue when total revenue remained unchanged for the period. The decrease in gross profit percentage primarily related to the decrease in services gross profit percentage for the period. Gross profit remained relatively consistent for the six months ended June 30, 2020.

Selling and marketing expenses. The three-month decrease in s ales and marketing expenses was primarily due to a decrease of $2.2 million in travel expenses and a $0.9 million decrease in expenses for sales and marketing events, partially offset by an increase of $1.2 million in employee-related costs driven by higher headcount. The six-month increase was primarily due to an increase of $4.2 million in employee-related costs driven by higher headcount as we continue to focus on adding new customers and increasing penetration within our existing customer base, and a $0.3 million increase in overhead costs. The increase was partially offset by a $2.4 million decrease in travel expenses and $0.6 million in expenses in sales and marketing events.
General and administrative expenses. General and administrative expenses increased primarily due to an increase of bad debt expense recognized as a result of increased credit risk from uncertain economic conditions caused by COVID-19 and the bankruptcy of several customers.
Research and development expenses. The three-month increase in research and development expenses was primarily due to a $1.2 million increase in employee-related costs driven by higher headcount, partially offset by a $0.3 million decrease in travel, facility and other overhead expenses. The six-month increase was primarily due to a $4.1 million increase in employee-related costs driven by higher headcount and an increase of $0.2 million in facility and other overhead expenses.

Convertible debt interest and amortization. The convertible debt expense for the three and six months ended June 30, 2020 and 2019 related to coupon interest and amortization of debt discount and issuance costs attributable to our Notes. Convertible debt interest and amortization decreased primarily as a result of our settlement of the 2019 Notes and 2047 Notes during 2019.
Other income (expense), net. The change in other income (expense), net for the three and six months ended June 30, 2020, primarily related to $2.3 million loss on debt extinguishment recognized in the second quarter of 2019 related to our 2019 Notes which was partially offset by a decrease in interest income during the periods.

Income tax provision. The tax provision for the three and six months ended June 30, 2020 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 (0.8)% and (0.7)% for the three and six months ended June 30, 2020, respectively, and (1.4)% and (1.3)% for the three and six months ended June 30, 2019, 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. While our expected tax rate would be 0% due to the full valuation on the deferred tax assets, the (0.8)% and (0.7)% for the three and six months ended June 30, 2020, respectively, and (1.4)% and (1.3)% for the three and six months ended June 30, 2019, 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 six months ended June 30, 2020.
Liquidity and Capital Resources
At June 30, 2020, we had $220.2 million of cash and cash equivalents and $130.7 million of working capital as compared to $306.1 million of cash and cash equivalents and $189.8 million of working capital at December 31, 2019.
Our principal sources of liquidity are our cash and cash equivalents, cash flows generated from operations and potential borrowings under our $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 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, the payments of our other liabilities and customer relief. 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, expansion into complementary 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 following table presents key components of our unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2020 and 2019:

Cash and cash equivalents (end of period) | $ | 220,157 |  |  | $ | 329,562 |

Operating Activities
Net cash used in operating activities for the six months ended June 30, 2020 was $47.0 million. The $35.3 million increase in cash used as compared to 2019 was primarily attributable to higher cash operating expenses driven mainly by an increase in headcount and higher annual incentive payment as compared to prior year and customer requests to defer payments to the second half of fiscal year 2020. In addition, in response to the economic conditions caused by COVID-19, several customers delayed payments we expected to receive in the quarter which had an adverse impact on our reported net cash used in operating activities.
Investing Activities
Net cash used in investing activities for the six months ended June 30, 2020 was $20.0 million, which was primarily related to capital expenditures of $19.2 million mainly attributable to the build out of our new headquarters and $0.8 million related to capitalized internal-use software development costs on our subscription service solutions.
Financing Activities
Net cash used in financing activities for the six months ended June 30, 2020 was $18.9 million, which was attributable to $20.2 million paid for tax withholdings on vesting of employee share-based awards, partially offset by proceeds from employee stock plans of $1.4 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 9 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 June 30, 2020. As of June 30, 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 six months ended June 30, 2020 and 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.

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 June 30, 2020 would result in a loss of approximately $0.2 million. W e 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 six months ended June 30, 2020 by approximately $0.4 million and $0.7 million, respectively. H owever, 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 options 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 June 30, 2020, we had no borrowings under the Revolver.
As of June 30, 2020, we had outstanding principal amount of $143.8 million of the 2024 Notes 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 June 30, 2020. Based on our evaluation of our disclosure controls and procedures as of June 30, 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
There have been no changes in our internal control over financial reporting during the three months ended June 30, 2020 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 provisions for credit losses in light of the adoption of Topic 326 on January 1, 2020. There were no significant changes to our internal control over financial reporting due to the adoption of Topic 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 risk factor:
We must successfully navigate the demand, supply and 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 certain of our customers experience downturns or uncertainty in their own business operations and revenue because of the economic effects, including from the spread of COVID-19, they have decreased spending on technology initiatives and in some cases stalled or halted various technology projects. 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. If a significant number of our customers are unable to continue as a going concern or make their contractually obligated payments to us, this would have an adverse impact on our business and financial condition. We may also have difficulty forecasting our bookings, revenue and cash flows given the tremendous uncertainty regarding the extent and duration of the pandemic.
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 quarter ended June 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 COVID-19 pandemic.
As COVID-19 has continued to spread throughout the U.S. and 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 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 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. As a result, new demand for our airline solutions has been limited during COVID-19, and we expect that new demand for these solutions will continue to be limited in the near term. In addition, implementation projects have been delayed and may continue to be delayed by current travel industry customers. There are no comparable recent events that provide guidance as to the effect of the spread of COVID-19 as a global pandemic, and a s 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.
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 through the end of 2020, 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 because our team is dispersed, many employees may 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 become sick), and employees may become sick themselves and be unable to work. The disruptions caused by COVID-19, including the limitations on meeting in-person with existing and potential customers and amongst our teams, may result in inefficiencies, delays and additional costs in our product development, sales, marketing and customer service efforts that we cannot fully mitigate through remote work arrangements. In addition, many of our customers are working remotely, which may delay the timing of new business and implementations of our services. If COVID-19 continues to have a substantial impact on our partners or customers, our results of operations and overall financial performance will be harmed. Furthermore, we have

and may continue to postpone or cancel planned investments in our business in response to changes in our business as a result of the spread of COVID-19, which may impact our product development and rate of innovation, either of which could seriously harm our business. Given the continued spread of COVID-19 and the resultant personal, economic and governmental reactions, we may have to take additional actions in the future that could further harm our business and financial performance.
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 more specifically;
•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 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, we may be unable to collect receivables from or renew subscription agreements with those customers significantly impacted by COVID-19. Also, a decrease in orders 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.
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.
