Notes to Condensed Consolidated Financial Statements

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, 2023, the results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' (deficit) equity for the three and six months ended June 30, 2023 and 2022.

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, 2022 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP.

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, 2022.

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 $171.2 million and $168.1 million at June 30, 2023 and December 31, 2022, 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 credit losses, 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 credit losses, 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

Table of Contents

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 revenue that have been recognized in advance of billing the customer.

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 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 also tied to the value of customer contracts acquired. Deferred costs were $14.5 million and $14.8 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred costs was $1.5 million and $1.4 million for the three months ended June 30, 2023 and 2022, respectively, and $2.9 million for both the six months ended June 30, 2023 and 2022. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive 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), associated with arrangements where professional services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts expected to be recoverable 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 $1.3 million and $1.6 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred implementation costs was $0.2 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and $0.4 million and $0.6 million for the six months ended June 30, 2023 and 2022, 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 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. During the three and six months ended June 30, 2023, the Company recorded zero impairment charge. During the three and six months ended June 30, 2022, the Company recorded zero and $1.6 million, respectively, of impairment charge related to fixed assets. The 2022 impairment resulted from the Company's changed intentions for these assets in connection with a new agreement with a software vendor.

Recently issued accounting pronouncements not yet adopted

There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.

3. Deferred Revenue and Performance Obligations

Deferred Revenue

For the three months ended June 30, 2023 and 2022, the Company recognized approximately $52.0 million and $48.6 million, respectively, and for the six months ended June 30, 2023 and 2022, the Company recognized approximately $81.5 million and $71.2 million, respectively, of revenue that was included in the deferred revenue balances at the beginning of the respective periods and primarily related to subscription, maintenance and support, and services.

Performance Obligations

As of June 30, 2023, the Company expects to recognize approximately $407.6 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 $204.2 million of these performance obligations over the next 12 months, with the balance recognized thereafter. Remaining performance obligations represent contractually committed revenue that has not yet been recognized, which includes deferred revenue and unbilled amounts that will be recognized as revenue in future periods.

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, 2023 and 2022. 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 10 years. Some of these leases include options to extend for up to 15 years, and some include options to terminate within 1 year.

As of June 30, 2023, the Company did not have any finance leases.

Supplemental cash flow information related to leases was as follows (in thousands):

Diluted loss per share	$	(0.29)	$	(0.50)	$	(0.70)	$	(1.13)

Dilutive potential common shares consist of shares issuable upon the vesting of restricted stock units ("RSUs"), market stock units ("MSUs") and equity consideration related to the EveryMundo LLC acquisition. Potential common shares determined to be antidilutive and excluded from diluted weighted average shares outstanding were approximately 1.7 million and 2.4 million, for the three months ended June 30, 2023 and 2022, respectively, and 1.7 million and 2.6 million for the six months ended June 30, 2023 and 2022, respectively. In addition, potential common shares related to the convertible notes determined to be antidilutive and excluded from diluted weighted average shares outstanding were 5.8 million for the three and six months ended June 30, 2023 and 2022.

7. Noncash Share-based Compensation

The Company's 2017 Equity Incentive Plan (as amended and restated, the "2017 Stock Plan") has an aggregate authorized limit of 7,650,000 shares for issuance.

At June 30, 2023, the Company had an estimated $91.0 million of total unrecognized compensation costs related to share-based compensation arrangements. These costs will be recognized over a weighted average period of 2.8 years.

The Company's Employee Stock Purchase Plan (as amended, the "ESPP") permits eligible employees to purchase Company shares on an after-tax basis in an amount between 1% and 10% of their annual pay: (i) on June 30 of each year at a 15% discount of the fair market value of the Company's common stock on January 1 or June 30, whichever is lower, and (ii) on December 31 of each year at a 15% discount of the fair market value of the Company's common stock on July 1 or December 31, whichever is lower. An employee may not purchase more than $5,000 in either of the six-month measurement periods described above or more than $10,000 annually. In May 2021, the Company's stockholders approved an amendment to the ESPP Plan increasing the aggregate amount of shares available for issuance under the ESPP to 1,000,000. During the three and six months ended June 30, 2023, the Company issued zero and 55,149 shares under the ESPP, respectively. As of June 30, 2023, 331,976 shares remain authorized and available for issuance under the ESPP. As of June 30, 2023, the Company held

approximately $1.0 million on behalf of employees for future purchases under the ESPP, and this amount was recorded in accrued payroll and other employee benefits in the Company's unaudited condensed consolidated balance sheet.

8. Convertible Senior Notes

The following is a summary of the Company's convertible senior notes as of June 30, 2023 (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	$	143,003	$	—	1%
2.25% Convertible Notes due in 2027 ("2027 Notes")	September 2020	$	150,000	$	—	$	147,522	2.25%

The 2027 and 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).

Interest related to the 2027 Notes is payable semiannually in arrears in cash on March 15 and September 15 of each year, beginning on March 15, 2021. Interest related to the 2024 Notes is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2019.

The 2027 Notes mature on September 15, 2027 and the 2024 Notes mature on May 15, 2024, unless redeemed or converted in accordance with their terms prior to such date. At June 30, 2023, the Company had $184.6 million of cash and cash equivalents. The Company believes its existing cash and cash equivalents, including current estimates of future operating cash flows and funds available under its $50 million Credit Agreement (see Note 11), will provide adequate liquidity and capital resources to meet its operational requirements, anticipated capital expenditures, coupon interest and principal payments for the Notes for the next twelve months. Capital markets have tightened recently in response to the macroeconomic environment making new financing more difficult and/or expensive and the Company may not be able to obtain such financing on terms acceptable to it.

Each $1,000 of principal of the 2027 Notes will initially be convertible into 23.9137 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $41.82 per share. 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 2027 and the 2024 Notes is subject to adjustment upon the occurrence of certain specified events.

As of June 30, 2023, the 2027 and 2024 Notes are not yet convertible and their remaining term is approximately 50 months and 10 months, respectively.

As of June 30, 2023 and December 31, 2022, the fair value of the principal amount of the Notes in the aggregate was $285.3 million and $263.7 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.

The Notes consist of the following (in thousands):


	June 30, 2023		December 31, 2022

Principal	$	293,750	$	293,750
Less: debt issuance cost, net of amortization	(3,225)		(3,971)
Net carrying amount	$	290,525	$	289,779

Total	$	1,576	$	1,576	$	3,152	$	3,152

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, 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 Notes, at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The Capped Call transactions are intended to reduce potential dilution to the Company’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amounts upon any conversion of 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 derivatives. The cost of the Capped Call was $25.3 million and $16.4 million for the 2027 and 2024 Notes, respectively, 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, mainly related to infrastructure platforms, business technology software and support, and other services. In January 2023, the Company entered into a noncancelable agreement for software support services with a four-year term. The remaining purchase commitment as of June 30, 2023 was $3.5 million and the agreement expires in March 2027. There were no other material changes outside the ordinary course of business to the noncancellable purchase commitments disclosed in the Annual Report.

10. Severance and Other Related Costs

In the first quarter of 2023, the Company made additional organizational changes and incurred approximately zero and $3.6 million of severance, employee benefits, outplacement and related costs during the three and six months ended June 30, 2023, respectively. These costs were recorded primarily as operating expenses in the unaudited condensed consolidated statements of comprehensive loss, mainly research and development, and sales and marketing. During the three and six months ended June 30, 2023, cash payments of $0.6 million and $3.7 million, respectively, were recorded for the incurred costs. The Company expects to settle the remaining accrued expense of approximately $0.7 million during the second half of 2023.

11. Subsequent Event

On July 21, 2023, the Company, through its wholly owned subsidiary PROS, Inc., entered into a three-year secured credit agreement ("Credit Agreement") with a bank lender providing for a revolving line of credit of up to $50 million, with interest paid monthly, at the 30-day secured overnight financing rate ("SOFR") plus an applicable margin of 4.25%. As of July 25, 2023, there were no borrowings outstanding under the Credit Agreement. The Company incurred approximately $0.8 million of debt issuance cost related to the Credit Agreement.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The terms “we,” “us,” “PROS” and “our” refer to PROS Holdings, Inc. and all of its subsidiaries that are consolidated in conformity with generally accepted accounting principles in the United States.

This management's discussion and analysis of financial condition and results of operations should be read along with the unaudited condensed consolidated financial statements and unaudited notes to unaudited condensed consolidated financial statements included in Part I, Item 1 ("Interim Condensed Consolidated Financial Statements (Unaudited)"), as well as the audited consolidated financial statements and notes to consolidated financial statements and management's discussion and analysis of financial condition and results of operations set forth in our Annual Report.

Q2 2023 Financial Overview

In the second quarter of 2023, we continued to grow our subscription revenue, increasing subscription revenue by 14% for both the three and six months ended June 30, 2023, each as compared to the same period in 2022. Total revenue increased 11% and 10% for the three and six months ended June 30, 2023, respectively, as compared to the same periods in 2022.

For the three and six months ended June 30, 2023, recurring revenue (which consists of subscription revenue and maintenance and support revenue) accounted for 82% and 83% of total revenue, respectively. Recurring revenue accounted for 84% and 85% of total revenue for the three and six months ended June 30, 2022, respectively. Our gross revenue retention rates remained above 93% during the twelve months ended June 30, 2023.

Cash used in operating activities was $12.7 million for the six months ended June 30, 2023 and remained relatively consistent as compared to $12.9 million for the six months ended June 30, 2022.

Free cash flow is a 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, excluding severance payments, less capital expenditures, 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 June 30, 2023 was $6.2 million, compared to $2.2 million for the three months ended June 30, 2022. The increase primarily related to timing of collections and an increase in marketing events payments. Free cash flow used during the six months ended June 30, 2023 was $10.8 million, compared to $13.7 million for the six months ended June 30, 2022. The improvement was primarily attributable to increased cash collections during the period and a lower annual incentive payment in 2023 as compared to prior year. 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,
	2023		2022		2023		2022
Net cash used in operating activities	$	(6,542)	$	(1,931)	$	(12,685)	$	(12,945)
Severance	579		—		3,749		—

Free Cash Flow	$	(6,240)	$	(2,239)	$	(10,759)	$	(13,714)

Factors Affecting Our Performance

Key factors and trends that have affected, and we believe will continue to affect, our operating results include:

•Macroeconomic Environment. The industries and companies we serve are navigating a complex macroeconomic environment impacted by inflation, higher interest rates, volatile capital and financial markets, supply chain disruptions, tight labor markets, pricing volatility, the Russia-Ukraine conflict, and other local and regional macroeconomic conditions. In this challenging and constantly changing environment, we remain confident in our ability to help optimize shopping and selling experiences for our customers. For example, pricing volatility and inflation are catalysts for demand for our price management and optimization solutions, and the pace of change is driving businesses to replace manual selling processes with our AI-powered digital solutions. Partly, as a result, we grew both subscription revenue and total revenue by double digits in the first half of 2023. Because uncertain macroeconomic and industry conditions in countries and regions in which we operate create a challenging selling

Table of Contents

environment for large enterprise technology deployments, we believe in the near term that new customers increasingly will emphasize smaller scope initial purchases with faster implementations. While our recurring revenue and earnings are relatively predictable as a result of our subscription-based business model, the broader implications of these macroeconomic events on our business, results of operations, cash flows and overall financial position, particularly in the long term, remain uncertain. Under this model, our lower subscription bookings during the pandemic adversely impacted our subscription revenue growth rates in subsequent periods due to the timing lag between subscription bookings and the revenue recognized on those bookings. For a full discussion on the risks and uncertainties to our business, please see the "Risk Factors" section in our Annual Report.

•Profitable Growth as a Priority. We believe our market opportunity is large and underpenetrated, and we intend to continue investing in our business to create awareness for our solutions, acquire new customers, and expand within our existing customer base globally. We are also focusing on our cash flow and profitability, and plan to mitigate the growth in our costs and reduce our existing cost structure. We also plan to continue investing in product development to enhance our existing technologies. This includes initiatives to accelerate customer time-to-value, improve efficiency, provide out-of-the-box integration with third-party commerce solutions and develop new applications and technologies.

•Travel Industry Recovering. Despite operational headwinds and regional variances in the timing of travel restrictions being lifted, the travel industry, particularly the airline industry, continues to recover from the unprecedented disruption caused by the pandemic. While global capacity has not fully returned to pre-pandemic levels, demand for air travel continues to increase as restrictions have been lifted. North American travel has led this recovery with Asia Pacific lagging, particularly as China only recently lifted international travel restrictions. The International Air Transport Association forecasts airline industry profitability in 2023 with certain U.S.-based airlines already publicly reporting profitable quarters. However, the rate of airline industry recovery and profitability could be impacted negatively if inflation impacts consumer disposable income or if business travel does not recover to pre-pandemic levels. While we expect airlines to increasingly prioritize technology investments as travel returns to pre-COVID levels, most of our airline industry customers are based outside the U.S. and there is significant geographic and individual airline variation in pace of recovery and capacity for technology projects.

•Digital Purchasing Driving Technology Adoption. We believe the long-term trends toward digital purchasing by both consumers and corporate buyers drives demand for technology that provides fast, frictionless and personalized buying experiences across direct sales, partner, online, mobile and emerging channels. Buyers often prefer not to interact with sales representatives as their primary source of research, and to buy online when they have already decided what to buy. For example, in the airline industry, the pandemic accelerated a long-term trend towards direct booking channels, and we anticipate airlines continuing to invest in technology, including mobile device-enabled solutions, to enhance their ability to capture a greater percentage of bookings through their own channels such as their websites. We believe companies must adopt technologies which power these types of experiences across sales channels as they modernize their sales process to compete in digital commerce.

•Artificial Intelligence Becoming Mainstream. Recent mainstream adoption of generative AI and associated media attention on AI are driving increased interest and conversations by companies around business applications leveraging AI. For example, companies are looking to AI to quickly extract actionable insights from their data, improve and customize their offerings, and drive process and operating efficiencies. Our AI-powered solutions enable buyers to move fluidly and with personalized experiences across our customers’ sales channels, and our digital offer marketing solutions help our customers drive their buyers directly into their direct selling channels. Our solutions have utilized AI for years, and our legacy of AI development continues to influence our category-leading solutions. For example, our platform is now powered by our 4th generation AI, using a deep neural network that leverages all available data and attributes to improve prediction accuracy.

•Cloud Migrations. We continue to encourage our customers to migrate to our current cloud solutions as we discontinue support for certain of our on-premises solutions. As our on-premises customers continue to migrate from our legacy solutions to our current cloud solutions, we expect our future maintenance and support revenue will continue to decline and our subscription revenue will increase.

Subscription revenue. Subscription revenue increased primarily due to an increase in new and existing customer subscription contracts.

Maintenance and support revenue. Maintenance and support revenue decreased primarily as a result of existing maintenance customers migrating to our cloud solutions and, to a lesser extent, customer maintenance churn. We expect maintenance revenue to continue to decline as we continue to migrate maintenance customers to our cloud solutions.

Services revenue. Services revenue increased primarily as a result of higher sales of professional services related to our subscription contracts and follow-on professional services to existing customers. 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 efficiencies in our solutions implementations requiring less professional services during a particular period.

Cost of subscription. Cost of subscription increased slightly primarily due to increased infrastructure cost to support the increase in our current subscription customer base and higher employee-related costs mainly due to increase in headcount. The increase was partially offset by a decrease in amortization expense for intangible assets for the three and six months ended June 30, 2023, and internal-use software expense for the six months ended June 30, 2023. Our subscription gross profit percentages were 75% and 73% for the three months ended June 30, 2023 and 2022, respectively, and 75% and 72% for the six months ended June 30, 2023 and 2022, respectively.

Cost of maintenance and support. During the three months ended June 30, 2023, cost of maintenance and support decreased due to a decrease in personnel costs as a result of the need to support a declining maintenance customer base due to migrations to our subscription solutions. During the six months ended June 30, 2023, cost of maintenance and support remained relatively unchanged as compared to the same period in 2022. Maintenance and support gross profit percentages were 63% and 73% for the three months ended June 30, 2023 and 2022, respectively, and 62% and 72% for the six months ended June 30, 2023 and 2022, respectively. Gross profit percentages decreased primarily due to lower maintenance and support revenue as we continue to migrate customers to our subscription solutions and the cost of maintenance and support being relatively fixed.

Cost of services. Cost of services increased primarily due to higher personnel costs to support the increase in our services revenue during the period. Services gross profit percentages were 6% and (11)% for the three months ended June 30, 2023 and 2022, respectively, and (4)% and (13)% for the six months ended June 30, 2023 and 2022, respectively. Services gross profit percentages improved in 2023 compared to 2022 primarily due to an increase in services revenue and a lesser increase in cost of services due to greater efficiencies. Services gross profit percentages vary period to period depending on different factors, including the level of professional services required to implement our solutions, the utilization of our employees and our effective man-day rates.

Selling and marketing expenses. During the three and six months ended June 30, 2023, selling and marketing expenses increased primarily due to an increase in sales and marketing events and initiatives, and travel expenses. The increase was partially offset by a decrease in employee-related costs mainly due to prior organizational changes and a decrease in intangible asset amortization expense.

Research and development expenses. During the three months ended June 30, 2023, research and development expenses decreased primarily due to a decrease in employee-related costs mainly due to prior organizational changes and a

Table of Contents

decreased use of contracted resources. During the six months ended June 30, 2023, research and development expenses decreased primarily due to a decrease in noncash share-based compensation and a decreased use of contracted resources. The noncash share-based compensation was higher in prior year mainly due to the acceleration of equity awards related to the retirement of a senior officer in the first quarter of 2022.

General and administrative expenses. As a result of our efforts to find greater efficiencies, general and administrative expenses remained relatively consistent for the three and six months ended June 30, 2023 as compared with the same periods in 2022.

Impairment of fixed assets. During the six months ended June 30, 2023 and 2022, we recorded zero and $1.6 million impairment charge related to fixed assets, respectively. The 2022 impairment resulted from changes to our intentions for certain fixed assets in connection with a new agreement with a software vendor.

Convertible debt interest and amortization. Convertible debt expense for the three and six months ended June 30, 2023 and 2022 related to coupon interest and amortization of debt issuance costs attributable to our Notes.

Other income (expense), net. The change in other income (expense), net for the three and six months ended June 30, 2023, primarily related to higher interest income mainly driven by an increase in interest rates in 2023 as compared to prior year, and to a lesser extent due to foreign currency fluctuations.

Income tax provision:


	Three Months Ended June 30,						Variance				Six Months Ended June 30,						Variance
(Dollars in thousands)	2023			2022			$		%		2023			2022			$		%

Income tax provision	$	149		$	291		$	(142)	(49)	%	$	230		$	434		$	(204)	(47)	%

Income tax provision. The tax provision for the three and six months ended June 30, 2023 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 (1.1)% and (1.3)% for the three months ended June 30, 2023 and 2022, respectively, and (0.7)% and (0.9)% for the six months ended June 30, 2023 and 2022, respectively. The income tax rate varies from the 21% federal statutory rate primarily due to the valuation allowances on our deferred tax assets. While our expected tax rate would be 0% due to the full valuation allowance on our deferred tax assets, the income tax provision and related effective tax rates is due to foreign income and withholding taxes.

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.

Liquidity and Capital Resources

At June 30, 2023, we had $184.6 million of cash and cash equivalents and $(48.6) million of working capital as compared to $203.6 million of cash and cash equivalents and $106.3 million of working capital at December 31, 2022. The change in working capital was mainly driven by our 2024 Notes, with a principal amount of $143.8 million, which became a current liability in the second quarter of 2023.

Table of Contents

Our principal sources of liquidity are our cash and cash equivalents, cash flows generated from operations and potential borrowings under our $50 million Credit Agreement, see Note 11 for details. In addition, we could access capital markets to supplement our 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 issuance costs) and the timing of invoicing and cash collections from our customers. Our operating cash flows are also impacted by the timing of payments to our vendors and the payments of other liabilities.

We believe our existing cash and cash equivalents, including current estimates of future operating cash flows and funds available under our Credit Agreement, will provide adequate liquidity and capital resources to meet our operational requirements, anticipated capital expenditures, coupon interest and principal payments for our Notes for the next twelve months. Our future working capital requirements depend on many factors, including the operations of our existing business, growth of our customer subscription services, future acquisitions we might undertake, expansion into complementary businesses, timing of adoption and implementation of our solutions and customer churn. Capital markets have tightened in response to the macroeconomic environment making new financing more difficult and/or expensive and we may not be able to obtain such financing on terms acceptable to us. During the first half of 2023, the financial markets experienced disruption due to certain bank failures. We have not experienced any material impact from the disruption but will continue to monitor the situation and take action accordingly.

The following table presents key components of our unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2023 and 2022:


	Six Months Ended June 30,
(Dollars in thousands)	2023		2022
Net cash used in operating activities	$	(12,685)	$	(12,945)
Net cash used in investing activities	(1,823)		(938)
Net cash (used in) provided by financing activities	(4,531)		1,231
Cash and cash equivalents (beginning of period)	203,627		227,553
Cash and cash equivalents (end of period)	$	184,567	$	215,178

Operating Activities

Net cash used in operating activities for the six months ended June 30, 2023 was $12.7 million and remained relatively consistent with prior year. While we had an improvement of $18.8 million in net loss period over period, it was mainly offset by changes in our working capital.

Investing Activities

Net cash used in investing activities for the six months ended June 30, 2023 was $1.8 million. The increase was due to higher capital expenditures, primarily related to third-party software license renewal, in 2023 as compared to the same period in prior year.

Financing Activities

Net cash used in financing activities for the six months ended June 30, 2023 was $4.5 million. The increase was primarily attributable to higher tax withholding payments on the vesting of employee share-based awards, an increase of $5.5 million in cash used as compared to the same period in 2022.

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.

Table of Contents

Contractual Obligations and Commitments

Other than changes described in Note 9 above and noted below, there have been no material changes to our contractual obligations and commitments disclosed in our Annual Report.

Our Credit Agreement contains affirmative and negative covenants, including covenants which restrict our ability to, among other things, create liens, incur additional indebtedness and engage in certain other transactions, in each case subject to certain exclusions. In addition, our Credit Agreement contains certain financial covenants which become effective in the event our liquidity (as defined in the Credit Agreement) falls below a certain level.

Recent Accounting Pronouncements

See "Recently issued accounting pronouncements not yet adopted" in Note 2 above for discussion of recent accounting pronouncements including the respective expected dates of adoption, if any.

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 credit losses, 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 awards, 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, 2023 would result in a loss of approximately $0.7 million. We are also exposed to foreign currency risk due to our operating subsidiaries in France, United Kingdom, Canada, Germany, Ireland, Australia, Bulgaria, Ecuador 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, 2023 by approximately $1.2 million and $2.3 million, respectively. 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 derivatives in future years.

Interest Rate Risk

As of June 30, 2023, we had outstanding principal amounts of $150.0 million and $143.8 million of the 2027 and the 2024 Notes, respectively, 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, 2023. Based on our evaluation of our disclosure controls and procedures as of June 30, 2023, 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, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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

Other than as set forth below, there have been no material changes in the Company's risk factors from those disclosed in Part I, Item 1A, of our Annual Report.

We incurred indebtedness by issuing convertible notes, we may borrow under our Credit Agreement, and our debt repayment obligations may adversely affect our financial condition and cash flows 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 June 30, 2023, 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" and together with the 2027 Notes, the "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 June 30, 2023, the entire $143.8 million of aggregate principal amount of 2024 Notes are outstanding.

Our Credit Agreement provides for a $50.0 million revolving line of credit, none of which was drawn as of July 25, 2023. The Credit Agreement contains affirmative and negative covenants, including covenants which restrict our ability to, among other things, create liens, incur additional indebtedness and engage in certain other transactions, in each case subject to certain exclusions. In addition, the Credit Agreement contains certain financial covenants which become effective in the event our liquidity (as defined in the Credit Agreement) falls below a certain level. The Credit Agreement contains customary events of default relating to, among other things, payment defaults, breach of covenants, cross acceleration to material indebtedness, bankruptcy-related defaults, judgment defaults, and the occurrence of certain change of control events. The occurrence of an event of default may result in the termination of the Credit Agreement and acceleration of repayment obligations with respect to any outstanding principal amounts.

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. 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, 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 June 30, 2023, $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 June 30, 2023.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

Table of Contents

ITEM 4. MINE SAFETY DISCLOSURE

None.

ITEM 5. OTHER INFORMATION

During the three months ended June 30, 2023, no director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

Summary of Significant Accounting Policies (Notes)	Jun. 30, 2023
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	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, 2023, the results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' (deficit) equity for the three and six months ended June 30, 2023 and 2022. 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, 2022 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP. 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, 2022. 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 $171.2 million and $168.1 million at June 30, 2023 and December 31, 2022, 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 credit losses, 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 credit losses, 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 revenue that have been recognized in advance of billing the customer. 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 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 also tied to the value of customer contracts acquired. Deferred costs were $14.5 million and $14.8 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred costs was $1.5 million and $1.4 million for the three months ended June 30, 2023 and 2022, respectively, and $2.9 million for both the six months ended June 30, 2023 and 2022. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive 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), associated with arrangements where professional services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts expected to be recoverable 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 $1.3 million and $1.6 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred implementation costs was $0.2 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and $0.4 million and $0.6 million for the six months ended June 30, 2023 and 2022, 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 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. During the three and six months ended June 30, 2023, the Company recorded zero impairment charge. During the three and six months ended June 30, 2022, the Company recorded zero and $1.6 million, respectively, of impairment charge related to fixed assets. The 2022 impairment resulted from the Company's changed intentions for these assets in connection with a new agreement with a software vendor. Recently issued accounting pronouncements not yet adopted There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.

Deferred Revenue and Performance Obligation [Abstract]
Deferred revenue and performance obligation [Text Block]	Deferred Revenue and Performance Obligations Deferred Revenue For the three months ended June 30, 2023 and 2022, the Company recognized approximately $52.0 million and $48.6 million, respectively, and for the six months ended June 30, 2023 and 2022, the Company recognized approximately $81.5 million and $71.2 million, respectively, of revenue that was included in the deferred revenue balances at the beginning of the respective periods and primarily related to subscription, maintenance and support, and services. Performance Obligations As of June 30, 2023, the Company expects to recognize approximately $407.6 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 $204.2 million of these performance obligations over the next 12 months, with the balance recognized thereafter. Remaining performance obligations represent contractually committed revenue that has not yet been recognized, which includes deferred revenue and unbilled amounts that will be recognized as revenue in future periods.

Summary of Significant Accounting Policies (Policies)	Jun. 30, 2023
Accounting Policies [Abstract]
Basis of presentation	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, 2023, the results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' (deficit) equity for the three and six months ended June 30, 2023 and 2022. 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, 2022 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2022 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP.
Accounting Standards Update and Change in Accounting Principle	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, 2022.
Fair value measurement	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 $171.2 million and $168.1 million at June 30, 2023 and December 31, 2022, 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 Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]	Trade and other receivables Trade and other receivables are primarily comprised of trade receivables, net of allowance for credit losses, 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 credit losses, 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 revenue that have been recognized in advance of billing the customer.
Revenue Recognition, Customer Acquisitions [Policy Text Block]	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 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 also tied to the value of customer contracts acquired. Deferred costs were $14.5 million and $14.8 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred costs was $1.5 million and $1.4 million for the three months ended June 30, 2023 and 2022, respectively, and $2.9 million for both the six months ended June 30, 2023 and 2022. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive loss.
Deferred Charges, Policy [Policy Text Block]	Deferred implementation costsThe Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), associated with arrangements where professional services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts expected to be recoverable 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 $1.3 million and $1.6 million as of June 30, 2023 and December 31, 2022, respectively. Amortization expense for the deferred implementation costs was $0.2 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and $0.4 million and $0.6 million for the six months ended June 30, 2023 and 2022, 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 loss.
Impairment or Disposal of Long-Lived Assets, Policy	Impairment of Long-Lived AssetsLong-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. During the three and six months ended June 30, 2023, the Company recorded zero impairment charge. During the three and six months ended June 30, 2022, the Company recorded zero and $1.6 million, respectively, of impairment charge related to fixed assets. The 2022 impairment resulted from the Company's changed intentions for these assets in connection with a new agreement with a software vendor.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently issued accounting pronouncements not yet adopted There have been no recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2023, as compared to the recent accounting pronouncements described in the Company's Annual Report, that are of significance or potential significance to the Company.
