Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	1. GENERAL We have prepared the accompanying unaudited condensed consolidated financial statements as of June 30, 2024 and December 31, 2023, and for the quarters and six months ended June 30, 2024 and 2023, in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) for interim financial information, and pursuant to the instructions to Form 10-Q and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of our management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of our financial position and operating results have been included. The unaudited Condensed Consolidated Financial Statements (the “Financial Statements”) should be read in conjunction with the Consolidated Financial Statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), contained in our Annual Report on Form 10-K for the year ended December 31, 2023 (our “2023 10-K”), filed with the SEC. The results of operations for the quarter and six months ended June 30, 2024 are not necessarily indicative of the expected results for the entire year ending December 31, 2024 .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates in Preparation of Financial Statements. The preparation of our Financial Statements requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our Financial Statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Revenue. The majority of our future revenue is related to our customer contracts for our SaaS and related solutions that include variable consideration dependent upon a series of monthly volumes and/or daily usage of services and have contractual terms ending from 2024 through 2036 . Our customer contracts may include guaranteed minimums and fixed monthly or annual fees. As of June 30, 2024 , our aggregate amount of the transaction price allocated to the remaining performance obligations was approximately $ 1.4 billion, which is made up of fixed fee consideration and guaranteed minimums expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). We expect to recognize approximately 75 % of this amount by the end of 2026 , with the remaining amount recognized by the end of 2036 . We have excluded from this amount variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied. The nature, amount, timing, and uncertainty of our revenue and how revenue and cash flows are affected by economic factors is most appropriately depicted by revenue type, geographic region, and customer vertical. Revenue by type for the quarters and six months ended June 30, 2024 and 2023 was as follows (in thousands): Quarter Ended Six Months Ended June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 SaaS and related solutions $ 262,658 $ 255,600 $ 524,353 $ 513,476 Software and services 14,681 18,766 37,075 49,657 Maintenance 12,979 11,961 24,025 21,933 Total revenue $ 290,318 $ 286,327 $ 585,453 $ 585,066 We use the location of the customer as the basis of attributing revenue to geographic regions.

Deferred revenue recognized during the six months ended June 30, 2024 and 2023 was $ 29.8 million and $ 31.5 million, respectively. Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less as of the date of purchase to be cash equivalents. As of June 30, 2024 and December 31, 2023, our cash equivalents consist primarily of institutional money market funds and time deposits held at major banks. For the cash and cash equivalents denominated in foreign currencies and/or located outside the U.S., we do not anticipate any material amounts being unavailable for use in running our business, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls and potential negative economic consequences. Restricted Cash. Restricted cash includes cash that is legally or contractually restricted, as well as our settlement and merchant reserve assets (discussed below). The nature of the restrictions on our settlement and merchant reserve assets consists of contractual restrictions with the merchants and restrictions arising from our policy and intention. It has historically been our policy to segregate settlement and merchant reserve assets from our operating cash balances and our intention is to continue to do so. As of June 30, 2024 and December 31, 2023, we had $ 3.1 million and $ 2.9 million, respectively, of restricted cash that mainly serves to collateralize bank and performance guarantees included in other current and non-current assets in our unaudited Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”). Settlement and Merchant Reserve Assets and Liabilities. Settlement assets and settlement liabilities represent cash collected on behalf of merchants via payments processing services which is held for an established holding period until settlement with the customer. The holding period is generally one to four business days depending on the payment model and contractual terms with the customer. During the holding period, cash is subject to restriction and segregation based on the nature of our custodial relationship with the merchants. Should we fail to remit these funds to our merchants, the merchant's sole recourse for payment would be against us. These rights and obligations are set forth in the contracts between us and the merchants. Settlement assets are held with various major financial institutions and a corresponding liability is recorded for the amounts owed to the customer. At any given time, there may be differences between the cash held and the corresponding liability due to the timing of operating-related cash transfers. Merchant reserve assets/liabilities represent deposits collected from merchants to mitigate our risk of loss due to nonperformance of settlement obligations initiated by those merchants using our payments processing services, or non-payment by customers for services rendered by us. We perform a credit risk evaluation on each customer based on multiple criteria, which provides the basis for the deposit amount required for each merchant. For the duration of our relationship with each merchant, we hold their reserve deposits with major financial institutions. We hold these funds in separate accounts, which are offset by corresponding liabilities. The following table summarizes our settlement and merchant reserve assets and liabilities as of the indicated periods (in thousands): June 30, 2024 December 31, 2023 Assets Liabilities Assets Liabilities Settlement assets/liabilities $ 216,485 $ 214,067 $ 260,712 $ 259,825 Merchant reserve assets/liabilities 15,569 15,569 13,987 13,992 Total $ 232,054 $ 229,636 $ 274,699 $ 273,817 Financial Instruments . Our financial instruments as of June 30, 2024 and December 31, 2023 include cash and cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, accounts payable, and debt. Due to their short maturities, the carrying amounts of cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, and accounts payable approximate their fair value. We have chosen not to record our debt at fair value, with changes recognized in earnings each reporting period. The following table indicates the carrying value and estimated fair value of our debt as of the indicated periods (in thousands): June 30, 2024 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value 2023 Convertible Notes (par value) $ 425,000 $ 396,483 $ 425,000 $ 428,506 2021 Credit Agreement (carrying value including 129,375 129,375 133,125 133,125 The fair value of our convertible notes was estimated based upon quoted market prices or recent sales activity, while the fair value of our credit agreement was estimated using a discounted cash flow methodology, both of which are considered Level 2 inputs. See Note 4 for a discussion regarding our debt. Pillar Two. Numerous foreign jurisdictions have enacted, or are in the process of enacting, legislation to adopt a minimum effective tax rate. Pillar Two, which was established by the Organization for Economic Co-operation and Development (OECD), generally provides for a 15% minimum effective tax rate for multinational enterprises in every jurisdiction in which they operate. The U.S. has not yet adopted Pillar Two, however, various other governments around the world have. These rules did not have a material impact on our taxes for the quarter and six months ended June 30, 2024 . We continue to monitor evolving tax legislation in the jurisdictions in which we operate. Accounting Pronouncements Issued but Not Yet Effective. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) , (“ASU 2023-07”), which enhances reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. ASU 2023-07 also requires disclosure of the title and position of the company’s Chief Operating Decision Maker (“CODM”) and how the CODM uses financial reporting to assess segment performance and allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires entities to disclose more detailed information about their effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures.

The 2023 Convertible Notes will be convertible at the option of the noteholders before June 15, 2028, upon the occurrence of certain events. On or after June 15, 2028, and until the close of business on the second scheduled trading day immediately preceding September 15, 2028, the maturity date, noteholders may convert all or any portion of their notes at any time regardless of these conditions. The 2023 Convertible Notes will be convertible at an initial conversion rate of 14.0753 shares of our common stock per $ 1,000 principal amount of the 2023 Convertible Notes, which is equivalent to an initial conversion price of $ 71.05 per share of our common stock, plus carryforward adjustments not yet effected pursuant to the terms of the indenture governing the 2023 Convertible Notes. Under the terms of the 2023 Convertible Notes, we will adjust the conversion rate for any quarterly dividends exceeding $ 0.28 per share. We are required to satisfy our conversion obligation as follows: (i) paying cash up to the aggregate principal amount of notes to be converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we will satisfy the remaining conversion obligation in our common stock, cash, or a combination thereof, at our election. As of June 30, 2024, none of the conditions to early convert have been met. We may not redeem the 2023 Convertible Notes prior to September 21, 2026. On or after September 21, 2026 , we may redeem for cash all or part of the 2023 Convertible Notes, subject to a partial redemption limitation that requires at least $ 100.0 million of the principal amount of the 2023 Convertible Notes to remain outstanding if the last reported sales price of our common stock has been at least 130 % of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. The redemption price will equal the principal amount of the 2023 Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund has been established for the 2023 Convertible Notes. In connection with the pricing of the 2023 Convertible Notes, we entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain of the initial purchasers of the 2023 Convertible Notes and other financial institutions (collectively, the “Option Counterparties”). As of June 30, 2024, all the Capped Call Transactions were outstanding and cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2023 Convertible Notes, 5.98 million shares of our common stock, the same number of shares of common stock underlying the 2023 Convertible Notes. The Capped Call Transactions will expire upon the maturity of the 2023 Convertible Notes. 2021 Credit Agreement. During the six months ended June 30, 2024, we made $ 3.8 million of principal repayments on our $ 150.0 million aggregate principal five-year term loan (the “2021 Term Loan”).

As of June 30, 2024 , our interest rate on the 2021 Term Loan was 6.810 % (adjusted Secured Overnight Financing Rate ("SOFR") , credit spread adjustment of 0.10 %, plus 1.375 % per annum), effective through September 2024, and our commitment fee on the 2021 Revolver was 0.15 %. The interest rates under the 2021 Credit Agreement are based upon our choice of an adjusted SOFR rate plus an applicable margin of 1.375 % - 2.125 %, or an alternate base rate (“ABR”) plus an applicable margin of 0.375 % - 1.125 %, with the applicable margin determined in accordance with our then-net secured total leverage ratio. We pay a commitment fee of 0.150 % - 0.325 % of the average daily unused amount of the 2021 Revolver, with the commitment fee rate also determined in accordance with our then-net secured total leverage ratio. Other . We finance certain of our internal use software. During the second quarter of 2024, we entered into an additional financing agreement at a total cost of $ 8.4 million with payments through 2027. As a result, as of June 30, 2024, we had $ 9.0 million outstanding under these agreements, of which $ 3.2 million was included in other current liabilities and $ 5.8 million was included in other noncurrent liabilities in our Balance Sheet.

Commitments, Guarantees and Contingencies	7. COMMITMENTS, GUARANTEES AND CONTINGENCIES Guarantees . In the ordinary course of business, we may provide guarantees in the form of bid bonds or performance bonds. As of June 30, 2024, we had $ 3.1 million of restricted assets used to collateralize these guarantees, with $ 0.9 million included in other current assets and $ 2.2 million included in other non-current assets. We have performance guarantees in the form of surety bonds and standby letters of credit, along with money transmitter bonds, issued through third-parties that are not required to be reflected on our Balance Sheets. As of June 30, 2024 , we had performance guarantees of $ 7.3 million, which includes $ 1.5 million in standby letters of credit and $ 1.0 million in bid bonds. We are ultimately liable for claims that may occur against these guarantees. We have no history of material claims or are aware of circumstances that would require us to pay under any of these arrangements. We also believe that the resolution of any claim that may arise in the future, either individually or in the aggregate, would not be material to our Financial Statements. As of June 30, 2024 , we had total aggregate money transmitter bonds of $ 19.6 million outstanding. These money transmitter bonds are for the benefit of various states to comply with the states’ financial requirements and industry regulations for money transmitter licenses. Warranties. We generally warrant that our solutions and related offerings will conform to published specifications, or to specifications provided in an individual customer arrangement, as applicable. The typical warranty period is 90 days from the date of acceptance of the solution or offering. For certain service offerings we provide a warranty for the duration of the services provided. We generally warrant that those services will be performed in a professional and skillful manner. The typical remedy for breach of warranty is to correct or replace any defective deliverable, and if not possible or practical, we will accept the return of the defective deliverable and refund the amount paid under the customer arrangement that is allocable to the defective deliverable. Our contracts also generally contain limitation of damages provisions in an effort to reduce our exposure to monetary damages arising from breach of warranty claims. Historically, we have incurred minimal warranty costs, and as a result, do not maintain a warranty reserve. Solution and Services Indemnifications. Arrangements with our customers generally include an indemnification provision that will indemnify and defend a customer in actions brought against the customer that claim our products and/or services infringe upon a copyright, trade secret, or valid patent. Historically, we have not incurred any significant costs related to such indemnification claims, and as a result, do not maintain a reserve for such exposure. Claims for Company Non-performance. Our arrangements with our customers typically limit our liability for breach to a specified amount of the direct damages incurred by the customer resulting from the breach. From time-to-time, these arrangements may also include provisions for possible liquidated damages or other financial remedies for our non-performance, or in the case of certain of our solutions, provisions for damages related to service level performance requirements. The service level performance requirements typically relate to system availability and timeliness of service delivery. As of June 30, 2024, we believe we have adequate reserves, based on our historical experience, to cover any reasonably anticipated exposure as a result of our nonperformance for any past or current arrangements with our customers. Indemnifications Related to Officers and the Board of Directors. Other guarantees include promises to indemnify, defend, and hold harmless our directors, and certain officers. Such indemnification covers any expenses and liabilities reasonably incurred by a person, by reason of the fact that such person is, was, or has agreed to be a director or officer, in connection with the investigation, defense, and settlement of any threatened, pending, or contemplated action, suit, proceeding, or claim. We maintain directors’ and officers’ (“D&O”) insurance coverage to protect against such losses. We have not historically incurred any losses related to these types of indemnifications and are not aware of any pending or threatened actions or claims against any officer or member of our Board of Directors (the "Board"). As a result, we have not recorded any liabilities related to such indemnifications as of June 30, 2024. In addition, as a result of the insurance policy coverage, we believe these indemnification agreements are not significant to our results of operations. Legal Proceedings. From time to time, we are involved in litigation relating to claims arising out of our operations in the normal course of business.

We currently have a stock repurchase program, approved by our Board, authorizing us to repurchase shares of our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). During the second quarter and six months ended June 30, 2024 , we repurchased approximately 219,000 shares of our common stock for $ 9.7 million (weighted-average price of $ 44.32 per share), and approximately 404,000 shares of our common stock for $ 19.3 million (weighted-average price of $ 47.82 per share), respectively, under a SEC Rule 10b5-1 Plan. We did not make any share repurchases during the second quarter and six months ended June 30, 2023. The excise tax imposed as part of the 2022 Inflation Reduction Act, which is included as a cost of treasury stock, is not reflected in the share repurchase amounts above. As of June 30, 2024 , the total remaining value of shares available for repurchase under the Stock Repurchase Program totaled $ 76.5 million. In August 2024, our Board authorized an additional $ 100.0 million of repurchases under the Stock Repurchase Program in addition to the $ 76.5 million that remained as of June 30, 2024, with the combined total now authorized for repurchase through December 31, 2025 .

In addition to the above-mentioned stock repurchases, during the second quarters of 2024 and 2023 , we repurchased and then cancelled approximately 9,000 shares of common stock for $ 0.4 million and approximately 2,000 shares of common stock for $ 0.1 million, respectively , and during the six months ended June 30, 2024 and 2023 , we repurchased and then cancelled approximately 168,000 shares of common stock for $ 8.9 million and approximately 168,000 shares of common stock for $ 9.4 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plan. Cash Dividends. During the second quarter of 2024 , our Board approved a quarterly cash dividend of $ 0.30 per share of common stock, totaling $ 8.8 million. During the second quarter of 2023 , our Board approved a quarterly cash dividend of $ 0.28 per share of common stock, totaling $ 8.9 million. Dividends declared for the six months ended June 30, 2024 and 2023 totaled $ 17.6 million and $ 17.7 million, respectively. Warrants . In July 2014, in conjunction with the execution of an amendment to our agreement with Comcast Corporation (“Comcast”), we issued stock warrants (the “Warrant Agreement”) for the right to purchase up to 2.9 million shares of our common stock (the “Stock Warrants”) with an exercise price of $ 26.68 per warrant as an additional incentive for Comcast to convert customer accounts onto our solutions based on various milestones. As of June 30, 2024 , 1.0 million Stock Warrants remained issued and unvested. The Stock Warrants had a ten-year term and expired in July 2024. Stock-Based Awards. During the six months ended June 30, 2024 we granted restricted stock awards to key members of management in the form of: (i) performance-based awards of approximately 155,000 restricted common stock shares, which vest in the first quarter of 2026 upon meeting certain pre-established financial performance objectives over a two-year performance period; and (ii) market-based awards of approximately 52,000 restricted common stock shares, which vest in the first quarter of 2027 upon meeting a relative total shareholder return performance achievement tier. Certain of these awards may vest (i.e., vesting accelerates) upon the involuntary termination of employment or a change in control (as defined) and the subsequent involuntary termination of employment. During the six months ended June 30, 2024 , we also granted restricted stock awards to key members of management in the form of time-based awards of approximately 473,000 restricted common stock shares, which vest annually over three years with no restrictions other than the passage of time. Certain of these awards may vest (i.e., vesting accelerates) upon the involuntary termination of employment, a change in control (as defined) and the subsequent involuntary termination of employment, or death. We recorded stock-based compensation expense for the second quarters of 2024 and 2023 of $ 8.6 million and $ 7.6 million, respectively, and for the six months ended June 30, 2024 and 2023 of $ 16.4 million and $ 14.1 million, respectively .

Accounting Policies [Abstract]
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements. The preparation of our Financial Statements requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our Financial Statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Revenue	Revenue. The majority of our future revenue is related to our customer contracts for our SaaS and related solutions that include variable consideration dependent upon a series of monthly volumes and/or daily usage of services and have contractual terms ending from 2024 through 2036 . Our customer contracts may include guaranteed minimums and fixed monthly or annual fees. As of June 30, 2024 , our aggregate amount of the transaction price allocated to the remaining performance obligations was approximately $ 1.4 billion, which is made up of fixed fee consideration and guaranteed minimums expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). We expect to recognize approximately 75 % of this amount by the end of 2026 , with the remaining amount recognized by the end of 2036 . We have excluded from this amount variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied. The nature, amount, timing, and uncertainty of our revenue and how revenue and cash flows are affected by economic factors is most appropriately depicted by revenue type, geographic region, and customer vertical. Revenue by type for the quarters and six months ended June 30, 2024 and 2023 was as follows (in thousands): Quarter Ended Six Months Ended June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 SaaS and related solutions $ 262,658 $ 255,600 $ 524,353 $ 513,476 Software and services 14,681 18,766 37,075 49,657 Maintenance 12,979 11,961 24,025 21,933 Total revenue $ 290,318 $ 286,327 $ 585,453 $ 585,066 We use the location of the customer as the basis of attributing revenue to geographic regions. Revenue by geographic region for the quarters and six months ended June 30, 2024 and 2023, as a percentage of our total revenue, was as follows: Quarter Ended Six Months Ended June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Americas (principally the U.S.) 89 % 87 % 87 % 85 % Europe, Middle East, and Africa 6 % 9 % 8 % 11 % Asia Pacific 5 % 4 % 5 % 4 % Total revenue 100 % 100 % 100 % 100 % We generate our revenue primarily from the global communications markets; however, we serve an expanding group of customers in other markets including retail, financial services, healthcare, insurance, and government entities. Revenue by customer vertical for the quarters and six months ended June 30, 2024 and 2023, as a percentage of our total revenue, was as follows: Quarter Ended Six Months Ended June 30, 2024 June 30, 2023 June 30, 2024 June 30, 2023 Broadband/Cable/Satellite 53 % 54 % 52 % 53 % Telecommunications 16 % 18 % 17 % 19 % Other 31 % 28 % 31 % 28 % Total revenue 100 % 100 % 100 % 100 % Deferred revenue recognized during the quarters ended June 30, 2024 and 2023 was $ 10.7 million and $ 11.3 million, respectively. Deferred revenue recognized during the six months ended June 30, 2024 and 2023 was $ 29.8 million and $ 31.5 million, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less as of the date of purchase to be cash equivalents. As of June 30, 2024 and December 31, 2023, our cash equivalents consist primarily of institutional money market funds and time deposits held at major banks. For the cash and cash equivalents denominated in foreign currencies and/or located outside the U.S., we do not anticipate any material amounts being unavailable for use in running our business, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls and potential negative economic consequences. Restricted Cash. Restricted cash includes cash that is legally or contractually restricted, as well as our settlement and merchant reserve assets (discussed below). The nature of the restrictions on our settlement and merchant reserve assets consists of contractual restrictions with the merchants and restrictions arising from our policy and intention. It has historically been our policy to segregate settlement and merchant reserve assets from our operating cash balances and our intention is to continue to do so. As of June 30, 2024 and December 31, 2023, we had $ 3.1 million and $ 2.9 million, respectively, of restricted cash that mainly serves to collateralize bank and performance guarantees included in other current and non-current assets in our unaudited Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”).
Settlement and Merchant Reserve Assets and Liabilities	Settlement and Merchant Reserve Assets and Liabilities. Settlement assets and settlement liabilities represent cash collected on behalf of merchants via payments processing services which is held for an established holding period until settlement with the customer. The holding period is generally one to four business days depending on the payment model and contractual terms with the customer. During the holding period, cash is subject to restriction and segregation based on the nature of our custodial relationship with the merchants. Should we fail to remit these funds to our merchants, the merchant's sole recourse for payment would be against us. These rights and obligations are set forth in the contracts between us and the merchants. Settlement assets are held with various major financial institutions and a corresponding liability is recorded for the amounts owed to the customer. At any given time, there may be differences between the cash held and the corresponding liability due to the timing of operating-related cash transfers. Merchant reserve assets/liabilities represent deposits collected from merchants to mitigate our risk of loss due to nonperformance of settlement obligations initiated by those merchants using our payments processing services, or non-payment by customers for services rendered by us. We perform a credit risk evaluation on each customer based on multiple criteria, which provides the basis for the deposit amount required for each merchant. For the duration of our relationship with each merchant, we hold their reserve deposits with major financial institutions. We hold these funds in separate accounts, which are offset by corresponding liabilities. The following table summarizes our settlement and merchant reserve assets and liabilities as of the indicated periods (in thousands): June 30, 2024 December 31, 2023 Assets Liabilities Assets Liabilities Settlement assets/liabilities $ 216,485 $ 214,067 $ 260,712 $ 259,825 Merchant reserve assets/liabilities 15,569 15,569 13,987 13,992 Total $ 232,054 $ 229,636 $ 274,699 $ 273,817
Financial Instruments	Financial Instruments . Our financial instruments as of June 30, 2024 and December 31, 2023 include cash and cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, accounts payable, and debt. Due to their short maturities, the carrying amounts of cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, and accounts payable approximate their fair value. We have chosen not to record our debt at fair value, with changes recognized in earnings each reporting period. The following table indicates the carrying value and estimated fair value of our debt as of the indicated periods (in thousands): June 30, 2024 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value 2023 Convertible Notes (par value) $ 425,000 $ 396,483 $ 425,000 $ 428,506 2021 Credit Agreement (carrying value including 129,375 129,375 133,125 133,125 The fair value of our convertible notes was estimated based upon quoted market prices or recent sales activity, while the fair value of our credit agreement was estimated using a discounted cash flow methodology, both of which are considered Level 2 inputs. See Note 4 for a discussion regarding our debt.
Pillar Two	Pillar Two. Numerous foreign jurisdictions have enacted, or are in the process of enacting, legislation to adopt a minimum effective tax rate. Pillar Two, which was established by the Organization for Economic Co-operation and Development (OECD), generally provides for a 15% minimum effective tax rate for multinational enterprises in every jurisdiction in which they operate. The U.S. has not yet adopted Pillar Two, however, various other governments around the world have. These rules did not have a material impact on our taxes for the quarter and six months ended June 30, 2024 . We continue to monitor evolving tax legislation in the jurisdictions in which we operate.
Accounting Pronouncements Issued but Not Yet Effective	Accounting Pronouncements Issued but Not Yet Effective. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) , (“ASU 2023-07”), which enhances reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. ASU 2023-07 also requires disclosure of the title and position of the company’s Chief Operating Decision Maker (“CODM”) and how the CODM uses financial reporting to assess segment performance and allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires entities to disclose more detailed information about their effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures.
