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 SaaS and related solutions customer contracts 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 March 31, 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 over 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 ended March 31, 2024 and 2023 was as follows (in thousands): Quarter Ended March 31, 2024 March 31, 2023 SaaS and related solutions $ 261,695 $ 257,876 Software and services 22,394 30,891 Maintenance 11,046 9,972 Total revenue $ 295,135 $ 298,739 We use the location of the customer as the basis of attributing revenue to geographic regions. Revenue by geographic region for the quarters ended March 31, 2024 and 2023, as a percentage of our total revenue, was as follows: Quarter Ended March 31, 2024 March 31, 2023 Americas (principally the U.S.) 86 % 84 % Europe, Middle East, and Africa 9 % 12 % Asia Pacific 5 % 4 % Total revenue 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 ended March 31, 2024 and 2023, as a percentage of our total revenue, was as follows: Quarter Ended March 31, 2024 March 31, 2023 Broadband/Cable/Satellite 51 % 52 % Telecommunications 19 % 20 % Other 30 % 28 % Total revenue 100 % 100 % Deferred revenue as of December 31, 2023 and 2022 recognized during the quarters ended March 31, 2024 and 2023 was $ 19.1 million and $ 20.2 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 March 31, 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 both March 31, 2024 and December 31, 2023 , we had $ 2.9 million 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): March 31, 2024 December 31, 2023 Assets Liabilities Assets Liabilities Settlement assets/liabilities $ 178,679 $ 177,207 $ 260,712 $ 259,825 Merchant reserve assets/liabilities 14,283 14,291 13,987 13,992 Total $ 192,962 $ 191,498 $ 274,699 $ 273,817 Financial Instruments . Our financial instruments as of March 31, 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): March 31, 2024 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value 2023 Convertible Notes (par value) $ 425,000 $ 420,856 $ 425,000 $ 428,506 2021 Credit Agreement (carrying value including 131,250 131,250 133,125 133,125 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 percent 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 three months ended March 31, 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. |
