Accounting Policies [Abstract]
Accounting Standards and Significant Accounting Policies	Accounting Standards and Significant Accounting Policies SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES There have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 22, 2023, that have had a material impact on our condensed consolidated financial statements and related notes. See Recently Adopted Accounting Pronouncements below. REVENUE RECOGNITION Nature of Products and Services The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. We earn the majority of our revenues from subscription-based services and post-contract customer support (“PCS” or “maintenance”). Other sources of revenue are professional services, software licenses and royalties, and hardware and other. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We determine revenue recognition through the following steps: •Identification of the contract, or contracts, with a customer •Identification of the performance obligations in the contract •Determination of the transaction price •Allocation of the transaction price to the performance obligations in the contract •Recognition of revenue when, or as, we satisfy a performance obligation Subscriptions revenue consists of revenue derived from our software as a service ("SaaS") arrangements and transaction-based fees primarily related to digital government services and payment processing. We also provide electronic document filing solutions (“e-filing”) that simplify the filing and management of court related documents for courts and law offices. E-filing revenue is derived from transaction fees and fixed fee arrangements. For transaction-based fees, we have the right to charge the customer an amount that directly corresponds with the value to the customer of our performance to date. Therefore, we recognize revenue for these services over time based on the amount billable to the customer in accordance with the 'as invoiced' practical expedient in ASC 606-10-55-18. In some cases, we are paid on a fixed fee basis and recognize the revenue ratably over the contractual period. Typically, the structure of our arrangements does not give rise to variable consideration. However, in those instances whereby variable consideration exists, we include in our estimates, additional revenue for variable consideration when we believe we have an enforceable right, the amount can be estimated reliably and its realization is probable. Other software arrangements with customers contain multiple performance obligations that range from software licenses, installation, training, and consulting to software modification and customization to meet specific customer needs (services), hosting, and PCS. For these contracts, we account for individual performance obligations separately when they are distinct. We evaluate whether separate performance obligations can be distinct or should be accounted for as one performance obligation. Arrangements that include professional services, such as training or installation, are evaluated to determine whether those services are highly interdependent or interrelated to the product’s functionality. The transaction price is allocated to the distinct performance obligations on a relative standalone selling price (“SSP”) basis. We determine the SSP based on our overall pricing objectives, taking into consideration market conditions and other factors, including the value of our contracts, the applications sold, customer demographics, and the number and types of users within our contracts. For arrangements that involve significant production, modification, or customization of the software, or where professional services otherwise cannot be considered distinct, we recognize revenue as control is transferred to the customer over time using progress-to-completion methods. Depending on the contract, we measure progress-to-completion primarily using labor hours incurred, or value added. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent. Revenue is recognized net of allowances for sales adjustments and any taxes collected from customers, which are subsequently remitted to governmental authorities. Refer to Note 4, “Disaggregation of Revenue,” for further information, including the economic factors that affect the nature, amount, timing, and uncertainty of revenue and cash flows of our various revenue categories. Contract Balances: Accounts receivable and allowance for losses and sales adjustments Timing of revenue recognition may differ from the timing of invoicing to customers. We record an unbilled receivable when revenue is recognized prior to invoicing, or deferred revenue when invoicing occurs prior to revenue recognition. For multi-year agreements, we generally invoice customers annually at the beginning of each annual coverage period. We record an unbilled receivable related to revenue recognized for on-premises licenses as we have an unconditional right to invoice and receive payment in the future related to those licenses. At September 30, 2023, and December 31, 2022, total current and long-term accounts receivable, net of allowance for losses and sales adjustments, was $633.7 million and $585.5 million, respectively. We have recorded unbilled receivables of $130.5 million and $135.4 million at September 30, 2023 and December 31, 2022, respectively. Included in unbilled receivables are retention receivables of $8.7 million and $8.6 million at September 30, 2023 and December 31, 2022, respectively, which become payable upon the completion of the contract or completion of our fieldwork and formal hearings. Unbilled receivables expected to be collected within one year have been included with accounts receivable, current portion in the accompanying condensed consolidated balance sheets. Unbilled receivables and retention receivables expected to be collected past one year have been included with accounts receivable, long-term portion in the accompanying condensed consolidated balance sheets. We maintain allowances for losses and sales adjustments, which are recorded against revenue at the time the loss is incurred. Since most of our clients are domestic governmental entities, we rarely incur a credit loss resulting from the inability of a client to make required payments. Events or changes in circumstances that indicate the carrying amount for the allowances for losses and sales adjustments may require revision include, but are not limited to, managing our client’s expectations regarding the scope of the services to be delivered and defects or errors in new versions or enhancements of our software products. Our allowance for losses and sales adjustments of $17.0 million and $14.8 million at September 30, 2023 and December 31, 2022, respectively, does not include provisions for credit losses. Because we rarely experience credit losses with our clients, we have not recorded a material reserve for credit losses. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill We assess goodwill for impairment annually, or more frequently whenever events or changes in circumstances indicate its carrying value may not be recoverable. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value before applying the quantitative assessment described below. When testing goodwill for impairment quantitatively, we first compare the fair value of each reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds the fair value of that reporting unit, an impairment loss is recognized. The fair values calculated in our impairment tests are determined using discounted cash flow models involving several assumptions (Level 3 inputs). The assumptions that are used are based upon what we believe a hypothetical marketplace participant would use in estimating fair value. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. We evaluate the reasonableness of the fair value calculations of our reporting units by comparing the total of the fair value of all of our reporting units to our total market capitalization. During the fourth quarter of 2022, as part of our annual impairment test as of October 1, we performed qualitative assessments for all reporting units except for reporting units that do not have significant excess fair value over carrying value. As a result of these qualitative assessments, we determined that it was more likely than not that the fair value exceeded the carrying value; therefore, we did not perform a Step 1 quantitative impairment test. We performed quantitative assessments for the reporting units containing the recently acquired data and insights, digital government and payments solutions, and development platform solutions reporting units and concluded no impairment existed as of our annual assessment date. Approximately $1.7 billion, or 70%, of total goodwill as of December 31, 2022, related to these reporting units, which, as a result of the recency of these acquisitions, do not have significant excess fair values over carrying values. Our annual goodwill impairment analysis did not result in an impairment charge. For the nine months ended September 30, 2023, we have not recorded any impairment to goodwill because no triggering events or change in circumstances indicating a potential impairment had occurred as of period-end. Determining the fair value of our reporting units involves the use of significant estimates and assumptions and considerable management judgment. We base our fair value estimates on assumptions we believe to be reasonable at the time, but such assumptions are subject to inherent uncertainty. Changes in market conditions or other factors outside of our control could cause us to change key assumptions and our judgment about a reporting unit’s prospects. Similarly, in a specific period, a reporting unit could significantly underperform relative to its historical or projected future operating results. Either situation could result in a meaningfully different estimate of the fair value of our reporting units, and a consequent future impairment charge.
