Revenue Recognition [Abstract]
Revenue	Note 2. Revenue Revenue Recognition The Company manages highly-customized data and materials to enable filings with the SEC on behalf of its customers as well as performs tagging of documents using Inline eXtensible Business Reporting Language (“iXBRL”) and other services. Clients are provided with EDGAR filing services, iXBRL compliance services and translation, editing, interpreting, proof-reading and multilingual typesetting services, among other services. The Company provides software solutions to public and private companies, mutual funds and other regulated investment firms to serve their regulatory and compliance needs, including ActiveDisclosure, Arc Suite and Venue, and provides digital document creation, online content management and print and distribution solutions. Revenue is recognized upon transfer of control of promised services or products to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services or products. The Company’s services include software solutions and tech-enabled services whereas the Company’s products are comprised of print and distribution offerings. The Company’s arrangements with customers often include promises to transfer multiple services or products to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately requires significant judgment. Certain customer arrangements have multiple performance obligations as certain promises are both capable of being distinct and are distinct within the context of the contract. Other customer arrangements have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, and therefore is not distinct. Revenue for the Company’s tech-enabled services, software solutions and print and distribution offerings is recognized either over time or at a point in time, as further disclosed in the Annual Report. Disaggregation of Revenue The following table disaggregates revenue between tech-enabled services, software solutions and print and distribution by reportable segment: Three Months Ended March 31, 2024 2023 Tech-enabled Services Software Solutions Print and Distribution Total Tech-enabled Services Software Solutions Print and Distribution Total Capital Markets - Software Solutions $ — $ 53.0 $ — $ 53.0 $ — $ 43.7 $ — $ 43.7 Capital Markets - Compliance and Communications Management 66.0 — 25.1 91.1 60.7 — 33.4 94.1 Investment Companies - Software Solutions — 27.3 — 27.3 — 26.4 — 26.4 Investment Companies - Compliance and Communications Management 16.9 — 15.1 32.0 17.7 — 16.7 34.4 Total net sales $ 82.9 $ 80.3 $ 40.2 $ 203.4 $ 78.4 $ 70.1 $ 50.1 $ 198.6 Unbilled Receivables and Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in contract assets, unbilled receivables or contract liabilities. Contract assets represent revenue recognized for performance obligations completed before an unconditional right to payment exists and therefore invoicing has not yet occurred. The Company generally estimates contract assets based on the historical selling price adjusted for its current experience and expected resolution of the variable consideration of the completed performance obligation. When the Company’s contracts contain variable consideration, the variable consideration is recognized only to the extent that it is probable that a significant revenue reversal will not occur in a future period. As a result, the estimated revenue and contract assets may be constrained until the uncertainty associated with the variable consideration is resolved, which generally occurs in less than one year. Determining whether there will be a significant revenue reversal in the future and the determination of the amount of the constraint requires significant judgment. Contract assets were $ 24.2 million and $ 16.3 million at March 31, 2024 and December 31, 2023, respectively. Generally, the contract assets balance is impacted by the recognition of additional revenue, amounts invoiced to customers and changes in the level of constraint applied to variable consideration. Amounts recognized as revenue exceeded the estimates for performance obligations satisfied in previous periods by approximately $ 11.0 million and $ 11.7 million for the three months ended March 31, 2024 and 2023, respectively, primarily due to changes in the Company’s estimate of variable consideration and the application of the constraint. Unbilled receivables are recorded when there is an unconditional right to payment and invoicing has not yet occurred. The Company estimates the value of unbilled receivables based on a combination of historical customer selling price and management’s assessment of realizable selling price. Unbilled receivables were $ 50.5 million and $ 21.6 million at March 31, 2024 and December 31, 2023, respectively. Unbilled receivables and contract assets are included in receivables, less allowances for expected losses on the Unaudited Condensed Consolidated Balance Sheets. Contract liabilities consist of deferred revenue and progress billings, which are included in accrued liabilities on the Unaudited Condensed Consolidated Balance Sheets. The Company recognized $ 19.1 million and $ 17.7 million of revenue during the three months ended March 31, 2024 and 2023, respectively, that was included in the deferred revenue balances at the beginning of the respective periods. Changes in contract liabilities were as follows: March 31, 2024 2023 Balance, beginning of year $ 46.8 $ 46.1 Deferral of revenue 41.2 41.5 Revenue recognized ( 37.0 ) ( 34.6 ) Balance, end of period $ 51.0 $ 53.0 Most of the Company's contracts with significant remaining performance obligations have an initial expected duration of one year or less. As of March 31, 2024, the future estimated revenue related to unsatisfied or partially satisfied performance obligations under contracts with an original contractual term in excess of one year was approximately $ 121 million, of which approximately 55 % is expected to be recognized as revenue over the succeeding twelve months , and the remainder recognized thereafter.

On May 11, 2023, the Company entered into the first amendment to the Amended and Restated Credit Agreement to change the reference rate from LIBOR, which ceased being published on June 30, 2023, to the Secured Overnight Financing Rate (“SOFR”) for both the Term Loan A Facility and the Revolving Facility. The SOFR interest rate was effective for the Revolving Facility and the Term Loan A on May 30, 2023 and June 12, 2023, respectively. No other significant terms of the Amended and Restated Credit Agreement were amended. The Amended and Restated Credit Agreement contains a number of covenants, including a minimum Interest Coverage Ratio and the Consolidated Net Leverage Ratio, as defined in and calculated pursuant to the Credit Agreement, that, in part, restrict the Company’s ability to incur additional indebtedness, create liens, engage in mergers and consolidations, make restricted payments and dispose of certain assets. The Credit Agreement generally allows annual dividend payments of up to $ 20.0 million in the aggregate . Term Loan A Facility —The unpaid principal amount of the Term Loan A Facility is due and payable in full on May 27, 2026. Voluntary prepayments of the Term Loan A Facility are permitted at any time without premium or penalty. The weighted-average interest rate on borrowings under the Term Loan A Facility was 7.4 % and 6.0 % for the three months ended March 31, 2024 and 2023, respectively. The fair value of the Term Loan A Facility was $ 124.5 million and $ 124.1 million as of March 31, 2024 and December 31, 2023, respectively, and was determined to be Level 2 under the fair value hierarchy. Revolving Facility —As of March 31, 2024, there were $ 80.0 million of borrowings outstanding under the Revolving Facility. As of December 31, 2023 , there were no borrowings outstanding under the Revolving Facility. The weighted average interest rate on borrowings under the Revolving Facility was 7.9 % and 6.9 % for the three months ended March 31, 2024 and 2023, respectively. The fair value of the Company's borrowings under the Revolving Facility is classified as Level 2 under the fair value hierarchy and approximated its carrying value as of March 31, 2024, as the Revolving Facility carries a variable rate of interest reflecting current market rates.

The fair value of PSUs granted prior to 2024 was based on the Company's stock price on the grant date. The 2024 PSUs include a market condition related to the performance of the Company's stock price relative to a peer group, or relative total shareholder return (“TSR” ) modifier, which can affect the number of shares ultimately issued to grantees at the end of the three-year performance period. The grant date fair value of the 2024 PSUs was determined based on a Monte Carlo valuation model. The total potential payout for the 2024 PSUs is payable upon the achievement of certain established performance targets and can also be impacted by the TSR modifier, resulting in a range from zero to 564 thousand shares.

Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which requires that an entity disclose consistent categories and greater disaggregation of significant expenses by reportable segment, information regarding the chief operating decision maker (“CODM”) and how the CODM uses the reported measures in assessing segment performance and deciding how to allocate resources, among other amendments that expand segment reporting disclosures. ASU 2023-07 also requires that an entity disclose all information about a reportable segment’s profit or loss and assets currently required annually by FASB Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting, in interim periods. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on its disclosures to the Unaudited Condensed Consolidated Financial Statements. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires that an entity disclose consistent categories and greater disaggregation of information in the income tax rate reconciliation, income taxes paid disaggregated by jurisdiction, among other amendments that expand income tax disclosures. The standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted.

Revenue Recognition	Revenue Recognition The Company manages highly-customized data and materials to enable filings with the SEC on behalf of its customers as well as performs tagging of documents using Inline eXtensible Business Reporting Language (“iXBRL”) and other services. Clients are provided with EDGAR filing services, iXBRL compliance services and translation, editing, interpreting, proof-reading and multilingual typesetting services, among other services. The Company provides software solutions to public and private companies, mutual funds and other regulated investment firms to serve their regulatory and compliance needs, including ActiveDisclosure, Arc Suite and Venue, and provides digital document creation, online content management and print and distribution solutions. Revenue is recognized upon transfer of control of promised services or products to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services or products. The Company’s services include software solutions and tech-enabled services whereas the Company’s products are comprised of print and distribution offerings. The Company’s arrangements with customers often include promises to transfer multiple services or products to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately requires significant judgment. Certain customer arrangements have multiple performance obligations as certain promises are both capable of being distinct and are distinct within the context of the contract. Other customer arrangements have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, and therefore is not distinct. Revenue for the Company’s tech-enabled services, software solutions and print and distribution offerings is recognized either over time or at a point in time, as further disclosed in the Annual Report. The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in contract assets, unbilled receivables or contract liabilities. Contract assets represent revenue recognized for performance obligations completed before an unconditional right to payment exists and therefore invoicing has not yet occurred. The Company generally estimates contract assets based on the historical selling price adjusted for its current experience and expected resolution of the variable consideration of the completed performance obligation. When the Company’s contracts contain variable consideration, the variable consideration is recognized only to the extent that it is probable that a significant revenue reversal will not occur in a future period. As a result, the estimated revenue and contract assets may be constrained until the uncertainty associated with the variable consideration is resolved, which generally occurs in less than one year. Determining whether there will be a significant revenue reversal in the future and the determination of the amount of the constraint requires significant judgment. Unbilled receivables are recorded when there is an unconditional right to payment and invoicing has not yet occurred. The Company estimates the value of unbilled receivables based on a combination of historical customer selling price and management’s assessment of realizable selling price.
Lessee Leases Policy	The Company has operating leases for certain service centers, office space and equipment as well as finance leases primarily related to certain information technology equipment.
Restructuring	The Company records restructuring charges associated with management-approved restructuring plans, which could include the elimination of job functions, closure or relocation of facilities, reorganization of operations, changes in management structure, workforce reductions or other actions. Restructuring charges may include ongoing and enhanced termination benefits related to employee separations, contract termination costs and other related costs associated with exit or disposal activities. Restructuring charges for employee terminations include management’s estimate as to the timing and amount of severance and actual results could differ from estimates.
Earnings per Share	Net earnings per basic share is calculated by dividing net earnings by the weighted average number of common shares outstanding for the period. Net earnings per diluted share is computed using the weighted average number of common and potentially dilutive shares outstanding during the period, including stock options, restricted stock units (“RSUs”), performance share units (“PSUs”) and restricted stock, using the treasury stock method

[1] The 2024 PSUs contain five performance periods, including three annual performance periods and two three-year cumulative performance periods. Amounts represent estimated attainment and estimated PSUs. The PSU awards granted in 2023 and 2022 consist of four performance periods, including three annual performance periods and one three-year cumulative performance period. Amounts represent actual attainment and actual PSUs earned as the performance period is complete. Attainment percentage does not include the TSR modifier that is determined at the end of the three-year performance period and applied to PSUs that are earned based on the achievement of the service and performance conditions. Expense for the cumulative performance/service period is recognized at 100 % of the estimated attainment until the attainment expected by the end of the cumulative three-year performance period can be reasonably estimated, which generally occurs at the end of the second service year.
