Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The financial data presented herein should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the Company's latest Annual Report. In the opinion of management, the financial data presented includes all adjustments necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented. Results of interim periods should not be considered indicative of the results for the full year. Significant Accounting Policies Use of Estimates— The preparation of financial statements in conformity with GAAP requires the extensive use of management’s estimates and assumptions that affect the reported amounts of assets and liabilities as well as disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The Company’s significant accounting policies and critical accounting estimates are disclosed in the Annual Report. Allowances for Expected Losses — Transactions affecting the current expected credit loss (“CECL”) reserve during the three months ended March 31, 2023 and 2022 were as follows: March 31, 2023 2022 Balance, beginning of year (a) $ 17.1 $ 12.7 Provisions charged to expense 3.6 2.3 Write-offs, reclassifications and other ( 2.6 ) ( 0.5 ) Balance, end of period (a) $ 18.1 $ 14.5 (a) As of March 31, 2023, the CECL reserve balance is comprised of a $ 17.2 million provision for accounts receivable and a $ 0.9 million provision for unbilled receivables and contract assets. As of December 31, 2022, the CECL reserve balance was comprised of a $ 16.5 million provision for accounts receivable and a $ 0.6 million provision for unbilled receivables and contract assets. Assets Held for Sale —As of March 31, 2023 and December 31, 2022 , the Company had land held for sale with a carrying value of $ 2.6 million. On August 30, 2022, the Company entered into an agreement to sell the land for $ 13.0 million.

Software, net —Capitalized software development costs are amortized over their estimated useful life using the straight-line method, up to a maximum of three years . Amortization expense related to internally-developed software, excluding amortization expense related to other intangible assets, was $ 10.3 million and $ 8.9 million for the three months ended March 31, 2023 and 2022 , respectively. Investments — The carrying value of the Company’s investments in equity securities was $ 6.3 million and $ 8.5 million at March 31, 2023 and December 31, 2022, respectively. The Company measures its equity securities that do not have a readily determinable fair value at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company performs an assessment on a quarterly basis to determine whether triggering events for impairment exist and to identify any observable price changes. During the three months ended March 31, 2023, there were no events or changes in circumstances that suggested an impairment or an observable price change. During the three months ended March 31, 2023 , the Company sold an investment in an equity security and received proceeds of $ 11.8 million, including $ 8.9 million of cash and common stock of the acquiror. The sale resulted in a net realized gain of $ 6.7 million, which is included in investment and other income, net, on the Unaudited Condensed Consolidated Statements of Operations within Corporate. Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board issued Accounting Standards Update No. 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, as if it had originated the contracts, rather than at fair value. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted the standard prospectively on January 1, 2023. The adoption of this standard did not have a material impact on the Company's Unaudited Condensed Consolidated Financial Statements.

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 eXtensible Business Reporting Language (“XBRL”) and other services. Clients are provided with EDGAR filing services, XBRL 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 Venue, Arc Suite, ActiveDisclosure, among others, 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, 2023 2022 Tech-enabled Services Software Solutions Print and Distribution Total Tech-enabled Services Software Solutions Print and Distribution Total Capital Markets - Software Solutions $ — $ 43.7 $ — $ 43.7 $ — $ 44.7 $ — $ 44.7 Capital Markets - Compliance and Communications Management 60.7 — 33.4 94.1 71.1 — 32.5 103.6 Investment Companies - Software Solutions — 26.4 — 26.4 — 25.1 — 25.1 Investment Companies - Compliance and Communications Management 17.7 — 16.7 34.4 20.6 — 17.0 37.6 Total net sales $ 78.4 $ 70.1 $ 50.1 $ 198.6 $ 91.7 $ 69.8 $ 49.5 $ 211.0 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 $ 38.9 million and $ 20.1 million at March 31, 2023 and December 31, 2022, 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 $ 11.7 million and $ 3.2 million for the three months ended March 31, 2023 and 2022, 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 $ 52.2 million and $ 33.2 million at March 31, 2023 and December 31, 2022, respectively. Unbilled receivables and contract assets are included in receivables, less allowances for expected losses on the Unaudited Condensed Consolidated Balance Sheets. 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, 2023 , 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 $ 120.1 million, of which approximately 46 % is expected to be recognized as revenue over the succeeding twelve months , and the remainder recognized thereafter. 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 $ 17.7 million and $ 16.1 million of revenue during the three months ended March 31, 2023 and 2022, respectively, that was included in the deferred revenue balances at the beginning of the respective periods. Changes in contract liabilities were as follows: Balance at January 1, 2023 $ 46.1 Deferral of revenue 41.5 Revenue recognized ( 34.6 ) Balance at March 31, 2023 $ 53.0 Balance at January 1, 2022 $ 36.0 Deferral of revenue 34.2 Revenue recognized ( 27.9 ) Balance at March 31, 2022 $ 42.3

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.
