Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Consolidation The consolidated financial statements and accompanying notes have been prepared in U.S. dollars and in accordance with GAAP. Accounting Policies The Company’s consolidated financial statements are prepared in accordance with GAAP, which require us to select accounting policies and make estimates that affect the reported amount of assets, liabilities, revenues, and expenses, and the related disclosure of contingent assets and contingent liabilities. Actual results could differ materially from these estimates. Information on other accounting policies and methods that we use in the preparation of our consolidated financial statements are included, where applicable, in their respective footnotes that follow. Below is a discussion of accounting policies and methods used in our consolidated financial statements that are not presented within other footnotes.
Consolidation	The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The Company is party to joint ventures, which are accounted for using the equity method. All intercompany accounts and transactions have been eliminated in consolidation. Gains and losses resulting from foreign currency transactions denominated in currencies other than the functional currency are included in Other income (expense), net in the consolidated statements of operations. The assets and liabilities of foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date, and revenue and expense amounts are translated at average rates during the period. Foreign currency translation adjustments are recorded as a component of Other comprehensive income (loss), net of taxes in the consolidated statements of comprehensive income.
Reclassification	Reclassifications Certain reclassifications of prior period amounts have been made to conform to the current period presentation.
Segment	Segment — Reportable segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the CODM to allocate resources and assess performance. The Company defines its CODM to be its chief executive officer. The chief executive officer reviews the financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating the Company’s financial performance. Accordingly, the Company has determined it operates and manages its business in a single reportable segment, the development and marketing of computer software and related services. The Company markets its products and services through the Company’s offices in the U.S. and its wholly‑owned branches and subsidiaries internationally.
Cost of Revenues and Revenues from Contract with Customer	Cost of Revenues — Cost of subscriptions and licenses expenses primarily include headcount‑related costs, as well as depreciation of property and equipment and amortization of capitalized software costs associated with servicing software subscriptions, amortization of intangible assets associated with acquired software and technology, channel partner compensation for providing sales coverage to users, as well as cloud‑related costs incurred for servicing the Company’s customers using cloud provisioned solutions and the Company’s license administration platform. Cost of services expenses primarily include headcount‑related costs, as well as depreciation of property and equipment and amortization of capitalized software costs, used for providing training, implementation, configuration, and customization services to customers. Nature of Products and Services The Company recognizes revenue upon the transfer of promised goods or services to customers in an amount that reflects the expected consideration received in exchange for those goods or services. The Company generates revenues from subscriptions, perpetual licenses, and services. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. The contract costs are amortized based on the economic life of the goods and services to which the contract costs relate. The Company has determined that costs under certain sales incentive programs meet the requirements to be capitalized. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include the Company’s internal sales force compensation program and certain channel partner sales incentive programs for which the annual compensation is commensurate with annual sales activities. Subscriptions Enterprise Subscriptions The Company provides enterprise subscription offerings, which provide its enterprise accounts with complete and unlimited global access to the Company’s comprehensive portfolio of solutions. E365 subscriptions require a CSS as described below and are charged to accounts primarily based upon daily usage. The daily usage fee includes a term license component, SELECT maintenance and support, hosting, and Success Blueprints, which are designed to achieve business outcomes through more efficient and effective use of the Company’s software. E365 revenues are recognized based upon usage incurred by the account. Usage is primarily defined as distinct user access on a daily basis. E365 subscriptions can contain quarterly usage floors or collars. The term of E365 subscriptions aligns with calendar quarters and revenue is recognized based on actual usage. Alternatively, enterprise license subscriptions (“ELS”) provide access for a prepaid fee, which is based on the account’s usage of software in the preceding year, to effectively create a fee‑certain consumption‑based arrangement. ELS contain a term license component, SELECT maintenance and support, and performance consulting days. The SELECT maintenance and support benefits under ELS do not include a portfolio balancing performance obligation. Revenue is allocated to the various performance obligations based on their respective SSP. Revenue allocated to the term license component is recognized upon delivery at the start of the subscription term while revenues for the SELECT maintenance and support and the performance consulting days are recognized as delivered over the subscription term. Billings in advance are recorded as Deferred revenues in the consolidated balance sheets. SELECT Subscriptions The Company provides prepaid annual recurring subscriptions that accounts (which are based on distinct contractual and billing relationships with the Company, where affiliated entities of a single parent company may each have an independent account with the Company) can elect to add to a new or previously purchased perpetual license. SELECT provides accounts with benefits, including upgrades, comprehensive technical support, pooled licensing benefits, annual portfolio balancing exchange rights, learning benefits, certain Azure‑based cloud collaboration services, mobility advantages, and access to other available benefits. SELECT subscriptions revenues are recognized as distinct performance obligations are satisfied. The performance obligations within the SELECT offering, outside of the portfolio balancing exchange right, are concurrently delivered and have the same pattern of recognition. These performance obligations are accounted for ratably over the term as a single performance obligation. Term License Subscriptions The Company provides annual, quarterly, and monthly term licenses for its software products. Term license subscriptions contain a term license component and SELECT maintenance and support. Revenue is allocated to the various performance obligations based on their SSP. Annual term licenses (“ATL”) are generally prepaid annually for named user access to specific products and include the Company’s Virtuoso subscriptions sold via the Company’s Virtuosity eStore for practitioner licenses. Virtuoso subscriptions are bundles with customizable training and expert consultation administered through “keys” or credits. Quarterly term license (“QTL”) subscriptions allow accounts to pay quarterly in arrears for license usage that is beyond their prepaid subscriptions. Monthly term license (“MTL”) subscriptions are identical to QTL subscriptions, except for the term of the license, and the manner in which they are monetized. MTL subscriptions require a CSS, which is described below. For ATL, revenue allocated to the term license component is recognized upon delivery at the start of the subscription term while revenue for the SELECT maintenance and support is recognized as delivered over the subscription term. For Virtuoso keys, revenue is recognized as services are delivered. Billings in advance are recorded as Deferred revenues in the consolidated balance sheets. For usage‑based QTL and MTL subscriptions, revenues are recognized based upon usage incurred by the account. Usage is defined as peak usage over the respective terms. The terms of QTL and MTL subscriptions align with calendar quarters and calendar months, respectively, and revenue is recognized based on actual usage. Visas are quarterly or annual term licenses enabling users to access specific project or enterprise information and entitles users to certain functionality of the Company’s ProjectWise and AssetWise systems. The Company’s standard offerings are usage based with monetization through the Company’s CSS program as described below. CSS is a program designed to streamline the procurement, administration, and payment process. The program requires an estimation of annual usage for CSS eligible offerings and a deposit of funds in advance. Actual consumption is monitored and invoiced against the deposit on a calendar quarter basis. CSS balances not utilized for eligible products or services may roll over to future periods or are refundable. Paid and unconsumed CSS balances are recorded in Accruals and other current liabilities in the consolidated balance sheets. Software and services consumed under CSS are recognized pursuant to the applicable revenue recognition guidance for the respective software or service and classified as subscriptions or services based on their respective nature. Perpetual Licenses Perpetual licenses may be sold with or without attaching a SELECT subscription. Historically, attachment and retention of the SELECT subscription has been high given the benefits of the SELECT subscription discussed above. Perpetual licenses revenues are recognized upon delivery of the license to the user. Services The Company provides professional services, including training, implementation, configuration, customization, and strategic consulting services. The Company performs projects on both a time and materials and a fixed fee basis. Certain of the Company’s fixed‑fee arrangements, including its Success Services offerings, are structured as subscription‑like, packaged offerings that are annually recurring in nature. Success Services are standard service offerings that provide a level of dedicated professional services above the standard technical support offered to all accounts as part of their SELECT or enterprise agreement. Revenues are recognized as services are performed. The Company primarily utilizes its direct internal sales force and also has arrangements through independent channel partners to promote and sell its products and subscriptions to end‑users. Channel partners are authorized to promote the sale of an authorized set of the Company’s products and subscriptions within an authorized geography under a Channel Partner Agreement. Significant Judgments and Estimates The Company’s contracts with customers may include promises to transfer licenses (perpetual or term‑based), maintenance, and services to a user. Judgment is required to determine if the promises are separate performance obligations, and if so, the allocation of the transaction price to each performance obligation. When an arrangement includes multiple performance obligations which are concurrently delivered and have the same pattern of transfer to the customer, the Company accounts for those performance obligations as a single performance obligation. For contracts with more than one performance obligation, the transaction price is allocated among the performance obligations in an amount that depicts the relative SSP of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately and needs to determine whether there is a discount that should be allocated based on the relative SSP of the various products and services. The Company’s SELECT agreement provides users with perpetual licenses a right to exchange software for other eligible perpetual licenses on an annual basis upon renewal. The Company refers to this option as portfolio balancing and has concluded that the portfolio balancing feature represents a material right resulting in the deferral of the associated revenue. Judgment is required to estimate the percentage of users who may elect to portfolio balance and considers inputs such as historical user elections. This feature is available once per term and must be exercised prior to the respective renewal term. The Company recognizes the associated revenue upon election or when the portfolio balancing right expires. This right is included in the initial and subsequent renewal terms and the Company reestablishes the revenue deferral for the material right upon the beginning of the renewal term.
Software Development Costs	Software Development Costs — The Company’s software development costs, including costs to develop software products or the software component of products to be sold, leased, or marketed to external accounts, before technological feasibility is reached, are included in Research and development in the consolidated statements of operations. Research and development expenses, which are generally expensed as incurred, primarily consist of headcount‑related costs. In general, technological feasibility is reached shortly before the release of such products. Under its Accelerated Commercial Development Program (“ACDP”) (the Company’s structured approach to an in‑house business incubator function), the Company capitalizes certain development costs related to certain projects once technological feasibility is established. Technological feasibility is established when a detailed program design has been completed and documented, the Company has established that the necessary skills, hardware, and software technology are available to produce the product, and there are no unresolved high‑risk development issues. Once the software is ready for its intended use, amortization is recorded over the software’s estimated useful life (generally three years).The Company evaluates the recoverability of capitalized ACDP costs whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable.
Advertising Expense	Advertising Expense — The Company expenses advertising costs as incurred.
Cash and Cash Equivalents	Cash and Cash Equivalents — The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. As of December 31, 2023 and 2022, all of the Company’s cash and cash equivalents consisted of money market funds and cash held in checking accounts maintained at various financial institutions. Cash equivalents are recorded at cost, which approximates fair value.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable primarily represent receivables from customers for products and services invoiced by the Company for which payment is outstanding and also unbilled revenues (see Note 3). Receivables are recorded at the invoiced amount and do not bear interest. The Company establishes an allowance for doubtful accounts for expected losses during the accounts receivable collection process. The allowance for doubtful accounts is presented separately in the consolidated balance sheets and reduces the accounts receivable balance to the net realizable value of the outstanding accounts receivable. The development of the allowance for doubtful accounts is based on an expected loss model which considers historical write‑off and recovery experience, aging trends affecting specific accounts, and general operational factors affecting all accounts. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company considers current economic trends and takes into account reasonable and supportable forecasts of future conditions when evaluating the adequacy of the allowance for doubtful accounts. If circumstances relating to specific customers change or unexpected changes occur in the general business environment, the Company’s estimate of the recoverability of receivables could be further adjusted.
Concentration of Credit Risk	Concentration of Credit Risk — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of its cash and cash equivalents, and receivables. To reduce credit risk, the Company performs ongoing credit evaluations of its customers and limits the amount of credit extended when deemed necessary. Generally, the Company requires no collateral from its customers. The Company maintains an allowance for potential credit losses, but historically has not experienced any significant losses related to individual customers or groups of customers in any particular industry or geographic region. The Company’s cash and cash equivalents are deposited with financial institutions and invested in money market funds that the Company believes are of high credit quality.
Recent Accounting Pronouncements	In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023‑09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023‑09”), which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. ASU 2023‑09 is effective for the Company for the annual reporting period beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2023‑09 on its consolidated financial statements and related disclosures. In November 2023, the FASB issued ASU No. 2023‑07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023‑07”), which expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how the Company’s CODM uses reported segment profit or loss information in assessing segment performance and allocating resources. ASU 2023‑07 is effective for the Company for the annual reporting period beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact of the adoption of ASU 2023‑07 on its consolidated financial statements and related disclosures. Recently Adopted Accounting Guidance In March 2020, the FASB issued ASU No. 2020‑04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020‑04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020‑04 applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform between March 12, 2020 and December 31, 2022. In December 2022, the FASB issued ASU No. 2022‑06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting by extending the sunset date of Topic 848 to December 31, 2024. The expedients and exceptions provided by these ASUs do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2024, except for hedging relationships existing as of December 31, 2024, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The Company adopted these ASUs during the second quarter of 2023 (see Note 10) and the adoption did not have a material impact on the Company’s consolidated financial statements.
Fair Value Measurements	The Company categorizes its assets and liabilities measured at fair value into a three‑level hierarchy, based on the priority of the inputs to the respective valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). An asset or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The fair value hierarchy consists of the following three levels: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on management’s own assumptions used to measure assets and liabilities at fair value. The Company’s financial instruments include cash equivalents, account receivables, certain other assets, accounts payable, accruals, certain other current and long‑term liabilities, and long‑term debt. Current Assets and Current Liabilities — In general, the carrying amounts reported on the Company’s consolidated balance sheets for current assets and current liabilities approximate their fair values due to the short‑term nature of those instruments. The following methods and assumptions were used by the Company in estimating its fair value measurements for Level 2 and Level 3 financial instruments as of December 31, 2023 and 2022: Acquisition Contingent Consideration — The fair value of these liabilities is generally determined using a cost or income approach and is measured based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions the Company believes would be made by a market participant. Interest Rate Swap — The fair value of the Company’s interest rate swap asset or liability is determined using an income approach and is measured based on the implied forward rates for the remaining term of the interest rate swap. The Company considers these valuation inputs to be Level 2 inputs in the fair value hierarchy. Long-Term Debt — The fair value of the Company’s borrowings under its Credit Facility approximated its carrying value based upon discounted cash flows at current market rates for instruments with similar remaining terms.The estimated fair value of the 2026 Notes and 2027 Notes is based on quoted market prices of the Company’s instrument in markets that are not active and are classified as Level 2 within the fair value hierarchy. Considerable judgment is necessary to interpret the market data and develop estimates of fair values. Accordingly, the estimates presented are not necessarily indicative of the amounts at which these instruments could be purchased, sold, or settled. Deferred Compensation Plan Liabilities — The fair value of deferred compensation plan liabilities, including the liability classified phantom investments in the DCP, are marked to market at the end of each reporting period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Accounting Policies

Basis of Presentation and Consolidation

The consolidated financial statements and accompanying notes have been prepared in U.S. dollars and in accordance with GAAP.

Accounting Policies

The Company’s consolidated financial statements are prepared in accordance with GAAP, which require us to select accounting policies and make estimates that affect the reported amount of assets, liabilities, revenues, and expenses, and the related disclosure of contingent assets and contingent liabilities. Actual results could differ materially from these estimates.

Information on other accounting policies and methods that we use in the preparation of our consolidated financial statements are included, where applicable, in their respective footnotes that follow. Below is a discussion of accounting policies and methods used in our consolidated financial statements that are not presented within other footnotes.

Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The Company is party to joint ventures, which are accounted for using the equity method. All intercompany accounts and transactions have been eliminated in consolidation.

Gains and losses resulting from foreign currency transactions denominated in currencies other than the functional currency are included in Other income (expense), net in the consolidated statements of operations. The assets and liabilities of foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date, and revenue and expense amounts are translated at average rates during the period. Foreign currency translation adjustments are recorded as a component of Other comprehensive income (loss), net of taxes in the consolidated statements of comprehensive income.

Reclassification

Reclassifications

Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

Segment

Segment — Reportable segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the CODM to allocate resources and assess performance. The Company defines its CODM to be its chief executive officer. The chief executive officer reviews the financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating the Company’s financial performance. Accordingly, the Company has determined it operates and manages its business in a single reportable segment, the development and marketing of computer software and related services. The Company markets its products and services through the Company’s offices in the U.S. and its wholly‑owned branches and subsidiaries internationally.

Cost of Revenues and Revenues from Contract with Customer

Cost of Revenues — Cost of subscriptions and licenses expenses primarily include headcount‑related costs, as well as depreciation of property and equipment and amortization of capitalized software costs associated with servicing software subscriptions, amortization of intangible assets associated with acquired software and technology, channel partner compensation for providing sales coverage to users, as well as cloud‑related costs incurred for servicing the Company’s customers using cloud provisioned solutions and the Company’s license administration platform. Cost of services expenses primarily include headcount‑related costs, as well as depreciation of property and equipment and amortization of capitalized software costs, used for providing training, implementation, configuration, and customization services to customers.

Nature of Products and Services

The Company recognizes revenue upon the transfer of promised goods or services to customers in an amount that reflects the expected consideration received in exchange for those goods or services. The Company generates revenues from subscriptions, perpetual licenses, and services.

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. The contract costs are amortized based on the economic life of the goods and services to which the contract costs relate. The Company has determined that costs under certain sales incentive programs meet the requirements to be capitalized. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include the Company’s internal sales force compensation program and certain channel partner sales incentive programs for which the annual compensation is commensurate with annual sales activities.

Subscriptions

Enterprise Subscriptions

The Company provides enterprise subscription offerings, which provide its enterprise accounts with complete and unlimited global access to the Company’s comprehensive portfolio of solutions. E365 subscriptions require a CSS as described below and are charged to accounts primarily based upon daily usage. The daily usage fee includes a term license component, SELECT maintenance and support, hosting, and Success Blueprints, which are designed to achieve business outcomes through more efficient and effective use of the Company’s software. E365 revenues are recognized based upon usage incurred by the account. Usage is primarily defined as distinct user access on a daily basis. E365 subscriptions can contain quarterly usage floors or collars. The term of E365 subscriptions aligns with calendar quarters and revenue is recognized based on actual usage. Alternatively, enterprise license subscriptions (“ELS”) provide access for a prepaid fee, which is based on the account’s usage of software in the preceding year, to effectively create a fee‑certain consumption‑based arrangement. ELS contain a term license component, SELECT maintenance and support, and performance consulting days. The SELECT maintenance and support benefits under ELS do not include a portfolio balancing performance obligation. Revenue is allocated to the various performance obligations based on their respective SSP. Revenue allocated to the term license component is recognized upon delivery at the start of the subscription term while revenues for the SELECT maintenance and support and the performance consulting days are recognized as delivered over the subscription term. Billings in advance are recorded as Deferred revenues in the consolidated balance sheets.

SELECT Subscriptions

The Company provides prepaid annual recurring subscriptions that accounts (which are based on distinct contractual and billing relationships with the Company, where affiliated entities of a single parent company may each have an independent account with the Company) can elect to add to a new or previously purchased perpetual license. SELECT provides accounts with benefits, including upgrades, comprehensive technical support, pooled licensing benefits, annual portfolio balancing exchange rights, learning benefits, certain Azure‑based cloud collaboration services, mobility advantages, and access to other available benefits. SELECT subscriptions revenues are recognized as distinct performance obligations are satisfied. The performance obligations within the SELECT offering, outside of the portfolio balancing exchange right, are concurrently delivered and have the same pattern of recognition. These performance obligations are accounted for ratably over the term as a single performance obligation.

Term License Subscriptions

The Company provides annual, quarterly, and monthly term licenses for its software products. Term license subscriptions contain a term license component and SELECT maintenance and support. Revenue is allocated to the various performance obligations based on their SSP. Annual term licenses (“ATL”) are generally prepaid annually for named user access to specific products and include the Company’s Virtuoso subscriptions sold via the Company’s Virtuosity eStore for practitioner licenses. Virtuoso subscriptions are bundles with customizable training and expert consultation administered through “keys” or credits. Quarterly term license (“QTL”) subscriptions allow accounts to pay quarterly in arrears for license usage that is beyond their prepaid subscriptions. Monthly term license (“MTL”) subscriptions are identical to QTL subscriptions, except for the term of the license, and the manner in which they are monetized. MTL subscriptions require a CSS, which is described below. For ATL, revenue allocated to the term license component is recognized upon delivery at the start of the subscription term while revenue for the SELECT maintenance and support is recognized as delivered over the subscription term. For Virtuoso keys, revenue is recognized as services are delivered. Billings in advance are recorded as Deferred revenues in the consolidated balance sheets. For usage‑based QTL and MTL subscriptions, revenues are recognized based upon usage incurred by the account. Usage is defined as peak usage over the respective terms. The terms of QTL and MTL subscriptions align with calendar quarters and calendar months, respectively, and revenue is recognized based on actual usage.

Visas are quarterly or annual term licenses enabling users to access specific project or enterprise information and entitles users to certain functionality of the Company’s ProjectWise and AssetWise systems. The Company’s standard offerings are usage based with monetization through the Company’s CSS program as described below.

CSS is a program designed to streamline the procurement, administration, and payment process. The program requires an estimation of annual usage for CSS eligible offerings and a deposit of funds in advance. Actual consumption is monitored and invoiced against the deposit on a calendar quarter basis. CSS balances not utilized for eligible products or services may roll over to future periods or are refundable. Paid and unconsumed CSS balances are recorded in Accruals and other current liabilities in the consolidated balance sheets. Software and services consumed under CSS are recognized pursuant to the applicable revenue recognition guidance for the respective software or service and classified as subscriptions or services based on their respective nature.

Perpetual Licenses

Perpetual licenses may be sold with or without attaching a SELECT subscription. Historically, attachment and retention of the SELECT subscription has been high given the benefits of the SELECT subscription discussed above. Perpetual licenses revenues are recognized upon delivery of the license to the user.

Services

The Company provides professional services, including training, implementation, configuration, customization, and strategic consulting services. The Company performs projects on both a time and materials and a fixed fee basis. Certain of the Company’s fixed‑fee arrangements, including its Success Services offerings, are structured as subscription‑like, packaged offerings that are annually recurring in nature. Success Services are standard service offerings that provide a level of dedicated professional services above the standard technical support offered to all accounts as part of their SELECT or enterprise agreement. Revenues are recognized as services are performed.

The Company primarily utilizes its direct internal sales force and also has arrangements through independent channel partners to promote and sell its products and subscriptions to end‑users. Channel partners are authorized to promote the sale of an authorized set of the Company’s products and subscriptions within an authorized geography under a Channel Partner Agreement.

Significant Judgments and Estimates

The Company’s contracts with customers may include promises to transfer licenses (perpetual or term‑based), maintenance, and services to a user. Judgment is required to determine if the promises are separate performance obligations, and if so, the allocation of the transaction price to each performance obligation. When an arrangement includes multiple performance obligations which are concurrently delivered and have the same pattern of transfer to the customer, the Company accounts for those performance obligations as a single performance obligation. For contracts with more than one performance obligation, the transaction price is allocated among the performance obligations in an amount that depicts the relative SSP of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately and needs to determine whether there is a discount that should be allocated based on the relative SSP of the various products and services.

The Company’s SELECT agreement provides users with perpetual licenses a right to exchange software for other eligible perpetual licenses on an annual basis upon renewal. The Company refers to this option as portfolio balancing and has concluded that the portfolio balancing feature represents a material right resulting in the deferral of the associated revenue. Judgment is required to estimate the percentage of users who may elect to portfolio balance and considers inputs such as historical user elections. This feature is available once per term and must be exercised prior to the respective renewal term. The Company recognizes the associated revenue upon election or when the portfolio balancing right expires. This right is included in the initial and subsequent renewal terms and the Company reestablishes the revenue deferral for the material right upon the beginning of the renewal term.

Software Development Costs

Software Development Costs — The Company’s software development costs, including costs to develop software products or the software component of products to be sold, leased, or marketed to external accounts, before technological feasibility is reached, are included in Research and development in the consolidated statements of operations. Research and development expenses, which are generally expensed as incurred, primarily consist of headcount‑related costs. In general, technological feasibility is reached shortly before the release of such products.

Under its Accelerated Commercial Development Program (“ACDP”) (the Company’s structured approach to an in‑house business incubator function), the Company capitalizes certain development costs related to certain projects once technological feasibility is established. Technological feasibility is established when a detailed program design has been completed and documented, the Company has established that the necessary skills, hardware, and software technology are available to produce the product, and there are no unresolved high‑risk development issues. Once the software is ready for its intended use, amortization is recorded over the software’s estimated useful life (generally three years).The Company evaluates the recoverability of capitalized ACDP costs whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable.

Advertising Expense

Advertising Expense — The Company expenses advertising costs as incurred.

Cash and Cash Equivalents

Cash and Cash Equivalents — The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. As of December 31, 2023 and 2022, all of the Company’s cash and cash equivalents consisted of money market funds and cash held in checking accounts maintained at various financial institutions. Cash equivalents are recorded at cost, which approximates fair value.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable primarily represent receivables from customers for products and services invoiced by the Company for which payment is outstanding and also unbilled revenues (see Note 3). Receivables are recorded at the invoiced amount and do not bear interest.

The Company establishes an allowance for doubtful accounts for expected losses during the accounts receivable collection process. The allowance for doubtful accounts is presented separately in the consolidated balance sheets and reduces the accounts receivable balance to the net realizable value of the outstanding accounts receivable. The development of the allowance for doubtful accounts is based on an expected loss model which considers historical write‑off and recovery experience, aging trends affecting specific accounts, and general operational factors affecting all accounts. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

The Company considers current economic trends and takes into account reasonable and supportable forecasts of future conditions when evaluating the adequacy of the allowance for doubtful accounts. If circumstances relating to specific customers change or unexpected changes occur in the general business environment, the Company’s estimate of the recoverability of receivables could be further adjusted.

Concentration of Credit Risk

Concentration of Credit Risk — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of its cash and cash equivalents, and receivables. To reduce credit risk, the Company performs ongoing credit evaluations of its customers and limits the amount of credit extended when deemed necessary. Generally, the Company requires no collateral from its customers. The Company maintains an allowance for potential credit losses, but historically has not experienced any significant losses related to individual customers or groups of customers in any particular industry or geographic region.

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023‑09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023‑09”), which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. ASU 2023‑09 is effective for the Company for the annual reporting period beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2023‑09 on its consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU No. 2023‑07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023‑07”), which expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how the Company’s CODM uses reported segment profit or loss information in assessing segment performance and allocating resources. ASU 2023‑07 is effective for the Company for the annual reporting period beginning after December 15, 2023, and interim periods beginning after December 15, 2024.

Recently Adopted Accounting Guidance

In March 2020, the FASB issued ASU No. 2020‑04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020‑04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020‑04 applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform between March 12, 2020 and December 31, 2022. In December 2022, the FASB issued ASU No. 2022‑06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting by extending the sunset date of Topic 848 to December 31, 2024. The expedients and exceptions provided by these ASUs do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2024, except for hedging relationships existing as of December 31, 2024, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The Company adopted these ASUs during the second quarter of 2023 (see Note 10) and the adoption did not have a material impact on the Company’s consolidated financial statements.

Fair Value Measurements

The Company categorizes its assets and liabilities measured at fair value into a three‑level hierarchy, based on the priority of the inputs to the respective valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). An asset or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The fair value hierarchy consists of the following three levels:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 inputs are unobservable inputs based on management’s own assumptions used to measure assets and liabilities at fair value.

The Company’s financial instruments include cash equivalents, account receivables, certain other assets, accounts payable, accruals, certain other current and long‑term liabilities, and long‑term debt.

Current Assets and Current Liabilities — In general, the carrying amounts reported on the Company’s consolidated balance sheets for current assets and current liabilities approximate their fair values due to the short‑term nature of those instruments.

The following methods and assumptions were used by the Company in estimating its fair value measurements for Level 2 and Level 3 financial instruments as of December 31, 2023 and 2022:

Acquisition Contingent Consideration — The fair value of these liabilities is generally determined using a cost or income approach and is measured based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions the Company believes would be made by a market participant.

Interest Rate Swap — The fair value of the Company’s interest rate swap asset or liability is determined using an income approach and is measured based on the implied forward rates for the remaining term of the interest rate swap. The Company considers these valuation inputs to be Level 2 inputs in the fair value hierarchy.

Long-Term Debt — The fair value of the Company’s borrowings under its Credit Facility approximated its carrying value based upon discounted cash flows at current market rates for instruments with similar remaining terms.The estimated fair value of the 2026 Notes and 2027 Notes is based on quoted market prices of the Company’s instrument in markets that are not active and are classified as Level 2 within the fair value hierarchy. Considerable judgment is necessary to interpret the market data and develop estimates of fair values. Accordingly, the estimates presented are not necessarily indicative of the amounts at which these instruments could be purchased, sold, or settled.

Deferred Compensation Plan Liabilities — The fair value of deferred compensation plan liabilities, including the liability classified phantom investments in the DCP, are marked to market at the end of each reporting period.
