Description Of Business And Summary Of Significant Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business VeriSign, Inc. (“Verisign” or “the Company”) was incorporated in Delaware on April 12, 1995. The Company has one reportable segment. The Company helps enable the security, stability, and resiliency of the Domain Name System (“DNS”) and the internet by providing Root Zone Maintainer services, operating two of the thirteen global internet root servers, and providing registration services and authoritative resolution for the . com and . net top-level domains, which support the majority of global e-commerce. Basis of Presentation The accompanying consolidated financial statements of Verisign and its subsidiaries have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States (“U.S.”). All significant intercompany accounts and transactions have been eliminated. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Reclassifications Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on net income as previously reported. Significant Accounting Policies Cash and Cash Equivalents Verisign considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents include certain money market funds, debt securities and various deposit accounts. Verisign maintains its cash and cash equivalents with financial institutions that have investment grade ratings and, as part of its cash management process, performs periodic evaluations of the relative credit standing of these financial institutions. Marketable Securities Marketable securities primarily consist of debt securities issued by the U.S. Treasury. All marketable securities are classified as available-for-sale and are carried at fair value. Unrealized gains and losses, net of taxes, are reported as a component of Accumulated other comprehensive loss. The specific identification method is used to determine the cost basis of the marketable securities sold. The Company classifies its marketable securities as current based on their nature and availability for use in current operations. The Company amortizes the discount on debt securities purchased below par value over the term of the instrument, and recognizes the amounts as interest income included in Non-operating income (loss), net. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets of 35 to 47 years for buildings, 10 years for building improvements and three years to five years for computer equipment, software, office equipment, and furniture and fixtures. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful lives of the assets or associated lease terms. Capitalized Software Software included in property and equipment includes amounts paid for purchased software and development costs for internally developed software. The Company capitalized $7.2 million and $10.6 million of costs related to internally developed software during 2023 and 2022, respectively. Goodwill and Other Long-lived Assets Goodwill represents the excess of purchase consideration over fair value of net assets of businesses acquired. The Company has only one reporting unit, which has a negative carrying value. Therefore, the goodwill is not subject to impairment. Long-lived assets, such as property, plant, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Such events or circumstances include, but are not limited to, a significant decrease in the fair value of the underlying business. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized in the amount by which the carrying amount of the asset exceeds its fair value. As of December 31, 2023, the Company’s assets include a deposit related to the purchase of the contractual rights to the . web gTLD. The amount paid to date has been recorded as a deposit until such time that the contractual rights are transferred to the Company. This asset would be tested for recoverability if the Company were to determine that it is no longer probable that the rights will be transferred. At the time of the transfer of the contractual rights, the Company will record the amount as an indefinite-lived intangible asset subject to review for impairment on an annual basis or more frequently if events or changes in circumstances indicate that an impairment is more likely than not. Foreign Currency Remeasurement Verisign conducts business in several different countries and transacts in multiple currencies. The functional currency for all of Verisign’s international subsidiaries is the U.S. dollar. The Company’s subsidiaries’ financial statements are remeasured into U.S. dollars using a combination of current and historical exchange rates and any remeasurement gains and losses are included in Non-operating income (loss), net. The Company recognized net remeasurement gains of $14.7 million in 2023. Net remeasurement gains and losses were not significant in 2022 and 2021. Verisign maintains a foreign currency risk management program designed to mitigate foreign exchange risks associated with the monetary assets and liabilities that are denominated in currencies other than the U.S. dollar. The primary objective of this program is to minimize the gains and losses resulting from fluctuations in exchange rates. The Company does not enter into foreign currency transactions for trading or speculative purposes, nor does it hedge foreign currency exposures in a manner that entirely offsets the effects of changes in exchange rates. The program may entail the use of forward or option contracts, which are derivatives and are recorded at fair market value. The Company records gains and losses on foreign currency forward contracts in Non-operating income (loss), net. The Company recognized a $ 9.8 million As of December 31, 2023, Verisign held foreign currency forward contracts in notional amounts totaling $215.7 million to mitigate the impact of exchange rate fluctuations associated with certain assets and liabilities held in foreign currencies. Revenue Recognition Revenues are recognized when control of the promised services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenues primarily arise from fixed fees charged to registrars for the initial registration or renewal of .com , .net , and other domain names. Individual customers, called registrants, contract directly with registrars or their resellers, and the registrars, who are our direct customers, in turn register the domain names with Verisign. Fees for domain name registrations and renewals are generally due at the time of registration or renewal. Domain name registration terms range from one year up to ten years. Most customers either maintain a deposit with Verisign or provide an irrevocable letter of credit in excess of the amounts owed. Verisign also offers promotional incentive-based discount programs to its registrars based upon market conditions and the business environment in which the registrars operate. Amounts payable for these programs are recorded as a reduction of revenue. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Each domain name registration or renewal is considered a separate optional purchase and represents a single performance obligation, which is to allow its registration and maintain that registration (by allowing updates, DNS resolution and Whois services, which allow users to find information about registered domain names) through the registration term. These services are provided continuously throughout each registration term, and as such, revenues from the initial registration or renewal of domain names are deferred and recognized ratably over the registration term. Fees for renewals and advance extensions to the existing term are deferred until the new incremental period commences. These fees are then recognized ratably over the renewal or extension term. Costs Incurred to Obtain a Contract The Company recognizes the fees payable to ICANN for each annual term of domain name registrations and renewals, as an asset which is amortized on a straight-line basis over the related registration term. These assets are included in Other current assets and Other long-term assets. Income Taxes Verisign uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company records a valuation allowance to reduce deferred tax assets to an amount whose realization is more likely than not. For every tax-paying component and within each tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single net noncurrent asset or liability. The Company recognizes the U.S. income tax effect of future global intangible low-taxed income inclusions in the period in which they arise. The Company’s income taxes payable is reduced by the tax benefits from restricted stock unit (“RSU”) vestings equal to the fair market value of the stock at the vesting date. If the income tax benefit at the vesting date differs from the income tax benefit recorded based on the grant date fair value of the RSUs, the excess or shortfall of the tax benefit is recognized within income tax expense. Verisign operates in multiple tax jurisdictions in the United States and internationally. Tax laws and regulations in these jurisdictions are complex, interrelated, and periodically changing. Significant judgment or interpretation of these laws and regulations is often required in determining the Company’s worldwide provision for income taxes, including, for example, the calculations of taxable income in each jurisdiction, deferred taxes, and the availability and amount of deductions and tax credits. The final taxes payable are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from various tax examinations. The Company only recognizes tax positions taken or expected to be taken on its tax returns that are more likely than not to be sustained upon examination, and records a tax benefit amount that is more likely than not to be realized upon ultimate settlement with the taxing authority. The Company adjusts its estimate of unrecognized tax benefits in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in an outcome that is materially different from the estimate. See Note 10, “Income Taxes,” for details of the changes to the Company’s unrecognized tax benefits for the periods presented. Stock-based Compensation The Company’s stock-based compensation consists of RSUs granted to employees and the employee stock purchase plan (“ESPP”). Stock-based compensation expense is typically recognized ratably over the requisite service period. Forfeitures of stock-based awards are recognized as they occur. As substantially all of the RSUs granted by the Company are routine annual grants, none of the awards are designed to be spring-loaded, and as such, the Company does not adjust the market price of its common stock when estimating the grant-date fair value of these awards. The Company also grants RSUs which include performance conditions, and in some cases market conditions, to certain executives. The expense for these performance-based RSUs is recognized based on the probable outcome of the performance conditions. The expense recognized for awards with market conditions is based on the grant date fair value of the awards including the impact of the market conditions, using a Monte Carlo simulation model. The Company uses the Black-Scholes option pricing model to determine the fair value of its ESPP offerings. The determination of the fair value of stock-based payment awards using the Monte Carlo simulation model or the Black-Scholes option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. Earnings per Share The Company computes basic earnings per share by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share gives effect to dilutive potential common shares, including unvested RSUs and ESPP offerings, using the treasury stock method. Fair Value of Financial Instruments The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: • Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3: Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. Legal Proceedings Verisign is involved in various investigations, claims and lawsuits arising in the normal conduct of its business, none of which, in its opinion, will have a material adverse effect on its financial condition, results of operations, or cash flows. The Company can provide no assurance that it will prevail in any litigation. Regardless of the outcome, any litigation may require the Company to incur significant litigation expense and may result in significant diversion of management attention. While certain legal proceedings and related indemnification obligations to which the Company is a party specify the amounts claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of the litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated, except in circumstances where an aggregate litigation accrual has been recorded for probable and reasonably estimable loss contingencies. A determination of the amount of accrual required, if any, for these contingencies is made after careful analysis of each matter. The required accrual may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. The Company does not believe that any such matter currently being reviewed will have a material adverse effect on its financial condition, results of operations, or cash flows. Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which requires additional disclosure of significant segment expenses on an annual and interim basis. This guidance will be applied retrospectively and will be effective for the annual periods beginning the year ended December 31, 2024, and for interim periods beginning January 1, 2025. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction.This guidance will be effective for the annual periods beginning the year ended December 31, 2025. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

Revenues for each region may be impacted by registrars reincorporating, relocating, or from acquisitions or changes in affiliations of resellers. Revenues for each region may also be impacted by registrars domiciled in one region, registering domain names in another region. Major Customers Our largest customer accounted for approximately 32% of revenues in 2023 and 2022 and approximately 33% of revenues in 2021. The Company does not believe that the loss of this customer would have a material adverse effect on the Company’s business because, in that event, end-users of this customer would transfer to the Company’s other existing customers.

Employee Benefits And Stock-Based Compensation	Employee Benefits and Stock-based Compensation 401(k) Plan The Company maintains a defined contribution 401(k) plan (the “401(k) Plan”) for substantially all of its U.S. employees. Under the 401(k) Plan, eligible employees may contribute up to 50% of their pre-tax salary, subject to the Internal Revenue Service (“IRS”) annual contribution limits. The Company matches 50% of up to the first 8% of the employee’s annual salary contributed to the plan. The Company contributed $5.8 million in 2023, $5.5 million in 2022, and $5.2 million in 2021 under the 401(k) Plan. The Company can terminate matching contributions at its discretion at any time. Equity Incentive Plan The majority of Verisign’s stock-based compensation relates to RSUs granted under the 2006 Equity Incentive Plan (the “2006 Plan”). As of December 31, 2023, a total of 7.5 million shares of common stock remain reserved for issuance upon the vesting of RSUs and for the future grant of equity awards. The 2006 Plan authorizes the award of incentive stock options to employees and non-qualified stock options, restricted stock awards, RSUs, stock bonus awards, stock appreciation rights and performance shares to eligible employees, officers, directors, consultants, independent contractors and advisers. The 2006 Plan is administered by the Compensation Committee which may delegate to a committee of one or more members of the Board or Verisign’s officers the ability to grant certain awards and take certain other actions with respect to participants who are not executive officers or non-employee directors. RSUs are awards covering a specified number of shares of Verisign common stock that may be settled by issuance of those shares (which may be restricted shares). RSUs generally vest over four years. Certain RSUs with performance and market conditions (“PSUs”), granted to the Company’s executives, generally vest over a three year term. Additionally, the Company has granted fully vested RSUs to members of its Board in each of the last three years. The Compensation Committee may authorize grants with a different vesting schedule in the future. 2007 Employee Stock Purchase Plan Eligible employees of the Company may purchase common stock under the 2007 Employee Stock Purchase Plan through payroll deductions by electing to have between 2% and 25% of their compensation withheld to cover the purchase price. Each participant is granted an option to purchase common stock. This option is automatically exercised on the last day of each six-month purchase period during the offering period. The purchase price for the common stock under the ESPP is 85% of the lesser of the fair market value of the common stock on the first day of the applicable offering period or the last day of the applicable purchase period. Offering periods begin on the first business day of February and August of each year. As of December 31, 2023, 2.8 million shares of the Company’s common stock remain reserved for future issuance under this plan. Stock-based Compensation Stock-based compensation is classified in the Consolidated Statements of Comprehensive Income in the same expense line items as cash compensation.

Income Tax Disclosure [Text Block]	Income Taxes Income before income taxes is categorized geographically as follows: Year Ended December 31, 2023 2022 2021 (In millions) United States $ 607.1 $ 558.5 $ 489.4 Foreign 369.4 321.7 292.8 Total income before income taxes $ 976.5 $ 880.2 $ 782.2 The provision for income taxes consisted of the following: Year Ended December 31, 2023 2022 2021 (In millions) Current expense: Federal $ 159.1 $ 145.1 $ 97.5 State 28.0 41.7 32.2 Foreign, including withholding tax 24.4 26.3 29.8 211.5 213.1 159.5 Deferred expense (benefit): Federal (25.6) (18.0) 3.9 State 11.2 (4.8) (0.2) Foreign (38.2) 16.1 (165.8) (52.6) (6.7) (162.1) Total income tax expense (benefit) $ 158.9 $ 206.4 $ (2.6) The Company's state current expense was lower in 2023 due to a beneficial change in certain state income apportionment rules, which became effective starting in 2023. The new apportionment rules required the Company to write down certain of its deferred tax assets resulting in a net state deferred expense in 2023. The difference between income tax expense (benefit) and the amount resulting from applying the federal statutory rate of 21% to Income before income taxes is attributable to the following: Year Ended December 31, 2023 2022 2021 (In millions) Income tax expense at federal statutory rate $ 205.1 $ 184.8 $ 164.3 Non-U.S. intellectual property (118.0) — (165.5) Change in valuation allowance 66.1 0.1 0.1 State taxes, net of federal benefit 28.5 29.2 25.5 Effect of non-U.S. operations (15.5) (9.5) (23.3) Remeasurement of unrecognized tax benefits (8.3) (1.5) (5.1) Other 1.0 3.3 1.4 Total income tax expense (benefit) $ 158.9 $ 206.4 $ (2.6) During the fourth quarter of 2023, due to a change in local tax systems, the Company recognized amortizable tax basis related to a portion of its non-U.S. intellectual property based on a fair value of approximately $1.80 billion. This intellectual property had no book value, resulting in the recognition of a $118.0 million deferred tax asset and a corresponding income tax benefit in 2023. During the fourth quarter of 2021, as part of a legal entity reorganization, the Company completed an internal transfer of certain of its non-U.S. intellectual property which had no book value. This transfer created amortizable tax basis for the receiving entity based on the $1.20 billion fair value of the intellectual property, which resulted in the recognition of a $165.5 million deferred tax asset and a corresponding income tax benefit. During the fourth quarter of 2023, due to the change in the tax systems mentioned above, the Company determined that it is more likely than not that a portion of the aforementioned deferred tax asset will not be realized, and as a result, recognized a valuation allowance of $64.7 million. The tax effects of temporary differences that give rise to significant portions of the Company’s deferred tax assets and liabilities are as follows: As of December 31, 2023 2022 (In millions) Deferred tax assets: Intellectual property $ 266.2 $ 147.0 Deferred revenue, accruals and reserves 72.9 73.7 Research and development costs 23.6 12.0 Tax credit carryforwards 4.6 3.8 Net operating loss carryforwards 2.2 3.4 Other 6.0 1.8 Total deferred tax assets 375.5 241.7 Valuation allowance (73.6) (5.5) Net deferred tax assets 301.9 236.2 Deferred tax liabilities (0.9) (1.6) Total net deferred tax assets $ 301.0 $ 234.6 With the exception of a portion of deferred tax assets related to intellectual property and certain state and foreign net operating loss and foreign tax credit carryforwards, management believes it is more likely than not that the tax effects of the deferred tax liabilities together with future taxable income, will be sufficient to fully recover the remaining deferred tax assets. As part of the Tax Cuts and Jobs Act of 2017, domestic and foreign research and development expenses, including costs related to internally developed software, are required to be amortized for income tax purposes, over five and fifteen years, respectively, beginning with our 2022 tax year. As of December 31, 2023, the Company’s deferred tax assets included $38.4 million of state net operating loss carryforwards, before applying tax rates for the respective jurisdictions. The tax credit carryforwards as of December 31, 2023 consisted primarily of foreign tax credit carryforwards. The state net operating loss carryforwards expire in various years from 2024 through 2034. The foreign tax credits will expire between 2028 and 2033. A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows: As of December 31, 2023 2022 (In millions) Beginning balance $ 15.1 $ 16.0 Increases in tax positions for prior years 0.1 0.1 Increases in tax positions for current year 5.0 1.4 Lapse in statute of limitations (10.6) (2.4) Ending balance $ 9.6 $ 15.1 As of December 31, 2023, approximately $7.1 million of unrecognized tax benefits, including penalties and interest, could affect the Company’s tax provision and effective tax rate. The Company does not expect the balance of unrecognized tax benefits to change materially during the next twelve months. In accordance with its accounting policy, the Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. These accruals were not material in any period presented. The Company’s major taxing jurisdictions are the U.S., the Commonwealth of Virginia, and Switzerland. The Company’s U.S. federal income tax returns are not currently under examination by the IRS and only the Company’s tax returns for 2020 and years thereafter are subject to examination. The Company’s other material tax returns are not currently under examination by their respective taxing jurisdictions. Because the Company has previously used net operating loss carryforwards and other tax attributes to offset its taxable income in income tax returns for the U.S. and Virginia, such attributes can be adjusted by these taxing authorities until the statute of limitations closes on the year in which such attributes were utilized. The open years for examination in Switzerland are the 2019 tax year and forward.

The Company’s significant purchase obligations include firm commitments with telecommunication carriers, other service providers and the fixed portion of registry fees related to the operation of certain top-level domains. Registry fees for top-level domains that we operate where the amounts are variable or passed-through to registrars have been excluded from the table above. The Company has an agreement with Internet Corporation for Assigned Names and Numbers (“ICANN”) to be the sole registry operator for domain names in the .com registry through November 30, 2024. Under this agreement, the Company pays ICANN on a quarterly basis, $0.25 for each annual term of a domain name registered or renewed during such quarter. The Company incurred registry fees for the . com registry of $38.1 million in 2023, $39.9 million in 2022, and $40.6 million in 2021. In connection with the . com Registry Agreement with ICANN, the Company is required to make annual payments of $4.0 million to ICANN through 2025 to support efforts to maintain the security and stability of the DNS. The payments for 2024 and 2025 are included in Purchase obligations in the table above.

Cash And Cash Equivalents	Cash and Cash Equivalents
Marketable Securities	Marketable Securities Marketable securities primarily consist of debt securities issued by the U.S. Treasury. All marketable securities are classified as available-for-sale and are carried at fair value. Unrealized gains and losses, net of taxes, are reported as a component of Accumulated other comprehensive loss. The specific identification method is used to determine the cost basis of the marketable securities sold. The Company classifies its marketable securities as current based on their nature and availability for use in current operations. The Company amortizes the discount on debt securities purchased below par value over the term of the instrument, and recognizes the amounts as interest income included in Non-operating income (loss), net.
Property And Equipment	Property and Equipment
Capitalized Software	Capitalized Software Software included in property and equipment includes amounts paid for purchased software and development costs for internally developed software. The Company capitalized $7.2 million and $10.6 million of costs related to internally developed software during 2023 and 2022, respectively.
Goodwill And Other Long-Lived Assets	Goodwill and Other Long-lived Assets Goodwill represents the excess of purchase consideration over fair value of net assets of businesses acquired. The Company has only one reporting unit, which has a negative carrying value. Therefore, the goodwill is not subject to impairment. Long-lived assets, such as property, plant, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Such events or circumstances include, but are not limited to, a significant decrease in the fair value of the underlying business. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group, to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. An impairment charge is recognized in the amount by which the carrying amount of the asset exceeds its fair value. As of December 31, 2023, the Company’s assets include a deposit related to the purchase of the contractual rights to the . web
Foreign Currency Remeasurement	Foreign Currency Remeasurement Verisign conducts business in several different countries and transacts in multiple currencies. The functional currency for all of Verisign’s international subsidiaries is the U.S. dollar. The Company’s subsidiaries’ financial statements are remeasured into U.S. dollars using a combination of current and historical exchange rates and any remeasurement gains and losses are included in Non-operating income (loss), net. The Company recognized net remeasurement gains of $14.7 million in 2023. Net remeasurement gains and losses were not significant in 2022 and 2021. Verisign maintains a foreign currency risk management program designed to mitigate foreign exchange risks associated with the monetary assets and liabilities that are denominated in currencies other than the U.S. dollar. The primary objective of this program is to minimize the gains and losses resulting from fluctuations in exchange rates. The Company does not enter into foreign currency transactions for trading or speculative purposes, nor does it hedge foreign currency exposures in a manner that entirely offsets the effects of changes in exchange rates. The program may entail the use of forward or option contracts, which are derivatives and are recorded at fair market value. The Company records gains and losses on foreign currency forward contracts in Non-operating income (loss), net. The Company recognized a $ 9.8 million
Revenue Recognition	Revenue Recognition Revenues are recognized when control of the promised services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenues primarily arise from fixed fees charged to registrars for the initial registration or renewal of .com , .net , and other domain names. Individual customers, called registrants, contract directly with registrars or their resellers, and the registrars, who are our direct customers, in turn register the domain names with Verisign. Fees for domain name registrations and renewals are generally due at the time of registration or renewal. Domain name registration terms range from one year up to ten years. Most customers either maintain a deposit with Verisign or provide an irrevocable letter of credit in excess of the amounts owed. Verisign also offers promotional incentive-based discount programs to its registrars based upon market conditions and the business environment in which the registrars operate. Amounts payable for these programs are recorded as a reduction of revenue. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Each domain name registration or renewal is considered a separate optional purchase and represents a single performance obligation, which is to allow its registration and maintain that registration (by allowing updates, DNS resolution and Whois services, which allow users to find information about registered domain names) through the registration term. These services are provided continuously throughout each registration term, and as such, revenues from the initial registration or renewal of domain names are deferred and recognized ratably over the registration term. Fees for renewals and advance extensions to the existing term are deferred until the new incremental period commences. These fees are then recognized ratably over the renewal or extension term. Costs Incurred to Obtain a Contract The Company recognizes the fees payable to ICANN for each annual term of domain name registrations and renewals, as an asset which is amortized on a straight-line basis over the related registration term. These assets are included in Other current assets and Other long-term assets.
Income Taxes	Income Taxes Verisign uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company records a valuation allowance to reduce deferred tax assets to an amount whose realization is more likely than not. For every tax-paying component and within each tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single net noncurrent asset or liability. The Company recognizes the U.S. income tax effect of future global intangible low-taxed income inclusions in the period in which they arise. The Company’s income taxes payable is reduced by the tax benefits from restricted stock unit (“RSU”) vestings equal to the fair market value of the stock at the vesting date. If the income tax benefit at the vesting date differs from the income tax benefit recorded based on the grant date fair value of the RSUs, the excess or shortfall of the tax benefit is recognized within income tax expense. Verisign operates in multiple tax jurisdictions in the United States and internationally. Tax laws and regulations in these jurisdictions are complex, interrelated, and periodically changing. Significant judgment or interpretation of these laws and regulations is often required in determining the Company’s worldwide provision for income taxes, including, for example, the calculations of taxable income in each jurisdiction, deferred taxes, and the availability and amount of deductions and tax credits. The final taxes payable are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from various tax examinations. The Company only recognizes tax positions taken or expected to be taken on its tax returns that are more likely than not to be sustained upon examination, and records a tax benefit amount that is more likely than not to be realized upon ultimate settlement with the taxing authority. The Company adjusts its estimate of unrecognized tax benefits in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in an outcome that is materially different from the estimate. See Note 10, “Income Taxes,” for details of the changes to the Company’s unrecognized tax benefits for the periods presented.
Stock-Based Compensation	Stock-based Compensation The Company’s stock-based compensation consists of RSUs granted to employees and the employee stock purchase plan (“ESPP”). Stock-based compensation expense is typically recognized ratably over the requisite service period. Forfeitures of stock-based awards are recognized as they occur. As substantially all of the RSUs granted by the Company are routine annual grants, none of the awards are designed to be spring-loaded, and as such, the Company does not adjust the market price of its common stock when estimating the grant-date fair value of these awards. The Company also grants RSUs which include performance conditions, and in some cases market conditions, to certain executives. The expense for these performance-based RSUs is recognized based on the probable outcome of the performance conditions. The expense recognized for awards with market conditions is based on the grant date fair value of the awards including the impact of the market conditions, using a Monte Carlo simulation model. The Company uses the Black-Scholes option pricing model to determine the fair value of its ESPP offerings. The determination of the fair value of stock-based payment awards using the Monte Carlo simulation model or the Black-Scholes option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables.
Earnings Per Share	Earnings per Share The Company computes basic earnings per share by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share gives effect to dilutive potential common shares, including unvested RSUs and ESPP offerings, using the treasury stock method.
Fair Value Of Financial Instruments	Fair Value of Financial Instruments The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: • Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. •
Legal Proceedings	Legal Proceedings Verisign is involved in various investigations, claims and lawsuits arising in the normal conduct of its business, none of which, in its opinion, will have a material adverse effect on its financial condition, results of operations, or cash flows. The Company can provide no assurance that it will prevail in any litigation. Regardless of the outcome, any litigation may require the Company to incur significant litigation expense and may result in significant diversion of management attention. While certain legal proceedings and related indemnification obligations to which the Company is a party specify the amounts claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of the litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated, except in circumstances where an aggregate litigation accrual has been recorded for probable and reasonably estimable loss contingencies. A determination of the amount of accrual required, if any, for these contingencies is made after careful analysis of each matter. The required accrual may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. The Company does not believe that any such matter currently being reviewed will have a material adverse effect on its financial condition, results of operations, or cash flows.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which requires additional disclosure of significant segment expenses on an annual and interim basis. This guidance will be applied retrospectively and will be effective for the annual periods beginning the year ended December 31, 2024, and for interim periods beginning January 1, 2025. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction.This guidance will be effective for the annual periods beginning the year ended December 31, 2025. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
