Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Consolidation Policy The consolidated financial statements of the Company include the accounts of its wholly-owned subsidiaries in the Americas; Europe, the Middle East and Africa (“EMEA”); and Asia-Pacific and Japan (“APJ”). All significant transactions and balances between the Company and its subsidiaries have been eliminated in consolidation. Recent Accounting Pronouncements Business Combinations In October 2021, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update on business combinations. The new guidance requires companies to apply revenue guidance under Accounting Standards Codification Topic 606 to recognize and measure contract assets and contract liabilities acquired in a business combination on the acquisition date. This approach differs from the current requirement to measure contract assets and contract liabilities acquired in a business combination at fair value. The update will be effective for the Company beginning in the first quarter of 2023, though early adoption is permitted. The Company is currently evaluating the timing of adoption and impact of this new standard. Income Taxes In December 2019, the FASB issued an accounting standard update on income taxes. The new guidance eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The Company adopted this standard effective January 1, 2021. The adoption of this standard did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the FASB issued an accounting standard update to guidance applicable to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for all entities as of March 12, 2020, through December 31, 2022. The Company is currently evaluating the impact, but does not expect the standard to have a material impact on its consolidated financial position, results of operations and cash flows. Reclassifications Certain reclassifications of the prior years' amounts have been made to conform to the current year's presentation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates made by management include estimation for reserves for legal contingencies, the standalone selling price of certain performance obligations related to revenue recognition, the provision for credit losses related to accounts receivable, contract assets, and available-for-sale debt securities, the provision to reduce obsolete or excess inventory to net realizable value, the provision for estimated returns, as well as sales allowances, the assumptions used in the valuation of stock-based awards and measurement of expense related to performance stock units, the assumptions used in the discounted cash flows to mark certain of its investments to market, the valuation of the Company’s goodwill, valuation of acquired intangible assets and liabilities, net realizable value of product related and other intangible assets, the provision for income taxes, valuation allowance for deferred tax assets, uncertain tax positions, and the amortization and depreciation periods for contract acquisition costs, intangible and long-lived assets. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole, the actual amounts of such items, when known, will vary from these estimates. Cash and Cash Equivalents Cash and cash equivalents at December 31, 2021 and 2020 include marketable securities, which are primarily money market funds, corporate securities and government securities with initial or remaining contractual maturities when purchased of three months or less. Available-for-sale Investments Short-term and long-term available for sale investments in debt securities at December 31, 2021 and 2020 primarily consist of agency securities, corporate securities and government securities. Investments classified as available-for-sale debt securities are stated at fair value with unrealized gains and losses, net of taxes, reported in Accumulated other comprehensive loss in the accompanying consolidated balance sheets. The Company classifies its available-for-sale investments as current and non-current based on their actual remaining time to maturity. The Company does not recognize unrealized changes in the fair value of its available-for-sale debt securities in income unless a security is deemed to be impaired. The allowance for credit losses on the Company's investments in available-for-sale debt securities is determined using a quantitative discounted cash flow analysis if impairment triggers exist after a qualitative screen is completed. Impairment on available-for-sale debt securities is determined on an individual security basis and the security is subject to impairment when its fair value declines below its amortized cost basis. If the fair value is less than the amortized cost basis, management must then determine whether it intends to sell the security or whether it is more likely than not that it will be required to sell the security before it recovers its value. If management intends to sell the security or will more-likely-than-not be required to sell the impaired security before it recovers its value, a credit loss is recorded to Other income, net in the accompanying consolidated statements of inc ome. If management does not intend to sell the security, nor will it more-likely-than-not be required to sell the security before the security recovers its value, management must then determine whether the loss is due to credit loss or other factors. For impairment indicators due to credit loss factors, management establishes an allowance for credit losses with a charge to Other income, net. F or impairment indicators due to other factors, management records the loss with a charge to Accumulated other comprehensive loss in the accompanying consolidated balance sheets. See Note 5 for additional information regarding the Company’s investments. Fair Value Measurements The authoritative guidance defines fair value as an exit price, representing the amount that would either be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: • Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2 . Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and • Level 3 . Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Available-for-sale securities included in Level 2 are valued utilizing inputs obtained from an independent pricing service (the “Service”) which uses quoted market prices for identical or comparable instruments rather than direct observations of quoted prices in active markets. The Service applies a four level hierarchical pricing methodology to all of the Company’s fixed income securities based on the circumstances. The hierarchy starts with the highest priority pricing source, then subsequently uses inputs obtained from other third-party sources and large custodial institutions. The Service’s providers utilize a variety of inputs to determine their quoted prices. These inputs may include interest rates, known historical trades, yield curve information, benchmark data, prepayment speeds, credit quality and broker/dealer quotes. Substantially all of the Company’s available-for-sale investments are valued utilizing inputs obtained from the Service and accordingly are categorized as Level 2. The Company periodically independently assesses the pricing obtained from the Service and historically has not adjusted the Service's pricing as a result of this assessment. Available-for-sale securities are included in Level 3 when relevant observable inputs for a security are not available. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of assets and liabilities within the fair value hierarchy. In certain instances, the inputs used to measure fair value may meet the definition of more than one level of the fair value hierarchy. The input with the lowest level priority is used to determine the applicable level in the fair value hierarchy. See Note 5 for additional information regarding the Company’s fair value measurements. Inventory Inventories are stated at the lower of cost or net realizable value on a standard cost basis, which approximates actual cost. The Company’s inventories primarily consist of finished goods as of December 31, 2021 and 2020. Contract acquisition costs The Company is required to capitalize certain contract acquisition costs, consisting primarily of commissions paid and related payroll taxes when contracts are signed. The asset recognized from capitalized incremental and recoverable acquisition costs is amortized over the expected period of benefit on a basis consistent with the pattern of transfer of the products or services to which the asset relates. The Company elects to apply a practical expedient to expense contract acquisition costs as incurred where the pattern of transfer is one year or less. The Company’s typical contracts include performance obligations related to subscription, product and licenses, and support and services. Contract acquisition costs are allocated to performance obligations using a portfolio approach. The Company assesses its sales compensation plans at least annually to evaluate whether contract acquisition costs for renewals and extensions are commensurate with those related to initial contracts. If concluded to be commensurate, the contract acquisition costs are amortized over the contractual term on a basis consistent with the pattern of transfer of the products or services to which the asset relates. If concluded not to be commensurate, the contract acquisition costs are amortized over the greater of the contractual term or estimated customer life on a basis consistent with the pattern of transfer of the products or services to which the asset relates. The Company estimates an average customer life of three years to five years, which it believes is appropriate based on consideration of the historical average customer life and the estimated useful life of the underlying product and license sold as part of the transaction. For the years ended on December 31, 2021, 2020 and 2019, the Company recorded amortization of capitalized contract acquisition costs of $76.6 million, $57.5 million and $44.8 million, respectively, which are included in Sales, Marketing and Services expense in the accompanying consolidated statements of income. As of December 31, 2021 and 2020, the Company's short-term and long-term contract acquisition costs were $82.4 million and $144.2 million, and $71.5 million and $124.7 million, respectively, and are included in Prepaid expenses and other current assets and Other assets, respectively, in the accompanying consolidated balance sheets. Derivatives and Hedging Activities In accordance with the authoritative guidance, the Company records derivatives at fair value as either assets or liabilities on the balance sheet. For derivatives that are designated as and qualify as cash flow hedges, the unrealized gain or loss on the derivative instrument is reported as a component of Accumulated other comprehensive loss and reclassified into earnings as operating expense, net, when the hedged transaction affects earnings. Derivatives not designated as hedging instruments are adjusted to fair value through earnings as Other income, net, in the period during which changes in fair value occur. The application of the authoritative guidance could impact the volatility of earnings. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes attributing all derivatives that are designated as cash flow hedges of forecasted transactions. The Company also formally assesses, both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in cash flows of the hedged item. Fluctuations in the value of the derivative instruments are generally offset by changes in the hedged item; however, if it is determined that a derivative is not highly effective as a hedge or if a derivative ceases to be a highly effective hedge, the Company will discontinue hedge accounting prospectively for the affected derivative. The Company is exposed to risk of default by its hedging counterparties. Although this risk is concentrated among a limited number of counterparties, the Company’s foreign exchange hedging policy attempts to minimize this risk by placing limits on the amount of exposure that may exist with any single financial institution at a time. Property and Equipment Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is generally three years for computer equipment; the lesser of the lease term or ten years for leasehold improvements, which is the estimated useful life; seven years for office equipment and furniture and the Company’s enterprise resource planning systems; and forty years for buildings. During 2021 and 2020, the Company retired $196.7 million and $9.3 million, respectively, in property and equipment that were no longer in use. At the time of retirement, the remaining net book value of the assets retired was not material and no material asset retirement obligations were associated with them. Property and equipment consisted of the following: December 31, 2021 2020 (In thousands) Buildings $ 68,663 $ 76,152 Computer equipment 194,317 209,605 Software 431,237 467,553 Equipment and furniture 65,113 88,019 Leasehold improvements 161,425 201,645 920,755 1,042,974 Less: accumulated depreciation and amortization (733,130) (861,933) Assets under construction 15,044 11,001 Land 16,362 16,769 Total $ 219,031 $ 208,811 Long-Lived Assets The Company reviews for impairment of long-lived assets and certain identifiable intangible assets to be held and used whenever events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss is based on the fair value of the asset compared to its carrying value. Long-lived assets and certain identifiable intangible assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. During the year ended December 31, 2021, as a result of restructuring activities, the Company impaired certain property and equipment and recorded charges of $8.5 million, which are included in Restructuring in the consolidated statements of income. See Note 17 for further information about the restructuring. Goodwill The Company accounts for goodwill in accordance with the authoritative guidance, which requires that goodwill and certain intangible assets are not amortized, but are subject to an annual impairment test. There was no impairment of goodwill or indefinite lived intangible assets as a result of the annual impairment analysis completed during the fourth quarters of 2021 and 2020. See Note 12 for more information regarding the Company's segment. The following table presents the change in goodwill during 2021 and 2020 (in thousands): Balance at January 1, 2021 Additions Other Balance at December 31, 2021 Balance at January 1, 2020 Additions Other Balance at December 31, 2020 Goodwill $ 1,798,408 $ 1,602,384 (1) $ — $ 3,400,792 $ 1,798,408 $ — $ — $ 1,798,408 (1) Amounts relate to the Wrike acquisition. See Note 6 for more information. Intangible Assets The Company has intangible assets which were primarily acquired in conjunction with business combinations and technology purchases. Intangible assets with finite lives are recorded at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally two seven Intangible assets consist of the following (in thousands): December 31, 2021 Gross Carrying Amount Accumulated Amortization Weighted-Average Life (Years) Product related intangible assets $ 1,049,406 $ 704,190 6.09 Other 664,791 249,714 6.57 Total $ 1,714,197 $ 953,904 6.28 December 31, 2020 Gross Carrying Amount Accumulated Amortization Weighted-Average Life (Years) Product related intangible assets $ 742,949 $ 665,798 6.06 Other 187,791 183,451 6.22 Total $ 930,740 $ 849,249 6.09 Amortization and impairment of product related intangible assets, which consists primarily of product related technologies and patents, was $91.4 million and $32.8 million for the year ended December 31, 2021 and 2020, respectively, and is classified as a component of Cost of net revenues in the accompanying consolidated statements of income. Amortization of other intangible assets, which consist primarily of customer relationships, trade names, backlog and covenants not to compete was $66.3 million and $2.8 million for the year ended December 31, 2021 and 2020, respectively, and is classified as a component of Operating expenses in the accompanying consolidated statements of income. The Company monitors its intangible assets for indicators of impairment. If the Company determines that impairment has occurred, it writes-down the intangible asset to its fair value. For certain intangible assets where the unamortized balances exceed the undiscounted future net cash flow, the Company measures the amount of the impairment by calculating the amount by which the carrying values exceed the estimated fair values, which are based on projected discounted future net cash flows. During the year ended December 31, 2021, the Company's management performed a comprehensive operational review which included an evaluation of all its products. In connection with this review, the Company determined that the Sapho Inc. technology, which was acquired by the Company on November 13, 2018, was a non-core solution and that the related product offerings will no longer be developed by the Company. As a result, the Company impaired the remaining carrying value related to this acquired developed technology and recorded impairment charges of $19.4 million, which are included in Amortization and impairment of product related intangible assets in the accompanying consolidated statements of income. During the year ended December 31, 2019, the Company tested certain intangible assets for recoverability and, as a result, identified certain definite-lived intangible assets, primarily technology developed by Cedexis Inc., which was acquired by the Company on February 6, 2018, that were impaired and recorded non-cash impairment charges of $13.2 million to write down the intangible assets to their estimated fair value of $4.1 million. The impairment charge is included in Amortization and impairment of product related intangible assets in the accompanying consolidated statements of income. This non-recurring fair value measurement was categorized as Level 3, as significant unobservable inputs were used in the valuation analysis. Key assumptions used in the valuation include forecasts of revenue and expenses over an extended period of time, customer churn rates, rate of migration to future technology, tax rates, and estimated costs of debt and equity capital to discount the projected cash flows. Certain of these assumptions involve significant judgment, are based on management’s estimate of current and forecasted market conditions and are sensitive and susceptible to change; therefore, further disruptions in the business could potentially result in additional amounts becoming impaired. Estimated future amortization expense of intangible assets with finite lives as of December 31, 2021 is as follows (in thousands): Year ending December 31, 2022 $ 147,166 2023 138,618 2024 130,755 2025 128,270 2026 126,699 Thereafter 88,785 Total $ 760,293 Software Development Costs The authoritative guidance requires certain internal software development costs related to software to be sold to be capitalized upon the establishment of technological feasibility. The Company's software development costs incurred subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred. Internal Use Software In accordance with the authoritative guidance, the Company capitalizes external direct costs of materials and services and internal costs such as payroll and benefits of those employees directly associated with the development of new functionality in internal use software. The amount of costs capitalized during the years ended December 31, 2021 and 2020 relating to internal use software was $3.7 million and $2.1 million, respectively. These costs are being amortized over the estimated useful life of the software, which is generally three years to seven years, and are included in property and equipment in the accompanying consolidated balance sheets. The total amounts charged to expense relating to internal use software was $5.8 million, $12.6 million and $19.7 million, during the years ended December 31, 2021, 2020 and 2019, respectively. The Company capitalized costs related to internally developed computer software to be sold as a service related to its Workspace offerings, incurred during the application development stage, of $31.1 million and $22.3 million, during the years ended December 31, 2021 and 2020, respectively, and is amortizing these costs once the project is completed and placed in service over the expected lives of the related services, which is generally two years to five years, and are included in property and equipment in the accompanying consolidated balance sheets. The total amounts charged to expense relating to internally developed computer software to be sold as a service was $12.6 million, $11.8 million and $13.0 million, during the years ended December 31, 2021, 2020 and 2019, respectively, which are included in Cost of subscription, support and services in the accompanying consolidated statements of income. During the year ended December 31, 2021, as a result of certain restructuring activities, the Company impaired the remaining carrying value of $6.2 million related to capitalized internal use software that has no ongoing economic benefit, which is included in Restructuring in the accompanying consolidated statements of income. See Note 17 for further information about the restructuring. Pension Liability The Company provides retirement benefits to certain employees who are not U.S. based. Generally, benefits under these programs are based on an employee’s length of service and level of compensation. The majority of these programs are commonly referred to as termination indemnities, which provide retirement benefits in accordance with programs mandated by the governments of the countries in which such employees work. The Company had accrued $10.0 million and $14.0 million for these pension liabilities at December 31, 2021 and 2020, respectively. Expenses for the programs for 2021, 2020 and 2019 amounted to $1.2 million, $1.2 million and $1.6 million, respectively. Revenue Significant Judgments The Company generates all of its revenues from contracts with customers. At contract inception, the Company assesses the solutions or services, or bundles of solutions and services, obligated in the contract with a customer to identify each performance obligation within the contract, and then evaluates whether the performance obligations are capable of being distinct and distinct within the context of the contract. Solutions and services that are not both capable of being distinct and distinct within the context of the contract are combined and treated as a single performance obligation in determining the allocation and recognition of revenue. The standalone selling price is the price at which the Company would sell a promised product or service separately to the customer. For the majority of the Company's software licenses and hardware, CSP and on-premise subscription software licenses, the Company uses the observable price in transactions with multiple performance obligations. For the majority of the Company’s support and services, and cloud-hosted subscription offerings, the Company uses the observable price when the Company sells that support and service and cloud-hosted subscription separately to similar customers. If the standalone selling price for a performance obligation is not directly observable, the Company estimates it. The Company estimates the standalone selling price by taking into consideration market conditions, economics of the offering and customers’ behavior. The Company maximizes the use of observable inputs and applies estimation methods consistently in similar circumstances. The Company allocates the transaction price to each distinct performance obligation on a relative standalone selling price basis. Product Concentration The Company derives a substantial portion of its revenues from its Workspace solutions, which include its Citrix Virtual Apps and Desktops solutions and related services, and anticipates that these solutions and future derivative solutions and product lines based upon this technology will continue to constitute a majority of its revenue. The Company could experience declines in demand for its Workspace solutions and other solutions, whether as a result of general economic conditions, the delay or reduction in technology purchases, new competitive product releases, price competition, and lack of success of its strategic partners, technological change or other factors. Additionally, the Company's App Delivery and Security products generate revenues from a limited number of customers. As a result, if the App Delivery and Security product grouping loses certain customers or one or more such customers significantly decreases its orders, the Company's business, results of operations and financial condition could be adversely affected. Cost of Net Revenues Cost of subscription, support and services revenues consists primarily of compensation and other personnel-related costs of providing technical support, consulting and cloud capacity costs, as well as the costs related to providing the Company's offerings delivered via the cloud and hardware costs related to certain on-premise subscriptions offerings. Cost of product and license revenues consists primarily of hardware, royalties, product media and duplication, manuals, shipping expense, and packaging materials. In addition, the Company is a party to licensing agreements with various entities, which give the Company the right to use certain software code in its solutions or in the development of future solutions in exchange for the payment of fixed fees or amounts based upon the sales of the related product. Costs related to these agreements are included in Cost of net revenues. Also included in Cost of net revenues is amortization and impairment of product related intangible assets. Advertising Costs The Company expenses advertising costs as incurred. The Company has advertising agreements with, and purchases advertising from, online media providers to advertise its solutions. The Company also has strategic development funds and cooperative advertising agreements with certain distributors and resellers whereby the Company will reimburse distributors and resellers for qualified advertising of Company solutions. Reimbursement is made once the distributor, reseller or provider provides substantiation of qualified expenses. The Company estimates the impact of these expenses and recognizes them at the time of product sales as a reduction of net revenue in the accompanying consolidated statements of income. The total costs the Company recognized related to advertising were approximately $135.5 million, $118.4 million and $90.4 million, during the years ended December 31, 2021, 2020 and 2019, respectively. Income Taxes In the ordinary course of global business, there are transactions for which the ultimate tax outcome is uncertain; thus, judgment is required in determining the worldwide provision for income taxes. The Company provides for income taxes on transactions based on its estimate of the probable liability. The Company adjusts its provision as appropriate for changes that impact its underlying judgments. Changes that impact provision estimates include such items as jurisdictional interpretations on tax filing positions based on the results of tax audits and general tax authority rulings. The Company provides for global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries in the year the tax is incurred. Due to the evolving nature of tax rules combined with the large number of jurisdictions in which the Company operates, estimates of its tax liability and the realizability of its deferred tax assets could change in the future, which may result in additional tax liabilities and adversely affect the Company’s results of operations, financial condition and cash flows. Accounting for Stock-Based Compensation Plans The Company has various stock-based compensation plans for its employees and outside directors and accounts for stock-based compensation arrangements in accordance with the authoritative guidance, which requires the Company to measure and record compensation expense in its consolidated financial statements using a fair value method. The Company accounts for forfeitures as they occur. See Note 8 for further information regarding the Company’s stock-based compensation plans. Earnings per Share Basic earnings per share is calculated by dividing income available to stockholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted-average number of common and dilutive common share equivalents outstanding during the period. Dilutive common share equivalents consist of shares issuable upon the exercise or settlement of stock awards and shares issuable under the employee stock purchase plan (calculated using the treasury stock method) during the period they were outstanding and potential dilutive common shares from the conversion spread on the Company’s 0.500% Convertible Notes due 2019 (the “Convertible Notes”) and the Company's warrants during the period they were outstanding. The reconciliation of the numerator and denominator of the earnings per share calculation is presented in Note 15. Leases The Company leases certain office space and equipment under various leases. In addition to rent, the leases require the Company to pay for taxes, insurance, maintenance and other operating expenses. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, accrued expenses and other current liabilities, and operating lease liabilities in the Company’s consolidated balance sheets. Finance leases are included in p

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE The following is a description of the principal activities from which the Company generates revenue. Subscription Subscription revenues primarily consist of cloud-hosted offerings which provide customers a right to access one or more of the Company’s cloud-hosted subscription offerings, with routine customer support, as well as revenues from the Citrix Service Provider (“CSP”) program, on-premise subscription software licenses, and hybrid subscription offerings. The CSP program provides subscription-based services in which the CSP partners host software services to their end users. Product and license Product and license revenues are primarily derived from perpetual offerings related to the Company’s Workspace solutions and App Delivery and Security products. Support and services Support and services revenues include license updates, maintenance and professional services which are primarily related to the Company's perpetual offerings. License updates and maintenance revenues are primarily comprised of software and hardware maintenance, when and if-available updates and technical support. Services revenues are comprised of fees from consulting services primarily related to the implementation of the Company’s products and fees from product training and certification. The Company’s typical performance obligations include the following: Performance Obligation When Performance Obligation Subscription Cloud-hosted offerings Over the contract term, beginning on the date that service is made available to the customer (over time) CSP As the usage occurs (over time) On-premise subscription software licenses When software activation keys have been made available for download (point in time) On-premise subscription license updates and maintenance Ratably over the course of the service term (over time) Product and license Software licenses When software activation keys have been made available for download (point in time) Hardware When control of the product passes to the customer; typically upon shipment (point in time) Support and services License updates and maintenance for perpetual software licenses Ratably over the course of the service term (over time) Professional services As the services are provided (over time) Sales tax The Company records revenue net of sales tax. Timing of revenue recognition Year Ended December 31, 2021 2020 2019 (in thousands) Products and services transferred at a point in time $ 518,200 $ 813,525 $ 722,324 Products and services transferred over time 2,698,970 2,423,175 2,288,240 Total net revenues $ 3,217,170 $ 3,236,700 $ 3,010,564 Contract balances The Company's short-term and long-term contract assets, net of allowance for credit losses, were $46.6 million and $40.5 million, respectively, as of December 31, 2021, and $37.3 million and $41.7 million, respectively, as of December 31, 2020, and are included in Prepaid expenses and other current assets and Other assets, respectively, in the accompanying consolidated balance sheets. The Current portion of deferred revenues and the Long-term portion of deferred revenues were $1.71 billion and $329.5 million, respectively, as of December 31, 2021 and $1.51 billion and $392.4 million, respectively, as of December 31, 2020. The difference in the opening and closing balances of the Company’s contract assets and liabilities primarily results from the timing difference between the Company’s performance, and the Company's right to consideration or the customer’s payment. During the year ended December 31, 2021, the Company recognized $1.47 billion of revenue that was included in the deferred revenue balance as of December 31, 2020. During the year ended December 31, 2020, the Company recognized $1.33 billion of revenue that was included in the deferred revenue balance as of December 31, 2019. The Company performs its obligations under a contract with a customer by transferring solutions and services in exchange for consideration from the customer. Accounts receivable are recorded when the right to consideration becomes unconditional. The timing of the Company’s performance differs from the timing of the Company's right to consideration or the customer’s payment, which results in the recognition of a contract asset or a contract liability. The Company recognizes a contract asset when the Company transfers products or services to a customer and the right to consideration is conditional on something other than the passage of time. The Company recognizes a contract liability when it has received consideration or an amount of consideration is due from the customer and the Company has a future obligation to transfer products or services. The Company had no material asset impairment charges related to contract assets for the years ended December 31, 2021 and 2020, respectively. For the Company’s perpetual offerings, the timing of payment is typically upfront. Therefore, deferred revenue is created when a contract includes performance obligations such as license updates and maintenance or certain professional services that are satisfied over time. For subscription contracts, the timing of payment is typically in advance of services, and deferred revenue is amortized as these services are provided over time. For contracts that have an original duration of one year or less, the Company applies a practical expedient to determine whether a significant financing component exists and does not consider the effects of the time value of money. For multi-year contracts, the Company bills annually. Transaction price allocated to the remaining performance obligations The following table includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period (in thousands): <1-3 years 3-5 years 5 years or more Total Subscription $ 2,093,144 $ 92,477 $ 1,455 $ 2,187,076 Support and services 1,125,118 24,672 775 1,150,565 Total net revenues $ 3,218,262 $ 117,149 $ 2,230 $ 3,337,641

Credit Losses

Credit Losses	12 Months Ended

Credit Loss [Abstract]
CREDIT LOSSES	CREDIT LOSSES The Company is exposed to credit losses primarily through its accounts receivable, investments in available-for-sale debt securities, and contract assets. See Note 3 for additional information related to the Company's contract assets. Accounts receivable, net The Company’s accounts receivable are attributable primarily to direct sales to end customers and through VARs known as Citrix Solution Advisors, VADs, SIs, ISVs, OEMs and CSPs. Collateral is generally not required. The Company's accounts receivable consist of the following (in thousands): December 31, 2021 Accounts receivable, gross $ 918,590 Less: allowance for returns (12,542) Less: allowance for credit losses (20,737) Accounts receivable, net $ 885,311 The allowance for credit losses on accounts receivable is determined using a combination of specific reserves for accounts that are deemed to exhibit credit loss indicators and general reserves that are judgmentally determined using loss rates based on historical write-offs by geography and customer accounts subject to credit check versus non-credit check status and consideration of recent forecasted information, including underlying economic expectations. The credit loss reserves are updated quarterly for most recent write-offs and collections information and underlying economic expectations. The Company will compare its current estimate of expected credit losses with the estimate of credit losses from the prior period and will report in net income the amount necessary to adjust the allowance for current expected credit losses. Credit loss expense is included within General and administrative expenses in the accompanying consolidated statements of income. The activity in the Company's allowance for credit losses for the year ended December 31, 2021 is summarized as follows (in thousands): Total Balance of allowance for credit losses at January 1, 2021 $ 15,419 Current period provision for expected losses 8,667 Write-offs charged against allowance (3,460) Recoveries of any amounts previously written off 111 Balance of allowance for credit losses at December 31, 2021 $ 20,737 If the financial condition of a significant customer were to deteriorate, the Company’s operating results could be adversely affected. As of December 31, 2021 and 2020, one distributor accounted fo r 16% and 19%, respectively, of the Company's total gross accounts receivable. Available-for-sale Investments The Company did not have any credit loss expense recorded related to available-for-sale debt securities for the years ended December 31, 2021 and 2020, respectively. The Company has available-for-sale debt securities that have fair values below amortized cost; however, the Company does not consider a credit allowance necessary as (i) the Company does not intend to sell the securities, (ii) it is not more-likely-than-not that the Company will be required to sell the investments before recovery of the amortized cost basis, and (iii) the unrealized losses are due to market factors rather than credit loss factors. See Note 5 for more information on

Fair Value Disclosures [Abstract]
INVESTMENTS AND FAIR VALUE MEASUREMENTS	INVESTMENTS AND FAIR VALUE MEASUREMENTS Investments Available-for-sale Investments The Company's short-term available-for-sale debt investments are measured to fair value on a recurring basis. Unrealized gains and losses related to the Company’s short-term investments are recorded in Other comprehensive loss and are generally due to interest rate fluctuations. The securities that are in an unrealized loss position are reviewed on an individual basis in order to evaluate if all or a portion of the unrealized loss is a result of a credit loss. For impairment indicators due to credit loss factors, the Company establishes an allowance for credit losses with a charge to current period net income. See Note 4 for additional information regarding the credit losses for available-for-sale investments. As of December 31, 2021 and 2020, unrealized gains and losses from the Company’s available-for-sale investments were not material and the amortized cost approximated their fair value. For the year ended December 31, 2021 and 2020, the Company had no realized gains or losses on available-for-sale investments. The average remaining maturities of the Company’s short-term and long-term available-for-sale investments at December 31, 2021 were approximately five months and two years, respectively. Equity Securities without Readily Determinable Fair Values The Company held direct investments in privately-held companies of approximately $24.4 million and $22.5 million as of December 31, 2021, and 2020, respectively, which are accounted for at cost, less impairment plus or minus adjustments Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis As of December 31, 2021 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Assets: Cash and cash equivalents: Cash $ 425,650 $ 425,650 $ — $ — Money market funds 70,893 70,893 — — Corporate securities 17,450 — 17,450 — Available-for-sale securities: Corporate securities 27,940 — 27,440 500 Prepaid expenses and other current assets: Foreign currency derivatives 741 — 741 — Total assets $ 542,674 $ 496,543 $ 45,631 $ 500 Accrued expenses and other current liabilities: Foreign currency derivatives 1,531 — 1,531 — Total liabilities $ 1,531 $ — $ 1,531 $ — As of December 31, 2020 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in thousands) Assets: Cash and cash equivalents: Cash $ 375,874 $ 375,874 $ — $ — Money market funds 23,089 23,089 — — Corporate securities 166,436 — 166,436 — Government securities 187,496 — 187,496 — Available-for-sale securities: Agency securities 3,300 — 3,300 — Corporate securities 70,684 — 70,184 500 Government securities 64,494 — 64,494 — Prepaid expenses and other current assets: Foreign currency derivatives 4,012 — 4,012 — Total assets $ 895,385 $ 398,963 $ 495,922 $ 500 Accrued expenses and other current liabilities: Foreign currency derivatives 1,447 — 1,447 — Total liabilities $ 1,447 $ — $ 1,447 $ — The Company’s investment policy is designed to limit exposure to any one issuer depending on credit quality. The Company’s fixed income available-for-sale security portfolio generally consists of investment grade securities from diverse issuers with a minimum credit rating of A-/A3 and a weighted-average credit rating of AA-/Aa3. The Company values these securities based on pricing from the Service, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value, and accordingly, the Company classifies the majority of its fixed income available-for-sale securities as Level 2. The Company measures its cash flow hedges, which are classified as Prepaid expenses and other current assets and Accrued expenses and other current liabilities, at fair value based on indicative prices in active markets (Level 2 inputs). See Note 14 for further information regarding the Company's derivatives. Additional Disclosures Regarding Fair Value Measurements The carrying value of accounts receivable, accounts payable and accrued expenses approximate their fair value due to the short maturity of these items. As of December 31, 2021, the fair value of the $750.0 million unsecured senior notes due March 1, 2030 (the “2030 Notes”), $750.0 million of unsecured senior notes due December 1, 2027 (the “2027 Notes”) and $750.0 million of unsecured senior notes due March 1, 2026 (the “2026 Notes”) were determined based on inputs that are observable in the market (Level 2). Based on the closing trading price per $100 as of the last day of trading for the year ended December 31, 2021, the fair value of these instruments was as follows (in thousands): Fair Value Carrying Value 2030 Notes $ 763,418 $ 740,287 2027 Notes $ 814,148 $ 744,707 2026 Notes $ 730,110 $ 742,872 The Company also has variable debt instruments indexed to 1-Month LIBOR that resets monthly and the fair values of these instruments approximate the carrying value as of December 31, 2021.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS 2021 Business Combination On February 26, 2021 (the “Closing Date”), the Company completed the acquisition of Wrangler Topco, LLC (“Wrangler”), the parent entity of Wrike, Inc. (“Wrike”), a leader in the SaaS collaborative work management space, for approximately $2.07 billion (the “Purchase Consideration”). The Purchase Consideration consists of a base purchase price of $2.25 billion and is subject to certain adjustments as provided for under the related Agreement and Plan of Merger dated January 16, 2021 (the “Wrike Agreement”). The Company expects that the addition of Wrike’s cloud-delivered capabilities will expand its collaborative work management capabilities. Under the Wrike Agreement, the Company acquired all of the issued and outstanding equity securities of Wrangler. On the Closing Date, $35.0 million of the Purchase Consideration was deposited into a third-party escrow fund, to be held for up to one year following the Closing Date, to fund (i) potential payment obligations of Wrangler equityholders with respect to post-closing adjustments to the Purchase Consideration and (ii) potential post-closing indemnification obligations of Wrangler equityholders, in each case in accordance with the terms of the Wrike Agreement. Under the terms of the Wrike Agreement, certain unvested stock options held by Wrike employees were assumed by the Company and converted into options to purchase 526,113 shares of the Company's common stock that were valued at $54.3 million using the Black-Scholes option-pricing model. The portion of the fair value of the assumed stock options associated with pre-combination service of Wrike employees was valued at $28.9 million and represented a component of the Purchase Consideration. The remaining fair value of $25.4 million will be recognized as post-combination stock-based compensation expense over the service period. Of these assumed awards, 180,003 options continued with the same monthly vesting conditions under which they were originally granted. The majority of the remaining assumed options were reset to primarily cliff vest on December 31, 2021 or annually over two years. See Note 8 for detailed information on the assumed stock options. The Wrike Agreement contains representations, warranties and covenants believed to be customary for a transaction of this nature, including covenants as to indemnification for breaches of certain representations, warranties and covenants, subject to certain exclusions and caps. The Company has obtained a representation and warranty insurance policy under which it may seek coverage for breaches of certain of Wrangler’s representations, warranties, and covenants in the Wrike Agreement. The Company incurred $19.8 million of expenses related to the Wrike acquisition, of which $16.5 million and $3.3 million were expensed during the years ended December 31, 2021 and 2020, respectively, and are included in General and administrative expense in the accompanying consolidated statements of income. In February 2021, the Company entered into a three-year term loan credit agreement providing for a $1.00 billion senior unsecured term loan (the “2021 Term Loan”) and issued $750.0 million of the 2026 Notes. The proceeds of the 2021 Term Loan and the 2026 Notes were used to (i) fund a portion of the purchase price of the acquisition and (ii) to pay fees and expenses incurred in connection with the acquisition. The Company incurred $9.1 million of issuance costs that were netted against Long-term debt in the accompanying consolidated balance sheets. See Note 13 for detailed information on the debt financing. The Company has included the effect of the acquisition in its results of operations prospectively from the date of acquisition. Net revenues of Wrike included in the Company’s consolidated statements of income from the Closing Date through December 31, 2021 were $107.9 million. Loss from operations of Wrike included in the Company's consolidated statements of income from the Closing Date through December 31, 2021 was $189.0 million, primarily as a result of amortization of intangible assets acquired and stock-based compensation associated with the assumed options and the 2021 Inducement Plan. See Note 8 for detailed information on the 2021 Inducement Plan. Purchase Accounting for Wrike The purchase price for Wrike was allocated to the acquired net tangible and intangible assets based on estimated fair values as of the date of acquisition. The allocation of the total purchase price is summarized below (in thousands): Wrike Purchase Price Allocation Asset Life Current assets $ 32,008 Intangible assets 824,900 2 - 7 years Goodwill 1,602,384 Indefinite Other assets 17,681 Assets acquired 2,476,973 Current liabilities assumed 85,368 Long-term liabilities assumed 202,511 Deferred tax liabilities, non-current 122,402 Net assets acquired $ 2,066,692 The fair values of Wrike's intangible assets were determined using the income approach with significant inputs that are not observable in the market. Key assumptions include, but are not limited to, the expected future cash flows, the timing of the expected future cash flows, royalty rates, customer churn, technology obsolescence and the discount rates consistent with the level of risk. Current assets acquired in connection with the acquisition consisted primarily of cash, accounts receivable and other short term assets. Current liabilities assumed in connection with the acquisition consisted primarily of the current portion of deferred revenues, accounts payable and other accrued expenses, such as transaction expenses. The accrued transaction expenses were paid in full subsequent to the acquisition date. Long-term liabilities assumed in connection with the acquisition consisted of the long-term portion of deferred revenue, other long-term liabilities, and long-term debt, which was paid in full subsequent to the acquisition date. The Company continues to evaluate certain assets and liabilities, which encompass primarily deferred taxes related to the Wrike acquisition. Additional information, which existed as of the acquisition date but was at that time unknown to the Company, may become known to the Company during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. The Company estimated its obligation related to deferred revenue using the cost build-up approach. The cost build-up approach determines fair value by estimating the costs relating to supporting the obligation plus an assumed profit. The sum of the costs and assumed profit approximates the amount that the Company would be required to pay a third party to assume the obligation. The estimated costs to fulfill the obligation were based on the near-term projected cost structure for various revenue contracts, resulting in an adjustment to reduce Wrike's carrying value of deferred revenue. The acquired deferred revenue of $33.2 million represents the Company's estimate of the fair value of the contractual obligations assumed. The goodwill related to the acquisition is not deductible for tax purposes and is comprised primarily of expected synergies from combining operations and other intangible assets that do not qualify for separate recognition. Identifiable intangible assets acquired in connection with the Wrike acquisition (in thousands) and the weighted-average lives are as follows: Wrike Asset Life Core and product technologies $ 347,900 6 years Customer relationships 446,400 7 years Backlog 13,500 2 years Trade names 17,100 3 years Total $ 824,900 The following unaudited pro-forma information combines the consolidated results of the operations of the Company and Wrike as if the acquisition had occurred on January 1, 2020, the first day of the Company's fiscal year 2020 (in thousands, except per share data): Year Ended December 31, 2021 2020 Revenues $ 3,239,423 $ 3,340,730 Income from operations $ 207,941 $ 402,620 Net income $ 279,314 $ 304,195 Earnings per share - basic $ 2.25 $ 2.46 Earnings per share - diluted $ 2.21 $ 2.41

Share-based Payment Arrangement [Abstract]
EMPLOYEE STOCK-BASED COMPENSATION AND BENEFIT PLANS	EMPLOYEE STOCK-BASED COMPENSATION AND BENEFIT PLANS Plans The Company’s stock-based compensation program is a long-term retention program that is intended to attract and reward talented employees and align stockholder and employee interests. As of December 31, 2021, the Company had three stock-based compensation plans with shares available for grant. The Company is currently granting stock-based awards from its Second Amended and Restated 2014 Equity Incentive Plan (the “2014 Plan”), which was amended at the Company's Annual Meeting of Stockholders on June 3, 2020. Pursuant to the June 2020 amendment, the maximum number of shares of common stock available for issuance under the 2014 Plan was increased to 51,300,000. In addition, the amendment extended the term of the 2014 Plan to June 3, 2030 and updated the vesting provisions from monthly to annual vesting for annual director awards, consistent with the Company's current compensation program for non-employee directors. Under the terms of the 2014 Plan, the Company is authorized to grant incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), non-vested stock, non-vested stock units, stock appreciation rights (“SARs”), and performance units and to make stock-based awards to full and part-time employees of the Company and its subsidiaries or affiliates, where legally eligible to participate, as well as to consultants and non-employee directors of the Company. ISOs, NSOs, and SARs are not currently being granted. Under the 2014 Plan, stock options must be granted at exercise prices no less than fair market value on the date of grant. Non-vested stock awards may be granted for such consideration in cash, other property or services, or a combination thereof, as determined by the Company’s Compensation Committee of its Board of Directors. Stock-based awards are generally exercisable or issuable upon vesting. The Company’s policy is to recognize compensation cost for awards with only service conditions and a graded vesting schedule on a straight-line basis over the requisite service period for the entire award. As of December 31, 2021, there were 15,490,080 shares of common stock reserved for issuance under the 2014 Plan, including authorization to grant stock-based awards covering 10,830,292 shares of common stock. In connection with the Wrike acquisition, on February 26, 2021, the Company's Board of Directors adopted the 2021 Inducement Plan (the “2021 Inducement Plan”). The 2021 Inducement Plan provides for the grant of equity awards to induce highly-qualified prospective officers and employees to accept employment and to provide them with a proprietary interest in the Company. The Company is authorized to issue 320,000 shares of common stock for inducement awards under the 2021 Inducement Plan. During the year ended December 31, 2021, the Company granted 271,678 non-vested stock units to Wrike employees who joined the Company which vest based on service over a three-year term. As of December 31, 2021, there were 304,952 shares of common stock reserved for issuance pursuant to the 2021 Inducement Plan, including authorization under the 2021 Inducement Plan to grant stock-based awards covering 48,322 shares of common stock. Effective February 26, 2021, the Company assumed the Wrangler Topco, LLC Second Amended and Restated 2018 Equity Incentive Plan (the “Wrangler Plan”) and the Wrike, Inc. Amended and Restated 2013 Stock Plan (the “Wrike Plan”). As of December 31, 2021, there were 694,385 shares of the Company’s common stock reserved and authorized for issuance under the terms of the Wrangler Plan, including authorization under the Wrangler Plan to grant stock-based awards covering 325,622 shares of common stock. As of December 31, 2021, there were 142,267 shares of the Company's common stock reserved and authorized for issuance under the terms of the Wrike Plan. All of the Wrike Plan awards are currently outstanding with no new shares available for issuance. ESPP The 2015 Employee Stock Purchase Plan (the “2015 ESPP”), was approved at the Company’s Annual Meeting of Stockholders on May 28, 2015. Under the 2015 ESPP, all full-time and certain part-time employees of the Company are eligible to purchase common stock of the Company twice per year at the end of a six-month payment period (a “Payment Period”). During each Payment Period, eligible employees who so elect may authorize payroll deductions in an amount no less than 1% nor greater than 10% of his or her base pay for each payroll period in the Payment Period. At the end of each Payment Period, the accumulated deductions are used to purchase shares of common stock from the Company up to a maximum of 12,000 shares for any one employee during a Payment Period. Shares are purchased at a price equal to 85% of the fair market value of the Company’s common stock, on either the first business day of the Payment Period or the last business day of the Payment Period, whichever is lower. Employees who, after exercising their rights to purchase shares of common stock in the 2015 ESPP, would own shares representing 5% or more of the voting power of the Company’s common stock, are ineligible to continue to participate under the 2015 ESPP. The 2015 ESPP provides for the issuance of a maximum of 16,000,000 shares of common stock. As of December 31, 2021, 3,189,988 shares have been issued under the 2015 ESPP. The Company recorded stock-based compensation costs related to its employee stock purchase plan of $17.6 million, $12.6 million and $12.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company used the Black-Scholes model to estimate the fair value of the 2015 ESPP awards with the following weighted-average assumptions: Year Ended December 31, 2021 2020 2019 Expected volatility factor 0.27 - 0.35 0.21 - 0.35 0.22 - 0.29 Risk free interest rate 0.05% - 0.13% 0.13% - 2.06% 2.06% - 2.49% Expected dividend yield 0.92% - 1.27% 0.92% - 1.39% 1.27% - 1.39% Expected life (in years) 0.5 0.5 0.5 The Company determined the expected volatility factor by considering the implied volatility in six-month market-traded options of the Company's common stock based on third party volatility quotes. The Company's decision to use implied volatility was based upon the availability of actively traded options on the Company's common stock and its assessment that implied volatility is more representative of future stock price trends than historical volatility. The risk-free interest rate was based on a U.S. Treasury instrument whose term is consistent with the expected term of the stock options. The current dividend yield has been updated for expected dividend yield payout. The expected term is based on the term of the purchase period for grants made under the ESPP. Non-Vested Stock Units Service-Based Stock Units The Company awards senior level employees and certain other employees non-vested stock units granted under the 2014 Plan that vest based on service. These non-vested stock unit awards primarily vest 33.33% on each of the first, second, and third anniversary subsequent to the grant date of the award. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. In addition, the Company awards non-vested stock units to all of its continuing non-employee directors, which represent the right to receive one share of the Company's common stock upon vesting. Awards granted to non-employee directors vest in full in one installment on the earlier of: (i) the first anniversary of the award date; or (ii) the day immediately prior to the Company’s next annual meeting of stockholders following the award date. Company Performance Stock Units On March 1, 2021, the Company awarded senior level employees 305,229 non-vested performance stock unit awards granted under the 2014 Plan. The number of non-vested performance stock units that ultimately vest will be determined within sixty days following completion of the performance period ending December 31, 2023 and will be based on the achievement of specific corporate financial performance goals related to the Company’s Software as a Service (SaaS) annualized recurring revenue (ARR) growth measured during the period from January 1, 2021 to December 31, 2023. The number of non-vested stock units issued will be based on a graduated slope, with the maximum number of non-vested stock units issuable pursuant to the award capped at 200% of the target number of non-vested stock units set forth in the award agreement. Additionally, the awards have an explicit adjustment mechanism to prevent the attainment rates from being distorted should a material acquisition other than Wrike occur during the performance period. The Company is required to estimate the attainment expected to be achieved related to the defined performance goals and the number of non-vested stock units that will ultimately be awarded in order to recognize compensation expense over the vesting period. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. Compensation expense will be recorded through the end of the performance period on December 31, 2023 if it is deemed probable that the performance goals will be met. If the performance goals are not met, no compensation cost will be recognized and any previously recognized compensation cost will be reversed. On April 1, 2020, the Company awarded senior level employees 294,605 non-vested performance stock unit awards granted under the 2014 Plan. The number of non-vested performance stock units that ultimately vest will be determined within sixty days following completion of the performance period ending December 31, 2022 and will be based on the achievement of specific corporate financial performance goals related to the Company’s ARR growth measured during the period from January 1, 2020 to December 31, 2022. The number of non-vested stock units issued will be based on a graduated slope, with the maximum number of non-vested stock units issuable pursuant to the award capped at 200% of the target number of non-vested stock units set forth in the award agreement. The Company is required to estimate the attainment expected to be achieved related to the defined performance goals and the number of non-vested stock units that will ultimately be awarded in order to recognize compensation expense over the vesting period. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. Compensation expense is being recorded through the end of the performance period on December 31, 2022 if it is deemed probable that the performance goals will be met. If the performance goals are not met, no compensation cost will be recognized and any previously recognized compensation cost will be reversed. On April 6, 2020, the Company awarded certain senior level employees 90,756 non-vested performance stock unit awards granted under the 2014 Plan that vested based on the Company’s ARR growth during the relevant performance periods, which spanned January 1, 2020 through December 31, 2021. The number of non-vested stock units issued upon the vesting of the award will be based on a graduated slope, with the maximum number of non-vested stock units issuable pursuant to the award capped at 125% of the target number of non-vested stock units set forth in the award agreement. The Company was required to estimate the attainment expected to be achieved related to the defined performance goals and the number of non-vested stock units that would ultimately be awarded in order to recognize compensation expense over the vesting period. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. Half of these awards vested on December 31, 2020, which corresponds to the award’s interim performance period, and met the underlying performance metrics. The final payout approval related to these awards was obtained within sixty days of the vesting date in accordance with the award provisions. The remaining awards vested on December 31, 2021, and the underlying performance metrics were met. Accordingly, compensation expense on those unvested awards was recorded through December 31, 2021. The final payout approval related to the awards was obtained within sixty days of the vesting date in accordance with the award provisions. In April 2019, the Company awarded senior level employees 293,991 non-vested performance stock unit awards granted under the 2014 Plan. The number of non-vested stock units underlying the award will be determined within sixty days following completion of the performance period ending December 31, 2021 and was based on the achievement of specific corporate financial performance goals related to subscription bookings as a percentage of total subscription and product bookings measured during the period from January 1, 2021 to December 31, 2021. The number of non-vested stock units issued will be based on a graduated slope, with the maximum number of non-vested stock units issuable pursuant to the award capped at 200% of the target number of non-vested stock units set forth in the award agreement. The Company was required to estimate the attainment expected to be achieved related to the defined performance goals and the number of non-vested stock units that would ultimately be awarded in order to recognize compensation expense over the vesting period. Each non-vested stock unit, upon vesting, represents the right to receive one share of the Company’s common stock. These awards met the underlying performance metrics and, therefore, vested on December 31, 2021. As a result, compensation expense was recorded through the end of the performance period. The final payout approval related to the awards was obtained within sixty days of the vesting date in accordance with the award provisions. In February 2019, the Company had awarded certain senior level employees 93,500 non-vested performance stock units granted under the 2014 Plan. The number of non-vested stock units underlying the award were based on the achievement of specific corporate financial performance goals between the fiscal years ended December 31, 2018 and December 31, 2020. In January 2020, the non-vested performance stock units were cancelled pursuant to a forfeiture agreement executed by each holder in return for nominal cash consideration. The impact of the cancellation was not material to the consolidated financial statements. In March 2018, the Company awarded senior level employees 268,729 non-vested performance stock unit awards granted under the 2014 Plan. The number of non-vested stock units underlying the award were based on the achievement of specific corporate financial performance goals related to subscription bookings as a percentage of total product bookings measured during the period from January 1, 2020 to December 31, 2020. These awards vested on December 31, 2020 and met the underlying performance metrics. As a result, compensation expense was recorded through the end of the performance period. The Company recorded stock-based compensation costs related to its company performance stock units of $48.1 million, $50.5 million and $40.2 million for the years ended December 31, 2021, 2020 and 2019, respectively. Modification of Market and Company Performance Stock Units On April 22, 2019, the change in control provisions of the unvested and outstanding February 2019 and March 2018 company performance stock unit awards were modified such that if a change in control were to occur prior to the end of the award’s performance period, the award would be deemed earned at 200% of the target award, subject to time-based vesting and the awardee’s continuous employment through the end of the award’s performance periods. Previously, the change in control provisions of these awards allowed for either pro rata vesting or vesting based on interim performance through the change in control date. No incremental compensation expense was recorded as a result of this modification given the improbable nature of a change in control event. Non-Vested Stock Unit Activity The following table summarizes the Company's non-vested stock unit activity for the year ended December 31, 2021: Number of Shares Weighted- Average Fair Value at Grant Date Non-vested stock units at December 31, 2020 5,185,045 $ 116.86 Granted 3,313,313 127.65 Vested (2,674,194) 109.46 Forfeited (929,454) 126.54 Non-vested stock units at December 31, 2021 4,894,710 $ 126.25 For the years ended December 31, 2021, 2020 and 2019, the Company recognized stock-based compensation expense of $315.1 million, $295.1 million and $266.5 million, respectively, over the vesting period of the respective stock units. The fair value of the stock units vested in 2021, 2020, and 2019 was $292.7 million, $260.0 million and $246.7 million, respectively. As of December 31, 2021, there was $398.6 million of total unrecognized compensation cost related to non-vested stock units. The unrecognized cost of the awards legally granted through December 31, 2021 is expected to be recognized over a weighted-average period of 1.65 years. Assumed Stock Options In connection with the acquisition of Wrike, the Company assumed 526,113 outstanding stock options which expire ten years from the date of grant. The following table summarizes stock option activity in connection with the acquisition of Wrike during the year ended December 31, 2021: Number of Weighted- Weighted Average Remaining Contractual Life Aggregate Intrinsic Value (in thousands) (1) Outstanding as of December 31, 2020 — $ — — Assumed from acquisitions 526,113 48.32 Exercised (23,998) 43.04 Forfeited or expired (19,443) 49.26 Outstanding as of December 31, 2021 482,672 48.54 0.80 $ 22,225 Vested or expected to vest 167,268 42.51 0.28 $ 8,711 Exercisable as of December 31, 2021 167,268 $ 42.51 0.28 $ 8,711 (1) The intrinsic value is calculated as the difference between the exercise price of the underlying stock option award and the closing market price of the Company’s common stock as of December 31, 2021. For the year ended December 31, 2021, the estimated weighted-average grant date fair value for the assumed stock options was $103.22 per share and total fair value of $54.3 million. For the year ended December 31, 2021, the Company recorded stock-based compensation costs related to unvested assumed stock options of $14.0 million. As of December 31, 2021, there was $10.5 million of total unrecognized compensation costs related to unvested assumed stock options to be recognized over a weighted-average period of 0.80 years. The following table summarizes the assumptions used in the Black-Scholes option-pricing model to determine the estimated fair value of the assumed stock options: Year Ended December 31, 2021 Expected volatility factor 0.51 - 0.75 Risk free interest rate 0.04% - 0.14% Expected dividend yield 1.11% Expected life (in years) 0.08 - 1.00 The Company determined the expected volatility factor by considering the implied volatility in various market-traded options of the Company's common stock based on third-party volatility quotes. The Company's decision to use implied volatility was based upon the availability of actively traded options on the Company's common stock and its assessment that implied volatility is more representative of future stock price trends than historical volatility. The risk-free interest rate was based on a U.S. Treasury instrument whose term is consistent with the expected term of the stock options. The current dividend yield has been updated for expected dividend yield payout. The expected term was based on the average period the stock options are expected to remain outstanding, generally calculated as the midpoint of the stock options’ remaining vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. See Note 6 for detailed information on the Wrike acquisition.

Equity [Abstract]
CAPITAL STOCK	CAPITAL STOCK Stock Repurchase Program The Company’s Board of Directors authorized a stock repurchase program, of which $1.00 billion was approved in January 2020. The objective of the Company’s stock repurchase program was to improve stockholders’ returns and mitigate earnings per share dilution posed by the issuance of shares related to employee equity compensation awards. At December 31, 2021, $625.6 million was available to repurchase common stock pursuant to the stock repurchase program. All shares repurchased were recorded as treasury stock. A portion of the funds used to repurchase stock over the course of the program was provided by net proceeds from debt, as well as proceeds from employee stock awards and the related tax benefit. While the Merger Agreement is in effect, the Company is prohibited from repurchasing shares of its common stock, including under the stock repurchase program. See Note 19 for detailed information on the Merger Agreement. On January 30, 2020, the Company used the proceeds from its Term Loan Credit Agreement and entered into accelerated share repurchase (“ASR”) transactions with a group of dealers for an aggregate of $1.00 billion. Under the ASR transactions, the Company received an initial share delivery of 6.5 million shares of its common stock, with the remainder delivered upon completion of the ASR transactions. The total number of shares of common stock that the Company repurchased under each ASR agreement was based on the average of the daily volume-weighted average prices of its common stock during the term of the applicable ASR agreement, less a discount. The Company received delivery of 0.8 million shares of its common stock in August 2020 in final settlement of the ASR Agreement. See Note 13 for detailed information on the Term Loan Credit Agreement. During the year ended December 31, 2021, the Company made no open market purchases under the stock repurchase program. In addition to the ASR, during the year ended December 31, 2020, the Company expended $288.5 million on open market purchases under the stock repurchase program, repurchasing 2.5 million shares of outstanding common stock at an average price of $116.40. During the year ended December 31, 2019, the Company expended $453.9 million on open market purchases under the stock repurchase program, repurchasing 4.5 million shares of outstanding common stock at an average price of $100.11. Shares for Tax Withholding During the years ended December 31, 2021, 2020 and 2019, the Company withheld 870,057 shares, 893,479 shares and 882,078 shares, respectively, from equity awards that vested. Amounts withheld to satisfy minimum tax withholding obligations that arose on the vesting of equity awards was $115.5 million, $121.7 million and $89.2 million, for 2021, 2020 and 2019, respectively. These shares are reflected as treasury stock in the Company's consolidated balance sheets and the related cash outlays do not reduce the Company's total stock repurchase authority. Preferred Stock The Company is authorized to issue 5,000,000 shares of preferred stock, $0.01 par value per share. No shares of such preferred stock were issued and outstanding at December 31, 2021 or 2020.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Matters The Company accrues a liability for legal contingencies when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of, or a range of, the loss. The Company reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. To the extent new information is obtained and the Company's views on the probable outcomes of any pending claims, suits, assessments, regulatory investigations, or other legal proceedings change, changes in the Company's accrued liabilities would be recorded in the period in which such determination is made. In addition, in accordance with the relevant authoritative guidance, for matters in which the likelihood of material loss is at least reasonably possible, the Company provides disclosure of the possible loss or range of loss. If a reasonable estimate cannot be made, however, the Company will provide disclosure to that effect. Due to the nature of the Company's business, the Company is subject to patent infringement claims, including current litigati on alleging infringement by various Company solutions and services. The Company believes that it has meritorious defenses to the allegations made in its pending litigation and intends to vigorously defend itself; however, it is unable currently to determine the ultimate outcome of these or similar matters or the potential exposure to loss, if any. In addition, the Company is subject to various other legal proceedings, including suits, assessments, regulatory actions and investigations generally arising out of the normal course of business. Although it is difficult to predict the ultimate outcomes of these matters, the Company believes that outcomes that will materially and adversely affect its business, financial position, results of operations or cash flows are reasonably possible but not estimable at this time. On November 19, 2021, a putative securities class action complaint was filed in the United States District Court for the Southern District of Florida on behalf of a putative class of persons and entities that purchased shares of Citrix common stock between January 22, 2020, and October 6, 2021. The complaint names the Company and certain of its current and former officers and directors as defendants and alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5, promulgated thereunder, based on allegedly false or misleading statements that failed to disclose that Citrix's Guarantees The authoritative guidance requires certain guarantees to be recorded at fair value and requires a guarantor to make disclosures, even when the likelihood of making any payments under the guarantee is remote. For those guarantees and indemnifications that do not fall within the initial recognition and measurement requirements of the authoritative guidance, the Company must continue to monitor the conditions that are subject to the guarantees and indemnifications, as required under existing generally accepted accounting principles, to identify if a loss has been incurred. If the Company determines that it is probable that a loss has been incurred, any such estimable loss would be recognized. The initial recognition and measurement requirements do not apply to the provisions contained in the majority of the Company’s software license agreements that indemnify licensees of the Company’s software from damages and costs resulting from claims alleging that the Company’s software infringes the intellectual property rights of a third party. The Company has not made material payments pursuant to these provisions. The Company has not identified any losses that are probable under these provisions and, accordingly, the Company has not recorded a liability related to these indemnification provisions. Purchase Obligations The Company has agreements with suppliers to purchase inventory and estimates its non-cancelable obligations under these agreements for the fiscal year ended December 31, 2022 to be $9.4 million. The Company also has contingent obligations to purchase inventory for the fiscal year ended December 31, 2022 of $37.3 million. The Company does not have any such purchase obligations beyond December 31, 2022. Other Purchase Commitments In May 2020, the Company entered into an amended agreement with a third-party provider, in the ordinary course of business, for the use of certain cloud services through June 2029. Under the amended agreement, the Company is committed to a purchase of $1.00 billion throughout the term of the agreement. As of December 31, 2021, the Company had $851.5 million of remaining obligations under the purchase agreement. In May 2021, the Company entered into an amended agreement with a third-party provider, in the ordinary course of business, for the use of certain cloud services through May 2024. Under the amended agreement, the Company is committed to purchase services under this agreement totaling $100.0 million over the term, with commitments of $32.0 million in fiscal year beginning 2021, $24.0 million in fiscal year beginning 2022, $24.0 million in fiscal year beginning 2023 and $20.0 million at any time over the three-year term. As of December 31, 2021, the Company had $54.5 million of remaining obligations under the purchase agreement.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is required to estimate its income taxes in each of the jurisdictions in which it operates as part of the process of preparing its consolidated financial statements. The Company maintains certain strategic management and operational activities in overseas subsidiaries and its foreign earnings are taxed at rates that are generally lower than in the United States. On March 11, 2021, the United States enacted the American Rescue Plan Act of 2021 (“American Rescue Plan Act”). The American Rescue Plan Act includes a wide variety of tax and non-tax provisions aimed to provide relief to individuals and businesses adversely affected by the COVID-19 pandemic. The American Rescue Plan Act also expands the limitation on deductions publicly-held companies may take with respect to certain employee compensation effective for tax years beginning after December 31, 2026. Although the Company is evaluating the impact of global COVID-19-related proposed and enacted legislation, as of the end of the current period no material impact to the Company's financial results is expected. The Company will continue to review and evaluate any future guidance, developments, or legislation issued by applicable tax authorities. On May 19, 2019, Swiss voters approved the Federal Act on Tax Reform and AHV Financing (“TRAF”), which provides for broad changes to federal and cantonal taxation in Switzerland effective January 1, 2020. The TRAF requires the abolishment of certain favorable tax regimes, provides for certain transitional relief, and directs the cantons to implement certain mandatory measures while other provisions are at the discretion of the canton. During the period ended December 31, 2019, the cantonal authority provided its guidance for the cantonal tax implications of the TRAF. As a result of the TRAF and the accompanying guidance from the Swiss taxing authorities, the Company recorded a deferred tax asset and related tax benefits of $145.6 million and $99.9 million attributable to the cantonal and federal impact of the TRAF, respectively. The Company also recorded a valuation allowance of $33.5 million to reduce the cantonal deferred tax asset as it was not more likely than not the cantonal deferred tax asset will be fully realized. During the period ended December 31, 2021 , the Swiss taxing authorities, including the canton, issued final rulings that contained revised guidance addressing certain implications of the TRAF. As a result, the Company recorded a benefit of $83.5 million attributable to the federal and cantonal impact of the updated rulings as well as a benefit of $36.9 million related to the release of the valuation allowance on the cantonal deferred tax asset as it is now more likely than not the cantonal deferred tax asset will be fully realized due to the revised cantonal ruling. The Company will continue to review and evaluate any future guidance, developments, or legislation issued by the Swiss taxing authorities.

At December 31, 2021, the Company determined a $122.5 million valuation allowance was necessary, which relates to deferred tax assets for net operating losses and tax credits. At December 31, 2021, the Company retained $370.4 million of remaining net operating loss carry forwards in the United States from acquisitions. The utilization of these net operating loss carry forwards are limited in any one year pursuant to Internal Revenue Code Section 382 and may begin to expire in 2022. At December 31, 2021, the Company held $116.7 million of remaining net operating loss carry forwards in foreign jurisdictions that begin to expire in 2023. At December 31, 2021, the Company held $228.6 million of federal and state research and development tax credit carry forwards in the United States, a portion of which may begin to expire in 2022. A reconciliation of the Company’s effective tax rate to the statutory federal rate is as follows: Year Ended December 31, 2021 2020 2019 Federal statutory taxes 21.0 % 21.0 % 21.0 % State income taxes, net of federal tax benefit (5.5) 0.3 0.3 Foreign operations 1.9 (5.1) (5.8) Permanent differences 6.2 2.2 3.0 Tax reform - Switzerland (49.9) — (48.2) Favorable impact from tax ruling (11.6) — — Change in valuation allowance reserve (21.0) 3.4 7.4 Tax credits (29.3) (8.1) (8.4) Stock-based compensation (5.1) (3.0) (1.9) Change in accruals for uncertain tax positions 11.1 (2.5) (1.1) Other (1.8) 0.9 (0.1) (84.0) % 9.1 % (33.8) % The Company’s effective tax rate generally differs from the U.S. federal statutory rate primarily due to lower tax rates on earnings generated by the Company’s foreign operations that are taxed primarily in Switzerland. The Company's effective tax rate was approximately (84.0)% and 9.1% for the years ended December 31, 2021 and 2020, respectively. The decrease in the effective tax rate when comparing the year ended December 31, 2021 to the year ended December 31, 2020, was primarily due to an income tax benefit of $120.4 million due to final rulings issued by the Swiss taxing authorities that provided revised guidance related to certain provisions of the TRAF. The Company's effective tax rate was approximately 9.1% and (33.8)% for the years ended December 31, 2020 and 2019, respectively. The increase in the effective tax rate when comparing the year ended December 31, 2020 to the year ended December 31, 2019, was primarily due to tax items unique to the period ended December 31, 2019. These amounts include an estimated income tax benefit of $112.1 million and $99.9 million attributable to the cantonal and federal impact of the TRAF, respectively, during the year ended December 31, 2019. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2021, 2020 and 2019 is as follows (in thousands): Balance at December 31, 2018 $ 89,906 Additions based on tax positions related to the current year 11,244 Additions for tax positions of prior years 3,414 Reductions related to the expiration of statutes of limitations (20,098) Balance at December 31, 2019 84,466 Additions based on tax positions related to the current year 15,182 Additions for tax positions of prior years 13,765 Reductions related to the expiration of statutes of limitations (15,553) Reductions related to audit settlements (19,975) Reductions for tax positions of prior years (3,203) Balance at December 31, 2020 74,682 Additions based on tax positions related to the current year 16,949 Additions for tax positions of prior years 11,913 Reductions related to the expiration of statutes of limitations (2) Balance at December 31, 2021 $ 103,542 As of December 31, 2021, the Company's unrecognized tax benefits totaled approximately $103.5 million compared to $74.7 million as o f December 31, 2020. At December 31, 2021, $89.5 million included in the balance for tax positions would affect the annual effective tax rate if recognized. The Company recognizes interest accrued related to uncertain tax positions and penalties in income tax expense. As of December 31, 2021, the Company has accrued $1.6 million for the payment of interest. The Company and one or more of its subsidiaries are subject to U.S. federal income taxes in the United States, as well as income taxes of multiple state and foreign jurisdictions. The Company is currently under examination by the United States Internal Revenue Service for the 2017 and 2018 tax years. With few exceptions, the Company is generally not subject to examination for state and local income tax, or in non-U.S. jurisdictions by tax authorities for years prior to 2017. The Company's U.S. liquidity needs are currently satisfied using cash flows generated from its U.S. operations, borrowings, or both. The Company also utilizes a variety of tax planning strategies in an effort to ensure that its worldwide cash is available in locations in which it is needed. The Company expects to repatriate a substantial portion of its foreign earnings over time, to the extent that the foreign earnings are not restricted by local laws or result in significant incremental costs associated with repatriating the foreign earnings.

The 2021 Term Loan Credit Agreement provided the Company with a facility to borrow a term loan on an unsecured basis in an aggregate principal amount of up to $1.00 billion. The Company borrowed $1.00 billion on February 26, 2021 under the 2021 Term Loan, and the loan matures on February 26, 2024. The proceeds of borrowings under the 2021 Term Loan Credit Agreement were used to finance a portion of the purchase price for the Wrike acquisition. See Note 6 for detailed information on the Wrike acquisition. Borrowings under the 2021 Term Loan Credit Agreement bear interest at a rate equal to (a) either (i) a customary LIBOR formula or, upon a phase-out of LIBOR, an alternative benchmark rate as provided in the 2021 Term Loan Credit Agreement, or (ii) a customary base rate formula, plus (b) the applicable margin with respect thereto, which initially was determined based on the Company’s consolidated leverage ratio. The Company made an election to base the applicable margin on the Company’s non-credit enhanced, senior unsecured long-term debt rating as determined by Moody’s Investors Service, Inc., Standard & Poor’s Financial Services, LLC and Fitch Ratings Inc., in each case as set forth in the 2021 Term Loan Credit Agreement effective in the third quarter of 2021. The 2021 Term Loan Credit Agreement includes a covenant limiting the Company’s consolidated leverage ratio to not more than 4.0:1.0, subject to a mandatory step-down after the fiscal quarter ending March 31, 2022 to 3.75:1.0, and further subject to, upon the occurrence of a qualified acquisition in any quarter on or after the fiscal quarter ending March 31, 2022, if so elected by the Company, a step-up to 4.25:1.0 for the four fiscal quarters following such qualified acquisition. The 2021 Term Loan Credit Agreement also includes a covenant limiting the Company’s consolidated interest coverage ratio to not less than 3.0:1.0. The 2021 Term Loan Credit Agreement includes customary events of default, with corresponding grace periods in certain circumstances, including, without limitation, payment defaults, cross-defaults, the occurrence of a change of control of the Company and bankruptcy-related defaults. The 2021 Lenders are entitled to accelerate repayment of the loans under the 2021 Term Loan Credit Agreement upon the occurrence of any of the events of default. In addition, the 2021 Term Loan Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the ability of the Company to grant liens, merge or consolidate, dispose of all or substantially all of its assets, change its business and incur subsidiary indebtedness, in each case subject to customary exceptions. The 2021 Term Loan Credit Agreement also contains representations and warranties customary for an unsecured financing of this type. The Company was in compliance with these covenants as of December 31, 2021. Certain 2021 Lenders and/or their affiliates have provided and may continue to provide commercial banking, investment management and other services to the Company, its affiliates and employees, for which they receive customary fees and commissions. Term Loan Credit Agreement On January 21, 2020, the Company entered into a Term Loan Credit Agreement with Bank of America, N.A., as administrative agent, and the other lenders party thereto from time to time (the “Term Loan Credit Agreement”) that provides the Company with facilities to borrow term loans on an unsecured basis in an aggregate principal amount of up to $1.00 billion, consisting of (i) a $500.0 million 364-day term loan facility (the “364-day Term Loan”), and (ii) a $500.0 million 3-year term loan (the “3-year Term Loan”), in each case in a single borrowing, subject to satisfaction of certain conditions set forth in the Term Loan Credit Agreement. On January 30, 2020, the Company borrowed $1.00 billion under the term loans and used the proceeds to enter into the accelerated share repurchase transactions for an aggregate of $1.00 billion. During the first quarter of 2020, the Company used the net proceeds from the 2030 Notes and cash to repay $750.0 million under the Term Loan Credit Agreement. In the third quarter of 2021, the Company repaid $150.0 million under the 3-year Term Loan. See Note 9 for detailed information on the accelerated share repurchase. Borrowings under the Term Loan Credit Agreement bear interest at a rate equal to (a) either (i) LIBOR or, upon a phase-out of LIBOR, an alternative benchmark rate as provided in the Term Loan Credit Agreement, or (ii) a customary base rate formula, plus (b) the applicable margin with respect thereto, which initially was determined based on the Company’s consolidated leverage ratio. The Company made an election to base the applicable margin on the Company’s non-credit enhanced, senior unsecured long-term debt rating as set forth in the Term Loan Credit Agreement effective in the second quarter of 2021. On February 5, 2021, the Company entered into the first amendment to the Term Loan Credit Agreement, which amends, among other things, the covenant limiting the Company’s consolidated leverage ratio. After giving effect to the amendment, the covenant limiting the Company's consolidated leverage ratio will be consistent with the covenant limiting the Company's consolidated leverage ratio in the 2021 Term Loan Credit Agreement, and will be limited to not more than 4.0:1.0, subject to a mandatory step-down after the fiscal quarter ending March 31, 2022 under the 2021 Term Loan Credit Agreement (the “Leverage Ratio Step-Down”) to 3.75:1.0, and further subject to, upon the occurrence of a qualified acquisition in any quarter on or after the fifth fiscal quarter ending after the Leverage Ratio Step-Down, if so elected by the Company, a step-up to 4.25:1.0 for the four fiscal quarters following such qualified acquisition. The Company was in compliance with these covenants as of December 31, 2021. Senior Notes On February 18, 2021, the Company issued $750.0 million of unsecured senior notes due March 1, 2026. The 2026 Notes accrue interest at a rate of 1.250% per annum, which is due semi-annually on March 1 and September 1 of each year beginning on September 1, 2021. The net proceeds from this offering were $741.4 million, after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company used the net proceeds from the 2026 Notes to fund a portion of the purchase price for the Wrike acquisition. The 2026 Notes will mature on March 1, 2026, unless earlier redeemed in accordance with their terms prior to such date. On February 25, 2020, the Company issued $750.0 million of unsecured senior notes due March 1, 2030. The 2030 Notes accrue interest at a rate of 3.300% per annum. Interest on the 2030 Notes is due semi-annually on March 1 and September 1 of each year. The net proceeds from this offering were $738.1 million, after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company used the net proceeds from the 2030 Notes and cash to repay $500.0 million under the 364-day Term Loan and $250.0 million under the 3-year Term Loan. The 2030 Notes will mature on March 1, 2030, unless earlier redeemed in accordance with their terms prior to such date. On November 15, 2017, the Company issued $750.0 million of unsecured senior notes due December 1, 2027. The 2027 Notes accrue interest at a rate of 4.500% per annum. Interest on the 2027 Notes is due semi-annually on June 1 and December 1 of each year. The net proceeds from this offering were approximately $741.0 million, after deducting the underwriting discount and estimated offering expenses payable by the Company. Net proceeds from this offering were used to repurchase shares of the Company's common stock through an ASR transaction which the Company entered into with Citibank, N.A. (the “ASR Counterparty”) on November 13, 2017. The 2027 Notes will mature on December 1, 2027, unless earlier redeemed in accordance with their terms prior to such date. Each of the 2026 Notes, 2030 Notes and 2027 Notes are individually redeemable in whole or from time to time in part at the Company's option, subject to a make-whole premium. In addition, upon the occurrence of certain change of control triggering events prior to maturity, holders of the notes may require the Company to repurchase the notes for cash at a repurchase price of 101% of the principal amount of the notes to be repurchased plus accrued and unpaid interest to, but excluding, the repurchase date. Credit Facility On November 26, 2019, the Company entered into an amended and restated credit agreement (the “Credit Agreement”) with a group of financial institutions, which amends and restates the Company’s Credit Agreement, dated January 7, 2015. The Credit Agreement provides for a five-year unsecured revolving credit facility in the aggregate amount of $250.0 million, subject to continued covenant compliance. The Company may elect to increase the revolving credit facility by up to $250.0 million if existing or new lenders provide additional revolving commitments in accordance with the terms of the Credit Agreement. A portion of the revolving line of credit (i) in the aggregate amount of $25.0 million may be available for issuances of letters of credit and (ii) in the aggregate amount of $10.0 million may be available for swing line loans, as part of, not in addition to, the aggregate revolving commitments. The credit facility bears interest at a rate equal to (a) either (i) a LIBOR or, upon a phase-out of LIBOR, an alternative benchmark rate as provided in the Credit Agreement, or (ii) a customary base rate formula, plus (b) the applicable margin with respect thereto, which initially was determined based on the Company’s consolidated leverage ratio. The Company made an election to base the applicable margin on the Company’s long-term debt rating as set forth in the Credit Agreement effective in the second quarter of 2021. In addition, the Company is required to pay a quarterly facility fee ranging from 0.11% to 0.20% of the aggregate revolving commitments under the credit facility and based on the ratio of the Company’s total debt to the Company’s consolidated EBITDA or long-term credit rating. As of December 31, 2021 and 2020, no amounts were outstanding under the credit facility. On February 5, 2021, the Company entered into the first amendment to the Credit Agreement, which amends, among other things, the covenant limiting the Company’s consolidated leverage ratio. After giving effect to the amendment, the covenant limiting the Company’s consolidated leverage ratio will be consistent with the covenant limiting the Company’s consolidated leverage ratio in the 2021 Term Loan Credit Agreement, and will be limited to not more than 4.0:1.0, subject to a mandatory step-down after the fiscal quarter ending March 31, 2022 (or such earlier date as the Company may elect by written notice to Bank of America, N.A., in its capacity as administrative agent) under the 2021 Term Loan Credit Agreement (the “Leverage Ratio Step-Down”) to 3.75:1.0, and further subject to, upon the occurrence of a qualified acquisition in any quarter on or after the fifth fiscal quarter ending after the Leverage Ratio Step-Down, if so elected by the Company, a step-up to 4.25:1.0 for the four fiscal quarters following such qualified acquisition. The Company was in compliance with these covenants as of December 31, 2021. Convertible Senior Notes During 2014, the Company completed a private placement of approximately $1.44 billion principal amount of 0.500% Convertible Notes due 2019. All Convertible Notes were converted by their beneficial owners prior to their maturity on April 15, 2019. In accordance with the terms of the indenture governing the Convertible Notes, on April 15, 2019 the Company paid $1.16 billion in the outstanding aggregate principal amount of the Convertible Notes and delivered 4.9 million newly issued shares of its common stock in respect of the remainder of the Company's conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted, in full satisfaction of such converted notes. The Company received shares of its common stock under the Bond Hedges (as defined below) that offset the issuance of shares of common stock upon conversion of the Convertible Notes. During the year ended December 31, 2019, the Company recorded $1.6 million in contractual interest and $8.1 million in amortization of debt discount related to the Convertible Notes. Convertible Note Hedge and Warrant Transactions To minimize the impact of potential dilution upon conversion of the Convertible Notes, the Company entered into convertible note hedge transactions relating to approximately 16.0 million shares of common stock (the “Bond Hedges”) and also entered into separate warrant transactions (the “Warrant Transactions”) with each of the Option Counterparties relating to approximately 16.0 million shares of common stock to offset any payments in cash or shares of common stock at the Company’s election. As a result of the spin-off of its GoTo Business in January 2017, the number of shares of the Company's common stock covered by the Bond Hedges and Warrant Transactions was adjusted to approximately 20.0 million shares. As noted above, the Bond Hedges reduced the dilution upon conversion of the Convertible Notes, as the market price per share of common stock, as measured under the terms of the Bond Hedges, was greater than the strike price of the Bond Hedges, which initially corresponded to the conversion price of the Convertible Notes and was subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Convertible Notes. The Warrant Transactions would have separately had a dilutive effect to the extent that the market value per share of common stock, as measured under the terms of the Warrant Transactions, exceeded the applicable strike price of the warrants issued pursuant to the Warrant Transactions (the “Warrants”). The Warrants expired in ratable portions on a series of expiration dates that commenced on July 15, 2019 and concluded on November 18, 2019. During the year ended December 31, 2019, 14.9 million Warrants were exercised, and the Company delivered 1.0 million shares of its common stock as the volume weighted average stock price was above the Warrant strike price. Additionally, as of December 31, 2019, 5.4 million Warrants expired unexercised on various dates and no Warrants remain outstanding. The Warrants were not marked to market as the value of the Warrants were initially recorded in stockholders' equity and remained classified within stockholders' equity through their expiration. Bridge Facility and Take-Out Facility Commitment Letter On January 16, 2021, the Company entered into a bridge facility and take-out facility commitment letter (the “Commitment Letter”) pursuant to which JPMorgan Chase Bank, N.A. (1) committed to provide a senior unsecured 364-day term loan facility in an aggregate principal amount of $1.45 billion to finance the cash consideration for the Wrike acquisition in the event that the permanent debt financing was not available on or prior to the Closing Date and (2) agreed to use commercially reasonable efforts to assemble a syndicate of lenders to provide the necessary commitments for the senior term loan facility. The commitments under the Commitment Letter were permanently reduced to zero on February 18, 2021, as a result of (i) the effectiveness of the 2021 Term Loan Credit Agreement and (ii) the completion of the issuance of the 2026 Notes. In connection with the Commitment Letter, the Company incurred $5.4 million in issuance costs that were expensed in the first quarter of 2021 and are included in Interest expense in the accompanying consolidated statements of income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Derivatives Designated as Hedging Instruments As of December 31, 2021, the Company’s derivative assets and liabilities primarily resulted from cash flow hedges related to its forecasted operating expenses transacted in local currencies. A substantial portion of the Company’s overseas expenses are and will continue to be transacted in local currencies. To protect against fluctuations in operating expenses and the volatility of future cash flows caused by changes in currency exchange rates, the Company has established a program that uses foreign exchange forward contracts to hedge its exposure to these potential changes. The terms of these instruments, and the hedged transactions to which they relate, generally do not exceed 12 months. Generally, when the dollar is weak, foreign currency denominated expenses will be higher, and these higher expenses will be partially offset by the gains realized from the Company’s hedging contracts. Conversely, if the dollar is strong, foreign currency denominated expenses will be lower. These lower expenses will in turn be partially offset by the losses incurred from the Company’s hedging contracts. Derivative instruments are recognized as either assets or liabilities and are measured at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. Gains and losses on derivatives that are designated as cash flow hedges are initially reported as a component of Accumulated other comprehensive loss and are subsequently recognized in income when the hedged exposure is recognized in income. Gains and losses from changes in fair values of derivatives that are not designated as hedges are recognized in Other income, net. The total cumulative unrealized loss on cash flow derivative instruments was $0.6 million at December 31, 2021, and is included in Accumulated other comprehensive loss in the accompanying consolidated balance sheets. See Note 16 for more information related to comprehensive income. The net unrealized loss as of December 31, 2021 is expected to be recognized in income over the next 12 months at the same time the hedged items are recognized in income. Derivatives not Designated as Hedging Instruments A substantial portion of the Company’s overseas assets and liabilities are and will continue to be denominated in local currencies. To protect against fluctuations in earnings caused by changes in currency exchange rates when remeasuring the Company’s balance sheet, the Company utilizes foreign exchange forward contracts to hedge its exposure to this potential volatility. These contracts are not designated for hedge accounting treatment under the authoritative guidance. Accordingly, changes in the fair value of these contracts are recorded in Other income, net.

Earnings Per Share

Earnings Per Share	12 Months Ended

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share is calculated by dividing income available to stockholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted-average number of common and dilutive common share equivalents outstanding during the period. Dilutive common share equivalents consist of shares issuable upon the exercise or settlement of stock awards and shares issuable under the employee stock purchase plan (calculated using the treasury stock method) during the period they were outstanding and potential dilutive common shares from the conversion spread on the Convertible Notes and the warrants during the period they were outstanding. The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share information): Year Ended December 31, 2021 2020 2019 Numerator: Net income $ 307,499 $ 504,446 $ 681,813 Denominator: Denominator for basic earnings per share - weighted-average shares outstanding 124,113 123,575 130,853 Effect of dilutive employee stock awards 2,146 2,577 2,196 Effect of dilutive Convertible Notes — — 1,422 Effect of dilutive warrants — — 1,024 Denominator for diluted earnings per share - weighted-average shares outstanding 126,259 126,152 135,495 Basic earnings per share $ 2.48 $ 4.08 $ 5.21 Diluted earnings per share $ 2.44 $ 4.00 $ 5.03 For the years ended December 31, 2021 and 2020, there were no weighted-average number of shares outstanding used in the computation of diluted earnings per share for the warrants, as they expired on November 18, 2019. For the year ended December 31, 2019, the weighted-average number of shares outstanding used in the computation of diluted earnings per share includes the dilutive effect of the warrants, as the average stock price during the year was above the weighted-average warrant strike price of $94.42 per share. For the year ended December 31, 2021, anti-dilutive stock-based awards excluded from the calculations of diluted earnings per share were 1.8 million shares. For the years ended December 31, 2020 and 2019, stock-based awards excluded from the calculations of diluted earnings per share were not material. The Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on its Convertible Notes on diluted earnings per share because upon conversion the Company paid cash up to the aggregate principal amount of the Convertible Notes converted and delivered shares of common stock in respect of the remainder of the Company’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes converted. The conversion spread had a dilutive impact on diluted earnings per share when the average market price of the Company’s common stock for a given period exceeded the conversion price. For the years ended December 31, 2021 and 2020, there was no dilution as the Convertible Notes matured on April 15, 2019. For the year ended December 31, 2019, the average market price of the Company's common stock exceeded the conversion price; therefore, the dilutive effect of the Convertible Notes was included in the denominator of diluted earnings per share.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING 2021 Restructuring Program On November 15, 2021, the Company announced the implementation of a restructuring program (the “2021 Restructuring Program”) intended to improve operational efficiency. The 2021 Restructuring Program includes, among other things, the elimination of full-time positions, termination of certain contracts, and asset impairments, primarily related to facilities consolidations. The Company currently expects to record in the aggregate approximately $130.0 million to $240.0 million in pre-tax restructuring and asset impairment charges associated with the 2021 Restructuring Program. Included in these pre-tax charges are approximately $65.0 million to $90.0 million related to employee severance arrangements, approximately $40.0 million to $75.0 million related to the impairment of ROU and other assets from the consolidation of facilities, approximately $20.0 million to $35.0 million in contract termination costs and approximately $5.0 million to $40.0 million related to the impairment of certain acquired intangible assets. See Note 2 for detailed information on long-lived assets and intangible assets. The program is expected to be substantially completed over an estimated eighteen-month period. Other Restructuring Programs The Company has implemented other restructuring plans to reduce its cost structure, align resources with its product strategy and improve efficiency, which have resulted in workforce reductions and the consolidation of certain leased facilities. All of the activities related to these other restructuring plans are substantially complete. Restructuring Charges For the years ended December 31, 2021, 2020 and 2019, restructuring charges were comprised of the following (in thousands): Year Ended December 31, 2021 2020 2019 2021 Restructuring Program Employee severance and related costs $ 66,995 $ — $ — ROU asset impairment 20,927 — — Other asset impairment 15,401 — — Total 2021 Restructuring Program charges $ 103,323 $ — $ — Other Restructuring Programs Employee severance and related costs $ — $ 3,100 $ 19,581 Consolidation of leased facilities — — 2,666 ROU asset impairment — 8,881 — Total Other Restructuring Programs charges $ — $ 11,981 $ 22,247 Total Restructuring charges $ 103,323 $ 11,981 $ 22,247 The Company reviews for impairment of its long-lived assets, including ROU assets, whenever events or changes in circumstances indicate that the carrying amount of such assets may be impaired. Measurement of an impairment loss is based on the fair value of the asset compared to its carrying value. The fair value of the ROU assets is determined by utilizing the present value of the estimated future cash flows attributable to the assets. During the year ended December 31, 2021, in connection with the 2021 Restructuring Program the Company re-evaluated its real estate needs, resulting in a reduction of owned space and leased space, and the impairment of the associated ROU assets and property and equipment. For the year ended December 31, 2021, these actions resulted in a restructuring charge of $29.4 million, comprised of noncash charges of $20.9 million related to the impairment of operating lease ROU assets, and property and equipment of $8.5 million. Due to the actions taken above, the Company tested the operating lease ROU assets and certain property and equipment for recoverability by comparing the carrying value of the asset group to an estimate of the future undiscounted cash flows expected to result from the use and eventual disposition of the asset group. Based on the results of the recoverability test, the Company determined that the undiscounted cash flows of the asset groups were below the carrying values, indicating impairment. The Company then determined the fair value of the asset groups by utilizing the present value of the estimated future cash flows attributable to the assets. In addition, during the year ended December 31, 2021, in connection with the 2021 Restructuring Program, the Company determined that certain capitalized internal use software did not have ongoing economic benefits and recorded impairment charges of $6.2 million. During the year ended December 31, 2020, in connection with the COVID-19 pandemic, the Company determined that a vacant facility partially impaired under a previous restructuring plan became fully impaired due to a reassessment of the timing and fees of the assumed sublease rentals and recorded impairment charges of $8.9 million. These non-recurring fair value measurements were categorized as Level 3, as significant unobservable inputs were utilized. Restructuring accruals The activity in the Company’s restructuring accruals for the year ended December 31, 2021 is summarized as follows (in thousands): 2021 Restructuring Program Balance at January 1, 2021 $ — Employee severance and related costs 66,995 Payments (38,893) Balance at December 31, 2021 $ 28,102

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Legal Matters On January 22, 2022, a putative shareholder derivative complaint was filed in the United States District Court for the Southern District of Florida, naming the Company as a nominal defendant and certain of its current and former officers and directors as defendants. The complaint asserts claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and violations of Sections 10(b), 14(a), 20(a), and 21D of the Securities Exchange Act of 1934, and Rule 10b-5, promulgated thereunder. The complaint, which references the securities class action filed November 19, 2021, alleges that the defendants made or caused the Company to make false or misleading statements that failed to disclose that the Company was struggling to transition customers from an on-premise offering to a cloud-based subscription offering and that the Company failed to maintain adequate internal controls. The complaint also alleges that the defendants caused the Company to repurchase shares at inflated stock prices. The complaint seeks an award of damages and restitution to the Company as a result of the alleged violations, plaintiff's costs and disbursements, including reasonable attorneys' and experts' fees, costs and other expenses, as well as corporate governance enhancements. The Company believes that it and the defendants have meritorious defenses to these allegations; however, the Company is unable to currently determine the ultimate outcome of this matter or the potential exposure or loss, if any. Agreement and Plan of Merger On January 31, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), with Picard Parent, Inc. (“Parent”), Picard Merger Sub, Inc., a wholly owned subsidiary of Parent (“Merger Sub”) and, for certain limited purposes detailed in the Merger Agreement, TIBCO Software, Inc. (“TIBCO”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Parent. Parent and Merger Sub were formed by TIBCO, an indirect subsidiary of an affiliate of Vista Equity Partners (“Vista”). Vista is partnering with Evergreen Coast Capital Corp., an affiliate of Elliott Investment Management L.P., to acquire all of the Company’s outstanding shares of common stock (the “Company Common Stock”) for $104.00 per share in cash. The Merger is conditioned upon, among other things, the approval of the Merger Agreement by the affirmative vote of holders of at least a majority of all outstanding shares of Company Common Stock at a meeting of the Company’s stockholders held for such purpose, the expiration of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, certain other approvals, clearances or expirations of waiting periods under other antitrust laws and foreign investment screening laws, and other customary closing conditions. Subject to the satisfaction (or if applicable, waiver) of such conditions, the Merger is expected to close mid-year 2022.

Accounting Policies [Abstract]
Consolidation Policy	Consolidation PolicyThe consolidated financial statements of the Company include the accounts of its wholly-owned subsidiaries in the Americas; Europe, the Middle East and Africa (“EMEA”); and Asia-Pacific and Japan (“APJ”). All significant transactions and balances between the Company and its subsidiaries have been eliminated in consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Business Combinations In October 2021, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update on business combinations. The new guidance requires companies to apply revenue guidance under Accounting Standards Codification Topic 606 to recognize and measure contract assets and contract liabilities acquired in a business combination on the acquisition date. This approach differs from the current requirement to measure contract assets and contract liabilities acquired in a business combination at fair value. The update will be effective for the Company beginning in the first quarter of 2023, though early adoption is permitted. The Company is currently evaluating the timing of adoption and impact of this new standard. Income Taxes In December 2019, the FASB issued an accounting standard update on income taxes. The new guidance eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The Company adopted this standard effective January 1, 2021. The adoption of this standard did not have a material impact on the Company's consolidated financial position, results of operations and cash flows. Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the FASB issued an accounting standard update to guidance applicable to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are effective for all entities as of March 12, 2020, through December 31, 2022. The Company is currently evaluating the impact, but does not expect the standard to have a material impact on its consolidated financial position, results of operations and cash flows.
Reclassifications	ReclassificationsCertain reclassifications of the prior years' amounts have been made to conform to the current year's presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates made by management include estimation for reserves for legal contingencies, the standalone selling price of certain performance obligations related to revenue recognition, the provision for credit losses related to accounts receivable, contract assets, and available-for-sale debt securities, the provision to reduce obsolete or excess inventory to net realizable value, the provision for estimated returns, as well as sales allowances, the assumptions used in the valuation of stock-based awards and measurement of expense related to performance stock units, the assumptions used in the discounted cash flows to mark certain of its investments to market, the valuation of the Company’s goodwill, valuation of acquired intangible assets and liabilities, net realizable value of product related and other intangible assets, the provision for income taxes, valuation allowance for deferred tax assets, uncertain tax positions, and the amortization and depreciation periods for contract acquisition costs, intangible and long-lived assets. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole, the actual amounts of such items, when known, will vary from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents at December 31, 2021 and 2020 include marketable securities, which are primarily money market funds, corporate securities and government securities with initial or remaining contractual maturities when purchased of three months or less.
Available-for-sale Investments	Available-for-sale Investments Short-term and long-term available for sale investments in debt securities at December 31, 2021 and 2020 primarily consist of agency securities, corporate securities and government securities. Investments classified as available-for-sale debt securities are stated at fair value with unrealized gains and losses, net of taxes, reported in Accumulated other comprehensive loss in the accompanying consolidated balance sheets. The Company classifies its available-for-sale investments as current and non-current based on their actual remaining time to maturity. The Company does not recognize unrealized changes in the fair value of its available-for-sale debt securities in income unless a security is deemed to be impaired. The allowance for credit losses on the Company's investments in available-for-sale debt securities is determined using a quantitative discounted cash flow analysis if impairment triggers exist after a qualitative screen is completed. Impairment on available-for-sale debt securities is determined on an individual security basis and the security is subject to impairment when its fair value declines below its amortized cost basis. If the fair value is less than the amortized cost basis, management must then determine whether it intends to sell the security or whether it is more likely than not that it will be required to sell the security before it recovers its value. If management intends to sell the security or will more-likely-than-not be required to sell the impaired security before it recovers its value, a credit loss is recorded to Other income, net in the accompanying consolidated statements of inc ome. If management does not intend to sell the security, nor will it more-likely-than-not be required to sell the security before the security recovers its value, management must then determine whether the loss is due to credit loss or other factors. For impairment indicators due to credit loss factors, management establishes an allowance for credit losses with a charge to Other income, net. F or impairment indicators due to other factors, management records the loss with a charge to Accumulated other comprehensive loss
Fair value measurements	Fair Value Measurements The authoritative guidance defines fair value as an exit price, representing the amount that would either be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: • Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2 . Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and • Level 3 . Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Available-for-sale securities included in Level 2 are valued utilizing inputs obtained from an independent pricing service (the “Service”) which uses quoted market prices for identical or comparable instruments rather than direct observations of quoted prices in active markets. The Service applies a four level hierarchical pricing methodology to all of the Company’s fixed income securities based on the circumstances. The hierarchy starts with the highest priority pricing source, then subsequently uses inputs obtained from other third-party sources and large custodial institutions. The Service’s providers utilize a variety of inputs to determine their quoted prices. These inputs may include interest rates, known historical trades, yield curve information, benchmark data, prepayment speeds, credit quality and broker/dealer quotes. Substantially all of the Company’s available-for-sale investments are valued utilizing inputs obtained from the Service and accordingly are categorized as Level 2. The Company periodically independently assesses the pricing obtained from the Service and historically has not adjusted the Service's pricing as a result of this assessment. Available-for-sale securities are included in Level 3 when relevant observable inputs for a security are not available. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of assets and liabilities within the fair value hierarchy. In certain instances, the inputs used to measure fair value may meet the definition of more than one level of the fair value hierarchy. The input with the lowest level priority is used to determine the applicable level in the fair value hierarchy. See Note 5 for additional information regarding the Company’s fair value measurements.
Inventory	InventoryInventories are stated at the lower of cost or net realizable value on a standard cost basis, which approximates actual cost.
Contract Acquisition Costs and Revenue	Contract acquisition costs The Company is required to capitalize certain contract acquisition costs, consisting primarily of commissions paid and related payroll taxes when contracts are signed. The asset recognized from capitalized incremental and recoverable acquisition costs is amortized over the expected period of benefit on a basis consistent with the pattern of transfer of the products or services to which the asset relates. The Company elects to apply a practical expedient to expense contract acquisition costs as incurred where the pattern of transfer is one year or less. The Company’s typical contracts include performance obligations related to subscription, product and licenses, and support and services. Contract acquisition costs are allocated to performance obligations using a portfolio approach. The Company assesses its sales compensation plans at least annually to evaluate whether contract acquisition costs for renewals and extensions are commensurate with those related to initial contracts. If concluded to be commensurate, the contract acquisition costs are amortized over the contractual term on a basis consistent with the pattern of transfer of the products or services to which the asset relates. If concluded not to be commensurate, the contract acquisition costs are amortized over the greater of the contractual term or estimated customer life on a basis consistent with the pattern of transfer of the products or services to which the asset relates. The Company estimates an average customer life of three years to five years, which it believes is appropriate based on consideration of the historical average customer life and the estimated useful life of the underlying product and license sold as part of the transaction. Revenue Significant Judgments The Company generates all of its revenues from contracts with customers. At contract inception, the Company assesses the solutions or services, or bundles of solutions and services, obligated in the contract with a customer to identify each performance obligation within the contract, and then evaluates whether the performance obligations are capable of being distinct and distinct within the context of the contract. Solutions and services that are not both capable of being distinct and distinct within the context of the contract are combined and treated as a single performance obligation in determining the allocation and recognition of revenue. The standalone selling price is the price at which the Company would sell a promised product or service separately to the customer. For the majority of the Company's software licenses and hardware, CSP and on-premise subscription software licenses, the Company uses the observable price in transactions with multiple performance obligations. For the majority of the Company’s support and services, and cloud-hosted subscription offerings, the Company uses the observable price when the Company sells that support and service and cloud-hosted subscription separately to similar customers. If the standalone selling price for a performance obligation is not directly observable, the Company estimates it. The Company estimates the standalone selling price by taking into consideration market conditions, economics of the offering and customers’ behavior. The Company maximizes the use of observable inputs and applies estimation methods consistently in similar circumstances. The Company allocates the transaction price to each distinct performance obligation on a relative standalone selling price basis. Product Concentration The Company derives a substantial portion of its revenues from its Workspace solutions, which include its Citrix Virtual Apps and Desktops solutions and related services, and anticipates that these solutions and future derivative solutions and product lines based upon this technology will continue to constitute a majority of its revenue. The Company could experience declines in demand for its Workspace solutions and other solutions, whether as a result of general economic conditions, the delay or reduction in technology purchases, new competitive product releases, price competition, and lack of success of its strategic partners, technological change or other factors. Additionally, the Company's App Delivery and Security products generate revenues from a limited number of customers. As a result, if the App Delivery and Security product grouping loses certain customers or one or more such customers significantly decreases its orders, the Company's business, results of operations and financial condition could be adversely affected. Cost of Net Revenues Cost of subscription, support and services revenues consists primarily of compensation and other personnel-related costs of providing technical support, consulting and cloud capacity costs, as well as the costs related to providing the Company's offerings delivered via the cloud and hardware costs related to certain on-premise subscriptions offerings. Cost of product and license revenues consists primarily of hardware, royalties, product media and duplication, manuals, shipping expense, and packaging materials. In addition, the Company is a party to licensing agreements with various entities, which give the Company the right to use certain software code in its solutions or in the development of future solutions in exchange for the payment of fixed fees or amounts based upon the sales of the related product. Costs related to these agreements are included in Cost of net revenues. Also included in Cost of net revenues is amortization and impairment of product related intangible assets.
Derivatives and Hedging Activities	Derivatives and Hedging Activities In accordance with the authoritative guidance, the Company records derivatives at fair value as either assets or liabilities on the balance sheet. For derivatives that are designated as and qualify as cash flow hedges, the unrealized gain or loss on the derivative instrument is reported as a component of Accumulated other comprehensive loss and reclassified into earnings as operating expense, net, when the hedged transaction affects earnings. Derivatives not designated as hedging instruments are adjusted to fair value through earnings as Other income, net, in the period during which changes in fair value occur. The application of the authoritative guidance could impact the volatility of earnings. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes attributing all derivatives that are designated as cash flow hedges of forecasted transactions. The Company also formally assesses, both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in cash flows of the hedged item. Fluctuations in the value of the derivative instruments are generally offset by changes in the hedged item; however, if it is determined that a derivative is not highly effective as a hedge or if a derivative ceases to be a highly effective hedge, the Company will discontinue hedge accounting prospectively for the affected derivative. The Company is exposed to risk of default by its hedging counterparties. Although this risk is concentrated among a limited number of counterparties, the Company’s foreign exchange hedging policy attempts to minimize this risk by placing limits on the amount of exposure that may exist with any single financial institution at a time.
Property and Equipment	Property and Equipment Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is generally three years for computer equipment; the lesser of the lease term or ten years for leasehold improvements, which is the estimated useful life; seven years for office equipment and furniture and the Company’s enterprise resource planning systems; and forty years for buildings.
Long-Lived Assets	Long-Lived AssetsThe Company reviews for impairment of long-lived assets and certain identifiable intangible assets to be held and used whenever events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss is based on the fair value of the asset compared to its carrying value. Long-lived assets and certain identifiable intangible assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Goodwill	GoodwillThe Company accounts for goodwill in accordance with the authoritative guidance, which requires that goodwill and certain intangible assets are not amortized, but are subject to an annual impairment test. There was no impairment of goodwill or indefinite lived intangible assets as a result of the annual impairment analysis completed during the fourth quarters of 2021 and 2020.
Intangible Assets	Intangible AssetsThe Company has intangible assets which were primarily acquired in conjunction with business combinations and technology purchases. Intangible assets with finite lives are recorded at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets, generally two seven
Software Development Costs	Software Development Costs The authoritative guidance requires certain internal software development costs related to software to be sold to be capitalized upon the establishment of technological feasibility. The Company's software development costs incurred subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.
Internal Use Software	Internal Use SoftwareIn accordance with the authoritative guidance, the Company capitalizes external direct costs of materials and services and internal costs such as payroll and benefits of those employees directly associated with the development of new functionality in internal use software.
Pension Liability	Pension Liability The Company provides retirement benefits to certain employees who are not U.S. based. Generally, benefits under these programs are based on an employee’s length of service and level of compensation. The majority of these programs are commonly referred to as termination indemnities, which provide retirement benefits in accordance with programs mandated by the governments of the countries in which such employees work.
Foreign Currency	Foreign CurrencyThe functional currency for all of the Company’s wholly-owned foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities of such subsidiaries are remeasured into U.S. dollars at exchange rates in effect at the balance sheet date, and revenues and expenses are remeasured at average rates prevailing during the year. Foreign currency transaction gains and losses are the result of exchange rate changes on transactions denominated in currencies other than the functional currency. The remeasurement of those foreign currency transactions is included in determining net income or loss for the period of exchange.
Advertising Costs	Advertising CostsThe Company expenses advertising costs as incurred. The Company has advertising agreements with, and purchases advertising from, online media providers to advertise its solutions. The Company also has strategic development funds and cooperative advertising agreements with certain distributors and resellers whereby the Company will reimburse distributors and resellers for qualified advertising of Company solutions. Reimbursement is made once the distributor, reseller or provider provides substantiation of qualified expenses. The Company estimates the impact of these expenses and recognizes them at the time of product sales as a reduction of net revenue in the accompanying consolidated statements of income.
Income Taxes	Income Taxes In the ordinary course of global business, there are transactions for which the ultimate tax outcome is uncertain; thus, judgment is required in determining the worldwide provision for income taxes. The Company provides for income taxes on transactions based on its estimate of the probable liability. The Company adjusts its provision as appropriate for changes that impact its underlying judgments. Changes that impact provision estimates include such items as jurisdictional interpretations on tax filing positions based on the results of tax audits and general tax authority rulings. The Company provides for global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries in the year the tax is incurred. Due to the evolving nature of tax rules combined with the large number of jurisdictions in which the Company operates, estimates of its tax liability and the realizability of its deferred tax assets could change in the future, which may result in additional tax liabilities and adversely affect the Company’s results of operations, financial condition and cash flows.
Accounting for Stock-Based Compensation Plans	Accounting for Stock-Based Compensation PlansThe Company has various stock-based compensation plans for its employees and outside directors and accounts for stock-based compensation arrangements in accordance with the authoritative guidance, which requires the Company to measure and record compensation expense in its consolidated financial statements using a fair value method. The Company accounts for forfeitures as they occur.
Earnings Per Share	Earnings per ShareBasic earnings per share is calculated by dividing income available to stockholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted-average number of common and dilutive common share equivalents outstanding during the period. Dilutive common share equivalents consist of shares issuable upon the exercise or settlement of stock awards and shares issuable under the employee stock purchase plan (calculated using the treasury stock method) during the period they were outstanding and potential dilutive common shares from the conversion spread on the Company’s 0.500% Convertible Notes due 2019 (the “Convertible Notes”) and the Company's warrants during the period they were outstanding.
Leases	Leases The Company leases certain office space and equipment under various leases. In addition to rent, the leases require the Company to pay for taxes, insurance, maintenance and other operating expenses. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, accrued expenses and other current liabilities, and operating lease liabilities in the Company’s consolidated balance sheets. Finance leases are included in property and equipment, net, accrued expenses and other current liabilities and other long-term liabilities in the Company’s consolidated balance sheets. Finance leases were not material to the consolidated balance sheets as of December 31, 2021 and 2020, respectively. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are
