Organization, Consolidation and Presentation of Financial Statements [Abstract]
Company	Company Red Hat, Inc., incorporated in Delaware, together with its subsidiaries (“Red Hat” or the “Company”) is a leading global provider of open source software solutions, using a community-powered approach to develop and offer reliable and high-performing operating system, virtualization, management, middleware, cloud, mobile and storage technologies. Open source software is an alternative to proprietary software and represents a different model for the development and licensing of commercial software code than that typically used for proprietary software. Because open source software code is often freely shared, there are customarily no licensing fees for the use of open source software. Therefore, the Company does not recognize revenue from the licensing of the code itself. The Company provides value to its customers through the development, aggregation, integration, testing, certification, delivery, maintenance, enhancement and support of its Red Hat technologies, and by providing a level of performance, scalability, flexibility, reliability and security for the technologies the Company packages and distributes. Moreover, because communities of developers not employed by the Company assist with the creation of the Company’s open source offerings, opportunities for further innovation of the Company’s offerings are supplemented by these communities. The Company derives its revenue and generates cash from customers primarily from two sources: (i) subscription revenue and (ii) training and services revenue. These arrangements typically involve subscriptions to Red Hat technologies. The arrangements with the Company’s customers that produce this revenue and cash are explained in further detail in NOTE 2 —Summary of Significant Accounting Policies.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation The accompanying Consolidated Financial Statements include the accounts of the Company and all of its wholly owned subsidiaries. All significant inter-company accounts and transactions are eliminated in consolidation. There are no significant foreign exchange restrictions on the Company’s foreign subsidiaries. The Consolidated Statement of Cash Flows for the year ended February 29, 2016 includes the effect of retrospective application of Accounting Standards Update 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). Under ASU 2016-09, all windfall tax benefits related to share-based payments are reported as cash flows from operating activities along with all other income tax cash flows. Previously, windfall tax benefits from share-based payment arrangements were reported as cash flows from financing activities. With the Company’s permitted election to retrospectively apply this classification amendment, $20.2 million of windfall tax benefits previously reported as cash inflows from financing activities on the Company’s Consolidated Statement of Cash Flows for the fiscal year ended February 29, 2016 have been reclassified as cash inflows from operating activities. Prior to adopting ASU 2016-09, the Company credited windfall tax benefits related to share-based compensation to Additional paid-in capital in the Company’s Consolidated Balance Sheets. Under ASU 2016-09, these windfalls are recognized as a discrete tax benefit in the Company’s Consolidated Statements of Operations. ASU 2016-09 requires companies to adopt the amendment relating to accounting for windfalls and shortfalls on a prospective basis only. As a result, no change has been made to the Consolidated Statements of Operations for the fiscal year ended February 29, 2016 related to the $19.8 million of net windfall tax benefits the Company recognized as additional paid-in capital during the fiscal year ended February 29, 2016. For additional discussion related to recent accounting pronouncements the Company has either recently adopted or is currently evaluating the impact from future adoption, see “Recent accounting pronouncements” in this note. In addition to the reclassifications resulting from application of ASU 2016-09, certain other amounts for the fiscal years ended February 28, 2017 and February 29, 2016 have been reclassified to conform to the current year presentation. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from such estimates. Estimates are used for, but not limited to, revenue recognition, goodwill and other long-lived assets, share-based compensation, income taxes and loss contingencies. Revenue recognition The Company establishes persuasive evidence of a sales arrangement for each type of revenue transaction based on either a signed contract with the end customer, a click-through contract on the Company’s website whereby the customer agrees to the Company’s standard subscription terms, signed or click-through distribution contracts with original equipment manufacturers (“OEMs”) and other resellers, or, in the case of individual training seats, through receipt of payment that indicates acceptance of the Company’s training agreement terms. Subscription revenue Subscription revenue is comprised of direct and indirect sales of subscriptions relating to Red Hat technologies. Accounts receivable and deferred revenue are recorded at the time a customer enters into a binding subscription agreement for the purchase of a subscription, subscription services are made available to the customer and the customer is billed. The deferred revenue amount is recognized as revenue ratably over the subscription period. Red Hat technologies are generally offered with either one - or three -year base subscription periods; the majority of the Company’s subscriptions have one-year terms. Under these subscription agreements, renewal rates are generally specified for one or three -year renewal terms. Subscriptions generally entitle the end user to the technology itself and post-contract customer support, generally consisting of varying levels of support services as well as access to security updates, fixes, functionality enhancements, upgrades to the technologies, each on an if and when available basis, and compatibility with an ecosystem of certified hardware and software, during the term of the subscription. The Company sells its offerings through two principal channels: (1) direct, which includes sales by the Company’s sales force as well as web store sales, and (2) indirect, which includes certified cloud and service providers (“CCSPs”), distributors, OEMs, systems integrators and value added resellers. The Company recognizes revenue from the sale of Red Hat technologies ratably over the period of the subscription beginning on the commencement date of the subscription agreement. Subscription arrangements with large enterprise customers often have contracts with multiple elements (e.g., software technology, support, training, consulting and other services). The Company allocates revenue to each element of the arrangement based on vendor-specific objective evidence (“VSOE”) of each element’s fair value when the Company can demonstrate sufficient evidence of the fair value of at least those elements that are undelivered. The fair value of each element in multiple element arrangements is created by either (i) providing the customer with the ability during the term of the arrangement to renew that element at the same rate paid for the element included in the initial term of the agreement or (ii) selling the element on a stand-alone basis. The Company derives a portion of its revenue from CCSPs that provide public clouds with, and allow users to consume, computing resources as a service. The Company earns revenue based on subscription units consumed by the CCSP or its end users. The Company uses its historical cloud-usage data to estimate the amount of revenue earned and recognized each month and adjusts to actual amounts earned upon receipt of usage reports from the CCSPs in the following month. Training and services revenue Training and services revenue is comprised of revenue for consulting, engineering and customer training and education services. Consulting services consist of time-based arrangements, and revenue is recognized as these services are performed. Engineering services represent revenue earned under fixed fee arrangements with the Company’s OEM partners and other customers to provide for significant modification and customization of Red Hat technologies. The Company recognizes revenue for these fixed fee engineering services using the percentage of completion basis of accounting, provided the Company has the ability to make reliable estimates of progress towards completion, the fee for such services is fixed or determinable and collection of the resulting receivable is probable. Under the percentage of completion method, earnings under the contract are recognized based on the progress toward completion as estimated using the ratio of labor hours incurred to total expected project hours. Changes in estimates are recognized in the period in which they are known. Revenue for customer training and education services is recognized on the dates the services are complete. Deferred selling costs Deferred commissions are the incremental costs that are directly associated with non-cancellable subscription contracts with customers and consist of sales commissions paid to the Company’s sales force. The commissions are deferred and amortized over a period that approximates the subscription period. The commission payments are paid in full subsequent to the month in which the customer’s service commences. The deferred commission amounts are recoverable through the future revenue streams under the non-cancellable customer contracts. In addition, the Company has the ability and intent under the commission plans with its sales force to recover commissions previously paid to its sales force in the event that customers breach the terms of their subscription agreements and do not fully pay for their subscription agreements. Deferred commissions are included in Prepaid expenses and Other assets, net on the accompanying Consolidated Balance Sheets. Amortization of deferred commissions is included in sales and marketing expense in the accompanying Consolidated Statements of Operations. Goodwill and other long-lived assets Goodwill The Company evaluates goodwill for impairment during the fourth quarter of its fiscal year or more frequently if events or changes in circumstances indicate that an impairment to goodwill may have occurred. For fiscal years ended February 28, 2018 and February 28, 2017, the Company applied its test for goodwill impairment as permitted by Accounting Standards Update 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment (“ASU 2011-08”), which allows the Company to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying value. The outcome of these qualitative tests determines whether it is necessary to proceed with a quantitative impairment assessment. After considering such qualitative factors as macroeconomic conditions, actual or anticipated changes to cost factors (for example, selling and delivery), overall financial performance and other Company-specific factors, such as potential changes in strategy, the Company determined that it was not more likely than not that any impairment to goodwill had occurred during the fiscal years ended February 28, 2018 and February 28, 2017. For the fiscal year ended February 29, 2016, the Company elected to perform a quantitative assessment of goodwill for all of its reporting units. In doing so, the Company compared the estimated fair value of each of the reporting units to its respective book value, including allocated goodwill. The Company concluded that there were no impairments of goodwill. Other long-lived assets The Company evaluates the recoverability of its property and equipment and other long-lived assets whenever events or changes in circumstances indicate that an impairment may have occurred. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or the business to which the assets relate. Impairment losses, if any, are measured as the amount by which the carrying value exceeds the fair value of the assets. Cash, cash equivalents and restricted cash The Company considers highly liquid investments purchased with a maturity period of three months or less at the date of purchase to be cash equivalents. The Company’s restricted cash totaled $4.2 million and $3.1 million at February 28, 2018 and February 28, 2017 , respectively, and includes cash restricted as part of collateral for certain office facilities. Restricted cash is included with Cash, cash equivalents and restricted cash on the Company’s Consolidated Balance Sheets. Accounts receivable and allowance for doubtful accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on historical write-off experience. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when the Company determines it is probable the receivable will not be recovered. The Company does not have off-balance sheet credit exposure related to its customers. See NOTE 3 —Accounts Receivable for further discussion on accounts receivable balances. Fair value measurements Fair value is defined as the exchange price that would be received for the purchase of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for such asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value should maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. The Company’s investments are comprised primarily of debt securities that are classified as available for sale and recorded at their fair values. Liquid investments with effective maturities of three months or less at the date of purchase are classified as cash equivalents. Investments with remaining effective maturities of twelve months or less from the balance sheet date are classified as short-term investments. Investments with remaining effective maturities of more than twelve months from the balance sheet date are classified as long-term investments. The Company’s Level 1 financial instruments are valued using quoted prices in active markets for identical instruments. The Company’s Level 2 financial instruments, including derivative instruments, are valued using quoted prices for identical instruments in less active markets or using other observable market inputs for comparable instruments. Unrealized gains and temporary losses on investments classified as available for sale are included within accumulated other comprehensive income, net of any related tax effect. Realized gains and losses are recorded using the specific identification method and upon realization, such amounts are reclassified from accumulated other comprehensive income to Other income (expense), net. Realized gains and losses and other than temporary impairments, if any, are reflected in the Company’s Consolidated Statements of Operations as Other income (expense), net. The Company does not recognize changes in the fair value of its investments in income unless a decline in value is considered other than temporary. The vast majority of the Company’s investments are priced by pricing vendors. These pricing vendors use the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs. In the event observable inputs are not available, the Company assesses other factors to determine the security’s market value, including broker quotes or model valuations. Independent price verifications of all holdings are performed by pricing vendors that are then reviewed by the Company. In the event a price fails a pre-established tolerance check, it is researched so that the Company can assess the cause of the variance to determine what the Company believes is the appropriate fair value. See NOTE 19 —Assets and Liabilities Measured at Fair Value on a Recurring Basis for further discussion on fair value measurements. The Company minimizes its credit risk associated with investments by investing primarily in investment grade, liquid securities. The Company’s policy is designed to limit exposures to any one issuer depending on credit quality. Periodic evaluations of the relative credit standing of those issuers are considered in the Company’s investment strategy. Internal use software The Company capitalizes costs related to the development of internal use software for its website, enterprise resource planning system and systems management applications. The Company amortizes the costs of computer software developed for internal use on a straight-line basis over an estimated useful life of five years. The carrying value of internal use software is included in property and equipment on the Company’s Consolidated Balance Sheets. Capitalized software costs Capitalization of software development costs for products to be sold to third parties begins upon the establishment of technological feasibility and ceases when the product is available for general release. As a result of the Company’s practice of frequently releasing source code that it has developed on an on-going basis for unrestricted download on the Internet, there is generally no passage of time between achievement of technological feasibility and the availability of the Company’s product for general release. Therefore, at February 28, 2018 and February 28, 2017 , the Company had no internally developed capitalized software costs for products to be sold to third parties. Property and equipment Property and equipment is primarily comprised of furniture, computer and other equipment, computer software and leasehold improvements, which are recorded at cost and depreciated or amortized using the straight-line method. Expenditures for maintenance and repairs are charged to operations as incurred; major expenditures for renewals and betterments are capitalized and depreciated. Property and equipment acquired under capital leases are depreciated over the lesser of the estimated remaining useful life of the asset or the remaining term of the lease. Share-based compensation The Company measures share-based compensation cost as of the grant date, based on the estimated fair value of the award and recognizes the cost over the employee requisite service period typically on a straight-line basis. The Company estimates the fair value of stock options using the Black-Scholes-Merton valuation model. The fair value of nonvested share awards, nonvested share units and performance share units (“PSUs”) are measured at their underlying closing share price on the date of grant. The Company’s share-based compensation is described further in NOTE 17 —Share-based Awards. Sales and marketing expenses Sales and marketing expenses consist of costs, including salaries, sales commissions and related expenses, such as travel, of all personnel involved in the sales and marketing process. Sales and marketing expenses also include costs of advertising, sales lead generation programs, cooperative marketing arrangements and trade shows. Payments made to resellers or other customers are recognized as a reduction of revenue unless the Company (i) receives an identifiable benefit (goods or services) in exchange for such payments that is sufficiently separable from the purchase of the Company’s products and (ii) the Company can reasonably estimate the fair value of the benefit identified. Advertising costs are expensed as incurred. Advertising expense totaled $111.5 million , $95.7 million and $88.9 million for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 , respectively. Research and development expenses Research and development expenses include all direct costs, primarily salaries for Company personnel and outside consultants, related to the development of new software products, significant enhancements to existing software products, and the portion of costs of development of internal use software required to be expensed. Research and development costs are charged to operations as incurred. Income taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company continues to assess the realizability of its deferred tax assets, which primarily consist of share-based compensation expense deductions, tax credit carryforwards and deferred revenue. In assessing the realizability of these deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The Company continues to maintain a valuation allowance against its deferred tax assets with respect to certain foreign net operating loss (“NOL”) carryforwards. With respect to foreign earnings, it has been the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law. This new law includes a provision that imposes a transition tax on foreign earnings whether or not such earnings are repatriated to the U.S. In light of this new tax, the Company is reviewing its prior position on the reinvestment of the earnings of foreign subsidiaries outside of the U.S. Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, the Company makes certain estimates and assumptions in (i) calculating its income tax expense, deferred tax assets and deferred tax liabilities, (ii) determining any valuation allowance recorded against deferred tax assets and (iii) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. The Company’s estimates and assumptions may differ significantly from tax benefits ultimately realized. The Company’s income tax expense and deferred taxes are described further in NOTE 10 —Income Taxes. Foreign currency translation The Euro has been determined to be the primary functional currency for the Company’s European operations, and local currencies have been determined to be the functional currencies for the Company’s Asia Pacific and Latin American operations. Foreign exchange gains and losses, which result from the process of remeasuring foreign currency transactions into the appropriate functional currency, are included in Other income (expense), net in the Company’s Consolidated Statements of Operations. The impact of changes in foreign currency exchange rates resulting from the translation of foreign currency financial statements into U.S. dollars for financial reporting purposes is included in other comprehensive income, which is a separate component of stockholders’ equity. Assets and liabilities are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at average rates for the period. Customers and credit risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, investments and trade receivables. The Company primarily places its cash, cash equivalents and investments with high-credit quality financial institutions that invest predominantly in U.S. government instruments, investment grade corporate bonds and certificates of deposit guaranteed by banks that are members of the Federal Deposit Insurance Corporation. Cash deposits are primarily in financial institutions in the U.S. and the United Kingdom. However, cash for monthly operating costs of international operations are deposited in banks outside the U.S. The Company performs credit evaluations to reduce credit risk and generally requires no collateral from its customers. Management estimates the allowance for uncollectible accounts based on its historical experience and credit evaluation. The Company’s standard credit terms are net 30 days in North America, net 30 to net 45 days in EMEA (Europe, Middle East and Africa) and Latin America, and range from net 30 to net 60 days in Asia Pacific (principally Australia, China, India, Japan, Singapore and South Korea). Net income per common share The Company computes basic net income per common share by dividing net income available to common stockholders by the weighted average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. Potential common share equivalents consist of shares issuable upon the exercise of stock options or vesting of share-based awards. With respect to the Company’s 0.25% convertible senior notes due 2019 (the “convertible notes”), the Company has the option to pay cash or deliver, as the case may be, either cash, shares of its common stock or a combination of cash and shares of its common stock for the aggregate amount due upon conversion of the convertible notes. The Company’s intent is to settle the principal amount of the convertible notes in cash upon conversion. As a result, upon conversion of the convertible notes, only the amounts payable in excess of the principal amounts of the notes are considered in diluted earnings per share under the treasury stock method. See NOTE 11 —Convertible Notes for detailed information on the convertible notes. Segment reporting The Company is organized primarily on the basis of three geographic business units: the Americas (U.S., Canada and Latin America), EMEA and Asia Pacific. These business units are aggregated into one reportable segment due to the similarity in nature of products and services provided, financial performance economic characteristics (e.g., revenue growth and gross margin), methods of production and distribution and customer classes (e.g., cloud service providers, distributors, resellers and enterprise). The Company has offices in more than 95 locations around the world. The Company manages its international business on an Americas-wide, EMEA-wide and Asia Pacific-wide basis. See NOTE 20 —Segment Reporting for further discussion. Recent accounting pronouncements Accounting pronouncements adopted In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). The FASB issued ASU 2017-09 to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying the guidance in Topic 718, to a change to the terms and conditions of a share-based payment award. The Company early adopted ASU 2017-09 as of the second quarter of its fiscal year ended February 28, 2018. The adoption of this update did not impact the Company’s Consolidated Financial Statements. In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) . The FASB issued ASU 2017-04 to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under this updated standard, an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity also should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if any. The FASB also eliminated the requirement for reporting units with a zero or negative carrying amount to first perform a qualitative assessment. The Company adopted ASU 2017-04 during the second quarter of its fiscal year ended February 28, 2018. The adoption of this update did not impact the Company’s Consolidated Financial Statements. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The FASB issued ASU 2016-15 to decrease the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. The Company adopted ASU 2016-15 along with Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”) during the fourth quarter of its fiscal year ended February 28, 2018. The adoption of these updates did not significantly impact the Company’s Consolidated Financial Statements. Accounting pronouncements being evaluated In February 2018, the FASB issued Accounting Standards Update 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The FASB issued ASU 2018-02 to give entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the enactment of the Tax Act to retained earnings. The guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2020, with early adoption permitted. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842) (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations with respect to accounting for leases. Under ASU 2016-02, lessees will recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. This guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2020. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements. In January 2016, the FASB issued Accounting Standards Update 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The FASB issued ASU 2016-01 to require equity investments with readily determinable fair values to be measured at fair value with changes in fair value recognized in net income. Equity investments that do not have readily determinable fair values are allowed to be remeasured upon the occurrence of an observable price change or upon identification of an impairment. This guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2019. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements, along with the Accounting Standards Update 2018-03, Technical Corrections and Improvements to Financial Instruments Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2018-03”), which was issued in February 2018, and Accounting Standards Update 2018-04, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (“ASU 2018-04”), which was issued in March 2018. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers , now commonly referred to as Accounting Standards Codification Topic 606 (“ASC 606”). The FASB issued ASC 606 to clarify the principles for recognizing revenue and to devel

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Fair value hedges The Company transacts business in various foreign countries and is, therefore, subject to risk of foreign currency exchange rate fluctuations. The Company from time to time enters into forward contracts to economically hedge transactional exposure associated with commitments arising from trade accounts receivable, trade accounts payable and fixed purchase obligations denominated in a currency other than the functional currency of the respective operating entity. All derivative instruments are recorded on the Consolidated Balance Sheets at their respective fair values. The Company has elected not to prepare and maintain the documentation required to qualify for hedge accounting treatment and, therefore, changes in fair value are recorded in the Consolidated Statements of Operations. Net investment hedge During the fourth quarter of the fiscal year ended February 28, 2018 , the Company executed and settled with a third-party financial institution a forward contract to exchange €332.7 million for $391.9 million . The forward contract was designated a net investment hedge with the intent to mitigate the impact of foreign currency fluctuations between the Euro and the U.S. dollar on certain earnings from two of the Company’s Euro-based foreign subsidiaries. These earnings were repatriated during the fourth quarter of the fiscal year ended February 28, 2018 in response to the Tax Act enacted on December 22, 2017.

Income Taxes

Income Taxes	12 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Tax Act On December 22, 2017, the Tax Act was enacted into law. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, limitations on the deductibility of interest expense and executive compensation, elimination of the domestic production activities deduction and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system. U.S. GAAP requires companies to recognize the effect of tax law changes in the period of enactment. As a result, for the year ended February 28, 2018, the Company recognized a one-time tax charge of $122.7 million comprised of (i) income tax expense of $21.8 million due to the re-measurement of net deferred tax assets; (ii) income tax expense of $96.4 million related to the accrual of the transition tax; (iii) income tax expense of $1.8 million related to the accrual of withholding and other taxes due on future repatriation of cash; and (iv) income tax expense of $2.7 million related to re-measurement of interest and federal tax benefits on state positions related to the Company’s uncertain tax positions. In December 2017, the SEC staff issued Staff Accounting Bulletin 118 (“ SAB 118 ”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC Topic 740 —Income Taxes (“ASC 740”). The Company has calculated as final its re-measurement of deferred taxes and uncertain tax positions. While the Company has substantially completed its provisional analysis of the income tax effects of the Tax Act and recorded a reasonable estimate of such effects, the Company regards as provisional the transition tax, withholding and other taxes on future repatriation of cash, and the accounting for compensation accruals. These provisional tax effects may differ during the measurement period, possibly materially, due to further refinement of the calculations, changes in interpretations and assumptions made, and additional guidance that may be issued by the Department of the U.S. Treasury, the Internal Revenue Service, and other regulatory and standard setting bodies. The Company will complete its analysis within the next 12 months consistent with the guidance provided in SAB 118, and any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments are determined. The Tax Act lowered the federal corporate tax rate from 35% to 21%, effective January 1, 2018. As a fiscal year taxpayer, this provision, and certain others, impact the Company in the last quarter of the tax year, while other provisions will impact the Company beginning in the fiscal year ending February 28, 2019. In particular, the provision for the Company’s statutory federal income tax rate is 32.7% for the fiscal year ended February 28, 2018 as a result of this effective date rate change. The deemed repatriation transition tax (“Transition Tax”) is a tax on previously untaxed accumulated and current earnings and profits of certain foreign subsidiaries. The Company has not yet completed its accounting for the effects of the Transition Tax. However, the Company has made a reasonable estimate, and in the fourth quarter and fiscal year ended February 28, 2018, recognized provisional income tax expense of $96.4 million for the Transition Tax. The Company computed this amount based on currently available information; however, there is still uncertainty as to the application of the Tax Act, in particular as it relates to state income taxes. The Tax Act includes a provision designed to currently tax global intangible low-taxed income (“GILTI”). This GILTI provision is effective for the Company in the fiscal year ending February 28, 2019. The Company is evaluating available accounting policy alternatives to either record the U.S. income tax effect of future GILTI inclusions in the period in which they arise or establish deferred taxes with respect to the expected future tax liabilities associated with potential future GILTI inclusions. The Company has not yet made a policy election, but will make such election within the measurement period provided in SAB 118.

The tax holiday provides for a reduced tax rate on income attributable to research and development activities and is scheduled to terminate as of the fiscal year ending February 29, 2020. The financial impact from the tax holiday for the fiscal year ended February 28, 2018 resulted in an increase to the Company’s diluted earnings per share of approximately $0.01 . (2) Share-based compensation in the fiscal years ended February 28, 2018 and February 28, 2017 includes $27.0 million and $15.8 million , respectively, of net windfall tax benefits from share-based payments resulting from the Company’s adoption of ASU 2016-09 during the fiscal year ended February 28, 2017. These windfalls were offset by certain stock-based compensation for which the Company receives no tax benefit. (3) Deferred tax asset revaluation is a result of the Tax Act’s reduction in the U.S. corporate tax rate from 35% to 21%. Transition tax on foreign earnings is a mandatory one-time charge imposed by the Tax Act on accumulated earnings of foreign subsidiaries. Other includes $4.5 million of withholding tax and other one-time charges resulting from the enactment of the Tax Act. Deferred taxes Significant components of the Company’s deferred tax assets and liabilities consisted of the following (in thousands): February 28, 2018 February 28, 2017 Deferred tax assets: Foreign net operating loss carryforwards $ 6,031 $ 4,218 Domestic net operating loss carryforwards 14,736 5,696 Domestic credit carryforwards 14,963 9,864 Foreign credit carryforwards 4,522 1,200 Share-based compensation 32,086 51,016 Deferred revenue 83,427 97,258 Convertible notes 4,619 11,377 Other 12,916 18,382 Total deferred tax assets 173,300 199,011 Valuation allowance for deferred tax assets (4,228 ) (5,621 ) Total deferred tax assets, net of valuation allowance 169,072 193,390 Deferred tax liabilities: Goodwill 8,158 10,757 Property and equipment 15,811 25,163 Identifiable intangible assets 31,566 21,101 Compensation accruals 21,008 30,128 Other 4,204 4,347 Total deferred tax liabilities 80,747 91,496 Net deferred tax asset (1) $ 88,325 $ 101,894 _______________ (1) Net deferred tax asset is reported on the Company’s Consolidated Balance Sheets as of February 28, 2018 and February 28, 2017 as Deferred tax assets, net of $93.3 million and $104.8 million , respectively, and deferred tax liabilities included in Other long-term obligations of $5.0 million and $2.9 million , respectively. The Company maintains a valuation allowance against its deferred tax assets with respect to certain foreign and state NOL and credit carryforwards that the Company does not believe will ultimately be realized. For the fiscal year ended February 28, 2018 , the valuation allowance decrease d by $1.4 million primarily as a result of re-measuring certain components of the valuation allowance due to the Tax Act and due to changes related to foreign NOL and credit carryforwards where the realizability is now considered more likely than not. As of February 28, 2018 , the Company had U.S. federal NOL carryforwards of $45.6 million , foreign NOL carryforwards of $22.9 million and U.S. state NOL carryforwards of $64.9 million . The NOL carryforwards expire in varying amounts beginning in the fiscal year ending February 28, 2019 . As of February 28, 2018 , the Company had U.S. federal research tax credit carryforwards of $0.3 million , state research tax credit carryforwards of $14.7 million and foreign research tax credit carryforwards of $4.5 million , which expire in varying amounts beginning in the fiscal year ending February 28, 2019 . As of February 28, 2018 , cumulative undistributed earnings of non-U.S. subsidiaries totaled $226.0 million . It has been the Company’s historical policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. The Tax Act includes a provision to move the U.S. to a territorial tax system by imposing a transition tax on historic foreign earnings whether or not such earnings are repatriated to the U.S. In light of the new territorial tax system, the Company is reviewing its prior position on the reinvestment of the earnings of certain foreign subsidiaries and has provided for a $1.8 million deferred tax liability primarily related to foreign withholding taxes that may be incurred if such foreign earnings are repatriated. The Company continues to maintain an indefinite reinvestment assertion for the earnings in the majority of its foreign jurisdictions. Unrecognized tax benefits The following table reconciles unrecognized tax benefits (in thousands): February 28, 2018 February 28, 2017 February 29, 2016 Balance at beginning of year $ 76,902 $ 74,886 $ 60,343 Additions based on tax positions related to prior years 11,951 2,142 13,486 Additions based on tax positions related to the current year 7,628 4,893 3,494 (Reductions) additions related to changes in facts and circumstances (2,458 ) (2,271 ) 256 Reductions related to lapse of the statute of limitations (2,575 ) (2,748 ) (1,581 ) Reductions related to settlements with tax authorities (647 ) — (1,112 ) Balance at end of year $ 90,801 $ 76,902 $ 74,886 The Company’s unrecognized tax benefits as of February 28, 2018 and February 28, 2017 , which, if recognized, would affect the Company’s effective tax rate, were $80.4 million and $69.1 million , respectively. It is the Company’s policy to recognize interest and penalties related to uncertain tax positions as income tax expense. Uncertain tax position interest and penalties recognized in the Consolidated Statements of Operations totaled $0.5 million , $2.5 million and $1.5 million for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 , respectively. Uncertain tax position accrued interest and accrued penalties recognized in the Consolidated Balance Sheets totaled $13.7 million and $13.2 million as of February 28, 2018 and February 28, 2017 , respectively. Cumulative translation adjustments included in uncertain tax positions totaled $0.7 million as of February 28, 2018 . As of February 28, 2018 , it is reasonably possible that total unrecognized tax benefits may be reduced by up to $1.1 million within the next 12 months as a result of statutes of limitations expirations in various tax jurisdictions, all of which would affect the Company’s effective tax rate. The Company is subject to taxation in the U.S. and various other state and foreign jurisdictions. The material jurisdictions in which the Company is subject to potential examination include India, Ireland and the U.S., where the Company is no longer subject to examination prior to fiscal years ended February 28, 2006, February 29, 2012 and February 29, 2000, respectively. The Company is currently under examination in India, the United Kingdom, Germany and the U.S. The Company believes it has adequately provided for any reasonably foreseeable outcomes related to tax audits.

Convertible Notes

Convertible Notes	12 Months Ended
	Feb. 28, 2018
Debt Disclosure [Abstract]
Convertible Notes	Convertible Notes Convertible note offering On October 7, 2014, the Company completed its offering of $805.0 million aggregate principal amount of the convertible notes. The convertible notes were sold in a private placement under a purchase agreement, dated as of October 1, 2014, entered into by and among the Company and the initial purchasers, for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Indenture On October 7, 2014, the Company entered into an indenture (the “Indenture”) with respect to the convertible notes with U.S. Bank National Association, as trustee (the “Trustee”). Under the Indenture, the convertible notes are senior unsecured obligations of the Company and bear interest at a rate of 0.25% per year, payable semiannually in arrears on April 1 and October 1 of each year, beginning on April 1, 2015. The convertible notes will mature on October 1, 2019, unless previously purchased or converted. The convertible notes are convertible into shares of the Company’s common stock at an initial conversion rate of 13.6219 shares per $1,000 principal amount of the convertible notes (which is equivalent to an initial conversion price of approximately $73.41 per share), subject to adjustment upon the occurrence of certain events. Upon conversion of the convertible notes, holders will receive cash or shares of the Company’s common stock or a combination thereof, at the Company’s election. At their option, holders may convert their convertible notes prior to the close of business on the business day immediately preceding April 1, 2019, only upon the occurrence of certain circumstances. For example, during any fiscal quarter commencing after the fiscal quarter ended on November 30, 2014 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price, the convertible notes become convertible at the holders’ option. The price of the Company’s common stock was greater than or equal to 130% of the conversion price, which is $95.43 , for at least 20 trading days during the 30 consecutive trading days ending on the last trading day of the fiscal quarters ended August 31, 2017, November 30, 2017 and February 28, 2018 . Therefore, as of February 28, 2018 , the convertible notes remain convertible at the holders’ option until May 31, 2018. On and after April 1, 2019, holders may convert their convertible notes at any time until the close of business on the second scheduled trading day immediately preceding the maturity date of the convertible notes. During the fourth quarter of the fiscal year ended February 28, 2018 , the Company settled notices of conversion with respect to $28 thousand aggregate principal amount of the convertible notes and elected to settle such conversions by paying cash for the principal amount and issuing 155 shares of common stock for the excess conversion value. Total settled conversions as of February 28, 2018 amounted to $34 thousand aggregate principal amount of the convertible notes. The Company expects to settle conversions of $26.0 million in principal amount of the convertible notes in the first quarter of the fiscal year ending February 28, 2019 by paying cash for the principal amount and issuing shares of common stock for the excess conversion value. The Company continues to receive conversion requests and as of April 24, 2018 , such incremental requests totaled $96.8 million in principal amount of the convertible notes. Based on the closing price of the Company’s common stock of $147.40 on the last trading day of the fourth quarter of the fiscal year ended February 28, 2018 , the if-converted value of the convertible notes as of February 28, 2018 exceeded their principal amount by approximately $811.3 million . The Company continues to classify the net carrying amount of the convertible notes as a long-term liability, except for $23.8 million , classified as current and expected to be cash-settled within the next fiscal quarter. The equity component of the convertible notes will continue to be classified as additional paid-in capital because the Company has the option to settle the principal amount in shares and the convertible notes’ maturity date is more than 12 months away. However, it is the Company’s intent to settle the principal amount of the convertible notes in cash. The conversion rate is subject to customary anti-dilution adjustments. If certain corporate events described in the Indenture occur prior to the maturity date, the conversion rate will be increased for a holder who elects to convert its convertible notes in connection with such corporate event in certain circumstances. The convertible notes are not redeemable prior to maturity, and no sinking fund is provided for the notes. If the Company undergoes a “fundamental change,” as defined in the Indenture, subject to certain conditions, holders may require the Company to purchase for cash all or any portion of their convertible notes. The fundamental change purchase price will be 100% of the principal amount of the convertible notes to be purchased plus any accrued and unpaid special interest up to but excluding the fundamental change purchase date. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or the holders of at least 25% in principal amount of the outstanding convertible notes may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the convertible notes to be due and payable. In accounting for the issuance of the convertible notes, the Company separated the convertible notes into liability and equity components. The Company allocated the total transaction costs incurred to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component are being amortized to interest expense over the term of the convertible notes. The excess of the face value of the convertible notes as a whole over the carrying amount of the liability component (the “debt discount”) is being amortized to interest expense over the term of the convertible notes. As of February 28, 2018 and February 28, 2017 , the convertible notes consisted of the following (in thousands): February 28, 2018 February 28, 2017 Liability component: Principal $ 804,966 $ 805,000 Less: debt issuance costs (4,695 ) (7,442 ) Less: debt discount (32,271 ) (51,925 ) Net carrying amount $ 768,000 $ 745,633 Equity component (1) $ 96,890 $ 96,890 ________________ (1) Recorded in the Consolidated Balance Sheets in Additional paid-in capital. The following table includes total interest expense recognized related to the convertible notes for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Coupon rate 0.25% per year, payable semiannually $ 2,012 $ 2,012 $ 2,012 Amortization of convertible note issuance costs — liability component 2,747 2,587 2,433 Accretion of debt discount 19,654 19,104 18,570 Total interest expense related to convertible notes $ 24,413 $ 23,703 $ 23,015 The fair value of the convertible notes, which was determined based on inputs that are observable in the market (Level 2), and the carrying value of convertible notes (the carrying value excludes the equity component of the convertible notes classified in equity) is as follows (in thousands): February 28, 2018 Fair Value Carrying Value Convertible notes $ 778,014 $ 768,000 Convertible note hedge transactions and warrant transactions On October 1, 2014, the Company entered into convertible note hedge transactions and warrant transactions with certain of the initial purchasers of the convertible notes or their respective affiliates. In connection with the conversions of the convertible notes that settled in the fiscal year ended February 28, 2018 , the Company exercised a portion of the options that are part of the convertible note hedge transactions for 179 shares of the Company’s common stock. The convertible note hedge transactions are expected to offset, to the extent the Company’s common stock per share price does not exceed $101.65 , the potential dilution with respect to shares of the Company’s common stock upon any conversion of the convertible notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted notes, as the case may be. To partially offset the $148.0 million cost of the convertible note hedge transactions, the Company issued warrants and received proceeds of $79.8 million . The number of shares of the Company’s common stock underlying the warrants total 10,965,630 , the number of shares originally underlying the convertible notes and the convertible note hedge transactions. The combination of the convertible note hedge transactions and the warrant transactions effectively increases the initial conversion price of the convertible notes from $73.41 per share to $101.65 per share. As a result, the warrant transactions will have a dilutive effect with respect to the Company’s common stock to the extent that the market price per share of the Company’s common stock, as measured under the terms of the warrant transactions, exceeds the $101.65 strike price of the warrants. For the fiscal year ended February 28, 2018 , the warrants were included in the computation of diluted shares outstanding because the warrants’ exercise price was less than the average market price of the Company’s common stock during the related period. However, subject to certain conditions, the Company may elect to settle all of the warrants in cash.

In each of these circumstances, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party’s claims. Further, the Company’s obligations under these agreements may in certain cases be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third-parties for certain payments made by the Company. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company’s obligations and the facts and circumstances involved in each particular agreement. The Company does not record a liability for claims related to indemnification unless the Company concludes that the likelihood of a material claim is probable and estimable. Payments pursuant to these indemnification claims during the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 were, in the aggregate, immaterial.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company computes basic net income per common share by dividing net income available to common stockholders by the weighted average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. Potential common share equivalents consist of shares issuable upon the exercise of stock options or vesting of share-based awards. The following table reconciles the numerators and denominators of the earnings per share (“EPS”) calculation (in thousands, except per share amounts): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Net income, basic and diluted $ 258,803 $ 253,703 $ 199,365 Weighted average common shares outstanding 177,150 179,642 182,817 Incremental shares attributable to assumed vesting or exercise of outstanding equity award shares 3,456 3,027 3,020 Dilutive effect of convertible notes 3,445 292 282 Dilutive effect of warrants 551 — — Diluted shares 184,602 182,961 186,119 Diluted net income per share $ 1.40 $ 1.39 $ 1.07 With respect to the Company’s convertible notes, the Company has the option to pay cash or deliver, as the case may be, either cash, shares of its common stock or a combination of cash and shares of its common stock for the aggregate amount due upon conversion of the convertible notes. The Company’s intent is to settle the principal amount of the convertible notes in cash upon conversion. As a result, upon conversion of the convertible notes, only the amounts payable in excess of the principal amounts of the convertible notes are considered in diluted EPS under the treasury stock method. See NOTE 11 —Convertible Notes for detailed information on the convertible notes. Warrants to purchase 10,965,630 shares of the Company’s common stock at $101.65 per share were outstanding during the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 . For the fiscal year ended February 28, 2018 , warrants were included in the computation of diluted EPS because the warrants’ exercise price was less than the average market price of the Company’s common stock during the related period. The following share awards are not included in the computation of diluted EPS because the aggregate value of proceeds considered received upon either exercise or vesting was greater than the average market price of the Company’s common stock during the related periods and the effect of including such share awards in the computation would be anti-dilutive (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Number of shares considered anti-dilutive for calculating diluted EPS 269 77 21

Share-based Awards	Share-based Awards Overview The Company’s 2004 Long-Term Incentive Plan, as amended and restated (the “LTIP”), provides for the granting of service- and performance-based share awards, among other awards. As of February 28, 2018 , there were 8.5 million shares of common stock reserved for issuance under the LTIP for future share-based awards to be granted to any employee, officer, director or consultant of the Company at terms and prices to be determined by the Board of Directors. The following table summarizes the Company’s share-based awards granted, by type: Awards Granted in Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Shares and Shares Underlying Awards Weighted Average Per Share Award Fair Value Shares and Shares Underlying Awards Weighted Average Per Share Award Fair Value Shares and Shares Underlying Awards Weighted Average Per Share Award Fair Value Service-based shares and share units (1) 1,792,655 $ 102.33 2,212,006 $ 75.62 2,108,639 $ 76.45 Performance share units—Maximum 523,520 $ 87.99 725,004 $ 76.68 628,596 $ 77.87 Assumed — $ — — $ — 119,515 $ 58.22 Total share-based awards 2,316,175 $ 99.09 2,937,010 $ 75.88 2,856,750 $ 76.00 _______________ (1) Certain executives were granted restricted stock awards totaling 104,362 shares, 140,182 shares and 154,705 shares for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 , respectively, that were awarded subject to both a four -year service condition and the achievement of a specified dollar amount of revenue for the fiscal year in the year of grant (the “RSA performance goal”). The RSA performance goal for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 were met. Therefore, as of February 28, 2018 , only the service condition remained with 25% vesting on or about July 16 following the year of grant and the remainder vesting ratably on a quarterly basis over the course of the subsequent three -year period, provided that the grantee’s business relationship with the Company has not ceased. The following summarizes share-based compensation expense recognized in the Company’s Consolidated Financial Statements (in thousands): Fiscal Years Ended February 28, 2018 (1) February 28, 2017 February 29, 2016 Cost of revenue $ 16,862 $ 16,553 $ 15,898 Sales and marketing 87,158 93,378 69,089 Research and development 57,008 52,424 48,466 General and administrative 31,221 30,175 32,781 Total share-based compensation expense (1) $ 192,249 $ 192,530 $ 166,234 _______________ (1) Total share-based compensation expense for the fiscal years ended February 28, 2018 and February 28, 2017 included $12.7 million and $5.0 million , respectively, of expense related to the Company’s employee stock purchase plan (“ESPP”). See NOTE 18 —Employee Benefit Plans for information regarding the ESPP. Share-based compensation expense qualifying for capitalization was insignificant for each of the Company’s fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 . Accordingly, no share-based compensation expense was capitalized during these years. The Company recognizes share-based award forfeitures only as they occur rather than estimating by applying a forfeiture rate. During the fiscal year ended February 29, 2016, an estimated forfeiture rate of 10% per annum, which approximated the Company’s historical rate, was applied to options and service-based share awards. Awards were adjusted to actual forfeiture rates at vesting. Stock options The total share-based compensation expense related to stock options recognized in the Consolidated Financial Statements was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Share-based compensation expense—stock options $ 2,302 $ 4,813 $ 4,918 As of February 28, 2018 , the Company had 76,214 stock options outstanding with a weighted average remaining contractual life of 4.4 years and a weighted average exercise price of $29.45 . The number of stock options exercisable as of February 28, 2018 was 54,155 with a weighted average share price of $26.65 . The intrinsic value of stock options exercised was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Total intrinsic value of stock options exercised $ 7,849 $ 7,928 $ 9,103 As of February 28, 2018 , compensation cost related to unvested stock options not yet recognized in the Company’s Consolidated Financial Statements totaled $0.9 million . The weighted average period over which these unvested stock options are expected to be recognized is approximately 1.5 years . Service-based share awards Service-based share awards include nonvested shares, nonvested share units and deferred share units granted under the LTIP. Nonvested shares vest, subject to continued service to the Company, 25% on the first trading day on or about July 16 of the year subsequent to the year in which the grant occurs and 6.25% on the last day of each subsequent three-month period. Nonvested share units generally vest, subject to continued service to the Company, 25% each year over a four -year period beginning on the date of grant. Nonvested shares and nonvested share units are generally amortized to expense on a straight-line basis over four years. Deferred share units are awarded to directors and generally vest within one year when issued in lieu of annual share awards or immediately when issued in lieu of cash. The total share-based compensation expense related to service-based share awards recognized in the Company’s Consolidated Financial Statements was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Share-based compensation expense—service-based awards $ 139,721 $ 147,843 $ 124,904 The following table summarizes the activity for the Company’s service-based share awards: Nonvested Weighted Average Service-based share awards at February 28, 2015 6,378,719 $ 51.49 Granted 2,108,639 76.45 Vested (2,047,169 ) 50.78 Forfeited (265,315 ) 56.21 Service-based share awards at February 29, 2016 6,174,874 $ 60.05 Granted 2,212,006 75.62 Vested (2,409,518 ) 57.42 Forfeited (313,162 ) 64.36 Service-based share awards at February 28, 2017 5,664,200 $ 67.01 Granted 1,792,655 102.33 Vested (2,345,193 ) 61.93 Forfeited (322,677 ) 75.36 Service-based share awards at February 28, 2018 4,788,985 $ 82.16 The following summarizes the intrinsic value as of February 28, 2018 of the Company’s service-based awards outstanding: Number of Weighted Average Intrinsic Value at February 28, 2018 (in thousands) Outstanding 4,788,985 2.7 years $ 705,896 The intrinsic value of service-based awards vesting was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Total intrinsic value of service-based awards vesting $ 244,035 $ 181,691 $ 157,864 As of February 28, 2018 , compensation cost related to service-based share awards not yet recognized in the Company’s Consolidated Financial Statements totaled $303.6 million . The weighted average period over which these nonvested awards are expected to be recognized is approximately 2.7 years . Performance-based share awards Under the LTIP, certain executive officers and senior management were awarded a target number of PSUs. The PSU payouts are either based on (i) the Company’s financial performance (“performance condition”) or (ii) the performance of the Company’s total stockholder return (“market condition”). Set forth below are general descriptions of the two types of performance-based awards granted to certain executive officers and members of senior management. PSUs with performance conditions Depending on the Company’s financial performance measured against the financial performance of specified peer companies during a three -year performance period, PSU grantees may earn up to 200% of the target number of PSUs (the “Maximum PSUs”). Payouts are earned over a performance period with two separate performance segments. Up to 50% of the Maximum PSUs may be earned in respect of the first performance segment; and up to 100% of the Maximum PSUs may be earned in respect of the second performance segment, less the amount earned in the first performance segment. PSUs with market conditions Depending on the performance of the Company’s total stockholder return measured against the performance of the total shareholder return of specified peer companies over a performance period of approximately three years, PSU grantees may earn up to 200% of the target number of PSUs. Each grantee will receive a number of shares of common stock equal to the number of PSUs earned in a single payout following the end of the performance period. In addition to the PSUs with the market condition described above, certain executives were awarded a total of 242,352 PSUs that pay out only if the Company’s total shareholder return increased by at least 50% within a three -year performance period beginning on August 6, 2014 (“TSR Hurdle PSUs”). If the performance goal was achieved during the performance period and the grantee’s business relationship with the Company had not ceased, 50% of the TSR Hurdle PSUs vested upon achievement of the performance goal and the remaining 50% of the TSR Hurdle PSUs vest on the last day of the four -year service period beginning on August 6, 2014. The TSR Hurdle PSUs’ performance goal was met during the fourth quarter of the fiscal year ended February 29, 2016. The total share-based compensation expense related to performance-based share awards recognized in the Company’s Consolidated Financial Statements was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Share-based compensation expense—performance-based awards $ 37,480 $ 34,865 $ 36,412 The following table summarizes the activity for the Company’s PSUs: Maximum (1) Shares Weighted Average Outstanding at February 28, 2015 2,149,335 $ 51.01 Granted 628,596 77.87 Vested (497,656 ) 52.41 Forfeited (230,764 ) 52.29 Outstanding at February 29, 2016 2,049,511 $ 58.76 Granted 725,004 76.68 Vested (492,518 ) 48.94 Forfeited (346,102 ) 62.68 Outstanding at February 28, 2017 1,935,895 $ 67.27 Granted 523,520 87.99 Vested (559,466 ) 57.96 Forfeited (247,346 ) 53.85 Outstanding at February 28, 2018 1,652,603 $ 78.99 _______________ (1) Vested and forfeited amounts represent the actual number of shares vesting and forfeited during the year. Outstanding amounts represent the remaining maximum potential shares available to vest as of the period ended. The total intrinsic value of performance-based share awards vesting was as follows (in thousands): Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Total intrinsic value of performance-based awards vesting $ 48,884 $ 36,768 $ 36,555 As of February 28, 2018 , the number of shares subject to PSU awards expected to vest was 1.1 million shares. Compensation expense related to PSUs expected to vest but not yet recognized in the Consolidated Financial Statements totaled $28.9 million as of February 28, 2018 . The weighted average period over which these awards are expected to be recognized is approximately 1.1 years .

Business Combinations [Abstract]
Business Combinations	Business Combinations Acquisition of CoreOS, Inc. On January 30, 2018, the Company completed the acquisition of all of the shares of CoreOS, Inc. (“CoreOS”). The addition of CoreOS, a provider of Kubernetes and container-native solutions, is expected to further enable the Company’s customers to build any application and deploy them in any environment with the flexibility afforded by open source. By combining CoreOS’s complementary capabilities with the Company’s Kubernetes and container-based portfolio, including Red Hat OpenShift, the Company aims to further accelerate adoption and development of its hybrid cloud platform for modern application workloads. The consideration paid was $238.6 million in cash. Based on management’s provisional assessment of the acquisition-date fair value of the assets acquired and liabilities assumed, the total consideration transferred of $238.6 million was allocated to the Company’s assets and liabilities on a preliminary basis as follows: $163.2 million to goodwill, $76.9 million to identifiable intangible assets and $1.5 million to working capital as a net current liability. Acquisition of Permabit Technology Corporation On July 31, 2017, the Company acquired the assets and technology of Permabit Technology Corporation (“Permabit”), a provider of software for data deduplication, compression and thin provisioning technology. Adding Permabit’s data deduplication and compression capabilities to the Company’s Red Hat Enterprise Linux platform will better enable enterprise digital transformation through more efficient storage options. During the three months ended February 28, 2018, the Company completed its assessment of the acquisition-date fair value of the assets acquired and liabilities assumed. The total consideration transferred of $49.8 million was allocated to the Company’s assets and liabilities as follows: $39.4 million to goodwill, $10.4 million to identifiable intangible assets and a nominal amount to working capital. The goodwill acquired is expected to be deductible for tax purposes. Acquisition of Codenvy S. A. On June 1, 2017, the Company completed its acquisition of all of the shares of Codenvy S.A. (“Codenvy”), a provider of cloud-native development tools that enable developers to more easily create modern container-based and cloud-native applications. By adding Codenvy to its existing portfolio of developer tools and application platforms, including Red Hat JBoss Middleware and Red Hat OpenShift, the Company continues its efforts to provide solutions that enable developers to create applications for hybrid cloud environments. The Company plans to make Codenvy an integral part of OpenShift.io, the Company’s recently announced hosted development environment for building hybrid cloud services on OpenShift. During the three months ended November 30, 2017, the Company completed its assessment of the acquisition-date fair value of the assets acquired and liabilities assumed. The total consideration transferred of $34.2 million was allocated to the Company’s assets and liabilities as follows: $25.4 million to goodwill, $11.3 million to identifiable intangible assets and $2.5 million to working capital as a net current liability. Acquisition of 3scale, Inc. On June 24, 2016, the Company completed its acquisition of all of the shares of 3scale, Inc. (“3scale”), a provider of application programming interface (“API”) management technology. By adding 3scale to its existing portfolio, including Red Hat JBoss Middleware, Red Hat OpenShift and Red Hat Mobile Application Platform, the Company strengthened its enablement of the API economy with simplified cloud integration and microservices-based architectures. The consideration paid was $29.1 million in cash. Management has completed its assessment of the acquisition-date fair value of the assets acquired and liabilities assumed. The total consideration transferred of $29.1 million was allocated to the Company’s assets and liabilities as follows: $16.9 million to goodwill, $13.1 million to identifiable intangible assets and $0.9 million to working capital as a net current liability. Acquisition of Ansible, Inc. On October 16, 2015, the Company completed its acquisition of all of the shares of Ansible, Inc. (“Ansible”). Ansible is a provider of IT automation solutions that allows its users to manage applications across hybrid cloud environments. The acquisition augments the Company’s management portfolio and help customers to deploy and manage applications across private and public clouds, speed service delivery through development and operations initiatives, streamline OpenStack installations and upgrades and accelerate container adoption by simplifying orchestration and configuration. The consideration paid was $126.0 million and includes $125.2 million of cash. Management has completed its assessment of the acquisition-date fair value of the assets acquired and liabilities assumed. The total consideration transferred of $126.0 million has been allocated to the Company’s assets and liabilities as follows: $102.3 million to goodwill, $25.1 million to identifiable intangible assets and $1.4 million to working capital as a net current liability. Transaction costs The Company incurred transaction costs, including legal and accounting fees, relating to these acquisitions, which have been expensed as incurred and included in General and administrative expense on the Company’s Consolidated Statements of Operations. For the fiscal year ended February 28, 2018, transaction costs relating to the CoreOS, Permabit and Codenvy acquisitions totaled approximately $2.0 million ; for the fiscal year ended February 28, 2017, transaction costs relating to the 3scale acquisition totaled approximately $1.8 million ; and for the fiscal year ended February 29, 2016, transactions costs relating to the Ansible acquisition totaled approximately $3.9 million . Pro forma consolidated financial information (unaudited) The following unaudited pro forma consolidated financial information reflects the results of operations of the Company (in thousands, except per share amounts) as if the acquisitions of CoreOS, Permabit, Codenvy, 3scale and Ansible had occurred as of the beginning of the fiscal year prior to the fiscal year of acquisition, after giving effect to certain purchase accounting adjustments. These pro forma results are not necessarily indicative of what the Company’s operating results would have been had the acquisitions actually taken place at the beginning of the fiscal year prior to the fiscal year of acquisition. Fiscal Years Ended February 28, 2018 February 28, 2017 February 29, 2016 Revenue $ 2,930,237 $ 2,419,418 $ 2,057,565 Net income $ 231,808 $ 226,717 $ 188,825 Basic net income per common share $ 1.31 $ 1.26 $ 1.03 Diluted net income per common share $ 1.26 $ 1.24 $ 1.01 Goodwill and other business combinations The Company completed its annual goodwill impairment tests for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016. No goodwill impairment was deemed to have occurred for any of the fiscal years. The following is a summary of goodwill (in thousands): February 28, 2018 February 28, 2017 February 29, 2016 Balance at beginning of year $ 1,040,709 $ 1,027,277 $ 927,060 Acquisitions 228,451 16,923 102,260 Impact of foreign currency fluctuations 20,080 (3,636 ) (3,493 ) Other adjustments (410 ) 145 1,450 Balance at end of year $ 1,288,830 $ 1,040,709 $ 1,027,277 The excess of purchase price paid for CoreOS, Permabit, Codenvy and other acquisitions over the fair value of the net assets acquired was recognized as goodwill. Goodwill comprises the majority of the purchase price paid for each of the acquired businesses because these businesses were focused on emerging technologies such as development and operations automation, mobile technologies, cloud-enabling technologies and software-defined storage technologies, which consequently—at the time of acquisition—generated relatively little revenue. However, these acquired businesses, with their assembled, highly-specialized workforces and community of contributors, are expected to both expand the Company’s existing technology portfolio and advance the Company’s market position overall in open source solutions.

Summary of Significant Accoun32

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying Consolidated Financial Statements include the accounts of the Company and all of its wholly owned subsidiaries. All significant inter-company accounts and transactions are eliminated in consolidation. There are no significant foreign exchange restrictions on the Company’s foreign subsidiaries. The Consolidated Statement of Cash Flows for the year ended February 29, 2016 includes the effect of retrospective application of Accounting Standards Update 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). Under ASU 2016-09, all windfall tax benefits related to share-based payments are reported as cash flows from operating activities along with all other income tax cash flows. Previously, windfall tax benefits from share-based payment arrangements were reported as cash flows from financing activities. With the Company’s permitted election to retrospectively apply this classification amendment, $20.2 million of windfall tax benefits previously reported as cash inflows from financing activities on the Company’s Consolidated Statement of Cash Flows for the fiscal year ended February 29, 2016 have been reclassified as cash inflows from operating activities. Prior to adopting ASU 2016-09, the Company credited windfall tax benefits related to share-based compensation to Additional paid-in capital in the Company’s Consolidated Balance Sheets. Under ASU 2016-09, these windfalls are recognized as a discrete tax benefit in the Company’s Consolidated Statements of Operations. ASU 2016-09 requires companies to adopt the amendment relating to accounting for windfalls and shortfalls on a prospective basis only. As a result, no change has been made to the Consolidated Statements of Operations for the fiscal year ended February 29, 2016 related to the $19.8 million of net windfall tax benefits the Company recognized as additional paid-in capital during the fiscal year ended February 29, 2016. For additional discussion related to recent accounting pronouncements the Company has either recently adopted or is currently evaluating the impact from future adoption, see “Recent accounting pronouncements” in this note. In addition to the reclassifications resulting from application of ASU 2016-09, certain other amounts for the fiscal years ended February 28, 2017 and February 29, 2016 have been reclassified to conform to the current year presentation.
Use of estimates	Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from such estimates. Estimates are used for, but not limited to, revenue recognition, goodwill and other long-lived assets, share-based compensation, income taxes and loss contingencies.
Revenue recognition	Revenue recognition The Company establishes persuasive evidence of a sales arrangement for each type of revenue transaction based on either a signed contract with the end customer, a click-through contract on the Company’s website whereby the customer agrees to the Company’s standard subscription terms, signed or click-through distribution contracts with original equipment manufacturers (“OEMs”) and other resellers, or, in the case of individual training seats, through receipt of payment that indicates acceptance of the Company’s training agreement terms. Subscription revenue Subscription revenue is comprised of direct and indirect sales of subscriptions relating to Red Hat technologies. Accounts receivable and deferred revenue are recorded at the time a customer enters into a binding subscription agreement for the purchase of a subscription, subscription services are made available to the customer and the customer is billed. The deferred revenue amount is recognized as revenue ratably over the subscription period. Red Hat technologies are generally offered with either one - or three -year base subscription periods; the majority of the Company’s subscriptions have one-year terms. Under these subscription agreements, renewal rates are generally specified for one or three -year renewal terms. Subscriptions generally entitle the end user to the technology itself and post-contract customer support, generally consisting of varying levels of support services as well as access to security updates, fixes, functionality enhancements, upgrades to the technologies, each on an if and when available basis, and compatibility with an ecosystem of certified hardware and software, during the term of the subscription. The Company sells its offerings through two principal channels: (1) direct, which includes sales by the Company’s sales force as well as web store sales, and (2) indirect, which includes certified cloud and service providers (“CCSPs”), distributors, OEMs, systems integrators and value added resellers. The Company recognizes revenue from the sale of Red Hat technologies ratably over the period of the subscription beginning on the commencement date of the subscription agreement. Subscription arrangements with large enterprise customers often have contracts with multiple elements (e.g., software technology, support, training, consulting and other services). The Company allocates revenue to each element of the arrangement based on vendor-specific objective evidence (“VSOE”) of each element’s fair value when the Company can demonstrate sufficient evidence of the fair value of at least those elements that are undelivered. The fair value of each element in multiple element arrangements is created by either (i) providing the customer with the ability during the term of the arrangement to renew that element at the same rate paid for the element included in the initial term of the agreement or (ii) selling the element on a stand-alone basis. The Company derives a portion of its revenue from CCSPs that provide public clouds with, and allow users to consume, computing resources as a service. The Company earns revenue based on subscription units consumed by the CCSP or its end users. The Company uses its historical cloud-usage data to estimate the amount of revenue earned and recognized each month and adjusts to actual amounts earned upon receipt of usage reports from the CCSPs in the following month. Training and services revenue Training and services revenue is comprised of revenue for consulting, engineering and customer training and education services. Consulting services consist of time-based arrangements, and revenue is recognized as these services are performed. Engineering services represent revenue earned under fixed fee arrangements with the Company’s OEM partners and other customers to provide for significant modification and customization of Red Hat technologies. The Company recognizes revenue for these fixed fee engineering services using the percentage of completion basis of accounting, provided the Company has the ability to make reliable estimates of progress towards completion, the fee for such services is fixed or determinable and collection of the resulting receivable is probable. Under the percentage of completion method, earnings under the contract are recognized based on the progress toward completion as estimated using the ratio of labor hours incurred to total expected project hours. Changes in estimates are recognized in the period in which they are known. Revenue for customer training and education services is recognized on the dates the services are complete.
Deferred selling costs	Deferred selling costs Deferred commissions are the incremental costs that are directly associated with non-cancellable subscription contracts with customers and consist of sales commissions paid to the Company’s sales force. The commissions are deferred and amortized over a period that approximates the subscription period. The commission payments are paid in full subsequent to the month in which the customer’s service commences. The deferred commission amounts are recoverable through the future revenue streams under the non-cancellable customer contracts. In addition, the Company has the ability and intent under the commission plans with its sales force to recover commissions previously paid to its sales force in the event that customers breach the terms of their subscription agreements and do not fully pay for their subscription agreements. Deferred commissions are included in Prepaid expenses and Other assets, net on the accompanying Consolidated Balance Sheets. Amortization of deferred commissions is included in sales and marketing expense in the accompanying Consolidated Statements of Operations.
Goodwill and other long-lived assets	Goodwill and other long-lived assets Goodwill The Company evaluates goodwill for impairment during the fourth quarter of its fiscal year or more frequently if events or changes in circumstances indicate that an impairment to goodwill may have occurred. For fiscal years ended February 28, 2018 and February 28, 2017, the Company applied its test for goodwill impairment as permitted by Accounting Standards Update 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment (“ASU 2011-08”), which allows the Company to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying value. The outcome of these qualitative tests determines whether it is necessary to proceed with a quantitative impairment assessment. After considering such qualitative factors as macroeconomic conditions, actual or anticipated changes to cost factors (for example, selling and delivery), overall financial performance and other Company-specific factors, such as potential changes in strategy, the Company determined that it was not more likely than not that any impairment to goodwill had occurred during the fiscal years ended February 28, 2018 and February 28, 2017. For the fiscal year ended February 29, 2016, the Company elected to perform a quantitative assessment of goodwill for all of its reporting units. In doing so, the Company compared the estimated fair value of each of the reporting units to its respective book value, including allocated goodwill. The Company concluded that there were no impairments of goodwill. Other long-lived assets The Company evaluates the recoverability of its property and equipment and other long-lived assets whenever events or changes in circumstances indicate that an impairment may have occurred. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or the business to which the assets relate. Impairment losses, if any, are measured as the amount by which the carrying value exceeds the fair value of the assets.
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash The Company considers highly liquid investments purchased with a maturity period of three months or less at the date of purchase to be cash equivalents. The Company’s restricted cash totaled $4.2 million and $3.1 million at February 28, 2018 and February 28, 2017 , respectively, and includes cash restricted as part of collateral for certain office facilities. Restricted cash is included with Cash, cash equivalents and restricted cash on the Company’s Consolidated Balance Sheets.
Accounts receivable and allowance for doubtful accounts	Accounts receivable and allowance for doubtful accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on historical write-off experience. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when the Company determines it is probable the receivable will not be recovered. The Company does not have off-balance sheet credit exposure related to its customers.
Fair value measurements	Fair value measurements Fair value is defined as the exchange price that would be received for the purchase of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for such asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value should maximize the use of observable inputs and minimize the use of unobservable inputs. To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. The Company’s investments are comprised primarily of debt securities that are classified as available for sale and recorded at their fair values. Liquid investments with effective maturities of three months or less at the date of purchase are classified as cash equivalents. Investments with remaining effective maturities of twelve months or less from the balance sheet date are classified as short-term investments. Investments with remaining effective maturities of more than twelve months from the balance sheet date are classified as long-term investments. The Company’s Level 1 financial instruments are valued using quoted prices in active markets for identical instruments. The Company’s Level 2 financial instruments, including derivative instruments, are valued using quoted prices for identical instruments in less active markets or using other observable market inputs for comparable instruments. Unrealized gains and temporary losses on investments classified as available for sale are included within accumulated other comprehensive income, net of any related tax effect. Realized gains and losses are recorded using the specific identification method and upon realization, such amounts are reclassified from accumulated other comprehensive income to Other income (expense), net. Realized gains and losses and other than temporary impairments, if any, are reflected in the Company’s Consolidated Statements of Operations as Other income (expense), net. The Company does not recognize changes in the fair value of its investments in income unless a decline in value is considered other than temporary. The vast majority of the Company’s investments are priced by pricing vendors. These pricing vendors use the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs. In the event observable inputs are not available, the Company assesses other factors to determine the security’s market value, including broker quotes or model valuations. Independent price verifications of all holdings are performed by pricing vendors that are then reviewed by the Company. In the event a price fails a pre-established tolerance check, it is researched so that the Company can assess the cause of the variance to determine what the Company believes is the appropriate fair value. See NOTE 19 —Assets and Liabilities Measured at Fair Value on a Recurring Basis for further discussion on fair value measurements. The Company minimizes its credit risk associated with investments by investing primarily in investment grade, liquid securities. The Company’s policy is designed to limit exposures to any one issuer depending on credit quality. Periodic evaluations of the relative credit standing of those issuers are considered in the Company’s investment strategy.
Internal use software	Internal use software The Company capitalizes costs related to the development of internal use software for its website, enterprise resource planning system and systems management applications. The Company amortizes the costs of computer software developed for internal use on a straight-line basis over an estimated useful life of five years. The carrying value of internal use software is included in property and equipment on the Company’s Consolidated Balance Sheets.
Capitalized software costs	Capitalized software costs Capitalization of software development costs for products to be sold to third parties begins upon the establishment of technological feasibility and ceases when the product is available for general release. As a result of the Company’s practice of frequently releasing source code that it has developed on an on-going basis for unrestricted download on the Internet, there is generally no passage of time between achievement of technological feasibility and the availability of the Company’s product for general release.
Property and equipment	Property and equipment Property and equipment is primarily comprised of furniture, computer and other equipment, computer software and leasehold improvements, which are recorded at cost and depreciated or amortized using the straight-line method. Expenditures for maintenance and repairs are charged to operations as incurred; major expenditures for renewals and betterments are capitalized and depreciated. Property and equipment acquired under capital leases are depreciated over the lesser of the estimated remaining useful life of the asset or the remaining term of the lease.
Share-based compensation	Share-based compensation The Company measures share-based compensation cost as of the grant date, based on the estimated fair value of the award and recognizes the cost over the employee requisite service period typically on a straight-line basis. The Company estimates the fair value of stock options using the Black-Scholes-Merton valuation model. The fair value of nonvested share awards, nonvested share units and performance share units (“PSUs”) are measured at their underlying closing share price on the date of grant.
Selling and marketing expenses	Sales and marketing expenses Sales and marketing expenses consist of costs, including salaries, sales commissions and related expenses, such as travel, of all personnel involved in the sales and marketing process. Sales and marketing expenses also include costs of advertising, sales lead generation programs, cooperative marketing arrangements and trade shows. Payments made to resellers or other customers are recognized as a reduction of revenue unless the Company (i) receives an identifiable benefit (goods or services) in exchange for such payments that is sufficiently separable from the purchase of the Company’s products and (ii) the Company can reasonably estimate the fair value of the benefit identified. Advertising costs are expensed as incurred.
Research and development expenses	Research and development expenses Research and development expenses include all direct costs, primarily salaries for Company personnel and outside consultants, related to the development of new software products, significant enhancements to existing software products, and the portion of costs of development of internal use software required to be expensed. Research and development costs are charged to operations as incurred.
Income taxes	Income taxes The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company continues to assess the realizability of its deferred tax assets, which primarily consist of share-based compensation expense deductions, tax credit carryforwards and deferred revenue. In assessing the realizability of these deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The Company continues to maintain a valuation allowance against its deferred tax assets with respect to certain foreign net operating loss (“NOL”) carryforwards. With respect to foreign earnings, it has been the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law. This new law includes a provision that imposes a transition tax on foreign earnings whether or not such earnings are repatriated to the U.S. In light of this new tax, the Company is reviewing its prior position on the reinvestment of the earnings of foreign subsidiaries outside of the U.S. Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, the Company makes certain estimates and assumptions in (i) calculating its income tax expense, deferred tax assets and deferred tax liabilities, (ii) determining any valuation allowance recorded against deferred tax assets and (iii) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. The Company’s estimates and assumptions may differ significantly from tax benefits ultimately realized.
Foreign currency translation	Foreign currency translation The Euro has been determined to be the primary functional currency for the Company’s European operations, and local currencies have been determined to be the functional currencies for the Company’s Asia Pacific and Latin American operations. Foreign exchange gains and losses, which result from the process of remeasuring foreign currency transactions into the appropriate functional currency, are included in Other income (expense), net in the Company’s Consolidated Statements of Operations. The impact of changes in foreign currency exchange rates resulting from the translation of foreign currency financial statements into U.S. dollars for financial reporting purposes is included in other comprehensive income, which is a separate component of stockholders’ equity. Assets and liabilities are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at average rates for the period.
Customer and credit risk	Customers and credit risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, investments and trade receivables. The Company primarily places its cash, cash equivalents and investments with high-credit quality financial institutions that invest predominantly in U.S. government instruments, investment grade corporate bonds and certificates of deposit guaranteed by banks that are members of the Federal Deposit Insurance Corporation. Cash deposits are primarily in financial institutions in the U.S. and the United Kingdom. However, cash for monthly operating costs of international operations are deposited in banks outside the U.S. The Company performs credit evaluations to reduce credit risk and generally requires no collateral from its customers. Management estimates the allowance for uncollectible accounts based on its historical experience and credit evaluation. The Company’s standard credit terms are net 30 days in North America, net 30 to net 45 days in EMEA (Europe, Middle East and Africa) and Latin America, and range from net 30 to net 60 days in Asia Pacific (principally Australia, China, India, Japan, Singapore and South Korea).
Net income per common share	Net income per common share The Company computes basic net income per common share by dividing net income available to common stockholders by the weighted average number of common shares outstanding. Diluted net income per common share is computed by dividing net income by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. Potential common share equivalents consist of shares issuable upon the exercise of stock options or vesting of share-based awards. With respect to the Company’s 0.25% convertible senior notes due 2019 (the “convertible notes”), the Company has the option to pay cash or deliver, as the case may be, either cash, shares of its common stock or a combination of cash and shares of its common stock for the aggregate amount due upon conversion of the convertible notes. The Company’s intent is to settle the principal amount of the convertible notes in cash upon conversion. As a result, upon conversion of the convertible notes, only the amounts payable in excess of the principal amounts of the notes are considered in diluted earnings per share under the treasury stock method.
Segment reporting	Segment reporting The Company is organized primarily on the basis of three geographic business units: the Americas (U.S., Canada and Latin America), EMEA and Asia Pacific. These business units are aggregated into one reportable segment due to the similarity in nature of products and services provided, financial performance economic characteristics (e.g., revenue growth and gross margin), methods of production and distribution and customer classes (e.g., cloud service providers, distributors, resellers and enterprise). The Company has offices in more than 95 locations around the world. The Company manages its international business on an Americas-wide, EMEA-wide and Asia Pacific-wide basis.
Recent accounting pronouncements	Recent accounting pronouncements Accounting pronouncements adopted In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). The FASB issued ASU 2017-09 to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when applying the guidance in Topic 718, to a change to the terms and conditions of a share-based payment award. The Company early adopted ASU 2017-09 as of the second quarter of its fiscal year ended February 28, 2018. The adoption of this update did not impact the Company’s Consolidated Financial Statements. In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) . The FASB issued ASU 2017-04 to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under this updated standard, an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity also should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if any. The FASB also eliminated the requirement for reporting units with a zero or negative carrying amount to first perform a qualitative assessment. The Company adopted ASU 2017-04 during the second quarter of its fiscal year ended February 28, 2018. The adoption of this update did not impact the Company’s Consolidated Financial Statements. In August 2016, the FASB issued Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The FASB issued ASU 2016-15 to decrease the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. The Company adopted ASU 2016-15 along with Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”) during the fourth quarter of its fiscal year ended February 28, 2018. The adoption of these updates did not significantly impact the Company’s Consolidated Financial Statements. Accounting pronouncements being evaluated In February 2018, the FASB issued Accounting Standards Update 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). The FASB issued ASU 2018-02 to give entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the enactment of the Tax Act to retained earnings. The guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2020, with early adoption permitted. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842) (“ASU 2016-02”). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations with respect to accounting for leases. Under ASU 2016-02, lessees will recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. This guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2020. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements. In January 2016, the FASB issued Accounting Standards Update 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The FASB issued ASU 2016-01 to require equity investments with readily determinable fair values to be measured at fair value with changes in fair value recognized in net income. Equity investments that do not have readily determinable fair values are allowed to be remeasured upon the occurrence of an observable price change or upon identification of an impairment. This guidance is effective for the Company as of the first quarter of its fiscal year ending February 28, 2019. The Company is currently evaluating the impact that this updated standard will have on its consolidated financial statements, along with the Accounting Standards Update 2018-03, Technical Corrections and Improvements to Financial Instruments Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2018-03”), which was issued in February 2018, and Accounting Standards Update 2018-04, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (“ASU 2018-04”), which was issued in March 2018. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers , now commonly referred to as Accounting Standards Codification Topic 606 (“ASC 606”). The FASB issued ASC 606 to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance. This guidance is effective for the Company beginning the first quarter of its fiscal year ending February 28, 2019. The standard must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company has substantially completed its assessment of the potential impact that the implementation of this updated standard will have on its consolidated financial statements. With respect to the Company’s software subscription offerings, which accounted for 88% , 89% , and 88% of the Company’s total revenue for the fiscal years ended February 28, 2018 , February 28, 2017 and February 29, 2016 , respectively, the Company provides value to its customers through continuous aggregation, integration, testing, certification, maintenance, enhancement and support of the open source technologies that it distributes. The Company currently recognizes subscription revenue ratably over the subscription period. Under the updated standard, these subscription attributes represent a series of performance obligations that are delivered over time, primarily on a stand-ready basis (for example, attributes such as updates, upgrades and support are made available to subscribers). As a result, the Company believes that its subscription revenue meets the criteria for revenue recognition over time and will continue to be recognized ratably under the updated standard. The Company also offers professional consulting and training services that are designed to help customers derive additional value from Red Hat technologies. Under the updated guidance, revenue from professional consulting and training services that were previously sold on a standalone basis will continue to be recognized over time as the Company satisfies its performance obligations by delivering and transferring such services to the customer. With respect to customer contracts with multiple elements (such as software subscriptions and professional consulting and training services), under the current standard the Company allocates total contract revenue to each element’s relative fair value when the Company can demonstrate sufficient VSOE of the fair value of at least those elements that are undelivered. For multiple-element contracts in which one or more of the undelivered elements lacks VSOE, the Company defers recognition of any revenue until the elements lacking VSOE have been delivered. However, under the updated standard, the Company will be required to allocate total contract revenue to each element (referred to as a distinct performance obligation under the updated standard) based on either an established or estimated standalone selling price. The Company would then recognize the allocated revenue as each element (performance obligation) is delivered. Because the Company has historically established VSOE for most of its offerings and as a result has not been required to defer a significant amount of revenue due to insufficient VSOE, the Company does not anticipate the new standard’s requirement to establish or estimate a standalone selling price, rather than defer revenues in the absence of VSOE, to have a significant impact on the Company’s financial statements. The Company currently defers and amortizes commissions over a period that approximates the subscription period. Under the new standard, the Company does not anticipate a change to this approach. The Company is reviewing whether additional direct costs to obtain customer contracts will be deferred and amortized. The Company is continuing to assess all potential impacts that ASC 606 will have on its consolidated financial statements. The assessment includes, for example, any potential changes to and investments in the Company’s policies, processes, systems and internal controls over financial reporting that may be required to comply with the new guidance related to variable consideration, contract modifications, allocation of discounts and expanded disclosures. The Company is implementing new revenue recognition software to enable accounting assessments under the new standard. The Company will adopt ASC 606 using the full retrospective method.
