Company

Company	12 Months Ended
	Feb. 28, 2015
Company	NOTE 1—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, middleware, storage and cloud 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, reliability, scalability, flexibility, stability 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.

Summary_of_Significant_Account

Summary of Significant Accounting Policies	12 Months Ended
	Feb. 28, 2015
Summary of Significant Accounting Policies	NOTE 2—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.
	Use of estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.
	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 which 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 life of the subscription. 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 errata, fixes, functionality enhancements to the technology and upgrades to new versions of the technologies, each on a when-and-if available basis, 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 cloud service providers, distributors, value added resellers, systems integrators and OEMs. 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 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.
	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-cancelable 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 period of the subscription term. 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-cancelable 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 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 tests goodwill for impairment annually. For the years ended February 28, 2015 and February 28, 2014, the Company applied its test for goodwill impairment as permitted by 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 for a company to perform the two-step goodwill impairment test as required in years prior to the adoption of ASU 2011-08.
	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 years ended February 28, 2015 and February 28, 2014. Consequently, the Company was not required to perform the remaining two-step quantitative goodwill impairment test.
	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.
	See NOTE 7—Other Assets, Net for further discussion of impairment losses on long-lived assets for the years ended February 28, 2015, February 28, 2014 and February 28, 2013.
	Cash and cash equivalents
	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.
	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 4—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 market 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. Upon realization, such amounts are reclassified from accumulated other comprehensive income to other income, net. Realized gains and losses and other than temporary impairments, if any, are reflected in the statements of operations as other income, 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 which 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 market value. See NOTE 18—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 releasing source code that it has developed on a weekly 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, 2015 and February 28, 2014, 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 equipment, computer software and leasehold improvements, which are recorded at cost and depreciated or amortized using the straight-line method over their estimated useful lives as follows: furniture and fixtures, seven years; computer equipment, three to four years; computer software, five years; leasehold improvements, over the lesser of the estimated remaining useful life of the asset or the remaining term of the lease. 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 at 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, net of estimated forfeitures. 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 13—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 $62.6 million, $53.4 million and $42.7 million for the years ended February 28, 2015, February 28, 2014 and February 28, 2013, 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 with the exception of those software development costs that may qualify for capitalization.
	Income taxes
	The Company accounts for income taxes using the liability method in which deferred tax assets or liabilities are recognized for the temporary differences between financial reporting and tax bases of the Company’s assets and liabilities and for tax carryforwards at enacted statutory tax rates in effect for the years in which the differences are expected to reverse.
	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 is the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. From time to time, however, the Company may remit a portion of these earnings to the extent it incurs no additional U.S. tax and it is otherwise feasible.
	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 11—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, with the exception of the Company’s operations in Mexico, where the functional currency is the U.S. dollar. 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, 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 which invest predominantly in U.S. government instruments, investment grade corporate bonds and certificates of deposit guaranteed by banks which 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 their historical experience and credit evaluation. The Company’s standard credit terms are net 30 days in North America, net 30 to 45 days in EMEA (Europe, Middle East and Africa) and Latin America, and range from net 30 to net 60 days in Asia Pacific.
	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 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 would be considered in diluted earnings per share under the treasury stock method. See NOTE 22—Convertible Notes to the Company’s Consolidated Financial Statements 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., Latin America and Canada), EMEA (Europe, Middle East and Africa) 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 85 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
In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). The FASB issued ASU 2015-03 to simplify the presentation of debt issuance costs related to a recognized debt liability to present the debt issuance costs as a direct deduction from the carrying value of the debt liability rather than showing the debt issuance costs as a deferred charge on the balance sheet. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and is effective for the Company as of the first quarter of the fiscal year ending February 28, 2017. The Company does not believe that this updated standard will have a material impact on the Company’s consolidated financial statements.
In June 2014, the FASB issued Accounting Standards Update 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). The FASB issued ASU 2014-12 to provide explicit guidance for share-based awards which allow for an employee to vest in an award upon achievement of a performance condition met after completion of a requisite service period regardless of whether the employee is rendering service on the date the performance target is achieved. ASU 2014-12 provides that the performance target should not be reflected in estimating the grant-date fair value of the award but rather compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and recognized prospectively over the remaining requisite service period. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and is effective for the Company as of the first quarter of the fiscal year ending February 28, 2017. The Company has not issued such share-based awards and does not believe that this updated standard will have a material impact on the Company’s consolidated financial statements.
In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The FASB issued ASU 2014-09 to clarify the principles for recognizing revenue and to develop a common revenue standard for generally accepted accounting principles (“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 currently effective for fiscal years and interim periods within those years beginning after December 15, 2016, which is effective for the Company as of the first quarter of the fiscal year ending February 28, 2018. The FASB has proposed, but has not yet ratified, a one year deferral of ASU 2014-09. The Company is evaluating the impact that the implementation of this standard will have on the Company’s consolidated financial statements.
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740)—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”), to eliminate diversity in practice of presenting unrecognized tax benefits as a liability or presenting unrecognized tax benefits as a reduction of a deferred tax asset for a net operating loss or tax credit carryforward in certain circumstances by requiring that an unrecognized tax benefit be presented in the financial statements as a reduction to deferred tax assets excluding certain exceptions. ASU 2013-11 became effective for the Company during the three months ended May 31, 2014. The updated standard did not have a material impact on the Company’s consolidated financial statements.
In March 2013, the FASB issued Accounting Standards Update No. 2013-05, Foreign Currency Matters (Topic 830)—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-05”), which requires a parent entity to release a related foreign entity’s cumulative translation adjustment into net income only if its sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 became effective for the Company during the three months ended May 31, 2014. The updated standard did not have a material impact on the Company’s consolidated financial statements.

Goodwill and other business combinations
The Company completed its annual goodwill impairment test in February 2015. No goodwill impairment was deemed to have occurred in fiscal 2015, 2014 or 2013. The following is a summary of goodwill for the years ended February 28, 2015, February 28, 2014 and February 28, 2013 (in thousands):
Balance at February 29, 2012		$	591,563
Acquisition of ManageIQ			83,074
Other acquisitions			17,462
Impact of foreign currency fluctuations and other adjustments			(1,188	)
Balance at February 28, 2013		$	690,911
Final purchase price allocation adjustment for ManageIQ			(3,164	)
Impact of foreign currency fluctuations			(317	)
Balance at February 28, 2014		$	687,430
Acquisition of Inktank			131,446
Acquisition of eNovance			60,849
Acquisition of FeedHenry			68,491
Impact of foreign currency fluctuations			(21,156	)
Balance at February 28, 2015		$	927,060
The excess of purchase price paid for FeedHenry, eNovance, Inktank, ManageIQ 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 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 enterprise solutions.

	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 market 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.

	As of February 28, 2015, the Company continues to maintain a valuation allowance against its deferred tax assets with respect to certain foreign and state net operating loss (“NOL”) and credit carryforwards. For the year ended February 28, 2015, the valuation allowance increased by $1.9 million primarily as a result of acquired foreign NOL carryfowards.
	As of February 28, 2015, the Company had U.S. federal NOL carryforwards of $43.5 million, foreign NOL carryforwards of $30.2 million and U.S. state NOL carryforwards of $75.2 million, of which $27.3 million consists of share-based compensation deductions in excess of the amounts expensed in the Company’s operating results. The resulting excess tax benefit will be recognized as an increase to additional paid in capital when realized. The NOL carryforwards expire in varying amounts beginning in the fiscal year ending February 29, 2016. As of February 28, 2015, the Company had U.S. federal research tax credit carryforwards of $7.4 million and state research tax credit carryforwards of $12.0 million, which expire in varying amounts beginning in the fiscal year ending February 29, 2016.
	Taxes computed at the statutory federal income tax rates are reconciled to the provision for income taxes for the years ended February 28, 2015, February 28, 2014 and February 28, 2013, respectively, as follows (in thousands):

-1	During the year ended February 28, 2013, the Company amended its state income tax returns for prior years, which resulted in a reduction of state tax, net of federal tax benefit, of $3.4 million.
-2	The Company qualifies for a tax holiday in Israel which began during the fiscal year ended February 28, 2011 and is scheduled to terminate as of the fiscal year ending February 29, 2020. The tax holiday provides for an exemption from income tax in the first two years, and for a reduced rate of taxation on income generated in Israel for the subsequent eight years. The financial impact of this holiday for the year ended February 28, 2015 was a $2.9 million reduction in the Company’s provision for income taxes, which increased the Company’s diluted earnings per share by approximately $0.02.
As of February 28, 2015, cumulative undistributed earnings of non-U.S. subsidiaries totaled $420.0 million. Determination of the deferred tax liability, if any, on these earnings reinvested indefinitely outside the U.S. is not practicable because of available foreign tax credits, continually changing variables and other factors. It is the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. From time to time, however, the Company may remit a portion of these earnings to the extent it does not incur additional U.S. tax and it is otherwise feasible. The Company has provided U.S. income taxes on the earnings of certain foreign subsidiaries that are not considered as permanently reinvested outside the U.S. The U.S. income tax on such earnings is completely offset by U.S. foreign tax credits. The Company has also provided U.S. income taxes on the earnings of certain foreign subsidiaries that are permanently reinvested outside the U.S. but are deemed distributed for U.S. federal income tax purposes. The U.S. income tax on such earnings is reduced or offset by available U.S. foreign tax credits.
Unrecognized tax benefits
The following table reconciles unrecognized tax benefits for the years ended February 28, 2015, February 28, 2014 and February 28, 2013 (in thousands):

Reductions related to changes in facts and circumstances			(229	)
Reductions related to lapse of the statute of limitations			(370	)
Balance at February 28, 2015		$	60,343
The Company’s unrecognized tax benefits as February 28, 2015 and February 28, 2014, which, if recognized, would affect the Company’s effective tax rate were $55.7 million and $49.7 million, respectively.
It is the Company’s policy to recognize interest and penalties related to uncertain tax positions as income tax expense. Accrued interest and penalties related to unrecognized tax benefits totaled $9.2 million and $6.0 million as of February 28, 2015 and February 28, 2014, respectively.
The results and timing of the resolution of tax audits is highly uncertain and the Company is unable to estimate the range of the possible changes to the balance of unrecognized tax benefits. However, the Company does not anticipate that within the next 12 months that the total amount of unrecognized tax benefits will significantly increase or decrease as a result of any such potential tax audit resolutions.
The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The following table summarizes the tax years in the Company’s major tax jurisdictions that remain subject to income tax examinations by tax authorities as of February 28, 2015. Due to NOL carryforwards, in some cases the tax years continue to remain subject to examination with respect to such NOLs:
Tax Jurisdiction		Years Subject to

-1	The U.S. Internal Revenue Service has completed its examination with respect to the Company’s fiscal year ended February 28, 2010 and proposed certain adjustments. The Company believes that it has adequately provided for any reasonably foreseeable outcomes that may result from the proposed adjustments but, depending on the ultimate outcome, the Company could be required to pay additional income taxes. The Company does not believe that such outcome would have a material effect on its consolidated financial condition or consolidated results of operations.
-2	The Company has been examined for income tax for years through February 28, 2011. A tax examination was concluded in fiscal 2012 with no significant adjustments resulting. However, the statute of limitations remains open for five years.
The Company is currently undergoing an income tax examination in India.

The RSA performance goal for fiscal year 2015 was met. Therefore, as of February 28, 2015 only the service condition remained, with 25% of such shares scheduled to vest vesting on July 16, 2015, one year from the date of grant, and the remainder vesting ratably on a quarterly basis over the course of the subsequent three-year period.
	The following summarizes share-based compensation expense recognized in the Company’s Consolidated Financial Statements for the years ended February 28, 2015, February 28, 2014 and February 28, 2013 (in thousands):

	Share-based compensation expense qualifying for capitalization was insignificant for each of the Company’s fiscal years ended February 28, 2015, February 28, 2014 and February 28, 2013. Accordingly, no share-based compensation expense was capitalized during these years.
	Estimated annual forfeitures—An estimated forfeiture rate of 10% per annum, which approximates the Company’s historical rate, was applied to options and service-based share awards. Awards are adjusted to actual forfeiture rates at vesting. The Company reassesses its estimated forfeiture rate annually or when new information, including actual forfeitures, indicate a change is appropriate.
	Stock options
	The 2004 Plan provides that the purchase price per share for each option shall not be less than the fair market value of the underlying share on the date of grant. Options granted under the 2004 Plan to date include contract terms of five years and generally vest 25% upon completion of one full year of service and 6.25% on the first day of each subsequent three-month period of service. The maximum contract term for an option granted under the 2004 Plan is seven years from the date of grant.

As of February 28, 2015, compensation cost related to unvested stock options not yet recognized in the Company’s Consolidated Financial Statements totaled $7.6 million. The weighted average period over which these unvested stock options are expected to be recognized is approximately 2.0 years.
The fair values of options granted or assumed during the years ended February 28, 2015, February 28, 2014 and February 28, 2013 were estimated on the date of grant or assumption using the Black-Scholes-Merton option-pricing model based on the following weighted average assumptions:
		Year ended			Year ended			Year ended
		February 28,			February 28,			February 28,
		2015			2014			2013
Expected dividend yield			—	%		—	%		—	%

Weighted average fair value of options granted or assumed during the period		$	48.45		$	12.64		$	15.16
-1	The expected volatility rates for options granted or assumed during the years ended February 28, 2015, February 28, 2014 and February 28, 2013 were estimated based on an approximate equal weighting of the historical volatility of the Company’s common stock over a period of approximately 3.27 years and the implied volatility of publicly traded options for the Company’s common stock.
-2	The expected term for options granted or assumed during the years ended February 28, 2015, February 28, 2014 and February 28, 2013 was determined based on the Company’s historical exercise data. The Company reassesses its estimate of expected term annually or when new information indicates a change is appropriate.
Service-based share awards
Service-based share awards include nonvested shares, nonvested share units and deferred share units granted under the 2004 Plan. Nonvested shares and share units generally vest, subject to continued service to the Company, (i) 25% on the first anniversary of the date of grant and 6.25% on the first day of each subsequent three-month period for nonvested shares and (ii) 25% each year over a four-year period beginning on the date of grant for nonvested share units. 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 fair value of service-based share awards recognized in the Company’s Consolidated Financial Statements for the years ended February 28, 2015, February 28, 2014 and February 28, 2013 was as follows (in thousands):

Performance-based share awards
Under the 2004 Plan, certain executive officers and senior management were awarded a target number of performance share units (“PSUs”). The PSU payouts are either based on (i) the Company’s financial performance (“performance condition”) or (ii) the performance of the Company’s common stock (“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 (or three separate performance segments for grants prior to fiscal 2014). 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 common stock over a performance period of approximately three years, PSU grantees may earn up to 200% of the target number of PSUs. The number of PSUs earned is determined based on a comparison of the performance of the Company’s total shareholder return (or share price for grants prior to fiscal 2014) relative to the performance of the total shareholder return (or share price for grants prior to fiscal 2014) of specified peer companies during the same performance period. 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 will pay out only if the Company’s total shareholder return increases by at least 50% within a three-year performance period beginning on August 6, 2014 (“TSR Hurdle PSUs”). If the performance goal is achieved during the performance period and the grantee’s business relationship with the Company has not ceased, 50% of the TSR Hurdle PSU’s shall vest upon achievement of the performance goal and the remaining 50% of the TSR Hurdle PSUs shall vest on the last day of the four-year service period beginning on August 6, 2014. If the performance goal is not met on or before the last day of the performance period, then all TSR Hurdle PSUs are forfeited.
The following table summarizes the activity for the Company’s PSUs for the years ended February 28, 2015, February 28, 2014 and February 28, 2013:

	Product indemnification
	The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party from losses arising in connection with the Company’s services or products, or from losses arising in connection with certain events defined within a particular contract, which may include litigation or claims relating to intellectual property infringement, certain losses arising from damage to property or injury to persons or other matters. 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 years ended February 28, 2015, February 28, 2014 and February 28, 2013 were in the aggregate immaterial.

	On April 15, 2013, the Company announced that its Board of Directors has authorized the repurchase of up to $300.0 million of Red Hat’s common stock from time to time on the open market or in privately negotiated transactions. The program commenced on April 16, 2013 and expired on March 31, 2015.
	As of February 28, 2015, the Company had repurchased 4,401,206 shares of its common stock for $220.0 million under this program. See NOTE 25—Subsequent Events for a discussion of the Company’s new share repurchase program.
	Accelerated share repurchase
	The Company used $375.0 million of the net proceeds from the issuance of the convertible notes discussed in NOTE 22—Convertible Notes to the Company’s Consolidated Financial Statements during the fiscal year ended February 28, 2015 to repurchase shares of its common stock under an accelerated share repurchase program (the “ASR Agreement”). On October 7, 2014, under the ASR Agreement, the Company paid $375.0 million to the ASR Agreement counterparty and received 5,312,555 shares of its common stock from the ASR Agreement counterparty, which represented 80% of the shares the Company would have repurchased assuming an average share price of $56.47 (the Company’s closing share price at October 1, 2014). The ASR Agreement was completed on February 27, 2015. On March 4, 2015, the ASR Agreement counterparty delivered 720,101 additional shares of the Company’s common stock to the Company in settlement of the ASR Agreement.
	The Company accounted for the ASR Agreement as two separate transactions: (i) the 5,312,555 shares of common stock initially delivered to the Company were accounted for as a treasury stock transaction with $300.0 million, or 80%, of the $375.0 million upfront payment being recorded in Treasury stock in the Company’s Consolidated Balance Sheet at February 28, 2015 and (ii) the unsettled portion of the ASR Agreement of $75.0 million was recorded in Additional paid-in capital on the Company’s Consolidated Balance Sheet as of February 28, 2015. The $75.0 million recorded in Additional paid-in capital will be reclassified to Treasury stock in the first quarter of fiscal year 2016 to reflect the March 4, 2015 settlement of the additional 720,101 shares of the Company’s common stock.

	The weighted average number of shares outstanding used in the computation of basic and diluted earnings per share for the fiscal year ended February 28, 2015 does not include the effect of common stock potentially issuable in accordance with the terms of the Company’s convertible notes and warrants. The effects of these potentially outstanding shares were not included in the calculation of diluted earnings per share because the effect would have been anti-dilutive.
	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 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 would be considered in diluted earnings per share under the treasury stock method. See NOTE 22—Convertible Notes to the Company’s Consolidated Financial Statements for detailed information on the convertible notes.

Convertible Notes	NOTE 22—Convertible Notes
	Convertible note offering
	On October 7, 2014, the Company completed its offering of $805.0 million aggregate principal amount of its 0.25% Convertible Senior Notes due 2019 (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.
	The Company used $148.0 million of the net proceeds from the offering of the convertible notes to pay the cost of the privately-negotiated convertible note hedge transactions described below. The Company received proceeds of $79.8 million from the sale of warrants pursuant to the warrant transactions described below.
	In addition, the Company used $375.0 million of the net proceeds from the offering of the convertible notes to repurchase shares of its common stock under an accelerated share repurchase program pursuant to an agreement that the Company entered into on October 1, 2014, as described in NOTE 17—Share Repurchase Programs to the Company’s Consolidated Financial Statements.
	The Company intends to use the remaining net proceeds from the offering for working capital and other general corporate purposes, which may include capital expenditures, potential acquisitions or strategic transactions.
	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 will be 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 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. The initial conversion price represents a premium of approximately 30% to the $56.47 per share closing price of the Company’s common stock on October 1, 2014. 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.
	Prior to April 1, 2019, the convertible notes will be convertible only upon the occurrence of certain circumstances, and will be convertible thereafter at any time until the close of business on the second scheduled trading day immediately preceding the maturity date of the convertible notes.
	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 convertible 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 carrying amount of the liability component was calculated by measuring the estimated fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the convertible notes as a whole. 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 amortized to interest expense over the term of the convertible notes using the effective interest method with an effective interest rate of 2.86% per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.
	As of February 28, 2015, the convertible notes consisted of the following (in thousands):
			February 28,
			2015
	Liability component
	Principal		$	805,000
	Less: debt discount			(89,598	)
	Net carrying amount		$	715,402
	Equity component (1)		$	96,890
	-1	Recorded in the Consolidated Balance Sheet in Additional paid-in capital.
	In accounting for the transaction costs related to the convertible note issuance, the Company allocated the total amount incurred of $15.2 million to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component totaled $13.4 million and are being amortized to interest expense over the term of the convertible notes using the effective interest method. The remaining $1.8 million of issuance costs have been allocated to the equity component and are included in Additional paid-in capital on the Company’s Consolidated Balance Sheet as of February 28, 2015. Additionally, the Company recorded a deferred tax asset of $0.7 million related to the $1.8 million equity component of transactional costs which are deductible for tax purposes.
	The following table includes total interest expense recognized related to the convertible notes for the fiscal year ended February 28, 2015 (in thousands):
			Year ended
			February 28,
			2015
	Coupon rate 0.25% per year, payable semiannually		$	805
	Amortization of convertible note issuance costs—liability component			935
	Accretion of debt discount			7,292
	Total interest expense related to convertible notes		$	9,032
	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, 2015
			Fair Value			Carrying Value
	Convertible notes		$	722,029		$	715,402
	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 (the “Option Counterparties”).
	The convertible note hedge transactions are expected to offset 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 same number of shares 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. However, subject to certain conditions, the Company may elect to settle all of the warrants in cash. The $101.65 strike price of the warrants represents a premium of approximately 80% over the $56.47 per share closing price of the Company’s common stock on October 1, 2014.
	The purchase of convertible note hedges and proceeds from issuance of warrants were recorded in stockholders’ equity and will continue to be classified as stockholders’ equity.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Feb. 28, 2015
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.
Use of estimates	Use of estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.
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 which 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 life of the subscription. 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 errata, fixes, functionality enhancements to the technology and upgrades to new versions of the technologies, each on a when-and-if available basis, 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 cloud service providers, distributors, value added resellers, systems integrators and OEMs. 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 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.
	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-cancelable 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 period of the subscription term. 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-cancelable 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 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 tests goodwill for impairment annually. For the years ended February 28, 2015 and February 28, 2014, the Company applied its test for goodwill impairment as permitted by 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 for a company to perform the two-step goodwill impairment test as required in years prior to the adoption of ASU 2011-08.
	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 years ended February 28, 2015 and February 28, 2014. Consequently, the Company was not required to perform the remaining two-step quantitative goodwill impairment test.
	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.
	See NOTE 7—Other Assets, Net for further discussion of impairment losses on long-lived assets for the years ended February 28, 2015, February 28, 2014 and February 28, 2013.
Cash and cash equivalents	Cash and cash equivalents
	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.
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. See NOTE 4—Accounts Receivable for further discussion on accounts receivable balances.
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 market 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. Upon realization, such amounts are reclassified from accumulated other comprehensive income to other income, net. Realized gains and losses and other than temporary impairments, if any, are reflected in the statements of operations as other income, 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 which 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 market value. See NOTE 18—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 releasing source code that it has developed on a weekly 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, 2015 and February 28, 2014, the Company had no internally developed capitalized software costs for products to be sold to third parties.
Property and equipment	Property and equipment
	Property and equipment is primarily comprised of furniture, computer equipment, computer software and leasehold improvements, which are recorded at cost and depreciated or amortized using the straight-line method over their estimated useful lives as follows: furniture and fixtures, seven years; computer equipment, three to four years; computer software, five years; leasehold improvements, over the lesser of the estimated remaining useful life of the asset or the remaining term of the lease. 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 at 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, net of estimated forfeitures. 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 13—Share-based Awards.
Sales 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.
	Advertising expense totaled $62.6 million, $53.4 million and $42.7 million for the years ended February 28, 2015, February 28, 2014 and February 28, 2013, respectively.
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 with the exception of those software development costs that may qualify for capitalization.
Income taxes	Income taxes
	The Company accounts for income taxes using the liability method in which deferred tax assets or liabilities are recognized for the temporary differences between financial reporting and tax bases of the Company’s assets and liabilities and for tax carryforwards at enacted statutory tax rates in effect for the years in which the differences are expected to reverse.
	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 is the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. From time to time, however, the Company may remit a portion of these earnings to the extent it incurs no additional U.S. tax and it is otherwise feasible.
	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 11—Income Taxes.
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, with the exception of the Company’s operations in Mexico, where the functional currency is the U.S. dollar. 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, 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	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 which invest predominantly in U.S. government instruments, investment grade corporate bonds and certificates of deposit guaranteed by banks which 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 their historical experience and credit evaluation. The Company’s standard credit terms are net 30 days in North America, net 30 to 45 days in EMEA (Europe, Middle East and Africa) and Latin America, and range from net 30 to net 60 days in Asia Pacific.
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 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 would be considered in diluted earnings per share under the treasury stock method. See NOTE 22—Convertible Notes to the Company’s Consolidated Financial Statements for detailed information on the convertible notes.
Segment reporting	Segment reporting
	The Company is organized primarily on the basis of three geographic business units: the Americas (U.S., Latin America and Canada), EMEA (Europe, Middle East and Africa) 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 85 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	Recent accounting pronouncements
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). The FASB issued ASU 2015-03 to simplify the presentation of debt issuance costs related to a recognized debt liability to present the debt issuance costs as a direct deduction from the carrying value of the debt liability rather than showing the debt issuance costs as a deferred charge on the balance sheet. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and is effective for the Company as of the first quarter of the fiscal year ending February 28, 2017. The Company does not believe that this updated standard will have a material impact on the Company’s consolidated financial statements.
	In June 2014, the FASB issued Accounting Standards Update 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). The FASB issued ASU 2014-12 to provide explicit guidance for share-based awards which allow for an employee to vest in an award upon achievement of a performance condition met after completion of a requisite service period regardless of whether the employee is rendering service on the date the performance target is achieved. ASU 2014-12 provides that the performance target should not be reflected in estimating the grant-date fair value of the award but rather compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and recognized prospectively over the remaining requisite service period. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015, and is effective for the Company as of the first quarter of the fiscal year ending February 28, 2017. The Company has not issued such share-based awards and does not believe that this updated standard will have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The FASB issued ASU 2014-09 to clarify the principles for recognizing revenue and to develop a common revenue standard for generally accepted accounting principles (“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 currently effective for fiscal years and interim periods within those years beginning after December 15, 2016, which is effective for the Company as of the first quarter of the fiscal year ending February 28, 2018. The FASB has proposed, but has not yet ratified, a one year deferral of ASU 2014-09. The Company is evaluating the impact that the implementation of this standard will have on the Company’s consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740)—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”), to eliminate diversity in practice of presenting unrecognized tax benefits as a liability or presenting unrecognized tax benefits as a reduction of a deferred tax asset for a net operating loss or tax credit carryforward in certain circumstances by requiring that an unrecognized tax benefit be presented in the financial statements as a reduction to deferred tax assets excluding certain exceptions. ASU 2013-11 became effective for the Company during the three months ended May 31, 2014. The updated standard did not have a material impact on the Company’s consolidated financial statements.
	In March 2013, the FASB issued Accounting Standards Update No. 2013-05, Foreign Currency Matters (Topic 830)—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-05”), which requires a parent entity to release a related foreign entity’s cumulative translation adjustment into net income only if its sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. ASU 2013-05 became effective for the Company during the three months ended May 31, 2014. The updated standard did not have a material impact on the Company’s consolidated financial statements.

[1]	During the year ended February 28, 2013, the Company amended its state income tax returns for prior years, which resulted in a reduction of state tax, net of federal tax benefit, of $3.4 million.
[2]	The Company qualifies for a tax holiday in Israel which began during the fiscal year ended February 28, 2011 and is scheduled to terminate as of the fiscal year ending February 29, 2020. The tax holiday provides for an exemption from income tax in the first two years, and for a reduced rate of taxation on income generated in Israel for the subsequent eight years. The financial impact of this holiday for the year ended February 28, 2015 was a $2.9 million reduction in the Company's provision for income taxes, which increased the Company's diluted earnings per share by approximately $0.02.

[1]	The U.S. Internal Revenue Service has completed its examination with respect to the Company's fiscal year ended February 28, 2010 and proposed certain adjustments.

The Company does not believe that such outcome would have a material effect on its consolidated financial condition or consolidated results of operations.
[2]	The Company has been examined for income tax for years through February 28, 2011. A tax examination was concluded in fiscal 2012 with no significant adjustments resulting. However, the statute of limitations remains open for five years.

[1]	Service-based shares granted during the year ended February 28, 2015 include 184,325 restricted shares awarded to certain executives that were subject to both a four-year service condition and the achievement of a specified dollar amount of revenue for fiscal year 2015 (the "RSA performance goal"). The RSA performance goal for fiscal year 2015 was met. Therefore, as of February 28, 2015 only the service condition remained, with 25% of such shares scheduled to vest vesting on July 16, 2015, one year from the date of grant, and the remainder vesting ratably on a quarterly basis over the course of the subsequent three-year period.
[2]	As part of the Company's acquisition of eNovance, a total of 529,057 restricted common shares were issued to certain shareholders of eNovance. These restricted shares are conditioned on continued employment with the Company. The shares effectively vest 25% per year and are being amortized on a straight-line basis to share-based compensation expense in the Company's Consolidated Statement of Operations.
