Description of Business and Summary of Significant Accounting Policies | Description of Business and Summary of Significant Accounting Policies Description of Business FireEye, Inc., with principal executive offices located in Milpitas, California, was incorporated as NetForts, Inc. on February 18, 2004, under the laws of the State of Delaware, and changed its name to FireEye, Inc. on September 7, 2005. FireEye, Inc. and its wholly owned subsidiaries (collectively, the “Company”, “we”, “us” or “our”) provide comprehensive intelligence-based cybersecurity solutions that allow organizations to prepare for, prevent, investigate, respond to and remediate cyber attacks. Our portfolio of cyber security products and services is designed to minimize the risk of costly cyber security breaches by detecting and preventing advanced, targeted and other evasive attacks, as well as enabling more efficient management of security operations, including alert management, investigation and response when a breach occurs. We accomplish this through the integration of our core competitive advantages in products and services that adapt to changes in the threat environment through a cycle of intelligence-driven innovation. Our core competitive advantages include: • Our technologies, including our machine-learning, behavioral-based, and rules-based threat detection, analysis and correlation technologies, combined with our proprietary Multi-vector Virtual Execution ("MVX") engine; • Our intelligence on threats and threat actors, based on the continuous flow of machine-, attacker- and victim-based attack data from our global network of threat sensors and virtual machines, as well as intelligence gathered by our security analysts, consultants and incident responders; and • Our accumulated security expertise derived from responding to thousands of significant breaches over the past decade. Our threat detection and prevention products encompass appliance-based, virtual and cloud solutions for web security, email security and endpoint security. These products are complemented by our cloud-based threat intelligence, security analytics and security automation and orchestration technologies, as well as our managed security services, cybersecurity consulting and incident response offerings. In combination, our solutions and services enable a proactive approach to cybersecurity that extends across the threat management lifecycle to minimize the risk of costly cybersecurity breaches. We have organized our cybersecurity solutions in a hub and spokes model designed to integrate machine-generated threat data from our detection and prevention products with our analytics, response and orchestration technologies delivered through our Helix cybersecurity operations platform. Helix is designed to enable more efficient security operations by correlating security and event data across an organization’s environment to determine which threats present the greatest risk, automating repetitive security processes, and providing tools and workflows to investigate and respond to attacks. The Helix cloud-based interface presents a unified view of an organization’s attack surface, including on-premise and cloud environments, and provides the contextual threat intelligence and threat management tools to enable a rapid response. In the three months ended June 30, 2018, we issued $600 million aggregate principal amount of 0.875% Convertible Senior Notes due 2024 (the "2024 Notes"), in a private placement to qualified institutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). We recognized total net proceeds after the initial purchasers' discount and issuance costs of $584.4 million . In connection with the issuance of the 2024 Notes, we also entered into capped call transactions (the "Capped Calls") with certain parties affiliated with the initial purchasers of the 2024 Notes. We paid approximately $65.2 million for the Capped Calls, which have an initial strike price of $23.17 per share, which corresponds to the initial conversion price of the 2024 Notes. The Capped Calls have an initial cap price of $34.32 per share subject to certain adjustments as set forth in the confirmations for the Capped Calls. In May 2018, in a separate transaction, we repurchased $340.2 million aggregate principal of existing 1.000% Convertible Senior Notes due 2035 (the "Series A Notes"). We used $330.4 million of the net proceeds from the 2024 Notes offering to repurchase such portion of the Series A Notes. In January 2018, we completed the acquisition of privately-held X15 Software, Inc. ("X15"), a data management company. As consideration for the acquisition, we paid cash consideration of $5.3 million and issued 1,016,334 shares of our common stock with an estimated fair value of $15.4 million . In October 2017, we acquired Clean Communications Limited (d/b/a The Email Laundry) ("The Email Laundry"), a privately-held email security company. We paid cash consideration of $4.3 million and issued 259,425 shares of our common stock with an estimated fair value of $4.4 million . The majority of our products, subscriptions and services are sold to end-customers through distributors, resellers, and strategic partners, with a lesser percentage of sales directly to our end-customers. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of FireEye, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany balances and transactions have been eliminated in consolidation. The Company adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606"), effective January 1, 2018 using the full retrospective method. Upon adoption, we recognized an increase of $125.8 million in accumulated deficit on January 1, 2016 and all prior period amounts impacted by the adoption have been updated. Amounts and disclosures set forth in this Annual Report on Form 10-K comply with ASC 606. Use of Estimates The preparation of consolidated financial statements in conformity with 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 date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such management estimates include, but are not limited to, determining the nature and timing of satisfaction of performance obligations, useful life of our security appliances that are dependent on intelligence and assessing the material rights associated with it, determining the standalone selling price ("SSP") of performance obligations, subscriptions and services, commissions expense including the period of benefit of customer acquisition cost, bonus expense, future taxable income, contract manufacturer liabilities, litigation and settlement costs and other loss contingencies, fair value of our equity awards, achievement of targets for performance stock units, fair value of the liability and equity components of the Convertible Senior Notes and the purchase price allocation of acquired businesses. We base our estimates on historical experience and on assumptions that we believe are reasonable. Changes in facts or circumstances may cause us to change our assumptions and estimates in future periods, and it is possible that actual results could differ from current or revised future estimates. Concentrations Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. We maintain a substantial portion of our cash and cash equivalents in money market funds invested in U.S. Treasury related obligations. Management believes that these financial institutions are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. Our short-term investments primarily consist of notes and bonds issued by corporate institutions and U.S. Government agencies. All of our investments are highly-rated by credit rating agencies and are issued by organizations with reputable credit, and therefore bear minimal credit risk. Our accounts receivables are primarily derived from a diverse set of customers across various geographical locations. We perform ongoing credit evaluations of our customers and generally do not require collateral on accounts receivable. We maintain an allowance for doubtful accounts for estimated potential credit losses. See Note 16 for information on major customers. We rely primarily on a single contract manufacturer to assemble our products. In some cases we rely on sole suppliers for a certain number of our components. Foreign Currency Translation and Transactions The functional currency of our foreign subsidiaries is the U.S. dollar. We translate all monetary assets and liabilities denominated in foreign currencies into U.S. dollars using the exchange rates in effect at the balance sheet dates and other assets and liabilities using historical exchange rates. Foreign currency denominated revenue and expenses have been re-measured using the average exchange rates in effect during each period. Foreign currency translation and transaction gains and losses have been included in other income (expense) and have not been significant for the years ended December 31, 2018 , 2017 and 2016 . For the years ended December 31, 2018 , 2017 and 2016 , we recognized a loss of $1.5 million , a gain of $1.8 million and a loss of $1.5 million , respectively. Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. We determine the appropriate classification of our investments at the time of purchase, and evaluate such designation at each balance sheet date. Short-term Investments We classify our investments in debt and equity securities as available-for-sale and record these investments at fair value. Investments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on the nature of the investments, their maturities, and their availability for use in current operations. Unrealized gains and losses are reported as a component of other comprehensive loss. Realized gains and losses are determined based on the specific identification method, and are reflected in our Consolidated Statements of Operations. We regularly review our investment portfolio to identify and evaluate investments that have indicators of possible impairment. Factors considered in determining whether a loss is other-than-temporary include, but are not limited to: the length of time and extent a security’s fair value has been below its cost, the financial condition and near-term prospects of the investee, the credit quality of the security’s issuer, likelihood of recovery and our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in value. For our debt instruments, we also evaluate whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its cost basis. Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, credit quality of debt instrument issuers, the duration and extent to which the fair value is less than cost and whether we have plans to sell the security, or it is more likely than not that we will be required to sell the security, before recovery. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense) and a new cost basis in the investment is established. Fair Value of Financial Instruments We define fair value as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities due to their short-term nature. Inventories Inventories are stated at the lower of cost or net realizable value. Provisions have been made to reduce all slow-moving, obsolete or unusable inventories to their net realizable values. We purchase completed units from contract manufacturers and substantially all of our inventories are finished goods held for use as service replacements. As of December 31, 2018 and 2017 , the reserves for excess and obsolete inventories were $5.2 million and $4.7 million , respectively. Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally two to five years. The estimated useful lives of property and equipment are described below: Property and Equipment Useful Life Computer equipment and software 2 to 5 years Leasehold improvements Shorter of estimated useful life or remaining lease term Furniture and fixtures 5 years Machinery and equipment 2 to 5 years Demonstration Units Product demonstration units are included in prepaid expenses and other current assets on the consolidated balance sheets. Demonstration units are recorded at cost and are amortized over the estimated useful life from the date of transfer from inventory, generally 12 months. We generally do not resell units that have been used for demonstration purposes. Impairment of Long-Lived Assets We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. Through December 31, 2018 we have not written down any of our long-lived assets as a result of impairment. Business Combinations We have accounted for all of our acquisitions using the acquisition method. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired, based on their estimated fair values. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to identifiable intangible assets. Significant assumptions used in valuing certain identifiable intangible assets include, but are not limited to, expected long-term market growth, future expected operating expenses, costs of capital, and appropriate discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and, as a result, actual results may differ from estimates. Goodwill and Purchased Intangibles Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as one reporting unit and has selected December 1 as the date to perform its annual impairment test. In the valuation of its goodwill, the Company must make assumptions regarding estimated future cash flows to be derived from the Company. If these estimates or their related assumptions change in the future, the Company may be required to record impairment for these assets. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities represents the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There was no impairment of goodwill recorded for the years ended December 31, 2018 , 2017 or 2016 . Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. Purchased intangible assets with indefinite lives are assessed for potential impairment annually, or when events or circumstances indicate that their carrying amounts might be impaired. Warranties We generally provide a one -year warranty on hardware. We do not accrue for potential warranty claims as a component of cost of product revenue as all product warranty claims are satisfied under our support and maintenance contracts. Contract Manufacturer Liabilities We outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturers and payments to such manufacturers are a significant portion of our product cost of revenue. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturers to us and to our partners upon shipment. Our independent contract manufacturers assemble our products using design specifications, quality assurance programs, and standards that we establish, and they procure components and assemble our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, we may accrue for costs for contractual manufacturing commitments in excess of our forecasted demand, including costs for excess components or for carrying costs incurred by our contract manufacturers. To date, we have not accrued any significant costs associated with this exposure. Contract Balances Accounts Receivable Trade accounts receivable are recorded at the billable amount where we have the unconditional right to bill, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each customer's expected ability to pay and collection history, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. Deferred Revenue (Contract Liabilities) and Contract Assets Deferred revenue consists of amounts that have been invoiced and for which we have the right to bill, but have not been recognized as revenue because the related goods or services have not been transferred. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current. Our contract assets consist of assets typically resulting when revenue recognized exceeds the amount billed or billable to the customer due to allocation of transaction price, and such amounts have been included in prepaid expenses and other current assets. Our contract assets were immaterial as of December 31, 2018 and December 31, 2017 . In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period. Assets Recognized from Costs to Obtain a Contract with a Customer Deferred Commissions Our customer acquisition costs are primarily related to sales commissions and related payroll taxes earned by our sales force and such costs are considered incremental costs to obtain a contract. Sales commissions for initial contracts are deferred and then amortized taking into consideration the pattern of transfer to which the asset relates and may include expected renewal periods where renewal commissions are not commensurate with the initial commissions period. We typically recognize the initial commissions over the longer of the customer relationship (generally estimated to be four years) or over the same period as the initial revenue arrangement to which these costs relate. Renewal commissions not commensurate with the initial commissions paid are generally amortized over the renewal period. Deferred commissions that will amortize within the succeeding twelve month period are classified as current, and included in prepaid expenses and other current assets on the Consolidated Balance Sheets. The remaining balance is classified as non-current, and included in deposits and other long-term assets. As of December 31, 2018 and December 31, 2017 , the amount of deferred commissions included in prepaid expenses and other current assets was $50.1 million and $43.8 million , respectively. The amount of deferred commissions included in deposits and other long-term assets as of December 31, 2018 and December 31, 2017 was $50.5 million and $43.0 million , respectively. Deferred Costs of Revenue Deferred costs of revenue consists of appliance related direct and incremental costs that are capitalized and will be amortized on a systematic basis that is consistent with the pattern of transfer to which the asset relates. Deferred costs of revenue that will be realized within the succeeding twelve month period are classified as current, and included in prepaid expenses and other current assets on the Consolidated Balance Sheets. The remaining balance is classified as non-current, and included in deposits and other long-term assets. As of December 31, 2018 and December 31, 2017 , the amount of deferred costs of revenue classified as current and included in prepaid expenses and other current assets was $17.0 million and $18.4 million , respectively. The amount of deferred costs of revenue classified as non-current and included in deposits and other long-term assets as of December 31, 2018 and December 31, 2017 was $20.3 million and $19.7 million , respectively. Revenue Recognition Revenue from Contracts with Customers Revenue is recognized when all of the following criteria are met: • Identification of the contract, or contracts, with a customer - A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and the parties are committed to perform, and (iii) we determine that collection of substantially all consideration to which it will be entitled in exchange for goods or services that will be transferred is probable based on the customer’s intent and ability to pay the promised consideration. • Identification of the performance obligations in the contract - Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods or services, we apply judgment to determine whether promised goods or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met the promised goods or services are accounted for as a combined performance obligation. • Determination of the transaction price - The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods or services to the customer adjusted for estimated variable consideration, if any. We typically estimate the transaction price impact of discounts offered to the customers for early payments on receivables or rebates based on channel partner sales achievements. Constraints are applied when estimating variable considerations based on historical experience where applicable. • Allocation of the transaction price to the performance obligations in the contract - If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative SSP basis. Determination of SSP requires judgment. We determine standalone selling price taking into account available information such as historical selling prices of the performance obligation, geographic location, overall strategic pricing objective, market conditions and internally approved pricing guidelines related to the performance obligations. • Recognition of revenue when, or as, we satisfy performance obligation - We satisfy performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at or over the time the related performance obligation is satisfied by transferring a promised good or service to a customer. Nature of Products and Services We generate revenue from the sales of physical and virtual security appliances (products), subscriptions, support and maintenance and professional services, primarily through our indirect relationships with our partners or direct relationships with end customers through our direct sales force. We account for our performance obligations in accordance with ASC 606, and all related interpretations. Our security appliance deliverables include proprietary operating system software, which together with regular security intelligence updates and support and maintenance, deliver the essential functionality of our appliance-based security products. We combine intelligence dependent appliances and software licenses with the related intelligence subscription and support as a single performance obligation. As a result, we recognize revenue for this single performance obligation ratably over the contractual term. Contracts containing this single performance obligation typically contain a material right of renewal option. For contracts that contain a material right of renewal option, the allocated value of the performance obligation is recognized ratably over the period between the end of the initial contractual term and the end of the estimated useful life of the related appliance and license. Revenue from subscriptions to our cloud-based services, which allow customers to use our hosted security software over a contracted period without taking possession of the software and managed services where we provide managed detection and response services for customers, are recognized over the contractual term. We also have a small portion of our revenue from appliances and software that are not dependent on regular threat intelligence updates. Revenue from these appliances and the associated software is therefore recognized when ownership is transferred to our customers, typically upon shipment. Professional services, which include incident response, compromise assessments, and other security consulting services are offered on a time-and-materials basis or through fixed fee arrangements, and we recognize the associated revenue as the services are delivered. Advertising Costs Advertising costs, which are expensed and included in sales and marketing expense when incurred, were $3.4 million , $2.6 million and $3.6 million during the years ended December 31, 2018 , 2017 and 2016 , respectively. Software Development Costs The costs to develop internal-use software are subject to capitalization and begin amortizing once the software is substantially ready for use. These costs are included in property and equipment and are generally amortized over 3 years. All other software development costs are expensed as incurred and included in research and development expense on the Consolidated Statements of Operations. Stock-Based Compensation Compensation expense related to stock-based transactions, including employee and non-employee director awards and our 2013 Employee Stock Purchase Plan (the "ESPP"), is measured and recognized in the financial statements based on fair value. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and a single option award approach. This model requires that at the date of grant we determine the fair value of the underlying common stock, the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The fair value of restricted stock awards and restricted stock units is based on the closing market price of our common stock on the date of grant. The stock-based compensation expense is recognized using a straight-line basis over the requisite service period of the entire awards, which is generally four years . Performance-based awards are subject to performance conditions. We recognize compensation expense over the requisite service period of each vesting tranche, when it becomes probable that the performance criteria set by our Board of Directors will be achieved. Beginning January 1, 2016 with the adoption of ASU 2016-09, we elected to recognize forfeitures as they occur, and no longer estimate a forfeiture rate when calculating the stock-based compensation for our equity awards. We account for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option-pricing model. The fair value of stock options granted to non-employees is remeasured as the stock options vest, and the resulting change in value, if any, is recognized in the statement of operations during the period the related services are rendered. Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the e |

Fair Value Measurements | Fair Value Measurements The accounting guidance for fair value measurements provides a framework for measuring fair value on either a recurring or nonrecurring basis, whereby the inputs used in our valuation techniques are assigned a hierarchical level. The following are the three levels of inputs to measure fair value: • Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Inputs that reflect quoted prices for identical assets or liabilities in less active markets; quoted prices for similar assets or liabilities in active markets; benchmark yields, reported trades, broker/dealer quotes, inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3: Unobservable inputs that reflect our own assumptions incorporated in valuation techniques used to measure fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. We consider an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and consider an inactive market to be one in which there are infrequent or few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, our own or the counterparty’s non-performance risk is considered in measuring the fair values of assets. The following table presents our assets and liabilities measured at fair value on a recurring basis using the above input categories (in thousands): As of December 31, 2018 As of December 31, 2017 Description Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 25,748 $ — $ — $ 25,748 $ 208 $ — $ — $ 208 U.S. Treasuries — — — — 3,098 — — 3,098 Total cash equivalents $ 25,748 $ — $ — $ 25,748 $ 3,306 $ — $ — $ 3,306 Short-term investments: Commercial paper — — — — — 4,987 — 4,987 Corporate notes and bonds — 448,323 — 448,323 — 438,024 — 438,024 U.S. Treasuries — 112,700 — 112,700 — — — — U.S. Government agencies — 145,668 — 145,668 — 272,900 — 272,900 Total short-term investments $ — $ 706,691 $ — $ 706,691 $ — $ 715,911 $ — $ 715,911 Total assets measured at fair value $ 25,748 $ 706,691 $ — $ 732,439 $ 3,306 $ 715,911 $ — $ 719,217 Additionally, we have a restructuring liability related to certain real estate facilities which was calculated based on the present value of future lease payments, less estimated sublease income, discounted at a rate commensurate with our current cost of financing. This non-recurring fair value measurement is considered to be a Level 3 measurement due to the use of significant unobservable inputs. To the extent that actual sublease income or the timing of subleasing these facilities is different than initial estimates, we will adjust the restructuring liability in the period during which such information becomes known. See Note 6 Restructuring Charges for a reconciliation of this liability. We measure certain assets, including goodwill, intangible assets and our equity-method investment in a private company at fair value on a nonrecurring basis when there are identifiable events or changes in circumstances that may have a significant adverse impact on the fair value of these assets. No such events or changes occurred during the year ended December 31, 2018 . The estimated fair value of the Convertible Senior Notes as of December 31, 2018 was determined to be $1.1 billion |

Business Combinations | Business Combinations On October 20, 2017, we acquired all of the outstanding shares of The Email Laundry, a privately held email security company, which is expected to enhance our current email offerings. In connection with this acquisition, we paid cash consideration of $4.3 million and issued 259,425 shares of our common stock with an estimated fair value of $4.4 million , resulting in total purchase consideration of $8.7 million . The purchase price is subject to customary working capital and related adjustments. The purchase price was allocated to intangible assets of $2.7 million , goodwill of $6.4 million and tangible net liabilities of $0.3 million . The intangible assets are composed of technology and customer relationships, each with an estimated weighted average useful life of 3 years. The goodwill is primarily attributable to the know-how of the workforce and is not expected to be deductible for U.S. federal income tax purposes. The results of operations of The Email Laundry have been included in our consolidated statements of operations from the acquisition date. Pro forma financial information has not been presented for this acquisition as the impact to our consolidated financial statements was not material. On January 11, 2018, we acquired all outstanding shares of privately held X15, a data management company. We expect that the X15 technology will be incorporated into our platform and analytics capabilities going forward. In connection with this acquisition, we paid cash consideration of $5.3 million and issued 1,016,334 shares of our common stock with an estimated fair value of $15.4 million , resulting in total purchase consideration of $20.7 million . The purchase price was allocated to intangible assets of $6.1 million , goodwill of $15.1 million and net tangible liabilities of $0.5 million . The intangible asset relates to developed technology with an estimated weighted average useful life of 3 years. The goodwill is primarily attributable to the know-how of the workforce and is not expected to be deductible for U.S. federal income tax purposes. The results of operations of X15 have been included in our consolidated statements of operations from the acquisition date. Pro forma financial information has not been presented for this acquisition as the impact to our consolidated financial statements was not material.

Restructuring and Related Activities [Abstract] | |
Restructuring Charges | Restructuring Charges In addition to our previous restructuring activities which took place in 2014, our Board of Directors approved a restructuring plan and reduction in workforce in August 2016 designed to reduce operating expenses and align our expense structure with current growth expectations. This resulted in a 10% reduction in our workforce, the consolidation of certain real estate facilities and impairment of certain assets. The following table sets forth a summary of restructuring activities during the years ended December 31, 2018 and 2017 (in thousands): Severance and related costs Facilities costs Total costs Balance, December 31, 2016 $ 1,221 $ 2,246 $ 3,467 Provision for restructuring charges — — — Cash payments (752 ) (1,046 ) (1,798 ) Other adjustments (469 ) (265 ) (734 ) Balance, December 31, 2017 $ — 935 $ 935 Provision for restructuring charges — — — Cash payments — (175 ) (175 ) Other adjustments — 390 390 Balance, December 31, 2018 $ — $ 1,150 $ 1,150 Other adjustments of $0.4 million and negative $0.7 million for the year ended December 31, 2018 and 2017 primarily represented relief of unused benefits, changes in fair value and foreign currency fluctuations.

See Note 1 for impact of adoption. Remaining Performance Obligations Transaction price allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and non-cancelable contracts that will be invoiced and recognized as revenue in future periods ("backlog"). While deferred revenue is recorded on our balance sheet as a liability, backlog is not recorded in revenue, deferred revenue or elsewhere in our consolidated financial statements until we establish a contractual right to invoice, at which point it is recorded as revenue or deferred revenue as appropriate. As of December 31, 2018 , the aggregate amount of the transaction price allocated to remaining performance obligations was $934.8 million in deferred revenue and $26.9 million in backlog. We have used the practical expedient to not disclose backlog related to the comparative period under ASC 606. We expect that the amount of backlog relative to the total value of our contracts will change from year to year due to several factors, including the amount invoiced early in the contract term, the timing and duration of customer agreements, varying invoicing cycles of agreements and changes in customer financial circumstances. Accordingly, we believe that fluctuations in backlog are not always a reliable indicator of future revenues and we do not utilize backlog internally as a key management metric. We expect to recognize these remaining performance obligations as follows (in percentages): Total Less than 1 year 1-2 years 2-3 years More than 3 years Deferred revenue 100% 60% 25% 12% 3% Backlog 100% 37% 34% 21% 8% |

Debt Disclosure [Abstract] | |
Convertible Senior Notes | Convertible Senior Notes Convertible Senior Notes due 2024 On May 24, 2018, we issued $525.0 million aggregate principal amount of the 2024 Notes in a private placement to qualified institutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act. In addition, on June 5, 2018, we issued an additional $75.0 million aggregate principal amount of the 2024 Notes pursuant to the full exercise of the initial purchasers' option to purchase additional 2024 Notes, in a private placement exempt from the registration requirements of the Securities Act. The net proceeds from the offerings, after deducting the initial purchasers' discount of approximately $15.0 million and the issuance costs of approximately $0.6 million , were $584.4 million . We used (i) approximately $330.4 million of the net proceeds to repurchase approximately $340.2 million in aggregate principal amount outstanding of the Series A Notes in negotiated transactions with institutional investors and (ii) approximately $65.2 million of the net proceeds from the offering of the 2024 Notes to enter into the Capped Calls (as defined below). The 2024 Notes are unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 2024 Notes. They rank equally in right of payment with all of our existing and future liabilities that are not expressly subordinated to the 2024 Notes including the Series A Notes and the Series B Notes (as defined below); and effectively rank junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness. The 2024 Notes are structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The 2024 Notes do not contain any financial covenants and do not restrict us from paying dividends or issuing or repurchasing other securities. The 2024 Notes bear interest at 0.875% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning December 1, 2018. The 2024 Notes mature on June 1, 2024, unless earlier repurchased, redeemed or converted. The initial conversion rate of the 2024 Notes is 43.1667 shares of our common stock per $1,000 of principal amount of the 2024 Notes, which is equivalent to an initial conversion price of approximately $23.17 per share of common stock. The conversion rate of the 2024 Notes may be adjusted pursuant to the terms of the indenture governing the 2024 Notes upon the occurrence of certain specified events, but not for accrued and unpaid interest. Holders may convert the 2024 Notes at their option in multiples of $1,000 principal amount prior to the business day preceding March 1, 2024, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ended on September 30, 2018 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of the 2024 Notes on each applicable trading day; • during the five business day period after any five consecutive trading day period (the "measurement period") in which the trading price per $1,000 principal amount of the 2024 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes on each such trading day; • if we call any or all of the 2024 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the relevant redemption date; or • upon the occurrence of specified corporate events, as specified in each indenture governing the 2024 Notes. Regardless of the foregoing conditions, holders may convert their 2024 Notes at their option in multiples of $1,000 principal amount during the period from, and including, March 1, 2024 to the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the 2024 Notes can be settled in cash, shares of our common stock or any combination of cash and shares of common stock at our option. Holders may also require us to repurchase the 2024 Notes if we undergo a "fundamental change," as defined in each indenture governing the 2024 Notes, at a repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Additionally, we may redeem for cash all or any portion of the 2024 Notes on or after June 5, 2021, if the last reported sale price of our common stock has been at least 130% of the conversion price of the 2024 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. As of December 31, 2018 , none of the conditions permitting holders to convert their 2024 Notes had been satisfied and no shares of our common stock had been issued in connection with any conversions of the 2024 Notes. Based on the closing price of our common stock of $16.21 per share on December 31, 2018, the conversion value of the 2024 Notes was less than the principal amount of the 2024 Notes outstanding on a per 2024 Note basis. In accordance with accounting for debt with conversions and other options, we bifurcated the principal amount of the 2024 Notes into liability and equity components. The initial liability component of the 2024 Notes was valued at $458.3 million based on the contractual cash flows discounted at an appropriate comparable market non-convertible debt borrowing rate at the date of issuance of 5.5% with the equity component representing the residual amount of the proceeds of $141.7 million , which was recorded as a debt discount. Issuance costs were allocated pro rata based on the relative initial carrying amounts of the liability and equity components. As a result, transaction costs of $0.5 million and $0.1 million and initial purchasers' discount of $11.5 million and $3.5 million were attributable to the liability component and equity component of the 2024 Notes, respectively. The debt discount and the issuance costs allocated to the liability component are amortized as additional interest expense over the term of the 2024 Notes using the effective interest method as noted in the table below. The liability and equity components of the 2024 Notes consisted of the following (in thousands): As of December 31, 2018 2024 Notes Liability component: Principal $ 600,000 Less: 2024 Notes debt discounts and issuance costs, net of amortization (140,239 ) Net carrying amount $ 459,761 Equity component, net of issuance costs $ 138,064 The unamortized issuance costs as of December 31, 2018 will be amortized over a weighted-average remaining period of approximately 5.4 years. Interest expense for the year ended December 31, 2018 related to the 2024 Notes consisted of the following (dollars in thousands): Year Ended December 31, 2018 2024 Notes Coupon interest $ 3,145 Amortization of 2024 Notes debt discounts and issuance costs 13,420 Total interest expense recognized $ 16,565 Effective interest rate on the liability component 5.6 % In connection with the 2024 Notes offering, the Company entered into capped call transactions (the "Capped Calls") with certain counterparties affiliated with the initial purchasers of the 2024 Notes. The Capped Calls are expected to reduce potential dilution of earnings per share upon conversion of the 2024 Notes, and have an initial strike price of $23.17 per share, which corresponds to the initial conversion price of the 2024 Notes and which have a cap price of $34.32 per share. The Capped Calls do not meet the criteria for separate accounting as a derivative as they are indexed to our own stock and are accounted for as freestanding financial instruments. The premiums paid for the purchase of the Capped Calls in the amount of $65.2 million have been recorded as a reduction of the Company's additional paid-in capital in stockholder's equity in the accompanying Consolidated Financial Statements and fair values of the Capped Calls are not re-measured at each reporting period. Convertible Senior Notes due 2035 In June 2015, we issued $460.0 million principal amount of Series A Notes and $460.0 million principal amount of 1.625% Convertible Senior Notes due 2035 (the “Series B Notes” and together with the Series A Notes, the "2035 Notes", and the 2035 Notes, together with the 2024 Notes, the "Convertible Senior Notes"), including the full exercise of the initial purchasers' over-allotment option, in a private placement to qualified institutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act. The net proceeds after the initial purchasers' discount of $23.0 million and issuance costs of $0.5 million from the 2035 Notes were $896.5 million . The Series A Notes and Series B Notes bear interest at 1.000% per year and 1.625% per year, respectively, payable semiannually in arrears on June 1 and December 1 of each year, beginning December 1, 2015. The 2035 Notes mature on June 1, 2035, unless earlier repurchased, redeemed or converted. The 2035 Notes are unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the 2035 Notes. They rank equally in right of payment with all of our existing and future liabilities that are not expressly subordinated to the 2035 Notes and effectively rank junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness. They are structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The 2035 Notes do not contain any financial covenants and do not restrict us from paying dividends or issuing or repurchasing our other securities. The initial conversion rate on each series of 2035 Notes is 16.4572 shares of our common stock per $1,000 principal amount of 2035 Notes, which is equivalent to an initial conversion price of approximately $60.76 per share of common stock. The conversion rate of each series of 2035 Notes may be adjusted upon the occurrence of certain specified events, but not for accrued and unpaid interest. Holders may convert the 2035 Notes at their option in multiples of $1,000 principal amount prior to March 1, 2035, excluding the period from March 1, 2020 to June 1, 2020 in the case of the Series A Notes and March 1, 2022 to June 1, 2022 in the case of the Series B Notes, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ended on September 30, 2015 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2035 Notes of the relevant series on each applicable trading day; • during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Series A Notes or Series B Notes, as applicable, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes of the relevant series on each such trading day; • if we call any or all of the 2035 Notes of a series for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the relevant redemption date; or • upon the occurrence of specified corporate events, as specified in each indenture governing the 2035 Notes. Regardless of the foregoing conditions, holders may convert their 2035 Notes at their option in multiples of $1,000 principal amount at any time during the period from March 1, 2020 to June 1, 2020 in the case of the Series A Notes and during the period from March 1, 2022 to June 1, 2022 in the case of the Series B Notes, or after March 1, 2035 until maturity for either series of 2035 Notes. Upon conversion, the 2035 Notes can be settled in cash, shares of our common stock or any combination thereof at our option. We may be required by holders of the 2035 Notes to repurchase all or any portion of their 2035 Notes at 100% of the principal amount plus accrued and unpaid interest, on each of June 1, 2020, June 1, 2025 and June 1, 2030, in the case of the Series A Notes, and each of June 1, 2022, June 1, 2025 and June 1, 2030 in the case of the Series B Notes. Holders may also require us to repurchase the 2035 Notes if we undergo a "fundamental change," as defined in each indenture governing the 2035 Notes, at a purchase price equal to 100% of the principal amount, plus accrued and unpaid interest. Additionally, we may redeem for cash all or any portion of the Series B Notes on or after June 1, 2020 until June 1, 2022 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending not more than three trading days immediately preceding the date we provide notice of redemption. We also may redeem for cash all or any portion of the Series A Notes on or after June 1, 2020 until maturity and all or any portion of the Series B Notes on or after June 1, 2022 until maturity, regardless of the foregoing sale price condition. In accordance with accounting for debt with conversions and other options, we allocated the principal amount of the 2035 Notes into liability and equity components. We also allocated the total amount of initial purchasers' discount and transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the 2035 Notes. Transaction costs of $0.4 million and $0.1 million and initial purchasers' discount of $17.6 million and $5.4 million were attributable to the liability component and equity component of the 2035 Notes, respectively. Repurchase of a portion of the Series A Notes In May 2018, we used approximately $330.4 million of the net proceeds from the offering of the 2024 Notes to repurchase $340.2 million in aggregate principal amount of the Series A Notes. The repurchase was accounted for as a partial extinguishment of the Series A Notes. The consideration of approximately $330.4 million used to repurchase the Series A Notes was allocated between the liability and equity components of the amount extinguished by determining the fair value of the liability component immediately prior to the debt extinguishment and allocating that portion of the repurchase price to the liability component in the amount of $317.4 million . The residual of the repurchase price of $13.0 million was allocated to the equity component of the Series A Notes as a reduction of additional paid-in capital. The fair value of the debt extinguished was calculated using a discount rate of 4.5% , representing an estimate of the Company's borrowing rate at the date of repurchase with a remaining expected life of two years. As part of the repurchase, we wrote-off a portion of the unamortized debt issuance cost apportioned to the principal amount of Series A Notes repurchased. We also recorded a loss on partial extinguishment of the Series A Notes of $10.8 million in Other Expense, net, representing the difference between the consideration attributed to the liability component and the sum of the net carrying amount of the liability component and unamortized costs. As of December 31, 2018 , $119.8 million aggregate principal amount of the Series A Notes remains outstanding. The liability and equity components of the 2035 Notes consisted of the following (in thousands): As of December 31, 2018 2017 Series A Notes Series B Notes Series A Notes Series B Notes Liability component: Principal $ 119,828 $ 460,000 $ 460,000 $ 460,000 Less: 2035 Notes discounts and issuance costs, net of amortization (8,420 ) (68,592 ) (53,762 ) (86,660 ) Net carrying amount $ 111,408 $ 391,408 $ 406,238 $ 373,340 Equity component, net of issuance costs $ 79,555 $ 117,834 $ 92,567 $ 117,834 The unamortized discounts and issuance costs as of December 31, 2018 will be amortized over a weighted-average remaining period of approximately 3.2 years . Interest expense for the years ended December 31, 2018 , 2017 and 2016 related to the 2035 Notes consisted of the following (in thousands): Year Ended December 31, 2018 2017 2016 Series A Notes Series B Notes Series A Notes Series B Notes Series A Notes Series B Notes Coupon interest $ 2,537 $ 7,454 $ 4,600 $ 7,475 $ 4,600 $ 7,475 Amortization of 2035 Notes discounts and issuance costs 11,785 18,068 20,364 17,234 19,343 16,439 Total interest expense recognized $ 14,322 $ 25,522 $ 24,964 $ 24,709 $ 23,943 $ 23,914 Effective interest rate on the liability component 6.4 % 6.8 % 6.5 % 6.9 % 6.5 % 7.0 % Prepaid Forward Stock Purchase In connection with the issuance of the 2035 Notes, we also entered into privately negotiated prepaid forward transactions (the "Prepaid Forwards") with one of the initial purchasers of the 2035 Notes (the “Forward Counterparty”), pursuant to which we paid approximately $150.0 million . The amount of the prepaid is equivalent to approximately 3.3 million shares which are to be settled on or around June 1, 2020 and June 1, 2022, respectively, subject to any early settlement, in whole or in part, of each Prepaid Forward. The Prepaid Forwards are intended to facilitate privately negotiated derivative transactions by which investors in the 2035 Notes will be able to hedge their investment in the 2035 Notes. In the event we pay any cash dividends on our common stock, the Forward Counterparty will pay an equivalent amount back to us. The related shares were accounted for as a repurchase of common stock, and are presented as Treasury Stock in the consolidated balance sheets. The 3.3 million |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Leases We lease our facilities under various non-cancelable operating leases, which expire on various dates through the year ending December 31, 2027. Rent expense is recognized using the straight-line method over the term of the lease. Rent expense, net of sublease income, was $19.9 million , $19.5 million and $14.9 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The aggregate future non-cancelable minimum rental payments on our operating leases, as of December 31, 2018 , are as follows (in thousands): Years Ending December 31, Amount 2019 $ 15,530 2020 16,325 2021 14,976 2022 12,766 2023 11,926 2024 and thereafter 47,409 Total $ 118,932 Total future non-cancelable minimum rental payments have not been reduced by future minimum sublease rentals totaling $5.4 million . We are party to letters of credit totaling $3.8 million and $3.3 million as of December 31, 2018 and 2017 , respectively, issued primarily in support of operating leases for several of our facilities. These letters of credit are collateralized by a line with our bank. No amounts have been drawn against these letters of credit. Contract Manufacturer Commitments Our independent contract manufacturers procure components and assemble our products based on our forecasts. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and product marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate supply, we may issue forecasts and orders for components and products that are non-cancelable. As of December 31, 2018 and 2017 , we had non-cancelable open orders of $8.6 million and $11.6 million , respectively. We are required to record a liability for firm, non-cancelable and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of our future demand forecasts. As of December 31, 2018 , we have not incurred nor accrued any significant liabilities for such non-cancelable commitments. Purchase Obligations As of December 31, 2018 , we had approximately $13.0 million of non-cancelable firm purchase commitments primarily for purchases of software and services. In situations where we have received delivery of the goods or services as of December 31, 2018 under purchase orders outstanding as of the same date, such amounts are reflected in the consolidated balance sheet as accounts payable or accrued liabilities, and are excluded from the $13.0 million . Litigation From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or require us to enter into agreements which may not be available on terms favorable to us or at all. To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred, and the amount of such additional loss would be material, we will either disclose the estimated additional loss or state that such an estimate cannot be made. We do not currently believe that it is reasonably possible that additional losses in connection with litigation arising in the ordinary course of business would be material. Indemnification Under the indemnification provisions of our standard sales related contracts, we agree to defend our customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Our exposure under these indemnification provisions is generally limited to the total amount paid by our customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement.

Equity Award Plans | Equity Award Plans We have operated under our 2013 Equity Incentive Plan ("2013 Plan") since our initial public offering ("IPO") in September 2013. Our 2013 Plan provides for the issuance of restricted stock and the granting of options, stock appreciation rights, performance shares, performance units and restricted stock units to our employees, officers, directors and consultants. Our 2013 Plan provides for annual increases in the number of shares available for issuance on the first day of each fiscal year. Awards granted under the 2013 Plan vest over the periods determined by our Board of Directors or compensation committee of our Board of Directors, generally four years , and stock options granted under the 2013 Plan expire no more than ten years after the date of grant. In the case of an incentive stock option granted to an employee who at the time of grant owns stock representing more than 10% of the total combined voting power of all classes of stock, the exercise price shall be no less than 110% of the fair value per share on the date of grant, and the award shall expire five years from the date of grant. For options granted to any other employee, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. In the case of non-statutory stock options and options granted to consultants, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. Stock that is purchased prior to vesting is subject to our right of repurchase at any time following termination of the participant's service for so long as such stock remains unvested. Approximately 12.2 million shares and 11.7 million shares of our common stock were reserved for future grants as of December 31, 2018 and 2017 , respectively, under the 2013 Plan. As of January 1, 2019, an additional 9,980,579 shares of common stock became available for future grants under our 2013 Plan pursuant to provisions thereof that automatically increase the share reserve under such plan each year. Our ESPP allows eligible employees to acquire shares of our common stock at 85% of the lower of the fair market value of our common stock on the first trading day of each offering period or on the exercise date. Our ESPP provides for annual increases in the number of shares available for issuance on the first day of each fiscal year. An aggregate of 3,014,685 shares and 2,985,358 shares of common stock were available for future issuance as of December 31, 2018 and 2017 , respectively, under our ESPP. As of January 1, 2018, an additional 1,996,115 shares of common stock became available for future issuance under our ESPP pursuant to the provisions thereof that automatically increase the share reserve under such plan each year. From time to time, we also grant restricted common stock or restricted stock awards outside of our equity incentive plans to certain employees in connection with acquisitions.

During the years ended December 31, 2018 , 2017 and 2016 , we issued 1.3 million , 1.8 million and 3.0 million shares, respectively, of restricted common stock, restricted stock awards or restricted stock units to certain employees which vest upon the achievement of certain performance conditions in addition to a continued service relationship with the Company. Stock-Based Compensation We record stock-based compensation based on the fair value as determined on the date granted. We determine the fair value of stock options and shares of common stock to be issued under the ESPP using the Black-Scholes option-pricing model. The fair value of restricted stock units and restricted stock awards equals the market value of the underlying stock on the date of grant. We grant performance-based restricted stock units and restricted stock awards to certain employees which vest upon the achievement of certain performance conditions, subject to the employees’ continued service relationship with us. With respect to performance-based restricted stock units, we assess the probability of vesting at each reporting period and adjust our compensation cost based on this probability assessment. We recognize such compensation expense on a straight-line basis over the service provider’s requisite service period. We determined valuation assumptions as follows: Fair Value of Common Stock We use the listed stock price on the date of grant as the fair value of our common stock. Risk-Free Interest Rate We base the risk-free interest rate used in the Black-Scholes option-pricing model on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent expected term of the options for each option group. Expected Term The expected term represents the period that our stock-based awards are expected to be outstanding. We base the expected term assumption on our historical experience combined with estimates of post-vesting holding periods. Volatility We determine the price volatility factor based on the historical volatilities of our peer group as we do not have sufficient trading history for our common stock. Dividend Yield The expected dividend assumption is based on our current expectations about our anticipated dividend policy. The following table summarizes the assumptions used in the Black-Scholes option-pricing model to determine the fair value of our common shares under the ESPP: Year Ended December 31, 2018 2017 2016 Fair value of common stock $16.69 - $20.01 $14.14 - $15.65 $13.12 - $14.12 Risk-free interest rate 2.08% - 2.70% 1.05% - 1.62% 0.38% - 0.79% Expected term (in years) 0.5 - 1.0 0.5 - 1.0 0.5 - 1.0 Volatility 32% - 38% 29% - 52% 57% - 63% Dividend yield —% —% —% Stock-based compensation expense related to stock options, ESPP and restricted stock units and awards is included in the consolidated statements of operations as follows (in thousands): Year Ended December 31, 2018 2017 2016 Cost of product, subscription and support revenue $ 14,178 $ 18,249 $ 16,684 Cost of professional services revenue 14,184 14,407 15,219 Research and development 49,503 56,720 64,755 Sales and marketing 47,592 46,766 57,750 General and administrative 28,218 30,194 43,343 Restructuring — — 1,144 Total $ 153,675 $ 166,336 $ 198,895 As of December 31, 2018 , total compensation cost related to stock-based awards not yet recognized was $229.3 million , which is expected to be amortized on a straight-line basis over the weighted-average remaining vesting period of approximately 2.5 |

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act includes a provision to tax GILTI of foreign subsidiaries and a base erosion abuse tax measure that taxes certain payments between a U.S. corporation and its foreign subsidiaries. Under U.S. GAAP, we can make an accounting policy election to either treat taxes due on the GILTI inclusion as a current period expense or factor such amounts into our measurement of deferred taxes. We have elected the current period expense method. The SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) which provides for a measurement period of up to one year after the enactment date of the Tax Act to finalize the related income tax impacts. In accordance with SAB 118, we provided our best estimate of the impact of the Tax Act in the period ended December 31, 2017. We remeasured our existing net U.S. deferred tax assets using the enacted tax rate and other known significant changes to the tax code. This remeasurement resulted in a total decrease in these assets by $71.7 million which was fully offset by the decrease in valuation allowance. In addition, we recorded a $0.3 million tax benefit related to the release of valuation allowance on AMT credit carryovers because under the Tax Act, existing AMT credits are refundable from 2018 through 2021. As a result of cumulative overall foreign losses, we did not incur the one-time transition tax. As of December 31, 2018, we have completed the accounting for the Tax Act within the measurement period. Our current period adjustments related to the estimated items were immaterial. A valuation allowance is provided when it is more likely than not that the deferred tax asset will not be realized. The valuation allowance decreased by approximately $9.1 million during the year ended December 31, 2018 , primarily as a result of the additional net deferred tax liability adjusted under convertible debt and deferred revenue that is recorded during the year. As of December 31, 2018 , we had federal and state net operating loss carry forwards of approximately $513.7 million and $583.9 million , respectively, available to reduce future taxable income, if any. If not utilized, the federal net operating loss carry forwards will expire from the years ending December 31, 2028 through 2037 while state net operating loss carry forwards will expire from the years ending December 31, 2019 through 2037. As of December 31, 2018 , we also had federal and state research and development tax credit carry forwards of approximately $30.3 million and $18.1 million , respectively. If not utilized, the federal credit carry forwards will expire in various amounts from the years ended December 31, 2024 through 2038. The state credit will expire from the year ended December 31, 2037. Utilization of the net operating loss carry forwards and credits may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted the standard effective January 1, 2018 retrospectively. As a result, the table of deferred tax assets shown above includes deferred tax assets and liabilities as of December 31, 2017 that arose directly from the adoption of ASC 606, which is offset with additional valuation allowance. As of December 31, 2018 , we had $42.5 million of unrecognized tax benefits, of which if recognized, $1.8 million would affect our effective tax rate. We file income tax returns in U.S. federal, state and foreign jurisdictions. As we have net operating loss carry forwards for U.S. federal and state jurisdictions, the statute of limitations is open for all tax years. For foreign jurisdictions, the tax years open to examination include the years 2014 and forward. We recognize both interest and penalties associated with uncertain tax positions as a component of income tax expense. During the year ended December 31, 2018 we recognized interest and penalties of $151,000 . During the years ended December 31, 2017 and 2016 , we recognized a $36,000 increase and $31,000 decrease to interest and penalties, respectively. As of December 31, 2018 and 2017 , our total accrual for interest and penalties was $554,000 and $403,000 , respectively. As of December 31, 2018 , we believe it is reasonably possible that our unrecognized tax benefits will decrease by approximately $0.3 million in the next 12 months due to potential foreign tax return filing. A reconciliation of gross unrecognized tax benefits is as follows (in thousands): Year Ended December 31, 2018 2017 2016 Unrecognized tax benefits at the beginning of the period $ 39,387 $ 43,637 $ 31,902 Additions for tax positions related to the current year 2,651 10,780 12,435 Increases related to prior year tax positions 501 — 561 Decreases related to prior year tax positions — (14,955 ) (1,213 ) Decreases based on settlements with taxing authorities — — (48 ) Lapse of statute of limitations (49 ) (75 ) — Unrecognized tax benefits at the end of the period $ 42,490 $ 39,387 $ 43,637 As of December 31, 2018 , we have not made any tax provision for U.S. income taxes on approximately $36.5 million |

Earnings Per Share [Abstract] | |
Net Loss per Share | Net Loss per Share Basic net loss per share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share based awards and options. Diluted net income per common share is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options, conversion of the Convertible Senior Notes and unvested restricted common stock and stock units. As we had net losses for the years ended December 31, 2018 , 2017 and 2016 , all potential common shares were excluded as they were determined to be anti-dilutive. The following table sets forth the computation of net loss per common share (in thousands, except per share amounts): Year Ended December 31, 2018 2017* 2016* Numerator: Net loss $ (243,123 ) $ (285,184 ) $ (485,435 ) Denominator: Weighted average number of shares outstanding—basic and diluted 190,803 177,757 163,211 Net loss per share—basic and diluted $ (1.27 ) $ (1.60 ) $ (2.97 ) *Certain prior period amounts have been adjusted as a result of adoption of ASC 606.

Segment and Major Customers Information | Segment and Major Customers Information Disaggregation of revenue by geography We conduct business globally and are primarily managed on a geographic basis. Our Chief Executive Officer, who is our chief operating decision maker, reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We define our regions into United States ("U.S."), Europe, the Middle East, and Africa ("EMEA"), Asia Pacific and Japan ("APAC"), and all remaining geographies (primarily Latin America and Canada) included in Others. There are no segment managers who are held accountable for operations, operating results, and plans for levels, components, or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure. Revenue by geographic region based on the billing address is as follows (in thousands): Year Ended December 31, 2018 2017* 2016* US $ 523,150 $ 521,232 $ 490,802 EMEA 135,736 116,205 93,832 APAC 122,516 105,196 90,682 Other 49,548 37,015 30,679 Total revenue $ 830,950 $ 779,648 $ 705,995 *Certain prior period amounts have been adjusted as a result of adoption of ASC 606. We generate revenue from sales of our network, email and endpoint security solutions, network forensics appliances, security orchestration software, cloud threat intelligence and analytics subscriptions, managed security service and our professional services. We disaggregate our revenue into two main categories: (i) product, subscription, and support and (ii) professional services. Within the Product, subscription and support category, we provide supplemental data to distinguish between solutions that are deployed on-premise (or in hybrid on-premise/cloud configurations), and solutions and managed services that are delivered entirely through the cloud. Security solutions deployed on-premise (or in hybrid on-premise/cloud configurations) are included in the Product and related subscription and support sub-category, and solutions without an on-premise component are included in the Cloud subscription and managed services sub-category. Revenue in Product and related subscription and support sub-category consists primarily of revenue from sales of our network, email and endpoint security solutions that are deployed on the customer's premise, either as an integrated security appliance or in distributed hybrid on-premise/cloud configurations. Both deployment options are available on pre-configured appliance hardware or as virtual appliance software, and include FireEye intelligence-driven analysis ("IDA") and, Multi-vector Virtual Execution ("MVX") software, our Dynamic Threat Intelligence (DTI) cloud updates and support services. To complement our product, subscription and support solutions, we offer professional services, including incident response and other security consulting services, to our customers who have experienced a cyber security breach or desire assistance assessing the resilience of their information systems infrastructure. The majority our professional services are offered on a time and materials basis, through a fixed fee arrangement, or on a retainer basis. Revenue from professional services is recognized as services are delivered. Revenue from our Expertise-on-Demand micro-services and some pre-paid professional services is deferred, and revenue is recognized when services are delivered.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation and Consolidation | Basis of Presentation and ConsolidationThe consolidated financial statements include the accounts of FireEye, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany balances and transactions have been eliminated in consolidation. |
Use of Estimates | Use of EstimatesThe preparation of consolidated financial statements in conformity with 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 date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such management estimates include, but are not limited to, determining the nature and timing of satisfaction of performance obligations, useful life of our security appliances that are dependent on intelligence and assessing the material rights associated with it, determining the standalone selling price ("SSP") of performance obligations, subscriptions and services, commissions expense including the period of benefit of customer acquisition cost, bonus expense, future taxable income, contract manufacturer liabilities, litigation and settlement costs and other loss contingencies, fair value of our equity awards, achievement of targets for performance stock units, fair value of the liability and equity components of the Convertible Senior Notes and the purchase price allocation of acquired businesses. We base our estimates on historical experience and on assumptions that we believe are reasonable. Changes in facts or circumstances may cause us to change our assumptions and estimates in future periods, and it is possible that actual results could differ from current or revised future estimates. |
Concentrations | Concentrations Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. We maintain a substantial portion of our cash and cash equivalents in money market funds invested in U.S. Treasury related obligations. Management believes that these financial institutions are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. Our short-term investments primarily consist of notes and bonds issued by corporate institutions and U.S. Government agencies. All of our investments are highly-rated by credit rating agencies and are issued by organizations with reputable credit, and therefore bear minimal credit risk. Our accounts receivables are primarily derived from a diverse set of customers across various geographical locations. We perform ongoing credit evaluations of our customers and generally do not require collateral on accounts receivable. We maintain an allowance for doubtful accounts for estimated potential credit losses. See Note 16 for information on major customers. |
Foreign Currency Translation and Transactions | Foreign Currency Translation and Transactions The functional currency of our foreign subsidiaries is the U.S. dollar. We translate all monetary assets and liabilities denominated in foreign currencies into U.S. dollars using the exchange rates in effect at the balance sheet dates and other assets and liabilities using historical exchange rates. |
Cash and Cash Equivalents | Cash and Cash EquivalentsWe consider all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. We determine the appropriate classification of our investments at the time of purchase, and evaluate such designation at each balance sheet date. |
Short-term Investments | Short-term Investments We classify our investments in debt and equity securities as available-for-sale and record these investments at fair value. Investments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on the nature of the investments, their maturities, and their availability for use in current operations. Unrealized gains and losses are reported as a component of other comprehensive loss. Realized gains and losses are determined based on the specific identification method, and are reflected in our Consolidated Statements of Operations. We regularly review our investment portfolio to identify and evaluate investments that have indicators of possible impairment. Factors considered in determining whether a loss is other-than-temporary include, but are not limited to: the length of time and extent a security’s fair value has been below its cost, the financial condition and near-term prospects of the investee, the credit quality of the security’s issuer, likelihood of recovery and our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in value. For our debt instruments, we also evaluate whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its cost basis. |
Fair Value of Financial Instruments | Fair Value of Financial InstrumentsWe define fair value as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities due to their short-term nature. |
Inventories | InventoriesInventories are stated at the lower of cost or net realizable value. Provisions have been made to reduce all slow-moving, obsolete or unusable inventories to their net realizable values. We purchase completed units from contract manufacturers and substantially all of our inventories are finished goods held for use as service replacements. |
Property and Equipment | Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally two to five years. The estimated useful lives of property and equipment are described below: Property and Equipment Useful Life Computer equipment and software 2 to 5 years Leasehold improvements Shorter of estimated useful life or remaining lease term Furniture and fixtures 5 years Machinery and equipment 2 to 5 years |
Demonstration Units | Demonstration Units Product demonstration units are included in prepaid expenses and other current assets on the consolidated balance sheets. Demonstration units are recorded at cost and are amortized over the estimated useful life from the date of transfer from inventory, generally 12 |
Impairment of Long-Lived Assets | Impairment of Long-Lived AssetsWe evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. |
Business Combinations | Business Combinations We have accounted for all of our acquisitions using the acquisition method. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired, based on their estimated fair values. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. |
Goodwill and Purchased Intangibles | Goodwill and Purchased Intangibles Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible and identifiable intangible assets acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as one reporting unit and has selected December 1 as the date to perform its annual impairment test. In the valuation of its goodwill, the Company must make assumptions regarding estimated future cash flows to be derived from the Company. If these estimates or their related assumptions change in the future, the Company may be required to record impairment for these assets. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities represents the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There was no impairment of goodwill recorded for the years ended December 31, 2018 , 2017 or 2016 . |

Revenue Recognition and Deferred Revenue | Contract Balances Accounts Receivable Trade accounts receivable are recorded at the billable amount where we have the unconditional right to bill, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each customer's expected ability to pay and collection history, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. Deferred Revenue (Contract Liabilities) and Contract Assets Deferred revenue consists of amounts that have been invoiced and for which we have the right to bill, but have not been recognized as revenue because the related goods or services have not been transferred. Deferred revenue that will be realized during the succeeding 12-month period is recorded as current, and the remaining deferred revenue is recorded as non-current. Our contract assets consist of assets typically resulting when revenue recognized exceeds the amount billed or billable to the customer due to allocation of transaction price, and such amounts have been included in prepaid expenses and other current assets. Our contract assets were immaterial as of December 31, 2018 and December 31, 2017 . In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with revenue recognized ratably over the contract period. Assets Recognized from Costs to Obtain a Contract with a Customer Deferred Commissions Our customer acquisition costs are primarily related to sales commissions and related payroll taxes earned by our sales force and such costs are considered incremental costs to obtain a contract. Sales commissions for initial contracts are deferred and then amortized taking into consideration the pattern of transfer to which the asset relates and may include expected renewal periods where renewal commissions are not commensurate with the initial commissions period. We typically recognize the initial commissions over the longer of the customer relationship (generally estimated to be four years) or over the same period as the initial revenue arrangement to which these costs relate. Renewal commissions not commensurate with the initial commissions paid are generally amortized over the renewal period. Deferred commissions that will amortize within the succeeding twelve month period are classified as current, and included in prepaid expenses and other current assets on the Consolidated Balance Sheets. The remaining balance is classified as non-current, and included in deposits and other long-term assets. As of December 31, 2018 and December 31, 2017 , the amount of deferred commissions included in prepaid expenses and other current assets was $50.1 million and $43.8 million , respectively. The amount of deferred commissions included in deposits and other long-term assets as of December 31, 2018 and December 31, 2017 was $50.5 million and $43.0 million , respectively. Deferred Costs of Revenue Revenue from Contracts with Customers Revenue is recognized when all of the following criteria are met: • Identification of the contract, or contracts, with a customer - A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and the parties are committed to perform, and (iii) we determine that collection of substantially all consideration to which it will be entitled in exchange for goods or services that will be transferred is probable based on the customer’s intent and ability to pay the promised consideration. • Identification of the performance obligations in the contract - Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods or services, we apply judgment to determine whether promised goods or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met the promised goods or services are accounted for as a combined performance obligation. • Determination of the transaction price - The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods or services to the customer adjusted for estimated variable consideration, if any. We typically estimate the transaction price impact of discounts offered to the customers for early payments on receivables or rebates based on channel partner sales achievements. Constraints are applied when estimating variable considerations based on historical experience where applicable. • Allocation of the transaction price to the performance obligations in the contract - If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative SSP basis. Determination of SSP requires judgment. We determine standalone selling price taking into account available information such as historical selling prices of the performance obligation, geographic location, overall strategic pricing objective, market conditions and internally approved pricing guidelines related to the performance obligations. • Recognition of revenue when, or as, we satisfy performance obligation - We satisfy performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at or over the time the related performance obligation is satisfied by transferring a promised good or service to a customer. Nature of Products and Services We generate revenue from the sales of physical and virtual security appliances (products), subscriptions, support and maintenance and professional services, primarily through our indirect relationships with our partners or direct relationships with end customers through our direct sales force. We account for our performance obligations in accordance with ASC 606, and all related interpretations. Our security appliance deliverables include proprietary operating system software, which together with regular security intelligence updates and support and maintenance, deliver the essential functionality of our appliance-based security products. We combine intelligence dependent appliances and software licenses with the related intelligence subscription and support as a single performance obligation. As a result, we recognize revenue for this single performance obligation ratably over the contractual term. Contracts containing this single performance obligation typically contain a material right of renewal option. For contracts that contain a material right of renewal option, the allocated value of the performance obligation is recognized ratably over the period between the end of the initial contractual term and the end of the estimated useful life of the related appliance and license. Revenue from subscriptions to our cloud-based services, which allow customers to use our hosted security software over a contracted period without taking possession of the software and managed services where we provide managed detection and response services for customers, are recognized over the contractual term. We also have a small portion of our revenue from appliances and software that are not dependent on regular threat intelligence updates. Revenue from these appliances and the associated software is therefore recognized when ownership is transferred to our customers, typically upon shipment. |
Contract Manufacturer Liabilities | Contract Manufacturer LiabilitiesWe outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturers and payments to such manufacturers are a significant portion of our product cost of revenue. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturers to us and to our partners upon shipment. Our independent contract manufacturers assemble our products using design specifications, quality assurance programs, and standards that we establish, and they procure components and assemble our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, we may accrue for costs for contractual manufacturing commitments in excess of our forecasted demand, including costs for excess components or for carrying costs incurred by our contract manufacturers. |
Advertising Costs | Advertising Costs Advertising costs, which are expensed and included in sales and marketing expense when incurred, were $3.4 million , $2.6 million and $3.6 million during the years ended December 31, 2018 , 2017 and 2016 |
Software Development Costs | Software Development Costs The costs to develop internal-use software are subject to capitalization and begin amortizing once the software is substantially ready for use. These costs are included in property and equipment and are generally amortized over 3 |
Stock-Based Compensation | Stock-Based Compensation Compensation expense related to stock-based transactions, including employee and non-employee director awards and our 2013 Employee Stock Purchase Plan (the "ESPP"), is measured and recognized in the financial statements based on fair value. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and a single option award approach. This model requires that at the date of grant we determine the fair value of the underlying common stock, the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The fair value of restricted stock awards and restricted stock units is based on the closing market price of our common stock on the date of grant. The stock-based compensation expense is recognized using a straight-line basis over the requisite service period of the entire awards, which is generally four years . Performance-based awards are subject to performance conditions. We recognize compensation expense over the requisite service period of each vesting tranche, when it becomes probable that the performance criteria set by our Board of Directors will be achieved. Beginning January 1, 2016 with the adoption of ASU 2016-09, we elected to recognize forfeitures as they occur, and no longer estimate a forfeiture rate when calculating the stock-based compensation for our equity awards. |
Income Taxes | Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded to reflect the future benefit of utilizing net operating losses and research and development credit carry forwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. We have elected to account for Global Intangible Low-Taxed Income (“GILTI”) under the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) as period costs when incurred. |
Net Loss Per Share Attributable to Common Stockholders | Net Loss Per Share Attributable to Common StockholdersWe calculate our basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Under the two-class method, in periods when we have net income, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period convertible preferred stock non-cumulative dividends, between common stock and the convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Our basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock are considered common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive. |
Convertible Senior Notes | Convertible Senior NotesWe allocated the principal amount of the Convertible Senior Notes between its liability and equity components. The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the conversion feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Convertible Senior Notes as a whole. The equity component is included in additional paid-in-capital in consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Convertible Senior Notes over the carrying amount of the liability component was recorded as a debt discount, and is being amortized to interest expense using the effective interest method through the first date holders have the right to require us to repurchase all or any portion of their Convertible Senior Notes; the first put date (see Note 9). We allocate the total amount of transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Senior Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the liability component of the Convertible Senior Notes, and are being amortized to interest expense using the effective interest method through the first put date. Transaction costs attributable to the equity component were netted with the equity component of the Convertible Senior Notes in additional paid-in capital. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard requires capitalization of the implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Further, the standard also requires the Company to expense the capitalized implementation costs of a hosting arrangement over the term of the hosting arrangement. This standard is effective for the Company beginning in the first quarter of 2020. Early adoption is permitted. The adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07 (Topic 718): Improvements to Non-employee Share-Based Payment Accounting ("Topic 718"). This standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. FASB clarified that Topic 718 does not apply to share-based payments used to effectively provide financing to the issuer or awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. This standard is effective for the Company beginning in the first quarter of 2019. Early adoption is permitted, but no earlier than an entity's adoption date of ASC 606. The adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018-02: Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income. This standard provides companies with an option to reclassify stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act of 2017 (the "Tax Act") from accumulated other comprehensive income to retained earnings. The guidance will be effective for the Company beginning in the first quarter of 2019 with early adoption permitted, and will be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the tax rate as a result of the Tax Act is recognized. We have not made a determination as to which alternative methods it will use when it adopts this standard, but does not expect the adoption of this ASU to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (i.e. Step 2 of the current guidance), instead measuring the impairment charge as the excess of the reporting unit's carrying amount over its fair value (i.e. Step 1 of the current guidance). The guidance is effective for the Company beginning in the first quarter of 2020, and should be applied prospectively. Early adoption is permitted for impairment testing dates after January 1, 2017. The adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes the impairment model for most financial assets (including accounts receivable) and certain other instruments by introducing a current expected credit loss ("CECL") model. The CECL model is a more forward-looking approach based on expected losses rather than incurred losses, requiring entities to estimate and record losses expected over the remaining contractual life of an asset. The guidance is effective for the Company beginning in the first quarter of 2020. Early adoption beginning January 1, 2019 is permitted. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This standard is intended to increase transparency and comparability among organizations by recognizing right-of-use assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This standard is effective for the Company beginning in the first quarter of 2019, with early adoption permitted. The standard provides for a modified retrospective transition approach to recognize and measure leases at the beginning of the earliest period presented. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements . The update provides an optional transition method that allows entities to apply the standard prospectively, versus recasting the prior periods presented. If elected, an entity would recognize a cumulative-effect adjustment to opening retained earnings in the period of adoption. We expect to adopt the new standard using this optional transition method. We have also elected the practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs which expired prior to January 1, 2019. We expect to recognize right-of-use assets of approximately $64.3 million to $72.6 million and lease liabilities of approximately $84.2 million to $92.5 million |
