Accounting Policies [Abstract] | |||||||||||||||||
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies | ||||||||||||||||
Principles of Consolidation | |||||||||||||||||
The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and include our accounts and the accounts of our wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated upon consolidation. | |||||||||||||||||
Use of Estimates | |||||||||||||||||
The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |||||||||||||||||
Segments | |||||||||||||||||
We define the term “chief operating decision maker” to be our Chief Executive Officer. Our chief operating decision maker allocates resources and assesses financial performance based upon discrete financial information at the consolidated level. Accordingly, we have determined that we operate in a single reporting segment. | |||||||||||||||||
Foreign Currency Translation | |||||||||||||||||
The functional currencies for our foreign subsidiaries are primarily their local currencies. Assets and liabilities of the wholly-owned foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at each period end. Amounts classified in stockholders’ equity are translated at historical exchange rates. Revenues and expenses are translated at the average exchange rates during the period. The resulting translation adjustments are recorded in accumulated other comprehensive loss as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in interest and other income (expense), net within the consolidated statements of comprehensive loss. | |||||||||||||||||
Allocation of Overhead Costs | |||||||||||||||||
Overhead costs associated with office facilities, IT and certain depreciation related to non cloud-based infrastructure hardware equipment are allocated to cost of revenues and operating expenses based on headcount. Facility costs associated with our data centers as well as depreciation related to our cloud-based infrastructure hardware equipment is classified as cost of subscription revenues. | |||||||||||||||||
Revenue Recognition | |||||||||||||||||
We derive our revenues from two sources: (i) subscriptions and (ii) professional services and other. Subscription revenues are primarily comprised of subscription fees that give customers access to the ordered subscription service, related support and updates to the subscribed service during the subscription term. | |||||||||||||||||
Our contracts typically do not give the customer the right to take possession of the software supporting the services. Professional services and other revenues consist of fees associated with the implementation and configuration of our services. Professional services and other revenues also include customer training and attendance and sponsorship fees for Knowledge, our annual user conference. | |||||||||||||||||
We commence revenue recognition when all of the following conditions are met: | |||||||||||||||||
•There is persuasive evidence of an arrangement; | |||||||||||||||||
•The service has been provided to the customer; | |||||||||||||||||
•The collection of related fees is reasonably assured; and | |||||||||||||||||
•The amount of fees to be paid by the customer is fixed or determinable. | |||||||||||||||||
We recognize subscription revenues ratably over the contract term beginning on the commencement date of each contract, the date we make our services available to our customers. Once our services are available to customers, we record amounts due in accounts receivable and in deferred revenue. | |||||||||||||||||
We recognize professional services revenues as the services are delivered using a proportional performance model. Such services are delivered over a short period of time. In instances where final acceptance of the services are required before revenues are recognized, we defer professional services revenues and the associated costs until all acceptance criteria have been met. | |||||||||||||||||
We have multiple element arrangements comprised of subscription fees and professional services. In October 2009, the Financial Accounting Standards Board, or FASB, ratified authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables effective for fiscal periods beginning on or after June 15, 2010. Upon adoption of this authoritative accounting guidance, we began to account for subscription and professional services revenues as separate units of accounting. To qualify as a separate unit of accounting, the delivered item must have value to the customer on a standalone basis. We have concluded that our subscription service has standalone value as it is routinely sold separately by us. In addition, the applications offered through this subscription service are fully functional without any additional development, modification or customization. We provide customers access to our subscription service at the beginning of the contract term. In determining whether professional services have standalone value, we considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the subscription service start date and the contractual dependence of the subscription service on the customer’s satisfaction with the professional services work. Our professional services, including implementation and configuration services, are not so unique and complex that other vendors cannot provide them. In some instances, customers independently contract with third-party vendors to do the implementation and we regularly outsource implementation services to contracted third-party vendors. As a result, we concluded professional services, including implementation and configuration services, have standalone value. | |||||||||||||||||
We determine the selling price of each deliverable in the arrangement using the selling price hierarchy. Under the selling price hierarchy, the selling price for each deliverable is determined using vendor-specific objective evidence, or VSOE, of selling price or third-party evidence, or TPE, of selling price if VSOE does not exist. If neither VSOE nor TPE of selling price exists for a deliverable, the selling price is determined using the best estimate of selling price, or BESP. The selling price for each unit of accounting is based on the BESP since VSOE and TPE are not available for our subscription service or professional services and other. The BESP for each deliverable is determined primarily by considering the historical selling price of these deliverables in similar transactions as well as other factors, including, but not limited to, market competition, review of stand-alone sales and current pricing practices. In determining the appropriate pricing structure, we consider the extent of competitive pricing of similar products and marketing analysis. The total arrangement fee for these multiple element arrangements is then allocated to the separate units of accounting based on the relative selling price. The BESP for our subscription service is based upon the historical selling price of these deliverables. | |||||||||||||||||
In limited circumstances, we grant certain customers the right to deploy our subscription service on the customers’ own servers without significant penalty. These arrangements are subject to software revenue recognition guidance since the customer deploys our software. We have analyzed all of the elements in these particular multiple element arrangements and determined that we do not have sufficient VSOE of fair value to allocate revenue to our subscription service and professional services. Consequently, we defer all revenue and related costs under the arrangement until the last element in the transaction has been delivered or started to be delivered. Once the subscription service and the professional services have commenced, we recognize the entire fee and related costs from the arrangement ratably over the remaining period of the arrangement. | |||||||||||||||||
Deferred revenue consists primarily of payments received in advance of revenue recognition for our subscriptions and professional services and other revenues and is recognized as the revenue recognition criteria are met. | |||||||||||||||||
Deferred Commissions | |||||||||||||||||
Deferred commissions are the incremental selling costs that are directly associated with our customer contracts and consist of sales commissions paid to our direct sales force and referral fees paid to independent third-parties. The majority of commissions and referral fees are deferred and amortized on a straight-line basis over the terms of the related customer contracts. We include amortization of deferred commissions in sales and marketing expense in the consolidated statements of comprehensive loss. | |||||||||||||||||
Fair Value Measurements | |||||||||||||||||
We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized in the financial statements on a non-recurring basis or disclosed at fair value in the financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We use a fair value hierarchy that is based on three levels of inputs, of which the first two are considered observable and the last unobservable. The three levels of the fair value hierarchy are as follows: | |||||||||||||||||
Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; | |||||||||||||||||
Level 2—Inputs other than Level 1 that are directly or indirectly observable, such as quoted prices for identical or similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities, such as interest rates, yield curves and foreign currency spot rates; and | |||||||||||||||||
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. | |||||||||||||||||
Cash and Cash Equivalents | |||||||||||||||||
Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. Cash and cash equivalents are stated at cost, which approximates fair value. | |||||||||||||||||
Investments | |||||||||||||||||
Investments consist of commercial paper, corporate notes and bonds, certificates of deposit and U.S. government agency securities. We classify investments as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive loss, a component of stockholders’ equity. We evaluate our investments to assess whether those with unrealized loss positions are other than temporarily impaired. We consider impairments to be other than temporary if they are related to deterioration in credit risk or if it is likely we will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in interest and other income (expense), net in the consolidated statements of comprehensive loss. | |||||||||||||||||
Accounts Receivable | |||||||||||||||||
We record trade accounts receivable at the net invoice value and such receivables are non-interest bearing. We consider receivables past due based on the contractual payment terms. We review our exposure to accounts receivable and reserve for specific amounts if collectibility is no longer reasonably assured. | |||||||||||||||||
Property and Equipment | |||||||||||||||||
Property and equipment, net, are stated at cost, subject to review of impairment, and depreciated using the straight-line method over the estimated useful lives of the assets as follows: | |||||||||||||||||
Computer equipment and software | 3—5 years | ||||||||||||||||
Furniture and fixtures | 3—5 years | ||||||||||||||||
Leasehold improvements | shorter of the lease term or estimated useful life | ||||||||||||||||
When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in operating expenses. Repairs and maintenance expenses are charged to our statements of comprehensive loss as incurred. | |||||||||||||||||
Capitalized Software Costs | |||||||||||||||||
Costs incurred to develop our internal administration, finance and accounting systems are capitalized during the application development stage and amortized over the software’s estimated useful life of three to five years. | |||||||||||||||||
Leases | |||||||||||||||||
Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations or periods during the lease term where rent is not required, we recognize rent expense based on allocating the total rent payable on a straight-line basis over the term of the lease excluding lease extension periods. The difference between rent payments and straight-line rent expense is recorded as deferred rent in the consolidated balance sheets. Deferred rent that will be recognized during the ensuing 12-month period is recorded as the current portion of deferred rent and the remainder is recorded as long-term deferred rent. | |||||||||||||||||
Goodwill, Intangible Assets and Other Long Lived Assets | |||||||||||||||||
Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. We evaluate and test the recoverability of goodwill for impairment at least annually, during the fourth quarter, or more frequently if circumstances indicate that goodwill may not be recoverable. | |||||||||||||||||
Intangible assets are amortized over their useful lives ranging from 18 months to seven years. Each period we evaluate the estimated remaining useful life of purchased intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining period of amortization. | |||||||||||||||||
We periodically review the carrying amounts of these assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. We measure the recoverability of these assets by comparing the carrying amount of each asset to the future undiscounted cash flows we expect the asset to generate. If we consider any of these assets to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. | |||||||||||||||||
Convertible Preferred Stock | |||||||||||||||||
Prior to the closing of the initial public offering, or IPO, we had four series of convertible preferred stock outstanding. We recorded the convertible preferred stock at fair value on the dates of issuance, net of issuance costs. We classified the convertible preferred stock outside of stockholders’ equity because the shares contained liquidation features that were not solely within our control. | |||||||||||||||||
Upon the closing of our IPO on July 5, 2012, all of the outstanding 10,462,877 shares of convertible preferred stock automatically converted into an aggregate of 83,703,016 shares of common stock. As of December 31, 2014 and 2013, we had no shares of preferred stock outstanding. | |||||||||||||||||
Stock-based Compensation | |||||||||||||||||
We recognize compensation expense related to stock options and restricted stock units, or RSUs, on a straight-line basis over the requisite service period, which is generally the vesting term of four years. For RSUs granted with a performance condition, the expenses are recognized on a graded vesting basis over the vesting period, after assessing the probability of achieving requisite performance criteria. This has the impact of greater stock-based compensation expense during the initial years of the vesting period as stock-based compensation cost is recognized over the requisite service period for each separately vesting tranche of the award as though the award were, in substance, multiple awards. We recognize compensation expense related to shares issued pursuant to the employee stock purchase plan, or ESPP, on a straight-line basis over the offering period. We estimate the fair value of options using the Black-Scholes options pricing model and fair value of RSUs using the fair value of our common stock on the date of grant. We recognize compensation expense net of estimated forfeiture activity, which is based on historical forfeiture rates. | |||||||||||||||||
Net Loss Per Share Attributable to Common Stockholders | |||||||||||||||||
We compute net income (loss) attributable to common stockholders using the two-class method required for participating securities. We consider our convertible preferred stock that was outstanding prior to the close of our IPO and shares of common stock subject to repurchase resulting from the early exercise of stock options to be participating securities since they contain non-forfeitable rights to dividends or dividend equivalents in the event we declare a dividend for common stock. In accordance with the two-class method, earnings allocated to these participating securities, are subtracted from net income after deducting preferred stock dividends and accretion to the redemption value of the Series A, Series B and Series C to determine total undistributed earnings to be allocated to common stockholders. The holders of our convertible preferred stock did not have a contractual obligation to share in our net losses and such shares were excluded from the computation of basic earnings per share in periods of net loss. | |||||||||||||||||
Basic net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. All participating securities are excluded from basic weighted-average common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, adjusted for the effects of dilutive common shares, which are comprised of outstanding common stock options, convertible preferred stock, RSUs, common stock subject to repurchase, ESPP obligations, convertible senior notes and warrants. The dilutive potential common shares are computed using the treasury stock method or the as-if converted method, as applicable. In periods where the effect of the conversion of preferred stock is dilutive, net income (loss) attributable to common stockholders is adjusted by the associated preferred dividends and accretions. The effects of outstanding common stock options, convertible preferred stock, RSUs, common stock subject to repurchase, ESPP obligations, convertible senior notes and warrants are excluded from the computation of diluted net income (loss) per common share in periods in which the effect would be antidilutive. | |||||||||||||||||
Concentration of Credit Risk and Significant Customers | |||||||||||||||||
Financial instruments potentially exposing us to credit risk consist primarily of cash, cash equivalents, investments, accounts receivable. We maintain cash, cash equivalents and investments at financial institutions that management believes are high credit, quality financial institutions. We invest in securities with a minimum rating of A by Standard & Poor's and A-2 by Moody's. We are also exposed to credit risk under the convertible note hedge (the "Note Hedge") transactions that may result from counterparties' non-performance. | |||||||||||||||||
Credit risk arising from accounts receivable is mitigated due to our large number of customers and their dispersion across various industries and geographies. As of December 31, 2014 and 2013, there were no customers that represented more than 10% of our accounts receivable balance. There were no customers that individually exceeded 10% of our revenues in any of the periods presented. | |||||||||||||||||
We review the composition of the accounts receivable balance, historical write-off experience and the potential risk of loss associated with delinquent accounts to determine if an allowance for doubtful accounts is necessary. Individual accounts receivable are written off when we become aware of a specific customer’s inability to meet its financial obligation, and all collection efforts are exhausted. The following table presents the changes in the allowance for doubtful accounts (in thousands): | |||||||||||||||||

Warranties and Indemnification | |||||||||||||||||
Our cloud-based service to automate enterprise service operations is typically warranted to perform in material conformance with specifications. | |||||||||||||||||
We include service level commitments to our customers that permit those customers to receive credits in the event we fail to meet those levels. We establish an accrual based on historical credits paid and an evaluation of the performance of our services including an assessment of the impact, if any, of any known service disruptions. Service level credit accrual charges are recorded against revenue. The following table presents the changes in the service level credit accrual (in thousands): | |||||||||||||||||

We have also agreed to indemnify our directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by us, arising out of that person’s services as a director or officer of our company or that person’s services provided to any other company or enterprise at our request. We maintain director and officer insurance coverage that may enable us to recover a portion of any future amounts paid. The fair values of these obligations are not material as of each balance sheet date. | |||||||||||||||||
Our arrangements include provisions indemnifying customers against intellectual property and other third-party claims. We have not incurred any costs as a result of such indemnifications and have not recorded any liabilities related to such obligations in the consolidated financial statements. | |||||||||||||||||
Income Taxes | |||||||||||||||||
We use the asset and liability method of accounting for income taxes, in which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed. We recognize the effect on deferred tax assets and liabilities of a change in tax rates as income and expense in the period that includes the enactment date. A valuation allowance is established if it is more likely than not that all or a portion of the deferred tax asset will not be realized. In determining the need for a valuation allowance, we consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, carry-forward periods, and prudent and feasible tax planning strategies. | |||||||||||||||||
Our tax positions are subject to income tax audits by multiple tax jurisdictions throughout the world. We recognize the tax benefit of an uncertain tax position only if it is more likely than not the position is sustainable upon examination by the taxing authority, based on the technical merits. We measure the tax benefit recognized as the largest amount of benefit which is more likely than not to be realized upon settlement with the taxing authority. We recognize interest accrued and penalties related to unrecognized tax benefits in our tax provision. | |||||||||||||||||
We calculate the current and deferred income tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed in subsequent years and record adjustments based on filed income tax returns when identified. The amount of income taxes paid is subject to examination by U.S. federal, state and foreign tax authorities. The estimate of the potential outcome of any uncertain tax issue is subject to management’s assessment of relevant risks, facts and circumstances existing at that time. To the extent the assessment of such tax position changes, we record the change in estimate in the period in which we make the determination. | |||||||||||||||||
Recent Accounting Pronouncements | |||||||||||||||||
In May 2014, the Financial Accounting Standards Board, or FASB, issued an update to ASC 606 Revenue from Contracts with Customers, or ASC 606, that will supersede virtually all existing revenue guidance. Under this update, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This update should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. This guidance will become effective for us for our interim and annual reporting periods beginning January 1, 2017. We are currently evaluating the impact of this update on our consolidated financial statements. |

Acquisition [Abstract] | ||||||||
Acquisition | Acquisitions | |||||||
Neebula Systems Ltd. | ||||||||
On July 11, 2014, we completed the acquisition of a privately-held company, Neebula Systems Ltd., or Neebula, by acquiring all issued and outstanding common shares of Neebula for approximately $100 million in an all-cash transaction. Neebula’s flagship product, ServiceWatch, automates the discovery, mapping and monitoring of IT-enabled enterprise services. The acquisition will expand the overall capabilities of our IT operations management offerings. The following table summarizes the allocation of the purchase price to the fair value of the tangible and intangible assets acquired and liabilities assumed as of the acquisition date: | ||||||||
Purchase Price Allocation | Useful Life | |||||||
(in thousands) | (in years) | |||||||
Net tangible assets acquired | $ | 102 | ||||||
Intangible assets: | ||||||||

-1 | Deferred tax liabilities, net primarily relates to purchased identifiable intangible assets and is shown net of deferred tax assets. | |||||||
The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. We believe the goodwill represents the synergies expected from expanded market opportunities when integrating Neebula technologies with our offerings. The goodwill balance is not deductible for U.S. income tax purposes. Acquisition-related costs of $1.2 million are primarily included in general and administrative expenses on our consolidated statements of comprehensive loss. | ||||||||
The results of operations of Neebula have been included in our consolidated financial statements from the date of purchase. The following pro forma consolidated financial information combines the unaudited results of operations for us and Neebula for the year ended December 31, 2014 and 2013, as if the acquisition of Neebula had occurred on January 1, 2013 (in thousands, except share and per share data): | ||||||||

The pro forma results include adjustments primarily related to amortization of acquired intangible assets and acquisition-related costs. | ||||||||
Mirror42 Holding B.V. | ||||||||
On July 1, 2013, we acquired all the outstanding stock of Mirror42 Holding B.V., a cloud-based performance analytics company, for total cash consideration of $13.3 million. We believe this acquisition accelerates our ability to deliver on enterprise requirements for advanced business intelligence. | ||||||||
The following table summarizes the allocation of the purchase price to the fair value of the tangible and intangible assets acquired and liabilities assumed as of the acquisition date: | ||||||||
Purchase Price Allocation | Useful Life | |||||||

Goodwill | 8,218 | |||||||
Net deferred tax liabilities | (139 | ) | ||||||
Total purchase price | $ | 13,342 | ||||||
The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. Management believes that the goodwill represents the synergies expected from expanded market opportunities when integrating the Mirror42 Holding B.V.’s technologies with our offerings. $8.1 million of the goodwill balance is deductible for income tax purposes. | ||||||||
The results of operations of Mirror42 Holding B.V. described above have been included in our consolidated financial statements from the date of purchase. Our business combination did not have a material impact on our consolidated financial statements, and therefore pro forma disclosures have not been presented. |

Convertible Notes Payable [Abstract] | ||||||||
Notes Payable | Convertible Senior Notes | |||||||
In November 2013, we issued 0% convertible senior notes due November 1, 2018 with aggregate principal amount of $575 million (the "Notes"). The Notes will not bear interest. The Notes mature on November 1, 2018 unless converted or repurchased in accordance with their terms prior to such date. We cannot redeem the Notes prior to maturity. | ||||||||
The Notes are unsecured obligations and do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries. | ||||||||
Upon conversion, we may choose to pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock. We intend to settle the principal amount of the Notes with cash. | ||||||||
The Notes are convertible up to 7.8 million shares of our common stock at an initial conversion rate of approximately 13.54 shares of common stock per $1,000 principal amount, which is equal to an initial conversion price of approximately $73.88 per share of common stock, subject to adjustment. Holders of the Notes may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding July 1, 2018, only under the following circumstances: | ||||||||
• | during any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (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 the 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 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 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 on each such trading day; or | |||||||
• | upon the occurrence of specified corporate events. | |||||||
On or after July 1, 2018, a holder may convert all or any portion of its notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election | ||||||||
The conversion price will be subject to adjustment in some events. Holders of the Notes who convert their notes in connection with certain corporate events that constitute a “make-whole fundamental change” are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a corporate event that constitutes a “fundamental change,” holders of the Notes may require us to purchase with cash all or a portion of the Notes upon the occurrence of a fundamental change, at a purchase price equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest. | ||||||||
In accounting for the issuance of the notes, we separated the Notes into liability and equity components. The carrying cost of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the proceeds allocated to the liability component (“debt discount”) is amortized to interest expense using the effective interest method over the term of the Note. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. | ||||||||
In accounting for the transaction costs related to the issuance of the Notes, we allocated the total amount incurred to the liability and equity components based on their relative values. Transaction costs attributable to the liability component are being amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component were netted with the equity component of the Notes in stockholders’ equity. Additionally, we recorded a net deferred tax liability of $6.6 million in connection with the Notes and convertible notes hedge transactions described below. The Notes consisted of the following (in thousands): | ||||||||

Equity(1): | $ | 152,061 | $ | 152,061 | ||||
-1 | Included in the consolidated balance sheets within additional paid-in capital. | |||||||
We consider the fair value of the Notes at December 31, 2014 and 2013 to be a Level 2 measurement. The estimated fair values of the Notes at December 31, 2014 was $653.3 million. The fair value was determined based on the closing trading price per $100 of the Notes on December 31, 2014. Based on the closing price of our common stock of $67.85 and $56.01 on December 31, 2014 and 2013, the if-converted value of the Notes was less than its principal amount. | ||||||||
As of December 31, 2014, the remaining life of the Notes is 46 months. The following table sets forth total interest expense recognized related to the Notes (in thousands): | ||||||||

Effective interest rate of the liability component | 6.50% | |||||||
There was no interest expense recognized in the year ended December 31, 2012 related to the Notes. | ||||||||
Note Hedge | ||||||||
To minimize the impact of potential economic dilution upon conversion of the Notes, we entered into convertible note hedge transactions with respect to our common stock concurrent with the issuance of the Notes. The Note Hedge covers approximately 7.8 million shares of our common stock at a strike price per share that corresponds to the initial conversion price of the Notes, are also subject to adjustment, and are exercisable upon conversion of the Notes. We paid an aggregate amount of $135.8 million for the Note Hedge. The Note Hedge will expire upon maturity of the Notes. The Note Hedge is intended to reduce the potential economic dilution upon conversion of the Notes in the event that the fair value per share of our common stock at the time of exercise is greater than the conversion price of the Notes. The Note Hedge is a separate transaction and is not part of the terms of the Notes. The Note Hedge does not impact earnings per share, as it was entered into to offset any dilution from the Notes. | ||||||||
Warrants | ||||||||
Separately, we entered into warrant transactions (the “Warrants”) whereby we sold warrants to acquire up to 7.8 million shares of our common stock, at a strike price of $107.46 per share, subject to adjustments. We received aggregate proceeds of $84.5 million from the sale of the Warrants. If the average market value per share of our common stock for the reporting period, as measured under the Warrants, exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on our earnings per share. The Warrants are separate transactions and are not remeasured through earnings each reporting period. The Warrants are not part of the Notes or the Note Hedge, and have been accounted for as part of additional paid-in capital. |

Stock-Based Compensation | Stock Awards | ||||||||||||
We have a 2005 Stock Option Plan, or 2005 Plan, which provides for grants of stock awards, including options to purchase shares of common stock, stock purchase rights and RSUs to certain employees, officers, directors and consultants. As of December 31, 2014, there were 53,355,641 total shares of common stock authorized for issuance under the 2005 Plan, which includes shares already issued under such plan and shares reserved for issuance pursuant to outstanding options and RSUs. | |||||||||||||
On April 27, 2012, the board of directors approved the 2012 Equity Incentive Plan, or 2012 Plan and the 2012 Employee Stock Purchase Plan, or the 2012 ESPP, which became effective on June 27, 2012 and June 28, 2012, respectively. | |||||||||||||
Our 2012 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, RSUs, performance-based stock awards and other forms of equity compensation, or collectively, stock awards. In addition, the 2012 Plan provides for the grant of performance cash awards. Incentive stock options may be granted only to employees. All other awards may be granted to employees, including officers, as well as directors and consultants. The share reserve may increase to the extent that outstanding stock options under the 2005 Plan expire or terminate unexercised. The share reserve also automatically increases on January 1 of each year until January 1, 2022, by up to 5% of the total number of shares of the common stock outstanding on December 31 of the preceding year as determined by the board of directors. As of December 31, 2014, there were 29,160,914 total shares of common stock authorized for issuance under the 2012 Plan, excluding 7,475,454 shares of common stock automatically added to the 2012 Plan on January 1, 2015 pursuant to the provision described in the preceding sentence. | |||||||||||||
Our 2012 ESPP authorizes the issuance of shares of common stock pursuant to purchase rights granted to our employees. The number of shares of common stock reserved for issuance automatically increases on January 1 of each year, from January 1, 2013 through January 1, 2022, by up to 1% of the total number of shares of the common stock outstanding on December 31 of the preceding year. The price at which common stock is purchased under the 2012 ESPP is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. Offering periods are six months long and begin on February 1 and August 1 of each year. As of December 31, 2014, we had 6,529,516 total shares of common stock reserved for issuance under the 2012 ESPP, excluding 1,495,090 shares of common stock automatically added to the 2012 Plan on January 1, 2015. | |||||||||||||
Stock Options | |||||||||||||
The stock options are exercisable at a price equal to the market value of the underlying shares of common stock on the date of the grant as determined by our board of directors or, for those stock options issued subsequent to our IPO, the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. Stock options granted under our 2005 Plan and the 2012 Plan to new employees generally vest 25% one year from the date the requisite service period begins and continue to vest monthly for each month of continued employment over the remaining three years. Options granted generally are exercisable for a period of up to 10 years. Option holders under the 2005 Plan can exercise unvested options to acquire restricted stock. Upon termination of service, we have the right to repurchase at the original purchase price any unvested (but issued) shares of common stock. | |||||||||||||

These performance RSUs were considered as eligible to vest when approved by the Compensation Committee in January 2015. Shares earned will vest in four quarterly increments starting from February 2016, contingent on the continuous employment of each executive. We recognized $19.2 million of stock-based compensation expense associated with these performance RSUs during the year ended December 31, 2014. | |||||||||||||

We use the Black-Scholes options pricing model to estimate the fair value of our stock option grants.

The following assumptions were used for each respective period to calculate our stock-based compensation for each stock option grant on the date of the grant: | |||||||||||||

Expected volatility. We use the historic volatility of publicly traded peer companies as an estimate for expected volatility. In considering peer companies, characteristics such as industry, stage of development, size and financial leverage are considered. We intend to continue to consistently apply this process using the same or similar public companies until a sufficient amount of historical information regarding the volatility of our own common stock share price becomes available. | |||||||||||||
Expected term. We estimate the expected term for stock options using the simplified method due to the lack of historical exercise activity for our company. The simplified method calculates the expected term as the mid-point between the vesting date and the contractual expiration date of the award. We estimate the expected term for ESPP using the purchase period. | |||||||||||||
Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock-based award. | |||||||||||||
Expected dividend yield. Our expected dividend yield is zero, as we have not and do not currently intend to declare dividends in the foreseeable future. | |||||||||||||
Fair value of common stock. Prior to our IPO in June 2012, the fair value of our common stock was determined by our board of directors, which intended all options granted to be exercisable at a price per share not less than the per share fair value of the common stock underlying those options on the date of grant. The valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions used in the valuation model are based on future expectations combined with management judgment. | |||||||||||||
From March 2010 until our IPO in June 2012, we utilized the probability weighted expected return method, or PWERM, approach to allocate value to our common shares. The PWERM approach employs various market approach and income approach calculations depending upon the likelihood of various liquidation scenarios. For each of the various scenarios, an equity value is estimated and the rights and preferences for each stockholder class are considered to allocate the equity value to common shares. The common share value is then multiplied by a discount factor reflecting the calculated discount rate and the timing of the event. Lastly, the common share value is multiplied by an estimated probability for each scenario. The probability and timing of each scenario was based upon discussions between our board of directors and our management team. Under the PWERM, the value of our common stock was based upon four possible future events for our company: an IPO; a strategic merger or sale; remaining a private company; and dissolution. | |||||||||||||
For stock options granted subsequent to our IPO, the fair value is based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. |

As of December 31, 2014, there were 53,355,641 total shares of common stock authorized for issuance under the 2005 Plan, which includes shares already issued under such plan and shares reserved for issuance pursuant to outstanding options and RSUs. | |||||||||||||
On April 27, 2012, the board of directors approved the 2012 Equity Incentive Plan, or 2012 Plan and the 2012 Employee Stock Purchase Plan, or the 2012 ESPP, which became effective on June 27, 2012 and June 28, 2012, respectively. | |||||||||||||
Our 2012 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, RSUs, performance-based stock awards and other forms of equity compensation, or collectively, stock awards. In addition, the 2012 Plan provides for the grant of performance cash awards. Incentive stock options may be granted only to employees. All other awards may be granted to employees, including officers, as well as directors and consultants. The share reserve may increase to the extent that outstanding stock options under the 2005 Plan expire or terminate unexercised. The share reserve also automatically increases on January 1 of each year until January 1, 2022, by up to 5% of the total number of shares of the common stock outstanding on December 31 of the preceding year as determined by the board of directors. As of December 31, 2014, there were 29,160,914 total shares of common stock authorized for issuance under the 2012 Plan, excluding 7,475,454 shares of common stock automatically added to the 2012 Plan on January 1, 2015 pursuant to the provision described in the preceding sentence. | |||||||||||||
Our 2012 ESPP authorizes the issuance of shares of common stock pursuant to purchase rights granted to our employees. The number of shares of common stock reserved for issuance automatically increases on January 1 of each year, from January 1, 2013 through January 1, 2022, by up to 1% of the total number of shares of the common stock outstanding on December 31 of the preceding year. The price at which common stock is purchased under the 2012 ESPP is equal to 85% of the fair market value of the common stock on the first or last day of the offering period, whichever is lower. Offering periods are six months long and begin on February 1 and August 1 of each year. As of December 31, 2014, we had 6,529,516 total shares of common stock reserved for issuance under the 2012 ESPP, excluding 1,495,090 shares of common stock automatically added to the 2012 Plan on January 1, 2015. | |||||||||||||
Stock Options | |||||||||||||
The stock options are exercisable at a price equal to the market value of the underlying shares of common stock on the date of the grant as determined by our board of directors or, for those stock options issued subsequent to our IPO, the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. Stock options granted under our 2005 Plan and the 2012 Plan to new employees generally vest 25% one year from the date the requisite service period begins and continue to vest monthly for each month of continued employment over the remaining three years. Options granted generally are exercisable for a period of up to 10 years. Option holders under the 2005 Plan can exercise unvested options to acquire restricted stock. Upon termination of service, we have the right to repurchase at the original purchase price any unvested (but issued) shares of common stock. | |||||||||||||

Aggregate intrinsic value represents the difference between the estimated fair value of our common stock and the exercise price of outstanding, in-the-money options. The total intrinsic value of the options exercised was $84.2 million the year ended December 31, 2012.

RSUs granted under the 2005 Plan and the 2012 Plan to employees generally vest over a four-year period. Included in the number of shares granted during the year ended December 31, 2014 were 585,000 RSU with both service and performance-based vesting criteria that were granted to certain executives. These performance RSUs were considered as eligible to vest when approved by the Compensation Committee in January 2015. Shares earned will vest in four quarterly increments starting from February 2016, contingent on the continuous employment of each executive. We recognized $19.2 million of stock-based compensation expense associated with these performance RSUs during the year ended December 31, 2014. | |||||||||||||
As of December 31, 2014, total unrecognized compensation cost, adjusted for estimated forfeitures, related to unvested RSUs was approximately $383.4 million and the weighted-average remaining vesting period was 3.15 years. | |||||||||||||
Stock-Based Compensation | |||||||||||||
We use the Black-Scholes options pricing model to estimate the fair value of our stock option grants. This model incorporates various assumptions including expected volatility, expected term, risk-free interest rates and expected dividend yields. The following assumptions were used for each respective period to calculate our stock-based compensation for each stock option grant on the date of the grant: | |||||||||||||

Expected volatility. We use the historic volatility of publicly traded peer companies as an estimate for expected volatility. In considering peer companies, characteristics such as industry, stage of development, size and financial leverage are considered. We intend to continue to consistently apply this process using the same or similar public companies until a sufficient amount of historical information regarding the volatility of our own common stock share price becomes available. | |||||||||||||
Expected term. We estimate the expected term for stock options using the simplified method due to the lack of historical exercise activity for our company. The simplified method calculates the expected term as the mid-point between the vesting date and the contractual expiration date of the award. We estimate the expected term for ESPP using the purchase period. | |||||||||||||
Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock-based award. | |||||||||||||
Expected dividend yield. Our expected dividend yield is zero, as we have not and do not currently intend to declare dividends in the foreseeable future. | |||||||||||||
Fair value of common stock. Prior to our IPO in June 2012, the fair value of our common stock was determined by our board of directors, which intended all options granted to be exercisable at a price per share not less than the per share fair value of the common stock underlying those options on the date of grant. The valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions used in the valuation model are based on future expectations combined with management judgment. | |||||||||||||
From March 2010 until our IPO in June 2012, we utilized the probability weighted expected return method, or PWERM, approach to allocate value to our common shares. The PWERM approach employs various market approach and income approach calculations depending upon the likelihood of various liquidation scenarios. For each of the various scenarios, an equity value is estimated and the rights and preferences for each stockholder class are considered to allocate the equity value to common shares. The common share value is then multiplied by a discount factor reflecting the calculated discount rate and the timing of the event. Lastly, the common share value is multiplied by an estimated probability for each scenario. The probability and timing of each scenario was based upon discussions between our board of directors and our management team. Under the PWERM, the value of our common stock was based upon four possible future events for our company: an IPO; a strategic merger or sale; remaining a private company; and dissolution. | |||||||||||||
For stock options granted subsequent to our IPO, the fair value is based on the closing price of our common stock as reported on the New York Stock Exchange on the date of grant. |

As of December 31, 2014, we had U.S. federal net operating loss and federal tax credit carryforwards of approximately $704.5 million and $17.1 million, respectively. The federal net operating loss carryforwards and federal tax credits will begin to expire in 2024 if not utilized. In addition, we had state net operating loss and state tax credit carryforwards of approximately $244.7 million and $12.8 million, respectively. The state net operating loss and tax credit carryforwards will begin to expire in 2019 if not utilized. Utilization of our net operating loss and credit carryforwards may be subject to annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of the net operating loss and tax credit carry forwards before utilization. | ||||||||||||
Approximately $678.2 million of federal net operating losses and $215.9 million of state net operating losses relate to stock-based compensation deductions in excess of book expense, the tax effect of which would be to credit additional paid-in capital, if realized. | ||||||||||||
We maintain a full valuation allowance against our U.S. deferred tax assets as of December 31, 2014. We regularly assess the need for a valuation allowance against our deferred tax assets. In making that assessment, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets to determine, based on the weight of available evidence, whether it is more likely than not that some or all of the deferred tax assets will not be realized. Due to cumulative losses over recent years and based on all available evidence, we have determined that it is more likely than not that net deferred tax assets in the U.S. will not be realized. We have determined that $2.7 million related to deferred tax assets in certain foreign jurisdictions should be realized since certain foreign entities have cumulative income, and expected future income. The valuation allowance increased $36.6 million for the year ended December 31, 2014, increased $12.5 million for the year ended December 31, 2013 and decreased $0.6 million for the year ended December 31, 2012. The change in valuation allowance between the years ended December 31, 2014 and 2013 is primarily attributable to a decrease of deferred tax liabilities related to the Notes and an increase of deferred tax assets related to stock-based compensation, net operating losses, and the extension of the federal research and development tax credit for the year ended December 31, 2014. We will continue to assess the likelihood of realization of the deferred tax assets in each of the applicable jurisdictions in future periods and will adjust the valuation allowance accordingly. | ||||||||||||
We have not recorded a provision for deferred U.S. tax expense that could result from the remittance of foreign undistributed earnings since we intend to reinvest the earnings of these foreign subsidiaries indefinitely. | ||||||||||||
Our share of the undistributed earnings of foreign corporations not included in our consolidated federal income tax returns that could be subject to additional U.S. income tax if remitted was approximately two thousand dollars and $0.5 million as of December 31, 2014 and 2013, respectively. The determination of the amount of unrecognized U.S federal deferred income tax liability for undistributed earnings is not practicable. | ||||||||||||

As of December 31, 2014, we had gross unrecognized tax benefits of approximately $9.2 million, of which $2.9 million would impact the effective tax rate, if recognized. We recognize accrued interest and penalties related to unrecognized tax benefits as income tax expense. Accrued interest and penalties included in our liability related to unrecognized tax benefits were $0.4 million at December 31, 2014 and 2013. The amount of unrecognized tax benefits could be reduced upon expiration of the applicable statutes of limitations. The potential reduction in unrecognized tax benefits during the next 12 months is not expected to be material. Interest and penalties accrued on these uncertain tax positions will be released upon the expiration of the statutes of limitations and these amounts are also not material. | ||||||||||||
We are subject to taxation in the United States and foreign jurisdictions. As of December 31, 2014, our tax years of 2005 to 2014 remain subject to examination in most jurisdictions. We are currently protesting the results of the examination by the U.S. Internal Revenue Service for the June 30, 2011 and December 31, 2011 tax years. | ||||||||||||
There are differing interpretations of tax laws and regulations, and as a result, disputes may arise with tax authorities involving issues of the timing and amount of deductions and allocations of income among various tax jurisdictions. We periodically evaluate our exposures associated with our tax filing positions. We believe that adequate amounts have been reserved for any adjustments that may ultimately result from these examinations, and we do not anticipate a significant impact to our gross unrecognized tax benefits within the next twelve months related to these years. Although the timing of the resolution, settlement, and closure of any audit is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next twelve months. However, given the number of years that remain subject to examination, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. |

In February 2012, we signed a lease for our new San Diego office that was subsequently amended in December 2013. The lease is for approximately 155,443 square feet of office space with total minimum lease commitments of approximately $27.8 million. The lease commenced in August 2012 and will expire in September 2022. | ||||||||||||
During the year ended December 31, 2012, we relocated our San Diego office to another facility in San Diego. As part of this move, we incurred $2.5 million in lease abandonment costs, which primarily consists of a loss on disposal of assets recorded upon vacating our prior facility in August 2012. The lease on our prior San Diego facility does not expire until 2019 and we are currently subleasing the space. The cease-use loss was calculated as the present value of the remaining lease obligation offset by estimated sublease rental receipts during the remaining lease period, adjusted for deferred items and estimated lease incentives. As of December 31, 2014 and 2013, our facility exit obligation balance was $0.5 million and $1.4 million, respectively. The lease abandonment costs are included in general and administrative expense in our consolidated statements of comprehensive loss. | ||||||||||||
In September 2012, we signed a lease for a total of 43,590 square feet of office space located in Amsterdam. The square-footage for the first year is approximately 17,857 and increases incrementally over the term of the lease, with total minimum lease commitments of approximately $10.5 million. The lease commenced in October 2012 and has a term of 10.5 years. | ||||||||||||
In November, 2012, we entered into a lease agreement for 148,704 square feet of office space located in San Jose. The lease commenced in April 2013 and has a term of approximately 11 years. Rent is paid on a monthly basis and will increase incrementally over the term of the lease for total minimum lease payments of approximately $48.8 million. | ||||||||||||
In December 2014, we entered into a lease agreement for 328,867 square feet of space, located in Santa Clara. The initial term of the lease is expected to commence on August 15, 2015, although the commencement date may be extended in certain circumstances if specified improvements have not been completed by such date. The initial term shall be for 12 years following the commencement date, with two options to renew the lease for additional terms of five years each. Rent is paid on a monthly basis and will increase incrementally over the term of the lease for total minimum lease payments of approximately $151.1 million. | ||||||||||||
Legal Proceedings | ||||||||||||
From time to time, we are party to litigation and other legal proceedings in the ordinary course of business. While the results of any litigation or other legal proceedings are uncertain, management does not believe the ultimate resolution of any pending legal matters is likely to have a material adverse effect on our financial position, results of operations or cash flows, except as discussed below and for those matters for which we have recorded a loss contingency. We accrue for loss contingencies when it is both probable that we will incur the loss and when we can reasonably estimate the amount of the loss or range of loss. | ||||||||||||
Generally, our subscription agreements require us to defend our customers for third-party intellectual property infringement and other claims. Any adverse determination related to intellectual property claims or other litigation could prevent us from offering our services and adversely affect our financial condition and results of operations. | ||||||||||||
On February 6, 2014, Hewlett-Packard Company filed a lawsuit against us in the U.S. District Court for the Northern District of California that alleges that some of our services infringe the claims of eight of Hewlett-Packard's patents. Hewlett-Packard is seeking unspecified damages and an injunction. The court held case management conferences on June 26, 2014, September 4, 2014 and February 5, 2015. The parties are currently conducting discovery. Hewlett-Packard served infringement contentions on July 3, 2014 and November 18, 2014. We served invalidity contentions on January 9, 2015. A claim construction hearing is scheduled for June 12, 2015. Trial is currently scheduled to begin on May 16, 2016. We have filed petitions for inter partes review of all eight asserted patents with the United States Patent and Trademark Office. | ||||||||||||
On September 23, 2014, BMC Software, Inc. filed a lawsuit against us in the U.S. District Court for the Eastern District of Texas that alleges that some of our services willfully infringe the claims of seven of BMC’s patents. BMC is seeking unspecified damages and an injunction. Motions to dismiss and transfer venue are currently pending. BMC served infringement contentions on January 6, 2015. Our invalidity contentions are due March 3, 2015. A claim construction hearing is scheduled for July 10, 2015. Trial is currently scheduled to begin on March 14, 2016. | ||||||||||||
We intend to vigorously defend these lawsuits. These litigation matters are still in their early stages and the final outcome, including our liability, if any, with respect to the claims in the lawsuits, is uncertain. If an unfavorable outcome were to occur in either litigation, the impact could be material to our business, financial condition, cash flow or results of operations, depending on the specific circumstances of the outcome. We cannot make a reasonable estimate of the potential loss or range of loss, if any, arising from these matters. |

Summary of Significant Accounting Policies (Policies) | 12 Months Ended | ||||||||||||||||
Dec. 31, 2014 | |||||||||||||||||
Accounting Policies [Abstract] | |||||||||||||||||
Principles of Consolidation | Principles of Consolidation | ||||||||||||||||
The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, and include our accounts and the accounts of our wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated upon consolidation. | |||||||||||||||||
Use of Estimates | Use of Estimates | ||||||||||||||||
The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. | |||||||||||||||||
Segments | Segments | ||||||||||||||||
We define the term “chief operating decision maker” to be our Chief Executive Officer. Our chief operating decision maker allocates resources and assesses financial performance based upon discrete financial information at the consolidated level. Accordingly, we have determined that we operate in a single reporting segment. | |||||||||||||||||
Foreign Currency Translation | Foreign Currency Translation | ||||||||||||||||
The functional currencies for our foreign subsidiaries are primarily their local currencies. Assets and liabilities of the wholly-owned foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at each period end. Amounts classified in stockholders’ equity are translated at historical exchange rates. Revenues and expenses are translated at the average exchange rates during the period. The resulting translation adjustments are recorded in accumulated other comprehensive loss as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in interest and other income (expense), net within the consolidated statements of comprehensive loss. | |||||||||||||||||
Allocation of Overhead Costs | Allocation of Overhead Costs | ||||||||||||||||
Overhead costs associated with office facilities, IT and certain depreciation related to non cloud-based infrastructure hardware equipment are allocated to cost of revenues and operating expenses based on headcount. Facility costs associated with our data centers as well as depreciation related to our cloud-based infrastructure hardware equipment is classified as cost of subscription revenues. | |||||||||||||||||
Deferred Revenue | Revenue Recognition | ||||||||||||||||
We derive our revenues from two sources: (i) subscriptions and (ii) professional services and other. Subscription revenues are primarily comprised of subscription fees that give customers access to the ordered subscription service, related support and updates to the subscribed service during the subscription term. | |||||||||||||||||
Our contracts typically do not give the customer the right to take possession of the software supporting the services. Professional services and other revenues consist of fees associated with the implementation and configuration of our services. Professional services and other revenues also include customer training and attendance and sponsorship fees for Knowledge, our annual user conference. | |||||||||||||||||
We commence revenue recognition when all of the following conditions are met: | |||||||||||||||||
•There is persuasive evidence of an arrangement; | |||||||||||||||||
•The service has been provided to the customer; | |||||||||||||||||
•The collection of related fees is reasonably assured; and | |||||||||||||||||
•The amount of fees to be paid by the customer is fixed or determinable. | |||||||||||||||||
We recognize subscription revenues ratably over the contract term beginning on the commencement date of each contract, the date we make our services available to our customers. Once our services are available to customers, we record amounts due in accounts receivable and in deferred revenue. | |||||||||||||||||
We recognize professional services revenues as the services are delivered using a proportional performance model. Such services are delivered over a short period of time. In instances where final acceptance of the services are required before revenues are recognized, we defer professional services revenues and the associated costs until all acceptance criteria have been met. | |||||||||||||||||
We have multiple element arrangements comprised of subscription fees and professional services. In October 2009, the Financial Accounting Standards Board, or FASB, ratified authoritative accounting guidance regarding revenue recognition for arrangements with multiple deliverables effective for fiscal periods beginning on or after June 15, 2010. Upon adoption of this authoritative accounting guidance, we began to account for subscription and professional services revenues as separate units of accounting. To qualify as a separate unit of accounting, the delivered item must have value to the customer on a standalone basis. We have concluded that our subscription service has standalone value as it is routinely sold separately by us. In addition, the applications offered through this subscription service are fully functional without any additional development, modification or customization. We provide customers access to our subscription service at the beginning of the contract term. In determining whether professional services have standalone value, we considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the subscription service start date and the contractual dependence of the subscription service on the customer’s satisfaction with the professional services work. Our professional services, including implementation and configuration services, are not so unique and complex that other vendors cannot provide them. In some instances, customers independently contract with third-party vendors to do the implementation and we regularly outsource implementation services to contracted third-party vendors. As a result, we concluded professional services, including implementation and configuration services, have standalone value. | |||||||||||||||||
We determine the selling price of each deliverable in the arrangement using the selling price hierarchy. Under the selling price hierarchy, the selling price for each deliverable is determined using vendor-specific objective evidence, or VSOE, of selling price or third-party evidence, or TPE, of selling price if VSOE does not exist. If neither VSOE nor TPE of selling price exists for a deliverable, the selling price is determined using the best estimate of selling price, or BESP. The selling price for each unit of accounting is based on the BESP since VSOE and TPE are not available for our subscription service or professional services and other. The BESP for each deliverable is determined primarily by considering the historical selling price of these deliverables in similar transactions as well as other factors, including, but not limited to, market competition, review of stand-alone sales and current pricing practices. In determining the appropriate pricing structure, we consider the extent of competitive pricing of similar products and marketing analysis. The total arrangement fee for these multiple element arrangements is then allocated to the separate units of accounting based on the relative selling price. The BESP for our subscription service is based upon the historical selling price of these deliverables. | |||||||||||||||||
In limited circumstances, we grant certain customers the right to deploy our subscription service on the customers’ own servers without significant penalty. These arrangements are subject to software revenue recognition guidance since the customer deploys our software. We have analyzed all of the elements in these particular multiple element arrangements and determined that we do not have sufficient VSOE of fair value to allocate revenue to our subscription service and professional services. Consequently, we defer all revenue and related costs under the arrangement until the last element in the transaction has been delivered or started to be delivered. Once the subscription service and the professional services have commenced, we recognize the entire fee and related costs from the arrangement ratably over the remaining period of the arrangement. | |||||||||||||||||
Deferred revenue consists primarily of payments received in advance of revenue recognition for our subscriptions and professional services and other revenues and is recognized as the revenue recognition criteria are met. | |||||||||||||||||
Deferred Commissions | Deferred Commissions | ||||||||||||||||
Deferred commissions are the incremental selling costs that are directly associated with our customer contracts and consist of sales commissions paid to our direct sales force and referral fees paid to independent third-parties. The majority of commissions and referral fees are deferred and amortized on a straight-line basis over the terms of the related customer contracts. We include amortization of deferred commissions in sales and marketing expense in the consolidated statements of comprehensive loss. | |||||||||||||||||
Fair Value Measurements | Fair Value Measurements | ||||||||||||||||
We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized in the financial statements on a non-recurring basis or disclosed at fair value in the financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We use a fair value hierarchy that is based on three levels of inputs, of which the first two are considered observable and the last unobservable. The three levels of the fair value hierarchy are as follows: | |||||||||||||||||
Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; | |||||||||||||||||
Level 2—Inputs other than Level 1 that are directly or indirectly observable, such as quoted prices for identical or similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities, such as interest rates, yield curves and foreign currency spot rates; and | |||||||||||||||||
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. | |||||||||||||||||
Cash and Cash Equivalents | Cash and Cash Equivalents | ||||||||||||||||
Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. Cash and cash equivalents are stated at cost, which approximates fair value. | |||||||||||||||||
Investments | Investments | ||||||||||||||||
Investments consist of commercial paper, corporate notes and bonds, certificates of deposit and U.S. government agency securities. We classify investments as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. All investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive loss, a component of stockholders’ equity. We evaluate our investments to assess whether those with unrealized loss positions are other than temporarily impaired. We consider impairments to be other than temporary if they are related to deterioration in credit risk or if it is likely we will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in interest and other income (expense), net in the consolidated statements of comprehensive loss. | |||||||||||||||||
Accounts Receivable | Accounts Receivable | ||||||||||||||||
We record trade accounts receivable at the net invoice value and such receivables are non-interest bearing. We consider receivables past due based on the contractual payment terms. We review our exposure to accounts receivable and reserve for specific amounts if collectibility is no longer reasonably assured. | |||||||||||||||||
Property and Equipment | Property and Equipment | ||||||||||||||||
Property and equipment, net, are stated at cost, subject to review of impairment, and depreciated using the straight-line method over the estimated useful lives of the assets as follows: | |||||||||||||||||
Computer equipment and software | 3—5 years | ||||||||||||||||
Furniture and fixtures | 3—5 years | ||||||||||||||||
Leasehold improvements | shorter of the lease term or estimated useful life | ||||||||||||||||
When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in operating expenses. Repairs and maintenance expenses are charged to our statements of comprehensive loss as incurred. | |||||||||||||||||
Capitalized Software Costs | Capitalized Software Costs | ||||||||||||||||
Costs incurred to develop our internal administration, finance and accounting systems are capitalized during the application development stage and amortized over the software’s estimated useful life of three to five years. | |||||||||||||||||
Leases | Leases | ||||||||||||||||
Leases are reviewed and classified as capital or operating at their inception. For leases that contain rent escalations or periods during the lease term where rent is not required, we recognize rent expense based on allocating the total rent payable on a straight-line basis over the term of the lease excluding lease extension periods. The difference between rent payments and straight-line rent expense is recorded as deferred rent in the consolidated balance sheets. Deferred rent that will be recognized during the ensuing 12-month period is recorded as the current portion of deferred rent and the remainder is recorded as long-term deferred rent. | |||||||||||||||||
Goodwill, Intangible Assets and Other Long Lived Assets | Goodwill, Intangible Assets and Other Long Lived Assets | ||||||||||||||||
Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. We evaluate and test the recoverability of goodwill for impairment at least annually, during the fourth quarter, or more frequently if circumstances indicate that goodwill may not be recoverable. | |||||||||||||||||
Intangible assets are amortized over their useful lives ranging from 18 months to seven years. Each period we evaluate the estimated remaining useful life of purchased intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining period of amortization. | |||||||||||||||||
We periodically review the carrying amounts of these assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. We measure the recoverability of these assets by comparing the carrying amount of each asset to the future undiscounted cash flows we expect the asset to generate. If we consider any of these assets to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. | |||||||||||||||||
Convertible Preferred Stock | Convertible Preferred Stock | ||||||||||||||||
Prior to the closing of the initial public offering, or IPO, we had four series of convertible preferred stock outstanding. We recorded the convertible preferred stock at fair value on the dates of issuance, net of issuance costs. We classified the convertible preferred stock outside of stockholders’ equity because the shares contained liquidation features that were not solely within our control. | |||||||||||||||||
Upon the closing of our IPO on July 5, 2012, all of the outstanding 10,462,877 shares of convertible preferred stock automatically converted into an aggregate of 83,703,016 shares of common stock. As of December 31, 2014 and 2013, we had no shares of preferred stock outstanding. | |||||||||||||||||
Stock-based Compensation | Stock-based Compensation | ||||||||||||||||
We recognize compensation expense related to stock options and restricted stock units, or RSUs, on a straight-line basis over the requisite service period, which is generally the vesting term of four years. For RSUs granted with a performance condition, the expenses are recognized on a graded vesting basis over the vesting period, after assessing the probability of achieving requisite performance criteria. This has the impact of greater stock-based compensation expense during the initial years of the vesting period as stock-based compensation cost is recognized over the requisite service period for each separately vesting tranche of the award as though the award were, in substance, multiple awards. We recognize compensation expense related to shares issued pursuant to the employee stock purchase plan, or ESPP, on a straight-line basis over the offering period. We estimate the fair value of options using the Black-Scholes options pricing model and fair value of RSUs using the fair value of our common stock on the date of grant. We recognize compensation expense net of estimated forfeiture activity, which is based on historical forfeiture rates. | |||||||||||||||||
Net Income (Loss) Per Share Attributable to Common Stockholders | Net Loss Per Share Attributable to Common Stockholders | ||||||||||||||||
We compute net income (loss) attributable to common stockholders using the two-class method required for participating securities. We consider our convertible preferred stock that was outstanding prior to the close of our IPO and shares of common stock subject to repurchase resulting from the early exercise of stock options to be participating securities since they contain non-forfeitable rights to dividends or dividend equivalents in the event we declare a dividend for common stock. In accordance with the two-class method, earnings allocated to these participating securities, are subtracted from net income after deducting preferred stock dividends and accretion to the redemption value of the Series A, Series B and Series C to determine total undistributed earnings to be allocated to common stockholders. The holders of our convertible preferred stock did not have a contractual obligation to share in our net losses and such shares were excluded from the computation of basic earnings per share in periods of net loss. | |||||||||||||||||
Basic net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. All participating securities are excluded from basic weighted-average common shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, adjusted for the effects of dilutive common shares, which are comprised of outstanding common stock options, convertible preferred stock, RSUs, common stock subject to repurchase, ESPP obligations, convertible senior notes and warrants. The dilutive potential common shares are computed using the treasury stock method or the as-if converted method, as applicable. In periods where the effect of the conversion of preferred stock is dilutive, net income (loss) attributable to common stockholders is adjusted by the associated preferred dividends and accretions. The effects of outstanding common stock options, convertible preferred stock, RSUs, common stock subject to repurchase, ESPP obligations, convertible senior notes and warrants are excluded from the computation of diluted net income (loss) per common share in periods in which the effect would be antidilutive. | |||||||||||||||||
Concentration of Credit Risk and Significant Customers | Concentration of Credit Risk and Significant Customers | ||||||||||||||||
Financial instruments potentially exposing us to credit risk consist primarily of cash, cash equivalents, investments, accounts receivable. We maintain cash, cash equivalents and investments at financial institutions that management believes are high credit, quality financial institutions. We invest in securities with a minimum rating of A by Standard & Poor's and A-2 by Moody's. We are also exposed to credit risk under the convertible note hedge (the "Note Hedge") transactions that may result from counterparties' non-performance. | |||||||||||||||||
Credit risk arising from accounts receivable is mitigated due to our large number of customers and their dispersion across various industries and geographies. As of December 31, 2014 and 2013, there were no customers that represented more than 10% of our accounts receivable balance. There were no customers that individually exceeded 10% of our revenues in any of the periods presented. | |||||||||||||||||
We review the composition of the accounts receivable balance, historical write-off experience and the potential risk of loss associated with delinquent accounts to determine if an allowance for doubtful accounts is necessary. Individual accounts receivable are written off when we become aware of a specific customer’s inability to meet its financial obligation, and all collection efforts are exhausted. The following table presents the changes in the allowance for doubtful accounts (in thousands): | |||||||||||||||||

Warranties and Indemnification | Warranties and Indemnification | ||||||||||||||||
Our cloud-based service to automate enterprise service operations is typically warranted to perform in material conformance with specifications. | |||||||||||||||||
We include service level commitments to our customers that permit those customers to receive credits in the event we fail to meet those levels. We establish an accrual based on historical credits paid and an evaluation of the performance of our services including an assessment of the impact, if any, of any known service disruptions. Service level credit accrual charges are recorded against revenue. The following table presents the changes in the service level credit accrual (in thousands): | |||||||||||||||||

Service level credit accrual | $ | 1,196 | 430 | 978 | $ | 648 | |||||||||||
We have also agreed to indemnify our directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by us, arising out of that person’s services as a director or officer of our company or that person’s services provided to any other company or enterprise at our request. We maintain director and officer insurance coverage that may enable us to recover a portion of any future amounts paid. The fair values of these obligations are not material as of each balance sheet date. | |||||||||||||||||
Our arrangements include provisions indemnifying customers against intellectual property and other third-party claims. We have not incurred any costs as a result of such indemnifications and have not recorded any liabilities related to such obligations in the consolidated financial statements. | |||||||||||||||||
Income Taxes | Income Taxes | ||||||||||||||||
We use the asset and liability method of accounting for income taxes, in which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed. We recognize the effect on deferred tax assets and liabilities of a change in tax rates as income and expense in the period that includes the enactment date. A valuation allowance is established if it is more likely than not that all or a portion of the deferred tax asset will not be realized. In determining the need for a valuation allowance, we consider future growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate, historical earnings, taxable income in prior years, if carryback is permitted under the law, carry-forward periods, and prudent and feasible tax planning strategies. | |||||||||||||||||
Our tax positions are subject to income tax audits by multiple tax jurisdictions throughout the world. We recognize the tax benefit of an uncertain tax position only if it is more likely than not the position is sustainable upon examination by the taxing authority, based on the technical merits. We measure the tax benefit recognized as the largest amount of benefit which is more likely than not to be realized upon settlement with the taxing authority. We recognize interest accrued and penalties related to unrecognized tax benefits in our tax provision. | |||||||||||||||||
We calculate the current and deferred income tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed in subsequent years and record adjustments based on filed income tax returns when identified. The amount of income taxes paid is subject to examination by U.S. federal, state and foreign tax authorities. The estimate of the potential outcome of any uncertain tax issue is subject to management’s assessment of relevant risks, facts and circumstances existing at that time. To the extent the assessment of such tax position changes, we record the change in estimate in the period in which we make the determination. | |||||||||||||||||
Recent Accounting Pronouncements | Recent Accounting Pronouncements | ||||||||||||||||
In May 2014, the Financial Accounting Standards Board, or FASB, issued an update to ASC 606 Revenue from Contracts with Customers, or ASC 606, that will supersede virtually all existing revenue guidance. Under this update, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This update should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. This guidance will become effective for us for our interim and annual reporting periods beginning January 1, 2017. We are currently evaluating the impact of this update on our consolidated financial statements. |
