Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements, which include the accounts of Nutanix, Inc. and its wholly-owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation. These reclassifications had no impact on the previously reported net loss or accumulated deficit. Effective August 1, 2017, we adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASC 606"), as discussed in detail in Note 3. All amounts and disclosures set forth in this Annual Report on Form 10-K have been updated to comply with ASC 606, as indicated by the "as adjusted" note. Certain prior period amounts have been adjusted as a result of our adoption of ASC 606. Refer to "Recently Adopted Accounting Pronouncements" below for more information.
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Such management estimates include, but are not limited to, the best estimate of selling prices for products and related support; useful lives of intangible assets and property and equipment; allowance for doubtful accounts; determination of fair value of common stock and convertible preferred stock, fair value of stock-based awards and convertible preferred stock warrant liability; accounting for income taxes, including the valuation allowance on deferred tax assets and uncertain tax positions; warranty liability; fair value of contingent consideration in a business combination; sales commissions expense; and contingencies and litigation. Management evaluates these estimates and assumptions on an ongoing basis using historical experience and other factors and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions.
Concentration Risk | Concentration Risk Credit Risk—Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. We invest only in high-quality credit instruments and maintain our cash and cash equivalents and available-for-sale investments in fixed income securities. Management believes that the financial institutions that hold our investments are financially sound and, accordingly, are subject to minimal credit risk. Our deposits are with multiple institutions, however such deposits may exceed federally insured limits. We provide credit, in the normal course of business, to a number of companies and perform credit evaluations of our customers. Concentration of Revenue and Accounts Receivable — We sell our products primarily through Partners and occasionally directly to end customers. Vendor Risk — We rely on a limited number of suppliers for our contract manufacturing and certain raw material components. In instances where suppliers fail to perform their obligations, we may be unable to find alternative suppliers or satisfactorily deliver our products to our customers on time.
Cash, Cash Equivalents | Cash, Cash Equivalents and Short-Term Investments We classify all highly liquid investments with original maturities of three months or less from the date of purchase as cash equivalents and all highly liquid investments with stated maturities of greater than three months as marketable securities.
Short-Term Investments | We determine the appropriate classification of our marketable securities at the time of purchase and reevaluate such designation as of each balance sheet date. We classify and account for our marketable securities as available-for-sale securities. We classify our marketable securities with stated maturities greater than twelve months as short-term investments due to our intent and ability to use these securities to support our current operations. Our marketable securities are recorded at their estimated fair value. Unrealized gains or losses on available-for-sale securities are reported in other comprehensive income (loss). We periodically review whether our securities may be other-than-temporarily impaired, including whether or not (i) we have the intent to sell the security or (ii) it is more likely than not that we will be required to sell the security before its anticipated recovery. If one of these factors is met, we will record an impairment loss associated with our impaired investment. The impairment loss will be recorded as a write-down of investments in the consolidated balance sheets and a realized loss within other expense in the consolidated statements of operations.
Fair Value Measurement | Fair Value Measurement We define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to their short-term nature. The fair value of the Notes is determined based on the closing trading price per $100 of the Notes as of the last day of trading for the period.
Accounts Receivable and Allowance for Doubtful Accounts | Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount, net of an allowance for doubtful accounts. Credit is extended to customers based on an evaluation of their financial condition and other factors. We generally do not require collateral or other security to support accounts receivable. We perform ongoing credit evaluations of our customers and maintain an allowance for doubtful accounts. The allowance for doubtful accounts is based on the best estimate of the amount of probable credit losses in existing accounts receivable. We evaluate the collectability of our accounts receivable based on known collection risks and historical experience. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations (e.g., bankruptcy filings or substantial downgrading of credit ratings), we record an allowance for doubtful accounts in order to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we record an allowance for doubtful accounts based on the length of time the receivable is past due and our historical experience of collections and write-offs.
Property and Equipment | Property and Equipment Property and equipment, including leasehold improvements, are stated at cost, less accumulated depreciation and amortization. We include the cost to acquire demonstration units and the related accumulated depreciation in property and equipment as such units are generally not available for sale. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets.
Business Combination | Business Combinations We account for our acquisitions using the acquisition method. Goodwill is measured at the acquisition date as the excess of the purchase price over the fair value of the assets acquired and liabilities assumed. Significant estimates and assumptions are made by management to value such assets and liabilities. Although we believe that those estimates and assumptions are reasonable and appropriate, they are inherently uncertain and subject to refinement. Additional information related to the acquisition date fair value of acquired assets and assumed liabilities obtained during the measurement period, not to exceed one year, may result in changes to the recorded values of such assets and liabilities, resulting in an offsetting adjustment to the goodwill associated with the business acquired. Uncertain tax positions and tax-related valuation allowances are initially established in connection with a business combination as of the acquisition date. We continue to collect information and reevaluate these estimates and assumptions quarterly. We will record any adjustments to our preliminary estimates to goodwill, provided that it is within the one-year measurement period. Any contingent consideration payable is recognized at fair value at the acquisition date. Liability-classified contingent consideration is remeasured each reporting period, with changes in fair value recognized in earnings until the contingent consideration is settled. Acquisition related costs incurred in connection with a business combination, other than those associated with the issuance of debt or equity securities, are expensed as incurred.
Impairment of Long-Lived Assets | Goodwill, Intangible Assets and Other Long-Lived Assets Goodwill represents the future economic benefits arising from other assets acquired in a business combination or an acquisition that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. Intangible assets consist of identifiable intangible assets, including developed technology, customer relationships and in-process research and development ("IPR&D"), resulting from business combinations. Finite-lived intangible assets are recorded at fair value, net of accumulated amortization. Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives. Amortization expense is included as a component of cost of product revenue and sales and marketing expense in the accompanying consolidated statements of operations. Amounts included in sales and marketing expense relate to customer relationships. Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life, such as IPR&D, are not amortized, but instead tested for impairment at least annually, as of May 1 of each year. Such goodwill and other intangible assets may also be tested for impairment between annual tests in the presence of impairment indicators such as, but not limited to: (i) a significant adverse change in legal factors or in the business climate; (ii) a substantial decline in our market capitalization; (iii) an adverse action or assessment by a regulator; (iv) unanticipated competition; (v) loss of key personnel; (vi) a more likely-than-not expectation of the sale or disposal of a reporting unit or a significant portion thereof; (vii) a realignment of our resources or restructuring of our existing businesses in response to changes to industry and market conditions; (viii) testing for recoverability of a significant asset group within a reporting unit; or (ix) a higher discount rate used in the impairment analysis as impacted by an increase in interest rates. Goodwill is tested for impairment by comparing the reporting unit's carrying value, including goodwill, to the fair value of the reporting unit. We operate under one reporting unit and for our annual goodwill impairment test, we determine the fair value of our reporting unit based on our enterprise value. We may elect to utilize a qualitative assessment to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying value. If, after assessing the qualitative factors, we determine that it is more likely than not that the fair value of our reporting unit is less than its carrying value, an impairment analysis will be performed. We compare the fair value of our reporting unit with its carrying amount and if the carrying value of the reporting unit exceeds its fair value, an impairment loss will be recognized. Long-lived assets, such as property and equipment and finite-lived intangible assets subject to depreciation and amortization, are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Among the factors and circumstances we consider in determining recoverability are: (i) a significant decrease in the market price of a long-lived asset; (ii) a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; (iii) a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, including an adverse action or assessment by a regulator; (iv) an accumulation of costs significantly in excess of the amount originally expected for the acquisition; and (v) current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Revenue Recognition | Revenue Recognition Effective August 1, 2017, we adopted ASC 606 using the full retrospective method. Refer to Note 3 for a detailed discussion of accounting policies related to revenue recognition, including deferred revenue and commissions. Cost of Revenue Cost of revenue consists of cost of product revenue and cost of support, entitlements and other services revenue. Personnel costs associated with our operations and global customer support organizations consist of salaries, benefits and stock-based compensation. Allocated costs consist of certain facilities, depreciation and amortization, recruiting, and information technology costs allocated based on headcount. Revenue Recognition Effective August 1, 2017, we adopted ASC 606 using the full retrospective method, which required a recast of historical financial information to conform with the standard. The most significant impact of ASC 606 on our historical financial information relates to the timing of revenue recognition for certain software licenses sold with PCS, for which we did not have vendor specific objective evidence ("VSOE") of fair value under the previous revenue recognition guidance. Under ASC 606, the requirement to have VSOE for undelivered elements was eliminated and we now recognize revenue for such software licenses upon transfer of control to the customer. In addition, the adoption of ASC 606 also resulted in differences in the timing of recognition of contract costs, such as sales commissions, as well as the corresponding impact to the provision for income taxes. The adoption of the standard had no significant impact on the provision for income taxes and had no impact on the net cash from or used in operating, investing or financing activities on the consolidated statements of cash flows. See "ASC 606 Adoption Impact to Previously Reported Results" below for the impact of the adoption of the standard on the consolidated financial statements.
Warranties | Warranties We generally provide a one-year warranty on hardware and a 90-day warranty on software licenses. The hardware warranty provides for parts replacement for defective components and the software warranty provides for bug fixes. With respect to the hardware warranty obligation, we have a warranty agreement with our contract manufacturers under which the contract manufacturers are generally required to replace defective hardware within three years of shipment. Furthermore, our post-contract customer support ("PCS") agreements provide for the same parts replacement that customers are entitled to under the warranty program, except that replacement parts are delivered according to targeted response times to minimize disruption to the customers’ critical business applications. Substantially all customers purchase PCS agreements. Given the warranty agreement with our contract manufacturers and considering that substantially all products are sold together with PCS agreements, we generally have very limited exposure related to warranty costs and therefore no warranty reserve has been recognized.
Research and Development | Research and Development Our research and development expense consists primarily of product development personnel costs, including salaries and benefits, stock-based compensation and allocated facilities costs. Research and development costs are expensed as incurred.
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense is measured based on the grant date fair value of share-based awards. The fair value of the stock options and purchase rights issued to employees under our 2016 Employee Stock Purchase Plan ("2016 ESPP") is estimated using the Black-Scholes-Merton ("Black-Scholes") option pricing model, which is impacted by the fair value of our common stock, as well as changes in assumptions regarding a number of subjective variables. These variables include the expected common stock price volatility over the term of the awards, the expected term of the awards, risk-free interest rates and expected dividend yield. We grant stock awards with service conditions only and with both service and performance conditions. We recognize stock-based compensation expense for employee stock awards with a service condition only using the straight-line method over the requisite service period of the awards, which is generally the vesting period. We use the accelerated attribution method to recognize stock-based compensation expense related to employee stock awards that contain both service and performance conditions. The fair value of the 2016 ESPP purchase rights is recognized as expense on a straight-line basis over the offering period. We account for forfeitures of all share-based awards when they occur. We determine the fair value of stock awards issued to nonemployees on the date of grant, utilizing the Black-Scholes option pricing model. Stock-based compensation expense for stock awards issued to nonemployees is recognized over the requisite service period or when it is probable that the performance condition will be satisfied. Nonemployee awards subject to vesting are periodically remeasured to current fair value over the vesting period.
Foreign Currency | Foreign Currency The functional currency of our foreign subsidiaries is the U.S. dollar. Transactions denominated in currencies other than the functional currency are remeasured at the average exchange rate in effect during the reporting period. At the end of each reporting period all monetary assets and liabilities of our subsidiaries are remeasured at the current U.S. dollar exchange rate at the end of the reporting period. Remeasurement gains and losses are included within other expense, net in the accompanying consolidated statements of operations.
Income Taxes | Income Taxes We account for income taxes using the asset and liability method. Deferred income taxes are recognized by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance on amounts that are more likely than not to be realized. We record a liability for uncertain tax positions if it is not more likely than not to be sustained based solely on its technical merits as of the reporting date. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes.
Advertising Costs | Advertising Costs Advertising costs are charged to sales and marketing expenses as incurred in the consolidated statements of operations.
Recently Issued and Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued ASC 606. The standard is a comprehensive new revenue recognition model that requires revenue to be recognized in a manner which depicts the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The FASB has issued several amendments to the standard, including clarifications on the disclosure of prior period performance obligations and remaining performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The new standard would have been effective for us beginning August 1, 2018, but early adoption as of the original effective date of August 1, 2017 was also permitted. We elected to early adopt the standard effective August 1, 2017 using the full retrospective method, which required a recast historical financial information to conform with the new standard. Refer to Note 3 for details of the impact to previously reported results. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments, with further clarifications made recently with the issuance of ASU 2018-03 and 2018-04. These new standards require equity securities to be measured at fair value, with changes in fair value recognized through net income, which results in greater variability in our net income. We adopted the standard on January 1, 2018 and it did not have any impact on the consolidated financial statements, since other than our investments in money market funds, which are reported as part of cash and cash equivalents, we do not have any other investments that are classified as equity securities. There are no unrealized gains or losses related to our investments in money market funds, as the fair value is equal to the face value. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This new standard will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. We adopted this ASU effective November 1, 2017 and our adoption did not have any impact on the consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), to clarify the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We adopted this ASU effective August 1, 2017 and our adoption did not have a material impact on the consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The guidance is effective for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. We adopted this ASU effective August 1, 2017 and our adoption did not have a material impact on the consolidated financial statements. Recently Issued and Not Yet Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, which requires recognition of right-to-use lease assets and lease liabilities for all leases, except for short-term leases, on the balance sheet of lessees. ASU 2016-02 is effective for us beginning August 1, 2019, with early adoption permitted. This new standard requires a modified retrospective transition approach and provides certain optional transition relief. We currently anticipate that the adoption of this standard will have a material impact on our consolidated balance sheets, given that we had operating lease commitments in excess of $100 million as of July 31, 2018. We expect that most of our operating lease commitments will be subject to the new standard and recognized as lease liabilities and right-of-use assets upon adoption, which will increase the total assets and total liabilities reported. However, we do not anticipate that the adoption of this standard will have a material impact on our consolidated statements of operations, as the expense recognition under this new standard will be similar to current practice. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This new standard will require us to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for us beginning August 1, 2018, with early adoption permitted. We will adopt this standard in the first quarter of fiscal 2019 and anticipate an increase in deferred tax assets, which will be offset by a valuation allowance, thus resulting in an immaterial net impact to our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This new standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period amounts shown on the statement of cash flows. ASU 2016-18 is effective for us beginning August 1, 2018, with early adoption permitted. We do not believe that the adoption of this ASU will have a material impact on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which aligns the accounting for share-based payment awards issued to nonemployees with the guidance applicable to grants to employees. Under the new standard, equity-classified share-based payment awards issued to nonemployees will be measured on the grant date, instead of the current requirement to remeasure the awards through the performance completion date. ASU 2018-07 is effective for us beginning August 1, 2019, with early adoption permitted. We do not believe that the adoption of this ASU will have a material impact on our consolidated financial statements.
