[1]	During the first quarter of fiscal 2019, we adopted Accounting Standards Update ("ASU") No. 2016-18, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and restricted cash. We adopted the standard retrospectively for the prior period presented. Our adoption of ASU 2016-18 did not have any significant impact on our condensed consolidated statements of cash flows.

Accounting Policies [Abstract]
OVERVIEW AND BASIS OF PRESENTATION	OVERVIEW AND BASIS OF PRESENTATION Organization and Description of Business Nutanix, Inc. was incorporated in the state of Delaware in September 2009. Nutanix, Inc. is headquartered in San Jose, California, and together with its wholly-owned subsidiaries (collectively, "we," "us," "our" or "Nutanix") has operations throughout North America, Europe, Asia Pacific, the Middle East, Latin America and Africa. We provide a leading enterprise cloud platform that digitizes the traditional silos of enterprise computing, converging compute, virtualization, storage, networking, desktop, governance and security services into one integrated solution. We primarily sell our products and services to end customers through distributors, resellers and original equipment manufacturers ("OEMs") (collectively, "Partners"). Principles of Consolidation and Significant Accounting Policies The accompanying condensed 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") and are consistent in all material respects with those included in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018 , filed with the Securities and Exchange Commission ("SEC") on September 24, 2018. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements are unaudited, but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. 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. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018 . Use of Estimates The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed 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 stock-based awards; 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 of Risk Concentration of revenue and accounts receivable —We sell our products primarily through our Partners and occasionally directly to end customers. For the three and nine months ended April 30, 2018 and 2019 , no end customer accounted for more than 10% of total revenue or accounts receivable. For each significant Partner, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable, net are as follows: Revenue Accounts Receivable as of Three Months Ended Nine Months Ended Partners 2018 2019 2018 2019 July 31, 2018 April 30, 2019 Partner A (1) (1) 10 % 10 % 16 % (1) Partner B 15 % 10 % 20 % 11 % 13 % (1) Partner C 18 % 26 % 17 % 23 % 15 % 25 % Partner D (1) (1) 10 % (1) (1) (1) Partner E 13 % 13 % 13 % 12 % 12 % 13 % (1) Less than 10% Summary of Significant Accounting Policies There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018 , filed with the SEC on September 24, 2018, that have had a material impact on our condensed consolidated financial statements and related notes. Recently Adopted Accounting Pronouncements In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires us to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted this ASU effective August 1, 2018 using a modified retrospective approach. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which 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. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted the new standard effective August 1, 2018, using the retrospective transition approach. The reclassified restricted cash balances from operating activities to changes in cash, cash equivalents and restricted cash on the condensed consolidated statements of cash flows were not material for any period presented. 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. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software, which standard aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a significant impact on our condensed consolidated financial statements. In August 2018, the SEC issued Securities Act Release No. 33-10532, which amends certain disclosure requirements, including extending to interim periods the annual requirement to disclose changes in stockholders’ equity. Under the new requirements, registrants must now analyze changes in stockholders’ equity, in the form of a reconciliation, for the current and comparative year-to-date interim periods, with subtotals for each interim period. The final rule was effective in November 2018. We adopted this new guidance during the first quarter of fiscal 2019 and have included a reconciliation of the changes in stockholders' equity in this Quarterly Report on Form 10-Q. Recently Issued and Not Yet Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, which requires the recognition of right-of-use lease assets and lease liabilities for all leases, except for short-term leases, on the condensed consolidated balance sheets of lessees. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We will adopt the standard effective August 1, 2019 and we intend to elect certain practical expedients, including the transition option that will allow us to not have to restate the comparative periods in our condensed consolidated financial statements in the year of adoption. We currently anticipate that the adoption of this standard will have a material impact on our condensed consolidated balance sheets, given that we had operating lease commitments in excess of $175 million as of April 30, 2019 , on an undiscounted basis. We expect that most of our operating lease commitments will be subject to the new standard and will be recognized as lease liabilities and right-of-use assets upon adoption, which will increase our total assets and total liabilities reported. However, we do not anticipate that the adoption of this standard will have a material impact on our condensed consolidated statements of operations, as the expense recognition under the new standard will be similar to current practice. We do not expect the adoption of this standard to have a material impact on our condensed consolidated statements of cash flows. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which provides companies with an option to reclassify stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act ("TCJA") from accumulated other comprehensive income to retained earnings. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years, and will be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax rate as a result of TCJA is recognized. We have not made a determination as to which alternative method we will use upon adoption of the standard, but we do not expect the adoption of this ASU to have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of the FASB's disclosure framework project. The new standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including interim reporting periods within those fiscal years. We do not expect the adoption of this ASU to have a significant impact on our quarterly or annual disclosures.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATION Mainframe2, Inc. On August 24, 2018, we completed the acquisition of Mainframe2, Inc. ("Frame"), a privately held Delaware corporation with its principal offices in San Mateo, California ("Frame Acquisition"). Frame provides a cloud-based Windows desktop and application delivery service. The aggregate preliminary purchase price of approximately $130.0 million consisted of approximately $26.7 million in cash and 1,813,321 shares of our Class A common stock, with an aggregate fair value of approximately $103.3 million . The fair value of the shares of common stock issued was determined to be $56.97 per share, the closing price of our stock on August 24, 2018. Certain portions of the consideration for the acquisition, both cash and shares of our Class A common stock, have been placed in escrow to secure the indemnification obligations of certain Frame security holders. We also entered into employee holdback or deferred payment arrangements with certain employees of Frame who joined Nutanix after the acquisition, totaling approximately $43.3 million , of which $6.6 million will be paid in cash ("cash holdback") and $36.7 million will be satisfied by issuing shares of our Class A common stock ("share holdback"). As the earning of the share holdback and payment of the cash holdback are contingent upon the continuous service of the employees, they are being accounted for as post-combination compensation expense over the required service period of three years . The 643,746 shares of our Class A common stock related to the $36.7 million share holdback have a fair value of $56.97 per share, the closing price of our Class A common stock on August 24, 2018, and had been issued at closing and are currently being held in escrow. This holdback is being accounted for as stock-based compensation over the required three -year service period. On September 21, 2018, we filed a Form S-3 registration statement with the SEC for the 2,451,322 shares of our Class A common stock that were issued as partial consideration in the Frame Acquisition. Acquisition-related costs are expensed as incurred as general and administrative expenses on our condensed consolidated statement of operations. We incurred approximately $1.1 million of acquisition-related costs in connection with the Frame Acquisition, of which approximately $0.4 million was recognized during the nine months ended April 30, 2019 . The following table presents the preliminary aggregate purchase price allocation related to our acquisition of Frame as of April 30, 2019 : Estimated Fair Value (in thousands) Goodwill $ 97,328 Amortizable intangible assets 38,180 Tangible assets acquired 10,811 Liabilities assumed (16,293 ) Total consideration $ 130,026 The $38.2 million of amortizable intangible assets includes $31.8 million related to developed technology and $2.2 million related to customer relationships, which will be amortized over an estimated economic life of five years , and $4.2 million related to trade name, which will be amortized over an estimated economic life of four years . Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The goodwill recognized in this acquisition is primarily attributable to the synergies expected from the expanded market opportunities with our offerings and the knowledgeable and experienced workforce that joined us as part of the acquisition. Goodwill will not be amortized, but will instead be tested for impairment annually or more frequently if certain indicators of impairment are present. Goodwill is not expected to be deductible for income tax purposes. The purchase price allocation for Frame reflects various preliminary fair value estimates and analyses, including certain tangible assets acquired and liabilities assumed, the valuation of intangible assets acquired, income taxes and goodwill, which are subject to change within the measurement period as preliminary valuations are finalized. Measurement period adjustments are recorded in the reporting period in which the estimates are finalized and adjustment amounts are determined. We determined the fair values of the intangible assets with the assistance of a valuation firm. The estimation of the fair value of the intangible assets required the use of valuation techniques and entailed consideration of all the relevant factors that might affect the fair value, such as present value factors and estimates of future revenues and costs. Our condensed consolidated financial statements for the three and nine months ended April 30, 2019

REVENUE, DEFERRED REVENUE AND D

REVENUE, DEFERRED REVENUE AND DEFERRED COMMISSIONS	9 Months Ended

Revenue Recognition and Deferred Revenue [Abstract]
REVENUE, DEFERRED REVENUE AND DEFERRED COMMISSIONS	ue and Revenue Recognition We generate revenue primarily from the sale of our enterprise cloud platform, which can be delivered pre-installed on an appliance that is configured to order or delivered separately to be utilized on a variety of certified hardware platforms. Software delivered on configured to order appliances is not portable to other appliances and has a term equal to the life of the associated appliance, while subscription term-based licenses typically have a term of one to five years . Configured to order appliances, including our Nutanix-branded NX hardware line, are typically sold through Partners and can be purchased from one of our OEMs or directly from Nutanix. Our platform is typically purchased with one or more years of support and entitlements, which includes the right to software upgrades and enhancements as well as technical support. A substantial portion of sales are made through channel partners and OEM relationships. The following table depicts the disaggregation of revenue by revenue type, consistent with how we evaluate our financial performance: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands) Subscription $ 80,105 $ 168,447 $ 216,668 $ 452,779 Non-portable software 140,879 88,719 396,986 366,910 Hardware 62,617 21,853 221,454 92,319 Professional services 5,812 8,605 16,601 24,259 Total revenue $ 289,413 $ 287,624 $ 851,709 $ 936,267 Prior to the first quarter of fiscal 2019, we disaggregated revenue into the following categories: software revenue, hardware revenue and support, entitlements and other services revenue. Software revenue included non-portable software and term-based software licenses. Under the new disaggregated revenue categories, included in the table above, term-based software licenses are included within subscription revenue and non-portable software is presented separately. Support, entitlements and other services revenue included software entitlement and support subscriptions and professional services. Under the new disaggregated revenue categories, software entitlement and support subscriptions are included within subscription revenue and professional services revenue is presented separately. There was no change to the presentation of hardware revenue. Subscription revenue — Subscription revenue is generated from the sales of software entitlement and support subscriptions, subscription term-based licenses and cloud-based software as a service ("SaaS") offerings. We recognize revenue from software entitlement and support subscriptions and SaaS offerings ratably over the contractual service period, the majority of which relate to software entitlement and support subscriptions. These offerings represented approximately $62.5 million and $171.8 million of our subscription revenue for the three and nine months ended April 30, 2018 and approximately $96.1 million and $269.7 million of our subscription revenue for the three and nine months ended April 30, 2019 , respectively. Revenue from our subscription term-based licenses is generally recognized upfront upon transfer of control to the customer, which happens when we make the software available to the customer. These subscription term-based licenses represented approximately $17.6 million and $44.9 million of our subscription revenue for the three and nine months ended April 30, 2018 and approximately $72.3 million and $183.1 million of our subscription revenue for the three and nine months ended April 30, 2019 , respectively. For the three and nine months ended April 30, 2018 , the weighted average term for these subscription term-based licenses was approximately 3.3 years and 3.6 years , respectively. For the three and nine months ended April 30, 2019 , the weighted average term for these subscription term-based licenses was approximately 3.9 years and 3.8 years , respectively. Non-portable software revenue — Non-portable software revenue includes sales of our software operating system when delivered on a configured to order appliance by us or one of our OEMs. The software licenses associated with these sales are typically non-portable and have a term equal to the life of the appliance the software is delivered on. Revenue from our non-portable software products is generally recognized upon transfer of control to the customer. Hardware revenue — In transactions where we deliver the hardware appliance, we consider ourselves to be the principal in the transaction and we record revenue and costs of goods sold on a gross basis. We consider the amount allocated to hardware revenue to be equivalent to the cost of the hardware procured. Hardware revenue is generally recognized upon transfer of control to the customer. Professional services revenue — We also sell professional services with our products. We recognize revenue related to professional services as they are performed. Contracts with multiple performance obligations — Some of our contracts with customers contain multiple performance obligations. For these contracts, we account for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price ("SSP") basis. For deliverables that we routinely sell separately, such as software entitlement and support subscriptions on our core offerings, we determine SSP by evaluating the standalone sales over the trailing 12 months. For those that are not sold routinely, we determine SSP based on our overall pricing trends and objectives, taking into consideration market conditions and other factors, including the value of our contracts, the products sold and geographic locations. Contract balances — The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable are recorded at the invoiced amount, net of an allowance for doubtful accounts. A receivable is recognized in the period we deliver goods or provide services, or when our right to consideration is unconditional. In situations where revenue recognition occurs before invoicing, an unbilled receivable is created, which represents a contract asset. Unbilled accounts receivable, included in accounts receivable, net on the condensed consolidated balance sheets, was not material for any of the periods presented. Payment terms on invoiced amounts are typically 30 days. The balance of accounts receivable, net of allowance for doubtful accounts, as of July 31, 2018 and April 30, 2019 is presented in the accompanying condensed consolidated balance sheets. Costs to obtain and fulfill a contract — We capitalize commissions paid to sales personnel and the related payroll taxes when customer contracts are signed. These costs are recorded as deferred commissions in the condensed consolidated balance sheets, current and non-current. We determine whether costs should be deferred based on our sales compensation plans, if the commissions are incremental and would not have been incurred absent the execution of the customer contract. Sales commissions for renewals of customer support subscriptions are not commensurate with the commissions paid for the acquisition of the initial contract given the substantive difference in commission rates in proportion to their respective contract values. Commissions paid upon the initial acquisition of a contract are amortized over the estimated period of benefit, which may exceed the term of the initial contract. Accordingly, the amortization of deferred costs is recognized on a systematic basis that is consistent with the pattern of revenue recognition allocated to each performance obligation and included in sales and marketing expense in the condensed consolidated statements of operations. We determine the estimated period of benefit by evaluating the expected renewals of customer contracts, the duration of relationships with our customers, customer retention data, our technology development lifecycle and other factors. Deferred costs are periodically reviewed for impairment. Deferred revenue — Deferred revenue primarily consists of amounts that have been invoiced but not yet recognized as revenue and primarily pertain to support subscriptions and professional services. The current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the condensed consolidated balance sheet date. Significant changes in the balance of deferred revenue (contract liability) and total deferred commissions (contract asset) for the periods presented are as follows: Deferred Revenue Deferred Commissions (in thousands) Balance as of July 31, 2018 $ 631,207 $ 114,379 Additions 159,210 33,958 Revenue/commissions recognized (88,937 ) (26,230 ) Assumed in a business combination 320 — Balance as of October 31, 2018 701,800 122,107 Additions 176,487 37,280 Revenue/commissions recognized (98,428 ) (29,353 ) Balance as of January 31, 2019 779,859 130,034 Additions 161,233 38,396 Revenue/commissions recognized (102,830 ) (29,232 ) Balance as of April 30, 2019 $ 838,262 $ 139,198 During the three and nine months ended April 30, 2018 , we recognized revenue of approximately $49.4 million and $136.8 million pertaining to amounts deferred as of January 31, 2018 and July 31, 2017 , respectively. During the three and nine months ended April 30, 2019 , we recognized revenue of approximately $89.8 million and $216.3 million pertaining to amounts deferred as of January 31, 2019 and July 31, 2018 , respectively. The majority of our contracted but not invoiced performance obligations are subject to cancellation terms. Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized ("contracted not recognized"), which includes deferred revenue and non-cancelable amounts that will be invoiced and recognized as revenue in future periods and excludes performance obligations that are subject to cancellation terms. Contracted not recognized revenue was approximately $845.7 million as of April 30, 2019 , of which we expect to recognize approximately 43%

Financial instruments that are not recorded at fair value are measured at fair value on a quarterly basis for disclosure purposes. The carrying values and estimated fair values of financial instruments not recorded at fair value are as follows: As of July 31, 2018 As of April 30, 2019 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value (in thousands) Convertible senior notes, net $ 429,598 $ 685,527 $ 451,399 $ 657,921 The carrying value of the Notes as of April 30, 2019 was net of the unamortized debt discount of $117.1 million and unamortized debt issuance costs of $6.5 million . The total estimated fair value of the Notes was determined based on the closing trading price per $100 of the Notes as of the last day of trading for the period. We consider the fair value of the Notes to be a Level 2 measurement due to the limited trading activity. A summary of the changes in the fair value of our contingent consideration, characterized as Level 3 in the fair value hierarchy, is as follows: Nine Months Ended 2018 2019 (in thousands) Contingent consideration—beginning balance $ 4,295 $ 1,872 Change in fair value (1) (3,371 ) (832 ) Payment — (1,040 ) Contingent consideration—ending balance $ 924 $ — (1) Recognized in the condensed consolidated statements of operations within general and administrative expenses. We remeasured the fair value of our Level 3 contingent consideration liability using a Monte Carlo simulation on projected future payments. The fair value was determined by calculating the net present value of the expected payments using significant inputs that were not observable in the market, including the probability of achieving the milestone, estimated bookings and discount rates. The change in fair value of the contingent consideration was due to the movement of the inputs. During the quarter ended April 30, 2019 , the contingent consideration was paid out in full.

BALANCE SHEET COMPONENTS	BALANCE SHEET COMPONENTS Short-Term Investments The amortized cost of our short-term investments approximates their fair value. As of July 31, 2018 and April 30, 2019 , unrealized gains and losses from our short-term investments were not material. As of July 31, 2018 and April 30, 2019 , unrealized losses from securities that were in an unrealized loss position for more than 12 months were not material. Unrealized losses related to our short-term investments are due to interest rate fluctuations, as opposed to credit quality. In addition, unless we need cash to support our current operations, we do not intend to sell and it is not likely that we would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. As a result, at July 31, 2018 and April 30, 2019 , there were no other-than-temporary impairments for these investments. The following table summarizes the estimated fair value of our investments in marketable debt securities by their contractual maturity dates: As of April 30, 2019 (in thousands) Due within one year $ 373,305 Due in one to two years 122,328 Total $ 495,633 Property and Equipment, Net Property and equipment, net consists of the following: Estimated As of July 31, 2018 April 30, 2019 (in months) (in thousands) Computer, production, engineering and other equipment 36 $ 131,805 $ 187,380 Demonstration units 12 53,547 59,254 Leasehold improvements (1) 19,916 42,862 Furniture and fixtures 60 7,636 13,051 Total property and equipment, gross 212,904 302,547 Less: accumulated depreciation (127,793 ) (167,985 ) Total property and equipment, net $ 85,111 $ 134,562 (1) Leasehold improvements are amortized over the shorter of the estimated useful lives of the improvements or the remaining lease term. Depreciation expense related to our property and equipment was $11.3 million and $31.9 million for the three and nine months ended April 30, 2018 and $16.4 million and $43.3 million for the three and nine months ended April 30, 2019 , respectively. Goodwill and Intangible Assets, Net The changes in the carrying value of goodwill during the nine months ended April 30, 2019 were as follows: Carrying Amount (in thousands) Balance as of July 31, 2018 $ 87,759 Acquired in Frame Acquisition 97,328 Other 93 Balance as of April 30, 2019 $ 185,180 Intangible assets, net consists of the following: As of July 31, 2018 April 30, 2019 (in thousands) Developed technology $ 47,500 $ 79,300 Customer relationships 6,650 8,860 Trade name — 4,170 Total intangible assets, gross 54,150 92,330 Less: Accumulated amortization of developed technology (6,956 ) (17,515 ) Accumulated amortization of customer relationships (1,828 ) (3,002 ) Accumulated amortization of trade name — (695 ) Total accumulated amortization (8,784 ) (21,212 ) Total intangible assets, net $ 45,366 $ 71,118 Amortization expense related to our intangible assets is being recognized in the condensed consolidated statements of operations within product cost of revenue for developed technology and sales and marketing expense for customer relationships and trade name.

Debt Disclosure [Abstract]
CONVERTIBLE SENIOR NOTES	CONVERTIBLE SENIOR NOTES In January 2018, we issued Convertible Senior Notes with a 0% interest rate for an aggregate principal amount of $575.0 million , due in 2023 (the "Notes"), in a private placement to qualified institutional buyers pursuant to Rule144A under the Securities Act of 1933, as amended. This included $75.0 million in aggregate principal amount of the Notes that we issued resulting from initial purchasers fully exercising their option to purchase additional notes. There are no required principal payments prior to the maturity of the Notes. The total net proceeds from the Notes are as follows: Amount (in thousands) Principal amount $ 575,000 Less: initial purchasers' discount (10,781 ) Less: cost of the bond hedges (143,175 ) Add: proceeds from the sale of warrants 87,975 Less: other issuance costs (707 ) Net proceeds $ 508,312 The Notes do not bear any interest and will mature on January 15, 2023, unless earlier converted or repurchased in accordance with their terms. The Notes are unsecured and do not contain any financial covenants or any restrictions on the payment of dividends, or the issuance or repurchase of securities by us. Each $1,000 of principal of the Notes will initially be convertible into 20.4705 shares of our Class A common stock, which is equivalent to an initial conversion price of approximately $48.85 per share, subject to adjustment upon the occurrence of specified events. Holders of these Notes may convert their Notes at their option at any time prior to the close of the business day immediately preceding October 15, 2022, only under the following circumstances: 1) during any fiscal quarter commencing after the fiscal quarter ending on April 30, 2018 (and only during such fiscal quarter), if the last reported sale price of our Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter, is greater than or equal to 130% of the conversion price on each applicable trading day; 2) 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 Class A common stock and the conversion rate for the Notes on each such trading day; or 3) upon the occurrence of certain specified corporate events. Based on the closing price of our Class A common stock of $43.19 on April 30, 2019 , the if-converted value of the Notes was lower than the principal amount. The price of our Class A common stock was not greater than or equal to 130% of the conversion price for 20 or more trading days during the 30 consecutive trading days ending on the last trading day of the quarter ended April 30, 2019 , the Notes are not convertible for the fiscal quarter commencing after April 30, 2019 . On or after October 15, 2022, holders may convert all or any portion of their 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 of the Notes, we will pay or deliver, as the case may be, cash, shares of our Class A common stock or a combination of cash and shares of Class A common stock, at our election. We intend to settle the principal of the Notes in cash. The conversion rate will be subject to adjustment in some events, but will not be adjusted for any accrued or unpaid interest. A holder who converts their Notes in connection with certain corporate events that constitute a "make-whole fundamental change" per the indenture governing the Notes are, under certain circumstances, entitled to an increase in the conversion rate. In addition, if we undergo a fundamental change prior to the maturity date, holders may require us to repurchase for cash all or a portion of their Notes at a repurchase price equal to 100% of the principal amount of the repurchased Notes, plus accrued and unpaid interest. We may not redeem the Notes prior to the maturity date, and no sinking fund is provided for the Notes. In accounting for the issuance of the Notes, we separated the Notes into liability and equity components. The carrying amount of the liability component of approximately $423.4 million 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 of approximately $151.6 million , 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 liability component (the "debt discount") is amortized to interest expense using the effective interest method over the term of the Notes. The equity component of the Notes is included in additional paid-in capital in the condensed consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification. We incurred transaction costs related to the issuance of the Notes of approximately $11.5 million , consisting of an initial purchasers' discount of $10.8 million and other issuance costs of approximately $0.7 million . In accounting for the transaction costs, we allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds from the Notes. Transaction costs attributable to the liability component were approximately $8.5 million , recorded as debt issuance costs (presented as contra debt in the condensed consolidated balance sheets), and are being amortized to interest expense over the term of the Notes. The transaction costs attributable to the equity component were approximately $3.0 million and were net with the equity component within stockholders’ equity. The Notes consisted of the following: As of July 31, 2018 April 30, 2019 (in thousands) Principal amounts: Principal $ 575,000 $ 575,000 Unamortized debt discount (1) (137,719 ) (117,070 ) Unamortized debt issuance costs (1) (7,683 ) (6,531 ) Net carrying amount $ 429,598 $ 451,399 Carrying amount of equity component (2) $ 148,598 $ 148,598 (1) Included in the condensed consolidated balance sheets within convertible senior notes, net and amortized over the remaining life of the Notes using the effective interest rate method. The effective interest rate is 6.62% . (2) Included in the condensed consolidated balance sheets within additional paid-in capital, net of $3.0 million in equity issuance costs. As of April 30, 2019 , the remaining life of the Notes was approximately 44 months. The following table sets forth the total interest expense recognized related to the Notes: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands) Interest expense related to amortization of debt discount $ 6,550 $ 6,997 $ 7,250 $ 20,650 Interest expense related to amortization of debt issuance costs 366 390 404 1,152 Total interest expense $ 6,916 $ 7,387 $ 7,654 $ 21,802 Note Hedges and Warrants Concurrently with the offering of the Notes in January 2018, we entered into convertible note hedge transactions with certain bank counterparties, whereby we have the initial option to purchase a total of approximately 11.8 million shares of our Class A common stock at a conversion price of approximately $48.85 per share, subject to adjustment for certain specified events. The total cost of the convertible note hedge transactions was approximately $143.2 million . In addition, we sold warrants to certain bank counterparties, whereby the holders of the warrants have the initial option to purchase a total of approximately 11.8 million shares of our Class A common stock at a price of $73.46 per share, subject to adjustment for certain specified events. We received approximately $88.0 million in cash proceeds from the sale of these warrants. Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset any actual dilution from the conversion of the Notes and to effectively increase the overall conversion price from $48.85 to $73.46 per share. As these transactions meet certain accounting criteria, the convertible note hedges and warrants are recorded within stockholders’ equity and are not accounted for as derivatives. The net cost incurred in connection with the convertible note hedge and warrant transactions of approximately $55.2 million was recorded as a reduction to additional paid-in capital in the condensed consolidated balance sheets as of July 31, 2018 and April 30, 2019 . The fair value of the note hedges and warrants are not remeasured each reporting period. The amounts paid for the note hedges are tax deductible expenses, while the proceeds received from the warrants are not taxable. Impact to Earnings per Share The Notes will have no impact to diluted earnings per share ("EPS") until they meet the criteria for conversion, as discussed above, as we intend to settle the principal amount of the Notes in cash upon conversion. Under the treasury stock method, in periods when we report net income, we are required to include the effect of additional shares that may be issued under the Notes when the price of our Class A common stock exceeds the conversion price. Under this method, the cumulative dilutive effect of the Notes would be approximately 3.9 million shares if the average price of our Class A common stock was $73.46 . However, upon conversion, there will be no economic dilution from the Notes, as exercise of the note hedges eliminate any dilution that would have otherwise occurred. The note hedges are required to be excluded from the calculation of diluted earnings per share, as they would be antidilutive under the treasury stock method. The warrants will have a dilutive effect when the average share price exceeds the warrant strike price of $73.46 per share. As the price of our Class A common stock continues to increase above the warrant strike price, additional dilution would occur at a declining rate so that a $10 increase from the warrant strike price would yield a cumulative dilution of approximately 4.9 million diluted shares for EPS purposes. However, upon conversion, the note hedges would neutralize the dilution from the Notes so that there would only be dilution from the warrants, which would result in an actual dilution of approximately 1.4 million shares at a common stock price of $83.46 .

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Operating Leases We have commitments for future payments related to our office facility leases and other contractual obligations. We lease our office facilities under non-cancelable operating lease agreements expiring through 2026. Certain of these lease agreements have free or escalating rent payments. We recognize rent expense under such agreements on a straight-line basis over the lease term, with any free or escalating rent payments amortized as a reduction or addition of rent expense over the lease term. Future minimum payments due under operating leases as of April 30, 2019 are as follows: Fiscal Year Ending July 31: Amount (in thousands) 2019 (remaining three months) $ 9,244 2020 39,122 2021 35,738 2022 33,927 2023 31,386 Thereafter 26,244 Total $ 175,661 Purchase Commitments In the normal course of business, we make commitments with our contract manufacturers and OEMs to ensure them a minimum level of financial consideration for their investment in our joint solutions. These commitments are based on revenue targets or on-hand inventory and non-cancelable purchase orders for non-standard components. We record a charge related to these items when we determine that it is probable a loss will be incurred and we are able to estimate the amount of the loss. Our historical charges have not been material. As of April 30, 2019 , we had up to approximately $53.4 million of non-cancelable purchase commitments pertaining to our normal operations, and up to approximately $135.7 million in the form of guarantees to certain of our contract manufacturers and OEMs. Legal Proceedings Beginning on March 29, 2019, several purported securities class actions were filed in the United States District Court for the Northern District of California against us and two of our officers. The complaints generally allege that the defendants made false and misleading statements in violation of Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b-5. Although the definitions of the class vary slightly, the actions are generally brought on behalf of those who purchased our stock between March 2, 2018, and February 28, 2019, inclusive. The complaints seek monetary damages in an unspecified amount. These cases are in the very early stages and we are not able to determine what, if any, liabilities will attach to these complaints. We are not currently a party to any other legal proceedings that we believe to be material to our business or financial condition. From time to time, we may become party to various litigation matters and subject to claims that arise in the ordinary course of business.

EQUITY AWARD PLANS	EQUITY INCENTIVE PLANS Stock Plans We have three equity incentive plans, the 2010 Stock Plan ("2010 Plan"), 2011 Stock Plan ("2011 Plan") and 2016 Equity Incentive Plan ("2016 Plan"). Our stockholders approved the 2016 Plan in March 2016 and it became effective in connection with our initial public offering ("IPO"). As a result, at the time of the IPO, we ceased granting additional stock awards under the 2010 Plan and 2011 Plan and both plans were terminated. Any outstanding stock awards under the 2010 Plan and 2011 Plan will remain outstanding, subject to the terms of the applicable plan and award agreements, until such shares are issued under those stock awards, by exercise of stock options or settlement of restricted stock units ("RSUs"), or until those stock awards become vested or expired by their terms. Under the 2016 Plan, we may grant incentive stock options ("ISOs"), non-statutory stock options ("NSOs"), restricted stock, RSUs and stock appreciation rights to employees, directors and consultants. We initially reserved 22,400,000 shares of our Class A common stock for issuance under the 2016 Plan. The number of shares of Class A common stock available for issuance under the 2016 Plan will also include an annual increase on the first day of each fiscal year, beginning in fiscal 2018, equal to the lesser of: 18,000,000 shares, 5% of the outstanding shares of all classes of common stock as of the last day of our immediately preceding fiscal year, or such other amount as may be determined by the Board. Accordingly, on August 1, 2017 and 2018, the number of shares of Class A common stock available for issuance under the 2016 Plan increased by 7,731,826 and 8,642,904 shares, respectively, pursuant to these provisions. As of April 30, 2019 , we had reserved a total of 46,199,635 shares for the issuance of equity awards under the Stock Plans, of which 13,827,893 shares were still available for grant. Restricted Stock Units Performance RSUs — We grant RSUs that have both service and performance conditions to our executives and employees ("Performance RSUs"). Vesting of Performance RSUs is subject to continuous service and the satisfaction of certain performance targets. While we recognize cumulative stock-based compensation expense for the portion of the awards for which both the service condition has been satisfied and it is probable that the performance conditions will be met, the actual vesting and settlement of Performance RSUs are subject to the performance conditions actually being met. Market Stock Units — In October 2018, the Compensation Committee of our Board of Directors approved the grant of 100,000 RSUs subject to certain market conditions ("MSUs") to our Chief Executive Officer ("CEO"), with a weighted average grant date fair value per unit of $25.16 . The MSUs will vest based upon the achievement of an average stock price of $80 over a performance period of approximately 4.5 years (the “Performance Period”), subject to his continuous service on each vesting date. The average stock price is calculated based on the average closing price of one share of our Class A common stock, as reported on the NASDAQ Stock Market during the 180-day period ending on the last trading day prior to each measurement date (as applicable, the “Average Stock Price”). The Average Stock Price is measured once per quarter during the Performance Period, and: • If the Average Stock Price on any given quarterly measurement date does not equal or exceed $80 , then none of the MSUs will vest that quarter, and any unvested MSUs will carry over to the next quarter (the “Carryover MSUs”); • If the Average Stock Price on any given quarterly measurement date equals or exceeds $80 , then 1/18th of the MSUs plus the applicable Carryover MSUs, if any, would vest; and/or • If the Average Stock Price never equals or exceeds $80 during the Performance Period, the MSUs would terminate at the end of the Performance Period. We used a Monte Carlo simulation to calculate the fair value of the award on the grant date. A Monte Carlo simulation requires the use of various assumptions, including the stock price volatility and risk free interest rate as of the valuation date corresponding to the length of time remaining in the performance period and expected dividend yield. We recognize stock-based compensation expense related to these MSUs using the graded vesting attribution method over the Performance Period. As of April 30, 2019 , 100,000 MSUs remained outstanding. Below is a summary of RSU activity, including MSUs, under the Stock Plans: Number of Grant Date Fair Value per Share Outstanding at July 31, 2018 23,597,499 $ 31.20 Granted 8,445,399 $ 47.63 Vested (6,382,260 ) $ 28.07 Canceled/forfeited (2,426,308 ) $ 35.03 Outstanding at April 30, 2019 23,234,330 $ 37.63 Stock Options We did not grant any stock options during the nine months ended April 30, 2019 . A total of 2,194,303 stock options were exercised during the nine months ended April 30, 2019 , with an average exercise price per share of $4.64 . As of April 30, 2019 , 9,103,232 stock options, with a weighted average exercise price of $5.22 per share, a weighted average remaining contractual life of 4.9 years and an aggregate intrinsic value of $345.7 million , remained outstanding. Employee Stock Purchase Plan In December 2015, the Board adopted the 2016 Employee Stock Purchase Plan ("2016 ESPP"), which was subsequently amended in January 2016 and September 2016 and approved by our stockholders in March 2016. The 2016 ESPP became effective in connection with our IPO. A total of 3,800,000 shares of Class A common stock were initially reserved for issuance under the 2016 ESPP. The number of shares of Class A common stock available for sale under the 2016 ESPP also includes an annual increase on the first day of each fiscal year, beginning in fiscal 2018, equal to the lesser of: 3,800,000 shares, 1% of the outstanding shares of all classes of common stock as of the last day of our immediately preceding fiscal year, or such other amount as may be determined by the Board. Accordingly, on August 1, 2017 and 2018, the number of shares of Class A common stock available for issuance under 2016 ESPP increased by 1,546,365 and 1,728,580 shares, respectively, pursuant to these provisions. The 2016 ESPP allows eligible employees to purchase shares of our Class A common stock at a discount through payroll deductions of up to 15% of eligible compensation, subject to caps of $25,000 in any calendar year and 1,000 shares on any purchase date. The 2016 ESPP provides for 12 -month offering periods, generally beginning in March and September of each year, and each offering period consists of two six-month purchase periods. On each purchase date, participating employees will purchase Class A common stock at a price per share equal to 85% of the lesser of the fair market value of our Class A common stock on (i) the first trading day of the applicable offering period or (ii) the last trading day of each purchase period in the applicable offering period. If the stock price of our Class A common stock on any purchase date in an offering period is lower than the stock price on the enrollment date of that offering period, the offering period will immediately reset after the purchase of shares on such purchase date and automatically roll into a new offering period. During the nine months ended April 30, 2019 , 2,008,082 shares of common stock were purchased under the 2016 ESPP for an aggregate amount of $57.2 million . As of April 30, 2019 , 1,402,959 shares were available for future issuance under the 2016 ESPP. We use the Black-Scholes option pricing model to determine the fair value of shares purchased under the 2016 ESPP with the following weighted average assumptions on the date of grant: Nine Months Ended 2018 2019 Expected term (in years) 0.75 0.84 Risk-free interest rate 1.4 % 2.5 % Volatility 49.8 % 69.0 % Dividend yield — % — % Stock-Based Compensation Total stock-based compensation expense recognized in the condensed consolidated statements of operations is as follows: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands) Cost of revenue: Product $ 634 $ 953 $ 1,888 $ 2,523 Support, entitlements and other services 1,951 4,542 6,156 11,072 Sales and marketing 18,051 35,257 47,759 81,325 Research and development 16,474 42,265 49,039 107,953 General and administrative 7,836 11,815 17,630 30,449 Total stock-based compensation expense $ 44,946 $ 94,832 $ 122,472 $ 233,322 As of April 30, 2019 , unrecognized stock-based compensation expense related to outstanding stock awards was approximately $791.3 million and is expected to be recognized over a weighted average period of approximately 2.5 years

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The income tax benefit $0.8 million and provision of $3.3 million for the three and nine months ended April 30, 2018 , respectively, primarily consisted of foreign taxes on our international operations, partially offset by a $3.9 million valuation allowance release in connection with acquisitions. The income tax provisions of $2.4 million and $1.0 million for the three and nine months ended April 30, 2019 , respectively, primarily consisted of foreign taxes on our international operations and U.S. state income taxes. The income tax provision for the nine months ended April 30, 2019 was partially offset by a $5.8 million U.S. valuation allowance release in connection with an acquisition and a tax benefit related to the change in tax law. The net deferred tax liabilities recorded in connection with these acquisitions provided an additional source of taxable income to support the realizability of the pre-existing deferred tax assets and as a result, we released a portion of our U.S. valuation allowance. We continue to maintain a valuation allowance for our U.S. Federal and state deferred tax assets. In December 2017, the U.S. Congress passed, and the President signed, the Tax Cuts and Jobs Act, which includes a broad range of tax reform proposals affecting businesses, including a federal corporate rate reduction from 35% to 21%, effective January 1, 2018, limitations on the deductibility of interest expense and executive compensation, the creation of new minimum taxes, such as the base erosion anti-abuse tax ("BEAT") and Global Intangible Low Taxed Income ("GILTI") tax and a new minimum tax on certain foreign earnings. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which allowed us to record provisional amounts during a measurement period not to extend beyond one year from the enactment date. The SAB 118 measurement period ended in December 2018. As such, during the second quarter of fiscal 2019, we completed our analysis based on the current legislative updates related to the TCJA and noted no additional guidance or information that affects the provisional amounts previously recorded. Although our analysis of the tax effects of the TCJA is complete, there may be additional tax effects that could impact our future consolidated financial statements upon the finalization of any laws, regulations or additional TCJA guidance. In January 2018, the FASB released guidance on the accounting for the GILTI provisions of the TCJA. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. During the second quarter of fiscal 2019, we elected to treat any potential GILTI inclusions as a period cost.

Earnings Per Share [Abstract]
NET LOSS PER SHARE	NET LOSS PER SHARE Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by giving effect to potentially dilutive common stock equivalents outstanding during the period, as their effect would be dilutive. Potentially dilutive common shares include participating securities and shares issuable upon the exercise of stock options, the exercise of common stock warrants, the exercise of convertible preferred stock warrants, the vesting of RSUs and each purchase under the 2016 ESPP, under the treasury stock method. In loss periods, basic net loss per share and diluted net loss per share are the same, as the effect of potential common shares is antidilutive and therefore excluded. The rights, including the liquidation and dividend rights, of the holders of our Class A and Class B common stock are identical, except with respect to voting. As the liquidation and dividend rights are identical, our undistributed earnings or losses are allocated on a proportionate basis among the holders of both Class A and Class B common stock. As a result, the net income (loss) per share attributed to common stockholders will, therefore, be the same for both Class A and Class B common stock on an individual or combined basis. The computation of basic and diluted net loss per share attributable to Class A and Class B common stockholders is as follows: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands, except share and per share data) Numerator: Net loss $ (85,674 ) $ (209,813 ) $ (209,792 ) $ (426,841 ) Denominator: Weighted average shares—basic and diluted 166,845,544 182,962,921 161,709,365 179,235,498 Net loss per share attributable to common stockholders—basic and diluted $ (0.51 ) $ (1.15 ) $ (1.30 ) $ (2.38 ) The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive are as follows: Three and Nine Months Ended 2018 2019 Outstanding stock options and RSUs 35,206,318 32,337,562 Employee stock purchase plan 1,341,470 1,657,333 Contingently issuable shares pursuant to business combinations 276,625 748,172 Common stock subject to repurchase 73,360 6,251 Common stock warrants 34,180 34,180 Total 36,931,953 34,783,498

Accounting Policies [Abstract]
Principles of Consolidation and Significant Accounting Policies	Principles of Consolidation and Significant Accounting Policies The accompanying condensed 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") and are consistent in all material respects with those included in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018 , filed with the Securities and Exchange Commission ("SEC") on September 24, 2018. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements are unaudited, but include all adjustments of a normal recurring nature necessary for a fair presentation of our quarterly results. 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. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes in our Annual Report on Form 10-K for the fiscal year ended July 31, 2018 .
Use of Estimates	Use of Estimates The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed 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 stock-based awards; 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 of Risk Concentration of revenue and accounts receivable —We sell our products primarily through our Partners and occasionally directly to end customers. For the three and nine months ended April 30, 2018 and 2019 , no end customer accounted for more than 10% of total revenue or accounts receivable.
Recently Issued and Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires us to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted this ASU effective August 1, 2018 using a modified retrospective approach. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which 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. The new standard was effective for fiscal years beginning after December 15, 2017, with early adoption permitted, including interim reporting periods within those fiscal years. We adopted the new standard effective August 1, 2018, using the retrospective transition approach. The reclassified restricted cash balances from operating activities to changes in cash, cash equivalents and restricted cash on the condensed consolidated statements of cash flows were not material for any period presented. 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. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other (Topic 350): Internal-Use Software, which standard aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We early adopted the standard effective August 1, 2018, using the prospective approach, and our adoption did not have a significant impact on our condensed consolidated financial statements. In August 2018, the SEC issued Securities Act Release No. 33-10532, which amends certain disclosure requirements, including extending to interim periods the annual requirement to disclose changes in stockholders’ equity. Under the new requirements, registrants must now analyze changes in stockholders’ equity, in the form of a reconciliation, for the current and comparative year-to-date interim periods, with subtotals for each interim period. The final rule was effective in November 2018. We adopted this new guidance during the first quarter of fiscal 2019 and have included a reconciliation of the changes in stockholders' equity in this Quarterly Report on Form 10-Q. Recently Issued and Not Yet Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, which requires the recognition of right-of-use lease assets and lease liabilities for all leases, except for short-term leases, on the condensed consolidated balance sheets of lessees. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years. We will adopt the standard effective August 1, 2019 and we intend to elect certain practical expedients, including the transition option that will allow us to not have to restate the comparative periods in our condensed consolidated financial statements in the year of adoption. We currently anticipate that the adoption of this standard will have a material impact on our condensed consolidated balance sheets, given that we had operating lease commitments in excess of $175 million as of April 30, 2019 , on an undiscounted basis. We expect that most of our operating lease commitments will be subject to the new standard and will be recognized as lease liabilities and right-of-use assets upon adoption, which will increase our total assets and total liabilities reported. However, we do not anticipate that the adoption of this standard will have a material impact on our condensed consolidated statements of operations, as the expense recognition under the new standard will be similar to current practice. We do not expect the adoption of this standard to have a material impact on our condensed consolidated statements of cash flows. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which provides companies with an option to reclassify stranded tax effects resulting from the enactment of the Tax Cuts and Jobs Act ("TCJA") from accumulated other comprehensive income to retained earnings. The new standard is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including interim reporting periods within those fiscal years, and will be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the tax rate as a result of TCJA is recognized. We have not made a determination as to which alternative method we will use upon adoption of the standard, but we do not expect the adoption of this ASU to have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of the FASB's disclosure framework project. The new standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including interim reporting periods within those fiscal years. We do not expect the adoption of this ASU to have a significant impact on our quarterly or annual disclosures.
Revenue Recognition	We generate revenue primarily from the sale of our enterprise cloud platform, which can be delivered pre-installed on an appliance that is configured to order or delivered separately to be utilized on a variety of certified hardware platforms. Software delivered on configured to order appliances is not portable to other appliances and has a term equal to the life of the associated appliance, while subscription term-based licenses typically have a term of one to five years
