Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	1. Description of Business and Significant Accounting Policies NetApp, Inc. (we, us, or the Company) provides global organizations the ability to manage and share their data across on-premises, private and public clouds. Together with our partners, we provide a full range of enterprise-class software, systems and services solutions that customers use to modernize their infrastructures, build next generation data centers and harness the power of hybrid clouds. Basis of Presentation and Preparation Our fiscal year is reported on a 52- or 53-week year ending on the last Friday in April. An additional week is included in the first fiscal quarter approximately every six years to realign fiscal months with calendar months. Fiscal years 2018 and 2017, ending on April 27, 2018, and April 28, 2017, respectively, are each 52-week years, with 13 weeks in each of their quarters. The accompanying unaudited condensed consolidated financial statements have been prepared by the Company, and reflect all adjustments, consisting only of normal recurring adjustments, that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Accordingly, these statements do not include all information and footnotes required by GAAP for annual consolidated financial statements, and should be read in conjunction with our audited consolidated financial statements as of and for the fiscal year ended April 28, 2017 contained in our Annual Report on Form 10-K. The results of operations for the three and nine months ended January 26, 2018 are not necessarily indicative of the operating results to be expected for the full fiscal year or future operating periods. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, reserves and allowances; inventory valuation and purchase order accruals; valuation of goodwill and intangibles; restructuring reserves; product warranties; employee compensation and benefit accruals; stock-based compensation; loss contingencies; valuation of investment securities; income taxes and fair value measurements. Actual results could differ materially from those estimates. There have been no significant changes in our significant accounting policies as of and for the nine months ended January 26, 2018, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 28, 2017.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Standards Not Yet Effective	2. Recent Accounting Standards Not Yet Effective Revenue from Contracts with Customers In May 2014, the FASB issued an accounting standards update related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method. We will adopt this new standard, as amended, on its effective date in the first quarter of fiscal 2019. Preliminarily, we plan to adopt the standard using the full retrospective method to restate each prior reporting period presented. Our ability to adopt this standard using the full retrospective method is dependent upon system readiness, for both revenue and commissions, and the completion of the analysis of information necessary to restate prior period financial statements and disclosures. We are continuing to assess the impact of this standard on our financial position, results of operations and related disclosures and have not yet determined whether the effect will be material. We do not expect that the adoption of this standard will have a material impact on our operating cash flows. Additionally, as we continue to assess the new standard along with industry trends and additional interpretive guidance, we may adjust our implementation plan accordingly. We believe that the new standard will impact the following policies and disclosures: • in arrangements containing software, revenue deferred for the undelivered elements will be based on a relative fair value allocation, generally resulting in more software arrangement revenue being recognized earlier; • removal of the current limitation on contingent revenue for multiple element arrangements, such as that related to the delivery of additional items or meeting other specified performance conditions, may result in revenue being recognized earlier; • estimation of variable consideration for arrangements with contract terms such as rights of return, potential penalties and acceptance clauses; • required disclosures, including information about the transaction price allocated to remaining performance obligations and expected timing of revenue recognition; and • accounting for deferred commissions, including costs that qualify for deferral and the amortization period. We do not expect that the new standard will result in substantive changes in our deliverables or the amounts of revenue allocated between multiple deliverables, with the exception of the items discussed above. Leases In February 2016, the FASB issued an accounting standards update on financial reporting for leasing arrangements, including requiring lessees to recognize an operating lease with a term greater than one year on their balance sheets as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. This new standard will be effective for us in our first quarter of fiscal 2020, although early adoption is permitted. Upon adoption, lessees must apply a modified retrospective transition approach for leases existing at, or Credit Losses on Financial Instruments In June 2016, the FASB issued an accounting standards update on the measurement of credit losses on financial instruments. The standard introduces a new model for measuring and recognizing credit losses on financial instruments, requiring financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. Income Taxes on Intra-Entity Transfers of Assets In October 2016, the FASB issued an accounting standards update that requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This amends current GAAP which prohibits recognition of current and deferred income taxes for all types of intra-entity asset transfers until the asset has been sold to an outside party. This new standard will be effective for us in our first quarter of fiscal 2019, although early adoption is permitted. Upon adoption, companies must apply a modified retrospective transition approach through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. We are currently evaluating the impact of this new standard on our consolidated financial statements. Derecognition of Non-Financial Assets In February 2017, the FASB issued an accounting standards update that amends guidance on how entities account for the derecognition of a nonfinancial asset or an in substance nonfinancial asset that is not a business. The guidance allows for the use of either the full or modified retrospective transition method. This new standard will be effective for us in our first quarter of fiscal 2019, although early adoption is permitted. We are currently evaluating the impact of this new standard on our consolidated financial statements. Although there are several other new accounting pronouncements issued or proposed by the FASB that we have adopted or will adopt, as applicable, we do not believe any of these accounting pronouncements has had or will have a material impact on our consolidated financial position, operating results or disclosures.

Investments Debt And Equity Securities [Abstract]
Financial Instruments and Fair Value Measurements	8. Financial Instruments and Fair Value Measurements The accounting guidance for fair value measurements provides a framework for measuring fair value on either a recurring or nonrecurring basis, whereby the inputs used in valuation techniques are assigned a hierarchical level. The following are the three levels of inputs to measure fair value: Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Inputs that reflect quoted prices for identical assets or liabilities in less active markets; quoted prices for similar assets or liabilities in active markets; benchmark yields, reported trades, broker/dealer quotes, inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3: Unobservable inputs that reflect our own assumptions incorporated in valuation techniques used to measure fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. We consider an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and consider an inactive market to be one in which there are infrequent or few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, our own or the counterparty’s non-performance risk is considered in measuring the fair values of liabilities and assets, respectively. Investments The following is a summary of our investments (in millions): January 26, 2018 April 28, 2017 Cost or Estimated Cost or Estimated Amortized Gross Unrealized Fair Amortized Gross Unrealized Fair Cost Gains Losses Value Cost Gains Losses Value Corporate bonds $ 1,888 $ 3 $ (14 ) $ 1,877 $ 1,535 $ 3 $ (2 ) $ 1,536 U.S. Treasury and government debt securities 520 — (4 ) 516 629 1 (2 ) 628 Foreign government debt securities 12 — — 12 21 — — 21 Commercial paper 544 — — 544 362 — — 362 Certificates of deposit 107 — — 107 99 — — 99 Mutual funds 33 — — 33 31 — — 31 Total debt and equity securities $ 3,104 $ 3 $ (18 ) $ 3,089 $ 2,677 $ 4 $ (4 ) $ 2,677 As of January 26, 2018 and April 28, 2017, gross unrealized losses related to individual securities were not significant.

These pricing providers utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities. We review Level 2 inputs and fair value for reasonableness and the values may be further validated by comparison to multiple independent pricing sources. In addition, we review third-party pricing provider models, key inputs and assumptions and understand the pricing processes at our third-party providers in determining the overall reasonableness of the fair value of our Level 2 debt instruments. As of January 26, 2018 and April 28, 2017, we have not made any adjustments to the prices obtained from our third-party pricing providers. Fair Value of Debt As of January 26, 2018 and April 28, 2017, the fair value of our long-term debt was approximately $1,551 million and $1,520 million, respectively. The fair value of our long-term debt was based on observable market prices in a less active market. The fair value of our commercial paper notes approximated their carrying value. All of our debt obligations are categorized as Level 2 instruments.

On November 3, 2017, we extinguished our 2.00% Senior Notes due December 2017 for an aggregate redemption price of $751 million, plus accrued and unpaid interest. Interest on our Senior Notes issued in September 2017 is payable semi-annually in March and September. Our 3.375% Senior Notes and 3.25% Senior Notes, with principal amounts of $500 million and $250 million, respectively, were issued in June 2014 and December 2012, respectively. Interest on these Senior Notes is paid semi-annually in June and December. Our Senior Notes, which are unsecured, unsubordinated obligations, rank equally in right of payment with any existing and future senior unsecured indebtedness. We may redeem the Senior Notes in whole or in part, at any time at our option at specified redemption prices. In addition, upon the occurrence of certain change of control triggering events, we may be required to repurchase the Senior Notes under specified terms. The Senior Notes also include covenants that limit our ability to incur debt secured by liens on assets or on shares of stock or indebtedness of our subsidiaries; to engage in certain sale and lease-back transactions; and to consolidate, merge or sell all or substantially all of our assets. As of January 26, 2018, we were in compliance with all covenants associated with the Senior Notes. As of January 26, 2018, our aggregate future principal debt maturities are as follows (in millions): Fiscal Year Amount 2020 $ 400 2022 500 Thereafter 650 Total $ 1,550 Commercial Paper Program and Credit Facility We have a commercial paper program (the Program), under which we may issue unsecured commercial paper notes. Amounts available under the Program, as amended on July 17, 2017, may be borrowed, repaid and re-borrowed, with the aggregate face or principal amount of the notes outstanding under the Program at any time not to exceed $1.0 billion. The proceeds from the issuance of the notes are used for general corporate purposes. As of January 26, 2018, we had commercial paper notes outstanding with an aggregate principal amount of $632 million, a weighted-average interest rate of 1.81% and maturities ranging from 17 days to 46 days. In connection with the Program, we have a senior unsecured credit agreement with a syndicated group of lenders that expires on December 10, 2021. The credit agreement, as amended on July 17, 2017, provides a $1.0 billion revolving unsecured credit facility, with a $50 million letter of credit sub-facility, that serves as a back-up for the Program. Proceeds from the facility may also be used for general corporate purposes to the extent that the credit facility exceeds the outstanding debt issued under the Program . The credit agreement includes options that allow us to request an increase in the facility of up to an additional $300 million and to extend its maturity date for two additional one-year periods, both subject to certain conditions. As of January 26, 2018 we were in compliance with all associated covenants in this agreement. No amounts were drawn against this facility during any of the periods presented. Sale-leaseback Transactions In fiscal 2016, we entered into a sale-leaseback arrangement of certain of our land and buildings, under which we leased back certain of our properties rent free over lease terms ending at various dates through December 31, 2017. These properties did not qualify for sale-leaseback accounting and as a result they were accounted for as financing transactions. In December 2017, we terminated the leases and recorded a non-cash sale of properties with a net book value of $54 million, the extinguishment of $130 million in financing obligations, and a gain of $76 million. As of January 26, 2018, there are no balances remaining on our condensed consolidated balance sheets associated with this sale-leaseback arrangement.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	11. Derivatives and Hedging Activities We use derivative instruments to manage exposures to foreign currency risk. Our primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. The maximum length of time over which forecasted foreign currency denominated revenues are hedged is six months. The program is not designated for trading or speculative purposes. Our derivatives expose us to credit risk to the extent that the counterparties may be unable to meet the terms of our agreements with them. We seek to mitigate such risk by limiting our counterparties to major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored on an ongoing basis. We also have in place master netting arrangements to mitigate the credit risk of our counterparties and to potentially reduce our losses due to counterparty nonperformance. We present our derivative instruments as net amounts in our condensed consolidated balance sheets. The gross and net fair value amounts of such instruments were not material as of January 26, 2018 or April 28, 2017. We did not recognize any gains or losses in earnings due to hedge ineffectiveness for any period presented. All contracts have a maturity of less than six months. The notional amount of our outstanding U.S. dollar equivalent foreign currency exchange forward contracts consisted of the following (in millions): January 26, 2018 April 28, 2017 Balance Sheet Contracts Forward contracts sold $ 125 $ 165 Forward contracts purchased $ 531 $ 257 As of January 26, 2018 and April 28, 2017, there were no instruments designated as cash flow hedges outstanding. The effect of cash flow hedges recognized in net revenues is presented in the condensed consolidated statements of comprehensive income (loss) and in Note 10 – Stockholders’ Equity.

Restructuring Charges	12. Restructuring Charges Management has previously approved several restructuring actions to streamline our business, eliminate costs and redirect resources to our highest return activities, including the March 2016 Plan and the November 2016 Plan, under which we reduced our global workforce by approximately 11%, and 6%, respectively. We completed all workforce related activities under these plans as of the end of fiscal 2017. Charges related to our restructuring plans consisted primarily of employee severance-related costs. The remaining balance as of January 26, 2018 principally relates to lease obligations that will be paid over their remaining terms.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes Our effective tax rates for the periods presented were as follows: Nine Months Ended January 26, 2018 January 27, 2017 Effective tax rates 122.6 % 23.5 % Our effective tax rates reflect the impact of a significant amount of our earnings, primarily income from our European operations which are headquartered in the Netherlands, being taxed in foreign jurisdictions at rates below the United States (U.S.) statutory tax rate. The differences in effective tax rates for the nine months ended January 26, 2018 and January 27, 2017 were primarily related to the impacts of recent U.S. tax reform and the sale of certain buildings and land in Sunnyvale, California. On December 22, 2017, the 2017 Tax Reform Reconciliation Act, originally referred to as the Tax Cuts and Jobs Act (“TCJA”) was enacted into law and is effective for the third quarter of our fiscal 2018. The TCJA made significant changes to the U.S. corporate income tax system including a reduction of the U.S. federal corporate income tax rate, the imposition of a one-time transition tax on deferred foreign earnings, and a shift to a modified territorial tax regime. ASC 740, Income Taxes, requires that the impact on income taxes due to a change in legislation be recognized in the period of enactment. Given the timing and pace of regulatory guidance, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin 118, which allows for the recording of provisional amounts related to U.S. tax reform and subsequent related adjustments during a measurement period. As of January 26, 2018, we have not fully completed the accounting for the tax impacts of the TCJA and have recorded provisional tax charges based on reasonable estimates for the transition tax on our total post-1986 foreign earnings and profits (“E&P”), and for the remeasurement of deferred tax assets and liabilities based on the new corporate tax rate. The TCJA also includes provisions for a global minimum tax on intangible low-taxed income (“GMT”) of foreign subsidiaries, a base erosion anti-abuse tax on certain intercompany payments, and beneficial tax treatment for foreign derived intangible income. These provisions will be effective for us beginning in our fiscal 2019. We will continue to refine provisional balances and make adjustments during the measurement period based on the issuance of further regulatory guidance, changes in interpretations, and the collection and analysis of additional information; these adjustments could be material to our financial statements. The provisional amounts recorded during the current quarter are explained below. The TJCA decreased the U.S. federal corporate tax rate from 35% to 21% as of January 1, 2018. For fiscal 2018, this decrease results in a blended statutory tax rate of 30.5%. As a result of the tax rate change, we remeasured our deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future periods and recorded a $117 million discrete tax expense for the quarter. The final remeasurement impact could vary from the provisional amount if actual future activities impacting deferred tax balances differ from our estimates. The TCJA imposes a mandatory, one-time transition tax on accumulated foreign E&P not previously subject to U.S. income tax at a rate of 15.5% on earnings to the extent of foreign cash and other liquid assets, and 8% on the remaining earnings. During the quarter, we recorded a $739 million discrete tax expense for the estimated U.S. federal and state income tax impacts of the transition tax. Our estimates may change with further guidance from U.S. federal and state tax authorities or other regulatory bodies, our fourth quarter activities, and additional analyses that we expect to complete during the measurement period, with respect to various components of the computations. We intend to make the election to pay the one-time transition tax over a period of eight years. Under the TCJA, the GMT provision taxes foreign income in excess of a deemed return on tangible assets of foreign corporations. Under U.S. GAAP, companies are allowed to make an accounting policy election to either (i) account for GMT as a component of tax expense in the period in which a company is subject to the rules (the “period cost method”), or (ii) account for GMT in a company’s measurement of deferred taxes (the “deferred method”). Because of the complexity of the new tax rules, we are continuing to evaluate this provision and the application of ASC 740 and have not yet made an accounting policy election. As a part of the provisional estimates recorded during the quarter, we considered the impacts of the TCJA and reviewed our projected global cash requirements, and have determined that certain historical and future foreign earnings will no longer be indefinitely reinvested. During the quarter ended January 26, 2018, we also recorded a $72 million discrete tax expense related to the sale of certain buildings and land in Sunnyvale, California. The expense partially relates to gains triggered by the termination of a fiscal 2016 sale-leaseback arrangement. The remainder of the expense relates to the sale of buildings and land in the current quarter. As of January 26, 2018, we had $338 million of gross unrecognized tax benefits, and $303 million has been recorded in other long-term liabilities inclusive of penalties, interest and indirect benefits. Unrecognized tax benefits of $284 million, including penalties, interest and indirect benefits, would affect our provision for income taxes if recognized. As result of the U.S. tax reform, we recorded $113 million of gross unrecognized tax benefits. We are currently undergoing federal income tax audits in the U.S. and several foreign tax jurisdictions. Transfer pricing calculations are key issues under audits in various jurisdictions, and are often subject to dispute and appeals. The IRS has concluded the examination of our tax returns for our fiscal years through 2010. The IRS commenced the examination of our federal income tax returns for our fiscal years 2012 and 2013 in August 2016. On September 17, 2010, the Danish Tax Authorities issued a decision concluding that distributions declared in 2005 and 2006 from our Danish subsidiary were subject to Danish at-source dividend withholding tax. We do not believe that our Danish subsidiary is liable for withholding tax and filed an appeal with the Danish Tax Tribunal to that effect. On December 19, 2011, the Danish Tax Tribunal issued a ruling that our Danish subsidiary was not liable for Danish withholding tax. The Danish tax examination agency appealed to the Danish High Court in March 2012. In February 2016, the Danish High Court referred the case to the Court of Justice of the European Union where it was heard before the court in October 2017. We expect the court to issue their opinion and judgment by the end of fiscal 2018. We continue to monitor the progress of ongoing discussions with tax authorities and the impact, if any, of the expected expiration of the statute of limitations in various taxing jurisdictions.

Segment, Geographic, and Significant Customer Information	15. Segment, Geographic, and Significant Customer Information We operate in one industry segment: the design, manufacturing, marketing, and technical support of high-performance storage and data management solutions. We conduct business globally, and our sales and support activities are managed on a geographic basis. Our management reviews financial information presented on a consolidated basis, accompanied by disaggregated information it receives from our internal management system about revenues by geographic region, based on the location from which the customer relationship is managed, for purposes of allocating resources and evaluating financial performance. We do not allocate costs of revenues, research and development, sales and marketing, or general and administrative expenses to our geographic regions in this internal management reporting because management does not review operations or operating results, or make planning decisions, below the consolidated entity level. Summarized revenues by geographic region based on information from our internal management system and utilized by our Chief Executive Officer, who is considered our Chief Operating Decision Maker, is as follows (in millions): Three Months Ended Nine Months Ended January 26, 2018 January 27, 2017 January 26, 2018 January 27, 2017 United States, Canada and Latin America (Americas) $ 823 $ 767 $ 2,345 $ 2,271 Europe, Middle East and Africa (EMEA) 487 460 1,319 1,243 Asia Pacific (APAC) 213 177 606 524 Net revenues $ 1,523 $ 1,404 $ 4,270 $ 4,038 Americas revenues consist of sales to Americas commercial and U.S. public sector markets.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. Commitments and Contingencies Operating Leases We lease various equipment, vehicles and office space in the U.S. and internationally. Future annual minimum lease payments under non-cancelable operating leases with an initial term in excess of one year totaled $198 million as of January 26, 2018. Purchase Orders and Other Commitments In the ordinary course of business, we make commitments to third-party contract manufacturers to manage manufacturer lead times and meet product forecasts, and to other parties to purchase various key components used in the manufacturing of our products. A significant portion of our reported purchase commitments arising from these agreements consists of firm, non-cancelable, and unconditional commitments. As of January 26, 2018, we had $387 million in non-cancelable purchase commitments for inventory. We record a liability for firm, non-cancelable and unconditional purchase commitments for quantities in excess of our future demand forecasts consistent with the valuation of our excess and obsolete inventory. As of January 26, 2018 and April 28, 2017, such liability amounted to $11 million and $10 million, respectively, and is included in accrued expenses in our condensed consolidated balance sheets. To the extent that such forecasts are not achieved, our commitments and associated accruals may change. In addition to inventory commitments with contract manufacturers and component suppliers, we have open purchase orders and contractual obligations associated with our ordinary course of business for which we have not yet received goods or services. As of January 26, 2018, we had $15 million in construction related obligations and $222 million in other purchase obligations. Financing Guarantees While most of our arrangements for sales include short-term payment terms, from time to time we provide long-term financing to creditworthy customers. We have generally sold receivables financed through these arrangements on a non-recourse basis to third party financing institutions within 10 days of the contracts’ dates of execution, and we classify the proceeds from these sales as cash flows from operating activities in our condensed consolidated statements of cash flows. We account for the sales of these receivables as “true sales” as defined in the accounting standards on transfers of financial assets, as we are considered to have surrendered control of these financing receivables. Provided all other revenue recognition criteria have been met, we recognize product revenues for these arrangements, net of any payment discounts from financing transactions, upon product acceptance. We sold $62 million and $142 million of receivables during the nine months ended January 26, 2018 and January 27, 2017, respectively. In addition, we enter into arrangements with leasing companies for the sale of our hardware systems products. These leasing companies, in turn, lease our products to end-users. The leasing companies generally have no recourse to us in the event of default by the end-user and we recognize revenue upon delivery to the end-user customer, if all other revenue recognition criteria have been met. Some of the leasing arrangements described above have been financed on a recourse basis through third-party financing institutions. Under the terms of recourse leases, which are generally three years or less, we remain liable for the aggregate unpaid remaining lease payments to the third-party leasing companies in the event of end-user customer default. These arrangements are generally collateralized by a security interest in the underlying assets. Where we provide a guarantee for recourse leases, we defer revenues subject to the industry-specific software revenue recognition guidance and recognize revenues for non-software deliverables in accordance with our multiple deliverable revenue arrangement policy. In connection with certain recourse financing arrangements, we receive advance payments associated with undelivered elements that are subject to customer refund rights. We defer revenue associated with these advance payments until the related refund rights expire and we perform the services. As of January 26, 2018 and April 28, 2017, the aggregate amount by which such contingencies exceeded the associated liabilities was not significant. To date, we have not experienced significant losses under our lease financing programs or other financing arrangements . We have entered into service contracts with certain of our end-user customers that are supported by third-party financing arrangements. If a service contract is terminated as a result of our non-performance under the contract or our failure to comply with the terms of the financing arrangement, we could, under certain circumstances, be required to acquire certain assets related to the service contract or to pay the aggregate unpaid financing payments under such arrangements. As of January 26, 2018, we have not been required to make any payments under these arrangements, and we believe the likelihood of having to acquire a material amount of assets or make payments under these arrangements is remote. The portion of the financial arrangement that represents unearned services revenue is included in deferred revenue and financed unearned services revenue in our condensed consolidated balance sheets . Legal Contingencies When a loss is considered probable and reasonably estimable, we record a liability in the amount of our best estimate for the ultimate loss. However, the likelihood of a loss with respect to a particular contingency is often difficult to predict, and determining a meaningful estimate of the loss or a range of loss may not be practicable based on the information available and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. We are subject to various legal proceedings and claims that arise in the normal course of business. We may, from time to time, receive claims that we are infringing third parties’ intellectual property rights, including claims for alleged patent infringement brought by non-practicing entities. We are currently involved in patent litigations brought by non-practicing entities and other third parties. We believe we have strong arguments that our products do not infringe and/or the asserted patents are invalid, and we intend to vigorously defend against the plaintiffs’ claims. However, there is no guarantee that we will prevail at trial and if a jury were to find that our products infringe, we could be required to pay significant monetary damages, and may cause product shipment delays, require us to redesign our products, or require us to enter into royalty or licensing agreements. Although management at present believes that the ultimate outcome of these proceedings, individually and in the aggregate, will not materially harm our financial position, results of operations, cash flows, or overall trends, legal proceedings are subject to inherent uncertainties, and unfavorable rulings or other events could occur. Unfavorable resolutions could include significant monetary damages. In addition, in matters for which injunctive relief or other conduct remedies are sought, unfavorable resolutions could include an injunction or other order prohibiting us from selling one or more products at all or in particular ways or requiring other remedies. An unfavorable outcome may result in a material adverse impact on our business, results of operations, financial position, and overall trends. No material accrual has been recorded as of January 26, 2018 related to such matters.

Accounting Policies [Abstract]
Basis of Presentation and Preparation	Basis of Presentation and Preparation Our fiscal year is reported on a 52- or 53-week year ending on the last Friday in April. An additional week is included in the first fiscal quarter approximately every six years to realign fiscal months with calendar months. Fiscal years 2018 and 2017, ending on April 27, 2018, and April 28, 2017, respectively, are each 52-week years, with 13 weeks in each of their quarters. The accompanying unaudited condensed consolidated financial statements have been prepared by the Company, and reflect all adjustments, consisting only of normal recurring adjustments, that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Accordingly, these statements do not include all information and footnotes required by GAAP for annual consolidated financial statements, and should be read in conjunction with our audited consolidated financial statements as of and for the fiscal year ended April 28, 2017 contained in our Annual Report on Form 10-K. The results of operations for the three and nine months ended January 26, 2018 are not necessarily indicative of the operating results to be expected for the full fiscal year or future operating periods. The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, reserves and allowances; inventory valuation and purchase order accruals; valuation of goodwill and intangibles; restructuring reserves; product warranties; employee compensation and benefit accruals; stock-based compensation; loss contingencies; valuation of investment securities; income taxes and fair value measurements. Actual results could differ materially from those estimates. There have been no significant changes in our significant accounting policies as of and for the nine months ended January 26, 2018, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 28, 2017.
Accounting Standards on Transfers of Financial Assets	We account for the sales of these receivables as “true sales” as defined in the accounting standards on transfers of financial assets, as we are considered to have surrendered control of these financing receivables. Provided all other revenue recognition criteria have been met, we recognize product revenues for these arrangements, net of any payment discounts from financing transactions, upon product acceptance. We sold $62 million and $142 million of receivables during the nine months ended January 26, 2018 and January 27, 2017, respectively.
Revenue Recognition	Where we provide a guarantee for recourse leases, we defer revenues subject to the industry-specific software revenue recognition guidance and recognize revenues for non-software deliverables in accordance with our multiple deliverable revenue arrangement policy. In connection with certain recourse financing arrangements, we receive advance payments associated with undelivered elements that are subject to customer refund rights.
Debt	The portion of the financial arrangement that represents unearned services revenue is included in deferred revenue and financed unearned services revenue in our condensed consolidated balance sheets .
