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 software, systems and services to manage and store computer data. We enable enterprises, service providers, governmental organizations, and partners to envision, deploy and evolve their information technology environments and to reduce costs and risk while driving growth and success for their organizations. 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 year 2017, ending on April 28, 2017, is a 52-week year, with 13 weeks in each of its quarters. Fiscal year 2016, which ended on April 29, 2016, was a 53-week year, with 14 weeks in its first quarter and 13 weeks in each subsequent quarter. 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 29, 2016 contained in our Annual Report on Form 10-K. The results of operations for the three and nine months ended January 27, 2017 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 benefit accruals; stock-based compensation; loss contingencies; investment impairments; income taxes and fair value measurements. Actual results could differ materially from those estimates. Accounting Change – In the first quarter of fiscal 2017, we early adopted a new accounting standards update that the Financial Accounting Standards Board (FASB) issued in March 2016 that simplifies the accounting for certain aspects of stock-based payments to employees. The new standard requires that certain amendments relevant to us be applied using a modified-retrospective transition method by means of a cumulative-effect adjustment to retained earnings as of the beginning of the period in which the guidance is adopted. In connection with the adoption, we elected to account for forfeitures as they occur and the cumulative-effect impact of that change in accounting policy was a $7 million increase in retained earnings and a corresponding decrease in additional paid-in capital as of April 30, 2016. We also recorded a $3 million cumulative-effect adjustment decrease to retained earnings and a related decrease in deferred tax assets related to the forfeiture rate policy change on outstanding stock-based awards as of April 30, 2016. The standard also eliminates the requirement that excess tax benefits be realized before companies can recognize them. Accordingly, we recorded a $17 million cumulative-effect adjustment increase in retained earnings and an offsetting increase in deferred tax assets for previously unrecognized excess tax benefits as of April 30, 2016. The new standard eliminated the requirement to report excess tax benefits and certain tax deficiencies related to share-based payment transactions as additional paid-in capital. As a result, we recognized $18 million of tax deficiencies in our provision for income taxes, rather than additional paid–in capital, for the nine months ended January 27, 2017. We elected to report cash flows related to excess tax benefits on a prospective basis. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to our statements of cash flows since such cash flows have historically been presented as a financing activity. There have been no other significant changes in our significant accounting policies as of and for the nine months ended January 27, 2017, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 29, 2016.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Standards Not Yet Effective	2. Recent Accounting Standards Not Yet Effective 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. This new standard, as amended, will be effective for us in our first quarter of fiscal 2019, although early adoption is permitted. We expect to adopt this accounting standard update in the first quarter of fiscal 2019, and are currently evaluating the impact of this new standard update on our consolidated financial statements, as well as which transition method we intend to use. 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 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. 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 fiscal 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. In January 2017, the FASB issued an accounting standards update that simplifies the subsequent measurement of goodwill. This standard will be effective for us in fiscal 2021, although early adoption is permitted after January 1, 2017. Companies must apply this standard on a prospective basis. We intend to adopt this accounting standard update in the fourth quarter of fiscal 2017, and we do not expect it to have a material impact on our consolidated financial statements.

Investments Debt And Equity Securities [Abstract]
Financial Instruments and Fair Value Measurements	7. 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 27, 2017 April 29, 2016 Cost or Estimated Cost or Estimated Amortized Gross Unrealized Fair Amortized Gross Unrealized Fair Cost Gains Losses Value Cost Gains Losses Value Corporate bonds $ 1,411 $ 2 $ (3 ) $ 1,410 $ 1,370 $ 5 $ (1 ) $ 1,374 U.S. Treasury and government debt securities 688 — (3 ) 685 878 2 — 880 Foreign government debt securities 27 — — 27 35 — — 35 Commercial paper 426 — — 426 202 — — 202 Certificates of deposit 102 — — 102 98 — — 98 Mutual funds 30 — — 30 30 — — 30 Total debt and equity securities $ 2,684 $ 2 $ (6 ) $ 2,680 $ 2,613 $ 7 $ (1 ) $ 2,619 As of January 27, 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 27, 2017 and April 29, 2016, we have not made any adjustments to the prices obtained from our third-party pricing providers. Fair Value of Debt As of January 27, 2017 and April 29, 2016, the fair value of our long-term debt was approximately $1,511 million and $1,519 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.

Financing Arrangements Long-Term Debt The following table summarizes information relating to our long-term debt (in millions, except interest rates): January 27, 2017 April 29, 2016 Effective Effective Amount Interest Rate Amount Interest Rate 2.00% Senior Notes Due December 2017 $ 750 2.25 % $ 750 2.25 % 3.375% Senior Notes Due June 2021 500 3.54 % 500 3.54 % 3.25% Senior Notes Due December 2022 250 3.43 % 250 3.43 % Total principal amount 1,500 1,500 Unamortized discount and issuance costs (8 ) (10 ) Total senior notes 1,492 1,490 Less: Current portion of long-term debt (748 ) — Total long-term debt $ 744 $ 1,490 Senior Notes Our 3.375% Senior Notes, 2.00% Senior Notes and 3.25% Senior Notes, with a par value of $500 million, $750 million and $250 million, respectively, were issued in June 2014, December 2012 and December 2012, respectively. We collectively refer to such long-term debt as our Senior Notes. Interest on our Senior Notes is paid semi-annually on June 15 and December 15. 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 27, 2017, we were in compliance with all covenants associated with the Senior Notes. As of January 27, 2017, our aggregate future principal debt maturities are as follows (in millions): Fiscal Year Amount 2018 $ 750 Thereafter 750 Total $ 1,500 Commercial Paper Program and Credit Facility In December 2016, we entered into a commercial paper program (the Program), under which we may issue unsecured commercial paper notes. Amounts available under the Program 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 $600 million. The proceeds from the issuance of the notes will be used for general corporate purposes. As of January 27, 2017, we had commercial paper notes outstanding with an aggregate principal amount of $392 million, a weighted-average interest rate of 1.10% and maturities ranging from 20 days to 36 days. In connection with the Program, we entered into a new senior unsecured credit agreement with a syndicated group of lenders that expires on December 10, 2021, and we terminated our existing credit agreement that had been scheduled to expire on December 21, 2017. The new credit agreement provides a $600 million 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. 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 27, 2017, no borrowings or letters of credit were outstanding under this facility, and we were in compliance with all associated covenants. Short-Term Loan In February 2016, in connection with the SolidFire acquisition, we entered into a short-term loan of $870 million with a maturity of November 2, 2016. As of January 27, 2017, we have repaid the loan in full and have terminated the related loan agreement. 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 ranging from March 31, 2017 to December 31, 2017, unless terminated early by us. Due to the existence of a prohibited form of continuing involvement, these properties did not qualify for sale-leaseback accounting and as a result they have been accounted for as financing transactions under lease accounting standards. Under the financing method, until such time as the related leases are terminated, the assets will remain on our condensed consolidated balance sheets, and proceeds received by us from these transactions are reported as financing obligations. During the three months ended January 27, 2017, we terminated one of the leases, ending our continuing involvement with the related properties. As a result, we recorded a non-cash sale of properties having a net book value of $9 million, the extinguishment of $19 million of associated financing obligations, and a gain of $10 million. As of January 27, 2017, the balance of the remaining financing obligations, which relate to properties whose leases we expect to terminate in December 2017, was $130 million. At the end of the leaseback period, or when our continuing involvement under the leaseback agreement ends, this transaction will be reported as a non-cash sale and extinguishment of financing obligations, and the difference between the then net book value of the properties and the unamortized balance of the financing obligations will be recognized as a gain.

Stock Repurchase Program As of January 27, 2017, our Board of Directors has authorized the repurchase of up to $9.6 billion of our common stock. Under this program, which we may suspend or discontinue at any time, we may purchase shares of our outstanding common stock through open market and privately negotiated transactions at prices deemed appropriate by our management. The following table summarizes activity related to this program for the nine months ended January 27, 2017 (in millions, except per share amounts): Number of shares repurchased 18 Average price per share $ 31.19 Aggregate purchase price $ 576 Remaining authorization at end of period $ 924 The aggregate purchase price of our stock repurchases for the nine months ended January 27, 2017 consisted of $576 million of open market purchases, of which $305 million and $271 million were allocated to additional paid-in capital and retained earnings, respectively. Since the May 13, 2003 inception of our stock repurchase program through January 27, 2017, we repurchased a total of 266 million shares of our common stock at an average price of $32.74 per share, for an aggregate purchase price of $8.7 billion.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	10. 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 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 the agreement. 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 27, 2017 and April 29, 2016. We did not recognize any gains and 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 27, 2017 April 29, 2016 Cash Flow Hedges Forward contracts purchased $ 128 $ 99 Balance Sheet Contracts Forward contracts sold $ 166 $ 160 Forward contracts purchased $ 377 $ 396 The effect of derivative instruments designated as cash flow hedges recognized in net revenues on our condensed consolidated statements of operations is presented in the condensed consolidated statements of comprehensive income and Note 9 – Stockholders’ Equity.

Restructuring And Related Activities [Abstract]
Restructuring Charges	11. Restructuring Charges During the three months ended January 27, 2017, we announced a restructuring plan (the November 2016 Plan) to streamline our core business and decrease operating expenses, which included a reduction in our global workforce of approximately 6%. We expect to complete the November 2016 Plan by the fourth quarter of fiscal 2017 with no significant additional charges. During fiscal 2016, management approved two restructuring actions to streamline our business, eliminate costs and redirect resources to our highest return activities. These actions consisted of the May 2015 Plan and the March 2016 Plan, under which we reduced our global workforce by an aggregate of approximately 14%. These plans have been completed as of January 27, 2017. Restructuring charges related to each of these plans consisted primarily of employee severance-related costs. Activities related to our restructuring plans are summarized as follows (in millions): Nine Months Ended Nine Months Ended January 27, 2017 January 29, 2016 November 2016 Plan March 2016 Plan Total May 2015 Plan Balance at beginning of period $ — $ 45 $ 45 $ — Net charges 52 — 52 28 Cash payments (27 ) (45 ) (72 ) (28 ) Balance at end of period $ 25 $ — $ 25 $ —

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes Our effective tax rates for the periods presented were as follows: Nine Months Ended January 27, 2017 January 29, 2016 Effective tax rates 23.5 % 16.8 % 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 U.S. statutory tax rate. The differences in effective tax rates for the nine months ended January 27, 2017 and January 29, 2016 were primarily a result of differences in year-to-date profits before tax and the impacts of discrete events as described below. During the first quarter of fiscal 2017, we adopted a new accounting standard that simplifies stock-based compensation income tax accounting and presentation within the financial statements. During the nine months ended January 27, 2017, we recorded discrete charges of $18 million following the post-adoption rules which require that all excess tax benefits and deficiencies from stock-based compensation be recognized as a component of income tax expense. See Note 1 – Description of Business and Significant Accounting Policies for more details regarding the adoption of this accounting standard. In June 2015, the Internal Revenue Service (IRS) signed a closing agreement on our fiscal 2008 to 2010 transfer pricing arrangements and, in October 2015, completed the examination of our fiscal 2008 to 2010 income tax returns. During the nine months ended January 29, 2016, we recorded discrete charges totaling $23 million, attributable to the audit settlements and related re-measurement of uncertain tax positions for tax years subject to future audits. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions): Nine Months Ended January 27, 2017 January 29, 2016 Balance at beginning of period $ 216 $ 272 Additions based on tax positions related to the current year 5 13 Additions for tax positions of prior years 6 21 Decreases for tax positions of prior years — (38 ) Settlements (12 ) (52 ) Balance at end of period $ 215 $ 216 As of January 27, 2017, we had $215 million of gross unrecognized tax benefits, of which $147 million has been recorded in other long-term liabilities. Unrecognized tax benefits of $157 million, including penalties, interest and indirect benefits, would affect our provision for income taxes if recognized. We are currently undergoing income tax audits in the United States (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 federal income 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 European Court of Justice. 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 Reporting [Abstract]
Segment, Geographic, and Significant Customer Information	14. 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 27, 2017 January 29, 2016 January 27, 2017 January 29, 2016 United States, Canada and Latin America (Americas) $ 767 $ 752 $ 2,271 $ 2,316 Europe, Middle East and Africa (EMEA) 460 456 1,243 1,301 Asia Pacific (APAC) 177 178 524 549 Net revenues $ 1,404 $ 1,386 $ 4,038 $ 4,166 Americas revenues consist of sales to Americas commercial and U.S. public sector markets.

Compensation And Retirement Disclosure [Abstract]
Postretirement Health Care Plan	15. Postretirement Health Care Plan Certain of our executive officers are eligible to participate in our Executive Retirement Medical Plan (the ERM Plan). The ERM Plan provides, upon retirement, medical benefits beyond the COBRA maximum benefit period to a defined group of senior executives based on minimum age, years of service and position. The ERM Plan is unfunded as of April 29, 2016 and January 31, 2017, and there is no minimum funding requirement under the ERM Plan. In November 2016, we made certain amendments to the ERM Plan, which prior to amendment, provided group health insurance benefits to eligible retirees. Effective January 1, 2017, the amended ERM Plan provides each eligible retiree with a capped reimbursement of premiums for the period from January 1, 2017 through December 31, 2019. During the period from December 31, 2019 through December 31, 2021, participants in the ERM Plan will be eligible to receive a lump sum cash payment equal to two years of projected health care costs, or a prorated portion thereof, pursuant to the methodology set forth in the ERM Plan. Such payment will be made by us outside the ERM Plan as the ERM Plan is expected to terminate on December 31, 2019. These plan amendments resulted in a prior service credit adjustment, with the following impacts to our condensed consolidated financial statements in the three and nine months ended January 27, 2017 (in millions): Decrease in other long-term liabilities $ 23 Decrease in deferred tax assets $ 9 Other comprehensive income, net of taxes $ 14

Commitments and Contingencies

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 $227 million as of January 27, 2017. 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 manufacture of our products. A significant portion of our reported purchase commitments arising from these agreements consist of firm, non-cancelable, and unconditional commitments. As of January 27, 2017, we had $313 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 27, 2017 and April 29, 2016, such liability amounted to $11 million and $7 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 27, 2017, we had $20 million in construction related obligations and $220 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 $142 million and $153 million of receivables during the nine months ended January 27, 2017 and January 29, 2016, 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. As of January 27, 2017 and April 29, 2016, 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 27, 2017, we have not been required to make any significant 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.

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 year 2017, ending on April 28, 2017, is a 52-week year, with 13 weeks in each of its quarters. Fiscal year 2016, which ended on April 29, 2016, was a 53-week year, with 14 weeks in its first quarter and 13 weeks in each subsequent quarter. 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 29, 2016 contained in our Annual Report on Form 10-K. The results of operations for the three and nine months ended January 27, 2017 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 benefit accruals; stock-based compensation; loss contingencies; investment impairments; income taxes and fair value measurements. Actual results could differ materially from those estimates.
Accounting Change	Accounting Change – In the first quarter of fiscal 2017, we early adopted a new accounting standards update that the Financial Accounting Standards Board (FASB) issued in March 2016 that simplifies the accounting for certain aspects of stock-based payments to employees. The new standard requires that certain amendments relevant to us be applied using a modified-retrospective transition method by means of a cumulative-effect adjustment to retained earnings as of the beginning of the period in which the guidance is adopted. In connection with the adoption, we elected to account for forfeitures as they occur and the cumulative-effect impact of that change in accounting policy was a $7 million increase in retained earnings and a corresponding decrease in additional paid-in capital as of April 30, 2016. We also recorded a $3 million cumulative-effect adjustment decrease to retained earnings and a related decrease in deferred tax assets related to the forfeiture rate policy change on outstanding stock-based awards as of April 30, 2016. The standard also eliminates the requirement that excess tax benefits be realized before companies can recognize them. Accordingly, we recorded a $17 million cumulative-effect adjustment increase in retained earnings and an offsetting increase in deferred tax assets for previously unrecognized excess tax benefits as of April 30, 2016. The new standard eliminated the requirement to report excess tax benefits and certain tax deficiencies related to share-based payment transactions as additional paid-in capital. As a result, we recognized $18 million of tax deficiencies in our provision for income taxes, rather than additional paid–in capital, for the nine months ended January 27, 2017. We elected to report cash flows related to excess tax benefits on a prospective basis. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to our statements of cash flows since such cash flows have historically been presented as a financing activity. There have been no other significant changes in our significant accounting policies as of and for the nine months ended January 27, 2017, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 29, 2016.
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 $142 million and $153 million of receivables during the nine months ended January 27, 2017 and January 29, 2016, 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 .
