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 2020 and 2019, ending on April 24, 2020, and April 26, 2019, 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, cash flows and stockholders’ equity 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 26, 2019 contained in our Annual Report on Form 10-K. The results of operations for the three and six months ended October 25, 2019 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; investment impairments; income taxes and fair value measurements. Actual results could differ materially from those estimates. Accounting Changes 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 (ROU) asset and corresponding lease liability, measured at the present value of the lease payments. In the first quarter of fiscal 2020, we adopted this new standard using the modified retrospective approach, electing the optional transition approach of not adjusting our comparative period financial statements for the impacts of adoption. We also elected the package of practical expedients that did not require us to reassess existing leases under the new guidance, and the practical expedient to not separate lease and non-lease components for all leases. Adoption of the new standard on April 27, 2019 resulted in the recognition of approximately $149 million of operating lease ROU assets, net of deferred rent and lease restructuring liabilities, $158 million of lease liabilities, and a cumulative-effect adjustment to retained earnings of $6 million on our condensed consolidated balance sheets. Adoption of the standard did not have a material impact on our condensed consolidated statements of operations or condensed consolidated statements of cash flows. Additional information is presented below and in Note 9 – Leases. Leases − We determine if an arrangement is or contains a lease at inception, and we classify leases as operating or finance leases at commencement. In our condensed consolidated balance sheets, operating lease ROU assets are included in other non-current assets, while finance lease ROU assets are included in property and equipment, net. Lease liabilities for both types of leases are included in accrued expenses and other long-term liabilities. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments over that term. Operating and finance lease ROU assets and liabilities are recognized at commencement based on the present value of lease payments over the lease term. ROU assets also include any lease payments made prior to lease commencement and exclude lease incentives. The lease term is the noncancelable period of the lease and includes options to extend or terminate the lease when it is reasonably certain that an option will be exercised. As the rate implicit in our leases is typically not readily determinable, in computing the present value of lease payments we generally use our incremental borrowing rate based on information available at the commencement date. Variable lease payments not dependent on an index or rate are expensed as incurred and not included within the calculation of ROU assets and lease liabilities. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We do not separate non-lease components from lease components for any class of leases, and we do not recognize ROU assets and lease liabilities for leases with a lease term of twelve months or less. There have been no other significant changes in our significant accounting policies as of and for the six months ended October 25, 2019, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended April 26, 2019.

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 2020 and 2019, ending on April 24, 2020, and April 26, 2019, 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, cash flows and stockholders’ equity for the interim periods presented.

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 26, 2019 contained in our Annual Report on Form 10-K. The results of operations for the three and six months ended October 25, 2019 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; investment impairments; income taxes and fair value measurements.
