Recently adopted authoritative guidance Leases. In February 2016, the Financial Accounting Standards Board (FASB) issued new guidance on lease accounting which requires lessees to recognize assets and liabilities on their balance sheet for the rights and obligations created by operating leases and also requires disclosures designed to give users of financial statements information on the amount, timing, and uncertainty of cash flows arising from leases. Most prominent among the changes in the standard is the recognition of right-of-use (ROU) assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. On March 30, 2019, the first day of our fiscal 2020, we adopted the new guidance using the alternative modified retrospective transition method under which we continue to apply the legacy lease accounting guidance, including its disclosure requirements, in comparative periods prior to fiscal 2020. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard that allowed us not to reassess (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. We currently do not have any finance leases. We combine the lease and non-lease components in determining the operating lease assets and liabilities. The adoption of the new lease accounting standard resulted in the recognition of ROU assets and lease liabilities of $182 million and $209 million, respectively, as of March 30, 2019 related to our operating leases. The adoption of the standard also resulted in elimination of deferred rent liabilities of $17 million, as of March 30, 2019, which are now recorded as a reduction of the ROU assets. The standard did not have an impact on our consolidated statements of operations or statements of cash flows. Recently issued authoritative guidance not yet adopted Credit Losses. In June 2016, the FASB issued new authoritative guidance on credit losses which changes the impairment model for most financial assets and certain other instruments. For trade receivables and other instruments, we will be required to use a new forward-looking “expected loss” model. Additionally, for available-for-sale debt securities with unrealized losses, we will measure credit losses in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The standard will be effective for us in our first quarter of fiscal 2021. We are currently evaluating the impact of the adoption of this guidance on our Consolidated Financial Statements. Internal-Use Software. In August 2018, the FASB issued new guidance that clarifies the accounting for implementation costs in a cloud computing arrangement. The new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard will be effective for us in our first quarter of fiscal 2021, with early adoption permitted. We are currently evaluating the adoption date and the impact of the adoption of this guidance on our Consolidated Financial Statements and disclosures. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (GAAP) in the United States of America (U.S.) for interim financial information. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 29, 2019. The results of operations for the three months ended July 5, 2019 are not necessarily indicative of the results expected for the entire fiscal year.

Fiscal accounting year

We have a 52/53-week fiscal year ending on the Friday closest to March 31. Unless otherwise stated, references to three-month periods in this report relate to fiscal periods ended July 5, 2019 and June 29, 2018. The three months ended July 5, 2019 consisted of 14 weeks, whereas the three months ended June 29, 2018 consisted of 13 weeks. Our 2020 fiscal year consists of 53 weeks and ends on April 3, 2020.

Use of estimates

The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of stand-alone selling price for performance obligations, valuation of business combinations including acquired intangible assets and goodwill, loss contingencies, valuation of stock-based compensation, and the recognition and measurement of current and deferred income taxes, including the measurement of uncertain tax positions. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the Condensed Consolidated Financial Statements.

Significant accounting policies

There have been no material changes to our significant accounting policies as of and for the three months ended July 5, 2019, except for those noted in Note 2 and Note 4, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended March 29, 2019.
