Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (GAAP) in the United States of America 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 included in our Annual Report on Form 10-K for the fiscal year ended April 3, 2020. The results of operations for the six months ended October 2, 2020 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 and six-month periods in this report relate to fiscal periods ended October 2, 2020 and October 4, 2019. The three and six months ended October 2, 2020 consisted of 13 and 26 weeks, respectively, whereas the three and six months ended October 4, 2019 consisted of 13 and 27 weeks, respectively. Our 2021 fiscal year consists of 52 weeks and ends on April 2, 2021.
Use of estimates	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, valuation of business combinations including acquired intangible assets and goodwill, loss contingencies, the recognition and measurement of current and deferred income taxes, including the measurement of uncertain tax positions, and valuation of assets and liabilities and results of operations of our discontinued operations. 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 from such estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the COVID-19 pandemic, and such differences may be material to the Condensed Consolidated Financial Statements.
Recently accounting standards	Recently adopted authoritative guidance Credit Losses. In June 2016, the Financial Accounting Standards Board (FASB) issued new authoritative guidance on credit losses which changes the impairment model for most financial assets and certain other instruments. On April 4, 2020, the first day of our fiscal 2021, we adopted the new guidance using the modified retrospective transition method. Upon adoption, we utilized a new forward-looking “expected loss” model to replace the incurred loss impairment model for our accounts receivable and other financial assets. Additionally, for available-for-sale debt securities with unrealized losses, we discontinued using the concept of “other than temporary” impairment and recognized the estimated credit loss as allowances. The cumulative effect from the adoption of this guidance was immaterial to our Condensed 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. On April 4, 2020, we adopted the new guidance prospectively. The adoption of this guidance did not have a material impact on our Condensed Consolidated Financial Statements. Recently issued authoritative guidance not yet adopted Income taxes. In December 2019, the FASB issued new guidance that simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The guidance also clarifies and amends existing guidance to improve consistent application. The standard will be effective for us in our first quarter of fiscal 2022, with early adoption permitted. We are currently evaluating the adoption date and the impact of the adoption of this guidance on our Condensed Consolidated Financial Statements and disclosures. Debt with Conversion and Other options. In August 2020, the FASB issued new guidance that simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments. The new guidance removes from GAAP the separation models for convertible debt with embedded conversion features. As a result, after adopting the guidance, entities will no longer separately present embedded conversion features in equity. Instead, they will account for the convertible debt wholly as debt. The new guidance also requires use of the if-converted method when calculating the dilutive impact of convertible debt on earnings per share. The standard will be effective for us in our first quarter of fiscal 2023, with early adoption permitted beginning in the first quarter of fiscal 2022. It may be applied retrospectively to each prior period presented or retrospectively with cumulative effect recognized in retained earnings as of the date of adoption. We are currently evaluating the adoption date and the impact of the adoption of this guidance on our Condensed 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.
