Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation and preparation	Basis of presentation and preparation The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of October 3, 2020 has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual financial statements. They should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended October 3, 2020 (the “Annual Report”), filed with the SEC on November 23, 2020. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations, and its cash flows for the interim periods presented. The results of operations for the three and nine months ended July 3, 2021 are not necessarily indicative of the results to be expected for the full fiscal year or any other period. The Company operates on a 52- week or 53- week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the fourth quarter of the Company’s fiscal year ended October 3, 2020 and will reoccur in the fiscal year ending October 3, 2026. The nine months ended July 3, 2021 and June 27, 2020 spanned 39 weeks each. As used in this Quarterly Report on Form 10-Q, “fiscal 2021” refers to the fiscal year ending October 2, 2021 and “fiscal 2020” refers to the fiscal year ended October 3, 2020.
Use of estimates and judgment	Use of estimates and judgments The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends. In March 2020, the outbreak of the novel coronavirus (COVID-19) was declared a pandemic. While the nature of the situation is dynamic, the Company has considered the impact when developing its estimates and assumptions noted above. Actual results and outcomes may differ from management's estimates and assumptions.
Recently adopted accounting pronouncements and recent accounting pronouncements pending adoption	Recently adopted accounting pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, and it subsequently issued amendments to the initial guidance (collectively referred to as "Topic 326"), which provide a new impairment model that requires measurement and recognition of expected credit losses for most financial assets and certain other instruments, including accounts receivable. The Company adopted this standard effective October 4, 2020, using a modified retrospective approach. Under the new standard, the allowance for credit losses is based on the Company's assessment of collectability of accounts, including consideration of the age of invoices, each customer's expected ability to pay and collection history, customer-specific information and current economic conditions that may impact a customer's ability to pay. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This standard resolves the diversity in practice concerning whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Accounting Standards Codification 606, Revenue from Contracts with Customers ("Topic 606"). This standard specifies when a participant is a customer in a collaboration, adds guidance for unit of account to align with Topic 606 and provides presentation guidance for collaborative arrangements. The Company adopted this standard in the first quarter of fiscal 2021. The adoption did not have a material impact on the Company's consolidated financial statements. Recent accounting pronouncements pending adoption In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard simplifies the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification Topic 740 ("ASC 740") as well as by improving consistent application of the topic by clarifying and amending existing guidance. This standard is effective for the Company in the first quarter of fiscal 2022, with early adoption permitted. The Company is currently evaluating the timing of adoption and impact on the Company's consolidated financial statements.
