Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation and Use of Estimates The accompanying Consolidated Financial Statements are unaudited and have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In our opinion, they include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the SEC's rules and regulations for interim reporting. These Consolidated Financial Statements should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended January 2, 2021 ("2020 10-K"). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. We base our estimates and judgments on historical experience, knowledge of current conditions, and our beliefs of what could occur in the future considering available information. While we believe that our estimates, assumptions, and judgments are reasonable, they are based on information available when made, and because of the uncertainty inherent in these matters, actual results may differ materially from these estimates under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. We describe our accounting methods and practices in more detail in our 2020 10-K. There have been no changes to the significant accounting policies, procedures, or general information described in our 2020 10-K that have had a material impact on our consolidated financial statements and related notes. Certain prior year balances have been reclassified to conform to the current year’s presentation.
Fiscal Period, Policy [Policy Text Block] | Fiscal Reporting Periods We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal 2021 will be a 52-week year and will end on January 1, 2022, and our fiscal 2020 was a 53-week year that ended January 2, 2021. Our third quarter of fiscal 2021 and third quarter of fiscal 2020 ended on October 2, 2021 and September 26, 2020, respectively. All references to quarterly or nine months ended financial results are references to the results for the relevant 13-week or 39-week fiscal period.
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentrations of Risk Potential exposure to concentrations of risk may impact revenue and accounts receivable. Distributors have historically accounted for a significant portion of our total revenue. Revenue attributable to distributors as a percentage of total revenue was 90% and 82% for the third quarter of fiscal 2021 and 2020, respectively, and 88% and 81% for the nine months ended October 2, 2021 and September 26, 2020, respectively. Distributors also account for a substantial portion of our net accounts receivable. Our two largest distributors accounted for 55% and 29% of net accounts receivable at October 2, 2021 and 47% and 45% of net accounts receivable at January 2, 2021.
