Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Winnebago Industries, Inc. and its wholly owned subsidiaries. Significant intercompany account balances and transactions have been eliminated. The use of the terms "Winnebago Industries," "Winnebago", and "the Company" in this Quarterly Report on Form 10-Q, unless the context otherwise requires, refers to Winnebago Industries, Inc. and its wholly owned subsidiaries. The interim unaudited consolidated financial statements included herein are prepared pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The information furnished in these consolidated financial statements includes normal recurring adjustments, unless noted otherwise in the Notes to Financial Statements, and reflects all adjustments that are, in management’s opinion, necessary for a fair presentation of such financial statements. The consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). GAAP requires us to make estimates and assumptions that affect amounts reported. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations. The consolidated financial statements included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended August 29, 2020 filed with the SEC. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. Fiscal Period The Company has a 5-4-4 quarterly accounting cycle with the fiscal year ending on the last Saturday in August. Fiscal 2021 ending on August 28, 2021 will consist of 52 weeks. Fiscal 2020 ended on August 29, 2020 consisted of 52 weeks. Cash and Cash Equivalents Cash and cash equivalents represent cash, demand deposits and highly liquid investments with original maturities of three months or less that are not legally restricted. Cash equivalents are recorded at cost, which approximates fair value. Accounts at each banking institution are insured by the Federal Deposit Insurance Corporation up to $250,000, while the remaining balances are uninsured. Subsequent Events In preparing the accompanying unaudited consolidated financial statements, the Company evaluated subsequent events for potential recognition and disclosure through the date of this filing noting no material subsequent events. CARES Act The Coronavirus Aid, Relief, and Economic Security ("CARES") Act was signed into law on March 27, 2020 to help alleviate the impact of the COVID-19 pandemic in the U.S. The Company is taking advantage of the employer payroll tax deferral offered by the CARES Act, which allows the Company to defer the payment of employer payroll taxes for the period from March 27, 2020 to December 31, 2020. The deferred employer payroll tax liability as of May 29, 2021 was $16,223 and will be payable in equal installments in December 2021 and December 2022. The Company also took advantage of a tax credit granted to companies under the CARES Act who continued to pay their employees when operations were fully or partially suspended. The refundable tax credit available through the end of the third quarter of Fiscal 2020 reflected in cost of goods sold on the Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) was approximately $3,999. The entire amount is expected to be received by the end of calendar year 2021. As of May 29, 2021, $3,202 remains outstanding within other current assets on the Consolidated Balance Sheets. Recently Adopted Accounting Pronouncements The Company adopted Accounting Standards Codification ("ASC") Topic 326, Financial Instruments—Credit Losses, which changes the accounting for credit losses on instruments measured at amortized costs, such as accounts receivables and deposits by adding an impairment model that is based on expected losses rather than incurred losses. An entity will recognize as an allowance its estimate of expected credit losses, which is believed to result in more timely recognition of such losses as the standard eliminates the probable initial recognition threshold. The Company adopted the new standard using the modified retrospective approach, which involves recognizing the cumulative effect of initial adoption of Topic 326 as an adjustment to its opening retained earnings as of August 30, 2020. As a result, the Company did not adjust comparative period financial information for periods before the effective date. No incremental allowance for credit losses has been recognized during the nine months ended May 29, 2021 as a result of the adoption. The adoption of this standard did not have a material impact on the Company’s financial condition, results of operations or disclosures. Recently Issued Accounting Pronouncements In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) which reduces the number of models used to account for convertible instruments, amends diluted earnings per share ("EPS") calculations for convertible instruments, and amends the requirements for a contract (or embedded derivative) that is potentially settled in an entity's own shares to be classified in equity. Certain disclosure requirements were also added to increase transparency and decision-usefulness regarding a convertible instrument's terms and features. Additionally, the if-converted method for including convertible instruments must be used in diluted EPS as opposed to the treasury stock method. The new guidance is effective for annual reporting periods beginning after December 15, 2021, which is the Company's Fiscal 2023. Early adoption is permitted using either a modified retrospective or full retrospective approach. The Company expects to adopt the new guidance in the first quarter of Fiscal 2023 and has not yet evaluated the impact the adoption of this guidance will have on its financial condition, results of operations or disclosures; however, the new guidance is expected to change the Company's diluted EPS reporting. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting, which provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by this guidance apply only to contracts, hedging relationships, and other transactions that reference the London interbank offered rate (“LIBOR”) or another reference rate expected to be discontinued as a result of reference rate reform. This guidance is not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. The guidance can be applied immediately through December 31, 2022. The Company will adopt this standard when LIBOR is discontinued and does not expect a material impact to its financial condition, results of operations or disclosures based on the current debt portfolio and capital structure. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions to Topic 740's general principles, improves consistent application and simplifies its application. The standard is effective for annual reporting periods beginning after December 15, 2020, which is the Company's Fiscal 2022, including interim periods within those annual reporting periods. The Company expects to adopt the new guidance in the first quarter of Fiscal 2022, and does not expect a material impact to its financial condition, results of operations or disclosures.
