Winnebago Industries, Inc. is one of the leading North American manufacturers of recreation vehicles ("RV"s) and marine products with a diversified portfolio used primarily in leisure travel and outdoor recreational activities. We produce our motorhome units in Iowa and Indiana; our towable units in Indiana; and our marine units in Indiana and Florida. We distribute our RV and marine products primarily through independent dealers throughout the U.S. and Canada, who then retail the products to the end consumer. We also distribute our marine products internationally through independent dealers, who then retail the products to the end consumer. Other products manufactured by us consist primarily of original equipment manufacturing parts for other manufacturers and commercial vehicles.

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," "we," "our," and "us" in this Annual Report on Form 10-K, unless the context otherwise requires, refer to Winnebago Industries, Inc. and its wholly-owned subsidiaries.

We have a 5-4-4 quarterly accounting cycle with the fiscal year ending on the last Saturday in August. Fiscal 2022 refers to the fiscal year ended August 27, 2022, Fiscal 2021 refers to the fiscal year ended August 28, 2021, and Fiscal 2020 refers to the fiscal year ended August 29, 2020. The financial statements presented are all 52-week fiscal periods.

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting years. Actual results could differ from those estimates.

We record an allowance using a model to reduce receivables by the expected credit loss and consider factors such as financial condition of the dealer, specific collection issues, current and expected economic conditions, and other factors that may impact our ability to collect. If there is a deterioration of a dealer's financial condition, if we become aware of additional information related to credit worthiness, or if future actual default rates on receivables differ from those currently anticipated, we may adjust the allowance for doubtful accounts, which would affect earnings in the period the adjustments are made.

Generally, inventories are stated at the lower of cost or net realizable value determined under the First-in, First-out basis ("FIFO"), except for the Winnebago Motorhome operating segment which is determined using the Last-in, First-out ("LIFO") basis. Manufacturing cost includes materials, labor, and overhead. Unallocated overhead and abnormal costs are expensed as incurred.

Goodwill is tested for impairment at least annually, during the fourth quarter and whenever events occur or circumstances change that would indicate the carrying value may not be recoverable. Impairment testing for goodwill is performed at a reporting unit level and all goodwill is assigned to a reporting unit. Our reporting units are the same as the operating segments as defined in Note 3.

We have the option to first assess qualitative factors to determine whether the fair value of a reporting unit is “more likely than not” less than its carrying value. If it is more likely than not that an impairment has occurred, we then perform the quantitative goodwill impairment test. If we perform the quantitative test, the carrying value of the reporting unit is compared to an estimate of the reporting unit’s fair value to identify impairment. The estimate of the reporting unit’s fair value involves significant unobservable inputs (Level 3 inputs). The fair value is determined by a blend of the income approach (discounted future cash flow) and market approach (guideline public company) using current industry information. In determining the estimated future cash flow, we consider and apply certain estimates and judgments, including current and projected future levels of income based on management plans, business trends, prospects, market and economic conditions, and market-participant considerations. If the quantitative assessment of goodwill impairment fails, an impairment loss equal to the amount that a reporting unit's carrying value exceeds its fair value will be recognized.

During the fourth quarter of Fiscal 2022, we completed the annual goodwill impairment analysis. We elected to rely on a qualitative assessment for the Grand Design, Newmar, and Barletta reporting units, and performed a quantitative analysis for the Chris-Craft reporting unit. No impairment was identified for the years ended August 27, 2022, August 28, 2021, or August 29, 2020.

We have indefinite-lived intangible assets for trade names related to Newmar within the Motorhome segment, Grand Design within the Towable segment, and Chris-Craft and Barletta within the Marine segment. Annually in the fourth quarter, or if conditions indicate an interim review is necessary, we test trade names for impairment. We have the option to first assess qualitative factors to determine whether the fair value of a trade name is “more likely than not” less than its carrying value. If it is more likely than not that an impairment has occurred, we then perform the quantitative impairment test. If we perform the quantitative test, the carrying value of the asset is compared to an estimate of its fair value to identify impairment. The fair value is determined by the relief-from-royalty method, which requires significant judgment. Actual results may differ from assumed and estimated amounts utilized in the analysis. If we conclude an impairment exists, the asset's carrying value will be written down to its fair value.

During the fourth quarter of Fiscal 2022, we completed the annual impairment analysis. We elected to rely on a qualitative assessment for the Grand Design, Newmar, and Barletta trade names, and performed a quantitative analysis for the Chris-Craft trade name. No impairment was identified for the years ended August 27, 2022, August 28, 2021, or August 29, 2020.

Long-lived assets, which include property, plant and equipment, definite-lived intangible assets subject to amortization, primarily the dealer network, and right-of-use assets are assessed for impairment whenever events or changes in circumstances such as asset utilization, physical change, legal factors or other matters indicate the carrying value of those assets may not be recoverable from future undiscounted cash flows. The impairment test involves comparing the carrying amount of the asset to the forecasted undiscounted future cash flows generated by that asset. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. In the event the carrying amount of the asset exceeds the undiscounted future cash flows generated by that asset and the carrying amount is not considered recoverable, an impairment exists. An impairment loss is measured as the excess of the asset’s carrying amount over its fair value and is recognized in the statement of income in the period that the impairment occurs. The reasonableness of the useful lives of the asset and other long-lived assets is regularly evaluated.

Generally, we self-insure a portion of health insurance, product liability claims, and workers' compensation. Under these plans, liabilities are recognized for claims incurred, including those incurred but not reported. We use third party administrators and actuaries who use historical claims experience and various state statutes to assist in the determination of the accrued liability balance. We have a $75.0 million insurance policy that includes a self-insured retention for product liability of $1.0 million per occurrence and $2.0 million in aggregate per policy year. Our self-insured health insurance policy includes an individual retention of $0.5 million per occurrence. We maintain excess liability insurance with outside insurance carriers to minimize the risks related to catastrophic claims in excess of self-insured positions for product liability, health insurance, and personal injury matters. Any material change in the aforementioned factors could have an adverse impact on operating results. Balances are included within self-insurance (accrued expenses) on the Consolidated Balance Sheets.

In preparing these financial statements, we are required to estimate the income taxes in each of the jurisdictions in which we operate. This process involves estimating the current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included on the Consolidated Balance Sheets. We then assess the likelihood that the deferred tax assets will be realized based on future taxable income and, to the extent that recovery is not likely, a valuation allowance is established. To the extent we establish a valuation allowance or change this allowance in a period, an expense or a benefit is included within the tax provision on the Consolidated Statements of Income and Comprehensive Income.

Our primary source of revenue is generated through the sale of non-motorized towable units, motorhome units, and marine units to our independent dealer network (customers). Unit revenue is recognized at a point-in-time when the performance obligation is satisfied and control of the promised goods or services is transferred to the customer, which generally occurs when the unit is shipped to or picked-up from the manufacturing facilities by the customer. Control refers to the ability of the customer to direct the use of, and obtain substantially all of, the remaining benefits from the goods or services. We recognize revenue based on an amount that reflects the transaction price consideration that we expect to receive in exchange for those goods or services. Our transaction price consideration is fixed, unless otherwise disclosed as variable consideration. The amount of consideration received and recorded to revenue can vary with changes in marketing incentives and discounts offered to customers. These marketing incentives and discounts are considered variable consideration. We adjust the estimate of revenue at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. Our payment terms are typically before or on delivery, and do not include a significant financing component.

Net revenue includes shipping and handling charges billed directly to customers, and we also generate income through the sale of certain parts and services, acting as the principal in these arrangements. We have made an accounting policy election to account for any shipping and handling costs that occur after the transfer of control as a fulfillment cost that is accrued when control is transferred. We also have made an accounting policy election to exclude from revenue sales and usage-based taxes collected.

Our contracts include some incidental items that are immaterial in the context of the contract. We have made an accounting policy election to not assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer. Warranty obligations associated with the sale of a unit are assurance-type warranties that are a guarantee of the unit’s intended functionality and, therefore, do not represent a distinct performance obligation within the context of the contract. Contract costs incurred related to the sale of manufactured units are expensed at the point-in-time when the related revenue is recognized.

The revenue standard requirements are applied to a portfolio of contracts (or performance obligations) with similar characteristics for transactions where it is expected that the effects on the financial statements of applying the revenue recognition guidance to the portfolio would not differ materially from applying this guidance to the individual contracts (or performance obligations) within that portfolio.

Advertising costs, which consist primarily of trade shows and online content, were $23.3 million, $11.6 million, and $12.5 million in Fiscal 2022, 2021, and 2020, respectively. Advertising costs are included in selling, general, and administrative expenses and are expensed as incurred on the Consolidated Statements of Income and Comprehensive Income.

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. We took advantage of the employer payroll tax deferral offered by the CARES Act, which allowed us 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 was $8.1 million and $16.2 million as of August 27, 2022 and August 28, 2021, respectively. The deferred employer payroll tax liability paid in Fiscal 2022 was $8.1 million. We 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 our third quarter of Fiscal 2020 reflected in cost of goods sold on the Consolidated Statements of Income and Comprehensive Income was approximately $4.0 million. The entire amount is expected to be received by the end of calendar year 2022. As of August 27, 2022, $0.8 million remains outstanding within other current assets on the Consolidated Balance Sheets.

Accounting Standards Update ("ASU") Topic 740, Income Taxes: Simplifying the Accounting for Income Taxes, was adopted in the first quarter of Fiscal 2022. The new standard eliminates certain exceptions to Topic 740's general principles, improves consistent application and simplifies its application. We adopted the new guidance in the first quarter of Fiscal 2022, and there was not a material impact to our financial condition, results of operations or disclosures.
