Guarantees [Abstract]
Warranties	7. WARRANTIES We offer warranties for the limited number of specific products we manufacture. Our warranty terms generally range from one to three years. We estimate the cost to perform under the warranty obligation and recognize this estimated cost at the time of the related product sale. We record expense related to our warranty obligations as cost of sales in our consolidated statements of comprehensive income (loss). Each quarter, we assess actual warranty costs incurred on a product-by-product basis and compare the warranty costs to our estimated warranty obligation. With respect to new products, estimates are based generally on knowledge of the products and warranty experience, if a sufficient history exists. Warranty reserves are established for costs that are expected to be incurred after the sale and delivery of products under warranty. Warranty reserves are included in accrued liabilities on our consolidated balance sheets. The warranty reserves are determined based on known product failures, historical experience and other available evidence. Warranty reserves were approximately $0.4 million as of November 28, 2020 and $0.5 million as of May 30, 2020.

We offer warranties for the limited number of specific products we manufacture. Our warranty terms generally range from one to three years.

We estimate the cost to perform under the warranty obligation and recognize this estimated cost at the time of the related product sale. We record expense related to our warranty obligations as cost of sales in our consolidated statements of comprehensive income (loss). Each quarter, we assess actual warranty costs incurred on a product-by-product basis and compare the warranty costs to our estimated warranty obligation. With respect to new products, estimates are based generally on knowledge of the products and warranty experience, if a sufficient history exists.

Warranty reserves are established for costs that are expected to be incurred after the sale and delivery of products under warranty. Warranty reserves are included in accrued liabilities on our consolidated balance sheets. The warranty reserves are determined based on known product failures, historical experience and other available evidence. Warranty reserves were approximately $0.4 million as of November 28, 2020 and $0.5 million as of May 30, 2020.
