Warranty expense rate description			Our warranty expense rate in the three months ended October 1, 2022 is a result of a decrease in the use of higher-cost contract labor we had used in the first half of 2022 to respond to warranty claims due to a currently tight labor market.During the nine months ended October 1, 2022, we recorded warranty expense at a rate of approximately 2.0% of sales, which was slightly lower than the rate during the nine months ended October 2, 2021 of 2.1% of sales. Our warranty expense rate in the nine months ended October 1, 2022 was affected by the use of higher-cost contract labor during the first quarter of 2022 to respond to warranty claims in a currently tight labor market. The rate in the nine months ended October 2, 2021 includes the effect of wind-down of certain commercial business in the first quarter of 2021, which resulted in warranty costs higher than those we would incur in the normal course of business.
