Warranty expense rate description	Our warranty expense rate in the three months ended April 2, 2022 is a result of an increase in the use of higher-cost contract labor to respond to warranty claims due to a currently tight labor market, whereas in the three months ended April 3, 2021, the wind-down of the commercial business of NewSouth in the first quarter of 2021 resulted in warranty costs higher than those we would incur in the normal course of business.
