The Corporation’s effective tax rate was comparable in the three months ended September 30, 2023 and October 1, 2022. The effective tax rate was higher in the nine-month period ended September 30, 2023 compared to October 1, 2022, primarily due to non-deductible transaction costs in the current year related to the acquisition of Kimball International, as well as tax benefits
recognized in the prior-year period for valuation adjustments related to existing deferred tax assets and basis differences tied to the sale of Lamex in July 2022.
