Income Taxes

(4) Income Taxes

We file income tax returns in the United States federal jurisdiction, all states, and various local and foreign jurisdictions. We are no longer subject to income tax examinations by taxing authorities for taxable years before 2019 in the case of United States federal examinations, and with limited exception, before 2017 in the case of foreign, state, and local examinations. During the first six months of 2023, there were no material changes in unrecognized tax benefits.
