We have not recorded any uncertain tax positions during 2020 and 2021 and have no unrecognized tax benefits at December 31, 2020 and December 31, 2021. We recognize interest accrued and penalties related to unrecognized tax benefits in income taxes. The statute of limitations related to the consolidated federal income tax return is closed for all years prior to 2018.
