Federal returns currently under examination | The Company is currently under state audit and remains subject to income tax examinations in the U.S. and various state and foreign jurisdictions for tax years 2017-2020. During 2022, the Company resolved several U.S. and foreign examinations, including limited transfer pricing disputes that existed for years dating back to 2008. The Company believes it has adequately reserved for income taxes that could result from any audit adjustments. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. |  |  |  |
