Measure Name | Cash Earnings |  |
Non-GAAP Measure Description [Text Block] | We determined cash earnings to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2022. More information about cash earnings can be found in the annual bonus section of the Compensation Discussion and Analysis beginning on page 53. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years. |  |
