| Non-GAAP Measure Description [Text Block] | In accordance with SEC rules, the Company is required to include in the Pay versus Performance table the “most important” financial performance measure (as determined by the Company) used to link compensation actually paid to our named executive officers to Company performance for the most recently completed fiscal year. The Company determined Adjusted Net Earnings which is a metric included in our long-term incentive program, meets this requirement and therefore, we have included this financial performance measure in the Pay versus Performance table. For fiscal years 2022 and 2021, a reconciliation of Adjusted Net Earnings to the nearest GAAP measure can be found in our Form 10-K filed with the SEC on March 1, 2023 and for fiscal year 2020, a reconciliation of Adjusted Net Earnings to the nearest GAAP measure can be found in our Form 10-K filed with the SEC on March 4, 2022. | | |
