Compensation Actually Paid vs. Total Shareholder Return [Text Block]

Compensation actually paid (CAP) and Company total shareholder return (TSR)

The graph below illustrates the relationship between the CAP to our CEO and the other NEOs and the Company’s TSR during the period covered under the “Pay versus performance disclosure” above. The CAP figures shown below are calculated as required by SEC requirements, which include unvested and unpaid amounts. Each year of Company TSR reflects what the cumulative value of $100 would be, including reinvestment of dividends, if such amount were invested on June 1, 2020. As shown in the “Pay versus performance disclosure” above and below in the Company TSR vs. Peer Group TSR graph, the value of $100 invested in the Peer Group on June 1, 2020 would be $158.75 at the end of Fiscal 2021, $143.61 at the end of Fiscal 2022, $158.83 at the end of Fiscal 2023, and $227.62 at the end of Fiscal 2024.

Adjusted diluted earnings per share from continuing operations

Non-GAAP Measure Description [Text Block]

⁶ Adjusted diluted earnings per share from continuing operations, a non-GAAP financial measure, is our GAAP diluted earnings per share from continuing operations adjusted to exclude items of an unusual nature including but not limited to acquisition costs including integration and intangible amortization expenses, business divestitures, workforce actions, subsidies and costs, impairment and exit charges, facility consolidation and repositioning costs, investigation and remediation compliance costs, purchase accounting and legal settlements, strategic project costs, equity investments gains and losses, pension settlements, and significant customer events such as early terminations, contract restructurings, forward loss provisions and bankruptcies. We use this non-GAAP financial measure in our compensation structure as it illustrates our core operating performance unaffected by the impact of certain items that management does not believe are indicative of our ongoing and core operating activities.
