Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Change in Accounting Method During the fourth quarter of fiscal year 2023, the Company changed its accounting method related to the recognition of actuarial gains and losses for the Company’s pension and postretirement benefit plans (the “Accounting change”). Prior to the Accounting change, actuarial gains and losses were recognized as a component of Accumulated other comprehensive income (loss) upon annual remeasurement and were amortized into earnings in future periods when they exceeded the accounting corridor, a defined range within which amortization of net gains and losses is not required. Under the Accounting change, the accounting corridor of 10% of the greater of the projected benefit obligation and plan assets was modified to add full, immediate recognition above a second 20% threshold. Although the decision to make the Accounting change occurred in the fourth quarter of fiscal year 2023, the actual accounting method change was applied to all calculations for fiscal year end 2023, and retroactively applied to all other amounts presented in this Form 10-Q. Under the new accounting method, actuarial gains and losses are recognized in net periodic benefit cost through a modified mark-to-market (expense) benefit upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events warrant remeasurement. The method for recognizing prior service credits (charges) as a component of Accumulated other comprehensive income (loss) and amortized into earnings in future periods did not change. With respect to the recognition of actuarial gains and losses, while the historical principle was acceptable, the Company believes the Accounting change is preferable as it better aligns with fair value principles by recognizing the effects of economic and interest rate changes in plan assets and liabilities in the year in which the gains and losses are incurred to the degree such accumulated gains and losses exceed the new 20% threshold in addition to amortizing the amounts between the 10% and 20% thresholds over time. The Accounting change has been applied retrospectively to prior years and amounts presented.

Change in Accounting Method

During the fourth quarter of fiscal year 2023, the Company changed its accounting method related to the recognition of actuarial gains and losses for the Company’s pension and postretirement benefit plans (the “Accounting change”). Prior to the Accounting change, actuarial gains and losses were recognized as a component of Accumulated other comprehensive income (loss) upon annual remeasurement and were amortized into earnings in future periods when they exceeded the accounting corridor, a defined range within which amortization of net gains and losses is not required. Under the Accounting change, the accounting corridor of 10% of the greater of the projected benefit obligation and plan assets was modified to add full, immediate recognition above a second 20% threshold. Although the decision to make the Accounting change occurred in the fourth quarter of fiscal year 2023, the actual accounting method change was applied to all calculations for fiscal year end 2023, and retroactively applied to all other amounts presented in this Form 10-Q.

Under the new accounting method, actuarial gains and losses are recognized in net periodic benefit cost through a modified mark-to-market (expense) benefit upon annual remeasurement in the fourth quarter, or on an interim basis as triggering events warrant remeasurement. The method for recognizing prior service credits (charges) as a component of Accumulated other comprehensive income (loss) and amortized into earnings in future periods did not change. With respect to the recognition of actuarial gains and losses, while the historical principle was acceptable, the Company believes the Accounting change is preferable as it better aligns with fair value principles by recognizing the effects of economic and interest rate changes in plan assets and liabilities in the year in which the gains and losses are incurred to the degree such accumulated gains and losses exceed the new 20% threshold in addition to amortizing the amounts between the 10% and 20% thresholds over time. The Accounting change has been applied retrospectively to prior years and amounts presented.
