Retirement Benefits [Abstract] |
Employee Benefit Plans | NOTE K - EMPLOYEE BENEFIT PLANS Restructuring and plan remeasurement During the first quarter of fiscal 2025, as part of its fiscal 2024 restructuring activities, Ashland terminated approximately 40 employees in its Doel, Belgium facility. The post-retirement benefits for these employees, all of whom participated in a non-contributory defined benefit plan in Belgium, were frozen. This resulted in a decrease in total expected future years of service within the plan and required Ashland to remeasure the plan as of December 31, 2024. As a result, Ashland recorded a $1 million curtailment loss within the other net periodic benefit loss caption of the Statement of Condensed Consolidated Comprehensive Income (Loss) for the six months ended March 31, 2025. Plan contributions For the six months ended March 31, 2025, Ashland contributed $4 million to its U.S. pension plans and $3 million to its non-U.S. pension plans. Ashland expects to make additional contributions of $2 million to its U.S. pension plans and $2 million to its non-U.S. pension plans during the remainder of fiscal 2025. Components of net periodic benefit costs The following table details the components of pension and other postretirement benefit costs for continuing operations.
