Restructuring and Other Related Costs Disclosure | RESTRUCTURING AND OTHER RELATED COSTS Summary of Restructuring Plans. In fiscal year 2025, we announced a restructuring plan designed to optimize our management structure to better serve our customers. In fiscal years 2024 and 2023, we announced restructuring plans that were both designed to reduce costs and expenses in response to macroeconomic conditions. These actions impact all three of our operating segments. The costs associated with these restructuring plans were not allocated to our operating segments' results; however, each operating segment will benefit from the future cost savings from these actions. When completed, the restructuring programs are expected to result in the reduction in annual cost of sales and operating expenses over the three operating segments. A summary of our aggregate liability related to the restructuring plans and the total restructuring expense since inception of those plans are shown in the table below:
