- Definition

Restructuring costs refer to one-time expenses that a company incurs when reorganizing its operations to improve long-term profitability. These costs can include employee layoffs, closing facilities, relocating assets, and other significant changes. Reversals of restructuring costs occur when previously recognized restructuring expenses are no longer expected to be incurred, often due to changes in the company's plans.
