Net Gains

Net gains result from the sales of redundant properties (primarily land, buildings and related equipment) and non-core assets. In 2025, gains related to assets sold principally in HE primarily in North America. In 2024, gains related to assets sold principally in Corporate primarily in North America and HE primarily in Latin America. In 2023, gains related to assets sold in Rail primarily in Asia Pacific.

Employee Termination Benefit Costs

Costs and the related liabilities associated with involuntary termination benefit costs for one-time benefit arrangements provided as part of an exit or disposal activity are recognized when a formal plan for reorganization is approved at the appropriate level of management and is communicated to the affected employees. Additionally, costs associated with ongoing benefit arrangements, or in certain countries where statutory requirements dictate a minimum required benefit, are recognized when they are probable and estimable. The employee termination benefit cost in 2025 principally related to HE primarily in Western Europe and North America; and Rail primarily in North America. The employee termination benefit costs in 2024 principally related to HE primarily in Latin America and Western Europe; and Corporate primarily in North America. The employee termination benefit costs in 2023 principally related to HE primarily in Western Europe and CE in North America.

Other Costs to Exit Activities

Costs associated with exit or disposal activities include costs to terminate a contract and other costs associated with exit or disposal activities. Costs to terminate a contract are recognized when an entity terminates the contract or when an entity ceases using the right conveyed by the contract. This includes the costs to terminate the contract before the end of its term or the costs that will continue to be incurred under the contract for its remaining term without economic benefit to the entity. Other costs associated with exit or disposal activities (e.g., costs to sell a business, costs to consolidate or close facilities and relocate equipment or employees) are recognized and measured at their fair value in the period in which the liability is incurred. Also included are any benefits received in relation to an exit activity, such as a contract termination fee received from a customer. In 2025, exit costs were incurred principally in Corporate related to the planned sale of Clean Earth. In 2025 exit costs were also incurred in HE, mostly in Western Europe. In 2024, exit costs were incurred in HE, mostly in Latin America. In 2023, exit income was incurred principally in HE, mostly due to an $8.1 million net gain in North America related to a lease modification that resulted in a lease incentive for the Company to relocate a site prior to the end of the expected lease term. In 2023 exit costs were incurred related to the Rail sale efforts.

Asset Impairments

Asset impairments include impairment charges for long-lived assets, other than definite-lived intangibles, and are measured as the amount by which the carrying amount of assets exceeds their fair value. Fair value is estimated based upon the expected future realizable discounted cash flows including anticipated selling prices. Non-cash impaired asset write-downs, for long-lived assets other than definite-lived intangibles, are included in Other, net, on the Consolidated Statements of Cash Flows as adjustments to reconcile net income (loss) to net cash provided by operating activities. In all years presented, impaired asset write-downs were incurred primarily in HE across several regions. In 2025, Rail had an impaired asset write-down in Western Europe. In 2024, Rail had an impaired asset write-down in North America.

Contingent Consideration Adjustments

The Company acquired Clean Earth in 2019. Included in liabilities acquired was a contingent liability resulting from a prior Clean Earth acquisition. Each quarter, until settlement of the related contingencies, the Company assesses the likelihood that the acquired businesses will achieve performance goals and the resulting fair value of the contingent consideration and any future adjustments (increases or decreases) are included in operating results. In 2023, the Company recorded an adjustment related to expected reimbursement of net operating losses that did not occur which was the final settlement of Clean Earth contingencies.
