Atmus Plans

Atmus has defined benefit pension plans, which provide retirement benefits to eligible participants and are collectively referred to as the “Atmus Plans.” The plans’ benefits are primarily based on employee earnings and credited service.

Plans in two countries, Belgium and Mexico, were newly established in 2023.

The total Atmus Plans’ defined benefit pension plan expenses were $1.7 million in 2024, $0.9 million in 2023 and $2.0 million in 2022. Service costs allocated to Atmus were $1.3 million in 2024, $0.6 million in 2023 and $1.5 million in 2022. These costs are reflected in the Consolidated Financial Statements as a component of Cost of sales, Research, development and engineering expenses and Selling, general and administrative expenses. The non-service costs allocated to Atmus were immaterial for each of the years ended December 31, 2024, 2023 and 2022. These non-service costs are reflected in the Consolidated Financial Statements as a component of Other income, net.

The aggregate status of all over funded plans is recognized as an asset and the aggregate status of all underfunded plans is recognized as a liability in the Consolidated Balance Sheets. The liabilities were $11.0 million and $9.6 million as of December 31, 2024 and 2023, respectively, and are reflected in the Consolidated Financial Statements as a component of Other liabilities. The current portion of the liabilities were immaterial as of December 31, 2024 and 2023. The amounts recognized as assets were $2.1 million and $0 million as of December 31, 2024 and 2023, respectively, and are reflected in the Consolidated Financial Statements as a component of Other assets.
