We record the service component of net periodic cost as part of "Cost of sales" and "Selling, general, and administrative expenses," while the non-service component of net periodic cost is recorded in "Other non-operating expense" on our Consolidated Statements of Operations. For the quarter and six months ended June 30, 2026, we recorded $0.6 million and $1.2 million to "Cost of sales" and $0.1 million and $0.2 million to "Selling, general, and administrative expenses." For the quarter and six months ended June 30, 2025, we recorded $0.7 million and $1.3 million to "Cost of sales" and $0.1 million and $0.3 million to "Selling, general, and administrative expenses."

During the quarter ended June 30, 2026, we contributed $0.5 million to our qualified pension plans, which is included in the "defined benefit pension and other postretirement employee benefits" line on the statement of cash flows. We expect to contribute an additional $2.9 million to fund our pension benefit plans in 2026.
