Note 10—Benefit Plans and Other Postretirement Benefits

The Company and certain of its domestic subsidiaries have defined benefit pension plans (the “U.S. Pension Plans”), which cover certain U.S. employees and which represent the majority of the plan assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Pension Plans’ benefits are generally based on years of service and compensation and are generally noncontributory. The majority of U.S. employees are not covered by the U.S. Pension Plans and are instead covered by various defined contribution plans. The Company also has an unfunded Supplemental Employee Retirement Plan (“SERP” and, together with the U.S. Pension Plans, “U.S. Plans”), which provides for the payment of the portion of annual pension that cannot be paid from the retirement plan as a result of regulatory limitations on average compensation for purposes of the benefit computation. Certain foreign subsidiaries have defined benefit plans covering their employees (the “Foreign Plans” and, together with the U.S. Plans, the “Plans”).

The following is a summary, based on the most recent actuarial valuations, of the components of the Company’s net pension expense of the Company’s defined benefit plans for the three and six months ended June 30, 2025 and 2024:

	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024

Amortization of net actuarial losses		0.7		0.7		1.5		1.7
Net pension expense	$	1.0	$	0.6	$	2.1	$	1.8

There is no current requirement for cash contributions to any of the U.S. Plans, and the Company plans to evaluate annually, based on actuarial calculations and the investment performance of the Plans’ assets, the timing and amount of cash contributions in the future, if any.

The Company offers various defined contribution plans for certain U.S. and foreign employees. Participation in these plans is based on certain eligibility requirements. The Company matches employee contributions to the U.S. defined contribution plans up to a maximum of 7% of eligible compensation. During the six months ended June 30, 2025 and 2024, the Company provided matching contributions to the U.S. defined contribution plans of approximately $18.9 and $13.1, respectively.
