​ The components of net periodic benefit cost including the service cost component are included in operating expenses on the consolidated statements of operations. Contributions Our funding policy for our qualified pension plan is to fund the plan annually in an amount at least equal to the minimum annual contribution required under the Employee Retirement Income Security Act (“ERISA”) and, generally, not greater than the maximum amount that can be deducted for U.S. federal income tax purposes. We do not anticipate contributions will be needed to satisfy the minimum funding requirements of ERISA for our qualified plan in 2025; however, it is possible that we may fund both the qualified and nonqualified pension plans in 2025 for a combined total of up to $70.0 million. During the three months ended March 31, 2025, we did not contribute to these plans.
