​ 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 federal income tax purposes. It is too early to determine, but we do not anticipate that we will be required to fund a minimum required contribution under ERISA. Regardless, it is possible that we may fund the qualified and nonqualified pension plans in 2021 for a combined total of up to $125.0 million. During the three and nine months ended September 30, 2021, we contributed $20.7 million and $92.1 million to these plans, respectively. Other Postretirement Plan Changes Effective January 1, 2021, $656.5 million of assets in excess of the expected liability to cover the postretirement medical benefits for retirees were re-designated for non-retiree benefits. The elections were made pursuant to plan provisions, which provide for assets in excess of 125% of expected liabilities to fund other benefits covered under the plans. The re-designated assets, net of associated tax receivable impacts related to a tax adjustment to accumulated other comprehensive income, are not included as part of the asset balances presented in the footnote as they no longer qualify as plan assets in accordance with U.S. GAAP. The re-designated assets are included in equity securities and other investments on our consolidated statements of financial position beginning January 1, 2021. Change in Plan Assets The other postretirement benefits plans’ change in plan assets, reconciled to amounts recognized in the consolidated statements of financial position, was as follows: ​
