Employer Contributions

We make contributions to our pension plans to the extent that the contributions are tax deductible and pays benefits that relate to plans for salaried employees that cannot be funded under Internal Revenue Service regulations. We made employer contributions of $3 million to our pension plans and did not make any contributions to our postretirement plans during the three months ended March 31, 2022. Currently, we anticipate making additional employer contributions to our pension and postretirement plans of up to approximately $30 million for each plan in 2022. However, the foregoing estimates of 2022 contributions to our pension and postretirement plans are subject to change as a result of changes in tax and other benefit laws, changes in interest rates, as well as asset performance significantly above or below the assumed long-term rate of return for each respective plan
