Retirement Benefits [Abstract] |
Pension and Postretirement Benefits | Note 18. Pension and Postretirement Benefits Domestic Plans We have frozen defined benefit pension plans held in trust for certain employees which we funded. We also maintain certain unfunded defined benefit pension plans, which provide supplemental benefits to select management employees. These plans use traditional defined benefit formulas based on years of service and final average compensation. Funding policies provide that payments to defined benefit pension trusts shall be at least equal to the minimum funding required by applicable regulations. We also have certain defined benefit postretirement plans that provide medical and life insurance for certain eligible employees, retirees, and dependents. The related postretirement benefit liabilities are recognized over the period that services are provided by employees. In addition, we retained the obligations for these benefits for retirees of certain sold businesses. While the plans have no funding requirements, we may fund the plans. The components of net periodic benefit cost and other amounts of our pension plans recognized in other comprehensive income (loss) consist of the following:

We employ a total return investment approach whereby a mix of equities and fixed income securities is used to maximize the long-term return of plan assets for a prudent level of risk. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and corporate financial condition. The investment portfolio contains a diversified blend of equity and fixed income securities. Furthermore, equity securities are diversified across United States and non-United States stocks, as well as growth and value. Investment risk is measured and monitored on an ongoing basis through quarterly investment portfolio reviews and annual liability measurements. We utilize a building-block approach in determining the long-term expected rate of return on plan assets. Historical markets are studied and long-term historical relationships between equity securities and fixed income securities are preserved consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors such as inflation and interest rates are evaluated before long-term capital market assumptions are determined. The long-term portfolio return also considers diversification and rebalancing. Peer data and historical returns are reviewed relative to our assumed rates for reasonableness and appropriateness. The following pension and postretirement benefit payments, which reflect expected future service, as appropriate, are expected to be paid:

Foreign Pension Plans Certain of our foreign operations also maintain defined benefit pension plans held in trust for certain employees which are funded by the companies, and unfunded defined benefit pension plans providing supplemental benefits to select management employees. These plans use traditional defined benefit formulas based on years of service and final average compensation. Funding policies provide that payments to defined benefit pension trusts shall be at least equal to the minimum funding required by applicable regulations.

Multi-employer Plans We contribute to various defined benefit pension plans under the terms of collective bargaining agreements that cover our union-represented employees. The financial risks of participating in these multi-employer pension plans generally include the fact that the unfunded obligations of the plan may be borne by solvent participating employers. In addition, if we were to discontinue participating in some of our multi-employer pension plans, we could be required to pay a withdrawal liability amount based on the underfunded status of the plan. Currently, we do not anticipate triggering any withdrawal from any multi-employer pension plan to which we currently contribute. We also contribute to defined contribution plans pursuant to collective bargaining agreements, which are generally not subject to the funding risks inherent in defined benefit pension plans. The overall level of contributions to our multi-employer plans may significantly vary from year to year based on the demand for union-represented labor to support our operations. We do not have any minimum contribution requirements for future periods pursuant to our collective bargaining agreements for individually significant multi-employer plans. Our participation in multi-employer pension plans for 2022 is outlined in the following table. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2022 and 2021 relates to the plan’s year end as of December 31, 2021 and 2020, respectively, and is based on information received from the plan. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded, and plans in the green zone are at least 80% funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan or a rehabilitation plan is either pending or has been implemented.

Other Employee Benefits We match United States employee contributions to the 401(k) Plan with shares of our common stock held in treasury up to 100% of the first 3% of a participant’s salary plus 50% of the next 2%. The expense associated with our match was $3.5 million for 2022, $2.2 million for 2021, and $1.7 million for 2020. In April 2020, we suspended our 401(k) Plan employer match contributions, which were later reinstated in October 2020.
