Retirement Benefits [Abstract] |
Pension and Postretirement Benefits | PENSION AND POSTRETIREMENT BENEFITS We sponsor several noncontributory defined benefit pension plans, covering substantially all U.S. employees and certain non-U.S. employees, which provide benefits based on years of service, age, job grade levels and type of compensation. Retirement benefits for all other covered employees are provided through contributory pension plans, cash balance pension plans and government-sponsored retirement programs. All funded defined benefit pension plans receive funding based on independent actuarial valuations to provide for current service and an amount sufficient to amortize unfunded prior service over periods not to exceed 30 years, with funding falling within the legal limits prescribed by prevailing regulation. We also maintain unfunded defined benefit plans that, as permitted by local regulations, receive funding only when benefits become due. Our defined benefit plan strategy is to ensure that current and future benefit obligations are adequately funded in a cost-effective manner. Additionally, our investing objective is to achieve the highest level of investment performance that is compatible with our risk tolerance and prudent investment practices. Because of the long-term nature of our defined benefit plan liabilities, our funding strategy is based on a long-term perspective for formulating and implementing investment policies and evaluating their investment performance. The asset allocation of our defined benefit plans reflects our decision about the proportion of the investment in equity and fixed income securities, and, where appropriate, the various sub-asset classes of each. At least annually, we complete a comprehensive review of our asset allocation policy and the underlying assumptions, which includes our long-term capital markets rate of return assumptions and our risk tolerances relative to our defined benefit plan liabilities. The expected rates of return on defined benefit plan assets are derived from review of the asset allocation strategy, expected long-term performance of asset classes, risks and other factors adjusted for our specific investment strategy. These rates are impacted by changes in general market conditions, but because they are long-term in nature, short-term market changes do not significantly impact the rates. Our U.S. defined benefit plan assets consist of a portfolio of equity and fixed income securities. Our non-U.S. defined benefit plan assets include a significant concentration of United Kingdom fixed income securities. We monitor investment allocations and manage plan assets to maintain acceptable levels of risk. For all periods presented, we used a measurement date of December 31 for each of our U.S. pension plans, non-U.S. pension plans and postretirement medical plans. U.S. Defined Benefit Plans We maintain qualified and non-qualified defined benefit pension plans in the U.S. The qualified plan provides coverage for substantially all full-time U.S. employees who receive benefits, up to an earnings threshold specified by the U.S. Department of Labor. The non-qualified plans primarily cover a small number of employees including current and former members of senior management, providing them with benefit levels equivalent to other participants, but that are otherwise limited by U.S. Department of Labor rules. The U.S. plans are designed to operate as "cash balance" arrangements, under which the employee has the option to take a lump sum payment at the end of their service. The difference between total accumulated benefit obligation and total projected benefit obligation ("Benefit Obligation") is immaterial. In August 2023, we amended the Company-sponsored qualified defined benefit pension plan in the United States (the "Qualified Plan") for non-union employees to discontinue future benefit accruals under the Qualified Plan and freeze existing accrued benefits effective January 1, 2025. Benefits earned by participants under the Qualified Plan prior to January 1, 2025, are not affected. We also amended the Company-sponsored non-qualified defined benefit pension plan in the United States (the "Non-Qualified Plan") that provides enhanced retirement benefits to select members of management. The Qualified Plan and the Non-Qualified plan were closed to new entrants effective January 1, 2024, and September 1, 2023, respectively. The amendments resulted in a curtailment of both plans during the year ended December 31, 2023. The curtailment loss incurred and the change in projected benefit obligation was immaterial. In conjunction with the amendment of the Qualified Plan, the Organization and Compensation Committee of our Board of Directors approved certain transition benefits associated with freezing the Qualified Plan. In January 2025, a one-time cash transition benefit was paid to a limited group of employees in the United States that met certain criteria. We recorded a $5.0 million liability for the period ended December 31, 2024, which is included within accrued liabilities in our consolidated balance sheet to recognize this obligation, with corresponding expense included within COS and SG&A in our consolidated statements of income. We also issued approximately the same amount of value in the form of restricted shares to an additional group of employees in the United States in January 2025. The restricted shares are subject to three year cliff-vesting. The following are assumptions related to the U.S. defined benefit pension plans:
| Year Ended December 31,
| 2024 |  | 2023 |  | 2022
Weighted average assumptions used to determine Benefit Obligations: |  |  |  |  |
Discount rate | 5.73 | % |  | 5.41 | % |  | 5.73 | %
Rate of increase in compensation levels | 4.00 |  |  | 4.00 |  |  | 3.50 |
Weighted average assumptions used to determine net pension expense: |  |  |  |  |
Long-term rate of return on assets | 6.00 | % |  | 6.00 | % |  | 5.75 | %
Discount rate | 5.41 |  |  | 5.73 |  |  | 3.00 |
Rate of increase in compensation levels | 4.00 |  |  | 3.50 |  |  | 3.50 |
Weighted-average interest crediting rates | 4.00 | % |  | 4.00 | % |  | 3.79 | %
At December 31, 2024 as compared with December 31, 2023, we increased our discount rate from 5.41% to 5.73% based on an analysis of publicly traded investment grade U.S. corporate bonds, which had a higher yield due to current market conditions. In determining 2024 expense, the expected rate of return on U.S. plan assets is 6.00%, primarily based on our target allocations and expected long-term asset returns. The long-term rate of return assumption is calculated using a quantitative approach that utilizes historical returns and asset allocation as inputs for the calculation. For all U.S. plans, we adopted the Pri-2012 mortality tables and the MP-2021 improvement scale published in October 2021. We applied the Pri-2012 tables based on the constituency of our plan population for union and non-union participants. We adjusted the improvement scale to utilize the Proxy SSA Long Term Improvement Rates, consistent with assumptions adopted by the Social Security Administration trustees, based on long-term historical experience. Currently, we believe this approach provides the best estimate of our future obligation. Most plan participants elect to receive plan benefits as a lump sum at the end of service, rather than an annuity. As such, the updated mortality tables had an immaterial effect on our pension obligation. Net pension expense for the U.S. defined benefit pension plans (including both qualified and non-qualified plans) was:

We contributed $20.7 million and $3.1 million to the U.S. defined benefit pension plans during 2024 and 2023, respectively. All U.S. defined benefit plan assets are held by the qualified plan. The asset allocations for the qualified plan at the end of 2024 and 2023 by asset category, are as follows:
| Target Allocation at December 31, |  | Percentage of Actual Plan Assets at December 31,
Asset category | 2024 |  | 2023 |  | 2024 |  | 2023
Cash and cash equivalents | 1 | % |  | 1 | % |  | 1 | % |  | 2 | %
Cash and cash equivalents | 1 | % |  | 1 | % |  | 1 | % |  | 2 | %

Fixed income | 57 | % |  | 65 | % |  | 56 | % |  | 62 | %
None of our common stock is directly held by our qualified plan. Our investment strategy is to earn a long-term rate of return consistent with an acceptable degree of risk and minimize our cash contributions over the life of the plan, while taking into account the liquidity needs of the plan. We preserve capital through diversified investments in high quality securities. Our current allocation target is to invest approximately 42% of plan assets in equity securities and 57% in fixed income securities. Within each investment category, assets are allocated to various investment strategies. Professional money management firms manage our assets, and we engage a consultant to assist in evaluating these activities. We periodically review the allocation target, generally in conjunction with an asset and liability study and in consideration of our future cash flow needs. We regularly rebalance the actual allocation to our target investment allocation. Plan assets are invested in commingled funds. Our "Pension and Investment Committee" is responsible for setting the investment strategy and the target asset allocation for the plan's assets. As the qualified plan approached fully funded status, we implemented a Liability-Driven Investing ("LDI") strategy, which more closely aligns the duration of the plan's assets with the duration of its liabilities. The LDI strategy results in an asset portfolio that more closely matches the behavior of the liability, thereby reducing the volatility of the plan's funded status. The plan’s financial instruments, shown below, are presented at fair value. See Note 1, "Significant Accounting Policies and Accounting Developments," for further discussion on how the hierarchical levels of the fair values of the Plan’s investments are determined. The fair values of our U.S. defined benefit plan assets were:
| At December 31, 2024 |  | At December 31, 2023

Non-U.S. Defined Benefit Plans We maintain defined benefit pension plans, which cover some or all of our employees in the following countries: Austria, Belgium, Canada, France, Germany, India, Italy, Japan, Mexico, Saudi Arabia, Qatar, UAE, The Netherlands, Switzerland and the United Kingdom. The assets of the plans in the United Kingdom (two plans), The Netherlands and Canada represent 87% of the total non-U.S. plan assets ("non-U.S. assets"). Details of other countries’ plan assets have not been provided due to immateriality. The following are assumptions related to the non-U.S. defined benefit pension plans:
| Year Ended December 31,
| 2024 |  | 2023 |  | 2022
Weighted average assumptions used to determine Benefit Obligations: |  |  |  |  |
Discount rate | 4.71 | % |  | 4.22 | % |  | 4.46 | %
Rate of increase in compensation levels | 3.51 |  |  | 3.24 |  |  | 3.61 |
Weighted average assumptions used to determine net pension expense: |  |  |  |  |
Long-term rate of return on assets | 4.65 | % |  | 3.97 | % |  | 2.43 | %
Discount rate | 4.22 |  |  | 4.46 |  |  | 1.71 |
Rate of increase in compensation levels | 3.24 |  |  | 3.62 |  |  | 3.18 |
Weighted-average interest crediting rates | 2.06 | % |  | 2.29 | % |  | 1.49 | %
At December 31, 2024, as compared with December 31, 2023, we increased our average discount rate for non-U.S. plans from 4.22% to 4.71% based on analysis of bonds and other publicly traded instruments, by country, which had higher yields due to market conditions. To determine 2024 pension expense, our average expected rate of return on plan assets increased to 4.65% based on our target allocations and expected long-term asset returns. As the expected rate of return on plan assets is long-term in nature, short-term market fluctuations do not significantly impact the rate. Many of our non-U.S. defined benefit plans are unfunded, as permitted by local regulation. The expected long-term rate of return on assets for funded plans was determined by assessing the rates of return for each asset class and is calculated using a quantitative approach that utilizes unadjusted historical returns and asset allocation as inputs for the calculation. We work with our actuaries to determine the reasonableness of our long-term rate of return assumptions by looking at several factors including historical returns, expected future returns, asset allocation, risks by asset class and other items.

In 2024, the U.K. and The Netherlands plans contributed to the decrease in plan assets. The U.K. and The Netherlands pension plans contributed to the change in the non-U.S. plan assets due to higher asset returns in 2023. Our contributions to non-U.S. defined benefit pension plans in 2025 are expected to be approximately $2 million, excluding direct benefits paid. The asset allocations for the non-U.S. defined benefit pension plans at the end of 2024 and 2023 are as follows:

None of our common stock is held directly by these plans. In all cases, our investment strategy for these plans is to earn a long-term rate of return consistent with an acceptable degree of risk and minimize our cash contributions over the life of the plan, while taking into account the liquidity needs of the plan and the legal requirements of the particular country. We preserve capital through diversified investments in high quality securities. Asset allocation differs by plan based upon the plan’s benefit obligation to participants, as well as the results of asset and liability studies that are conducted for each plan and in consideration of our future cash flow needs. Professional money management firms manage plan assets and we engage a consultant in the United Kingdom to assist in evaluation of these activities. The assets of the U.K. plans are overseen by a group of Trustees who review the investment strategy, asset allocation and fund selection. These assets are passively managed as they are invested in index funds that attempt to match the performance of the specified benchmark index. The fair values of the non-U.S. assets were:

_______________________________________ (a)U.K. Government Gilt Index represents U.K. government issued fixed income investments which are passively managed to track their respective benchmarks. (b)LDI seeks to invest in fixed income securities that collectively closely match those found in discount curves used to value the plan's liabilities. (c)Multi-asset seeks an attractive risk-adjusted return by investing in a diversified portfolio of strategies, including equities and fixed income. (d)The Buy-in Contracts ("Contract" or "Contracts") represent assets held by plans, whereby the cost of providing benefits to plan participants is funded by the Contract. The Contracts are held by the plans for the benefit of plan participants in the Netherlands and United Kingdom. The fair value of these assets are based on the current present value of accrued benefits and will fluctuate based on changes in the obligations associated with covered plan members as well as the assumptions used in the present value calculation. The fair value of assets held in the Netherlands Contract as of January 1, 2024 was $16.9 million, with benefit payments of $1.0 million, contributions and return on assets of $0.3 million and negative currency adjustments of $1.0 million resulting in a fair value of $15.2 million at December 31, 2024. Similarly, the fair value of asset held in the U.K. plan Contract as of January 1, 2024 was $14.8 million, with benefit payments of $1.0 million, return on assets of $1.9 million and negative currency adjustments of $0.3 million resulting in a fair value of $15.4 million at December 31, 2024. There were no material transfers into or out of Level III. (e)Includes assets held by plans outside the United Kingdom, the Netherlands and Canada. Details of each plan have not been provided due to immateriality. The fair value of the assets as of January 1, 2024 was $20.9 million, with contributions of $10.5 million, payments of $9.2 million, settlements and return on assets of $1.1 million and negative currency adjustments of $2.2 million resulting in a fair value of $21.1 million at December 31, 2024. There were no material transfers into or our of Level III. Defined Benefit Pension Plans with Accumulated Benefit Obligations in Excess of Plan Assets The following summarizes key pension plan information regarding U.S. and non-U.S. plans whose accumulated benefit obligations exceed the fair value of their respective plan assets.

Postretirement Medical Plans We sponsor several defined benefit postretirement medical plans covering certain current retirees and a limited number of future retirees in the United States. These plans provide for medical and dental benefits and are administered through insurance companies and health maintenance organizations. The plans include participant contributions, deductibles, co-insurance provisions and other limitations and are integrated with Medicare and other group plans. We fund the plans as benefits and health maintenance organization premiums are paid, such that the plans hold no assets in any period presented. Accordingly, we have no investment strategy or targeted allocations for plan assets. Benefits under our postretirement medical plans are not available to new employees or most existing employees. The following are assumptions related to postretirement benefits:
| Year Ended December 31,
| 2024 |  | 2023 |  | 2022
Weighted average assumptions used to determine Benefit Obligation: |  |  |  |  |
Discount rate | 5.78 | % |  | 5.57 | % |  | 5.83 | %
Weighted average assumptions used to determine net expense: |  |  |  |  |
Discount rate | 5.57 | % |  | 5.83 | % |  | 2.83 | %
The assumed ranges for the annual rates of increase in medical costs used to determine net expense were 7.00% for 2024, 7.00% for 2023 and 7.25% for 2022, with a gradual decrease to 5.00% for 2032 and future years. Net postretirement benefit cost for postretirement medical plans was:

We made contributions to the postretirement medical plans to pay benefits of $1.1 million in 2024, $1.6 million in 2023 and $2.4 million in 2022. Because the postretirement medical plans are unfunded, we make contributions as the covered individuals’ claims are approved for payment. Accordingly, contributions during any period are directly correlated to the benefits paid.
Defined Contribution Plans We sponsor several defined contribution plans covering substantially all U.S. and Canadian employees and certain other non-U.S. employees. Employees may contribute to these plans, and these contributions are matched in varying amounts by us, including discretionary matching contributions. Defined contribution plan expense was $29.8 million in 2024, $23.6 million in 2023 and $21.9 million in 2022.
