Retirement Benefits [Abstract] |
Retirement Plans | 16 Retirement Plans U.S. employees are eligible to participate in the Waters Employee Investment Plan, a 401(k) defined contribution plan, immediately upon hire. Employees may contribute up to 60% of eligible pay on a pre-tax or post-tax basis and the Company makes matching contributions of 100% for contributions up to 6% of eligible pay. The Company also sponsors a 401(k) Restoration Plan, which is a nonqualified defined contribution plan. Employees are 100% vested in employee and Company matching contributions for both plans. For the years ended December 31, 2024, 2023 and 2022, the Company’s matching contributions amounted to $20 million, $22 million and $21 million, respectively. The Company also sponsors other employee benefit plans in the U.S., including a retiree healthcare plan, which provides reimbursement for medical expenses and is contributory. There are various employee benefit plans outside the United States (both defined benefit and defined contribution plans). Certain non-U.S. defined benefit plans (“Non-U.S. Pension Plans”) are included in the disclosures below, which are required under the accounting standards for retirement benefits. The Company contributed $18 million, $18 million and $16 million in the years ended December 31, 2024, 2023 and 2022, respectively, to the non-U.S. plans (primarily defined contribution plans) which are currently outside of the scope of the required disclosures. The eligibility and vesting of non-U.S. plans are consistent with local laws and regulations. The net periodic pension cost is made up of several components that reflect different aspects of the Company’s financial arrangements as well as the cost of benefits earned by employees. These components are determined using the projected unit credit actuarial cost method and are based on certain actuarial assumptions. The Company’s accounting policy is to reflect in the projected benefit obligation all benefit changes to which the Company is committed as of the current valuation date; use a market-related value of assets to determine pension expense; amortize increases in prior service costs on a straight-line basis over the expected future service of active participants as of the date such costs are first recognized; and amortize cumulative actuarial gains and losses in excess of 10% of the larger of the market-related value of plan assets and the projected benefit obligation over the expected future service of active participants. Summary data for the U.S. Retiree Healthcare Plan and Non-U.S. Pension Plans are presented in the following tables, using the measurement dates of December 31, 2024 and 2023, respectively. The reconciliation of the projected benefit obligations for the plans at December 31, 2024 and 2023 is as follows (in thousands):

The change in the Company’s projected benefit obligation for the year ended December 31, 2024 was primarily due to net actuarial gains that arose during the year driven by a n increase in discount rates, differences between expected and actual return on plan assets, and fluctuations in foreign currency exchange rates during the year. The change in the Company’s projected benefit obligation for the year ended December 31, 2023 was primarily due to net actuarial losses that arose during the year driven by a decrease in discount rates, differences between expected and actual return on plan assets, and fluctuations in foreign currency exchange rates during the year.

The asset allocation policy for the U.S. Retiree Healthcare Plan was developed in consideration of the following long-term investment objectives: achieving a return on assets consistent with the investment policy, achieving portfolio returns which compare favorably with those of other similar plans, professionally managed portfolios and of appropriate market indexes and maintaining sufficient liquidity to meet the obligations of the plan. Within the equity portfolio of the U.S. Retiree Healthcare Plan, investments are diversified among market capitalization and investment strategy, and targets a 45% allocation of the equity portfolio to be invested in financial markets outside of the United States. The Company does not invest in its own stock within the U.S. Retiree Healthcare Plan’s assets. Plan assets are measured at fair value using the following valuation techniques and inputs:
Level 1: |  | The fair value of these types of investments is based on market and observable sources from daily quoted prices on nationally recognized securities exchanges.
Level 2: |  | The fair value of these types of investments utilizes data points other than quoted prices in active markets that are observable either directly or indirectly.
Level 3: |  | These bank and insurance investment contracts are issued by well-known, highly-rated companies. The fair value disclosed represents the present value of future cash flows under the terms of the respective contracts. Significant assumptions used to determine the fair value of these contracts include the amount and timing of future cash flows and counterparty credit risk.
There have been no changes in the above valuation techniques associated with determining the value of the plans’ assets during the years ended December 31, 2024 and 2023. The fair value of the Company’s retirement plan assets are as follows at December 31, 2024 (in thousands):

To develop the expected long-term rate of return on assets assumption, the Company considered historical returns and future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio and historical expenses paid by the plan. A one-quarter percentage point increase in the assumed long-term rate of return on assets would decrease the Company’s net periodic benefit cost by less than $1 million. A one-quarter percentage point increase in the discount rate would decrease the Company’s net periodic benefit cost by less than $1 million. During fiscal year 2025, the Company expects to contribute a total of approximately $3 million to $6 million to the Company’s defined benefit plans. Estimated future benefit payments from the plans as of December 31, 2024 are as follows (in thousands):
