During 2020, the Company announced it was freezing its United States pension plans for its non-union employees. The freeze was effective January 1, 2021 for non-union U.S. employees whose retirement benefit was determined under a cash balance formula and was effective January 1, 2026 for non-union U.S. employees whose retirement benefit is determined under a final average pay formula.
Actuarial losses related to changes in the United States and Non-United States benefit obligations in 2025 of $55 million and $13 million, respectively, were primarily due to decreases in the discount rates used to measure the obligations as well as unfavorable plan experience. Actuarial gains related to changes in the United States and Non-United States benefit obligations in 2024 of $20 million and $82 million, respectively, were primarily due to increases in the discount rates used to measure the obligations.

Retirement Benefits Plans Assumptions
In 2025, 2024 and 2023, for purposes of determining liabilities related to the majority of its plans in the United States, the Company used the Pri-2012 mortality tables as well as mortality tables that are based on the Company's own experience and generational improvement scales that are based on MP-2021.
To estimate the service and interest cost components of net periodic benefit cost for the vast majority of its defined benefits pension and other postretirement benefits plans, the Company used a spot rate approach by applying the specific spot rates along the yield curve used to measure the benefit obligation at the beginning of the period to the relevant projected cash flows.

The expected long-term rate of return on pension assets was determined for each country and reflects long-term historical data taking into account each plan's target asset allocation. The expected long-term rates of return on pension assets for United States pension plans and Non-United States pension plans for 2026 are 7.50% and 7.00%, respectively. The discount rates were determined using appropriate bond data for each country.
Other Postretirement Benefits Plans
Substantially all of the obligation for other postretirement benefits plans relates to United States plans. Assumptions used to determine other postretirement benefits obligations and expense are as follows:

Pension Plan Assets
Investment policies and strategies are developed on a country and plan specific basis. The United States plan, representing 59% of worldwide pension assets, and the United Kingdom plans representing 26% of worldwide pension assets, are invested primarily in debt securities largely for liability hedging, as the majority of the assets are in plans that are well-funded. In general, the plans are primarily allocated to diversified high-quality publicly traded debt, primarily through separately managed accounts and commingled funds in the form of common collective and other trusts. The United States plan's target allocation is 21% United States equities, 11% non-United States equities, 4% public real estate (primarily equity of real estate investment trusts), 46% debt securities and 18% other, including private equity, private debt and cash equivalents. The United Kingdom plans' target asset allocations are 16% equities and the remainder in debt securities, cash equivalents and real estate investments. The equity risk for the plans is managed through broad diversification across industries, geographies, and levels of market capitalization. The majority of debt allocations for these plans are longer duration government and corporate debt. The United States, United Kingdom and Canada pension plans are authorized to use derivatives, including the use of futures, swaps and options, to achieve more economically desired market exposures.
Fair Value Measurements
Financial instruments included in pension and other postretirement benefits plan assets are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology are as follows:
Level 1 -Quoted prices (unadjusted) for identical assets in active markets.
Level 2 -Quoted prices for similar assets in active markets, and inputs that are observable for the asset, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3 -Unobservable prices or inputs.
Certain investments that are measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables to permit a reconciliation to total plan assets.

Valuation Methodologies
Following is a description of the valuation methodologies used for pension and other postretirement benefits plan assets measured at fair value. There have been no changes in the methodologies used at December 31, 2025 and 2024.
Common collective and other trusts - Valued at the net unit value of units held by the trust at year end. The unit value is determined by the total value of fund assets divided by the total number of units of the fund owned. The equity investments in collective trusts are predominantly in index funds for which the underlying securities are actively traded in public markets based upon readily measurable prices. The investments in other trusts are predominantly in exchange traded funds for which the underlying securities are actively traded in public markets based upon readily measurable prices. Common collective and other trusts measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets.
Fixed income securities - These securities consist of publicly traded United States and non-United States fixed interest obligations (principally corporate and government bonds and debentures). The fair value of corporate and government debt securities is determined through third-party pricing models that consider various assumptions, including time value, yield curves, credit ratings, and current market prices. The Company verifies the results of trustees or custodians and evaluates the pricing classification of these securities by performing analyses using other third-party sources.
United States treasuries - Valued at the closing price of each security.
Real estate - Consists of direct investments in the stock of publicly traded companies and investments in pooled funds that invest directly in real estate. The publicly traded companies are valued based on the closing price reported in an active market on which the individual securities are traded and as such are classified as Level 1. The pooled funds rely on appraisal-based valuations and as such are classified as Level 3.
Cash equivalents - Primarily certificates of deposit, commercial paper, and repurchase agreements.
Exchange traded funds - Valued at the closing price of the exchange traded fund's shares.
Money market funds - Money market funds measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy and are being presented in the tables above to permit a reconciliation of the fair value hierarchy to the total plan assets.
Other - These assets consist of private equity, private debt, insurance contracts primarily for international plans, futures contracts, and over-the-counter options. Investments in private equity and private debt are valued at net asset value or estimated fair value based on quarterly financial information received from the investment advisor, third party appraisal or general partner. These estimates incorporate factors such as contributions and distributions, market transactions, market comparables and performance multiples. Futures contracts and options are valued based on the closing prices of contracts or indices as available using third-party sources.
For additional information regarding fair value measurements, see Note 15.
Defined Contribution Plans
The Company has various defined contribution benefit plans, primarily consisting of the plans in the United States. The total contributions related to these plans are charged to expense and are as follows:
