Retirement Benefits [Abstract] |
PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS | PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS Our Company sponsors a qualified pension plan covering substantially all U.S. employees as well as unfunded nonqualified pension plans covering certain U.S. employees. Our Company also sponsors postretirement health care and life insurance benefit plans covering certain U.S. employees. In addition, our Company and its subsidiaries have various pension plans and other forms of postretirement benefit arrangements outside the United States. As of December 31, 2023, the U.S. qualified pension plan represented 63% and 56% of the Company’s consolidated projected benefit obligation and pension plan assets, respectively. Obligations and Funded Status The following table sets forth the changes in the benefit obligations and the fair value of plan assets for our pension and other postretirement benefit plans (in millions):

1 For pension plans, the benefit obligation is the projected benefit obligation. For other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation. The accumulated benefit obligation for our pension plans was $6,463 million and $6,307 million as of December 31, 2023 and 2022, respectively. 2 A change in the weighted-average discount rate assumption was the primary driver of net actuarial loss (gain) during 2023 and 2022. For our U.S. qualified pension plan, a decrease in the discount rate resulted in an actuarial loss of $129 million during 2023, and an increase in the discount rate resulted in an actuarial gain of $1,231 million during 2022. Additional drivers of net actuarial loss (gain) included other assumption updates and plan experience. 3 Settlements primarily related to the U.S. qualified pension plan, which was amended in 2023 to provide lump sum payment options to all former employees. The U.S. qualified pension plan made $259 million of lump sum payments in 2023, causing a plan settlement, which resulted in recognition of a $76 million settlement charge related to the acceleration of existing unrecognized losses. 4 In 2023, the Company settled its U.S. post-65 other postretirement benefit obligations such that retiree reimbursement accounts will be funded by an insurance company beginning January 1, 2025 for the lifetime of certain retirees and their eligible dependents. The transaction resulted in no change to underlying benefits or plan administration, but only to the future financing of the benefits. Pursuant to the settlement, the Company transferred $187 million of plan assets and liabilities to an insurer and recognized a $14 million net settlement credit related to the acceleration of existing unrecognized gains. Pension and other postretirement benefit plan amounts recognized in our consolidated balance sheets were as follows (in millions):

1 Mutual, pooled and commingled funds include investments in equity securities, fixed-income securities and combinations of both. There are a significant number of mutual, pooled and commingled funds from which investors can choose. The selection of the type of fund is dictated by the specific investment objectives and needs of a given plan. These objectives and needs vary greatly between plans. 2 Fair value disclosures related to our pension plan assets are included in Note 17. Fair value disclosures include, but are not limited to, the levels within the fair value hierarchy in which the fair value measurements in their entirety fall; a reconciliation of the beginning and ending balances of Level 3 assets; and information about the valuation techniques and inputs used to measure the fair value of our pension plan assets. Investment Strategy for U.S. Pension Plan The Company utilizes the s ervices of investment managers to actively manage the assets of our U.S. qualified pension plan. We have established asset allocation targets and investment guidelines with each investment manager. Our asset allocation targets promote optimal expected return and volatility characteristics given the long-term time horizon for fulfilling the obligations of the plan. Selection of the targeted asset allocation for U.S. pension plan assets is based upon a review of the expected return and risk characteristics of each asset class, as well as the correlation of returns among asset classes. Our target allocation is a mix of 18% equity securities, 47% fixed-income securities and 35% alternative investments. We believe this target allocation will enable us to achieve the following long-term investment objectives: (1)optimize the long-term return on plan assets at an acceptable level of risk; (2)maintain a broad diversification across asset classes and among investment managers; and (3)maintain careful control of the risk level within each asset class. The investment guidelines that have been established with each investment manager provide parameters within which the investment managers agree to operate, including criteria that determine eligible and ineligible securities, diversification requirements and credit quality standards, where applicable. Investment managers agree to obtain written approval for deviations from stated investment style or guidelines. As of December 31, 2023, no investment manager was responsible for more than 28% of total U.S. pension plan assets. Our target allocation of 18% equity securities is composed of 81% global equities, 11% emerging market equities and 8% domestic small-cap and mid-cap equities. Optimal returns through our investments in global equities are achieved through security selection as well as country and sector diversification. As of December 31, 2023, investments in our common stock accounted for 9% of total global equities and 5% of total U.S. pension plan assets. Our investments in global equities are intended to provide diversified exposure to both U.S. and non-U.S. equity markets. Our investments in both emerging market equities and domestic small-cap and mid-cap equities may experience large swings in their market value. Our investments in these asset classes are selected based on capital appreciation potential. Our target allocation of 47% fixed-income securities is composed of 62% long-duration bonds and 38% with multi-strategy alternative credit managers. Long-duration bonds are intended to provide a stable rate of return through investments in high-quality publicly traded debt securities. Our investments in long-duration bonds are diversified in order to mitigate duration and credit exposure. Multi-strategy alternative credit managers invest in a combination of high-yield bonds, bank loans, structured credit and emerging market debt. These investments are in lower-rated and non-rated debt securities, which generally produce higher returns compared to long-duration bonds and also help diversify our overall fixed-income portfolio. Our target allocation for alternative investments is 35%. These alternative investments include hedge funds, reinsurance, private equity limited partnerships, leveraged buyout funds, international venture capital partnerships and real estate. The objective of investing in alternative investments is to provide a higher rate of return than that which is typically available from publicly traded equity securities. Alternative investments are inherently illiquid and require a long-term perspective in evaluating investment performance. Investment Strategy for Non-U.S. Pension Plans The long-term target allocation for 66% of our international subsidiaries’ pension plan assets, primarily certain of our European and Canadian plans, is 60% equity securities, 29% fixed-income securities and 11% other investments. The actual allocation for the remaining 34% of the Company’s international subsidiaries’ pension plan assets consisted of 40% mutual, pooled and commingled funds; 23% fixed-income securities; 2% equity securities; and 35% other investments as of December 31, 2023. The investment strategies for our international subsidiaries’ pension plans vary greatly, and in some instances are influenced by local law. None of our pension plans outside the United States is individually significant for separate disclosure. Other Postretirement Benefit Plan Assets Plan assets associated with other postretirement benefits primarily represent funding of one of the U.S. postretirement health care benefit plans through a Voluntary Employee Beneficiary Association (“VEBA”), a tax-qualified trust. The VEBA assets are primarily invested in liquid assets due to the level and timing of expected future benefit payments.

1 The Company has elected to use the actual fair value of plan assets as the market-related value of plan assets in the determination of the expected return on plan assets. 2 Actuarial gains and losses are amortized using a corridor approach. The gain/loss corridor is equal to 10% of the greater of the benefit obligation and the market-related value of assets. Gains and losses in excess of the corridor are generally amortized over the average future working lifetime of the plan participants. 3 Settlements primarily related to the U.S. qualified pension plan, which was amended in 2023 to provide lump sum payment options to all former employees. The U.S. qualified pension plan made $259 million of lump sum payments in 2023, causing a plan settlement, which resulted in recognition of a $76 million settlement charge related to the acceleration of existing unrecognized losses. 4 Settlement charges were primarily related to our strategic realignment initiatives. Refer to Note 19. 5 In 2023, the Company settled its U.S. post-65 other postretirement benefit obligations such that retiree reimbursement accounts will be funded by an insurance company beginning January 1, 2025 for the lifetime of certain retirees and their eligible dependents. The transaction resulted in no change to underlying benefits or plan administration, but only to the future financing of the benefits. Pursuant to the settlement, the Company transferred $187 million of plan assets and liabilities to an insurer and recognized a $14 million net settlement credit related to the acceleration of existing unrecognized gains. All of the amounts in the table above, other than service cost, were recorded in the line item other income (loss) — net in our consolidated statements of income.

Assumptions Certain weighted-average assumptions used in computing the benefit obligations for our pension and other postretirement benefit plans were as follows:
| Pension Plans |  | Other Postretirement Benefit Plans
December 31, | 2023 | 2022 |  | 2023 | 2022
Discount rate | 5.00 | % | 5.50 | % |  | 6.25 | % | 6.00 | %
Interest crediting rate | 3.75 | % | 4.00 | % |  | N/A | N/A
Rate of increase in compensation levels | 4.00 | % | 3.75 | % |  | N/A | N/A
Certain weighted-average assumptions used in computing net periodic benefit cost or income were as follows:
| Pension Plans |  | Other Postretirement Benefit Plans
Year Ended December 31, | 2023 | 2022 | 2021 |  | 2023 | 2022 | 2021
Discount rate | 5.50 | % | 3.00 | % | 2.50 | % |  | 6.00 | % | 3.25 | % | 2.75 | %
Interest crediting rate | 4.00 | % | 3.00 | % | 3.00 | % |  | N/A | N/A | N/A
Rate of increase in compensation levels | 3.75 | % | 3.75 | % | 3.75 | % |  | N/A | N/A | N/A
Expected long-term rate of return on plan assets | 6.75 | % | 7.00 | % | 7.25 | % |  | 3.75 | % | 4.00 | % | 4.25 | %
The discount rate assumption used to account for pension and other postretirement benefit plans reflects the rate at which the benefit obligations could be effectively settled. The discount rate for U.S. and certain non-U.S. plans is determined using a matching technique whereby the rates of a yield curve, developed from high-quality debt securities, are applied to projected benefit cash flows to determine the appropriate effective discount rate. For other non-U.S. plans, we base the discount rate assumption on comparable indices within each of the countries. The Company measures the service cost and interest cost components of net periodic benefit cost or income for pension and other postretirement benefit plans by applying the specific spot rates along the yield curve to the plans’ projected benefit cash flows. The rate of compensation increase assumption is determined by the Company based upon annual reviews. The cash balance interest crediting rate for the U.S. qualified pension plan is based on the yield on six-month U.S. Treasury bills on the last day of September of the previous plan year, plus 150 basis points, with a minimum interest crediting rate of 3.80% for all active employees and certain former employees. The Company assumes that the ultimate interest crediting rate is 140 basis points lower than the plan’s year-end discount rate and that the current interest crediting rate will converge with the ultimate interest crediting rate after a period of 10 years. The expected long-term rate of return assumption for U.S. pension plan assets is based upon the target asset allocation and is determined using forward-looking assumptions in the context of historical returns and volatilities for each asset class, as well as correlations among asset classes. We evaluate the expected long-term rate of return assumption on an annual basis. The expected long-term rate of return assumption used in computing 2023 net periodic benefit income for the U.S. pension plans was 6.75%. As of December 31, 2023, the 5-year, 10-year and 15-year annualized return for the U.S. pension plan assets was 6.7%, 6.1% and 8.3%, respectively. The annualized return since inception was 9.9%. The weighted-average assumptions for health care cost trend rates were as follows:
December 31, | 2023 | 2022
Health care cost trend rate assumed for next year | 8.50 | % | 8.25 | %
Rate to which the trend rate is assumed to decline (the ultimate trend rate) | 6.00 | % | 5.50 | %
Year that the trend rate reaches the ultimate trend rate | 2029 | 2030
We review external data and our own historical trends for health care costs to determine the health care cost trend rate assumptions. The Company’s U.S. postretirement health care benefits are primarily provided through plans with either a capped Company cost or a defined-dollar benefit. This limits the effects of health care inflation on the Company. Cash Flows The expected benefit payments for our pension and other postretirement benefit plans for the 10 years succeeding December 31, 2023 are as follows (in millions):
| 2024 | 2025 | 2026 | 2027 | 2028 | 2029-2033
Benefit payments for pension plans | $ | 654 |  | $ | 615 |  | $ | 611 |  | $ | 614 |  | $ | 489 |  | $ | 2,421 |
Benefit payments for other postretirement benefit plans | 49 |  | 29 |  | 27 |  | 24 |  | 23 |  | 99 |
Total | $ | 703 |  | $ | 644 |  | $ | 638 |  | $ | 638 |  | $ | 512 |  | $ | 2,520 |
The Company anticipates making contributions of approximately $47 million to our pension trusts in 2024, all of which will be allocated to our international plans. These contributions are made in accordance with local laws and tax regulations. Defined Contribution Plans Our Company sponsors qualified defined contribution plans covering substantially all U.S. employees. Under the largest U.S. defined contribution plan, we match participants’ contributions up to a maximum of 3.0% to 3.5% of compensation, subject to an IRS limit on compensation. The Company’s expense for the U.S. plans totaled $44 million, $45 million and $32 million in 2023, 2022 and 2021, respectively. We also sponsor defined contribution plans in certain locations outside the United States. The Company’s expense for these plans totaled $82 million in 2023 and $79 million in both 2022 and 2021. Multi-Employer Retirement Plans The Company participates in various multi-employer retirement plans, which are designed to provide benefits to, or on behalf of, employees of multiple employers. These plans are typically established under collective bargaining agreements. Multi-employer retirement plans are generally governed by a board of trustees composed of representatives of both management and labor and are generally funded through employer contributions. The Company’s expense for multi-employer retirement plans totaled $1 million in 2023, 2022 and 2021. The plans we currently participate in have contractual arrangements that extend into 2026. If, in the future, we choose to withdraw from any of the multi-employer retirement plans in which we currently participate, we would record the appropriate withdrawal liability, if any, at that time
