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.

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.
