[1] For the U.S. pension plans, the benefit obligation is both the PBO and ABO as these plans are frozen and future benefit accruals no longer increase with future compensation increases. For the international pension plans, the benefit obligation is the PBO. The ABO for our international pension plans was $6.8 billion in 2025 and $7.1 billion in 2024. For the postretirement plans, the benefit obligation is the ABO.
[2] For 2025, primarily includes actuarial gains resulting from increases in discount rates for the international pension plans, partially offset by actuarial losses resulting from decreases in discount rates for the U.S. pension and postretirement plans. For 2024, primarily includes actuarial losses resulting from decreases in discount rates for the international pension plans, and other assumption changes for the postretirement plans, largely offset by actuarial gains resulting from increases in discount rates for the U.S. pension plans.
[3] Our U.S. qualified plans, U.S. postretirement plan and many of our larger funded international plans were overfunded as of December 31, 2025.
