____________________ (1) Represents a pension settlement accounting loss incurred in conjunction with the freeze of our Company-sponsored qualified defined benefit pension plan in the United States (the "Qualified Plan") for non-union employees. Full year cash outflows are expected to exceed the service and interest cost components and trigger a settlement loss later in 2025 in the range of $6 million - $7 million. The first quarter loss was recorded based on this full year estimate.
