In the first quarter of 2022, the Company recognized a non-cash settlement charge of approximately $1 million. Settlements from a certain U.S. pension plan exceeded the plan’s service and interest cost. This triggered settlement accounting which required the immediate recognition of a portion of the accumulated losses associated with the plan.

Contributions

Assuming no additional contributions are agreed to with, or required by, the pension plan trustees, the Company expects to make total cash contributions of approximately $7 million, $52 million, and $15 million, (at December 31, 2021 exchange rates) to its significant U.K., U.S., and other major pension plans, respectively, during 2022. The following table summarizes contributions made to the Company’s significant pension plans (in millions):
