Defined benefit plan, estimated future employer contributions in current fiscal year, description We have a contributory defined benefit plan that covers certain employees in the United Kingdom. As of September 30, 2022, the underfunded liability for this defined benefit plan was approximately $3.9 million. We have agreed to a schedule of contributions of GBP 2.0 million (approximately $2.4 million based on a GBP: USD exchange rate of 1.2:1) to be paid in annual installments that began on March 31, 2021, and payments to be made by December 31 each year thereafter).
