In 2018, the Company terminated and settled its frozen U.S. defined benefit pension plan, the Waters Retirement Plan, by making lump-sum cash payments and purchasing annuity contracts for participants to permanently extinguish the pension plan’s obligations. The Company also anticipates that it will settle the Waters Retirement Restoration Plan during 2019, and the Company may incur pension accounting charges in connection with the termination of this plan.

During fiscal year 2019, the Company expects to contribute a total of approximately $3 million to $6 million to the Company’s defined benefit plans.
