2019 Annuity Contract Buy-out

On October 8, 2019, we purchased a single premium group annuity contract from an insurance company to provide for the payment of pension benefits to 2,634 primary U.S. pension plan participants. We purchased the contract with $53 million of plan assets. The insurance company will take over the payments of these benefits starting January 1, 2020, at which date the beneficiaries will cease to be participants in the primary U.S. pension plan and the plan will have no further obligation to these participants. This transaction settles $54 million of our primary U.S. pension plan obligation. As a result, we expect to recognize a settlement charge of approximately $20 million in the fourth quarter of 2019. The actual amount of the charge will depend upon various actuarial assumptions, including discount rate, at the remeasurement date. After the settlement, there are expected to be approximately 11,400 beneficiaries remaining in the primary U.S. pension plan.
