Curtailments and Settlements of Employee Benefit Plans

In December 2018, the Company transferred the majority of the defined benefit obligations and pension plan assets in one of its foreign defined benefit plans to a multi-employer plan. This action moved the administrative, asset custodial, asset investment, actuarial, communication and benefit payment obligations to the multi-employer fund administrator. As a result of the transfer, there was a $30 million reduction in net pension obligations associated with the plan, and a pre-tax gain of $6 million was recorded in the first quarter of fiscal 2019, which is included in Other income (expense) in the Consolidated Statement of Operations. The pre-tax gain consisted of a curtailment credit of less than $1 million for the accelerated recognition of prior service credit and a settlement credit of $5 million for the accelerated recognition of the unrecognized gain upon the transfer of the assets. As of March 31, 2019, approximately $2 million of plan assets remain to be transferred. Such assets are expected to be transferred by the end of the third quarter of fiscal 2019 and such transfer may result in an additional immaterial settlement gain or loss. In addition, as part of the transfer the Company recorded a $3 million charge in the first quarter of fiscal 2019 for the Company’s agreement to fund the actuarial loss gap between the terminated plan and the multi-employer plan, which will be paid over the next five years. This charge is included Other income (expense) in the Consolidated Statement of Operations and the liability is included in Accounts payable and accrued liabilities and Other liabilities on the Consolidated Balance Sheet.
