The decrease in periodic benefit costs for the three and six months ended March 31, 2017 as compared to the corresponding period last year was primarily due to the curtailment of our U.K. plans and the de-recognition of the U.S. pension plan for participating employees who were assigned to, and worked exclusively on, a specific operating contract with the U.S. federal government. While these costs were fully reimbursed by the U.S. federal government pursuant to applicable cost accounting standards, net periodic pension costs of $1.1 million are included in our net periodic benefit costs table for the period ended March 31, 2017.
