The Company retrospectively adopted ASU 2017-07 - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost on June 3, 2018. As the Company's pension and post retirement medical plans are frozen and not open to new plan participants, these plans no longer have a service component in net periodic benefit cost. Prior to adoption, the Company recorded net periodic benefit costs related to its defined benefit pension and post-retirement medical plans within Selling, general and administrative expenses. As a result of adoption, these costs are recorded within Other, net. The Company retrospectively reclassified $0.4 million and $0.8 million of net periodic benefit cost in the Condensed Consolidated Statements of Comprehensive Income for the three and six month periods ended December 2, 2017, respectively, from Selling, general and administrative to Other, net. The Company made a voluntary contribution of $12.0 million to its International defined benefit pension plan in the six month period ended December 2, 2017.
