[1] | We adopted ASU 2017-07 on January 1, 2018, which requires retrospective adoption. As a result, we recorded the nonservice cost component of net periodic benefit cost within other expense for the three and nine months ended September 30, 2018, and we reclassified $0.2 million from operating expenses to other expense for the three months ended September 30, 2017 and $0.9 million for the nine months ended September 30, 2017 to conform with current period presentation. Refer to Note 1 – Overview and Basis of Presentation for additional details on the impact of this adoption on our Condensed Consolidated Statements of Operations.
