Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract] |
Schedule of Net Periodic Benefit Cost | During March 2017, the Financial Accounting Standards Board issued Accounting Standards Update No. 2017-07 (“ASU 2017-07”). This amendment to GAAP will require us to exclude the components of net periodic benefit cost other than service cost from operating income on October 1, 2018, with early adoption permitted. We plan to adopt this amendment on October 1, 2017, and this adoption will require reclassification of 2017 and 2016 results. The components of net periodic benefit cost for our pension plans and the effects this adoption will have on operating income are presented below.
