The components of the net periodic benefit cost for defined benefit and other post-retirement plans are as follows:

As discussed in Note 17, effective January 1, 2018, the Company adopted the new guidance that changes the presentation of net periodic pension cost and net periodic postretirement cost (''net periodic benefit costs"). The new guidance requires employers to report the service cost component of net periodic benefit costs in the same line item as other compensation costs in the income statement. The other components of net periodic benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. The new guidance requires retrospective application for the presentation of the service cost component and the other components of net periodic benefit costs. Accordingly, we have reclassified prior period information in the following chart to conform with the current year's presentation:
