The components of net periodic benefit cost for the three months ended January 31, 2018 and 2017 are as follows:

We were not required to and therefore did not contribute to our U.S. pension plans during the three months ended January 31, 2018 and 2017. We expect to contribute at least $450 to our U.S. pension plans in fiscal 2018.

Non-U.S. Plans

For our Swedish operations, the majority of the pension obligations are covered by insurance policies with insurance companies. For our Polish operations, at January 31, 2018 and October 31, 2017, we had a pension obligation liability of $1,325 and $1,008, respectively, based on actuarial reports. The Polish operations recognized $57 and $38 of expense for the three months ended January 31, 2018 and 2017, respectively.

Early Adoption of ASU 2017-07 - Impact

In accordance with the Company's early adoption of ASU 2017-07, we report the service cost component of the net periodic pension and post-retirement costs in the same line item in the statement of operations as other compensation costs arising from services rendered by the employees during the period for both our U.S. and Non-U.S. Plans. The other components of net periodic pension and post-retirement costs are presented in the statement of operations separately from the service cost component

and outside a subtotal of operating income. Therefore, $57 and $56 of service costs are included in cost of sales and $285 and $322 of net periodic pension and other post-retirement costs are included in other expense, net in the condensed consolidated statements of operations for the three months ended January 31, 2018 and 2017, respectively. Prior year amounts have been reclassified to conform to the current year presentation in our condensed consolidated financial statements.
