We were not required to and therefore did not contribute to our U.S. pension plans during the three and six months ended April 30, 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 Polish operations, at April 30, 2018 and October 31, 2017, we had a pension obligation liability of $1,261 and $1,008, respectively, based on actuarial reports. The Polish operations recognized $54 and $111 of expense for the three and six months ended April 30, 2018 and $39 and $77 for the three and six months ended April 30, 2017, respectively. For our Asian and other European operations, contributions are made to government sponsored programs or private pension funds. No unfunded liability exists for these operations.

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 statements of income 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 income separately from the service cost component and outside a subtotal of operating income. Therefore, $54 and $57 of service costs are included in cost of sales and $284 and $306 of net periodic pension and other post-retirement costs are included in other expense, net in the condensed consolidated statements of income for the three months ended April 30, 2018 and 2017, respectively, and $111 and $113 of service costs are included in cost of sales and $569 and $628 of net periodic pension and other post-retirement costs are included in other expense, net in the condensed consolidated statements of income for the six months ended April 30, 2018 and 2017, respectively. Prior year amounts have been reclassified to conform to the current year presentation in our condensed consolidated financial statements.
