The Polish operations recognized $52 and $42 of expense for the three months ended July 31, 2018 and 2017, respectively, and $163 and $119 for the nine months ended July 31, 2018 and 2017, respectively. For our Asian, other European and Mexican 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, $52 and $41 of service costs are included in cost of sales and $284 and $327 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 July 31, 2018 and 2017, respectively, and $163 and $154 of service costs are included in cost of sales and $853 and $955 of net periodic pension and other post-retirement costs are included in other expense, net in the condensed consolidated statements of operations for the nine months ended July 31, 2018 and 2017, respectively. Prior year amounts have been reclassified to conform to the current year presentation in our condensed consolidated financial statements.
