We were not required and therefore did not contribute to our U.S. pension plans during the three and nine months ended July 31, 2017 and as required, made one contribution of $950 to pension plans during the nine months ended July 31, 2016. No further contributions for the remainder of fiscal 2017 are required.

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, the pension obligations for the fiscal year ended 2017 are expected to be $1,070 based on actuarial reports. The Polish operations recognized $42 and $119 of expense for the three and nine months ended July 31, 2017 and $26 and $78 for the three and nine months ended July 31, 2016, respectively.
