Restructuring and Related Activities [Abstract]
Restructuring Costs	RESTRUCTURING COSTS On March 10, 2015 the Company announced and implemented a restructuring plan to further lower its cost structure. The cost reductions covered all divisions and included the corporate offices, but were weighted to Applied Technology as a result of the decline in this business and the expectation of continued end-market weakness for this division. This action was taken in addition to a preemptive restructuring of the Engineered Films Division in the fourth quarter of fiscal 2015 to address the expected decline in demand in the energy sector as the result of falling oil prices, as well as the Applied Technology restructuring announced in November 2014. The Company incurred restructuring costs for severance benefits of $588 in the nine-month period ended October 31, 2015. This restructuring plan was completed during fiscal 2016 second quarter so no costs were incurred related to this restructuring plan in the three-month period ended October 31, 2015 and there were no unpaid costs at October 31, 2015. The Company reported $407 of this expense in "Cost of sales" and the remaining $181 in "Selling, general, and administrative expenses" in the Consolidated Statements of Income and Comprehensive Income. Substantially all of these restructuring costs related to the Applied Technology Division. The Company incurred no restructuring costs in the three- or nine-month periods ended October 31, 2014. Subsequent to the end of fiscal 2015, the Company announced that Applied Technology's remaining contract manufacturing operations in the St. Louis, Missouri area had been successfully sold and transferred. The exit activities related to this sale and transfer were substantially completed during the first quarter. There were no impairments recorded as a result of the exit activity and gains of $611 were recorded in the nine-month period ended October 31, 2015. There were no gains recorded in the three-month period ended October 31, 2015. Receivables for inventory and estimated future royalties pursuant to the sale agreements were $420 and were reflected in "Other current assets" in the Consolidated Balance Sheet at October 31, 2015. Aerostar Division (Vista) Restructuring Plan In addition to the restructuring plan announced in first quarter, the Company's Aerostar segment implemented a restructuring plan at Vista in October 2015 due to reduced demand expectations primarily related to delays and uncertainty surrounding international pursuits. The lower cost structure will preserve the Company's capabilities to pursue domestic and international opportunities for Vista's radar products and technology. Vista incurred restructuring costs for severance benefits of $73 in the three- and nine-month periods ended October 31, 2015. The restructuring plan was implemented late in third quarter so virtually all of these costs were unpaid at October 31, 2015. The Company reported $58 of this expense in "Cost of sales" and the remaining $15 in "Research and development expenses" in the Consolidated Statements of Income and Comprehensive Income. In addition to these restructuring costs, Vista incurred a goodwill impairment loss, a long-lived asset impairment loss, and a write-off of some deferred pre-contract costs. These one-time charges are further described in Note 7 Goodwill and Long-lived Asset Impairment Loss and Other Charges. Vista incurred no restructuring costs in the three- or nine-month periods ended October 31, 2014.
