Restructuring and Related Activities [Abstract]
Impairment and Restructuring Charge	Impairment and Restructuring Charges Long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The methods used to estimate fair value include the market approach (Level 2) and discounted cash flows (Level 3). The Company gives the greatest weight to the discounted cash flow method. The material estimates and assumptions used in the discounted cash flows method of determining fair value include: projected revenues, material costs and the rates of increase in payroll and other expenses. Projected future cash flows are discounted at a risk-free rate of return adjusted for various risk premiums. The Company conducted its periodic assessment of long-lived assets in the fourth quarter of fiscal 2012 and identified the need for an impairment charge in two of its reporting units that serve the solar equipment market that is included in the Company's Solar and Semiconductor Segment. The assessment identified the need to record an impairment charge related to goodwill in the amount of $4.7 million, due primarily to the supply / demand imbalance in the solar equipment market, the expectation that the market downturn would continue into 2013 and the decline in market value of shares of solar companies. The Company also recorded charges of $0.7 million in fiscal 2012 for impairment of assets related to license agreements with one of its technology partners. As a result of our technology partner's financial difficulties, their possible inability to service the product and insufficient revenues, management determined that the carrying value of the related assets was not recoverable. The Company conducted its periodic assessment of long-lived assets in the fourth quarter of fiscal 2013 and determined there was no impairment. The Company recorded restructuring charges of $0.9 million in fiscal 2013 primarily related to severance costs incurred as a result of the reductions-in-force at certain operations. The Company conducted its periodic assessment of long-lived assets in the fourth quarter of fiscal 2014 and determined there was no impairment.
