Goodwill Disclosure [Text Block]	(4) Goodwill Goodwill is tested for impairment annually as of December 31 or more frequently if impairment indicators arise. If impairment indicators arise, a step one assessment is performed to identify any possible goodwill impairment in the period in which the indicator is identified. The December 31, 2012 review of goodwill indicated that goodwill was not impaired. Beginning in March 2013, we noted certain indicators relating to our Electronics Group reporting unit that were significant enough to conclude that an impairment indicator existed as of March 31, 2013. Specifically, one key customer within the Electronics Group’s space business communicated its strategic sourcing decision to begin insourcing programs that had been previously outsourced to the Electronics Group. Overall, the Electronics Group has been more impacted by declines in the overall government defense market than originally anticipated as the effects of sequestration have become clearer since its initial effective date on March 1, 2013. For example, sales of certain data recording products were significantly reduced due to the impact of sequestration on our customers, and the loss of commercial space business was due in part to our customer’s efforts to offset unrelated losses of government business due to sequestration. As a result, the Electronics Group’s short term revenue forecasts were materially affected. For purposes of the interim goodwill impairment analysis, the Company assesses recoverability using a discounted cash flow analysis. The analysis is based upon available information regarding expected future cash flows for each reporting unit, discounted at rates consistent with the cost of capital specific to the reporting unit. A growth rate is used to calculate the terminal value of the reporting unit and is added to the present value of the forecasted cash flows. The growth rate is the expected rate at which a reporting unit’s cash flow is projected to grow beyond the period covered by the long-range plan. The sum of the calculated fair values of each reporting unit is then reconciled and compared to our total market capitalization, allowing for a reasonable control premium. If the discounted cash flow analysis yields a fair value estimate less than the reporting unit’s carrying value, we proceed to step two in considering whether goodwill may be impaired. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of the identified assets and liabilities of the reporting unit. As part of this process, the Company reviewed the recoverability of the Electronics Group’s short-term and long-term assets excluding goodwill and concluded that no impairment of these assets was necessary. The cash flow analysis, discount rate and terminal value all require significant judgment and significantly influence our evaluation of each reporting unit and its estimated fair value. In selecting these and other assumptions for each business, we consider historical performance, forecasted operating results, expected changes in product mix, general market conditions and industry considerations specific to the business. We make significant assumptions and estimates about the extent and timing of future cash flows, growth rates and discount rates. The cash flows are estimated over a future period of time, which makes those estimates and assumptions inherently subject to a high degree of uncertainty. Key assumptions used to determine the fair value of the Electronics Group included the expected after-tax cash flows for the period from 2013 to 2017 and a terminal growth rate of 3.0%, which is consistent with historical expectations. Our analysis also included a comparison of our market capitalization to the estimated fair value for the entire enterprise. Significant assumptions utilized during the valuation process are impacted by economic conditions and expectations of management and may change in the future based on period-specific facts and circumstances. The first step of the impairment test indicated that the estimated fair value for the Electronics Group was less than its carrying value as of March 31, 2013. We performed step two of the impairment test and determined that the implied goodwill for the reporting unit was lower than its value as of March 31, 2013. As a result, a non-cash impairment charge of $6,900,000 was recorded during the three months ended March 31, 2013 to impair the goodwill associated with the Electronics Group reporting unit. The impairment charge has been presented separately in the consolidated statements of operations and fully impairs the carrying amount of goodwill related to the Electronics Group. The fair value of the Electronics Group and the assets and liabilities identified in the step two impairment test were determined using the combination of the income approach and the market approach, which are Level 3 and Level 2 inputs, respectively.

(4) Goodwill

Goodwill is tested for impairment annually as of December 31 or more frequently if impairment indicators arise. If impairment indicators arise, a step one assessment is performed to identify any possible goodwill impairment in the period in which the indicator is identified.
