Investments, All Other Investments [Abstract]
Investment	INVESTMENT In the third quarter of 2009, we made a strategic investment of $5.0 million in Solicore, Inc., headquartered in Lakeland, Florida. Solicore is focused on penetrating the market for embedded power solutions, offering its patented Flexicon advanced ultra-thin, flexible, lithium polymer batteries for smart cards, controlled access cards, RFID tags, and medical devices. Our investment, part of a total of $13.3 million raised by Solicore in that financing round, provided us with a minority equity stake in Solicore and representation on Solicore's Board of Directors. We account for this investment under the cost method as we cannot exert significant influence over the business. We also entered into a joint development agreement with Solicore to develop the next generation of power solution products using screen printing technology. If this technology is adopted, we will have the option to manufacture a significant portion of the products that result from this collaboration. In the first quarter of 2013, we made an additional investment of $0.1 million in Solicore. During the fourth quarter of 2013, Solicore raised additional equity capital through a round of capital financing that decreased our ownership interest in Solicore as we did not participate in this round of financing. Further, the financing round was issued at a significantly lower price than when we had initially invested in Solicore. In accordance with the applicable accounting guidance, this event represented an indicator of impairment. As a result, we performed an impairment test during the fourth quarter of 2013. The valuation was based on an option pricing methodology to estimate the per share value of the equity classes of stock held in Solicore. This method utilized a Black-Scholes option pricing model and the analytic process utilized to perform the valuation, which included back solving for the total equity value of Solicore. Based on the results of this valuation, there was a significant decline in the fair value of the Solicore business, which caused us to recognize an impairment charge on our investment in Solicore of approximately $4.6 million. The remaining book value of our investment in Solicore is approximately $0.5 million.
