Investments in and Advances to Affiliates, Schedule of Investments [Text Block]	6. Investment in Unconsolidated Affiliate Investments in unconsolidated entities over which the company has significant influence over the investees’ operating and financing activities are accounted for under the equity method of accounting. Investments in affiliates in which the company does not have such ability are accounted for under the cost method of accounting. In April 2012, the company invested an additional $10.0 million in certain common and preferred stock of Shocking Technologies, Inc. (“Shocking”) increasing its previous investment interest in Shocking to $16.0 million or approximately 18.4%. In addition, in late-November 2012, the company provided an additional $2.0 million short-term secured loan to Shocking and determined that the company then had the ability to exert significant influence. As a result, the company began accounting for the investment in Shocking using the equity method. In accordance with ASC 323, the company retroactively recorded its proportional share of Shocking's operating losses, which amounted to approximately $4.0 million in 2012. Impairment During the first quarter of 2013, the company fully impaired its investment in a loan receivable from Shocking owing to their filing for Chapter 7 bankruptcy on March 12, 2013. The impairment charge of approximately $10.7 million consisted of the remaining equity method investment of $8.7 million and a $2.0 million loan receivable, and reduced the carrying value of both the investment and loan receivable to zero at March 30, 2013. During the fourth quarter of 2013, the company incurred a $6.1 million charge to income tax expense related to the company’s investment in Shocking which had been fully impaired and written off as described above. $3.3 million of this charge was pushed back to the first quarter of 2013 with the remaining $2.8 million (which related to the fourth quarter of 2012) recorded in the fourth quarter of 2013 as the correction of an immaterial error under ASC 250. This charge was determined to be a capital loss for tax purposes, instead of an ordinary loss as the company had previously determined in consultation with a third party expert.
