Financial Instruments And Concentration Of Credit Risk [Abstract]
Financial Instruments And Concentration Of Credit Risk [Text Block]	Note 11—Financial Instruments and Concentration of Credit Risk The carrying amounts of cash equivalents, accounts receivable, accrued liabilities, accounts payable and capital lease obligations approximate fair value. As of December 31, 2013, the Company's investments are recorded at fair value. See Note 1(e). As of December 31, 2013, the Company had no significant off-balance sheet concentrations of credit risk such as foreign currency exchange contracts or other hedging arrangements. Financial instruments that subject the Company to credit risk consist of cash and cash equivalents, investments and trade accounts receivable. Management maintains the majority of the Company's cash and cash equivalents with financial institutions. One of the most significant credit risks is the ultimate realization of accounts receivable. This risk is mitigated by (i) sales to well established companies, (ii) ongoing credit evaluation of customers, and (iii) frequent contact with customers, thus enabling management to monitor current changes in business operations and to respond accordingly. Management considers these concentrations of credit risks in establishing our allowance for doubtful accounts and believes these allowances are adequate. The Company's largest customer represented approximately 22% and 23% of its gross accounts receivable as of December 31, 2013 and 2012, respectively.
