Deferred Compensation Arrangement with Individual, Share-based Payments [Line Items]
Deferred Compensation Arrangement with Individual, Description	On September 22, 2009, the Company entered into an employment agreement (the “Agreement”) with Dr. Keh-Shew Lu, President and Chief Executive Officer of the Company (the “Employee”), pursuant to which he will continue to be employed by the Company in such positions for an additional six-year term. As part of the Agreement, the Company and the Employee entered into a Stock Award Agreement that provides that: (i) the Company shall grant to the Employee 100,000 shares of Common Stock in the form of restricted stock awards on each of April 14, 2010, 2011, 2012, 2013, 2014 and 2015; (ii) each such installment would vest only if the Company achieved a specified amount of net sales; (iii) upon the termination of the Employee’s employment, the Company’s obligation to grant any subsequent installment would terminate; and (iv) any granted shares would be automatically forfeited and returned to the Company if the Employee’s employment with the Company is terminated before the Company achieves the specified target amount of net sales, except in the case of death or disability (as defined) in which case the granted shares would become fully vested on the date of death or disability. The estimated fair value of this grant is approximately $12 million and is being expensed on a straight line basis through April 14, 2015. As of December 31, 2012, no installments have vested. As of December 31, 2012, three annual installments have been granted and are included in the above table as granted but not vested.
