Subsequent Events [Abstract]
Subsequent Event	11. SUBSEQUENT EVENT On April 30, 2015, Firerock Global Opportunity Fund LP filed a complaint in the Northern District of Illinois asserting federal securities claims against the Company, certain officers, its directors and the underwriters in the Company’s March 2014 stock offering (the “Complaint”). The Complaint seeks as a remedy either money damages or rescission of the March offering, plus attorneys’ fees. The Company intends to vigorously defend this lawsuit. Due to the preliminary nature of the lawsuit, at this time, we cannot predict an outcome, nor is it reasonably possible to estimate the amount or range of loss, if any, that would be associated with an adverse decision.
