8. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

The Company has entered into agreements for electricity and to purchase equipment and components to construct furnaces. These agreements will result in the Company purchasing electricity, equipment or components for a total cost of approximately $2.0 million with deliveries occurring through December 2016.

Litigation

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, the Company 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.
