Gain Contingency, Description		On January 26, 2010, the Company commenced an action against Taiwan Glass Industrial Corp. ("Taiwan Glass") in the United States District Court for the Southern District of New York. By that action, the Company seeks monetary damages ($5,816,000) against Taiwan Glass for breach of contract.
Loss Contingency, Damages Sought	The Company believes that Taiwan Glass has no legal basis for unilaterally refusing to accept and pay for equipment specially manufactured for them and shipped to them by the Company. Taiwan Glass has interposed an answer and counterclaims denying these allegations and is seeking unspecified monetary damages. On April 12, 2012, Taiwan Glass filed a Motion seeking Partial Summary Judgment in the amount of $3,564,000 (representing the portion of the purchase price that it had previously paid to the Company). By Memorandum and Order dated November 7, 2012, the Court denied the Taiwan Glass Motion in its entirety. The Company is vigorously pursuing its claims against Taiwan Glass.
