Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average outstanding common shares during the period. Diluted earnings per share is calculated by dividing net income by the number of shares outstanding under the basic calculation and adding all dilutive securities, which consist of options. The Company incurred a net loss for the three months ended June 30, 2011 and six months ended June 30, 2011 and 2010. Accordingly, basic and diluted net loss per common share are the same for each period as the effect of stock options is anti-dilutive. Shares of underlying stock options not included in the diluted computation amounted to 1,228,200 at June 30, 2011 and 1,689,700 at June 30, 2010.
