Loss per Share
Loss per Share	5. Loss per Share Basic net loss per common share has been calculated based upon the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is also computed using the weighted average number of common shares and excludes dilutive potential common shares outstanding, as their effect is anti-dilutive. Dilutive potential common shares consist primarily of employee stock options and stock warrants. Diluted net loss per share is equal to basic net loss per share and is therefore not presented separately in the financial statements. The weighted average number of potential common shares that would have been included in diluted loss per share, had their effect not been anti-dilutive for each of the three-month and nine-month periods ended September 30, 2013, were approximately 4,000 shares and 141,000 shares, respectively, versus 342,000 shares and 814,000 shares for the three-month and nine-month periods ended September 30, 2012, respectively. Employee stock options and other stock warrants to purchase a weighted average of approximately 5,983,000 and 5,486,000 shares were outstanding for the three-month and nine-month periods ended September 30, 2013, respectively, versus 2,625,000 and 1,981,000 shares for the three-month and nine-month periods ended September 30, 2012, respectively, but have not been included in the computation of diluted loss per share because their exercise price was greater than the average share price of Wave’s common shares and, therefore, their effect would have been anti-dilutive.
