Loss per Share	4. 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 quarters ended March 31, 2013 and 2012, were approximately 1,791,930 shares and 3,969,000 shares, respectively. Employee stock options and other stock warrants to purchase a weighted average of approximately 18,594,000 and 16,852,000 shares were outstanding for the quarters ended March 31, 2013 and 2012 respectively, but these shares were not included in the computation of diluted loss per share because the exercise price of these stock options and other stock warrants was greater than the average share price of Wave’s common shares and, therefore, their effect would have been anti-dilutive.
