Net Loss Per Share

2. NET LOSS PER SHARE

Basic net loss per share is calculated using the weighted-average number of common shares outstanding during the reporting periods. Diluted net loss per share is calculated using the weighted-average number of common shares outstanding and taking into account the dilutive effect of all potentially dilutive securities, including common stock equivalents and convertible securities outstanding. Potentially dilutive common stock equivalents primarily consist of warrants, employee stock options and nonvested equity shares. Diluted net loss per share for the three and six months ended June 30, 2011 and 2010 is equal to basic net loss per share because the effect of all potential common stock outstanding during the periods, including options, warrants and nonvested equity shares is anti-dilutive. The components of basic and diluted net loss per share were as follows (in thousands, except loss per share data):

On June 30, 2011 and 2010, we excluded the following convertible securities from diluted net loss per share, as the effect of including them would have been anti-dilutive: publicly traded warrants exercisable for 6,025,000 and 6,025,000 shares of common stock, respectively, options and private warrants exercisable into a total of 10,416,000 and 13,415,000 shares of common stock, respectively, and 1,017,000 and 485,000 shares of nonvested equity shares, respectively.
