Loss Per Share [Abstract]
Loss Per Share	12. LOSS PER SHARE Basic loss per share has been computed by dividing the net loss applicable to the Company's common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share is computed by including the dilutive effect of common stock that would be issued assuming exercise of the outstanding stock options and stock purchase warrants. Excluded from the computation of diluted loss per share for the three years ended December 31, 2011, 2010, and 2009 are shares underlying outstanding options because the effect would have been anti-dilutive as the Company incurred losses from continuing operations in each of these periods.

12. LOSS PER SHARE

Basic loss per share has been computed by dividing the net loss applicable to the Company's common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share is computed by including the dilutive effect of common stock that would be issued assuming exercise of the outstanding stock options and stock purchase warrants. Excluded from the computation of diluted loss per share for the three years ended December 31, 2011, 2010, and 2009 are shares underlying outstanding options because the effect would have been anti-dilutive as the Company incurred losses from continuing operations in each of these periods.
