EARNING (LOSS) PER SHARE [Abstract]

EARNING (LOSS) PER SHARE

NOTE 11 - EARNING (LOSS) PER SHARE

The computation of basic earnings (loss) per share of common stock is based on the weighted average number of shares outstanding during the years. The computation of diluted earnings per common share is based on the weighted average number of shares outstanding during the year plus the common stock equivalents that would arise from the exercise of stock options and warrants outstanding under the treasury method and the average market price per share during the year. Common stock equivalents at December 31, 2012 consisted of 21,660,400 of which 15,455,470 were in options and 6,204,930 were in warrants. Common stock equivalents at December 31, 2011 consisted of 18,022,188 of which 11,598,411 were in options and 6,423,777 were in warrants. Common stock equivalents at December 31, 2010 consisted of 8,173,464, of which 7,593,277 in options and 580,187 in warrants. Common stock equivalents during 2010 through 2012 were not included in the computation of loss per share because they would have been anti-dilutive.
