Net Income (loss) Per Share

Net income (loss) per share is computed by dividing the net amount excluding net income (loss) attributable to a non-controlling interest by the weighted average number of common shares outstanding during the year. Diluted net income (loss) per share reflects the potential dilution that could occur from common shares issuable through stock options, warrants, and other convertible securities. For the year ended December 31, 2018, stock options of 6,792,000 and warrants of 1,200,000 are included in the calculation of diluted income per share. Excluded from the diluted earnings per share calculation were 262,500 options and 12,900,123 warrants. For the year ended December 31, 2017, stock options of 2,750,000 and warrants of 1,200,000 are included in the calculation of diluted income per share. Excluded from the diluted earnings per share calculation were 4,912,500 options and 8,095,834 warrants. These options and warrants are excluded when the exercise prices were greater than the average trading prices of the Company’s common stock for the respective period.
