Basic earnings (loss) per share is computed by dividing earnings available to common stockholders by the weighted average number of shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares and potentially dilutive common shares outstanding during the period increased to include the number of additional shares of common stock that would be outstanding if the potentially dilutive securities had been issued. Potential common shares outstanding principally include stock options and warrants. During the years ended April 30, 2017 and 2016, the Company incurred losses.

The table below sets forth the basic loss per share calculations:
