EARNINGS (LOSS) PER SHARE

We calculate basic earnings (loss) per share by dividing net income (loss) by the weighted average number of common shares outstanding. Shares issuable upon the satisfaction of certain conditions are considered outstanding and included in the computation of basic earnings (loss) per share. The following table shows the computation of basic and diluted earnings (loss) per share:
