NOTE 4— NET INCOME (LOSS) PER COMMON SHARE

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. The 50,000 contingently issuable/restricted shares related to the acquisition of CCI were excluded from basic and diluted earnings per share since the contingency had not been met as of the reporting period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that would share in the net income of the Company. For the year ended December 31, 2016, the effect of 34,374 stock appreciation rights (“SARs”) have not been considered in the diluted earnings per share, since the market price of the stock was less than the exercise price during the period in the computation. For the year ended December 31, 2015 and 2014, the effect of 0.1 million SARs have not been considered in the diluted earnings per share, since the market price of the stock was less than the exercise price during the period in the computation.

The following tables set forth the computation of basic and diluted earnings (loss) per share:
