Net income (loss) per share of common stock:

Income (Loss) Per Common Share

Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the weighted average number of common shares outstanding during the period plus the effect of potentially dilutive common stock equivalents, including warrants to purchase the Company's common stock and convertible preferred stock. Management has determined that the calculation of diluted earnings per share for the three and six month periods ended June 30, 2017 and June 30, 2016, is not applicable since any additions to outstanding shares related to common stock equivalents would be anti-dilutive.

As of June 30, 2017 and 2016, the potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share as their effect would have been anti-dilutive are as follows:

	June 30, 2017		June 30, 2016
Warrants		250,000		250,000
Convertible preferred stock		1,751,005		1,751,005
Total possible dilution		2,001,005		2,001,005
