13.	EARNINGS (LOSS) PER SHARE - COMMON STOCK (“EPS”)

The Company’s basic EPS is calculated using net loss available to common shareholders and the weighted-average number of shares outstanding during the reporting period. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of convertible notes and preferred stock.

The reconciliation of the numerators of the basic and diluted EPS calculations was as follows for both of the following

three

and

nine

2018:

	Three Months ended September 30,						Nine Months ended September 30,
