2.	WEIGHTED AVERAGE COMMON SHARES

The weighted average number of common shares used to compute basic and diluted loss per share for the three and nine months ended September 30, 2017 and 2016 was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Basic shares outstanding		24,023,540		23,498,904		23,866,485		23,433,015
Dilutive effect of stock options		-		-		-		-
Diluted shares outstanding		24,023,540		23,498,904		23,866,485		23,433,015

For the three months ended September 30, 2017 and 2016, options to acquire 552,189 and 1,181,073 shares were excluded from the above table because the Company reported a net loss for each period and, therefore, their impact on reported loss per share would have been antidilutive. For the nine months ended September 30, 2017 and 2016, options to acquire 572,428 and 668,307 shares were excluded from the above table because the Company reported a net loss for each quarter and, therefore, their impact on reported loss per share would have been antidilutive. For the three and nine months ended September 30, 2017, options to acquire 170,667 shares were excluded from the above table because they have an exercise price that is greater than the average market price of the Company’s common stock and, therefore, their impact on reported income (loss) per share would have been antidilutive.
