3.	Earnings per Share

Earnings per common share is presented under two formats: basic earnings per common share and diluted earnings per common share. Basic earnings per common share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period, plus the potentially dilutive impact of common stock equivalents (i.e. stock options and warrants). Dilutive common share equivalents consist of the incremental common shares issuable upon exercise of stock options and warrants. The following table sets forth the computation of basic and diluted net loss per share:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2017		2016		2017		2016

The following outstanding options and warrants were excluded from the computation of basic and diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2017		2016		2017		2016
Options to purchase common stock		2,361		2,422		2,361		2,422
Warrants to purchase common stock		1,362		1,749		1,362		1,749
