Earnings Per Share [Abstract]

Earnings (Loss) Per Share

5. Earnings (Loss) Per Share

Basic earnings (loss) per share (“EPS”) is calculated in accordance with Accounting Standards Codification (“ASC”) 260, “Earnings Per Share,” by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and warrants. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future were not included in the computation of diluted EPS because to do so would have been antidilutive. The calculations of basic and diluted net loss per share are as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Net loss (numerator)	$	(19,583	)	$	(15,884	)	$	(57,968	)	$	(53,671	)
Weighted-average shares, in thousands (denominator)		139,589			138,586			139,025			138,344
Basic and diluted net loss per share	$	(0.14	)	$	(0.12	)	$	(0.42	)	$	(0.39	)

Potentially dilutive securities outstanding consists solely of outstanding stock options. The Company had stock options outstanding to purchase 14,979 and 15,569 shares of common stock, respectively, as of September 30, 2019 and 2018, respectively.
