Earnings Per Share [Abstract]

Loss Per Share

10. Loss Per Share

The Company calculates basic (loss) earnings per share by dividing net (loss) income by the weighted average number of common shares outstanding. The Company computes diluted (loss) earnings per share after giving consideration to the dilutive effect of stock options and unvested restricted stock that are outstanding during the period, except where such securities would be anti-dilutive.

Basic and diluted loss per share was calculated as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
	(In thousands)
Net loss	$	(23,634	)	$	(22,702	)	$	(71,257	)	$	(66,277	)
Weighted average shares outstanding, basic    and diluted		48,554			43,161			46,547			42,684
Net loss per share, basic and diluted	$	(0.49	)	$	(0.53	)	$	(1.53	)	$	(1.55	)

The following common stock equivalents were excluded from the calculation of diluted loss per share because their inclusion would have been anti-dilutive: 

	Nine Months Ended September 30,

Unvested restricted stock		72		144
