7.	Loss Per Share

The Company calculates basic (loss) earnings per share by dividing (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 June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(In thousands)
Net loss	$	(22,219	)	$	(15,593	)	$	(43,575	)	$	(28,224	)
Weighted average shares outstanding, basic and diluted		42,836			34,916			42,441			34,820
Net loss per share, basic and diluted	$	(0.52	)	$	(0.45	)	$	(1.03	)	$	(0.81	)

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

	Periods Ended June 30,
	2018		2017
	(In thousands)
Unvested restricted stock		261		982
Stock options		4,881		4,499
Total		5,142		5,481
