10.	Loss Per Share

The Company calculates basic loss per share by dividing net loss for each respective period by the weighted average number of common shares outstanding for each respective period. The Company computes diluted loss 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,
	2020			2019			2020			2019
	(In thousands)
Net loss	$	(32,393	)	$	(25,683	)	$	(64,199	)	$	(47,623	)
Weighted average shares outstanding, basic and diluted		53,369			45,814			51,938			45,526
Net loss per share, basic and diluted	$	(0.61	)	$	(0.56	)	$	(1.24	)	$	(1.05	)

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