Net Loss Per Share [Abstract]

Net Loss Per Share

3. Net Loss Per Share

Our basic net loss per share amounts have been computed by dividing net loss by the weighted-average number of common shares outstanding during the period. For each of the periods presented below, we reported net losses and, accordingly, potential common shares were not included since such inclusion would have been anti-dilutive. The calculations of net loss per share, basic and diluted, are as follows:

	Net Loss (Numerator)			Weighted Average Common Shares (Denominator) (in thousands)		Per Share Amount
Three months ended June 30, 2015
Basic and diluted	$	(11,697	)		69,647	$	(0.17	)
Six months ended June 30, 2015
Basic and diluted	$	(21,951	)		69,642	$	(0.32	)
Three months ended June 30, 2014
Basic and diluted	$	(11,073	)		69,561	$	(0.16	)
Six months ended June 30, 2014
Basic and diluted	$	(20,386	)		66,775	$	(0.31	)

For these periods, anti-dilutive common shares excluded from diluted per share amounts consist of the following:
