Net Loss Per Share [Abstract]

Net Loss Per Share

4. Net Loss Per Share

Our basic net loss per share amounts are computed by dividing net loss by the weighted-average number of common shares outstanding during the period. At the end of the 2012 periods presented below, 33,627 shares of unvested restricted stock with non-forfeitable rights to dividends were outstanding; all such shares were vested at the end of June 30, 2013 period. The allocation of 2012 net losses to these participating securities pursuant to the two-class method is not material to both basic and diluted earnings per share. For each of the periods presented below, we reported a net loss and, therefore, potential dilutive common shares were not included in computing diluted net loss per share since it 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, 2013
Basic and diluted	$	(12,263	)		51,481	$	(0.24	)
Six months ended June 30, 2013
Basic and diluted	$	(23,521	)		50,802	$	(0.46	)
Three months ended June 30, 2012
Basic and diluted	$	(10,720	)		33,798	$	(0.32	)
Six months ended June 30, 2012
Basic and diluted	$	(23,806	)		33,779	$	(0.70	)

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