Earnings Per Share [Abstract]

Schedule of earnings per share, basic and diluted

A reconciliation of the numerators and denominators of the basic and diluted earnings (loss) per share calculations were as follows:

	Three Months Ended
	March 31,
	2013			2012
Earnings (loss) per share ("EPS"):
Basic	$	(0.25	)	$	(0.10	)
Diluted	$	(0.25	)	$	(0.10	)
EPS numerator - basic and diluted:
Net income (loss)	$	(8,241	)	$	(3,221	)
EPS denominator (in thousands):
Weighted average common stock outstanding - basic	32,344			31,765
Common stock equivalents: stock options and other stock-based awards (a)	—			—
Weighted average number of common stock outstanding - diluted	32,344			31,765

(a) For the periods in which net losses are presented, the diluted weighted average number of shares of common stock outstanding did not differ from the basic weighted average number of shares of common stock outstanding because the effects of any potential common stock equivalents (see Note 5 for further details on outstanding stock options, unvested restricted stock units and unvested restricted stock) were anti-dilutive and therefore not included in the calculation of the denominator of dilutive earnings per share.

Schedule of antidilutive securities excluded from computation of earnings per share

The weighted average number of shares outstanding used in the computation of diluted net income (loss) per share for the three months ended March 31, 2013 and 2012 did not include the effect of the following potentially outstanding shares of common stock because the effect would have been anti-dilutive:

	Three Months Ended

	2013	2012
Unvested restricted stock	399,193	1,307,266
Unvested restricted stock units	100,000	100,000
Stock options	1,225,950	1,385,600
