Accounting Policies [Abstract]

Summary of Fair Value Assumptions

The principal assumptions used in applying the model were as follows:

	For Three and Six Months Ended June 30, 2017
Assumptions:
Risk-free interest rate	1.5%
Expected life	3 years
Expected volatility	60%
Dividends	0.0%

Schedule of Earnings Per Share, Basic and Diluted

Diluted net income (loss) per common share is based on the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding and computed as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2016			2017		2016
	(In thousands, except share and per share data)
Numerator:
Net income (loss) to common stockholders	$	(6,754	)	$	(4,582	)	$	9,195	$	(5,744	)
Denominator:
Weighted-average common shares, basic	23,257,492			22,764,322			23,195,775		22,736,505
Weighted-average common shares, diluted*	23,257,492			22,764,322			24,233,724		22,736,505
Net income (loss) per common share:
Basic:	$	(0.29	)	$	(0.20	)	$	0.40	$	(0.25	)
Diluted:	$	(0.29	)	$	(0.20	)	$	0.38	$	(0.25	)
* The diluted earnings per common share included 317,311 unvested Restricted Stock Units and the weighted average effect of 720,637 stock options that are potentially dilutive to earnings per share for the six months ended June 30, 2017, since the exercise price of such securities was less than the average market price during the period. For the three months ended June 30, 2017 and three and six months ended June 30, 2016, these securities would be anti-dilutive and were excluded.

Summary of Components Excluded from Computation of Diluted Net Loss Per Share

Potentially dilutive common shares from employee equity plans are determined by applying the treasury stock method to the assumed exercise of warrants and share options and were excluded from the computation of diluted net income (loss) per share because their inclusion would be anti-dilutive and consist of the following:

	June 30,
	2017	2016
Stock options	1,652,347	1,738,642
Warrants	2,309,136	—
Restricted Stock Units	317,311	469,902
Total	4,278,794	2,208,544
