Earnings Per Share [Abstract]

Schedule of Earnings Per Share, Basic and Diluted [Table Text Block]

The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands except per share amounts):

		2017			2016			2015
Numerator:
Net loss		$	(2,139)		$	(12,129)		$	(6,533)
Denominator:
Weighted average common shares and denominator for basic calculation:
Weighted average common shares outstanding			41,025			40,352			39,384
Less: Unvested restricted stock			(21)			(23)			(124)
Denominator for basic calculation			41,004			40,329			39,260
Weighted average effects of potentially dilutive common stock:			—			—			—
Denominator for diluted calculation			41,004			40,329			39,260
Net loss per share – basic and diluted		$	(0.05)		$	(0.30)		$	(0.17)

Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share [Table Text Block]

Because the Company had a net loss for the years ended December 29, 2017, December 30, 2016 and January 1, 2016, the number of diluted shares is equal to the number of basic shares. Outstanding options and warrants to purchase common stock, restricted stock and restricted stock units would have had an anti-dilutive effect on diluted per share amounts. The following table sets forth (in thousands) the weighted average number of options and warrants to purchase shares of common stock, restricted stock, and restricted stock units with either exercise prices or unrecognized compensation cost per share greater than the average market price per share of the Company’s common stock, which were not included in the calculation of diluted per share amounts because the effects would be anti-dilutive.

		2017			2016			2015
Options			2,237			4,069			2,506
Warrants			—			—			345
Restricted stock and restricted stock units			203			76			190
Total			2,440			4,145			3,041

- Definition

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
