Loss or Earnings Per Share	3 Months Ended
	Apr. 29, 2017
Earnings Per Share [Abstract]
Loss or Earnings Per Share	Note 3 — Loss or Earnings Per Share Basic loss or earnings per share is computed by dividing net loss or income by the weighted average number of shares outstanding during each period presented, which excludes non-vested restricted stock units. Diluted loss or earnings per share is computed by dividing net loss or income by the weighted average number of shares outstanding plus the dilutive effect of stock equivalents outstanding during the applicable periods using the treasury stock method. Diluted loss or earnings per share reflects the potential dilution that could occur if options to purchase stock were exercised into common stock and if outstanding grants of restricted stock were vested. Stock options and restricted stock units that were not included in the computation of diluted loss or earnings per share, because to do so would have been antidilutive, were approximately 1.4 million and 476,000 shares for the 13-week periods ended April 29, 2017 and April 30, 2016, respectively.
