* | The Company revised the presentation of previously reported amounts to be consistent with the presentation for the year ended January 31, 2015. The changes resulted in decreases to net sales, gross margin and selling, general, and administrative expenses for the quarters ended January 31, 2015 and 2014, respectively.
** Net loss per share was calculated based on basic shares outstanding due to the anti-dilutive effect on the inclusion of common stock equivalent shares.
