Note 11 - Loss Per Share | 12 Months Ended

Earnings Per Share [Text Block] | 11. Loss Per Share We calculate basic loss per share by dividing net loss by the weighted average number of common shares outstanding during the reporting period. Diluted loss per share reflect the effects of potentially dilutive securities. Because we incurred net losses for the fiscal years ended January 31, 2013 and 2012, basic and diluted loss per share were the same because the inclusion of 330,000 and 120,000, as of January 31, 2013 and 2012, respectively, potential common shares related to outstanding stock awards in the calculation would have been antidilutive. The summary of the basic and diluted earnings per share computations is as follows (in thousands, except per share data):
