Earnings Per Share [Abstract] |
Earnings Per Share [Text Block] | Note 15 - Earnings Per Share The following table sets forth the computation of basic and diluted earnings per share (“EPS”) (number of shares in thousands):
Year Ended |  | January 31, 2016 |  |  | January 31, 2015 |  |  | January 31, 2014 |
Net income for purposes of calculating basic and diluted earnings per share |  |  | 20,562 |  |  |  | 15,059 |  |  |  | 9,612 |
Weighted average shares outstanding |  |  | 75,595 |  |  |  | 70,559 |  |  |  | 62,841 |
Dilutive effect of employee stock options |  |  | 452 |  |  |  | 665 |  |  |  | 1,258 |
Dilutive effect of restricted and performance share units |  |  | 362 |  |  |  | 360 |  |  |  | 271 |
Weighted average common and common equivalent shares outstanding |  |  | 76,409 |  |  |  | 71,584 |  |  |  | 64,370 |
Earnings per share |  |  |  |  |  |  |  |  |  |  |  |
Basic |  |  | 0.27 |  |  |  | 0.21 |  |  |  | 0.15 |
Diluted |  |  | 0.27 |  |  |  | 0.21 |  |  |  | 0.15 |
For the years ended January 31, 2016, 2015 and 2014, nil options were excluded from the calculation of diluted EPS as those options had an exercise price greater than or equal to the average market value of our common shares during the applicable periods and their inclusion would have been anti-dilutive. Additionally, for 2016, 2015 and 2014, respectively, the application of the treasury stock method excluded nil, 215,000 and nil options, restricted and performance share units from the calculation of diluted EPS as the assumed proceeds from the unrecognized stock-based compensation expense that are attributed to future service periods made such stock-based compensation anti-dilutive.
