14. Loss Per Share
Earnings per share are presented in accordance with authoritative guidance which requires the presentation of “basic” and “diluted” earnings per share. Basic earnings per share is computed by dividing earnings available to common shareholders by the weighted-average shares of common stock outstanding during the period. For the purposes of calculating diluted earnings per share, the denominator includes both the weighted average number of shares of common stock outstanding during the period and the weighted average number of shares of potential common stock, such as stock options and RSUs, calculated using the treasury stock method.
For the three months ended April 30, 2013 and 2012, there are 595,515 shares and 1,616,207 shares issuable upon the exercise of stock options that are anti-dilutive and have been excluded from the diluted earnings per share computation as the exercise prices of these common shares were above the market price of the common stock for the periods indicated. For the three months ended April 30, 2013 and 2012, 656,087 and 437,793 stock equivalents, respectively, have been excluded from diluted earnings per share due to the net loss.
Below is a summary of the shares used in calculating basic and diluted loss per share for the periods indicated:
