Net Earnings Per Share

 12.Net Earnings per Share

 

Basic net earnings per share is computed by dividing net earnings available for basic common shares by the weighted average number of shares of common stock outstanding.  Diluted net earnings per share is computed by dividing net earnings available for diluted common shares by the sum of weighted average number of shares of common stock outstanding and dilutive potential common  stock.   Diluted net earnings per share is calculated using the “if-converted” treasury stock method.

Certain options to purchase shares of common stock were outstanding and not included in the calculation of diluted net earnings per share because their inclusion would have been antidilutive.  On a weighted average basis, for the three months ended May 31, 2015 and 2014,  options to purchase 812,356 shares and 2,420,758 shares of common stock, respectively, were not included.
