Basic And Diluted Earnings Per Share |
Basic earnings per common share was computed by dividing net earnings attributable to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share reflects the potential dilution that would occur if all in-the-money outstanding options or other contracts to issue common stock were exercised or converted and was computed by dividing net earnings attributable to common stockholders by the weighted-average number of common shares outstanding plus dilutive common equivalent shares. During both the three and nine months ended January 31, 2012, SARs and options to purchase 0.6 million shares, were outstanding but not included in the computation of diluted earnings per share because they were anti-dilutive. During the three and nine months ended January 31, 2011, SARs and options to purchase 0.04 million shares and 0.8 million shares, respectively, were outstanding but not included in the computation of diluted earnings per share because they were anti-dilutive. The following table summarizes basic and diluted earnings per share calculations:
