Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Basic net earnings per share are computed using the weighted-average number of common shares outstanding. The dilutive effect of potential common shares outstanding is included in diluted net earnings per share. The computations of basic net earnings per share and diluted net earnings per share are as follows:

Stock awards to purchase 1,014,000 shares of common stock having average exercise price of $29.22 per common share were outstanding during the three months ended March 31, 2015 but not included in the computation of diluted earnings per common share because the exercise prices of the options were greater than the average market price of the common shares, and therefore, would be antidilutive.

Stock awards to purchase 993,000 shares of common stock having an average exercise price of $25.87 per common share were outstanding during the three months ended March 31, 2014 but not included in the computation of diluted earnings per common share because the exercise prices of the options were greater than the average market price of the common shares, and therefore, would be antidilutive.
