Net Income Attributable to Trinity Industries, Inc. Per Common Share

Note 17. Net Income Attributable to Trinity Industries, Inc. Per Common Share

     Basic net income attributable to Trinity Industries, Inc. per common share is computed by dividing net income attributable to Trinity remaining after allocation to unvested restricted shares by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted net income attributable to Trinity per common share includes the net impact of unvested restricted shares and shares that could be issued under outstanding stock options. Total weighted average restricted shares and antidilutive stock options were 2.9 million shares for the three and nine month periods ended September 30, 2011. Total weighted average restricted shares and antidilutive stock options were 2.8 million shares for the three and nine month periods ended September 30, 2010.
