Earnings Per Common Share

Earnings 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 3.1 million shares, 3.0 million shares, and 2.8 million shares, for the years ended December 31, 2012, 2011, and 2010, respectively.

The computation of basic and diluted net income attributable to Trinity Industries, Inc. follows. Amounts previously reported have been adjusted to reflect discontinued operations resulting from the expected sale of the Company's ready-mix concrete operations. See Note 2 Acquisitions and Divestitures.
