Earnings Per Share [Abstract]  
Earnings Per Common Share Earnings Per Common Share
Basic net income attributable to Trinity Industries, Inc. per common share ("EPS") is computed by dividing net income attributable to Trinity by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted EPS includes the net impact of potentially dilutive common shares. The Company has certain unvested RSAs that participate in dividends on a nonforfeitable basis and are therefore considered to be participating securities. Consequently, diluted net income attributable to Trinity Industries, Inc. per common share is calculated under both the two-class method and the treasury stock method, and the more dilutive of the two calculations is presented.
The following table sets forth the computation of basic and diluted net income attributable to Trinity Industries, Inc.
