Earnings Per Share [Abstract] |
Earnings per Common Share | Earnings Per Common Share Basic earnings per common share is computed by dividing net income remaining after allocation to participating unvested restricted shares, which includes unvested restricted shares of Arcosa stock held by employees of our former parent, Trinity Industries, Inc., by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted earnings per common share includes the weighted average net impact of nonparticipating unvested restricted shares. Total weighted average restricted shares were 1.1 million and 1.3 million for the three and nine months ended September 30, 2023, respectively. Total weighted average restricted shares were 1.4 million and 1.5 million for the three and nine months ended September 30, 2022, respectively. The computation of basic and diluted earnings per share follows.
