Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common ShareBasic earnings per common share (“EPS”) and diluted EPS are calculated by dividing net income attributable to Tutor Perini Corporation by the following: for basic EPS, the weighted-average number of common shares outstanding during the period; and for diluted EPS, the sum of the weighted-average number of both outstanding common shares and potentially dilutive securities, which for the Company can include restricted stock units, unexercised stock options and the Convertible Notes, as defined in Note 9. In accordance with ASC 260, Earnings Per Share, the settlement of the principal amount of the Convertible Notes has no impact on diluted EPS because the Company has the intent and ability to settle the principal amount in cash. See Note 9 for further discussion of the Convertible Notes. The Company calculates the effect of the potentially dilutive restricted stock units and stock options using the treasury stock method.
