(6) Earnings Per Common Share (EPS)

Basic 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 8, Financial Commitments. The Company calculates the effect of these potentially dilutive securities using the treasury stock method for restricted stock units and stock options.
