Earnings Per Share [Abstract]

Earnings per Share

11. EARNINGS PER SHARE

We compute basic earnings per common share by dividing net income attributable to Core Laboratories N.V. by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the incremental effect of contingently issuable shares from performance and restricted stock awards, as determined using the treasury stock method. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of basic and diluted earnings per share (in thousands):
