Earnings Per Share [Abstract]

Earnings Per Share

NOTE B – Earnings Per Share

Basic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted earnings per share is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.

The computation of basic and diluted earnings per common share is as follows (in thousands, except per share data):
