Net Income Per Share [Text Block]

Net Income Per Share:

Net income per share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average number of common shares outstanding plus dilutive securities. Dilutive securities are outstanding common stock options and restricted stock units(excluding stock options with an exercise price in excess of the average market value for the period), less the number of shares that could have been purchased with the proceeds from the exercise of the options, using the treasury stock method. Options that are anti-dilutive because their exercise price exceeded the average market price of the common stock for the period approximated 295,000 for the three months ended September 30, 2011 and 5,000 and 189,000 for the nine months ended September 30, 2012 and 2011, respectively.

The following table presents the calculation of net earnings per common share (“EPS”) — basic and diluted.
