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 266,000 and 9,000 for the three months ended June 30, 2014 and June 30, 2013, respectively. Options that are anti-dilutive because their exercise price exceeded the average market price of the common stock for the period approximated 235,000 and 5,000 for the six months ended June 30, 2014 and June 30, 2013, respectively.
