(1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding.
(2) Options to purchase 550,655 and 366,833 shares of Common Stock for the three months ended September 30, 2012 and 2011, respectively, and options to purchase 490,585 and 259,047 shares of Common Stock for the nine months ended September 30, 2012 and 2011, respectively, were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of the Common Stock and, therefore, the effect would be antidilutive.
