    2012     2011

(1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding.
(2) Options to purchase 466,915 and 234,639 shares of Common Stock for the three months ended March 31, 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.
