(1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding.
(2) Options to purchase 861,958 and 733,120 shares of Common Stock for the three and six months ended June 30, 2013, respectively, were not included in the calculation of net loss per share as the effect would have been antidilutive. Options to purchase 536,173 and 1,682,021 shares of Common Stock for the three and six months ended June 30, 2012, 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.
