Restricted stock and restricted stock unit awards of 257,280 and 1,343,781 for the three months ended March 31, 2019 and 2018, respectively, which are contingent upon the Company meeting a cumulative three year earnings target and contingent upon continued employment, are excluded from the computation of diluted income per common share as the contingencies were not satisfied at March 31, 2019 and 2018, respectively. In addition, there were 95,000 shares of Preference Shares outstanding which were convertible into 15,081,035 and 10,337,949 Class A common shares at March 31, 2019 and 2018, respectively and 50,000 Preference Shares outstanding which were convertible into 10,037,778 Class A common shares at March 31, 2019. These Preference Shares were anti-dilutive for the three months ended March 31, 2019 and 2018 and are therefore excluded from the diluted loss per common share calculation.
