Anti-dilutive stock awards 2,835,770 1,633,464

Restricted stock and restricted stock unit awards of 2,203,717 and 257,280 as of March 31, 2020 and 2019 respectively, are excluded from the computation of diluted income (loss) per common share because the performance contingency necessary for vesting has not been met as of the reporting date or all the terms and conditions to establish a grant date were not yet known. In addition, there were 145,000 Preference Shares outstanding which were convertible into 27,189,411 and 25,118,813 Class A common shares at March 31, 2020 and 2019, respectively. These Preference Shares were anti-dilutive for each period presented in the table above and are therefore excluded from the diluted income (loss) per common share calculation.
