Earnings Per Share [Abstract]  
Net Income (Loss) per Share Net Income (Loss) per Share
The Company applies the two-class method to calculate its basic and diluted net loss per share as Class A subordinate voting shares and Class B restricted voting shares are participating securities with equal participation rights and are entitled to receive dividends on a share for share basis. The Company uses the treasury stock method and if-converted method for calculating the effect of dilutive potential common stock from employee stock options and employee RSUs and from its Notes, respectively.
The following table summarizes the reconciliation of the basic weighted average number of shares outstanding and the diluted weighted average number of shares outstanding:
