Through the amendment of its articles of incorporation on June 15, 2015, the Company introduced a dual class structure of common shares and class A shares and converted all outstanding common shares into class A shares; therefore, the weighted average number of shares for the year ended December 31, 2016 includes the average number of common shares and class A shares for the year ended December 31, 2016. Additionally, through an amendment of its article of incorporation effective as of March 31, 2016, the Company terminated its dual class structure of commons shares and class A shares and converted all class A shares into common shares. |
