Basic and Diluted Loss Per Common Share | BASIC AND DILUTED LOSS PER COMMON SHARE The calculation of basic and diluted earnings per share after adjustment for the effects of all potential dilutive common shares, is as follows:
| Three months ended March 31,
| 2019 |  | 2018
Loss attributable to shareholders | $ | (12,127 | ) |  | $ | (10,822 | )
Basic and diluted weighted average number of common shares outstanding | 92,152,844 |  |  | 75,209,456 |
Loss per common share | $ | (0.13 | ) |  | $ | (0.14 | )
For the three months ended March 31, 2019, 5.85 million (March 31, 2018 - 9.04 million) options and warrants and the potential conversion of the Debentures have been excluded from the calculation as their effect would have been anti-dilutive.
