[1] For the years ended December 31, 2019, 2018 and 2017, there were net losses allocable to common shareholders, so the effect of common share equivalents of 452, 203 and 93 for the years ended December 31, 2019, 2018 and 2017, respectively, is excluded from the calculation of diluted loss per share, as their inclusion would be anti-dilutive.
