[1] Potentially dilutive securities consist of unvested restricted stock awards, warrants and convertible preferred stock. Because the Company is reporting a loss from continuing operations attributable to common shareholders for the years ended December 31, 2021 and December 31, 2020, all potentially dilutive securities outstanding were excluded from the calculation of diluted loss from continuing operations per share since their inclusion would have been anti-dilutive.
