At December 31, 2019, there are no dividends accumulated on the Company’s SBCPS. At December 31, 2018, dividends accumulated on the Company’s SBCPS totaled $41,000.

Basic loss per common share is computed by dividing net loss attributable to common shares by the weighted average number of common shares outstanding for the period. Diluted loss per common share is computed by dividing net loss attributable to common shares, by the weighted average number of common shares outstanding, adjusted for shares that would be assumed outstanding after warrants and stock options vested under the treasury stock method.

At December 31, 2019 and 2018, outstanding warrants exercisable into 260,000 and 5,680,000 shares of Common Stock, respectively, were excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.
