Basic earnings per common share is calculated using the weighted average shares of Common Stock outstanding during the period. Common equivalent shares from stock options, RSUs, warrants and convertible preferred stock using the treasury stock method, are also included in the diluted per share calculations unless the effect of inclusion would be antidilutive. During the years ended December 31, 2018, 2017 and 2016, outstanding stock options, RSUs, warrants and convertible preferred stock of 28,424,998, 6,531,346 and 10,228,929, respectively, were not included in the computation of diluted earnings per common share, because to do so would have had an antidilutive effect because the outstanding exercise prices were greater than the average market price of the common shares during the relevant periods. Included in the year ended December 31, 2018 are the Series B shares as converted to common stock.

The following is the total outstanding options, RSUs and warrants for the years ended December 31, 2018, 2017 and 2016, respectively.
