At June 30, 2020 and 2019, the Company’s potentially dilutive securities were preferred stock, unvested restricted stock and stock options, which have been excluded from the computation of diluted net loss per share attributable to common stockholders for the three and six months ended June 30, 2020 and 2019, as the effect would be to reduce the net loss per share attributable to common stockholders. Based on the amounts outstanding at June 30, 2020 and 2019, the Company excluded the following potential common shares from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect:
