Net Loss Per Share Attributable to Common Stockholders
Net Loss per common share
The Company computes basic earnings per share (EPS) by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding for the reporting period. Diluted EPS reflects the effect of potential shares that would be issued if stock option awards, Restricted Stock Units, Public and Private Warrants and preferred shares, to the extent issued, were converted into common stock, to the extent dilutive.
The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders:

Since the Company was in a net loss position for all periods presented, diluted net loss per share attributable to common stockholders will be the same as the basic net loss per share, as, in a net loss position, the inclusion of all potential common shares outstanding would be antidilutive. The potential shares of common stock excluded from the computation of diluted net loss per share for the periods presented due to their antidilutive impacts are as follows:

As of October 31, 2020 there were no Private or Public Warrants outstanding due to the fact that the Legacy LGL interim condensed consolidated balance sheet was consolidated and combined with Legacy IronNet as of the effective date of the Merger. Legacy LGL Public and Private Warrants as of August 26, 2021 were 8,624,992 and 5,200,000, respectively.

Net Loss Per Share Attributable to Common Shareholders
IronNet computes basic earnings per share (EPS) by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted EPS reflects the effect of potential shares that would be issued if stock option awards, restricted stock units, and preferred stock were converted into common stock, to the extent dilutive. Other than voting rights, the Class B common stock has the same rights as the Class A common stock and therefore both are treated as the same class of stock for the purposes of the earnings per share calculation.

Since the Company was in a net loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been
antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive are as follows:
