Note 5: Net Income Per Share

Basic net income per common share is computed by dividing the net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted net income per share is calculated similarly to basic per share amounts, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive.

For periods presented in which there is a net loss, potentially dilutive securities are excluded from the computation of fully diluted net loss per share as their effect is anti-dilutive. Below is a reconciliation of the fully dilutive securities effect for the years ended December 31, 2021 and 2020 (in thousands, except per share data):
