Note 8. Earnings Per Share
Prior to the completion of the Company’s initial public offering, the holders of the Company’s Series A Preferred Stock were entitled to participate with common stockholders in the distribution of earnings through dividends. Therefore, the Company applies the two-class method in calculating earnings per common share. The two-class method requires net income, after accretions in the carrying value of Series A Preferred Stock, to be allocated between the common and preferred stockholders based on their respective rights to receive dividends, whether or not declared. Basic earnings per common share is then calculated by dividing net income allocated to common stockholders, after the reduction for earnings allocated to Series A Preferred Stock, by the weighted-average common shares issued and outstanding.
Diluted earnings per common share is calculated by dividing net income allocated to common stockholders by the weighted-average number of common shares issued and outstanding for each period plus amounts representing the dilutive effect of outstanding stock options and restricted stock, and the dilution resulting from the conversion of Series A Preferred Stock. The Company calculates dilutive potential common shares using the treasury stock method, the if-converted method and the two-class method.
The following table sets forth the computation of the basic and diluted earnings per common share:
