Income (Loss) per Common Share

12 Months Ended

Dec. 31, 2021

Basic loss per common share is computed by dividing net loss (the numerator) by the weighted-average number of shares of common stock outstanding (the denominator) for the period. Diluted loss per common share assumes that any dilutive equity instruments were exercised with outstanding common stock adjusted accordingly when the conversion of such instruments would be dilutive.

For 2021, the Company's diluted loss per common share calculation considers the effect of 10,982,805 shares of Appgate’s common stock underlying the Convertible Senior Notes that is convertible at any time at the option of the holders of the Convertible Senior Notes prior to their maturity - see Note 11.

Weighted average shares of common stock outstanding has been retroactively restated for the equivalent number of shares received by the accounting acquirer as a result of the Merger as if these shares had been outstanding as of the beginning of the earliest period presented.

The following table summarizes the basic and diluted earnings per share calculations (in thousands, except per share amounts):
