NET INCOME (LOSS) PER SHARE

9 Months Ended

Sep. 30, 2020

Basic net (loss) income per share is calculated by dividing the net (loss) income by the weighted-average number of shares of common stock outstanding during the period. Diluted net (loss) income per share is calculated by dividing the net income by the weighted-average number of shares of common stock outstanding during the period, plus potentially dilutive common shares, consisting of stock options and convertible debt. The 12,430,913 shares of common stock issuable upon the exercise of warrants are included in the number of outstanding shares used for the computation of basic and diluted loss per share (see Note 2, Acquisitions). The Company uses the treasury-stock method to compute diluted earnings per share with respect to its stock options and equivalents. The Company uses the if-converted method to compute diluted earnings per share with respect to its convertible debt. For purposes of this calculation, options to purchase stock are considered to be potential common shares and are only included in the calculation of diluted net (loss) income per share when their effect is dilutive. The following table reflects the calculation of basic and diluted earnings per common share for the three and nine ended September 30, 2020 and 2019 (in thousands, except for per share amounts):

The following table reflects outstanding potentially dilutive common shares that are not included in the computation of diluted net income (loss) per share, because to do so would be anti-dilutive, for the three and nine months ended September 30, 2020 and 2019 (in thousands):
