Earnings (Loss) Per Share

9 Months Ended

Sep. 30, 2019

Basic net income per share is computed by dividing net income, less any dividends, accretion or decretion, redemption or induced conversion on the preferred stock, by the weighted average number of common shares outstanding during the period. As the preferred stock participates in dividends alongside the Company’s common stock (per their participating dividends), the preferred stock would constitute participating securities under ASC 260-10 and are applied to earnings per share using the two-class method. Under this method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights to receive dividends.

Diluted net income per share is calculated using the more dilutive of the if-converted or the two-class method. For the three and nine months ended September 30, 2019 and 2018, the two-class method was more dilutive and was computed by adjusting the denominator used in the basic net income per share computation by the weighted average number of common shares outstanding and potentially dilutive securities outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options, shares issuable upon vesting of RSAs, RSUs, PBRSUs and shares issuable upon conversion of preferred stock.

Basic and diluted net income (loss) per common share are calculated as follows (in millions, except share and per share data):

Because of their anti-dilutive effect, 1,480,903 common share equivalents comprised of stock options, PBRSUs, and RSUs have been excluded from the diluted earnings per share calculation for the three months ended September 30, 2019.

For the nine months ended September 30, 2019, 22,795,316 common share equivalents have been excluded from the diluted earnings per share calculation because of their anti-dilutive effect. For the three and nine months ended September 30, 2018, 21,952,446 common share equivalents have been excluded from the diluted earnings per share calculation because of their anti-dilutive effect. Additionally, for the nine months ended September 30, 2019 and the three and nine months ended September 30, 2018, the Investor's and Intermountain's exercisable warrants to acquire up to 60 million and 1.5 million shares, respectively, of the Company's common stock have been excluded from the diluted earnings per share calculation because they are anti-dilutive for all periods presented.
