Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. For those securities that are not convertible into a class of common stock, the “two-class” method of computing income (loss) per share is used.

Options to purchase 6.9 million shares and 3.5 million shares of common stock for the three months ended September 30, 2019 and 2018, respectively, were outstanding but not included in the computation of diluted income (loss) per share because the exercise price of the options was greater than the average market price of the common shares and therefore the effect would have been anti-dilutive. Options to purchase 6.9 million shares and 5.5 million shares of common stock for the nine months ended September 30, 2019 and 2018, respectively, were outstanding but not included in the computation of diluted net loss per share because the effect would have been anti-dilutive.
