Earnings Per Share [Abstract]  
Net Loss Per Common Share Net Loss Per Common Share

Basic net loss per common share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period.
 
Diluted net loss per common share is computed by giving effect to all potential shares of common stock, including stock options, restricted stock units, market stock units, performance-based RSUs, potential ESPP shares and instruments convertible into common stock, to the extent dilutive. For the three and nine months ended September 30, 2017 and 2018, basic net loss per common share was the same as diluted net loss per common share, as the inclusion of all potential common shares outstanding would have been anti-dilutive.
 
The following table sets forth the computation of historical basic and diluted net loss per common share:

On December 9, 2015, we completed an offering of our 1.75% convertible senior notes due 2020. As we have the intention to settle the 2020 Notes either partially or wholly in cash, under the treasury stock method, the 2020 Notes will generally have a dilutive impact on earnings per share if we are in a net income position for the period and if our average stock price for the period exceeds approximately $16.42 per share of our common stock, the conversion price of the 2020 Notes. For the period from the issuance of the offering of the 2020 Notes through September 30, 2018, the conversion feature of the 2020 Notes was anti-dilutive, as we were in a net loss position for all periods and our average stock price was less than the conversion price.

In connection with the pricing of the 2020 Notes, we entered into Capped Call Transactions which increase the effective conversion price of the 2020 Notes, and are designed to reduce potential dilution upon conversion of the 2020 Notes. Since the beneficial impact of the capped call is anti-dilutive, it is excluded from the calculation of earnings per share. Refer to Note 11 "Debt Instruments" for further details regarding our 2020 Notes.
