Net Loss per Share Attributable to Common Stock

Net Loss from Continuing Operations per Share Attributable to Common Stock

Net loss from continuing operations per share attributable to common stock is computed by dividing the net loss from continuing operations attributable to common stock by the weighted-average number of common shares outstanding. We have outstanding stock options, restricted stock units, options to purchase shares under our ESPP, convertible preferred stock, and convertible senior notes, which are considered in the calculation of diluted net loss from continuing operations per share whenever doing so would be dilutive.

We calculate basic and diluted net loss from continuing operations per share attributable to common stock in conformity with the two-class method required for companies with participating securities. We consider our convertible preferred stock to be a participating security. Under the two-class method, net loss from continuing operations attributable to common stock is not allocated to the preferred stock as its holders do not have a contractual obligation to share in losses, as discussed in Note 10.

The calculation of basic and diluted net loss per share attributable to common stock was as follows:

(1) Basic and diluted weighted-average shares outstanding include (i) common stock earned but not yet issued related to share-based dividends on our convertible preferred stock, and (ii) restricted stock units whose settlement into common stock were deferred at the option of certain non-employee directors.

The following outstanding shares of common stock equivalents were excluded from the computation of the diluted net loss from continuing operations per share attributable to common stock for the periods presented because their effect would have been anti-dilutive.
