3. Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, restricted stock units (“RSUs”), shares issued pursuant to the Employee Stock Purchase Plan (“ESPP”), performance restricted stock units (“PSUs”), and the Conversion Option of the 2025 Notes (the “Conversion Options”) (Note 9) are considered to be potential common stock equivalents.

Since the Company incurred net losses for each period presented, diluted net loss per share is the same as basic net loss per share. All of the Company’s outstanding stock options, RSUs, PSUs, and shares issuable under the ESPP, as well as the Conversion Options were excluded in the calculation of diluted net loss per share as the effect would be anti-dilutive.

The Company uses the if-converted method when calculating any potential dilutive effect of the Conversion Options, which assumes conversion of outstanding convertible securities at the beginning of the reporting period or date of issuance, if the convertible security was issued during the period.
