Earnings Per Share [Abstract]

Net Income (loss) per share

Net Income per share

Basic net income per common share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period, without consideration for common stock equivalents. Outstanding stock options, unvested RSAs, unvested RSUs, unvested PSUs, common shares expected to be issued under our ESPP and the Convertible Notes are considered common stock equivalents and are only included in the calculation of diluted earnings per common share when net income is reported and their effect is dilutive.

Potentially dilutive common shares issuable upon vesting of stock options, RSAs, RSUs and PSUs are determined using the average share price for each period under the treasury stock method. Potentially dilutive common shares issuable upon conversion of our Convertible Notes are determined using the if-converted method. Since we have committed to settle the principal amount of the Convertible Notes in cash upon conversion only, the number of shares for the conversion spread will be included as a dilutive common stock equivalent.

A reconciliation of the numerators and the denominators of the basic and diluted net income per common share computations is as follows (in thousands, except per share amounts):
