Note 3 — Net Income (Loss) Per Share

Basic net income (loss) per share (EPS) is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period, including vested restricted stock units (RSUs).

In periods with a net income, diluted EPS is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of dilutive restricted stock units. Dilutive restricted stock units are calculated based on the average share price for each fiscal period using the treasury stock method. For RSUs with performance-based vesting, no common equivalent shares are included in the computation of diluted EPS until the related performance criteria have been met. In periods with a net loss, common equivalent shares are not included in the computation of diluted EPS, because to do so would be anti-dilutive.

The weighted-average number of shares outstanding used to compute net income (loss) per common share were as follows (in thousands):
