Note 7 — Net Income (Loss) Per Common Share

Basic net income (loss) per common share is computed by dividing net income (loss) by the basic weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share is computed by dividing net income (loss) by the diluted weighted average number of common shares and common equivalent shares outstanding during the period. The weighted average number of common equivalent shares outstanding has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable on the exercise of outstanding stock options and the vesting of restricted stock units.

Basic and diluted weighted average common shares are as follows (in thousands):
