4. Basic and Diluted Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The number of dilutive common equivalent shares outstanding during the period was determined in accordance with the treasury-stock method. Common equivalent shares consisted of common stock issuable upon the exercise of outstanding options and common stock issuable upon the vesting of outstanding, unvested SUAs. Basic and diluted weighted average common shares outstanding for the three and six months ended June 30, 2017 are as follows:
