Net Income Per Share

Net Income Per Share

Basic net income per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. The dilutive effect of outstanding options and restricted stock is reflected in diluted net income per share by application of the treasury stock method. The calculation of diluted net income per share excludes all anti-dilutive shares. The following table sets forth the computation of basic and diluted net income per share for the periods indicated:
