Earnings Per Share [Abstract] |
Net Income per Share | Net Income per Share Basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average shares outstanding, including potentially dilutive shares of common equivalents outstanding during the period. The dilutive effect of potential shares of common stock is determined using the treasury stock method.
