Earnings Per Share [Abstract]

Net Income per Share

Net Income per Share

Basic earnings per share is based on the weighted average number of shares of common stock outstanding, and diluted earnings per share is based on the weighted average number of shares of common stock outstanding and all potentially dilutive common stock equivalents outstanding. Common stock equivalents are included in the per share calculations when the effect of their inclusion is dilutive.

The following is a reconciliation of basic to diluted net income per share:
