Earnings per share is based on weighted average number of outstanding common shares. Basic earnings per share excludes the impact of dilutive securities and is computed by dividing Net income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

The following table presents the income and share data used in the basic and diluted earnings per share computations.
