Earnings Per Share [Abstract]

Schedule of earnings per share basic and diluted

Basic earnings per share, which excludes dilution, is computed by dividing net income available to common shareholders 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.
