Net Earnings Per Share

Basic net earnings per share is computed by dividing net earnings available for basic common shares by the weighted average number of shares of common stock outstanding. Diluted net earnings per share is computed by dividing net earnings available for diluted common shares by the sum of weighted average number of shares of common stock outstanding and dilutive potential common stock. Diluted net earnings per share is calculated using the “if-converted” treasury stock method.
