Earnings per Share

Note 4 Earnings Per Share

Basic earnings per share are computed by dividing net income by the weighted average number of shares of stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential Common Stock outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be issued from the exercise of Common Stock equivalents.

The following summarizes the Common Stock included in the basic and diluted shares, as disclosed on the face of the consolidated condensed statements of income:
