6.	Earnings Per Share

Basic earnings per share ("EPS") excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive stock options and restricted stock units).

The following is a reconciliation of basic and diluted EPS for the periods presented in the unaudited interim consolidated statements of income:

There were 1,500 and 1,144 stock options for the six months ended June 30, 2018 and June 30, 2017, respectively, that were not considered in the calculation of diluted EPS since the stock options’ exercise price was greater than the average market price during these periods.
