Earnings Attributable to Ecolab Per Common Share

11. EARNINGS ATTRIBUTABLE TO ECOLAB PER COMMON SHARE (“EPS”)

The difference in the weighted average common shares outstanding for calculating basic and diluted EPS is a result of the dilution associated with the company’s equity compensation plans. As noted in the table below, certain stock options and units outstanding under these equity compensation plans were not included in the computation of diluted EPS because they would not have had a dilutive effect.

The computations of the basic and diluted EPS amounts were as follows:
