Earnings per share

13 Earnings per share

The Company calculates basic earnings per share (EPS) by dividing net income attributable to controlling interest by the weighted-average number of shares of common stock outstanding for the period (net of treasury shares). When it would not be antidilutive (such as during periods of net loss), the diluted EPS also reflects the potential dilution that could occur if common stock were issued for awards under the Stock Incentive Plan.

For the three and nine months ended September 30, 2015, approximately 0.2 million and 0.2 million shares of common stock, respectively, were not included in the computation of the diluted EPS, which could potentially dilute basic EPS in the future. For the three and nine months ended September 30, 2014, There were no common shares excluded from the computation of the diluted EPS, which could potentially dilute basic EPS in the future.

During the three months ended September 30, 2015 and September 30, 2014 approximately 24 thousand and 20 thousand shares of common stock, respectively, from the treasury stock have been utilized by the Stock Incentive Plan. During the nine months ended September 30, 2015 and September 30, 2014 approximately 0.3 million and 0.4 million shares of common stock, respectively, from the treasury stock have been utilized by the Stock Incentive Plan.
