Earnings Per Share

6 Months Ended

Jun. 30, 2019

Earnings per share

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share is computed similar to basic earnings per share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The computations for basic and diluted earnings (loss) per share are as follows:

	Three Months Ended						Six Months Ended
(shares in thousands)	June 30,						June 30,
	2019			2018			2019			2018
