Earnings Per Share

3 Months Ended

Mar. 31, 2020

2.	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 per share are as follows:

Earnings per share from continuing operations — diluted	$	0.52	$	0.32

For the three months ended March 31, 2019, 66 stock options (“NQSOs”) and restricted stock units (“RSUs”) were excluded from the calculation of diluted earnings per share based on the application of the treasury stock method, as such NQSOs and RSUs were determined to be anti-dilutive.
