12. EARNINGS PER SHARE

The following table sets forth the components of the denominator for the computation of basic and diluted earnings per share for net income (loss) attributable to Community Health Systems, Inc. common stockholders:



	Three Months Ended
	March 31,
	2020		2019
Weighted-average number of shares outstanding — basic		114,301,519		113,257,608
Effect of dilutive securities:
Restricted stock awards		77,336		-
Employee stock options		476		-
Other equity-based awards		-		-
Weighted-average number of shares outstanding — diluted		114,379,331		113,257,608

The Company generated a loss attributable to Community Health Systems, Inc. common stockholders for the three months ended March 31, 2019, so the effect of dilutive securities is not considered because their effect would be antidilutive. If the Company had generated income during the three months ended March 31, 2019, the effect of restricted stock awards, employee stock options, and other equity-based awards on the diluted shares calculation would have been an increase in shares of 59,261.
