Earnings per Share

Reconciliation of the numerators and denominators of the earnings per share calculations —



	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Net income available to common stockholders - Numerator basic and diluted	$	111	$	95	$	141	$	327

Denominator:
Weighted-average common shares outstanding - Basic	144.0		144.7		144.0		145.1
Employee compensation-related shares, including stock options	0.8		1.2		0.8		1.5
Weighted-average common shares outstanding - Diluted	144.8		145.9		144.8		146.6

The share count for diluted earnings per share is computed on the basis of the weighted-average number of common shares outstanding plus the effects of dilutive common stock equivalents (CSEs) outstanding during the period. We excluded 0.6 million and 0.1 million CSEs from the calculation of diluted earnings per share for the third quarters of 2019 and 2018 and excluded 0.2 million and 0.1 million of CSEs for the respective year-to-date periods as the effect of including them would have been anti-dilutive.
