The computations of basic and diluted earnings per share is as follows:
Three Months Ended September 30,
Nine Months Ended September 30,
2020
2019
2020
2019
(in millions, except per share amounts)
Numerator:
Net income
$(140)$543 $1,357 $1,430 
Denominator:
Basic: Weighted-average common shares outstanding
123.0 132.7 124.8 135.8 
Effect of potentially dilutive nonqualified stock options and other share-based awards
1.9 1.8 1.7 1.7 
Diluted: Weighted-average common shares outstanding
124.9 134.5 126.5 137.5 
Earnings per share:
Basic
$(1.14)$4.09 $10.87 $10.53 
Diluted
$(1.14)(1)$4.04 $10.73 $10.40 
(1) Diluted shares used in this calculation represent basic shares due to the net loss. Using actual diluted shares would result in anti-dilution.
The calculation of diluted earnings per share excludes the incremental effect of 1.5 million and 1.0 million options as of September 30, 2020 and 2019, respectively, due to their anti-dilutive effect.
