Earnings Per Share [Abstract]

Earnings per Share

Earnings per Share

Net income (loss) was used as the numerator in computing both basic and diluted income per Common share for each of the three years ended December 31, 2019.  The following table reconciles the weighted-average shares outstanding used for these computations.

(Weighted-average shares)	2019	2018	2017
Basic method	163,992,427	172,974,491	172,524,061
Dilutive stock options 1	820,001	1,234,274	—
Diluted method	164,812,428	174,208,765	172,524,061

¹ Due to a net loss recognized by the Company for the year ended December 31, 2017, no unvested stock awards were included in the computation of diluted earnings per share because the effect would have been antidilutive.

The following table reflects certain options to purchase shares of common stock that were outstanding during the three years ended December 31, 2019, but were not included in the computation of dilutive earnings per share because the incremental shares from the assumed conversion were antidilutive.

	2019		2018		2017
Antidilutive stock options excluded from diluted shares	2,974,401		3,942,296		4,901,269
Weighted average price of these options		$45.26		$46.77		$45.74
