Note 16 — Earnings Per Common Share

Basic and diluted earnings per common share are computed by dividing net income by the weighted-average number of basic and diluted common shares outstanding, respectively. The weighted-average number of diluted common shares includes the impact of dilutive securities, including outstanding stock options and unvested restricted stock and restricted stock units. The table below reconciles the weighted-average basic and diluted common shares outstanding for 2020, 2019 and 2018:


	Year Ended December 31,
	2020	2019	2018
	(in thousands)
Weighted average number of common shares outstanding - basic	74,696	74,362	74,002
Effect of dilutive securities 1	89	228	610
Weighted average number of common shares outstanding - diluted	74,785	74,590	74,612
