Schedule of Weighted Average Number of Shares

The following table provides a reconciliation of the weighted average number of common shares used in the calculation of basic and diluted earnings per share (in thousands):

	Year Ended December 31,
	2020	2019	2018
Weighted average common shares for basic earnings per share	237,739	237,604	237,511
Effect of dilutive securities: restricted share awards	—	—	35
Weighted average common shares for diluted earnings per share (1)	237,739	237,604	237,546

(1) For the years ended December 31, 2020 and 2019, 223 and 36, respectively, of our unvested common shares were not included in the calculation of diluted earnings per share because to do so would have been antidilutive.
