Non-vested restricted stock awards and restricted stock units (“Restricted Stock Awards”) granted by the Company are treated as potential common shares outstanding in computing diluted earnings per share using the treasury stock method. There were no weighted average Restricted Stock Awards outstanding during the year ended December 31, 2023 that would have an anti-dilutive effect. Weighted average Restricted Stock Awards of approximately 0.1 million and 0.1 million were outstanding during the years ended December 31, 2022 and 2021, respectively, but were not included in the computation of diluted shares as the effect would be anti-dilutive or performance targets were not expected to be achieved for awards contingent upon performance.
