Per Share Amounts

3 Months Ended

Mar. 31, 2021

Per share information has been computed based on the weighted average number of common shares and dilutive common share equivalents outstanding. The computation for the three-month periods ended March 31, 2021 and 2020 excluded approximately 370,000 and 430,000, respectively, of the Company's stock options because the exercise price of the options was higher than the average market price during those periods.

On March 31, 2020, the Company’s Award Agreements (as defined below) expired and the unvested performance share awards were returned to the Company’s stock incentive plan - see Note 7 for further discussion. Based on the guidance provided in accordance with ASC 260 Earnings Per Share (“ASC 260”), the weighted average common shares for basic earnings per share, for the three-month period ended March 31, 2020, excluded the weighted average impact of the unvested performance share awards. These awards were legally outstanding but not deemed participating securities and therefore were excluded from the calculation of basic earnings per share. The unvested shares were also excluded from the denominator for diluted earnings per share because they were considered contingent shares not deemed probable as of March 31, 2020.

The following table sets forth the computation of basic and diluted earnings per share for the three-month periods ended March 31, 2021 and 2020:
