Common Equity And Earnings Per Share Data 7. COMMON EQUITY AND EARNINGS PER SHARE DATA

The common stock per share information is based upon the weighted average number of shares outstanding during each period. For the three and nine month periods ended September 30, 2020, the Company had an average of 18,955 and 35,564 dilutive shares outstanding, respectively. The Company had an average of 57,899 and 68,660 dilutive shares outstanding for the three and nine month periods ended September 30, 2019.

For the three and nine month periods ended September 30, 2020, there was an average of 150,783 and 81,770 potentially anti-dilutive shares outstanding, respectively, that were not included in calculating diluted earnings per share because their effect was anti-dilutive.
