Common Stock and Earnings Per Share [Abstract] |
Common Stock and Earnings Per Share | 5. Common Stock and Earnings Per Share Net income of $4,704 and $4,483 for the three months ended September 30, 2020 and 2019, respectively, and $12,888 and $11,013 for the nine months ended September 30, 2020 and 2019, respectively, is used to calculate both basic and diluted earnings per share. Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding plus potentially dilutive shares. The dilutive effect of employee stock-based compensation is included in the computation of diluted earnings per share and is calculated using the treasury stock method and expected proceeds upon exercise or issuance of the stock-based compensation. The following table summarizes the shares used in computing basic and diluted earnings per share:
