Earnings Per Share [Text Block] | Note 11. Earnings per Common Share Basic earnings per common share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The following table presents the computation of basic and diluted earnings per share for the three and six months ended June 30, 2021 and 2020 (dollars in thousands, except per share data):
|  | Three Months Ended |  |  | Six Months Ended |
|  | June 30, 2021 |  |  | June 30, 2020 |  |  | June 30, 2021 |  |  | June 30, 2020 |

Net income |  | $ | 3,342 |  |  | $ | 2,243 |  |  | $ | 5,778 |  |  | $ | 3,948 |
(Denominator): |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Weighted average shares outstanding – basic |  |  | 4,868,901 |  |  |  | 4,849,719 |  |  |  | 4,866,376 |  |  |  | 4,900,303 |
Potentially dilutive common shares – restricted stock units |  |  | 4,385 |  |  |  | — |  |  |  | 6,330 |  |  |  | 2,542 |
Weighted average shares outstanding – diluted |  |  | 4,873,286 |  |  |  | 4,849,719 |  |  |  | 4,872,706 |  |  |  | 4,902,845 |
Income per common share |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Basic |  | $ | 0.69 |  |  | $ | 0.46 |  |  | $ | 1.19 |  |  | $ | 0.81 |
Diluted |  | $ | 0.69 |  |  | $ | 0.46 |  |  | $ | 1.19 |  |  | $ | 0.81 |
Restricted stock units for 15,858 shares of common stock were not considered in computing diluted earnings per share for the three months ended June 30, 2020 because they were antidilutive. There were no antidilutive shares of common stock for three months ended June 30, 2021 and the six months ended June 30, 2021 and 2020.
