| 5. | Earnings per Share
Basic earnings per share have been computed based upon the weighted average number of common shares outstanding during each period. Diluted earnings per share include the effect of all potential common shares outstanding during each period. The shares used in the calculation of basic and diluted earnings per share are shown below:
(Dollars in thousands, except per share amounts) |  | September 30 |  | September 30 |
|  | 2016 |  | 2015 |  | 2016 |  | 2015 |
Net earnings |  | $ | 2,094 |  | $ | 2,529 |  | $ | 6,616 |  | $ | 7,922 |
Weighted average common shares outstanding - basic (1) |  |  | 3,645,618 |  |  | 3,506,440 |  |  | 3,605,509 |  |  | 3,504,487 |
Assumed exercise of stock options (1) |  |  | 69,165 |  |  | 115,397 |  |  | 67,129 |  |  | 101,674 |
Weighted average common shares outstanding - diluted (1) |  |  | 3,714,783 |  |  | 3,621,837 |  |  | 3,672,638 |  |  | 3,611,251 |
Net earnings per share (1): |  |  |  |  |  |  |  |  |  |  |  |  |
Basic |  | $ | 0.57 |  | $ | 0.72 |  | $ | 1.83 |  | $ | 2.26 |
Diluted |  | $ | 0.56 |  | $ | 0.70 |  | $ | 1.80 |  | $ | 2.19 |
(1) Share and per share values for the periods ended September 30, 2015 have been adjusted to give effect to the 5% stock dividend paid during December 2015. The diluted earnings per share computations for the three and nine months ended September 30, 2016 and 2015 include all unexercised stock options because no stock options were anti-dilutive during such periods.
