| 6. | Earnings Per Common Share
Basic earnings per share include only the weighted average common shares outstanding. Diluted earnings per share include the weighted average common shares outstanding and any potentially dilutive common stock equivalent shares in the calculation. Treasury shares are excluded for earnings per share purposes. For the three and nine month periods ending September 30, 2017, options to purchase 10,000 common shares, with an exercise price of  $4.00, were outstanding but were not included in the computation of diluted earnings per common share because to do so would be antidilutive.
