Notes |
13) Stock Compensation Plans | 13) Stock Compensation Plans The Company has four fixed option plans (the “2003 Plan”, the “2006 Director Plan”, the “2013 Plan” and the “2014 Director Plan”). Compensation expense for options issued of $395,603 and $343,577 has been recognized under these plans for the years ended December 31, 2017 and 2016, respectively, and is included in personnel expenses on the consolidated statements of earnings. As of December 31, 2017, the total unrecognized compensation expense related to the options issued in December 2017 was $213,770, which is expected to be recognized over the vesting period of one year. The fair value of each option granted is estimated on the date of grant using the Black Scholes Option Pricing Model. The Company estimates the expected life of the options using the simplified method. Future volatility is estimated based upon the weighted historical volatility of the Company’s Class A common stock over a period equal to the expected life of the options. The risk-free interest rate for the expected life of the options is based upon the Federal Reserve Board’s daily interest rates in effect at the time of the grant. The following table summarizes the assumptions used in estimating the fair value of each option granted along with the weighted-average fair value of the options granted:
