5) Stock-based Compensation

5) 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 $58,053 and $101,316 has been recognized for these plans for the three months ended June 30, 2018 and 2017, respectively, and $116,140 and $203,312 has been recognized for these plans for the six months ended June 30, 2018 and 2017, respectively. As of June 30, 2018, the total unrecognized compensation expense related to the options issued was $97,605, 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.

A summary of the status of the Company’s stock compensation plans as of June 30, 2018, and the changes during the six months ended June 30, 2018, are presented below:
