Share-based Payment Arrangement [Abstract]

(17) Stock Compensation Plan

The Company has a stock-based employee compensation plan which allows for the issuance of stock options and restricted common stock, the purpose of which is to provide additional incentive to certain officers, directors, and key employees by facilitating their purchase of a stock interest in the Company. Compensation expense related to prior awards is recognized on a straight line basis over the vesting period, which is typically four or five years. The stock-based compensation cost related to these awards was $286,000, $223,000 and $172,000 for the years ended December 31, 2019, 2018 and 2017, respectively. The Company recognized tax benefits of $71,000, $194,000, and $180,000 for the years ended December 31, 2019, 2018 and 2017, respectively.

For stock options, the exercise price may not be less than 100% of the fair market value of the shares on the date of the grant, and no option shall be exercisable after the expiration of ten years from the grant date. In determining compensation cost, the Black-Scholes option-pricing model is used to estimate the fair value of options on date of grant. The Black-Scholes model is a closed-end model that uses the assumptions outlined below. Expected volatility is based on historical volatility of the Company’s stock. The Company uses historical exercise behavior and other qualitative factors to estimate the expected term of the options, which represents the period of time that the options granted are expected to be outstanding. The risk-free rate for the expected term is based on U.S. Treasury rates in effect at the time of grant.

On May 20, 2015, our stockholders approved the 2015 Stock Incentive Plan which authorized the issuance of equity awards covering 319,070 shares of common stock as adjusted for subsequent stock dividends. On August 1, 2017, the Compensation Committee awarded 3,167, as adjusted for subsequent stock dividends, shares of restricted common stock and options to acquire 37,545, as adjusted for subsequent stock dividends, shares of common stock. The restricted stock awards vest ratably over one year and the value was based on a stock price of $25.27 per share on the date such shares were granted as adjusted for subsequent stock dividends. The options vest ratably over four years. On August 1, 2018, the Compensation Committee awarded 11,885, as adjusted for subsequent stock dividends, shares of restricted common stock. The value of the 11,885, as adjusted for subsequent stock dividends, shares was based on a stock price of $26.31 on the date such shares were granted as adjusted for subsequent stock dividends. On August 1, 2019, the Compensation Committee awarded 3,587, as adjusted for subsequent stock dividends, shares of restricted common stock and options to acquire 67,631, as adjusted for subsequent stock dividends, shares of common stock. The restricted stock awards vest ratably over one year and the value was based on a stock price of $22.32 per share on the date such shares were granted as adjusted for subsequent stock dividends. The options vest ratably over four years. The fair value of the options granted were determined using the following weighted-average assumptions as of the grant date:
