(14) Stock Compensation Plans

The Company has one stock option plan. Under the 2016 Stock Incentive Plan (the "Plan"), the Company may grant option grants, stock appreciation rights, restricted stock, or stock units to an employee for an amount up to 25,000 total shares in any calendar year. With respect to awards granted to non-employee directors under the Plan during the term of the Plan, the total number of shares of common stock which may be issued upon exercise or settlement of such awards is 100,000 shares and no outside director may receive option grants, stock appreciation rights, restricted stock or stock units for more than 3,000 shares total in any calendar year. There are 735,555 shares authorized under the 2016 Stock Incentive Plan. The total number of shares authorized has been adjusted to give retroactive effect to stock dividends and stock splits, including the 5% stock dividend declared on January 24, 2019, payable March 29, 2019 to shareholders of record as of February 28, 2019. The 2016 Stock Incentive Plan will terminate on March 15, 2026.

The Compensation Committee of the Board of Directors is authorized to prescribe the terms and conditions of each option, including exercise price, vestings, or duration of the option. Generally, option grants vest at a rate of 25% per year after the first anniversary of the date of grant and restricted stock awards vest at a rate of 100% after four years. Options expire 10 years after the date of grant. Options are granted with an exercise price of the fair value of the related common stock on the date of grant.

The Company determines fair value at grant date using the Black-Scholes-Merton pricing model that takes into account the stock price at the grant date, the exercise price, the risk-free interest rate, the volatility of the underlying stock and the expected life of the option.

The weighted average assumptions used in the pricing model are noted in the following table. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected volatility is based on both the implied volatilities from the traded option on the Company’s stock and historical volatility on the Company’s stock.

The Company expenses the fair value of the option on a straight line basis over the vesting period. The Company estimates forfeitures and only recognizes expense for those shares that actually vest.

The following table shows our weighted average assumptions used in valuing stock options granted for the years ended December 31:

	2018		2017		2016
Risk-Free Interest Rate		2.57%		1.89%		1.23%

Expected Dividend Yield		0.00%		0.00%		0.00%

Expected Life in Years		5.00		5.00		5.00

Expected Price Volatility		14.44%		22.88%		28.41%

In addition to stock options, the Company also grants restricted stock awards to directors, certain officers and employees. The restricted shares awarded become fully vested after one to four years of continued employment or service from the date of grant. Restricted shares are forfeited if officers and employees terminate prior to the lapsing of restrictions.

Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan ("ESPP"). Under the 2016 ESPP, the Company is authorized to issue to an eligible employee shares of common stock. There are 295,277 shares authorized under the 2016 ESPP, which include authorized but unissued shares under the 2006 Amended ESPP. The total number of shares authorized has been adjusted to give retroactive effect to stock dividends and stock splits, including the 5% stock dividend declared on January 24, 2019, payable March 29, 2019 to shareholders of record as of February 28, 2019. The 2016 ESPP will expire on March 16, 2026.

The ESPP is implemented by participation periods of not more than twenty-seven months each. The Board of Directors determines the commencement date and duration of each participation period. An eligible employee is one who has been continually employed for at least ninety (90) days prior to commencement of a participation period. Under the terms of the Plan, employees can choose to have up to 10 percent of their compensation withheld to purchase the Company’s common stock each participation period. The purchase price of the stock is 85 percent of the lower of the fair value on the last trading day before the Date of Participation or the fair value on the last trading day during the participation period. Approximately 30 percent of eligible employees are participating in the Plan in the current participation period, which began November 24, 2018 and will end November 23, 2019.

Under the Plan, at the annual stock purchase date of November 24, 2018, there were $90 in contributions, and 8,863 shares were purchased at an average price of $10.20. The total number of shares purchased and average price have been adjusted to give retroactive effect to the 5% stock dividend declared on January 24, 2019, payable March 29, 2019 to shareholders of record as of February 28, 2019. For the year ended December 31, 2018, 2017, and 2016, there was $22, $56, and $24, respectively, of recognized compensation related to ESPP issuances. Compensation cost is reported in salaries and employee benefits expense in the consolidated statements of income.
