The Company maintained an Amended and Restated 2004 Equity Plan (the “2004 Plan”) for directors, officers, and key employees. The 2004 Plan was terminated on May 23, 2013. The Company’s shareholders approved the 2013 Equity Incentive Plan (the “2013 Plan”). The equity plans provide for the grant of incentive and nonqualified stock options and restricted stock. The equity plans provide that the option price for both incentive and nonqualified stock options will be determined by the Board of Directors at no less than the fair value at the date of grant. Options granted vest on a schedule determined by the Board of Directors at the time of grant. Generally options vest over four years. All options expire no later than ten years from the date of grant. Restricted stock is subject to time vesting. The 2013 Plan will terminate at the 2023 Annual Shareholders Meeting to be held May 25, 2023. The Company intends to propose a new 2023 Equity Incentive Plan at the 2023 Annual Shareholders Meeting. All equity awards outstanding under the 2013 Plan remain outstanding subject to the terms of the respective award agreement. In 2022, the Company granted 387,000 shares of nonqualified stock options and 238,811 shares of restricted stock subject to time vesting requirements. There were 1,475,594 shares available for the issuance of equity awards under the 2013 Plan as of December 31, 2022.

As of December 31, 2022, there was $1,294,000 of total unrecognized compensation cost related to nonvested stock options granted under the equity plans. That cost is expected to be recognized over a weighted-average period of approximately 2.66 years.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table, including the weighted average assumptions for the option grants in each year.

(1)	The expected life of employee stock options represents the weighted average period the stock options are expected to remain outstanding based on historical experience. Volatility is based on the historical volatility of the stock price over the same period of the expected life of the option.

(2)	Based on the U.S. Treasury constant maturity interest rate with a term consistent with the expected life of the option granted.

(3)	Each grant’s dividend yield is calculated by annualizing the most recent quarterly cash dividend and dividing that amount by the market price of the Company’s common stock as of the grant date

The Company estimates the impact of forfeitures based on historical experience. Should the Company’s current estimate change, additional expense could be recognized or reversed in future periods. The Company issues authorized shares of common stock to satisfy stock option exercises.
