Notes to Financial Statements

11. Stock options

At the Company's 2006 Annual Meeting of Stockholders, the stockholders approved the 2006 Stock Incentive Plan (the "Plan").  The Plan permits the issuance of stock options, restricted stock awards, and performance shares to employees, officers, directors, and consultants of the Company.  Initially, and until such time as the Board creates a Compensation Committee, the Board of Directors will administer the Plan.  The total number of shares of common stock that may be issued pursuant to awards under the Plan is 5,000,000.  Under the Plan, no participant may receive awards of stock options that cover, in the aggregate, more than 500,000 shares of common stock in any fiscal year.   Under the terms of the Plan, no additional options could be granted after the tenth anniversary of the Plan, which occurred on June 5, 2016.

The Company expenses the cost of options granted over the vesting period of the option based on the grant-date fair value of the award.  Option fair values are estimated at the grant date using the Black-Scholes option valuation model.  The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable.  For purposes of determining the expected life of the options, the Company utilizes the Simplified Method as defined in Staff Accounting Bulletin No. 107 issued by the Securities and Exchange Commission.  In addition, the Black-Scholes option valuation model requires the input of other highly subjective assumptions including stock price volatility.

A summary of the Company's Incentive Plan as of December 31, 2018 and changes during the year is presented below:
