The risk-free rate is based on the U.S. Treasury yield curve in effect at the date of grant for the expected term of the option. The Company has a stock option plan approved in May 2004, amended in June 2008 and again in August 2009 (the “2004 Plan”), for directors and key employees under which 2,500,000 shares of common stock could have been issued. No other shares can be issued from the 2004 Plan, and approximately 1,624,000 options are outstanding as of September 30, 2015.

Approximately 1,018,000 options are outstanding as of September 30, 2015. Unless otherwise stated in the stock option agreement, options are 20% vested on the date of grant, with the balance vesting 20% per year over the next four years, except for directors whose options vest six months from the date of grant. Options were granted in 2015 only from the 2010 Plan at the market value of the stock at date of grant, as defined in the plan. The Company grants stock options to its directors as compensation for services performed. All of the options granted are for a period of ten years from the date of issuance, are pursuant to the 2010 Plan, and vest six (6) months from the issuance date.

These options are exercisable at prices ranging from $0.76 to $2.28. To reflect the value of the stock options granted, the Company records a non-cash charge to earnings totaling $254,500 over the requisite vesting period in selling, general and administrative expense. For the nine and three months ended September 30, 2015, the Company recorded an expense of approximately $98,300 and $30,800, respectively.
