STOCK-BASED COMPENSATION | The Company has two equity incentive compensation plans: a 2004 Stock Option Plan and a 2006 Stock Incentive Plan. 2004 Stock Option Plan – The 2004 Stock Option Plan authorized the issuance of incentive stock options (“ISOs”) and non-qualified stock options (“NQOs”) to the Company’s officers, directors or key employees or to consultants that do business with the Company for up to an aggregate of 23,810 shares of common stock. On September 7, 2006, the Company terminated the 2004 Stock Option Plan, except to the extent of issued and outstanding options then existing under the plan. The Company had options outstanding to purchase 762 shares of common stock under its 2004 Stock Option Plan at December 31, 2014. These options expired unexercised in 2015. 2006 Stock Incentive Plan – The 2006 Stock Incentive Plan authorizes the issuance of ISOs, NQOs, restricted stock, restricted stock units, stock appreciation rights, direct stock issuances and other stock-based awards to the Company’s officers, directors or key employees or to consultants that do business with the Company for up to an aggregate of 1,715,000 shares of common stock. Stock Options – On June 18, 2013, the Company granted options to purchase an aggregate of 229,000 shares of the Company’s common stock at an exercise price of $3.74 per share, which was the closing price per share of the Company’s common stock on the date of grant, with an estimated fair value of $1.68. The options vested as to 33% on each of April 1, 2014 and April 1, 2015 and vest as to 34% on April 1, 2016. The options expire 10 years from the date of grant. Fair value was determined using the Black-Scholes Option Pricing Model. The inputs to estimating fair value were: exercise price of $3.74; estimated life of 3.0 years; expected volatility of 68.0%, risk free interest rate of 0.57% and no dividend yield. The Company estimated expected volatility using peer companies within its industry.
