The Company recorded approximately $54,000 and $268,000 of stock-based compensation related to employee stock options for the three and six months ended June 30, 2017 and $719,000 and $1,436,000 for the three and six months ended June 30, 2016, respectively. As of June 30, 2017, there was $751,000 of unrecognized compensation cost related to outstanding options that is expected to be recognized as a component of the Company’s operating expenses over a weighted average period of 1.75 years.
The administrator of the plans determines the times when an option may become exercisable at the time of grant. Vesting periods of options granted to date have not exceeded five years. The options generally will expire, unless previously exercised, no later than ten years from the grant date. The Company is using unissued shares for all shares issued for options and restricted share awards.
The following schedule presents activity in the Company’s outstanding stock options for the six months ended June 30, 2017 (in thousands, except per share amounts):
As of June 30, 2017, options to purchase 23,051,200 shares of common stock, with an aggregate intrinsic value of $2,352,000, were outstanding that were fully vested or expected to vest with a weighted average remaining contractual term of 4.1 years. As of June 30, 2017, options to purchase 21,521,709 shares of common stock with a weighted average exercise price of $0.23 per share and a weighted average remaining contractual term of 3.6 years were fully vested with an intrinsic value of $2,306,000.
The aggregate intrinsic value of outstanding and exercisable options at June 30, 2017 was calculated based on the closing price of the Company’s common stock as reported on the OTCQB market on June 30, 2017 of $0.223 per share less the exercise price of the options. The aggregate intrinsic value is calculated based on the positive difference between the closing fair market value of the Company’s common stock and the exercise price of the underlying options.
