Stock awards under the Company's stock option plans have been granted with exercise prices that are no less than the market value of the stock on the date of the grant. Options granted under the plans are generally time-based or performance-based options and vesting varies accordingly. Options under the plans expire up to a maximum of ten years from the date of grant.

The fair value of each option award granted during the period is estimated on the date of grant using the Black-Scholes option valuation model and assumptions as noted in the following table:

	Years Ended December 31,
	2016	2015
Risk-free interest rate	1.51 – 2.18%	1.80 - 1.90%
Volatility	50.00%	50.00 - 85.68%
Expected dividend yield	0%	0%
Expected life	6.5 years	6.5 years
Estimated forfeiture rate	0%	0%

The expected life of the options is based on the observed and expected time to full-vesting, forfeiture and exercise. Groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The risk-free rate is based on rates provided by the U.S. Treasury with a term equal to the expected life of the option. The Company has never paid dividends and does not currently anticipate paying any in the foreseeable future.

During December 2015 the Company changed its method of calculating expected volatility that is used in its fair value measurements and measurements of share based compensation cost. The new method estimates expected volatility by using a combination of the Company's historical volatility since June 22, 2015, the acquisition date of the XTRAC and VTRAC businesses, plus the historical volatility of stocks of similar publicly-traded companies for a period matching the expected term of the underlying instrument. The Company believes that this method provides for a better estimate of future volatility because of the significant change to the overall Company resulting from the acquisition of the XTRAC and VTRAC businesses on June 22, 2015. The Company had historically calculated expected volatility based solely upon the historical volatility of the Company's daily closing stock price.

On December 6, 2016, the Company granted an aggregate of 450,000 options to purchase common stock to the non-employee board directors with a strike price of $0.55. The options vest over a one year period and expire ten years from the date of grant. The aggregate fair value of the options granted was $182.

On October 31, 2016, the Company issued 542,500 options to purchase common stock to its' Chief Executive Officer with a strike price of $0.55. The options vest over three years and expire ten years from the date of grant. The aggregate fair value of the options granted was $150. Additionally, the Company issued 1,007,500 options to purchase common stock to its' Chief Executive Officer with a strike price of $0.55. These options vest based on performance goals determined by the board of directors for each of the years 2017 through 2019.

On June 7, 2016, the Company granted an aggregate of 340,000 options to purchase common stock to a number of employees with a strike price of $0.75. The options vest over four years and expire ten years from the date of grant. The aggregate fair value of the options granted was $128.

Stock-based compensation expense, primarily included in general and administration, for the years ended December 31, 2016 and 2015 was $113 and $1,753, respectively. As of December 31, 2016 there was $371 in unrecognized compensation expense, which will be recognized over a weighted average period of 1.3 years.
