Schedule of Share-based Payment Award, Restricted Stock and Restricted Stock Units, Valuation Assumptions [Table Text Block]

Grant date fair values were determined using a Monte Carlo valuation model based on assumptions as follows:



	Fiscal 2017	Fiscal 2016
Total grant date fair value	$860,000	$224,000
Total grant date fair value per share	$1.53	$0.98		-	$1.72
Expected volatility	75%	71	%	-	73%
Weighted average expected life (in years)	3 years	3 years
Risk-free interest rate	1.5%	0.9	%	-	1.0%

Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions [Table Text Block]

The fair value of each time-based vesting option award is estimated on the date of grant using the Black-Scholes option pricing model that uses assumptions noted in the following table. Expected volatilities are based on the historical volatility of the Company's stock. Expected term is calculated using the simplified method taking into consideration the option's contractual life and vesting terms. The Company uses the simplified method in estimating its expected option term because it believes that historical exercise data cannot be accurately relied upon at this time to provide a reasonable basis for estimating an expected term due to the extreme volatility of its stock price and the resulting unpredictability of its stock option exercises. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yields were not used in the fair value computations as the Company has never declared or paid dividends on its common stock and currently intends to retain earnings for use in operations.



	Fiscal 2017				Fiscal 2016
Expected volatility:	81%				82	%	-	84%
Expected term (in years):	6 years				5		-	6 years
Risk-free interest rate:	2.0	%	-	2.2%	1.4	%	-	1.7%
