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

The fair value of each option awarded is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions noted in the following table. Expected volatilities are based on historical volatility of Common Stock. The expected life of the options granted represents the period of time from date of grant to expiration (5 years). The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant. There were no stock options granted for the year ended March 31, 2017. The per share weighted-average fair value of stock options granted for the year ended March 31, 2016 was $2.36 on the date of grant using the Black Scholes option-pricing model with the following assumptions:

	Dividend			Risk-free
	Yield			Interest rate			Volatility			Life
2016		0.0	%		1.39	%		44.54	%	5 years
