SHAREHOLDERS' DEFICIENCY [Abstract]

Schedule of Assumptions used to Estimate Fair Value of Share Options

We estimated the fair value of each option on the grant date using a Black-Scholes option-pricing model with the following weighted average assumptions:

	Three  months  Ended			Three months  Ended
	March 31,  2014			March 31,  2013
Dividend yield (1)		0.00	%		0.00	%
Expected volatility (2)		118.5	%		99.2% - 100.3	%
Risk-free interest rates (3)		1.72	%		0.63	%
Expected lives (2)		5.0 YEARS			2.0-4.0 YEARS

(1)	We have not paid cash dividends on our common stock since 1981, and currently do not have plans to pay or declare cash dividends. Consequently, we used an expected dividend rate of zero for the valuations.
(2)	Estimated based on our historical experience. Volatility was based on historical experience over a period equivalent to the expected life in years.
(3)	Based on the U.S. Treasury constant maturity interest rate with a term consistent with the expected life of the options granted.
