FAIR VALUE MEASUREMENT [Abstract]  
FAIR VALUE MEASUREMENT
NOTE 3 – FAIR VALUE MEASUREMENT
 
The Company measures fair value and discloses fair value measurements for financial assets and liabilities. Fair value is based on the price that would be received from the sale of an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date.
 
The accounting standard establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:
 
Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
 
Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
 
Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
 
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value.
 
The fair value of the financial instruments included in the working capital of the Company is usually identical or close to their carrying value.
 
The fair value of the convertible notes derivative is based on Level 3 measurement.
 
The fair value of the remaining $5.9 million in aggregate principal amount of the Company’s outstanding 4.50% convertible promissory notes due 2018 (the “2013 Notes”), and of the remaining $58.1 million in aggregate principal amount of the Company’s outstanding 7.50% secured convertible promissory notes due 2021 (the “2016 Notes”), is approximately $5.7 million and $69.3 million, respectively, based on a Level 3 measurement. 
 
The Company prepared a valuation of the fair value of the 2013 Notes and the 2016 Notes (a Level 3 valuation) as of March 31, 2018. The values of these notes were estimated by implementing the binomial model. The liability component was valued based on the Income Approach. The following parameters were used:
