Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS

In accordance with ASC 820 (Fair Value Measurements and Disclosures), the Company uses various inputs to measure the outstanding warrants on a recurring basis to determine the fair value of the liability. ASC 820 also establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:

 

Level 1 - Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date

 

Level 2 - Quoted prices in markets that are not active or inputs which are either directly or indirectly observable

 

Level 3 - Unobservable inputs for the instrument requiring the development of assumptions by the Company

 

The following table classifies the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy as of December 31, 2020 and 2019 (amount in thousands):

 

    Fair Value at December 31, 2020              
    Total     Level 1     Level 2     Level 3  
Liabilities:                        
Derivative liability - Warrants     4,444       -       -       4,444  
Total liabilities   $ 4,444     $ -     $ -     $ 4,444  

 

    Fair Value at December 31, 2019              
    Total     Level 1     Level 2     Level 3  
Liabilities:                        
Derivative liability - Warrants     4,144       -       -       4,144  
Total liabilities   $ 4,144     $ -     $ -     $ 4,144  

 

There were no transfers between Level 1, 2 or 3 during the years ended December 31, 2020 and 2019.

 

The following table presents changes in Level 3 liabilities measured at fair value for the year ended December 31, 2020 and 2019. Both observable and unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category. Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long- dated volatilities) inputs (amount in thousands).   

 

    Derivative liability - Warrants  
Balance at January 1, 2019   $ -  
Addition     7,762  
Change in fair value     (3,618 )
Balance at December 31, 2019     4,144  
Change in fair value     300  
Balance at December 31, 2020   $ 4,444  

 

A summary of the weighted average (in aggregate) significant unobservable inputs (Level 3 inputs) used in the Monte Carlo simulation measuring the Company’s derivative liabilities that are categorized within Level 3 of the fair value hierarchy as of December 31, 2020 and 2019 is as follows:

 

    December 31,     December 31,  
    2020     2019  
Exercise price   $ 0.0044     $ 0.0044  
Contractual term (years)     3.32       4.32  
Volatility (annual)     75.0 %     70.0 %
Risk-free rate     0.2 %     1.7 %
Dividend yield (per share)     0 %     0 %
