The following outlines the significant weighted average assumptions used to estimate the fair value information presented, with respect to warrants utilizing the Binomial Lattice option pricing models at, and during the six months ended September 30, 2016:

 

Risk free interest rate     0.79% – 1.38%    
Average expected life     3 months – 2.33 years  
Expected volatility     65.9% – 111.1%  
Expected dividends     None  

 

The expected volatility was based on the historic volatility. The expected life of options granted was based on the "simplified method" as described in the SEC's guidance due to changes in the vesting terms and contractual life of current option grants compared to our historical grants.

 

Based on the above assumptions, we valued the warrants that were exchanged for common stock (see Note 6) during the six months ended September 30, 2017 at $130,214.
