The balance sheet values the warrants at $0 because the Company takes a most conservative approach (as well it should)
However, if the Company decided to sell the Warrants, there would be a buyer at this time.
It's hard to say what price the Company would realize for just the Warrants. And I won't speculate on this Board. But it would absolutely NOT be $0
If VTGN were to be successful in the future (and for the sake of arguments, go to $4 someday), then the Warrants would bolster the balance sheet and enable the Company to sell the shares without feeling that all the potential future upside (subsequent to that point in time) were to be forfeited.
Also, Im not sure that its prudent to comment on every single daily close of VTGN. I believe that the Company didn't make that $480,000 investment in order to sell the stock at $1.55 or to boast about potential interpretations of Warrant Value.
Let's be patient and see what happens over next 6 months and beyond
