For those who have margin arrangements with their institution most allow 70% borrowing power on stocks that trade over the $2.00 price level.
So if you exercised 100,000 warrants at .35 or $35,000 and deposited the shares into your account you would have 100,000 PTK shares at $2.50 or $250,000 in your account.
You would be allowed $175,000 in margin (borrowing power) based on 70% of $250,000 and pay interest at prime plus a small increment.
So in other words for $35,000 in outlay you can leverage an additional $140,000 in investment capital.You can withdraw the funds if you want as they are secured by the shares.
So if you had 500,000 or 1 million or more............
You still have the shares and the power of leverage with you...... and POET has the cash---------win, win
