A couple of months ago, I questioned the reason for the PP, and received a lot of negative comments.   This management made a big choice and changed direction from research to production by buying DensLight and BBP.   At the time, Suresh said "we're a real company now".   Unfortunately, it took a lot of money to renovate DenseLight, .... more than we had. 

A company like PTK can't go to the bank for money.   Even if they could, why would they, because that money has to be paid back.  Far easier to do a PP.   The money received from shareholders never has to be paid back.   No guarantees, no obligations.   And you don't even have to thank the shareholders.

 "Another PP , borrowing from Bankers, Or closing the company?"

I'm not happy that due to management decisions, such a question even has to be asked!
