Not all losses are cash losses, that is depreciation and amortization doesn't deplete cash but IS an expense for tax purposes. Other techs have huge losses, but only a small part of those expenses actually eat cash. Meanwhile, COSN trades at JUST HALF of BOOK VALUE!
Any accountant will tell you it works the other way to. e.g they pay say $200k to the thier manufacture and partner for a box and it sits on trial somewhere (like two years in the case of NTT). This is a real cash cost as they pay thier supplier. But it sits in the books as an asset for the full price whereas in reality its practically worthless. When and if the customer signs he gets the latest box - the 9500- then the 9000 trial box is scrap.
I think all these trials without closure are killing them.
