Why couldn't the manufacturer take some of the profit (65%) for there part?
Why not. That is how it has been working in the past. BBDA shareholders fund everything and BW collects the profit and spends it on himself and racing.
good example. BBDA SH 100% funded the EU deal. SHs get 5%, BW get 70% and the dude he is working with gets 25%. BW is such a great deal maker.
