Yes, most of these contracts r win-wins for the cost savings, economies of scale, IP, variable cost not fixed and speed to market. Not even BHP/ BLT, RIO and GLEN can beat it as they insource at a higher cost for these sorts to execute their knock-all others down strategy with IOP.
It is sad IMHO that BHP/BLT and RIO have embarked on their present strategies without the likes of DOW and ofcourse adversely affecting FMG. Quite perverse but nothing anyone can do about it. It's a licence to make money holding an oligopolistic position in IOP, quite sad, unfortunate but true.
FMG, AGO and the like can only really beat it by using DOW, trying to reduce costs to compete for distributing to the steel mills coping with two players in the ultimate competition of driving IOP to the bottom only to reap windfall gains on the way up when MGX and others go to the wall as they r doing.
