emptyone "it appears they are more or less a trading company now." This is extremely far from the truth. The contribution trading makes to the bottom line is way less than 10% I think. A credit line of 10 million dollars will not change that dramatically. Looking a few years into the future it is true that the credit line may lead to much higher credits. This is just a possibility and nothing that is assured. Read Solomon's detailed account of this a few times! In the past everything has not moved according to best-case scenarios. It is not obvious that this will also turn out to be the case as far as trading is concerned.
