Many of our distinguished legislators are questioning why a trading company has the barest capital to transact billions with the govt.   Its a trading company that is why and relies on credit and trust of its suppliers.   It is contingent upon shipping companies, factories and airlines to have huge equity   
But not for a trading company.   We ran a supermarket before  and we were running at 90% debt to equity  The suppliers whose sales manager were the old school network trusted us with their merchandise on credit
A hardware company with chain of stores I learned had most of their goods on consignment   
There seems to be nothing wrong with the little trading company capitalized only a small fraction of the total deal   Especially if they are friends of the suppliers,
