Tesla received $465
Tesla received $465 millions(not billions) of LOAN. Not a grant or subsidy. And Tesla had to pay interest on the loan, up to 3.9%.
Moreover Tesla Motors already paid $14.5 millions well ahead of the schedule(payment was done yesterday). Next payment should be done in December.
And Tesla is expected to become cash flow positive next month. They have got more then enough private investments recently to to be not cash restricted.
