I think i buy for 100 M USD so the way it is accounted for investment would go up by 100 M USD you have an American firm making a purchase 100 M USD is going to also provide future goods and services your transportation to people it's going to be netted out because you have in net import so this it's going to do a net export on this side of it 100 M USD because it was an import negative taken from an export point of view and you have no corresponding posivitve export so you're going to have net exports net exports is going to go down 100 M USD this was A- net import of a hundred M so it makes sense that net exports will go down will be negative net export and these two once againg are going to cancel out with other so you have no net GDP which makes sense because this plane was not produced in the US.
