Earlier quoted context omitted.
It's where the profits are, not where the cost centers are. If the customers are in France, the profits are in France.
Are you confusing profit with revenue? The revenue is in France - easy. Profit is revenue - cost, which costs do you factor in?
Don't think so.
Profit only happens when there is revenue.
Cost is a negative influence on profit, revenue is the positive influence.
If you have zero cost, you still have profit (provided you have non-zero revenue).
If you have zero revenue, you don't have profit.
So it is obvious that the profit is where the revenue is, even though revenue ≠ profit.
