That's a great question. This is how we calculate our business and how we make our financial decisions.
We can sell an equivalent of a litre at about 85¢ to 90¢; that's a three-and-a-half-dollar gallon. That's the point at which we know we can turn a profit. Of course, the fixed cost of putting in the infrastructure comes into play, so we're going to the markets that have the highest price per litre first.
Then there are other considerations, of size and other things that the U.S. and Canada have.
