For example, to use the case of VIA, which is our largest passenger customer, they pay us basically a trackage right fee to operate on our railroad, which we negotiate with them. There is a target percentage on-time performance in the contract. If we go above that, they pay us a little bit more money. If we fall below that we have to rebate some of the money to them, so it's money out of our pocket.
