I'd like to comment about demurrage, because we don't really view that as a penalty. That, to us, is an extended asset use charge. It's like when you go to a budget car rental agency and you don't return your car on time: you're charged extra for showing up late.
The reason is that these fleets are shared amongst many shippers. If we're in a position where somebody is holding onto cars, it's a very valuable asset that has to get to somebody else. That's why those provisions are in place.
