I would be incorrect if I said that there was not a resource implication, because that will happen at the local level. Somebody will make a local decision to let something go to zero. That doesn't mean that it was an incorrect decision, and I'm certainly not casting aspersions on those decisions, but if we have a national view, we have a better chance of managing and ensuring that there are no zero stock situations.
I'll ask Troy to jump in, as he manages the national inventory.
