I think we are certainly doing a lot of work to determine how quickly we can move back to as close to normal as we can get in terms of the trading relationships. I think the impact that you cited with respect to the trade going back and forth.... Those numbers are higher than the ones I have seen. I think we have been managing to maintain supply chains, by and large, particularly with the U.S. and with Mexico going forward.
I think there will probably be further pressure on us to narrow the supply chains to some degree—in other words, putting more pressure on North America as a supply chain in itself—and the relationship with the rest of the world will depend on us making efforts to maintain those supply chains as well.
I'd like to see if Eric Walsh has something further to add on this supply chain issue. He's been working on these issues more closely than I have.
