On the last issue, perhaps I'll put this as a challenging question. If you want to comment on any of the others, you can, but you mentioned the perfect storm. I think Mr. Dolan said this industry has become a leader in productivity in spite of all these conditions. Yet some people in your sector have hinted to me that perhaps it's because of all these challenging conditions that productivity has increased so much. Did all of these conditions actually cause the rise in productivity in your sector, or was it actually in spite of all these conditions?
If you want to comment on any of those, or if you want to provide further information, I'd allow you to do so, or you can make some final wrap-up comments here.
