Again, I apologize for not having a slide on this.
They have been making investments in plant and equipment in that sector. It is a very impressive number. I don't have the specific number in my hands here, but there is a correlation between the investment they have made in technology, plant and equipment, and their resultant productivity.
We can take the example that I used earlier, the everyday example of grocery shopping and checking out your groceries yourself using the scanner technology and investment. I think one could take each of these sub-sectors and find examples of where the investment has been able to result in that increase in labour productivity.
