Mr. John McCarthy:

I think the figure per unit is a very competitive cost per unit. There was certainly a learning attached to it and that is why we did it on a pilot basis first, in order to be able to learn. In terms of the procurement process, because much of the product that is ultimately delivered is actually manufactured off-site, one of the most significant learnings that came out of it was that being involved in the processes in the factory is every bit as important as when it actually comes onto the site and is being constructed. That was something that certainly came across very clearly in terms of major learnings from the pilot project.
