Mr. Andrew Brownlee:

No, because it is a rapidly emerging area. I do not think we have the detailed evidence. Everyone is in the same boat. Everyone is trying to work this out by the day, the week and the year. It would be good to have fixed timelines and certainty. One thing that we see again and again is that certainty is really important when we talk about infrastructure in terms of knowing how long things are going to take before we can bring them on site and build the infrastructure or the housing that is required. If we know the timeline that it is going to take to bring these new materials, we can build that into our plans, pipeline and capacity. That is the key thing. If we are going to have the capacity, we need to know when these things are happening and how long these things are going to take.
