We have already shared the approach that we're using in terms of the nature of the modelling that would be done. We worked quite closely with stakeholders in understanding their issues, how they operate and what the potential implications are. We did that over the course of the last year or so. When we put out draft regulations, we always put out the draft regulatory impact analysis statement. It contains all the economic analysis as well as the costs and benefits that derive from the regulations. That will come out at the same time as the draft regulations.
