But let me come back to the counterfactual, because it's a very good question. We did test 30 models—that is on the Department of Internal Affairs website. It has got a strong and robust analysis against the Government's bottom lines as to why we didn't end up pursuing certain models. It does give some background to those who have been interested in this approach as to why we are where we are. Can I say that the other element of the counterfactual has been to ensure that we are transparent in the way that we present this information to be able to undertake our regulatory impact analysis and our way of going forward.
