And, lastly, the amalgamation in terms of the benefit modelling that's being quoted refers to the fact that the amalgamation of these entities will achieve a 50 percent capital expenditure efficiency improvement and that will be delivered through the consolidation of water networks in order to achieve that benefit. That assumption is fundamental and significant in terms of the underlying benefit case for this proposed reform and I want to understand, Minister, in terms of: how did you came to that number of 50 percent? What were the considerations in regards to other mechanisms in which you could achieve benefit and did you actually consider other counterfactuals around that, and, in terms of deriving that capital efficiency benefit, what other considerations did you put thought to?
