It leads to a rather difficult point in the Government's books, or at least it did, which is this. A commercial valuation: how much would a person pay to buy the stream of value produced by KiwiRail—that is, a billion bucks. About a billion dollars—that's all someone would pay to own KiwiRail. Then, if you wanted to replace KiwiRail—if you wanted to rebuild the tracks and replace the rolling stock and do all the things that KiwiRail has—that would cost $6.3 billion.
