Just on that, my understanding of this phase-out is that it's done over 15 years, and in the first three years basically nothing happens. Then the entire 15 years are prorated, I suppose, each year, and it's done over 12 years.
So could the three-year example you're talking about happen at any time in those 12 years of phase-in, or could it also happen at some point outside or after those 15 years?
