Maybe I could ask you something just before we turn it over to Bernard.
You said that the life cycle is 35 to 40 years, but what has been the average for these P3s? My sense, coming from a construction background, is that there's not a great deal of maintenance in the first 20 years of a brand new building. There's not even a lot in the first 30 years.
Let me ask the Edmonton school board this question: what is the length of time for your P3s on these schools?
