That was for the previous study. We're going to be redoing all of it.
At this point we haven't discussed yet with consultants what discount rates to use. It's usually an average of what the provinces use and what the federal government uses. Treasury Board has a discount rate that it uses, but each of the provinces tends to use something different. We'll probably look at what market discount rate would be suggested in terms of a project of probably a 30-year lifespan or so and then try to normalize that with what the treasury boards of the three governments would impose.
