Again I'll be brief. Very quickly, regarding the methodology, we've calculated what we call a delay factor based on changes from planned start and end dates to reported start and end dates. We've outlined the methodology in excruciating detail on page 12, so I won't step you through it. Effectively, we took two different approaches to come up with a base case and worst case.
The concerns that Infrastructure Canada had were fourfold. One was that projects that hadn't started had no obligation to report, so why were we using information to that degree? We noted that many projects that hadn't started had also reported, so that's fine.
Secondly, on the Quebec projects, something we weren't aware of at the time but understood at the meeting was that, under the PRECO agreement, projects did not have to report or submit claims until the program was finished, and the proviso was that the projects had to be terminated by December 31, 2010, as opposed to March 31, 2011.
The third issue that was brought up involved our worst-case scenario and some of the assumptions we made for using certain start and end dates versus others in the database. We agreed that when we got a new set of data we would maybe run a fourth scenario somewhere in the middle to see what came up. I'm not sure it's going to make a big difference.
