Absolutely, and I will probably ask Philippe Le Goff to add in, since he was responsible for the detailed work.
In general, what I could offer up is that they have a lot of business intelligence information at the Canada Revenue Agency that they can use in so many ways. We felt that there were some opportunities where they could have used that to target audits for suspicious activity they might have seen or for applications that alerted them. They chose to just look at post-payment controls.
I don't know, Philippe, if you wanted to add something a little more specific, perhaps.
