Again, it is very difficult to come up with a number on this, and I'll give you an example of why.
We're starting off with a period of some eight years ago, with the lead-up to the 1999 budget. The government was seeing a problem becoming prevalent in those days. These measures put an end to that and curtailed that kind of activity. Where would it have gone if these measures had not been introduced? That's anybody's guess. While one can well imagine how innovative tax schemes are developed for clients who can afford very high-priced tax counsel, you were seeing back in those days that tax savings mechanisms were being marketed basically to the masses. Where that would have gone had the government not proposed changes back then and proceeded over the course of the years, that's a very good question. I can't give you a number on that.
Wally, perhaps you could give them some ballpark estimation of how these measures have curtailed the kinds of activities we were seeing back in 1999.
