Yes, we're very much driven by what's taking place in the marketplace and internationally at a given point in time. If there are changes in that space, we obviously amend to that.
The one item I would add is when we talk about tax evasion, and our ability to detect it, which is very challenging from a technology perspective, we basically put the puzzle together to end up with that type of conclusion. The most common way, and I was speaking with my colleagues yesterday about this, we actually uncover tax evasion is our clients tell us.
