I think one of the points we make is that it's not a question of having the lowest taxes. We're not doing a race to the bottom. What we're looking for are tax rates that are competitive with those jurisdictions that we do business with, that we compete with. So we think setting targets for where we might want to have both business and personal tax rates would be an appropriate thing to do. We're not advocating a particular level; we're just saying take a look at where other jurisdictions are, and we want to have the most competitive tax picture in the window.
