Just very quickly, as I understand it the Gift Aid system has some complexities in terms of its incentives. It doesn't always incentivize the behaviours that they were expecting. There's some complexity in how it's delivered, and it's also delivered under a one-government system; there are no provincial jurisdiction, etc. I don't know a lot more about it. I just know it has created complications for both charities and the government in terms of administration.
In terms of tax incentives in other countries, Canada is one of the world leaders and there are not a lot of others with models that I think.... We've looked at the U.S., and at the U.K. We stand out in terms of our capacity to understand and incentivize giving around the world.
