Obviously, changes in the law need to be made by Parliament, and they need to be introduced by the government. That's a decision that ultimately needs to be made. I would say that the work that's ongoing and the work we're doing with the international community is to ensure that we understand the best way to ensure proper collection of the tax.
What we've heard in our consultation and in the work with the OECD is that companies want to comply with their tax obligations, but at the same time, they're doing business in a lot of countries. They want to make sure, then, that the regime that's in place is as easy to comply with as possible. The experience of other countries that we're gathering to see what works and what doesn't work is certainly helping us in providing the best advice we can to the government of the day.
