The second point, although it wasn't your question, I will say that I think it should be emphasized that there's a difference here between what the U.S. does in terms of its tax base, including taxation of citizens, and what the intergovernmental agreement does. We don't tax citizens. Perhaps no other country apart from the U.S. does tax on a citizenship basis. In our view at least to a lot of issues, that's clear, but as to whether or not they're entitled to enforce their laws, we've kind of accepted since probably our first tax treaty with them in the 1940s that they can, and this is part of that.
By virtue of my preamble, I've lost your question, sir. I'm sorry.
