Thank you for the question.
The answer is yes. I think the question you're asking, though, is whether others have had sufficient opportunity to consider its implications, and we believe the answer to that is yes as well.
I would make the point that, yes, the agreement was signed on February 5 of this year, so a couple of months ago, but our intention to negotiate such an agreement was announced in November of 2012. In this case, it's a negotiation based on a model agreement, which the U.S. had in the public domain. That, together with the release of draft legislation, the implementing legislation that's before you today in draft form with some revisions as a result of consultations, was also released later on the same day we signed the agreement, so that also enables opportunity for discussion and comment.
