In terms of what we expect might happen, we've had many claims brought against Canada, for example, under NAFTA. The Dow is the most recent. It ended up being resolved.
On the other hand, we have a good precedent in a case called Methanex, where the arbitral panel ruled against the applicant and said that this kind of regulation is not expropriation. The problem is that it's not binding on any of the subsequent arbitral panels. It says, right in this agreement, that it's case by case. The issues about reasonability, legitimacy, good faith, etc., would be up for argument every time.
