We do a careful analysis with the aid of the Department of Justice of all such trade-related issues. We would know going into developing any amendments, and we know from having implemented the Energy Efficiency Act these many years, that we have no issues on that score. In other words, it doesn't come up and surprise us that we introduce a difficulty with NAFTA and so forth. There are very real reasons behind our regulating for energy efficiency, and we don't experience challenges.
