We certainly have been doing our due diligence in thinking about what would happen if the U.S. were to withdraw from NAFTA, and certainly we're not looking to that kind of result. We are hoping to convince the U.S. to stay within NAFTA, but clearly, if they do choose to withdraw, we would have to evaluate domestic policy reactions on our side. We would certainly have a sense of the basis of tariffs that could be put back in place and which sectors would be affected more than others.
We have been looking primarily at a sector-by-sector approach on where the impact would be.
