It does. It also sets expectations of our partners.
But we do change; we do change provisions. We do try to build on what we've learned in the past, and we do try to move issues forward. For example, we have a lot of new obligations in the TPP with respect to competition as it relates to state-owned enterprises. We haven't had that before, but based on experience in the trading environment for our companies and based on the feedback we have, we felt that this was something that would be important.
Even though we have precedents from the past in some of these areas, we do try, and I think it's very much our responsibility, to improve on those and move them forward in different ways, based on experience and feedback.
