Maybe just to build a little bit on that and on some of my comments earlier, they really are two very different initiatives. The TPP, frankly, is much larger and builds new trade rules, including those between partners that don't already have free trade agreements with each other. It's a much bigger grouping, and it's a much more ambitious grouping than is the Pacific Alliance. The Pacific Alliance involves these four countries that already have free trade agreements with one another, and they want to harmonize and build on that platform from there, so they have very different objectives.
With respect to being involved in one or the other, frankly, they're just two different initiatives, and the department, as you know from this and other briefings, is already engaged in many trade negotiations with different individual partners and groups of partners, so I don't see a conflict in that.
