Yes, so on the Qdoba tests, there's not a whole lot to report yet because we've only built a very small handful of mid single digits, and these things are literally just a few weeks old. So it's pretty early. We have some that are performing gangbusters well, and we're happy to see that. We have others that are performing above what we would see from a new opening but not at the high side of the range of the complete set of locations that we're testing. So overall, confidence is really high, but it would be too soon for me to give you a read on that with any type of accuracy. We really need to see, after the buzz of the new store opening dies down, what these AUVs are. We have learned a lot about the design elements, the cost of the design, also the practicality of the design, and our construction team is actually making changes on the fly. For example, some of the exterior trade dress, the various construction managers that have worked on these projects figured out how to create the exact same look and feel that we were going for but to do it significantly cheaper. So we had to go in and speak to some of the municipalities about the permitting, and that slowed down a few of the sites that were supposed to open in Q4, but we'll be able to build those elements into the trade dress in Q1 in a cheaper and more efficient manner. So we're learning a lot about that process. We'll know more about the returns as time goes on. And the way we're approaching this, to your point, where we sort of test in this exhaustive way, one of the things that we have done in the past as compared to what we're doing today, in the past we would build the same exact thing at many locations and then get a read on the full set of restaurants. Today, what we're doing is we're putting different elements into each restaurant so that we can compare what the drivers will be. And I think that's actually going to accelerate the learning. It's just a different approach. I think it's practical, and I'm hopeful that what will come out of this is a clear picture of what the winning elements are. The franchisees have been willing to build some of these. They love the new design. It really is compelling. It brings, not only in the logo and colors but also the design elements and the graphics, it really does bring a bold, grab-your-attention feel to the restaurant that, today, we just don't have. So our franchisees, I think, in -- are very enthusiastic about it and will be early adopters just based on what we're seeing so far.
