Christine, it's David. On the first part, as we noted, one of the value creators we see for our 2 organizations is just what you said, expanding the focus and the ability to bring that physician partnership incentive and alignment model to the commercial space. And we see it 2 different ways. One, we see offering in capabilities to be brought forth for today's commercial employer market with a product and a choice alternative. And then secondly, we see an exciting set of opportunities to bring forward for what we'll call the evolving retailer individual market and you could use illustratively the 2014 exchanges and the ability to think about that. So point 1, we see that is a very important part of the opportunities in front of us. And Herb and his team share that, and early interaction that Herb's had with his physician partners, they see that and embrace that opportunity. As it relates to our ACO model, we see them as highly aligned. In some ways, Herb's model is more sophisticated and has driven the incentive alignment further and faster. But the overall ACO model we have, as I mentioned, we've entered our 15th very recently, shares the exact same framework. It's incentive alignment, it's the use of targeting the information to drive quality and service improvement, and it's care-coordination capabilities like case managers, nutritionists and the like. So philosophically, we align -- I would suggest that his model's a bit more sophisticated. As it relates to the 400,000 members, you should assume that our basic rule of thumb still holds. In the select segment, the level of specialty pullthrough is extraordinarily high. In the middle market, generally speaking, the level of specialty pullthrough is high, a little lesser than specialty. And then in the national accounts base, generally speaking, lower. The last comment I'll make is a string to pull throughout. Generally speaking, when we sell consumer-directed or high-engagement base capabilities, the level of specialty pullthrough is higher regardless of the segment because the employer understands the benefit of integration and the benefit of the overall program delivery, so it's a good trajectory there.
