Ana, it's Ralph. First, there's a lot of moving parts in all this. So let me, in a couple of parts to your question. First, overall, we came in at where we expected. And in the first -- just to remind you on our guaranteed cost of book of business, again, a small piece of our total portfolio, but having said that, came in as we expected. Essentially, you're a year flat. Also, what you see -- back on the comment you made on the payable, there's some noise in there because we exited the Private Fee for Service business and so as those liabilities ran out, you see a reduction in those liabilities. So when you strip that out, it's a fairly even level year-to-year. So that has some noise in the numbers looking year-on-year. And then I think, also importantly, in the fourth quarter you see a jump year-on-year, quarter-on-quarter. Again, full year, it's essentially where we expected, essentially flat. In the quarter, you see a big jump. Because just the prior period development flow into the fourth quarter of 2010 was significantly higher than the flow of prior period development on our guaranteed cost book of business in the fourth quarter this year. So there was about a 400 basis-point swing, and it's all because of that. So absent the change in the prior period flow, we're essentially flat year-on-year.
Ana Gupte - Sanford C. Bernstein & Co., LLC., Research Division: Okay, so follow-up on that. It sounds like pricing, and my math tells me it's okay. Days and claims payable, you're attributing it to pricing. And then the MLR largely to a reserve headwind. Going forward, can you tell us what your -- is being embedded in your outlook for Health Care in terms of your cost trend? And would you be able to highlight the puts and takes in terms of the tailwinds from possibly unit costs, the reform provisions, which are one-time, and then possible headwinds from COBRA which you don't see now, utilization if you're seeing, or -- and what exactly are you embedding in your expectations?
