Chris, thanks for the question. Generally, what we'll offers is we aren't going to comment on Pfizer's plans. Frankly, we don't know the details of their plans and really, it's their prerogative to address those questions specifically. For Ligand, the opportunity that we would ask investors to explore, one, is the quality of the data. As we know, this is a combination drug. It involves a synthetic estrogen, bazedoxifene, which came out of our research labs; and Premarin, which is a well-known, well-established and, at one point, a very well liked drug in the medical community. It's low doses of both. And as we've commented, Pfizer, over the last 10, 15 years, has run extensive trials, really, a broad and exquisite set of studies that have produced a robust data package. The data are compelling. And so we'd invite investors to first just understand and look at the data as it relates to this category. The second thing is to consider how the landscape has changed. This market, this medical category, frankly, has been suppressed over the last 5 or 6 years in light of the initial conclusions coming out of the Women's Health Initiative research in the early 2000, a sense of whether or not women, postmenopausal women, should be on estrogen treatments and at what dose. The sentiment for treatment intervention, for the need for hormone replacement therapy, has changed significantly in the last 1 or 2 years. We have seen multiple HRT-related drugs approved. And it's our view, given what we know, that Duavive is really a standout medicine. It's got a very unique profile. So in that context, if you have a good data package, a unique drug profile and what is ostensibly a very large women's health category, the medical need is unquestioned. It's a very large category. Those are the factors that, from Ligand's perspective, we'd ask investors and analysts to spend some time doing research on. And as I said in my remarks, we are very eager to see the launch in the U.S., early part of 2014 and, of course, what the European action holds for the drug next year as well.
