Yes, thank you, Lamberto. This is Giovanni. So building on what Lamberto said. Clearly, we are very focused on the profile of ELIQUIS and the differentiated profile of ELIQUIS not only versus warfarin, but also versus the other new agents, because of the benefit in efficacy, bleeding and mortality versus warfarin. Lamberto mentioned our and Pfizer's legacy in CV. In the U.S., we are also are very excited with the fact that we truly have complementary capabilities. We at BMS, for example, develop strong expertise in the hospital setting, Pfizer is very experienced with integrated healthcare systems in the U.S., and they clearly have with us a broad reach in primary care. So we are focusing very actively on preparing for launch, and working together to leverage our complementary capability and experience in this disease area. Regarding launch and uptake, we have learned that establishing early access and reimbursement is very critical to a successful launch. And that will be our focus in the first 4 to 6 weeks after we receive approval. During that period, which will likely be during the summer months, we will also be focusing on training our sales force and medical organizations to begin promoting and supporting the product. Once we begin to promote, we expect that the primary opportunity for ELIQUIS at launch will be to compete for new patient starts and patients who are no longer well-controlled on warfarin. And based on our profile, we plan on working to establish ELIQUIS as the leading new agent for these patients. Over time, as physicians become more comfortable with the profile of ELIQUIS and its overall value, we believe that other patient segments such as those on aspirin or switches from patients that are controlled on warfarin could become significant opportunities. In the long term, the size of the opportunity of ELIQUIS will ultimately be dependent on a number of factors: The incidence of A-fib and how it grows annually; the evolution of the percentage of patients that get treated; the share that new agents capture, and within that, our share with ELIQUIS; and finally duration of therapy. So in summary, we're excited with the profile of the product, with Pfizer as 2 companies which have significant experience in CV, but also complementary capabilities in the U.S. market. We're working very hard to prepare to launch, and we will be ready to execute the commercial launch when we're approved by the FDA.
