Thank you, Francesco. During Q2, we made important advancements on several aspects of our R&D program and, as George mentioned, attained a significant milestone for TYSABRI risk stratification. Last month, the European Commission approved an update to the TYSABRI label to include the presence of anti-JC virus antibody as a risk factor for PML. We now have a 3-pronged approach for risk stratification, demonstrating different levels of PML risk and allowing for a more personalized benefit risk discussion for each patient on or considering TYSABRI. This update to the EU label was supported by analysis of data and our quantitative risk stratification algorithm. In the analysis, patients who were anti-JCV Antibody negative had the lowest risk for developing PML. For patients who are anti-JCV Antibody positive, the risk of PML in patients with less than 2 years of TYSABRI treatment and no prior immunosuppressant usage was estimated at 0.4 per 1,000. And this risk increased to 2.6 per 1,000 for patients with TYSABRI exposure between 2 and 4 years. For patients with less than 2 years of TYSABRI treatment and prior immunosuppressant history, the risk of PML was estimated at 1.2 per 1,000. The highest risk category was identified with all 3 risk factors, which includes anti-JCV antibody positive status, prior immunosuppressant usage and greater than 2 years of TYSABRI treatment. For these patients, the risk of PML was estimated at almost 9 per 1,000. We believe that approximately 10% of all MS patients are JCV Antibody positive and have prior immunosuppressant history. In Europe, physicians and patients are now equipped to make better-informed decisions about their treatment with TYSABRI either through the commercial JCV assay or via participation in JEMS, which stands for the JCV Epidemiology in MS Study. As of mid-July, we enrolled over 3,000 patients in JEMS. In the U.S., we expect a decision -- an FDA decision on our sBLA filing for TYSABRI in October. Also, we expect to make the assay commercially available in the coming months as a laboratory-developed test. In the meantime, patients have access to the assay via the STRATIFY 2 study, which, through mid-July, enrolled about 28,000 patients. With regards to our hemophilia franchise, we shared important data today at the 23rd Congress of the International Society on Thrombosis and Haemostasis in Kyoto, Japan. Six out of our 8 abstracts were platform presentations and focused on the advancements of our hemophilia programs. One presentation that I'll highlight includes a Phase I 2a study of our long-lasting fully recombinant Factor VIII Fc fusion protein, which showed that the drug demonstrated on approximately 1.7 fold increase in half-life compared with Advate, a commercially available Factor VIII product in 16 previously treated patients with severe hemophilia A. Our long-lasting recombinant Factor VIII had comparable -- in dose-dependent peak plasma concentration, comparable recovery but reduced clearance relative to Advate. Importantly, no inhibitor formation was observed. These data indicate that there would be 50 to 80 less injections per year for hemophilia A patients. During this quarter, we also made progress on all of our registrational trials. Some updates include CONFIRM, the second Phase III study of BG-12 in MS, is on track for data readout in the second half of this year. CONFIRM is a 2-year placebo-controlled dose comparison study. In order to fulfill EU regulatory requirements, the study includes a glatiramer acetate reference comparator arm. Trial is not powered for superiority or non-inferiority versus glatiramer acetate. CONFIRM's primary endpoint is annualized relapse rate at 2 years for BG-12 versus placebo. We will present detailed results from DEFINE, the first Phase III study of BG-12 at ECTRIMS in October in Amsterdam. We expect data readout for SELECT, the first registration enabling study of daclizumab in MS to be this summer. Dac has the potential for treating MS with a convenient once monthly subcutaneous administration. The drug targets the pathogenic activated T-cells in MS through a novel mechanism, and a prior Phase II study showed promising efficacy and safety data. ADVANCE, the Phase III trial of PEGylated interferon for MS, is planned to complete enrollment by year end. This trial is conducted under a special protocol assessment with the FDA. With a one-year treatment duration, an annualized relapse rate is the primary endpoint. We expect top line data to be available in early 2013. We've activated over 80% of the clinical sites in EMPOWER, the Phase III study of dexpramipexole in ALS. All countries participated have at least one center activated. We and our partner, Knopp Biosciences, are very excited about the enthusiasm that we've received from both healthcare providers and patients for participation in this international trial. Lastly, we're pleased with the rate of enrollment for B-LONG and A-LONG, the registrational trials of long-lasting recombinant Factor IX and Factor VIII, that are on track for readout in 2012. For both of our hemophilia A and B programs, we and our partner, Swedish orphan Biovitrum, plan to initiate a global pediatric trial in previously treated patients under 12 years of age as soon as sufficient data are available from a study in older patients. Moving on to our early-stage pipeline programs, I want to highlight 3. First, our Phase I study of Anti-LINGO in MS continues to progress on track with data readout expected in early 2012. Primary analysis of the single and multiple ascending dose cohorts will include various safety metrics and pharmacokinetic data, as well as measurements of antibody levels in the CSF. Another important early-stage program is neublastin, an endogenous neurotrophic factor, the receptor for which is predominantly expressed in pain-sensing neurons in the peripheral nervous system. Based on animal studies, the drug has shown a reduction of pain behaviors to the neuropathic pain state. Phase I study includes both single and multiple ascending dose cohorts, and we expect data readout for the single ascending portion of the trial in the first half of 2012. Third, we've initiated dosing now in the Phase I study of BIIB037, our fully humanized anti-A beta monoclonal antibody, also known as BART in Alzheimer's disease patients. We expect data readout in the second half of 2012. Let me wrap up with a brief organizational update. As George told you earlier, we continue to make progress on our R&D invigoration efforts to build a world-class R&D organization. I’m very excited to announce the addition of 3 key hires. First, Dr. Tim Harris, as the Senior Vice President of our Translational Medicine Group. Tim joined us from NCI-Frederick, where he was Chief Technology Officer and Director of the Advanced Technology Program. Tim will provide leadership in our efforts for personalized medicine. His group will focus on molecular, serologic or cell-based markers to identify patients most likely to benefit from our drugs and drug candidates. Our efforts with PML risk stratification is just one example of putting those approaches into practice. Second, Dr. Jo Viney, as the Vice President of Immunology Research. Jo joins us from Amgen, where she was Executive Director of Research Inflammation and led the discovery and development of novel therapeutics for autoimmune and inflammatory diseases. Jo will provide strategic direction and scientific leadership for our immunology research efforts. And third, Dr. Teresa Compton, as Vice President of Virology Research. She'll be taking the leadership role with our PML research efforts. Teresa joins us from Novartis, where she was Executive Director of Infectious Diseases. The addition of Teresa shows our commitment to risk stratification. In summary, I'm pleased with the progress the R&D organization has attained this quarter, especially with the TYSABRI EU label and turning around the FAMPYRA appeal. I look forward to providing you with further updates on our progress in the coming quarters. With that, I'll now pass the call to Paul Clancy, our Chief Financial Officer.
