Thank you, operator. Here today from BioMarin's management team are JJ Bienaimé, Chief Executive Officer; Dan Spiegelman, Chief Financial Officer; Hank Fuchs, Chief Medical Officer; Jeff Ajer, Chief Commercial; and Robert Baffi, Executive Vice President of Technical Operations. To remind you, this non-confidential presentation contains forward-looking statements about the business prospects of BioMarin Pharmaceutical, including expectations regarding BioMarin's financial performance, commercial products and potential future products in different areas of therapeutic research and development. Results may differ materially, depending on the progress of BioMarin's product program, actions of regulatory authorities, availability of capital, future actions in the pharmaceutical market and developments by competitors, and those factors detailed in BioMarin's filings with the Securities and Exchange Commission such as 10-Q, 10-K and 8-K reports. Now I'd like to turn the call over to BioMarin CEO, JJ Bienaimé.
JJ Bienaimé: Thank you, Traci. Good afternoon, and thank you for joining us on today's call. So in the 2014 BioMarin delivered $751 million in total revenues which represents 37% total revenue growth year-over-year, driven in part by the exceptionally successful launch of our newest commercial product, VIMIZIM for the treatment of MPS IVA or Morquio A Syndrome. In addition we advanced all of our clinical development programs and as a result of our acquisition of Prosensa we added multiple new potential products to our portfolio for the treatment of patients with Duchenne Muscular Dystrophy. So 2014 was by far our most productive year-to-date and we begin 2015 while positioned to achieving new set of significant regulatory clinical and commercial milestones. Hank will discuss our full slate of regulatory rejecters for 2015 but I want to highlight our later stage product Drisapersen for the treatment of 13% of the Duchenne Muscular Dystrophy patient population or about 10,000 patients. Drisapersen is currently under rolling submission with the FDA and we are on track to submit the last module of the new drug application to the FDA by the end of April. In addition we expect to submit an application to the European Medicine Agency this summer and with the near term approval of Drisapersen in either of the US or Europe, we believe that we will reach profitability on a non-GAAP basis in 2017 and drive to further substantial profitability in the years after that. We continue to be optimistic that there is a potential pathway to near term approval for Drisapersen based on a number of factors. Some of the key factors are the urgent need for an improved treatment for boys with Duchenne Muscular Dystrophy. This entirely of our comprehensive dataset of over 300 patients treated with Drisapersen around the world and specifically the data that spans more than three years from three placebo controlled trials and two long term open label trials. Importantly, BioMarin has a track record of getting approval of orphan drugs based on a mixed dataset, and even mixed primary end points as evidenced by our product Aldurazyme. Our experience is consistent with FDAs record having approved 90 non-cancer orphan drugs without conventional evidence including many that have missed their primary endpoints. We are encouraged by the interactions we've had with the agency over the past few weeks and we look forward to a potential advisory committee meeting later on this year. On the commercial front, Jeff’s team did an exceptional job in 2014 launching VIMIZIM, driving first year product revenue to over $77 million. Moreover, we generated $751 million in total BioMarin revenue. Looking forward to 2015 we expect VIMIZIM revenues to continue growing as it penetrates more of the over 1,650 patients we have already identified. Then we'll describe more fully, we expect total BioMarin revenues to grow to $840 million to $870 million in 2015, although it is important to note that this guidance is based on current exchange rate and that demand is growing such that we would have been expecting $885 million to $915 million into our revenues for 2015 based on last year's exchange rate. In conclusion, we entered 2015 with a strong balance sheet, a portfolio of five marketed products and a pipeline of ten clinical and preclinical programs from which we expect a number of milestones and their readouts during the coming year. In the very near term we expect to complete the rolling NDA for approval of Drisapersen first in the US for treatment of patients with Muscular Dystrophy and shortly thereafter submission of the marketing authorization application for conditional approval of Drisapersen with the European Medicine Agency. We believe near term approval of Drisapersen in either of diseases will drive us to profitability on a non-GAAP basis in 2017. Till our accomplishments in 2014 I've set the stage for a very productive year both in terms of commercial success and clinical and regulatory milestones. We look forward to keeping you apprise of these important events throughout the year. And now Dan will discuss the 2014 quarterly and full year financial results in more detail, as well as provide our financial guidance for 2015. Dan?
