Good morning. My name is Chris and I will be your conference operator today. At this time, I would like to welcome everyone to the Biogen Fourth Quarter and Year End 2017 Financial Results and Business Update. All lines have been placed on mute to prevent any background noise. After the speakers’ remarks, there will be a question-and-answer session. [Operator Instructions] Thank you. I would now like to turn the conference over to Mr. Matt Calistri, Vice President, Investor Relations. You may begin your conference.
