Thank you, Sylvia. Good morning, good afternoon, and good evening to everyone listening around the world. Thank you for your interest in Regeneron Pharmaceuticals and welcome to the fourth quarter 2019 conference call.

After our prepared remarks, we will open the call for Q&A.I would also like to remind you that remarks made on today’s call include forward-looking statements about Regeneron. Such statements may include, but are not limited to those related to Regeneron and its products and business, financial forecasts and guidance, development programs and related anticipated milestones, collaborations, finances, regulatory matters, payer coverage and reimbursement issues, intellectual property, pending litigation and other proceedings and the competition.Each forward-looking statement is subject to risks and uncertainties that could cause actual results and events to differ materially from those projected in that statement. A more complete description of these and other material risks can be found in Regeneron’s filings with the United States Securities and Exchange Commission, including its Form 10-K, for the year ended December 31, 2019, which we are planning to file with the SEC tomorrow.Regeneron does not undertake any obligation to update publicly any forward-looking statements, whether as a result of new information, future events, or otherwise. In addition, please note that GAAP and non-GAAP measures will be discussed on today’s call. Information regarding our use of non-GAAP financial measures and a reconciliation of those measures to GAAP is available in our financial results press release, which can be accessed on our website. Additional information about those measures is also available on the Investor and Media section of our website.
