Good morning. My name is Darla, and I will be your conference operator today. At this time, I would like to welcome everyone to Merck's First Quarter 2019 Sales and Earnings Conference Call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks, there will be a question-and-answer session.
