Good day, ladies and gentlemen, and welcome to the First Quarter 2011 Exelixis Incorporated earnings conference call. My name is Shanelle, and I will be your operator for today. At this time, all participants are in a listen-only mode. Later we will conduct a question-and-answer session. (Operator Instructions) As a reminder, this conference is being recorded for replay purposes. I would now like to turn the conference over to your host for today, Mr. Charles Butler, Vice President of Investor Relations. Please proceed.
