Good day, Ladies and Gentlemen, and welcome to the First Quarter 2012 Exelixis’ Financial Results Conference Call. My name is Keisha and I'll be your operator for today. At this time, all participants are in listen-only mode. Later, we will conduct the question-and-answer session. (Operator instructions). As a reminder, this conference is being recorded for replay purposes. I would now like to hand the conference over to Mr. Charles Butler, Vice President of Investor Relations. Please proceed.
