Ladies and gentlemen, thank you for standing by and welcome to the Gilead Sciences Third Quarter 2013 Earnings Conference Call. My name is Erika and I'll be your conference operator today. At this time, all participants are in a listen-only mode. And as a reminder, this conference call is being recorded. I would now like to turn the call over to Patrick O'Brien, Vice President of Investor Relations. Please go ahead.
