Good day, ladies and gentlemen, and welcome to the CBOE Holdings Fourth Quarter 2012 Earnings Call. At this time, all participants are in a listen-only mode. Later we will conduct a question-and-answer session and instructions will follow at that time. (Operator Instructions) As a reminder, this conference call is being recorded. I would now turn the conference over to your host Debbie Koopman, please go ahead.
