Good day everyone and welcome to today’s CBOE Holdings First Quarter 2012 Earnings Conference Call. At this time, all lines are in a listen-only mode. Later we’ll conduct a question and answer session and instructions will be given at that time. (Operator Instructions). At this time for opening introduction, I’d like to turn the call over to Debbie Koopman, Vice President of Investor Relations. Please begin.
