Good day, ladies and gentlemen, and welcome to the Nasdaq Fourth Quarter 2017 Results Conference Call. At this time, all participants are in a listen-only mode. Later, there will be a question-and-answer session, and instructions will follow at that time. [Operator Instructions] As a reminder, this conference call is being recorded. I'd now like to turn the conference over to Ed Ditmire, Vice President, Investor Relations. Sir, you may begin.
