Good morning, ladies and gentlemen, and welcome to the Martin Marietta Fourth Quarter and Full Year 2017 Earnings Conference Call. My name is Jonathan, and I'll be your coordinator today. At this time, all participants have been placed in a listen-only mode. A question-and-answer session will follow the company's prepared remarks. As a reminder, today's call is being recorded. I would now like to turn the call over to your host, Ms. Suzanne Osberg, Vice President-Investor Relations for Martin Marietta. Ms. Osberg, you may begin.
