Good day ladies and gentlemen, and welcome to the Mammoth Energy Services' Fourth Quarter and Full-Year 2017 Earnings Conference 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. As a reminder, this conference call is being recorded and will be available for replay on Mammoth Energy Services' website. I would now like to introduce your host for today's conference, Mr. Don Crist, Mammoth Energy Services' Director of Investor Relation. Sir, you may begin.
