Good day, ladies and gentlemen, and thank you for standing by. Welcome to the MercadoLibre's Fourth Quarter 2017 Earnings Call. At this time, all participants are in a listen-only mode to prevent background noise. We will have a question-and-answer session later and the instructions will follow at that time. And as a reminder this conference is being recorded. Now, I would like to welcome and turn the call to Federico Sandler, Head of Investor Relations.
