Ladies and gentlemen, thank you for standing by. And welcome to the Fourth Quarter and Full Year 2017 Earnings Conference Call. All lines have been placed on mute to prevent any background noise. And after the speakers' remarks, there will be a question-and-answer session. [Operator Instructions] Thank you. I'll now turn the conference over to Mr. Guillermo Gutierrez. Please go ahead, sir.
