Good morning. My name is Heidi, and I will be your conference operator today. At this time, I would like to welcome everyone to the Mastercard Q4 Full-Year 2018 Earnings Conference Call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks, there will be a question-and-answer session. [Operator Instructions] Thank you. Warren Kneeshaw, Head of Investor Relations, you may begin your conference, sir.
