For the two full years into executing the Velocity Growth Plan, our strategy remains focused on [indiscernible] guest count momentum and regaining customer visits. We're visibly demonstrating to our customers how we're becoming a better McDonald's with a robust range of initiatives. With our focus on improving the taste of our delicious food, enhancing convenience, offering compelling value, upholding the trust consumers place in our brands, we are maximizing our opportunity to improve customer perceptions and encourage more visits. We continuously strive to improve the taste of the iconic sandwiches at the core of our menu and introducing items to even to customers. During the quarter, we have many examples in markets of how success and encouraging visits and sales with menu changes. In Germany, customers continue to enjoy iconic favorites on the Taste of McDonald's platform such as the McChicken. Canada extended the successful launch of bagels earlier in the year by introducing All Day Breakfast Bagel Sandwiches with fresh cracked eggs. In Spain, [indiscernible] drives the popular customers seeking a snack and many also enjoyed adding them on to a meal. Last year Canada had a successful promotion introducing bacon on some of our classic sandwiches and this week the U.S. launched a similar campaign to encourage more visits to our restaurants. We were pleased to see the attention generated with yesterday's bacon events and the U.S. is following up by offering Bacon Big Macs and Quarter Pounders as well as cheesy bacon fries. Time and again we see the importance customers place on getting their food hot and fresh with fast, friendly service. Customers notice a difference when we run great restaurants and we continue to focus on improving the operations of our restaurants to provide customers with great all-round experience. I'm encouraged by the greater discipline we're demonstrating in many of our markets as I simplify menus, take other actions that reduce complexity and improve our ability to provide exceptional experiences for our customers. Serving delicious food and offering great service are vital, but not the only requirements for maintaining strong trust to consumers. Public expectations are leading companies like McDonald's have never been higher. In December we announced that we are partnering with suppliers and beef producers to reduce the overall use of antibiotics in our beef supply chains. This is the latest in a series of announcements throughout 2018 but we detailed both targets by using our scale for good and addressing some of the world's most pressing challenges. In committing our resources, attention and significant convenient power and influence, we are demonstrating to our customers, employees and other stakeholders that McDonald's is worthy of their trust. 2018 also marked a year of significant progress with each of our Velocity, accelerated delivery, Experience of the Future and digital. We will take action in 2019 to capture additional growth opportunities within the Velocity strategy. Delivery momentum continues and is now available for over 19,000 restaurants, over half of our global system. It took us almost 20 years to grow our annual delivery business in the Middle East and Asia to $1 billion. Over the past two years, delivery has become a $3 billion business for both McDonald's company and franchise restaurants globally. Delivery continues to grow rapidly as we expand through additional restaurants and third-party providers as well as benefiting from strong same-store sales momentum. Many of our major markets such as to the U.S., France and in the U.K. achieved delivery sales growth in the high double-digits in restaurants offering a service for more than 12 months and other markets such as Canada, Italy and Russia grew even more. We’re confident this delivery offers additional growth potential for our business. Even with the momentum we already have established, we know we have an opportunity to let more customers know the McDonald's will bring meals to their homes, offices and college dorm rooms. Driving awareness begins with encouraging more customers to try delivery. We talked before about the high satisfaction among our delivery customers and their willingness to reorder and we continue to see those trends hold steady throughout 2018. We placed a high priority on identifying the winning ideas developed by individual markets and spreading them elsewhere within the McDonald's system. With delivery, U.K. Canada and Australia are leaders within McDonald's and are developing innovative approaches to help restaurants with high order volumes. In Australia, awareness more than doubled through a major campaign of promotional delivery within-restaurant signs, engaging social media outreach, PR activity and advertising. And in its own awareness campaign, Uber Eats in Australia featuring McDonald's demonstrating the strength of our partnership. We also continue to bring learning from China, our most developed delivery market, to help our newer delivery markets, especially related to restaurant operations. As we have said previously, underpinning everything we do with this growth accelerator is our commitment to make delivery easy and convenient for our customers, which will help us maximize the competitive advantage of our business. Now I'll turn to another one of our Velocity accelerators, Experience of the Future. The refreshed decor, new ordering options and an enhanced focus on providing more enjoyable visits to our restaurants, we're introducing a new hospitality experience to McDonald's customers. Our guest experience of years have been the key to a better customer experience, which we've seen drive high customer satisfaction and sales and ultimately, strong business results. With about half of our restaurants around the world converted to EOTF, we have many more customers experience modernized restaurants and enhanced hospitality. We've identified an opportunity to be more consistent in assuring restaurants as proven best practices for engaging with customers in our updated restaurants. We've made significant progress for example in the U.S. in training tens of thousands of additional guest experience leaders to greet our guests with enthusiastic smile, assist the customer with kiosk orders, offering trays of Big Macs and fries to a customer's table. We're encouraged by the impacts on our business as we continue to enhance hospitality and complete more projects. Restaurants that have introduced Experience of the Future elements continue to perform in line with our expectations with higher sales and customer satisfaction. Customer expectations for the way they interact with brands continue to rise. We have made additional progress in 2018 rolling out digital platforms, making the McDonald's experience simpler and more personalized for our customers. In the years ahead, we will continue making strides through digital channels to reward customers with good value and relevant offers as well as incorporating fun experiences they appreciate from our brands. These opportunities are possible because the extensive work we completed in deploying technology throughout the McDonald's system, including self-order kiosks in nearly 17,000 restaurants, digital menu boards in more than 21,000 restaurants and new capabilities from low bottle room pay as available in over 22,000 restaurants. Now Kevin will discuss our outlook for 2019.
