Focus on Providing an Extraordinary Guest Experience. We differentiate our theatres by focusing on providing an extraordinary guest experience through a variety of initiatives. We have a market-adaptive approach with our theatre amenities, including Luxury Lounger recliner seats, enhanced food and beverage offerings, and our private-label premium large format, XD. We also feature loyalty programs in our largest markets, including the U.S., Brazil, Argentina, Colombia and Central America, which allows us to perform advanced analytics for more insight about our guest preferences and further enrich their movie-going experience. Our new Movie Club membership program also rewards our frequent guests with specially-priced tickets, concessions discounts and other benefits. Our innovative and advanced technology selections allow us to consistently deliver the highest quality presentation to fully immerse our guests in the on-screen action. We train, motivate, and empower our staff to provide first-rate customer service, ensuring our guests are continually pleased with their Cinemark experience.
Grow Attendance. We believe our focus on the guest experience is a catalyst for attendance growth and is a primary factor in our consistent industry-leading results. In addition to optimizing schedules for Hollywood content, we also have initiatives to drive attendance during non-peak times, such as variable pricing strategies and alternative content, including both participatory and spectator e-sports, Metropolitan Opera, concerts, live and pre-recorded sports, gaming, and other special presentations and we continue to explore other alternatives. We recently announced plans to collaborate on an in-theatre virtual reality technology that will provide our guests with another entertainment experience in our theatres.
Sustain Investment in Core Circuit Combined with Targeted Growth. We continually utilize our cash flows from operations to invest in our existing circuit to ensure the highest quality experience for our guests. We routinely service and update theatre furniture, fixtures and equipment as well as invest in a variety of theatre upgrades such as Luxury Lounger recliner seats, enhanced food and beverage offerings, our XD private-label premium large format, and other entertainment features such as virtual reality and gaming. Our commitment to investing in our existing circuit is demonstrated by our level of maintenance capital expenditures for the years ended December 31, 2016 and 2017, at approximately $237.1 million and $322.6 million, respectively. We also continue to target organic growth throughout our global circuit and seek accretive acquisition opportunities, with the objectives of deeper market penetration in the territories in which we currently operate and as a means to enter new and developing markets. We built 66 new auditoriums and acquired 26 auditoriums during the year ended December 31, 2017.
As of December 31, 2017, we operated 533 theatres and 5,959 screens in 41 U.S. states and 15 Latin American countries. The following tables summarize the geographic locations of our theatre circuit as of December 31, 2017.
