We are a leader in the motion picture exhibition industry with 495 theatres and 5,676 screens in the U.S. and Latin America as of December 31, 2014.
We believe the following strengths allow us to compete effectively:
Experienced Management. Led by Chairman and founder Lee Roy Mitchell, Chief Executive Officer Tim Warner, President and Chief Operating Officer Robert Copple and President-International Valmir Fernandes, our operational management team has many years of theatre operating experience, ranging from 18 to 56 years, executing a focused strategy that has led to consistent operating results. This management team has successfully navigated us through many industry and economic cycles. Sean Gamble, the Company’s recently-hired Chief Financial Officer, brings approximately eight years of industry experience to the team, most recently working for a major studio.
Disciplined Operating Philosophy. We generated operating income and net income attributable to Cinemark Holdings, Inc. of $363.1 million and $192.6 million, respectively, for the year ended December 31, 2014. Our solid operating performance is a result of our disciplined operating philosophy that centers on building high-quality theatres, while maintaining favorable theatre-level economics, controlling operating costs and effectively reacting to economic and market changes.
Leading Position in Our U.S. Markets. We have a leading market share in most of the U.S. markets we serve, which includes a presence in 41 states. For the year ended December 31, 2014, we ranked either first or second, based on box office revenues, in 23 out of our top 30 U.S. markets, including the San Francisco Bay Area, Dallas, Houston, Salt Lake City, Sacramento and Austin.
Located in Top Latin American Markets. We have continued to invest throughout Latin America. As of December 31, 2014, we operated 160 theatres and 1,177 screens in 13 countries. Our international screens generated revenues of $704.6 million, or 26.8% of our total revenues, for the year ended December 31, 2014. We have successfully established a significant presence in major cities in the region, with theatres in twelve of the fifteen largest metropolitan areas in South America. We are the largest exhibitor in Brazil and Argentina. Our geographic diversity makes us an important distribution channel for the movie studios.
State-of-the-Art Theatre Circuit. We offer state-of-the-art theatres, which we believe makes our theatres a preferred destination for moviegoers in our markets. During 2014, we built 152 new screens worldwide. We currently have commitments to open 211 additional new screens over the next three years. We have installed digital projection technology in 100% of our U.S. first-run auditoriums and 100% of our international auditoriums. Currently, approximately 54% of our U.S. screens and 64% of our international screens are 3-D compatible. We currently have fourteen digital IMAX screens. As of December 31, 2014, we had the industry-leading private label premium large format circuit with 179 XD auditoriums in our theatres. We have plans to install 20 to 30 additional XD auditoriums during 2015. We also continue to develop new market-adaptive theatre concepts in various markets. We believe we offer the brightest picture in the industry, with our Doremi servers and Barco digital projectors, and custom surround sound in our auditoriums.
Disciplined and Targeted Growth Strategy. We continue to grow organically as well as through the acquisition of high-quality theatres in select markets. Our growth strategy has centered around achieving a target return on investment while also complementing our existing theatre circuit. We continue to generate significant cash flows from operating activities, which demonstrates the success of our growth strategy. We believe our expected level of cash flows will continue to provide us with the financial flexibility to pursue further growth opportunities, while also allowing us to efficiently service our debt obligations and continue to offer our stockholders a strong dividend yield under our current dividend policy.
Growth in Existing and New Markets. We continue to seek growth opportunities by building or acquiring high-quality theatres that meet our strategic, financial and demographic criteria. We also monitor economic and market trends to ensure our existing theatres offer a broad range of products, prices and platforms that satisfy our patrons and to develop new concepts to adapt to changes in preferences. Our growth strategy is diverse. During 2014, we acquired one theatre in Alabama, which is a new state for us, and we also built seven new theatres in six other states in the U.S. We also opened a state-of-the-art theatre in Bolivia during 2014 and we opened 11 other new theatres across four countries in our international markets. We have plans to expand into Paraguay and Curacao during 2016.
Focus on Operational Excellence. We continue to focus on achieving operational excellence by controlling theatre operating costs and training and motivating our staff while focusing on making each of our customer’s experiences memorable. We provide first-rate customer service and focus on driving attendance. Our consistent industry-leading margins reflect our ability to deliver the highest quality presentation to our patrons while also managing changes in product and consumer preferences.
Commitment to Technological and Product Innovation. Our commitment to technological innovation has resulted in us being 100% digital in our U.S. first-run auditoriums and international auditoriums as of December 31, 2014. Approximately 56% of our worldwide screens are 3-D compatible. See further discussion of our digital expansion under “Technology Innovations” on page 10. We continue to expand our worldwide XD auditorium footprint. We are also committed to developing new market-adaptive theatres that broaden the range of entertainment options, concession offerings and amenities we provide to our customers.
Sustained Investment in Existing Circuit. While we continue to grow our theatre circuit with new builds and acquisitions, we also remain committed to investing in our existing theatres to ensure they provide our customers with a comfortable, high-quality entertainment experience for our patrons. We spent approximately $125 million and $140 million on maintenance capital expenditures during the years ended December 31, 2013 and 2014, respectively.
