We are a leader in the motion picture exhibition industry with 490 theatres and 5,629 screens in the U.S. and Latin America as of September 30, 2014.
Cinemark has a unique operating philosophy which combines finding the right markets in which to expand, having high-quality, right-sized theatres, and a strong operating discipline, resulting in strong operating performance. We have grown through organic expansion and selective acquisitions, creating a diverse footprint of high quality theatres in high growth markets with superior demographics.
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, Chief Operating Officer and Chief Financial Officer Robert Copple and President-International Valmir Fernandes, our management team has many years of theatre operating experience, ranging from 17 to 55 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.
Disciplined Operating Philosophy. We generated operating income and net income attributable to Cinemark Holdings, Inc. of $415.5 million and $148.5 million, respectively, for the year ended December 31, 2013. Our solid operating performance is a result of our disciplined operating philosophy that centers on building high-quality market-adaptive theatres, while negotiating 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 the U.S. metropolitan and suburban markets we serve. For the year ended December 31, 2013, 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 Pittsburgh.
Located in Top Latin American Markets. Since 1993, we have invested throughout Latin America in response to the continued growth of the region. As of December 31, 2013, we operated 148 theatres and 1,106 screens in 12 countries. Our international screens generated revenues of $783.1 million, or 29.2% of our total revenues, for the year ended December 31, 2013. We have successfully established a significant presence in major cities in the region, with theatres in thirteen 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 2013, we opened 709 new state-of-the-art screens worldwide. We currently have commitments to open 263 additional new screens over the next three years. We have installed digital projection technology in 100% of our U.S. first-run auditoriums and approximately 86% of our international auditoriums, with plans to install digital projection technology in 100% of our international auditoriums in early 2014. Currently, approximately 52% of our U.S. screens and 58% of our international screens are 3-D compatible. We currently have fourteen digital IMAX screens. As of December 31, 2013, we had the industry-leading PLF circuit with 150 XD auditoriums in our theatres. We have plans to install 45 to 55 additional XD auditoriums during 2014. We also continue to develop new theatre concepts in various markets.
Disciplined 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 will 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 develop new concepts to adapt to our patrons’ preferences. Our growth strategy is diverse. We opened two locations with our new Cinemark Movie Bistro concept during 2013 and have plans to open two theaters in the U.S. with our new premium concept during 2014. We also have plans to open state-of-the-art theatres in Bolivia in 2014 and Paraguay during 2015.
Continue to Focus on Operational Excellence. We will continue to focus on achieving operational excellence by controlling theatre operating costs and adequately training and motivating our staff while continuing to provide leading customer service. Our consistent margins reflect our ability to anticipate and manage changes in product and patron preferences.
Commitment to Technological Innovation. Our commitment to technological innovation has resulted in us being 100% digital in our U.S. first-run auditoriums as of December 31, 2013, 2,329 of which are 3-D compatible. Approximately 86% of our international auditoriums were digital as of December 31, 2013, 644 of which are 3-D compatible. See further discussion of our digital expansion at “Technology Innovations”. We expect to be 100% digital worldwide in early 2014, with approximately 50-60% of our screens 3-D compatible. We will also continue to expand our worldwide XD auditorium footprint.
