The Las Vegas Operating Properties, situated on the Las Vegas Strip, is an Integrated Resort with approximately 7,100 suites; approximately 225,000 square feet of gaming space; 2.3 million gross square feet of state-of-the-art exhibition and meeting facilities that can be configured to provide small, mid-size or large meeting rooms and/or accommodate large-scale multi-media events or trade shows. The Company is working with Madison Square Garden Company to bring a 400,000-square-foot venue built specifically for music and entertainment to Las Vegas. Madison Square Garden is currently building the MSG Sphere at The Venetian, an 18,000-seat venue, which will be located near, with connectivity to, the Las Vegas Operating Properties and is currently expected to open in 2021. Pennsylvania The Company previously owned and operated the Sands Casino Resort Bethlehem (the "Sands Bethlehem") in Bethlehem, Pennsylvania. On May 31, 2019, the Company closed the sale of Sands Bethlehem and received $1.16 billion in net cash proceeds and recorded a gain on the sale of $556 million. As there is no continuing involvement between the Company and Sands Bethlehem, the Company accounted for the transaction as a sale of a business. The Company concluded Sands Bethlehem does not have a material impact on the Company's overall operations or its consolidated financial results. Subsequent Events In early January 2020, an outbreak of a respiratory illness caused by a novel coronavirus was identified in Wuhan, Hubei Province, China. On February 4, 2020, the Macao government announced the suspension of casino operations from February 5, 2020. Additionally, there are travel restrictions such as those related to the China Individual Visit Scheme to Macao, the Hong Kong Macao Ferry Terminal closure and other countries restricting inbound travel from mainland China. The duration and intensity of this global health emergency and related disruptions is uncertain, including potential broader impacts outside of China if travel and visitation continues to be restricted and there is a resulting decline in Chinese tourist spending in Singapore or Las Vegas. Given the dynamic nature of these circumstances, the related impact on the Company’s operating segments in Macao and our consolidated results of operations, cash flows and financial condition will be material, but cannot be reasonably estimated at this time. Development Projects The Company regularly evaluates opportunities to improve its product offerings, such as refreshing its meeting and convention facilities, suites and rooms, retail malls, restaurant and nightlife mix and its gaming areas, as well as other anticipated revenue generating additions to the Company's Integrated Resorts. Macao The Company previously announced the renovation, expansion and rebranding of the Sands Cotai Central into a new destination Integrated Resort, The Londoner Macao, by adding extensive thematic elements both externally and internally. The Londoner Macao will feature new attractions and features from London, including some of London’s most recognizable landmarks, such as the Houses of Parliament and Big Ben. The expanded retail will be rebranded as the Shoppes at Londoner and a number of new restaurants and bars will be added. The Londoner Tower Suites will add approximately 370 luxury suites. Upon completion of the project, the Holiday Inn-branded rooms and suites will be converted to approximately 600 London-themed suites, referred to as The Londoner Macao Hotel. The Company is utilizing suites as they are completed on a simulation basis for trial and feedback purposes. Construction has commenced and is being phased to minimize disruption during the property’s peak periods. The Company expects The Londoner Tower Suites to be completed in late 2020 and The Londoner Macao project to be completed in phases throughout 2020 and 2021. The Company also previously announced The Grand Suites at Four Seasons, which will feature approximately 290 additional premium quality suites. The Company has initiated approved gaming operations in this space and is utilizing suites as they are completed on a simulation basis for trial and feedback purposes. The Company expects the project to be completed in the first half of 2020. The Company anticipates the total costs associated with these development projects to be approximately $2.2 billion. The ultimate costs and completion dates for these projects are subject to change as the Company finalizes its planning and design work and completes the projects. Singapore In April 2019, MBS entered into the Second Development Agreement with the Singapore Tourism Board pursuant to which MBS has agreed to construct a development, which will include a hotel tower with approximately 1,000 rooms and suites, a rooftop attraction, convention and meeting facilities and a state-of-the-art live entertainment arena with approximately 15,000 seats. The Second Development Agreement provides for a total project cost of approximately 4.5 billion Singapore dollar ("SGD," approximately $3.3 billion at exchange rates in effect on December 31, 2019), which investment must be completed within eight years from the effective date of the agreement. The amount of the total project cost will be finalized as the Company completes design and development and begins construction. United States The Company was constructing a high-rise residential condominium tower (the "Las Vegas Condo Tower"), located on the Las Vegas Strip within The Venetian Resort Las Vegas. In 2008, the Company suspended construction activities for the project due to reduced demand for Las Vegas Strip condominiums and the overall decline in general economic conditions. The Company continues to evaluate the highest return opportunity for the project. The impact of the suspension on the estimated overall cost of the project is currently not determinable with certainty. Should demand and conditions fail to improve or management decides to abandon the project, the Company could record a charge for some portion of the $129 million in capitalized construction costs (net of depreciation) as of December 31, 2019. Other The Company continues to evaluate current development projects in each of its markets and pursue new development opportunities globally.
