Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business of Company	Organization and Business of Company The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K of Las Vegas Sands Corp. ("LVSC"), a Nevada corporation, and its subsidiaries (collectively the "Company") for the year ended December 31, 2017, and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to such rules and regulations; however, the Company believes the disclosures herein are adequate to make the information presented not misleading. In the opinion of management, all adjustments and normal recurring accruals considered necessary for a fair statement of the results for the interim period have been included. The interim results reflected in the unaudited condensed consolidated financial statements are not necessarily indicative of expected results for the full year. The Company's common stock is traded on the New York Stock Exchange under the symbol "LVS." The ordinary shares of the Company's subsidiary, Sands China Ltd. ("SCL," the indirect owner and operator of the majority of the Company's operations in the Macao Special Administrative Region ("Macao") of the People's Republic of China), are listed on The Main Board of The Stock Exchange of Hong Kong Limited ("SEHK"). The shares were not, and will not be, registered under the Securities Act of 1933, as amended, and may not be offered or sold in the U.S. absent a registration under the Securities Act of 1933, as amended, or an applicable exception from such registration requirements. The Company currently owns 70.0% of SCL. The Company has entered into various joint venture agreements with independent third parties, which have been consolidated based on accounting standards for variable interest entities. As of June 30, 2018 and December 31, 2017, the Company's consolidated joint ventures had total assets of $76 million and $77 million, respectively, and total liabilities of $211 million and $198 million, respectively. The Company's joint ventures had intercompany liabilities of $209 million and $196 million as of June 30, 2018 and December 31, 2017, respectively. On March 8, 2018, the Company entered into a purchase and sale agreement under which PCI Gaming Authority, an unincorporated, chartered instrumentality of the Poarch Band of Creek Indians, will acquire the Sands Bethlehem property in Pennsylvania for a total enterprise value of $1.30 billion. The closing of the transaction is subject to regulatory review and other closing conditions. Development Projects The Company is constantly evaluating 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 In October 2017, the Company announced it will renovate, expand and rebrand 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, an expanded retail mall and approximately 370 additional luxury suites in the St. Regis Macao Tower. Design work has commenced and construction will be phased to minimize disruption during the property’s peak periods. The Company expects the project to be completed in 2020. In October 2017, the Company also announced the tower adjacent to the Four Seasons Hotel Macao will feature approximately 280 additional premium quality suites. The Company has completed the structural work of the tower and plans to commence build out of the suites in 2018. The Company expects the project to be completed in 2019. The completion dates for these projects are subject to change as the Company continues its planning and design work. Capital Financing Overview The Company funds its development projects primarily through borrowings under its credit facilities and operating cash flows. As of June 30, 2018 and December 31, 2017, the Company held cash, cash equivalents and restricted cash of $4.36 billion and $2.43 billion, respectively. Restricted cash represents those amounts contractually reserved for substantial mall-related repairs and maintenance expenditures. Cash equivalents are short-term investments with original maturities of less than 90 days and are carried at cost, which is a reasonable estimate of their fair value. The estimated fair value of the Company's cash equivalents is based on level 1 inputs (quoted market prices in active markets). The Company believes the cash on hand and cash flow generated from operations will be sufficient to maintain compliance with the financial covenants of its credit facilities. In the normal course of its activities, the Company will continue to evaluate its capital structure and opportunities for enhancements thereof. In March 2018, the Company amended its Singapore credit facility, which refinanced the facility in an aggregate amount of 4.80 billion Singapore dollars ("SGD," approximately $3.51 billion at exchange rates in effect on June 30, 2018), extended the maturities of the term loans and revolving loans to March 29, 2024 and September 29, 2023, respectively, and amended the amortization schedule and the leverage covenant to provide that the leverage ratio not exceed 4.0x for all quarterly periods through maturity (see "— Note 4 — Long-Term Debt — 2012 Singapore Credit Facility"). In March 2018, the Company also amended its U.S. credit facility, which refinanced the term loans in an aggregate amount of $2.16 billion, extended the maturity of the term loans to March 27, 2025, and reduced the applicable margin credit spread for borrowings under the term loans. In June 2018, the Company further amended its U.S. credit facility to, among other things, increase the amount of the term loans by $1.35 billion, to an aggregate amount of $3.51 billion (see "— Note 4 — Long-Term Debt — 2013 U.S. Credit Facility"). Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued an accounting standard update (as subsequently amended) on revenue recognition applicable to all contracts with customers. The update requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects to receive in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted the new standard on January 1, 2018, on a full retrospective basis (see disclosures at "— Note 2 — Revenue"). In February 2016, the FASB issued an accounting standard update on leases, which requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company will adopt this guidance beginning January 1, 2019. Although the Company is in the process of evaluating the impact the guidance will have on its financial condition and results of operations, the Company currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company's balance sheet for real estate operating leases. The adoption of this guidance is not expected to have a material effect on net income. In June 2016, the FASB issued an accounting standard update that revises the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The guidance is effective for fiscal years beginning after December 15, 2019, including interim reporting periods within that reporting period, and should be applied on a modified retrospective basis, with early adoption permitted. The Company is currently assessing the effect the guidance will have on the Company's financial condition and results of operations. In August 2016, the FASB issued an accounting standard update to reduce the diversity on how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In November 2016, the FASB issued an accounting standard update to reduce the diversity on how changes in restricted cash are presented and classified on the statement of cash flows. The Company adopted this guidance on a retrospective basis as of January 1, 2018. The adoption did not have a material effect on the presentation of its statement of cash flows. Reclassification Certain amounts in the accompanying condensed consolidated balance sheet as of December 31, 2017, and the related condensed consolidated statements of operations, comprehensive income, equity and cash flows for the three and six months ended June 30, 2017, have been reclassified to be consistent with the current period presentation.
